Epidemiological profile of digestive cancers at Oran EHU, 2012–2017

Introduction There is a particular interest of digestive cancers, due both to their frequency and severity (1.85 million deaths worldwide according to the WHO). Epidemiological studies are necessary means to approach this worrying situation. Digestive tract cancers have varying incidence, progressing mainly because of the increase of colorectal cancer cases, which occupies the third position among most prevalent cancers worldwide. The objective of our work is to describe the epidemiological profile of digestive cancers in the hospital and university establishment of Oran (EHUO) during the period from 2012 to 2017. Methods The data were collected from the EHUO clinical register of cancers. Primary malignant tumors are coded according to CIMO2 and CIM10. Results There are 395 cases of digestive tract tumor in the period 2012–2017. The mean age of the patients is 56.3 ± 2.7 years. The sex ratio is 1.07. The most common histological type is adenocarcinoma (83.6%) Colorectal cancer remains the most frequent localization (59.3%) of digestive cancers followed by gastric cancer with a frequency of 32%. Surgical treatment is initial in 77.6% of cases. Conclusion Cancer registries are the tools of choice for studying the epidemiological characteristics of digestive cancers, establishing prognoses and evaluating the political and health programs, in order to improve their management and reduce their impact.
