OBJECTIVE: The incidence of carcinoma of endometrium in younger patients has increased tendency. Experimental data support that mutation of tumor suppressor gene TP53 plays an important role in endometrial carcinogenesis
MATERIAL AND METHODS: Exons 2-11 of the gene TP53 into tissues of endometrial carcinoma and precancerous lesions were analyzed by DNA sequencing and restriction analysis.
RESULTS: A polymorphism CCC/CGC at codon 72 was identified in exon 4 of TP53 gene of all precancerous lesions and carcinomas of endometrium.
CONCLUSION: Our results also suggest presence of endometrial glandular dysplasia or serous histological type of endometrial carcinoma into examined samples. Given the course and prognosis of serous endometrial carcinoma, it is necessary and useful to identify this type of cancer in the mixed types of endometrial carcinomas. DNA analysis has potential to make diagnostic process more specific and affect to adjuvant therapy and survival of patients.
