In the last decade, many efforts have been made to characterize anatomic changes of head and neck organs at risk (OARs) and the dosimetric consequences during radiotherapy. This review was undertaken to provide an overview of the magnitude and frequency of these effects, and to investigate whether we could find criteria to identify head and neck cancer patients who may benefit from adaptive rad...
ID: 4975 Title: Modeling Dose Delivery Accuracy of IMRT Head-and-Neck Cancer Treatment Purpose: To evaluate the impact of internal organ variations on IMRT treatments of head-and-neck cancers using different daily alignment techniques. Method and Materials: Eleven head-and-neck cancer patients were imaged twice weekly during their course of treatment (141 CT scans total) using an integrated CT-...
Background & Objective: Lipoma (a benign tumor composed of adipose tissue) is the most common benign mesenchymal tumors in soft tissue but it is very rare in the parotid gland. Case: We reported a 54 years old man with parotid gland lipoma. Parotid gland lipoma usually originates from the superficial lobe. Superficial parotidectomy has been considered as the choice method of the treatment. ...
بررسی تآثیر کورکومین بر بیان آکواپورین5 در سلول های سرطانی روده بزرگ انسان(ht-29) سرطان روده بزرگ جزو بیماری های خطرناک بوده و از نظر شیوع سومین سرطان شایع و دومین علت مرگ ومیر ناشی از سرطان در جهان محسوب می شود. خطرابتلا به این سرطان تحت تاثیر دو عامل محیطی وفاکتورهای ژنتیکی می باشد. آکواپورین ها، پروتئین های کانال آبی بوده که نقش مهمی را در انتقال آب در بافتهای اندوتلیالی و اپی تلیالی بر عهد...
AIM To retrospectively analyze the epidemiological, clinical and pathological data of parotid tumors. MATERIAL AND METHODS Reassessment of the histologic diagnosis of parotid tumor in the patients admitted to the Oral and Maxillofacial Surgery Unit of the Iasi "Sf. Spiridon" University Emergency Hospital during 2009-2013. Data on gender, age, place of residence, location, size, surgical proce...
BACKGROUND The purpose of this study was to identify factors predictive of outcome in patients undergoing temporal bone resection (TBR) for head and neck cancer. METHODS This was a retrospective study of 72 patients undergoing TBR. Factors associated with survival and recurrence were identified on multivariable regression. RESULTS Most tumors were epithelial (81%), commonly (69%) involving ...
BACKGROUND To describe long-term changes in time of quality of life (QOL) and the relation with parotid salivary output in patients with head-and-neck cancer treated with radiotherapy. METHODS Forty-four patients completed the EORTC-QLQ-C30(+3) and the EORTC-QLQ-H&N35 questionnaires before treatment, 6 weeks, 6 months, 12 months, and at least 3.5 years after treatment. At the same time points...
No conventional therapy exists for salivary hypofunction in surviving head and neck cancer patients with Radiation Therapy Oncology Group late grade 2-3 toxicity. We conducted a phase I clinical trial to test the safety and biologic efficacy of serotype 5, adenoviral-mediated aquaporin-1 cDNA transfer to a single previously irradiated parotid gland in 11 subjects using an open label, single-dos...
OBJECTIVES/HYPOTHESIS This study aims to evaluate the pattern of nodal metastasis to level V in parotid cancer and to examine the clinical value of level V neck dissection (LVND). STUDY DESIGN Retrospective cohort study. METHODS Retrospective chart review of 86 patients (47 N0 nodal metastasis [N0] neck and 39 positive nodal metastasis [N(+) ] neck) who received parotidectomy and neck disse...
