Sugar-sweetened beverage consumption increases endometrial cancer risk

Postmenopausal women who reported the highest intake of sugar-sweetened beverages had a 78 percent increased risk for estrogen-dependent type I endometrial cancer (the most common type of this disease). This association was found in a dose-dependent manner: the more sugar-sweetened beverages a woman drank, the higher her risk. "Although ours is the first study to show this relationship, it is not surprising to see that women who drank more sugar-sweetened beverages had a higher risk of estrogen-dependent type I endometrial cancer but not estrogen-independent type II endometrial cancer," said Maki Inoue-Choi, Ph.D., M.S., R.D., who led this study as a research associate in the Division of Epidemiology and Community Health of the University of Minnesota School of Public Health in Minneapolis. "Other studies have shown increasing consumption of sugar-sweetened beverages has paralleled the increase in obesity…

Link between allergies, increased risk of blood cancers in women

Notably, the study did not find the same association in men, which suggests a possible gender-specific role in chronic stimulation of the immune system that may lead to the development of hematologic cancers. The findings are published online ahead of the December print issue of the American Journal of Hematology. "To the best of our knowledge, ours is the first study to suggest important gender differences in the association between allergies and hematologic malignancies," wrote first author Mazyar Shadman, M.D., M.P.H., a senior fellow in the Clinical Research Division at Fred Hutchinson Cancer Research Center. …

Insight on cell migration, movement of cancer cells

Jordi Casanova, head of the "Morphogenesis in Drosophila" lab at IRB Barcelona and CSIC research professor, and Gaëlle Lebreton, postdoctoral fellow in the same group, have published a study performed using Drosophila melanogaster in the Journal of Cell Science. This work reveals that in a multiple movement, a single cell can act as the leader and can drag the rest with it. The scientists have studied the tracheal development of Drosophila in vivo and describe the morphological characteristics of the leading cell and provide molecular details about how it drives the movement. "Cancer researchers are keen to know how cells are organized to achieve migration and to form new capillaries to feed an expanding cancerous tumor," explains Gaëlle Lebreton, first author of the article. …

Oral drug may improve survival in men with metastatic prostate cancer

The study, published on Nov. 19, 2013, in the journal Clinical Cancer Research, adds long-term survival and safety data for the drug tasquinimod, a new candidate for treating advanced and recurrent prostate cancer. “While all subgroups in the clinical trial benefited from tasquinimod, those whose cancer metastasized to their bones had the greatest benefit in terms of delaying the time from the start of treatment to when the cancer progressed,” said lead author Andrew J…

Adult survivors of childhood cancer at risk of early aging

Researchers also found that frail health was associated with a greater risk for adult childhood cancer survivors of death and chronic disease. Being frail was defined by the presence of at least three of the following — weakness, self-reported exhaustion, physical inactivity, low muscle mass and slow walking speed. …

Higher than normal levels of Vitamin B12 may indicate cancer risk

To assess the association between high Cbl levels and risk of cancer of any type, Johan Arendt, BSc, of the Department of Clinical Epidemiology and the Department of Clinical Biochemistry of Aarhus University Hospital in Denmark, and colleagues used Danish Medical registries to review the records of 333,667 patients without cancer who had been referred for Cbl testing and to estimate the incidence of cancer in this population from 1998 to 2010. The researchers excluded patients who had a cancer diagnosis before the date of plasma measurement and those who were receiving Cbl therapy. They found that the risk of cancer overall increased with higher Cbl levels, especially during the first year after measurement and for those with levels > 800pmol/L. …

Ureteral injury during robot-assisted prostate surgery

Although rare, they found instances when the ureter — tubes that carry urine from the kidneys to the bladder — were cut and required repair. In each case, they identified patient characteristics that may forewarn such damage. The study was recently published in the Journal of Endourology. The study – drawing from Henry Ford Hospital’s experience with robot-assisted surgery removal of prostate cancer – was conducted in the context of a steady rise in robot-assisted prostatectomies in the U.S…

Obesity a major risk factor in developing basal-like breast cancer

In a study published online by the journal Breast Cancer Research and Treatment, a team led by Liza Makowski, assistant professor with the UNC Gillings School of Global Public Health and member of the UNC Lineberger Comprehensive Cancer Center, and Sneha Sundaram, PhD, a post-doctoral fellow in the Makowski Lab, outlined the biological mechanisms where obesity can create a favorable environment for the growth of basal-like breast cancer tumors. "Obesity is widespread and is one of the few risk factors for breast cancer that we may be able to control, hence our intention in this study was to better understand the molecular mechanisms and/or biomarkers of obesity-related basal like breast cancer that could impact disease prevention," said Dr…

Novel study charts aggressive prostate cancer

Investigators in the Cedars-Sinai Samuel Oschin Comprehensive Cancer Institute have made extensive progress in understanding the molecular mechanisms of disease progression. These results may help scientists better understand the prognosis of patients diagnosed with advanced prostate cancer. The study, published in the journal Cell Cycle and led by Dolores Di Vizio, MD, PhD, may ultimately lead to the development of new biomarkers for not only prognosis, but also a patient’s potential response to therapy. "One of the long-standing difficulties in treating men with advanced prostate cancer has been predicting the response to given therapies or treatments," said Di Vizio, associate professor in the Department of Surgery, Department of Pathology and Laboratory Medicine and Department of Biomedical Sciences. …
