Currently on a 3 month tour of duty of 5FU (pill)+Avastin. Has anybody seen any advantages of taking VD3 ? Ive read numerous online articles and our ONC seems wishy-washy on the idea. Just wondering whay experiences folks have had here. Looking at possibly 5,000 IU a day for my wife, thx ! Sdino
I just finished 6 months of chemo, and when I ask my oncologist from MD Anderson, he said that D3 is the only supplement he feels is important. He told me to take 1000-2000 IU per day.
In addition, the following links provides information on Vitamin D3 and colon cancer:

If you decide to supplement with Vitamin D3. I think that you would probably have to do periodic blood monitoring to insure that you are not overdosing yourself.
Here is an article from Mayo Clinic that discusses this topic.

The potential problems mentioned for preventive management were mainly calcium toxicity, and deficiencies of magnesium or vitamin K2. We monitor blood calcium on every draw, a little conservative on caution.
In the first month, before surgery and chemo, along with a number of immune modulating supplements and cimetidine, she had an intense immune reaction to her peritoneal dissemination - a localized complete response there, fully necrosed at surgery. Since she was obviously vitamin D deficient in retrospect, I mentally give the vitamin D3, up to 17,000 iu per day, partial credit. To do it again, I'd use more.
During her first year, we sometimes maintained calcium at the high normal level, ca 10+ mg/dL, for a while, then we used a more depositional formulation with lower blood levels of calcium. One of her lung thingies petrified and turned to stone. Perhaps cancer cells can't pump out calcium as well during chemo+IV C+ everything else.
In the second year after vitamin D ramped up to ~40,000 iu per day, a strange breakup and dissolution of liver lesions (not biopsied) occurred. Perhaps including the immune attack effects mentioned by Dr JJ Prendergast. Our radiologist commented a lot about this.
Her osteoporosis got better and her teeth stayed good despite all the years of chemo. This last year, after taking less supplements, she's had more dental work...

Ever since I take 2,000 to 5,000 per day. I will skip the supplement if I actually get a lot of sun that day. But most of us don't get enough sun and can't possibly get enough sun in the winter.
Guys I am not a scientific study, but I am Cured and here 9 years later. With my annual blood test they check my Vit D level.
