Randomized Phase III Trial of Paclitaxel and Carboplatin Versus Paclitaxel and Ifosfamide in Patients With Carcinosarcoma of the Uterus or Ovary: An NRG Oncology Trial
Journal of clinical oncology : official journal of the American Society of Clinical Oncology Β· Mar 2022 Β· randomized phase III trial
This randomized phase III study compared paclitaxel plus carboplatin with paclitaxel plus ifosfamide in adults with uterine or ovarian carcinosarcoma. In uterine carcinosarcoma, paclitaxel plus carboplatin was not inferior to the ifosfamide regimen and had longer median overall survival and progression-free survival. Toxicities were broadly similar, although some side effects differed between the two groups.
Reported effects: median OS 37 mo, p P < .01 for noninferiority, P > .1 for superiority, n=449 Β· HR 0.87 [0.7β1.075], p P < .01 for noninferiority, P > .1 for superiority, n=449 Β· +4 more
Studied with: carboplatin, ifosfamide.
Key findings
- In uterine carcinosarcoma, paclitaxel plus carboplatin was not inferior to paclitaxel plus ifosfamide for overall survival.
- Median overall survival was 37 versus 29 months in uterine carcinosarcoma.
- Median progression-free survival was 16 versus 12 months in uterine carcinosarcoma.
- Toxicities were similar overall, with more hematologic toxicity in the paclitaxel-carboplatin arm and more confusion and genitourinary hemorrhage in the paclitaxel-ifosfamide arm.
- In ovarian carcinosarcoma, paclitaxel plus carboplatin had numerically longer survival outcomes, but the differences were not statistically significant.
This study evaluates chemotherapy regimens in carcinosarcoma, a cancer setting, with direct survival and toxicity outcomes.
