Multiple Associations of Clinicopathological Characteristics and Risk Factors of Colorectal Cancer in the Iranian Population
Background: Previous studies have demonstrated that clinicopathological features of colorectal cancer (CRC) could be diverse in different CRC patients groups. The present study aimed to analyze the association between clinicopathological characteristics and the risk factors in different CRC patients groups, which is categorized by sex, family history, age, and also primary tumor site in the Iranian CRC patients.
Method: In this cross-sectional study, we included 304 patients with CRC. The data of clinicopathological features were collected from documented pathology reports. Subsequently, we carried out multiple analyses to discover the association among these elements.
Results: Our analysis demonstrated that there was a significant difference between men and women regarding the mean age at diagnosis, tumor locations, mean size of tumors, positive family history, smoking status, and physical activity (P <0.05). Out of all the patients, 22.4% had a positive family history of cancer. The patients with a positive family history just have lower mean age, body mass index (BMI), and higher physical activity compared with patients without family history of cancer (P <0.001). 31.9% of the patients were in the age group of below 55 and 68.1% were in the age group of 55. The majority of our patients in 0.05).
Conclusion: Gaining information about the association between clinicopathological characteristics and the risk factors in CRC could provide a better understanding of disease pathogenesis and consequently, improve the management of diseases
Environmental Risk Factors Associated with Sporadic Colorectal Cancer in Isfahan, Iran
Background: Records from the cancer registry system of Iran indicate that
colorectal cancer is the third most common cancer in Iranian men and fourth most
common among Iranian women. In this study we have investigated the environmental
factors associated with colorectal cancer in Isfahan, Iran.
Methods: In this case-control study, we randomly selected 187 patients with
colorectal cancer who had positive results by colonoscopy and pathology (case group)
and 250 persons who had negative colonoscopy results (control group) from the
Colonoscopy Unit of Al Zahra Hospital and Colorectal Cancer Center of Seyed Al
Shohada Hospital from 2014 to mid-2015. This study aimed to find the risk factors for
sporadic colorectal cancer; therefore, we excluded patients with positive family history.
Participants completed a self-administered questionnaire that asked about sex, age, body
mass index, smoking status, job-related physical activity, and nonsteroidal antiinflammatory
drug consumption.
Results: This study enrolled 187 colorectal cancer patients (98 males and 89
females) and 250 individuals without colorectal cancer (107 males and 143 females).
Multiple analysis demonstrated a significant association of age (odds ratio: 1.04; 95%
confidence interval: 1.02, 1.06) and body mass index (odds ratio: 1.09; 95% confidence
interval: 1.03, 1.15) with colorectal cancer risk. Men had an almost two-fold risk
compared with women (odds ratio: 1.85; 95% confidence interval: 1.14, 2.99). Subjects
who did not use nonsteroidal anti-inflammatory drugs had an almost three-fold risk
compared with nonsteroidal anti-inflammatory drug consumers (odds ratio: 0.34; 95%
confidence interval: 0.19, 0.62). Analysis for job-related physical activity, also indicated
an association between the no/low active group with colorectal cancer (odds ratio no
activity: 36.09; 95% confidence interval: 10.94, 119 and odds ratio low activity: 2.96;
95% confidence interval: 1.43, 6.13).
Conclusion: Knowledge of the risk factors involved in colorectal cancer incidence
makes it possible to identify people at risk and begin risk reduction strategies as well
as screening programs
