Factors associated with clinical benefit from epidermal growth factor receptor inhibitors in recurrent and metastatic squamous cell carcinoma of the head and neck. Cohen EE, Halpern AB, Kasza K, Kocherginsky M, Williams R, Vokes EE. Oral Oncol. 2009 Oct;45(10):e155-60. Epub 2009 Jul 7. PMID: 19586795

Israeli 'cancer shift' over heart disease mortality may be led by greater risk in women with high intake of n-6 fatty acids. Shapira N. Eur J Cancer Prev. 2007 Oct;16(5):486-94. PMID: 17923822 doi: 10.1097/CEJ.0b013e3280145b6d Population studies of Israeli Jews, Arabs, and women support the association of high n-6 polyunsaturated fatty acid intake with increased cancer risk and higher female sensitivity. Research findings suggest that gender and sex hormones may influence n-6 polyunsaturated fatty acid metabolism and carcinogenesis. This appears to be the first time gender has been proposed to modulate national cancer epidemiology, suggesting implications for differential nutritional prevention, warranting further research.

Modulation of prostate cancer genetic risk by omega-3 and omega-6 fatty acids. Berquin IM, Min Y, Wu R, Wu J, Perry D, Cline JM, Thomas MJ, Thornburg T, Kulik G, Smith A, Edwards IJ, D'Agostino R, Zhang H, Wu H, Kang JX, Chen YQ. J Clin Invest. 2007 Jul;117(7):1866-75. PMID: 17607361 Our data suggest that modulation of prostate cancer development by polyunsaturated fatty acids is mediated in part through Bad-dependent apoptosis. This study highlights the importance of gene-diet interactions in prostate cancer.

"ScienceDaily (Oct. 8, 2009) - Women with breast cancer should be given high doses of vitamin D because a majority of them are likely to have low levels of vitamin D, which could contribute to decreased bone mass and greater risk of fractures, according to scientists at the University of Rochester Medical Center." Scientists funded by the NCI analyzed vitamin D levels in each woman, and the average level was 27 nanograms per milliliter; more than two-thirds of the women had vitamin deficiency. Weekly supplementation with high doses of vitamin D -- 50,000 international units or more -- improved the levels, according to Peppone's study. The U.S. Institute of Medicine suggests that blood levels nearing 32 nanograms per milliliter are adequate.

Meta-analysis of vitamin D, calcium and the prevention of breast cancer. Chen P, Hu P, Xie D, Qin Y, Wang F, Wang H. Breast Cancer Res Treat. 2009 Oct 23. [Epub ahead of print] PMID: 19851861 These results provide strong evidence that vitamin D and calcium have a chemopreventive effect against breast cancer.

MedWire News: Serum levels of 25-hydroxy vitamin D (25(OH)D) play a role in prostate cancer disease progression and are a potential prognostic indicator, Norwegian study findings suggest.

MedWire News: Among patients with newly diagnosed prostate cancer, there is no link between circulating steroid hormone levels and Gleason score, conclude US investigators.

Nutritional intervention with omega-3 Fatty acids in a case of\nmalignant fibrous histiocytoma of the lungs. Pardini RS, Wilson D, Schiff S, Bajo SA, Pierce R. Nutr Cancer. 2005;52(2):121-9. PMID: 16201843

ScienceDaily (June 15, 2009) - Using a highly sensitive new test, scientists in Europe are reporting "convincing evidence" that marijuana smoke damages the genetic material DNA in ways that could increase the risk of cancer.

ROCHESTER, Minn. -- Two Mayo Clinic patients whose prostate cancer had been considered inoperable are now cancer free thanks in part to an experimental drug therapy that was used in combination with standardized hormone treatment and radiation therapy. The men were participating in a clinical trial of an immunotherapeutic agent called MDX-010 or ipilimumab. In these two cases, physicians say the approach initiated the death of a majority of cancer cells and caused the tumors to shrink dramatically, allowing surgery. In both cases, the aggressive tumors had grown well beyond the prostate into the

Below is a list of publications covering the research being done by UW and other institutions on artemisinin and cancer. The list is organized into two categories: publications related to the effects of artemisinin and its analogs on cancer and artemisinin pharmacology and pharmacokinetics. You may find them useful when consulting with your personal physician. We have also compiled a comprehensive list of artemisinin-related articles (more than 350 publications) that you may also find useful.

Antitumor activity of human papillomavirus type 16 E7-specific T cells against virally infected squamous cell carcinoma of the head and neck.

Artemisia Annua (Sweet Wormwood) is a shrubby perennial native to China. The leaf of the plant contains up to 0.04 percent Artemisinin. This herb has been used over the centuries by Chinese medical practitioners. Artemisinin came to the attention of the World Health Organization in the 1970s when Quinine lost efficacy against malaria. Artemisinin is the only drug effective against malaria and hundreds of millions of doses are prescribed for that purpose every year. The artemisinin molecule has an affinity for iron, which the malarial parasite sequesters internally. Artemisinin enters the malarial parasite and combines with sequestered iron to create Reactive Oxygen Species, rupturing the parasite. Like malarial parasites, cancer cells concentrate and sequester high levels of iron. Moreover cancer cells overexpress cell surface receptors for iron-containing compounds like ferritin and holotransferrin. Therefore, Artemisinin has a high affinity for cancer cells, and upon entering the cell combines with intercellular iron creating ROS-mediated apoptosis. Artemisinin is the only chemotherapeutic agent that lacks the tertiary amine necessary to usher the drug back out of the cell. This document is based on the research of Dr. Henry Lai and Dr. Narenda Singh at the University of Washington,and the medical practice of Dr. Ba Hoang of Vietnam and San Jose, California. There are a few points of divergence among experts studying Artemisinin, therefore more than one protocol is outlined below.

What is VITAL? The VITamin D and OmegA-3 TriaL (VITAL) is a research study in 20,000 U.S. men and women investigating whether taking daily dietary supplements of vitamin D (about 2000 IU) or fish oil (about 1 gram of omega-3 fatty acids) reduces the risk of developing cancer, heart disease, and stroke in people who do not have a prior history of these illnesses. Recruitment for the study will begin in January 2010.

Evidence from clinical trials shows, with a wide margin of confidence, that a prolonged intake of 10,000IU/d of vitamin D3 poses no risk of adverse effects for adults, even if this is added to a rather high physiologic background level of vitamin D.
