Survival following curative surgery for colorectal cancer (CRC) in the middle-aged population: data from a South Asian cohort
(Springer, 2021) Vishwajith, P.; Chandrasinghe, P.; Gunasekare, K.; Gajasinghe, S.; Kumarage, S.
BACKGROUND/AIM : Colorectal cancer (CRC) is the fourth commonest cancer in Sri Lanka. Disease burden and survival among the middleaged population (50–70 years) with CRC is less studied. With the aging global population, this cohort has a high economic and a social impact. This study aims to analyse the survival pattern and contributing factors in a middle-aged patient cohort with CRC. METHODS: CRC patients managed with a curative intent between 1997 and 2020 at a specialised tertiary care unit were analysed. Demographic data, tumour characteristics and survival of the patients aged between 50 and 70 years was analyzed. Overall survival was compared with the younger (\50 years) and older ([70 years) populations with CRC using Kaplan–Meire curves. Individual variable analysis was performed to sought for significant association of survival with age, sex, tumour stage and tumour site. Multifactorial analysis was performed using Cox-proportional hazard model. RESULTS: A total of 411 patients between 50 and 70 years age group with CRC were analysed (mean 60.07 years; range—50–70 years, male—47.45%). Overall survival of the middle-aged population was significantly better (mean— 133 months, SE 6.84) compared to the elderly population (mean—58 month, SE = 7.74) but worse compare to the younger population (mean—167 month, SE = 10.81). Majority of the tumours (60.5%) in the middle-aged group were locally advanced on presentation ([T3). Tumor site and age at presentation were significant factors that influence survival in this age group. CONCLUSION: Middle-aged patients have a better mean overall survival than their older counterparts but fare worse compared to the younger age group. Tumor stage and age were the only factor that significantly influenced survival
Survival pattern and clinicopathological data from a South Asian cohort of young colorectal cancers treated with curative intent

BACKGROUND/AIM :Colorectal cancer (CRC) has the fourth highest incidence among cancers in Sri Lanka. Although CRC is considered as a disease of the elderly, currently there is a shift towards an increasing incidence of young cancers globally. Despite the increasing incidence there is a scarcity of data from the South Asian region. This study aims to analyze the clinicopathological features and long term survival of young CRC from a South Asian cohort of patients. METHODS: All patients treated for CRC at a tertiary care center from 1997 to 2017 were prospectively followed up. Demographics, tumour characteristics and survival data were recorded. Age less than 45 years at diagnosis was considered as a young cancer. Overall survival among the populations was compared using Kaplan-Mire survival curves. A P value of\0.05 was considered significant. Results: A total of 113 (16.5%) young cancers (Mean age 36.35; range 17–45; female 53.1%) were operated during the period. Rectum (60.2%) was the commonest site followed by the right colon (24.8%) and left colonic (15%) tumors. Adenocarcinomas of moderately differentiated variety (72.4%) was the commonest histological type. Seventy percent of cases had locally advanced disease (T3/T4) with 53.2% having positive nodal status. Of the total 27% received neoadjuvant treatment and 66.7% received adjuvant treatment. Young CRC patients had a significantly better overall survival compared to their older counterparts (P = 0.008). CONCLUSION Young cancers accounts for a significant proportion of the colorectal cancers in this cohort. Over 75% of the cancers were on the left colon and the majority was locally advanced disease. Overall survival of the young CRCs were better compared to the older population in this cohort.
