A two-year study of nearly 190, 000 girls and women, finds that Gardasil, the human papillomavirus (HPV) vaccine made by Merck & Co, does not trigger autoimmune disorders such as lupus, rheumatoid arthritis, type 1 diabetes and multiple sclerosis. The results are published in the Journal of Internal Medicine. Study lead author Dr Chun Chao, a research scientist at the Kaiser Permanente Department of Research & Evaluation in Pasadena, California, said in a statement released on Friday, that: "This kind of safety information may help parents with vaccination decisions." ""These findings offer some assurance that among a large and generalizable female population, no safety signal for autoimmune conditions was found following HPV4 vaccination in routine clinical use, " said Chao. Gardasil is a "quadrivalent" vaccine because it helps protect against 4 types of HPV.
Oral HPV infection is more common among men than women, explaining why men are more prone than women to develop an HPV related head and neck cancer, according to a study presented at the Multidisciplinary Head and Neck Cancer Symposium, sponsored by AHNS, ASCO, ASTRO and SNM. Human papillomavirus, or HPV, has recently been linked to some types of head and neck cancer that are becoming more prominent in the United States, mostly among men. Patients infected with oral HPV type 16 have a 14 times greater risk of developing one of these cancers, which usually form on the tonsils and at the back of the tongue. The correlation between HPV and oral cancer was only established in 2007, so it is not well understood how to detect or prevent these cancers. Researchers sought to understand how prevalent oral HPV is in the U.
Independent of other factors, such as smoking history and HPV status, matted lymph nodes appear to signal increased chance of oropharyngeal cancer spreading to other parts of the body Researchers at the University of Michigan Health System have found a new indicator that may predict which patients with a common type of throat cancer are most likely have the cancer spread to other parts of their bodies. Patients with oropharyngeal squamous cell carcinoma who had "matted" lymph nodes - nodes that are connected together - had a 69 percent survival rate over three years, compared to 94 percent for patients without matted nodes, according to a study published online ahead of print publication in Head & Neck. The oropharynx is an area that includes the back of the tongue, soft palate, throat and tonsils.
Not only are relatively few Americans screened for cancer, but there are considerable disparities between ethnic and racial groups in the country, says a new report issued by NCI (National Cancer Institute) and the CDCF (Centers for Disease Control and Prevention). The authors added that screening rates are especially low among Hispanic and Asian Americans. The report is called "Cancer Screening in the United States - 2010." The Healthy People 2020 target of 81% screening rate for breast cancer was not met in 2010, which reached 72.4%. The achieved rate for cervical cancer was 83% compared to the 93% target, and colorectal cancer was 58.6% compared to a target of 70.5%. Below are some highlighted data about screening rates among Asians and Hispanics in 2010: Asians 64.1% - breast cancer 75.
Researchers in Family and Community Medicine at Thomas Jefferson University recently found that obesity was linked to higher rates of prostate cancer screening across all races/ethnic differences and lower rates of cervical cancer screening, most notably in white women. Their study on the role of obesity in cancer screening rates for prostate, cervical as well as breast and colorectal cancers across race/ethnicity and gender is examined in the current issue of the Journal of Obesity. "Numerous studies have suggested that obesity constitutes an obstacle to cancer screening, but a deeper examination also considering the role of race/ethnicity and gender in the equation has not been done before, " said Heather Bittner Fagan, MD, FAAFP MPH, lead author and associate professor, Thomas Jefferson University and director of Health Services Research, department of Family and Community Medicine, Christiana Care Health System.
