Epidemiology and clinical investigation of all cancer types in Kermanshah, Iran (2010–2019)

Background: Epidemiological studies of cancer worldwide can help identify the prevalence of common cancers in the region and may help to organize their control. The study's purpose was to investigate the frequency of cancer in the urban and rural areas in the West of Iran in both sexes based on the pathological data from a single clinical center (2010–2019). Subjects and Methods: A cross-sectional study was designed to assess the demographic and clinical information was obtained from the pathology reports. Organs involved in cancer based on the international classification of disease 10th revision were coded. The variables extracted were sex, age, time of diagnosis, cancer site, and residency status. Quantitative and qualitative variables were analyzed with an appropriate statically analyzing test using the SPSS software. Results: Of the 7728 registered cancers (2010–2019) with mean age 58 ± 17 years, 3384 (44%) were female, 4341 (56%) were male, 2025 cases (26.2%) were rural, and 5687 cases (73.8%) were urban. Regarding the frequency of cancers and the age of diagnosing cancer, there was a statistically significant association between the two genders (P < 0.05). However, no similar conclusion was reached concerning residence status. Conclusion: The most common cancer in both genders was bladder, colorectal, and breast cancer. The frequency of cancers, despite the differences in the percentage of cancers between the two sexes, did not follow the same pattern as other cities in Iran and the world. Our study confirmed that the prevalence of cancer may follow the pattern of the geographical area.
