RATIONALE: Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. It is not yet known which chemotherapy regimen is more effective in treating sex cord-ovarian stromal tumors.
PURPOSE: This randomized phase II trial is studying paclitaxel and carboplatin to see how well they work compared with bleomycin sulfate, etoposide phosphate, and cisplatin in treating patients with advanced or recurrent sex cord-ovarian stromal tumors.
- To compare the progression-free survival of patients with advanced or recurrent sex cord-stromal tumors of the ovary treated with paclitaxel and carboplatin versus bleomycin sulfate, etoposide phosphate, and cisplatin.
- To estimate the toxicity of these regimens in this patient population.
- To compare the overall survival of patients treated with these regimens.
- To evaluate response rate in a subset of patients with measurable disease.
- To collect fixed and/or frozen tumor tissue for future translational research studies.
- To explore the utility of inhibin A and inhibin B as prognostic and predictive biomarkers for ovarian sex cord-stromal tumors and to examine changes in these markers in response to treatment.
OUTLINE: This is a multicenter study. Patients are stratified according to presence of measurable disease (yes vs no). Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive paclitaxel IV over 3 hours and carboplatin IV over 1 hour on day 1. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity.
- Arm II: Patients receive bleomycin sulfate IV on day 1 and etoposide phosphate* IV over 1 hour and cisplatin IV over 30 minutes on days 1-5. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity.
NOTE: *Patients who have received prior radiotherapy receive etoposide phosphate on days 1-4.
Patients undergo blood sample collection at baseline and periodically during study for laboratory biomarker analysis.
After completion of study therapy, patients are followed up every 3 months for 2 years, every 6 months for 3 years, and then annually thereafter.

Experience with substituting carboplatin for cisplatin is limited in advanced and recurrent cervix cancer and there has been no counterpart to GOG 158, which documented therapeutic equival...
To compare the efficacy of olaparib in combination with paclitaxel and carboplatin when compared with carboplatin and paclitaxel alone in patients with advanced ovarian cancer.

A semisynthetic derivative of PODOPHYLLOTOXIN that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle.
A complex of related glycopeptide antibiotics from Streptomyces verticillus consisting of bleomycin A2 and B2. It inhibits DNA metabolism and is used as an antineoplastic, especially for solid tumors.
An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
Derivatives of chondroitin which have a sulfate moiety esterified to the galactosamine moiety of chondroitin. Chondroitin sulfate A, or chondroitin 4-sulfate, and chondroitin sulfate C, or chondroitin 6-sulfate, have the sulfate esterified in the 4- and 6-positions, respectively. Chondroitin sulfate B (beta heparin; DERMATAN SULFATE) is a misnomer and this compound is not a true chondroitin sulfate.
An enzyme that catalyzes the activation of sulfate ions by ATP to form adenosine-5'-phosphosulfate and pyrophosphate. This reaction constitutes the first enzymatic step in sulfate utilization following the uptake of sulfate. EC 22.214.171.124.
