Listing and transplanting patients with acute liver failure (ALF) is challenging, requiring rapid assessment of the likelihood of recovery. The availability of a large number of ALF liver explants, along with their clinical data, afforded an opportunity to retrospectively evaluate liver transplantation (LT) decision-making. We hypothesized that, with the benefit of hindsight, a small number of patients might have recovered without LT. Three hundred liver explants from ALF patients of varying etiologies who had undergone LT over 22 years in the Acute Liver Failure Study Group registry were reviewed for histopathological features and degree of necrosis by a committee of 8 hepatopathologists. A second committee of 8 experienced transplant hepatologists independently reviewed clinical data on these same 300 patients and retrospectively scored the likelihood that each patient required transplantation. Only 3 (1%) of those reviewed by the Clinical Committee were considered to “Definitely” not require liver grafting, while an additional 10 (3.3%) were deemed to “Possibly” not require transplantation (Not Likely Group, N=13). There was no difference in the degree of necrosis in explants in these groups, when compared to the remaining Likely Group, N=287 (95.6%), except in acetaminophen (APAP)-associated ALF, where the degree of necrosis was more uniformly graded as severe, correlating with the need for transplantation. Virtually every patient undergoing LT for ALF retrospectively appeared to need their transplant, based on expert clinical consensus review. Overall, there was poor correlation between clinical severity and apparent degree of necrosis seen in the 300 liver explants, except perhaps for APAP subjects.

Abstract Objective Rare large B-cell lymphomas (LBCLs) present with concurrent or subsequent lymphomatous effusion (solid-effusion LBCL, SE-LBCL), which may have an inferior prognosis compared with their noneffusion counterpart. In addition, the relationship between SE-LBCL and human herpesvirus 8–negative effusion-based LBCL (EB-LBCL) remains unclear. Methods We collected 141 cases of SE-LBCL and a control cohort of 101 cases of stage IV solid-only LBCL. The clinicopathologic features were analyzed and compared between SE-LBCL and solid-only LBCL. Results Patients with SE-LBCL had a median age of 67 years with a male-to-female ratio of 1.3:1. Eighty-six patients had concurrent solid lymphoma and lymphomatous effusion, whereas 55 developed lymphomatous effusion subsequently. Most cases involved the pleural cavities (79%, 112/141), followed by the peritoneal (21%, 29/141) and pericardial (11%, 16/141) cavities. BCL6, CD10, and MUM1 were expressed in 77% (90/117), 46% (60/130), and 61% (58/95) of cases, respectively, and 58% (71/123) were subclassified into the germinal center B-cell (GCB) subtype. Rearrangements of BCL2, BCL6, and MYC were detected in 42% (31/73), 35% (22/63), and 40% (35/88), respectively, and 22% (19/87) had both MYC and BCL2 rearrangements. The patients with SE-LBCL had a dismal prognosis, with a median survival of 5.7 months, which was significantly worse than solid-only LBCL (147.5 months; P < .0001). Conclusions The pathologic features of SE-LBCL were similar to those of solid-only LBCL but distinct from those of EB-LBCL; in particular, lymphomatous effusion was an independently adverse prognostic factor in LBCL. Our study underscores the need for surveillance of lymphomatous effusion during LBCL staging and development of effective therapeutic regimens for SE-LBCL.

Background Secondary aortoenteric fistulas (SAEF) following endovascular aortic repair (EVAR) is an extremely rare event but life threatening. Our review offers comprehensive knowledge on pathophysiology, clinical presentation, diagnosis, and treatment options. Aim To summarize the current literature regarding pathophysiology, clinical, diagnostic and therapeutic approach of aortoenteric fistulas secondary to EVAR. Methods We performed a literature search in Pubmed/MEDLINE to identify the literature published about SAEF after EVAR. Cases were summarized in a table and prevalences. Other relevant literature was included in the results sections. Results A total of 35 reports (single cases and small series) with 45 patients were included. SAEF after EVAR can result from infection, inflammation, or mechanical factors. Clinical presentation is often non-specific, ranging from a gastrointestinal herald bleed to hemorrhagic shock, or malaise and general infection-related symptoms. Cross-sectional imaging plays a critical role in diagnosing SAEF. The treatment approach involves a multidisciplinary team approach and requires broad-spectrum intravenous antibiotics, endovascular intervention for urgent hemorrhage control, and open surgical intervention for definitive repair. Long-term antimicrobial therapy is essential to avoid reinfection. Conclusions SAEF following EVAR represents a complex, life-threatening condition with limited evidence-based management strategies. Given the growing prevalence of endovascular procedures, comprehensive knowledge of SAEF is crucial for all health care providers to improve early diagnosis and outcomes.

