Another victim of SA Health's chemotherapy bungle in which cancer patients were under-dosed with the necessary drug has died.

Bronte Higham, 67, died early on Sunday morning at Daw House Hospice in Adelaide after relapsing with leukaemia earlier this year.

Mr Higham was one of 10 leukaemia patients who were incorrectly given one instead of two daily doses of a chemotherapy drug over a six-month period.

Five of the patients were at the Royal Adelaide Hospital and the other five at Flinders Medical Centre.

Mr Higham bravely fronted a parliamentary inquiry in May, describing himself as a "dead man walking".

"I don't know when I'm going to fall off the perch," he said at the time.

"I just don't want my family to have to go for years asking for compensation.

"The victims and the families deserve compensation for this because it's been one big stuff-up."

The emotional appeal forced the State Government to offer $100,000 compensation payments to those affected.

Fellow patient Andrew Knox expressed "extreme" and "overwhelming sadness" at the news of Mr Higham's death.

"Bronte was never given his best chance of survival," Mr Knox said.

"That sadness is tainted with anger from the fact that for the first 14 months after the error in his treatment, Bronte and his family were denied the support they both deserved and were sorely entitled to.

"It is only weeks since Bronte, despite having relapsed in April, so bravely fronted the parliamentary select committee with wife Ricki, son Kym and daughter Jodie, forcing the Premier to intervene."

At least two other affected patients are known to have since died.
