ABSTRACT

The exact incidence of cancer-associated venous thromboembolism (CA-VTE) in patients with oral and facial cancer (OFC) is not exactly known, and this risk is empirically considered to be low. However, this suggestion may result in disease underdiagnosis, prolong the initiation of adequate therapy, and consecutively increase CA-VTE-related morbidity and mortality. In addition, there might be specific clinical problems in the treatment of CA-VTE in patients with oral and facial cancer, such as swallowing difficulties, that might limit the possibilities of oral anticoagulation. Finally, there are limited data regarding the optimal treatment of CA-VTE in patients with oral and facial cancer, and this includes data on novel therapeutic strategies, including the use of direct oral anticoagulants. This article reviews current data on the optimal treatment strategy for CA-VTE in patients with OFC.

Venous Thromboembolism and Primary Thromboprophylaxis in Perioperative Pancreatic Cancer Care

Cancers (Basel). 2023 Jul 8;15(14):3546. doi: 10.3390/cancers15143546.

ABSTRACT

Recent studies have shown that patients with pancreatic ductal adenocarcinoma (PDAC) treated with neoadjuvant chemo(radio)therapy followed by surgery have an improved outcome compared to patients treated with upfront surgery. Hence, patients with PDAC are more and more frequently treated with chemotherapy in the neoadjuvant setting. PDAC patients are at a high risk of developing venous thromboembolism (VTE), which is associated with decreased survival rates. As patients with PDAC were historically offered immediate surgical resection, data on VTE incidence and associated preoperative risk factors are scarce. Current guidelines recommend primary prophylactic anticoagulation in selected groups of patients with advanced PDAC. However, recommendations for patients with (borderline) resectable PDAC treated with chemotherapy in the neoadjuvant setting are lacking. Nevertheless, the prevention of complications is crucial to maintain the best possible condition for surgery. This narrative review summarizes current literature on VTE incidence, associated risk factors, risk assessment tools, and primary thromboprophylaxis in PDAC patients treated with neoadjuvant chemo(radio)therapy.

Cancer Therapy-Related Cardiotoxicity: A Comprehensive Retrospective Analysis at Najran Cancer Center, Saudi Arabia

Cureus. 2023 Jul 2;15(7):e41287. doi: 10.7759/cureus.41287. eCollection 2023 Jul.

ABSTRACT

Background Cardiotoxicity, produced as an adverse effect of anticancer therapy, is a common issue during cancer treatment. Acute coronary syndrome, myocarditis, arrhythmias, or heart failure can all be symptoms of this issue. Little is known about its occurrence among Saudi Arabian cancer patients. This study aims to investigate factors linked to anticancer therapy-related cardiotoxicity. Methods A retrospective study was conducted from April 2020 to May 2022 at the King Khalid Hospital, Najran, Saudi Arabia. The study included adult cancer patients receiving anticancer therapy, regardless of their cardiovascular disease history. Univariate analysis was used to investigate factors associated with the occurrence of cardiotoxicity related to anticancer therapy. Results Of 78 patients receiving anticancer therapy, cardiotoxicity occurred in 12 (15.4%) patients. The mean age was 56.5 ± 13.4 years, with 33.3% aged over 65 years. Comorbidities included hypertension (44; 56.4%), diabetes (41; 52.6%), dyslipidemia (13; 16.7%), smoking (16; 20.5%), heart disease (6; 7.7%), trastuzumab use (9; 11.5%), and chronic kidney disease (2; 2.6%). The most common cancers were breast cancer and gastrointestinal cancer (27.6% each). Monoclonal anticancer agents 35 (46.1%) and alkylating agents 29 (38.2%) were commonly used chemotherapies. Cardiac protective agents were used in 16 (21.1%) of patients, with angiotensin-converting enzyme (ACE) inhibitors 15 (19.7%) and statins (13; 17.1%) being the most prescribed. Baseline ejection fraction (EF) was normal in 69 (90.8%) of cases. The follow-up duration was 1.93 ± 1.90 years. A drop in EF occurred in five (6.6%) of cases. Dyslipidemia (OR: 0.12; 95% CI: 0.03-0.47, p=0.002), previous heart disease (OR: 0.14; 95% CI: 0.02-0.81, p=0.029), and impaired baseline EF (p=0.029) were associated with increased risk of cardiotoxicity. Statin (OR: 0.22; 95% CI: 0.05 to 0.84, p=0.028) and antiplatelet agents (OR: 0.19; 95% CI: 0.03 to 1.01, p=0.051) were protective agents against cardiac toxicity. Conclusion Effective anti-cancer therapy may be accompanied by an increased risk of cardiotoxicity. In this study, a history of prior heart disease, dyslipidemia, low baseline ejection fraction, and the administration of multiple anticancer therapy agents was associated with cardiotoxicity. Proactive management strategies aimed at mitigating the potential cardiotoxic effects of anti-cancer therapies are crucial.

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.

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.

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.
