Meeting Highlights

ESMO World Congress on Gastrointestinal Cancer

Walter Alexander

This year’s 19th annual European Society for Medical Oncology (ESMO) World Congress on Gastrointestinal Cancer gathered more than 3,600 medical and scientific professionals in Barcelona, Spain, from June 23 to 28. The meeting brought particular attention to the influence of primary tumor sidedness in colorectal cancer as it affects prognosis and treatment outcomes to meet the growing interest in this theory.
