OBJECTIVE: To analyze the efficacy and safety of combination chemotherapy of docetaxel and irinotecan for paclitaxel and carboplatin (TC) -refractory or -resistant ovarian carcinomas and for first treatment of primary clear cell and mucinous ovarian carcinomas. STUDY DESIGN: Between 2002 and 2009, we conducted a prospective Phase II study of the efficacy and safety of combination chemotherapy using docetaxel and irinotecan in 62 patients with TC-refractory or -resistant ovarian carcinoma cases (GOGO-OV2) and 15 patients with primary clear cell and mucinous ovarian carcinoma cases (GOGO-OV3). The dose of docetaxel and irinotecan was determined during our previous Phase I study. RESULTS: A docetaxel plus irinotecan regimen provided a 53% response rate, 6 months progression-free survival (PFS), and 12 months overall survival (OS) for primary clear cell and mucinous ovarian carcinomas (similar to TC therapy). The differences of anti-tumor and survival effects between refractory and resistant cases were not statistically significant. The regimen also provided a 15% response rate, 5 months PFS, and 15 months OS for TC-refractory or TC-resistant cases, when used as a second-line chemotherapy. These data are similar to previous reports, however, our study provides the first data exclusively for the cases refractory or resistant to a gold standard TC therapy as a second-line chemotherapy. The regimen was demonstrated to be well tolerable. CONCLUSION: Combination chemotherapy of docetaxel and irinotecan may be a useful option to treat TC-refractory/resistant cases and primary clear cell and mucinous adenocarcinoma cases of ovarian carcinoma.
