ABSTRACT

PURPOSE OF REVIEW: Cancer and cardiovascular disease are among the leading causes of morbidity and mortality in the USA. Cancer and cardiovascular disease have inflammatory underpinnings that have been associated with both the development and progression of these disease states.

RECENT FINDINGS: Inflammatory signaling has been found to be a critical event in both cardiovascular disease and cancer formation and progression. Further, many chemotherapeutic agents potentiate inflammation exacerbating existing cardiovascular disease or leading to its presence. The exact mechanisms of these interactions remain poorly understood. The proinflammatory milieu observed in both cancer and cardiovascular disease likely plays an important role in the development and potentiation of both conditions. Further evaluation of this relationship will be critical in the development of new diagnostic and therapeutic modalities.

Mediastinal gray zone lymphoma in a pregnant woman presenting with cardiac tamponade

Cardiooncology. 2023 May 31;9(1):27. doi: 10.1186/s40959-023-00173-2.

ABSTRACT

BACKGROUND: Mediastinal gray zone lymphoma is a newly recognized rare B cell neoplasm, which is challenging in diagnosis and treatment.

CASE PRESENTATION: In the current study, we aimed to report a 25-year-old pregnant woman at 25 weeks of gestation who presented with chronic cough and progressive shortness of breath, hypotension, tachycardia, and tachypnea. A large circumferential pericardial effusion with compressive effect on the right atrium and right ventricle and a large extracardiac mass with external pressure to mediastinal structures were seen on trans thoracic echocardiography. The emergency pericardiocentesis was performed with the diagnosis of cardiac tamponade. Also, CMR revealed a huge heterogeneous anterior mediastinal mass, and the pathology and the immunohistochemistry of the mass biopsy revealed gray zone lymphoma with positive CD3, CD20, CD30, CD45, PAX5, and negative CD15 expression. Three courses of chemotherapy with the CHOP regimen were performed with an acceptable response every three weeks before delivery. A caesarian section was performed at 37 weeks without any problem for the patient and fetus, and chemotherapy will be started three weeks after delivery.

CONCLUSION: Cardiac tamponade as an emergency condition occurred in this pregnant patient by malignant pericardial effusion and mediastinal mass pressure. Accurate diagnosis and on time interventions caused a significant improvement and a successful delivery.

Gefitinib Increases the Incidence of QT Prolongation in Patients with Non-Small Cell Lung Cancer

Int Heart J. 2023;64(3):365-373. doi: 10.1536/ihj.22-583.

ABSTRACT

Gefitinib (GEF) may increase the risk of corrected QT prolongation (QTc). We aimed to evaluate whether gefitinib increases the risk of corrected QT interval (QTc) prolongation and analyze the associated risk factors.A total of 122 cases of advanced EGFR-mutated non-small cell lung cancer (NSCLC) who received gefitinib therapy from January 2015 to December 2020 were evaluated. The results of at least two resting 12-lead electrocardiogram before and after gefitinib treatment were obtained. The Bazett and Fridericia formulas were used to calculate the QTc interval, and the changes of QTc interval values before and after treatment were evaluated. The correlation between gefitinib and QTc interval prolongation and related risk factors were analyzed.After gefitinib-targeted therapy, 23 patients (18.9%) had a prolonged QTc interval, which increased from a mean of 446 ± 25 ms at baseline to 478 ± 18 ms (P < 0.001). Three of the patients met criteria for Grade 3 QTc prolongation in the common term V5.0 for clinical adverse events. Univariate analysis showed that age (ORR, 1.054; 95% confidence interval [CI], 1.003-1.107; P = 0.038), history of hypertension (ORR, 3.409; 95% CI, 1.334-8.713; P = 0.01), CCB medication history (ORR, 0.259; 95% CI, 0.094-0.712; P = 0.009), history of lung cancer surgery (ORR, 0.231; 95% CI, 0.064-0.829; P = 0.025), and baseline QT interval (ORR, 0.978; 95% CI, 0.964-0.993; P = 0.004) were important predictors of QTc interval prolongation in patients treated with gefitinib. The results of multivariate analysis showed that the history of lung cancer surgery and the baseline QT interval were important factors affecting QTc interval prolongation in patients treated with gefitinib.Gefitinib increases the risk of QTc prolongation in NSCLC patients, which may be more pronounced in patients with advanced age, hypertension, CCB therapy, lung cancer surgery, and a long QT interval at baseline.

