BACKGROUND Capecitabine plus oxaliplatin (CapeOX) is one of the reference doublet cytotoxic chemotherapy treatments for patients with metastatic colorectal cancer. We aimed to compare the efficacy and safety of CapeOX with that of S-1 plus oxaliplatin (SOX), a promising alternative treatment for patients with metastatic colorectal cancer. METHODS In this(More)
BACKGROUND Synchronous liver metastases are detected in approximately 25% of colorectal cancer patients at diagnosis. The rates of local failure and distant metastasis are substantial in these patients, even after undergoing aggressive treatments including resection of primary and metastatic liver tumors. The purpose of this study was to determine whether(More)
Brain metastases from colorectal carcinoma (CRC) are rare. The objectives of this study are to assess the natural history, outcome, and possible prognostic factors in CRC patients with brain metastases. Between 1995 and 2008, 8,732 patients with CRC were treated at Yonsei University Health System. Brain metastases were found in 1.4% of these patients.(More)
OBJECTIVE E-cadherin (ECD) and urokinase plasminogen activator (uPA) have been noted as markers for tumor metastasis and prognosis in several tumors. We thus investigated the relationship between the expression of ECD and uPA and the clinicopathological characteristics in pancreatic cancer. METHODS The expression of ECD and uPA was evaluated in pancreatic(More)
BACKGROUND Choosing the most effective approach for treating rectal cancer with mesorectal fascia (MRF) involvement or closeness and synchronous distant metastases is a current clinical challenge. The aim of this retrospective study was to determine if upfront systemic chemotherapy and short-course radiotherapy (RT) with delayed surgery enables R0(More)
BACKGROUND Krüppel-like factor 4 (KLF4) is involved in many important cellular processes such as growth, development, differentiation, proliferation, and apoptosis. The purpose of this study was to determine the significance of KLF4 in both tumors and normal tissues of patients with colorectal cancer (CRC). METHODS Between January 2003 and June 2005, 125(More)
PURPOSE The combination of gemcitabine and docetaxel (GD) is used to effectively treat patients with soft tissue sarcoma (STS). It is widely considered that the conventional doses used are too high for long term use and many patients must discontinue GD treatment due to its toxicity. Therefore, to determine the appropriate dose meeting acceptable efficacy(More)
We report updated progression-free survival (PFS) and overall survival (OS) data from a trial that compared capecitabine plus oxaliplatin (CapeOX) versus S-1 plus oxaliplatin (SOX) for the first-line treatment of metastatic colorectal cancer. This trial was a randomized, two-armed, non-inferiority phase 3 comparison of CapeOX (capecitabine 1000 mg/m2 twice(More)
Combined hepatocellular-cholangiocarcinoma (cHCC-CC) is a rare form of primary liver cancer composed of cells with histopathologic features of both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). Because of its low incidence, the information on clinical outcomes of cHCC-CC is very limited and there are no published reports describing(More)
PURPOSE This phase II trial first describes the combination chemotherapy of biweekly irinotecan plus S-1 (biweekly IRIS) for pretreated advanced gastric cancer (AGC) patients. METHODS Patients who had previously been treated with greater than or equal to one regimen were enrolled. They received S-1 35 mg/m(2) twice daily on days 1-14 and irinotecan 150(More)
