Annual Meeting of the American Radium Society (ARS)

An investigation of the association between deteriorating economic environment and utilization of postlumpectomy radiation therapy (PLRT) using a difference-in-differences (DID) model.

Although recent data have been published regarding trends surrounding mastectomy with reconstruction for breast cancer, little data exist about predictors of immediate vs delayed reconstruction and the prevalence of reconstruction where it is traditionally contraindicated, such as inflammatory breast cancer and stage IV disease.

Significant effort has been expended over the past decade to reduce racial disparities in breast cancer care. Whether disparities in receipt of appropriate radiotherapy care for breast cancer persisted despite these efforts is unknown, as is the impact of being eligible for Medicare.

Patients with abnormal screening mammogram (abSM) often experience prolonged wait times for additional testing to resolve the cause of the abnormality. The purpose of this study was to initiate an intervention, termed ‘reflex testing’ (RefT), and analyze pre- and post-RefT timelines to determine if, where, and in whom RefT resulted in significant decreases in timelines for resolution of abSM of patients undergoing routine screening in an accredited community hospital-based breast center.

Due to the rarity of Paget disease (PD), the role of breast conserving surgery (BCS) and radiation therapy (RT) is not fully defined. The specific aims of this analysis are to study national patterns of care in the local management of PD and to determine breast cancer–specific survival (BCSS) by type of treatment in a large population-based cohort.

Recent expert consensus statements have endorsed use of accelerated partial-breast irradiation (APBI) in select groups of low-risk women with early-stage breast cancer. APBI in the form of balloon brachytherapy is increasingly selected as a method of radiation treatment (RT).

In breast cancer, the primary site residual burden of disease (PRBD) after neoadjuvant chemotherapy has been shown to correlate with poor prognostic outcomes. Currently, there is no established standard of care to offer patients with residual disease, in terms of adjuvant systemic treatment after full-dose neoadjuvant chemotherapy.

The World Health Organization predicts that 26.4 million new cancer cases will be reported in 2030 alone. It is necessary to establish an effective mentoring paradigm in radiological science, not just for medical students (MS) but also for high school (HS) and college undergraduate (UG) students, to promote a greater general awareness of the study of oncology as well as its therapeutic implementation.

There are over 3.0 million cases of nonmelanoma skin cancer (NMSC) diagnosed each year in the United States. Multiple treatment options exist for the treatment of these patients. We describe the outcomes of patients treated at a large private dermatology practice with electronic brachytherapy (eBx) who had a minimum follow-up duration of 1 year.

The long-term outcomes of radiation therapy (RT) in patients infected with human immunodeficiency virus (HIV) who have benign lymphoepithelial cysts (BLECs) of the parotid glands are reported.

Electronic brachytherapy for skin cancer is now available without the need for room shielding. Advances in radiobiology and radiotechnology permit the treatment course to be given in eight fractions over 4 weeks. This report describes the experience with our first 565 treated lesions.

Thymic tumors are a rare disease and have been treated in a similar manner without convincing data. We present our institutional results of outcomes between invasive thymoma and thymic carcinoma.

Patients who sustain brain and spinal cord injuries are at risk for developing neurogenic heterotopic ossification (NHO), the formation of bone in extraskeletal soft tissue. The purpose of this study was to review the experience and to report the outcome of eight consecutively irradiated joints in four patients with NHO.

Linear accelerator–based stereotactic radiosurgery (SRS) is a treatment option for melanoma patients who have developed brain metastases. Few data are available on treatment of patients with ≥ 5 lesions. We sought to determine the effectiveness of SRS in patients with ≥ 5 melanoma brain metastases.

In the United States, an estimated 48 million individuals live without health insurance. The purpose of this study is to explore differences in key factors associated with insurance status among non-Medicare-aged adults diagnosed with the top 25 incident cancers using the Surveillance, Epidemiology, and End Results (SEER) public-use database.

