In which gender is RCC more common
Males
What age does RCC typically onset
55-years
What are 3 causes of RCC
- Sporadic
- Von Hippel Lindau Syndrome
- Tuberous sclerosis
What is the inheritance pattern of von-hippel-lindau
Autosomal dominant
what type of renal cancer does von-hippel-lindau cancer cause
Clear cell renal cell carcinoma
what two neurological disorders does von-hippel-lindau cause
Cerebellar hemangiomas -SAH
Retinal hemangiomas - Vitreous haemorrhage
what is the inheritance pattern of tuberous sclerosis
Autosomal dominant
what are cutaneous features of tuberous sclerosis

what is problem with RCC
Asymptomatic during early-stages
what is the triad of symptoms in RCC
Haematuria
Abdominal mass
Flank pain
when should RCC always be investigated for in males and why
Left varicocele.
Left testicular vein drains into left renal vein - meaning a mass (cancer) obstructive drainage can cause varicocele
what are 4 paraneoplastic syndromes of RCC
- PTHrp
- ACTH
- Renin
- EPO
- Stauffer syndrome
what does EPO cause
Polycythaemia
what does PTHrp cause
Hypercalcaemia
what is stauffer syndrome
Paraneoplastic hepatic dysfunction syndrome
what causes paraneoplastic hepatic dysfunction syndrome
Release of IL6
how does stauffer syndrome present clinically
Hepatosplenomegaly and cholestasis
what are renal cell carcinomas
adenocarcinomas that arise from the proximal convoluted tubule (PCT) of the kidney
what is the most common variant of renal cell carcinoma
clear-cell renal cell carcinoma
when should individuals be referred under 2WW for suspected renal carcinoma
> 45-years with:
- Unexplained macroscopic haematuria
- Haematuria persisting despite treatment for UTI
what is the main symptom that should ring alarm bells for RCC referral
> 45 and haematuria
