CHAP II therapy for epithelial ovarian cancers following primary treatment with platinum-based combination...

Nineteen patients with stage III or IV epithelial ovarian cancer treated on a prospective randomized protocol with either adriamycin and cis-diamminedichloroplatinum or tamoxifen, adriamycin, and cis-diamminedichloroplatinum received a modified "CHAP II" regimen at the time of clinical progression of disease or the finding of occult cancer at second-look surgery. One patient had a clinical complete response lasting 6 months, one had a partial response lasting 23 months, 6 had clinically stable disease for an average of 6.5 months (range 4-15 months), 8 patients had progressive disease, and 3 patients without clinically detectable disease remained disease free for a mean time of 10 months (range 7-16 months). The modified "CHAP II" regimen employed in this study for patients failing prior cis-diamminedichloroplatinum-based regimens appears to have only limited efficacy in inducing objective remissions.
