Molecule that provides cellular energy found key to aggressive thyroid cancer

In an online issue of The Journal of Clinical Endocrinology and Metabolism, they identify Stearoyl-CoA desaturase 1 (SCD1) as an oncogenic enzyme that when inhibited and paired with another targeted drug effectively shuts down ATC cell growth and induces cell death. Investigators think that ATC relies on SCD1 to provide the fuel the cancer cells need to rapidly duplicate. The molecule provides this energy by promoting the cancer cell’s ability to generate certain fatty acids that are important for several biological processes such as cell division, survival, drug resistance and migration. …

Gene mutation drives cartilage tumor formation

In a study published in the Feb. 16, 2015, issue of the Proceedings of the National Academy of Sciences, Duke researchers and their colleagues revealed that mutations in the isocitrate dehydrogenase (IDH) gene contribute to the formation of benign tumors in cartilage that can be a precursor to malignancies. These benign tumors, known as enchondromas, are associated with severe pain, fractures, and skeletal deformities…

Cancer experience presents time for lifestyle changes in both survivors and family members

“A window of opportunity exists during the post-treatment transition period for oncology clinicians to reach out to patients and their caregivers who want to have a healthy start on life after cancer,” said Susan Mazanec, PhD, RN, AOCN, assistant professor at Case Western Reserve’s Frances Payne Bolton School of Nursing. Mazanec, also a nurse scientist at University Hospitals Case Medical Center’s Seidman Cancer Center, was lead investigator of the study, “Health Behaviors in Family Members of Patients Completing Cancer Treatment,” recently reported in Oncology Nursing Forum. Mazanec and colleagues surveyed and interviewed 50 patients diagnosed with breast, colorectal, head and neck, lung or prostate cancers and 38 caregivers within three week of a patient’s last treatment. The questions were designed to gauge family members’ intention, perceived benefit and confidence about eating a healthy diet, physical activity and smoking cessation…

Human stem cells repair damage caused by radiation therapy for brain cancer in rats

During radiation therapy for brain cancer, progenitor cells that later mature to produce the protective myelin coating around neurons are lost or significantly depleted, and there is no treatment available to restore them. These myelinating cells–called oligodendrocytes–are critical for shielding and repairing the brain’s neurons throughout life. …

Cancer treatment potential discovered in gene repair mechanism

If the laboratory findings are supported by tests in animal models, the breakthrough could hold the promise of increasing the effectiveness of radiation and chemotherapy in shrinking or even eliminating tumors. The key is to build up a “good” protein — p53-binding protein 1 (53BP1) — so that it weakens the cancer cells, leaving them more susceptible to existing cancer-fighting measures. The breakthrough detailed appeared in the Nov. 24 online edition of the journal PNAS (Proceedings of the National Academy of Sciences). …

Targeted treatment herceptin found to greatly improve long-term survival of her2-positive breast cancer patients — ScienceDaily

Published in the Journal of Clinical Oncology, the study found that Herceptin, when added to chemotherapy, improved 10-year survival from 75 percent with chemotherapy alone to 84 percent with the addition of trastuzumab. Additionally, results also demonstrated continued improvement of survival without cancer recurrence — the 10-year disease-free survival rate increased from 62 percent to 74 percent with the addition of trastuzumab. Although heart problems are recognized side effects of Herceptin, the incidence rate of such events was found to be about 3 percent and the majority of those patients recovered from the initial effects. “We have found that when Herceptin is used in combination with chemotherapy, a patient’s survival is significantly improved,” said Geyer, who serves as a senior scientific advisor to the NSABP and at Massey is the Harrigan, Haw, Luck Families Chair in Cancer Research, associate director for clinical research and member of the Developmental Therapeutics research program, as well as professor in the Division of Hematology, Oncology and Palliative Care at the VCU School of Medicine. …

Survey of the general population in France identifies knowledge gaps in the perception of lung cancer

Lung cancer management in recent years has improved patient outcomes because of screening, improved surgery and radiotherapy in early and locally-advanced stages of disease, new chemotherapies, validated maintenance therapy, and effective targeted therapies. However, fears or misperceptions about lung cancer may alter physician-patient communications and could delay lung cancer screening, diagnosis, or treatment…
