Preoperative Diagnosis of the Histological Structure of Adenocarcinoma of the Lung by CT-guided Percutaneous Lung Biopsy

We retrospectively compared the specimens of CT guided percutaneous lung biopsy with the specimens surgically resected later in 17 cases with small adenocarcinoma of the lung to investigate the possibility of preoperative prediction of the Noguchi type pathological classification. The coincidence rate was 41.2%(7/17). It was considered difficult to guess the Noguchi type of small adenocarcinoma of the lung preoperatively by CT guided percutaneous lung biopsy. In this study, one resected specimen contained linearly-arranged fibrosis and fibroblasts suggesting the sequelae of lung biopsy. It seemed to be important to pay attention to the possibility of fibrosis resulting from biopsy in classifying the Noguchi type.
