Overview
Wilms tumours are the most common paediatic renal mass. There is no recognised gender predilection. It typically occurs in early childhood (1-11 years) with peak incidence between 3 and 4 years of age.
Epidemiology and Demographics
Prevalence
Wilms tumours are the most common paediatic renal mass, accounting for over 85% of cases and accounts for 6% of all childhood cancers.[1]
Incidence
The incidence of Wilms tumor is 7.1 cases per 1 million children younger than 15 years. Approximately 500 cases of Wilms tumor are diagnosed in the United States each year.[2]
Age
It typically occurs in early childhood (1-11 years) with peak incidence between 3 and 4 years of age. Approximately 80% of these tumours are found before the age of 5 years. When part of a syndrome they occur even earlier, typically between 2 and 24 months of age.[1] The mean age at diagnosis is 44 months in unilateral cases of Wilms tumor and 31 months in bilateral cases. [2]
Sex
The male to female ratio in unilateral cases of Wilms tumor is 0.92:1.00, but in bilateral cases it is 0.60:1.00. [2]
Race
The incidence is substantially lower in Asians. [2]
