The scientists say when activated, one protein, called the short form, stops glioblastoma cells from replicating their DNA, and the other, called the long form, prevents cell division if the DNA has already been replicated, explains Rebecca Riggins, PhD, assistant professor of oncology at Georgetown Lombardi. The study was posted online Dec…
A gene normally involved in the regulation of embryonic development can trigger the transition of cells into more mobile types that can spread without regard for the normal biological controls that restrict metastasis, the new study shows. …
An investigational drug discovered and being developed by Pfizer Inc., palbociclib targets a key family of proteins (CDK4/6) responsible for cell growth by preventing them from dividing. Results of the multi-year phase 2 study showed a significant increase in progression-free survival (PFS0 for patients with advanced breast cancer that was estrogen receptor positive (ER+), HER2-negative (HER2-), who were given a combination of the standard anti-estrogen treatment letrozole and palbociclib, compared to letrozole alone. …

It is estimated that the seven “high-risk” HPV types found in the nonavalent vaccine can potentially prevent over 90 percent of cervical cancers and a similarly high number of other HPV-associated cancers of the vulva, vagina, anus, penis, and some head and neck cancers. “As the healthcare providers for women who suffer from cervical and lower genital tract cancers, members of the SGO have always been advocates for the primary prevention of cervical and other HPV-related cancers,” said SGO President Richard R…
Chronic pancreatitis (CP) is an inflammatory disease that over time leads to loss of function of the pancreas and manifests with intractable pain, malabsorption and diabetes. While medical management and pain control are the initial approaches to CP, some patients need to undergo more invasive procedures to relieve ductal pressure in the pancreas. If those measures fail, surgical options can include total removal of the pancreas (total pancreatectomy, TP) or the Whipple procedure to remove part of the pancreas. Total pancreas removal produces diabetes because insulin-secreting cells are removed…
And once the sleep was lost, there was no getting its positive effect back by allowing extra rest later. In “Recovery Sleep Does Not Mitigate the Effects of Prior Sleep Loss on Paclitaxel-Induced Mechanical Hypersensitivity in Sprague-Dawley Rats,” a preclinical study published in Biological Research for Nursing, restricted sleep among rats led to worse reactions to PAC, associated with painful, debilitating peripheral neuropathy of the hands and feet that may persist long after therapy is completed. According to the study, “How poor sleep sets the stage for adverse outcomes among people diagnosed with cancer is not entirely understood…
The study, “Volumetric Breast Density Improves Breast Cancer Risk Prediction,” was presented during the 2014 San Antonio Breast Cancer Symposium. …

They found that patients were rarely involved in the decision to be referred for investigation and that reasons for referral tended to be couched in non-specific terms rather than ‘cancer investigation’, even when the patient was on a cancer-specific pathway. The National Institute for Health and Care Excellence (NICE) referral guidelines emphasise that the patient should be involved in the decision-making process and be informed of the reasons for referral…
