Cancer treatment resumption in patients with new-generation drug-eluting stents.
Coronary Artery Disease
OBJECTIVE: Percutaneous coronary intervention (PCI) with new-generation drug-eluting stents (DESs) may provide survival benefits to the cancer population undergoing PCI by expediting cancer treatment due to improved safety profile. We aimed to assess the safety of starting or resuming cancer treatment within 6 months of DES placement. We also compared the impact of different DES types on the overall survival (OS) in cancer patients and to identify a safe threshold for dual antiplatelet therapy (DAPT) discontinuation.
METHODS: Cancer patients at our institution undergoing PCI with DES from December 2014 to June 2017 were included. Baseline demographics, DAPT duration, malignancy type, stage, and treatment were retrospectively analyzed. Univariate Cox regression was used to pinpoint baseline characteristics that correlated with OS. Survivorship was determined by Kaplan-Meier analysis, and the log-rank test was used to compare OS among DES types.
RESULTS: Seventy-five patients were included. Of these, 45 had biodegradable polymer DES (Synergy) and 30 patients had durable polymer DES (Resolute Integrity, Xience, Ion, or Promus). Mean duration of follow-up was 1367 ± 334 days. There were two minor bleeding complications. No statistically significant differences in OS were found among different stent brands. Discontinuation of aspirin, early P2Y12 inhibitor discontinuation, and advanced cancer were significantly associated with OS. DAPT discontinuation12 months (attributed to radiation-induced heart disease) and one myocardial infarction and death. Of patients who resumed or started cancer treatment (chemotherapy, radiation therapy, or surgery) after PCI, all but one did so within 6 months of PCI, and most of them as early as 2 weeks.
CONCLUSION: Patients may resume cancer treatmentmonths, but additional longitudinal studies are needed.
