Influence of non-clinical factors on restorative rectal cancer surgery: An analysis of four specialized population-based digestive cancer registries in France.

Abstract

BACKGROUND\nThis study aims to measure the association between deprivation, health care accessibility and health care system with the likelihood of receiving non-restorative rectal cancer surgery (NRRCS).\n\n\nMETHODS\nAll adult patients who had rectal resection for invasive adenocarcinoma diagnosed between 2007 and 2016 in four French specialised cancer registries were included. A multilevel logistic regression with random effect was used to assess the link between patient and health care structure characteristics on the probability of NRRCS.\n\n\nRESULTS\n2997 patients underwent rectal cancer resection in 68 health care structures: 708 (23.63%) had NRRCS. The likelihood of receiving NRCCS was associated with patients characteristics (97%): age, sub peritoneal rectal tumors, neoadjuvant therapy, residual tumour and stage III . There was no impact of European Deprivation Index or remoteness on NRRCS. Inter-health care structure variability was modest (3%), of which 50% was explained by the high group volume of colorectal procedures and the type of health care structure which were associated with less NRRCS (p<0.01).\n\n\nCONCLUSION\nThere is an influence of operating volume and type of structure on the probability of NRRCS, but it has truly little importance in explaining differences in performances. The probability of NRRCS is mainly affected by clinical determinant.
