U. S. citizenship linked to whether foreign-born non-citizens receive mammograms, cancer tests

According to the research, foreign-born female non-citizens living in the U.S. for less than five years have 69 percent lower odds of being screened for colorectal cancer within the previous five years and foreign-born non-citizens who have lived in the U.S. for at least five years have 24 percent lower odds, compared to U.S born citizens. Additionally, foreign-born non-citizens have significantly lower odds of receiving breast and cervical cancer screening…

Quality of care improves for cancer patients who get palliative care consultation

Palliative care is the medical specialty that focuses on improving quality of life for patients and their families in the setting of a serious illness. Palliative care teams provide an added layer of support to patients, caregivers, and doctors by addressing unremitting symptoms, helping with decision making, and coordinating care. The American Society of Clinical Oncology (ASCO) selected a total of four high-impact abstracts, including this one, to feature in an official press briefing for its upcoming 2013 Quality Care Symposium. More than 270 abstracts will be presented at the conference, which will be held in San Diego on November 1-2…

Investigational PARP inhibitor promising in BRCA-related cancers

When there is damage to DNA in human cells, two proteins, PARP 1 and 2, recruit proteins that can repair the damage associated with loss of BRCA proteins. Mutations in BRCA genes often result in inefficient repair of damaged DNA, which increases the risk for developing certain cancers, including cancers of the breast and ovary. Inhibiting PARP, therefore, prevents the repair of damaged DNA, leading to cell death. …

Blood-pressure drug may help improve cancer treatment

"Angiotensin inhibitors are safe blood pressure medications that have been used for over a decade in patients and could be repurposed for cancer treatment," explains Rakesh K. Jain, PhD, director of the Steele Laboratory for Tumor Biology at MGH and senior author of the study. "Unlike anti-angiogenesis drugs, which improve tumor blood flow by repairing the abnormal structure of tumor blood vessels, angiotensin inhibitors open up those vessels by releasing physical forces that are applied to tumor blood vessels when the gel-like matrix surrounding them expands with tumor growth." Focusing on how the physical and physiological properties of tumors can inhibit cancer therapies, Jain’s team previously found that losartan improves the distribution within tumors of relatively large molecules called nanomedicines by inhibiting the formation of collagen, a primary constituent of the extracellular matrix…

Bone growth factor may increase benign tumors but not malignant cancer

Other papers in the September Neurosurgery report on a stent-assisted approach for difficult-to-treat brain aneurysms and a new software program to help in identifying and protecting critical areas during brain tumor surgery. BMP Linked to Increased Risk of Benign Tumors Dr. Nandan Lad of Duke University Medical Center and colleagues analyzed the risk of cancers and benign tumors in nearly 4,700 patients receiving BMP as part of spinal fusion surgery. …

Herding cancer cells to their death

If caught early, melanoma is relatively easy to treat. But in its late stages, it is a stubborn and deadly cancer. Until about a decade ago, patients survived only about seven months after starting treatment. Since then, therapies, such as vemurafenib, that specifically target signaling proteins essential to the proliferation and survival of melanoma cells have extended the lives of some patients. …
