What are the different types of bladder cancer?
- > 90% of bladder cancer is transitional cell carcinoma, 1-7% squamous cell carcinoma (75% SCC where schistosomiasis is endemic), 2. Adenocarcinoma(2%)(2)
What are the clinical features of bladder 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 bladder cancer?
- Suprapubic pain
- Lower urinary tract symptoms
- Metastatic disease symptoms –bone pain, lower limb swelling
What are the investigations of painless visible haematuria in bladder cancer?
- Flexible cystoscopy
- CT urogram
- Renal function
What are the investigations of perisistent microscopic haematuria in bladder cancer?
-Flexible cystoscopy
-US KUB
If biopsy proven muscle invasive then staging investigations
What is Ta staging in bladder cancer?
non invasive papillary carcinoma
What is Tis staging in bladder cancer?
carcinoma in situ
What is T1 staging in bladder cancer?
invades subepithelial connective tissue
What is T2 staging in bladder cancer?
invades muscularis propria
What is T3 staging in bladder cancer?
invades perivesical fat
What is T4 staging in bladder cancer?
prostate, uterus, vagina, bowel, pelvic or abdominal wall
What is N1 staging in bladder cancer?
1 LN below common iliac birufication
What is N2 staging in bladder cancer?
> 1 LN below common iliac birufication
What is N3 staging in bladder cancer?
Mets in a common iliac LN
What is M1 staging in bladder cancer?
distant mets
What is the WHO classification of for bladder cancer?
G1 = well differentiated G2 = moderate differentiated G3 = poorly differentiated
What is a transurtheral resection of bladder lesion?
- uses heat to cut out all visible bladder tumour
1. provides histology and also can be curative
2. . if the tumour extends beyond muscle then the resection is incomplete due to the risk of perforating the bladder
What is non muscle invasive for management protocol for bladder cancer?
If low grade and no CIS then consideration of cystoscopic surveillance +/- intravesicular chemotherapy/BCG
What is muscle invasive for management protocol for bladder cancer?
- Cystectomy
- Radiotherapy
- +/- chemotherapy
- Palliative treatment
How common is prostate cancer?
- 48,500 new prostate cancer cases in the UK every year (4)
- Prostate cancer is the most common cancer in men within the UK(4)
- Incidence rising but mortality rates declining (4)
What are the different types of prostate cancer?
> 95% of prostate cancer is adenocarcinoma
What are the risk factors for prostate cancer?
- Increasing age
- Western nations(Scandinavian countries)
- Ethnicity(African Americans)
What are the clinical features for prostate cancer?
Usually asymptomatic unless metastatic
What are the blood tests in prostate cancer investigations?
- PSA is prostate-specific but no prostate-cancer specific
- Can be elevated in (UTI, prostatitis)
How is MRI used in prostate cancer investigations?
- imaging prior to biopsy testing
- random biopsies of the prostate were associated with an under detection of high grade (clinically significant) prostate cancer and over detection of low grade(clinically insignificant) prostate cancer
- use of risk assessment with multiparametric MRI before biopsy and MRI targeted biopsy is superior to the previous gold standard of transrectal ultrasonography-guided prostate biopsies
How is trans perineal prostate biopsy used for prostate cancer investigations?
- Systematic template biopsies of the prostate
- Widely used in most centres over transrectal biopsies as less risk of infection and able to sample all areas of the prostate.
What is T1 staging in prostate cancer?
non palpable or visible on imaging
What is T2 staging in prostate cancer?
palpable tumour
What is T3 staging in prostate cancer?
beyond prostatic capsule into periprostatic fat
What is T4 staging in prostate cancer?
tumour fixed onto adjacent structure/pelvic side wall
What is N1 staging in prostate cancer?
regional LN (pelvis)
What is M1a staging in prostate cancer?
non regional LN
What is M1b staging in prostate cancer?
bone
What is M1x staging in prostate cancer?
other sites
What is Gleason score in prostate cancer?
Since multifocal two scores based on level of differentiation
2-6 = Well differentiated
7 = Moderately differentiated
8 – Poorly differentiated
What is the management of prostate cancer if young and fit with high grade cancer?
Radical prostatectomy/Radiotherapy
What is the management of prostate cancer if young and fit with low grade cancer?
Active surveillance ( Regular PSA, MRI and Bx)
What is the management of prostate cancer?
- Highly dependent on patient age/comorbidities and stage and grade of prostate cancer
- Post prostatectomy – monitor PSA ( should be undetectable or <0.01ng/ml). If >0.2ng/ml then relapse
What is the management of prostate cancer if old and unfit with high grade cancer/Metastic disease?
Hormone therapy (lower testosterone)
What is the management of prostate cancer if old and unfit with low grade cancer?
Watchful waiting (regular PSA testing)
What are the treatment side effects for prostate cancer?
- Prostatectomy removes the proximal urethral sphincter and changes urethral length.
- Risk of damage to cavernous nerves ( innervation to bladder and urethra)(7)
- Damage to cavernous nerves causes ED
What does the prostate contain?
proximal sphincter
What is a red flag symptom of prostate cancer?
- Painless visible haematuria
- all patients should undergo cystoscopy and imaging
What is PSA?
PSA is prostate specific but not prostate cancer specific
What is the aetiology of bladder cancer?
- Smoking
- Radiotherapy
- Chronic inflammation
- trinchstomitis
- Smoking, occupational exposure( aromatic hydrocarbons), chronic inflammation of bladder (bladder stones, schistosomiasis, long term catheter), drugs (cyclophosphamide), Radiotherapy
