Dr. Expert no comments

In a report prepared for presentation Dec. 3 at the 100th annual meeting of the Radiological Society of North America in Chicago (abstract #SSM24-02), the researchers described the results of a clinical trial of the imaging system AlluraClarity, made by Philips Healthcare, on 50 patients with liver cancer. …

Tumor-analysis technology enables speedier treatment decisions for bowel cancer patients

Dr. Expert no comments

A novel medical-imaging technology, TexRAD, which analyses the texture of tumors, has been shown in trials to enable early diagnosis of those bowel-cancer patients not responding to the standard cancer therapy better than other available tumor markers. Furthermore, the TexRAD markers showed the ability to assess at an early stage the likelihood of survival, distinguishing patients who will have a good prognosis from those having poor prognosis. Dr Balaji Ganeshan, one of the Sussex academics whose research led to the development of the technology, said: “By using TexRAD to scan for subtle anomalies in a tumor’s texture, researchers have been able to spot more quickly when treatments are — or are not — working and adjust treatment accordingly. “And because TexRAD simply provides an additional layer of software analysis of the MRI and CT scans that already exist as part of routine clinical practice, it is non-invasive from the patient’s point of view and potentially cost-effective to the healthcare provider.” The technology is being evaluated in a number of research institutions and university hospitals around the world. …

Study questions accuracy of lung cancer screens with FDG-PET technology in some geographic regions

Dr. Expert no comments

Histoplasmosis and other fungal diseases are linked to fungi that are often concentrated in bird droppings and are found in soils. The study by investigators at Vanderbilt University and the Tennessee Valley Healthcare System-Veterans Affairs was led by Vanderbilt first author Stephen Deppen, Ph.D., and principal investigator Eric Grogan, M.D., MPH, and appeared in the Sept. 24 issue of JAMA. …

Positron emission tomography (PET) combined with fludeoxyglucose F18 (FDG) is currently recommended for the noninvasive diagnosis of lung nodules suspicious for lung cancer…

Focus on treatment costs, value: Less radiation for elderly women with early breast cancer — ScienceDaily

Dr. Expert no comments

The study, using a national database of more than 100,000 women treated during the last decade, found that today nationally radiation oncologists are less likely to use radiotherapy in women older than 70 with early-stage estrogen-receptor-positive breast cancer and that when they do, treatment is appropriately less-intensive. This follows a randomized trial demonstrating low rates of recurrence in women who don’t receive radiotherapy after lumpectomy, provided they take endocrine therapy. This confirms radiation oncologists are responding to a growing impetus to keep medical practices current and cost-effective, said first author Charles Rutter, M.D., a radiation oncology resident in Yale’s School of Medicine. …

Knowledge is power: Men who are uneducated about their prostate cancer have difficulty making good treatment choices — ScienceDaily

Dr. Expert no comments

UCLA researchers found that men who aren’t well educated about their disease have a much more difficult time making treatment decisions, called decisional conflict, a challenge that could negatively impact the quality of their care and their long-term outcomes. …

Are you as old as what you eat? Researchers learn how to rejuvenate aging immune cells

Dr. Expert no comments

The two new studies, supported by the Biotechnology and Biological Sciences Research Council (BBSRC), could help to enhance our immunity to disease through dietary intervention and help make existing immune system therapies more effective. As we age our immune systems decline. Older people suffer from increased incidence and severity of both infections and cancer…
