Landmark chemotherapy trials in advanced ovarian cancer established platinum-based combinations as the standard of care. GOG 47 (1986) showed cisplatin improves response rates and progression-free survival compared to cyclophosphamide alone. GOG 111 (1996) found the combination of paclitaxel and cisplatin improved progression-free and overall survival over cyclophosphamide and cisplatin. Subsequent trials determined carboplatin as an effective alternative to cisplatin, with fewer side effects.

The alkylating agent CYCLOPHOSPHAMIDE got approval
in 1959.
In advanced ovarian cancer for next 2 decades,
CYCLOPHOSPHAMIDE / MELPHALAN along with either
DOXORUBICIN or 5Fu was used.
In 1978 FDA approved platins (cisplatin) for germ cell
tumor , this leads to initiation of various trials in use of
platins in ovarian cancer.
Till then most widely used regimen for ovarian cancer is
CYCLOPHOSPHAMIDE and DOXORUBICIN
