Pulmonary tumor thrombotic microangiopathy (PTTM) is an uncommon cancer-related complication that has been most frequently reported to be associated with adenocarcinoma. We present a case of PTTM which developed in a 60-year-old man with esophageal carcinoma. One year after definitive treatment of the tumor, he developed pulmonary hypertension.(More)
AIM We planned a randomized, open-label trial to evaluate differences between pre-emptive and reactive skin treatment for panitumumab (Pmab)-associated skin toxicities in Japanese patients with metastatic colorectal cancer. PATIENTS & METHODS Patients receiving third-line Pmab-containing regimens were randomized to pre-emptive or reactive treatment. The(More)
BACKGROUND The Response Evaluation Criteria in Solid Tumors (RECIST) was revised in 2009, based on a large dataset of 6512 patients from 16 trials. However, no gastric cancer patients were included in those data. The purpose of this study was to clarify the difference between RECIST version 1.0 and version 1.1 in advanced gastric cancer. METHODS From 2004(More)
Legionella pneumophila is the principal etiologic agent of Legionnaires' disease. We found that the growth of L. pneumophila was markedly inhibited by its own cell lysate and the inhibitory effect was abolished by heat-treatment of the lysate. The genomic library of L. pneumophila was constructed in Escherichia coli and screened to determine the gene(More)
Spontaneous regression of hepatocellular carcinoma (HCC) is an extraordinary phenomenon that occurs rarely. While more than 80 cases have been described, most have been established via radiological findings or examination of biopsy tissues rather than via pathological examination of a resected specimen. The present report describes a purported case of(More)
24 Background: The HER2 extracellular domain can be quantitatively measured in terms of the serum HER2 level by using a CLIA. Increased serum HER2 levels have been reported to be found in 20-25% of metastatic breast cancer patients and correlated with HER2 protein overexpression, increased tumor volume, and worse prognosis. However, the prevalence of HER2(More)
OBJECTIVE Increased serum human epidermal growth factor receptor 2 levels have been found in metastatic breast cancer patients and are correlated with human epidermal growth factor receptor 2 overexpression in tumor cells. However, the prevalence of serum human epidermal growth factor receptor 2 in gastric cancer patients has not been elucidated. METHODS(More)
A 62-year-old man with right upper abdominal swelling was admitted to our hospital. Abdominal computed tomography (CT) revealed a hepatic abscess. He was treated with percutaneous abscess drainage along with antibiotic therapy. After the treatment, the patient was discharged. However, we failed to notice a fish bone, which had been revealed in the CT scan.(More)
We previously reported that a 3D coculture system for hematopoietic cells with spatial development of stromal cells in nonwoven fabrics was superior to a conventional 2D coculture system with respect to progenitor expansion and stem cell maintenance. The hematopoietic environments in 2D and 3D coculture systems were compared and it was found there were no(More)
A 51-year-old man was referred to our hospital with adenocarcinoma of sigmoid colon with multiple lymph node metastasis. At the time of admission, he had dyspnea, and computed tomography (CT) showed typical signs of lymphangitis carcinomatosa of the lung. Combination of mFOLFOX6 and bevacizumab was started. After start of the therapy, CT revealed an(More)
