Background and objectives: Isolated paraaortic lymph-node recurrence (IPLR) after curative surgery for colorectal carcinoma is rare and no previous report has specifically addressed this type of recurrence. We investigated the clinical features of IPLR and analyzed prognostic factors. Methods: Of 2,916 patients who underwent curative surgery for colorectal carcinoma, IPLR was identified in 38 patients (1.3%). The clinical features and prognostic factors of these patients were analyzed. Results: IPLR was first detected by increased serum carcinoembryonic antigen (CEA) levels (63.2%) or by routine follow-up computed tomography (CT) (36.8%). Curative resection of IPLR was performed in six patients (15.8%). A total of 19 patients (50.0%) received chemoradiation therapy and 13 patients (34.2%) received chemotherapy only. The median survival from IPLR was 13 months (range: 5-60 months). The median survival time from IPLR for the resected patients was 34 months, whereas it was 12 months for those who did not undergo resection (P = 0.034). The factors associated with the prognosis were histological grade (P = 0.003), location (P = 0.032), and resection of IPLR (P = 0.034). Conclusions: IPLR after curative surgery for colorectal carcinoma is rare. Although it is generally associated with poor prognosis, better survival might be achieved through curative resection in selected cases.
