Abstract
BACKGROUND
World-wide Colorectal cancer (CRC) is the third most common cancer with one million new cases a year. Historically, a higher incidence of this disease has been recorded among the elderly in the western countries, but it is increasing in developing countries and in younger age groups.
AIM
This study aims to find whether CRC cancer is progressively affecting the younger age groups known as early onset (< 50 years). In addition, it describes the pathological characteristics of CRC in early onset CRC cases.
METHOD
The study is retrospective cross-sectional. It was conducted over a period of five months from October 1st 2019 till 1st March 1st 2020. Data were drawn from patients with CRC from their medical records at Kirkuk Oncology Centre (KOC) and from the IRAQI National CANCER REGISTRY (INCR) over thirteen years period from 2006 to 2018. The basic data we obtained for each patient include sex, age, and stage, grade of the disease at diagnosis and mode of presentation.
RESULTS
The Initial study population included 654 patients of both genders and all ages. CRC occurred in < 5.5/100,000 population per year which accounted for < 8% of total malignancies (2006-2018). The patients were divided into two groups; an early onset (< 50 years) group and a late onset CRC (⩾ 50 years) group. The final study population provided enough data for 238 patients for the years (2014-2018) with an age range of 20-91 and a mean of 54.4 years. The males were ∼54% while ∼46% were females. The age group under 50 years (early onset CRC) was ∼41% (no 98) while those who are 50 years and older (late onset) stood for 59% (no 140). There were no statistical differences between the two age groups regarding stage, grade, or presenting symptom.
CONCLUSION
CRC is common in early onsets or young age groups with similar pathological characteristics to those of the late onset cancer. Accordingly, even mild lower gastrointestinal symptoms should be taken seriously. The study points toward an increasing awareness of the population on the importance of colorectal cancer. Also, conducting more surveillance studies and investigations would be recommended for early detections of the disease in young populations.
