P S Heng, M Irfan
Hypopharyngeal cancer (HPC) is generally a rare head and neck malignancy. There are differing clinical presentations depending on the subsite location of primary tumour. Advanced HPC will have neck node metastasis particularly upper jugulodigastric nodes. We report a patient with postcricoid tumour who presented with anterior huge neck swelling mimic thyroid mass. The patient first presented to the General Surgical Unit for management of presumed thyroid lesion. She was diagnosed post-cricoid squamous cell carcinoma when further assessed by otorhinolaryngologist...

OBJECTIVE: Papillary thyroid cancer (PTC) could behave differently in prepubertal than in pubertal children and between children and adults. BRAF gene activating mutations may associate with PTC by creating aberrant activation. We aimed to evaluate clinicopathological characteristics of PTC patients with emphasis on the pubertal status and investigate the association of BRAFV600E mutation with disease characteristics. METHODS: Medical records of 75 patients with PTC were reviewed retrospectively...

Background: Knowing esophageal tumors behavior in relationship to lymph node involvement, distant metastases and local tumor invasion is of paramount importance for the best esophageal tumors management. Aim: To describe lymph node involvement, distant metastases, and local tumor invasion in esophageal carcinoma, according to tumor topography and histology.

BACKGROUND: Salivary duct carcinoma (SDC) is a high-grade salivary gland malignancy that is associated with an aggressive clinical behavior and poor prognosis. Herein, we report on a long surviving case of SDC of the minor salivary gland with multiple lymph node metastases (LNMs). CASE PRESENTATION: An 83-year-old woman presented with a history of lymphadenopathy in the right side of the neck and recent onset and rapid growth of a mass in the right buccal region...

Mucosal melanomas represent a rare entity with different risk factors and molecular features compared to cutaneous melanomas. They arise most commonly from mucosal surfaces in the head/neck region, the female genital tract (FGT) and the anorectal region. The aim of this study was to evaluate clinics, prognosis, and treatment options of patients with mucosal melanoma, in particular with regard to different primary sites.We retrospectively analyzed 75 patients with mucosal melanomas diagnosed in the years 1993 to 2015 in our department...

AIM: Lymph node yield (LNY) is a valid marker of prognosis in oral cancer. Precise estimation of LNY in Indian patients with T3/T4 gingivobuccal sulcus squamous cell carcinoma (GBS-SCC) has not been well documented. Hence, the primary objective of the study was to determine the LNY in patients with T3/T4 SCC of mandibular GBS, and the secondary objective was to study the association of LNY with clinicopathological factors such as tumor thickness, histological differentiation, number of positive nodes, and extracapsular spread (ECS)...

CONTEXT: Medullary thyroid carcinomas (MTCs) complicated by ectopic Cushing's syndrome have a poor prognosis, partially due to the difficulties to control hypercortisolism by adrenal blocking drugs. Recent reports (including the initial follow-up of this patient) have suggested that tyrosine kinase inhibitors (TKIs) may be a therapeutic option due to an antisecretory action on ACTH. However, there is a lack of long-term follow-up studies. CASE DESCRIPTION: We report the case of a 58 year-old man with a MTC-related Cushing's syndrome resistant to a combination of several anticortisolic drugs...

BACKGROUND: Sentinel lymph node biopsy (SLNB) for head and neck melanoma is challenging due to unpredictable drainage. We sought to determine the frequency of drainage to multiple lymphatic basins and asked if this was associated with prognosis in a large, single-center cohort. METHODS: We queried patients diagnosed with head and neck melanomas who had a SLNB performed from January 1998 to April 2016. Demographic and clinical characteristics were compared using Student's t test, Pearson chi-square analysis, log-rank test, Wilcoxon-Mann-Whitney test, and Kaplan-Meier curves...

