Popis: | Purpose: The aim of this study was to assess the prognostic relevance of apoptotic index (AI), considered alone or together with expression of several proteins controlling G1 check point (p53, mdm2, pRb and p21WAF1/CIP1) in non-small cell lung cancer (NSCLC) patients. Methods: Study group included 50 NSCLC patients who underwent curative pulmonary resection. Apoptosis was detected with the use of TUNEL technique and AI was defined as the number of apoptotic cells per 1,000 tumor cells. The expression of p53, mdm2, pRb and p21WAF1/CIP1 was assessed immunohistochemically. Results: The mean and median AI calculated for all 50 patients was 14 and 9, respectively. Patients with lower ( |
