Breast Cancer Metastasis to the Parotid: A Case Report with Imaging Findings.

BACKGROUND Metastasis to the salivary gland is rare, with the parotid being the most commonly involved site among the salivary glands. Breast cancer metastasis to the parotid gland has been rarely reported in the literature, and relatively few case reports have described the imaging findings. CASE REPORT A 59-year-old woman presented with a recently growing mass in the left parotid gland.

Serum Calcitonin-Negative Medullary Thyroid Carcinoma: A Case Series of 19 Patients in a Single Center.

Introduction: Medullary thyroid carcinoma (MTC) is a rare cancer that accounts for 5% of thyroid cancers. Serum calcitonin is a good biomarker for MTC, which is used for diagnosis, prognosis, and monitoring of recurrence. Calcitonin-negative MTC (CNMTC) is rare but confounds diagnostic and prognostic directions.

Modified method to improve the diagnostic efficiency of F-FDG PET/CT in regional lymph node metastasis of esophageal squamous cell carcinoma.

Background: Regional lymph node (LN) metastasis is a significant factor influencing the treatment choice of esophageal squamous cell carcinoma (ESCC). The performance PET/CT as an imaging evaluation method for regional LNs in ESCC, is unsatisfactory due to the lack of logical criterion. We explored how a modified criterion improved the diagnostic value of F-FDG PET/CT in regional LN metastasis.

Concomitant malignancies in the neck: follicular dendritic cell sarcoma; a rare tumour presenting as a right-sided neck nodal mass and papillary carcinoma thyroid.

Follicular dendritic cell sarcoma is a rare low-grade sarcoma of mesenchymal origin. It involves the lymph nodes more commonly and rarely extranodal sites. The most common lymph node is cervical and usually presents as a painless asymptomatic mass.

Nerve-sparing robotic-assisted radical prostatectomy: how I do it after 15.000 cases.

Introduction: Over the years, since Binder and Kramer described the first Robotic-assisted Radical Prostatectomy (RARP) in 2000, different Nerve-sparing (NS) techniques have been proposed by several authors (1). However, even with the robotic surgery advantages, functional outcomes following RARP, especially erection recovery, still challenge surgeons and patients (2, 3). In this scenario, we have described different ways and grades of neurovascular bundle preservation (NVB) using the prostatic artery as a landmark until our most recent technique with lateral prostatic fascia preservation and modified apical dissection (4-6).

Anatomical Variations and Relationships of the Infratemporal Fossa: Foundation of a Novel Endonasal Approach to the Foramen Ovale.

 Access to the infratemporal fossa (ITF) is complicated by its complex neurovascular relationships. In addition, copious bleeding from the pterygoid plexus adds to surgical challenge. This study aims to detail the anatomical relationships among the internal maxillary artery (IMA), pterygoid plexus, V and pterygoid muscles in ITF.

Measurement of thyroglobulin level in lateral neck lymph node fine needle aspiration washout fluid in papillary thyroid cancer.

Background: Thyroglobulin (Tg) level of fine needle aspiration (FNA) washout fluid (FNA-Tg) is useful to detect cervical lymph node (LN) metastasis in patients with papillary thyroid cancer (PTC). The objective of this study was to determine appropriate cutoff values of serum Tg (S-Tg) and FNA-Tg levels for diagnosis of lateral neck LN metastasis and investigate their diagnostic performance.

Methods: A total of 169 patients with PTC who underwent modified radical neck dissection (mRND) were retrospectively reviewed at Seoul St.

The Role of IONM in Reducing the Occurrence of Shoulder Syndrome Following Lateral Neck Dissection for Thyroid Cancer.

Lateral neck dissection (LND) leads to a significant morbidity involving accessory nerve injury. Modified radical neck dissection (MRND) aims at preservation of the accessory nerve, but patients often present with negative functional outcomes after surgery. The role of neuromonitoring (IONM) in the prevention of shoulder syndrome has not yet been defined in comparison to nerve visualization only.

Surgical refinement of the purse-string suture for skin and soft tissue defects of the head and neck.

Background: The purse-string suture (PSS) is a simple and rapid wound closure method that results in minimal scarring. It has been used to treat circular or oval skin defects caused by tumor excision or trauma. However, due to obscurity, it is not widely used, especially for the head and neck.

Development and Validation of a Modified Pathologic Nodal Classification System for Cutaneous Melanoma.

Importance: Given the evolving patterns of lymph node evaluation for cutaneous melanoma, it is unclear whether the current nodal classification system will continue to accurately reflect prognosis in the modern era. Existing nodal staging for cutaneous melanoma was developed primarily for patients undergoing completion lymph node dissection (CLND) for node-positive disease and does not produce groups with continuously increasing mortality.

Objective: To develop and validate a modified nodal classification system for cutaneous melanoma.

Differentiated Thyroid Cancer in Children and Adolescents: Long Term Outcome and Risk Factors for Persistent Disease.

