Our goals were to examine the impact of neoadjuvant chemoradiation for rectal cancer on surgical outcomes and to determine prognostic factors predicting improved survival.
Retrospective cohort of 56 male and 44 female patients.
After preoperative chemoradiation, 73%of patients had sphincter-preserving surgery. The 5-year disease-free (DFS) and overall survival rates were 77%and 81%, respectively. Twenty-five percent of patients showed a complete pathologic response. T-level downstaging and pathologic T stage did not correlate with recurrence or survival rates. Pathologic nodal stage was associated with a significant difference in recurrence rates (N<sub>0sub> 19%, N<sub>1sub> 20%, and N<sub>2sub> 75%, P = .038) and DFS (N<sub>0sub>/N<sub>1sub> vs. N<sub>2sub>, 79%vs. 25%, P = .002).
Neoadjuvant chemoradiation resulted in a high rate of sphincter preservation. Complete pathologic responses after surgery were frequent and although pathologic T stage after surgery did not affect recurrence rates, pathologic nodal response was associated with improved recurrence and survival rates.
