We evaluated changes in incidence, relative survival (RS), and conditional survival (CS) of head and neck squamous cell carcinoma (HNSCC), focusing on oral tongue squamous cell carcinoma (OTSCC). Data of 74 680 HNSCC patients from 1976 to 2015 were obtained from the Surveillance, Epidemiology, and End Results database. Five anatomical sites and their subsites were analyzed. Annual percent change (APC) of incidence was calculated. RS and CS were compared across the four decades. Adjusted hazard r

The novel LCP-based cochlear implant provides a good MRI compatibility beyond present-day cochlear implants. Thus, MR images can be obtained from the subjects even with the implanted LCP-based neural prosthetic systems providing useful diagnostic information. Furthermore, it will be also useful for functional MRI studies of the auditory perception mechanism after cochlear implantations as well as for positron emission tomography-MRI hybrid imaging.

OBJECTIVE: To investigate the feasibility and efficacy of stereotactic body radiotherapy as salvage treatment for cervical node recurrence from nonanaplastic thyroid cancer refractory to other modalities. STUDY DESIGN: Pilot study. SETTING: A single institution-based practice. SUBJECTS AND METHODS: Between August 2002 and November 2007, nine patients with recurrent nonanaplastic thyroid cancer were treated with stereotactic body radiotherapy for nodal metastases. Radiotherapy was delivered in on

This study compared adaptive replanning and repositioning corrections based on soft-tissue matching for prostate cancer by using the magnetic resonance-guided radiation therapy (MRgRT) system. A total of 19 patients with prostate cancer were selected retrospectively. Weekly magnetic resonance image (MRI) scans were acquired for 5 weeks for each patient to observe the anatomic changes during the treatment course. Initial intensity-modulated radiation therapy (IMRT) plans (iIMRT) were generated fo

PURPOSE: This study compares the plan quality of magnetic-resonance image (MRI)-based intensity modulated radiation therapy (IMRT) using a linac (MR-linac-IMRT), MRI-based IMRT using tri-Co-60 sources (MR-Co-60-IMRT), and volumetric modulated arc therapy (VMAT) for spine stereotactic ablative radiotherapy (SABR). METHODS: Twenty patients with thoracic spine metastasis were retrospectively selected for this study. For each patient, the MR-linac-IMRT, MR-Co-60-IMRT, and VMAT plans were generated u

Isotype-specificity exists in HDAC inhibition-induced radiosensitization. Different HDAC isotypes are differentially involved in modulation of cellular radiosensitivity.

TSA and SK-7041 enhances radiosensitivity only when delivered before irradiation. Unless proven otherwise, it seems prudent to apply scheduling including preirradiation HDAC inhibition so that maximal radiosensitization is obtained.

PURPOSE: To evaluate the feasibility and the outcomes of transjugular percutaneous endovascular treatment of dysfunctional hemodialysis access in patients with chronic kidney disease. METHODS: A total of 50 transjugular treatments in 38 patients with arteriovenous fistulas or arteriovenous grafts from September 2011 to May 2015 were included in this study. Medical records and angiographies were retrospectively reviewed. Success rate, patency rate, procedure time, and complications including inte

Of ophthalmic involvement from metastatic breast cancer, extraocular/intraorbital metastases are extremely rare. External beam radiotherapy has been a mainstay palliation for symptomatic orbital metastases. We present a case of bilateral orbital metastases from breast cancer successfully treated with stereotactic radiotherapy (SRT). A 38-year-old woman presented with decreased vision in the right eye for 3 weeks. Eight months previously, she underwent whole-brain radiotherapy for multiple brain
