'Even on my deathbed I will never forgive him:' Bernie Madoff's sole surviving son is fighting for his life as he battles stage four cancer

Andrew Madoff, the 47-year-old son of imprisoned Ponzi schemer Bernard Madoff, is battling stage four cancer and says even on his deathbed, he won't forgive his father for bilking billions of dollars from his investors.

'It's hard. It's been a long road,' he told People Magazine . 'I've been receiving treatment since January, and it's a lot - six rounds of chemotherapy, then radiation, then more chemo before the transplant, then the transplant itself.'

The younger Madoff was diagnosed with stage one mantle cell lymphoma in 2003 and earlier this year, the cancer spread throughout his entire body.

He had a stem cell transplant on May 29 that is starting to show signs of failing, so he had a donor lymphocyte infusion on Tuesday to try and salvage the transplant, People reports.

'This will hopefully prevent it from failing,' he said. 'If they didn't do this, it would certainly have failed.'

Madoff's father has been sentenced to 150 years in federal prison for running a Ponzi scheme that robbed thousands of investors of roughly $65 billion.

Andrew and his brother Mark, who committed suicide in December 2010, had worked as traders in their father's investment company. Both brothers claimed to not have any knowledge of the massive fraud.

'Even on my deathbed I will never forgive him for what he did,' Andrew Madoff said.

Mantle cell lymphoma, which most often affects men over the age of 60, is a rare type of non-Hodgkin lymphoma that causes white blood cells to grow and multiply uncontrollably. It is aggressive and often comes back after patients go into remission.

Survival rates are generally poor compared to other types of non-Hodgkin lymphomas and most people do not live longer than five years after diagnosis.
