Comparative StudyTumor location, cirrhosis, and surgical history contribute to tumor movement in the liver, as measured during stereotactic irradiation using a real-time tumor-tracking radiotherapy system.
To investigate the three-dimensional (3D) intrafractional motion of liver tumors during real-time tumor-tracking radiotherapy (RTRT). ⋯ Tumor location, cirrhosis, and history of surgery on the liver all had an impact on the intrafractional tumor motion of the liver in the transaxial direction. This finding should be helpful in determining the smallest possible margin in individual cases of radiotherapy for liver malignancy.

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.

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.

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
