A multicentre, phase II study of carboplatin and paclitaxel (CbP) in chemotherapy-naïve patients with advanced thymic carcinoma has shown that the treatment has promising efficacy compared with standard anthracycline-based chemotherapy.
Thymic carcinoma is very rare, and consequently it is hard to investigate it separately from thymoma. Previous studies evaluating chemotherapy regimens have included patients with both types of tumour, explain Takashi Seto (National Kyushu Cancer Center, Fukuoka, Japan) and colleagues.
Forty patients from 21 centres across Japan were enrolled in the current study from May 2008 until November 2010. One patient subsequently dropped out. The sample size was decided on the basis that it was large enough to reject the primary endpoint of an objective response rate (ORR) of 20%.
