Objective: The evaluation of 58 operated endometrial cancer patientsby means of diagnosis and treatment. Material and method: The cases were 58 endometrium cancer patients thet were diagnosed and treated in our clinic between January 2001 and February 2006. Results: The median age was 60.8 ± 13.2 (25-85 years of age). Considered to due to histopathologic subgroups, the most common was endometrioid adenocarcinoma with 45 cases (%77.7) followed by 5 cases of serous papillary carcinoma (%8.6), 7cases of mixed adenocarcinoma with clear cell component (%12) and 1 case of small cell carcinoma (%1.7). Surgical staging revealed the most common stage to be stage Ib1 (%38.3 of cases) and when patients screened for their grades,%60 (36) of cases found to be Grade II. The median endometrial tickness measured by transvaginal ultrasonograpy was 15.9 mm (5-36 mm). The estimated mean Ca 125 value was 92.6 U (4.4-1566). In the postoperative period,17 (%28.3) of cases were treated with adjuvant radiotherapy and 8 (%13.3) of them were treated with adjuvant chemotherapy. The medien follow up period was 15.6 ± 5.2 (1-43) months. Five (%8.3) of cases were died in follow up period. Conclusion: The prognosis of endometrium cancer patients vary due to the treatment, the histopathologic type,grade and the lvel of myometrial invasion.
