Growth Factor Antagonists in Prostatic Cancer: Suramin and Cytotoxic Polyamines as Potential Therapy
Prostatic Cancer is the leading site for cancer in men over 50 years of age and is the second leading cause of cancer deaths in the US (1). Clinically manifest prostatic cancer is more common in the US than in Japan while the incidence of latent cancer is similar between the two countries. The incidence of prostatic cancer of first generation males of Japanese living in the US is the same as that of US males. The implication is that life style differences are important for the progression of the disease. As prostatic cancer is refractory to most standard chemotherapeutic agents and hormone therapy is only palliative it may be that it will be easier to prevent the progression of prostatic cancer than to cure it. Consideration should be given to 3 omega unsaturated fatty acids, which are common in fish oils, as possible agents in a study of prevention of progression. The 3 omega unsaturated fatty acids have proven beneficial in the prevention of cancer and reduced the growth of prostatic cancer in nude mice (2,3). Other cultural differences in nutrition such as the use of green tea should be investigated to identify other potential anti-tumor progression factors.
