Abstract
Background and study aims Gastric cancer (GC) is one of the leading causes of malignancy-related death in Vietnam, with increasing incidence of non-cardia early gastric cancer (N-EGC). Data on accurate diagnosis of EGC and treatment by endoscopic submucosal dissection (ESD) in Vietnam are very sparse. The aim of this study was to describe the characteristics of N-EGC and evaluate the effectiveness and the safety of ESD in Central Vietnam. Patients and methods We prospectively enrolled patients with N-EGC detected by magnified chromoendoscopy from December 2013 to August, 2018 in Central Vietnam. Selected cases of N-EGC received standardized ESD technique and have been following up carefully as in protocol. Results Among 606 GC patients, 46 had N-GEC and underwent ESD. The depth of invasion was pT1a in 33 (71.7 %), pT1b1 in 10 (21.7 %), and pT1b2 in three cases (6.6 %). Mild chronic atrophic gastritis, most being C2 (63 %), and gastritis-like EGC that did not appear malignant was the predominant type. ESD achieved a 97.8 % en bloc resection rate; the mean procedure time was 76 ± 22 minutes (range 24-155), and mean endoscopic tumor size was 23 ± 5 mm (range 13-52) and ESD sample size was 28 ± 7 mm (range 16.5-60). Complications consisted of two patients with bleeding and one with a minor perforation, all of which were successfully managed by endoscopy. The longest and the mean follow-up times were 84 and 64 months, respectively, with no recurrence. Conclusions A significant proportion patients with N-EGC have a background mucosa of mild chronic atrophic gastritis. Our results 7 years after starting ESD demonstrate early promising outcomes with the procedure.

Abstract
We encountered a rare case that involved the superficial spreading type of early gastric cancer coexisting with multiple hyperplastic polyps. An 81-year-old Japanese woman with a history of Helicobacter pylori infection was diagnosed with gastric cancer (cT1bN0M0), which presented as a wide, nodular, aggregated protrusion that was associated with multiple pedunculated and sessile polyps. Distal gastrectomy was performed, and the resected specimen involved an 8 cm × 4 cm nodular aggregated protruding lesion and 15 polyps that were 2-20 mm in size. Histopathological examination revealed that the nodular aggregated protruding lesion was a mucosal adenocarcinoma and that the multiple polyps were hyperplastic. The coexistence of multiple hyperplastic polyps and mucosal adenocarcinoma with nodular aggregated protrusions suggested that the mucosal adenocarcinoma had developed from a fusion of multifocal hyperplastic lesions. This may have occurred via a hyperplasia-carcinoma sequence related to the Helicobacter pylori infection. The superficial spreading type of early gastric cancer has a potential developed from a fusion of multifocal hyperplastic polyps.

Abstract
Situs inversus totalis (SIT) is a congenital anomaly characterized by a complete mirror-image transposition of the thoracic and abdominal viscera. We report on a rare case of superficial spreading gastric cancer associated with SIT in a 66-year-old woman referred to our hospital for examination of gastric cancer initially diagnosed by medical check-up. Esophagogastroduodenoscopy showed a slightly depressed lesion in the lesser curvature side of the stomach. Abdominal contrast-enhanced computed tomography showed complete transposition of the abdominal viscera, confirming SIT. The patient underwent total gastrectomy with regional lymph node dissection and Roux-en-Y reconstruction. Gross examination of the surgically resected specimen showed a slightly depressed lesion measuring 12×8 cm in diameter, and histopathology confirmed the diagnosis of signet-ring cell carcinoma, confined to the gastric mucosal layer without lymph node metastasis. The postoperative course was favorable, and the patient has been well without evidence of recurrence for 11 years following the operation. To the best of our knowledge, this is only the second case of a superficial spreading-type gastric cancer in a patient with SIT reported in the English literature.

Abstract
Superficial spreading early gastric cancer (EGC) is a rare disease that is treated mainly by surgery. There are few studies on the safety of endoscopic treatment for patients with superficial spreading EGC. The aims of this study were to (1) investigate the risk of lymph node metastasis of superficial spreading EGC and (2) investigate the potential criteria for endoscopic treatment of superficial spreading EGC using surgical specimens.Between 2000 and 2010, patients who received curative surgery of R0 resection at Severance Hospital (Seoul, Korea) for early gastric cancer were enrolled. The superficial spreading EGC was defined as cancer in which the longest tumor length was ≥6 cm. The medical records of the patients were reviewed retrospectively.Of the 3813 patients with EGC, 140 (3.7%) had lesions ≥ 6 cm, whereas 3673 (96.3%) had lesions < 6 cm. Patients with superficial spreading EGC had higher rates of submucosal cancer (59.3% vs 45.7%, P = 0.002), lymphovascular invasion (18.6% vs 9.8%, P < 0.001), and lymph node metastasis (15.7% vs 10.1%, P = 0.033) compared with patients with common EGC (< 6 cm). Multivariate analysis revealed that a tumor ≥ 6 cm was not strongly associated with lymph node metastasis in EGC, as compared with a tumor < 6 cm, but submucosal invasion and lymphovascular invasion were strongly associated with lymph node metastasis in EGC. In mucosal cancer without ulcers, tumors ≥ 6 cm had a higher rate of lymph node metastasis than tumors ≤ 2 cm; however, this trend was not significant (7.7% vs 5.3%, P = 0.455).Superficial spreading EGC was not associated with an increased risk of lymph node metastasis compared with common EGC. We suggest that differentiated intramucosal superficial spreading EGC without ulceration can be treated by endoscopic submucosal dissection.

