Q

T stage -4

A

superficial (Tis, Ta, T1) (70-80% of pts)
carcinoma in-situ (if untreated 60-70% will progress), ->NEED TO TX
papillary

muscle invasive (T2-T4) (20-30% of pts) (high-grade)

Q

superficial (Tis, Ta, or T1) primary tx -5

WHAT IS TOC?

A

SURGERY + ADJUVANT

TURBT (transurethral endoscopic resection)

adjuvant intravesicular BCG x 6wks
—10 yr PFS 62 vs 37%

can do observation and just one dose of BCG without surgery for Ta dz (NOT COMMON)

BCG better than doxo

Q

BCG ADR - important to manage sx to give entire course (3pts)

A

flu: (phenazopyridine, APAP, NSAIDs)

#cystitis and infx: 
urine and b cx to r/o infx. 
usually higher and prolonged fever than in flu-like sx

(1-34%) usually self limiting,
HOLD BCG until resolves,
usually 2nd, 3rd, or 4th dose

Q

muscle invasive (T2 to T4a) primary tx -4

WHAT IS TOC?

A

NEOADJ + SURGERY IS TOC

organ confined -> radical cystectomy unless contraindx, THEN CAN GIVE XRT.

can also use combined chemoXRT surgery to preserve bladder in select cases

neoadj x 3 cycles: CMV or M-VAC

adj chemo NO OS ADVANTAGE, some MD’s may give for T3 disease

Q

muscle invasive (T2 to T4a) primary tx -neoadj concepts

A

3 cycles appear beneficial

need combo tx (no benefit from single agent cis)

Q

muscle invasive (T2 to T4a) primary tx -adj concepts

A

NO OS advantage

for T3 or above 3 cycles may be used to delay recurrence (especially if neoadj not given)

Q

stage IV primary tx -5

WHAT IS SOC?

A

M-VAC used historically but toxic

cis-gem is TOC: OS pretty close (13.8 vs 14.8mo), much less tox.

carbo-gem (only other phase III trial) (give if can not have cisplatin in M-VAC or cis-gem)

pac-carbo

pac-gem (give if can not use platinum at all)

Q

stage IV M-VAC principle

A

if use instead of cis-gem give in dose dense manner (inc PFS with same tox) NCCN req- LOOK UP
