Abstract
Previous reviews and meta-analyses, which predominantly focused on patients treated before 2000, have reported conflicting evidence about the association between hospital/surgeon volume and rectal cancer outcomes. Given advances in rectal cancer resection, such as total mesorectal excision, it is essential to determine whether volume plays a role in rectal cancer outcomes among patients treated since 2000.
The purpose of this study was to determine whether there is an association between hospital/surgeon volume and rectal cancer surgery outcomes among patients treated since 2000.
We searched PubMed and EMBASE for articles published between January 2000 and December 29, 2017.
Articles that analyzed the association between hospital/surgeon volume and rectal cancer outcomes were selected.
Rectal cancer resection was the study intervention.
The outcome measures of this study were surgical morbidity, postoperative mortality, surgical margin positivity, permanent colostomy rates, recurrence, and overall survival.
Although 2845 articles were retrieved and assessed by the search strategy, 21 met the inclusion and exclusion criteria. There was a significant protective association between higher hospital volume and surgical morbidity (OR = 0.80 (95% CI, 0.70-0.93); I = 35%), permanent colostomy (OR = 0.51 (95% CI, 0.29-0.92); I = 34%), and postoperative mortality (OR = 0.62 (95% CI, 0.43-0.88); I = 34%), and overall survival (OR = 0.99 (95% CI, 0.98-1.00); I = 3%). Stratified analysis showed that the magnitude of association between hospital volume and rectal cancer surgery outcomes was stronger in the United States compared with other countries. Surgeon volume was not significantly associated with overall survival. The articles included in this analysis were high quality according to the Newcastle-Ottawa scale. Funnel plots suggested that the potential for publication bias was low.
Some articles included rectosigmoid cancers.
Among patients diagnosed since 2000, higher hospital volume has had a significant protective effect on rectal cancer surgery outcomes.
