Bladder cancer 2 Flashcards
Structures removed with radical cystectomy
men = remove bladder + prostate, followed by urinary diversion
women = typically remove bladder + uterus, followed by urinary diversion
accuracy of staging cystoscopy and TURBT for muscle invasive
Not very accurate, so patients are often upstaged after radical cystectomy
Contraindications to trimodality therapy for bladder preservation
- extensive or multifocal CIS
-tumor-related hydronephrosis - good pre-treatment bladder function
- bunch of others….
What is Stage II anatomically?
The cancer has grown into the inner (T2a) or outer (T2b) muscle layer of the bladder wall, but it has not passed completely through the muscle to reach the layer of fatty tissue that surrounds the bladder.
Stage IIIA or IIIB implies
nodal involvement
what is MVAC?
methotrexate, vinblastine, adriamycin, cisplatin
clinical behavior of the variant histologies (squamous, adeno, micropapillary, nested, plasmacytoid, sarcomatoid)
- more aggressive
T2 disease means
muscle invasive
Management of muscle invasive bladder cancer (T2 disease) generally speaking
- neoadjuvant chemo then cystectomy
Management of patient with T1a disease who has TURBT and visually resected with path showing high grade NMIBC and negative margins
- Repeat TURBT (need to ensure patient does not have component of muscle invasive disease)
Indications for BCG
Intermediate or high risk, non-muscle invasive bladder cancer:
1) cTa, high grade, intermediate risk
2) Tis, AUA high risk disease
3) cT1
management of urothelial cancer of the prostate with stroma invasion
- cystoprostatectomy +/- urethrectomy +/- neoadjuvant chemotherapy
what is cystoprostatectomy
procedure in which the bladder and prostate gland are surgically removed,
Preferred perioperative regimens for MIBC + # of cycles
MVAC with GCSF x 3-4 cycles
Gem-cis x 4 cycles
T4a means
tumor outside bladder invading into surrounding structures (prostatic stroma, uterus, vagina, seminal vesicle)
T4b means
invading pelvic wall or abdominal wall
Evidence for carboplatin-based therapy in MIBC?
- carbo has not demonstrated a survival benefit and should not be substituted for cisplatin
other RF’s for bladder cancer
- aromatic amines and aromatic hydrocarbins
- aristolochia fangchi (herb)
management of MIBC with small cell, neuroendocrine features
- neoadjuvant cis-etoposide followed by XRT or cystectomy (need to use small cell lung cancer chemo regimen – cis-etoposide)
intravesical chemotherapy options for cTa + preferred option
- gemcitabine (preferred) and mitomycin
management of superficial bladder cancers (T1 or less)
TURBT and intravesical chemo within 24 hours
Management of positive urine cytology with negative cystoscopy
- cytology of the upper tract and ureteroscopy
Stage IIIA disease means in terms of N stage
N1 disease
Stage IIIB disease is in terms of nodal staging
> N1 disease
Management of N1 disease
Neoadjuvant cisplatin based combination chemo followed by cystectomy vs. concurrent chemoRT
Management of stage IIIB disease (multiple nodes involved)
- downstaging systemic chemo or concurrent chemoRT
efficacy of gem-cis vs MVAC
- equivalent OS and PFS benefit
preferred regimens for metastatic bladder cancer
Cis-gem (toxicity profile)
DDMVAC
management of patient who isn’t a cystectomy candidate
Trimodality therapy (TMT)
chemo regimens to be given with radiation in bladder + regimen for CKD patients
Cisplatin-taxol
Cisplatin alone
IF renal dysfunction, 5-Fu/mitomycin (MMC)
what are the high risk factors for non-invasive urothelial cancers warranting treatment
- T1
- CIS or Tis
- high grade greater than 3 cm
- high grade multifocal
