In vivo, tissue-level, mechanical thresholds for axonal injury were determined by comparing morphological injury and electrophysiological impairment to estimated tissue strain in an in vivo model of axonal injury. Axonal injury was produced by dynamically stretching the right optic nerve of an adult male guinea pig to one of seven levels of ocular displacement (Nlevel = 10; Ntotal = 70). Morpho...

BACKGROUND Laser cordectomy is gaining popularity for treatment of early glottic carcinoma, but little is known about vocal and quality of life (QOL) outcomes as a function of extent of resection. We prospectively examined QOL and vocal function of patients with carcinoma in situ (Tis) or T1 glottic carcinomas after laser cordectomy. METHODS Patients (n = 75) were grouped into those who under...

BACKGROUND The purpose of this study was to assess the quality of life (QOL) and voice handicap in a sample of disease-free patients who had been treated at our center with radiotherapy (RT) or surgery for early glottic cancer. METHODS QOL and voice handicap were assessed using the European Organisation for Research and Treatment of Cancer (EORTC) questionnaires Quality of Life Questionnaire-...

Two-dimensional conventional radiotherapy (2D-CRT) and intensity-modulated radiotherapy (IMRT) are effective for control of nasopharyngeal carcinoma (NPC). The purpose of this study was to compare the quality of life (QoL) of stage II NPC patients treated with 2D-CRT versus IMRT. We conducted a cross-sectional study of 106 patients with stage II NPC treated with 2D-CRT (n = 47) versus IMRT (n =...

Purpose: The study evaluated the feasibility, clinical effectiveness, and quality of life of computed tomography (CT)-guided 125I brachytherapy for locally recurrent nasopharyngeal carcinoma (NPC). Methods: We recruited 81 patients diagnosed with locally recurrent NPC after previous radiotherapy with or without chemotherapy. Thirty-nine patients received 125I brachytherapy (group A) and 42 rece...

BACKGROUND The purpose of this study was to investigate late toxicities and quality of life (QOL) of patients with nasopharyngeal carcinoma (NPC) with long-term survival after treatment by intensity-modulated radiotherapy (IMRT) versus non-IMRT. METHODS An observational, cross-sectional study of QOL and late toxicities was conducted in 242 patients with NPC with survival of >5 years after tre...

BACKGROUND Health-related quality of life (HRQOL) has received more and more attention as an outcome in cancer therapy. In this exploratory study, we assessed the long-term HRQOL among 77 surgically treated patients with parotid gland cancer. METHODS The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30-questions (EORTC-QLQ-C30) and European Orga...

This study aimed to investigate the effects of Qigong intervention on quality of life (QOL), health-related functioning, and cancer-related symptoms in survivors of nasopharyngeal cancer (NPC). Twenty-five survivors of NPC were included in the experimental group (mean age ± SD: 55.4 ± 7.5 years) and 27 in the control group (mean age ± SD: 58.7 ± 9.5 years). The experimental group underwent a we...

BACKGROUND A Speech Handicap Index (SHI) questionnaire with 30 items on speech problems was developed and validated in 92 patients with cancer of the oral cavity or pharynx and 110 healthy subjects. METHODS All subjects completed the SHI and the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Head & Neck module (QLQ-H&N35). Twenty-nine patients...

BACKGROUND The purpose of this study was to compare total laryngectomy versus concurrent chemoradiotherapy (CRT) for functional and long-term quality of life (QOL) outcomes in patients with pharyngolaryngeal carcinoma. METHODS Among 145 patients treated for advanced pharyngolaryngeal cancer by CRT or total laryngectomy between 2000 and 2008, 47 patients who had completed treatment for >1 year...
