ABSTRACT

Primary central nervous system tumors rank 8 among other cancers in patients over 40 years of age. Glioblastoma is the most common primary central nervous system malignancy, accounting for 48 percent of the cases. The present study evaluates the effect of bevacizumab on the disease course in patients who received bevacizumab therapy due to primary central nervous system tumors in our clinic. The study was designed as a retrospective study. The records of patients treated between January 2000 and August 2021 were reviewed and patients who received bevacizumab therapy due to primary central nervous system tumor were included in the study to evaluate the effect of the therapy on disease course among the subgroups of patients. The study included 70 patients. Of these patients, 40 were male (57.1%) and 30 (42.9%) were female. The median duration of follow-up was 28 months (8-209 months). The median age of the patients was 47 years. The median duration of exposure to bevacizumab was 5 months (1-33 months). Forty-nine patients (71.4%) were histologically diagnosed with glioblastoma multiforme. The median progression-free survival (PFS) was 5 months (95% confidence interval 4-6). The median overall survival (OS) was 8 months (95% confidence interval 6.97-9.02). No statistically significant difference in OS or PFS was observed in any patient subgroup. The therapy was discontinued only in 2 patients (2.9%) due to side effects (1 patient with pulmonary embolism and 1 patient with intracranial hemorrhage). The present study found that the use of bevacizumab is safe in terms of side effects. No statistically significant difference in OS or PFS was observed in any patient subgroup. There is a need for studies on a larger number of patients to find out which patient subgroup benefit the most from bevacizumab therapy.

Non-coding RNAs, cancer treatment and cardiotoxicity: A triad of new hope

Cancer Treat Res Commun. 2023 Jul 28;36:100750. doi: 10.1016/j.ctarc.2023.100750. Online ahead of print.

ABSTRACT

The global health landscape has experienced a shift towards non-communicable diseases, with cardiovascular diseases and cancer as leading causes of mortality. Although advancements in healthcare have led to an increase in life expectancy, they have concurrently resulted in a greater burden of chronic health conditions. Unintended consequences of anticancer therapies on various tissues, particularly the cardiovascular system, contribute to elevated morbidity and mortality rates that are not directly attributable to cancer. Consequently, the field of cardio-oncology has emerged to address the prevalence of CVD in cancer survivors and the cardiovascular toxicity associated with cancer therapies. Non-coding RNAs (ncRNAs) have been found to play a crucial role in early diagnosis, prognosis, and therapeutics within the realm of cardio-oncology. This comprehensive review evaluates the risk assessment of cancer survivors concerning the acquisition of adverse cardiovascular consequences, investigates the association of ncRNAs with CVD in patients undergoing cancer treatment, and delves into the role of ncRNAs in the diagnosis, treatment, and prevention of CVD in patients with a history of anti-cancer therapy. A thorough understanding of the pathogenesis of cancer therapy-related cardiovascular disease and the involvement of ncRNAs in cardio-oncology will enable healthcare professionals to provide anticancer treatment with minimized cardiovascular side effects, thereby improving patient outcomes. Ultimately, this comprehensive analysis aims to provide valuable insights into the complex interplay between cancer and cardiovascular diseases, facilitating the development of more effective diagnostic, therapeutic, and preventive strategies in the burgeoning field of cardio-oncology.

The protective effect of thiolutin on doxorubicin-induced H9c2 cardiomyocyte injury

J Toxicol Sci. 2023;48(8):469-479. doi: 10.2131/jts.48.469.

ABSTRACT

The use of doxorubicin (DOX) may contribute to cardiotoxicity, limiting its clinical application. Thiolutin (THL) has been found to exert protective roles in various biological activities, while its effects on DOX-induced cardiotoxicity are still uncovered. Cell counting kit 8 assay was utilized to detect cell viability and half maximal inhibitory concentration of THL in H9c2 cardiomyocytes. The level of lactate dehydrogenase (LDH), adenosine triphosphate (ATP), interleukin (IL)-18 and IL-1 beta (IL-1β) were measured using the corresponding detection kits, and flow cytometry determined cell apoptosis rate. The reactive oxygen species (ROS) accumulation was evaluated by utilizing immunofluorescence or flow cytometry assay. The protein levels of NLR family Pyrin domain 3 (NLRP3), pro-Caspase1, cleaved-Caspase1, gasdermin D (GSDMD) and cleaved-GSDMD (GSDMD-N) in H9c2 cells were detected by immunoblotting assay. The treatment of THL reduced H9c2 cell viability in a gradient-dependent manner. THL treatment reversed the DOX-induced inhibition of proliferation, decrease of ATP, up-regulation of LDH, IL-18, IL-1β and production of ROS, activation of NLRP3 and inflammasome-mediated pyroptosis in H9c2 cells. Additionally, NLRP3 knockdown abolished the effects of THL in DOX-treated H9c2 cells remarkably. This investigation proved that THL notably ameliorated DOX-induced apoptosis, oxidative stress, and pyroptosis in H9c2 cardiomyocytes. Besides, THL effectively inactivated DOX-induced NLRP3 inflammasome in H9c2 cells. These findings revealed a promising drug to assist DOX in its anti-cancer effects and protect the heart of patients.

