    A population-based study of cellular markers in R-CHOP treated diffuse large B-cell lymphoma patients2016In: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 55, no 9-10, p. 1126-1131Article in journal (Refereed)
    Abstract [en]

    Aim: To determine the prognostic significance of co-expression of MYC, BCL-2 and BCL-6 proteins in combination with other biomarkers and clinical characteristics within a population-based cohort of diffuse large B-cell lymphoma (DLBCL) patients uniformly treated with R-CHOP.

    Patients and methods: The immunohistochemical (IHC) expression of CD10, BCL-2, BCL-6, MUM1, MYC, CD5, CD30, Ki-67 and p53 was evaluated in a retrospective, population-based study comprising 188 DLBCL patients treated with R-CHOP and diagnosed in Sweden between 2002 and 2012.

    Results: Patients had a median age at diagnosis of 64 years (26-85 years) with a male:female ratio of 1.4:1. Approximately half (52%) of the patients presented with an International Prognostic Index (IPI) age adjusted (IPIaa)2. Median follow-up time was 51 months (range 0.4-158) and the five-year lymphoma-specific survival (LSS) was 76%, five-year overall survival (OS) was 65% and five-year progression-free survival (PFS) was 61%. A high Ki-67 value was found in 59% of patients, while p53 overexpression was detected in 12% of patients and MYC, BCL-2 and BCL-6 expression were detected in 42%, 55% and 74% of patients, respectively. IPIaa2 (p=0.002), Ki-6770% (p=0.04) and p53 overexpression50% (p=0.02) were associated with inferior LSS and OS. Co-expression of both MYC (>40%) and BCL-2 (>70%) proteins was detected in 27% of patients and correlated with a significantly inferior LSS (p=0.0002), OS (p=0.009) and PFS (p=0.03). In addition, triple expression of MYC, BCL-2 and BCL-6, also correlated with a significantly inferior LSS (p=0.02).

    Conclusion: Concurrent expression of MYC and BCL-2 proteins, as detected by IHC, was strongly associated with an inferior survival in DLBCL patients treated with R-CHOP. Other markers affecting survival were triple expression of MYC, BCL-2 and BCL-6, IPIaa, high Ki-67 and p53 overexpression.

    Brain tissue Aβ42 levels are linked to shunt response in idiopathic normal pressure hydrocephalus2018In: Journal of Neurosurgery, ISSN 0022-3085, E-ISSN 1933-0693, p. 1-9Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE The authors conducted a study to test if the cortical brain tissue levels of soluble amyloid beta (Aβ) reflect the propensity of cortical Aβ aggregate formation and may be an additional factor predicting surgical outcome following idiopathic normal pressure hydrocephalus (iNPH) treatment. METHODS Highly selective ELISAs (enzyme-linked immunosorbent assays) were used to quantify soluble Aβ40, Aβ42, and neurotoxic Aβ oligomers/protofibrils, associated with Aβ aggregation, in cortical biopsy samples obtained in patients with iNPH (n = 20), sampled during ventriculoperitoneal (VP) shunt surgery. Patients underwent pre- and postoperative (3-month) clinical assessment with a modified iNPH scale. The preoperative CSF biomarkers and the levels of soluble and insoluble Aβ species in cortical biopsy samples were analyzed for their association with a favorable outcome following the VP shunt procedure, defined as a ≥ 5-point increase in the iNPH scale. RESULTS The brain tissue levels of Aβ42 were negatively correlated with CSF Aβ42 (Spearman's r = -0.53, p < 0.05). The Aβ40, Aβ42, and Aβ oligomer/protofibril levels in cortical biopsy samples were higher in patients with insoluble cortical Aβ aggregates (p < 0.05). The preoperative CSF Aβ42 levels were similar in patients responding (n = 11) and not responding (n = 9) to VP shunt treatment at 3 months postsurgery. In contrast, the presence of cortical Aβ aggregates and high brain tissue Aβ42 levels were associated with a poor outcome following VP shunt treatment (p < 0.05). CONCLUSIONS Brain tissue measurements of soluble Aβ species are feasible. Since high Aβ42 levels in cortical biopsy samples obtained in patients with iNPH indicated a poor surgical outcome, tissue levels of Aβ species may be associated with the clinical response to shunt treatment.

