ABSTRACT: Introduction: Endometrial cancer is the fourth most frequent cancer in females. 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.
