General Information About Penile Cancer

Incidence and Mortality

Estimated new cases and deaths from penile (and other male genital) cancer in the United States in 2019:[1]
  • New cases: 2,080.
  • Deaths: 410.

Risk Factors

Penile cancer is rare in most developed nations, including the United States, where the rate is less than 1 per 100,000 men per year. Some studies suggest an association between human papillomavirus (HPV) infection and penile cancer.[2-5] Observational studies have shown a lower prevalence of penile HPV in men who have been circumcised (odds ratio, 0.37; 95% confidence interval, 0.16–0.85).[6] Some, but not all, observational studies also suggest that male newborn circumcision is associated with a decreased risk of penile cancer.[7,8] According to published data, if the relationship is causal, the number needed to treat was about 909 circumcisions to prevent a single case of invasive penile cancer.[9]

Treatment Overview

When diagnosed early (stage 0, stage I, and stage II), penile cancer is highly curable. Curability decreases sharply for stage III and stage IV. Because of the rarity of this cancer in the United States, clinical trials specifically for penile cancer are infrequent. Patients with stage III and stage IV cancer can be candidates for phase I and phase II clinical trials testing new drugs, biologicals, or surgical techniques to improve local control and distant metastases.
The selection of treatment depends on the following:[10,11]
  • Size.
  • Location.
  • Invasiveness.
  • Stage of the tumor.

Cellular Classification of Penile Cancer

Virtually all penile carcinomas are of squamous cell origin and include the following subtypes:
  • Verrucous carcinoma.[1]
  • Warty carcinoma (verruciform).[2]
  • Basaloid carcinoma.[3]
Although they are less common subtypes, warty carcinoma and basaloid carcinoma appear to be more highly associated with human papillomaviruses (HPV), particularly HPV 16, than typical squamous cell carcinoma or verrucous carcinoma of the penis.[3-5]
In addition, neuroendocrine carcinomas can also be seen.[6]

Stage 0 Penile Cancer

Stage 0 penile cancer is defined by the following TNM classifications:[1]
  • Tis, N0, M0
  • Ta, N0, M0
Carcinoma in situ of the penis is referred to as erythroplasia of Queyrat when it occurs on the glans, and Bowen disease when it occurs on the penile shaft. These precursor lesions progress to invasive squamous cell carcinoma in 5% to 15% of cases. In case series studies, human papillomavirus DNA has been detected in most of these lesions.[2,3] With no data from clinical trials in this disease stage, treatment recommendations are largely based on case reports and case series involving limited numbers of patients.
Treatment options:
  1. Surgical excision can result in scarring, deformity, and impaired function. To minimize these effects, Mohs micrographic surgery, which involves the excision of successive horizontal layers of tissue with microscopic examination of each layer in frozen section, has been used in patients with in situ and invasive penile cancers.[4,5][Level of evidence: 3iiiDiv]
  2. Topical application of 5-fluorouracil cream has been reported to be effective in cases of erythroplasia of Queyrat [6] and Bowen disease.[7][Level of evidence: 3iiiDiv]
  3. Imiquimod 5% cream is a topical immune response modifier that has been reported to be effective with good cosmetic and functional results.[8-10][Level of evidence: 3iiiDiv]
  4. Laser therapy with Nd:YAG or CO2 lasers has also been reported to result in excellent cosmetic results.[11][Level of evidence: 3iiiDiv]
  5. Cryosurgery has been reported to result in good cosmetic results in patients with erythroplasia of Queyrat and verrucous penile carcinoma.[12,13][Level of evidence: 3iiiDiv]

Stage I Penile Cancer

Stage I penile cancer is defined by the following TNM classification:[1]
  • T1a, N0, M0
Stage I penile cancer is curable.[2]
Standard treatment options:
  1. For lesions limited to the foreskin, wide local excision with circumcision may be adequate therapy for control.
  2. For infiltrating tumors of the glans with or without involvement of the adjacent skin, the choice of therapy is dictated by tumor size, extent of infiltration, and degree of tumor destruction of normal tissue. Equivalent therapeutic options include:
    • Penile amputation.[3]
    • Radiation therapy (i.e., external-beam radiation therapy and brachytherapy).[4,5]
    • Microscopically controlled surgery.[6]
Treatment options under clinical evaluation:
  • Nd:YAG laser therapy has offered excellent control/cure with preservation of cosmetic appearance and sexual function.[7,8]
Because of the high incidence of microscopic node metastases, elective adjunctive inguinal dissection of clinically uninvolved (negative) lymph nodes in conjunction with amputation is often used for patients with poorly differentiated tumors. Lymphadenectomy can carry substantial morbidity, such as infection, skin necrosis, wound breakdown, chronic edema, and even a low, but finite, mortality rate. The impact of prophylactic lymphadenectomy on survival is not known. For these reasons, opinions vary on its use.[9-12]

