The analysis of 8-years data (2002-2010) of the tumor cases based on the pathology records of aibu, school of medicine

INTRODUCTION: Cancer contemporarily constitutes one of the most significant health problems throughout the world. Consequently, a remarkable amount of investigations are performed in terms of preventing the development of cancer. An important aspect of measures against cancer is to determinate the extension and prevalence of 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: A systemic retrospective review of all pathology records of the cases evaluated and diagnosed at the Department of Pathology, Medical School, Abant Izzet Baysal University between December 20, 2002 and December 31, 2010 was carried out. The results were classified based on year, age, sex and organ systems. Statistical analyses were carried out using Open Office version 3.1. 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: A total of 18654 pathology records was retrospectively analyzed. The ratio of positive cases was 24.18% (4510/18654) 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 years of ages, while the predominant age period was between 50 and 59 years of ages when considering both benign and malignant patients. Male patients had cancers mostly after 60 years of age and the predominant period was between 60 and 69 years of ages. Considering the female patients only, they had more cancers between 10 and 60 years of age than males, and the most prevalent period was between 40 and 49 years of ages.The prevalence of both benign and malignant tumors with respect to their origin were cutaneous sites, female genital tract and gastrointestinal system in 30.15%, 21.57% and 12.92 % of cases, respectively. Considering only the malignant tumors, the distribution was as cutaneous sites, male genital tract and gastrointestinal tract in 21.07%, 17.82% and 14.96% of patients, respectively.On the other hand, the order of cancers was cutaneous sites (31.29%), gastrointestinal tract (17.69%), male genital tract (14.81%), in male patients, while it was as female genital tract (38.50 %), cutaneous sites (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.
