FDG-PET/CT shows promise for breast cancer patients younger than 40

Assessing if and how far breast cancer has spread throughout the body is what doctor’s refer to as staging. Most women nowadays are diagnosed at earlier stages, meaning stage 1 or 2 of possible 4 stages (stated Christopher Riedl, MD). Current National Comprehensive Cancer Network (NCCN) guidelines consider systemic FDG-PET/CT staging for only stage III breast cancer patients. …

Fertility preservation option for young boys with cancer

The research, conducted by the Medical Center’s Wake Forest Institute for Regenerative Medicine (WFIRM) under the direction of Anthony Atala, M.D., institute director, gives boys who have a high risk of becoming sterile the option to “bank” a small piece of testicular tissue prior to treatment. “The average survival rates for childhood cancer are around 80 percent, but a side effect of some treatments can be permanent sterility,” said Thomas W. McLean, M.D., a pediatric cancer specialist, who co-leads the experimental biological bank with Hooman Sadri-Ardekani, M.D., Ph.D., a male infertility specialist at WFIRM. …

Genetic test would help cut bowel cancer spread, research suggests

In a major study, Dr Ian Frayling from Cardiff University’s School of Medicine and researchers from the University of Exeter’s Medical School assessed the effectiveness of introducing a UK-wide screening program for a genetic condition known as Lynch Syndrome. Lynch syndrome is caused by changes in genes which check the spelling in DNA. The condition increases the risk of people developing cancer, particularly bowel cancer and cancers of the womb and ovaries later in life. …

Endoscopists recommend frequent colonoscopies, leading to its overuse, study finds

“Our study shows that a high percentage of follow-up colonoscopies are being performed too early, resulting in use of scarce health care resources with potentially limited clinical benefit,” said Thomas D. Sequist MD, MPH, BWH Division of General Medicine and Primary Care, senior study author…

Customizing chemotherapy in lung cancer: New phase II data reported

In a randomized phase II study, researchers showed that patients whose lung cancers expressed low levels of an enzyme called thymidylate synthase experienced a greater benefit from treatment with the combination of pemetrexed and cisplatin than those whose tumours expressed high levels. “Thymidylate synthase is one of the proteins that is targeted by pemetrexed which is the most widely used chemotherapeutic regimen in the treatment of non-squamous NSCLC,” explains study author Professor Myung-Ju Ahn, from the Section of Hematology-Oncology at Samsung Medical Center, Sungkyunkwan University School of Medicine, Seoul, Korea. “In this study, we tried to evaluate whether expression of thymidylate synthase is a predictive factor for response to pemetrexed plus cisplatin chemotherapy compared with gemcitabine plus cisplatin in non-squamous cell lung cancer patients.” In terms of response rate and progression-free survival, the clinical benefits of the pemetrexed combination compared to other regimen were more prominent in those patients who expressed low levels of the molecule, Ahn said…

French studies measure benefits of colorectal cancer screening

Dr Vanessa Cottet from INSERM Unit� 866 in Dijon, France, and colleagues studied the region of C�te-d’Or, where a registry has been collecting data on adenomas since 1976. They wanted to evaluate the rate of diagnosis of adenomas before and after the initiation of a screening program using fecal occult blood testing that began in 2003…

Study questions accuracy of lung cancer screens with FDG-PET technology in some geographic regions

Histoplasmosis and other fungal diseases are linked to fungi that are often concentrated in bird droppings and are found in soils. The study by investigators at Vanderbilt University and the Tennessee Valley Healthcare System-Veterans Affairs was led by Vanderbilt first author Stephen Deppen, Ph.D., and principal investigator Eric Grogan, M.D., MPH, and appeared in the Sept. 24 issue of JAMA. …

Positron emission tomography (PET) combined with fludeoxyglucose F18 (FDG) is currently recommended for the noninvasive diagnosis of lung nodules suspicious for lung cancer…

New cancer drug target involving lipid chemical messengers

Youhai Chen, PhD, MD, and Svetlana Fayngerts, PhD, both researchers in the department of Pathology and Laboratory Medicine at the Perelman School of Medicine, University of Pennsylvania, and colleagues report that TIPE3, a newly described oncogenic protein, promotes cancer by targeting these pathways. Lipid second messengers play cardinal roles in relaying and amplifying signals from outside the cell to its interior and outer membrane. …
