Formononetin May Protect Against Anthracycline Cardiotoxicity Through Cardiac Metabolic Improvement
A preclinical study identified ERRa as an early metabolic regulator of anthracycline-induced cardiotoxicity, with its reduction occurring before overt cardiac dysfunction. Formononetin, an ERRa activator, improved cardiac metabolism and function in mouse and pig models while also enhancing doxorubicin's anticancer activity in breast cancer organoids. The findings suggest a potential dual-action strategy for protecting the heart during anthracycline therapy, but clinical studies are still needed.
KEY FINDINGS: The findings identify ERRα downregulation as an early and potentially causal component of anthracycline-induced cardiac injury. Formononetin improved cardiac energy metabolism and function in experimental models while retaining, and potentially enhancing, doxorubicin's anticancer activity in breast cancer organoids. The study therefore suggests that pharmacologic activation of ERRα could represent a future strategy for simultaneously addressing anthracycline cardiotoxicity and cancer treatment. However, the evidence remains preclinical, and clinical studies are required to determine whether these findings translate into cardioprotection in patients receiving anthracycline chemotherapy.
BACKGROUND: Anthracyclines such as doxorubicin are effective anticancer agents, but their use can be limited by anthracycline-induced cardiotoxicity (AIC). Early metabolic disturbances in cardiac muscle may contribute to the development of cardiac dysfunction. This study investigated the role of estrogen-related receptor α (ERRα), a regulator of cardiac energy metabolism, in AIC and evaluated whether pharmacologic activation of ERRα with formononetin could provide cardiac protection while maintaining anticancer activity.
DETAILS: The investigators used a porcine model of anthracycline cardiotoxicity to examine changes in ERRα over time and cardiomyocyte-specific gain- and loss-of-function mouse models to assess its functional role. Mechanistic experiments, including ChIP-qPCR, reporter assays, and microscale thermophoresis, were used to investigate how formononetin interacts with the ERRα pathway. Cardiac tissue from patients who had received chemotherapy was also examined, while human breast cancer patient-derived organoids were used to evaluate potential effects on tumor activity. ERRα expression was reduced in hearts from the porcine AIC model and in cardiac tissue from patients treated with chemotherapy. In pigs, the reduction occurred at the 6-week subclinical stage, before overt cardiac dysfunction developed. Increasing ERRα expression specifically in cardiomyocytes enhanced mitochondrial metabolic programs and fatty-acid oxidation and preserved systolic function after doxorubicin exposure, whereas ERRα reduction worsened metabolic dysfunction and cardiac impairment.

Drug screening identified formononetin as a selective ERRα activator. In mouse and pig models, formononetin increased ERRα activity, improved cardiac mitochondrial metabolism, and reduced anthracycline-associated cardiac injury. Mechanistic experiments indicated that formononetin interacts with the ERRα/PGC-1α complex and promotes its stability, supporting activation of downstream metabolic pathways.
Importantly, formononetin also demonstrated anticancer activity in human breast cancer patient-derived organoids. Treatment with formononetin alone reduced organoid viability and proliferation, while combining formononetin with doxorubicin produced greater antitumor effects.

