Three people were found guilty Thursday of professional negligence resulting in the death of a 16-year-old high school student who had been given excessive doses of a cancer drug.

The Saitama District Court sentenced Ichiro Sumi, the girl's 33-year-old doctor, to two years in prison, suspended for three years. It slapped a fine of 300,000 yen on Toshio Honma, 37, who had been instructing Sumi at the time of the accident, and fined former Saitama Medical School professor Isuzu Kawabata, 67, 200,000 yen.

According to the court, Yuri Furudate, who was undergoing treatment for a tumor on her jaw at Saitama Medical Center, died Oct. 7, 2000, of multiple organ failure after receiving a week's worth of the cancer medicine every day after Sumi entered the wrong information on the girl's medical chart.

Presiding Judge Kaoru Kanayama said the social impact of the malpractice was grave, as doctors at a medical facility affiliated with a medical university had made such a dramatic error.

The girl's parents expressed outrage at the ruling, which they said treated human life too lightly.
