Cancer Med 2023; 12:21709-21724. [PMID: 38054208 PMCID: PMC10757145 DOI: 10.1002/cam4.6730] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2023] [Revised: 10/24/2023] [Accepted: 11/07/2023] [Indexed: 12/07/2023] Open
Abstract
OBJECTIVES To assess the occurrence of cardiotoxicity in patients with tumors receiving anthracycline-based chemotherapy, especially for sarcomas. METHODS This study summarized the types and frequency of adverse events (AEs) for three anthracyclines from the FDA adverse event reporting system (FAERS) database. FAERS data from January 2004 to June 2022 were collected and analyzed. Disproportionality analyses, logistic regression, and descriptive analysis were used to compare the differences in cardiac disorders. A retrospective cohort study was conducted in a single center between December 2008 and May 2022. Our hospital-treated patients with bone and soft tissue sarcomas (BSTSs) with anthracycline-containing chemotherapy were analyzed. Serum markers, echocardiography, and electrocardiography have been used to evaluate cardiotoxic events. RESULTS One hundred thousand and seventy-five AE reports were obtained for doxorubicin (ADM), epirubicin (EPI), and liposome doxorubicin (L-ADM) from the FAERS database. ADM (OR = 3.1, p < 0.001), EPI (OR = 1.5, p < 0.001), and sarcomas (OR = 1.8, p < 0.001) may increase the probability of cardiac disorders. Cardiac failure, cardiotoxicity, and cardiomyopathy were anthracyclines' top 3 frequent AEs. Among patients receiving ADM-containing therapy, those with ADM applied at doses ≥75 mg/m2 /cycle were more likely to develop cardiac disorders than the other subgroups (OR = 3.5, p < 0.001). Patients younger than 18 are more likely to benefit from dexrazoxane prevention of cardiac failure. Six hundred and eighty-three patients with BSTSs receiving anthracycline-based chemotherapy were analyzed in our center. Patients receiving ADM-containing chemotherapy were likelier to experience abnormalities in serum troponin-T and left ventricular ejection fraction (p < 0.05). 2.0% (6/300) of patients receiving ADM-containing chemotherapy required adjustment of the chemotherapy regimen because of cardiotoxicity, whereas none were in the EPI or L-ADM groups. CONCLUSIONS AND RELEVANCE Among patients receiving anthracycline-containing therapy, patients with BSTSs were more likely to develop cardiac disorders than other tumors. In addition, patients with BSTSs receiving ADM chemotherapy had a higher likelihood of cardiotoxic events than those receiving EPI or L-ADM.

Abstract
To assess the clinical effect of astragalus polysaccharide in preventing cardiotoxicity induced by chemotherapy of epirubicin. Two hundred forty-eight patients with breast cancer or malignant lymphoma were randomly divided into the experimental group (EG) (n = 124) and the control group (CG) (n = 124). The EG received chemotherapy regimen containing anthracycline epirubicin and astragalus injection, while CG received only chemotherapy regimen containing anthracycline epirubicin. We detected myocardial function (cardiac troponin I [cTnI], creatine kinase isoenzyme [CK-MB], left ventricular ejection fraction [LVEF], and the ratio of mitral annular diastolic peak velocity to atrial systolic velocity [E/A]) and incidences of cardiotoxicity to assess cardiac function, they were compared at before the first treatment course (T1), end of the second course (T2) and 6-month follow-up. We also detected proinflammatory cytokines (IL-6 and TNF-α), reactive oxygen species and antioxidant enzymes, glutathione peroxidase (GPx), and superoxide dismutase (SOD) aimed to discover potential mechanism. There were no statistical significances in differences of LVEF and E/A between 2 groups (P > .05) at T1 and T2, while levels of LVEF and E/A of EG were significant higher than those of the CG at 6 month follow-up, with statistically significant differences (P < .05). At T1, there were no statistical significances in differences of cTnI and CK-MB between 2 groups (P > .05); at T2 and 6 months follow-up, the cTnI, and CK-MB levels of EG was significantly lower than those of the CG, with statistically significant differences (P < .05). The incidence of cardiotoxicity of EG was 15% (17/113), which was significant lower than that of the CG (60%, 66/110), with statistically significant difference (P < .05). Moreover, the level of TNF-α, GPx, and SOD did not show significant difference (P > .05). The data in this pilot study suggested that astragalus polysaccharide may be an effective therapy for preventing cardiotoxicity induced by chemotherapy of epirubicin. Furthermore, larger, placebocontrolled, perspective studies are needed to assess the efficacy of astragalus injection treatment for preventing cardiotoxicity induced by chemotherapy of epirubicin.

