BACKGROUND Antiangiogenic agents(AAs)are increasingly used to treat malignant tumors and have been associated with gastrointestinal(GI)bleeding and perforation.Elective surgeries and endoscopy are recommended to be delayed for 31 d until after AAs treatment.Data regarding the safety of endoscopy while on antiangiogenic agents is extremely limited.No guidelines are in place to address the concern about withholding these anti-angiogenic drugs.AIM To evaluate the risks of endoscopy in patients on antiangiogenic agents from 2015 to 2020 at our institution.METHODS This is a single centered retrospective study approved by the institutional review board statement of the institution.Patients that underwent endoscopy within 28 d of antiangiogenic agents’treatment were included in the study.Primary outcome of interest was death,and secondary outcomes included perforation and GI bleeding.Data were analyzed utilizing descriptive statistics.Fifty-nine patients were included in the final analysis and a total of eighty-five procedures were performed that were characterized as low risk and high risk.RESULTS Among the 59 patients a total of 85 endoscopic procedures were performed with 24(28.2%)categorized as high-risk and 61(71.8%)procedures as low-risk.Of the total number of patients,(50%)were on bevacizumab and the rest were on imatinib(11.7%),lenvatinib(6.7%)and,ramucirumab(5%).The average duration between administration of AAs and the performance of endoscopic procedures was 9.9 d.No procedure-related adverse events were noted among our study population.We did observe two deaths with one patient,on lenvatinib for metastatic hepatocellular carcinoma,who had persistent bleeding despite esophageal variceal banding and died 4 d later from hemorrhagic shock.Another patient was diagnosed with acute myeloid leukemia died 24 d after an esophagogastroduodenoscopy with biopsy after transition to comfort care.CONCLUSION As per this single center retrospective study,the rate of endoscopic procedure-related adverse events and death within 28 d of AA administration appears to be low.
