Abstract

PURPOSE:

Dose-dense regimens have been shown to improve outcome when given as adjuvant therapy to patients with breast cancer compared with their three weekly counterparts. We investigated the feasibility of a dose-dense regimen with carboplatin/paclitaxel followed by pegfilgrastim in patients with advanced ovarian cancer. We also investigated the toxicities including the percentage of patients with grade 2 or greater peripheral neurotoxicity and the clinical response of this regimen.

PATIENTS AND METHODS:

Women with untreated Stage III or IV epithelial ovarian, (fallopian) tubal, or primary peritoneal cancer were treated with carboplatin area under the curve (AUC) 5 and paclitaxel 175 mg/m(2) day one, and pegfilgrastim 6 mg day two every 2 weeks for six cycles.

RESULTS:

Between 9/06 and 9/08, 43 patients enrolled. Thirty-one patients completed six or more cycles of therapy. The dose limiting toxicities resulting in treatment discontinuation included: grade 3 and 4 neuropathy, grade 4 thrombocytopenia, grade 4 thrombocytopenia/grade 3 febrile neutropenia, and grade 4 supraventricular tachycardia. Twelve patients (30%) had >or=grade 2 neuropathy from this regimen. The overall response rate in patients with measurable disease was 58% (11 out of 19).

CONCLUSION:

Dose-dense carboplatin/paclitaxel appears to be effective. However, based on dose limiting toxicities occurring when administering 6 cycles of treatment, it is not feasible. Given the neuropathy and thrombocytopenia, we do not recommend 6 cycles of this regimen without modification.
