For Tis and Ta
Imiquimod 5% apply at night 3x/week for 4-16 weeks

33
Q

Laser therapy: indications and types

A

For Tis, Ta, and T1 (Grade 1-2)
CO2, Nd:YAG (deepest penetration) and KTP

Use 3%-5% acetic acid – HPV infected skin turns white upon exposure – targetable for laser ablation

Use plume evacuator during laser treatment

PN-A

34
Q

Wide local excision

A

For Tis, Ta, T1

Shaft: with or without circumcision
Distal prepuce: circumcision alone may be reasonable
Re-resection if positive surgical margins

PN-A

35
Q

Glansectomy

A

For distal tumors Ta, Tis, and T1 on the glans/prepuce

Negative surgical margins from frozen sections of the cavernosal bed and urethral stump
Treatment followed by STSG and FTSG to form neoglans

Q

Mohs surgery

A

Alternative to wide local excision
For small proximal superficial lesions to avoid total penectomy

PN-A

37
Q

Partial and total penectomy

A

Standard for high-grade primary penile tumors
Functional penile stump can be preserved and negative margins must be obtained
If partial not possible –> total penectomy

Intraop frozen sections: determine negative margins

PN-B

38
Q
