Stage 0 penile cancer is defined by the following TNM classifications:
Tis, N0, M0
Ta, N0, M0
Carcinomain 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 the majority 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.
Many of the medical and scientific terms used in this summary are found in the NCI Dictionary of Genetics Terms. When a linked term is clicked, the definition will appear in a separate window.
Creating evidence-based summaries on cancer genetics is challenging because the rapid evolution of new information often results in evidence that is incomplete or of limited quality. In addition, established methods for evaluating the quality of the evidence are available for some, but not all, aspects of...
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]
Topical application of 5-fluorouracil cream has been reported to be effective in cases of erythroplasia of Queyrat  and Bowen disease.[Level of evidence: 3iiiDiv]
Imiquimod 5% cream is a topical immune response modifier that has been reported to be effective with good cosmetic and functional results.[8,9,10][Level of evidence: 3iiiDiv]
Laser therapy with Nd:YAG or CO2 lasers has also been reported to result in excellent cosmetic results.[Level of evidence: 3iiiDiv]
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]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage 0 penile cancer. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.
General information about clinical trials is also available from the NCI Web site.
