Clinical Trial
Active raster scanning with carbon ions: reirradiation in patients with recurrent skull base chordomas and chondrosarcomas.
To evaluate the safety and efficacy of reirradiation with carbon ions in patients with relapse of skull base chordoma and chondrosarcoma. ⋯ Reirradiation with carbon ions is a safe and effective method in patients with relapsed chordoma and chondrosarcoma of the skull base.

Multicenter Study Comparative Study
Evaluation of time, attendance of medical staff and resources for radiotherapy in pediatric and adolescent patients. The DEGRO-QUIRO trial.
The German Society of Radiation Oncology (DEGRO) initiated a multicenter trial to develop and evaluate adequate modules to assert core procedures in radiotherapy. The aim of this prospective evaluation was to methodical assess the required resources for radiotherapy in pediatric and adolescent patients. ⋯ For the first time, the personnel time requirements of a radiotherapy department for the maintenance, protection, and optimization of operational readiness for radiotherapy in pediatric and adolescent patients with and without general anesthesia were determined methodically.

A number of national and international societies published recommendations regarding the required equipment and manpower assumed to be necessary to treat a number of patients with radiotherapy. None of these recommendations were based on actual time measurements needed for specific radiotherapy procedures. The German Society of Radiation Oncology (DEGRO) was interested in substantiating these recommendations by prospective evaluations of all important core procedures of radiotherapy in the most frequent cancers treated by radiotherapy. The results of the examinations of radiotherapy with intensity-modulated radiation therapy (IMRT) in patients with different tumor entities are presented in this manuscript. ⋯ The prospective data presented here allow for an estimate of the required machine time and manpower needed for the core procedures of radiotherapy in an average radiation treatment with IMRT. However, one should be aware that a number of necessary and time-consuming activities were not evaluated in the present study.

The aim of this study was to report the 5-year results of accelerated partial breast irradiation (APBI) using external beam three-dimensional conformal radiotherapy (3D-CRT). ⋯ The 5-year local tumor control, toxicity profile, and cosmetic results of APBI delivered with external beam 3D-CRT are encouraging and comparable to other APBI series.
