A possible new trend in the management of the carcinoma of the cervix uteri

Thirty-three patients with locally advanced carcinoma of the cervix were treated with chemotherapy as first line treatment. Great emphasis was applied to document, in the most objective manner, the tumor size response. The first 8 patients received a conventional scheme composed of vincristine, bleomycin and cis-platinum (VBP) at 21-day intervals. The results were not as satisfactory as expected. In the other 25 patients a more aggressive VBP scheme was used, at 10-day intervals. Surprisingly satisfactory results and tolerance were observed. In many instances verified tumor reduction allowed surgical radical treatment in prechemotherapy inoperable cases.

Lymph node metastases in carcinoma of the cervix uteri: Response to neoadjuvant chemotherapy and its impact on survival

One hundred and sixty-nine patients with squamous cancer of the cervix uteri treated with three courses of neoadjuvant chemotherapy with the modified VBP scheme are presented. All were subjected to a Wertheim-Meigs operation with paraaortic lymph-adenectomy. The incidence of lymph node metastases is analyzed according to clinical stage, tumor volume, residual tumor in the surgical specimen, and clinical response to neoadjuvant chemotherapy. A significant decrease in the incidence of lymph node involvement was observed in good responders. Survival rates, after 2 years of follow-up, improved in those cases with small residual tumor, negative parametria, and negative nodes.

Results of a Phase II trial with neoadjuvant chemotherapy in carcinoma of the cervix uteri

Results of a Phase II trial with neoadjuvant chemotherapy in carcinoma of the cervix uteri (VBP modified scheme) show that 85.7% of patients given this therapy were NED in Stage IIb versus 54% of a nonrandomized control group given conventional therapy. In Stage IIIb the averages are 66.6% vs. 31% in the control group. Analysis of the ecographic data has shown that if a critical prechemotherapy volume (120 cm3) is exceeded, the prognosis is unfavorable, especially in cases treated with radiotherapy as second-line treatment.

Is subradical surgical treatment for carcinoma of the cervix uteri stage IB logical

Twenty-eight patients with squamous carcinoma of the cervix FIGO stage Ib were treated with three courses of neoadjuvant chemotherapy with a VBP modified scheme. Clinical responses showed that the percentage of complete and moderate responses exceeds 95% of the cases. Clinical response was also related to tumor bulk measurement by ultrasound scanning. Twenty-three of the patients were then subjected to the Wertheim-Meigs operation. Pathological findings of surgical specimens showed absence of residual lesion in 6 patients (26.1%) and carcinoma smaller than 0.5 cm in 5 patients (21.7%). Tumor response to neoadjuvant chemotherapy was excellent in NG3, MG3 tumors when lymphoplasmomonocytic infiltration was present. In accord with this result a new protocol was developed.
