Targeted cancer drugs such as gleevec (Novartis) and Iressa (AstraZeneca), which are portrayed as "magic bullets" because they are designed to hit single, biological targets, have been disappointing. gleevec ended up influencing other genes. Bryan Roth, a biochemist at Case Western Reserve University in Cleveland, says "magic shotguns" rather than "magic bullets" are what's needed.

It is a more promising anti-breast cancer agent than the currently used gene-targeted drugs like gleevec or Er-bitux. [Current Drug Targets 7: 423-42, 2006] See the section in this book on resveratrol. Ginseng and breast cancer Researchers in China were surprised to find, in a recently conducted survey of over 1,000 women diagnosed with breast cancer, that ginseng may have some beneficial properties for women. Compared with patients who never used ginseng, regular users had a significantly reduced risk of death (~29% relative risk reduction) and had better psychological and social well-being.

Avastin, Erbitux, gleevec... The new wonder drugs might make you think we're finally beating this dreaded scourge. We're not. - Clifton Leaf Fortune Magazine, March 9, 2004 Yet, the gene targeted drugs go on being extolled. "Stunning," "revolutionary," "jaw-dropping," "wonder drug," "cuts disease recurrence in half," are the words used to describe the three reports published in the New England Journal of Medicine involving Herceptin (trastuzumab).

Gleevec ended up influencing other genes. Bryan Roth, a biochemist at Case Western Reserve University in Cleveland, says "magic shotguns" rather than "magic bullets" are what's needed. Simon Frantz, writing the lead article in an issue of Nature Magazine, says: "Forget drugs carefully designed to hit one particular molecule - a better way of treating complex diseases such as cancer may be to aim for several targets at once.

Most recently, with media reports celebrating such revolutionary cancer medicines as gleevec, Herceptin, Iressa, Er-bitux, and the just-approved Avastin, the cure has seemed closer than ever. But it's not. Hope and optimism, so essential to this fight, have masked some very real systemic problems that have made this complex, elusive, relentless foe even harder to defeat. The result is that while there have been substantial achievements since the crusade began with the National Cancer Act in 1971, we are far from winning the war. So far away, in fact, that it looks like losing. Living longer?

A drug called gleevec (formeraly known as STI 571) is a protein-tyrosine kinase inhibitor that specifically interferes with the Bcr-Abl tyrosine kinase—the typical chromosomal abnormality seen in chronic myeloid leukemia (CML). gleevec inhibits proliferation and induces apoptosis in Bcr-Abl cell lines as well as fresh leukemic cells from "Philadelphia chromosome positive" chronic myeloid leukemia (CML). gleevec may also inhibit growth of other types of cancer cells.

Nor was the report on the front pages of the New York Times that chose instead to extol gleevec, a disappointing anti-cancer drug that costs $2,500 for a month of treatment. Instead, the media ignored this report which said that a 5-cent pill, heralded by independent researchers, appears to be the biggest cancer breakthrough in history. The report, published in the February 2006 issue of the American Journal of Public Health, did not reveal anything new, but rather tabulated results from scientific reports conducted over the past 40 years that public health authorities had ignored.

It is interesting to note that a drug that functions along a similar mechanism as certain dietary supple-ments was put on the FDA's "fast-track" for approval. CONCLUSION Leukemia, Hodgkin's lymphoma, and non-Hodgkin's lymphoma generally respond well to conventional therapies. There are many different types of these diseases; therefore, chemotherapy and radiation therapy are individualized.

IMATINIB (i MAT in ib) Brand Name: gleevec About Imatinib In chronic myeloid leukemia (CML), the bone marrow produces cancerous white blood cells that, instead of defending the body against invaders, eventually fill up much of the available space in the bone marrow and crowd out other developing blood cells. In dme, these cancerous white blood cells spill over into the bloodstream. In the early stages, CML may produce fatigue, weakness, weight loss, or other symptoms—or may not trigger any symptoms at all. But as the disease advances, a blast crisis will inevitably develop.

Novartis does, however, use the gleevec story to promote itself— implying that all of its drugs are that good.) Important new drugs require very little marketing. Me-too drugs, by contrast, require relentless flogging, because companies need to persuade doctors and the public that there is some reason to prescribe one instead of another. So it is no surprise that the drugs most heavily promoted are me-too drugs, like Nexium and Lipitor and Paxil. We've accounted for the $19.

Thus, most of Novartis's R&D investment in gleevec was made several years after there was good scientific evidence to suggest that the drug would be useful. These kinds of stories could be multiplied many times over. A recent study published in the journal Health Affairs reported that, in 1998, only about 15 percent of the scientific articles cited in patent applications for clinical medicine came from industry research, while 54 percent came from academic centers, 13 percent from government, and the rest from various other public and nonprofit institutions.

Let's look at the pricing of Taxol and gleevec. When it came on the market, Taxol sold for $10,000 to $20,000 for a year's treatment—reportedly a twentyfold markup over manufacturing costs. Bristol-Myers Squibb, you will remember, put next to nothing into the initial R&D, although it has since sponsored clinical trials aimed at expanding the uses of the drug.

He also acknowledged that the price was based partly on the price of interferon, the drug that gleevec replaced as the recommended treatment for chronic myeloid leukemia. In other words, the price was what the market would bear. In response to the outcry over the staggering price to treat this lethal disease, Novartis announced a discounting policy for patients of limited means. But according to a 2003 article in The New York Times, the plan had not worked very well so far, particularly in poor countries, where only a handful of patients have received the drug free.

Witness the initial reluctance of Novartis to undertake development of gleevec.) Nor are people with transient conditions, like most acute infections. Antibiotics, for example, seldom generate huge revenues (there are exceptions here), because while infections are common, they usually do not last very long. Lethal diseases kill the customer, so drugs to treat them are not usually blockbusters, either. Second, the market has to consist of paying customers. It doesn't help the bottom line to turn out drugs for nonpaying customers.

No one would want to be without, say, insulin for diabetes, antimicrobial agents to fight infections, vaccines to prevent a host of serious diseases, anti-clotting agents to treat heart attacks, chemotherapy for cancer, a panoply of effective painkillers and anesthetics, and many others. gleevec is a major advance, as are Epogen and Taxol. Prilosec is important, too, as are statins and ACE inhibitors and many other drugs. All of these agents have extended and greatly improved our lives.

Vesanoid, gleevec and cerivastatin are prescription drugs and should be prescribed by your oncologist or hematologist. Liver Cirrhosis In the human, the liver is the second largest organ in the body (skin being the largest). The liver is about the size of a football and it weighs approxi-mately 4 lbs.

For chronic myeloid leukemia (CML), ask your doctor about gleevec. 7. Water-soluble vitamin A may provide a useful alternative to Vesanoid for some cancer patients. The recommended dosage of this vitamin is 100,000-300,000 IU daily. CAUTION Monthly blood tests are necessary to avoid vitamin A toxicity. 8. Vitamin D3 and its analogs may induce differentiation of cancer cells into normal cells in certain types of lymphomas and leukemias. A high dose to consider is 4000-6000 IU daily.

The herbs complement chemotherapy quite well and give the pet a better chance for long-term survival while minimizing side effects. gleevec, a new human cancer drug, may be helpful to pets in the future. Unfortunately, it is extremely expensive at this time (about $18.00 a capsule). Mammary Cancers To prevent mammary cancers, female dogs must be spayed before the first heat period. Neutering male dogs will prevent testicular tumors, perianal adenomas, as well as prostate disease. It is much better to prevent cancer than to treat it.
