Trials performed in the past 15 years by the Gynecologic Oncology Group ide
ntified as optimal a platinum/taxane combination as the backbone to treat c
hemonaive ovarian cancer. Comparison to a triplet adding a third drug to th
e backbone is least likely to significantly improve outcome, however, of th
e drugs currently available for addition; doxil, etoposide, gemcitabine, an
d topotecan; none appears to be any better or worse than was paclitaxel a d
ecade ago. An approach more likely to improve outcome would be to incorpora
te as many of these "new" drugs as possible using sequential doublets. Some
doublets have a better biochemical rationale such as cisplatin and gemcita
bine (inhibition of DNA repair) or topotecan and either doxil or etoposide
(upregulation of topoisomerase II levels by topotecan followed by a topoiso
merase II inhibitor.