Diagnostic Value of Three-Dimensional Speckle Tracking Imaging Strain Parameters for Detection of Cancer Chemotherapy-Related Cardiac Dysfunction: A Meta-Analysis

Arq Bras Cardiol. 2023 Jul;120(8):e20220370. doi: 10.36660/abc.20220370.

ABSTRACT

BACKGROUND: Chemotherapeutic agents (e.g., anthracyclines, trastuzumab) commonly used for treating malignant tumors have been demonstrated to have cardiotoxic effects, which is associated with poor prognosis. Three-dimensional echocardiography has been used to predict cancer chemotherapy-induced cardiac dysfunction.

OBJECTIVES: Evaluation of the diagnostic performance of strain parameters, global area strain (GAS), longitudinal strain (GLS), circumferential strain (GCS), and radial strain (GRS) by meta-analysis.

METHODS: Relevant studies were searched from the Embase, PubMed, and Web of Science databases. Statistical analysis was performed using Stata 12. The summary receiver operating characteristic curve, sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), and corresponding 95% confidence interval for the four strain parameters were pooled. P<0.05

RESULTS: Nine studies involving 650 participants were included. GAS and GLS showed significant diagnostic advantages over GCS and GRS. For GAS, the sensitivity was 0.85 (0.70, 0.93) and specificity was 0.82(0.78, 0.86) with PLR of 4.76 (3.55, 6.39) and NLR of 0.18 (0.09, 0.39) and an area under the curve (AUC) of 0.85 (0.82, 0.88). For GLS, the sensitivity was 0.81 (0.74, 0.86) and specificity was 0.81(0.68, 0.90) with PLR of 4.35(2.42, 7.80) and NLR of 0.23 (0.17, 0.33) and an AUC of 0.85 (0.82, 0.88). The GCS showed a sensitivity of 0.63 and a specificity of 0.79 with an AUC of 0.77. The GRS showed a sensitivity of 0.74 and a specificity of 0.66 with an AUC of 0.73.

CONCLUSION: 3D-STI strain parameters GAS and GLS showed good performance in detecting early cardiac dysfunction in patients with tumors receiving chemotherapy.

Cardiorenal Syndrome: A Literature Review

Cureus. 2023 Jul 1;15(7):e41252. doi: 10.7759/cureus.41252. eCollection 2023 Jul.

ABSTRACT

Cardiorenal syndrome (CRS) is a condition characterized by the intricate two-way relationship between the heart and kidneys, which can lead to acute or chronic dysfunction in these organs. The interplay between cardiorenal connectors and both hemodynamic and non-hemodynamic factors is crucial to understanding this syndrome. The clinical importance of these interactions is evident in the changes observed in hemodynamic factors, neurohormonal markers, and inflammatory processes. Identifying and understanding biomarkers associated with CRS is valuable for early detection and enabling intervention before significant organ dysfunction occurs. This comprehensive review focuses on the clinical significance of biomarkers in the diagnosis, prognosis, and management of CRS. Finally, it highlights the necessity for further advancements in managing this condition.

Late-onset cardiotoxicity in patients with HER2-positive metastatic breast cancer receiving trastuzumab-based therapy

J Oncol Pharm Pract. 2023 Aug 1:10781552231193149. doi: 10.1177/10781552231193149. Online ahead of print.

ABSTRACT

INTRODUCTION: Patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC) typically receive long-term trastuzumab treatment for several years. The aim of our study is to identify the incidence and characterize late-onset cardiotoxicity in patients with HER2-positive MBC receiving trastuzumab-based therapy.

METHODS: We retrospectively reviewed charts of HER2-positive MBC patients who received >1 year of trastuzumab-based therapy at the Massachusetts General Hospital Cancer Center over three-year period. The primary endpoint was development of trastuzumab-induced cardiotoxicity (TIC). Secondary endpoints included time to TIC development, incidence/duration of trastuzumab interruption due to TIC, incidence of permanent discontinuation of trastuzumab due to TIC, clinic visit, or hospitalization due to TIC.

RESULTS: Thirty-seven patients were included. Mean age was 56 years (range: 33-78 years, SD 9.5). Seven patients received prior doxorubicin and 14 patients received previous or concurrent breast irradiation. Mean duration of trastuzumab-based therapy was 57 months (range: 14-140 months, SD 39.3). Seven patients (18.9%) experienced TIC resulting in treatment interruption for two patients (28 and 78 days). The median time from starting trastuzumab therapy to TIC was 14 months (interquartile range: 11-29.5 months). The mean number of left ventricular ejection fraction (LVEF) assessment completed per year was 2.7 (range: 1.2-6.6, SD 1.1).

CONCLUSION: Cardiotoxicity occurred in a minority of patients with HER2-positive MBC receiving trastuzumab-based therapy for more than one year. LVEF reductions to below the institutional lower limit of normal and therapy modifications were uncommon.
