Abstract

Background: Recent studies have shown that poor survival for patientswith early endometrial cancer was related to the extrapelvic spread of the cancer. The purpose of this study was to evaluate the correlation between para-aortic lymph node (PAN) metastasis and histopathologic findings and to assess the clinical utility of identifying PAN metastasis of endometrial carcinoma. Methods: The correlation of para-aortic lymph node metastasis to the clinical stages of endometrial carcinoma (FIGO, 1982), histopathologic findings, and prognosis were investigated in 200 patients with endometrial carcinoma, who were treated by radical operations, including systematic retroperitoneal lymphadenectomies, between July 1982 and February 1996. Results: Of these, para-aortic lymph node (PAN) metastasis was seen in 18 (9.0%) and pelvic lymph node (PLN) metastasis in 40 (20.0%). The incidence of PAN metastasis according to clinical stages Ia, Ib, II, and III were 2.5%, 8.5%, 15.7%, and 33.3%, respectively. The incidence of metastasis was significantly higher in stage II than in stage Ia (P < 0.05), and in stage III than in stage Ia (P < 0.01). PAN metastasis occurred significantly more frequently in the first of each of the following groups: invasion of >1/2Of the myometrium (15.7%) vs. invasion of <1/2 of the myometrium (3.6%) (P < 0.01), the group with cervical invasion (23.5%) vs. the group without (4.0%) (P < 0.0001), the group with lymph-vascular space involvement (17.2%) vs. the group without (1.0%) (P < 0.0005), and PLN-metastasis-positive group (40.0%) vs. the negative group (1.3%) (P < 0.0001). Multivariate analysis showed a significant correlation between PANand PLN metastases (P < 0.0005). Positive PAN metastasis is not related to multiple PLN metastasis (bilateral PLN metastasis and the numberof PLN metastatic groups). However, a correlation was seen between PAN metastasis and common iliac node metastasis. The prognosis was significantly poorer (P < 0.05) for patients with both PLN and PAN metastases than for those with PLN metastasis alone. Conclusions: The results of the present study suggest that PAN metastasis may occur as a consequence of PLN metastasis or the two may occur simultaneously as PLN metastasis and also that careful examination of PAN metastasis is necessary to determine the prognosis.
