This complementary and alternative medicine (CAM) information summary provides an overview of the use of Newcastle disease virus (NDV) as a treatment for people with cancer. The summary includes a brief history of NDV research, a review of laboratory and animal studies, the results of clinical trials, and possible side effects of NDV-based therapy. Several different strains of NDV will be discussed in the summary, including the Hungarian strain MTH (More Than Hope)-68. Information presented in some...
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.[2,3,4,5] 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). Some, but not all, observational studies also suggest that male newborncircumcision 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.
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]