    Rapid amyloid-β oligomer and protofibril accumulation in traumatic brain injury2017In: Brain Pathology, ISSN 1015-6305, E-ISSN 1750-3639Article in journal (Refereed)
    Abstract [en]

    Deposition of amyloid-β (Aβ) is central to Alzheimer's disease (AD) pathogenesis and associated with progressive neurodegeneration in traumatic brain injury (TBI). We analyzed predisposing factors for Aβ deposition including monomeric Aβ40, Aβ42 and Aβ oligomers/protofibrils, Aβ species with pronounced neurotoxic properties, following human TBI. Highly selective ELISAs were used to analyze N-terminally intact and truncated Aβ40 and Aβ42, as well as Aβ oligomers/protofibrils, in human brain tissue, surgically resected from severe TBI patients (n = 12; mean age 49.5 ± 19 years) due to life-threatening brain swelling/hemorrhage within one week post-injury. The TBI tissues were compared to post-mortem AD brains (n = 5), to post-mortem tissue of neurologically intact (NI) subjects (n = 4) and to cortical biopsies obtained at surgery for idiopathic normal pressure hydrocephalus patients (iNPH; n = 4). The levels of Aβ40 and Aβ42 were not elevated by TBI. The levels of Aβ oligomers/protofibrils in TBI were similar to those in the significantly older AD patients and increased compared to NI and iNPH controls (P < 0.05). Moreover, TBI patients carrying the AD risk genotype Apolipoprotein E epsilon3/4 (APOE ε3/4; n = 4) had increased levels of Aβ oligomers/protofibrils (P < 0.05) and of both N-terminally intact and truncated Aβ42 (P < 0.05) compared to APOE ε3/4-negative TBI patients (n = 8). Neuropathological analysis showed insoluble Aβ aggregates (commonly referred to as Aβ plaques) in three TBI patients, all of whom were APOE ε3/4 carriers. We conclude that soluble intermediary Aβ aggregates form rapidly after TBI, especially among APOE ε3/4 carriers. Further research is needed to determine whether these aggregates aggravate the clinical short- and long-term outcome in TBI.

    Minimal neuropathologic diagnosis for brain banking in the normal middle-aged and aged brain and in neurodegenerative disorders.2018In: Handbook of Clinical Neurology, ISSN 0072-9752, E-ISSN 2212-4152, Vol. 150, p. 131-141, article id B978-0-444-63639-3.00010-4Article in journal (Refereed)
    Abstract [en]

    Research on human brain diseases is currently often conducted on cell cultures and animals. Several questions however can only be addressed by studying human postmortem brain tissue. However, brain tissue obtained postmortem almost always displays pathology that is often related to the aging phenomenon. Thus, in order to be certain that the answers obtained are reliable, a systematic and thorough assessment of the brain tissue to be studied should be carried out. We are currently aware of several protein alterations that are found in middle-aged and aged brains that are obtained from neurologically unimpaired subjects. The most common alteration is hyperphosphorylation of τ, observed in both neurons and glial cells, in certain brain regions, followed by β-amyloid aggregation in the neuropil and vessel walls. Less common protein alterations are those noted for α-synuclein and Tar DNA-binding protein 43. It is noteworthy that these alterations, when found in excess, are diagnostic for various neurodegenerative diseases, such as Alzheimer disease, Pick disease, progressive supranuclear palsy, corticobasal degeneration, Parkinson disease, Lewy body dementia, and frontotemporal lobar degeneration. Since 1990, the neuropathology community has been aware that these protein alterations tend to progress in an orderly neuroanatomically defined manner and have thus designed a method to define a stage or a phase of the protein alteration. The neuropathology community has defined an initiation site, or neuroanatomic area that they presume the alteration originates from, and defined a presumed pattern of progression from the initiation site to other brain areas. Thus a reliable and reproducible description of each case regarding these alterations can be achieved. In addition to the above alterations, the brain tissue is also prone to various vascular alterations that should be registered as seen or not seen even if the significance of these alterations is still unclear.

    Neuroendocrine tumors with syndromic vasoactive intestinal polypeptide hypersecretion: a retrospective study2017In: International Journal of Endocrine Oncology, Vol. 4, no 1, p. 9-22Article in journal (Refereed)
    Abstract [en]

    Aim: Vasoactive intestinal polypeptide producing neuroendocrine tumors are rare and cause severe hormonal symptoms. Patients/methods: Eighteen patients with vasoactive intestinal polypeptide producing neuroendocrine tumors were analyzed with reviews of medical records, radiology and tumor tissue specimens. Results: Twelve patients (67%) had liver metastases at diagnosis. Chemotherapy, somatostatin analogs and interferon were given as medical therapies. Streptozocin/5-fluorouracil produced an objective response in 40% of the evaluable patients. Somatostatin analogs gave a clinical/biochemical response in eight out of nine patients. Transarterial embolization of the liver and peptide receptor radionuclide therapy was given to refractory cases. Sixteen patients died during the observation period. The median overall survival from diagnosis was 102 months. Conclusion: Systemic chemotherapy and somatostatin analogs should be given in cases of advanced disease or for hormonal symptoms.

