Abstract

Purpose: The aim of present study was to determine the changes in the incidence of cancer in Bingöl which is in the Nomenclature of Territorial Units for Statistics- 2 (NUTS-2) region, and to perform survival analysis on these patients.

Materials and Methods: This is a retrospective cohort study and the data was obtained from the Ministry of Health's Cancer Registry System. We examined the data of 977 cancer cases diagnosed between year 2013 and 2015 

Results: 28.7% of the patients died during the follow-up period. 30% of all cancers originated from the digestive system. The cancers of lung, stomach, colon, prostate and skin are the mostly seen in the male patients, the cancers of breast, thyroid and skin are the mostly seen in the female patients. The incidence of cancer is increasing over the years and the cancer incidence rate is higher in men. The mean follow-up period was 388 days in died patients and 1541 days in alive patients. The risk of death is increasing in the patients not undergoing surgery (RR = 2.779, HR = 3.048). In addition, the risk of death is decreasing in the patients not receiving chemotherapy (RR = 0.656, HR = 0.340). The risk of death is increasing in the patients with advanced age and the male patients.

Conclusion: The incidence of cancer is increasing. Further indepth and wider research is needed to shed more light on these findings

Abstract

Amaç:The aim of the
present study was to determine the changes in the incidence of cancer in a city
of Turkey, which is in the Nomenclature of Territorial Units for Statistics- 2
(NUTS-2) region, and to perform survival analysis on these patients.

Gereç ve Yöntem:The present study is
a retrospective cohort study. The data of the patients were obtained from the
Ministry of Health's Cancer Registry System. The data of 977 cancer cases
diagnosed in 2013-2015 were examined. 

Bulgular:28.7% of the patients
died during the follow-up period. 30% of all cancers originated from the
digestive system. While the cancers of lung, stomach, colon, prostate and skin
are the mostly seen in the male patients, the cancers of breast, thyroid and
skin are the mostly seen in the female patients. The incidence of cancer is
increasing over the years and the cancer incidence rate is higher in men. The
mean follow-up period was 388 days in died patients and 1541 days in alive
patients. The risk of death is increasing in the patients not undergoing
surgery (RR = 2.779, HR = 3.048). In addition, the risk of death is decreasing
in the patients not receiving chemotherapy (RR = 0.656, HR = 0.340). The risk
of death is increasing in the patients with advanced age and the male patients.

Sonuç:The incidence of
cancer is increasing. It is recommended to conduct longer-term and more
broad-based studies evaluating the treatment efficacy and the effects of
treatment types on survival.
