BACKGROUND Gastric carcinoma and primary gastric lymphoma (PGL) are the two most common malignancies in stomach. The purpose of this study was to screen and validate a biomarker of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) for distinguishing advanced gastric carcinoma (AGC) from PGL for clinical applications. METHODOLOGY/PRINCIPAL FINDINGS We...

BACKGROUND Gastric cancer is one of the most common malignancies in the world and is the second most common cause of cancer-related death in Korea. Colorectal metastases from gastric adenocarcinoma are known to be very rare. We report an unusual case of rectal metastasis of gastric adenocarcinoma. CASE PRESENTATION We report a case of a 43-year-old female patient with gastric cancer who first...

Mucinous gastric carcinoma (MGC) is a rare histological subtype of gastric cancer. The clinicopathological characteristics and CT features of MGC remain controversial. This study aimed to determine the clinicopathological characteristics and CT features of MGC. We reviewed 62 patients with MGC and 104 patients with non-mucinous gastric carcinoma (NMGC), pathologically confirmed between 2003 and...

OBJECTIVE To investigate the relationship between the perfusion CT features and the clinicopathologically determined prognostic factors in advanced gastric cancer cases. MATERIALS AND METHODS A perfusion CT was performed on 31 patients with gastric cancer one week before surgery using a 16-channel multi-detector CT (MDCT) instrument. The data were analyzed with commercially available software...

Intra-abdominal fibromatosis (IAF) may arise either sporadically or in association with familial adenomatous polyposis. The characteristics of fibromatosis are slow-growth, benign histological features, and aggressive local invasion. Surgery remains a reasonable first treatment option. Here, we report 2 cases of a phenomenon rarely described in published literature, IAF after gastrectomy for ga...

BACKGROUND Image texture analysis is a noninvasive technique for quantifying intratumoral heterogeneity, with derived texture features reported to be closely related to the treatment outcome of tumors. Gastric cancer is one of the most common tumors and the third leading cause of cancer-related deaths worldwide. Although trastuzumab is associated with a survival gain among patients with human e...

OBJECTIVE To retrospectively analyze the qualitative CT features that correlate with human epidermal growth factor receptor 2 (HER2)-expression in pathologically-proven gastric cancers. MATERIALS AND METHODS A total of 181 patients with pathologically-proven unresectable gastric cancers with HER2-expression (HER2-positive [n = 32] and negative [n = 149]) were included. CT features of primary ...

INTRODUCTION Gastric cancer is the fourth most common cancer and the second leading cause of death from cancer. Only complete resection of all gross disease with negative microscopic margins (R0 resection) provides a long-term survival benefit, and the overall 5-year relative survival rate is approximately 20%. To improve survival and quality of life, new therapeutic approaches have been introd...

This is a case report of a gastro-lymphatic fistula which appeared during chemoradiotherapy for advanced esophageal cancer. A 60-year-old male was referred to the University of the Ryukyus Hospital because of a 10 kg monthly weight loss and dysphagia. Computed tomography (CT) scans indicated thickened esophageal wall at the lower thoracic esophagus and a swollen lymph node attached to the lesse...

AIM To determine the relationship between F-18 fluorodeoxyglucose (FDG) uptake of bone marrow (BM) on positron emission tomography/computed tomography (PET/CT) and clinical factors and to assess the prognostic value of FDG uptake of BM in gastric carcinoma. METHODS We retrospectively enrolled 309 gastric cancer patients who underwent staging FDG PET/CT and curative surgical resection. FDG upt...
