Our findings indicate that postmenopausal status is a significant factor of high mean CIMT. These findings add to the growing evidence showing that menopause transition is a critical period for subclinical atherosclerosis development.

Distal cholangiocarcinoma (dCCA) is a rare type of CCA in Asia, even in Opisthorchis viverrini-prevalent Northeastern Thailand. The clinical ambiguity and imprecision of diagnosis surrounding this malignancy result in high mortality due often to advanced/metastatic disease on presentation. We aim to identify a prognostic factor that can improve the performance stratification and influence the outcome of dCCA patients after curative resection. A total of 79 patients who underwent curative-intended surgery for dCCA was enrolled. Possible risk factors for survival were analyzed with log-rank test, and independent factors with Cox regression model. dCCA patients were staged and classified according to the 8th edition the American Joint Committee on Cancer (AJCC) Staging Manual. Results were then compared with the revised classification employing the prognostic factor identified from multivariate analysis. Multivariate analysis revealed that growth pattern (p < 0.01) and distant metastasis (p = 0.012) were independent factors. Growth patterns comprise intraductal (ID), periductal infiltrating (PI), mass-forming (MF), and mixed types. When dCCA patients were grouped into those having good and poor outcomes (with and without ID components, respectively). The survival outcomes significantly differed among patients with and without ID components, which was better than with the 8th AJCC staging system in our cohort. Furthermore, Chi-square test showed that patterns without ID components (PI, MF, PI + MF) correlated with lymph node and distant metastasis. Therefore, classification of dCCA patients after curative-intended surgical resection based on growth pattern provides additional beneficial information for the prediction of survival in dCCA patients.

There was no difference in terms of ADC value between benign lymph nodes and those with metastatic cholangiocarcinoma. Isolated measurement of the ADC value does not contribute to a diagnosis of lymph node metastasis.

Cholangiocarcinoma is an aggressive tumor of the hepatic biliary system and it commonly spreads to the regional lymph nodes, liver and lungs. However, bone metastasis from cholangiocarcinoma is rare compared with other tumors. We herein present the case of a 61-year-old Asian woman who presented with pain in the right scapular area. Magnetic resonance imaging revealed bone destruction and an adjacent soft tissue mass at the right scapula. The findings on computed tomography imaging were compatible with cholangiocarcinoma. Bone biopsy was performed and the diagnosis of cholangiocarcinoma with bone metastasis was confirmed. The survival time was 10 months, despite administration of palliative radiotherapy and chemotherapy. Therefore, bone metastasis from cholangiocarcinoma should be considered as a differential diagnosis in patients who present with an osteolytic bone lesion and a liver mass.