Morbidity and mortality of patients with diabetic neuropathy treated with pathogenetically oriented alpha-lipoic acid versus symptomatic pharmacotherapies - a nationwide database analysis from Hungary

Diabetes Res Clin Pract. 2023 May 29:110734. doi: 10.1016/j.diabres.2023.110734. Online ahead of print.

ABSTRACT

AIMS: Diabetic neuropathy is associated with increased risk of morbidity and all-cause mortality. It is unclear whether these outcomes differ in patients with diabetic neuropathy treated with pathogenetically oriented vs symptomatic pharmacotherapies.

METHODS: We performed a retrospective (2009-2019) database analysis of patients treated with pathogenetically oriented alpha-lipoic acid (ALA) or symptomatic pharmacotherapies for diabetic neuropathy. We investigated clinical outcomes in propensity score matched patients in Hungary. Changes in hazard ratios and annualized event rates were assessed and sensitivity analyses performed.

RESULTS: Hazard ratios favored treatment with ALA vs symptomatic pharmacotherapies regarding acute myocardial infarction (HR 0.73, 95%CI: 0.60-0.89, p = 0.0016), stroke (HR 0.71, 95%CI: 0.62-0.82, p<0.0001),<0.0001),<0.0001),

CONCLUSIONS: This retrospective database analysis revealed a lower occurrence of cardio- and cerebrovascular morbidity, cancer events and all-cause mortality in patients with diabetic neuropathy treated with pathogenetically oriented ALA vs symptomatic pharmacotherapies. This hypothesis-generating result requires further investigations.

AKR1B1 inhibition using NARI-29-an Epalrestat analogue-alleviates Doxorubicin-induced cardiotoxicity via modulating Calcium/CaMKII/MuRF-1 axis

Chem Biol Interact. 2023 May 29;381:110566. doi: 10.1016/j.cbi.2023.110566. Online ahead of print.

ABSTRACT

The clinical use of doxorubicin (Dox) is narrowed due to its carbonyl reduction to doxorubicinol (Doxol) implicating resistance and cardiotoxicity. Hence, in the present study we have evaluated the cardioprotective effect of AKR1B1 (or aldose reductase, AR) inhibitor NARI-29 (epalrestat (EPS) analogue) and its effect in the Dox-modulated calcium/CaMKII/MuRF1 axis. Initially, the breast cancer patient survival associated with AKR1B1 expression was calculated using Kaplan Meier-plotter (KM-plotter). Further, breast cancer, cardiomyoblast (H9c2), and macrophage (RAW 264.7) cell lines were used to establish the in vitro combination effect of NARI-29 and Dox. To develop the cardiotoxicity model, mice were given Dox 2.5 mg/kg (i.p.), biweekly. The effect of AKR1B1 inhibition using NARI-29 on molecular and cardiac functional changes was measured using echocardiography, fluorescence-imaging, ELISA, immunoblotting, flowcytometry, High-Performance Liquid Chromatography with Fluorescence Detection (HPLC-FD) and cytokine-bead array methods. The bioinformatics data suggested that a high expression of AKR1B1 is associated with significantly low survival of breast cancer patients undergoing chemotherapy; hence, it could be a target for chemo-sensitization and chemo-prevention. Further, in vitro studies showed that AKR1B1 inhibition with NARI-29 has increased the accumulation and sensitized Dox to breast cancer cell lines. However, treatment with NARI-29 has alleviated the Dox-induced toxicity to cardiomyocytes and decreased the secretion of inflammatory cytokines from RAW 264.7 cells. In vivo studies revealed that the NARI-29 (25 and 50 mg/kg) has prevented the functional, histological, biochemical, and molecular alterations induced by Dox treatment. Moreover, we have shown that NARI-29 has prevented the carbonyl reduction of Dox to Doxol in the mouse heart, which reduced the calcium overload, prevented phosphorylation of CaMKII, and reduced the expression of MuRF1 to protect from cardiac injury and apoptosis. Hence in conclusion, AKR1B1 inhibitor NARI-29 could be used as an adjuvant therapeutic agent with Dox to prevent cardiotoxicity and synergize anti-breast cancer activity.

