Neoadjuvant chemotherapy with cisplatin, aclacinomycin A, and mitomycin C for cervical adenocarcinoma--a preliminary study.

Between 1989 and 2002, 28 patients with locally advanced cervical adenocarcinoma (bulky IB-IIIB) were recruited for a pilot study aimed at evaluation of the effectiveness of neoadjuvant chemotherapy with cisplatin, aclacinomycin-A, and mitomycin-C (PAM), followed by radical surgery. This regimen was administrated intra-arterially or intravenously. In addition to patients treated with PAM, we retrospectively analyzed the prognoses of 26 patients in stage I and II, who had been treated between 1975 and 1981 with radical surgery with/without radiation therapy. Twenty-eight patients received PAM therapy as neoadjuvant chemotherapy, and 75.0% of the 16 intra-arterially infused patients showed a response, as did 66.7% of the 12 intravenously infused patients. There was a significant difference in the 5-year prognosis of stage II (PAM group, 72.9%; without-PAM group, 36.4%). The results suggest that, as the free space in the parametrium is widened by neoadjuvant chemotherapy with PAM, it is possible that the tumor could be completely resected by radical hysterectomy. Thus, neoadjuvant chemotherapy with PAM is expected to improve the survival rate of patients with advanced cervical adenocarcinoma by the preliminary study. However, the survival rates of stage II with lymph node metastasis in the without-PAM group seem low, and we must also consider that the various technologies to evaluate and treat the cervical adenocarcinomas, e.g. computed tomography, magnetic resonance imaging, and surgical equipments, had improved during 1989-2002 than was the scenario during 1975-1981, and these improvements contributed to better prognosis. A prospective-randomized study is needed to assess the value of this approach compared with standard management.
