Purpose
1.1 To determine the regulation of topoisomerase I and II following alternating prolonged exposure to topotecan and etoposide (VP-16)
1.2 To determine the time to progression and the objective response rate of this treatment in patients with incurable ovarian cancer.

- To determine the regulation of topoisomerase I and II following alternating prolonged exposure to topotecan and etoposide (VP-16) [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]
- To determine the time to progression and the objective response rate of this treatment in patients with incurable ovarian cancer [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]

Drug: Topotecan and VP16
Course 1A: On day 1 treatment will start with a continuous infusion of TPT at 0.4 mg/m2/day for 21 days. A pump will be used to deliver the TPT. The bag in the pump will be replaced every week for sterility precautions.
Course 1B: On day 28, if ANC is >1,500 and platelets > 100,000, VP-16 will be administered orally at 50 mg/day for 14 days.
The rationale to study the downregulation of topoisomerase enzyme in ovarian cancer in relationship to the cell cycle distribution of the cancer cells after a prolonged continuous exposure to topo I and II poisons is to better understand the relationship between cell cycle and topo poisoning, which may lead to better clinical trial designs.
Eligibility| Ages Eligible for Study: | 18 Years and older |
| Genders Eligible for Study: | Female |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- All patients, 18 years of age or older, with incurable ovarian advanced cancer are eligible provided that they have measurable disease by CT-scan imaging, or evaluable disease by tumor markers, following the criteria described by Rustin et al. (14). (Response to a specific treatment has occurred if after two CA-125 samples there has been a 50% decrease, confirmed by a fourth sample (50% response), or a serial decrease over three samples of greater than 75% (75% response). The final sample has to be at least 28 days after the previous sample.)
- Patients must have a life expectancy of at least 12 weeks.
- Patients must have a Zubrod performance status of 0-2.
- Patients must sign an informed consent.
- Patients should have adequate bone marrow function defined by an absolute peripheral granulocyte count of > 1,500 or cells/mm3 and platelet count >100,000/mm3 and absence of a regular red blood cell transfusion requirement.
- Patients should have adequate hepatic function with a total bilirubin < 2 mg/dl and SGOT or SGPT < two times the upper limit of normal, and adequate renal function as defined by a serum creatinine < 1.5 x upper limit of normal.
Exclusion Criteria:
- Patients with symptomatic brain metastases are excluded from this study.
- Pregnant women or nursing mothers are not eligible for this trial. Patients of child bearing potential must use adequate contraception.
- Patients may receive no other concurrent chemotherapy or radiation therapy during this trial.
- Patients with severe medical problems such as uncontrolled diabetes mellitus or cardiovascular disease or active infections are not eligible for this trial.
