Meta Analysis
Complete pathologic response after combined modality treatment for rectal cancer and long-term survival: a meta-analysis.
Complete pathologic response (CPR) after neoadjuvant chemoradiotherapy (combined modality treatment, CMT) for rectal cancer seems associated with improved survival compared to partial or no response (NPR). However, previous reports have been limited by small sample size and single-institution design. ⋯ CPR after CMT for rectal cancer is associated with improved local and distal control as well as better OS and DFS.
