Abstract Background Cabozantinib is indicated for hepatocellular carcinoma (HCC) following first-line (1L) sorafenib, but the 1L standard has shifted to immuno-oncology (IO)-based regimens. This study evaluated real-world outcomes among patients with advanced HCC receiving second-line (2L) cabozantinib following 1L therapies, including newer regimens. Patients and Methods US claims data were used to identify adults with advanced HCC initiating 2L cabozantinib monotherapy (index date). Patients were stratified into three 1L treatment cohorts: IO monotherapy/IO + IO combination therapy; IO + non–IO combination therapy; or tyrosine kinase inhibitor (TKI) monotherapy. Real-world time to treatment discontinuation (rwTTD), real-world time to next treatment or death (rwTNTD), real-world overall survival (rwOS), and cabozantinib dosing were assessed collectively and by cohort. Adverse events were assessed before/after cabozantinib initiation. Results Among 148 patients who received 2L cabozantinib, 28 were in the IO monotherapy/IO + IO combination therapy cohort, 54 in the IO + non–IO combination therapy cohort, and 66 in the TKI monotherapy cohort. Median rwTTD among all patients was 3.2 months; median rwTNTD was 7.6 months; 12-month rwOS rate was 61.6%. There were no significant differences in these outcomes among the three cohorts. Overall, 44.6% of patients initiated 2L cabozantinib at 60 mg/day, of whom 39.4% required a dose reduction; 37.8% initiated at 40 mg/day, of whom 16.1% had a dose reduction. Adverse event rates were similar before/after cabozantinib initiation. Conclusions Cabozantinib shows consistent effectiveness and safety in the 2L HCC setting following prior TKIs or IO-based regimens in real-world clinical practice. These findings may inform 2L treatment decisions.

Abstract The landscape of Alzheimer's disease (AD) and related dementias (ADRD) diagnosis is evolving rapidly, driven by advances in disease understanding, biomarker tools, and disease‐modifying therapies. Modern diagnostic approaches emphasize biological precision, early detection, and dynamic frameworks that adapt to treatment‐induced changes in disease biology. These frameworks enable opportunities for personalized interventions—encompassing pharmacological and non‐pharmacological strategies—and for enhanced clinical trial design. However, implementing these advancements globally is influenced by diverse cultural, infrastructural, and regulatory factors. The 2024 Alzheimer's Association International Conference Advancements: Modernizing Diagnosis, held in Japan, provided a unique platform to explore these global dynamics, particularly from an Asian perspective. This article highlights key discussions from the conference, exploring the role of biomarker‐based diagnostic frameworks in shaping the future of AD/ADRD research, diagnosis, and treatment. We highlight regional challenges and successes and emphasize ethical considerations and practical strategies needed to ensure equitable access to diagnostic and therapeutic innovations. Highlights Advances in biomarkers are reshaping Alzheimer's disease diagnosis and treatment. Modern diagnostic frameworks highlight biological precision, early detection, and dynamic frameworks. The 2024 Alzheimer's Association International Conference Advancements: Modernizing Diagnosis explored challenges and opportunities in global biomarker implementation. The conference explored geographic‐specific impacts, focusing on Asia.

Ischemic monomelic neuropathy (IMN) is a rare peripheral neuropathy caused by limb ischemia and subsequent nerve degeneration, typically manifesting with unilateral pain, paresthesia, and numbness without overt signs of limb ischemia. This case report describes a 59-year-old female with extensive peripheral artery disease who developed IMN in her right lower extremity following an acute, intraoperative in-sheath thrombosis during a right femoral endarterectomy and external iliac artery stent placement, a rare etiology distinct from the more commonly reported associations with bypass surgery or hemodialysis access. Despite successful intraoperative revascularization, the patient developed diminished motor and sensory function with unremitting pain, and subsequent electromyography confirmed a length-dependent neuropathy with features of denervation, consistent with IMN. This case underscores the critical need for clinicians to consider IMN in the differential diagnosis of post-procedural neuropathic pain, even in the absence of classic ischemic signs and following seemingly successful vascular interventions, as acute thrombotic events during vascular procedures can precipitate this debilitating condition.

ABSTRACT Determining an appropriate sample size in human cadaveric studies remains a long‐standing and unresolved challenge. Unlike other basic science fields, anatomical research is constrained by factors such as limited human donor availability, cultural considerations, and ethical restrictions. Despite these limitations, researchers are often asked to justify sample sizes, yet no standardized guidelines currently exist. To quantitatively assess sample sizes in recent human cadaveric studies and propose evidence‐based recommendations for future research, a PubMed search was conducted on February 26, 2024, using the term human cadaveric study . The articles published in 2023 and 2024 were screened, yielding 770 eligible studies. Data extracted included the total sample size, number of classified groups, and journal impact factor (IF). Descriptive statistics, linear regression, and correlation analyses were performed. Continuous variables were summarized using medians and interquartile ranges (IQR). The median sample size was 11.5 (IQR: 7–20), and 47.9% of studies used 10 or fewer specimens. The median number of classified groups was 3 (IQR: 2–4). Linear regression showed that studies dividing specimens into 2–6 groups often failed to meet the recommended sample size per group based on regression modeling. No significant correlation was found between sample size and journal IF ( r = −0.062, p = 0.115). Most cadaveric studies rely on small sample sizes due to inherent constraints, yet many still attempt a subgroup analysis without sufficient statistical power. Although flexibility is essential in anatomical research, we recommend a minimum total sample size of 10 for basic studies and at least five samples per group for those involving classification. Cadaveric sample size alone does not predict journal impact, highlighting the importance of methodological rigor over quantity.

