OBJECTIVES: Explore short-term effects of “The Caregiver Pathway,” an intervention for family caregiver follow-up, on Post-Intensive Care Syndrome symptoms among families (PICS-F). DESIGN: A randomized controlled trial. SETTING: A medical ICU at a Norwegian University Hospital. PARTICIPANTS: One hundred ninety-six family caregivers of critically ill patients randomized to an intervention (n = 101) or control group (n = 95). INTERVENTIONS: “The Caregiver Pathway” four-step model offers individual and structured follow-up, including: 1) mapping family caregivers’ needs and concerns with an assessment tool followed by a conversation with an ICU nurse within the first days at the ICU, 2) a supportive card when leaving the ICU, 3) offer for the family caregivers to receive a phone call after ICU patient discharge, and 4) a follow-up conversation within 3 months. MEASUREMENTS AND MAIN RESULTS: Data were collected at baseline and after 3 months and analyzed using linear regression. No significant effects were detected when comparing all participants completing 3-month outcome measurements (n = 144). A subgroups analysis stratified on patient survival, however, showed statistically significant effect for family caregivers of patients surviving the ICU stay receiving the intervention compared with controls. Caregivers of surviving patients reported improved symptoms related to post-traumatic stress disorder, measured by Impact of Event Scale-Revised (B = –8.2 [95% CI, –14.2 to –2.2]; p = 0.008), anxiety (B = –2.2 [95% CI, –4.0 to –0.5]; p = 0.014), and depression (B = –1.5 [95% CI, –2.9 to –0.1]; p = 0.035); measured by the Hospital Anxiety and Depression Scale, subscore physical functioning in health-related quality of life (B = 9.7 [95% CI, 0.3–19.0]; p = 0.043); measured by Short Form 12-Item Health Survey; and hope (B = 2.4 [95% CI, 0.4–4.3]; p = 0.017) and measured by the Herth Hope Index. At 3-month, the model did not appear to improve the outcomes for family caregivers of nonsurviving patients. CONCLUSIONS: “The Caregiver Pathway” intervention was associated with reduced symptoms of PICS-F in family caregivers of surviving ICU patients compared with controls.

ASCO Guidelines provide recommendations with comprehensive review and analyses of the relevant literature for each recommendation, following the guideline development process as outlined in the ASCO Guidelines Methodology Manual . ASCO Guidelines follow the ASCO Conflict of Interest Policy for Clinical Practice Guidelines . Clinical Practice Guidelines and other guidance (“Guidance”) provided by ASCO is not a comprehensive or definitive guide to treatment options. It is intended for voluntary use by clinicians and should be used in conjunction with independent professional judgement. Guidance may not be applicable to all patients, interventions, diseases or stages of diseases. Guidance is based on review and analysis of relevant literature and is not intended as a statement of the standard-of-care. ASCO does not endorse third-party drugs, devices, services, or therapies and assumes no responsibility for any harm arising from or related to the use of this information. See complete disclaimer in Appendix 1 and 2 (online only). PURPOSE To provide evidence-based guidance for clinicians who treat patients with stage I-III anal cancer. METHODS A systematic review of the literature conducted by the Minnesota Evidence-based Practice Center provided the evidence base for this guideline. An ASCO Expert Panel reviewed this evidence and came to consensus on a set of evidence-based recommendations. RESULTS The systematic review contained three randomized controlled trials and three nonrandomized studies of interventions that were relevant to the guideline topic and informed the recommendations. RECOMMENDATIONS Mitomycin-C (MMC) with a fluoropyrimidine (fluorouracil [FU] or capecitabine) is recommended as the radiosensitizing component of chemoradiation (CRT) for anal cancer; the Expert Panel recognizes that capecitabine is often used as an orally administered alternative to FU and is currently being used in ongoing clinical trials. Cisplatin with FU is an additional chemotherapy combination that may be recommended as radiosensitizing chemotherapy. Because of the myelosuppression associated with MMC, the preferable regimen for patients with immunosuppression is cisplatin and FU. Cisplatin is not recommended for patients with renal dysfunction, significant neuropathy, or hearing loss, and there is no evidence to recommend substituting carboplatin for cisplatin. Dose and schedule options for recommended chemotherapy agents are included within the full text of the guideline. Routine induction chemotherapy before CRT and additional chemotherapy after CRT are not recommended for patients with localized anal cancer.