As the volume of radiation oncology information increases, the ability to gather and critically appraise high-quality information in order to answer clinical questions becomes increasingly challenging for radiation oncologists. Sharing knowledge about new information and practice variations is instrumental to high-quality radiation oncology practices.

The standard approach for palliation of bone metastasis (BM) is conventionally planned radiation (CRT). Randomized studies have shown the equivalence of hypofractionated vs conventionally fractionated regimens; yet, reported pain control is poor with either approach, resulting in some degree of pain relief in only 50% to 80% of cases and complete response in 15% to 60% of cases.

NRG Oncology is a member of the National Cancer Institute (NCI) National Clinical Trials Network program and was created by the integration of three adult cooperative groups: the National Surgical Adjuvant Breast and Bowel Project (NSABP), the Radiation Therapy Oncology Group (RTOG), and the Gynecologic Oncology Group (GOG). The Publications Working Group, has begun the amalgamation of three publications databases into one to track progress in manuscript development and to provide access to a comprehensive bibliography that incorporates the past/current research of all three legacy groups.

With the increasing patient population in the oncology world and advancing technologies in radiation oncology in particular, there is an increasing need for assistance in providing high-quality care.

This retrospective analysis concentrates on our institutional experience with transarterial radioembolization (TARE) for the treatment of liver metastasis from neuroendocrine cancer.

Advances in intensity-modulated radiation therapy (IMRT) head and neck target delineation and treatment planning have led to improved sparing of organs at risk (OARs). In this study, we compare three IMRT techniques for the treatment of common cases of oropharyngeal squamous cell carcinoma.

Step-and-shoot intensity-modulated radiation therapy (IMRT) and variable-dose-rate volumetric modulated arc therapy (VMAT) are two common treatment techniques for the definitive treatment of prostate cancer. In order to compare these two techniques in modern practice, we analyzed two cohorts of patients treated at our institution who were matched for PTV, prescribed dose, and patient characteristics.

Today’s health care system is evolving in its approach to the management of an ethnically diverse population, as it continues to struggle with the imperative of providing cost-effective care. This study attempts to assess the level of knowledge and interest current residents have in CAM teachings, with the goal of eventually incorporating such evidence-based study into training curriculum.

Radiation pneumonitis (RP) is a significant toxicity following thoracic radiotherapy, with no method to predict individual risk. Our lab had previously shown that pulmonary metabolic response rate (PMRR) is highly predictive of RP in lung cancer. In this prospective study, we used PMRR as a surrogate marker to predict radiation-induced lung toxicity in lung cancer patients receiving thoracic radiotherapy.

We report the initial prostate-specific antigen (PSA) control and toxicity profile of patients treated using IBCL seeds with the QuickLink device for permanent prostate brachytherapy.

The clinical effect of perfusion single-photon emission computed tomography (SPECT) image-guided planning in patients treated for locally advanced and metastatic lung cancers is assessed.

To evaluate outcomes and toxicity of concurrent full-dose gemcitabine and intensity-modulated radiation therapy (IMRT) for patients with borderline resectable and locally advanced pancreatic adenocarcinoma following induction chemotherapy.

A retrospective study was performed to investigate potential prognostic indicators and evaluate treatment outcomes in patients diagnosed with locally advanced unresectable pancreatic cancer (LAUPC), treated with chemotherapy alone (C), concurrent chemoradiation therapy (CRT), induction C followed by concurrent chemoradiation (C-CRT), CRT followed by chemotherapy (CRT-C), or C-CRT followed by C (C-CRT-C).

To compare toxicity and treatment outcomes in human immunodeficiency virus (HIV)-positive vs HIV-negative patients with squamous cell carcinoma of the anal canal who underwent definitive concurrent chemoradiation at a single institution.

Cerebral arteriovenous malformation (AVM) is defined as an abnormal collection of vessels with multiple enlarged feeder arteries and dilated venous outflow, associated with risks of blood shunting and hemorrhage. Treatment options include surgery, embolization, or stereotactic radiosurgery (SRS).
