Abstract [en]

Aim: Inhibition of cyclooxygenase-2 (COX-2) is proposed as a treatment option in several cancer types. However, in non-small cell lung cancer (NSCLC), phase III trials have failed to demonstrate a benefit of adding COX-2 inhibitors to standard chemotherapy. The aim of this study was to analyze COX-2 expression in tumor and stromal cells as predictive biomarker for COX-2 inhibition.

Methods: In a multicenter phase III trial, 316 patients with advanced NSCLC were randomized to receive celecoxib (400 mg b.i.d.) or placebo up to one year in addition to a two-drug platinum-based chemotherapy combination. In a subset of 122 patients, archived tumor tissue was available for immunohistochemical analysis of COX-2 expression in tumor and stromal cells. For each compartment, COX-2 expression was graded as high or low, based on a product score of extension and intensity of positively stained cells.

Results: An updated analysis of all 316 patients included in the original trial, and of the 122 patients with available tumor tissue, showed no survival differences between the celecoxib and placebo arms (HR 1.01; 95% CI 0.81–1.27 and HR 1.12; 95% CI 0.78–1.61, respectively). High COX-2 scores in tumor (n = 71) or stromal cells (n = 55) was not associated with a superior survival outcome with celecoxib vs. placebo (HR =0.96, 95% CI 0.60–1.54; and HR =1.51; 95% CI 0.86–2.66), and no significant interaction effect between COX-2 score in tumor or stromal cells and celecoxib effect on survival was detected (p = .48 and .25, respectively).

Conclusions: In this subgroup analysis of patients with advanced NSCLC treated within the context of a randomized trial, we could not detect any interaction effect of COX-2 expression in tumor or stromal cells and the outcome of celecoxib treatment in addition to standard chemotherapy.

Abstract [en]

BACKGROUND: Patients treated for hematological malignancies have an increased risk of serious infections. Diagnosis and prompt initiation of therapy are essential. Bronchoalveolar lavage (BAL) is a well-established investigation for identifying the cause of pulmonary infiltrates in immunocompromised patients. The aim of the study was to determine the diagnostic yield of BAL in patients treated for hematological malignancies and how often it contributed to a modification of the anti-infectious therapy.

METHODS: We reviewed records from 151 consecutive BAL procedures in 133 adult patients with hematological malignancies, treated at a tertiary hematology unit from 2004 to 2013. Extensive microbiological work-ups on BAL samples had been performed according to a standardized protocol.

RESULTS: A microbiological finding causing the infectious episode could be identified in 59 (39%) cases. In 44 (29%) of the cases, results from BAL had an impact on clinical management either by contributing to a specific diagnosis (25%) or by leading to cessation of ongoing microbiological therapy. The most common diagnoses were invasive pulmonary aspergillosis (IPA) and Pneumocystis jirovecii pneumonia (PJP). Diagnoses of IPA and PJP were based on results from BAL in 65% and 93% of cases, respectively. Several microbiological tests on BAL samples rendered no positive results. Complications were few and mainly mild.

CONCLUSION: BAL is still important for either verifying or excluding some of the most important respiratory tract pathogens in patients with hematological malignancies, particularly IPA and PJP. Standardized procedures for BAL sampling should be continually revised to exclude unnecessary microbiological tests.

Abstract [en]

AXL1717 is an orally bioavailable IGF-1R pathway modulator that has been shown to have anti-tumoral effects. The objectives of the present study were to define maximum tolerated dose and the recommended phase II dose (RPTD) of AXL1717 in combination with gemcitabine HCl and carboplatin in non-small cell lung cancer (NSCLC). Patients with previously untreated, locally advanced, or metastatic NSCLC (squamous cell cancer or adenocarcinoma) in good performance status and with preserved major organ functions were enrolled in the study. The study was an open-label phase I study with planned cohorts of three patients per dose level of AXL1717 (215, 290, and 390 mg BID). In total, 12 patients were enrolled in the study, and of these, two were prematurely excluded. AXL1717 was administered at one dose level, 215 mg BID. A total number of 81 unique adverse events were reported. Bone marrow toxicity was reported in 10 out of 12 patients, and this organ class showed the largest number of related events. AXL1717 in combination with gemcitabine HCl and carboplatin is a possible treatment approach in previously untreated, locally advanced, or metastatic non-small cell lung cancer. However, due to the bone marrow toxicity profile shown in the present study, further dose increases of AXL1717 above 215 mg BID will probably not be feasible. Therefore, 215 mg BID constitutes maximum tolerated dose and RPTD.

