Dr Prasit Watanapa, dean and director of Mahidol University’s Siriraj Medical School, said the faculty aimed to “defeat” breast cancer completely for patients in the first stage, with a 100-per-cent survival rate.

For second-stage and third-stage patients, the survival rates should exceed 90 per cent and 80 per cent respectively, he added.

The dean was speaking at a press conference yesterday held at the hospital.

He said that like elsewhere in the world, breast cancer was most prevalent among women patients in Thailand, killing more than 10,000 people each year.

The doctor said Siriraj Hospital had successfully improved its techniques of treating the cancer to meet international standards.

Dr Pornchai Ochareonrat, chief of the hospital’s Department of Head, Neck and Breast Surgery, told yesterday’s press conference that Siriraj had achieved an average survival rate of 92.1 per cent for patients treated over five years, and 85.6 per cent for those treated over 10 years.

He described the achievement as “rather satisfactory”.

According to Pornchai, the United Kingdom achieved a survival rate of 89.6 per cent for five years of treatment and 79 per cent for 10 years.

“This shows that Siriraj Hospital’s success rate is comparable to international standards,” he added.

He also said that the average survival rate for breast cancer patients in wealthy countries was 80 per cent, compared to 60 per cent for middle-income countries, and 40 per cent for low-income countries.

The hospital conducted a study on 3,435 breast cancer patients treated at Siriraj Hospital between 2003 and 2011, Pornchai said, adding that the average age of the patients was 51, with 24 the youngest and 86 the oldest.
