32. Discussion
• Introduction:
• Penile carcinoma is mostly a squamous cell carcinoma (SCC)
but other types of carcinoma exist as well. It usually originates
from the epithelium of the inner prepuce or the glans. Also,
penile SCC occurs in several histological subtypes. Penile SCC
shares similar pathology with SCC of the oropharynx, the
female genitalia (cervix, vagina and vulva) and the anus.
33. •EPIDEMIOLOGY
• The annual age-adjusted incidence is 0.7-3.0 in 100,000 men
in India. 8.3 per 100,000 men in Brazil and even higher in
Uganda.
• Penile cancer is common in regions with a high prevalence of
human papilloma virus (HPV)
• According to race ; The highest incidence of penile cancer
found in white Hispanics (1.01 per 100,000), followed by a
lower incidence in Alaskan, Native American Indians (0.77 per
100,000), blacks (0.62 per 100,000) and white non-Hispanics
(0.51 per 100,000)
• Recently, an increased incidence has been reported from
Denmark and the UK. A longitudinal study from the UK has
confirmed a 21% increase in incidence over the period 1979-
2009 . The incidence of penile cancer increases with age, with
an age peak during the sixth decade of life. However, the
disease does occur in younger men.
34. RISK FACTORS
• Phimosis OR 11-16 versus no phimosis (2,3)
• chronic penile inflammation (balanoposthitis related to
phimosis)
• balanitis xerotica obliterans (lichen sclerosus)
• sporalene and UV-A phototherapy for various dermatologic
conditions such as psoriasis
• smoking 5-fold increased risk versus non smokers
• HPV infection condylomata acuminata
• Rural areas, low socio-economic status, unmarried
• multiple sexual partners early age of first intercourse

extension of any regional lymph node metastasis
• pM - Distant Metastasis
• pM0 No distant metastasis
• pM1 Distant metastasis
• G - Histopathological Grading

• G1 Well differentiated
• G2 Moderately differentiated
• G3-4 Poorly differentiated/undifferentiated
38. Stage
• 0 - Tis or Ta, N0, M0
• 1 - T1a, N0, M0
• 2 - T1b or T2 or T3, N0, M0
• 3 - T1-3, N1, M0 or T1-3, N2, M0
• 4 - T4, any N, M0 or any T, N3, M0 or any T, any N, M1
39. Investigations
• Primary tumour
• Physical examination, recording morphology, extent and invasion of penile
structures.
• MRI with artificial erection in selected cases with intended organ preserving
surgery.
• Inguinal lymph nodes
• Physical examination of both groins, recording number, laterality and
characteristics of inguinal nodes
• • If nodes are not palpable, invasive lymph node staging in high-risk patients.
• • If nodes are palpable, a pelvic CT may be indicated, PET/CT is an option.
• Distant metastases
• In N+ patients, abdomino-pelvic CT scan and chest X-ray are required for
systemic staging. PET/CT scan is an option.
• In patients with systemic disease or with relevant symptoms, a bone scan may
be indicated.
41. T3 with invasion of the urethra
• Partial penectomy or total penectomy with perineal urethrostomy.
T4 with invasion of other adjacent structures
• Neoadjuvant chemotherapy followed by surgery in responders.
Alternative: palliative external beam radiation.
Local recurrence after conservative treatment
• Salvage surgery with penis-sparing treatment in small recurrences or
partial amputation.
• Large or high stage recurrence: partial or total amputation.
Metastatic spread
• Treatment options include systemic chemotherapy or radiotherapy
or radiotherapy with concurrent chemotherapy [58]
• a) Responders receive consolidation ILND
• b) For those with no response/ disease progression, consider salvage
systemic chemotherapy or radiotherapy for local control and/or best
supportive care/ clinical trial
43. Chemotherapy
Neoadjuvant
• Neoadjuvant, cisplatin-based chemotherapy should be considered
the standard (prior to ILND) in patients with ≥4 cm inguinal lymph
nodes (fixed or mobile), if FNA is positive for metastatic penile
cancer. Patients with initially unresectable (T4) primary tumors may
be downstaged by response to chemotherapy.
• A Tx, N2-3, M0 penile cancer can receive 4 courses of neoadjuvant
paclitaxel, ifosfamide, and cisplatin (TIP). Stable or responding
disease should then undergo consolidative surgery with curative
intent.
