Difficulties in differential diagnosis of hematological toxicity during therapy with immune checkpoint inhibitors

Abstract

Checkpoint inhibitors have radically changed the approach to oncology and have become the new standard of treatment for many solid tumors, significantly increasing the life expectancy of patients. With the advent of a new class of drugs, we are faced with a completely recognized toxicity profile. The spectrum affects other manifestations that affect almost every organ and system of the body. Most often the skin, the secretion of the internal gland, the gastrointestinal tract, lungs, and liver are affected. Complications from the urinary, cardiovascular, muscular-articular, nervous and hematopoietic systems occur less frequently. This article will discuss one of the rare complications that occurs during therapy with checkpoint inhibitors — thrombocytopenia with hemorrhagic syndrome. The main purpose of the article is to increase clinical alertness and highlight the relevance of the problem of rare complications during immunotherapy.