Abstract Objective Glucocorticoid withdrawal syndrome (GWS) may develop in patients following successful surgery for endogenous hypercortisolism. Effective strategies to minimize GWS and improve quality of life (QoL) are currently lacking. We aimed to determine the impact of hydrocortisone vs prednisone therapy on GWS and QoL during the first 12 weeks postsurgery. Methods Single-center prospective cohort study (2019-2024) of adults with endogenous hypercortisolism who developed postoperative adrenal insufficiency and treated with either prednisone or hydrocortisone. Quality of life was assessed with Short Form-36 (SF-36) and Cushing QoL questionnaires at baseline and at 12 weeks postsurgery. GWS was assessed using weekly AddiQoL questionnaires for the first 12 weeks postsurgery. Results Of 165 patients, 101 (61%) were treated with hydrocortisone and 64 (39%) with prednisone. At baseline, no group differences were found in the hypercortisolism subtype, comorbidities, or QoL assessments. At follow-up, no group differences in final total daily hydrocortisone equivalent dose were seen. When adjusting for the baseline QoL assessment, patients treated with prednisone demonstrated a higher degree of improvement in their QoL, particularly in the SF-36 mental component score (estimate 0.33, 95% CI, 0.04-0.63), SF-36 role-emotional limitation (estimate 0.52, 95% CI, 0.2-0.84), and SF-36 body pain (estimate 0.31, 95% CI, 0.07-0.56) subcomponents. In the multivariable analysis of age, sex, body mass index, glucocorticoid type, baseline clinical severity score, and baseline QoL assessment, prednisone therapy was an independent predictor of better SF-36 mental component at 12 weeks postsurgery. Conclusions Prednisone therapy was associated with better mental health QoL than hydrocortisone at 12 weeks postsurgery in patients with hypercortisolism.

AbstractAlthough guidelines have historically recommended deferring decisions about learning genomic information for conditions not actionable in childhood until adulthood, youth have increasing access to personal genomic information through research, clinical, and direct‐to‐consumer testing. However, little is known about young people's reactions to, and perceived future utility of learning genomic information actionable in adulthood. We conducted qualitative interviews with 28 youth ages 15–22 without clinical indications for genetic screening who, through enrollment in a genomic decision‐making research study, learned they were carriers of an autosomal recessive condition, or anticipated being carriers but received negative results. Semi‐structured interviews occurred virtually between 3 and 16 months after the return of results. Interpretative description guided deductive and inductive coding of transcripts. Of the 28 participants, 21 received positive carrier results, and 7 received negative results. Although some carriers felt the result was unexpected, they expressed relief overall and did not feel worried about their result. Participants with negative results also felt relief about their results. All participants correctly described what a carrier result means, but some carriers could not remember the condition associated with their result. No participant regretted learning personal genomic information, and all reported their results helped them better understand risks to future children. Carriers who perceived the condition for which they were carriers as more severe and/or those familiar with the condition were more likely to remember their result and consider future reproductive options. Carriers also felt testing at their respective age allowed increased familiarity with results and more time to gather information and decide on the personal utility of the information. Our findings suggest early access to genomic information for some youth may allow integration of carrier information over time with minimal adverse effects. More research is needed to assess long‐term outcomes among carriers.

