Thirty patients with bulky advanced ovarian cancer surgically not resectable, received combination chemotherapy (median of 4.1 cycles; range, 3-7) including cisplatin or carboplatin, followed by a second surgical effort. Clinical CR + PR was observed in 24/30 (80%) patients after chemotherapy. Our study deals only with these 24 patients, and the 6 patients who did not respond to chemotherapy are not part of this report. At debulking, 7/24 (29.1%) patients had a complete macroscopic resection; 9/24 (37.5%) patients had a partial resection (residual tumor less than 2 cm). These data suggest that debulking is feasible and successful after chemotherapy containing cisplatin or its derivative. Overall median survival from diagnosis was 18.9 months; the 3-year survival rate was 28%. Median progression-free survival from diagnosis was 13.5 months. The results observed in our study indicate that the use of induction chemotherapy can play an important role in increasing the chances of optimal debulking in patients presenting with unresectable ovarian cancer.
Twelve FIGO stage III-IV ovarian cancer patients progressing or relapsing after primary cisplatin-containing combination chemotherapy were treated with ifosfamide and etoposide. Only patients with clinically evaluable disease entered the trial. The 12 patients received a median number of 3 courses (range 1-6). No complete or partial response and two disease stabilizations were observed. Ten patients progressed on therapy. The combination of ifosfamide and etoposide does not appear to be an effective salvage treatment for advanced ovarian cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
