Renal cell carcinoma produces IL-6, which can increase platelet counts. Some combination of these mechanisms may turn out to be the link between high platelet count and higher rates of death. The IL-6 could be increasing the platelet count. The organization also said renal cell carcinoma accounts for about 85 percent of all kidney tumors and represents 2 percent of all adult cancers. Renal cell carcinoma primarily occurs in adults between 50 and 70 years old, and men are twice as likely as women to be diagnosed.
Radical nephrectomy is the standard treatment.
