PURPOSE: To evaluate the effectiveness of bevacizumab with single-agent chemotherapy for platinum-resistant ovarian cancer in a real-world setting.
PATIENTS AND METHODS: We enrolled recurrent platinum-resistant ovarian cancer patients from 27 institutions. All had received bevacizumab with single-agent chemotherapy (weekly paclitaxel, pegylated liposomal doxorubicin (PLD), topotecan) between 2015 and 2017 for second- or third-line chemotherapy in routine clinical practice. The primary endpoint was progression-free survival (PFS) and safety. Secondary endpoints included the objective response rate (ORR), PFS2, overall survival, duration of chemotherapy, and reasons for discontinuing chemotherapy.
RESULTS: Of 391 patients, 259 (66.2%) received bevacizumab with PLD, 94 (24.0%) with topotecan, and 38 (9.7%) with weekly paclitaxel. The median PFS was 6.1 months with all forms of bevacizumab-containing therapy. Although the cohort with weekly paclitaxel had a better PFS than the PLD cohort (P = 0.028), this finding was not found in patients with a previous platinum-free interval of less than three months. The median duration of therapy was five cycles (range, one to 20 cycles), and 29 patients (7.4%) discontinued treatment because of adverse events from bevacizumab-containing regimens. The PLD cohort had fewer grade ≥ 3 adverse events than the other regimens (PLD, 35.8%; weekly paclitaxel, 52.6%; topotecan, 51.1%; P = 0.012), especially events of hematologic toxicities.
CONCLUSION: In Korean ovarian cancer patients, the safety and effectiveness of chemotherapy with bevacizumab in a real-world setting was consistent with the results from a randomized controlled study. The effectiveness and toxicity profiles varied among the chemotherapy regimens, and this finding should be considered in practice.