PURPOSE Sertoli-Leydig cell tumors (SLCTs) are rare sex cord-stromal tumors, representing <0.5% of all ovarian tumors. We analyze the role of germline DICER1 status in outcomes of ovarian SLCT. METHODS Patients with SLCT were enrolled in the International Pleuropulmonary Blastoma/ DICER1 Registry and/or the International Ovarian and Testicular Stromal Tumor Registry. Medical records were systematically abstracted, and those with known germline DICER1 status were selected for analysis. RESULTS Of 162 patients with SLCT, 60% had a germline DICER1 pathogenic or likely pathogenic (P/LP) variant. The adjusted 3-year recurrence-free survival (RFS) was 87.2% (95% CI, 79.4 to 95.8) for patients with a germline DICER1 P/LP variant compared with 78.1% (95% CI, 66.4 to 91.9) for those without a germline DICER1 P/LP variant ( P = .043). The adjusted 3-year and 5-year overall survival (OS) was 93.9% (95% CI, 87.3 to 100.0) for those with a germline DICER1 P/LP variant compared with the 3-year OS of 91.3% (95% CI, 83.4 to 100.0) and the 5-year OS of 78.2% (95% CI, 63.8 to 95.9) for those without a germline DICER1 P/LP variant ( P = .021). Among patients with a germline DICER1 P/LP variant, the risk of a subsequent, nonrecurrent event was 36.2% (95% CI, 21.4 to 48.1) within 10 years. Previous/concurrent and subsequent neoplasms were rare among those without a germline DICER1 P/LP variant. CONCLUSION This cohort study of patients with SLCT demonstrated that those with germline DICER1 P/LP variants had superior RFS and OS even when adjusting for other prognostic factors. Beyond prognostic implications of a germline DICER1 P/LP variant, germline testing helps identify patients at risk of subsequent neoplasms, including metachronous SLCT.

AbstractBackgroundOvarian juvenile granulosa cell tumors (juvGCT) are rare sex cord‐stromal tumors that occur primarily in children and adolescents. This study summarizes the clinical presentation and outcomes of patients with juvGCT.MethodsPatients were enrolled in the International Ovarian and Testicular Stromal Tumor and/or International Pleuropulmonary Blastoma/DICER1 Registries. Available medical records were abstracted, and pathology was centrally reviewed. Surgical staging was classified using the 2014 International Federation of Gynecology and Obstetrics (FIGO) criteria.ResultsIn total, 70 patients with juvGCT enrolled and were diagnosed between 2001 and 2024; most patients (81%, 57 of 70) presented with FIGO stage I disease. Adjuvant chemotherapy was given in 30% (21 of 70); all regimens were platinum‐based. Three‐year event‐free survival among patients with stage IA tumors was 80.2% (95% confidence interval [CI], 62.4%–100.0%), IC1 was 87.4 (95% CI, 72.4%–100.0%), IC2‐IC3 was 63.6% (95% CI, 40.7%–99.5%), and II‐IV was 48% (95% CI, 24.6%–93.8%). Of the patients with recurrent juvGCT with known mitotic index (MI), all had MI greater than 19 mitoses per 10 high power fields (HPF) at diagnosis.ConclusionOutcomes were worse for patients with FIGO stage ≥IC2 disease and for tumors with >19 mitoses per 10 HPF. Given the prognostic significance of MI, the authors strongly recommend the assessment of MI for all juvGCTs. More information about tumor biology is critical to identify which patients may benefit from adjuvant chemotherapy and to facilitate the development of novel therapies.