The phase II response rate was 50% in the neoadjuvant setting.
The estimated rate of long-term progression-free survival for intent
to treat was 36.7%.
Improved progression-free and overall survival times were associated
with objective response to chemotherapy.
44. Adjuvant
• There are no sufficient data to form conclusions about the
use of adjuvant chemotherapy. By extrapolation from the
neoadjuvant data, it is reasonable to give 4 courses of TIP in
the adjuvant setting if it was not given preoperatively and the
pathology shows high-risk features.
Adjuvant EBRT or chemoradiotherapy can also be considered
for patients with high-risk features, which include any of the
following:
• Pelvic lymph node metastases
• Extranodal extension
• Bilateral inguinal lymph nodes involved
• 4 cm tumor in lymph nodes
45. Metastatic/Recurrent
• TIP is a reasonable first-line treatment for patients with metastatic
penile cancer, including palliative treatment of patients with distant
metastases.
• 5-FU + cisplatin has been used historically for metastatic penile cancer
and can be considered as an alternative to TIP. It appears to be effective
for some patients, although the toxicities may be limiting and require
dose reductions.
• Bleomycin-containing regimens are associated with unacceptable
toxicity and are no longer recommended.
• There are no randomized clinical trials due to the rarity of penile
cancer in industrialized countries.
Second-line
• No standard second-line systemic therapy exists.
• A clinical trial is preferred. The evidence to support the palliative use of
second-line therapy is limited.6 In select patients, paclitaxel7or
cetuximab8 may be considered, especially if not previously treated with
a similar class of agent.
46. Preferred combination chemotherapy regimens
• Paclitaxel 175 mg/m2 IV over 3 hours on Day 1
• Ifosfamide 1200 mg/m2 IV over 2 hours on Days 1–3
• Cisplatin 25 mg/m2 IV over 2 hours on Days 1–3
• Repeat every 3 to 4 weeks
• 5-FU + cisplatin4 (category 2B)
• Continuous infusion 5-FU 1000 mg/m2/d IV on Days 1–5
• Cisplatin 100 mg/m2 IV on Day 1
• Repeat every 3 to 4 weeks
Radiosensitizing agents and combinations (Chemoradiotherapy)
• Preferred
• Cisplatin alone, or in combination with 5-FU
• Alternate options
• Mitomycin C in combination with 5-FU
• Capecitabine (for palliation)
47. Radiotherapy
Primary Radiation Therapy (Penile Preservation)
T1-2, N0
If tumor <4 cm
• • Circumcision followed by either:
• Brachytherapy alone (preferred approach) (should be performed with interstitial implant);
or
• EBRT with or without concurrent chemotherapy:Total dose 65–70 Gy with conventional
fractionation using appropriate bolus to primary
• penile lesion with 2-cm margins. Consider prophylactic EBRT to inguinal lymph nodes in
patients who are not surgical candidates or who decline surgical management.
If tumor ≥4 cm
• • Circumcision followed by either:
• EBRT with concurrent chemotherapy:45–50.4 Gy to a portion of or whole penile shaft
depending on bulk and extent of lesion plus pelvic/ inguinal nodes, then boost primary
lesion with 2-cm margins (total dose 60–70 Gy);
or
• Brachytherapy (in select cases and with careful post-treatment surveillance)
48. T3-4 or N+ (surgically unresectable)
Circumcision followed by:
• EBRT with concurrent chemotherapy: 45–50.4 Gy to whole penile
shaft, pelvic lymph nodes, and bilateral inguinal lymph nodes, then
• boost primary lesion with 2-cm margins and gross lymph nodes (total
dose 60–70 Gy).
Postoperative Adjuvant Radiotherapy
• Inguinal Lymph Node Positive
• Inguinal and pelvic lymph node EBRT to 45–50.4 Gy (strongly consider
concurrent chemotherapy).
• Boost gross nodes and areas of extracapsular extension to a total dose
of 60–70 Gy.
• Treat primary site of disease if positive margin.
• Primary Site Margin Positive
• Primary site of disease and surgical scar EBRT to 60–70 Gy (for close
margin consider radiation treatment vs. observation).
• Treat bilateral inguinal lymph nodes and pelvic lymph nodes if no or
inadequate lymph node dissection.
• Brachytherapy
