AN expert report found it was "miraculous" a cancer patient treated by Dr Paschal Carmody survived as long as he did.
Consultant cancer surgeon Colin Hopper, who compiled the report, also described the doctor on trial for deception charges as "a caring physician who was interested in doing good for his patients".
He told a court that Dr Carmody "believed overall he was doing patients good".
Mr Hopper was the final prosecution witness in the trial at Ennis Circuit Court.
He went to Dr Carmody's East Clinic, Killaloe, in 2003 to examine the cancer treatments on behalf of the authorities.
A report by Mr Hopper found it was "miraculous" that a cancer patient of Dr Carmody's was alive in 2003 and suggested "that at least some of these alternative treatments have had a beneficial effect".
Dr Carmody (62) of Ballycuggeran, Killaloe, denies defrauding relatives of two terminally ill cancer patients of €16,554 at the East Clinic in Killaloe in 2001-2002 concerning Photodynamic Therapy (PDT) treatment given to the two.
Seven charges relate to Co Wexford teenager Conor O'Sullivan, who died in November 2002. Two relate to John Sheridan (58) of Kells, Co Kilkenny, who died in November 2002.
The case continues today.
