However the extent of lymphadenectomy in the early stages of ovarian cancer is controversial. The objective of this study was to identify the lymph node involvement in unilateral epithelial ovarian cancer apparently confined to the one ovary clinical stage Ia . Methods A prospective study of clinical stage I ovarian cancer patients is presented. Patient s characteristics and tumor histopathology were the variables evaluated. Results Thirty three ovarian cancer patients with intact ovarian capsule were evaluated. Intraoperatively neither of the patients had surface involvement adhesions ascites or palpable lymph nodes supposed to be clinical stage Ia . The mean age of the study group was . All patients were surgically staged and have undergone a systematic pelvic and paraaortic lymphadenectomy. Final surgicopathologic reports revealed capsular involvement in seven patients contralateral ovarian involvement in two 6 and omental metastasis in one 3 patient. There were two patients 6 with lymph node involvement. One of the two lymph node metastasis was solely in paraaortic node and the other metastasis was in ipsilateral pelvic lymph node. Ovarian capsule was intact in all of the patients with lymph node involvement and the tumor was grade 3. Conclusion In clinical stage Ia ovarian cancer patients there may be a risk of paraaortic and pelvic lymph node metastasis. Further studies with larger sample size are needed for an exact conclusion. Background Epithelial ovarian carcinoma EOC is a lethal .
