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...
PURPOSE We evaluated whether the clinicopathological factors of papillary thyroid microcarcinoma (PTMC), especially tumoe size, are associated with subcinical central lymph node metastasis. MATERIALS AND METHODS A total of 160 patients diagnosed with PTMC who underwent total thyroidectomy with bilateral central lymph node dissection were enrolled in this study. All patients were clinically ly...
BACKGROUND The indications for elective bilateral central node dissection for patients with unilateral papillary thyroid carcinoma (PTC) who are clinically node negative are still not verified. We investigated the predictive factors of lymph node metastasis and formulated guidelines for surgical extent. METHODS From 2004 to 2009, 325 patients diagnosed with unilateral PTC who had undergone to...
Background: The node classification outlined in the seventh edition of the tumor-node-metastasis (TNM) classification is based solely on the number of metastasized lymph nodes. We examined the prognostic value of apical lymph node metastasis and the additive value of incorporating apical lymph node status into a risk model based on the seventh edition. Methods: Our cohort study involved 1355 pa...
Regional lymph node status is an important prognostic indicator of tumor aggressiveness. However, early diagnosis of metastasis using intranodal pressure, at a stage when lymph node size has not changed significantly, has not been investigated. Here, we use an MXH10/Mo-lpr/lpr mouse model of lymph node metastasis to show that intranodal pressure increases in both the subiliac lymph node and pro...
Lymph node size is an important variable in ultrasound diagnosis of lymph node metastasis. However, the size criterion often leads to oversight of tumor-positive lymph nodes within the range of "normal" size, such that more accurate diagnostic criteria for lymph node metastasis are required. In this study, we show how diagnosis of lymph node metastasis can be improved by evaluating changes in b...
Although the roles of Delphian lymph node (DLN) metastasis in papillary thyroid cancer (PTC) have been previously reported, there are still limited data on correlations of clinicopathologic factors with DLN metastasis and unique patterns of cervical node subsite metastasis in PTC patients with DLN metastasis. We retrospectively reviewed medical records of 320 patients with a diagnosis of PTC wh...
Distant metastasis from papillary thyroid carcinoma (PTC), particularly from papillary thyroid microcarcinoma, is rare. We present a case of perigastric lymph node metastasis from PTC in a patient with early gastric cancer and breast cancer. During post-surgical follow-up for breast cancer, a 56-year-old woman was diagnosed incidentally with early gastric cancer and synchronous left thyroid can...
AIM To explore the features and prognostic value of lymph node metastasis in patients with T1-stage colorectal cancer (CRC). METHODS In all, 321 cases of T1-stage CRC were selected from 10132 patients with CRC who received surgical therapy in six large-scale hospitals in China and were retrospectively analyzed. Univariate and multivariate analyses were performed to analyze the risk factors fo...
