This complementary and alternative medicine (CAM) information summary provides an overview of the use of PC-SPES as a treatment in people with cancer. The summary includes a brief history of PC-SPES research, the results of clinical trials, and possible adverse effects of PC-SPES. Included in this summary is a discussion of the contamination of PC-SPES and its withdrawal from avenues of distribution.
This summary contains the following key information:
PC-SPES is a patented mixture of eight...
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]
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.
