ABSTRACT
BACKGROUND:
Sampling of ≥10 lymph nodes during lobectomy for non-small cell lung cancer (NSCLC) was a previous surveillance metric and potential quality metric of the American College of Surgeons Commission on Cancer. We sought to determine guideline adherence and its relationship to hospital lobectomy volume within The Society of Thoracic Surgeons General Thoracic Surgery Database.METHODS:
Participant centers providing elective lobectomy for NSCLC within The Society of Thoracic Surgeons General Thoracic Surgery Database (2012-2019) were divided into tertiles according to annual volume. Average hospital nodal harvest of ≥10 nodes per lobectomy defined the primary outcome. Univariable analysis compared average patient and operative characteristics between the participant centers. Multivariable logistic regression was used to determine independent factors associated with average clinical center nodal harvest of ≥10 nodes.RESULTS:
Median annual lobectomy volume was 6.2, 19.9, and 42.7 for low-, medium-, and high-volume participant centers. Among 305 centers and 43 597 patients, 5.6% of lobectomies occurred in low-volume centers, 24.0% in medium-volume centers, and 70.4% in high-volume centers. Average rates of ≥10 nodes per lobectomy were excised in 44.0% of low-volume centers, 70.6% of medium-volume centers, and 75.2% of high-volume centers (P < .001). On multivariable analysis, average nodal excision of ≥10 nodes was strongly associated with medium-volume (odds ratio, 2.94; CI, 1.57-5.50, P < .01) and high-volume (odds ratio, 3.82; CI, 1.95-7.46; P < .001) participant centers.CONCLUSIONS:
Although higher center volume and increased nodal harvest are associated, 25% of high-volume centers average a rate of <10 lymph nodes per lobectomy for NSCLC. Low nodal yield may underestimate stage, with implications for adjuvant therapy and long-term survival.
