Brachytherapy as part of the multidisciplinary treatment of childhood rhabdomyosarcomas of the orbit.
Rhabdomyosarcomas in the orbit form a major challenge in terms of cure without severe side effects in childhood cancer. Our specifically developed approach consists of applying brachytherapy to the tumor area using a mold. Analysis of its results for 20 patients was performed. ⋯ This entire procedure of brachytherapy with a mold offers a tailor-made treatment for orbital rhabdomyosarcomas with only few signs of late toxicity.

Radiation pneumonitis after hypofractionated radiotherapy: evaluation of the LQ(L) model and different dose parameters.
To evaluate the linear quadratic (LQ) model for hypofractionated radiotherapy within the context of predicting radiation pneumonitis (RP) and to investigate the effect if a linear (L) model in the high region (LQL model) is used. ⋯ For high fraction doses, the LQ model with an alpha/beta ratio of 3 Gy was the best method for converting the physical lung dose to predict RP.

Stereotactic body radiation therapy for early-stage non-small-cell lung cancer: the pattern of failure is distant.
Stereotactic body radiation therapy (SBRT) represents a substantial paradigm shift in the treatment of patients with medically inoperable Stage I/II non-small-cell lung cancer. We reviewed our experience using either three- or five-fraction SBRT for peripheral or central tumors, respectively. ⋯ Local tumor control was shown to be high using SBRT for non-small-cell lung cancer. Overall survival is highly coerrelated with the development of distant metastasis.

Multicenter StudyInitial efficacy results of RTOG 0319: three-dimensional conformal radiation therapy (3D-CRT) confined to the region of the lumpectomy cavity for stage I/ II breast carcinoma.
This prospective study (Radiation Therapy Oncology Group 0319) examines the use of three-dimensional conformal external beam radiotherapy (3D-CRT) to deliver accelerated partial breast irradiation (APBI). Initial data on efficacy and toxicity are presented. ⋯ Initial efficacy and toxicity using 3D-CRT to deliver APBI appears comparable to other experiences with similar follow-up. However, additional patients, further follow-up, and mature Phase III data are needed to evaluate the extent of application, limitations, and value of this particular form of APBI.
