PURPOSE: Could initial disappointing results of TBNA be reduced by ROSE? What about initial experience between broncoscopists (BR)?.
METHODS: We started LN-TBNA and ROSE with the aid of a technician to recognize lymphocytes (LFC) in the slide as a prove that the material was LN. In all cases we did at least 3 aspirations of LN containing LFC. TBNA was done for LN enlargement >12 mm in long axis in lung cancer setting. We considered a successful puncture one with LFC in a cytological exam confirmed by pathologist.
RESULTS: We had retrospectively analyzed 32 patients (pt) and 41 TBNA during the first year for one BR; the yields for successful (adequate) puncture was 78%. We divided in 3 periods his experience: in the the first 11 pt (19 TBNA) we had 68% of successful punctures (13/19); in the second group of 13 pt (14 TBNA) we obtained 85% (12/14) and in the last group of 8 pt (8 TBNA) 87.5 % of success (7/8 ). Later we compared results between two others BR (A and B) during 18 TBNA for each one (36 overall) and we divided our analysis in three series of 6 pts for BR A and BR B: in the first series BR A obtained 1/6 non (Idoneous) ID while BR B 2/6 non-ID. In the second BR A had 1/6 non ID while BR B 0/6 non ID. In the third BR A 0/6 non ID and BR B 1/6 non ID. In summary both BR after 18 LN-TBNA reported a success rate of 88% (16/18 samples).
CONCLUSION: In our experience LN-TBNA and ROSE gave very good diagnostic yield in un-experienced bronchoscopists and there are no significant differences between bronchospists working in the same conditions.
CLINICAL IMPLICATIONS: Considering the importance of TBNA in Lung cancer staging and diagnosis it’s important the most of Bronchoscopists learn it. ROSE is useful to get better results.
