Abstract

Colorectal cancer is a predominant source of cancer-related illness and
death worldwide. The study aimed to describe the demographic and
clinical factors associated with CRC. A cross sectional study was
conducted involving 74 cases of colorectal cancer patients. Analysis was
done on demographic factors such age, sex, employment, and place of
residence, we gathered clinical information from patients on their tumor
site, family history, chronic illnesses, cancer grade, stage, and lymph node
metastasis (LNM). Marked disparities were observed among colorectal
cancer patients in term of age distribution and occupation with the largest
proportion aged 41-50 years (31.08%). Tumor location was mainly on the
left side (51.35%) with a significant association (p < 0.01). One-third of
patients (33.78%) had a positive family history of colorectal cancer (p <
0.01). Chronic disease presence was higher in patients but not statistically
significant (p = 0.11). Most patients presented with grade 2 tumors
(78.38%) and stage T3 (78.38%) disease, with a high prevalence of lymph
node metastasis (70.27%) (p < 0.01 for all). Sex and residency showed no
significant differences between groups. The study highlights significant
demographic and clinical disparities among colorectal cancer patients
emphasizing the importance of age, occupation, tumor site, family history,
and disease stage in CRC risk and progression. These findings can inform
targeted screening and tailored treatment approaches.
