Abstract
In ovarian cancer stages IIB-IV, pre-treatment variables and variables obtained intraoperatively at second-look laparotomy were investigated for their prognostic influence on the outcome of 109 patients and survival after second-look laparotomy in 131 patients. The subjects came from a randomized trial of sequential versus alternating combination chemotherapy. The overall median survival after second-look laparotomy was 62 months. Logistic regression analysis identified stage and hysterectomy plus bilateral salpingo-oophorectomy and omentectomy as significant prognostic covariates for second-look laparotomy outcome. Based on a Cox multivariate stepwise analysis, independent prognostic factors for survival after second-look laparotomy were secondary residual tumor size, pre-treatment histologic differentiation grade, and performance status. A high differentiation grade and a good performance status at the start of therapy thus still had a prolonging effect on survival after second-look laparotomy. The prognostic power of these pre-treatment variables was increased substantially by the addition of the secondary residual tumor size variable. The 3-year survival rate after second-look laparotomy for high-and low-risk patients was 15 and 87%, respectively. Second-look laparotomy thus provides prognostic information in patients with advanced ovarian carcinoma, but the benefit in terms of survival is still unclear.
