[The place of lumo-aortic and pelvic lymph node dissection in the treatment of ovarian cancer]. / Place du curage lombo-aortique et pelvien dans les cancers épithéliaux de l'ovaire.

Ovarian cancer often invades regional lymph nodes but the patterns of involvement are variable; spread to para-aortic and pelvic lymph nodes can be unilateral, contralateral or bilateral. For staging purposes, complete lymph node dissection seems more reasonable and effective than simple lymph node sampling. In early stage disease, lymph node dissection has both diagnostic and therapeutic value allowing identification and optimal management of Stage IIIc tumors with retroperitoneal spread; it may also have direct therapeutic value by removing retroperitoneal micrometastatic disease including cell clones which may be resistant to chemotherapy. Therefore, complete lymph node dissection is recommended in early-stage disease with the exception of stage I mucinous ovarian cancer. In advanced-stage disease, lymph node involvement is an additional factor of poor prognosis correlating with increased tumor aggressivity. Optimal debulking resection of all visible tumor offers the best chance for a prolonged disease-free interval if patient condition permits and morbidity can be limited. Survival benefit for complete lymph node dissection has not been evaluated by randomized controlled trials; but several non-randomized studies and two long-term prospective trials have shown objective improvement in disease-free survival and improved quality of life when debulking surgery leaves no residual tumor larger than 1 cm.
