The relationship between local dose and loss of function for irradiated lung.
To determine the relationship between the local radiation dose and the decrease in lung function associated with thoracic irradiation. ⋯ The decrease in pulmonary diffusion capacity correlates with the local dose to irradiated lung. Amifostine significantly reduces the loss in DL(CO). A local dose-loss relationship for normalized DL(CO) can be extracted from DVH data. This relationship allows an estimate of the loss of function associated with a radiation treatment plan. Different plans can thus be compared without resort to an empiric DVH reduction algorithm. The very low (13 Gy) threshold for deterioration of DL(CO) suggests that it is better to treat a little normal lung to a high dose than to treat a lot to a low dose.

Randomized Controlled Trial Multicenter Study Clinical TrialThe effect of supplemental beam radiation on prostate brachytherapy-related morbidity: morbidity outcomes from two prospective randomized multicenter trials.
To detail the effect of supplemental beam radiation on prostate brachytherapy-related morbidity. ⋯ The addition of supplemental beam radiation had little effect on morbidity. We do not believe that morbidity per se should influence the decision of whether or not to use supplemental beam radiation.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical TrialConcurrent mitomycin C, 5-fluorouracil, and radiotherapy in the treatment of locally advanced carcinoma of the cervix: a randomized trial.
This is a prospective, Phase III multicenter randomized trial to assess the effectiveness of concurrent intravenous mitomycin C, oral 5-fluorouracil (5-FU), and radiotherapy (RT) in locally advanced carcinoma of the cervix. ⋯ Concurrent chemotherapy, mitomycin C, and 5-FU together with conventional RT showed an improved DFS rate when compared with conventional RT alone in patients with locally advanced carcinoma of the cervix.

ReviewVolumetric considerations in radiotherapy for pediatric parameningeal rhabdomyosarcomas.
To assess the influence of radiation volume on outcome in pediatric parameningeal rhabdomyosarcomas (PM-RMSs). ⋯ Radiotherapy delivered to children with PM-RMS using a shrinking field technique with a post-CMT volume boost was effective and appears to give results comparable to those of patients in whom the pre-CMT volume was treated for the entire course. The use of such tailored treatment fields is likely to lead to fewer late effects and warrants further investigation.

ReviewHyperfractionated radiotherapy with concurrent chemotherapy for para-aortic lymph node recurrence in carcinoma of the cervix.
To evaluate efficacy, toxicity, and patterns of relapse in patients treated with hyperfractionated radiotherapy (HFRT) with concurrent chemotherapy for para-aortic lymph node (PALN) recurrence of cervical carcinoma. ⋯ HFRT of 60 Gy to PALN with concurrent chemotherapy could be regarded as an effective treatment modality without significant acute or late toxicity. Patients with a latent period >24 months until PALN recurrence had a more favorable survival rate than those with a latent period
