A study on distribution of cancer cases diagnosed in Çorum.
OBJECTIVE
In order to help obtain accurate knowledge and to contribute to the establishment of data for regional tumor statistics, we aimed to determine the frequency distribution of cancer cases that was diagnosed in Çorum province.


METHODS
In this descriptive study, we retrospectively reviewed the archive records of the pathology departments' of one university hospital and two private hospitals serving in the province of Çorum. A total of 138,973 recorded pathology reports were reviewed. Metastatic cancers with a known primary source were excluded. A total of 2184 cases with a diagnosis of cancer were recorded by gender, age, and system/organ and classified to 10 most frequent types of cancer both in general and in terms of gender distribution.


RESULTS
The male to female ratio was 1.44 and the mean age was 64.26 years. The cancer is most commonly encountered between 70 and 79 years of age (35.27%) in males whereas the second most common interval was 60 to 69 years of age (23.88%). In females, the cancer is most commonly encountered between 70 and 79 years of age (24.16%) whereas the second most common interval was 60 to 69 years of age (22.60%). The top five cancers were skin (33.60%), prostate (13.87%), stomach (9.07%), urinary bladder (8.61%) and breast (7.88%).


CONCLUSIONS
Distribution of organ/system involvement of cancer cases that were diagnosed in Çorum is quite different from the data regarding Turkey in general. Development of cancer registry centers, upgrading to an active registry system and having all cancer data from health institutions unified in a single organization are mandatory to achieve reliable data.
