BACKGROUND Transforming growth factor β (TGFβ) receptor signaling is closely associated with the invasion ability of gastric cancer cells. Although Smad signal is a critical integrator of TGFβ receptor signaling transduction systems, not much is known about the role of Smad2 expression in gastric carcinoma. The aim of the current study is to clarify the(More)
OBJECTIVE We report a case of left adrenal schwannoma in a 62-year-old man, incidentally discovered on an abdominal computed tomography. It was successfully treated with laparoscopic adrenalectomy. METHODS On admission, no remarkable findings were recognized in the patient's blood and urine examination, including adrenal function. Laparoscopic left(More)
The purpose of this study was to investigate the impact of the Controlling Nutritional Status (CONUT) score on survival compared with the platelet to lymphocyte ratio (PLR), the neutrophil to lymphocyte ratio (NLR), and the Glasgow Prognostic Score (GPS) in patients with resectable thoracic esophageal squamous cell carcinoma (ESCC). One hundred eighty-five(More)
Tumor lymphangiogenesis is a major prognostic indicator of gastric cancer. Tumor-induced inflammation has been shown to attract tumor-associated macrophages that affect lymphangiogenesis. However, detailed mechanisms of macrophage-induced lymphangiogenesis have not been elucidated. Here, we evaluated the interaction between tumor-associated macrophages and(More)
BACKGROUND Recently, the preoperative immune-nutritional status has been reported to correlate with the survival rate in patients with colorectal cancer (CRC). However, there have been no reports on the relationship between the controlling nutritional status (CONUT) score and the clinical outcome after curative surgery for CRC. We herein evaluated the(More)
BACKGROUND Tumour cells and stromal cells interact in the tumour microenvironment; moreover, stromal cells can acquire abnormalities that contribute to tumour progression. However, interactions between lymphatic endothelial cells (LECs) and tumour cells are largely unexamined. In this study, we aimed to determine whether tumour-specific LECs inhabit the(More)
We report a case of long-term survival with complete remission after hepatic arterial infusion chemotherapy (HAIC) for liver metastasis from gastric cancer. A 62-year-old man underwent radical distal gastrectomy with D2 lymphadenectomy for an advanced gastric cancer. Solitary liver metastasis in the S2/3 segment was detected 26 months after initial surgery.(More)
BACKGROUND Chylous leakage is a well-known complication after esophagectomy, but cervical chylous leakage is relatively rare, and considerable controversy remains regarding the appropriate management strategies. We herein report a case of cervical chylous leakage treated successfully by lipiodol lymphangiography. CASE PRESENTATION The patient, a(More)
BACKGROUND The aim of this study was to clarify the operative mortality and long-term survival of gastrectomy for elderly patients with gastric cancer. METHODS A total of 461 patients who underwent gastrectomy for gastric cancer in our hospital were classified as elderly group (≥80 years-old, 95 patients) and control group (60-69 years-old, 366 patients).(More)
Brain metastasis from gastric cancer is fairly uncommon and prognosis is dismal. We report a case of early gastric cancer with brain metastasis arising 8 years after gastrectomy. A 78-year-old Japanese female presented to our hospital complaining of dizziness, 8 years after undergoing gastrectomy for gastric cancer. Histopathological type of the tumor was(More)
