Tumor cells circulating throughout the body in blood vessels have long been feared as harbingers of metastasizing cancer — even though most free-floating cancer cells will not go on to establish a new tumor.
Men with type 2 diabetes are less likely to develop prostate cancer than patients without diabetes. However, the mortality rate is higher. Researchers of the German Center for Diabetes Research (DZD) from Tübingen and experts of Helmholtz Zentrum München and the Urology Department of Tübingen University Hospital were able to show that in the affected individuals the androgen receptor and the mitogenic forms of the insulin receptor were more strongly expressed. This could explain why patients with diabetes have a poorer prognosis for prostate cancer. The current results were published in the journals Molecular Metabolism and Endocrine Related Cancer.
Pancreatic cancer is a form of cancer associated with the highest mortality rates in the world. However, until now genetic changes that could explain the aggressiveness and early metastasis of this form of cancer had not been found. A team of researchers at the Technical University of Munich (TUM) and the German Cancer Consortium (DKTK) has now shown that those characteristics can be explained by specific gene amplifications which occur along various evolutionary pathways of the cancer. Based on this discovery, they have derived basic principles underlying the biology of this cancer type.
Among postmenopausal women with normal body mass index (BMI), those with higher body fat levels had an increased risk for invasive breast cancer, according to data presented at the American Association for Cancer Research Special Conference Obesity and Cancer: Mechanisms Underlying Etiology and Outcomes, held Jan. 27-30.
Tyumen doctors first in the world performed unique operation on implantation of radioactive sources of iodine in the treatment of a patient with pancreatic cancer, said Monday regional Department of health.
The latest generation of cancer treatments spring from the discovery that the human immune system is able to beat the disease. Like Dorothy in “The Wizard of Oz,” what research teams around the world have spent decades searching for was right in their own backyard all along.
