Abstract
Up to 30% of patients with colorectal cancer present as an emergency and have worse outcomes than elective patients. Compared with left-sided cancers, malignancies arising in the right colon are significantly under-researched. We sought to compare cancer care quality and clinical outcomes between emergency and elective presentations of right-sided colon cancer (RCC). This multicentre, retrospective study included all patients who underwent operative management for a RCC, from 1 April 2017 to 31 March 2022. Data were collected from electronic patient records, and host and tumour factors as well as outcomes between emergency and elective cohorts were compared. Overall, 806 patients (median age 72 years) were included. Some 175 patients (22%) presented as an emergency: 140 in obstruction and 35 with tumour perforation, compared with 1 patient with tumour perforation in the elective group (p < 0.001). The emergency group had higher rates of postoperative complications (59.1% vs 20.0%, p < 0.001), increased 90-day mortality (13.7% vs 1.3%, p < 0.001) and a longer hospital stay (5 vs 10 days, p < 0.001). From the emergency cohort only 29.2% of eligible patients received adjuvant chemotherapy and in multivariate regression analysis emergency presentation was associated with a decreased likelihood of receiving adjuvant chemotherapy (odds ratio 0.26 [0.14-0.47], p < 0.001). Both short- and long-term outcomes after emergency presentation of RCC are poor, with inadequate access to subsequent chemotherapy. Strategies addressing emergency presentations of left-sided tumours have moved towards temporisation and elective surgery. Delaying major resectional surgery for optimisation may improve outcomes and access to adjuvant therapies for RCC.
