Objective

This study aimed to evaluate the efficacy and safety of hyperthermic intraperitoneal intraoperative chemotherapy (HIPEC) in patients with advanced ovarian cancer.

Methods

A total of 200 patients with advanced ovarian cancer were enrolled in this retrospective study and randomly allocated to two groups (research registry number: 11353). On the first day after abdominal closure, routine treatment was performed in the non-HIPEC group, whereas HIPEC was performed in the HIPEC group. The surgical outcomes, overall survival, progression-free survival, side effects, and quality of life of patients were compared between the two groups, and the risk factors for overall survival and progression-free survival were analyzed.

Results

The basic information of the patients showed no significant difference between the two groups (p > 0.05). There was no significant difference in the time from surgery to first flatus, postoperative hospital stay, abdominal pain, bleeding, leakage, or other blood indices between the two groups (p > 0.05); however, the symptoms of ileus and pelvic abscess appeared more frequently in the non-HIPEC group (p < 0.05). HIPEC, tumor size, N stage, T stage, and vascular invasion were significant indicators, while HIPEC, tumor size, vascular invasion, N stage, and T stage were independent prognostic factors. The 3-year survival rate of the HIPEC group (42%) was higher than that of the non-HIPEC group (21%) (p < 0.001). The progression-free survival curve of the HIPEC group was superior to that of the non-HIPEC group (p  <  0.001), and the recurrence rate of the HIPEC group (25%) was lower than that of the non-HIPEC group (49%) (p  <  0.001).

Conclusions

HIPEC can reduce the possibility of perioperative complications such as intestinal obstruction and pelvic abscess, and the overall survival and progression-free survival curves were better in the HIPEC group.
