MUSICIAN Ricky Hayes died after a rare reaction to chemotherapy, an inquest heard.
Mr Hayes, who was well-known as the bassist for Portsmouth surfer punk band Emptifish, died last August, aged 47.
In May 2010, surgeons at Queen Alexandra Hospital, Cosham, discovered Mr Hayes had small bowel cancer, which had spread outside of his intestine.
The inquest heard that two months later he was put on a course of chemotherapy to stop the cancer recurring.
But the musician had an extremely rare enzyme deficiency called DPD deficiency, which could not break down the active ingredient of drug he was given.
Now his family of Mr Hayes is starting a campaign to make more people aware of the condition so they can get tested.
His partner Stephanie, 38, said: ‘We want to raise the awareness of DPD deficiency and that you can pay to get tested because even if it saves one more life it’s worth it.’
Pathologist Dr Barbara Borek said: ‘He (Ricky) had an enzyme deficiency.
‘He had been given treatment to prevent cancer coming back in the small bowel and had an adverse reaction.
‘He had a toxic reaction as a result of the chemotherapy that was given.’
After Mr Hayes started chemotherapy he began suffering from nausea, vomiting and numbness.
He was admitted to QA, where he was tested for the deficiency and was taken off the drug, but Mr Hayes died four weeks later.
It is not routine for doctors to carry out a test on the deficiency because it is so rare.
Coroner David Horseley said that Mr Hayes died as a result of a complication to the drug.
Mr Hayes is survived by his sons Elliot, 17, and James, 15, and a four-year-old daughter Alana, who live in Southsea.
