Randomized Controlled Trial Multicenter StudyThoracic radiotherapy with or without daily low-dose carboplatin in elderly patients with non-small-cell lung cancer: a randomised, controlled, phase 3 trial by the Japan Clinical Oncology Group (JCOG0301).
It is unknown whether combined chemoradiotherapy improves overall survival in elderly patients with locally advanced non-small-cell lung cancer (NSCLC). The aim of this study was to assess whether radiotherapy plus carboplatin results in longer survival than radiotherapy alone in elderly patients with NSCLC. ⋯ Ministry of Health, Labour, and Welfare of Japan.

Randomized Controlled Trial Multicenter Study Comparative StudyPreoperative chemoradiotherapy and postoperative chemotherapy with fluorouracil and oxaliplatin versus fluorouracil alone in locally advanced rectal cancer: initial results of the German CAO/ARO/AIO-04 randomised phase 3 trial.
Preoperative chemoradiotherapy, total mesorectal excision surgery, and adjuvant chemotherapy with fluorouracil is the standard combined modality treatment for rectal cancer. With the aim of improving disease-free survival (DFS), this phase 3 study (CAO/ARO/AIO-04) integrated oxaliplatin into standard treatment. ⋯ German Cancer Aid (Deutsche Krebshilfe).

ReviewRadiotherapy for head and neck tumours in 2012 and beyond: conformal, tailored, and adaptive?
Intensity-modulated radiation therapy (IMRT) is a conformal irradiation technique that enables steep dose gradients. In head and neck tumours this approach spares parotid-gland function without compromise to treatment efficacy. ⋯ Planned dose increases to parts of the target volumes may also be used to match the radiosensitivity of tumours (so-called dose-painting), assessed by molecular imaging. For swift implementation of tailored and adaptive IMRT, tools and procedures, such as accurate image acquisition and reconstruction, automatic segmentation of target volumes and organs at risk, non-rigid image and dose registration, and dose summation methods, need to be developed and properly validated.
