Randomized Controlled Trial Multicenter StudyQuality of Life in Relation to Pain Response to Radiation Therapy for Painful Bone Metastases.
To study quality of life (QoL) in responders and nonresponders after radiation therapy for painful bone metastases; and to identify factors predictive for a pain response. ⋯ Responding patients show a better QoL after radiation therapy for painful bone metastases than nonresponders. Our model did not have enough discriminative power to predict which patients are likely to respond to radiation therapy. Therefore, radiation therapy should be offered to all patients with painful bone metastases, aiming to decrease pain and improve QoL.

Observational StudyRadical Radiation Therapy After Lung-Sparing Surgery for Malignant Pleural Mesothelioma: Survival, Pattern of Failure, and Prognostic Factors.
To prospectively assess the survival, patterns of failure, and prognostic factors in a large cohort of patients with malignant pleural mesothelioma who had undergone a novel trimodal therapeutic approach, including lung-sparing surgery, chemotherapy, and subsequent treatment with high doses of intensity modulated radiation therapy (IMRT) to the whole hemithorax. ⋯ Radical IMRT after lung-sparing surgery and chemotherapy for malignant pleural mesothelioma leads to promising survival results and acceptable toxicity rates. The similarity of survival between patients treated with extended P/D or partial pleurectomy observed in our study is intriguing.

Comparative StudyMedical Malpractice Claims in Radiation Oncology: A Population-Based Study 1985-2012.
The purpose of this study was to determine trends in radiation oncology malpractice claims and expenses during the last 28 years and to compare radiation oncology malpractice claims to those of other specialties. ⋯ Medical professional liability claims filed against radiation oncologists are not common and have declined in recent years. However, indemnity payments in radiation oncology are large relative to those of many other specialties. In recent years, the average indemnity payment has been stable, whereas litigation expenses have increased.

Randomized Controlled TrialShort- and Long-Term Quality of Life and Bowel Function in Patients With MRI-Defined, High-Risk, Locally Advanced Rectal Cancer Treated With an Intensified Neoadjuvant Strategy in the Randomized Phase 2 EXPERT-C Trial.
Intensified preoperative treatments have been increasingly investigated in locally advanced rectal cancer (LARC), but limited data are available for the impact of these regimens on quality of life (QoL) and bowel function (BF). We assessed these outcome measures in EXPERT-C, a randomized phase 2 trial of neoadjuvant capecitabine combined with oxaliplatin (CAPOX), followed by chemoradiation therapy (CRT), total mesorectal excision, and adjuvant CAPOX with or without cetuximab in magnetic resonance imaging-defined, high-risk LARC. ⋯ Intensifying neoadjuvant treatment by administering induction systemic chemotherapy before chemoradiation therapy improves tumor-related symptoms and does not appear to have a significantly detrimental effect on QoL and BF, in both the short and the long term.

Observational StudyVentilation/Perfusion Positron Emission Tomography--Based Assessment of Radiation Injury to Lung.
To investigate (68)Ga-ventilation/perfusion (V/Q) positron emission tomography (PET)/computed tomography (CT) as a novel imaging modality for assessment of perfusion, ventilation, and lung density changes in the context of radiation therapy (RT). ⋯ Radiation-induced regional lung functional deficits occur in a dose-dependent manner and can be estimated by simple linear models with 4D-V/Q PET/CT imaging. These findings may inform future studies of functional lung avoidance using V/Q PET/CT.
