SOUTHAMPTON hospital bosses have defended their treatment of a five-year-old brain tumour patient after his parents claimed he would “not have survived” under NHS care.

The five-year-old's family have told of his ''miracle'' recovery, as the centre where he was treated declared him cancer-free, it has been reported.

Ashya's mother Naghmeh, who alongside her husband Brett sparked an international manhunt last summer by removing the little boy from hospital in Southampton without medical consent, described the news as incredible.

''If we had left Ashya with the NHS in Britain, he would not be with us today. He was too weak and would not have survived,'' she told the paper.

But chiefs at University Hospital Southampton NHS Foundation Trust, which runs the hospital, said traditional radiotherapy and chemotherapy treatment carried almost exactly the same chance as survival as proton therapy. 

Ashya was finally allowed to undergo treatment at the Proton Therapy Centre (PTC) in Prague for brain cancer after a long legal battle fought by his parents.

Ashya's father Brett said his son's condition now justifies their actions in taking him from Southampton General Hospital last August, to Spain where they have a holiday home.

He said: ''We have saved his life'', adding that they would do the same thing again if they felt they had to.

A trust spokesman said Ashya had a 70-80 per cent chance of survival through conventional radiotherapy/chemotherapy – the same rate as quoted by the Prague proton therapy centre.

He added doctors had agreed to refer the family for proton treatment and the family were set to fund it.

The spokesman said: “The Trust considered there would be no benefit to Ashya of proton radiotherapy over standard radiotherapy and that view was supported by a national independent expert body.

“Despite this, the Trust agreed with the family to refer Ashya for proton radiotherapy, as the family had indicated that they could fund it privately.”

The High Court judgement that allowed the Kings to take Ashya to Prague also found that UHS “did not oppose” Ashya having proton beam treatment and “was not in a position to recommend or provide” said treatment.

The Kings were arrested in Spain and spent several nights in prison away from their son, before being released .

A High Court judge approved the move to take Ashya to Prague for proton therapy, which the PTC said is more effective than the radiotherapy Ashya was being offered on the NHS.

It limits the collateral damage of radiation to other vital organs, such as the heart and liver in Ashya's case. This would lead to less severe long-term side-effects including heart and breathing problems.

The therapy was not available for him on the NHS, although the health service later agreed to fund Ashya's treatment.

The family, who have previously spoken of their apprehension over returning to the UK for fear social services would get involved, are staying in Marbella where Ashya will continue his recovery.

The Sun quoted a report from the PTC which stated that the oncology department ''could speculate that Proton Therapy received could be sufficient to sterilise sites of possible future relapses of the tumour and chemotherapy could deteriorate the quality of life of Ashya''.
