Crioterapia em tumores infiltrantes da árvore traqueobrônquica

ABSTRACTCryotherapy is a bronchoscopic method used to destroy endobronchial tumors. It has very good results in exophytic lesions and doubtful results in infiltrative tumors.To study his action on infiltrative tumors we have reviewed 11 tumors treated by cryotherapy between 17/09/93 and 22/07/94. The tumors were squamous cell carcinoma and morphologically infiltrative.The study group was as follow: 11 male patients whose age ranged from 59 to 82 years (average-71.9). We carried out 33 treatments (average-3/patient). The endoscopic method was the usual and we used endoscopic standards to classify the results.ResultsThe partial or total desobstruction was not achived in any case. There were no complications related to the method.ConclusionCryotherapy was unsuccessful in restoring bronchial patency in 100% of the cases.We think that the biological tumoral behaviour is the explanation for this results
