Recommended treatment for bone metastases not widely used

“Palliative radiotherapy, comprising l or more fractions (i.e., treatments) of daily radiation, is the mainstay of treatment for painful bone metastases. In 2005, a U.S.-based randomized trial demonstrated no difference in pain relief between single- and multiple-fraction radiotherapy for uncomplicated bone metastases, confirming results from international trials,” according to background information in the article appearing in the October 9 issue of JAMA…

When more medicine isn’t always better: High costs of unnecessary radiation for terminal cancer patients

"Increased use of single fraction treatment would achieve the Holy Grail of health reform, which is real improvements in patient care at substantial cost savings," said the new study’s lead author, Justin E. Bekelman, MD, an assistant professor of Radiation Oncology in Penn Medicine’s Abramson Cancer Center…

Multivitamins with minerals may protect older women with invasive breast cancer

"Our study offers tentative but intriguing evidence that multivitamin/mineral supplements may help older women who develop invasive breast cancer survive their disease," said Sylvia Wassertheil-Smoller, Ph.D., lead author of the study and distinguished university professor emerita of epidemiology and population health at Albert Einstein College of Medicine of Yeshiva University. Multivitamin/mineral supplements are the most commonly consumed dietary supplements among U.S. adults. They usually contain 20-30 vitamins and minerals, often at levels of 100 percent of U.S…

Does good cholesterol increase breast cancer risk?

Now, a team of researchers led by Philippe Frank, Ph.D., a cancer biologist in the Department of Biochemistry and Molecular Biology at Thomas Jefferson University, has shown that an HDL receptor found on breast cancer cells may be responsible for this effect, proposing a new molecular target that could help treat the disease. …

Battling defiant leukemia cells

Chronic myeloid leukemia (CML) is an aggressive cancer of the blood that is often treated with a drug called Imatinib (a.k.a. Gleevec). Although Gleevec is highly effective, some cancer cells can develop resistance to the drug. The mechanism that drives this resistance is not completely understood, but there is evidence that cancerous stem-like cells are particularly resistant and help to perpetuate disease. …

Rising trend in genome mapping delivers targeted breast cancer treatment

Even more promising, clinical research trials at a few select institutions around the country, including Cleveland’s University Hospitals Case Medical Center Seidman Cancer Center, are part of a development in a rising trend toward targeted treatments as a result of genomic profiling of tumors. …

Minimally invasive operation helps elderly patients after colon cancer treatment

Investigators from Dalhousie University, Halifax, Nova Scotia, found that selected patients over the age of 70 were more likely to be discharged to their own homes — instead of a nursing facility — following laparoscopic operations when compared with patients who had a standard open surgical procedure, according to Richard Liu, MD, a resident in general surgery. "There is evidence that laparoscopic surgical treatment for colon cancer is similar to an open operation in terms of outcomes from a cancer treatment point of view," Dr. Liu said…

New therapeutic target that prevents cell division

The Cell Division & Cancer Group, led by Spanish National Cancer Research Centre (CNIO) researcher Marcos Malumbres, has managed to decode a new mechanism that regulates cell division, in which the key molecule involved, Greatwall − also known as Mastl− could be a new therapeutic target for oncology treatments. The study is published today in the scientific journal Proceedings of the National Academy of Sciences (PNAS). GREATWALL: A KEY PLAYER OF THE CELL DIVISION PUZZLE The control of cell division or mitosis depends on many proteins, amongst them, Aurora and Polo. Currently, many pharmaceutical companies have shown interest in these molecules, for which inhibitors have already been developed, some of which are currently undergoing clinical trials in oncology…

Biomarker, potential targeted therapy for pancreatic cancer discovered

These findings, being published in the Oct. 4, 2013, online edition of PLOS ONE, also show that the use of a biotherapy consisting of a lysosomal protein, known as saposin C (SapC), and a phospholipid, known as dioleoylphosphatidylserine (DOPS), can be combined into tiny cavities, or nanovesicles, to target and kill pancreatic cancer cells…