Stage II Penile Cancer

Stage II penile cancer is defined by the following TNM classifications:[1]
  • T1b, N0, M0
  • T2, N0, M0
  • T3, N0, M0
Standard treatment options:
  • Stage II penile cancer is most frequently managed by penile amputation for local control. Whether the amputation is partial, total, or radical will depend on the extent and location of the neoplasm. External-beam radiation therapy and brachytherapy with surgical salvage are alternative approaches.[2-6]
Treatment options under clinical evaluation:
  • Nd:YAG laser therapy has been used to preserve the penis in selected patients with small lesions.[7]
Because of the high incidence of microscopic node metastases, elective adjunctive dissection of clinically uninvolved (negative) lymph nodes in conjunction with amputation is often used for patients with poorly differentiated tumors. Lymphadenectomy, can carry substantial morbidity, such as infection, skin necrosis, wound breakdown, chronic edema, and even a low, but finite, mortality rate. The impact of prophylactic lymphadenectomy on survival is not known.[8-11]
To reduce the morbidity associated with prophylactic lymphadenectomy, dynamic sentinel node biopsy is being used in patients with stage T2 clinically node-negative penile cancer. One retrospective single-institution study of 22 patients reported a false-negative rate of 11%.[12]

Stage III Penile Cancer

Stage III penile cancer is defined by the following TNM classifications:[1]
  • T1–3, N1, M0

Inguinal adenopathy in patients with penile cancer is common but may be the result of infection rather than neoplasm. If palpable enlarged lymph nodes exist 3 or more weeks after removal of the infected primary lesion and completion of a course of antibiotic therapy, bilateral inguinal lymph node dissection should be performed.
In cases of proven regional inguinal lymph node metastasis without evidence of distant spread, bilateral ilioinguinal dissection is the treatment of choice.[2-5] Because many patients with positive lymph nodes are not cured, clinical trials may be appropriate.
Standard treatment options:
  1. Clinically evident regional lymph node metastasis without evidence of distant spread is an indication for bilateral ilioinguinal lymph node dissection after penile amputation.[6]
  2. Radiation therapy may be considered as an alternative to lymph node dissection in patients who are not surgical candidates.
  3. Postoperative radiation therapy may decrease incidence of inguinal recurrences.
Treatment options under clinical evaluation:
  • Clinical trials using radiosensitizers or cytotoxic drugs are appropriate. A combination of vincristine, bleomycin, and methotrexate has been effective as both neoadjuvant and adjuvant therapy.[7] Cisplatin (100 mg/m²) as neoadjuvant therapy plus continuous-infusion 5-fluorouracil has also been shown to be effective.[6] Single-agent cisplatin (50 mg/m2) was tested in a large trial and was found to be ineffective.[8]
Because of the high incidence of microscopic node metastases, adjunctive inguinal dissection of clinically uninvolved (negative) lymph nodes in conjunction with amputation is often used for patients with poorly differentiated tumors. Lymphadenectomy can carry substantial morbidity, such as infection, skin necrosis, wound breakdown, chronic edema, and even a low, but finite, mortality rate. The impact of prophylactic lymphadenectomy on survival is not known. [3,4,9,10]
To reduce the morbidity associated with prophylactic lymphadenectomy, dynamic sentinel node biopsy is being used in patients with stage T2 and stage T3 clinically node-negative penile cancer. One retrospective single-institution study of 22 patients reported a false-negative rate of 11%.[11]

Stage IV Penile Cancer

Stage IV penile cancer is defined by the following TNM classifications:[1]
  • T4, Any N, M0
  • Any T, N3, M0
  • Any T, Any N, M1
No standard treatment exists that is curative for patients with stage IV penile cancer. Therapy is directed at palliation, which may be achieved either with surgery or radiation therapy.
Standard treatment options:
  1. Palliative surgery may be considered for control of the local penile lesion and even for the prevention of the necrosis, infection, and hemorrhage that can result from neglected regional adenopathy.
  2. Radiation therapy may be palliative for the primary tumor, regional adenopathy, and bone metastases.
Treatment options under clinical evaluation:
  • Clinical trials combining chemotherapy with palliative methods of local control are appropriate for such patients (tested chemotherapeutic drugs with some efficacy include vincristine, cisplatin, methotrexate, and bleomycin). The combination of vincristine, bleomycin, and methotrexate has been effective both as adjuvant and neoadjuvant therapy.[2]

Recurrent Penile Cancer

Locally recurrent disease can be approached by surgery or radiation therapy. If the initial treatment of radiation therapy fails, patients are often salvaged by penile amputation. Patients with nodal recurrences that are not controllable by local measures are candidates for phase I and phase II clinical trials testing new biologicals and chemotherapeutic agents.[1-5]
