European Society of Cardiology quality indicators for the prevention and management of cancer therapy-related cardiovascular toxicity in cancer treatment.

AIMS: To develop quality indicators (QIs) for the evaluation of the prevention and management of cancer therapy-related cardiovascular toxicity. METHODS AND RESULTS: We followed the European Society of Cardiology (ESC) methodology for QI development which comprises (i) identifying the key domains of care for the prevention and management of cancer therapy-related cardiovascular toxicity in patients on cancer treatment, (ii) performing a systematic review of the literature to develop candidate QIs, and (iii) selecting of the final set of QIs using a modified Delphi process. Work was undertaken in parallel with the writing of the 2022 ESC Guidelines on Cardio-Oncology and in collaboration with the European Haematology Association, the European Society for Therapeutic Radiology and Oncology and the International Cardio-Oncology Society. In total, 5 main and 9 secondary QIs were selected across five domains of care: (i) Structural framework, (ii) Baseline cardiovascular risk assessment, (iii) Cancer therapy related cardiovascular toxicity, (iv) Predictors of outcomes, and (v) Monitoring of cardiovascular complications during cancer therapy. CONCLUSION: We present the ESC Cardio-Oncology QIs with their development process and provide an overview of the scientific rationale for their selection. These indicators are aimed at quantifying and improving the adherence to guideline-recommended clinical practice and improving patient outcomes.

The heart failure pandemic: The clinical and economic burden in Greece.

BACKGROUND: The objective of this study was to identify the epidemiological and clinical characteristics of heart failure (HF) patients in Greece as well as the economic burden and the distribution of costs for the management of the disease. METHODS: Eight Greek secondary and tertiary cardiology centres from different cities have participated in a prospective, observational survey, the ESC HF Pilot Survey. 307 patients with HF, 177 hospitalised and 130 outpatients, have been recruited and monitored for 12months. Clinical and epidemiological data, along with data on mortality, hospitalisations and health care resources used have been collected. The economic evaluation was conducted from the social security system perspective. RESULTS: The annual mortality rate was 24.3% for the hospitalised patients vs 7.7% for the outpatients (P<0.001) and the annual rehospitalisation rate was 42.9% vs 19.2% respectively (P<0.001). Kaplan-Meier analyses revealed that patients with kidney dysfunction, S3 gallop and higher NYHA class have a significantly worse survival. The mean annual economic burden of the social security system per HF patient was estimated at €4411±4764. About two thirds of this cost is due to in-patient care. CONCLUSIONS: Despite the progress in the management of the disease, about one in four hospitalised patients dies and four in ten are rehospitalised in less than one year. Moreover, the disease imposes a significant economic burden for the social security system and national economy. Their findings suggest that there is still need of more effective drug treatment and efficient disease management programs focused in the reduction of the hospital admissions.

Assessment and treatment of cardiac iron overload in thalassemia.

Cardiac disease remains the major cause of death in thalassemia major and iron overload is involved in heart failure development. Cardiac iron load and heart injury are evaluated by different means, among which CMR measurements remain the best method for estimation. In cases of heart iron overload, chelation treatment should be appropriately tailored in terms of intensification.

Alternative pharmacological interventions that limit myocardial infarction.

Despite current optimal treatment, the morbidity and mortality of coronary heart disease remain significant worldwide and open the way for the development of novel cardioprotective therapies. In the last two decades, a remarkable scientific effort has focused on the limitation of infarct size. Important input from experimental studies has led the way in this direction. However, clinical and preclinical results using various cardioprotective strategies to attenuate reperfusion injury have generally not been applicable for every day clinical practice. Protection of the ischemic myocardium is known to occur as a result of ischemic preconditioning (PC), in which repetitive brief periods of ischemia protect the heart from a subsequent prolong ischemic insult. Although PC is a powerful form of protection, it is of limited clinical application for obvious ethical and practical reasons. Another endogenous form of cardioprotection, similar to PC but applicable at the time of reperfusion, termed postconditioning (PostC), has been recently described. Short series of repetitive cycles of brief reperfusion and re-occlusion of the coronary artery applied at the onset of reperfusion, reduce the infarct size and coronary artery endothelial dysfunction. At present, pharmacological PC and PostC are possible alternative methods that may substitute pharmaceutical treatments the short ischemic insults. Adenosine, nicorandil and other agents have been already used as pharmacological mimetics of ischemic PC in multicenter trials. We summarize the recent research efforts on novel therapeutic strategies and on the design of new compounds, based on the accumulated knowledge of the ligands, receptors and intracellular signaling pathways of PC and PostC.

Comparison of docetaxel and docetaxel-irinotecan combination as second-line chemotherapy in advanced non-small-cell lung cancer: a randomized phase II trial.

BACKGROUND: The aim of this study was to evaluate whether docetaxel (taxotere) treatment with or without irinotecan improved patient outcomes with similar toxicity in recurrent non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients with recurrent platinum-refractory NSCLC with Eastern Cooperative Oncology Group performance status of 0-2 were randomized to either docetaxel 30 mg/m(2) and irinotecan 60 mg/m(2) (days 1 and 8) or docetaxel 75 mg/m(2) (day 1), both administered every 3 weeks. RESULTS: A total of 130 patients were randomized. The response rate (RR) (20% versus 14%), overall survival (6.5 months versus 6.4 months) and 1-year survival (37% versus 34%) were similar in the combination and docetaxel arms, respectively. The combination arm demonstrated a longer time to tumor progression (TTP) (5.6 versus 4.8 months; P=0.065). Grade 3-4 neutropenia and anemia were similar in the combination and docetaxel arms. Grades 3-4 non-hematological toxicity (except diarrhea) was mild and was similar in the two groups. Grade 3-4 thrombocytopenia (17% versus 6%; P=0.04) and diarrhea (12% versus 3%; P=0.05) occurred more frequently in the combination arm. CONCLUSIONS: The administration of irinotecan with docetaxel in platinum-refractory NSCLC prolonged TTP, but did not improve significantly RR, median survival or 1-year survival. Second-line docetaxel monotherapy offers significant and reproducible efficacy in platinum-refractory NSCLC.