PURPOSE Chemotherapy-induced peripheral neuropathy is a potentially debilitating adverse effect of cancer therapy that can lead to delay, reduction, or discontinuation of cancer treatment. Population-based data on peripheral neuropathy incidence among young cancer survivors are lacking. METHODS Using a linkage between Medicaid, the California Cancer Registry, and hospitalization and emergency department data, we identified 6,028 adolescents and young adults (15-39 years) with Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), breast cancer, colorectal cancer, or testicular cancer and 418 children (<15 years) with HL or NHL during 2005-2017. We determined the cumulative incidence of peripheral neuropathy and its association with neurotoxic chemotherapy identified from Medicaid claims, using multivariable Cox proportional hazards regression models. RESULTS Of 6,446 patients, 1,007 were diagnosed with peripheral neuropathy. Across each cancer type, incidence was higher among patients receiving neurotoxic drugs. For example, compared with non-neurotoxic agents, 5-year cumulative incidence was higher with oxaliplatin for colorectal cancer (24.0% v 6.2%) and paclitaxel for breast cancer (22.6% v 5.1%). In multivariable analysis, the agents most strongly associated with peripheral neuropathy were brentuximab (±other neurotoxic drugs) for HL (hazard ratio [HR], 9.53 [95% CI, 5.95 to 15.26]); brentuximab (±vinca alkaloids; HR, 7.00 [95% CI, 4.13 to 11.87]) for NHL, paclitaxel for breast cancer (HR, 4.03 [95% CI, 3.05 to 5.31]); oxaliplatin for colorectal cancer (HR, 3.46 [95% CI, 2.23 to 5.36]); and cisplatin and etoposide for testicular cancer (HR, 2.06 [95% CI, 1.37 to 3.11]). CONCLUSION The high incidence of peripheral neuropathy highlights the need for frequent monitoring, new supportive care approaches, and development of novel therapeutic agents to minimize toxicity while maintaining treatment efficacy.

Abstract Introduction: Most people who die from prostate cancer are older than 75 years. However, prostate cancer diagnosed at younger ages is often more aggressive. While epidemiologic studies have examined the association between age and survival in patients with prostate cancer overall, the clinical drivers of this relationship in patients with advanced disease remain unclear. We leveraged the International Registry of Men with Advanced Prostate Cancer (IRONMAN, NCT03151629) to (1) quantify the association between age and overall survival and (2) explore whether this association is explained by treatments. Methods: We included 3, 734 patients enrolled from 15 countries with new diagnoses of metastatic hormone sensitive (mHSPC, N=2, 642) or castration resistant prostate cancer (CRPC, N=1, 092). Age at enrollment was categorized as &lt;55, 55-59, 60-64 (reference), 65-69, 70-74, 75-79, 80-84, 85+ years. We computed age-specific death rates (95% confidence intervals [CIs]) by disease state (mHSPC, CRPC) at enrollment. To explore whether this relationship was explained by treatment, we fitted disease state-stratified Cox models and sequentially adjusted for (1) de novo metastatic status and country, and (2) baseline treatment (androgen deprivation therapy [ADT] alone, ADT + androgen receptor pathway inhibitors [ARPI], ADT + chemotherapy, ADT + ARPI + chemotherapy, other). Results: Over 5.5 years of follow-up (median: 3.2 years, IQR: 1.7, 4.8), 995 patients died from any cause. Younger patients were more likely to have de novo metastatic disease. Among those with mHSPC at enrollment, the age-specific death rates per 1, 000 person-years followed a J-shaped pattern: 80 (95% CI: 54, 117) in patients under 55 years, 58 (46, 74) in patients aged 60-64, 102 (78, 133) in patients aged 80-84, and 172 (125, 236) in patients aged 85 and older. The death rates among those with CRPC followed a similar pattern, albeit rates were higher in magnitude: 212 (95% CI: 140, 323) in patients under 55 years, 153 (115, 202) in patients aged 60-64, 200 (155, 258) in patients aged 80-84, and 204 (142, 291) in patients aged 85 and older. After adjusting for disease state, country, and the timing of diagnosis of metastases, death rates were substantially higher for ages 75-79 (HR 1.4; 95% CI 1.1, 1.7), 80-84 years (HR 1.6; 95% CI 1.2, 2.1), and 85 years and older (HR 2.0; 95% CI: 1.5, 2.7) compared to ages 60-64 years. Patients aged under 55 years had 1.4-fold higher death rates (95% CI: 1.0, 1.9) compared to those 60-64 years. After additionally adjusting for baseline treatment, overall survival remained worse for the older patients and the youngest age group with hazard ratios remaining meaningfully unchanged. Conclusion: Age at enrollment is associated with overall survival in people with advanced prostate cancer enrolled in IRONMAN in a J-shaped pattern. This relationship is not explained by differences in baseline treatment. Citation Format: Hannah E. Guard, Michelle O. Sodipo, Colleen B. McGrath, Anna Siefkas, Lauren E. Howard, Konrad H.
