Evaluation of clinical parameters, MDM2 gene expression, P53, C-ERBB-2 and Kİ-67 expressionin developmentand prognosis of gestational trophoblastic disease

Purpose: To evaluate the mdm2 gene expression, p53 expression, c-erbB-2 expression, Ki-67 expression and and clinical parameters in the formation and prognosis of the gestational trophoblastic disease.Materials and Methods: Eighty-one participants living in the Cukurova region who have attended the Cukurova University, Medical Faculty, Department of Obstetrics and Gynecology, Gynecologic Oncology Division between January 1997 and August 2009 and diagnosed and treated as gestational trophoblastic disease with twenty-three control patients were enrolled in this case control study. The patients were analyzed in between case and control groups, and in between the case subgroups. Analyzed parameters were the mdm2 gene expression, p53 expression, c-erbB-2 expression, Ki-67 expression, age gravida, parity, abortus, cigarette smoking, infertility history, blood types and beta-hCG.Results: There was statistical significant difference at the p53 expression and parity parameters between the case and control groups, the results were similar. For the rest of the paramaters, when the case group was subgrouped into good prognostic patients and poor prognostic patients, the levels of mdm2 expression, p53 expression, c-erbB-2 expression and beta-hCG were statistically significant whereas the other parameters remained similar in between the subgroups.Conclusion: p53 expression and parity were the parameters effecting the formation of the gestational trophoblastic disease which had diagnostic significance. mdm2 gene expression, p53 expression, c-erbB-2 expression and beta-hCG levels were found to be statistically significant in the development of the poor prognostic disease. The other parameters which were analyzed did not have a relationship with the formation and prognosis of the gestational trophoblastic disease.Key words: gestational trophoblastic disease, mdm2, p53, c-erbB-2, Ki-67, beta-hCG.
