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.

In 2023, the VAS international working group on Buerger’s Disease (BD) recommended two diagnostic criteria based on a prior Delphi study: “definitive” and “suspected”. The “definitive” criteria are history of smoking, typical angiography, and typical histopathological features. All three features are mandatory to confirm a “definitive” diagnosis of BD. The conundrum is—what features should be considered typical of BD angiography? According to this review, segmental occlusion of infrapopliteal arteries, corkscrew collaterals that appear to continue the occluded arterial segment (Martorell’s sign) or bypass the segmental occlusion, absence of atherosclerotic plaque or aneurysm could differentiate BD from ASO. Hence, for “typical” BD angiography, these manifestations should certainly be considered. However, data for differentiating angiography patterns of BD from the small- and medium-sized vasculitis including Behcet’s disease, scleroderma, hepatitis associated vasculitis, and anti-phospholipid syndrome are limited. Further studies for investigating the angiography pattern in BD patients in early and late presentation of BD, particularly in the patients with long-term follow up, are highly recommended.

Abstract Background Although the choice of dialysis technique is based on several factors, patient survival is undoubtedly one of the most relevant. In a context where randomization to either peritoneal dialysis (PD) or hemodialysis (HD) proved to be extremely challenging, previous meta-analyses were greatly limited due to the inclusion of historical studies. Methods We performed a systematic review by searching multiple databases up to April 22nd, 2022. The primary outcome was the association between dialysis modality (PD vs HD) and mortality assessed via hazard ratios (HR). Subgroup analyses were conducted to explore potential sources of heterogeneity, including sex, age, diabetes, dialysis vintage, geographical location, HD access, and study cohort inclusion period. Results Database search yielded 5317 citations, from which, 27 observational studies met the eligibility criteria, including 1 033 362 incident dialysis patients. The pooled mortality HR for PD versus HD was 1.01 (95% CI 0.93–1.10). Heterogeneity was substantial ( I 2 = 94%) and was largely explained by different baseline features of the included populations. A statistically significant subgroup effect was demonstrated for age (> 65 vs.<65 years; p = 0.01), geographical location of the studies (Oceania vs. Europe vs. Asia vs. North America; p < 0.01), and HD vascular access (central venous catheter vs. arteriovenous fistula; p < 0.01, only one study included). Conclusions This meta-analysis suggests that overall PD and incentre HD likely carry equivalent survival benefits. However, differences were detected among subgroups based on age, geographic location, HD access type, but not on sex, diabetes status, dialysis vintage and study cohort inclusion period.

Abstract Checkpoint inhibitors (CPIs) have shown remarkable efficacy in Hodgkin lymphoma (HL), and are now used routinely. While allogeneic hematopoietic cell transplantation (allo-HCT) remains a curative option for HL, there are concerns prior CPIs may exacerbate post–allo-HCT complications, particularly graft-versus-host disease (GVHD), and lead to worse outcomes. Given the relative paucity of data, we performed a Center for International Blood and Marrow Transplant Research/European Society for Blood and Marrow Transplantation study to examine the impact of prior CPIs in allo-HCT. We included 2186 adult patients aged &gt;18 years who received a first allo-HCT using a matched related, unrelated, or haploidentical donor from 2008 to 2023. Twenty-seven percent of patients received prior CPIs. GVHD prophylaxis was posttransplant cyclophosphamide (PTCy) in 55.8% of patients in the CPI cohort, and 35% in the non-CPI cohort. Median follow-up among survivors was longer for the non-CPI (39 months) than CPI cohort (16.5 months). In multivariate analysis, prior CPI exposure did not affect overall survival (OS) or nonrelapse mortality, but resulted in improved progression-free survival (non-CPI vs CPI hazard ratio [HR], 0.81; 0.67-0.98; P = .03) and lower relapse incidence (HR, 0.58; 0.45-0.76; P &lt; 001). While grade 2 to 4 (HR, 1.26; 1.04-1.53; P = .02) and 3 to 4 (HR, 1.41; 1.04-1.92; P = .03) acute GVHD (aGVHD) were increased, differences in chronic GVHD (cGVHD) were not significant. PTCy–based GVHD prophylaxis resulted in improved OS, lower grade 2 to 4 aGVHD, and cGVHD in patients with prior CPI exposure. In summary, allo-HCT should still be considered a curative option for patients with HL in the era of CPIs.

Abstract Background Cisplatin, gemcitabine, and durvalumab combination is a standard first-line treatment for advanced biliary tract cancer. This study aimed to assess the impact of genetic alterations on outcomes in patients with advanced biliary tract cancer treated with cisplatin, gemcitabine, and durvalumab in real-world clinical practice. Methods Patients with unresectable, locally advanced, or metastatic biliary tract cancer treated with cisplatin and gemcitabine plus durvalumab across 39 centers in 11 countries in Europe, the United States, and Asia were included in this analysis. Results The cohort included 513 patients with advanced biliary tract cancer. The 5 most frequently altered genes were TP53 (22.1%), KRAS (13.7%), CDKN2A/B (13.6%), ARID1A (12.2%), and IDH1 (9.2%). In multivariate analysis, SMAD4 mutations were associated with improved progression-free survival (PFS) (hazard ratio [HR] = 0.49, P = .018) and overall survival (HR = 0.11, P = .023), while TP53 mutations were linked to worse PFS (HR = 1.62, P = .0047) and TERT mutations to worse overall survival (HR = 8.92, P = .0012). No other genomic alterations were statistically associated with outcomes. Subgroup analysis showed that TP53 mutations negatively affected PFS and overall survival in intrahepatic cholangiocarcinoma, while KRAS mutations were associated with poorer PFS in extrahepatic cholangiocarcinoma. No gene alterations were linked to outcomes in gallbladder cancer. Conclusions This large-scale analysis, with comprehensive molecular profiling, supports the positive prognostic impact of SMAD4 mutations for PFS and overall survival and highlights the negative prognostic roles of TP53 (PFS) and TERT (overall survival) mutations, providing valuable insights for personalized treatment strategies in biliary tract cancer.

ABSTRACTAlthough current treatment strategies for nonmalignant airway stenosis may offer short‐term relief, their effectiveness is limited by high recurrence rates, often requiring additional procedures. While paclitaxel‐coated balloons (PCB) have demonstrated effectiveness in treating stenosis across various vascular and nonvascular conditions, their evidence in recurrent airway stenosis remains limited. Here, we present the case of a 35‐year‐old female with bronchial stenosis who underwent multiple bronchoscopic interventions, all of which were complicated by restenosis. Following the addition of a PCB to the therapeutic regimen, the patient achieved sustained airway patency.
