Abstract

OBJECTIVES:

The objective of the study was to assess the feasibility, toxicity, and reasons for early discontinuation of a modified outpatient intraperitoneal/intravenous (IP/IV) chemotherapy regimen for the treatment of patients with optimally debulked stage III ovarian cancer.

METHODS:

Between February 2006 and November 2008, 51 consecutive patients from Institutions of the Spanish Ovarian Cancer Group (GEICO) were treated with a modified outpatient IP chemotherapy regimen. Patients received IV paclitaxel 175 mg/m over 3 hours on day 1, followed by IP cisplatin 100 mg/m (or 75 mg/m according to the principal investigator's criteria) on day 2. On day 8, patients received IP paclitaxel 60 mg/m. To homogenize the IP administration and supportive measures, a GEICO guideline for IP chemotherapy was established. Patients were treated with the intention to receive 6 courses of chemotherapy every 21 days.

RESULTS:

The median age of the patients was 49 years (range, 36-75 years), and most of them had papillary serous ovarian cancer (78%), International Federation of Gynecology and Obstetrics stage IIIC (76%). Thirty-nine patients completed 4 or more IP cycles, and 28 (61%) completed all 6 IP cycles. Twenty-two patients discontinued the IP/IV treatment, mainly because of chemotherapy toxicity (10 patients) and catheter-related complications (5 patients). The most prevalent grade 3/4 toxicities were neutropenia (14 patients; 30%) and gastrointestinal events (12 patients; 26%).

CONCLUSIONS:

The GEICO outpatient modified regimen resulted in a lesser toxicity and a greater rate of treatment completion than previously reported. The accurate selection of patients and the administration following well-defined guidelines can increase the feasibility of IP chemotherapy administration.
