Objective: This systematic review aims to consolidate existing literature on the prevalence of oncological emergencies in patients with solid organ carcinomas following chemotherapy, providing insights into the epidemiology, clinical presentation, and management strategies. Methods: A comprehensive search was conducted across major electronic databases for studies published between 2010 and 2024. Relevant articles were screened based on predefined inclusion criteria, with data extracted and synthesized to assess the prevalence and characteristics of oncological emergencies in this population. Results: A total of 75 studies met the inclusion criteria, encompassing a diverse range of solid organ carcinomas and oncological emergencies. The prevalence of oncological emergencies varied across tumor types, with common presentations including neutropenic fever, tumor lysis syndrome, spinal cord compression, and sepsis. Factors such as tumor histology, stage, and treatment regimens were found to influence the incidence of these emergencies.