Comparative arrhythmia patterns among patients on tyrosine kinase inhibitors

J Interv Card Electrophysiol. 2023 May 31. doi: 10.1007/s10840-023-01575-z. Online ahead of print.

ABSTRACT

BACKGROUND: Tyrosine kinase inhibitors (TKIs) are widely used in the treatment of hematologic malignancies. Limited studies have shown an association between treatment-limiting arrhythmias and TKI, particularly ibrutinib, a Bruton's tyrosine kinase (BTK) inhibitor. We sought to comprehensively assess the arrhythmia burden in patients receiving ibrutinib vs non-BTK TKI vs non-TKI therapies.

METHODS: We performed a retrospective analysis of consecutive patients who received long-term cardiac event monitors while on ibrutinib, non-BTK TKIs, or non-TKI therapy for a hematologic malignancy between 2014 and 2022.

RESULTS: One hundred ninety-three patients with hematologic malignancies were included (ibrutinib = 72, non-BTK TKI = 46, non-TKI therapy = 75). The average duration of TKI therapy was 32 months in the ibrutinib group vs 64 months in the non-BTK TKI group (p = 0.003). The ibrutinib group had a higher prevalence of atrial fibrillation (n = 32 [44%]) compared to the non-BTK TKI (n = 7 [15%], p = 0.001) and non-TKI (n = 15 [20%], p = 0.002) groups. Similarly, the prevalence of non-sustained ventricular tachycardia was higher in the ibrutinib group (n = 31, 43%) than the non-BTK TKI (n = 8 [17%], p = 0.004) and non-TKI groups (n = 20 [27%], p = 0.04). TKI therapy was held in 25% (n = 18) of patients on ibrutinib vs 4% (n = 2) on non-BTK TKIs (p = 0.005) secondary to arrhythmias.

CONCLUSIONS: In this large retrospective analysis of patients with hematologic malignancies, patients receiving ibrutinib had a higher prevalence of atrial and ventricular arrhythmias compared to those receiving other TKI, with a higher rate of treatment interruption due to arrhythmias.

An unusual case of checkpoint-inhibitor-induced pleuropericarditis

J Oncol Pharm Pract. 2023 May 30:10781552231179369. doi: 10.1177/10781552231179369. Online ahead of print.

ABSTRACT

INTRODUCTION: Pembrolizumab is an immune checkpoint inhibitor that promotes effector T-cell functions on malignant cells by binding to programmed cell death protein 1 (PD-1). Pembrolizumab is well tolerated in most cases with an adverse event profile consisting mainly of pruritus, fatigue, and anorexia. Cardiotoxicity comprises 1% of the total adverse events.

CASE REPORT: We present a case of a 64-year-old female with non-small cell lung cancer (NSCLC) who developed pleuropericarditis following pembrolizumab therapy.

MANAGEMENT & OUTCOME: The patient was successfully managed with colchicine, furosemide, and timely initiation of methylprednisolone with the improvement of her symptoms. The decision to discontinue pembrolizumab was made, and six months after this intervention, the patient has remained asymptomatic.

DISCUSSION: Clinicians should recognize these potential immune-mediated adverse effects to provide effective and timely management and optimize patient care.

Cancer Therapy-Related Pulmonary Hypertension: A Review of Mechanisms and Implications for Clinical Practice

Anatol J Cardiol. 2023 Jun;27(6):299-307. doi: 10.14744/AnatolJCardiol.2023.3013.

ABSTRACT

Cancer therapy-related pulmonary hypertension is a rare yet potentially fatal cardiotoxicity. However, it is a reversible cause of pulmonary hypertension if detected in its early stages. Cancer therapy-related pulmonary hypertension has been encountered in patients using tyrosine kinase inhibitors, particularly dasatinib. However, it is also well known that many agents used in cancer treatment such as alkylating agents, proteasome inhibitors, thoracic radiation exposure, and immune checkpoint inhibitors are particularly associated with pulmonary hypertension evolution. In case that history, symptoms, and clinical findings suggest a potential cancer therapy-related pulmonary hypertension, echocardiography is considered as the initial tool to detect pulmonary hypertension. If the possibility of pulmonary hypertension is high based on echocardiographic data, cancer treatment, as the initial step, should be discontinued due to its potential risks and other causes for pulmonary hypertension should be investigated thoroughly. Right heart catheterization should be the next step to establish the final diagnosis, and medical management, where appropriate, should be started without delay in these patients according to their pulmonary hypertension subgroup. There exists limited information regarding the diagnostic and management strategies of cancer therapy-related pulmonary hypertension in the current guidelines. In this review article, we aim to present current literature data on the mechanisms and management of cancer therapy-related pulmonary hypertension along with its follow-up algorithm in the setting of cardio-oncology practice.