Background: Isatuximab is an IgG1κ monoclonal antibody that binds with high affinity to CD38 expressed on plasma cells in light chain (AL) amyloidosis. Anti-CD38 antibodies have shown efficacy alone and in combination in a variety of settings for patients with multiple myeloma and light chain (AL) amyloidosis. Here we report the final analysis of a multi-center, cooperative group prospective phase II study of isatuximab in previously treated patients with AL amyloidosis (NCT03499808). Methods: Eligibility included: age ≥18 years, relapsed or refractory systemic AL amyloidosis, ≥1 prior line of therapy, measurable disease, ≥1 organ involved, not refractory to daratumumab, Eastern Cooperative Oncology Group performance status ≤2, creatinine clearance ≥25 mL/min, and NT-proBNP ≤8500 pg/mL. Patients received isatuximab intravenously 20 mg/kg weekly during the first 28-day cycle and every other week during cycles 2 through 24 for a maximum of 24 cycles. The primary objective was hematologic response with secondary objectives of organ response, safety, progression free survival, and overall survival. Results: Forty-three patients were registered, with 35 patients being eligible for response. The median age of the evaluable patients was 70 years (range, 40.1-79.5) with the majority (66%, n=23) having a lambda clonal plasma cell dyscrasia. The most common cytogenetic abnormality using fluorescence in situ hybridization was translocation t(11;14) observed in ten patients (29%). The most common prior treatment was a proteasome inhibitor (94%, n=33) while 46% (n=16) had undergone autologous stem cell transplant. Eighteen patients (51%) had single organ involvement while 17 (49%) had multiple organs involved. The distribution of organ involvement was typical for AL amyloidosis with cardiac involvement in 25 patients (71%) and renal involvement in 14 (40%). As of December 30, 2022, no new safety concerns were identified. The most common treatment related grade ≥3 adverse events included lymphopenia (n=3, 8.5%) and infection (n=2, 6%). The overall hematologic response rate was 77.1% with a rapid median time to partial response or better of 1.1 months. Two patients (6%) achieved a hematological complete response (CR), 18 (51%) had a very good partial response (VGPR), and 7 (20%) had a partial response (PR). At 24 months from hematologic response, the rate of patients still in response was estimated at 81% (95% confidence interval (CI): 67, 96). The 24-month estimated overall survival was 85% (95% CI: 73%, 97%). Renal response occurred in 50% (7/14) of patients with renal involvement with a median time to response of 18.5 months. Cardiac response occurred in 56% (14/25) of patients with cardiac involvement with a median time to response of 16.6 months. Conclusions: Isatuximab monotherapy resulted in high rates of hematologic response in relapsed AL amyloidosis which translated into organ responses. Treatment appears safe and was well tolerated.

