Drug combination therapy causes cancer cells to ‘eat themselves’

"It is still too premature to estimate when a clinical trial will open to further test this drug combination therapy, but we are now in the planning phase and encouraged by the results of these laboratory experiments," says Andrew Poklepovic, M.D., oncologist and member of the Developmental Therapeutics research program at VCU Massey Cancer Center and assistant professor in the Division of Hematology, Oncology and Palliative Care at VCU School of Medicine. …

Leadership void, not lack of money, slows efforts to address cervical cancer

"We focus on cervical cancer because it is likely the ‘low-hanging fruit’ opportunity to beat a cancer in this generation," said Beth Meyerson, a health policy expert at the IU School of Public Health-Bloomington. "We have the tools of HPV vaccination, screening and treatment; but uninsured women and women of color experience huge health disparities. This is the signal that we have a health system problem." Meyerson and her research colleagues conducted interviews with 15 professionals working in programs involving cervical cancer. …

Largest-ever study of male breast cancer treatment shows more mastectomy, less radiation than in females

"We know very little about male breast cancer since it comprises only 0.6 percent of all breast cancer, and nearly all therapy is based on female breast cancer studies. This study demonstrates that just as in women, men with early stage breast cancer have the same outcome with a mastectomy or a lumpectomy followed by radiation. In women, breast-conserving surgery is the standard and preferred treatment for the majority of women…

Half of prostate cancer patients in NC do not receive multidisciplinary care

Working with local hospitals across North Carolina, UNC researchers led by Ronald Chen, MD, MPH, assistant professor of Radiation Oncology in the UNC School of Medicine, and Paul Godley, MD, PhD, Professor in the Division of Hematology/Oncology — both members of the UNC Lineberger Comprehensive Cancer Center — surveyed patients about their decision-making process after a prostate cancer diagnosis. "Prostate cancer is a unique disease where there are multiple treatment options, ranging from active surveillance to surgical treatments to radiation treatments…

Researchers study epigenetic mechanisms of tumor metastasis for improved cancer therapy

The term epigenetics refers to the external modifications to DNA that turn genes "on" or "off." These modifications do not change the DNA sequence, but instead, they affect how cells read genes. The researchers propose that epigenetic and other changes mediate the development of cancer progenitor cells. These cells represent the early stage of cancer cell development and can grow rapidly to become full-fledged cancer. …

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…

Sedentary behavior linked to recurrence of precancerous colorectal tumors

The majority of colorectal cancers arise from precursors called colorectal adenomatous polyps, or colorectal adenomas, which can be removed during a colonoscopy. Although there is extensive evidence supporting an association between higher overall levels of physical activity and reduced risk of colorectal cancer, few studies have focused on the impact of sedentary behavior on colorectal cancer risk. "Sedentary behavior is emerging as a risk factor for poor health," said Christine L…

Researchers detail possible resistance mechanisms of colorectal cancer to bevacizumab (avastin)

"Think of it like damming a river. Bevacizumab can block the main flow, but then once a tumor’s need builds up behind this dam, water starts to flow around the blockage in the form of streams and tributaries. That’s like these other growth factors — eventually a tumor becomes able to use these tributaries of VEGF-C, VEGF-D and placental growth factor to supply itself with the ‘water’ it needs," says Christopher Lieu, MD, investigator at the CU Cancer Center and assistant professor of Medical Oncology at the University of Colorado School of Medicine…

Overlooked lymph nodes in rib cage have prognostic power for mesothelioma patients

The findings were presented October 28 at the 15th World Conference on Lung Cancer. Physicians look to lymph nodes to stage essentially all cancers, including mesothelioma. The presence or absence of metastatic cancer cells in lymph nodes affects prognosis and also typically dictates the optimal treatment strategy. But posterior intercostal lymph nodes, which are located between the ribs near the spine, have not been previously used to stage or guide treatment of malignant pleural mesothelioma or any other cancer. …

HPV strains affecting African-American women differ from vaccines

The findings, presented on Oct. 28, 2013, at the 12th annual International Conference on Frontiers in Cancer Prevention Research hosted by the American Association for Cancer Research, suggest that African-American women may be less likely to benefit from available HPV vaccines to prevent cervical cancer. HPV is a common sexually transmitted infection with more than 40 subtypes. The virus causes nearly all cases of cervical cancer, which begin as precancerous cervical abnormalities. …