Tumour extracellular vesicles and particles induce liver metabolic dysfunction

Nature. 2023 May 24. doi: 10.1038/s41586-023-06114-4. Online ahead of print.

ABSTRACT

Cancer alters the function of multiple organs beyond those targeted by metastasis1,2. Here we show that inflammation, fatty liver and dysregulated metabolism are hallmarks of systemically affected livers in mouse models and in patients with extrahepatic metastasis. We identified tumour-derived extracellular vesicles and particles (EVPs) as crucial mediators of cancer-induced hepatic reprogramming, which could be reversed by reducing tumour EVP secretion via depletion of Rab27a. All EVP subpopulations, exosomes and principally exomeres, could dysregulate hepatic function. The fatty acid cargo of tumour EVPs-particularly palmitic acid-induced secretion of tumour necrosis factor (TNF) by Kupffer cells, generating a pro-inflammatory microenvironment, suppressing fatty acid metabolism and oxidative phosphorylation, and promoting fatty liver formation. Notably, Kupffer cell ablation or TNF blockade markedly decreased tumour-induced fatty liver generation. Tumour implantation or pre-treatment with tumour EVPs diminished cytochrome P450 gene expression and attenuated drug metabolism in a TNF-dependent manner. We also observed fatty liver and decreased cytochrome P450 expression at diagnosis in tumour-free livers of patients with pancreatic cancer who later developed extrahepatic metastasis, highlighting the clinical relevance of our findings. Notably, tumour EVP education enhanced side effects of chemotherapy, including bone marrow suppression and cardiotoxicity, suggesting that metabolic reprogramming of the liver by tumour-derived EVPs may limit chemotherapy tolerance in patients with cancer. Our results reveal how tumour-derived EVPs dysregulate hepatic function and their targetable potential, alongside TNF inhibition, for preventing fatty liver formation and enhancing the efficacy of chemotherapy.

Chemotherapy impairs ovarian function through excessive ROS-induced ferroptosis

Cell Death Dis. 2023 May 24;14(5):340. doi: 10.1038/s41419-023-05859-0.

ABSTRACT

Chemotherapy was conventionally applied to kill cancer cells, but regrettably, they also induce damage to normal cells with high-proliferative capacity resulting in cardiotoxicity, nephrotoxicity, peripheral nerve toxicity, and ovarian toxicity. Of these, chemotherapy-induced ovarian damages mainly include but are not limited to decreased ovarian reserve, infertility, and ovarian atrophy. Therefore, exploring the underlying mechanism of chemotherapeutic drug-induced ovarian damage will pave the way to develop fertility-protective adjuvants for female patients during conventional cancer treatment. Herein, we firstly confirmed the abnormal gonadal hormone levels in patients who received chemotherapy and further found that conventional chemotherapeutic drugs (cyclophosphamide, CTX; paclitaxel, Tax; doxorubicin, Dox and cisplatin, Cis) treatment significantly decreased both the ovarian volume of mice and the number of primordial and antral follicles and accompanied with the ovarian fibrosis and reduced ovarian reserve in animal models. Subsequently, Tax, Dox, and Cis treatment can induce the apoptosis of ovarian granulosa cells (GCs), likely resulting from excessive reactive oxygen species (ROS) production-induced oxidative damage and impaired cellular anti-oxidative capacity. Thirdly, the following experiments demonstrated that Cis treatment could induce mitochondrial dysfunction through overproducing superoxide in GCs and trigger lipid peroxidation leading to ferroptosis, first reported in chemotherapy-induced ovarian damage. In addition, N-acetylcysteine (NAC) treatment could alleviate the Cis-induced toxicity in GCs by downregulating cellular ROS levels and enhancing the anti-oxidative capacity (promoting the expression of glutathione peroxidase, GPX4; nuclear factor erythroid 2-related factor 2, Nrf2 and heme oxygenase-1, HO-1). Our study confirmed the chemotherapy-induced chaotic hormonal state and ovarian damage in preclinical and clinical examination and indicated that chemotherapeutic drugs initiated ferroptosis in ovarian cells through excessive ROS-induced lipid peroxidation and mitochondrial dysfunction, leading to ovarian cell death. Consequently, developing fertility protectants from the chemotherapy-induced oxidative stress and ferroptosis perspective will ameliorate ovarian damage and further improve the life quality of cancer patients.

