Abstract

This study aimed to retrospectively determine the feasibility and safety of computed tomography (CT)-guided intrathoracic and bone re-biopsy for patients with non-small cell lung cancer (NSCLC). Seventeen patients underwent CT-guided intrathoracic or bone re-biopsy for the determination of epidermal growth factor receptor (EGFR) T790M mutation and/or programmed cell death-ligand 1 (PD-L1) expression. The characteristics of each lesion, success rate of analyses, and complications were investigated. Specimens from 16 out of the 17 patients were adequate for evaluation of EGFR T790M mutation and/or PD-L1 expression. The mean diameter of the lesions was 40 mm, the mean procedural time was 24 minutes, and the median number of punctures was 2. There were no significant differences in lesion characteristics and success rates between CT-guided intrathoracic and bone re-biopsies. No serious complications occurred. Both CT-guided intrathoracic and bone re-biopsies for patients with NSCLC were feasible and safe.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
