Colorectal cancer in the young - outcomes following surgical management?

introductionColorectal cancer (CRC) is the third most common cancer, accounting for approximately 10% of all cancer deaths. The incidence of CRC in young adults and the adolescent population is increasing. This study aims to highlight short-term outcomes for young patients with CRC.

methodsData were collected retrospectively for all patients aged less than 50 years diagnosed with CRC at a university teaching hospital between October 2012 and June 2018. The primary endpoints were disease-free survival (DFS) and overall survival (OS).

resultsA total of 120 patients (65 males, 55 females) with CRC aged under 50 years were initially included; 20 did not receive surgical treatment (12 metastatic adenocarcinoma, 5 metastatic squamous cell cancer (SCC), 3 neuroendocrine tumours (NET)), and 13 patients had insufficient data for analysis and were excluded. A total of 87 patients underwent surgical intervention and 66 with diagnosis of adenocarcinoma were included in survival analysis. Median age of patients was 42 years (19-49 years). Cancer recurrence was seen in 14 patients, 10 showing local, 3 liver and 1 lung metastasis. The median OS was 28 months (3-156 months). The median DFS was 13 months (3-85 months). Overall 5-year survival and DFS were 72% and 59%, respectively. Median survival in the group who did not undergo surgery was 4.5 months (1-15 months).

conclusionsCRC is often more advanced and aggressive in younger patients. Current guidelines can result in young patients being investigated/treated for other gastrointestinal conditions before referral for CRC investigation.
