DISEASE CHARACTERISTICS:

  • Disease progression defined as CA-125 > 2 times upper limit of normal (ULN)documented on 2 separate determinations (made > 2 weeks apart, with the most recent being completed with the past 7 days) and the following criteria are met:

    • Physical exam is normal
    • Maximum lesion diameter < 20 mm by CT scan with conventional techniques or < 10 mm by spiral CT scan
• No known brain metastases

PATIENT CHARACTERISTICS:

  • Prior malignancy allowed provided the patient has completed anticancer therapy and is considered to be < 30% of risk of relapse by the treating physician
• Absence of any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol and follow-up schedule

PRIOR CONCURRENT THERAPY:

• See Disease Characteristics
• Prior radiotherapy allowed provided there is documented progression (either locally or systemically)
• Up to 2 prior lines of chemotherapy for recurrent or metastatic disease allowed
• At least 4 weeks since prior chemotherapy, radiotherapy, or surgery (6 weeks for nitrosoureas or mitomycin C) and recovered to grade ≤ 1 toxicities except peripheral neuropathy and alopecia
