Non-pegylated liposomal doxorubicin in older adjuvant early breast cancer patients: cardiac safety analysis and final results of the COLTONE study.

AIMS: To explore the cardiac safety of adjuvant Non-Pegylated Liposomal Doxorubicin (NPL-DOX) plus Cyclophosphamide (CTX) followed by weekly Paclitaxel, in elderly women (≥ 65 years) with high-risk breast cancer. Previously, we described no symptomatic cardiac events within the first 12 months from starting treatment. We now reported the updated results after a median follow-up 76 months. METHODS: The cardiac activity was evaluated with left ventricular ejection fraction (LVEF) echocardiograms assessments, before starting chemotherapy and every 6 months, until 30 months from baseline, then yearly for at least 5 years. RESULTS: Forty-seven women were recruited by two Units of Medical Oncology (Ethics Committee authorization CESM-AOUP, 3203/2011; EudraCT identification number: 2010-024067-41, for Pisa and Pontedera Hospitals). An episode of grade 3 CHF (NCI-CTCAE, version 3.0) occurred after 18 months the beginning of chemotherapy. The echocardiograms assessments were performed comparing the LVEF values of each patient evaluated at fixed period of time, compared to baseline. We observed a slight changed in terms of mean values at 48, 60, 72 and 84 months. At these time points, a statistically significant reduction of - 3.2%, - 4.6%, - 6.4% and - 7.1%, respectively, was observed. However, LVEF remained above 50% without translation in any relevant clinical signs. No other cardiac significant episodes were reported. To this analysis, in 13 patients (28%) occurred disease relapse and,  of them, 11 (23%) died due to metastatic disease. Eight patients died of cancer-unrelated causes. CONCLUSIONS: The combination including NPL-DOX in elderly patients revealed low rate of cardiac toxic effects. Comparative trials are encouraged.

Constrictive epicarditis: turtle cage or waffle operation?

A 72-year-old man, presenting with signs of pericarditis, was found at operation to have constrictive epicarditis. Operation consisted of pericardiectomy and creation of multiple longitudinal and transverse incisions of the epicardium.

[Appropriateness of prescription of exercise stress test, echocardiography, Holter monitoring and vascular echography]. / L'appropriatezza dei test cardiologici non invasivi. studio osservazionale sull'appropriatezza della prescrizione del test da sforzo, dell'ecocardiogramma, dell'ECG dinamico e dell'ecografia vascolare.

BACKGROUND: The aim of this study was to evaluate the appropriateness of prescription of non-invasive cardiological tests (exercise stress test, echocardiography, Holter monitoring and vascular echography), consecutively performed in our outpatient laboratory during 4 weeks. METHODS: We collected the following data: the appropriateness of prescription (according to the Italian Federation of Cardiology guidelines); test indications; the prescribing physician (cardiologist/non-cardiologist); type of prescription (elective/urgent); clinical utility (useful/useless) and result (normal/abnormal) of each test. RESULTS: We evaluated 960 prescriptions (320 exercise tests; 282 echocardiograms; 158 Holter tests; 200 vascular echographies). Test indications were appropriate (class I) in 37%, doubtfully appropriate (class II) in 39% and inappropriate (class III) in 24% of the cases. The appropriateness was slightly better for vascular echography and echocardiography (class I: 44% and 43%, respectively), markedly worse for exercise test (class I: 27%). The tests were considered useful in 46% and abnormal in 39% of the cases. Cardiologist-prescribed exams resulted more often appropriate (class I: 53 vs 30%; class II: 41 vs 38%; class III: 6 vs. 32%; p = 0.0001), more often useful (74 vs. 34%; p = 0.0001) and more frequently abnormal (43 vs. 37%; p = 0.05), when compared to non-cardiologist-prescribed exams. No differences in appropriateness, utility and test result have been detected between elective and urgent exams. Exercise test, echocardiogram and Holter monitoring resulted more often appropriate and useful when prescribed by cardiologists. CONCLUSIONS: This study confirms that only one third of prescriptions for non-invasive cardiological tests are appropriate. Cardiologist-prescribed exams are more often appropriate, useful and abnormal.

[Acute antineoplastic drug cardiotoxicity: a case report of life-threatening left ventricular failure associated with severe hyperglycemia]. / Cardiotossicità acuta da antineoplastici: descrizione di un caso di grave insufficienza ventricolare sinistra associata a severa iperglicemia.

Anthracyclines represent an established therapy for various hemopoietic and solid tumors; however the cardiotoxicity of these agents continues to limit their therapeutic potential in many cancer patients. Acute life-threatening cardiac toxicity which occurs immediately after a single dose of therapy is very rare under current treatment protocols. This form of toxicity occurs unexpectedly owing to a large variation in individual sensitivity. It may cause transient arrhythmias, hypotension, a pericarditis-myocarditis syndrome, or acute left ventricular failure. We report the case of a 43-year-old woman recently operated on for breast cancer, with acute life-threatening left ventricular failure associated with severe hyperglycemia, occurring a few hours after the first dose of anthracyclines for adjuvant chemotherapy. Severe regional wall motion abnormalities and a significant impaired systolic left ventricular function associated with high creatine phosphokinase-MB and troponin levels were observed. At discharge the regular insulin treatment was interrupted since glycemia was normalized, and complete recovery of the cardiac function was observed 1 month later. Differential diagnosis and the underlying pathogenetic mechanisms are discussed. This life-threatening event is rare, but considering the widespread use of anthracyclines in cancer treatment, it is important for the cardiologist to be aware of the potential acute cardiac toxicity of these agents for early diagnosis and management.

[Feasibility and accuracy of a rapid evaluation of the abdominal aorta during routine transthoracic echocardiography]. / Fattibilità ed accuratezza di una rapida valutazione dell'aorta addominale durante l'esame ecocardiografico transtoracico.

BACKGROUND: Mass screening for occult abdominal aortic aneurysm is not realistic for the low prevalence of this condition in the general population. Screening in a high-risk population, especially during standard echocardiographic examination, could be more cost-effective than a separate screening program. The aim of this study was to evaluate the feasibility and accuracy of a rapid evaluation (examination arbitrary time-limit of 2 min) of the abdominal aorta at the end of a routine transthoracic echocardiographic examination. METHODS: One hundred and eighty-one male patients (average age 61 years, range 45-79 years) were studied. A subgroup of 83 patients was also blindly examined by a radiologist for diagnostic accuracy evaluation. RESULTS: Abdominal aortic aneurysm was defined as an aortic diameter enlargement > or = 3.0 cm. Sixteen patients were excluded due to suboptimal aortic wall imaging or to examination lasting > 2 min (feasibility 91%). An occult aneurysm was found in 7 patients (3.8%). As regards the presence/absence of aneurysms in the subgroup of patients undergoing double examination, sensitivity and specificity were 80 and 100% respectively. CONCLUSIONS: Rapid evaluation of the abdominal aorta for aortic screening during routine echocardiography is highly feasible and accurate without any significant prolongation of the examination time and should therefore be routinely performed during standard examination.
