Feasibility of computed tomography-guided core needle biopsy in producing state-of-the-art clinical management in Chinese lung cancer.

ABSTRACT:

Background

A satisfactory biopsy determines the state-of-the-art management of lung cancer in this era of personalized medicine. This study aimed to investigate the suitability and efficacy of computed tomography (CT)-guided core needle biopsy in clinical management.

Methods

A cohort of 353 patients with clinically suspected lung cancer was enrolled in the study. Patient factors and biopsy variables were recorded. Epidermal growth factor receptor (EGFR) gene mutations and echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) rearrangement were detected in tumor specimens. Adequacy of biopsic obtainment for clinical trial screening and tissue bank establishment were reviewed.

Results

Overall diagnostic accuracy of malignancy achieved 98.5%. The median biopsy time of the cohort was 20 minutes. In patients with non-small cell lung cancer (NSCLC), 99.3% (287/289) were diagnosed as specific histologic subtypes, and two patients (0.7%) were determined as NSCLC not otherwise specified (NOS). EGFR mutations were analyzed in 81.7% (236/289) of patients with NSCLC, and 98.7% (233/236) showed conclusive results. EML4-ALK gene fusion was tested in 43.9% (127/289) of NSCLC patients, and 98.4% (125/127) showed conclusive results: 6.4% (8/125) of those had gene fusion. Ninety-six NSCLC patients participated in clinical trial screening and provided mandatory tumor slides for molecular profiling. Pathological evaluation was fulfilled in 90 patients (93.8%); 99.4% (320/322) of patients with malignancy provided extra tissue for the establishment of a tumor bank.

Conclusions

CT-guided core needle biopsy provided optimal clinical management in this era of translational medicine. The biopsic modality should be prioritized in selected lung cancer patients.

Project description:ObjectiveTo evaluate the feasibility and diagnostic performance of ultrasound (US)-guided fine-needle aspiration cytology and core-needle biopsy (US-FNAC/CNB) for the diagnosis of laryngo-hypopharyngeal masses.Materials and methodsThis was a single-center prospective case series. From January 2018 to June 2019, we initially enrolled 40 patients with highly suspicious laryngo-hypopharyngeal masses on laryngoscopic examinations. Of these, 28 patients with the mass involving or abutting the pre-epiglottic, paraglottic, pyriform sinus, and/or subglottic regions were finally included. These patients underwent US examinations with/without subsequent US-FNAC/CNB under local anesthesia for evaluation of the laryngo-hypopharyngeal mass.ResultsOf the 28 patients who underwent US examinations, a laryngo-hypopharyngeal mass was identified in 26 patients (92.9%). US-FNAC/CNB was performed successfully in 25 of these patients (96.2%), while the procedure failed to target the mass in 1 patient (3.8%). The performance of US caused minor subclinical hematoma in 2 patients (7.7%), but no major complications occurred. US-FNAC/CNB yielded conclusive results in 24 (96.0%) out of the 25 patients with a successful procedure, including 23 patients with squamous cell carcinoma (SCC) and 1 patient with a benign mass. In one patient with atypical cells in US-FNAC, additional direct laryngoscopic biopsy (DLB) was required to confirm SCC. Among the 26 patients who received US-FNAC/CNB, the time from first visit to pathological diagnosis was 7.8 days. For 24 patients finally diagnosed with SCC, the time from first visit to the initiation of treatment was 25.2 days. The mean costs associated with US-FNAC/CNB was $272 under the Korean National Health Insurance Service System.ConclusionUS-FNAC/CNB for a laryngo-hypopharyngeal mass is technically feasible in selected patients, providing good diagnostic performance. This technique could be used as a first-line diagnostic modality by adopting appropriate indications to avoid general anesthesia and DLB-related complications.
