Head & neck melanoma: A 22-year experience of recurrence following sentinel lymph node biopsy.

Objective: To examine the clinicopathologic factors that contribute to regional and distant recurrence in intermediate to high risk head and neck melanoma patients after sentinel lymph node biopsy (SLNB).

Methods: This study is a retrospective review from an academic tertiary care center. Patients treated with SLNB for head and neck melanoma from 1997 to 2019 were reviewed and characterized by sentinel lymph node (SLN) status.

A Tool to Locate Parathyroid Glands Using Dynamic Optical Contrast Imaging.

Objectives/hypothesis: Identification of parathyroid glands and adjacent tissues intraoperatively can be quite challenging because of their small size, variable locations, and indistinct external features. The objective of this study is to test the efficacy of the dynamic optical contrast imaging (DOCI) technique as a tool in specifically differentiating parathyroid tissue and adjacent structures, facilitating efficient and reliable tissue differentiation.

Study Design: Prospective study.

Paneled Saphenous Vein Grafts Compared to Internal Jugular Vein Grafts in Venous Reconstruction after Pancreaticoduodenectomy.

Background: Venous resection during pancreaticoduodenectomy for the excision of pancreatic cancer allows for a more complete resection with negative margins, which increases survival. When the resected vein is greater than 3 cm, reconstruction with an interposition graft is recommended. However, consensus regarding the optimal venous conduit has not been reached.

Vibroacoustographic System for Tumor Identification.

Oral and head and neck squamous cell carcinoma (OSCC) is the sixth most common cancer worldwide. The primary management of OSCC relies on complete surgical resection of the tumor. Margin-free resection, however, is difficult given the devastating effects of aggressive surgery.

Detection of surgical margins in oral cavity cancer: the role of dynamic optical contrast imaging.

Purpose Of Review: The quantity of tissue removed during an oncologic surgical procedure is not standardized and there are numerous reports of local recurrence despite histologically adequate resection margins. The oral cavity is one of the sites in the head and neck with high chances of recurrence following negative margins. To address this need, this article reviews the recent applications of Dynamic Optical Contrast Imaging (DOCI) towards both oral screening and the intraoperative evaluation of tumor margins in head and neck surgery.

Use of a Novel Polymer in an Animal Model of Head and Neck Squamous Cell Carcinoma.

Objective To evaluate the adverse effects and therapeutic efficacy of our biocompatible polymer platform delivering targeted local therapy of cytokine CCL21 and cisplatin in a partially resected xenograft animal model of head and neck squamous cell carcinoma. In addition, to evaluate the efficacy of cotreatment with radiotherapy and assess the biocompatibility of the cisplatin-eluting polymer in the murine neck. Study Design Experimental animal study.

Assessment of risk of bias in translational science.

Risk of bias in translational medicine may take one of three forms: A. a systematic error of methodology as it pertains to measurement or sampling (e.g.

Prognostication of prostate cancer based on TOP2A protein and gene assessment: TOP2A in prostate cancer.

Background: TOP2A encodes for topoisomerase IIα, a nuclear enzyme that controls DNA topological structure and cell cycle progression. This enzyme is a marker of cell proliferation in normal and neoplastic tissues; however, little information is available about its expression in prostate cancer (PCa).

Methods: Immunohistochemistry (IHC) was automated using mouse monoclonal antibody against TOP2A (clone SWT3D1; DAKO, Carpenteria, CA, USA) at dilution 1:800 and Flex Plus detection system in autostainer 48Ultra (DAKO).
