Spontaneous Tumor Lysis Syndrome in Cancer Patients
Spontaneous tumor lysis syndrome (TLS) is a condition that occurs more frequently in individuals diagnosed with gastric, lung, or breast cancer, although it is less common in those with liver cancer. Unlike individuals with solid tumors, those with these specific types of cancer are at a higher risk of developing TLS. Interestingly, symptoms of spontaneous TLS may even manifest before a malignant disease is diagnosed by doctors. Oncologists often become aware of the condition when they observe significant electrolyte imbalances and kidney impairment in their patients.
Symptoms of Tumor Lysis Syndrome (TLS)
Tumor Lysis Syndrome (TLS) usually presents with subtle symptoms initially. Nausea, with or without vomiting, is a common early symptom. Individuals may also experience overall fatigue, a decreased appetite, restlessness, and increased irritability. Muscle twitches, spasms, and cramps may occur, along with reports of numbness or tingling sensations. Pain in the flank area, which includes the upper abdomen, back, and sides, can develop. Confusion, seizures, and hallucinations are possible symptoms as well. Kidney problems may lead to dark urine or decreased urine output. Additionally, a rapid, fluttering, or pounding heartbeat, known as heart palpitations, is often reported. If left untreated, the symptoms of TLS will worsen as the levels of chemicals in the bloodstream continue to rise.