    Congenital granular cell epulis: a case report2015In: Oral and Maxillofacial Surgery Cases, ISSN 2214-5419, Vol. 1, no 1, p. 8-11Article in journal (Refereed)
    Abstract [en]

    Congenital granular cell epulis (CGCE) is an uncommon benign lesion found in newborns. It has predominance for females with an 8:1 ratio in relation to males and is exclusively encountered in the oral cavity. The most affected oral site is located around the canine/incisor region of the maxillary alveolar ridge, where the lesion arises from the soft tissue as a solitary pedunculated mass. CGCE's histogenesis remains obscure and controversial. We present a rare case of 2 separate CGCE lesions adjacent to each other measuring 23 × 18 × 10 and 15 × 10 mm, positioned facially on the right maxillary alveolar process. The patient, a 2-day-old female newborn, did not experience any serious difficulty regarding breathing or deglutition. Complete surgical excision was the treatment of choice in this case, and the procedure was performed under both general and local anesthesia. Histologic and immunohistochemical analysis confirmed the diagnosis of CGCE. The patient showed satisfactory postoperative healing and excellent health at both the 10-day recall appointment and the 6-month follow-up.

    Refractory chronic "ITP": When platelet size matters2018In: Clinical Case Reports, E-ISSN 2050-0904, Vol. 6, no 9, p. 1779-1780Article in journal (Refereed)
    Abstract [en]

    Key Clinical Message Inherited conditions associated with thrombocytopenia should be included in the differential diagnosis of young patients with refractory immune thrombocytopenia (ITP), even in the absence of a positive family history. Early identification of such conditions is of vital importance in order to reach the right diagnosis and avoid unnecessary or even harmful medication.

    A nonsense mutation in CEP55 defines a new locus for a Meckel-like syndrome, an autosomal recessive lethal fetal ciliopathy.2017In: Clinical Genetics, ISSN 0009-9163, E-ISSN 1399-0004, Vol. 92, no 5, p. 510-516Article in journal (Refereed)
    Abstract [en]

    Mutations in genes involved in the cilium-centrosome complex are called ciliopathies. Meckel-Gruber syndrome (MKS) is a ciliopathic lethal autosomal recessive syndrome characterized by genetically and clinically heterogeneous manifestations, including renal cystic dysplasia, occipital encephalocele and polydactyly. Several genes have previously been associated with MKS and MKS-like phenotypes, but there are still genes remaining to be discovered. We have used whole exome sequencing (WES) to uncover the genetics of a suspected autosomal recessive Meckel syndrome phenotype in a family with two affected fetuses. RNA studies and histopathological analysis was performed for further delineation. WES lead to identification of a homozygous nonsense mutation c.256C>T (p.Arg86*) in CEP55 (centrosomal protein of 55 kDa) in the affected fetus. The variant has previously been identified in carriers in low frequencies, and segregated in the family. CEP55 is an important centrosomal protein required for the mid-body formation at cytokinesis. Our results expand the list of centrosomal proteins implicated in human ciliopathies and provide evidence for an essential role of CEP55 during embryogenesis and development of disease.

    Biobanking of fresh frozen tissue from clinical surgical specimens: transport logistics, sample selection, and histologic characterization.2011In: Methods in Molecular Biology, ISSN 1064-3745, E-ISSN 1940-6029, Vol. 675, p. 299-306Article in journal (Refereed)
    Abstract [en]

    Access to high-quality fresh frozen tissue is critical for translational cancer research and molecular -diagnostics. Here we describe a workflow for the collection of frozen solid tissue samples derived from fresh human patient specimens after surgery. The routines have been in operation at Uppsala University Hospital since 2001. We have integrated cryosection and histopathologic examination of each biobank sample into the biobank manual. In this way, even small, macroscopically ill-defined lesions can be -procured without a diagnostic hazard due to the removal of uncharacterized tissue from a clinical -specimen. Also, knowledge of the histomorphology of the frozen tissue sample - tumor cell content, stromal components, and presence of necrosis - is pivotal before entering a biobank case into costly molecular profiling studies.

    A Biological Signature for Breast Ductal Carcinoma In Situ to Predict Radiotherapy Benefit and Assess Recurrence Risk2018In: Clinical Cancer Research, ISSN 1078-0432, E-ISSN 1557-3265, Vol. 24, no 23, p. 5895-5901Article in journal (Refereed)
    Abstract [en]

    Purpose: Ductal carcinoma in situ (DCIS) patients and their physicians currently face challenging treatment decisions with limited information about the individual's subsequent breast cancer risk or treatment benefit. The DCI-SionRT biological signature developed in this study provides recurrence risk and predicts radiotherapy (RT) benefit for DCIS patients following breast-conserving surgery (BCS). Experimental Design: A biological signature that calculates an individualized Decision Score (DS) was developed and cross-validated in 526 DCIS patients treated with BCS = RT. The relationship was assessed between DS and 10-year risk of invasive breast cancer (IBC) or any ipsilateral breast event (IBE), including IBC or DCIS. RT benefit was evaluated by risk group and as a function of DS. Results: The DS was significantly associated with IBC and IBE risk, HR (per 5 units) of 4.2 and 3.1, respectively. For patients treated without RT, DS identified a Low Group with 10-year IBC risk of 4% (7% IBE) and an Elevated Risk Group with IBC risk of 15% (23% IBE). In analysis of DS and RT by group, the Elevated Risk Group received significant RT benefit, HR of 0.3 for IBC and IBE. In a clinicopathologically low-risk subset, DS reclassified 42% of patients into the Elevated Risk Group. In an interaction analysis of DS and RT, patients with elevated DS had significant RT benefit over baseline. Conclusions: The DS was prognostic for risk and predicted RT benefit for DCIS patients. DS identified a clinically meaningful low-risk group and a group with elevated 10-year risks that received substantial RT benefit over baseline.