Self-Sampling HPV Testing Increases Cervical Cancer Screening Uptake in Primary Care
A Singapore randomized trial found that offering HPV self-sampling increased cervical cancer screening uptake from 42.8% to 56.6%. More than half of screened women chose self-sampling, suggesting that flexible screening options may help reach women who otherwise remain unscreened.
KEY FINDINGS: Offering HPV self-sampling as an additional screening option substantially increased cervical cancer screening participation and high-risk HPV detection compared with clinician sampling alone in this Singapore primary care population. The benefit was particularly relevant to women who had never previously undergone screening, suggesting that providing greater choice and convenience may help reach populations that are otherwise difficult to engage. More than half of screened women in the intervention group selected self-sampling, indicating substantial acceptance of this approach. However, lower uptake among women with less educational attainment highlights the need for targeted education and engagement strategies when implementing self-sampling programs.
BACKGROUND: Cervical cancer screening remains suboptimal in Singapore, where clinician-collected HPV testing has been the standard approach. Concerns related to discomfort, privacy, embarrassment, or the clinical setting may discourage some women from participating in screening. This pragmatic randomized controlled trial evaluated whether offering self-sampling for HPV DNA testing alongside clinician sampling could increase cervical cancer screening uptake and detection of high-risk human papillomavirus (HPV) compared with clinician sampling alone.
DETAILS: The open-label, 2-arm randomized controlled trial used a Zelen design and was conducted across National Healthcare Group Polyclinics in Singapore. Women aged 30-69 years who were due for cervical cancer screening were randomly assigned 1:1 to an intervention group or usual care. Women in the intervention group were offered clinician sampling followed by self-sampling if they did not choose clinician sampling, whereas women receiving usual care were offered clinician sampling alone. The primary outcome was detection of high-risk HPV DNA, with screening uptake as the secondary outcome.

Between August 2024 and February 2025, 650 women were randomized, with 640 participants included in the final analysis, 320 in each group. Subgroup analyses evaluated outcomes according to previous screening history, while multivariable analyses examined factors associated with screening choices.
High-risk HPV detection was significantly greater when self-sampling was offered alongside clinician sampling than with clinician sampling alone: 3.1% versus 0.3%, respectively, representing an absolute difference of 2.8% (95% CI, 0.8-4.8; P<.001). The higher detection rate was driven by greater screening participation, with screening uptake reaching 56.6% in the intervention group compared with 42.8% with usual care, an absolute difference of 13.8% (95% CI, 6.0-21.4; P<.001).
The increase in screening uptake was particularly evident among women who had no previous screening and those with a regular screening history. Among women who underwent screening in the intervention group, 56.4% selected self-sampling. Lower educational attainment was associated with lower odds of choosing self-sampling rather than declining screening altogether.

Long-Term Outcomes of Azacitidine, Venetoclax, and Gilteritinib in Newly Diagnosed FLT3-Mutated Acute Myeloid Leukemia
In a phase II study of 30 patients with newly diagnosed FLT3-mutated AML, azacitidine, venetoclax, and gilteritinib produced a 96% CR/CRi rate. At a median follow-up of 41.5 months, median RFS and OS were 23.4 and 29.7 months, with 3-year rates of 43% and 46%, respectively. Baseline RAS pathway mutations were associated with poorer outcomes, while 67% of evaluable relapses lacked detectable FLT3 mutations. The triplet produced durable remissions but frequently required treatment dose or duration reductions because of myelosuppression.
KEY FINDINGS: In this phase II study, azacitidine, venetoclax, and gilteritinib produced high remission rates and encouraging long-term survival in patients with newly diagnosed FLT3-mutated AML who were unfit for intensive chemotherapy. The 3-year RFS and OS rates were 43% and 46%, respectively, although outcomes were less favorable in patients with FLT3-ITD mutations and baseline RAS pathway mutations. Most evaluable relapses were FLT3-negative, suggesting that resistance may involve mechanisms beyond persistent FLT3-mutated disease. Dose or duration reductions were frequently required during consolidation, primarily reflecting the challenge of managing myelosuppression. Randomized studies are needed to establish the role of this triplet regimen relative to current standard approaches.
BACKGROUND: Relapse after frontline azacitidine and venetoclax remains a major challenge in patients with FLT3-mutated acute myeloid leukemia (AML), with relapse often associated with expansion of FLT3-mutated clones. This phase II study evaluated the long-term efficacy and safety of adding the FLT3 inhibitor gilteritinib to azacitidine and venetoclax in adults with newly diagnosed FLT3-mutated AML who were considered unfit for intensive chemotherapy.
DETAILS: Thirty patients with newly diagnosed FLT3-mutated AML were treated with the azacitidine, venetoclax, and gilteritinib triplet regimen. The median age was 71 years, and 22 (73%) patients had FLT3-ITD mutations. Fourteen patients (47%) proceeded to allogeneic hematopoietic stem cell transplantation in first remission. The median follow-up was 41.5 months.

