Surgical outcomes for non-small cell lung carcinoma by race and surgical facility types in the United States.

11167 Background: Successful outcomes of surgical treatment of cancer requires expertise and high-quality supportive services for surgical care. Previous studies have shown that case volume and availability of other in-house supportive services affect surgical outcomes. Latest studies have shown that this gap has now significantly reduced. Issues related to access, availability of funding for latest technologies and continuous medical education still exist and likely still impact the surgical outcomes. The objective of the study is to understand the impact of surgical center related factors on survival outcomes for cancer patients based on race and other demographic features. Methods: We conducted a retrospective analysis of patients diagnosed with Stage I-III Non-small cell lung cancer (NSCLC) between 2004 to 2020 using the National Cancer Database (NCDB). Patients were divided into 4 cohorts of NCDB assigned facility type (Community Cancer Program, Comprehensive Community Cancer Program, Academic/Research Program, Integrated Network Cancer Program). Racial and other demographic data was analyzed for each of the facility types. Differences in categorical variables were evaluated using a Chi-square test. Results: 298,393 adenocarcinoma and 129,144 squamous cell carcinoma patients underwent surgery for NSCLC between 2004-2020. 326,798 patients with clinical stages I-III were selected for the analysis. Most surgeries were performed at the academic/research programs and comprehensive community programs. Utilization of each facility type was uniform across all races. The 30-day mortality rate was lowest for the academic/research programs (Community Cancer Program 3.1%, Comprehensive Community Cancer Program 2.6%, Academic/Research Program 1.8%, Integrated Network Cancer Program 2.3%; p=0.000). 30-day mortality rate was higher for American Indian, Aleutian, or Eskimo racial subgroups amongst all age-groups at all the surgical facility types especially for Stage IIIB NSCLC (White: 6%, Black: 3.4%, American Indian, Aleutian, or Eskimo: 14.3%, p=0.006). For each race, the 30-day mortality rate was better at the academic/research programs. Females had lower 30-day mortality for all racial subgroups. Having private insurance was associated with the lowest 30-day mortality rate. This was noted for all races across all the facility types. Lower income status was associated with higher mortality rates across all facility types. This difference was statistically significant for white patients. Majority of patients had less than 10 days of length of stay at all the surgical facility types. Conclusions: Outcomes of NSCLC surgery are significantly better at academic/research programs where a higher number of procedures are performed and access to latest surgical technologies is available. Short-term mortality rates are higher for American Indian, Aleutian, or Eskimo racial subgroup.
