Background: The purpose of this study was to present our focus on the lymph node status in the central compartment and evaluate the relevant factors and disease recurrence.
Methods: Between January 2004 and December 2009, 1040 patients were diagnosed with papillary thyroid carcinoma (PTC) and underwent surgery.
Results: The number of metastatic lymph nodes was a significant predictor for recurrence conferring a hazard ratio of 1.36 (confidence interval = 1.103-1.680; p = .004). The receiver operating characteristic (ROC) curve was calculated to determine the cutoff number of lymph nodes that predicted recurrence with the highest sensitivity and specificity (area under the ROC curve, 0.794; SE, 0.077; p = .001). The sensitivity/specificity of >3 metastatic lymph nodes for predicting recurrence was 63.6%/77.0%, respectively.
Conclusion: The number of metastatic lymph nodes in the central compartment was a statistical significant predictive factor associated with disease recurrence. Further study is required to confirm the relationship between the number of lymph nodes and disease recurrence. © 2015 Wiley Periodicals, Inc. Head Neck 38: E1172-E1176, 2016.

Lymph node sampling with endoscopic ultrasound fine needle aspiration (EUS-FNA) may affect treatment options for biliary tract cancers. Our aim is to clarify its utility and clinical significance and the factors associated with FNA cytology positivity. Seventy-one consecutive patients with biliary tract cancer who underwent EUS-FNA to diagnose lymphadenopathies from April 2012 to July 2021 were enrolled retrospectively.

Background: Most patients undergoing pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC) develop recurrence. No previous studies have investigated predictors of local-only recurrence following PD for PDAC. Our study aimed to determine timing, pattern and predictors of any-site and local-only recurrence following PD for PDAC.

Objectives: The aim of this prospective study was to assess the association between methylene blue staining pattern and the presence of histologic nodal metastasis in dogs with low-grade mast cell tumour in low-resource settings for the efficient diagnosis of lymphatic spread.
Methods: Dogs with a single, cytologically low-grade mast cell tumour and no documented distant metastases were prospectively included and underwent surgery. Along with primary mast cell tumour removal, intraoperative sentinel lymph node mapping with peritumoral mast cell tumour injection and regional lymph node excision, regardless of whether blue dye was visible in the lymph node, were performed.
Introduction: Esophageal squamous cell carcinoma (ESCC) has one of the poorest cancer prognosis rates; there is an urgent need to develop new drug therapies and biomarkers. CD63, a tetraspanin protein and well-known exosomal marker, is implicated in cancer progression; however, the significance of CD63 expression in ESCC remains unclear. Herein, we report the significance of CD63 expression by analyzing ESCC patient samples and ESCC cell lines.

Studying the human immune system in vivo is challenging and often not possible. Therefore, most human immunology studies have been predominantly confined to peripheral blood analyses, which by themselves have inherent limitations, as many immune reactions take place within tissues. For example, potent antibody responses that contribute to fighting infections and provide protection following vaccination require cellular interactions between B cells and T cells in specialized micro-anatomical structures called germinal centers, which are found in secondary lymphoid organs such as spleen, lymph nodes, and tonsils.