    PD-L1 immunohistochemistry in clinical diagnostics of lung cancer: inter-pathologist variability is higher than assay variability2017In: Modern Pathology, ISSN 0893-3952, E-ISSN 1530-0285, Vol. 30, no 10, p. 1411-1421Article in journal (Refereed)
    Abstract [en]

    Assessment of programmed cell death ligand 1 (PD-L1) immunohistochemical staining is used for decision on treatment with programmed cell death 1 and PD-L1 checkpoint inhibitors in lung adenocarcinomas and squamous cell carcinomas. This study aimed to compare the staining properties of tumor cells between the antibody clones 28-8, 22C3, SP142, and SP263 and investigate interrater variation between pathologists to see if these stainings can be safely evaluated in the clinical setting. Using consecutive sections from a tissue microarray with tumor tissue from 55 resected lung cancer cases, staining with five PD-L1 assays (28-8 from two different vendors, 22C3, SP142, and SP263) was performed. Seven pathologists individually evaluated the percentage of positive tumor cells, scoring each sample applying cutoff levels used in clinical studies: < 1% positive tumor cells (score 0), 1-4% (score 1), 5-9% (score 2), 10-24% (score 3), 25-49% (score 4), and > 50% positive tumor cells (score 5). Pairwise analysis of antibody clones showed weighted kappa values in the range of 0.45-0.91 with the highest values for comparisons with 22C3 and 28-8 and the lowest involving SP142. Excluding SP142 resulted in kappa 0.75-0.91. Weighted kappa for interobserver variation between pathologists was 0.71-0.96. Up to 20% of the cases were differently classified as positive or negative by any pathologist compared with consensus score using >= 1% positive tumor cells as cutoff. A significantly better agreement between pathologists was seen using >= 50% as cutoff (0-5% of cases). In conclusion, the concordance between the PD-L1 antibodies 22C3, 28-8 and SP263 is relatively good when evaluating lung cancers and suggests that any one of these assays may be sufficient as basis for decision on treatment with nivolumab, pembrolizumab, and durvalumab. The scoring of the pathologist presents an intrinsic source of error that should be considered especially at low PD-L1 scores.

    Affinity Proteomics Exploration of Melanoma Identifies Proteins in Serum with Associations to T-Stage and Recurrence2017In: Translational Oncology, ISSN 1944-7124, E-ISSN 1936-5233, Vol. 10, no 3, p. 385-395Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Blood-based proteomic profiling may aid and expand our understanding of diseases and their different phenotypes. The aim of the presented study was to profile serum samples from patients with malignant melanoma using affinity proteomic assays to describe proteins in the blood stream that are associated to stage or recurrence of melanoma. MATERIAL AND METHODS: Multiplexed protein analysis was conducted using antibody suspension bead arrays. A total of 232 antibodies against 132 proteins were selected from (i) a screening with 4595 antibodies and 32 serum samples from melanoma patients and controls, (ii) antibodies used for immunohistochemistry, (iii) protein targets previously related with melanoma. The analysis was performed with 149 serum samples from patients with malignant melanoma. Antibody selectivity was then assessed by Western blot, immunocapture mass spectrometry, and epitope mapping. Lastly, indicative antibodies were applied for IHC analysis of melanoma tissues. RESULTS: Serum levels of regucalcin (RGN) and syntaxin 7 (STX7) were found to be lower in patients with both recurring tumors and a high Breslow's thickness (T-stage 3/4) compared to low thickness (T-stage 1/2) without disease recurrence. Serum levels of methylenetetrahydrofolate dehydrogenase 1-like (MTHFD1L) were instead elevated in sera of T3/4 patients with recurrence. The analysis of tissue sections with S100A6 and MTHFD1L showed positive staining in a majority of patients with melanoma, and S100A6 was significantly associated to T-stage. CONCLUSIONS: Our findings provide a starting point to further study RGN, STX7, MTHFD1L and S100A6 in serum to elucidate their involvement in melanoma progression and to assess a possible contribution to support clinical indications.

