Summary
Brief summary (as posted)
The purpose of this study is to assess the effects, both good and bad, of adding very low dose fractionated radiation therapy (LDFRT) to the pelvis, with FOLFOX chemotherapy prior to surgery. Standard pelvic radiation therapy given once a day (Monday through Friday) over approximately 5.5 weeks is not given in this study. You will receive 6 cycles of FOLFOX (each cycle is 2 weeks) and you will also get an LDFRT to your pelvis given twice a day on the first two days of each cycle.
