RESUMEN
BACKGROUND: Gallbladder cancer (GBC) is associated with a high mortality rate. Asian American (AsA) are among the fastest-growing populations in the United States, yet little is known about the disparity of GBC within this cohort. This study identified trends in treatment and outcomes for GBC in a disaggregated fashion, specifically for this population. METHODS: A retrospective analysis of the National Cancer Database (NCDB) between 2010 and 2019 examining all patients treated for gallbladder cancer was performed. Basic demographic factors were identified for patients of Caucasian, African American, and disaggregated Asian subpopulations. Survival curves were used to identify differences in median overall survival, and a multivariate analysis was performed to determine which factors impact overall survival. RESULTS: A total of 1317 (5%) patients were of AsA origin. Median survival for the overall AsA population is 15.1 months compared with Caucasian (11.5 months) and African Americans (11.4 months) (p < 0.0001). Within the AsA groups, the Korean subpopulation had the lowest survival at 12.6 months, whereas Filipinos had the longest survival at 19.1 months (p < 0.0001). Patients of Filipino descent had the highest rate of surgical resection but lower chemotherapy utilization. Conversely, Korean patients had the highest utilization of multimodality therapy. Multivariate analysis demonstrated that belonging to Chinese, Filipino, or Indian ethnicity was associated with decreased risk of mortality. CONCLUSIONS: There are disparate differences in survival for patients with GBC between AsA groups. Socioeconomic, genetic, and epigenetic factors may influence these differences. Further research is needed to delineate the causes of this disparity.
RESUMEN
INTRODUCTION: Collaboration between the health care industry and surgeons is critical in modern medicine. Conflict of interest (COI) has the risk of introducing bias into research studies. We investigated the accuracy of self-disclosed COI for studies that researched the use of microwave ablation for liver metastasis. METHODS: A literature search identified studies that investigated the use of microwave ablation for liver cancer between 2016 and 2022. We utilized the Open Payments Database to query individual authors' financial contributions from the industry. The accuracy of the disclosure statement and financial contribution for each study and author was calculated. We compared the amount of financial contribution authors received based on the accuracy of their COI statement. RESULTS: Twenty-five studies of interest were identified. The mean number of authors was 8.24. A disclosure statement was present in 52% of studies. Of those, 28% had an incongruent disclosure statement. 9/25 (36%) of studies had a conflict of interest based on financial payments provided by industry. Overall, authors received an average of $440,483.41 (SD $1,889,375.34). We did not find a difference in the financial contribution's value based on the disclosure statement's accuracy (P = .55). CONCLUSIONS: Over a quarter of studies in our review of microwave ablation literature had discrepancies in the reporting of conflicts of interest, highlighting the need for improved reporting of potential conflicts of interest to protect the integrity of clinical research. Compared to other fields of surgery, we found a lower rate of undisclosed COI, suggesting that the scope of cancer-directed surgery may be more resistant to industry influence.