OBJECTIVE: No clear consensus exists regarding the optimal interval and frequency of follow-up PET-CT in head and neck squamous cell carcinoma (HNSCC) patients treated with chemoradiotherapy (CRT). Here we sought to clarify whether the changes in the maximum standardized uptake value (ΔSUVmax) may be a valid parameter to help decision-making for surveillance management after CRT. METHODS: Forty patients underwent PET-CT at pretreatment and 3 months after CRT. Patients were followed by sequential PET-CT for 2 years after CRT...

BACKGROUND: Nasopharyngeal carcinoma (NPC) is a malignant epithelial carcinoma of the head and neck with strong ability of invasion and metastasis. Our previous study indicated that miR-324-3p, as a tumor-suppressive factor, could regulate radioresistance of NPC cells by targeting WNT2B. The purpose of this study is to investigate the role of miR-324-3p on migration and invasion in NPC cells. METHODS: Quantitative real time PCR was applied to measure the expression level of miR-324-3p and WNT2B mRNA in both cells and tissues, and the expression level of WNT2B protein was determined by western blotting...

The goals of this retrospective cohort study were to compare the results of clinical and pathological TNM staging in patients with laryngeal squamous cell carcinoma and to determine the impact of the discordance on prognosis and treatment results. A total of 124 patients with laryngeal cancer, primarily indicated for surgical treatment, were enrolled. The concordance or discordance between the clinical and pathological staging was compared with the frequency of cancer relapse and disease-specific survival. Other potential prognostic factors, like age, the stage and location of the primary tumor, the status of neck lymph nodes, histological margins, and an indication for postoperative radiotherapy, were also evaluated...

BACKGROUND: The aim of this study was to compare the short-term outcomes and three-year survival between dual-incision esophagectomy (DIE) and total minimally invasive McKeown esophagectomy (MIME) for esophageal cancer patients with negative upper mediastinal lymph nodes requiring esophagectomy and neck anastomosis. METHODS: One hundred and fifty patients underwent DIE, while 361 patients received total MIME. Perioperative outcomes and three-year survival were compared in unmatched and propensity score matched data between two groups...

PURPOSE: Minimal access thyroidectomy, using various techniques, is widely known, but respective data on thyroidectomy for thyroid cancer with lymphadenectomy is scarce. The present study aims to evaluate the feasability of extended subplatysmal dissection in combination with a small incision ("mobile window" technique). METHODS: A retrospective study was performed analysing data from 93 patients. All patients suffered from thyroid carcinoma and underwent (total) thyroidectomy, bilateral cervico-central (levels VI and VII) and functional lateral neck dissection (levels II to V) on the side of the malignancy...

Methods Online survey of surgeon members of the American Head and Neck Society (AHNS). Survey investigated respondents' demographic information, degree of surgical experience, ND technique preferences. Results In our study, 283 out of 1,010 (28%) AHNS surgeon members with a mean age of 50...

Y Ge, P Keall, P Poulsen
PURPOSE: Multiple targets with large intrafraction independent motion are often involved in advanced prostate, lung, abdominal, and head and neck cancer radiotherapy. Current standard of care treats these with the originally planned fields, jeopardizing the treatment outcomes. A real-time multi-leaf collimator (MLC) tracking method has been developed to address this problem for the first time. This study evaluates the geometric uncertainty of the multi-target tracking method. METHODS: Four treatment scenarios are simulated based on a prostate IMAT plan to treat a moving prostate target and static pelvic node target: 1) real-time multi-target MLC tracking; 2) real-time prostate-only MLC tracking; 3) correcting for prostate interfraction motion at setup only; and 4) no motion correction...

PURPOSE: To investigate an approach of automatically recognizing anatomical sites and imaging views (the orientation of the image acquisition) in 2D X-ray images. METHODS: A hierarchical (binary tree) multiclass recognition model was developed to recognize the treatment sites and views in x-ray images. From top to bottom of the tree, the treatment sites are grouped hierarchically from more general to more specific. Each node in the hierarchical model was designed to assign images to one of two categories of anatomical sites...