Background and significance: Light chain (AL) amyloidosis is a plasma cell malignancy characterized by the production of amyloidgenic clonal light chains that deposit in various tissues. The addition of daratumumab to bortezomib, cyclophosphamide and dexamethasone (Dara-VCD) has improved the depth of hematologic and organ responses and is an approved induction therapy in newly diagnosed AL amyloid patients (DOI: 10.1056/NEJMoa2028631). However, this approach has not yet demonstrated an overall survival (OS) benefit and follow up remains short. With strict adherence to eligibility criteria, in particular severity of cardiac involvement, autologous stem cell transplantation (ASCT) as consolidative therapy is safe with transplant related mortality on par with multiple myeloma. This approach generates deep and sustained responses, but it is unclear if it offers an additional survival benefit following Dara-VCD induction. The only randomized trial evaluating the role of ASCT in AL amyloid is outdated (DOI: 10.1056/NEJMoa070484) and no randomized data exist to inform the optimal use of ASCT in the era of Dara-VCD induction. Furthermore, multi-organ involvement in AL amyloid drives morbidity and mortality thus the impact of any consolidative therapy on cardiac and renal involvement in addition to overall survival but must be defined. Finally, the approval of Dara-VCD therapy was based on complete hematologic response rates but there is increasing data demonstrating that achieving minimal residual disease (MRD) negativity by either bone marrow next generation flow cytometry (DOI: 10.1002/ajh.26562) or peripheral blood mass spectrometry (DOI: 10.1038/s41408-020-0291-8) generates improved organ response, hematologic progression free survival, and possibly OS. Methods: This randomized phase 3 SWOG led intergroup trial (S2213; NCT06022939) is being conducted within the United States and will accrue a total of 143 participants per arm. The primary endpoint will compare MOD-PFS (major organ deterioration progression free survival: defined as time from randomization to death, cardiac/renal progression, or hematologic progression) between participants receiving an ASCT with those receiving 3 cycles of Dara-VCD consolidation following 3 cycles of uniform Dara-VCD induction. Following the assigned consolidation, all patients will receive 18 months of daratumumab maintenance therapy. A median MOD-PFS of 31 months is anticipated in the non-ASCT arm. This study has 90% power and a two-sided significance level of 0.05 to detect a hazard ratio of 0.62 corresponding to a MOD-PFS of 50 months in the ASCT arm. Important additional endpoints include OS, hematologic PFS, cardiac and renal responses, MRD negativity both by peripheral blood mass spectrometry and bone marrow next generation flow cytometry, delayed utilization of ASCT, and quality of life. Key inclusion criteria include non-severe cardiac AL amyloid (NT-proBNP <5000; TnT < 0.06; NYHA I or II, EF ≥ 40%), CrCl ≥30 mL/min, serum dFLC > 2 mg/dL, and supine systolic BP ≥ 90 mmHg. Importantly, patients are permitted to have up to one full cycle or 28 days of any plasma cell directed therapy prior to enrollment. This trial was activated on 12/1/2023 with the first patient enrolled 07/01/2024.

Background: Although no tests are currently available to predict post-stroke depression (PSD), a risk factor for diminished quality of life and stroke-related death, emerging evidence suggests that ischemic stroke (IS) may induce behavioral changes by damaging connections throughout the brain rather than via localized injury. Hypothesis: We sought to determine if active (surveys) and passive (accelerometer, GPS, and other sensors) smartphone data could quantify exploratory behavioral proxies of PSD. Methods: Thirty-four adults with a recent IS (n = 12) or transient ischemic attack (TIA) (n = 22) diagnosis were followed for 3 months. Participants used the Beiwe app to complete a weekly Patient Health Questionnaire-8 (PHQ-8) survey and were evaluated every 30 days with the Montgomery-Asberg Depression Rating Scale (MADRS). Results: Preliminary analysis of app survey compliance was adequate (86%), and the quantity of data collected was greater for Android than iOS phones. PHQ-8 indicated depression (moderate or severe) in 20% of participants. MADRS highly correlated with the most recent PHQ-8 ( r = 0.92, 95% CI (0.19, 0.99), P = 0.028). Several exploratory passive physical activity and social measures showed statistically significant change over time and/or associations with PHQ-8 and MADRS. Conclusion: Low-burden smartphone data holds promise for developing novel IS and TIA outcome measures as well as identifying patients most at risk of PSD.

Cardiac ventricular pressure overload affects patients with congenital heart defects and can cause cardiac insufficiency. Grafts of stem cell–derived cardiomyocytes are proposed as a complementary treatment to surgical repair of the cardiac defect, aiming to support ventricular function. Here, we report successful engraftment of human induced pluripotent stem cell–derived cardiac lineage cells into the heart of immunosuppressed rhesus macaques with a novel surgical model of right ventricular pressure overload. The human troponin+ grafts were detected in low-dose (2 × 10 6 cells/kg) and high-dose (10 × 10 6 cells/kg) treatment groups up to 12 weeks post-injection. Transplanted cells integrated and progressively matched the organization of the surrounding host myocardium. Ventricular tachycardia occurred in five out of 16 animals receiving cells, with episodes of incessant tachycardia observed in two animals; ventricular tachycardia events resolved within 19 days. Our results demonstrate that grafted cardiomyocytes mature and integrate into the myocardium of nonhuman primates modeling right ventricular pressure overload.

