Surgical staging of endometrial cancer includes a hysterectomy, bilateral salpingo-oophorectomy, and evaluation of regional LN involvement, specifically the pelvic and aortic lymph node. Sentinel lymphadenectomy has been suggested in the staging process of the diseases. The aim of this study was to compare the role SLN mapping over total lymphadenectomy for detection of disease metastasis in cases of cancer of the endometrium Method: 30 patients that were diagnosed of having endometrial cancer . were included in this stud and were divided in to two equal groups and mapping was done to 15 patients and all patient had undergone lymphadenectomy Results: In this study The mean age of patients was 55 years ( range 45-74) for group 1 and was 56ys ( range 43-75) for group2. Also the increase in weight as BMI, Median (Range) was 35 (26-45) for group 1 and for group2 was 34 (28-50). The postoperative results had shown some changes as about ( 60%) of patients were of grade 1 and about (33.3%) of patients were of grade 2 and about ( of patients were of grade 3 this was for group1 while for group 2 about (66.7)of patients were of grade 1 and about ( 20%)of patients were of grade 2 while about ( 13.3)of patients were of grade 3 we approved that proved that SLN biopsy has relatively equal values like lymphadenectomy in staging of endometrial cancer with sensitivity 80% and specificity 90%. Sentinel mapping had good sensitivity and specificity diagnostic potentials.
