Abstract
OBJECTIVE: Debulking surgery for advanced ovarian cancer does not routinely include opening of the thorax. Even systematic lymphadenectomy does not commonly extend to lymph nodes above the diaphragm. We evaluated the outcome of systematic resection of suspicious cardiophrenic lymph nodes detected on preoperative CT-scan in patients with advanced epithelial ovarian cancer (EOC). METHODS: Single-center, prospective series of 196 consecutive patients with EOC undergoing primary debulking surgery between June 2013 and June 2015. Suspicious cardiophrenic lymph nodes were defined as ≥10mm on the short axis diagnosed in pre-operative CT-scan and were removed if intra-abdominal debulking resulted in complete resection or residual tumor <10mm and the patients' performance status allowed this additional procedure. Removal of suspicious cardiophrenic lymph nodes was performed via a trans-diaphragmatic approach. RESULTS: Thirty (15%) out of 196 EOC patients had radiologically suspicious cardiophrenic lymph nodes ≥10mm and complete resection or residual tumor <10mm. Twenty-seven out of the thirty patients had at least one confirmed metastatic cardiophrenic lymph node. Metastatic cardiophrenic lymph nodes were associated with extensive intra-abdominal tumor spread in the upper abdomen. CONCLUSIONS: Patients with suspicious cardiophrenic lymph nodes detected by preoperative CT-scan had histologically confirmed metastasis in 90% of cases. The surgical procedure is feasible without major complications if performed by experienced gyneco-oncologists. The prognostic value of this procedure should be evaluated in larger controlled studies.
