BACKGROUND Recent studies show that peroxiredoxin 1 (Prdx1) contributes to the progression and poor prognosis of carcinoma through multiple mechanisms. However, there is little information on its expression and prognostic value in gastric cancer. This study investigated the expression of Prdx1 in gastric cancer, along with evaluating its clinical-pathological and prognostic importance. MATERIAL AND METHODS A total of 189 pairs of gastric cancer and paracarcinomatous tissues were assessed for Prdx1 expression and its association with clinical characteristics...

BACKGROUND: Despite all advances regarding the surgical treatment of gastric cancer (GC), duodenal stump fistula (DF) continues to negatively affect postoperative outcomes. This study aimed to assess DF regarding its incidence, risk factors, management and impact on overall survival. METHODS: We retrospectively analyzed 562 consecutive patients who underwent gastrectomy for GC between 2009 and 2017. Clinicopathological characteristics analysis was performed comparing DF, other surgical fistulas and patients with uneventful postoperative course...

Accumulating evidence suggests that the aberrant expression of long non-coding RNAs is closely related to the carcinogenesis and progression of gastric cancer (GC), which is a type of prevalent tumor with a high incidence and mortality rate. However, it is still a challenge to find reliable biomarkers and to understand their molecular mechanisms in GC. In this study, we first confirmed that LINC00941was up-regulated in GC tumor tissues compared with adjacent normal tissues by RT-PCR, and found that the expression level of LINC00941 was correlated with invasion depth, lymphatic metastasis, and the TNM stage of patients with GC...

The Epstein–Barr virus (EBV) can cause a wide variety of cancers upon infection of different cell types and induces a highly variable composition of the tumor microenvironment (TME). This TME consists of both innate and adaptive immune cells and is not merely an aspecific reaction to the tumor cells. In fact, latent EBV-infected tumor cells utilize several specific mechanisms to form and shape the TME to their own benefit. These mechanisms have been studied largely in the context of EBV+ Hodgkin lymphoma, undifferentiated nasopharyngeal carcinoma, and EBV+ gastric cancer...

BACKGROUND: Understanding the celiac trunk and hepatic artery anatomy is important not only in preventing iatrogenic injuries but also in planning surgical procedures in children. Therefore, the aim of this study is to analyze the prevalence of celiac trunk (CeT) and common hepatic artery (CHA) variations in the pediatric population. MATERIALS AND METHODS: One hundred and seventy-four children (174) who underwent abdominal multidetector computed tomography (MDCT) angiography, either because of trauma or liver transplantation, were analyzed retrospectively...

Gastric cancer is the third most common cause of death in men and the fifth common cause of death in women worldwide. Currently, available advanced imaging modalities can predict R0 resection in most patients in the perioperative period. The aim of this study is to determine the role of serum CK18, MMP-9, and TIMP1 levels in predicting R0 resection in patients with gastric cancer. Fifty consecutive patients scheduled for curative surgery with gastric adenocancer diagnosis between 2013 and 2015 were included in the study...

A 74-year-old man was referred to our hospital for further investigation of a cystic lesion in the pancreatic body, which had been detected by ultrasonography at a local hospital. He was diagnosed as intraductal papillary mucinous neoplasm(IPMN) and further preoperative examinations were conducted. Upper gastrointestinal endoscopy demonstrated a type 0-II c tumor of the greater curvature in the upper third of the stomach. Endoscopic ultrasonography showed no sign of submucosal invasion. Endoscopic submucosal dissection(ESD)was carried out and pathological examination of a specimen revealed well differentiated adenocarcinoma with submucosal invasion, which fulfilled the indication for additional gastrectomy with lymph node dissection...

A 78-year-old woman was diagnosed with a gastrointestinal stromal tumor(GIST)of the stomach, gradually increasing from 5 years prior. The tumor was suspected to invade the pancreatic body tail and spleen, as observed with computed tomography. Because the patient refused to undergo resection, we administered imatinib mesylate for 6 years. Since early rectal cancer was revealed, the patient was referred for resection and underwent laparoscopic low anterior resection and partial gastrectomy. Histopathologically, the tumor was replaced by tissues with myxomatous changes, and no viable tumor cells were detected...

