Oxaliplatin salvage for recurrent ovarian cancer: a single institution's experience in patient populations with platinum resistant disease or a history of platinum hypersensitivity.


PMID 24769036

Abstract

Hypersensitivity reactions can preclude platinum re-challenge for patients receiving second-line and higher carboplatin/cisplatin salvage therapy. The objective is to report our patient experience with oxaliplatin in recurrent or progressive epithelial ovarian (EOC), primary peritoneal (PPC) or fallopian tube cancer (FTC), including those with prior hypersensitivity reaction. A single institution, retrospective review from 1995 to 2012 of patients receiving oxaliplatin for treatment of recurrent or progressive EOC, PPC, or FTC was performed. Data collected included patient demographics, diagnosis date, prior chemotherapy regimens, platinum-free interval(s), prior hypersensitivity reactions, oxaliplatin toxicity, length of therapy, disease response, and last follow-up. Those who received ≥1 cycles were included. A response to therapy was determined after ≥2 cycles. Forty-four patients were identified. All had prior carboplatin and 38.6% had prior cisplatin therapy. Twenty-three had a prior platinum hypersensitivity reaction. Patients received a median of 2 prior platinum containing regimens and 5 chemotherapy lines prior to oxaliplatin exposure. One patient experienced grade 3 pain. No grade 4 toxicities occurred. No treatment delays for pancytopenia noted. Nausea and dysesthesias were controlled medically and weren't dose-limiting. No nephropathy or neuropathy progressed on oxaliplatin or were dose-limiting. Disease response was observed in 43.2%. Of the responders, 36.8% had a prior platinum hypersensitivity reaction. Median number of 5 cycles of an oxaliplatin containing regimen was given. Median follow-up was 15.5 months. In our experience, oxaliplatin is well tolerated and should be considered for platinum challenge after hypersensitivity even in patients with platinum resistant disease with a reasonable chance of response.
