Study evaluates effectiveness of 3 commonly used screening methods among South African women

The best approach to detecting cervical cancer in HIV-positive women living in research limited countries such as those in Sub-Saharan Africa combines commonly used testing methods tailored to local levels of development and medical infrastructure, according to a study by researchers from and the University of Witwatersrand in South Africa and the University of North Carolina.

Link between smoking intensity and bladder cancer prognosis

Smoking not only causes bladder cancer-it also affects its course, in that people who smoke more have greater likelihood of developing more aggressive and deadly disease. That is one of the conclusions of a new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society.

Clathrin protein may have a role in suppressing tumors

Newly published research by Indiana University structural biologist Joel Ybe and colleagues identifies a "topology switch" in the protein clathrin, the function of which may shed light on molecular processes involved in tumor suppression.

Fox Chase's OHCHD to fund community-based patient navigation services

Fox Chase Cancer Center's Office of Health Communications and Health Disparities (OHCHD) recently received a grant from the National Breast Cancer Foundation to fund community-based patient navigation services.

p53 activation suppresses malic enzyme expression and leads to senescence in pre-cancerous cells

It is perhaps impossible to overstate the importance of the tumor suppressor gene p53. It is the single most frequently mutated gene in human tumors. p53 keeps pre-cancerous cells in check by causing cells, among other things, to become senescent - aging at the cellular level. Loss of p53 causes cells to ignore the cellular signals that would normally make mutant or damaged cells die or stop growing.

TSC22D4 gene plays a key role in the onset of cachexia

Cachexia or wasting is a condition affecting up to 70 percent of cancer patients, depending on the type of cancer. It is characterized by a dramatic loss of body weight that is independent of food intake. Cachexia is seen particularly often and most pronounced in patients suffering from cancers of the digestive tract and the lungs.

Over-expression of NEK2 in cancer cells significantly enhances drug resistance

Increased NEK2 gene expression linked to increased drug resistance, faster cancer growth, and poorer patient outcome - The finding may improved diagnostic and prognostic tools for cancer care and could lead to improved cancer therapies

Viewpoints: Health law's 'sticker shock;' Changing Medicare eligibility age is not a simple solution

President Obama said a fair bit during the fiscal-cliff negotiations - speaking for 45 minutes in one 50-minute meeting, for example - but today let's zero in on the claim he kept repeating: "We don't have a spending problem. We have a health-care problem." For our money - and yours - those are two of the most remarkable sentences our Orator in Chief has ever strung together.

Novel system could allow broader screening for esophageal cancer, other conditions

Physicians may soon have a new way to screen patients for Barrett's esophagus, a precancerous condition usually caused by chronic exposure to stomach acid. Researchers at the Wellman Center for Photomedicine at Massachusetts General Hospital (MGH) have developed an imaging system enclosed in a capsule about the size of a multivitamin pill that creates detailed, microscopic images of the esophageal wall. The system has several advantages over traditional endoscopy.

Aggressive breast cancer’s metastasis molecular switch identified

Scientists at Weill Cornell Medical College have discovered the molecular switch that allows aggressive triple negative breast cancer cells to grow the amoeba-like protrusions they need to crawl away from a primary tumor and metastasize throughout the body. Their findings, published in Cancer Cell, suggest a novel approach for developing agents to treat cancer once it has spread.

Research roundup: Effectiveness of mobile clinics; Can more alternative medicine coverage save money?

Approximately 2,000 mobile health clinics in the U.S. have 6.5 million patient visits annually. Researchers analyzed data from nearly 6,000 patients from 2010 to 2012 from one program, to examine the clinical impact and cost-effectiveness.

Aggressive surveillance questionable for eye melanoma recurrence

Patients treated for primary choroidal or ciliary body melanoma may not always benefit from an aggressive surveillance strategy for the detection of metastatic disease, caution US researchers.

Beta blocker use linked to NSCLC patient survival

Beta blockers may boost survival in patients undergoing definitive radiotherapy for non-small-cell lung cancer, suggests research published in the Annals of Oncology.

Targeted prostate biopsies skew proportion of high-risk cases

Image-targeted biopsy of the prostate leads to a substantial increase in the proportion of prostate cores identified as high risk compared with standard transrectal ultrasound-guided biopsy, the results of a UK study indicate.

Smoking intensity affects course of bladder cancer

Smoking not only causes bladder cancer—it also affects its course, in that people who smoke more have greater likelihood of developing more aggressive and deadly disease. That is one of the conclusions of a new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society. The study also found that a panel of bladder cancer markers can predict which particular cases are at the highest risk for a fatal outcome.
