..We therefore compared patterns of PRT use, cost, and early toxicity among Medicare beneficiaries with prostate cancer with those of intensity-modulated radiotherapy (IMRT)...

..We performed a retrospective cohort study of Medicare patients treated with IMRT compared with standard RT to assess outcomes in national practice...

..The Roach formula (RF) has been criticized as overestimating LN risk. A modification of the RF has been attempted by other investigators using simplified adjustment ratios: the Nguyen formula (NF)...

..The role of postmastectomy radiotherapy (PMRT) for lymph node-negative locally advanced breast carcinoma (T3N0M0) after modified radical mastectomy (MRM) with regard to improvement in survival remains an area of controversy...

..The nomogram is based on patients undergoing radical prostatectomy at The Johns Hopkins Medical Institutions. We validated the Partin tables in a large, population based sample...

..Although treatment guidelines were changed to indicate that some women could forego RT, the impact of the C9343 results on clinical practice is unclear...

..New radiation therapy modalities have broadened treatment options for older women with breast cancer, but it is unclear how clinical factors, geographic region, and physician preference affect the choice of radiation therapy modality...

..To determine whether whole pelvic radiotherapy (WPRT) or prostate-only radiotherapy (PORT) yields improved biochemical disease-free survival (BDFS) in patients with advanced or aggressive prostate adenocarcinoma...

..Little is known about the impact of physicians and regional factors on the use of RT across LE groups...

..To assess the impact of pretreatment prostate volume on the development of severe acute genitourinary toxicity in patients undergoing intensity-modulated radiation therapy (IMRT) for prostate cancer...

..Large studies examining the clinical and pathological factors associated with nodal metastasis in minor salivary gland cancer are lacking in the literature...

..Brachytherapy has disseminated into clinical practice as an alternative to whole-breast irradiation (WBI) for early-stage breast cancer; however, current national treatment patterns and associated complications remain unknown...

..To examine the importance of midline involvement and other clinicopathologic factors in predicting the rate of contralateral lymph node metastasis and survival in oral tongue squamous cell carcinoma...

..According to guidelines most men with incident prostate cancer do not require staging imaging. We determined the population level prevalence and correlates of appropriate and inappropriate imaging in this cohort...

..To evaluate the influence of immortal time bias on observational cohort studies of postoperative radiotherapy (PORT) and the effectiveness of sequential landmark analysis to account for this bias...

..The effect of adjuvant radiation therapy (RT) on survival in patients with adenoid cystic carcinoma (ACC) is much debated. Studies with large numbers of patients and long follow-up are lacking in the literature...

..Microcystic adnexal carcinoma (MAC) is a very rare cancer of the skin. It has only been described previously in case reports and small retrospective series...

..To investigate testicular doses contributed by kilovoltage cone-beam computed tomography (kVCBCT) during image-guided radiotherapy (IGRT) of prostate cancer...

..Despite its expense and controversy surrounding its benefit, the surgical robot has been widely adopted for the treatment of prostate cancer...

..This study was performed to evaluate the clinical outcomes of surgery for stage I small cell lung cancer (SCLC)...

....

..To evaluate trends in the geographic distribution of the radiation oncology (RO) workforce...

..To record changes in rectal volume (RV) and diameter (RD) of patients with prostate adenocarcinoma prior to and at an interim period during radiotherapy, which could potentially affect treatment toxicity and tumor control...

..This prospective study was initiated to evaluate perceptions of total skin electron beam therapy (TSEBT) by patients with mycosis fungoides who had failed at least 3 prior therapies...

..This study was undertaken to assess historical trends in the use of radiation therapy (RT) for pediatric cancers over the past 4 decades...

....

..The objective of the current study was to analyze demographic characteristics and outcomes for patients with this malignancy from a large United States-based population registry...

..We discuss the known side effects from SRT, weigh the cost and benefit of SRT, and discuss possible tools that may improve the cost/benefit ratio for SRT by helping to select patients whom SRT may be more likely to benefit...

..The primary intention of the analysis of the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) database was to report epidemiologic information and overall survival of patients with PCLPD...

..Physician knowledge and careful judgment, together with careful treatment planning and delivery can minimize the risks associated with brain metastasis radiosurgery...

..Finally, we discuss the cost-effectiveness of ART, in the context of other medical interventions...

..Extrahepatic bile duct cancers (EBDC) are aggressive cancers for which the importance of the use of postoperative radiation therapy (PORT) in potentially curative cases remains the subject of clinical investigation...

..This article reviews the current role of neurosurgery and radiation therapy in the management of primary brain tumors...

..Our aims are to help clinicians and policy makers interpret studies generated using GIS, and to help clinical investigators implement GIS in future research...

..Policies aimed at narrowing disparities in treatment may need to focus on addressing regional variations in oncology resources...

..Recognition of the acute, early delayed, and late complications of brain irradiation is essential to optimize management and mitigate their clinical impact...

..To analyze error disclosure attitudes of radiation oncologists and to correlate error disclosure beliefs with survey-assessed disclosure behavior...

..These findings have significant implications regarding need for earlier diagnosis and understanding the reasons for racial disparity in age and stage of presentation...

..We also discuss recent nonrandomized evidence for the use of SRS alone for oligometastatic disease...

..No major side effects from radiation were seen. CONCLUSIONS Vision, MRI and complication outcomes are favourable for using fractionated conformal radiotherapy for ONSM...

..Primary cutaneous CD30+ anaplastic large-cell lymphoma (CALCL) is a relatively rare and indolent variant of cutaneous T-cell lymphoma (CTCL). This report examines the response of localized disease to radiation alone...
