Abstract

Background and Objectives: Kidney cancer is the malignant disease, which is commonly found in the urinary tract system. The aim of this study is to review trends and the characteristics of kidney cancer patients in Srinagarind Hospital during 2000-2010 and analyse the survival time of patients with different stages of disease.

Material and Method: All new kidney cancer cases registered in Srinagarind Hospital between January 1st, 2000 and December 31st, 2010 were included in this study. Our data were obtained from the Khon Kaen Cancer Registry. The characteristics of patients and survival time were analysed.

Results: The overall increment rate of kidney cancer was 10% in both genders. Additionally, male had 11% of such incremental number while 7% increase was found in female. The proportion of new kidney cancer cases: total cancer cases was 1: 169.26 (294: 49,763) or 0.59%. The median age of patient presenting with kidney cancer was 48 years in male and 42 years in female. Patients commonly presented with stage IV at the first diagnosis (43.2%). Overall median survival time of kidney cancer patients were 20.28 months (95% confidence interval (CI), 12.24, 44.76; p < 0.05). In addition, overall median survival time of patients with stage I-III did not reach the analytical point whereas patients with stage IV had 9 months of overall survival time.

Conclusion: The trends of kidney cancers are accelerating increasing. Higher frequency of new kidney cancer cases was presented in male compared to female. The overall survival time was still very short because kidney cancer patients usually presented with advanced stages (stage IV). Therefore, if kidney cancer is intensively concerned and the early stages of disease can be detected, patients might have better prognosis resulting in longer survival time.
