Many factors can affect prognosis of this type of cancer, these mainly are the degree of myometrial invasion by the tumour, pelvic and paraaortic lymph node spread as well as the tumour histological type (endometrioid vs non-endometrioid type). transvaginal ultrasound (TVS) is a highly accurate and easy method for preoperative evaluation of myometrial invasion. Aim of the Work: The aim of this work is to assess if there is relation between the depth of myometrial invasion by the tumor and the rate of lymph node involvement in cases of endometrial cancer. Results: It was found that there was a significant relation between lymph node affection and the depth of myometrial invasion, all the positive lymph node affections cases had myomterial invasion > 50.0%. Conclusion: The incidence of pelvic lymph node affection is very high in cases where the myometrium is deeply infiltrated with the tumor. Assessment of myometrial invasion preoperatively by TVU and microscopically by pathological examination of the myometrium after hysterectomy provides an accurate estimation of the rate of pelvic lymph node affection and hence necessitates lymphadenectomy procedures in cases where myometrium is deeply infiltrated by the tumor and omitted in cases where it is tumor free. %K Endometrial Cancer %K Endometrial Carcinoma %K Lymph Node Affection %K Myometrial Invasion %U http://www.scirp.org/journal/PaperInformation.aspx?PaperID=108512
