Functional mitral regurgitation (MR) is common in patients with heart failure and left ventricular (LV) dysfunction. MitraClip (MC) is a novel therapeutic option for patients with high-risk MR. Similar to LV dysfunction, right ventricular dysfunction (RVD) is an important predictor of patients with heart failure. We aimed to clarify the effect of RVD on outcomes of functional MR and LV dysfunction after MC implantation. We examined 117 patients with severe functional MR and reduced LV ejection fraction (≤40%) treated with MC...

Patients with lung adenocarcinoma may benefit from recently developed molecular targeted therapies. However, analogous advanced treatments are not available for patients with lung squamous cell carcinoma (lung SCC). The survival rate of patients with the advanced stage of lung SCC remains poor. Exploration of novel lung SCC oncogenic pathways might lead to new treatment protocols for the disease. Based on this concept, we have identified microRNA- (miRNA) mediated oncogenic pathways in lung SCC. It is well known that miR-145-5p (the guide strand) functions as a tumor suppressor in several types of cancer...

BACKGROUND: Several studies have examined the impact of anesthetics on cancer recurrence. Isoflurane but not desflurane has protumoral effects. We hypothesize the use of isoflurane but not desflurane during surgery for primary GBM is an independent predictor of disease progression and mortality. METHODS: 378 adult patients were included in the study. The progression free survival (PFS) and overall survival (OS) rates at 1 and 5years were compared in patients who had either desflurane or isoflurane alone or in combination with propofol infusion...

OBJECTIVE: To apply the principles of the Metro-ticket paradigm to develop a prognostic model for patients undergoing hepatic resection of colorectal liver metastasis (CRLM). BACKGROUND: Whereas the hepatocellular "Metro-ticket" prognostic tool utilizes a continuum of tumor size and number, a similar concept of a CRLM Metro-ticket paradigm has not been investigated. METHODS: Tumor Burden Score (TBS) was defined using distance from the origin on a Cartesian plane incorporating maximum tumor size (x-axis) and number of lesions (y-axis)...

Brain metastases (BM) is one of the most crucial distant metastases in patients with non-small cell lung cancer (NSCLC) harboring epidermal growth factor receptor (EGFR) mutations. There is no consensus about which EGFR tyrosine kinase inhibitor (TKI) is most effective against BM in such patients. Here, we compared prognoses of patients with EGFR-TKI naïve EGFR-positive BM treated with erlotinib or gefitinib after BM diagnosis. Of 269 patients with NSCLC treated with EGFR-TKIs at a single institution, we reviewed medical records of 205 patients with documented EGFR mutations...
