Abstract

Background/Aims: Surgical resection is not generally indicated for para-aortic lymph node (PALN) metastasis from colorectal cancer. However, the clinical significance of PALN dissection (PALND) in the current era of modern chemotherapy has not been fully discussed. Methods: Between November 2006 and February 2013, 14 patients underwent PALND for colorectal cancer and were proven as having pathological PALN metastasis. The median follow-up was 33.2 months. Results: Primary location was the right-colon in 2 patients, and the left-colon or rectum in 12 patients. The timing of metastasis was metachronous in 5 patients and synchronous in 9 patients. Eleven patients (79%) received perioperative aggressive modern chemotherapy. Neoadjuvant chemotherapy with targeted drugs was introduced in 9 patients (64%) and 6 patients received adjuvant chemotherapy. Recurrence after PALND occurred in 12 patients (86%). The most common site was the lung in 6 patients (43%). The 1-and 3-year disease-free survivals were 39.3 and 7.9%, respectively. The 3-year overall survival were 41.2%. Conclusion: The recurrence rate after PALND for strictly selected patients was quite high even in the current era of modern chemotherapy. However, some patients achieved long-term survival or could be cured. Therefore, we should re-evaluate the efficacy of PALND in a larger prospective study.
