Lung tumour is diagnosed to find the new index
Content of peculiar growth factor of serum tumour secreted according to lung tumour cells that it is reported, can assist and judge whether this focus is benign or malignant, it is positive to measure the correct rate and is higher than PET (send specially) Wait for the image to learn to check. Third army medical university large the intersection of level ground and the intersection of hospital and the intersection of thoracic surgery and the the intersection of friend and the intersection of Professor and latest find of research group, publish on the academic magazine " clinical lung cancer " of American authority recently.
It is the key to treating lung cancer to make a definite diagnosis of early. It is a clinical difficult problem that the common isolatism lung is little and focal and good to determine the nature all the time malicously, because is small, the patient does not have obvious symptom, will not usually seek medical advice voluntarily, thus delay treating the opportunity. Isolatism the intersection of lung and little focus include the intersection of isolatism and the intersection of lung and tubercle and maos of hyaline the intersection of shadow and two mainly, diameter smaller than centimetre of the intersection of isolatism and the intersection of lung and little focuses exceed 60% as malignant, diameter loud malignant possibility the larger. Send the intersection of top grade and image learn, check malignant isolatism to be lung little focus low in detection rate, need finding a kind of representative index with higher sensitiveness badly.
Tan QunYou research group is in the course of looking for index of determining the nature of little focus of lung, transfer the sight to peculiar growth factor of serum tumour gradually. Peculiar growth factor of serum tumour is by a kind of peculiar protein factor that the cover secretes in tumour cell blood vessel, found at first by the scientist of our country several years ago. The research group is to in the diagnosis of several dozen lung little focus patients who are collected at random in earlier stage, determine peculiar growth factor of each patient's serum tumour as to the content first, then make the intersection of thorax and mirror, lay the intersection of focus and part, excise, make icy pathology, check in the skill. Through the quantized contrast, the research group finds, content of peculiar growth factor of serum tumour is the higher in patient blood final proof one, the greater the focus presents malignant probability, and little focus patient's postoperative content of peculiar growth factor of serum tumour of malignant isolatism lung can be reduced progressively.
Further discover, relative benign tumour cells, peculiar growth factors of serum tumour that malignant tumour cells secrete are more, pass the determination of the content of peculiar growth factor of serum tumour in one of final proof of blood, small and focal diagnosis of determining the nature of very effective auxiliary lung, its sensitivity is up to 90.0%, specificity can reach 79.5% as 87.4%, accuracy rate of diagnosis for predicting rate 74.5%, negative for predicting rate 69.2%, positive.
