CT/MRI in staging renal cell carcinoma

Area of Science:

• Oncology
• Epidemiology

Background:

• Renal cell carcinoma (RCC) is the eighth most common malignancy, representing approximately 3% of new cancer diagnoses.
• The incidence of RCC has notably increased by 40% in the USA between 1974 and 1990.
• This rise appears to be a genuine increase, not solely due to enhanced detection via imaging.

Purpose of the Study:

• To summarize the epidemiology and key characteristics of renal cell carcinoma.
• To highlight trends in RCC incidence and survival.
• To identify risk factors and specific populations affected by RCC.

Main Methods:

• Review of epidemiological data on renal cell carcinoma incidence and survival.
• Analysis of demographic factors including age, sex, and race.
• Identification of predisposing conditions and associated risk factors.

Main Results:

• RCC incidence has increased, with improved 5-year survival linked to earlier diagnosis via imaging.
• The male to female ratio is approximately 2:1, with most cases occurring in the fifth to seventh decades of life.
• Predisposing factors include von Hippel-Lindau disease (36% of patients) and long-term dialysis (3-6 times higher risk).

Conclusions:

• The increasing incidence of renal cell carcinoma is a significant public health concern.
• Advances in diagnostic imaging contribute to earlier detection and improved patient survival.
• Specific genetic conditions and long-term dialysis are identified risk factors for RCC.
