Q

How is CIS of penis treated ?

A

Local Excision for well defined tumors

sometimes, CIS may be patchy and poorly defined, surgery may be mutilating and difficult reconstruction, RT is advised

Q

how is primary tumor treated (penile cancer)

A
  1. small tumors confined to glans/spongiosum: penis preserving strategy: glanectomy, EBRT ,BRachy or laser excisioin
  2. Cavernosal involvement: Partial penectomy with at least 5 mm margin,10mm for G3 tumors

3.For T3/t4: total penectomy with periurethral urethrostomy

Q

How is EBRT planned for penile cancer?

A
  1. Circumcision first
  2. wax immobilisation block should be made
  3. Hold penis in vertical position

Q

what should be done for pathological nodes following staging for penile cancer

A

Inguinal Node dissection

for low risk groin: eg only one LN involved withut ECE: no further Rx required

for high risk groin eg.2 LN with ECE: increased risk of local groin rec and pelvic nodal spread 50%, post OP RT is added (groins and Pelvic nodes)

Volume extends from medial border of iliopsoas muscle laterally, medially the medial border of pectineus, and anterly to the skin, should be extended across midline, lymphatics cross midline