Abstract
The breakthroughs of breast cancer management have led to a significant improvement in patient survival. However, to obtain this outcome a considerable price has been paid regarding cardiovascular side effects. Indeed, cardiovascular disease is the main cause of mortality in patients with breast cancer over fifty years of age, contributing more than cancer mortality in older cancer survivors. Thus, the identification and the management of patients with breast cancer at risk for cardiovascular events has become critical in order to reduce morbidity and mortality from cardiovascular toxicity due to cancer therapy, which may blunt its effectiveness. Today, cardioncology is a novel and recognized medical discipline, which aims to encourage a close interaction between cardiology and oncology, explore new strategies, collect evidence-based indications, and develop interdisciplinary expertise with the ultimate goal of minimize the risk of developing cardiovascular disease during and after anticancer therapy, prevent the breast cancer patient cured today from becoming the heart patient of tomorrow, and avoiding the possibility that pre-existent cardiac disease be a barrier leading to a reduction of a patient's therapeutic opportunities. In this review we discussed the advantages of a cardioncology approach in terms of risk stratification, monitoring for early diagnosis, prevention, and early treatment of cardiotoxicity.

Abstract
BACKGROUND Non-Hodgkin's lymphoma (NHL) survivors are at a higher risk of cardiovascular diseases (CVDs). METHODS A population-based study was conducted to investigate the cardiovascular mortality trends to identify NHL survivors at the highest risk. RESULTS The CVDs mortality was the second most common cause of death (13.07%) after NHL. There were more patients ≥ 60 years old in the cardiovascular group (87.2%), P < 0.001. Patients who died from CVDs had the best survival while patients who died from NHL had a significantly lower mean survival. The overall survival rate was 92.4%. Consistently, older age, unmarried, male patients, not recently diagnosed with NHL and not receiving radiation and/or surgery were associated with a worse survival across all models. The black race and stage IV only had a worse cardiovascular specific survival (CVSS). CONCLUSIONS Although the CVSS improved over time, the mortality from the CVDs is still the second most common cause of death after NHL. Older age, not married, black, male patients, not recently diagnosed with NHL, with an advanced stage and not receiving radiation and/or surgery were associated with a worse survival. Risk factor modification along with CVDs screening should be intensified in NHL patients with these mortality predictors.

Abstract
PURPOSE To investigate the cardiac safety of adjuvant Non-Pegylated Liposomal Doxorubicin (NPL-DOX) combined to Cyclophosphamide (CTX) and followed by weekly Paclitaxel, in older patients (≥65 years) with diagnosis of high risk breast cancer. The main end point of this prospective study was the detection of early episodes of symptomatic congestive heart failure (CHF). METHODS The cardiac function was evaluated by left ventricular ejection fraction (LVEF) measurements with repeated echocardiograms, performed 2 weeks before the beginning of chemotherapy and every 6 months, until 30 months after the study entry; then yearly for at least 5 years. RESULTS Forty-seven patients were enrolled from two Italian Divisions of Medical Oncology. Final results revealed no early episodes of symptomatic CHF within the first 12 months from the enrolment. Only two cardiac events were observed: an episode of atrial flutter after the first cycle of NPL-DOX and CTX, with a quick return to normal rhythm, and a grade 3 (scored to NCI-CTCAE, version 3.0) CHF episode, 18 months later chemotherapy start. No other relevant toxicities were reported. CONCLUSIONS This adjuvant combination including NPL-DOX in elderly patients, resulted in a low rate of cardiac toxic effects. Comparative trials should be encouraged to confirm these findings.

Abstract
Chemotherapy-induced cardiotoxicity (CIC) is a well-documented side effect of breast cancer treatment. Nearly all chemotherapeutic agents can cause CIC with the highest occurrence found in anthracycline and trastuzumab use. Treatment- and patient-related risk factors contribute to the development of CIC making risk modification an important consideration during breast cancer treatment. Prevention and early detection of cardiotoxicity are key to minimizing permanent and devastating cardiac damage; therefore, early involvement of a cardiologist including periodic cardiac monitoring during and after chemotherapy exposure is recommended.

