OBJECTIVES: A relatively high incidence of para-aortic and pelvic lymph node metastasis is found in epithelial ovarian cancer. This paper investigates the clinicomorphological features of intra-abdominal stage I epithelial ovarian cancer that may predict the occurrence of lymph node metastasis and the prognosis of patients in whom lymph node metastases are identified. METHODS: From November 1988 to December 1997 we performed systematic para-aortic and pelvic lymphadenectomy as primary surgery in 47 patients with intra-abdominal stage I epithelial ovarian cancer. The incidence of lymph node metastasis in these patients and the clinicomorphological features of the patients with lymph node involvement were examined. RESULTS: Five patients (10.6%) were metastasis positive (IC: four; IA: one), of whom four had serous adenocarcinoma. Serous adenocarcinoma was associated with a significantly higher incidence of metastases than other histological types (P < 0.05). The number of positive lymph nodes was one in four patients and two in one patient, and the metastatic sites ranged from the para-aortic to the suprainguinal lymph nodes. All five metastasis-positive patients were alive and disease free at the time of this report (survival 28-85 months: median 59 months). CONCLUSION: This clinical study suggests that serous adenocarcinoma carries a high risk of lymph node metastasis, requiring systematic lymphadenectomy for accurate staging in intra-abdominal stage I epithelial ovarian cancer.
