Description

One of the most severe conditions known as tumor lysis syndrome is characterized by various metabolic disruptions that happen in rapidly proliferating tumors. It is primarily linked to hematological cancers and causes a considerable amount of morbidity and mortality. This study sought to ascertain the prevalence of laboratory tumor lysis syndrome in patients with hematological malignancies, as well as the characteristics that predict this condition. One of the devastating conditions of many metabolic disruptions that arise in quickly dividing bulk cancer is known as Tumor Lysis Syndrome (TLS).

Metabolic disturbances include hyperkalemia, hyperphosphatemia, hyperuricemia, and hypocalcemia (which is related to hyperphosphatemia) are its defining characteristics. TLS often arises from the extensive killing of cancerous cells following the start of cytotoxic treatments. Malignancies with extremely aggressive cell proliferation and rapid cellular turnover prior to treatment are less likely to experience spontaneous TLS.

Potassium, phosphate, and nucleic acids that are contained within the cells are quickly released into the extracellular environment as a result of the tremendous cell death. Uric Acid (UA) is produced by further metabolizing nucleic acids. This surpasses the kidney's excretory capabilities, and the resulting biochemical alterations may show up as neurological, cardiac, or renal failure in a clinical setting.

Acute Kidney Damage (AKI) can result from hyperuricemia, the most prevalent metabolic disorder brought on by the nucleic acid leak from tumor cells, which can cause crystals to develop in the renal tubules. Heart problems brought on by hyperkalemia may result in multiple organ failure and even death. AKI and obstructive nephropathy can result from the precipitation of calcium phosphate in the kidney caused by hyperphosphatemia. The type of malignancy, tumor burden Lactate Dehydrogenase (LDH) level, White Blood Cell Counts (WBC), intensity of anticancer therapy, age, and the existence of preexisting conditions like renal insufficiency, level of hydration, UA, and creatinine level are some of the factors that influence the development of TLS.

TLS is most frequently linked to Hematopoietic Malignancies (HMs), which include acute leukemia, especially Burkitt's lymphoma/leukemia, Acute Lymphoblastic Leukemia (ALL), and Acute Myeloid Leukemia (AML), and Non-Hodgkin Lymphoma (NHL). HMs, in particular leukemia and lymphoma, frequently multiply and degrade quickly, resulting in a greater TLS rate than other cancer forms. The incidence of TLS varies significantly amongst individuals with HMs as well, contingent upon various factors such as patient demographics, diagnostic criteria, length of study, kind of malignancy, and others.

TLS can be categorized as clinical or laboratory TLS based on this definition. The hallmark of laboratory TLS is biochemical alterations that do not manifest clinically. Severe metabolic disturbances can occur in patients even in the absence of symptoms. The term clinical TLS refers to biochemical alterations that are accompanied by clinical symptoms and require immediate attention. Given the rising incidence of cancer and the development of treatment plans, it is critical to pay adequate attention to the metabolic issues that highly proliferative HMs present with. These issues can lead to AKI, cardiac dysrhythmia, seizures, and other clinical problems. These could lead to an increased risk of death, increased hospital stays, and higher costs. It is critical to identify patients at risk of getting TLS because it is a preventable illness that can develop quickly. Finding the pertinent variables that predict TLS is crucial for prophylaxis and other preventative actions. However, in resourceconstrained environments like Ethiopia, there is a dearth of information regarding the occurrence of Laboratory Tumor Lysis Syndrome (LTLS) and the characteristics that predict it in patients with HMs. The variance in TLS prophylaxis, the diagnostic definition of TLS, the variation in study duration and the stage of the disease at the time of diagnosis or presentation to the health facilities are some of the factors that may contribute to the variation in incidence for LTLS. Allopurinol, a hypouricemic medication, was only utilized in the trial for patients with ALL and AML in order to avoid UA production; it is ineffective in decreasing UA that has already formed. The hospital's present setup does not use recombinant urate oxidase, which is effective in converting UA into allantois, which is quickly eliminated by the kidneys and is advised for high-risk patients.
