INTRODUCTION: Young individuals with colorectal cancer (CRC) tend to be diagnosed at advanced stages and are not routinely included in screening programmes. This study describes the incidence, disease pattern and factors affecting overall survival in young-onset CRC. METHODS: A retrospective study of young-onset CRC patients diagnosed between 2010 and 2017 in a tertiary hospital was conducted. RESULTS: There were 99 patients, 69.7% had left-sided while 30.3% had right-sided CRC. The mean age was 43.3 years (43.3±5.0) and 62 patients (62.6%) were male. The incidence of young-onset CRC has been on the rise since 2014. Out of 99 patients, 65 (65.7%) underwent elective surgery, 30 (30.3%) underwent emergency surgery and the remainder 5 (4.0%) were palliated. The most common presenting complaints for patients who underwent elective surgery were abdominal pain, per-rectal bleeding and altered bowel habits. For patients who required emergency surgery, 20 (66.6%) presented with intestinal obstruction and 10 (33.3%) had intestinal perforation. There were 42 (42.4%) stage III CRC and 20 (20.2%) stage IV CRC. The most frequent metastatic site was the liver (20/20, 100%). Five patients had signet ring cells (5.1%) in their histology while 15 (15.2%) had mucinous features. The overall 5-year survival of young-onset CRC was 82.0%. Advanced overall stage (hazard ratio (HR) 6.1, CI 1.03-3.62) and signet ring histology (HR 34.2, CI 2.24-5.23) were associated with poor prognosis. CONCLUSION Young-onset CRC tend to be left-sided with advanced presentations. However, their 5-year survival remains favourable as compared to the general population.
