Multicenter Study
Indication and benefit of pelvic sidewall dissection for rectal cancer.
This study was designed to clarify indication and benefit of pelvic sidewall dissection for rectal cancer. ⋯ Positive lateral lymph node was the strongest predictor in both survival and local recurrence. Pelvic sidewall dissection may be indicated for patients with T3-T4 lower rectal cancers because of the greater probability of positive lateral lymph nodes.
