Advances in cancer therapeutics have substantially improved survival across multiple malignancies but have concurrently increased the burden of cancer therapy–related cardiovascular toxicity, establishing cardio-oncology as an essential discipline situated at the interface of oncology and cardiovascular medicine. Despite growing incorporation of cardiac imaging and circulating cardiac biomarkers into surveillance strategies, current approaches remain limited by modest specificity, heterogeneous risk profiles, and inconsistent translation into effective cardioprotective interventions. This review synthesizes contemporary evidence on the biological mechanisms underlying cancer therapy–related cardiovascular toxicity and critically evaluates the current role and limitations of established cardiac biomarkers, including high-sensitivity cardiac troponins and natriuretic peptides, in risk stratification and early injury detection. We further examine why many cardioprotective clinical trials have yielded neutral or modest results, highlighting signal dilution arising from low-risk populations, endpoint heterogeneity, and timing mismatches between injury biology and intervention. This review advances a precision cardio-oncology framework by integrating tumor-derived liquid biopsy platforms—such as circulating tumor DNA, tissue-specific cell-free DNA, and extracellular vesicles—with cardiac biomarkers to provide a biologically contextualized assessment of cardiovascular risk. Tumor-derived biomarkers may reflect treatment intensity, systemic inflammatory burden, and cardiotoxic susceptibility, thereby enhancing the interpretation of cardiac biomarker signals and refining patient selection for targeted cardioprotective strategies.

Abstract Advancements in the understanding of chronic lymphocytic leukemia (CLL) have transformed patient care, leading to the development of novel targeted therapies. Traditionally, patient fitness for treatment was based on the tolerability of chemoimmunotherapy such as fludarabine–cyclophosphamide–rituximab. As the CLL patient population is predominantly older, age has historically been a major factor in how a physician selects a patient's treatment. However, as a patient's fitness goes beyond age, the definition of patient fitness should also evolve. Here, we provide suggestions for the current best practice on assessing fitness for treating CLL. Considerations for treatment include assessment of polypharmacy, history of infections, cardiovascular and renal comorbidities, functional status, cognitive and psychological status, nutritional status, and social support. The flow of assessments can start with a typical clinical evaluation followed by geriatric, cardiovascular, and renal reviews, if needed, and include collecting a patient's full history to evaluate their risk of complications with specific CLL treatments. The severity of a patient's cardiovascular profile can range from low to high risk; for those at high risk, collaboration with a cardiologist is recommended. Geriatric assessment is advised to determine baseline frailty and resilience to tolerate treatments, to avoid inappropriate treatment or undertreating patients based on chronological age, and to align the patient's fitness status with the most optimal treatment. Continuous monitoring and assessment, regardless of therapy, are recommended. Patient preferences are also integral to this decision‐making process. Looking beyond a patient's age and basing treatment selection on their fitness is key in the new era of treatment in CLL.

Sickle cell disease (SCD) is the most common genetic haemoglobinopathy worldwide. Due to advancements in care, SCD patients are living longer. Consequently, there is increased interest in long term sequalae of chronic micro-vascular sickling and resultant end organ damage. Sickle cell cardiomyopathy is an emerging clinical entity characterised by a unique combination of ventricular dilatation, ventricular hypertrophy, diastolic dysfunction and pulmonary hypertension. Additionally, SCD patients have impaired autonomic function which is thought to pre-dispose to vaso-occlusive crises through sympathetic activation and parasympathetic withdrawal during times of physiologic stress. Furthermore, sudden death is a major cause of mortality among patients with SCD, however the mechanism has not been elucidated. This review summarizes the sickle cell cardiomyopathy literature, its relationship with autonomic dysfunction and its association with sudden death.

Background: Facial appearance influences social perception, with laypersons focusing on the central facial triangle; nasal differences may alter gaze patterns, but few studies have quantified this using eye-tracking. Objective: To evaluate how layperson gaze patterns shift in response to different nasal variations as measured by eye-tracking. Methods: In this prospective cohort study, facial images with 30 nasal differences were created using Photoshop to represent a range of phenotypes, such as dorsal hump, crooked nose, and pinched tip, alongside controls. Gaze data were captured via eye-tracking, and linear mixed-effects modeling assessed differences in time spent viewing defined areas of interest, adjusting for participant and image variables. Results: A total of 119 participants (53.8% female) were enrolled. The median age was 40 years, and 82% identified as Caucasian. Among the 30 nasal alterations, only the saddle nose resulted in significantly increased gaze time compared to controls (mean increase: 0.89 s; p < 0.001). Participant age, sex, and gender of the face in the image did not significantly influence gaze behavior. Conclusion: In this study, only the saddle nose attracted greater visual attention from lay observers compared with other nasal variants.

