Samira Negrichi, Salima Taleb


Aim: The aim of this study was to determine the epidemiological profile of cancer in Tebessa (East
of Algeria) and to determine the incidence of colorectal cancer according to sex, age and BMI, in a
period extending from 2014 to 2016.
Materials & methods: Data of 604 cancer patients has been collected from Tebessa cancer
registry: Age, sex, address, weight, height, and cancer location. We calculated the frequency of each
type of cancer, the distribution according to sex, age, body mass index, and distribution according
to the communes of the wilaya.  The data was analyzed using Minitab version 13. The statistical
technique used for the analysis is Chi-square test and Student Test.
Results: The most common cancers were: breast cancer, colorectal cancer, lung cancer, cancers of
the respiratory and upper digestive tracts and stomach cancer. Colorectal cancer was ranked the
second after breast cancer with a prevalence of (9.27%). For women, it comes in second place after
breast cancer with a frequency of (6.9%) and in the third place after lung cancer and cancers of the
respiratory and upper digestive tracts among men, with a prevalence of (13.4%). The mean age of
cancer patients (all types of cancer combined) is 53.27 ± 14.10 years old. For colorectal cancer the
mean age of patients was 55.62 ± 14.95 years. The prevalence of cancer increases with age. Colon
cancer was more prevalent in women, while rectal cancer was more common in men. Overweight
and obesity appears to be related to cancer.
This study reinforced data from the literature on the nature and spread of colorectal cancer, and
revealed the existence of different types of cancer in Tebessa.
