Primary chemotherapy and adjuvant tumor debulking in the management of advanced-stage epithelial ovarian cancer.

The aim of this article was to review the experience with neoadjuvant chemotherapy and interval surgical debulking in patients with metastatic epithelial ovarian cancer. A retrospective chart review was carried out to identify patients treated with neoadjuvant platinum/Taxol chemotherapy and interval debulking. Cox regression modeling was used to identify significant predictors of progression-free interval. The Kaplan-Meier method was used to estimate the survival statistic for the study group. Sixty-one patients were identified after being treated with neoadjuvant chemotherapy and interval debulking surgeries. All surgeries were performed after three cycles of platinum/Taxol combination chemotherapy. Eighty percent of patients had a residual disease status of 2 cm or less after surgery. Suboptimal debulking was statistically associated with tumor involvement of the upper abdominal organs (P < 0.001) and non-normalization of CA125 before surgery (P= 0.03). The perioperative complication rate was 7%. At a mean follow-up time of 19 months, 77% of patients were still alive. Cox regression modeling identified the microscopic tumor residual status as the only significant predictor of progression-free interval. The estimated median survival for the group was 41.70 months (95% confidence interval = 13.84-69.56 months). Neoadjuvant chemotherapy with interval debulking surgery appeared to be safe and feasible in patients with metastatic epithelial ovarian carcinoma.
