Objective:
Computed guided percutaneous biopsy of lung lesions is widely accepted as an effective and safe procedure for specific diagnose. The purpose of this study is to present the experience of an oncology center in the use of computed tomography (CT)-guided cutting needle biopsy as an effective procedure for adequate material and specific diagnose of lung lesions.
Subjects And Methods:
This study reports a retrospective analysis of 94 consecutive patients admitted in an oncologic center, reference in Brazil (Hospital do Câncer-AC Camargo), between 1996 and 2004, who were submitted to 97 CT guided cutting needle biopsy of pulmonary lesions. Informations of material adequacy and specific diagnose were studied.
Results:
In a total of 97 biopsies of lung lesions, 94 (96.9%) supplied adequate material for histological analyses with 71 (73.2%) as malignant lesions and 23 (23.7%) diagnosed as benign lesions and in 3 biopsies the material supplied was inadequate. The frequency of specific diagnosis was higher in both malignant and benign lesions with 63 (88.7%) cases and 20 (86.7%) cases respectively.
Conclusions:
CT-guided cutting needle biopsy is an effective procedure for adequate material and specific diagnostic for malignant and benign lung lesions.
