[Treatment of advanced or recurrent cervical cancer by a new BOMP regimen consisting of bleomycin, vincristine, mitomycin-C, and low-dose consecutive cisplatin].

Twenty-five patients with cervical cancer (4 post-operative cases with FIGO stage Ib or IIb, 2 with stage IV, and 19 recurrence) were treated with a new BOMP consisting of bleomycin (5 mg/body, drip, i.v., days 1-7), vincristine (0.7 mg/m2, bolus, i.v., day 7), mitomycin-5 (7 mg/m2, bolus, i.v., day 7) and cisplatin (10 mg/m2, drip, i.v., days 1-7). The mean age of the patients was 54 years (range 30-77). Prior therapy included radiotherapy (13 cases), radical hysterectomy (11), and none (1). Fifteen (79%) of the 19 evaluable patients responded, including 6 with a complete response (CR) lasting over 15 months. Almost all the disease located in lung, liver, bone, and vulva showed a response. In particular, lesions confined to the lung had a 100% CR when the size of each tumor was under 2 cm in diameter even in the case of multiple metastasis. In contrast, 9 patients with pelvic disease had a 56% response with only 1 CR who had no previous radiotherapy. Such a poor response in the pelvic disease was considered to be due to vascularity reduced by prior radiotherapy. The important factors affecting the response to a new BOMP were found to be lesion size, prior radiotherapy, and the site of lesion. Patient age, performance status (PS), and the interval from a previous treatment to BOMP were not of significance with regard to response. The dose limiting factor was hematologic toxicities. Other toxicities including nausea, renal dysfunction, pulmonary fibrosis, and loss of hair were acceptable. Thus, the decrease in the PS of patients due to BOMP was minimal. It is suggested that this regimen will be useful as a neoadjuvant chemotherapy for advanced cervical cancer.