Abstract In recent years, there has been increasing interest in the possible prognostic impact of concomitant medications in patients with cancer treated with immunotherapy combinations. This real‐world analysis aims to evaluate the impact of concomitant medications on survival outcomes in patients with advanced biliary tract cancer (BTCs) treated with cisplatin, gemcitabine and durvalumab (CGD) therapy. The study cohort included patients with a diagnosis of advanced BTCs who were taking concomitant medications for their comorbidities before the start of CGD. The primary objectives were overall survival (OS) and progression‐free survival (PFS). The initial population consisted of 666 patients, who were retrospectively collected from 41 sites in 12 countries. Data on concomitant medications were available for 493 patients. After a median follow‐up of 8.8 months (95% CI: 7.8–9.8), patients who did not take steroids (prednisone >10 mg/day or equivalent) or nonsteroidal anti‐inflammatory drugs (NSAIDs) and opioids, before the start of CGD, had longer OS and PFS in univariate analysis. The multivariate analysis confirmed longer OS for patients who did not take steroids. Patients who did not take steroids had an OS of 14.8 months (95% CI: 13.1–29.1) versus 5.0 months (95% CI: 2.14–11.32) of patients who took prednisone >10 mg/day or equivalent. No differences were reported in terms of overall response rate (ORR), disease control rate (DCR) ( p = 1.0 and p = .16, respectively), and safety profile between the two groups. Our analysis suggests that patients who did not receive steroids before the start of GCD had longer survival and highlighted the relevance of balancing concomitant medications and chemoimmunotherapy.

PURPOSE Colorectal cancer (CRC) incidence and mortality have decreased since the 1970s, but the incidence in young adults (<50 years, named early-onset CRC [eoCRC]) has been increasing. PATIENTS AND METHODS Individual patient data on 13,365 patients with metastatic CRC enrolled between 2000 and 2012 in 17 first-line randomized trials in the Aide et Recherche en Cancérologie Digestive database were pooled. The distribution of demographics, clinicopathologic features, biomarkers, and outcome data were summarized and compared by age groups. Progression-free survival (PFS) and overall survival (OS) were assessed by Kaplan-Meier curves and Cox models stratified by treatment arms within studies, adjusting for potential confounders. Predictive value of age group on clinical outcomes was evaluated by testing interaction effect between treatment and age variables. RESULTS Overall, 2,045 patients with eoCRC (median age, 42.5) and 11,320 patients with average-onset CRC (aoCRC; median age, 63.8) were included in this analysis. Within the eoCRC population, treatment with bevacizumab in addition to chemotherapy improved PFS (9.9 v 6.8 months; hazard ratio [HR], 0.66 [95% CI, 0.54 to 0.80]; P < .0001), which was similar to the findings in aoCRC population (9.4 v 7.3 months; HR, 0.73 [95% CI, 0.67 to 0.80]; P < .001; interaction P = .5415). However, epithelial growth factor receptor inhibitor (EGFRi) did not improve PFS in RAS wild-type (WT) patients with eoCRC who had left-sided primary tumors (8.3 v 8.9 months; HR, 1.20 [95% CI, 0.81 to 1.77]; P = .36), whereas EGFRi significantly improved PFS in the aoCRC population (9.9 v 8.5 months; HR, 0.74 [95% CI, 0.64 to 0.86]; P < .0001; interaction P = .083). CONCLUSION Treatment-naïve patients with metastatic eoCRC appear to derive similar benefit from bevacizumab as patients with aoCRC. However, patients with eoCRC with left-sided RAS/RAF WT tumors did not appear to derive benefit from first-line EGFRi.

Introduction: Glucagon-like peptide-1 (GLP-1) receptor agonists (GLP1RAs) are increasingly used to treat obesity and other metabolic conditions; however, they are known to inhibit gastrointestinal motility. Since gastrointestinal microbial overgrowth (MO) can arise in states of intestinal stasis, we sought to investigate the potential association between GLP1RA use and MO. Methods: We analyzed data from 99 patients prescribed GLP1RAs who subsequently underwent testing for MO via intestinal aspirate culture or glucose or lactulose breath tests. Results: Most patients had diabetes. Among patients who underwent culture, 76.2% tested positive for small intestinal bacterial overgrowth (SIBO) at a threshold of ≥10³ CFU/mL, with a significant association found between proton pump inhibitor (PPI) use and SIBO. At ≥10 5 CFU/mL, 33.3% tested positive for SIBO, and neither PPI use nor surgical history was associated. Breath testing revealed a 30.6% positivity rate for MO, predominantly characterized by intestinal methanogen overgrowth (IMO). There was no association between control of diabetes and positive MO tests. Conclusion: GLP1RA use is associated with SIBO, although diabetes may be a confounder.
