The prognosis for individuals diagnosed with hepatocellular carcinoma (HCC) remains poor because of the high frequency of invasive tumor growth, intrahepatic spread, and extrahepatic metastasis. Here, we investigated the role of the standard isoform of CD44 (CD44s), a major adhesion molecule of the extracellular matrix and a cancer stem cell marker, in the(More)
To clarify the clinical features of cancer in the pancreatic remnant. We retrospectively reviewed the clinical and pathological findings of 10 patients who developed remnant pancreatic cancer in our hospital between 2002 and 2012. The KRAS sequences in both the initial pancreatic tumor and remnant pancreatic cancer were examined in two patients. Eight(More)
Enhancer of zeste homolog 2 (EZH2) is the catalytic subunit of the polycomb repressive complex 2 (PRC2). When present in PRC2, EZH2 catalyzes trimethylation on lysine 27 residue of histone H3, resulting in epigenetic silencing of gene expression and cancer progression. We investigated the expression and function of EZH2 in intrahepatic and extrahepatic(More)
BACKGROUND The long-term prognosis of hepatocellular carcinoma (HCC) patients after hepatic resection (HR) remains poor because of limited liver function and frequent recurrences. We created a prognostic system of HCC based on tumor markers and Child-Pugh classification. PATIENTS AND METHODS This study investigated 427 HCC patients and three tumor markers(More)
Chemotherapy can lead to tumor down-staging in patients with initially unresectable colorectal liver metastases (CRLM); however, more than half of such cases are still considered to be unresectable because of disease progression, including multiple or bilobar CRLM, and an insufficient predicted remnant liver volume. In addition, there is little evidence(More)
PURPOSE In this study we examined whether conventional future remnant liver volume (FR volume) or function (FR function) better predicted the operative outcome after major hepatectomy. METHODS Of 510 patients who underwent hepatectomy for various indications, 133 patients with major hepatectomy were enrolled in this study. FR volume and the corresponding(More)
Clinical determinants of liver regeneration induced by portal vein embolization (PVE) and hepatectomy remain unclear. The aims of this study were to investigate how liver regeneration occurs after PVE followed by hepatectomy and to determine which factors strongly promote liver regeneration. Thirty-six patients who underwent both preoperative PVE and major(More)
During hepatic resection, accurate estimation of remnant liver volume and hepatic function is crucial for avoiding postoperative liver failure. The purpose of this study was to identify preoperative factors related to postoperative liver dysfunction according to the percentage of future liver remnant volume (%FLR). A total of 625 patients who underwent(More)
Major hepatectomy is associated with significant morbidity and mortality rates, particularly in patients aged more than 70 years. This study assessed whether physical indicators, such as sarcopenia and visceral fat amount, could predict morbidity and mortality after major hepatectomy. The study enrolled 144 patients who underwent curative major hepatectomy.(More)
