Tubercle and lung tumour distinguish _'s symptom

Tubercle and lung tumour distinguish _'s symptom
Tubercle is a multi system granulation swollen disease with unidentified cause of disease. Lung cancer( With little cell cancer and gland cancer) particularly Can appear around lymph node shift swelling later period, it is very much important for the two to distinguish. Mainly distinguish through the following:
( 1) The lung tubercle one mainly infringes the lung door or mediastinal lymph node, there is little physical sign of lung. Lung cancer can cause the intersection of lung and piece or pneumonia, invade and pleura cause the thorax accumulate liquid by the intersection of lump and the intersection of blockade and bronchus, can lower the side respiration of the focus.
( 2) Lung X-ray, tubercle of disease display, have characteristic nature most, 90% - 95% show as lung door both sides symmetry swelling, some cases can accompany the enlargement of lymph nodes by the side trachea. The swelling lymph node realm can tell the round or potato shape in the clear area. The persons who only have enlargement of lymph nodes of one side lung door only account for 1% - 3%. Lung cancer accompanies the enlargement of lymph nodes of lung door to be most common with inner lump of the lung, accounts for 63.7%, only the enlargement of lymph nodes of lung door only accounts for 11.8%, dual side lung door lymph nodes only account for 4.9% big at the same time. The lung door lymph node and mediastinal enlargement of lymph nodes appear in 90.3% of the little cell cancer. About 3/4 of the lung cancer patients are shown as the single enlargement of lymph nodes of side lung door.
( 3) Fine to prop up the mirror to examine to distinguishing lung tubercle and lung cancer are of great importance. Examine negative patient, should try hard conduct TBLB or BAL living. If lymphocyte gt in the tubercle patient BALF; 28%, CD4 CD8 positive cell gt; 3,Can be regarded as tubercle activity one and index. The intersection of lung and the intersection of scale and cancer show as the intersection of mulberry fruit and kind or cauliflower mainly when being fine to prop up mirror, and cellule lung cancer become the intersection of tubercle and kind for polyp mainly. Cellule lung cancer is the most common, accounts for 87.8%. Mucomembranous swelling and increasing thick relatively scale's cancer commonly of gland cancer. Bronchus of lung cancer narrow mostly because tube wall own pathological change such as mucous membrane plump, soak and lump grow etc. lead to the fact, and lung tubercle is caused by outside and narrow much. Bronchus mirror brush, examine and live, examine, go on at the same time, can remedy deficiency that individual event check, raise and diagnose the positive rate greatly. Lung tubercle disease live, examine by mucous membrane only and lung live examine, paste up, examine, make a definite diagnosis of value.
( 4) It is helpful to distinguishing for the laboratory to check. Lung tubercle mainly changes enzyme to obviously raise for serum, and lung cancer is mainly apparent for CEA rise.
( 5) I stage lung tubercle can be healed by oneself in one year, but lung cancer is presented the going on and sent and grown, cellule lung cancer can increase rapidly in a short time.
