SYDNEY:  The doctor responsible for giving dozens of chemotherapy patients incorrect drug dosages at St Vincent’s Hospital, Darlinghurst, has taken immediate leave and will never return to work.

Up to 70 cancer patients were given incorrect low doses of the chemotherapy drug carboplatin over a 3-year period, with five suffering recurrences of their disease.

Oncologist John GRYGIEL gave the low doses of carboplatin – about a half to one-third of the normal amounts – to neck and head patients.  The ABC exposed the scandal.

The hospital knew about the errors since at least August 2015 but failed to tell any patients for about six months.
