Özet

Aim: The aim of this study is to evaluate the prognostic value of beta-catenin and LEF-1 expression in patients with operable gastric cancer that receive adjuvant treatment and the relationship between demographic and histopathological variables. Material and method: In this study, 82 gastric cancer patients treated with adjuvant treatment after surgery and followed in the Medical Oncology Department of Kocaeli University were included. beta-catenin and LEF-1 expression were examined by immunuhistochemical analysis in paraffin embedded tumor tissues of the patients. Results: Median age was 56 (26-81) and follow up was 19 months (4-61). Performance status (ECOG) were 0-1 in all patients. Male/female ratio was 53/29 (64.6/35.4%). The median disease free survival (DFS) time was 17 months (SE: 3 95% CI: 11-23) and 3 years DFS rate was 39.7%. The median overall survival (OS) time was 28 months (SE: 4 95% CI: 20-36) and 3 years OS rate was 41.2%. There was no statistical correlation between beta-catenin and LEF-1 expression and age, gender, performance status, tumor localization, T and N stage, lymphovascular, perinoral invasion, grade and operation type (>0.005). According to univariate analysis, we did not find significant effect of age, gender, T stage, lymphovascular, perinoral invasion, grade and operation type on overall survival (p>0.005). Good performance status (ECOG 0), tumor infiltration without diffuse type like linitis plastica, and lower N stage had positive effect on survival respectively (p=0.04, 0.033 and 0.005). Conclusion: In this study group, we found that only N stage was an independent prognostic factor (<0.005). Demographic features of the patients, histopathological characteristics other than N stage, beta-catenin and LEF-1 prognostic effects have not been shown.
