Renal Carcinoma Flashcards
EPIDEMIOLOGY
How does rank in most common types of kidney tumour
The most common type, is adenocarcinoma arising from renal tubules
CLINICAL FEATURES
Classic triad of presentation
- Haematuria
- Flank pain
- Palpable mass
Types of renal cell carcinoma
- Several subtypes of renal cell adenocarcinoma
- Clear cell (80%)
- Papillary (15%)
- Chromophobe (5%)
- Wilm’s tumour specific type affecting kidney in children <5 years
AETIOLOGY
Risk factors
- Smoking
- Obesity
- Hypertension
- End-stage renal failure
- Von Hippel-Lindau disease
- Tuberous sclerosis
CLINICAL FEATURES
Presentation
- May be asymptomatic
- Haematuria
- Vague loin pain
- Palpable renal mass
- Non-specific cancer symptoms
- Weight loss, fatigue, anorexia, night sweats)
Where does it typically spread
- Tissues around kidney within Gerota’s fascia
- Often to renal vein and then inferior vena cava
- “Cannonball metastases” in lungs
What paraneoplastic syndromes commonly associated with
- Polycythaemia
- Due to secretion unregulated erythropoitin
- Hypercalcaemia
- Secretion of hormone that mimics action of parathyroid hormone
- Hypertension
- Increases renin secretion, polycythaemia and physical compression
- Stauffers syndrome
- Abnormal LFT without liver metastasis)
INVESTIGATIONS
First choice
- CT thorax, abdomen, pelvis - definitive for diagnosis and staging
- MRI if contrast is contraindicated
- Bloods
- FBC, calcium, LFT, creatinine
MANAGEMENT
General principles
- MDT team
- Surgery to remove tumour (first line)
- Options if patient not suitable for surgery
- Chemotherapy and radiotherapy may be used
MANAGEMENT
Surgical options
- Partial nephrectomy
- Radical nephrectomy
MANAGEMENT
Non-surgical options
- Arterial embolism
- Percutaneous cryotherapy
- Radiofrequency ablation
What is arterial embolisation
Cutting of blood supply to affected kidney
What is percutaneous cryotherapy
Injecting liquid nitrogen to freeze and kill tumour cell
What is radiofrequency ablation
Needing in the tumouur and using electrical current to kill tumour cells
Staging
- TNM staging is most common
- Also number staging system specific to renal cell carcinoma
