Authors' objectives: Background In patients with advanced rectal cancer, chemoradiotherapy is an established treatment to achieve tumour down staging/downsizing prior to surgery and to lower the risk of local recurrence. Approximately 10% of patients have complete clinical response (cCR), i.e. no detectable tumour, after treatment with chemoradiotherapy. For this group of patients a “watch and wait” strategy (W&W) without early resection has been suggested. Rectal resection is associated with significant perioperative risks and complications but also long-term impaired quality of life by altered bowel function. Objective To study if it is possible to avoid surgery without compromising disease-free survival in adult patients with rectal cancer planned for curative resection who have had a clinical complete response after initial chemoradiotherapy.
Authors' results and conclusions: There are only few non-randomised studies including a total of approximately 600 patients of a “watch and wait” strategy compared with surgery in patients with rectal cancer with cCR after chemoradiotherapy. In the studies, survival and the frequency of distant metastasis did not differ while there were more local recurrences and less major complications after “watch and wait”, but the certainty of evidence is very low for all outcomes. More studies, particularly on the outcome HRQoL and with adequate follow-up, are needed.
