OBJECTIVE This study aims to investigate the correlations between rapidly accelerated fibrosarcoma/mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase signaling pathway and clinicopathological features and prognosis for patients with breast cancer having axillary lymph node metastasis. METHODS A total of 118 breast cancer tissues with axillary lymph node metast...

Three-field lymph node dissection has been widely used to treat thoracic esophageal cancer, but is very invasive and can cause serious complications. Whether cervical lymph node dissection should be performed in all patients with thoracic esophageal cancer remains controversial. We pathologically examined the recurrent nerve lymph nodes during surgery in patients with thoracic esophageal cancer...

Vascular endothelial growth factor receptor (VEGFR)-3 is considered to be associated with lymphangiogenesis. The aim of the present study was to identify the clinical significance of VEGFR-3 expression and lymph node metastasis in patients with non-small-cell lung cancer (NSCLC). Lung tumor tissue samples and 196 lymph nodes from 52 patients with NSCLC were analyzed. In addition, lung tissue sa...

This retrospective study aimed to evaluate whether ultrasound texture analysis is useful to predict lymph node metastasis in patients with papillary thyroid microcarcinoma (PTMC). This study was approved by the Institutional Review Board, and the need to obtain informed consent was waived. Between May and July 2013, 361 patients (mean age, 43.8 ± 11.3 years; range, 16-72 years) who underwent st...

Colorectal carcinoma is a common malignancy in India as well as in world. Inspite of its high metastasizing ability to various organs and lymph node, orbital metastasis is exceptional. Very few cases have been reported in the world literature. We report orbital metastasis in a case of moderately differentiated rectal adenocarcinoma in a 58-year male patient from India in 2015. We want to focus ...

background: breast cancer is the most prevalent malignancy in women and there are many possible reasons for its occurrence. one important issue in different kinds of cancers is the spreading of cancerous cells to other tissues (metastasis). therefore, we have investigated the factors associated with the prediction of metastasis of breast cancer with data mining tools. methods: this study is a c...

BACKGROUND We performed this retrospective study to identify predictors of right paraesophageal lymph node metastasis, and reviewed previous studies related to this topic. METHODS Between June 2005 and March 2015, 1107 patients were diagnosed with papillary thyroid carcinoma and underwent surgery at Pusan National University Hospital. RESULTS Right paraesophageal lymph node metastasis was o...

Colorectal carcinoma is the second biggest cancer responsible for mortality. Lung metastasis is the commonest, following the liver. It is not uncommon to perform pulmonary metastasectomy and identify mediastinal metastasis. Previous studies have identified incidental lymph node involvement following routine mediastinal lymph node clearance in 20-50% of cases. However, solitary intrathoracic lym...
