Japan’s Tokyo Li Ju to the hospital and Tokyo Institute of integrated clinical research, and other units recently developed jointly by urine found early colorectal cancer, which reduce colorectal cancer mortality great help. According to “Japan’s economic news” on the 20th, researchers in 250 patients with colorectal cancer study found that patients with colorectal cancer in the urine of two components acetyl spermine usually relatively high. Researchers believe that once a cell proliferation, will pass a lot of urine from diacetyl spermine, as long as patients in two urine acetyl spermine than three times higher than the normal level, can be suspected of having colorectal cancer. The patients with early colorectal cancer screening results showed that the urine test accuracy of 60%. Colorectal cancer screening is usually the first stool occult blood test, and then colorectal accurate endoscopic examination, the precision of around 60%. The researchers say that if the urine and stool screening test combination, the two inspection found no signs of cancer, do not need to carry out endoscopy, so as to reduce the burden on patients. Researchers plan to develop screening urine diacetyl spermine simple equipment, in addition to medical, could also be used to check whether colorectal cancer recurrence after surgery indications.