    Serotonin, ATRX, and DAXX Expression in Pituitary Adenomas: Markers in the Differential Diagnosis of Neuroendocrine Tumors of the Sellar Region.2017In: American Journal of Surgical Pathology, ISSN 0147-5185, E-ISSN 1532-0979, Vol. 41, no 9, p. 1238-1246Article in journal (Refereed)
    Abstract [en]

    Differential diagnosis based on morphology and immunohistochemistry between a clinically nonfunctioning pituitary neuroendocrine tumor (NET)/pituitary adenoma and a primary or secondary NET of nonpituitary origin in the sellar region may be difficult. Serotonin, a frequently expressed marker in the NETs, has not been systematically evaluated in pituitary NETs. Although mutations in ATRX or DAXX have been reported in a significant proportion of pancreatic NETs, the mutational status of ATRX and DAXX and their possible pathogenetic role in pituitary NETs are unknown. Facing a difficult diagnostic case of an invasive serotonin and adrenocorticotroph hormone immunoreactive NET in the sellar region, we explored the immunohistochemical expression of serotonin, ATRX, and DAXX in a large series of pituitary endocrine tumors of different types from 246 patients and in 2 corticotroph carcinomas. None of the pituitary tumors expressed serotonin, suggesting that serotonin immunoreactive sellar tumors represent primary or secondary NETs of nonpituitary origin. Normal expression of ATRX and DAXX in pituitary tumors suggests that ATRX and DAXX do not play a role in the pathogenesis of pituitary endocrine tumors that remain localized to the sellar and perisellar region. A lack of ATRX or DAXX in a sellar NET suggests a nonpituitary NET, probably of pancreatic origin. One of the 2 examined corticotroph carcinomas, however, demonstrated negative ATRX immunolabeling due to an ATRX gene mutation. Further studies on a larger cohort of pituitary carcinomas are needed to clarify whether ATRX mutations may contribute to the metastatic potential in a subset of pituitary NETs.

    Pharmacological targeting of peptidylarginine deiminase 4 prevents cancer-associated kidney injury in mice.2017In: Oncoimmunology, ISSN 2162-4011, E-ISSN 2162-402X, Vol. 6, no 8, article id e1320009Article in journal (Refereed)
    Abstract [en]

    Renal insufficiency is a frequent cancer-associated problem affecting more than half of all cancer patients at the time of diagnosis. To minimize nephrotoxic effects the dosage of anticancer drugs are reduced in these patients, leading to sub-optimal treatment efficacy. Despite the severity of this cancer-associated pathology, the molecular mechanisms, as well as therapeutic options, are still largely lacking. We here show that formation of intravascular tumor-induced neutrophil extracellular traps (NETs) is a cause of kidney injury in tumor-bearing mice. Analysis of clinical biomarkers for kidney function revealed impaired creatinine clearance and elevated total protein levels in urine from tumor-bearing mice. Electron microscopy analysis of the kidneys from mice with cancer showed reversible pathological signs such as mesangial hypercellularity, while permanent damage such as fibrosis or necrosis was not observed. Removal of NETs by treatment with DNase I, or pharmacological inhibition of the enzyme peptidylarginine deiminase 4 (PAD4), was sufficient to restore renal function in mice with cancer. Tumor-induced systemic inflammation and impaired perfusion of peripheral vessels could be reverted by the PAD4 inhibitor. In conclusion, the current study identifies NETosis as a previously unknown cause of cancer-associated renal dysfunction and describes a novel promising approach to prevent renal failure in individuals with cancer.

    Human hematopoietic progenitors are generally assumed to require stem cell factor (SCF) and KIT signaling during differentiation for the formation of mast cells. Imatinib treatment, which inhibits KIT signaling, depletes mast cells in vivo. Furthermore, the absence of SCF or imatinib treatment prevents progenitors from developing into mast cells in vitro. However, these observations do not mean that mast cell progenitors require SCF and KIT signaling throughout differentiation. Here, we demonstrate that circulating mast cell progenitors are present in patients undergoing imatinib treatment. In addition, we show that mast cell progenitors from peripheral blood survive, mature, and proliferate without SCF and KIT signaling in vitro. Contrary to the prevailing consensus, our results show that SCF and KIT signaling are dispensable for early mast cell development.

    Detection of autoantibodies against cancer-testis antigens in non-small cell lung cancer2018In: Lung Cancer, ISSN 0169-5002, E-ISSN 1872-8332, Vol. 125, p. 157-163Article in journal (Refereed)
    Abstract [en]

    Cancer testis antigens (CTAs) are defined as proteins that are specifically expressed in testis or placenta and their expression is frequently activated in cancer. Due to their ability to induce an immune response, CTAs may serve as suitable targets for immunotherapy. The aim of this study was to evaluate if there is reactivity against CTAs in the plasma of non-small cell lung cancer (NSCLC) patients through the detection of circulating antibodies. 

