BACKGROUND Accurate evaluation of lymph node metastasis in bladder cancer (BCa) is important for disease staging, treatment selection, and prognosis prediction. In this study, we aimed to evaluate the diagnostic accuracy of computed tomography (CT) and magnetic resonance imaging (MRI) for metastatic lymph nodes in BCa and establish criteria of imaging diagnosis. METHODS We retrospectively ass...

background: the sentinel lymph node (sln) is defined as the first chain node in the lymphatic basin that receives primary lymphatic flow. if the sln is negative for metastatic disease, then other nodes are expected to be disease-free. sln techniques have been extensively applied in the staging and treatment of many tumors, including melanoma, breast and vulvar cancers. this study aims to evalua...

hepatocellular carcinoma (hcc) is the most common, malignant tumor of the liver. hepatocellular carcinoma (hcc) commonly metastasizes to the lungs, abdominal lymph nodes, adrenal glands, or bones. distant lymph node metastases are rare in hepatocellular carcinoma. a 49-year-old male patient presented with right sided neck mass. on examination there was right cervical lymphadenopathy and hepatom...

BACKGROUND The incidence of the esophagogastric junction cancer is growing rapidly. The purpose of this study is to clarify the outcome of the ratio between metastatic and examined lymph nodes in esophagogastric junction cancer patients with or without 7 examined lymph nodes. METHODS A total of 3,481 patients who underwent operation are identified from the Surveillance, Epidemiology, and End ...

AIM To investigate whether the recommendation to remove 15 lymph nodes that is used in the staging system is necessary to assess gastric cancer progression and to evaluate whether our metastatic lymph node ratio dividing method, adapted from the AJCC's (American Joint Committee on Cancer) 7(th) TNM staging system, is helpful for the patients with fewer than 15 harvested lymph nodes. METHODS W...

Background: Intra-operative molecular diagnostic assays are currently used for the detection of lymph node metastases. The objective of this study was to find new biomarkers to improve diagnostic accuracy in the detection of metastatic axillary lymph nodes in breast cancer patients. Methods: We applied an absolute quantitative real-time RT-PCR to quantitate the expression of CK19, KLK11, and CL...
