The findings are published in The Journal of Pathology. The American Cancer Society estimates over 134,000 people will be diagnosed with colon cancer in 2014, despite the expanded screening processes now available. …
A simple blood test could identify those with hypercalcaemia, prompting doctors to investigate further. The research, published in the British Journal of Cancer, analysed the electronic records of 54,000 patients who had elevated levels of calcium and looked at how many of them went on to receive a cancer diagnosis. Dr Fergus Hamilton, who led the research from the Centre for Academic Primary Care at the University of Bristol, said: “All previous studies on hypercalcaemia and cancer had been carried out with patients who had already been diagnosed with cancer — hypercalcaemia was seen as a late effect of the cancer. “We wanted to look at the issue from a different perspective and find out if high calcium levels in blood could be used as an early indicator of cancer and therefore in the diagnosis of cancer.” Analysis of the data from 54,000 patients found that in men, even mild hypercalcaemia (2.6-2.8 mmol l−1) conferred a risk of cancer in one year of 11.5 per cent. …
“Tumors located at the base of the skull are particularly challenging to treat due to the location of delicate anatomic structures and critical blood vessels,” said neurosurgeon Clark C. Chen, MD, PhD, UC San Diego Health System. “The conventional approach to excising these tumors involves long skin incisions and removal of a large piece of skull. …

The surprising new findings, described in the December issue of the journal Cancer Research, show that in cell culture and animal models carbon monoxide (CO) can both prevent tumor growth in prostate and lung cancers and can amplify the effectiveness of chemotherapy 1,000-fold — while sparing noncancerous tissue from chemo’s sometimes debilitating side effects. "We found that in small, carefully controlled doses, CO not only mimicked the effects of chemotherapy agents by blocking proliferation of cancer cells, but also amplified the toxic effects of the chemotherapy drugs doxorubicin and camptothecin to accelerate cancer cell death," says senior author Leo Otterbein, PhD, an investigator in the Transplant Institute in BIDMC’s Department of Surgery and Associate Professor of Surgery at Harvard Medical School. "Importantly and rather unique is that CO also helped to protect normal tissue from chemotherapy, which is an unfortunate side effect of the treatments." The new discovery appears to hinge on CO’s ability to switch the metabolic state of cancer cells so that tumors essentially work themselves to death…
Women with certain mutations in their BRCA1 or BRCA2 genes are at increased risk for breast cancer. However, if a woman who comes from a BRCA family tests negative for her family-specific BRCA mutation, her risk for breast cancer is considered to be the same as someone in the general population, according to the National Cancer Institute. This study, however, suggests that it may not always be true. "We found that women who test negative for family-specific BRCA2 mutations have more than four times the risk for developing breast cancer than the general population," said Gareth R. …
The November Neurosurgery also reports on unusual language side effects in patients undergoing electrical brain stimulation for obsessive-compulsive disorder (OCD), and presents plans for a pilot study of a new vaccine therapy for patients with aggressive brain cancers called gliomas.

"Our study investigated how resveratrol and radiotherapy inhibit the survival of melanoma cells," said Michael Nicholl, MD, assistant professor of surgery at the MU School of Medicine and surgical oncologist at Ellis Fischel Cancer Center in Columbia, Mo. "This work expands upon our previous success with resveratrol and radiation in prostate cancer. …
Malignant germ cell tumours arise in sperm- or egg-forming cells and usually occur in the reproductive organs, the testes or ovaries. The cancerous tumours are seen in patients of all ages, both in childhood and adulthood. Although many patients do well after treatment, current chemotherapy treatments can have severe long-term side effects, including hearing loss and damage to the kidneys, lungs and bone marrow. For some patients, outcomes remain poor and testicular cancer continues to be a leading cause of death in young men…
