BACKGROUND A number of studies had reported the association between tumor necrosis factor-alpha (TNF-α) gene polymorphisms and head and neck cancer (HNC) risk. However, the results remained controversial. Therefore, we performed a meta-analysis to derive a more precise evaluation of the association between TNF-α-308G/A polymorphism and overall HNC risk and evaluated influence of cancer types an...
In treating head and neck cancer (HNC), the objectives are provided for best functional results and minimal risk of serious complications. The choice of appropriate management depends primarily on specific site and stage of primary tumor at diagnosis. Radiation therapy (RT) with or without concomitant chemotherapy represents a classical treatment option. In this review, we provide an update of ...
Background: Long-term computer use as an ergonomics risk factor can generate musculoskeletal disorders, especially in the neck. This study aimed to investigate the effect of a self-management exercises intervention on both neck pain, and head and neck angles among university employees in 2021. Materials & Methods: This experimental study was performed on 85 university staff (experimental group...
The use of PET/CT as an adjunct in radiotherapy planning is an attractive option in head and neck cancer (HNC) for several reasons. First, with potentially better identification of the disease extent, i.e., staging, the risk of geographical miss of radiation delivery to the gross tumor volume is reduced. Second, in characterizing the biological behavior of the disease for example, areas of hypo...
OBJECTIVE This study aims to evaluate the impact and potential prognostic roles of the pre- and post-treatment Glasgow prognostic score (GPS) and the change thereof in patients with advanced head and neck cancer undergoing concurrent chemoradiotherapy (CCRT). METHODS We collected GPS and clinicopathological data of 139 stage III, IVA, and IVB head and neck cancer patients who underwent CCRT b...
Salvage therapy in head and neck cancer (HNC) is a controversy issue and the literature is scarce regarding the use of interstitial high-dose rate brachytherapy (I-HDR) in HNC. We evaluated the long-term results of a treatment policy combining salvage surgery and I-HDR for cervical recurrences of HNC. Charts of 21 patients treated from 1994 to 2004 were reviewed. The crude local control rate fo...
BACKGROUND This study describes the results of elective irradiation in the N0 neck and tries to identify prognostic factors for regional recurrence. MATERIALS AND METHODS Between 1985 and 2000, 785 cN0 or pN0 necks were treated with elective nodal irradiation in 619 head and neck squamous cell carcinoma patients. RESULTS Regional control at 3 years was 94% in the cN0 (nondissected) neck com...
BACKGROUND The aim of the study was to evaluate and compare the efficacy, tolerability and toxicity of three palliative radiotherapy (RT) schedules in locally advanced head and neck carcinoma (LAHNC), i.e. Quad Shot schedule, Christie schedule and conventional palliative schedule. METHODS The patients were randomly divided into three groups of 30 each. Group I patients were planned for 14.8 G...
Adenosquamous carcinoma is a rare distinct clinicopathological entity characterized histopathologically by components of both squamous cell carcinoma and adenocarcinoma [1]. This type of carcinoma is described in a variety of sites, including lung, pancreas, and uterine cervix, while the head and neck region is a relatively rare origin for this type of tumor [1]. The existence of adenosquamous ...
Previous studies have suggested that the HIF transcription factors can both activate and inhibit gene expression. Here we show that HIF1 regulates the expression of mir-210 in a variety of tumor types through a hypoxia-responsive element. Expression analysis in primary head and neck tumor samples indicates that mir-210 may serve as an in vivo marker for tumor hypoxia. By Argonaute protein immun...
