If cetuximab is administered simultaneously, an overlap of radiation and cetuximab induced skin reactions is seen in the radiation field which may lead to very severe skin toxicity [ 22, 23].
This drug had proved to have very serious toxicity, first described in 1995, when multiple study subjects developed severe mitochondrial toxicity that led to fulminant hepatic failure and death.[23] These clinical trials used daily doses over the course of weeks that were thousands of times greater than the dose we used as a one-time injection of radiotracer.
This does not mean that toxicity prediction should be limited to frequent events, since very severe, although rare, toxicities may well justify the costs of genotyping.
Restriction of total ifosfamide dose to < 84 g/mwill reduce the frequency of, but not abolish, clinically significant nephrotoxicity, whilst doses > 119 g/mare associated with a very high risk of severe toxicity.
We first generated GalBD-LOVpep and GalAD-ePDZb1 fusions, but yeast expressing GalAD-ePDZb1 showed severe toxicity phenotypes (very poor growth and deformed cells).
Furthermore, current salvage chemotherapy after failure of first-line fluoropyrimidine-based chemotherapy has produced few and short-lived tumour responses, is effective in very limited patient populations, and causes severe toxicity.
They were assessed for severity [mild (Grade 1), moderate (Grade 2), severe (Grade 3), very severe (Grade 4)] using the Common Toxicity Criteria (CTC V3.0; National Institute of Health, Bethesda, MD).
Toxicity may become a very severe problem as we force patients down that route.
Though GCV liver toxicity has been reported to be very severe [ 20], it was mild and temporal in our study.
Haematological toxicity in the IPE arm, however, was very severe in spite of the G-CSF support with the grade 3 febrile neutropaenia noted in 31% of patients.
