Adding the chemotherapy docetaxel to active symptom control in advanced esophagogastric adenocarcinoma improves survival of patients. These are the results of the phase III COUGAR-02 trial.

In this interview we discuss the latest treatments and research for gastrointestinal cancers with Dr. Cathy Eng, associate professor, department of gastrointestinal medical oncology, The University of Texas MD Anderson Cancer Center.
