Gene likely to promote childhood cancers pinpointed by researchers

“We and others have found that Lin28b — a gene that is normally turned on in fetal but not adult tissues — is expressed in several childhood cancers, including neuroblastoma, Wilms’ tumor and hepatoblastoma, a type of cancer that accounts for nearly 80 percent of all liver tumors in children,” said Dr. Hao Zhu, a principal investigator at CRI, and Assistant Professor of Pediatrics and Internal Medicine at UT Southwestern Medical Center. “In our study, we found that overproduction of Lin28b specifically causes hepatoblastoma, while blocking Lin28b impairs the cancer’s growth…

New way to more accurately detect cervical cancer in women

The American Cancer Society predicts that this year in the United States, more than 12,100 women will be diagnosed with cervical cancer, and roughly 4,220 women will die of the disease. Newer Pap tests and HPV screening more accurately identify pre-cancerous cellular changes that potentially develop into cervical cancer…

Shingles vaccine remains effective after chemotherapy

Researchers examined the electronic health records of more than 21,000 Kaiser Permanente patients in Southern California who were 60 years of age and older and received chemotherapy between January 2007 and December 2012. Researchers found that those patients who were previously vaccinated with zoster vaccine were 42 percent less likely to develop shingles following chemotherapy. In addition, no vaccinated patients underwent hospitalization for shingles, while six unvaccinated patients were hospitalized with the disease, according to the study…

3-in-1 optical skin cancer probe

Researchers from the University of Texas at Austin’s Cockrell School of Engineering have now developed a probe that combines into one device three unique ways of using light to measure the properties of skin tissue and detect cancer. The researchers have begun testing their 3-in-1 device in pilot clinical trials and are partnering with funding agencies and start-up companies to help bring the device to dermatologists’ offices. The researchers describe the skin cancer probe in a new paper published in the journal Review of Scientific Instruments, from AIP Publishing. Skin cancers of all types are the most common forms of cancer in North America, and melanoma, the most deadly form of skin cancer, is one of the leading causes of cancer death, killing nearly 10,000 people every year in the United States. …

Blood and saliva tests help predict return of HPV-linked oral cancers

“There is a window of opportunity in the year after initial therapy to take an aggressive approach to spotting recurrences and intensively addressing them while they are still highly treatable,” says Joseph Califano, M.D., professor of Otolaryngology — Head and Neck Surgery, member of the Johns Hopkins Kimmel Cancer Center, and medical director of the Milton J. Dance Jr. Head and Neck Center at the Greater Baltimore Medical Center. “Until now, there has been no reliable biological way to identify which patients are at higher risk for recurrence, so these tests should greatly help do so,” he adds. …

Pain and itch may be signs of skin cancer

The study, published online by JAMA Dermatology on July 23, 2014, found that nearly 36. 9 percent of skin cancer lesions are accompanied by itching, while 28.2 percent involve pain. Non-melanoma skin cancers — specifically, basal cell carcinoma and squamous cell carcinoma — are more likely than melanoma to involve itch or pain, the study found. “The study highlights the importance of a simple bedside evaluation for the presence and intensity of pain or itch as an easily implementable tool for clinicians in evaluating suspicious skin lesions,” concluded the study. …

Five daily portions of fruit and vegetables may be enough to lower risk of early death

These results conflict with a recent study published in BMJ’s Journal of Epidemiology and Community Health suggesting that seven or more daily portions of fruits and vegetables were linked to lowest risk of death. There is growing evidence that increasing fruit and vegetable consumption is related to a lower risk of death from cardiovascular disease and cancer. However, the results are not entirely consistent. …

Drug may aid multiple myeloma patients who suffer from low platelet counts

In a July 25, 2014, article in The Journal of Clinical Investigation online, the researchers show that when the proteasome, which is a protein complex that breaks down the proteins that regulate cellular processes, is pharmaceutically inhibited platelet production in human and mice cells was blocked. Platelets are cells that bind together and help induce clotting to stop bleeding. The researchers also show that Fasudil, a drug approved for use outside of the United States but not in this country, restored platelet counts in adult mice whose proteasome activity had been suppressed by administering bortezomib and by knocking out a particular gene. …

Common, hard-to-treat cancers: Potential new targeted therapies

“Cancer relapses and treatment resistance have always been among the most daunting challenges in cancer care,” said press briefing moderator Gregory Masters, MD, FACP, ASCO Expert and a medical oncologist at the Helen F. Graham Cancer Center in Newark, Delaware. “The good news is that genomic medicine is helping to overcome these challenges by revealing new ways to target a cancer cell’s inner workings. …