An integrative review of nonobvious puzzles of cellular and molecular cardiooncology

Cell Mol Biol Lett. 2023 May 23;28(1):44. doi: 10.1186/s11658-023-00451-y.

ABSTRACT

Oncologic patients are subjected to four major treatment types: surgery, radiotherapy, chemotherapy, and immunotherapy. All nonsurgical forms of cancer management are known to potentially violate the structural and functional integrity of the cardiovascular system. The prevalence and severity of cardiotoxicity and vascular abnormalities led to the emergence of a clinical subdiscipline, called cardiooncology. This relatively new, but rapidly expanding area of knowledge, primarily focuses on clinical observations linking the adverse effects of cancer therapy with deteriorated quality of life of cancer survivors and their increased morbidity and mortality. Cellular and molecular determinants of these relations are far less understood, mainly because of several unsolved paths and contradicting findings in the literature. In this article, we provide a comprehensive view of the cellular and molecular etiology of cardiooncology. We pay particular attention to various intracellular processes that arise in cardiomyocytes, vascular endothelial cells, and smooth muscle cells treated in experimentally-controlled conditions in vitro and in vivo with ionizing radiation and drugs representing diverse modes of anti-cancer activity.

Integrative transcriptomics and cell systems analyses reveal protective pathways controlled by Igfbp-3 in anthracycline-induced cardiotoxicity

FASEB J. 2023 Jun;37(6):e22977. doi: 10.1096/fj.202201885RR.

ABSTRACT

Anthracyclines such as doxorubicin (Dox) are effective chemotherapeutic agents; however, their use is hampered by subsequent cardiotoxicity risk. Our understanding of cardiomyocyte protective pathways activated following anthracycline-induced cardiotoxicity (AIC) remains incomplete. Insulin-like growth factor binding protein (IGFBP) 3 (Igfbp-3), the most abundant IGFBP family member in the circulation, is associated with effects on the metabolism, proliferation, and survival of various cells. Whereas Igfbp-3 is induced by Dox in the heart, its role in AIC is ill-defined. We investigated molecular mechanisms as well as systems-level transcriptomic consequences of manipulating Igfbp-3 in AIC using neonatal rat ventricular myocytes and human-induced pluripotent stem cell-derived cardiomyocytes. Our findings reveal that Dox induces the nuclear enrichment of Igfbp-3 in cardiomyocytes. Furthermore, Igfbp-3 reduces DNA damage, impedes topoisomerase IIβ expression (Top2β) which forms Top2β-Dox-DNA cleavage complex leading to DNA double-strand breaks (DSB), alleviates detyrosinated microtubule accumulation-a hallmark of increased cardiomyocyte stiffness and heart failure-and favorably affects contractility following Dox treatment. These results indicate that Igfbp-3 is induced by cardiomyocytes in an effort to mitigate AIC.

Patient-reported ability to walk 4 m and to wash: New clinical endpoints and predictors of survival in patients with pre-terminal cancer

J Cachexia Sarcopenia Muscle. 2023 May 24. doi: 10.1002/jcsm.13247. Online ahead of print.

ABSTRACT

BACKGROUND: Maintaining the ability to perform self-care is a critical goal in patients with cancer. We assessed whether the patient-reported ability to walk 4 m and wash oneself predict survival in patients with pre-terminal cancer.

METHODS: We performed a prospective observational study on 169 consecutive hospitalized patients with cancer (52% female, 64 ± 12 years) and an estimated 1-12 months prognosis at an academic, inpatient palliative care unit. Patients answered functional questions for 'today', 'last week', and 'last month', performed patient-reported outcomes (PROs), and physical function assessments.

