The puzzling clinical presentation of fluoropyrimidines cardiotoxicity.

The cardiotoxicity of fluoropyrimidines (FP) [5-Fluorouracil and Capecitabine] is often reported as acute cardiac ischemia with rest typical angina, signs of ischemia at electrocardiogram (ECG), and ventricular kinetics abnormalities. However, silent ischemia, effort-related toxicity, and ventricular arrhythmias (VA) have been also described. The aim of this study is to report a consecutive series of 115 patients with FP cardiotoxicity observed in a single center both within clinical prospective studies and during the clinical routine.

Cardiotoxicity from Capecitabine Chemotherapy: Prospective Study of Incidence at Rest and During Physical Exercise.

Background: Physical activity may increase the risk of cardiotoxicity (myocardial ischemia, major arrhythmias) of 5-Fluorouracil, but this risk has never been investigated for its prodrug capecitabine.

Patients And Methods: One hundred and ninety-two consecutive patients undergoing capecitabine chemotherapy from December 1, 2010 through July 31, 2016 were prospectively evaluated. The baseline evaluation included electrocardiography (ECG) and echocardiography (2DE); a follow-up evaluation, including ECG and exercise stress testing (2DE in case of ECG abnormalities), was done after ≥10 days of treatment.

Fluoropyrimidine-Associated Cardiotoxicity: Probably Not So Rare As It Seems.

This letter to the editor focuses on a recent report of a retrospective case‐control study of fluoropyrimidine‐associated cardiotoxicity in cancer patients.

Nonpegylated liposomal doxorubicin combination regimen in patients with diffuse large B-cell lymphoma and cardiac comorbidity. Results of the HEART01 phase II trial conducted by the Fondazione Italiana Linfomi.

The purpose of this phase 2, multicenter study was to determine the activity and safety of nonpegylated liposomal doxorubicin as part of "R-COMP" combination in patients with diffuse large B-cell lymphoma and coexisting cardiac disorders. The study was conducted using a Bayesian continuing assessment method using complete remission rate and rate of cardiac events as study endpoints. Between November 2009 and October 2011, 50 evaluable patients were enrolled (median age, 76 years).

Anthracycline-free neoadjuvant therapy induces pathological complete responses by exploiting immune proficiency in HER2+ breast cancer patients.

Background: Neoadjuvant Chemotherapy (NC) including trastuzumab induces a high rate of pathological Complete Responses (pCR) in patients with locally advanced HER2-overexpressing Breast Cancer (BC), but is penalized by a severe cardiotoxicity when combined with anthracyclines. A phase II study was designed to assess whether an anthracycline-free NC regimen based on the early addition of trastuzumab to paclitaxel may increase the pCR rate without inducing severe cardiotoxicity in patients with locally advanced HER2-overexpressing BC. Immunomonitoring was performed to assess the contribution of patients' immunological background to the induction of clinical responses.

Neoplastic pericardial disease in lung cancer: impact on outcomes of different treatment strategies. A multicenter study.

Background: Local (intrapericardial) chemotherapy has been reported to be useful for the treatment of neoplastic pericardial disease, but it has never been compared to systemic chemotherapy, a combination of the two and simple pericardial drainage or sclerosis.

Methods: We analyzed the clinical and echocardiographic data of 119 patients, suffering of neoplastic pericarditis due to lung cancer (97 with non-small-cell), comparing the outcomes of four different treatment strategies (extended catheter drainage/sclerosis, systemic chemotherapy, local chemotherapy, and combined - local plus systemic - chemotherapy) at the last available follow-up or at the change of therapy after a treatment failure. The outcomes (based on semiquantitative evaluation of pericardial disease) were classified as complete, partial, no response and progressing disease.

Capecitabine cardiac toxicity presenting as effort angina: a case report.

We report a case of capecitabine-induced cardiotoxicity (effort angina) in a woman with metastatic breast carcinoma. Due to cancer progression, rechallenge of therapy with capecitabine was attempted, using several strategies in order to prevent cardiotoxicity. The most (even if not fully) effective strategy was reducing capecitabine dosage together with nitrates, calcium-channel blockers and trimetazidine therapy.

Severe ventricular dysrhythmias and silent ischemia during infusion of the antimetabolite 5-fluorouracil and cis-platin.

The antimetabolite 5-fluorouracil is frequently used in the therapy of various malignancies. Cardiotoxicity has frequently been described during treatment, but there is no common agreement on the need to perform cardiovascular monitoring of patients during 5-fluorouracil administration. We report the case of a young patient with an head-neck cancer on whom a continuous electrocardiogram recording was performed, documenting serious ventricular dysrhythmias in the presence of myocardial ischemia during 5-fluorouracil and cis-platin infusion.

[Long QT and torsade de pointes in a patient with acquired human immunodeficiency virus infection in multitherapy with drugs affecting cytochrome P450].

In acquired human immunodeficiency virus (HIV) infection, a long depolarization period at ECG may be the consequence of cardiac complications due to viral myocarditis or cardiomyopathy or indirectly due to autonomic neuropathy, or sometimes resulting from pharmacological treatments. Several drugs administered for direct treatment of HIV disease or its complications, such as antiretrovirus, fluconazole, and antibiotics, may induce ventricular arrhythmias due to long QT prolonged depolarization period. Also methadone, frequently associated with HIV therapy to treat patients with opiate addiction, is described in the literature to have cardiac inotropic effects.
