Résumé
Rectal cancer surgery conveys significant morbidity/mortality, long-term functional impairment and urinary & sexual dysfunction, especially if associated with neoadjuvant chemoradiotherapy (ChRT). Watch & Wait (W&W) is gaining momentum as an option for patients with clinical complete response (cCR) after ChRT. Approximately 30% will develop a local regrowth (RG) and need deferred surgery. Our study aimed to assess the short-term clinical outcomes after surgery for regrowths. Consecutive rectal cancer patients from a tertiary institution who underwent neoadjuvant ChRT, between January 2013 and October 2018, were identified from a prospectively maintained database. Patients with RG under W&W surveillance were operated - regrowth deferred surgery (RDS) group - and compared to those with persistent disease after ChRT who did undergo surgery - non-deferred surgery (NDS) group. Total of 124 patients received neoadjuvant treatment: 46 (37%) underwent surgery for persistent disease; 78 (63%) with cCR entered W&W. Twenty three developed RG and underwent surgery, while 55 remain under surveillance. RDS group had lower tumors than NDS group (2.3 cm ± 2 vs 4.5 cm ± 3, p = 0.002). All RG underwent minimally invasive surgery (MIS). Anastomotic leaks, 30-day morbidity, reintervention and readmission rates were similar. Pathology features and 3-year oncological outcomes were identical between groups. Patients with initial cCR and local regrowth may be safely managed by deferred surgery. Short-term outcomes suggest equivalent results to patients with incomplete clinical response and immediate radical surgery. Delayed MIS appears to have no negative impact on oncological outcomes.

BACKGROUND
BACKGROUND
Rectal cancer surgery conveys significant morbidity/mortality, long-term functional impairment and urinary & sexual dysfunction, especially if associated with neoadjuvant chemoradiotherapy (ChRT). Watch & Wait (W&W) is gaining momentum as an option for patients with clinical complete response (cCR) after ChRT. Approximately 30% will develop a local regrowth (RG) and need deferred surgery. Our study aimed to assess the short-term clinical outcomes after surgery for regrowths.
PATIENTS AND METHODS
METHODS
Consecutive rectal cancer patients from a tertiary institution who underwent neoadjuvant ChRT, between January 2013 and October 2018, were identified from a prospectively maintained database. Patients with RG under W&W surveillance were operated - regrowth deferred surgery (RDS) group - and compared to those with persistent disease after ChRT who did undergo surgery - non-deferred surgery (NDS) group.
RESULTS
RESULTS
Total of 124 patients received neoadjuvant treatment: 46 (37%) underwent surgery for persistent disease; 78 (63%) with cCR entered W&W. Twenty three developed RG and underwent surgery, while 55 remain under surveillance. RDS group had lower tumors than NDS group (2.3 cm ± 2 vs 4.5 cm ± 3, p = 0.002). All RG underwent minimally invasive surgery (MIS). Anastomotic leaks, 30-day morbidity, reintervention and readmission rates were similar. Pathology features and 3-year oncological outcomes were identical between groups.
CONCLUSION
CONCLUSIONS
Patients with initial cCR and local regrowth may be safely managed by deferred surgery. Short-term outcomes suggest equivalent results to patients with incomplete clinical response and immediate radical surgery. Delayed MIS appears to have no negative impact on oncological outcomes.
