Kanser immünoterapisi sırasında gelişen inflamatuvar artrit olgusu

Günümüzde modern tıpta yaşanan teknolojik ve bilimsel gelişmeler solid ve hematolojik malignitelerin tedavisinde yeni tedavi stratejilerin ortaya çıkmasını sağlamıştır. Bu gelişmelerden biri de kanser immünoterapisi olarak adlandırılan ve ileri evre tümörlerin tedavisinde kullanılan İmmün Checkpoint İnhibitörleri’nin (İCİ) kullanımıdır. İCİ denen bu grup moleküller, kanser hücrelerinin T lenfosit başta olmak üzere doğal ve adaptif immünitenin efektör hücrelerinde bulunan koreseptörlerin aktivasyon veya inhibisiyonu ile bu hücreler tarafından öldürülmesini sağlayan monoklonal antikorlardır. Bununla birlikte kanser immünoterapisi, immünite hücreleri üzerindeki manüplasyonu nedeniyle self toleransı ortadan kaldırarak konağın sağlıklı hücrelerinin de hedef haline gelmesine ve bunlara karşı bir dizi immün reaksiyon başlamasına neden olabilmektedir. Biz de kanser immünoterapisi sırasında gelişen inflamatuvar artrit olgusunu sunmayı amaçladık.

Inflammatory arthritis during immune checkpoint inhibitors therapy: case report

Nowadays, technological and scientific developments in modern medicine have enabled the emergence of new treatment strategies in the treatment of solid and hematologic malignancies. One group of these developments is, also called cancer immunotheraphy, Immune Checkpoint Inhibitors (ICI) thatareused in laterstages of tumors. ICI’s are monoclonal antibodies that allow cancercells to be killed by natural and adaptive immunity, especially T lymphocytes via activation or inhibition of the co-receptors. However, cancer immunotherapy can lead to activation of the immunecells to host’s healthy cells by eliminating self-tolerance, and to start series of immune reactions. Here, we aimed to present a case of inflammatory arthritis during cancer immunotherapy.
