Insights

Discontinuing rapid on-site evaluation (ROSE) during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) due to COVID-19 did not negatively impact cytopathology quality. The direct-to-cell block approach proved acceptable for maintaining cancer patient care during the pandemic.

Area of Science:

  • Pulmonology
  • Cytopathology
  • Oncology

Background:

  • Rapid on-site evaluation (ROSE) is standard practice for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).
  • The COVID-19 pandemic necessitated the discontinuation of ROSE at our institution, shifting to a direct-to-cell block approach.
  • This change prompted an investigation into its effects on cytopathology quality.

Purpose of the Study:

  • To evaluate the impact of discontinuing ROSE on the cytopathology quality of EBUS-TBNA procedures.
  • To determine if the direct-to-cell block method is a viable alternative to ROSE during the pandemic.

Main Methods:

  • Analysis of 1903 EBUS-TBNA cases from 734 patients, comparing those with ROSE (1097 cases) to those without ROSE using a direct-to-cell block approach (806 cases).
  • Clinical and cytology data were statistically analyzed using SAS software (version 9.4).
  • Key metrics included specimen adequacy, diagnostic yield for malignancy, and other conditions.

Main Results:

  • Biopsy adequacy was slightly lower in the ROSE group (0.936 times less likely to be satisfactory), but this difference was not statistically significant (P = 0.785).
  • The inadequacy rate for EBUS-TBNA was marginally higher with ROSE, though also not statistically significant.
  • Proportions of biopsies diagnostic for malignancy and other conditions showed significant differences between the ROSE and no-ROSE groups (P = 0.036 and P = 0.012, respectively).

Conclusions:

  • Discontinuing ROSE and adopting a direct-to-cell block approach did not compromise cytopathology quality.
  • This modified practice is acceptable, particularly during the COVID-19 pandemic, addressing challenges like social distancing and staff shortages.
  • The findings support the continued use of the direct-to-cell block method when ROSE is not feasible, ensuring uninterrupted cancer patient care.
