BACKGROUND The aim of this study was to investigate the utility of the apparent diffusion coefficient (ADC) value in diffusion-weighted magnetic resonance imaging (DWMRI) for prediction and early detection of treatment response in advanced esophageal squamous cell carcinoma. METHOD DWMRI was performed in 27 patients with primary cT4 esophageal carcinoma(More)
We herein present the case of a 68-year-old male who suffered an episode of hypoglycemic shock 2 years after undergoing total removal of a bifrontal parasagittal malignant meningioma. Imaging studies revealed three giant hypervascular tumors with a cystic portion in the right lobe, but no confirmed preoperative diagnosis could be made. At laparotomy, liver(More)
Reports suggest that hepatic blood flow may have an association with cancer progression. The aim of the present study was to evaluate whether the hepatic blood flow measured by CT perfusion (CTP) may identify patients at high‑risk for postoperative recurrence of esophageal squamous cell carcinoma (ESCC). Prior to surgery, hepatic CTP images were obtained(More)
OBJECTIVES T1 esophageal squamous cell carcinoma (ESCC) has a low, but still present, risk of lymph node (LN) metastasis. Endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) is often applied for T1 ESCC. To achieve successful treatment by EMR/ESD, the risk of LN metastases, LN recurrence, and hematological recurrence need to be(More)
We evaluated the power of DWIBS in patients with postoperative lymph node recurrence of esophageal cancer and compared with FDG-PET findings. Forty-seven suspected lesions by MDCT were enrolled. No significant difference between DWIBS and PET was observed in sensitivity (95% vs 97%), PPV (83% vs 90%) and overall accuracy rate (81% vs 87%). The ADCs (x10(-3)(More)
BACKGROUND The correlation between the number of pathologic metastatic LNs in patients with esophageal squamous cell carcinoma (ESCC) after neoadjuvant chemoradiotherapy (NACRT) and surgical outcome has rarely been reported. We evaluated the correlation between the number of pathologic metastatic lymph nodes (LNs) and the surgical outcome in ESCC after(More)
BACKGROUND/AIMS There are few second-line regimens available for esophageal cancer. The use of fractionated docetaxel and nedaplatin as second-line chemotherapy was examined in this study. METHODOLOGY Eligibility criteria were follows: histologically-proven squamous cell carcinoma, surgically unresectable disease, failure to respond to chemotherapy with(More)
PURPOSE S-1 is widely used for various cancers. It may be useful for esophageal squamous cell carcinoma (ESCC); however, there are insufficient data. The purpose is to provide results of an analysis of S-1 monotherapy for unresectable and recurrent ESCC. PATIENTS AND METHODS Twenty patients with histologically proven ESCC who were previously treated with(More)
Although percutaneous endoscopic gastrostomy (PEG) is the preferred method to provide enteral nutrition for a longer time period, in obstructive esophageal cancer, we cannot safely perform endoscopic access to the stomach even with the ultrathin endoscope. We experienced 1 fatal case due to esophageal perforation caused by balloon dilation, and hence, we(More)
It is known that cisplatin induces the excretion of zinc from the urine and thereby reduces its serum concentration. However, the fluctuation of these trace elements during or after cisplatin-based chemotherapy has not been evaluated. To answer this question, we performed a clinical study in esophageal cancer patients undergoing cisplatin-based(More)
