Purpose Stereotactic radiosurgery (SRS), whole-brain radiotherapy (WBRT), and epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) are treatment options for brain metastases in patients with EGFR-mutant non-small-cell lung cancer (NSCLC). This multi-institutional analysis sought to determine the optimal management of patients with(More)
BACKGROUND There are limited comparative survival data for prostate cancer (PCa) patients managed with a low-dose rate brachytherapy (LDR-B) boost and dose-escalated external-beam radiotherapy (DE-EBRT) alone. OBJECTIVE To compare overall survival (OS) for men with unfavorable PCa between LDR-B and DE-EBRT groups. DESIGN, SETTING, AND PARTICIPANTS Using(More)
Importance Postoperative radiotherapy to the craniospinal axis is standard-of-care for pediatric medulloblastoma but is associated with long-term morbidity, particularly in young children. With the advent of modern adjuvant chemotherapy strategies, postoperative radiotherapy deferral has gained acceptance in children younger than 3 years, although it(More)
BACKGROUND Elderly patients with early-stage breast cancer (ESBC) derive a local control benefit from radiotherapy (RT) after lumpectomy, without any apparent effect on overall survival. Therefore, the use of RT is controversial. In the current study, the authors characterized updated trends in RT for elderly patients with estrogen receptor (ER)-positive(More)
Background Although chemotherapy is used routinely in pediatric medulloblastoma (MB) patients, its benefit for adult MB is unclear. We evaluated the survival impact of adjuvant chemotherapy in adult MB. Methods Using the National Cancer Data Base, we identified patients aged 18 years and older who were diagnosed with MB in 2004-2012 and underwent surgical(More)
BACKGROUND Combined temozolomide and radiotherapy (RT) is the standard postoperative therapy for glioblastoma multiforme (GBM). However, the clearest benefit of concurrent chemoradiotherapy (CRT) observed in clinical trials has been among patients who undergo surgical resection. Whether the improved survival with CRT extends to patients who undergo "biopsy(More)
PURPOSE To investigate outcomes for elderly patients treated with chemotherapy (CT) alone versus chemoradiotherapy (CRT) in the modern era by using a large national database. PATIENTS AND METHODS Elderly patients (age ≥ 70 years) with limited-stage small-cell lung cancer clinical stage I to III who received CT or CRT were identified in the National Cancer(More)
PURPOSE Although whole-brain radiation therapy (WBRT) is effective for controlling intracranial disease, it is also associated with neurocognitive side effects. It is unclear whether a theoretically improved quality of life after stereotactic radiation surgery (SRS) alone relative to that after SRS with adjuvant WBRT would justify the omission of WBRT,(More)
BACKGROUND Stereotactic body radiotherapy (SBRT) is an efficacious treatment for early stage non-small cell lung cancer (NSCLC). Patients with clinically suspected NSCLC may have medical comorbidities that increase biopsy risks, making them more likely to receive SBRT without biopsy. This study characterizes the pervasiveness of this management approach(More)
The rate of contralateral prophylactic mastectomy (CPM) is rising rapidly, despite limited evidence about the procedure’s relative benefits and harms. The objective of this study is to examine the impact of CPM on life expectancy (LE) and quality-adjusted life expectancy (QALE) in women with sporadic unilateral breast cancer. A Markov model was developed to(More)
