So, be careful about taking vitamin D IF your doctor is unwilling to reduce the amount of chemo to be given.
Chemo dosages were established for the majority of people who have low levels of vitamin D in their blood.
It appears that if you take the normal Chemo dose AND a good level of vitamin D in your blood you will get 2X the impact.
The impact varies with the type of Chemo, suggest that you search PubMed for "name of chemo" "Vitamin D"

Update 2017 by Founder of VitaminDWiki
A friend of mine got Lung Cancer
I told him it was great to take extra vitamin D, PROVIDED the Chemo dose was monitored and reduced as needed.
Unfortunately the doctors did not adjust the dose until the finally noticed he had so few white blood cells that they could not be mseasured.

Study Shows Benefits of Adding High-Dose Calcitriol to Chemotherapy for Advanced Prostate Cancer: Presented at ASCO - 2002
Calcitriol May Safely Double Effectiveness of Taxotere Treatment
ORLANDO, FL — May 21, 2002 — The addition of high-dose calcitriol to weekly treatment with the chemotherapy agent docetaxel (Taxotere®) appears to improve the therapeutic response in men with hormone-refractory prostate cancer without compromising safety, according to results reported at the 38th Annual Meeting of the American Society of Clinical Oncology (ASCO). Calcitriol is the active form of vitamin D.
Data from a phase II clinical trial suggest as much as twice the efficacy with the docetaxel/calcitriol combination than docetaxel alone, as measured by prostate-specific antigen (PSA) response rate. The study showed that 81 percent of patients treated with the combination regimen cut their PSA levels by more than half. Studies of docetaxel without calcitriol have reported a 42 percent PSA response rate overall. PSA is a substance produced within the prostate gland, and a high PSA level may indicate the presence of cancer. In patients with advanced prostate cancer, PSA correlates with the amount of cancer in the body.

As a steroid hormone that regulates mineral homeostasis and bone metabolism, 1?, 25-dihydroxycholecalciferol (calcitriol) also has broad spectrum anti-tumor activities as supported by numerous epidemiological and experimental studies.
Calcitriol potentiates the anti-tumor activities of multiple chemotherapeutics agents including DNA-damaging agents cisplatin, carboplatin and doxorubicin; antimetabolites 5-fluorouracil, cytarabine, hydroxyurea, cytarabine and gemcitabine; and microtubule-disturbing agents paclitaxel and docetaxel.
Calcitriol elicits anti-tumor effects mainly through the induction of cancer cell apoptosis, cell cycle arrest, differentiation, angiogenesis and the inhibition of cell invasiveness by a number of mechanisms.
Calcitriol enhances the cytotoxic effects of gamma irradiation and certain antioxidants and naturally derived compounds.
Inhibition of calcitriol metabolism by 24-hydroxylase promotes growth inhibition effect of calcitriol.
Calcitriol has been used in a number of clinical trials and it is important to note that sufficient dose and exposure to calcitriol is critical to achieve anti-tumor effect.
Several trials have demonstrated that safe and feasible to administer high doses of calcitriol through intermittent regimen.
Further well designed clinical trials should be conducted to better understand the role of calcitriol in cancer therapy. PMID: 20842231

There are anecdotal data that lower levels of vitamin D may be associated with increased levels of toxicity in individuals receiving chemotherapy; we therefore wished to investigate this further.
From a cohort of over 11 000 individuals, we included those who had vitamin D levels (serum 1,25(OH)(2)D3) measured before and during chemotherapy. They were analysed for side effects correlating Chemotherapy Toxicity Criteria with vitamin D levels, normalising data for general markers of patient health including C-reactive protein and albumin.
RESULTS: A total of 241 (2% of the total cohort) individuals entered the toxicity analysis.
We found no overall difference in toxicity effects experienced by patients depending on whether they were vitamin D depleted or had sufficient levels (P=0.78).
CONCLUSION: This pilot study suggests routine vitamin D measurement during treatment does not appear to be necessary in the management of chemotherapy-induced toxicity.

Antioxidant supplements such as co enzyme Q10, selenium and the vitamins A, C and E can help to prevent cell damage
- VitaminDWiki comment - so Chemo doctors recommend NOT taking them!!

Treatment can last for anywhere from 3 to 6 months. During that time, you would be considered to be immunocompromised — not as able to fight infection. After finishing chemotherapy treatment, it can take anywhere from about 21 to 28 days for your immune system to recover.
- VitaminDWiki Comment: Even if you wait until chemo is done Vitamin D can probably help the immune system recover

Oct 2, 2008 - The odds of having severe vitamin D deficiency (25-OH vitamin D≤15 ng/ml) in a patient receiving chemotherapy was fourfold higher than a patient with colorectal cancer who never received chemotherapy or completed chemotherapy at least 3 months prior to their vitamin D assay.

- 2017 - In the patients who received chemotherapy (45% ), those with sufficient vitamin D levels had a statistically longer survival than those with deficient levels (p<0.002). Also the patients with sufficient levels, they were more likely to complete the 6 months of chemotherapy than those with deficient levels (p<0.006)

- In a laboratory study, vitamin D3 was found to increase breast cancer cell death caused by radiotherapy from approximately 30% to 75%.
- A 2016 study of 1,666 women in California found that higher levels of vitamin D at diagnosis were associated with improved survival, especially among premenopausal women.
- A prospective study which used stored blood of breast cancer patients to measure Vitamin D levels found that women with deficient vitamin D levels had a significantly increased risk of distant recurrence and death compared with those with sufficient levels. The authors concluded that vitamin D deficiency may be associated with poor outcomes in breast cancer.

Cheno is a huge source of revenue to bigpharma Wikipedia
- VitaminDWiki comment -A patient needing less Chemo (due to Vitamin D) results in:
- less income for the hospital: which is a function of cost of chemo and reduced days in hospital
- Doctors/hospitals also get a large income from use of Chem drugs - they buy wholesale but bill retail
Thus often getting an additional income of $2,000/patient/month
We can anticipate lots of resistance to reducing chemo dose sizes as a result of having a good level of Vitamin D
Chemotherapy/Radiation Therapy often upsets digestion Wikipedia
There are several forms of vitamin D for people with poor digestion
- Gut-Friendly Vitamin D
- Vitamin D injection is far better than oral for diabetics (poor gut) – RCT March 2017
- People with poor guts getting nutrition via IV had poor oral Vitamin D bio-availability – May 2017

- Prostate Cancer treatment (Vitamin D, Omega-3, Tumeric) RCT ending Dec 2018 - probably no results published until 2020
Stock up on Vitamin D before surgery or at least before Chemo (provided doctor adjusts the chemo/radiation doses)
For many people 400,000 IU of vitamin D will be sufficient to get a good level (Some will need 2X or 3X more)
Days IU/day 40 days 10,000 IU 8 days 50,000 IU 2 days 200,000 IU
Possible beneifts of having a good level of vitamin D before chemo starts
assuming that chemo dose is reduced
Less hair lost
Less recurrence of cancer
Less spread of cancer
Less bruising, infection
Less weight gain
Less peripheral neuropathy
Less hearing loss
Less reduction in fertility
Fewer bone problems
Fewer heart problems
Fewer mouth sores
Note: Currently no chemo drug is known to be amplified by vitamin D by more than 2X
But, if chemo dose for the drug is reduced by only 2X the resulting chemo drug + Vitamin D could potentially be deadly
Wonder if there is any data on Vitamin D levels when taking many chemo drugs
