2023 North America Conference on Lung Cancer (NACLC) - Posters and Abstracts-PP01.27 (Poster) Segmentectomy quality remains important in GGO dominant stage I lung cancer

Pdf Summary

The study evaluated the importance of anatomic segmentectomy in the surgical treatment of ground-glass opacity (GGO) dominant early lung cancer. The researchers conducted a retrospective review of patients with stage I non-small cell lung cancer (NSCLC) who underwent segmentectomy at a single institution between 2013 and 2019. The primary outcome measure was recurrence-free or overall survival, and secondary outcomes included pulmonary function test (PFT) results and lung plication after 3-6 months.<br /><br />The results showed that anatomic segmentectomy had a lower incidence of adverse outcomes and post-operative lung plication compared to non-anatomic segmentectomy. There was no significant difference between the two groups in terms of patient characteristics such as age, sex, comorbidities, tumor diameter, and location. However, the anatomic segmentectomy group had a higher proportion of complex segmentectomies and a larger number of mediastinal lymph node dissection stations.<br /><br />The study highlights the importance of evaluating the quality of segmentectomy procedures to reduce heterogeneity and improve outcomes. The researchers emphasize that not all segmentectomies are the same and that reproducibility and adherence to quality measures are essential. They reference previous studies that have suggested quality measures for segmentectomy, but the adherence rate was reported to be low.<br /><br />In conclusion, anatomic segmentectomy remains important in the surgical treatment of GGO dominant early lung cancer. This approach is associated with a low incidence of adverse outcomes and post-operative lung plication. The study highlights the need for institutional evaluation of segmentectomy quality to ensure reproducibility and improve outcomes.
