Survival of patients with ovarian epithelial carcinomas after second-look laparotomy

Survival of ovarian carcinoma patients undergoing second-look laparotomy after primary surgery and adjunctive chemotherapy was evaluated by retrospective chart review. From August 1976 to August 1987, 102 patients with stage I-IV disease underwent second-look laparotomy. Optimal tumor debulking and early (stage I or II) disease were positively correlated with a negative second-look laparotomy. Of the 49 patients with a "negative" second look, 15 demonstrated recurrent tumor from 12.5 to 52.5 months after laparotomy. Of the 15 recurrences, 6 were documented more than 3 years following second look. Half of the 28 patients with stage III disease and a "negative" second look have demonstrated recurrent tumor. Fifty-three patients (52%) were found to have residual disease at second-look laparotomy. Initial chemotherapy (melphalan or multiple agent) and the adequacy of primary debulking surgery (optimal vs suboptimal) were not significant factors contributing to patient survival after a positive second look. However, the size of residual disease at second-look laparotomy was a significant factor in subsequent patient survival (P ≤ 0.01). Fifteen patients were free of gross disease at laparotomy, but had residual tumor on microscopic examination of the specimens submitted. These patients had a 2-year actuarial survival of 78%. Forty-seven percent have survived 5 or more years after second look. Nineteen patients with tumor implants 2 cm or smaller had 2- and 5-year actuarial survivals of 61 and 31%, respectively. Nineteen patients with tumor nodules larger than 2 cm in diameter had a 2-year actuarial survival of 6%. Only 1 of 19 patients with nodules greater than 2 cm could be effectively redebulked.
