Adjuvant Sequential & Concurrent CarboTaxol + Radiotherapy for High Risk Endometrial Cancer

Status unconfirmed · Phase 2

Conditions studied: Endometrial Cancer

In brief

The purpose of this trial is to evaluate the safety of sequential and concurrent carboplatin and paclitaxel with adjuvant external beam radiotherapy for locally advanced endometrial cancer. The primary objective is to assess the acute toxicities namely grade 3-4 non hematologic and grade 4 hematologic toxicities associated with the above regimen. The null hypothesis is that the unacceptable toxic response rate is ≥40%. This will be tested against a one-sided alternative that the toxicity rate is 20% or less. Simon's two-stage design was used to power this aim. In the first stage, 11 patients will be accrued. If there are 5 or more toxic responses in these 11 patients, the study will be stopped for safety reasons. Otherwise, 13 additional patients will be accrued for a total of 24 patients. Under these conditions, the probability of stopping early is 47% if the toxic response rate is truly higher than 20.0%. If this regimen is safe then its efficacy can be studied in a Phase III study.