    To comprehensively analyse auto-antibodies against CTAs the multiplexing capacities of suspension bead array technology was used. Bead arrays were created with 120 protein fragments, representing 112 CTAs. Reactivity profiles were measured in plasma samples from 133 NSCLC patients and 57 cases with benign lung diseases. Altogether reactivity against 69 antigens, representing 81 CTAs, was demonstrated in at least one of the analysed samples. Twenty-nine of the antigens (45 CTAs) demonstrated exclusive reactivity in NSCLC samples. Reactivity against CT47A genes, PAGE3, VCX, MAGEB1, LIN28B and C12orf54 were only found in NSCLC patients at a frequency of 1%-4%. The presence of autoantibodies towards these six antigens was confirmed in an independent group of 34 NSCLC patients.

    In conclusion, we identified autoantibodies against CTAs in the plasma of lung cancer patients. The reactivity pattern of autoantibodies was higher in cancer patients compared to the benign group, stable over time, but low in frequency of occurrence. The findings suggest that some CTAs are immunogenic and that these properties can be utilized as immune targets.

    Gene-specific correlation of RNA and protein levels in human cells and tissues2016In: Molecular Systems Biology, ISSN 1744-4292, E-ISSN 1744-4292, Vol. 12, no 10, article id 883Article in journal (Refereed)
    Abstract [en]

    An important issue for molecular biology is to establish whether transcript levels of a given gene can be used as proxies for the corresponding protein levels. Here, we have developed a targeted proteomics approach for a set of human non-secreted proteins based on parallel reaction monitoring to measure, at steady-state conditions, absolute protein copy numbers across human tissues and cell lines and compared these levels with the corresponding mRNA levels using transcriptomics. The study shows that the transcript and protein levels do not correlate well unless a gene-specific RNA-to-protein (RTP) conversion factor independent of the tissue type is introduced, thus significantly enhancing the predictability of protein copy numbers from RNA levels. The results show that the RTP ratio varies significantly with a few hundred copies per mRNA molecule for some genes to several hundred thousands of protein copies per mRNA molecule for others. In conclusion, our data suggest that transcriptome analysis can be used as a tool to predict the protein copy numbers per cell, thus forming an attractive link between the field of genomics and proteomics.

    Glioneuronal tumors in childhood - Before and after surgery. A long-term follow-up study2017In: Epilepsy & Behavior, ISSN 1525-5050, E-ISSN 1525-5069, Vol. 72, p. 82-88Article in journal (Refereed)
    Abstract [en]

    Aim: To give a detailed description of the long-term outcome of a cohort of children with glioneuronal tumors regarding pre-and postsurgical factors, including "dual" and "double" pathology, seizure freedom, and psychosocial outcome.

    Methods: During a fifteen-year period (1995-2009), all patients (age 0-17.99 years) with a glioneuronal brain tumor diagnosed and treated at Uppsala University Children's Hospital were identified from the National Brain Tumor Registry and the National Epilepsy Surgery Registry. Hospital medical records were reviewed and neuroradiological and neuropathological findings were re-evaluated. A cross-sectional long-term follow-up prospective evaluation, including an interview, neurologic examination, and electroencephalogram, was accomplished in patients accepting participants in the study.

    Results: A total of 25 out of 28 (89%) eligible patientswere included. The M: F ratiowas 1.5: 1. Mean follow-up time after surgery was 12.1 years (range 5.0-19.3). Twenty patients were adults (N18 years) at follow-up. Seizure freedomwas achieved in 64%. Gross total resection (GTR) was the only preoperative factor significantly correlating to seizure freedom (p= 0.027). Thirty-eight percent were at some time postoperatively admitted for a psychiatric evaluation. There was a trend towards both higher educational level and employment status in adults who became seizure free.

    Conclusion: Long-termoutcome is good regarding seizure freedom if GTR can be achieved, but late seizure recurrence can occur. "Dual" and "double" pathology is uncommon and does not influence seizure outcome. Obtaining seizure freedomseems to be important for psychosocial outcome, but there is a risk for psychiatric comorbidities and long-term follow-up by a multi-professional team is advisable.

    A Phase I/IIa Trial Using CD19-Targeted Third-Generation CAR T Cells for Lymphoma and Leukemia2018In: Clinical Cancer Research, ISSN 1078-0432, E-ISSN 1557-3265, Vol. 24, no 24, p. 6185-6194Article in journal (Refereed)
    Abstract [en]

    Purpose: The chimeric antigen receptor (CAR) T-cell therapy has been effective for patients with CD19(+) B-cell malignancies. Most studies have investigated the second-generation CARs with either CD28 or 4-1BB costimulatory domains in the CAR receptor. Here, we describe the first clinical phase I/IIa trial using third-generation CAR T cells targeting CD19 to evaluate safety and efficacy.

    Patients and Methods: Fifteen patients with B-cell lymphoma or leukemia were treated with CAR T cells. The patients with lymphoma received chemotherapy during CAR manufacture and 11 of 15 were given low-dose cyclophosphamide and fludarabine conditioning prior to CAR infusion. Peripheral blood was sampled before and at multiple time points after CAR infusion to evaluate the persistence of CAR T cells and for immune profiling, using quantitative PCR, flow cytometry, and a proteomic array.

