Chinese experts focus on early, accurate and fine lung cancer, and the original diagnosis greatly improves the rate of early diagnosis

Lung nodule detection rate increased from 77.3% to 89.3%, early lung cancerdiagnosisthe correct rate reached 94.7%, pure mill glass density nodule syllatatry judgment accuracy of 93%Reporters learned on the 22nd, the Navy Military Medical University Second Affiliated Hospital (Shanghai Long March Hospital) Led by Professor Liu Shiyuan radiation diagnostic team, the construction of early screening of lung cancer, early diagnosis imaging system, formed an early lung cancer diagnosis norms and standards, put forward a series of pioneering theory and original diagnostic methods, so as to improve the rate of early diagnosis of lung cancer, reduce mortalityit is known that after surgical removal of early lung cancer, the five-year survival rate is close to 100%Liu Shiyuan introduced, unfortunately, many patients appear in the hospital symptoms of discomfort only to find lung cancer, at this time, about 80% of patients have lost the opportunity to operate, less than 2% of lung cancer at the time of detection at an early stageLiu Shiyuan,of, told reporters that for more than a decade, the task force focused on the difficulty of diagnosis and treatment of lung cancer, high misdiagnosis rate, low diagnosis rate and other world-wide problems, carried out a forward-looking exploration and attackIt is reported that the relevant research won the first prize of scientific and technological progress in Shanghai in 2019early diagnosis is closely related to the prognosis of lung cancer, the task force took the lead in the Shanghai area to carry out large-scale multi-center early lung cancerscreening, the first screening of high-risk groups for low-dose CT screening, the first to support multi-center research of the excavatable, expandable lung cancer case database, to achieve case data sharing"Some people do a CT examination of their lungs, get a report that is lung nodules, often take a hand and foot, think they have lung cancer." Liu Shiyuan said that lung nodules are not necessarily lung cancerHow can you tell if the nodules found are not lung cancer? Radiologists can dig out more diagnostic information from the imageteam and artificial intelligence company jointly developed artificial intelligence model, the first artificial intelligence lung nodule detection model for chest and CT related to the examination, not only can detect the needle-size millimeter-scale nodules, but also can mark the location, density of the nodules, to avoid the risk of missed diagnosiswhether pure-grinding glass nodules need surgery has always been a difficult problem facing surgery, the task force to build a variety ofaccurateprediction model, the comprehensive use of a variety of methods to judgeAccording to statistics, the accuracy of the method is more than 93%The team also innovatively used the target probe, through the injection of contrast agent imaging system, like the "mirror", so that malignant tumors quickly "present", to help doctors achieve "precision out of bad molecules."it is understood that Liu Shiyuan team of lung conynation testing technology, diagnosis and differential diagnosis and lung cancer screening and other original results in Shanghai, hundreds of major hospitals in The country have been widely used, the results of the relevant research were introduced into the British Thoracic Association guidelines and the Canadian lung nodule report analysis system, for the benefit of patients around the worldin recent years, Liu Shiyuan led the team to develop five Chinese expertsconsensus, formed two industry norms and standards, approved national invention patents 7, utility model patents 3Liu Wei Source: China News Network
