The analysis of 8-year data (2002-2010) of the tumor cases based on the pathology records of Abant Izzet Baysal University medical faculty department.

AIM: Cancer is one of the most significant health problems throughout the world. An important aspect of measures against cancer is to determinate the extension and prevalence of the cancer. Understanding characteristics and behavior of cancer is the key issue in providing preventive steps and developing proper strategies in the concept of early diagnosis and treatment. The objective of this study was to determine the regional cancer incidence and cancer types based on the pathology records of Department of Pathology, Medical School, Abant Izzet Baysal University. Secondly. The aim was to discuss the properties of these cases with other similar reports both from Turkey and the world. MATERIALS AND METHODS: All pathology records of the cases were evaluated who diagnosed at The Department of Pathology, Medical School, Abant Izzet Baysal University between December 20, 2002 and December 31, 2010. The results were classified according to year, age, sex and organ systems. Statistical analyses were carried out using Open Office version 3.1 and PSPP 0.7.2. The duplication of data was particularly prevented by excluding the multiple records in the case of more than one biopsies of the same cancer in the same patient. RESULTS: Totally 18654 pathology records were analyzed. The ratio of positive cases was 24.18% (4510/18654) of including all benign and malignant tumors. Among them 1984 (43.99%) were male and 2526 (56.01%) were female. On the other hand, malignant tumors constituted 33.35 % (1504/18654) of all cases and the percentage of male and female patients were 67.81 % (1020/1504) and 32.19 % (484/1504) respectively. The occurrence of malignant tumors was mostly seen between 60 and 69 age group, while the predominant age period was between 50 and 59 when considering both benign and malignant patients. Male patients had cancers mostly after 60 age group and the predominant period was between 60 and 69 ages. Considering the female patients only, they had more cancers between 10 and 60 age group than males, and the most prevalent period was between 40 and 49 years. The prevalence of both benign and malignant tumors with respect to their origin were skin( 30.15%), female genital tract (21.57%) and gastrointestinal system (12.92%). Considering only the malignant tumors, the distribution was as skin (21.07%), male genital tract (17.82%) and gastrointestinal tract (14.96%). On the other hand, the order of cancers was skin (31.29%), gastrointestinal tract (17.69%), male genital tract (14.81%) in male patients, while it was as female genital tract (38.50%), skin (29.30%), gastrointestinal tract (9.20%) for the female patients. CONCLUSION: Due to our datas, our results are similar to the results in Turkey and the World. The reason of the lower incidence of some tumors such as lung tumors which are much higher in Turkey and the world may depend on technical inadequacy due to our faculty's being a newly established one.