RESULTS: Ninety-two (54%) patients reported the ability to independently walk 4 m and 100 (59%) to wash 'today'. The median number of days patients reported the ability to walk 4 m and wash were 6 (IQR 0-7) and 7 (0-7) days ('last week'); and 27 (5-30) and 26 (10-30) days ('last month'). In the last week, 32% of patients were unable to walk 4 m on every day and 10% could walk on 1-3 days; 30% were unable to wash on every day and 10% could wash on 1-3 days. In the last months, 14% of patients were unable to walk 4 m on every day and 10% could only walk on 1-10 days; 12% were unable to wash on every day and 11% could wash on 1-10 days. In patients who could walk 'today' average 4 m gait speed was 0.78 ± 0.28 m/s. Patients who reported impaired walking and washing experienced more symptoms (dyspnoea, exertion, and oedema) and decreased physical function (higher Eastern Cooperative Oncology Group Performance Status, and lower Karnofsky Performance Status and hand-grip strength [unable vs. able to walk 'today': 205 ± 87 vs. 252 ± 78 Newton, P = 0.001; unable vs. able to wash 'today': 204 ± 86 vs. 250 ± 80 Newton, P = 0.001]). During the 27 months of observation, 152 (90%) patients died (median survival 46 days). In multivariable Cox proportional hazards regression analyses, all tested parameters were independent predictors of survival: walking 4 m 'today' (HR 0.63, P = 0.015), 'last week' (per 1 day: HR 0.93, P = 0.011), 'last month' (per 1 day: HR 0.98, P = 0.012), 4 m gait speed (per 1 m/s: HR 0.45, P = 0.002), and washing 'today' (HR 0.67, P = 0.024), 'last week (per 1 day HR 0.94, p=0.019), and 'last month' (per 1 day HR 0.99, P = 0.040). Patients unable to walk and wash experienced the shortest survival and most reduced functional status.

CONCLUSIONS: In patients with pre-terminal cancer, the self-reported ability to walk 4 m and wash were independent predictors of survival and associated with decreased functional status.

Correlation between high-resolution computed tomography appearance and histopathological features in the diagnosis of interstitial lung diseases. A real-life study

Minerva Surg. 2023 May 23. doi: 10.23736/S2724-5691.23.09948-3. Online ahead of print.

ABSTRACT

BACKGROUND: According to current guidelines, a surgical biopsy is rarely required when a high-confidence radiologic interstitial lung disease (ILD) diagnosis is made on thin-section high-resolution computed tomography (HRCT). Nevertheless, disowning HRCT scans diagnosed by biopsy are more common than presumed. Our study aimed to describe the concordance rate between HRCT scans and pathological diagnoses of ILDs obtained by surgical biopsy. The current guideline suggests the use of surgical lung biopsy (SLB) in patients with newly detected ILD of unknown cause.

METHODS: Patients who underwent mini-invasive surgical biopsies for interstitial lung diseases from January 2018 to August 2022 were analyzed. The HRCT scans were reviewed by an observer blinded to the patient's clinical information. The concordance between histological and HRCT-scan were assessed.

RESULTS: Data from 104 patients with uncertain low confidence diagnosis of interstitial lung diseases at HRCT were analyzed. Most of the patients are male (65; 62.5%). The more frequent HRCT pattern were: alternative diagnoses (46; 44.23%), UIP probable (42; 40.38%), UIP indeterminate (7; 6.73%), and non-specific interstitial pneumonia (NSIP) (9, 8.65%). The more common histological diagnosis was UIP definite (30; 28.84%), hypersensitivity pneumonia [HP](19; 18.44%), NSIP (15; 14.42%), sarcoidosis (10; 9.60%). In 7 (20%) cases, the final pathological finding denies HRCT-scans diagnoses; indeed, a moderate agreement was observed between HRCT-scan findings and the definitive histological diagnosis (kappa index: 0.428).

CONCLUSIONS: HRCT-scan has limitations if the objective is to define interstitial lung diseases accurately. Consequently, pathological assessment should be taken into account in order to provide more accurate tailored treatment strategies because the risk is to wait from 12 to 24 months to ascertain if the ILD will be treatable as progressive pulmonary fibrosis (PPF). Undeniably true, video-assisted surgical lung biopsy (VASLB) with endotracheal intubation and mechanical ventilation is associated with a risk of mortality and morbidity that is far from nil. Nevertheless, in recent years a VASLB approach performed in awake subjects under loco-regional anesthesia (awake-VASLB) has been suggested as an effective method to obtain a highly confident diagnosis in patients with diffuse pathologies of the lung parenchyma.

