Randomized Controlled Trial Multicenter Study Comparative StudyPreoperative chemoradiotherapy for rectal cancer: randomized trial comparing oral uracil and tegafur and oral leucovorin vs. intravenous 5-fluorouracil and leucovorin.
To compare, in a randomized trial, 5-fluorouracil (FU) plus leucovorin (LV) (FU+LV) vs. oral uracil and tegafur (UFT) plus LV (UFT+LV) given concomitantly with preoperative irradiation in patients with cT3-4 or N+ rectal cancer. ⋯ Although this study lacked statistical power to exclude clinically significant differences between both groups, the outcome of patients treated with UFT+LV did not differ significantly from that of patients treated with FU+LV, and hematologic toxicity was significantly lower in the experimental arm.

Randomized Controlled Trial Multicenter Study Comparative StudyComparison of treatment tolerance and outcomes in patients with cervical cancer treated with concurrent chemoradiotherapy in a prospective randomized trial or with standard treatment.
To compare the treatment and outcomes of cervical cancer patients treated with concurrent chemoradiotherapy (CT-RT) in a multi-institutional trial or as standard care. ⋯ Even within a large comprehensive cancer center, the high rates of chemotherapy completion achieved on a multi-institutional trial can be difficult to reproduce in standard practice. Although C/F toxicity was greater in the standard care patients, their outcomes were similar to those of patients treated with C/F on Radiation Therapy Oncology Group protocol 90-01.

Multicenter Study Comparative StudyAccelerated partial-breast intensity-modulated radiotherapy results in improved dose distribution when compared with three-dimensional treatment-planning techniques.
To compare dose distribution and normal tissue sparing in partial-breast treatment using three-dimensional conformal radiotherapy (3D-CRT) vs. intensity-modulated radiotherapy (IMRT). ⋯ In T1N0 patients treated with external beam partial-breast radiotherapy, IMRT improves normal tissue sparing in the ipsilateral breast compared with 3DRT, without compromising dose delivery to the lumpectomy cavity and clinical target volume.