Background/Objectives: We performed a systematic review of preclinical literature on the use of high-LET particle therapy, DDRi, and/or immunotherapy specifically in pMMR colorectal cancer. Methods: A systematic review of the literature published between 2014 and 2025 was conducted across major databases. Studies were included if they examined particle radiotherapy (e.g., proton, alpha, and carbon) or X-ray radiation either alone or in combination with DDRi and/or immune checkpoint inhibitors (ICIs) in pMMR colorectal cancer models. Results: In total, 131 studies met the inclusion criteria, including 70 preclinical studies. These studies consistently demonstrate that high-LET radiation amplifies immunogenic cell death, increases cGAS-STING pathway activation, and enhances tumor antigen presentation, thereby fostering greater immune infiltration and systemic antitumor responses. Concurrent irradiation with DDRi enhances persistent DNA damage and cytosolic DNA accumulation. In murine models, high-LET therapies show excellent local control, with manageable toxicity profiles. Combination regimens with ICIs exhibit improved local control and elicit systemic antitumor immune responses. Conclusions: High-LET particle radiation and/or the use of concurrent DDRi with ICI have significant preclinical evidence of immunostimulatory effects in pMMR rectal adenocarcinoma and increased response rates to immunotherapy. The clinical evidence will be reviewed in the companion manuscript.

Background/Objectives: Hypofractionated ablative radiation is an increasingly popular option for patients with hepatocellular carcinoma (HCC). However, concern remains about the risk for radiation-induced liver toxicity in patients with decompensated liver function. Methods: We retrospectively identified patients with underlying Child-Pugh (CP) B or C liver function treated at our University and Veterans Affairs (VA) departments from 2014 to 2019. Primary endpoints included treatment-related toxicity and dosimetric parameters. Results: 38 patients were included in the analysis. Most patients (98%) had CP B or Albumin-Bilirubin (ALBI) grade 2–3 (100%) liver disease. The median dose was 50 Gy (range 30–50) delivered in 5 or 10 fractions. Most patients had a single tumor treated (66%) with a median size of 3.1 cm (Interquartile Range (IQR) 2.3–4.1). The mean liver dose was 9.28 Gy (IQR 6.76–13.64) with a liver D800cc of 3.99 Gy (IQR 1.41–8.02). All patients completed their intended course with a median follow-up of 43 months. Four patients (10.3%) developed non-classical radiation-induced liver disease (RILD), comparable to the rate for patients with CP A function treated contemporaneously (8.3%). Otherwise, one patient (2.6%) experienced acute grade 3+ (non-RILD) hepatobiliary toxicity, while one patient (2.6%) experienced late grade 3+ hepatobiliary toxicity. Local control was promising with 2-year freedom from progression in the treated lesion of 73% (95% CI 38–91%). Median overall survival was 12 months (95% CI 5–25 months). Conclusions: Ablative radiation for patients with decompensated liver function and HCC appears well tolerated with low rates of RILD and encouraging local control. With careful selection, these patients should be considered for inclusion in future randomized trials.

CD19-directed chimeric antigen receptor (CAR) T-cell therapies have been instrumental in improving outcomes of refractory or relapsed B-cell malignancies. However, there have been safety concerns due to recent reports of second primary malignancies (SPMs) related to CAR T-cell therapies. We reviewed articles from Embase, PubMed, and Cochrane Library records and included SPM case reports as well as cohort studies. Across published cohorts, secondary cutaneous or peripheral T-cell lymphoma (PTCL) after diffuse large B-cell lymphomas (DLBCLs) have been reported at low incidence (generally in the low single-digit percentage range). While CAR T-cell therapy is associated with these rare secondary malignancies and lineage-switch events primarily described in acute leukemia, they are clinically significant and have resulted in increased surveillance. The currently available evidence suggests that most secondary malignancies after CAR T-cell therapy are due to background risk and prior treatment exposures rather than direct CAR T-cell therapy induced oncogenesis. However, rare CAR T-cell therapy-associated second primary T-cell malignancies have been reported. To properly define incidence, mechanisms, and risk factors for CAR T-cell therapy-associated malignancies, continued prospective registry follow-up and additional research will be needed.

Intramedullary screw fixation (ISF) of metacarpal fractures is a well-established technique. Prior techniques either involve placement of the intramedullary screw in a retrograde fashion or placement of the guidewire in a retrograde fashion before placing the screw in an antegrade fashion. While effective, previously described techniques have risks of extensor tendon irritation, articular cartilage disruption, and limited access to multiple metacarpals from a single incision. We present a novel antegrade intramedullary screw placement and antegrade guidewire technique for ISF that avoids disruption of the metacarpal head and allows for access to multiple metacarpals through a single incision. Cadaveric evaluation confirmed consistent sparing of the distal carpal row and demonstrated the feasibility of this technique across the index through small finger metacarpals. Compared with previously described methods, this technique offers improved soft tissue preservation, reduced risk of tendon scarring, and enhanced surgical efficiency. Level of Evidence: Level IV—case report; cadaveric study.
