Weekly administration of topotecan-paclitaxel as second-line treatment in ovarian cancer.
OBJECTIVE
To investigate the weekly administration of topotecan combined with paclitaxel in pretreated advanced ovarian cancer patients; our objectives were to determine efficacy, toxicity and survival.


METHODS
The chemotherapy agents, topotecan and paclitaxel were administered on a weekly basis for 3 consecutive weeks, every 28 days. The plan was to give three courses (each course included three once-weekly infusions). The dose of topotecan was 1.75 mg/m(2) and of paclitaxel 70 mg/m(2).


RESULTS
From January 2004 until January 2006, 45 patients were enrolled in this multicenter trial; 44 patients were evaluable for response and toxicity. The median age was 60 years old (range 39-82 years) and performance status was 0-2. Thirty-nine patients were in stage III and 5 in stage IV. All patients had been pretreated with carboplatin or cisplatin in combination with paclitaxel. Complete and partial responses were seen in 39% of the patients, stable disease in 43% and progressive disease in 18%; median survival time was 9 months, range 2-24+ months, (95% CI: 7.9-10.2). There was a notable absence of grade 3 toxicity except for neutropenia in 11% of the patients.


CONCLUSIONS
The combination of topotecan and paclitaxel administered on a weekly basis is a well-tolerated chemotherapy schedule. The response rate of 39% is quite high for patients with pretreated ovarian cancer.
