Preventing the Progression of Low-Risk Localized Prostate Cancers: A New Frontier

January 17, 2020 | Authored By: Howard L. Parnes, MD

Infographic: Percent of Prostate Cancer Cases by Stage

In the path toward understanding the development and ultimate prevention of prostate cancer, researchers are studying how to keep low-grade, early stage prostate cancer being monitored on Active Surveillance from progressing to disease that needs definitive treatment.

Attempts at prevention of prostate cancer have had mixed results. While both dutasteride and finasteride reduced the incidence of prostate cancer in large, randomized clinical trials, both agents were associated with an increase in high-grade, potentially more aggressive, cancers. Notably, long-term follow-up studies...

Taking Advantage of the Transportation Processes from Inside to Outside the Cell to Detect Cancer

As cancer researchers delve into the many molecular processes that guide cell life within the body, NCI is looking for ways to characterize and measure different substances in this process, with an eye to identifying who has cancer or who is at risk for the disease. One ongoing funding opportunity is promoting research on the isolation and characterization of extracellular vesicles (EVs) and their cargo for the discovery of biomarkers to predict cancer and cancer risk.

EVs are membrane-enclosed vesicles that are secreted by all cells. EVs are circulated in the blood and are readily...

New Onset Diabetes Cohort Sought to Unravel Complexities of Pancreatic Cancer Development

November 19, 2019, by DCP Staff

Pancreatic Cancer New Onset Diabetes: About 1 in 100 people with new onset diabetes are diagnosed with pancreatic cancer within 3 years of the diabetes diagnosis; 1 in 4 people diagnosed with pancreatic cancer were first diagnosed with diabetes.

The National Cancer Institute is leading a project to create a cohort of people who are newly diagnosed with diabetes in the hopes that this group, who are at increased risk of developing pancreatic cancer, provide the clues in their blood and tissues to unravel some of the unknowns about this highly fatal cancer. The New Onset Diabetes Study (NOD) will include 10,000 people ages 50 to 85 across the United States.

Diabetes is a disease that occurs when your blood glucose is too high. The hormone insulin, made by the pancreas, is responsible for regulating blood glucose, so having...

Cancer Prevention Science is Key to Making Progress Against Cancer

October 31, 2019, by DCP Staff

Cancer prevention interventions available today include: medications, lifestyle choices, treatments for infections, screening tests, vaccines, and surgery.

Cancer Prevention Science editors spoke with Deborah Winn, PhD, acting director of the NCI Division of Cancer Prevention, about cancer prevention and early detection research in the division and beyond.

Why is cancer prevention research important?

One important way to make sustained progress against cancer deaths is to prevent people from developing cancer in the first place. In 2019, there will be about 1.76 million people diagnosed with cancer in the United States.  By 2025, the estimate is that there will be 2.1 million people who get cancer...

TMIST (Tomosynthesis Mammographic Imaging Screening Trial), the large NCI screening study to learn about the best ways to find breast cancer in women who have no symptoms, is ramping up with 16,505 participants enrolled to date at 84 certified mammography clinics in the United States, Canada and Argentina.

The number of women and sites participating is likely to increase rapidly in the months ahead. Etta Pisano, MD, chief research officer at the American College of Radiology, and the principal investigator of TMIST, heads the efforts to get clinics involved.  “We have 15 approved...