Abstract
PURPOSE Cardiotoxic side effects of anthracyclines limit their use as effective chemotherapeutics. One mechanistic model of anthracycline-induced cardiotoxicity is attributed to the generation of intracellular reactive oxygen species (ROS). However, this theory has been questioned because several cardioprotective strategies have included the use of antioxidants without significant clinical benefit. We sought to determine whether measurement of intracellular reactive oxygen species after anthracycline exposure in vivo and in vitro could provide a means for designing more effective antioxidant-based cardioprotective schemes. METHODS Intracellular levels of ROS were assessed in peripheral blood mononuclear cells from leukemia bearing mice exposed to anthracyclines and in patients receiving anthracyclines. Comparison of cell death induction and ROS levels were also conducted in vitro in cardiomyocyte and leukemia lines. ROS blockade using antioxidants was conducted, and effects on cell death were assessed. RESULTS Elevated ROS in blood of mice and representative patient samples correlated with cardiomyocyte necrosis and decreased ejection fraction. In vitro, comparison of the cytotoxic effects of anthracyclines in acute leukemia cells and in cardiomyocytes revealed distinct kinetics of cell death induction and dependence upon oxidative stress. Although apoptotic cell death was observed in both acute leukemia cells and cardiomyocytes, the antioxidant N-acetylcysteine protected cardiomyocytes but not acute leukemia cells from anthracycline cytotoxicity. CONCLUSIONS Our findings point toward revisiting the use of NAC as a cardioprotective agent since it does not appear to interfere with the cytotoxic action of anthracyclines. NAC has been evaluated clinically for cardioprotective activity but future trials must ensure that adequate dose, scheduling and incorporation of markers of oxidative stress are included.

Abstract
BACKGROUND Over the past decades, survival of patients with Hodgkin lymphoma (HL) has increased but remains curtailed by cardiovascular mortality (CVM). HL survivors at greatest risk for cardiovascular death have not been clearly identified. We sought to report trends of CVM identify HL survivors at highest risk. METHODS The Surveillance, Epidemiology, and End Results (SEER) database was queried for all adult patients diagnosed with HL (age 20-49 years) between 1990 and 2011. The trend of CVM and disparities are presented. RESULTS Of 19,781 HL patients, 53% were male and 83% were white; patients had a mean age of 33 ± 8.3 years at diagnosis. Eighteen percent had stage I disease, 45% stage II, 18% stage III, and 15% stage IV. The risk for CVM was higher in blacks (adjusted hazard ratio [HR], 1.97; P = .002), men (adjusted HR, 2.2; P < .001), and patients with older age at diagnosis (adjusted HR, 1.073 per year; P < .001). CVM has decreased, with 5-year cumulative incidence decreasing from 1.17% in 1990 to 0.18% in 2006, averaging 7% per year (adjusted HR, 0.927; P < .001). This trend was seen only in patients with early disease (P < .001) but not with advanced disease (P = NS). CVM as a proportion of all-cause mortality increases sharply at 50 years of age, constituting more than 30% of all causes of death. CONCLUSION Despite an overall decrease in CVM in HL survivors over the last decades, older patients, black patients, and men, especially those who have advanced-stage disease at diagnosis, are at the highest risk of cardiovascular death. Cardiovascular screening and risk modification should be intensified in HL patients with these characteristics.