Diastolic function assessment with left atrial strain in long-term survivors of childhood acute lymphoblastic leukemia

Rev Esp Cardiol (Engl Ed). 2023 May 20:S1885-5857(23)00138-X. doi: 10.1016/j.rec.2023.05.001. Online ahead of print.

ABSTRACT

BACKGROUND AND OBJECTIVES: Survivors of childhood cancer might be at increased risk of diastolic dysfunction at follow-up due to exposure to cardiotoxic treatment. Although assessment of diastolic function is challenging in this relatively young population, left atrial strain might provide a novel insight in this evaluation. Our aim was to examine diastolic function in a cohort of long-term survivors of childhood acute lymphoblastic leukemia by using left atrial strain and conventional echocardiographic parameters.

METHODS: Long-term survivors who were diagnosed at a single center between 1985 and 2015 and a control group of healthy siblings were recruited. Conventional diastolic function parameters and atrial strain were compared, and the latter was measured during the 3 atrial phases: reservoir (PALS), conduit (LACS) and contraction (PACS). Inverse probability of treatment weighting was used to account for differences between the groups.

RESULTS: We analyzed 90 survivors (age, 24.6 ± 9.7 years, time since diagnosis 18 [11-26] years) and 58 controls. PALS and LACS were significantly reduced compared with the control group: 46.4 ± 11.2 vs 52.1 ± 11.7; P = .003 and 32.5 ± 8.8 vs 38.2 ± 9.3; P = .003, respectively. Conventional diastolic parameters and PACS were similar between the groups. The reductions in PALS and LACS were associated with exposure to cardiotoxic treatment in age- and sex-adjusted analysis (≥ moderate risk, low risk, controls): 45.4 ± 10.5, 49.5 ± 12.9, 52.1 ± 11.7; Padj = .003, and 31.7 ± 9.0, 35.2 ± 7.5, 38.2 ± 9.3; Padj = .001, respectively.

CONCLUSIONS: Long-term childhood leukemia survivors showed a subtle impairment of diastolic function that was detected with atrial strain but not with conventional measurements. This impairment was more pronounced in those with higher exposure to cardiotoxic treatment.

Severe sotorasib-related hepatotoxicity and non-liver adverse events associated with sequential anti-PD(L)1 and sotorasib therapy in KRASG12C-mutant lung cancer

J Thorac Oncol. 2023 May 20:S1556-0864(23)00572-5. doi: 10.1016/j.jtho.2023.05.013. Online ahead of print.

ABSTRACT

INTRODUCTION: Sequential anti-PD-(L)1 followed by small targeted therapy use is associated with increased prevalence of adverse events (AEs) in non-small cell lung cancer (NSCLC). KRASG12C inhibitor sotorasib may trigger severe immune-mediated hepatotoxicity when used in sequence or in combination with anti-PD-(L)1. This study was designed to address whether sequential anti-PD-(L)1 and sotorasib therapy increases the risk of hepatotoxicity and other AEs.

METHODS: This is a multicenter, retrospective study of consecutive advanced KRASG12C-mutant NSCLC treated with sotorasib outside clinical trials in 16 French medical centers. Patient records were reviewed to identify sotorasib-related AEs (NCI-CTCAE v5.0). Grade 3 and higher AE was considered as severe. Sequence group was defined as patients who received an anti-PD-(L)1 as last line of treatment before sotorasib initiation and control group as patients who did not receive an anti-PD-(L)1 as last line of treatment before sotorasib initiation.

RESULTS: We identified 102 patients who received sotorasib, including 48 (47%) in sequence group and 54 (53%) in control group. Patients in control group received an anti-PD-(L)1 followed by at least one treatment regimen before sotorasib in 87% of the cases or did not receive an anti-PD-(L)1 at any time before sotorasib in 13% of the cases. Severe sotorasib-related AEs were significantly more frequent in sequence group compared to control group (50% vs 13%, p<0.001).<0.001).

CONCLUSIONS: Sequential anti-PD-(L)1 and sotorasib therapy is associated with a significantly increased risk of severe sotorasib-related hepatotoxicity and severe non-liver AEs. We suggest avoiding starting sotorasib within 30 days from the last anti-PD-(L)1 infusion.
