Herceptin and chemotherapy improves response rates without major adverse effects in HER2 breast cancer

Women with a particularly aggressive form of breast cancer seem to do better if they are treated with a combined anthracycline and taxane chemotherapy regimen before surgery, together with trastuzumab (Herceptin) before and after surgery, according to results from the largest multi-centre trial to investigate this treatment.

New type of drug shrinks primary breast cancer tumours significantly in just six weeks

A drug that targets the cell surface receptors that play an important role in many types of cancer can bring about significant tumour regression in breast cancer after only six weeks of use, a scientist told the 6th European Breast Cancer Conference (EBCC-6) (Thursday 17 April).

Treatment with sunitinib slows tumor growth and spread of liver cancer

Treatment with sunitinib slows tumor growth and reduces the risk of metastasis in patients with hepatocellular carcinoma, an aggressive cancer of the liver, researchers report.

Compound found in soybeans may halt spread of prostate cancer

A compound found in soybeans almost completely prevented the spread of human prostate cancer in mice, according to a study published in the March 15 issue of Cancer Research, a journal of the American Association for Cancer Research.

Study explains fundamental process of tumor growth

Nearly 80 years ago, scientist Otto Warburg observed that cancer cells perform energy metabolism in a way that is different from normal adult cells.

ImClone Systems enrols first patient in clinical trial of IMC-1121B to treat liver cancer

ImClone Systems Incorporated has announced that it has enrolled the first patient in a disease-directed Phase II clinical trial of IMC-1121B to treat patients with advanced hepatocellular carcinoma (liver cancer).

Gene therapy - immune system discovery may lead to effective treatment for glioblastoma multiforme

A new gene therapy approach that attracts and "trains" immune system cells to destroy deadly brain cancer cells also provides long-term immunity, produces no significant adverse effects and -- in the process of destroying the tumor -- promotes the return of normal brain function and behavioral skills, according to a study conducted by researchers at Cedars-Sinai Medical Center's Board of Governors Gene Therapeutics Research Institute.

Sunitinib may be associated with cardiac toxicity

Another FDA-approved targeted cancer drug, sunitinib (SutentTM, Pfizer), may be associated with cardiac toxicity, report researchers at Children's Hospital Boston, Dana-Farber Cancer Institute (Boston), and Thomas Jefferson University (Philadelphia).

Profound immune system discovery opens door to halting destruction of lupus

A researcher funded by the Lupus Research Institute (LRI) has discovered an entirely new and powerful molecular switch that controls the inflammatory response of the immune system.

Molecular 'trip switch' shuts down inflammatory response

Like a circuit breaker that prevents electrical wiring from overheating and bringing down the house, a tiny family of three molecules stops the immune system from mounting an out-of-control, destructive inflammatory response against invading pathogens, researchers at the Salk Institute for Biological Studies have found.

Bosutinib safe, effective for chronic myelogenous leukemia

A new drug for chronic myelogenous leukemia works for patients who have developed resistance to frontline therapy and causes fewer side effects than other medications in its class, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports at the 49th annual meeting of the American Society of Hematology.

Data confirm Dasatinib's effectiveness in resistant chronic myelogenous leukemia

Updated clinical trial results show that the drug dasatinib (Sprycel) continues to be highly effective in patients with chronic myelogenous leukemia who were unable to tolerate Gleevec or who developed resistance to it, reports a team led by researchers at Dana-Farber Cancer Institute.

New test for targeted therapy in acute myeloid leukemia

Oregon Health & Science University Cancer Institute researcher Jeff Tyner, Ph.D., has created a way to identify proteins that are candidates for targeted therapy in acute myeloid leukemia using an assay that yields results in just four days.

Pathogens use previously undescribed mechanism to sabotage host immune system

New research identifies a previously unknown enzymatic mechanism that subverts the early host immune response and promotes pathogenicity by manipulating a common signaling pathway in host cells.

Re-engineered Gleevec reduces heart risks

Using a new bottom-up approach for rational drug design, researchers at Rice University and the University of Texas M. D. Anderson Cancer Center have reengineered the powerful anticancer drug imatinib - best known by its brand name Gleevec - to more specifically target one type of cancer while potentially curbing a rare life-threatening cardiotoxic side effect.

Modified form of imatinib becomes more specific

Imatinib (marketed as Gleevec in the US and Glivec in Europe and Australia) is used to treat various cancers, including chronic myeloid leukemia (CML) and gastrointestinal stromal tumors (GISTs).

Chemical peroxynitrite tolerates pain

The repeated use of opiate drugs such as morphine to relieve chronic pain results in individuals having to take higher and higher doses of the drug to achieve equivalent pain relief (they are said to exhibit antinociceptive tolerance).

Blood markers can help choose best dose for antiangiogenic drugs

Scientists at Sunnybrook have new information that may help to improve the use of anti-cancer drugs designed to block the growth of new blood vessels in tumors, a process called angiogenesis that is critical to tumor growth.

Combination targets offer new hope in fight against cancer

While some targeted therapies - drugs developed to attack specific molecules in the critical chemical pathways occurring within cancer cells - work well by themselves, increasingly researchers are finding that they work better when teamed with other targeted and conventional therapies.
