Gastric cancer can be classified into three subgroups according to pattern of tumor infiltration into the surrounding tissue: INFa (expanding growth and a distinct border with the surrounding tissue), INFc (infiltrating growth and an indistinct border with the surrounding tissue), and INFb (in-between a and c). How the tumor infiltration pattern (INF)(More)
The causes of melena or hematochezia in 48 pediatric patients were examined. Malrotation with volvulus was an important cause of hemorrhage during the newborn period, and intussusception was very typical in patients aged from 1 month to 1 year. Polyps of the rectum and colon were the most common causes of melena or hematochezia in patients older than 1(More)
A 48-year-old male was admitted to our hospital in 1988 with injury by a traffic accident, resulting in fracture of the right rib, right clavicle, and pelvic. The patient came to us again with a chief complaint of abdominal pain in May, 1991 when digestive tract gas was observed in the right pleural cavity casting a doubt of diaphragmatic hernia. Chest CT(More)
Adjuvant chemotherapy is an indispensable component of treatment for preventing recurrence in advanced gastric cancer patients after macroscopically complete tumor resection (R0). However, the efficacy of this treatment for patients with T2N0 and T3N0 gastric cancer is not well characterized. This study examined 1019 T1, 126 T2N0, and 67 T3N0 gastric(More)
The peritoneum is the most frequent site of recurrence for gastric cancer after gastrectomy, followed by the liver and lymph nodes. In contrast, metastasis to the thymus is rare. Annual surveillance with computed tomography was performed on a 67-year-old man who previously underwent a distal gastrectomy and D2 lymph node dissection for gastric cancer at(More)
BACKGROUND Thymic stromal lymphopoietin (TSLP) plays an important role in promoting tumor survival, by manipulating the immune response and angiogenesis. However, the clinical significance of TSLP in gastric cancer is unclear. METHODS Immunohistochemistry was used to investigate TSLP expression in non-cancerous gastric mucosa and gastric cancer tissue(More)
The neutrophil–lymphocyte ratio (NLR) is a biochemical marker of the systemic inflammatory response and has been associated with prognosis for various types of cancer. This retrospective study investigates the relationship between the pre- and postoperative NLR and the prognosis of gastric cancer patients. The subjects were 280 patients who underwent(More)
BACKGROUND Reportedly, the recently established postoperative adjuvant chemotherapies (ADJs) with tegafur and uracil (UFT) or fluoropyrimidine S (S-1) show better survival than surgery alone in patients with advanced gastric cancer (GC). We analyzed chronological changes in postoperative prognosis of patients with advanced GC in our institute, and(More)
BACKGROUND Although the clinicopathologic features and prognosis of Borrmann type advanced gastric cancer has been well characterized, those of advanced gastric cancer simulating early gastric cancer (AGC simulating EGC) still remains unclear. METHODS We reviewed 1985 gastric cancer patients who had undergone gastrectomy at our hospital to determine the(More)
Optimal treatment of patients with gastric cancer with synchronous distant metastases is palliative chemotherapy. However, occasionally gastrectomy should be selected due to control bleeding from tumors, perforation, or obstruction. The aim of this study is to evaluate the survival benefits of non-curative gastrectomy for patients with synchronous distant(More)
