While the rates of colorectal cancer among patients older than 50 years old has decreased in recent years due to screening, it has increased by 22 percent among those under the age of 50
Researchers at Boston Medical Center, in collaboration with Northwestern University, are using nanocytology imaging technology to create an effective and inexpensive way to screen for colorectal cancer among young adults. Developed by Dr Vadim Backman at Northwestern, nanocytology, allows scientists to visualise particles much smaller than a normal microscope and identify cancer risk markers accurately. The test will be low-cost and can be performed in a primary care setting.
Colorectal cancer is the second leading cause of cancer death in the country. While the rates of colorectal cancer among patients older than 50 years old has decreased in recent years due to screening, it has increased by 22 percent among those under the age of 50, which could place a burden on the health care system over the next decade.
"This is an entirely new issue that we are facing in the medical community, and we're not entirely sure why it's happening," said lead researcher, Dr Hemant Roy, section chief of gastroenterology at BMC. "What we do know is there needs to be a way to identify those patients who are at high risk and ensure they get the treatment they need."
The study is viewing rectal swabs and looking for advanced adenomas, markers of potential colorectal cancer. Patients who have advanced adenomas are referred to a specialist for a colonoscopy to test for colorectal cancer.
"We're aiming to create a test that won't take much time to conduct, will be far less invasive for patients than a colonoscopy, and most importantly, can save lives," said Roy.
The research is part of the R33 Cancer Moonshot Project, and is a three year US$1.5 million grant from the National Cancer Institute. Once researchers create this test and achieve quality goals, they will begin a clinical trial, which can then lead to regulatory approval and launch in clinical practice. In total, 860 patients will be recruited from Boston Medical Center with the analysis done at Northwestern University.