ABSTRACT Hepatic angiosarcoma is a rare and aggressive liver tumor. We report a case study of an 82-year-old elderly gentleman who presented with failure to thrive and ascites. Initially suspected to be cirrhosis, biopsy results eventually concluded angiosarcoma of the liver. Our patient presented with an infiltrative form, rather than distinct masses, which led to portal hypertension and ascites. The variance in symptomatology and radiology presentations make a diagnosis of hepatic angiosarcoma challenging and require a high index of suspicion.

Abstract Introduction: Chronic pain affects a wide range of physical and psychological aspects of life for those impacted. Psychosocial treatment approaches may be of support, but outreach is still limited. Objectives: To evaluate the efficacy of EPIO, an evidence-informed, user-centered digital self-management intervention for people with chronic pain, in a 12-month randomized controlled trial. Methods: People living with chronic pain (N = 266) were randomized to the EPIO intervention (n = 132) or a usual-care control group (n = 134). The intervention was delivered in a simple blended care model, and outcome measures collected at baseline, 6 months, and 12 months. Generalized linear models for repeated measures were fitted to compare groups over time. Results: Participants were primarily female (81%), median age 49 years (range 22–78), with heterogeneous pain conditions, and had lived with pain >5 years (77.6%). A mixed linear model with all timepoints included revealed no statistically significant group differences for the primary outcome of pain interference. Significant psychological benefits in favor of the intervention group were however detected for depression (P = 0.022), self-regulatory fatigue (P = 0.024), vitality (P = 0.016), and mental health (P = 0.047). Baseline to 12-month changes showed additional favorable effects for anxiety (between-group mean differences [MDs] = 0.79, P = 0.047), depression (MD = 1.08, P = 0.004), self-regulatory fatigue (MD = 2.42, P = 0.021), pain catastrophizing (MD = 2.62, P = 0.009), and health-related quality of life. Conclusions: The EPIO program aims to improve outreach of evidence-based pain self-management interventions. Findings demonstrate how using EPIO can lead to sustainable psychological change, enhancing mental health and health-related quality of life for people suffering from pain, providing a chance to live well with the pain.

Abstract Aberrant activation of GLI transcription factors has been implicated in the pathogenesis of different tumor types including pancreatic ductal adenocarcinoma. However, the mechanistic link with established drivers of this disease remains in part elusive. In this study, using a new genetically engineered mouse model overexpressing constitutively active mouse form of GLI2 and a combination of genome-wide assays, we provide evidence of a novel mechanism underlying the interplay between KRAS, a major driver of pancreatic ductal adenocarcinoma development, and GLI2 to control oncogenic gene expression. These mice, also expressing KrasG12D, show significantly reduced median survival rate and accelerated tumorigenesis compared with the KrasG12D only expressing mice. Analysis of the mechanism using RNA sequencing demonstrate higher levels of GLI2 targets, particularly tumor growth–promoting genes, including Ccnd1, N-Myc, and Bcl2, in KrasG12D mutant cells. Furthermore, chromatin immunoprecipitation sequencing studies showed that in these cells KrasG12D increases the levels of trimethylation of lysine 4 of the histone 3 (H3K4me3) at the promoter of GLI2 targets without affecting significantly the levels of other major active chromatin marks. Importantly, Gli2 knockdown reduces H3K4me3 enrichment and gene expression induced by mutant Kras. In summary, we demonstrate that Gli2 plays a significant role in pancreatic carcinogenesis by acting as a downstream effector of KrasG12D to control gene expression.
