Bladder Flashcards
What are some familial syndromes and genes associated with bladder cancer?
- Lynch
- Peutz-Jeghers
- Li-Fraumeni
- Neurofibromatosis
- Cowden
GENES
- N-acetyltransferases (NAT1 and NAT2 genes)
- glutathione S-transferases
What are some malignant markers of bladder cancer?
- most common is loss of chromosome 9 (esp. 9q)
- p16 - > 50% of all bladder CA, squamous.
- p53 - high grade, assoc. with CIS
- RB - aggressive, assoc. with CIS
- PTEN - assoc. with CIS
- p27 - aggressive
- RAS
- Ki-67 - aggressive
- FGFR3 - low grade, low malignant potential Ta
How would you stage a urothelial cancer that is a direct invasion through the bladder and into the prostatic stroma
T4
How would you stage a tumor that it’s in the prostatic urethra
T2 urethral
What is BCG Refractory
Persistent disease in 6 months or progression at 3 months
What is BCG Relapse
Recurrence after treatment (12 months or later)
What are the indications for 2nd look re-resection?
- Incomplete tumor resection
- high grade Ta or T1
- Large (>3cm) or multifocal tumor
What’s the percent of upstaging on re-resection
15% for Ta
30% for T1
What is the percent of persistent disease on re-resection?
48%
What are the rates of recurrence and progression for T1 and CIS?
RECURRENCE: 80% for both
PROGRESSION: 50% for T1, 40-80% for CIS
What is considered low risk bladder cancer?
PUNLUMP,
Low grade Ta < 3cm
What is considered intermediate risk bladder cancer?
Low grade Ta > 3cm Multifocal low grade Ta Recurrent low grade Ta in < 1 year High grade Ta < 3cm Low grade T1
What is considered high risk bladder cancer?
High grade Ta > 3cm Multifocal high grade Ta Recurrent high grade Ta High grade T1 CIS Multivariant LVI high grade prostatic involvement any BCG failure
what is the purpose of peri-operative intravesical chemotherapy?
Reduce the recurrence rate by 35%
Who should get peri-operative intravesical chemotherapy?
Low or intermediate risk
What is the recommended regimen for maintenance BCG?
3 week cycles at month 3, 6, 12, 18, 24, 30, 36
what is the purpose of peri-operative intravesical chemotherapy?
To prevent recurrence and progression of disease
What is BCG unresponsive?
- BCG refractory (persistent)
2. BCG relapse within 6 months (recur)
What is the surveillance schedule for low risk bladder cancer?
No cytology
No imaging
Cysto: 3, 12, then annual
What is the surveillance schedule for intermediate risk bladder cancer?
Imaging Q1-2y
Cytology
Cysto: 3, then 3-6mo x 2y, then 6-12mo x 2y, then annual
What is the surveillance schedule for high risk bladder cancer?
Imaging Q1-2y
Cytology
Cysto: Q3mo x 2 yr, Q6mo x 2 year, then annual
What is the purpose of enhanced cystoscopy
- Increase detection
2. Reduce recurrence
What are the indications for immediate cystectomy?
- Variant histology
- LVI
- Persistent T1 on re-resection (no BCG)
- BCG failure
How do you treat BCG sepsis?
isoniazid, rifampin, ethambutol +/- steroids
what is the most clinical or pathologic parameter associated with progression of NMIBC?
tumor stage
also, grade and presence of CIS
how do you manage a positive urethral margin
CONSIDER delayed total urethrectomy
What is the regimen for neoadjuvant chemotherapy and who gets it?
- MVAC or Gem/Cis
2. muscle invasive bladder CA
Who gets adjuvant chemotherapy?
Extravesical disease (T3 or T4) or positive lymphadenopathy at time of cystectomy
What are the contraindications to an orthotropic neobladder?
- Positive urethral margin
- Chronic renal insufficiency
- Liver failure
- neurologic disease affecting dexterity
- Urethral stricture disease
- gross positive margins
- involvement of pubic bone
- chronic inflammatory bowel disease
- malignant bowel disease
What is the best treatment for those undergoing bladder preservation therapy with residual disease after 2 cycles of chemo?
Cystoprostatectomy
What is first line for metastatic bladder CA?
Gem/Cis or MVAC
If Cisplatin ineligible:
- Gem/Carbo,

What is 2nd line for metastatic bladder CA after progression on cisplatin?
Pembrolizumab (preferred)
Erdafitinib
Immune checkpoint inhibitor
What can you give for metastatic bladder and failed cisplatin and immune checkpoint inhibitor?
Enfortumab
Ertafitinib
