Everolimus for the Treatment of Advanced Pancreatic Ductal Adenocarcinoma (PDAC)

Introduction: PDAC is a lethal malignancy with a clear unmet need; almost all patients fail 1(st), 2(nd), and 3(rd) line multi-agent cytotoxic chemotherapy. The mammalian target of rapamycin (mTOR) has been identified as a key signaling node enhancing tumor survival and drug resistance in PDAC; hence, it is considered a promising therapeutic target. Areas covered: We comprehensively reviewed the evidence from preclinical and phase I and II clinical trials, based on the authors\u27clinical experience and a PubMed, Cochrane library, Embase, and Google Scholar search everolimus + pancreatic cancer. Expert opinion: Everolimus has not demonstrated efficacy in PDAC; however, an mTOR inhibitor in combination with stroma-targeted therapies may be a promising area to explore in clinical trials

Prostate Cancer Disparities in Metastatic and Treatment Status for Hispanic Americans Based on Country of Origin Compared to Non-Hispanic Whites Using the National Cancer Database.

INTRODUCTION: Among Hispanic-American (HA) men, prostatic cancer (PCa) accounts for nearly one-quarter of the total cancer burden. We sought to identify differences in PCa presentation and treatment status for HA subgroups based on country/region of origin. MATERIAL AND METHODS: Using the National Cancer Database, we identified patients with histologically confirmed prostate adenocarcinoma with reported race/ethnicity, clinical staging, Gleason score ≥ 6, and PSA level at diagnosis from 2010 to 2016. HAs were divided into 4 subgroups: Mexican, Puerto Ricans, Cubans, and Central/South Americans. Non-Hispanic White (NHW) men were used as a reference group. Statistical analysis was derived from the Kruskal-Wallis test for continuous variables and χ RESULTS: A total of 428,829 patients were included, with 5625 (1.3%) classified as HA. Within the Hispanic group, 2880 (51.2%) were Mexican, 999 (17.8%) Puerto Rican, 477 (8.5%) Cuban, and 1269 (22.6%) South/Central American. Mexican men presented with higher median PSA, more Gleason 8 to 10 disease, and higher rates of metastatic presentation compared to NHW and other HA subgroups (all, p \u3c .01). Metastatic rates over the study period for Mexican, Puerto Rican, Cuban, and South/Central Americans were 6.4 (±1.2), 5.3 (±3.0), 3.2 (±2.0), and 4.6% (±1.7), respectively (p = .01). Treatment rates were 89.1, 89.6, 92.4, and 89.3% for Mexican, Puerto Rican, Cuban, and South/Central Americans, respectively (p = .19). Mexican men had higher odds of initial metastatic presentation (OR: 1.32; 95%CI: 1.07-1.63, p = .01) but lower odds of receiving treatment (0.68; 0.55-0.85, p \u3c .01). CONCLUSION: Men of Mexican origin presented with more advanced PCa when compared to NHW and other Hispanic subgroups. Our results warrant further investigation into potential biological factors affecting Hispanic patients as well as the identification of treatment barriers for this vulnerable population

Impact of Aspirin Use on Outcomes in Patients With Hepatocellular Cancer: A Nationwide Analysis.

BACKGROUND: Despite the use of new immunotherapies, hepatocellular carcinoma (HCC) has a poor survival rate. Through multiple molecular mechanisms, aspirin (ASA) has demonstrated a reduced incidence of HCC, however, the impact of long-term ASA use on in-hospital outcomes has not been studied. METHODS: We queried the National Inpatient Sample (NIS) database from 2016 to 2020 to identify patients with HCC. Patients were stratified into two groups, based on long-term ASA use. Information was collected regarding patient demographics, Elixhauser comorbidities, interventions, etiology, and decompensations of liver disease. Outcomes studied included sepsis, shock, acute kidney injury (AKI), intensive care unit (ICU) admission, and in-hospital mortality. The association between long-term ASA use and outcomes was studied using multivariate analysis. RESULTS: A total of 224,735 patients were included in the study. Of them, 18,835 (8.4%) patients were on long-term ASA. The majority of the patients with ASA use were White (61.3%), men (78.2%), and aged \u3e 65 years old (68.8%). Patients in the ASA group had a higher incidence of non-alcoholic steatohepatitis (NASH) and decreased rates of hepatic decompensation than those not on ASA. Patients with ASA use had lower incidence of sepsis (2.76% vs. 3.54%), shock (4.86% vs. 8.23%), AKI (30.9% vs. 33.4%), ICU admission (3.88% vs. 7.4%) and in-hospital mortality (5.18% vs. 9.87%). After adjusting for confounding factors, ASA use was associated with a 30% lower risk of in-hospital mortality (adjusted odds ratio (aOR): 0.70, 95% confidence interval (CI): 0.60 - 0.82, P \u3c 0.001). ASA users also had 21% lower odds of developing shock (aOR: 0.79, 95% CI: 0.67 - 0.94, P = 0.007) and 31% lower odds of requiring ICU admission (aOR: 0.69, 95% CI: 0.54 - 0.78, P \u3c 0.001). CONCLUSIONS: Our study noted that patients on long-term ASA use had better in-hospital outcomes such as mortality, shock, and ICU admissions compared to non-ASA users. These findings are of interest, and further randomized clinical trials confirming the benefits of ASA in improving outcomes in HCC patients need to be conducted

Evaluation of the safety and effectiveness of direct oral anticoagulants and low molecular weight heparin in gastrointestinal cancer-associated venous thromboembolism

A total of 144 patients were prescribed anticoagulation, in which 106 fulfilled inclusion criteria apixaban (27.3%), rivaroxaban (34.9%) and enoxaparin (37.7%), and 38 were excluded. Patients median age was 66.5 years at GICA diagnosis and 67 years at CAVTE event, with 62% males, 80% Caucasian, 70% stage IV, pancreatic cancer (40.5%), 30% Khorana Score (≥ 3 points), and 43.5% on active chemotherapy. Sixty-four percent of patients completed anticoagulation therapy (range 1 to 43 mo). Recurrent VTE at 6 mo was noted in 7.5% (n = 3), 6.8% (n = 2) and 2.7% (n = 1) of patients on enoxaparin, apixaban and rivaroxaban, respectively (all P = NS). MB at 6 mo were 5% (n = 2) for enoxaparin, 6.8% (n = 2) for apixaban and 21.6% (n = 8) for rivaroxaban (overall P = 0.048; vs LMWH P = 0.0423; all other P = NS). Significant predictors of a primary or secondary outcome for all anticoagulation therapies included: Active systemic treatment (OR = 5.1, 95%CI: 1.3-19.3), high Khorana Score [≥ 3 points] (OR = 5.5, 95%CI: 1.7-17.1), active smoker (OR = 6.7, 95%CI: 2.1-21.0), pancreatic cancer (OR = 6.8, 95%CI: 1.9-23.2), and stage IV disease (OR = 9.9, 95%CI: 1.2-79.1).University of Arizona Hematology and Medical Oncology Fellowship programOpen access journalThis item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.
