| 1 | Current debate in the oncologic management of rectal cancer显示文摘Despite the considerable amount of research in the field,the management of locally advanced rectal cancer remains a subject to debate.To date,effective treatment centers on surgical resection with the standard approach of total mesorectal resection.Radiation therapy and chemotherapy have been incorporated in order to decrease local and systemic recurrence.While it is accepted that a multimodality treatment regimen is indicated,there remains significant debate for how best to accomplish this in regards to order,dosing,and choice of agents.Preoperative radiation is the standard of care,yet remains debated with the option for chemoradiation,short course radiation,and even ongoing studies looking at the possibility of leaving radiation out altogether.Chemotherapy was traditionally incorporated in the adjuvant setting,but recent reports suggest the possibility of improved efficacy and tolerance when given upfront.In this review,the major studies in the management of locally advanced rectal cancer will be discussed.In addition,future directions will be considered such as the role of immunotherapy and ongoing trials looking at timing of chemotherapy,inclusion of radiation,and nonoperative management. | Trish Millard Paul R Kunk Erika Ramsdale Osama E Rahma | 2016 | World Journal of Gastrointestinal Oncology2016，8，10： | 3 |
