Prognosis of cancers with lymph node metastasis is known to be very poor; however, it is still controversial whether metastatic potential can be evaluated by expression profiles of primary tumors. Therefore, to address this issue, we compared gene expression profiles of 24 esophageal squamous cell carcinomas (ESCCs) with extensive lymph node metastasis and 11 ESCCs with no metastatic lymph node...
BACKGROUND Lymph node metastasis is a significant prognostic factor in intrahepatic cholangiocarcinoma. This study was aimed at investigating lymph node metastasis in intrahepatic cholangiocarcinoma and to examine whether the extent of metastasis affects outcomes after surgery. METHODS From 1980 through 1996, 70 patients with intrahepatic cholangiocarcinoma underwent hepatectomy, with a 50% c...
Malignant pleural mesothelioma (MPM) is a rare tumor with disastrous evolution. The prognostic value of nodal involvement is still debated. We analyzed the impact of nodal involvement on overall survival (OS) in patients treated by multimodal therapy including extra pleural pneumonectomy (EPP). We evaluated the role, as a prognostic factor, of the metastatic lymph node ratio (LNR), correspondin...
background & objectives: colon cancer is currently of high incidence and mortality rate. identifying the factors influencing its prognosis can be very beneficial to its clinical treatment. recent studies have shown that lymph nodes ratio can be considered as an important prognostic factor. the aim of the present study is to investigate the effect of this factor on the prognosis of the patie...
PURPOSE To evaluate the accuracy of axillary ultrasound (AUS) in detecting nodal metastasis in patients with early-stage breast cancer and to identify AUS features with high predictive power. MATERIALS AND METHODS Prospective single-center preliminary study in 105 patients with a primary diagnosis of breast cancer and clinically negative axilla. AUS was performed using a 12 MHz linear-array t...
Lymph nodes posterior to the right recurrent laryngeal nerve (LN-prRLN) are common sites of nodal recurrence after the resection of papillary thyroid carcinoma (PTC). However, the indication for LN-prRLN dissection remains debatable. We therefore studied the relationships between LN-prRLN metastasis and the clinicopathological characteristics in 306 patients with right or bilateral PTC who unde...
BACKGROUND Preoperative diagnosis of lymph node metastasis is often difficult. A number of different criteria have been advocated in the literature, however, an optimal criterion has not yet been determined in patients with rectal carcinoma. PATIENTS AND METHODS Fifty-one patients, undergoing radical surgery with total mesorectal excision, were examined with reference to regional lymph node s...
