While this Godandprostate website mainly focuses on the spiritual aspects of prostate cancer, I have interspersed scientific information as I have received it. An example follows from December, 2009. It is highly recommended that you review the periodicals mentioned above for the latest research status and current findings related to prostate cancer detection and treatment.
December 6th, 2009:
Naturally-occurring prostate cancer inhibitors under investigation:
a) Pomegranate: In a Phase II clinical study at UCLA involving 46 men with rising PSA after prostate cancer treatment (surgery or radiation) who consumed 8 ounces of POM Wonderful 100% Pomegranate Juice daily over two years, PSA doubling time (a measure of prostate cancer progression) increased from 15 to 54 months. A longer term (6-year) continued evaluation of an active sub-group of patients showed a further increase in PSA doubling time to 88 months. [Ref. Pantuck, A.J., et al, Clinical Cancer Research, 2006; 12(13), 4018; July 1, 2006.] Personally, I take pomegranate extract pills and drink a concentrated pomegranate juice daily. While there are a number of sources of pomegranate, I found that the POM Wonderful website was useful. Also I strongly suggest an e mail subscription the newsletter entitled Zero, the Project to End Prostate Cancer. Its November 10th, 2009 e mail included an article from NaturalNews.com, 11/9/09, entitled “Protect the Prostate with Pomegranates.” Zero’s Newsletter gives a lot of recent research findings and should be must-reading for anyone with prostate cancer.
b) Fish oil: Omega-3 fatty acids found in many fish such as salmon, mackerel and bluefish, may help prevent aggressive prostate cancer according to a recent article summarized in Johns Hopkins Newsletter (January, 2010). A recent study (published in Clinical Cancer Research, vol. 15, p.2559,) analyzed the diets of 466 men with aggressive prostate cancer and compared them with the eating habits of similar healthy men. They found that men who ate the most dark fish were 57% less likely to develop aggressive prostate cancer than those who never ate fish. The protective benefits of the fish were greatest in men genetically predisposed to the cancer.
c) Flaxseed: Plants such as the Norway spruce produce chemicals called lignans to protect against disease. When humans ingest lignans, bacteria in our colon convert the plant lignans to a different chemical form called enterolactones, which have been shown in laboratories to suppress hormone-dependent cancers such as prostate and breast cancer. These enterolactones produce cell death (apoptosis) in cultured prostate cells. In the clinic, flaxseed-supplemented diets generated favorable reduction in tumor proliferation in men with pre-surgical prostate cancer in as little as 30 days [reference: Demark-Wahnefried, W. et al, Cancer Epidemiol. Biomarkers Prev. 2008, Dec. 17(12), 3577-87.] Personally I also take a flaxseed oil pill and a portion of flaxseed with my morning cereal. The flaxseed is available at most food stores.
There are numerous other naturally-found extracts (e.g. saw palmetto, nettle root, and boswellia) as well as specific drugs [e.g. finasteride (Proscar) and dutasteride (Avodart)] that may be useful in prostate cancer prevention or other prostate conditions such as benign prostatic hyperplasia (BPH). But I will not address them here since my focus is prostate cancer.
d) Curcumin: This is the chemical found in the Indian spice turmeric used to make curry. Curcumin has been shown to possibly play a role in prostate cancer prevention. Curcumin also may interfere with prostate cancer proliferation and metastasis by its action inducing apoptosis (cell death). It is currently being studied in numerous major laboratories and clinics as a non-toxic alternative for prostate cancer prevention, treatment or co-treatment. Personally, I take one curcumin pill daily with food.
e) Pectasol-Modified Citrus Pectin (MCP): This is a modified citrus pectin derived from the rind and peel of citrus fruit. It may inhibit the spread of cancer by binding to galectin molecules and blocking them. Galectins are adhesion and blood vessel-attracting surface molecules that are thought to be involved in the spread of cancer. A small study in 2003 revealed a significant reduction in PSA rise in men where primary conventional treatment was initially successful but in whom serum PSA’s began to climb again. [Ref. Guess, B.W. et al, Prostate Cancer Prostatic Dis., 2003; 6(4); 301-304.]
