How is tumor lysis syndrome treated?

How is tumor lysis syndrome treated?

In general, treatment of TLS consists of intensive hydration, stimulation of diuresis, and, more specifically, in the use of allopurinol and rasburicase.

Can you survive tumor lysis syndrome?

Prognosis in tumor lysis syndrome depends on the underlying malignancy characteristics. In patients with a hematologic malignancy, the mortality rate for tumor lysis syndrome is approximately 15%. The reported mortality of tumor lysis syndrome in patients with solid malignancies is reported at 36%.

What is seen in tumor lysis syndrome?

Tumor lysis syndrome is characterized by high blood potassium (hyperkalemia), high blood phosphate (hyperphosphatemia), low blood calcium (hypocalcemia), high blood uric acid (hyperuricemia), and higher than normal levels of blood urea nitrogen (BUN) and other nitrogen-containing compounds (azotemia).

Is tumor lysis syndrome fatal?

The syndrome characterized by these metabolic derangements is known as tumor lysis syndrome (TLS). TLS can cause life-threatening conditions and even death unless appropriately and immediately treated.

Can you have tumor lysis without chemo?

Tumor lysis syndrome (TLS) presenting in absence of chemotherapy is a rare occurrence. One of the true oncological emergencies, it can lead to significant morbidity and mortality. TLS is a phenomena usually associated with tumor cell death after treatment.

Is tumor lysis syndrome an emergency?

Tumor lysis syndrome (TLS) is the most common oncologic emergency. It is caused by rapid tumor cell destruction and the resulting nucleic acid degradation during or days after initiation of cytotoxic therapy.

What are the complications of tumor lysis syndrome?

Potential complications of tumor lysis syndrome include uremia and oliguric renal failure due to tubule precipitation of uric acid, calcium phosphate, or hypoxanthine. Severe electrolyte disturbances, such as hyperkalemia and hypocalcemia, predispose patients to cardiac arrhythmia and seizures.

How can you prevent and manage tumor lysis syndrome?

The most important treatment for TLS is prevention. The mainstays of TLS prevention include aggressive hydration, control of hyperuricemia with allopurinol and rasburicase treatment, and close monitoring of electrolyte abnormalities.

How do you prevent tumor lysis syndrome?

Can you get TLS without chemo?

TLS can occur spontaneously (before cancer treatment) but is more common within a week of starting treatment. TLS is not limited to patients receiving traditional chemotherapy; it can also occur in patients receiving steroids, hormonal therapy, targeted therapy, or radiation therapy.

Why is tumor lysis syndrome an emergency?

Tumor Lysis Syndrome (TLS) is an oncologic emergency due to massive tumor cell lysis, characterized by metabolic abnormalities that can lead to renal failure, seizures, and dysrhythmia.
