Incidental perforation in rectal cancer surgery is considered a risk factor for poorer oncological outcome. Most studies emanate from the era before total mesorectal excision when staging, neoadjuvant treatment and surgical technique were suboptimal. This study assessed the impact of incidental perforation on oncological outcome in a cohort of patients with optimized management. ⋯ Incidental perforation remains a significant risk factor for LR, even with optimized management of rectal cancer. This must be considered when discussing adjuvant treatment and follow-up.

Multicenter Study Clinical Trial
Residual disease after neoadjuvant chemoradiotherapy for oesophageal cancer: locations undetected by endoscopic biopsies in the preSANO trial.
Active surveillance has been proposed for patients with oesophageal cancer in whom there is a complete clinical response after neoadjuvant chemoradiotherapy (nCRT). However, endoscopic biopsies have limited negative predictive value in detecting residual disease. This study determined the location of residual tumour following surgery to improve surveillance and endoscopic strategies. ⋯ Most residual disease after nCRT missed by endoscopic biopsies was located in the mucosa. Active surveillance could be improved by more sampling and considering submucosal biopsies.
