A protocol with adjuvant chemotherapy (CT) and radiotherapy (RT) for endometrial cancer: Results.

e16549 Background: The classic adjuvant treatment for high-risk endometrial cancer is RT. Several phase III trials explored the role of CT, as single treatment or added to RT sequentially (ST) or concurrently (CR), but design heterogeneity hampers conclusions. We report the results of a single-institution protocol with adjuvant CT + RT for advanced stages or type II histologies. Key points: (1) ST and CR permitted. (2) CT used pre-, post- and/or during RT: carboplatin AUC 5 + paclitaxel 175 mg/m2 (150 during RT) Q3W, 4-6 cycles (“carbotaxol”). (3) since 2010, cisplatin 50 mg/m2 was used for CR (on day 1 and 28 of RT). CR was preceded/followed by carbotaxol. Methods: All patients (PT) included in the protocol between 1/2005 and 9/2011 were retrospectively revised. Endpoints were survival and toxicity grade 3-4. Kaplan Meier and Fisher test were used. Conclusions: CR-carbotaxol showed a longer progression-free and overall survival than ST without reaching statistical significance (log rank, p= 0.14 and p=0....
