o Cardiotoxicity is a rare, but often lethal complication following HSCT.
o Cardiac events may occur early after HSCT or in the long term, mainly due to sepsis or chemotherapy toxicity
Shinya Ishida, et al. Ann Hematol 2016
Cardiovascular events after HSCT
o Cardiovascular diseases (CVD) after HSCT include cardiomyopathy, congestive heart failure, valvular dysfunction, arrhythmia, pericarditis, and coronary artery disease.
o CVD cumulative incidence is 5% to 10% at ten years after HSCT, accounting for 2% to 11% of mortality among long-term survivors.

o Compared to the general population, HSCT recipients experience increased cardiovascular death.
o Incidence rate difference = 3.6 per 1000 person-years (95% CI:1.7-5.5)

Time (years)
Cyclophosphamide-induced cardiotoxicity
o Cyclophosphamide (Cy)-induced cardiotoxicity, in particular, develops within the first 2–10 days after its first administration.
o The minimum dose for cardiac toxicity is still not known, although there are few reports of Cy toxicity at less than 100 mg/kg.
o Cy-induced cardiac toxicity seems correlated with the Cy total dose

Mechanism of Cy-induced cardiotoxicity
Cy metabolites can cause oxidative stress and endothelial capillary damage, with extravasation of toxic metabolites that result in myocytedamage.

Haplo
Cy-induced cardiotoxicity in haplo ?
o High dose Cy in HSCT conditioning regimen: Cy-induced cardiomyopathy has been reported among 1.5–17% of patients by single center studies, depending on the regimen and the patient population.
o PT-Cy in the Haploidentical HSCT setting is now widely used but risk factors, clinical manifestations and incidence of early cardiac event (ECE) are still poorly assessed.

SFGM-TC study
Unpublished data
Saint Antoine Studyo We aimed to compare the clinical outcomes between patients who
received PT-Cy and patients who did not, focusing on early cardiac events (ECE).
o ECE = cardiac event occurring between days 0 to +100.
o All consecutive patients undergoing HSCT in Saint Antoine Hospital between January 2013 and June 2018 were included, except cord blood recipients.
o Transthoracic echocardiography and ECG were performed systematically in all patients before HSCT, at day + 90, in case of clinical manifestation of an ECE.

o History of pre-transplant cardiac event was significantly associated with higher NRM and lower OS, PFS and GRFS in multivariate analysis.
o Cardiovascular risk factors and the cumulative doses of anthracycline were not significantly associated with the incidence of ECE.

o ECE resolved in 38/49 patients (78%) o 11 patients (22%) died without recovering from ECE within 4 months after transplanto ECE was associated with decreased OS (landmark analysis on day+100)
Outcomes
p=0.0154
o Early cardiac events (ECE) occurred more frequently (21% of patients)after HSCT with PT-Cy than after HSCT without PT-Cy (8% of patients)
o ECE may resolve in the majority of patients (78%)
o Patients who developed a cardiac event after transplantation have decreased OS (71% without ECE vs. 44% after ECE)
oThese results may help better selecting patients who are eligible to receive HSCT with PT-Cy, especially elderly ones, and those with a history of cardiac events.
Conclusions
o Better select patients who are eligible to receive HSCT with PT-Cy ?
o Patients without cardiovascular disease risk factors may develop cardiac events: close cardiac monitoring is warranted for all patients
o To prevent oxydative stress ?? (N-Acetylcysteine, Selenium)
o To reduce PT-Cy dose ? (GVHD?)
