Abstract [en]

Aim Predictive tools for local recurrence (LR) of rectal cancer are needed. This study assessed the predictive value of tumour budding detected by MNF-116 and laminin-5 gamma 2 chain (Ln-5 gamma 2). Method In a case-control study, the surgical specimens of 48 patients with LR after from primary resection of rectal carcinoma and 82 control patients matched for gender and preoperative radiation from a population of 1180 patients operated with total mesorectal excison were studied. The presence of budding was examined using immunohistochemistry with Ln-5 gamma 2 and pancytokeratin staining with MNF-116. Results Tumour budding counts ranged from 0 to 106 buds (mean 43, median 38) for all patients. Significantly more tumours with more than 35 buds were seen in the LR than in the control group (67 vs 44%; P = 0.02). The spread of budding was also more extensive in the LR than in the control group (63 vs 49%, P = 0.03). In a multivariate analysis with tumour, node, metastasis stage, MNF-116-stained budding was an independent predictor of local failure (P = 0.02). The budding frequency was higher in irradiated tumours in comparison with tumours that had not received irradiation (mean 53 vs 38, P = 0.03). For Ln-5 gamma 2, more tumours with 10 buds were seen in the group with LR than among the control patients, but this difference was not statistically significant (73 vs 57%; P = 0.09). No additive value was found in the multivariate logistic regression model when Ln-5 gamma 2-stained budding frequency was added to MNF-116 and tumour, node, metastasis stage. The agreement between budding frequency determined by MNF-116 and Ln-5 gamma 2 was moderate, with a kappa-coefficient of 0.34 (0.16-0.51). Conclusion Tumour budding determined by MNF-116 staining may serve as a predictive marker for LR in rectal cancer.
