Introduction: In aggregate, Asian patients have a higher incidence and mortality from gastric cancer (GC) than Non-Hispanic White (NHW) patients. However, there is a lack of data regarding outcomes among Asian-American subpopulations with GC., Methods: The National Cancer Database was used to identify patients with GC between 2004 and 2020. Asian patients were disaggregated by region, with a further subanalysis of Eastern Asians. Outcomes of interest included the initial localized/regional presentation versus metastatic disease and cancer care measures including undergoing surgical excision or resection for stages I-III, receiving guideline-concordant care, receiving delayed treatment (> 90 days for any treatment type), and overall survival. Outcomes were adjusted for patient/disease characteristics, treatment, and zip-code socioeconomic factors using logistic regression., Results: Among 182,811 patients with GC, 7.2% (n = 13,051) were classified as Asian. More than one-half of the Asian cohort was categorized as East Asian (n = 6,762, 50.1%), with Chinese patients compromising 44.0% (n = 2972) of this subcohort. East Asian patients had greater odds of presenting with nonmetastatic disease (odds ratio [OR] 1.59; P < 0.001), undergoing a curative-intent resection (OR 1.52; P < 0.001), and receiving guideline-concordant care (OR 1.26; P < 0.001) compared to NHW patients. Asians from outside of East, Southeast, and South Asia had increased odds of delayed treatment (OR 1.29, P = 0.024). Asians, in aggregate and by each subpopulation, had a lower mortality risk than NHW patients (P < 0.001)., Conclusions: Asian patients with GC have improved outcomes in aggregate compared to NHW patients, largely driven by the East Asian subpopulation. All Asian subpopulations demonstrated improved survival in comparison with NHW patients., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: Pancreatic carcinosarcomas (PCS) are rare aggressive biphasic malignancies with a poor prognosis. We aimed to improve the understanding of PCS by analyzing variables that influence the mortality of PCS patients., Methods: The Surveillance, Epidemiology, and End Results database was queried for cases of PCS from 1973 to 2016. Cases were analyzed for patient demographics, tumor characteristics, and surgical intervention. Kaplan-Meier and Cox regression analyses were applied to investigate the overall survival (OS) and prognostic factors., Results: Thirty-nine cases of PCS were identified along with the disease demographics and characteristics. The majority of patients had a regionally invasive or metastatic disease. There was a significant decrease in OS with the increase of the tumor extension. Conversely, surgery showed to improve OS in the crude analysis, including patients that underwent lymphadenectomy. In addition, the unadjusted Cox regression results showed decreased hazard ratios with a local disease versus distant metastasis and with cancer-directed surgery versus no surgery. Nevertheless, the adjusted Cox regression results revealed that metastatic disease was the only significant predictor of survival., Conclusions: This population-based study provides some insight to a very rare disease by analyzing 39 cases of PCS. Our finding suggests considering PCS as a nonsurgical disease and reserving surgery solely for patients with a localized disease in combination or after neoadjuvant therapy. Consequently, there is a need to further investigate novel therapies for this aggressive malignancy., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Background: Sentinel lymph node biopsy (SLNB) has shown promise in identifying subclinical nodal metastasis in patients with high-risk cutaneous squamous cell carcinoma. However, low metastasis rates may indicate that performing such a procedure in all patients may be unnecessary and costly., Materials and Methods: A decision model was developed to analyze costs and survival in patients with head and neck cutaneous squamous cell carcinoma based on their tumor and nodal metastasis staging and whether or not they received an SLNB. Incremental cost-effectiveness ratios were calculated based on the change in quality-adjusted life years (QALYs) and costs (US$) between the different options, with a threshold of $100,000 to determine the most cost-effective strategy. One-way, two-way, and probabilistic sensitivity analyses were performed to validate the results., Results: Not performing an SLNB results in 12.26 QALYs and a cost of $3712.98. Performing an SLNB resulted in a 0.59 decrease in QALYs and an increase in cost of $1379.58 for an incremental cost-effectiveness ratio of -2338.27. This trend remained the same across all tumor stages and remained consistent within most sensitivity analyses., Conclusions: In patients with head and neck cutaneous squamous cell carcinoma, the most cost-effective strategy is to not perform SLNBs, regardless of the patient's stage. Low rates of nodal metastasis in addition to low disease-specific death rates were the significant factors in this outcome. Increasing the sensitivity of SLNB would not impact this recommendation unless the rate of nodal metastasis was significantly higher., (Copyright © 2019 Elsevier Inc. All rights reserved.)
