Background

++

Image not available. Tumour lysis syndrome (TLS) is a potentially lethal clinicopathological syndrome caused by rapid lysis of malignant cells. The consequent metabolic derangements give rise to a spectrum of symptoms, which are listed in Table 13.1. TLS may be present prior to treatment, due to high cell turnover, but more usually occurs 12-72 hours after initiation of therapy.

How may the risk of tumour lysis syndrome be gauged?

++

Factors influencing the risk of TLS may be grouped into disease, patient and treatment factors. Table 13.2 gives a guide to risk assessment for some more common situations in adult oncology, although each patient requires a personalized assessment of risk.
