Of the 366 patients included in the study, 178 were randomly assigned to chemoradiotherapy followed by surgery while 188 had surgery alone.
Median overall survival for the patients in the chemoradiotherapy–surgery group was 49.4 months, more than double the 24.0 month survival for the surgery group.
The research was led by Dr. Ate van der Gaast at the department of medical onocology at Erasmus University Hospital in Rotterdam, Netherlands.
