Abstract

Retinoids are strong inhibitors of epithelial cancer promotion and progression in experimental carcinogenesis. Recently, therapeutic trials of retinoids have demonstrated activities in cervical cancer and precancerous lesion of cervix. Our purpose was to determine whether additional administration of 13-cis-retinoic acid would improve the treatment effect of neoadjuvant chemotherapy in patients with squamous cell carcinoma of the cervix. From January 1994 through January 1995, 40 patients with invasive cervical cancer were enrolled in this prospective study and randomized into the two groups. Group 1 had neoadjuvant chemotherapy alone and group 2 had neoadjuvant chemotherapy plus 13-cis-retinoic acid (RA) at a dosage of 1 mg/kg/day for 1 month. Patients in group 1 and group 2 were similar with respect to age, parity, clinical stage, and histological subtype. Therapeutic responses were compared using Fisher's exact test, Mann-Whitney test, and Wilcoxon signed-rank test. RA increased the complete response rate of neoadjuvant chemotherapy from 0% in group 1 to 5% in group 2. However, a difference of overall clinical response rate between the two groups was not evident. The drug toxicities in group 1 and group 2 included anemia in 30.0% and 23.7%, leukopenia in 6.7% and 15.2%, and hepatotoxicity in 6.7% and 6.8%, respectively. More frequent incidence of mucocutaneous side effects was seen in group 2 than group 1, but these side effects were mild and reversible. The clinical response rate achieved in this trial indicates that the combination of 13-cis-retinoic acid and neoadjuvant chemotherapy, at least when used on the schedule reported herein, is not superior to treatment of neoadjuvant chemotherapy alone for patients with squamous cell carcinoma of the cervix. However, a single patient achieved a complete response on this therapy, and the impact of such a treatment on survival needs to be explored.
