Comparing the Efficacy of CT, MRI, PET-CT, and US in the Detection of Cervical Lymph Node Metastases in Head and Neck Squamous Cell Carcinoma with Clinically Negative Neck Lymph Node: A Systematic Review and Meta-Analysis.

Traditional imaging techniques have limited efficacy in detecting occult cervical lymph node (LN) metastases in head and neck squamous cell carcinoma (HNSCC). Positron emission tomography/computed tomography (PET-CT) has demonstrated potential for assessing HNSCC, but the literature on its efficacy for detecting cervical LN metastases is scarce and exhibits varied outcomes, hindering comparisons. To compare the efficacy of CT, MRI, PET-CT, and US for detecting LN metastasis in HNSCC with clinically negative neck lymph nodes.

A new landmark for the identification of the facial nerve during parotid surgery: A cadaver study.

Objective: Precise knowledge of facial nerve anatomy is crucial for parotid surgery. Although several surgical landmarks to identify the facial nerve have been described in literature, their position is variable, inconsistent, and difficult to follow in some cases. The purpose of this study was to prove that the facial nerve trunk (FNT) is located midway between the mastoid tip (MT) and osteocartilaginous junction of the external auditory canal (EAC).

An Improved and Simplified Approach to Identify the Facial Nerve During Parotid Surgery.

Precise identification and preservation of the facial nerve is mandatory to avoid dysfunction of the facial nerve during parotidectomy. In this article, the authors are introducing a new landmark to identify the facial nerve for parotidectomy that is more protective for the facial nerve. The authors use a simple approach to predict the position of facial nerve main trunk intraoperatively without geometric calculations and a lot of landmarks.

Trends in thyroid carcinoma among thyroidectomy patients: a 12-year multicenter study.

Background: Thyroid malignancy, the most diagnosed cancer of the endocrine system, represents 2% of all malignancies worldwide. The increasing incidence of thyroid cancer has been linked to the increasing sensitivity of modern diagnostic methods which overdiagnosis small thyroid tumors.

Objectives: Assess the distribution and trends in thyroid cancer among thyroidectomy patients.

Impact of body mass index on survival outcome in patients with differentiated thyroid cancer.

Introduction: Increased body mass index is known to be associated with the high prevalence of differentiated thyroid cancers; however data on its impact on survival outcome after thyroidectomy and adjuvant therapy is scanty.

Objective: We aimed to evaluate the impact of body mass index on overall survival and disease free survival rates in patients with differentiated thyroid cancers.

Methods: Between 2000 and 2011, 209 patients with differentiated thyroid cancers (papillary, follicular, hurthle cell) were treated with thyroidectomy followed by adjuvant radioactive iodine-131 therapy and thyroid-stimulating hormone suppression.

Patterns of failure and survival in patients with nasopharyngeal carcinoma treated with intensity-modulated radiation therapy in Saudi Arabia.

Background: We aimed to investigate the patterns of failure (locoregional and distant metastasis), associated factors, and treatment outcomes in nasopharyngeal carcinoma patients treated with intensity-modulated radiation therapy (IMRT) combined with chemotherapy.

Patients And Methods: From April 2006 to December 2011, 68 nasopharyngeal carcinoma patients were treated with IMRT and chemotherapy at our hospital. Median radiation doses delivered to gross tumor volume and positive neck nodes were 66-70 Gy, 63 Gy to clinical target volume, and 50.

Comparative clinicopathological and outcome analysis of differentiated thyroid cancer in Saudi patients aged below 60 years and above 60 years.

Introduction: The aim of this study was to evaluate the treatment outcomes of differentiated thyroid cancer in Saudi patients aged above 60 years.

Materials And Methods: Comparative analysis was performed in 252 patients aged 46-60 years (Group A) and 118 patients aged above 60 years (Group B), who had thyroidectomy, radioactive iodine-131, and thyroid-stimulating hormone suppression therapy between July 2000 and December 2012. Different clinicopathological features, treatment, complications, disease-free survival, and overall survival rates were compared.

Clinicopathological features and treatment outcomes of the rare, salivary duct carcinoma of parotid gland.

Background: Salivary ductal carcinoma (SDC) of parotid gland is a rare and aggressive entity; accounting for 1-3 % of all malignant salivary gland tumors, 0.2 % of epithelial salivary gland neoplasms, 0.5 % of salivary gland carcinomas, and 1.

Adjuvant Radioactive iodine 131 ablation in papillary microcarcinoma of thyroid: Saudi Arabian experience [corrected].

Background: Papillary Microcarcinoma (PMC) of thyroid is a rare type of differentiated thyroid cancer (DTC), which according to the World Health Organization measures 1.0 cm or less. The gold standard of treatment of PMC is still controversy.

"Clinicopathological features and treatment outcomes of differentiated thyroid cancer in Saudi children and adults".

Introduction: Age is an important prognostic factor in differentiated thyroid cancer (DTC). Our aim was to evaluate differences in clinicopathological features and treatment outcomes among children and adult patients with DTC.

Materials And Methods: We studied 27 children (below 18 years) with DTC treated during the period 2000-2012 and were compared with (a) 78 adults aged 19-25 years and (b) 52 adults aged 26-30 years treated during the same period in terms of their clinicopathological features and long term treatment outcomes.

Calvarium and dura mater as delayed sites of distant metastasis from papillary thyroid carcinoma.

Background: Skull calvarium and dura mater are rare sites of distant metastasis, and mostly have been reported in lung, breast, and prostate malignancies. However, the calvarial and dural metastases from papillary thyroid cancer (PTC) are rare entities and pose diagnostic and therapeutic challenges. To date, only seven cases of calvarial metastasis with intracranial extension from PTC have been reported in literature.

Skull base metastasis from papillary thyroid carcinoma: a report of three cases.

Skull base metastasis from differentiated thyroid carcinoma, including papillary and follicular thyroid carcinoma, is a rare manifestation. Herein, we present three cases of skull base metastasis of papillary thyroid carcinoma. The mean age of the patients was 68.

Cerebellum as Initial Site of Distant Metastasis from Papillary Carcinoma of Thyroid: Review of Three Cases.

Background. The cerebellum as initial site of distant metastasis from differentiated thyroid carcinoma (DTC) including papillary (PTC) and follicular thyroid carcinoma (FTC) is rare manifestation. Case Presentations.

Nasolacrimal duct obstruction following radioactive iodine 131 therapy in differentiated thyroid cancers: review of 19 cases.

Background: Radioactive iodine 131 ((131)I) therapy has long been used in the treatment of differentiated thyroid cancers (DTC). While salivary and lacrimal glandular complications secondary to (131)I therapy are well documented, there is little in the literature addressing nasolacrimal duct obstruction (NLDO). We aimed to evaluate the frequency of (131)I therapy-acquired NLDO, its correlation to (131)I therapy doses, and the surgical treatment outcome of this rare side effect.