Abstract
PURPOSE Chemotherapy regimens containing anthracyclines and taxanes represent the landmark of neoadjuvant systemic therapy of breast cancer. In advanced breast cancer patients liposomal anthracyclines (LA) have shown similar efficacy and less cardiac toxicity when compared to conventional anthracyclines. We performed this retrospective analysis in order to evaluate the efficacy and tolerability of neoadjuvant regimens including LA outside of clinical trials in routine clinical practice. METHODS Fifty operable or locally advanced, HER2 negative, breast cancer patients were retrospectively identified in 5 Italian cancer centres. Nineteen patients had received 4 cycles of non-pegylated liposomal doxorubicin (NPLD) and cyclophosphamide, followed by 4 cycles of docetaxel, every 3 weeks. In 25 patients the reverse sequence was employed, and a third subgroup of 6 patients received 4 cycles of NPLD/cyclophosphamide every 3 weeks followed by 4 cycles of weekly carboplatin and paclitaxel. RESULTS We observed 10 pathological complete responses (pCR) (20.0%, 95%CI, 9% to 31%), and 35 (70%, 95%CI, 57.3% to 82.7%) partial responses (pPR), whereas no patients progressed onto therapy. In the small subset of triple negative tumors the pCR rate was 37.5%, and in tumors expressing ER and/or PgR it was 16.7%. A pCR rate of 26.5% was observed in tumors with high Ki-67, whereas in tumors with low Ki-67 only one (6.2%) pCR was observed (p=0.14). Treatments were well tolerated. The most common toxicities were myelosuppression and palmar-plantar erytrodysesthesia; 4 asymptomatic and transient LVEF decrease have been recorded, without any case of clinical cardiotoxicity. CONCLUSIONS NPLD-cyclophosphamide and taxanes sequential regimens were proven effective and well tolerated in breast cancer patients with contra-indication to conventional anthracyclines undergoing neoadjuvant chemotherapy, even outside of clinical trials in everyday clinical practice.

Abstract
The management of individual patients requiring anthracyclines remains challenging because uncertainty persists on predictors of cardiotoxicity. We aimed to perform a systematic review and meta-analysis on incidence and predictors of anthracycline chemotherapy in patients with cancer. Databases were searched for pertinent studies. Meta-analytic pooling with random-effects methods was performed for incidence estimates, while relying on descriptive statistics for prevalence and strength of association of predictors. From 16,054 retrieved citations, 18 studies reporting on 49,017 patients with cancer were included, with 22,815 treated with anthracyclines. After a median follow-up of 9 years, clinically overt cardiotoxicity occurred in 6% (95% confidence interval 3% to 9%), whereas subclinical cardiotoxicity developed in 18% (95% confidence interval 12% to 24%). Appraisal of independent risk factors of cardiotoxicity showed that cumulative anthracycline dose was most consistently reported as an accurate and robust predictor of cardiotoxicity, with an acceptable prognostic role also for chest radiotherapy, African-American ethnicity, very young or very old age, diabetes, hypertension, very high or very low body weight, or severe co-morbidities. In conclusion, despite ongoing refinements in chemotherapy regimens, anthracyclines still pose a significant risk of cardiotoxicity, especially in those requiring a high cumulative dose or chest radiotherapy.

Temporal changes in standard and tissue Doppler imaging echocardiographic parameters after anthracycline chemotherapy in women with breast cancer. Am J Cardiol 2013; 112:1005-12. [PMID: 23768465 DOI: 10.1016/j.amjcard.2013.05.038] [Citation(s) in RCA: 21] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2013] [Revised: 05/14/2013] [Accepted: 05/14/2013] [Indexed: 02/05/2023]
Abstract
Anthracyclines are established cardiotoxic agents; however, the exact extent and time course of such cardiotoxicity has not been appraised in detail. We aimed to exploit serial measurements of standard and tissue Doppler imaging (TDI) echocardiographic parameters collected in a prospective clinical trial to clarify the outlook of cardiac function during and long after anthracycline chemotherapy. Women enrolled in a randomized trial focusing on liposomal doxorubicin-based chemotherapy for breast cancer and providing ≥4 separate echocardiographic assessments were included. Repeat-measure nonparametric analyses were used to appraise changes over time in the standard and tissue Doppler imaging echocardiographic parameters. A total of 39 patients with serial imaging evaluations were enrolled. Significant temporal changes were found for the left ventricular ejection fraction and diastolic parameters, despite different temporal trends. Specifically, the left ventricular ejection fraction exhibited a V-shaped trend, decreasing initially from 63% to 61% but then recovering to 64% (p <0.001), with a similar trend in the TDI E/Em ratio (p = 0.011). In contrast, persistent impairments typical of an L-shaped trend were found for the E wave (p = 0.006), TDI lateral Em wave (p = 0.001), and TDI septal Em wave (p = 0.001). In conclusion, subclinical temporal changes in the standard and TDI echocardiographic parameters after anthracycline chemotherapy showed a distinctive pattern of transient impairment followed by full recovery of the left ventricular ejection fraction versus a persistent impairment of the diastolic parameters, which must be taken into account in the everyday treatment of such patients.
