“…According to the consensus of the NIH (National Institute of Health), patients with UICC stage I rectal cancer (pT1/2, pN0) are not enrolled to adjuvant radiochemotherapy, whereas patients with UICC stage II rectal cancer (pT3/4, pN0) undergo adjuvant radiochemotherapy [20]. However, reflecting our collective, 24.2% (8/33) of UICC stage II develop distant metastases (without local recurrence) after curative resection, which means that -from the theoretical aspectradiochemotherapy means 'over-therapy' in 75.8% of patients; this is also explained by other authors [21]. Consequently, identification of prognostic factors to predict individual outcome, to select appropriate adjuvant treatment and follow-up options, and, finally, to analyze and compare treatment results is a crucial issue [22].…”

The aim of this study was to evaluate the prognostic role of clinical and histopathologic factors, cell-cycle regulator proteins (p21^Waf1/Cip1, p27^Kip1), and apoptotic index in lymph node-negative rectal cancer. Formalin-fixed, paraffin-embedded tissue samples of 97 rectal carcinomas (UICC stages I and II) resected curatively within five years were used. Immunohistochemical analysis of protein expression was performed by monoclonal antibodies: p21 (clone SX118), p27 (clone SX53G8). Apoptosis was assessed by the TUNEL method. Clinical, surgical, histopathologic, and follow-up data were prospectively recorded in a computerized registry. To assess prognostic significance (end points: metachronous distant metastases, 5-year disease-free and overall survival), statistics included univariate and multivariate analysis (p < 0.05 statistically significant). Of the 97 rectal carcinomas without lymph node metastases, 46.4% (45/97) were p21-positive, 49.5% were p27-positive (48/97), whereas 27.8% (27/97) showed a high apoptotic index. Within a median follow-up of 54 months, 4 patients developed local recurrence (4.1%). Distant metastases occurred in 12 patients (12.4%). Univariate analysis showed that gender, UICC stage, p21 and p27 were significantly associated with the incidence of distant metastases (p < 0.05). UICC stage and p21 were the only factors to be significantly related to 5-year disease-free survival by univariate analysis (p < 0.05). Only UICC stage was significantly related to 5-year overall survival (p < 0.05). The apoptotic index was correlated neither to recurrence nor to survival (p > 0.05). Multivariate analysis demonstrated that gender, UICC stage and p21 were independently related to the incidence of distant metastases; however, UICC stage was the only independent factor predictive of 5-year disease-free survival and overall survival (p < 0.05).

Angiogenese und Dichte dendritischer Zellen korrelieren nicht mit der metachronen Fernmetastasierung beim kurativ operierten Rectumcarcinom

Abstract: Angiogenesis and density of dendritic cells in rectal cancer are not prognostic factors for metachronous distant metastasis and, therefore, cannot serve as selection parameters for adjuvant therapy.