    Results: Treatment with third-generation CAR T cells was generally safe with 4 patients requiring hospitalization due to adverse reactions. Six of the 15 patients had initial complete responses [4/11 lymphoma and 2/4 acute lymphoblastic leukemia (ALL)], and 3 of the patients with lymphoma were in remission at 3 months. Two patients are still alive. Best predictor of response was a good immune status prior to CAR infusion with high IL12, DC-Lamp, Fas ligand, and TRAIL. Responding patients had low monocytic myeloid-derived suppressor cells (MDSCs; CD14(+)CD33(+)HLA(-)DR(-)) and low levels of IL6, IL8, NAP3, sPDL1, and sPDL2.

    Conclusions: Third-generation CARs may be efficient in patients with advanced B-cell lymphoproliferative malignancy with only modest toxicity. Immune profiling pre- and posttreatment can be used to find response biomarkers.

    Diffusion kurtosis imaging of gliomas grades II and III: a study of perilesional tumor infiltration, tumor grades and subtypes at clinical presentation2017In: Radiology and Oncology, ISSN 1318-2099, E-ISSN 1581-3207, Vol. 51, no 2, p. 121-129Article in journal (Refereed)
    Abstract [en]

    Background. Diffusion kurtosis imaging (DKI) allows for assessment of diffusion influenced by microcellular structures. We analyzed DKI in suspected low-grade gliomas prior to histopathological diagnosis. The aim was to investigate if diffusion parameters in the perilesional normal-appearing white matter (NAWM) differed from contralesional white matter, and to investigate differences between glioma malignancy grades II and III and glioma subtypes (astrocytomas and oligodendrogliomas).

    Patients and methods. Forty-eight patients with suspected low-grade glioma were prospectively recruited to this institutional review board-approved study and investigated with preoperative DKI at 3T after written informed consent. Patients with histologically proven glioma grades II or III were further analyzed (n=35). Regions of interest (ROIs) were delineated on T2FLAIR images and co-registered to diffusion MRI parameter maps. Mean DKI data were compared between perilesional and contralesional NAWM (student's t-test for dependent samples, Wilcoxon matched pairs test). Histogram DKI data were compared between glioma types and glioma grades (multiple comparisons of mean ranks for all groups). The discriminating potential for DKI in assessing glioma type and grade was assessed with receiver operating characteristics (ROC) curves.

    Results. There were significant differences in all mean DKI variables between perilesional and contralesional NAWM (p=< 0.000), except for axial kurtosis (p=0.099). Forty-four histogram variables differed significantly between glioma grades II (n=23) and III (n=12) (p=0.003-0.048) and 10 variables differed significantly between ACs (n=18) and ODs (n=17) (p=0.011-0.050). ROC curves of the best discriminating variables had an area under the curve (AUC) of 0.657-0.815.

    Conclusions. Mean DKI variables in perilesional NAWM differ significantly from contralesional NAWM, suggesting altered microstructure by tumor infiltration not depicted on morphological MRI. Histogram analysis of DKI data identifies differences between glioma grades and subtypes.

    Therapeutic vaccination against fibronectin ED-A attenuates progression of metastatic breast cancer.2014In: OncoTarget, ISSN 1949-2553, E-ISSN 1949-2553, Vol. 5, no 23, p. 12418-12427Article in journal (Refereed)
    Abstract [en]

    Therapeutic vaccination targeting self-molecules is an attractive alternative to monoclonal antibody-based therapies for cancer and various inflammatory diseases. However, development of cancer vaccines targeting self-molecules has proven difficult. One complicating factor is that tumor cells have developed strategies to escape recognition by the immune system. Antigens specifically expressed by the tumor vasculature can therefore provide alternative targets. The alternatively spliced extra domain-A and B (ED-A and ED-B) of fibronectin are expressed during vasculogenesis in the embryo, but essentially undetectable under normal conditions in the adult. However, these domains are re-expressed during tumor angiogenesis and matrix remodeling, which renders them highly interesting for targeted cancer therapies. Using the MMTV-PyMT transgenic model of metastatic mammary carcinoma, we show that tumor burden can be significantly decreased by immunization against ED-A in a therapeutic setting. Furthermore, we found that in mice carrying anti-ED-A antibodies the number of metastases was reduced. ED-A immunization increased infiltration of macrophages and compromised tumor blood vessel function. These findings implicate an attack of the tumor vasculature by the immune system, through a polyclonal antibody response. We conclude that tumor vascular antigens are promising candidates for development of therapeutic vaccines targeting growth of primary tumors as well as disseminated disease.

