Can tumor lysis syndrome occur spontaneously?

Can tumor lysis occur spontaneously?

Tumour lysis syndrome occurs most commonly following treatment of a malignancy; however, it can occur spontaneously and must be recognized early to start appropriate treatment.

Can tumor lysis syndrome happen 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.

When does tumor lysis syndrome occur?

Tumour lysis syndrome usually occurs at the start of chemotherapy when a large number of tumour cells are destroyed. It can occur within a few hours of treatment, but it is most often seen 48–72 hours (2–3 days) after treatment starts.

What is a spontaneous tumor?

Oncology A neoplasm that arises in a control animal/person that is not exposed to a known carcinogen or tumor-promoting factor–eg, ionizing radiation, HPV.

How do you prevent TLS?

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.

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.

What is Tumour lysis syndrome?

Tumor lysis syndrome (TLS) is a condition that occurs when a large number of cancer cells die within a short period, releasing their contents in to the blood.

What is Rasburicase?

Rasburicase injection is used to treat high levels of uric acid (a natural substance that builds up in the blood as tumors break down) in people with certain types of cancer who are being treated with chemotherapy medications. Rasburicase injection is in a class of medications called enzymes.

How do you treat TLS?

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

Why is there hyperphosphatemia in tumor lysis syndrome?

Hyperphosphatemia is another electrolyte imbalance associated with tumor lysis syndrome. The nucleic acid has a phosphate group, and the breakdown of the tumorous cell will lead to the release of a significant amount of phosphorus into the bloodstream. Most of the phosphorus is renally excreted.

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%.
