Show moreIntroduction: Superior sulcus tumors (SSTs) are uncom-mon, and their anatomical location can make treatment challenging. We analyzed late outcomes of patients with SST treated with concurrent chemoradiotherapy followed by surgical resection (trimodality) in a single tertiary institution.Methods: Patients with non-small cell SSTs, who under-went trimodality therapy between 2002 and 2017, were selected from a prospective institutional surgical database. Patients were uniformly staged with 18F-fluorodeox-yglucose-positron emission tomography, computed tomog-raphy scan of the chest and upper abdomen, and brain imaging. Patients undergoing resection of the lung plus chest wall were grouped as limited SST and those needing extensive resections (e.g., including the vertebral body) as extended SST. Kaplan-Meier survival analysis was per-formed to determine difference in survival. Multivariate Cox regression was used to identify prognostic factors.Results: A total of 123 patients were identified with a me-dian follow-up of 4.9 years (interquartile range: 1.6-8.9 y). The 90-day postoperative mortality and morbidity (Clavien-Dindo grades III-V) were 6.5% and 21.1%, respectively. Patients with a radical resection (R0: 92.7%) had better survival (p = 0.002), as did those who had major pathologic response (73%) (p = 0.001). Ten-year overall survival (OS) and disease-free survival were 48.1% and 42.6%, respec-tively. There were no differences in 90-day mortality (p = 0.31) and OS (p = 0.79) between extended SST and limited SST patients.Conclusions: In patients with SST, trimodality resulted in a 10-year estimated OS and disease-free survival of 48.1% and 42.6%, respectively, which were improved after radical resection (R0) and major pathologic response. Survival for limited and extended resections was comparable, and distant relapse was the main pattern of failure. Better sys-temic treatments are therefore needed. (c) 2023 The Authors.

Show moreObjectives: Data on national patterns of care for patients with superior sulcus tumors (SST) is currently lacking. We investigated the distribution of surgical care and outcome for patients with SST in the Netherlands. Material and methods: Data was retrieved from the Dutch Lung Cancer Audit for Surgery (DLCA-S) for all patients undergoing resection for clinical stage IIB-IV SST from 2012 to 2019. Because DLCA-S is not linked to survival data, survival for a separate cohort (2015-2017) was obtained from the Netherlands Cancer Registry (NCR). Results: In the study period, 181 patients had SST surgery, representing 1.03% (181/17488) of all lung cancer pulmonary resections. For 2015-2017, the SST resection rate was 14.4% (79/549), and patients with stage IIB/III SST treated with trimodality had a 3-year overall survival of 67.4%. 63.5% of patients were male, and median age was 60 years. Almost 3/4 of tumors were right sided. Surgery was performed in 20 hospitals, with average number of annual resections ranging from < 1 (n = 17) to 9 (n = 1). 39.8% of resections were performed in 1 center and 63.5% in the 3 most active centers. 12.7% of resections were extended (e.g. vertebral resection). 85.1% of resections were complete (R0). Morbidity and 30-day mortality were 51.4% and 3.3% respectively. Despite treating patients with a higher ECOG performance score and more extended resections, the highest volume center had rates of morbidity/mortality, and length of hospital stay that were comparable to those of the medium volume (n = 2) and low-volume centers (n = 1). Conclusion: In the Netherlands, surgery for SST accounts for about 1% of all lung cancer pulmonary resections, the number of SST resections/hospital/year varies widely, with most centers performing an average of < 1/year. Morbidity and mortality are acceptable and survival compares favourably with the literature. Although further centralisation is possible, it is unknown whether this will improve outcomes. Show less