The complete remission or complete remission with incomplete hematologic recovery rate was 96%. Eleven patients (37%) subsequently relapsed, and among evaluable relapses, the FLT3 mutation was no longer detectable in 67%, indicating that relapse mechanisms were not necessarily driven by persistent FLT3-mutated disease.
The median relapse-free survival (RFS) was 23.4 months and median overall survival (OS) was 29.7 months. At 3 years, RFS was 43% and OS was 46%. Among patients with FLT3-ITD-mutated AML, median RFS and OS were 17.0 months and 21.8 months, respectively, with 3-year RFS and OS rates of 32% and 36%. Baseline RAS pathway mutations were associated with poorer outcomes.
Survival outcomes were similar regardless of whether patients underwent allogeneic hematopoietic stem cell transplantation in first remission. Among patients receiving at least one consolidation cycle, 68% required a reduction in the dose or duration of at least one study drug, highlighting the need to manage treatment-related myelosuppression during prolonged therapy.

Broad-Spectrum Antibiotic Use Is Lower Among Hospice Patients With Cancer at the End of Life
In this nationwide Korean cohort, hospice utilization was associated with lower broad-spectrum antibiotic use as death approached, particularly during the final week and final 3 days of life. The findings suggest that hospice involvement may be associated with a transition toward more selective antimicrobial use and less intensive treatment near the end of life. However, the study was observational, and causality cannot be established. Important clinical variables, including infection severity, microbiological findings, functional status, symptom burden, cancer stage, and treatment intent, were unavailable in the claims data.
KEY FINDINGS: Among adults with cancer approaching death, hospice utilization was associated with less frequent and lower-intensity broad-spectrum antibiotic exposure, particularly during the final days of life. The findings are consistent with a transition toward comfort-focused care, although they do not establish that hospice care itself caused the reduction. Hospice initiation occurred relatively close to death, with a mean interval of 39.9 days and a median of 22.0 days, and some antibiotic treatment may have preceded hospice enrollment. In addition, cancer stage, treatment status, infection severity, microbiological findings, functional status, symptom burden, and treatment intent were unavailable in the claims data.
BACKGROUND: Antibiotic treatment remains common during end-of-life care for patients with cancer, despite uncertain benefits for survival and potential burdens including drug toxicity, intravenous administration, adverse effects, and antimicrobial resistance. This retrospective cohort study evaluated whether hospice involvement was associated with differences in broad-spectrum antibiotic use among adults with cancer during the final 3 months of life.
DETAILS: Investigators analyzed Korean National Health Insurance Service claims data for adults aged ≥18 years who died between January 1, 2018, and December 31, 2021, with one of the 10 leading cancer-related causes of death. Hospice users had received inpatient, home-based, or consultation-based hospice care before death. Broad-spectrum antibiotic exposure included anti-pseudomonal penicillins, anti-pseudomonal cephalosporins, carbapenems, and glycopeptides. The final 90 days of life were divided into four intervals: 1–3 months before death, 1 week to 1 month before death, the final week, and the final 3 days. Antibiotic exposure was assessed by the proportion of patients receiving antibiotics and by days of therapy (DOT) per 1,000 patient-days. Propensity score matching was performed at a 1:2 ratio.