Pediatric differentiated thyroid cancer (P-DTC) frequently presents with advanced disease. The study aim was to evaluate the outcome of P-DTC and a modified 2015 American Thyroid Association risk classification (ATA-R). A retrospective study of consecutive P-DTC patients was performed.

Impact of Nutritional Status on Survival in Head and Neck Cancer Patients After Total Laryngectomy.

Malnutrition is an important prognostic indicator of laryngeal squamous cell carcinoma. Retrospective study with head and neck cancer patients who underwent total laryngectomy. 243 patients of both sex were evaluated.

Clipless Robotic-assisted Radical Prostatectomy and Impact on Outcomes.

Background: The use of surgical clips for athermal dissection of the lateral prostatic pedicles and ligation during pelvic lymph node dissection (PLND) while performing robotic-assisted radical prostatectomy (RARP) has been the gold standard. Clips are used to prevent thermal injury of the unmyelinated nerve fibers and lymphceles, respectively.

Objective: To compare oncological and functional outcomes of a new technique of clipless, lateral pedicle control and PLND with RARP with bipolar energy (RARP-bi) versus the standard RARP technique with clips (RARP-c).

Case Report: Modified Thoracoscopic-Assisted Cervical Resection for Retrosternal Goiter.

The treatment of choice for retrosternal goiters (RSG) is surgical resection to relieve symptoms and rule out malignancy. Although the majority of RSG can be removed by a cervical approach only, an extracervical approach (e.g.

Supracricoid Partial Laryngectomy With and Without Neoadjuvant Chemotherapy in Glottic Cancer.

Objectives/hypothesis: To demonstrate that a group of patients who are not considered candidates for organ preservation can achieve organ preservation through neoadjuvant chemotherapy + surgery and to determine if there are differences regarding organ preservation, disease-free survival (DFS), overall survival (OS), and cancer-specific survival (CSS) after comparing such group with another one undergoing standard treatment.

Methods: Patients with laryngeal cancer were retrospectively analyzed and divided into two groups. Group A included patients who were initially treated with supracricoid laryngectomy.

Primary acinic cell carcinoma of mandible, report of a case and literature review.

Introduction And Importance: Acinic cell carcinoma (ACC) is a rare low-grade salivary gland malignancy that accounts for approximately 17% of all salivary gland malignancies. The most common site affected by ACC is the parotid gland followed by the submandibular glands, minor salivary glands, and sublingual glands. Also, it could hardly be observed in unusual sites such as the jaw bones.

Incidence of metastasis to level V lymph nodes in clinically positive necks among Sri Lankan patients with oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) remains the most common cancer among males in Sri Lanka. Metastasis to neck is a crucial prognostic factor. A modified radical/radical neck dissection including levels I -V, was performed in patients with OSCC who had a clinically positive neck (cN+).

Modified Transpterygoid Approach to Sphenoid Meningoencephaloceles: A Shorter Run for a Longer Slide.

Objectives: Cerebrospinal fluid (CSF) leaks and meningoencephaloceles originating in the lateral recess of the sphenoid sinus can be challenging. The traditional transpterygoid approach through the pterygopalatine fossa (PPF) is time consuming and places important structures at risk, which can lead to significant morbidity. We report a multi-institutional experience using a simplified, endoscopic modified transpterygoid approach (MTPA), which spares the PPF contents in the management of lateral sphenoid sinus meningoencephaloceles and CSF leaks.

Neck dissection and trans oral robotic surgery for oropharyngeal squamous cell carcinoma.

Objective: Trans Oral Robotic Surgery (TORS) is a modality in the management of oropharyngeal squamous cell carcinoma(OPSCC). This study was planned to determine whether Selective Neck Dissection (SND) is oncological safe procedure even in patients with lymph node metastases.

Methods: OPSCC patients were divided into Modified Radical Neck Dissection (MRND) and SND groups.

Impact of Neck Dissection in Head and Neck Squamous Cell Carcinomas of Unknown Primary.

Purpose: Management of head and neck cancers of unknown primary (HNCUP) combines neck dissection (ND) and radiotherapy, with or without chemotherapy. The prognostic value of ND has hardly been studied in HNCUP.

Methods: A retrospective multicentric study assessed the impact of ND extent (adenectomy, selective ND, radical/radical-modified ND) on nodal relapse, progression-free survival (PFS) or survival, taking into account nodal stage.

Lymph Node Yield and Ratio in Selective and Modified Radical Neck Dissection in Head and Neck Cancer-Impact on Oncological Outcome.

: Lymph node metastases are associated with poor prognosis in head and neck squamous cell carcinoma (HNSCC). Neck dissection (ND) is often performed prior to or after (chemo)radiation (CRT) and is an integral part of HNSCC treatment strategies. The impact of CRT delivered prior to ND on lymph node yield (LNY) and lymph node ratio (LNR) has not been comprehensively investigated.
