Pelvic Recurrence After Curative Resection for Rectal Adenocarcinoma: Impact of Surgery on Survival.

BACKGROUND/AIM: Rectal cancer (RC) represents 30% of colon cancers. Despite the progress achieved in integrated chemoradiotherapy and surgical multidisciplinary treatments, the rate of local recurrence (LR) is 3.7-13%. Multivisceral resections allow many patients with pelvic recurrence to be treated in a curative manner. The purpose of this work is to assess the impact of surgery for rectal cancer patients with pelvic recurrence. PATIENTS AND METHODS: In a retrospective study from 2013 to 2018, data was collected from patients who had undergone rectal resection for adenocarcinoma. We compared perioperative data, postoperative outcomes, oncological results, and survival rates. RESULTS: 106 rectal cancer patients (40-87 years old) requiring surgery were included. The local recurrence rate was 15% (15 patients). LR patients requiring intervention were nine (56%) who underwent sphincter sparing surgeries, and 6 (44%) who underwent surgeries with sphincter resection. There was no statistically significant difference (p=0.416) in the 5-year overall survival rate of patients without recurrence compared to those with pelvic recurrence. CONCLUSION: Curative surgery for local recurrence from rectal cancer is safe and feasible and should be considered in selected cases as it seems to provide acceptable surgical and oncological outcomes.
