1b Urological Cancers and BPH Flashcards
What are the risk factors for kidney cancer?
Smoking, renal failure and dialysis, obesity, hypertension
Which condition leads to a genetic predisposition to kidney cancer?
Von Hippel-Lindau
What is the most common type of kidney cancer?
Adenocarcinoma - renal cell carcinoma
What is the most common symptom which might suggest Kidney Cancer?
Painless, visible Haematuria
Which investigations should be done if painless, non visible haematuria was present?
Flexible cystoscopy
CT urogram
Renal Function
What investigations should be done is persistent non-visible haematuria was present?
Flexible cystoscopy
US KUB
What investigations should be done if kidney cancer is suspected?
CT renal triple phase
Staging CT chest
Bone scan if symptomatic
What are the main clinical features of Kidney Cancer?
Painless haematuria/persistent microscopic haematuria can is a red flag symptom and can reflect any of these urological malignancies
What are some additional features of renal cell carcinoma?
Loin pain
Palpable mass
Metastatic disease symptoms –bone pain, haemoptysis
Palpable bladder lesions
Penile Mass – rectal exam to assess the size of the cancer
What is the grading system used for kidney cancer?
Fuhrman grade
1 = well differentiated
2 = moderate differentiated
3 + 4 = poorly differentiated
Describe the criteria for the TMN staging of RCC?
T1 – Tumour ≤ 7cm
T2 – Tumour >7cm
T3 – Extends outside kidney but not beyond ipsilateral adrenal or perinephric fascia
T4 – Tumour beyond perinephric fascia into surrounding structures
N1 – Met in single regional LN
N2 – met in ≥2 regional LN
M1- distant met
What is the gold standard for kidney cancer management?
Gold standard is excision either via:
Partial nephrectomy (single kidney, bilateral tumour, multifocal RCC in patients with VHL, T1 tumours (up to 7cm)
Radical Nephrectomy
What treatment is offered to patients with kidney cancer, but small tumours and unfit for surgery?
Cryosurgery - Freeze
What treatment can be given to patients with metastatic kidney cancer?
Receptor tyrosine Kinase Inhibitors
What are the risk factors for Bladder cancer?
Smoking, occupational exposure( aromatic hydrocarbons), chronic inflammation of bladder (bladder stones, schistosomiasis, long term catheter), drugs (cyclophosphamide), Radiotherapy
What is the most common type of bladder cancer?
Transitional cell carcinoma
Which parasite can cause bladder cancer?
schistosomiasis
What is the main clinical feature of bladder cancer?
Painless haematuria/persistent microscopic haematuria can is a red flag symptom and can reflect any of these urological malignancies
What are the additional features of bladder cancer?
Suprapubic pain
Lower urinary tract symptoms and UTI
Metastatic disease symptoms – bone pain, lower limb swelling
What investigations should be done if the patient has painless visible haematuria?
Flexible cystoscopy
CT urogram
Renal function
What investigations should be done if the patient has persistent visible haematuria?
Flexible cystoscopy
US KUB
At what point would you state staging investigations for bladder cancer?
If the biopsy has proven to invade the muscle - then start staging investigations
What classification system is used for bladder cancer?
WHO classification
G1 = well differentiated
G2 = moderate differentiated
G3 = poorly differentiated
Describe the TMN staging for bladder cancer?
TNM staging of Bladder cancer
Ta – non invasive papillary carcinoma
Tis – carcinoma in situ
T1 – invades subepithelial connective tissue
T2 – invades muscularis propria
T3 – invades perivesical fat
T4 – prostate, uterus, vagina, bowel, pelvic or abdominal wall
N1 – 1 LN below common iliac birufication
N2 - >1 LN below common iliac birufication
N3 – Mets in a common iliac LN
M1- distant mets
What technique is used to remove bladder tumours?
A transurethral resection of bladder lesion uses heat to cut out all visible bladder tumour.
