简要总结
Study design:
A prospective phase II, non-randomized observational study of dose-escalated pencil beam proton therapy re-irradiation for pelvic recurrences from rectal cancer.
Re-irradiation is either a part of neo-adjuvant treatment or as a definitive treatment strategy for un-resectable recurrences.