Abstract [en]

Aim of the study:

The primary purpose of this study is to investigate if pretreatment plasma levels of vascular endothelial growth factor (VEGF) are predictive of the effect of celecoxib on survival in advanced non-small cell lung cancer (NSCLC) treated with palliative chemotherapy. A secondary objective is to describe the course of plasma VEGF levels during and after treatment with cytotoxic chemotherapy combined with celecoxib or placebo.

Methods:

In a previously published double-blind multicenter phase III trial, 316 patients with NSCLC stage IIIB or IV and World Health Organisation (WHO) performance status 0-2 were randomised to receive celecoxib 400 mg b.i.d. or placebo in combination with two-drug platinum-based chemotherapy. Chemotherapy cycle length was three weeks and planned duration of chemotherapy was four cycles. Celecoxib was given for a maximum of one year but was stopped earlier in case of disease progression or prohibitive toxicity. In a subset of patients, plasma VEGF levels were examined at onset of treatment and at 6, 12 and 20 weeks.

Results:

VEGF levels at start of treatment were obtained in 107 patients at four study sites. The median value was 70 pg/ml. Mean values declined during the first 12 weeks and then increased at 20 weeks. A subpopulation treatment effect pattern plot (STEPP) analysis showed an inverse relationship between initial plasma VEGF and the impact of celecoxib on survival with zero effect at 200 pg/ml. The effect on survival by celecoxib in the whole subset of patients was positive (hazard ratio (HR) = 0.64 [confidence interval (CI) 0.43-0.95], p = 0.028).

Conclusion:

Low pretreatment plasma levels of VEGF appear to be predictive of a positive effect of celecoxib on survival.

Abstract [en]

The complex interaction between cancer cells and the microenvironment plays an essential role in all stages of tumourigenesis. Despite the significance of this interplay, alterations in protein composition underlying tumour-stroma interactions are largely unknown. The aim of this study was to identify stromal proteins with clinical relevance in non-small cell lung cancer (NSCLC). A list encompassing 203 stromal candidate genes was compiled based on gene expression array data and available literature. The protein expression of these genes in human NSCLC was screened using the Human Protein Atlas. Twelve proteins were selected that showed a differential stromal staining pattern (BGN, CD99, DCN, EMILIN1, FBN1, PDGFRB, PDLIM5, POSTN, SPARC, TAGLN, TNC, VCAN). The corresponding antibodies were applied on tissue microarrays, including 190 NSCLC samples, and stromal staining was correlated with clinical parameters. Higher stromal expression of CD99 was associated with better prognosis in the univariate (p=0.037) and multivariate (p=0.039) analysis. The association was independent from the proportion of tumour stroma, the fraction of inflammatory cells, and clinical and pathological parameters like stage, performance status and tumour histology. The prognostic impact of stromal CD99 protein expression was confirmed in an independent cohort of 240 NSCLC patients (p=0.008). Furthermore, double-staining confocal fluorescence microscopy showed that CD99 was expressed in stromal lymphocytes as well as in cancer associated fibroblasts. Based on a comprehensive screening strategy the membrane protein CD99 was identified as a novel stromal factor with clinical relevance. The results support the concept that stromal properties have an important impact on tumour progression.

Abstract [en]

There is a need to improve the prognostic and predictive indicators in non-small cell lung cancer (NSCLC). At present, the main focus is on genetic predictive markers while the prognostic value of the standard blood variables related to haematopoiesis has been subjected to relatively limited attention. To study the prognostic potential of haemoglobin (Hgb), platelet (Plt) and white blood cell (WBC) levels at time of diagnosis in NSCLC patients, 835 NSCLC patients, stage I-IV, who received radiotherapy with curative intention (> 50 Gy), were included in the study. WBC, Plt, Hgb, gender, age at diagnosis, stage, surgery and first-line chemotherapy were studied in relation to overall survival. For patients with Hgb < 110 g/L and Hgb a parts per thousand yen 110 g/L), the median survival was 11.2 and 14.5 months, respectively (p = 0.0032). For WBC > 9.0 x 10(9)/L and < 9.0 x 10(9)/L, the median survival was 11.6 and 15.4 months, respectively (p < 0.0001). For Plt > 350 x 10(9)/L and < 350 x 10(9)/L, the median survival was 11.2 and 14.9 months, respectively (p < 0.0001). The median survival in patients with pathological results in all three markers was half of that in patients with normal levels of all three markers (8.0 and 16.0 months, respectively (p < 0.0001). The level of the three studied haematological biomarkers corresponds significantly to outcome in NSCLC. These results indicate that standard haematological variables may be used as guidance for the clinician in the decision-making regarding treatment intensity and patient information.
