The prevalence of anal high-grade squamous intraepithelial lesions (HSIL), which precede anal cancer, is much higher in women living with HIV than previously reported, a multi-site, national study involving hundreds of patients has found. Conducted by researchers from the AIDS Malignancy Consortium, a National Cancer Institute-supported clinical trials group, the results call for new strategies to be developed for wider screening of women living with HIV, who have disproportionally higher rates of anal cancer compared to the general population of women.

A remarkable recent increase in the diagnosis of vocal-cord cancer in young adults appears to be the result of infection with strains of human papilloma virus (HPV) that also cause cervical cancer and other malignancies. Investigators from Massachusetts General Hospital (MGH) describe finding HPV infection in all tested samples of vocal-cord cancer from 10 patients diagnosed at age 30 or under, most of whom were non-smokers.
A new approach to analyzing prostate gland tissue may help address a major challenge in treating prostate cancer - determining which tumors are unlikely to progress and which could be life threatening and require treatment. In their report published in the journal Scientific Reports, Massachusetts General Hospital (MGH) investigators describe how cellular metabolites - proteins produced as the results metabolic processes - in apparently benign tissues from cancerous prostates not only can determine the grade and stage of the tumor but also can predict its risk of recurrence.
UCLA researchers have provided the first description of the structure of the herpes virus associated with Kaposi's sarcoma, a type of cancer.
The discovery answers important questions about how the virus spreads and provides a potential roadmap for the development of antiviral drugs to combat both that virus and the more common Epstein-Barr virus, which is present in more than 90 percent of the adult population and is believed to have a nearly identical structure.
In lab animals, a particle developed by UCLA, Stanford, NIH scientists awakens dormant virus cells and then knocks them out
Current anti-AIDS drugs are highly effective at making HIV undetectable and allowing people with the virus to live longer, healthier lives. The treatments, a class of medications called antiretroviral therapy, also greatly reduce the chance of transmission from person to person.
In a new research that comes via the American Cancer Society, it has been seen that over 40 percent of all cancers and nearly one in two cancer deaths can be prevented by incorporating simple lifestyle changes in daily routines.
The study titled, “Proportion and number of cancer cases and deaths attributable to potentially modifiable risk factors in the United States” was published in CA: Cancer Journal for Clinicians led by authors Farhad Islami, Ann Goding Sauer, Kimberly D Miller and colleagues.
Researchers at Albert Einstein College of Medicine have found that when human papillomavirus (HPV)-16 is detected in peoples' mouths, they are 22 times more likely than those without HPV-16 to develop a type of head and neck cancer. The study was published online today in JAMA Oncology and was led by Ilir Agalliu, M.D., Sc.D., and Robert D. Burk, M.D.
Digital Pathology is happening. While the advantages are evident and experts already predict a new generation of pathologists, only few laboratories and institutes have started planning and investing in fully digital work-flows. At the same time, the demand for professional online exchange and a convenient way of sharing educational or rare cases is growing with the aim to support a more precise and profound health care.
In a study in today's issue of Science, researchers at Albert Einstein College of Medicine, part of Montefiore Medicine, report that certain nerves sustain prostate cancer growth by triggering a switch that causes tumor vessels to proliferate. Their earlier research- which first implicated nerves in fueling prostate cancer- has prompted Montefiore-Einstein to conduct a pilot study testing whether beta blockers (commonly used for treating hypertension) can kill cancer cells in tumors of men diagnosed with prostate cancer.
Results from a new study conducted at the Institute of Cancer Research, London, suggests cancer cells that remain in the body after treatment, utilize the immune system of the body to wake themselves up and boost their growth.
Cancer cells can lay dormant in the body long after treatment, then turn deadly after a number of years. The aim of the study was to understand this process.
