Capecitabine-mediated heart failure in colorectal cancer: a case series.

ABSTRACT:

Background

Capecitabine is a pyrimidine antimetabolite that inhibits thymidylate synthase and is commonly used in the treatment of colorectal cancer. Adverse cardiac side effects are reported in 1-18% of patients receiving Capecitabine. The most commonly proposed mechanism of cardiotoxicity in the setting of Capecitabine use is vasospasm of the coronary arteries. However, cardiotoxicity can also present as an acute coronary syndrome, arrhythmia, hypertension, and/or sudden cardiac death. Profound non-vasospastic cardiotoxicity is rare.

Case summary

We describe two cases of acute heart failure leading to cardiogenic shock in patients shortly after exposure to Capecitabine. Both patients did not demonstrate the characteristic transient ST elevation seen in patients with coronary artery vasospasms secondary to Capecitabine. Both patients required admission to the Acute Cardiac Care Unit requiring vasopressor and inotropic support. Thorough diagnostic investigations including echocardiography, cardiac magnetic resonance imaging, and cardiac computed tomography did not identify infarction, myocarditis, or any infiltrative process to explain their symptoms. Both patients had complete resolution of cardiac function, with no long-term sequalae.

Discussion

In patients receiving Capecitabine, reversible heart failure leading to cardiogenic shock should be considered as a potential cardiotoxic side effect.

Project description:BackgroundCOVID-19 vaccines are important for patients with heart failure (HF) to prevent severe outcomes but the safety concerns could lead to vaccine hesitancy. This study aimed to investigate the safety of two COVID-19 vaccines, BNT162b2 and CoronaVac, in patients with HF.MethodsWe conducted a self-controlled case series analysis using the data from the Hong Kong Hospital Authority and the Department of Health. The primary outcome was hospitalization for HF and the secondary outcomes were major adverse cardiovascular events (MACE) and all hospitalization. We identified patients with a history of HF before February 23, 2021 and developed the outcome event between February 23, 2021 and March 31, 2022 in Hong Kong. Incidence rate ratios (IRR) were estimated using conditional Poisson regression to evaluate the risks following the first three doses of BNT162b2 or CoronaVac.FindingsWe identified 32,490 patients with HF, of which 3035 were vaccinated and had a hospitalization for HF during the observation period (BNT162b2 = 755; CoronaVac = 2280). There were no increased risks during the 0-13 days (IRR 0.64 [95% confidence interval 0.33-1.26]; 0.94 [0.50-1.78]; 0.82 [0.17-3.98]) and 14-27 days (0.73 [0.35-1.52]; 0.95 [0.49-1.84]; 0.60 [0.06-5.76]) after the first, second and third doses of BNT162b2. No increased risks were observed for CoronaVac during the 0-13 days (IRR 0.60 [0.41-0.88]; 0.71 [0.45-1.12]; 1.64 [0.40-6.77]) and 14-27 days (0.91 [0.63-1.32]; 0.79 [0.46-1.35]; 1.71 [0.44-6.62]) after the first, second and third doses. We also found no increased risk of MACE or all hospitalization after vaccination.InterpretationOur results showed no increased risk of hospitalization for HF, MACE or all hospitalization after receiving BNT162b2 or CoronaVac vaccines in patients with HF.FundingThe project was funded by a Research Grant from the Food and Health Bureau, The Government of the Hong Kong Special Administrative Region (Ref.

Project description:ImportanceUnregulated drug prices increase cancer therapy costs. After induction chemotherapy, patients with metastatic colon cancer can receive maintenance capecitabine and bevacizumab therapy based on improved progression-free survival, but whether this treatment's cost justifies its benefits has not been evaluated in the United States.ObjectiveThis study sought to determine the influence of capecitabine and bevacizumab drug prices on cost-effectiveness from a Medicare payer's perspective.Design, setting, and participantsThe incremental cost-effectiveness of capecitabine and bevacizumab maintenance therapy was determined with a Markov model using a quality-of-life penalty based on outcomes data from the CAIRO phase 3 randomized clinical trial (RCT), which included 558 adults in the Netherlands with unresectable metastatic colorectal cancer who had stable disease or better following induction chemotherapy. The outcomes were modeled using Markov chains to account for patients who had treatment complications or cancer progression. Transition probabilities between patient states were determined, and each state's costs were determined using US Medicare data on payments for capecitabine and bevacizumab treatment. Deterministic and probabilistic sensitivity analyses identified factors affecting cost-effectiveness.Main outcomes and measuresLife-years gained were adjusted using CAIRO3 RCT quality-of-life data to determine quality-adjusted life-years (QALYs). The primary end point was the incremental cost-effectiveness ratio, representing incremental costs per QALY gained using a capecitabine and bevacizumab maintenance regimen compared with observation alone.ResultsMarkov model estimated survival and complication outcomes closely matched those reported in the CAIRO3 RCT, which included 558 adults (n = 197 women, n = 361 men; median age, 64 and 63 years for patients in the observation and maintenance therapy groups, respectively) in the Netherlands with unresectable metastatic colorectal cancer who had stable disease or better following induction chemotherapy. Incremental costs for a 3-week maintenance chemotherapy cycle were $6601 per patient. After 29 model iterations corresponding to 60 months of follow-up, mean per-patient costs were $105 239 for maintenance therapy and $21.10 for observation. Mean QALYs accrued were 1.34 for maintenance therapy and 1.20 for observation. The incremental cost-effectiveness ratio favored maintenance treatment, at an incremental cost of $725 601 per QALY. The unadjusted ratio was $438 394 per life-year. Sensitivity analyses revealed that cost-effectiveness varied with changes in drug costs. To achieve an incremental cost-effectiveness ratio of less than $59 039 (median US household income) per unadjusted life-year would require capecitabine and bevacizumab drug costs to be reduced from $6173 (current cost) to $452 per 3-week chemotherapy cycle.Conclusions and relevanceAntineoplastic therapy is expensive for payers and society. The price of capecitabine and bevacizumab maintenance therapy would need to be reduced by 93% to make it cost-effective, a finding useful for policy decision making and payment negotiations.
