Summary

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.

Conditions

Interventions

DRUG

Carboplatin and Paclitaxel

Regimen I: Carboplatin AUC 6 \& Paclitaxel 175mg/m2 given intravenously for 4 cycles during weeks 1, 10, 13, 16 Regimen II: Carboplatin AUC 2 \& Paclitaxel 45mg/m2 given intravenously for 2 cycles during weeks 4 \& 7 concurrent with radiotherapy

RADIATION

Radiation Therapy

An external beam radiation dose of 45 Gy in 25 fractions is routinely prescribed to the Planning Target Volume (PTV) for postoperative radiotherapy. The Vaginal Brachytherapy (VBT) Boost will be delivered after the external beam radiation. Doses of 12-18 Gy in 2-3 fractions are often prescribed to the surface of the vagina to a treatment length of 3-5 cm. There is no standard dose or fractionation schedule, so this dose, fractionation, location of dose specification , and length of vagina treated will be individualized for the patient and will be at the discretion of the treating radiation oncologist.
