About

The purpose of this research study is to determine the feasibility and safety of giving the combination of oxaliplatin and gemcitabine followed by radiation therapy and to learn whether or not this drug combined with radiation therapy works in treating women with Mullerian tumors of the uterus.

Full description

OBJECTIVES:

Primary To determine the feasibility of dual modality therapy described as cytotoxic therapy followed by radiation therapy for the management of Malignant Mixed Mullerian Tumors (MMMTs).

Secondary

* To describe the response rate by Response Evaluation Criteria in Solid Tumors

STATISTICAL DESIGN:

This study used a two-stage design to evaluate feasibility of oxaliplatin and gemcitabine prior to radiation therapy defined as completing 3 cycles of chemotherapy. The null and alternative therapy completion rates were 25% and 50%. If 3 or more participants enrolled in the stage one cohort (n=9 participants) complete therapy than accrual would proceed to stage two (n=15 participants). If therapy was completed by at least 10 participants in the final set of 24 evaluable participants then this regimen would be deemed worthy of further study. This design had 80% power given one-sided type I error of 5% with the probability of stopping early 0.60.

Enrollment: 20 patients

Experimental group

Description:

Patients rcvd IV chemotherapy on days 1 and 15 of a 4-week cycle: gemcitabine 1000 mg/m2 and oxaliplatin 65 mg/m2 for up to 3 cycles. Two dose reductions per study drug were permitted. On study, chemotherapy was followed by radiation therapy (RT) within 4-6 weeks of last chemotherapy. RT regimen was tumor-volume directed.

Treatment:

Radiation: Radiation

Drug: Oxaliplatin

Drug: Gemcitabine
