BACKGROUND AND OBJECTIVE: Colorectal cancer is the fourth most common
cancer in Iran with a diverse geographic distribution. The purpose of this
study was to determine the incidence of colorectal cancer and assess the clinical
and epidemiologic characteristics of survivors in the city of Babol, Iran.
METHODS: In this cross-sectional study, all new cases
of colorectal cancer, recorded by the Cancer Registry Center of Babol, were included
for the assessment of the incidence of colorectal cancer during 2007-2012. Clinical
and epidemiologic features of patients were investigated via interview in 2013.
FINDINGS: A total of 237 patients were registered during the specified
period, although only 120 subjects had survived until 2013. Age-standardized
rate was 7.7 per 100,000 people in 2007, which increased to 14.6 in 2012.
Overall, 54% of subjects were urban residents, 46% were illiterate, 30% were smokers,
16% used hookah, and 10% consumed opium. Family history of colorectal cancer
was reported in 27 patients (22.5%). The average age of survivors was
56.74±14.14 years about a third of patients were younger than 50 years at the
time of diagnosis. The mean interval between the presentation of symptoms and
diagnosis was 10±13.3 months, and the most common symptoms of the disease included
altered bowel habits, rectorhalgia, abdominal pain, constipation, and weight
loss, respectively.
CONCLUSION: The obtained results showed the increased
incidence of colorectal cancer in Babol city. Considering the significant number
of young people and the long interval between the onset of symptoms and definitive
diagnosis, it is recommended that training courses on the warning signs and
screening of colorectal cancer be planned. |
