Is cross reactivity low enough to try cisplatin as an alternative for patients who experience hypersensitivity reaction to carboplatin?  

A couple of preparatory comments. First, there is a reasonable review recently published about platinum sensitivity and management questions related to this (Makrilia et al., PMID 20886011). The second comment is that platinum sensitivity reactions can be quite severe, and are relatively rare with &...
