The Clinical Analysis of Endometrial Cancer by Surgical Staging

Abstract

In 1988, the International Federatioa of Gynecology and Obstetrics(FIGO) Cancer Committee changed the staging of endometrial carcinoma from a clinical one to a surgicopathologic one. The emphasis in the new FIGO system was changed to the pathologic findings in the uterus, cervix, adnexae, and pelvic and/or periaortic nodes, and peritoneal cytologic findings. The major changes in this staging system were the use of the depth of myometrial invasion and the identification of tumor cells in peritoneal cytologic examination and of invasion in the retroperitoneal lymph nodes, Preoperative endocervical curettage was no longer necessary. This is a reflection of the increase in the primary surgical approach to the treatment of this disease and has allowed the identification of a number of prognostic factors on which postoperative therapy can be based. This retrospective study was based on a clinical review of 45 patients with endometrial carcinoma from Jan, 1985 through Jan, 1996 who underwent primary surgical evaluation at the Department of Obstetrics and Gynecology, Kyungpook National University Medical College. The results obtained are as follows; l. Age distribution of endometrial cancer was concentrated on the age group of 50-59(55.6%) and mean age was 53.9 years. 2. The mean parity and mean BMI(Body Mass Index) of endometrial cancer were 3.8 and 25.0(cm/kg2). 3. The Menstrual status at the time of development of endometrial cancer showed that 24 cases (53.3%) were postmenopausal, 11 cases (24.4%) were premenopausal and 10 cases(22.2%) were menstruating. 4. According to the clinical stage adopted by FIGO classification, stage I was found in 71.1%, stage II in 17.8%, stage III in 2,2%, stage IV in 0.0%. 5. Surgical restaging according to new FIGO classification(1988), stage IA was found in 4.4%, stage IB in 37.8%, stage IC in 28.9%, stage IIA in 0.0%, stage IIB in 0.0%, stage IIIA in 6.7%, stage IIIB in 4.4%, stage IIIC in 8.9%, stage IVA in 2.2% and IVB in 6.7%. 6. According to WHO histopathological classification, the percentage of the adenocarcinoma was 86.7%, adenoacanthoma 4.4%, papillary serous adenocarcinoma 2.2%, and adenosquamous cell carcinoma 6.7%. 7, The relationship between histologic grade and depth of invasion was somewhat correlated but no staistical significance. 8. There was no correlation between BMI(Body Mass Index) and histologic grade, depth of invasion. 9. Surgery upstaged 15.6% of clinical stage I patients and 62,5% of clinical stage II, but 37.5% of clinical stage II patients was downstaged. 10. All cases were primarily treated by surgery. Regarding the types of operation, total abdominal hysterectomy with bilateral salpingoophorectomy was performed in 44.4%, radical hysterectomy with both pelvic lymphadnectomy in 42.2%, total abdominal hysterectomy with bilateral salpingoophorectomy with selective pelvic lymph node dissection in 8.9%, and laparoscopic assisted vaginal hysterectomy in 2.2%. 11. The mean follow up interval was 38.6 months. 28 cases were followed up and 10 cases of surgical stage I revealed over 5 year salvage. 5-year survivals for surgical stage IA, IB, IC, III, and IV were 100, 100, 92.3, 88.9, and 100%, respectively.
