Randomized, Multicenter, Phase IIB Study of Preoperative Chemoradiotherapy in T3 Mid-Distal Rectal Cancer: Raltitrexed + Oxaliplatin + Radiotherapy Versus Cisplatin + 5-Fluorouracil + Radiotherapy

Compared with the PLAFUR regimen, TOMOX-RT achieved a greater incidence of downstaging but was associated with a correspondingly greater rate of acute Grade 3+ toxicity. With longer follow-up, the local control and survival rates might offer additional guidance as to the choice of regimen.
