  1. aHaematological adverse events included leukopenia, neutropenia, lymphopenia, febrile neutropenia, anaemia and thrombocytopenia. Gastrointestinal disorders comprised diarrhoea, mucositis, stomatitis, nausea and vomiting. Metabolism and nutrition disorders were indicated by appetite loss and fatigue. Skin and subcutaneous tissue disorders involved rash, desquamation, hyperpigmentation, hand-foot syndrome and alopecia. Hepatic disorders were characterised by elevated levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), bilirubin, hypoproteinaemia and hypoalbuminaemia. Renal disorders included increased creatinine and blood urea nitrogen (BUN) levels. Other adverse events included dysgeusia, peripheral sensory neuropathy, arrhythmias, allergic reaction and pneumonitis. Total adverse events were defined as the highest grade of the above categorised adverse events.
