Gemcitabine Hydrochloride and Docetaxel Followed by Doxorubicin Hydrochloride or Observation in Treating Patients With High-Risk Uterine Leiomyosarcoma Previously Removed by Surgery

Phase 3

Terminated

Conditions: Stage I Uterine Sarcoma AJCC v7
Uterine Corpus Leiomyosarcoma

Interventions: Other: Clinical Observation
Drug: Docetaxel
Drug: Doxorubicin Hydrochloride
Biological: Filgrastim
Drug: Gemcitabine Hydrochloride
Biological: Pegfilgrastim

Registration Number: NCT01533207

Lead Sponsor: Gynecologic Oncology Group

Brief Summary: This randomized phase III trial studies how well gemcitabine hydrochloride and docetaxel followed by doxorubicin hydrochloride work compared to observation in treating patients with high-risk uterine leiomyosarcoma previously removed by surgery. Drugs used in chemotherapy, such as gemcitabine hydrochloride, docetaxel, and doxorubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether combination therapy after surgery is an effective treatment for uterine leiomyosarcoma.

Detailed Description: PRIMARY OBJECTIVES:

I. To determine whether overall survival of patients with uterus-limited high-grade leiomyosarcoma is superior among patients assigned to treatment with adjuvant gemcitabine hydrochloride (gemcitabine) plus docetaxel followed by doxorubicin hydrochloride compared to patients assigned to observation.

SECONDARY OBJECTIVES:

I. To determine whether treatment with adjuvant gemcitabine plus docetaxel followed by doxorubicin improves recurrence-free survival of patients with uterus-limited high-grade leiomyosarcoma compared to observation.

II. To explore the impact of potential predictors of recurrence or death such as patient age, institution reported tumor size, cervix involvement (yes or no), and mitotic rate.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

Arm I: Patients receive adjuvant gemcitabine hydrochloride IV over 70-90 minutes on days 1 and 8 and docetaxel IV over 30-60 minutes on day 8. Patients also receive filgrastim subcutaneously (SC) on days 9-15 or pegfilgrastim SC on day 9 or 10. Treatment repeats every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. Patients then undergo computed tomography (CT) and/or magnetic resonance imaging (MRI). Patients with no evidence of disease receive doxorubicin hydrochloride IV every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients also receive filgrastim SC on days 2-8 or pegfilgrastim SC on day 2 or 3.

Arm II: Patients undergo clinical observation.

After completion of study treatment, patients in both arms are followed up every 4 months for 3 years and then every 6 months for 2 years.

Patients participating through United States (U.S.) sites must sign an approved and authorization permitting release of personal health information
Patients should be free of active infection requiring antibiotics (with the exception of an uncomplicated urinary tract infection [UTI])

Exclusion Criteria

Patients who have had prior therapy with docetaxel, gemcitabine hydrochloride, or doxorubicin hydrochloride at any time in their history
Patients with a history of other invasive malignancies, with the exception of non-melanoma skin cancer, are ineligible if there is any evidence of other malignancy being present within the last five years; patients are also ineligible if their previous cancer treatment contraindicates this protocol therapy
Patients with a history of severe hypersensitivity reaction to Taxotere (docetaxel) or other drugs formulated with polysorbate 80
Patients with GOG performance status of 2, 3 or 4; or ECOG performance status of 2, 3 or 4
Patients who are breast-feeding
Patients with a known history of congestive heart failure or cardiac ejection fraction < 50% (or less than institutional normal limits); echocardiogram (ECHO) or multigated acquisition scan (MUGA) is not required prior to enrollment; for patients assigned to the chemotherapy arm, an ECHO or MUGA should be done within 6 months of day 1 of gemcitabine-docetaxel treatment
- Patients who enroll on study and are randomized to Regimen I (chemotherapy ) and then are found on baseline ECHO or MUGA to have cardiac ejection fraction < 50% or below institutional normal will remain ON study; such patients will receive gemcitabine + docetaxel for 4 cycles but will NOT receive any doxorubicin treatment; they will continue treatment follow-up as outlined for all patients assigned to Regimen I
