Adverse myocardial and vascular side effects of immune checkpoint inhibitors: a prospective multimodal cardiovascular assessment.

BACKGROUND: Immune checkpoint inhibitors (ICIs) can induce cardiovascular toxicities. OBJECTIVES: To prospectively assess the incidence of major cardiovascular events (MACE) on ICIs in solid cancer patients: myocarditis, pericarditis, acute coronary syndrome, heart failure, high-degree conduction abnormalities or sustained ventricular arrhythmias, or cardiovascular death at 6 weeks (early MACE), including asymptomatic clinical changes by an independent adjudication committee using current recommended diagnostic criteria. The secondary objective was the incidence of the above-mentioned events adding atrial fibrillation (AF) at 6 months (late MACE). RESULTS: Participants underwent pre-ICIs and repeated multimodality cardiac imaging (echocardiogram, cardiac magnetic resonance (CMR)), serum biomarkers (ultrasensitive troponin I), and rhythm surveillance (ambulatory ECG monitoring) at 6 weeks and 6 months. Forty-nine patients (38 (77.6%) male; mean age 64.3 (SD 11.0) years old) were included (June 2020-December 2021). Early MACE were observed in 9 (18.4%) patients at mean 40.1 (SD 5.9) days, with heart failure (HF) in 5 (10.2%), ventricular arrhythmias, or new conduction disorders in 4 (8.2%) patients. History of AF (HR 4.49 (CI 1.11-18.14), P = 0.035) predicted early MACE. At 6 months follow-up, 18 MACE were observed in 15/49 (31%) patients, with 6 (12.2%) HF events, 5 (10.2%) significant ventricular arrhythmias, or conduction disorders, and 4 (8.2%) AF. There was a significant decline in LVEF (P < 0.001) in patients with no MACE (P = 0.003) or HF (P = 0.0028). Higher creatinine at inclusion (HR 0.99 [0.98-1.00], P = 0.006) predicted HF on multivariate analysis. There were no significant T1 or T2 mapping changes in our study cohort on repeated CMR. CONCLUSIONS: Cardiotoxicity on ICIs is more frequent than previously described when using a thorough detection strategy, consisting mainly in HF and asymptomatic rhythm disorders.

Cabazitaxel schedules in metastatic castration-resistant prostate cancer: a review.

Cabazitaxel (25 mg/m2 every 3 weeks) is the standard second-line chemotherapy for patients with metastatic castration-resistant prostate cancer previously treated with docetaxel. It is associated with a risk of neutropenic complications, which may be a barrier to its use in daily clinical practice, particularly in frail elderly patients. Here the authors reviewed key studies conducted with cabazitaxel (TROPIC, PROSELICA, AFFINITY, CARD and the European compassionate use program) and pilot studies with adapted schedules. Based on this review, the use of prophylactic granulocyte colony-stimulating factor from cycle 1 appears crucial to maximize the benefit-risk ratio of cabazitaxel in metastatic castration-resistant prostate cancer. Preliminary data with alternative schedules look promising, especially for frail patients. Results of the ongoing Phase III CABASTY trial (ClinicalTrials.gov: NCT02961257) are awaited.

Assessment of Health-Related Quality of Life in Patients with Advanced Prostate Cancer-Current State and Future Perspectives.

With the therapeutic landscape of advanced prostate cancer rapidly evolving and oncological benefits being shown for a plethora of new agents and indications, health-related quality of life (HRQOL)-associated evidence is still subpar. In the current comprehensive review, we discuss the importance of HRQOL for patients with advanced PC (metastatic hormone-sensitive prostate cancer (mHSPC), metastatic castration-resistant prostate cancer (mCRPC) and non-metastatic castration-resistant prostate cancer (nmCRPC)), and present the most frequently used tools to evaluate HRQOL in recent randomized trials. Furthermore, we discuss the ease of use of these validated questionnaires for clinicians and try to focus on the suggested appropriate use in clinical practice, as well as potential strategies for improvement of HRQOL evaluation in these clinical scenarios of advanced prostate cancer.
