Cardiovascular diseases among diffuse large B-cell lymphoma long-term survivors in Asia: a multistate model study.

ABSTRACT:

Background

We modeled the clinical course of a cohort of diffuse large B-cell lymphoma (DLBCL) patients with no prior cardiovascular diseases (CVDs) using a multistate modeling framework.

Patients and methods

Data on 2600 patients with DLBCL diagnosed between 2000 and 2018 and had received chemotherapy with or without radiotherapy were obtained from a population-wide electronic health database of Hong Kong. We used the Markov illness-death model to quantify the impact of doxorubicin and various risk factors (therapeutic exposure, demographic, comorbidities, cardiovascular risk factors, and lifestyle factors which included smoking) on the clinical course of DLBCL (transitions into incident CVD, lymphoma death, and other causes of death).

Results

A total of 613 (23.6%) and 230 (8.8%) of 2600 subjects died of lymphoma and developed incident CVD, respectively. Median follow-up was 7.0 years (interquartile range 3.8-10.8 years). Older ages [hazard ratio (HR) for >75 versus ≤60 years 1.88; 95% confidence interval (CI) 1.25-2.82 and HR for 61-75 versus ≤60 years 1.60; 95% CI 1.12-2.30], hypertension (HR 4.92; 95% CI 2.61-9.26), diabetes (HR 1.43; 95% CI 1.09-1.87), and baseline use of aspirin (HR 5.30; 95% CI 3.93-7.16) were associated with an increased risk of incident CVD. In a subgroup of anticipated higher-risk patients (aged 61-75 years, smoked, had diabetes, and received doxorubicin), we found that they remained on average 7.9 (95% CI 7.2-8.8) years in the DLBCL state and 0.1 (95% CI 0.0-0.4) years in the CVD state, if they could be followed up for 10 years. The brief time in the CVD state is consistent with the high chance of death in patients who developed CVD. Other causes of death have overtaken DLBCL-related death after about 5 years.

Conclusions

In this Asian population-based cohort, we found that incident CVDs can occur soon after DLBCL treatment and continued to occur throughout survivorship. Clinicians are advised to balance the risks and benefits of treatment choices to minimize the risk of CVD.

Project description:Cardiotoxicity represents the most frequent cause with higher morbidity and mortality among long-term sequelae affecting classical Hodgkin lymphoma (cHL) and diffuse large B-cell lymphoma (DLBCL) patients. The multidisciplinary team of Fondazione Italiana Linfomi (FIL) researchers, with the methodological guide of Istituto di Ricerche Farmacologiche "Mario Negri", conducted a systematic review of the literature (PubMed, EMBASE, Cochrane database) according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, in order to analyze the following aspects of cHL and DLBCL survivorship: (i) incidence of cardiovascular disease (CVD); (ii) risk of long-term CVD with the use of less cardiotoxic therapies (reduced-field radiotherapy and liposomal doxorubicin); and (iii) preferable cardiovascular monitoring for left ventricular (LV) dysfunction, coronary heart disease (CHD) and valvular disease (VHD). After the screening of 659 abstracts and related 113 full-text papers, 23 publications were eligible for data extraction and included in the final sample. There was an increased risk for CVD in cHL survivors of 3.6 for myocardial infarction and 4.9 for congestive heart failure (CHF) in comparison to the general population; the risk increased over the years of follow-up. In addition, DLBCL patients presented a 29% increased risk for CHF. New radiotherapy techniques suggested reduced risk of late CVD, but only dosimetric studies were available. The optimal monitoring of LV function by 2D-STE echocardiography should be structured according to individual CV risk, mainly considering as risk factors a cumulative doxorubicine dose >250 mg per square meter (m2) and mediastinal radiotherapy >30 Gy, age at treatment <25 years and age at evaluation >60 years, evaluating LV ejection fraction, global longitudinal strain, and global circumferential strain. The evaluation for asymptomatic CHD should be offered starting from the 10th year after mediastinal RT, considering ECG, stress echo, or coronary artery calcium (CAC) score. Given the suggested increased risks of cardiovascular outcomes in lymphoma survivors compared to the general population, tailored screening and prevention programs may be warranted to offset the future burden of disease.
