Intraperitoneal (IP) chemotherapy improves survival in ovarian cancer but its use has been limited by toxicity with cisplatin-based regimens. The primary objective of this study was to define the maximum tolerated dose and dose-limiting toxicity of intravenous (IV) oxaliplatin and IP docetaxel in women with recurrent ovarian, fallopian tube or peritoneal cancer. Secondary objectives were response rate, time to progression, symptom interference with quality of life, and pharmacokinetics. Patients received a constant dose of oxaliplatin 75 mg/m2 IV on day 1 and docetaxel escalating from 50 mg/m2 IP on day 2 every 3 weeks using a 3 + 3 design. Treatment continued until disease progression, remission, or intolerable toxicity occurred. Plasma and IP samples were taken to determine drug concentrations. Patients completed the MD Anderson Symptom Inventory weekly. Twelve patients were included. The median number of cycles was 4 (range 2-6) with a median time to progression of 4.5 months. Among eight patients with measurable disease, the best responses were partial response in two patients, stable disease in five, and progressive disease in one. A total of 14 grade 3-4 toxicities were noted, most commonly hematologic. Four patients, all dose level 3, had six dose-limiting toxicities: two with prolonged neutropenia, one with infection, one with hyponatremia, and two with abdominal pain. Dose level 3 was therefore considered intolerable. The mean±SD ratio of docetaxel area under the curve (AUC) in IP fluid to AUC in plasma was 229±111. Symptom interference with life activities steadily decreased from cycle 1 to 5. Oxaliplatin 75 mg/m2 IV on day 1 and docetaxel 75 mg/m2 IP on day 2 was the maximum tolerated dose. Most patients had partial response or stable disease, even in a heavily pre-treated population. At this dose level, patient-reported outcomes demonstrate temporary but tolerable decrements in quality of life.
