PURPOSE: To report acute and late toxicity rates in patients with high-risk prostate cancer treated with androgen deprivation therapy (ADT) and moderate hypofractionated radiation therapy (HypoRT) to the prostate and nodal areas. METHODS AND MATERIALS: Patients with localized, high-risk prostate cancer were treated with a HypoRT regimen of 60 Gy in 20 fractions (4 weeks) to the prostate volume while the nodal areas received 44 Gy in the same 20 fractions delivered with intensity modulated RT with a simultaneous integrated boost technique...

PURPOSE: Reduction mammoplasty (RM) during breast-conserving surgery is popular among women with large-volume breasts because it reduces redundant breast folds and may decrease skin-related morbidity from radiation therapy. However, RM may obscure the lumpectomy cavity (LC) and pose challenges to administering an LC boost, potentially affecting local control. We investigated the impact of RM on acute side effects and use of LC boosts. METHODS AND MATERIALS: The records of 645 consecutive women treated with whole-breast irradiation at an urban university and 2 community practices between January 2012 and December 2014 were reviewed on an institutional review board-approved study...

PURPOSE/OBJECTIVE(S): Board certified radiation oncologists and medical physicists are required to earn self-assessment module (SAM) continuing medical education (CME) credit, which may require travel costs or usage fees. Data indicate that faculty participation in resident teaching activities is beneficial to resident education. Our hypothesis was that providing the opportunity to earn SAM credit in resident didactics would increase faculty participation in and improve resident education...

PURPOSE: The purpose of this study was to evaluate the impact of the active breathing control (ABC) technique on IMN coverage and organs at risk in patients planned for postmastectomy radiation therapy (PMRT), with the inclusion of the internal mammary lymph nodes (IMNs). The effect of body mass index (BMI) on recorded dosimetric parameters was examined in the same patient cohort. METHODS AND MATERIALS: Fifty left-sided postmastectomy patients with breast cancer who underwent free-breathing (FB) and ABC-Elekta CT simulation scans were selected at random from an institutional breast cancer database between 2008 and 2014...

PURPOSE: The purpose of this study was to assess the state of palliative and supportive care (PSC) and palliative radiation therapy (RT) educational curricula in radiation oncology residency programs in the United States. METHODS AND MATERIALS: We surveyed 87 program directors of radiation oncology residency programs in the United States between September 2015 and November 2015. An electronic survey on PSC and palliative RT education during residency was sent to all program directors...

PURPOSE: To quantify interfractional independent motions between multiple primary targets in radiation therapy (RT) of lung cancer and to study the dosimetric benefits of an online adaptive replanning method to account for these variations. METHODS AND MATERIALS: Ninety-five on-treatment diagnostic-quality computed tomography (CT) scans acquired for 9 lung cancer patients treated with image-guided RT (IGRT) using a CT-on-rails (CTVision, Siemens) were analyzed. On each on-treatment CT set, contours of the targets (gross tumor volume, clinical target volume, or involved nodes), and organs at risk were generated by populating the planning contours using an autosegmentation tool (ABAS, Elekta) with manual editing...

PURPOSE: Transperineal ultrasound (TPUS) allows for continuous imaging of the prostate gland, but the accuracy of TPUS has not been rigorously studied. We determined the feasibility of prostate imaging with TPUS and subsequently compared prostate localization with TPUS and computed tomography (CT). METHODS AND MATERIALS: We completed 2 sequential evaluations of TPUS. The feasibility study included 15 men with localized prostate cancer and tested if TPUS adequately imaged the prostate...

PURPOSE: Various cochlear dose surrogates have been reported as associated with hearing outcome in studies of stereotactic radiosurgery (SRS) for vestibular schwannomas. In this study, we investigated whether an inherent functional relationship exists among these reported surrogates. METHODS AND MATERIALS: A cohort of 85 serial patient cases treated with single-fraction stereotactic radiosurgery from 1997 through 2013 at our institution was analyzed. For all the cases, the mean prescription dose was 12...

PURPOSE: Preoperative short-course radiation therapy (SCRT) has rarely been used for rectal cancer in the United States, although 2 randomized phase 3 trials demonstrate equivalence to conventional chemoradiation (CRT), and recent updates to national guidelines include this regimen as a treatment option. We sought to evaluate the efficacy and safety of preoperative SCRT followed by immediate surgery within 1 week to treat rectal cancer in the US setting. METHODS AND MATERIALS: All patients treated with preoperative SCRT (4 Gy × 5 fractions for total 20 Gy) followed by planned surgery within 1 week at our institution were retrospectively evaluated...

PURPOSE: In 2012, we instituted detailed prospective peer review of new cases. We present the outcomes of peer review on patient management and time required for peer review. METHODS AND MATERIALS: Peer review rounds were held 3 to 4 days weekly and required 2 physicians to review pertinent information from the electronic medical record and treatment planning system. Eight aspects were reviewed for each case: 1) workup and staging; 2) treatment intent and prescription; 3) position, immobilization, and simulation; 4) motion assessment and management; 5) target contours; 6) normal tissue contours; 7) target dosimetry; and 8) normal tissue dosimetry...

PURPOSE: The purpose is to provide an update the Bone Metastases Guideline published in 2011 based on evidence complemented by expert opinion. The update will discuss new high-quality literature for the 8 key questions from the original guideline and implications for practice. METHODS AND MATERIALS: A systematic PubMed search from the last date included in the original Guideline yielded 414 relevant articles. Ultimately, 20 randomized controlled trials, 32 prospective nonrandomized studies, and 4 meta-analyses/pooled analyses were selected and abstracted into evidence tables...

PURPOSE: Nearly two-thirds of cancer patients seek information about their diagnosis online. We assessed the readability of online patient education materials found on academic radiation oncology department Web sites to determine whether they adhered to guidelines suggesting that information be presented at a sixth-grade reading level. METHODS AND MATERIALS: The Association of American Medical Colleges Web site was used to identify all academic radiation oncology departments in the United States...

PURPOSE: This study was designed to assess the efficacy and outcomes of argon plasma coagulation (APC) in the management of chronic radiation proctitis after conventionally fractionated, dose-escalated radiation therapy (≥7560 cGy). METHODS AND MATERIALS: We retrospectively reviewed the charts on all patients treated with external beam radiation therapy (minimum dose, 7560 cGy) for histologically confirmed prostate cancer at our institution from 2003 to 2011. Five hundred patients met these criteria; of these, 35 patients (7...
