Promising clinical outcome of stereotactic body radiation therapy for patients with inoperable Stage I/II non-small-cell lung cancer.
To evaluate the efficacy and toxicity of hypofractionated stereotactic body radiotherapy in patients with Stage I/II non-small-cell lung cancer. ⋯ Our highly focused stereotactic body radiotherapy method resulted in promising local control and survival with minimal toxicity.

Randomized Controlled TrialEffectiveness of a clinical intervention in improving pain control in outpatients with cancer treated by radiation therapy.
To determine the effectiveness of a multicomponent clinical intervention to reduce pain in outpatients with cancer. ⋯ An intervention including patient education, a pain diary, and defining a procedure for therapeutic adjustments can be effective to improve pain relief in outpatients with cancer.

Risk factors for acute esophagitis in non-small-cell lung cancer patients treated with concurrent chemotherapy and three-dimensional conformal radiotherapy.
To determine the risk factors for acute esophagitis (AE) in non-small-cell lung cancer (NSCLC) patients treated with concurrent chemotherapy (CCT) and three-dimensional conformal radiotherapy (3D-CRT). ⋯ The risk of AE in the NSCLC patients treated with CCT and 3D-CRT was primarily determined by dosimetric factors. These factors should be carefully considered during treatment planning to minimize the incidence of AE.

Rectal bleeding, fecal incontinence, and high stool frequency after conformal radiotherapy for prostate cancer: normal tissue complication probability modeling.
To analyze whether inclusion of predisposing clinical features in the Lyman-Kutcher-Burman (LKB) normal tissue complication probability (NTCP) model improves the estimation of late gastrointestinal toxicity. ⋯ Inclusion of predisposing clinical features significantly improved the estimation of the NTCP. For patients with a history of abdominal surgery, more severe dose constraints should therefore be used during treatment plan optimization.

Randomized Controlled TrialContinuing evidence for poorer treatment outcomes for single male patients: retreatment data from RTOG 97-14.
The specific aim of this study was to evaluate outcome differences by gender and partner status for patients treated on Radiation Therapy Oncology Group (RTOG) protocol 97-14. ⋯ Non-disease-related variables, such as social support, might influence the results of clinical trials with subjective endpoints such as retreatment rates. The statistically nonsignificant difference in the 36-month retreatment rates observed in single male patients receiving 8 Gy may be a result of inadequate social support systems in place to facilitate additional care. Patients receiving 8 Gy in a single fraction had significantly higher retreatment rates compared with patients receiving 30 Gy in 10 fractions.