    Signatures of post-zygotic structural genetic aberrations in the cells of histologically normal breast tissue that can predispose to sporadic breast cancer2015In: Genome Research, ISSN 1088-9051, E-ISSN 1549-5469, Vol. 25, no 10, p. 1521-1535Article in journal (Refereed)
    Abstract [en]

    Sporadic breast cancer (SBC) is a common disease without robust means of early risk prediction in the population. We studied 282 females with SBC, focusing on copy number aberrations in cancer-free breast tissue (uninvolved margin, UM) outside the primary tumor (PT). In total, 1162 UMs (1-14 per breast) were studied. Comparative analysis between UM(s), PT(s), and blood/skin from the same patient as a control is the core of the study design. We identified 108 patients with at least one aberrant UM, representing 38.3% of cases. Gains in gene copy number were the principal type of mutations in microscopically normal breast cells, suggesting that oncogenic activation of genes via increased gene copy number is a predominant mechanism for initiation of SBC pathogenesis. The gain of ERBB2, with overexpression of HER2 protein, was the most common aberration in normal cells. Five additional growth factor receptor genes (EGFR, FGFR1, IGF1R, LIFR, and NGFR) also showed recurrent gains, and these were occasionally present in combination with the gain of ERBB2. All the aberrations found in the normal breast cells were previously described in cancer literature, suggesting their causative, driving role in pathogenesis of SBC. We demonstrate that analysis of normal cells from cancer patients leads to identification of signatures that may increase risk of SBC and our results could influence the choice of surgical intervention to remove all predisposing cells. Early detection of copy number gains suggesting a predisposition toward cancer development, long before detectable tumors are formed, is a key to the anticipated shift into a preventive paradigm of personalized medicine for breast cancer.

    Breast cancer in young women and prognosis: How important are proliferation markers?2017In: European Journal of Cancer, ISSN 0959-8049, E-ISSN 1879-0852, Vol. 84, p. 278-289Article in journal (Refereed)
    Abstract [en]

    Aim:

    Compared to middle-aged women, young women with breast cancer have a higher risk of systemic disease. We studied expression of proliferation markers in relation to age and subtype and their association with long-term prognosis.

    Methods:

    Distant disease-free survival (DDFS) was studied in 504 women aged <40 years and 383 women aged >= 40 years from a population-based cohort. Information on patient characteristics, treatment and follow-up was collected from medical records. Tissue microarrays were produced for analysis of oestrogen receptor, progesterone receptor (PR), Her2, Ki-67 and cyclins.

    Results:

    Young women with luminal tumours had significantly higher expression of Ki-67 and cyclins. Proliferation markers were prognostic only within this subtype. Ki-67 was a prognostic indicator only in young women with luminal PR+ tumours. The optimal cut-off for Ki-67 varied by age. High expression of cyclin E1 conferred a better DDFS in women aged <40 years with luminal PR- tumours (hazard ratio [HR] 0.47 [0.24-0.92]). Age < 40 years was an independent risk factor of DDFS exclusively in women with luminal B PR+ tumours (HR 2.35 [1.22-4.50]). Young women with luminal B PR- tumours expressing low cyclin E1 had a six-fold risk of distant disease compared with luminal A ( HR 6.21 [2.17-17.6]).

    Conclusions:

    The higher expression of proliferation markers in young women does not have a strong impact on prognosis. Ki-67 is only prognostic in the subgroup of young women with luminal PR tumours. The only cyclin adding prognostic value beyond subtype is cyclin E1. Age is an independent prognostic factor only in women with luminal B PR+ tumours.

    High tumour plasma cell infiltration reflects an important microenvironmental component in classic Hodgkin lymphoma linked to presence of B-symptoms2019In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 184, no 2, p. 192-201Article in journal (Refereed)
    Abstract [en]

    Plasma cells are important prognostic actors in different malignancies. The tumour microenvironmental composition in classic Hodgkin lymphoma (cHL) is a major prognostic key element; however, clinicopathological studies regarding plasma cells in cHL are lacking. The aim of this study was to investigate CD138+ (also termed SDC1+) plasma cell and IgG4 producing (IgG4+) plasma cells infiltration in the microenvironment of cHL. Immunohistochemistry with anti-CD138 and IgG4 antibodies was performed on diagnostic tumour biopsies from 124 patients with cHL, on tissue micro array (TMA). In 120 cases, CD138+ plasma cell-infiltration was associated with the presence of B-symptoms (P = 0·028) and advanced stage, IIB-IVB (P = 0·009). In multivariate analysis, CD138+ plasma cells correlated with eosinophil infiltration (P = 0·013). The subgroup of IgG4+ plasma cells was analysed in 122 cases and only correlated to CD138+ plasma cells (P = 0·004). Patients with high proportion of tumour infiltrating CD138+ plasma cells (defined as ≥10%), had a more inferior event-free survival (P = 0·007) and overall survival (P = 0·004) than patients with a low proportion of infiltrating CD138+ plasma cells (<10%), although significance was not maintained in multivariate analysis. In summary, a high proportion of tumour-associated plasma cells in cHL reflect an important component in the microenvironment of cHL.
