This randomized phase II trial studies paclitaxel and carboplatin to see how well they work compared with bleomycin sulfate, etoposide phosphate, and cisplatin in treating patients with sex cord-ovarian stromal tumors that have spread to other places in the body and usually cannot be cured or controlled with treatment (advanced) or has returned (recurrent). Drugs used in chemotherapy 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. 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.
PRIMARY OBJECTIVES: I. To assess the activity of paclitaxel and carboplatin with respect to progression free survival (using bleomycin, etoposide, and cisplatin \[BEP\] as a reference) for newly diagnosed advanced or recurrent chemonaive ovarian sex cord-stromal tumors. SECONDARY OBJECTIVES: I. To estimate the toxicity of paclitaxel and carboplatin, and bleomycin, etoposide, and cisplatin in this patient population. II. To estimate overall survival for paclitaxel and carboplatin relative to that of BEP. III. To evaluate response rate in the subset of patients with measurable disease. TERTIARY OBJECTIVES: I. To collect fixed and/or frozen tumor tissue for future translational research studies. II. 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 with treatment. OUTLINE: Patients are randomized to 1 of 2 treatment arms. ARM I: Patients receive paclitaxel intravenously (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. 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.

Progression-free Survival (PFS)
The relationship of randomized treatment to progression free survival. The RECIST 1.1 criteria are used for disease progression. This is the criteria: progression is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progressions).
Time frame: From start of treatment to time of progression or death, whichever occurs first. Median follow-up time was 48 months.
Tumor Response Rate
Proportion of evaluable patients with complete or partial tumor response by RECIST 1.1 criteria. Complete Response (CR): Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to \<10 mm. Partial Response (PR): At least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum diameters. (ORR = CR + PR).
Time frame: Median followup time was 48 months.
Overall Survival (OS)
The relationship of treatment to overall survival will be assessed. The number of death events in the treatment arm is reported.
Time frame: From start of treatment to time of death or the date of last contact, assessed up to 10 years. Median follow-up time was 48 months.
