The publisher regrets the following typesetting error on page 182 within a sentence which was typeset as follows: Lakoff's constraint can be rephrased in this way: Regular central senses imply regular extended senses: or by contra position, irregular extended senses imply regular central senses. The last instance of " regular " should have been typeset as "(More)
PURPOSE To report on the outcomes of a phase I study of stereotactic body radiotherapy (SBRT) for treatment of liver metastases. PATIENTS AND METHODS Patients with liver metastases that were inoperable or medically unsuitable for resection, and who were not candidates for standard therapies, were eligible for this phase I study of individualized SBRT.(More)
PURPOSE To define human papillomavirus (HPV) -positive oropharyngeal cancers (OPC) suitable for treatment deintensification according to low risk of distant metastasis (DM). PATIENTS AND METHODS OPC treated with radiotherapy (RT) or chemoradiotherapy (CRT) from 2001 to 2009 were included. Outcomes were compared for HPV-positive versus HPV-negative(More)
BACKGROUND This study was undertaken to determine outcomes of stereotactic body radiotherapy for colorectal liver metastases in a pooled patient cohort. METHODS Patients with colorectal liver metastases from 3 institutions were included if they had 1 to 4 lesions, received 1 to 6 fractions of stereotactic body radiotherapy, and had radiologic imaging ≥ 3(More)
PURPOSE A significant proportion of oropharyngeal squamous cell carcinomas (OSCC) are associated with the human papilloma virus (HPV), particularly HPV16. The optimal method for HPV determination on archival materials however, remains unclear. We compared a quantitative real-time polymerase chain reaction (qRT-PCR) assay for HPV16 mRNA to a DNA in situ(More)
PURPOSE To quantify the interfraction and breathing organ motion during adjuvant radiotherapy for gastric cancer and assess organ stability in different breathing states. METHODS AND MATERIALS A planning computed tomography (CT) scan and serial study CT scans in free breathing, voluntary inhale and exhale were performed in weeks 1, 3, and 5 of(More)
PURPOSE To determine whether a change in treatment policy to conformal, elective nodal radiotherapy and concurrent high-dose cisplatin improved survival for cervical esophageal cancer patients. METHODS AND MATERIALS All cervical esophageal cancer patients treated between 1997 and 2005 were restaged (1983 American Joint Committee on Cancer criteria).(More)
PURPOSE To describe outcomes of prospective trials of stereotactic body radiotherapy (SBRT) for hepatocellular carcinoma (HCC). PATIENTS AND METHODS Two trials of SBRT for patients with active HCC unsuitable for standard locoregional therapies were conducted from 2004 to 2010. All patients had Child-Turcotte-Pugh class A disease, with at least 700 mL of(More)
This paper presents a comprehensive extension of the Scale Invariant Feature Transform (SIFT), originally introduced in 2D, to volumetric images. While tackling the significant computational efforts required by such multiscale processing of large data volumes, our implementation addresses two important mathematical issues related to the 2D-to-3D extension.(More)
PURPOSE The role of primary radiotherapy (RT) for laryngeal verrucous carcinoma (LVC) is controversial because of concerns about anaplastic transformation, an increased incidence of metastases, and poorer local control after RT. To address these concerns, we report our experience. METHODS AND MATERIALS All patients with pathologically diagnosed LVC(More)
