ASCO Announces New Way to Treat Colorectal Cancer
WASHINGTON — June 24, 2018
American scientists have developed a new technique to detect colorectal cancer at an earlier stage.
"A new study has found that a test that identifies circulating tumor cells (CTCs) present in the bloodstream can detect colorectal cancer at an early stage, with accuracy ranging from 84 to 88%." said an American Society of Clinical Oncology (ASCO) statement.
This study was conducted at Chang Gung Memorial Hospital, Taoyuan, Taiwan. The researchers enrolled 620 people over the age of 20.
“Our study is important because there is still some reticence among patients to use stool-based tests or have an invasive exam like colonoscopy to detect colorectal cancer,” said lead study author Wen-Sy Tsai, MD, PhD, assistant professor, Linkou Chang Gung Memorial Hospital, Taipei, Taiwan. “Our results may point to a solution for people who are reluctant to get an initial screening colonoscopy or are not compliant in returning stool-based test kits that they get from their doctors.”
The blood samples were processed using an assay that captures rare CTCs, such as those found in early-stage cancer. The results of these assays were then compared in a blinded analysis with the colonoscopy results.
"The specificity values were 97.3%, indicating a very low (less than 3%) probability of a false-positive result. The study results showed that sensitivity ranged from 77% for detection of CTCs in pre-cancerous lesions, to 87% for stage I-IV cancers." said in statement.
Studies results will be presented at the upcoming 2018 Gastrointestinal Cancers Symposium in San Francisco, California.
Earlier the scientists announced that they have found a way of beating the breast cancer.