Waldenström's macroglobulinemia developing in a patient with multiple sclerosis: coincidence or association?

Multiple sclerosis (MS) has been reported in association with haematological abnormalities, including monoclonal gammopathies. We present a 54-year-old male patient with a 30-year history of MS who was admitted to our hospital for investigation of anaemia and increased erythrocyte sedimentation rate. A monoclonal IgM protein was detected by serum protein immunofixation, while bone marrow biopsy indicated a 70% infiltration by small lymphoplasmacytoid cells, in the context of a lymphoplasmacytoid immunocytoma, findings compatible to the diagnosis of Waldenström's macroglobulinemia (WM). To our knowledge, this is the first report of WM in a patient with MS. Further to the coexistence of the two diseases observed in the case presented here, there is additional evidence suggesting that the association of MS with plasma cell dyscrasias may not be coincidental.

Gemcitabine and oxaliplatin (GEMOX) in patients with cisplatin-refractory germ cell tumors: a phase II study.

BACKGROUND: To investigate the efficacy and toxicity of the combination of gemcitabine and oxaliplatin (GEMOX) in patients with relapsed or cisplatin-refractory non-seminomatous germ cell tumors (NSGCT). PATIENTS AND METHODS: Twenty-nine patients with relapsed or cisplatin-refractory NSGCT were treated with gemcitabine 1000 mg/m2 on days 1 and 8 followed by oxaliplatin 130 mg/m2 on day 1 every 3 weeks for a maximum of six cycles. Twenty-four patients (83%) were considered refractory and five (17%) absolutely refractory to cisplatin. RESULTS: Twenty-eight patients were assessable for response. Overall, nine patients (32%) achieved a favourable response (complete response, four; partial response, five). One of the complete responders relapsed after 7 months and went into disease-free status lasting for 11+ months after resection of lung metastases. The rest of the complete responders are continuously disease-free at 14+, 19+ and 28+ months with the study regimen plus or minus surgery. One of the complete responders had absolutely cisplatin-refractory disease and another one presented with a late relapse. Toxicity was primarily hematological and generally manageable: 62% of patients experienced grade 3/4 neutropenia, 10% neutropenic fever and 41% grade 3/4 thrombocytopenia. Non-hematological toxicity consisted mainly of nausea/vomiting. Three patients (10%) developed grade 3 neurotoxicity and discontinued treatment. CONCLUSIONS: The combination of GEMOX is an active, moderately toxic and easily administered regimen in patients with relapsed or cisplatin-refractory NSGCT. The 14% long-term disease-free status accomplished in this heavily pretreated patient population is quite encouraging.

Oxaliplatin plus high-dose leucovorin and 5-fluorouracil in pretreated advanced breast cancer: a phase II study.

BACKGROUND: The purpose of this study was to evaluate the efficacy and toxicity of oxaliplatin plus 5-fluorouracil (5-FU) and leucovorin (LV) in patients with metastatic breast cancer (MBC) previously treated with anthracyclines and taxanes. PATIENTS AND METHODS: Fifty anthracycline- and taxane-pretreated MBC patients were treated with oxaliplatin 85 mg/m(2) as a 2-h infusion on day 1, LV 200 mg/m(2)/day as a 2-h infusion followed by bolus 5-FU 400 mg/m(2)/day and a 22-h infusion of 5-FU 600 mg/m(2)/day for 2 consecutive days. Treatment was repeated every 3 weeks. Patients were evaluated for response every two cycles. RESULTS: The median age was 51 years (range 34-75). Twenty patients (40%) had received three or more chemotherapeutic regimens, 64% had three or four metastatic sites and 78% had visceral metastases. All patients had prior exposure to anthracyclines and taxanes. Based on an intention-to-treat analysis, one patient (2%) achieved a complete response and 16 (32%) a partial response, for a 34% overall response rate. Twenty-one patients (42%) had stable disease and 12 (24%) progressive disease. The median time to tumor progression was 5.3 months (range 0.5-12.8) and the median overall survival was 12.3 months (range 0.5-19.2). Toxicity was mild to moderate. Grade 3/4 neutropenia and thrombocytopenia occurred in 32% and 18%, respectively. Febrile neutropenia was experienced by three patients (6%), who were successfully treated. Grade 3/4 neurotoxicity was reported in 14% of the patients and gradually declined after treatment discontinuation. Cycle delays were reported in 28% of patients and dose reductions in 26%. Alopecia, nausea-vomiting, diarrhea and mucositis were not significant. There were no treatment-related deaths. CONCLUSION: The combination of oxaliplatin plus 5-FU/LV seems to be an active regimen in patients with MBC and prior exposure to anthracyclines and taxanes with a good safety profile. The incidence of severe toxicity was quite low and the compliance of patients to the treatment was satisfactory. The results obtained with this regimen could be considered encouraging in this heavily pretreated group of breast cancer patients with a high incidence of visceral metastases.
