Clinical Manifestations, Diagnosis, Treatment and Prognosis of Uveitis Induced by Anticancer Drugs: A Review of Literature.

Abstract

There are increasing reports that anticancer drugs, especially immunotherapy and specific targeted therapy, can cause uveitis, but it is not fully understood whether the clinical features of this drug-induced uveitis differ from those of other types of uveitis and whether there are differences between these drugs. We retrospectively reviewed the published cases and case series in PubMed, Embase, Web of Science, and Cochrane from January 2011 to October 2020. We analysed the data, including patients’ basic information, medications used, duration of use, time to onset, clinical manifestations, diagnosis, treatment, and prognosis of uveitis. We focused on the differences in uveitis caused by immunotherapy and specific targeted therapy. Altogether 93 cases (43 men, 48 women, and 2 cases whose gender was not mentioned) reported in 55 articles were included in this study. The average age was 59.6 ± 13.5 years. Eighty percent of the patients had bilateral involvement. Sixty cases were caused by immunotherapy (64.5%), and twenty-six were caused by specific targeted therapy (27.9%). No significant difference was found in the mean time from treatment to onset between the two groups. Anticancer drug-induced uveitis can involve all parts of the uvea from anterior to posterior, manifested as anterior chamber flare, anterior chamber cells, papillitis, macular oedema, subretinal fluid, and choroidal effusion. Anterior uveitis (24 cases, 40.0%) was more common in immunotherapy, and intermediate uveitis (8 cases, 30.8%) was more common in specific targeted therapy. The mean LogMAR visual acuity in specific targeted therapy at presentation was lower than in immunotherapy, but it was not statistically significant. Corticosteroid therapy can effectively control uveitis induced by anticancer drugs. However, the survival prognosis was poor. Among the 19 patients with reported cancer prognosis, seven (36.8%) had no cancer progression, eight (42.1%) had further metastases, and four (21.0%) died of cancer. In conclusion, uveitis caused by anticancer drugs involves both eyes and manifests as various types of uveitis. Patients with specific targeted therapy are more likely to have intermediate uveitis and low vision, and immunotherapy patients are more likely to have anterior uveitis. Corticosteroids are effective against uveitis caused by anticancer drugs.
