From randomized trial to practice: single institution experience using the GOG 172 i.p. chemotherapy regimen for...

The objective of the study was to evaluate completion rates and toxic effects of an i.p. chemotherapy regimen in a cross-section of nonselected patients with ovarian cancer (OC).

All patients with stage IIIC OC consecutively operated at our institution from January 2006 to December 2007 were prospectively collected and analyzed.

Eighty-nine patients with stage IIIC OC optimally debulked were evaluated for this study. An i.p. port was primarily placed in 53 of 89 (60%), and i.p. chemotherapy was recommended in 55 patients. Reasons for not recommending i.p. chemotherapy in patients optimally debulked included postoperative complications (n = 7: 8%), poor nutritional/functional status (n = 5: 6%), and extensive surgery including bowel resection (n = 9: 10%). Thirty-three patients (33/55: 60%) recommended to receive i.p. chemotherapy-initiated i.p. treatment. Fifty-two percent of those beginning i.p. therapy (17/33) received three or more cycles with 36% (12/33) successfully completing six cycles. Reasons for discontinuation included grade 3-4 nephrotoxicity in 3 of 21 (14%), febrile neutropenia/sepsis in 3 of 21 (14%), port infection or malfunction in 8 of 21 (38%).

The i.p. chemotherapy regimen used in a consecutive cohort of patients carries could be completed in only a small percentage of patients. Less toxic regimens with higher acceptability should be considered.
