scirrhous gastric carcinoma endoscopy versus upper Gastrointestinal Radiography
Radiology, 2004Co-Authors: Misuk Park, Byung Se Choi, Kyoung Won Kim, Seungjae Myung, Ah Young Kim, Tae Kyoung Kim, Pyo Nyun Kim, Nam Ju Lee, Jeong Kyung Lee, Moon Gyu LeeAbstract:PURPOSE: To compare the accuracy of upper Gastrointestinal (UGI) series and endoscopic examination in the diagnosis and localization of scirrhous gastric carcinoma. MATERIALS AND METHODS: Seventy-two patients with pathologically proved scirrhous gastric carcinoma in surgical specimens were included. Preoperative reports at UGI series and endoscopic examination, which included impressions on the location and extent of the tumor, were compared with pathology reports, and the accuracy of the preoperative reports was calculated. Two Gastrointestinal radiologists retrospectively reviewed the appearance of mucosa at UGI series. RESULTS: Preoperative diagnoses at endoscopy were Borrmann type IV carcinoma in 28 patients (39%), type III carcinoma in 29 (40%), early gastric carcinoma in seven (10%), lymphoma in six (8%), atrophic gastritis in one (3%), and type II carcinoma in one (3%). Preoperative diagnoses at UGI series were type IV carcinoma in 44 patients (61%), type III carcinoma in 25 (35%), lymphoma in two ...

radiographic findings of primary b cell lymphoma of the stomach low grade versus high grade malignancy in relation to the mucosa associated lymphoid tissue concept
American Journal of Roentgenology, 2002Co-Authors: Misuk Park, Jeongsik Yu, Chanil Park, Sangwook YoonAbstract:OBJECTIVE. We undertook this study to assess how well double-contrast Radiography and CT allow radiologists to differentiate low-grade from high-grade mucosa-associated lymphoid tissue (MALT) lymphoma of the stomach.MATERIALS AND METHODS. We retrospectively reviewed the upper Gastrointestinal radiographs and contrast-enhanced CT scans of 57 patients with pathologically proven primary gastric lymphoma (low-grade [n = 29] and high-grade [n = 28] MALT lymphoma).RESULTS. On upper Gastrointestinal Radiography, ulceration (39%) was the most common finding in low-grade lymphoma, whereas polypoid appearance (38%) was the most common in high-grade lymphoma. In the 29 patients (33 lesions) with low-grade MALT lymphoma, upper Gastrointestinal Radiography revealed 13 ulcerative lesions (39%), 10 nodular lesions (30%), four infiltrative lesions (12%), two polypoid lesions (6%), and four combined lesions (12%). In the 28 patients (29 lesions) with high-grade lymphoma, upper Gastrointestinal Radiography revealed 11 poly...

simultaneous early adenocarcinoma and mucosa associated lymphoid tissue malt lymphoma of the stomach associated with helicobacter pylori infection
Gastric Cancer, 2003Co-Authors: Takehiro Sakai, Yuta Ogura, Junichi Narita, Takemichi Suto, Daisuke Kimura, Susumu Ainai, Hajime Fujita, Mitsuru KamadaAbstract:The simultaneous association of gastric carcinoma with gastric lymphoma is a rare event. Recent studies have suggested that not only gastric cancer but also primary gastric lymphomas, especially those of mucosa-associated lymphoid tissue (MALT) type, are associated with Helicobacter pylori infection. We report on a 51-year-old woman who was referred to our hospital for the evaluation of abnormal shadows revealed by an upper Gastrointestinal Radiography series. Endoscopy of the upper Gastrointestinal tract revealed early cancer in the middle body of the stomach. Biopsy of the lesion subsequently proved it to be a signet-ring cell carcinoma. Total gastrectomy was performed, under a diagnosis of early gastric carcinoma. The resected specimen revealed two grossly separate lesions. Histological examination confirmed that the gastric body lesion was compatible with early moderately differentiated tubular adenocarcinoma of type 0-IIc, while the lesion of the fundus corresponded to MALT lymphoma. H. pylori was detected, and chronic gastritis was also present in the resected gastric specimen. H. pylori infection may have played a major role in the development of both the MALT lymphoma and the adenocarcinoma of the stomach in this patient.
