ABSTRACT
BACKGROUND:
Molecular testing has become a more frequent necessity in NSCLC management. Using next-generation sequencing, multiple targets for therapy can be identified with small amounts of nuclear material. The authors evaluated the performance of robotic-assisted bronchoscopy in acquiring tissue that meets pre-analytic criteria for PD-L1 immunohistochemistry and/or next-generation sequencing. MATERIALS ANDMETHODS:
Patients with a diagnosis of primary lung cancer identified through robotic bronchoscopy were retrospectively reviewed. Pathology reports were assessed for results of molecular testing and detection of programmed death-ligand 1 (PD-L1). An independent pathologist evaluated each specimen type (smears, cell block, tissue biopsy, and/or touch prep) to determine whether each tissue type would meet pre-analytic criteria for attempting next-generation sequencing and/or PD-L1 immunohistochemistry.RESULTS:
Seventy-eight patients with primary lung were reviewed. By independent pathologic assessment of cytological smears, cell block, biopsy, and/or touch preparations, 72% of samples were found to be adequate for molecular and PD-L1 testing. Preanalytic adequacy (%) for next-generation sequencing (NGS) and PD-L1 staining was determined based on specimen type cytological smear 48.6% for NGS; cell block 14.3% for NGS and 32.9% for PD-L1; biopsy 29.2% for NGS and 62.5% for PD-L1; and touch prep 61.4% for NGS.CONCLUSION:
Robotic-assisted bronchoscopy yielded samples that met preanalytic criteria for molecular testing in 72% of cases. These results support the use of robotic-assisted bronchoscopy for both the diagnosis and molecular testing of early-stage lung cancer.Palavras-chave
