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.

Prognosis of immune checkpoint inhibitors-induced myocarditis: a case series

J Immunother Cancer. 2023 May;11(5):e004792. doi: 10.1136/jitc-2022-004792.

ABSTRACT

BACKGROUND: Immune checkpoint inhibitors (ICI) have transformed cancer treatment over the last decade. Alongside this therapeutic improvement, a new variety of side effects has emerged, called immune-related adverse events (irAEs), potentially affecting any organ. Among these irAEs, myocarditis is rare but life-threatening.

METHODS: We conducted a multicenter cross-sectional retrospective study with the aim of better characterizing ICI-related myocarditis. Myocarditis diagnosis was based on the recent consensus statement of the International Cardio-Oncology Society.

RESULTS: Twenty-nine patients were identified, from six different referral centers. Most patients (55%) were treated using anti-programmed-death 1, rather than ICI combination (35%) or anti-programmed-death-ligand 1 (10%). Transthoracic echocardiography was abnormal in 52% of them, and cardiac magnetic resonance showed abnormal features in 14/24 patients (58%). Eleven patients (38%) were classified as severe. Compared with other patients, they had more frequently pre-existing systemic autoimmune disease (45% vs 6%, p=0.018), higher troponin level on admission (42-fold the upper limit vs 3.55-fold, p=0.001), and exhibited anti-acetylcholine receptor autoantibodies (p=0.001). Seven patients (24%) had myocarditis-related death, and eight more patients died from cancer progression during follow-up. Twenty-eight patients received glucocorticoids, 10 underwent plasma exchanges, 8 received intravenous immunoglobulins, and 5 other immunosuppressants. ICI rechallenge was performed in six patients, with only one myocarditis relapse.

DISCUSSION: The management of ICI-related myocarditis may be challenging and requires a multidisciplinary approach. Prognostic features are herein described and may help to allow ICI rechallenge for some patients with smoldering presentation, after an accurate evaluation of benefit-risk balance.
