Management of elderly patients with lung cancer

Management of elderly patients with lung cancer

Half of all patients diagnosed with non-small cell lung cancer are 70 years of age or older, yet despite this high percentage, these elderly patients are not well represented in clinical trials. Therefore, the paucity of clinical data has made it difficult to reach evidence based clinical recommendations. In 2010, the EORTC Cancer in the Elderly Task Force and Lung Cancer Group along with the International Society for Geriatric Oncology (SIOG) wrote an expert opinion on managing treatment for elderly patients with non-small cell lung cancer (NSCLC), and now, in an article appearing in the Annal s of Oncology , they have updated their expert opinion.

Radiation therapy for cervical cancer increases risk for colorectal cancer

Radiation therapy for cervical cancer increases risk for colorectal cancer

Researchers at the University of Texas Medical Branch at Galveston are the first to recommend that young women treated with radiation for cervical cancer should begin colorectal cancer screening earlier than traditionally recommended. The UTMB researchers, finding a high incidence of secondary colorectal cancers among cervical cancer survivors treated with radiation, offer new recommendations that the younger women in this group begin colorectal cancer screening about eight years after their initial cervical cancer diagnosis instead of waiting until age 50 Continue reading

Experimental blood test spots recurrent breast cancers, monitors response to treatment

Experimental blood test spots recurrent breast cancers, monitors response to treatment

Johns Hopkins Kimmel Cancer Center investigators report they have designed a blood test that accurately detects the presence of advanced breast cancer and also holds promise for precisely monitoring response to cancer treatment. Continue reading

Blocking DNA repair mechanisms could improve radiation therapy for deadly brain cancer

Blocking DNA repair mechanisms could improve radiation therapy for deadly brain cancer

UT Southwestern Medical Center researchers have demonstrated in both cancer cell lines and in mice that blocking critical DNA repair mechanisms could improve the effectiveness of radiation therapy for highly fatal brain tumors called glioblastomas. Radiation therapy causes double-strand breaks in DNA that must be repaired for tumors to keep growing Continue reading

Blood test could detect solid cancers

Blood test could detect solid cancers

A blood sample could one day be enough to diagnose many types of solid cancers, or to monitor the amount of cancer in a patient’s body and responses to treatment. Previous versions of the approach, which relies on monitoring levels of tumor DNA circulating in the blood, have required cumbersome and time-consuming steps to customize it to each patient or have not been sufficiently sensitive. Now, researchers at the Stanford University School of Medicine have devised a way to quickly bring the technique to the clinic. Continue reading

Helium ions may provide superior, better-targeted treatment in pediatric radiotherapy, study suggests

Helium ions may provide superior, better-targeted treatment in pediatric radiotherapy, study suggests

For the first time, researchers have been able to demonstrate that the use of helium ions in radiation therapy could provide accurate treatment to tumours while helping to spare healthy organs. A treatment planning study to be presented at the ESTRO 33 congress today Sunday has been able to show that helium may have effects that are superior to radiotherapy using protons, themselves a considerable advance on conventional photon beam radiotherapy Continue reading

New test developed to detect men at high risk of prostate cancer recurrence

New test developed to detect men at high risk of prostate cancer recurrence

A new genetic “signature” to identify prostate cancer patients who are at high risk of their cancer recurring after surgery or radiotherapy has been developed by researchers in Canada, the 33rd conference of the European Society for Radiotherapy and Oncology (ESTRO33) in Vienna will hear today (Saturday).

Antioxidants can protect against omega 6 damage — or promote it

Antioxidants can protect against omega 6 damage — or promote it

Given omega 6 fatty acid’s reputation for promoting cancer — at least in animal studies — researchers are examining the role that antioxidants play in blocking the harmful effects of this culprit, found in many cooking oils. After all, antioxidants are supposed to prevent DNA damage. Continue reading

Self-healing engineered muscle grown in the laboratory

Self-healing engineered muscle grown in the laboratory

Biomedical engineers have grown living skeletal muscle that looks a lot like the real thing. It contracts powerfully and rapidly, integrates into mice quickly, and for the first time, demonstrates the ability to heal itself both inside the laboratory and inside an animal Continue reading