Therapeutics under development (as of early 2010).
In addition to the FDA-approved drug, taxotere, used for treating prostate cancer which has become resistant to hormonal therapy, there are a number of new treatments under development. Much more information can be obtained by reading the references in the website section on Cancer Information Resources especially from AWARE, the Newsletter of Zero-The Project to End Prostate Cancer, the Prostate Cancer Research Institute (PCRI) and from the National Cancer Institute Bulletin. Some examples of new treatments include the following.
Provenge® (developed by Dendreon) has been approved by the FDA in 2010 for use in men with advanced prostate cancer. The drug has been shown to improve overall survival in men with metastatic androgen-independent prostate cancer. Provenge may be the first in a new class of active cellular immunotherapies which engage the patient’s own immune system to fight cancer.
Johnson & Johnson’s experimental drug abiraterone can help men with advanced prostate cancer who have run out of standard treatments options. The latest Phase III study tested it in patients after treatment with both hormone therapy and taxotere, the only currently approved chemotherapy to show benefit in late-stage prostate cancer. Abiraterone produced strong decreases in PSA levels and shrank or stabilized men’s cancers for an average of almost six months.
A new drug (MDV3100) by Medivation, Inc. offers a radically different way of attacking prostate cancer. It showed promising results in an initial trial and is set for larger-scale testing. A study report in the journal Science looked at this drug’s ability to block the receptors for androgens which drive tumor growth on cells.
Serious potential side effects related to androgen deprivation (hormonal) therapy (ADT). Vitamin D. Many articles have recently been published describing the side effects of ADT or hormonal therapy. In the USA today, perhaps 700,000 prostate cancer survivors are receiving ADT and are therefore vulnerable to loss of libido, hot flashes, anemia, fatigue, accelerated bone loss, increased fat mass, increased cholesterol and triglyceride levels, decreased insulin sensitivity and loss of cognition. These adverse metabolic effects are associated with greater risks for fractures, diabetes and cardiovascular disease. It is emphasized that primary care physicians and patients should be aware of the potential benefits and harms of ADT. Guidelines to prevent fractures, diabetes, and cardiovascular disease in prostate cancer survivors should be incorporated into the management of all patients on long-term ADT. A new drug called denosumab is currently under development by Amgen specifically for the treatment of bone loss in men with non-metastatic prostate cancer undergoing ADT. To avoid fractures, it is also recommended that men undergoing ADT have bone density measurements every two years or so. Bisphosphonates such as Fosamax or newer drugs such as Reclast or Zometa may also be recommended to prevent osteoporosis. Zometa is used for patients with bone metastases. Calcium supplements (two with every meal) are also recommended. It is also thought that vitamin D deficiency plays a role in cancer development. Many scientists and physicians now state that the minimum daily requirement of vitamin D has been grossly underestimated. Recent studies have shown that as many as 85% of subjects tested showed a vitamin D deficiency. It is advised that prostate cancer patients especially those undergoing hormonal therapy be tested for vitamin D levels in their blood (using the assay for 25-hydroxy-vitamin D). Optimal serum levels have not been clearly defined but some researchers state that 36-40 ng.mL (or 90-100 nmol/l) may be ideal. While large doses of vitamin D can be toxic, many researchers including my own physician recommend a minimum of 2000 IU’s of vitamin D daily. [Ref. Espinosa, G., Integrative Medicine and Prostate Cancer, in Prostate Cancer Research Institute (PCRI) Insights, November, 2009, Vol. 12, No. 4, pp.2-7]. This can be found in individual supplements or associated with calcium supplements such as Citrical. Maintaining proper calcium and vitamin D levels, checking one’s bone density and maintaining a disciplined exercise program can help to minimize potential side effects such as bone fractures in ADT. Your own physician should be consulted first to ascertain your personal treatment regimen.
