RISK ASSESSMENT The timing of carboplatin ST in relation to initial HSR is vital for risk stratification and subsequent desensitization.

FINAL COMMENTS Clinical assessment and risk stratification of HRS is crucial Skin testing may predict anaphylactic reactions to platinum-type drugs Similar clinical approach os immediate reactions (IgE and non-ige mediated) Importance in selection of patients amenable for desensitized Learn how to design and adapt a desensitization protocol Some patients may need special premedication protocols Desensitization procedures allow the reintroduction of chemotherapy agents in patients with previous HSR. From our experience, the majority of patients (426 97%) tolerated the procedure with only mild or no HSR. 13