A57 -year-old man was diagnosed with advanced gastric cancer(adenocarcinoma[tub2/por1])with multiple(S3, S4, S5, S6, S8)liver and para-aortic lymph node metastases. The tumor was classified as cT4a, N3, M1, HEP, cStage IV, and the patient received chemotherapy with S-1 plus CDDP(SP). After 10 courses of SP, a CT scan revealed that the primary tumor and the metastases disappeared.

The patient was a 71-year-old woman being treated for liver cirrhosis. She was admitted to our hospital in April 2015 because of dysphasia. Endoscopic examination revealed a tumor in the mid-thoracic esophagus, which was diagnosed as an endocrine cell carcinoma following pathological examination. Contrast-enhanced computed tomography and positron emission tomography did not show lymph node or distant metastases...

Double cancer of intrahepatic cholangiocarcinoma and gastric cancer is rare. A 62-year-old man underwent gastrectomy for gastric cancer. The pathological findings were tub1>tub2, m, ly0, v0, n0, Stage I A. Two years and a month later, a liver tumor(diameter of 3 cm)and a pelvic mass(diameter of 2.5 cm)were observed. Metastasis from gastric cancer was suspected and chemotherapy(SOX)was administered. However, after 5 courses, CT revealed worseningof the liver tumor (diameter of 12 cm)and pelvic mass(diameter of 3 cm)...

INTRODUCTION: The indication of hepatectomy for liver metastasis from gastric cancer has not been definitely established. PATIENTS AND METHODS: Among 12 cases that were performed hepatectomy for liver metastasis from gastric cancer in our institute from 2008 to 2016, we analysed prognosis and the benefit of surgical resection. RESULTS: The overall 5-year survival rates of all cases were 42.3%, and median survival time was 2 years. The overall survival rates of synchronous metastasis was 59...

A 67-year-old man was referred to our hospital with a diagnosis of type 3 gastric cancer in lower third of the stomach. Computed tomography(CT)scan showed no distant metastasis, but peritoneal dissemination from gastric cancer. A laparoscopic exploration diagnosed pStage IV gastric cancer with peritoneal dissemination. Trastuzumab, capecitabine and cisplatin therapy was administered for initially unresectable gastric cancer. After 6courses of chemotherapy, primary lesion and lymph node metastasis shrank, and the peritoneal dissemination did not worsen by CT scan...

A 56-year-old man was diagnosed with advanced adenocarcinoma of the esophagogastric junction. He received 1 course of neoadjuvant chemotherapy with S-1. After neoadjuvant chemotherapy, the primary tumor showed a remarkable decrease in size. Subtotalesophagectomy, D2 lymph node dissection, and reconstruction with a gastric tube through the posterior mediastinal route were performed. Pathological examination showed that most of the cancer cells had been destroyed, with a part where adenocarcinoma mucosa was seen...

A 49-year-old man was diagnosed with advanced gastric cancer, with a chief complaint of epigastric discomfort. Computed tomography revealed multiple liver metastases. S-1 plus cisplatin therapy was administered as first-line chemotherapy, and after 4courses, the liver metastases markedly reduced. Total gastrectomy with D2 lymphadenectomy and a needle biopsy of segment 2 of the liver were performed. Histopathological examination revealed no viable cancer cells in the resected stomach, lymph nodes, or liver tissue...

Mast cells and macrophages can play a role in tumor angiogenesis by stimulating microvascular density (MVD). The density of mast cells positive to tryptase (MCDPT), tumor-associated macrophages (TAMs), and MVD were evaluated in a series of 86 gastric cancer (GC) tissue samples from patients who had undergone potential curative surgery. MCDPT, TAMs, and MVD were assessed in tumor tissue (TT) and in adjacent normal tissue (ANT) by immunohistochemistry and image analysis. Each of the above parameters was correlated with the others and, in particular for TT, with important clinico-pathological features...
