PURPOSE Perirectal spacing, whereby biomaterials are placed between the prostate and rectum, shows promise in reducing rectal dose during prostate cancer radiation therapy. A prospective multicenter randomized controlled pivotal trial was performed to assess outcomes following absorbable spacer (SpaceOAR system) implantation. METHODS AND MATERIALS(More)
PURPOSE To determine overall survival, progression-free survival, rate of voice preservation, and patterns of failure in locoregionally advanced laryngeal cancer treated with induction chemotherapy with or without surgery followed by concomitant chemoradiation. BACKGROUND Locoregionally advanced laryngeal cancer has been conventionally treated with either(More)
PURPOSE Impotence is a familiar sequela of both definitive external-beam radiotherapy (EBRT) and radical prostatectomy for localized prostate cancer. Among surgical options, nerve-sparing radical prostatectomy (NSRP) offers the highest potency preservation rate of 70%. We report the change in potency over time in an EBRT-treated population, determine the(More)
BACKGROUND AND PURPOSE Stereotactic body radiotherapy (SBRT) is being used for prostate cancer, but concerns persist about toxicity compared to other radiotherapy options. MATERIALS AND METHODS We conducted a multi-institutional pooled cohort analysis of patient-reported quality of life (QOL) [EPIC-26] before and after intensity-modulated radiotherapy(More)
OBJECTIVE To investigate whether patient-reported quality of life after high-dose external beam intensity-modulated radiotherapy for prostate cancer can be improved by decreasing planning target volume margins while using real-time tumor tracking. METHODS Study patients underwent radiotherapy with nominal 3-mm margins and electromagnetic real-time(More)
Stereotactic radiation approaches are gaining more popularity for the treatment of intracranial as well as extracranial tumors in organs such as the liver and lung. Technology, rather than biology, is driving the rapid adoption of stereotactic body radiation therapy (SBRT), also known as stereotactic ablative radiotherapy (SABR), in the clinic due to(More)
PURPOSE Impotence is a familiar sequela of definitive external beam radiation therapy (EBRT) for localized prostate cancer; however, nerve-sparing radical prostatectomy (NSRP) has offered potency rates as high as 70% for selected for patients in several large series. To the authors' knowledge, age and stage-matched comparisons between the effects of EBRT(More)
BACKGROUND Discrepancies exist regarding the impact of neoadjuvant hormone therapy (NHT) on the risk of all-cause mortality (ACM) in men who receive brachytherapy for localized prostate cancer. Therefore, the objective of the current study was to examine the effect of NHT on the risk of ACM in men with prostate cancer who receive with brachytherapy. (More)
PURPOSE Locoregionally advanced oropharyngeal cancer has been conventionally treated with either surgery and adjuvant radiotherapy or radiotherapy alone, and clinical and functional outcomes have been poor. Chemoradiotherapy has been demonstrated to improve functional outcome and disease control over conventional treatment in recent randomized head and neck(More)
Radiotherapy has conventionally been viewed as immunosuppressive, which has precluded its use in combination with immunotherapy for prostate and other cancers. However, the relationship between ionizing radiation and immune reactivity is now known to be more complex than was previously thought, and data on the use of radiotherapy and immunotherapy are(More)