After matching, 38,102 hospice users and 75,736 non-hospice users were analyzed. During the final 3 months of life, 74.6% of hospice users and 79.0% of non-hospice users received at least one broad-spectrum antibiotic (P0.001). Antibiotic use was initially slightly higher among hospice users during the period 1–3 months before death, at 34.0% versus 32.2% (P0.001), but became consistently lower among hospice users thereafter. From 1 week to 1 month before death, use was 31.1% versus 32.8%; during the final week, 11.3% versus 18.5%; and during the final 3 days, 4.8% versus 10.3% among hospice and non-hospice users, respectively (all P0.001).
Days of therapy per 1,000 patient-days were also consistently lower among hospice users, with the greatest differences occurring during the final week and final 3 days of life. Carbapenems and glycopeptides demonstrated particularly pronounced differences between the groups. In cancer-specific analyses, patients with hematologic malignancies had the highest overall antibiotic exposure, followed by those with pancreatobiliary and gastric cancers, while exposure was comparatively lower among patients with breast and liver cancers.

Multi-Analyte Blood Test Improves Early Detection of Hepatocellular Carcinoma in Patients With Cirrhosis
In adults with cirrhosis, HelioLiver Dx demonstrated superior sensitivity to ultrasound for HCC detection, including small lesions, while maintaining non-inferior specificity. The blood-based test detected 47.8% of all HCC versus 28.3% with ultrasound and 28.6% versus 0% for lesions less than or equal to 2 cm, meeting both prespecified co-primary endpoints.
KEY FINDINGS: In a prospective multicenter validation study of 1,268 adults with cirrhosis, HelioLiver Dx demonstrated greater sensitivity than ultrasound for HCC detection, including small lesions. Sensitivity was 47.8% versus 28.3% for all HCC and 28.6% versus 0% for lesions ≤2 cm. Although specificity was lower with HelioLiver Dx, the test met prespecified criteria for superior sensitivity and non-inferior specificity.
BACKGROUND: Patients with cirrhosis who are at high risk for hepatocellular carcinoma (HCC) are recommended to undergo biannual abdominal ultrasound surveillance. However, ultrasound has limited sensitivity for small HCC lesions, and adherence to surveillance can be poor. A multianalyte cell-free DNA (cfDNA)-based blood test, HelioLiver Dx, was developed to facilitate HCC detection in this high-risk population.
DETAILS: This cross-sectional, prospective, blinded, multicenter validation study evaluated HelioLiver Dx and abdominal ultrasound in adults with cirrhosis. Participants underwent both tests, while multiphasic magnetic resonance imaging (MRI) served as the reference standard for determining HCC status. The study included 1,268 evaluable participants from 42 clinical sites in the United States.

HelioLiver Dx combines cfDNA methylation features with patient age and sex and serum concentrations of alpha-fetoprotein (AFP), AFP-L3, and des-gamma-carboxy prothrombin (DCP). The test provides a qualitative positive or negative result, with its algorithm and cutoffs established before testing of the validation cohort.
The co-primary endpoints compared HelioLiver Dx with ultrasound for sensitivity and specificity in detecting HCC. Superiority required the lower bound of the 95% confidence interval for the sensitivity difference to exceed a prespecified 5% margin, while noninferiority for specificity required the lower bound to remain above −10%.
Of the 1,268 evaluable participants, 46 (3.6%) had HCC identified by MRI. Among these, 46% had small HCC lesions ≤2 cm in diameter. HelioLiver Dx detected HCC with a sensitivity of 47.8% (95% CI 32.9-63.1), compared with 28.3% (95% CI 16.0-43.5) for ultrasound.
For HCC lesions ≤2 cm, HelioLiver Dx had a sensitivity of 28.6% (95% CI 11.3-52.2), whereas ultrasound detected 0% (95% CI 0.0-16.1). Specificity was 87.6% (95% CI 85.6-89.4) for HelioLiver Dx and 93.9% (95% CI 92.5-95.2) for ultrasound.
The HelioLiver Dx test met the prespecified co-primary endpoints for superior sensitivity and non-inferior specificity compared with ultrasound. The study also found that the blood test identified more HCC lesions overall and more early lesions than ultrasound.
