Areas of research include: Personalized cell therapy. The goal of this study is to build a library of rectal cancer cells taken from patients, which can be used to develop more-personalized treatment strategies. Robotic versus laparoscopic surgery. This study compares robotic and conventional laparoscopic surgery for rectal cancer by assessing how each approach affects bowel, urinary and sexual function after surgery. Presurgery treatment. This study compares two treatments for rectal cancer before surgery — standard chemotherapy with radiation versus chemotherapy alone — to see which works better and causes fewer side effects.
