The anticancer efficacy of the Gonzalez regimen has been investigated in two human studies ( CPMC-IRB-8544 ), both involving patients with pancreatic cancer.
The first study, a prospective nonconsecutive case series conducted by the developer and an associate, included 11 patients diagnosed with adenocarcinoma of the pancreas (stage II through stage IV). None of the patients had received chemotherapy or radiation therapy, and none had undergone surgical resection with curative intent. All the...
For lesions limited to the foreskin, wide local excision with circumcision may be adequate therapy for control.
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:
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.[9,10,11,12]
Current Clinical Trials
Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with stage I 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.
