Cancer increasing as babyboomers age

"The increase in the number of older adults, the association of cancer with aging, the workforce shortage, and the financial stressors across the health care system and family networks all contribute to a crisis in cancer care that is most pronounced in the older population," wrote three members of the Institute of Medication Committee on Improving the Quality of Cancer Care: Addressing the Challenges of an Aging Population in an editorial published In JAMA, The Journal of the American Medical Association. "Often caregiving falls to a family member who is also aging," noted Mary D. Naylor, PhD, FAAN, RN, the Marian S. Ware Professor in Gerontology and the Director of the NewCourtland Center for Transitions and Health and a member of the committee…

Early stages breast cancer could soon be diagnosed from blood samples

With a New York University Cancer Institute colleague, the researchers report in an upcoming Clinical Chemistry (now online) that the mixture of free-floating blood proteins created by the enzyme carboxypeptidase N accurately predicted the presence of early-stage breast cancer tissue in mice and in a small population of human patients. "In this paper we link the catalytic activity of carboxypeptidase N to tumor progression in clinical samples from breast cancer patients and a breast cancer animal model," said biomedical engineer Tony Hu, Ph.D., who led the project. "Our results indicate that circulating peptides generated by CPN can serve as clear signatures of early disease onset and progression." The technology is not yet available to the public, and may not be for years. More extensive clinical tests are needed, and those tests are expected to begin in early 2014…

Female doctors twice as likely to screen low-risk women for cervical cancer

Female family physicians are twice as likely to order the HPV test (in addition to screening for cervical cancer through pap smears) for low-risk women aged 30-65 than their male counterparts, according to the findings published in the Journal of the American Board of Family Medicine. …

Online course improves physicians skill level for detecting skin cancer

The INFORMED study is believed to be the first of its kind to track physician practice patterns as an outcome of a skin cancer detection training course. INFORMED stands for INternet curriculum FOR Melanoma Early Detection. Key findings of 54 physicians who took the course: • Scores for diagnosing and managing all skin cancer lesions increased 10 percent. …

Tobacco myths persist 50 years after US Surgeon General warned Americans of smoking dangers

"Since 1964, smoking rates have dropped by more than half as a result of successful education, legislative and smoking cessation efforts," said Lewis Foxhall, M.D., vice president for health policy at MD Anderson. "Still, lung cancer remains the number one cancer killer and the leading preventable cause of death in the United States." With the approaching 50th anniversary of the Surgeon General’s Report, Foxhall and other MD Anderson experts urge the public to take a proactive stance against this pervasive health issue by gaining insight on current tobacco issues including information that disproves the following myths. Tobacco Myth #1: Almost no one smokes any more. …

Study finds more accurate method to diagnose pancreatic cancer

"Pancreatic cancer can be difficult to diagnose because of subtle differences that distinguish between healthy tissue, cancerous tissue and tissue that is atypical, or suspicious," said Lester Layfield, MD, professor and chair of the MU School of Medicine’s Department of Pathology and Anatomical Sciences. "Our goal was to find a way to make a more accurate and reproducible diagnosis." Because of the pancreas’ location within the body, no routine screening methods, such as mammography for breast cancer, exist for detecting pancreatic cancer. If a physician suspects a patient may have pancreatic cancer, a biopsy of the pancreatic tissue is taken through a minimally invasive technique called endoscopic ultrasound-guided fine-needle aspiration…

Customizing treatments for deadly prostate cancer with tumor genomics

"Men with castration-resistant prostate cancer have abysmal survival rates, typically living an average of two years once hormone therapies fail," says Manish Kohli, M.D., a Mayo Clinic oncologist and principal investigator of the Prostate Cancer Medically Optimized Genome-Enhanced Therapy (PROMOTE) study. Dr. Kohli says the poor prognosis for men with this cancer highlights the need for studies like PROMOTE, which seek to match new targeted drugs with the genomic characteristics of individual patients’ tumors. Several new therapies have recently been approved by the FDA for use in treating castration-resistant prostate cancer, offering new hope for men with this disease. …

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…

Earlier onset of puberty in girls linked to obesity

Published online Nov. 4, the multi-institutional study strengthens a growing body of research documenting the earlier onset of puberty in girls of all races. "The impact of earlier maturation in girls has important clinical implications involving psychosocial and biologic outcomes," said Frank Biro, MD, lead investigator and a physician in the Division of Adolescent Medicine at Cincinnati Children’s Hospital Medical Center. "The current study suggests clinicians may need to redefine the ages for both early and late maturation in girls." Girls with earlier maturation are at risk for a multitude of challenges, including lower self-esteem, higher rates of depression, norm-breaking behaviors and lower academic achievement. …
