18
Q

What are the recurrence and progression rates for T1 high grade NMIBC?

A

Recurrence: 45%
Progression: 17%

19
Q

What defines low risk NMIBC?

A

Papillary urothelial neoplasm of low malignant potential

20
Q

What defines intermediate risk NMIBC?

A 
Recurrent low grade Ta within 1 year
Solitary LG Ta > 3cm
Multifocal LG Ta
HG Ta < 3cm 
LG T1
21
Q

What defines high risk NMIBC?

A

HG T1
Recurrent HG Ta
HG Ta > 3cm or multifocal

CIS
BCG failure in HG patient
Any variant histology

LVI
HG prostatic urethral involvement

22
Q

How should NMIBC be diagnosed?

A

By thorough cystoscopy.

23
Q

What should be the initial treatment of NMIBC?

A

At initial diagnosis of a patient with bladder cancer, a clinician should perform complete visual resection of the bladder tumor(s), when technically feasible

24
Q

What should be included in addition to cystoscopy for evaluation of hematuria or a suspected bladder tumor?

A

Upper tract imaging.

25
Q

What should be done if a patient has a normal cystoscopy but positive cytology?

A 
Prostatic urethral biopsies
Upper tract imaging
Ureteroscopy
Blue light cystoscopy
Random bladder biopsies
26
Q

What should be done if NMIBC shows variant histology?

A

Repeat TURBT in 4-6 weeks.

27
Q

What is the rate of muscle invasion with variant histology?

28
Q

What is the preferred tx option for NMIBC with variant histology?

A

Due to the high rate of upstaging associated with variant histology, a clinician should consider offering initial radical cystectomy

29
Q

What are the 5 FDA approved tumor markers?

A 
NMP22
BTA
Urovysion FISH
Immunocyt
Cxbladder
30
Q

What is the role of urinary biomarkers in NMIBC?

A

In surveillance of NMIBC, a clinician should not use urinary biomarkers in place of cystoscopic evaluation.

31
Q

What is the role of urinary biomarkers during surveillance for low risk NMIBC?

A

In a patient with a history of low-risk cancer and a normal cystoscopy, a clinician should not routinely use a urinary biomarker or cytology during surveillance.

32
Q

What is the indication for urinary biomarkers in NMIBC?

A

In a patient with NMIBC, a clinician may use biomarkers to assess response to intravesical BCG (UroVysion® FISH) and adjudicate equivocal cytology (UroVysion® FISH and ImmunoCyt™). (Expert Opinion)

33
Q

What should be done for a patient with NMIBC who underwent an incomplete initial resection?

A

Repeat TURBT if feasible.

34
Q

What is the next step for high risk, high grade, Ta tumors after resection?

A

Repeat TURBT in 6 weeks.

35
Q

What percentage of T1 tumors get upstaged?

36
Q

What is the next step after resection of a T1 NMIBC?

A

Repeat TURBT in 6 weeks.

37
Q

What percentage of high grade Ta NMIBC get upstaged?

38
Q

What percentage of high grade Ta NMIBC have residual tumor?
