Nutrition prior to PC radiation

A close friend has a recent diagnosis of PC. He will start radiation treatment about a month from now. Any ideas where to get information about nutrition considerations prior to radiation treatment and then after this series of treatments ends?

Re: Nutrition prior to PC radiation

His RO may ask him to stay on some kind of low fiber, low gas diet while on radiation. I didn't have to because I had only 5 treatments (I strongly recommend he look into hypofractionated SBRT (e.g., CyberKnife) rather than IMRT -- after 5 years, it has been shown to work better and have fewer side effects).

He should avoid any supplements that are potent antioxidants or free-radical absorbers -- they will counteract what he's trying to achieve with the radiation. That includes Vitamin E, Vitamin C, Selenium and Multi-Vitamins.

The best thing he can do for himself is exercise - plenty of it. The increased oxygenation will help the radiation work better, counter any fatigue, and protect healthy tissue.

What he ideally wants are substances that may increase the radiosensitivity of the cancer cells while being radioprotective of healthy tissue. Supplements that may help accomplish this are soy isoflavones, quercetin and aspirin. By prescription, there is evidence that statins and Celebrex may have synergistic effects with the radiation. There is recent evidence that low dose Viagra, started with the radiation therapy and continues 6 months afterwards, may protect sexual function. He should also have sex as often as he can throughout the treatment and afterwards. Blood flow is protective.
