Abstract
The incidence of stage Ib~IIa of cervical adenocarcinoma accounts about 60 to 70% of all patients. This study aims to investigate the prognostic significance of protein estrogen receptor alpha (ERα) and transforming growth factor beta 1 (TGF-β1) level in different glandular epithelia of the cervix. In this study, immunohistochemistry was used to detect ERα and TGF-β1 in carcinomas and incisal margins of 66 cases with cervical adenocarcinoma, 20 cases with normal cervix, and 20 cases with chronic cervicitis. Uni- and multivariate analysis was applied to evaluate the prognostic significance of TGF-β1 and ERα in carcinomas. The results indicated that the positive expression of TGF-β1 in carcinomas was 71.21%, significantly higher compared to that in the normal cervix (35%) and chronic cervicitis (55%) (χ(2) = 8.901, P = 0.012). Similarly, the positive expression of ERα in the carcinomas was 68.18%, significantly higher compared to the normal cervix (35%) and chronic cervicitis (50%) (χ(2) = 7.693, P = 0.021). Both TGF-β1 and ERα in the carcinomas were associated with the vaginal recurrence, infection of HPV, depth of infiltration, and lymphatic metastasis (P < 0.05). The conjugation of TGF-β1 and ERα was an independent prognostic factor for cervical adenocarcinoma. Survival curve showed that the positive TGF-β1 and ERα indicated a short lifetime of patient with cervical adenocarcinoma. In conclusion, the expression of TGF-β1 and ERα protein in the carcinomas had a significant prognostic value in a patient of stage Ib~IIa in cervical adenocarcinoma.
