RESUMEN

Upper Aerodigestive Tract Endoscopy (UATE) is recommended for initial examination of head and neck squamous cell carcinomas. Reducing delay of initial examination must be a challenge to manage head and neck cancers. We hereby describe the technic combining UATE and flexible endoscopy in a unique general anesthesia with overview of hypopharyngeal, larygeal, tracheal, esophageal, nasopharyngeal sub sites in a unique procedure with system of magnificense and to perform percutaneous gastrostomy during the same time before initiation of therapy.

RESUMEN

INTRODUCTION: Poorly differentiated primary sarcomatoid parotid malignancies are extremely rare. These tumors have not been consistently studied by morphology, immunohistochemistry, or molecular techniques. CASE PRESENTATION: We report three unusual cases of parotid gland poorly-differentiated sarcomatoid malignancy investigated by fine-needle aspiration and studied histologically, by immunohistochemistry and molecular investigations. Aspirates showed poorly specific polymorphous sarcomatoid malignancy in all cases. Histologically, all cases were polymorphous high-grade malignancies, and additionally, one case showed epithelial structures and was finally classified as salivary carcinosarcoma. Immunohistochemistry showed classical melanocytic markers negativity but positivity for PRAME, CD10, and WT1 in all three tumors and for CD56 in two tumors, which can potentially be supportive of melanocytic origin. Although not entirely specific, molecular characterization also suggested the melanocytic lineage of these tumors. CONCLUSION: Although rare, primary malignant melanoma of salivary gland was already described, but undifferentiated/dedifferentiated amelanotic forms are unknown in this localization up today. Further case reports of similar presentations are required to confirm the unequivocal primary origin of these obscure neoplasms in the parotid gland.

RESUMEN

This study aimed to assess the efficacy of utilizing the internal jugular vein (IJV) as the primary recipient site for venous anastomoses in head and neck oncological reconstruction. Patients who underwent a free flap reconstruction of the head and neck were retrospectively included. Venous anastomoses were preferentially performed less than 1 cm from the IJV, either end-to-side (EtS) on the IJV, or end-to-end (EtE) on the origin of the thyrolingofacial venous (TLF) trunk. When the pedicle length was insufficient to reach the IJV, anastomoses were performed EtE to a size-matched cervical vein. Of the 246 venous anastomoses, 216 (87.8%) were performed less than 1 cm from the IJV, including 150 EtS on the IJV (61.0%), and 66 EtE on the TLF trunk (26.8%). Thirty veins (12.1%) were anastomosed EtE on other cervical veins more than 1 cm from the IJV. Two venous thromboses occurred (0.9%) and were successfully managed after revision surgery. There was no evidence of an increased thrombosis rate in high-risk or pre-irradiated patients. These findings suggest that the internal jugular vein is safe and reliable as a first-choice recipient vessel for free flap transfers in head and neck oncological reconstruction.

RESUMEN

BACKGROUND: SMARCB1, also known as INI1, is a member of a large protein complex involved in chromatin remodeling and thus the regulation of gene expression. It is located on chromosome 22q11.2. SMARCB1 tumors have been found in various locations, including the sinonasal region, gastrointestinal tract, central nervous system (in atypical teratoid and rhabdoid tumors), and perirenal region (in malignant rhabdoid tumors) in both adults and children. CASE PRESENTATION: We describe here the first case in the literature of an INI1-deficient neck carcinoma without a primary tumor managed with surgical therapy and neck dissection in a young Caucasian woman of 29 years old, followed by chemotherapy before radiotherapy, with regional control after 18 months of follow-up. Histologic analysis showed an undifferentiated carcinoma without glandular or epidermoid differentiation. Biomolecular analysis of the tumor revealed a homozygous deletion of the SMARCB1 gene on RNA sequencing. CONCLUSION: Research of INI1 deletion should be performed for undifferentiated carcinoma of young patients because of possibilities of molecular therapies such as autophagy inhibitors or proteasome inhibitors could be used in clinical trials.

RESUMEN

INTRODUCTION: Subcricoid-hemilaryngopharyngectomy (SCHLP) with a reconstruction using a fasciocutaneous free flap armed with cartilage graft (FFACG) aims to avoid permanent tracheostomy while still maintaining the laryngopharyngeal functions. The purpose of this study is to report the outcome of this surgical approach. MATERIALS AND METHODS: Retrospective study including 17 men operated between 2001 and 2019. Specific survival rate included death caused by cancer or SCHLP complications. Complications, functional and oncological outcomes were evaluated retrospectively. RESULTS: There were no locoregional recurrences. One patient died due to inhalation pneumonia 3 years after surgery. Tracheostomy was closed in 13 patients (76.5%). Mean decannulation time was at six [1-14] months after surgery. CONCLUSION: SCHPL with FFACG could avoid total pharyngolaryngectomy with good oncologic results. However, tracheotomy is extended and deglutition recovery is long with high risk of aspirations. These complications justify that such surgery should be realized only on selected patients by experienced surgical teams. Expertise of the surgical team is critical.

RESUMEN

New optical technologies enhancing localization or assessing viability of parathyroid glands (PG) during endocrine surgery have been reported in clinical studies. These technologies could become complementary to the surgeon's eyes and may improve surgical outcomes in thyroidectomy and parathyroidectomy. Here, we conducted a systematic review focusing on PG identification and functional assessment using optical methods to enhance surgery. A systematic literature review was performed using MEDLINE and Embase database. Two authors selected studies and extracted data; qualitative analysis was performed to summarize the characteristics of reported optical tools for thyroidectomy or parathyroidectomy. Identification and vascularisation of PG during surgery were evaluated. Clinical and biochemical outcomes were appraised when reported. Studies relating to parathyroidectomy or thyroidectomy combined with autofluorescence, fluorescent methylene blue, 5-aminolevulinic acid, indocyanine green (ICG), optical coherence tomography, laser speckle contrast imaging, dynamic optical contrast imaging and Raman spectroscopy were identified with MEDLINE and Embase. We included a total of 47 relevant articles with a total of 1615 patients enrolled. Each optical technique is described and appreciated related to its surgical purpose. Autofluorescence and ICG imaging of PG are the most widely reported optical technologies for identification and assessment of vascularisation of PG. Results are mainly based on observational studies and argue for the feasibility of both techniques in endocrine surgery but prospective randomized studies have not been performed. In vivo applications are still limited for the other methods and further investigations correlating these techniques with post-operative parathormone measurements are still needed before considering these technologies in clinical practice.
