title: A recurrent ovarian cancer patient with a history of nine prior chemotherapy regimens who was safely treated with weekly paclitaxel plus bevacizumab and achieved a complete response: a case report.
abstract: Herein, we describe our experience with a recurrent ovarian cancer patient who was treated safely with bevacizumab and who achieved a complete response despite receiving nine prior chemotherapy regimens. The patient was a 54-year-old woman with stage IIIC recurrent ovarian serous adenocarcinoma (grade 3). Computed tomography (CT) revealed that no evidence of ascites, multiple intraperitoneal dissemination, or intrapelvic lymph node metastases was present. The absence of bowel obstruction and disseminated lesions involving the intestinal tract was confirmed by CT. Performance status was 0, and a blood test also indicated preservation of major organ function. In our hospital, weekly paclitaxel plus bevacizumab therapy (paclitaxel at 80 mg/m(2) on days 1, 8, and 15; bevacizumab at 15/mg/kg on day 1 and every 21 days thereafter) was started. Eight cycles were administered, with no signs of gastrointestinal perforation, and the antitumor effect was evaluated as a complete response. The observed adverse events included grade 1 hyponatremia and grade 1 hypochloremia, and there was one grade 1 sensory peripheral neuropathy. These adverse events neither delayed treatment nor necessitated any dosage reductions. This case suggests that bevacizumab can be safely administered even to patients with recurrent ovarian cancer who have received three or more prior chemotherapy regimens if there are neither symptoms of bowel obstruction nor lesions suggestive of intestinal invasion on diagnostic imaging.
