RESUMO
Endometrial cancer is the commonest gynecological cancer mostly affecting women in the postmenopausal age group. There is a debate regarding the need of pelvic lymphadenectomy in managing stage 1A diagnosed preoperatively, we try to evaluate this need. To evaluate the role of pelvic lymphadenectomy in stage 1A endometrial carcinoma diagnosed preoperatively by pelvic ultrasonography and CT scan as microscopic invasion of pelvic lymph nodes will not be seen by this imaging technique. 60 Cases of endometrial carcinoma diagnosed by fractional curettage and proved to be stage 1A preoperatively by clinical examination, vaginal US and CT scan [negative myometrial invasion, ascites, LN spread and local spread] underwent total abdominal hysterectomy with salpingo-oopherectomy, peritoneal wash for cytology, omentectomy and pelvic lymphadenectomy [external iliac and obturator groups] after written informed consent. Histopathology of the uterus, tubes, ovaries, omentum and cytology of peritoneal wash were done for surgical staging, in addition histopathology of pelvic LN was done. Histopathology of the cases revealed the following: 52 cases were endometrioid adenocarcinoma distributed as follows: 10 patients were grade I, 35 patients were grade 2 and 7 patients were grade 3. Eight cases were serous papillary adenocarcinoma, 3 of them were grade I and 5 cases were grade 2. As regards myornetrial invasion 9 cases of endonietrioid carcinoma show invasion, I of grade 1.3 of grade 2 and 5 of grade 3 in comparison to 4 cases of papillary serous adenocarcinoma I of grade I and 3 of grade 2, so 13 cases have been proved by histopathology to have myometrial invasion. There is no need for lymphadenectomy in stage 1A diagnosed preoperatively using CT scan and vaginal US, preventing high risk surgical intervention in this early stage
