Renal cell carcinoma (referred to as kidney cancer) is a high degree of malignancy in the urinary system of cancer, is one of the most common tumor, is originated in the renal parenchymal epithelial system of malignant tumors, also known as renal adenocarcinoma, accounting for 80% to 90% of malignant renal tumors. According to the survey, kidney cancer occupies the second place in China's genitourinary system tumor, is only next to the bladder tumor, accounts for the adult malignant tumor 2% to 3%, the children malignant tumor about 20%. There was a significant difference in the incidence of both men and women. According to statistics, the ratio of male to female was 2: 1. The incidence of renal cell carcinoma increased with age, data show that the high incidence of renal cell carcinoma in the 40 to 55 years old. In addition, the incidence of renal cancer has a significant international differences, Europe and the United States was significantly higher than the Asian countries, Japan and India, the incidence of lower countries. The incidence of the city is higher than that of the rural areas.
According to GLOBOCAN 2012 World Malignant Tumor Epidemiology study data, the global incidence of renal cancer in the first 14 malignant tumors, mortality ranked 16th.
In 2012, 338000 cases of new renal cancer were estimated in the world, with 143000 deaths, accounting for 2.4% and 1.7% respectively of the incidence and death of malignant tumors.
After gender stratification, it can be seen that the age-standardized incidence of kidney cancer is twice that of females (6/105 vs. 3/105), and the age-standardized mortality rate is about twice that of females (2.5 / 105 vs. 1.2 / 105)
Tips: do a regular physical examination, screening by screening means kidney cancer is the key to early diagnosis and treatment. Currently in clinical, almost all of the early patients are accidental imaging findings found. Early renal cell carcinoma, especially T1 stage renal resection after radical resection, 5-year survival rate of 95% or more, 10-year survival rate of up to 90% or more.
