Randomized Controlled Trial Multicenter StudyQuality control of involved field radiotherapy in patients with early-favorable (HD10) and early-unfavorable (HD11) Hodgkin's lymphoma: an analysis of the German Hodgkin Study Group.
The German Hodgkin Study Group (GHSG) set up a radiotherapy (RT) reference center within the Department of Radiation Oncology at the University of Cologne to undertake quality assurance of the group's clinical studies. In the HD10 trial (early-favorable stages) and HD11 trial (early-unfavorable stages) all patients received involved field (IF)-RT (30 Gy vs. 20 Gy) within a combined-modality approach. For these patients a central prospective review of all diagnostic imaging was performed by expert radiation oncologists to control disease extension and to define IF treatment volume. ⋯ As a consequence of these findings, radiation oncologists were trained on the definition of IF-RT at GHSG meetings and at the annual meetings of the German Society for Therapeutic Radiation Oncology. Possible correlations between RT quality and relapse rate will be investigated.

Randomized Controlled Trial Comparative StudyPreliminary results of a prospective randomized trial comparing concurrent chemoradiotherapy plus adjuvant chemotherapy with radiotherapy alone in patients with locoregionally advanced nasopharyngeal carcinoma in endemic regions of china.
A prospective randomized trial was performed to evaluate the efficacy of concurrent chemotherapy and adjuvant chemotherapy in patients with locoregionally advanced nasopharyngeal carcinoma (NPC) in endemic regions of China. ⋯ This trial demonstrated the significant survival benefits of concurrent chemotherapy plus adjuvant chemotherapy in patients with locoregionally advanced NPC in endemic regions of China.

Multicenter Study Comparative StudyInfluence of organ motion on conformal vs. intensity-modulated pelvic radiotherapy for prostate cancer.
To compare an intensity-modulated radiotherapy (IMRT) planning approach for prostate pelvic RT with a conformal RT (CRT) approach taking into account the influence of organ-at-risk (OAR) motion. ⋯ Intensity-modulated RT reduced the bowel, rectum, and bladder gEUDs also under influence of OAR motion. Neither CRT nor IMRT was robust against bowel motion, but IMRT was not less robust than CRT.

ReviewImpact of drug therapy, radiation dose, and dose rate on renal toxicity following bone marrow transplantation.
To demonstrate a radiation dose response and to determine the dosimetric and chemotherapeutic factors that influence the incidence of late renal toxicity following total body irradiation (TBI). ⋯ A dose response for renal damage after TBI was identified. Fractionation and low dose rates are factors to consider when delivering TBI to patients undergoing bone marrow transplantation. Drug therapy also has a major impact on kidney function and can modify the dose-response function.

Body mass index and prostate-specific antigen failure following brachytherapy for localized prostate cancer.
Increasing body mass index (BMI) is associated with prostate-specific antigen (PSA) failure after radical prostatectomy and external beam radiation therapy (EBRT). We investigated whether BMI is associated with PSA failure in men treated with brachytherapy for clinically localized prostate cancer. ⋯ Unlike after surgery or EBRT, BMI is not associated with PSA failure in men treated with brachytherapy for prostate cancer. This raises the possibility that brachytherapy may be a preferred treatment strategy in obese patients.