Abstract
OBJECTIVE The superficial spreading type of early gastric cancer (EGC) possesses unique features different from other types of EGC. We aimed to elucidate the clinicopathological features of superficial spreading type of EGC. MATERIAL AND METHODS We analyzed 1455 EGC lesions from 1398 patients who had undergone surgical treatment at Samsung Medical Center from 2000 to 2002. Then the clinicopathological features of 224 superficial-spreading EGC lesions (15.4%) was compared to that of 1231 lesions of a common type of EGC. RESULTS In the superficial spreading type of EGC, the incidence of undifferentiated type and submucosal invasion were higher than those of common type of EGC (55.4 vs 38.0%, p < .01 and 58.5 vs 37.8%, p < .01, respectively). Lymph node metastasis and lymphovascular invasion were more frequent in superficial spreading type than in common type of EGC (19.2 vs 7.6%, p < .01 and 15.2 vs 7.4%, p < .01, respectively). There was no difference in recurrence rate or 5-year survival rate between the two groups. CONCLUSION Considering higher risk of submucosal invasion and lymph node metastasis in superficial spreading type, a careful consideration should be done before the application of endoscopic resection to the superficial spreading type of EGC.

Abstract
INTRODUCTION We investigated differences in characteristics between the superficial spreading type early gastric cancer (EGC) characterized by a wide and superficial extension and the common type EGC. PATIENTS AND METHODS Between 1982 and 2008, we retrospectively reviewed clinical reports of patients with the EGC treated at Kochi Medical School. RESULTS Sixty-one patients (9.6%) out of 646 patients had the superficial spreading type EGC. The occurrences of diffuse type histology and lymph node metastasis were significantly greater in the superficial spreading type than in the common type. The incidence of EGC confined to the mucosa was significantly greater in the lymph node-positive superficial spreading type than in the lymph node-positive common type. CONCLUSIONS In patients with the superficial spreading type EGC, lymph node metastasis was more prominent regardless of the degree of tumor invasion. Therefore, appropriate extensive lymph node dissection and wide surgical resection are required for the curative resection of the superficial spreading type EGC.

Abstract
The incidence of early gastric cancer (EGC) with duodenal invasion is extremely low, although advanced gastric cancer that arises in the antrum occasionally invades the duodenum. We investigated the clinicopathological features of EGC with duodenal invasion and provided strategies for clinical management. A Medline search was performed using the keyword “early gastric cancer” and “duodenal invasion”. Additional articles were obtained from references within the papers identified by the Medline search. We revealed that EGC with duodenal invasion was of the superficial spreading type of tumor. Tumors > 60 mm in size invaded the duodenum more extensively, and the distance of duodenal invasion from the pyloric ring was further in the elevated type than in the depressed type of tumor. There was no significant difference between the length of duodenal invasion and the histological type of the tumor. Gastric cancer located adjacent to the pyloric ring, even if cancer invasion was confined to the mucosa or submucosa, was more likely to invade the duodenum. The present study reveals that the elevated type of EGC is associated with more extensive duodenal invasion when the tumor size is > 60 mm, thus highlighting the importance of identification of duodenal invasion in these cases. We also reveal that sufficient duodenal resection with a cancer-free distal surgical margin should be performed in cases of duodenal invasion.

Abstract
PURPOSE The present study investigated the prognostic significance of tumor size in gastric carcinoma patients. METHODS Nine hundred seventy-three gastric carcinoma patients who underwent curative gastrectomy were included and hospital records were reviewed to determine the relationship between tumor size and survival. RESULTS First, the patients were divided based on the mean value of the tumor size in respective stages to control selection bias. Only in stages I and III was tumor size a significant independent prognostic factor. Second, we analyzed the appropriate cutoff value for the large tumor. The minimum criterion for a large tumor, which was determined by the receiver-operating characteristic curve for cancer-related death, was 3.5 cm. There were significant differences between patients with large and small tumors with respect to depth of invasion, number of lymph node metastasis, and stage of disease. CONCLUSIONS Tumor size serves as an indicator of prognosis in gastric cancer patients and a tumor size of 3.5 cm can be used as a significant lower limit of standard size criterion.

Abstract
Although the concept of early gastric cancer (EGC) has been accepted, lymph node metastasis is the most important prognostic factor for EGC. Submucosal gastric cancer is greatly concerned because of its high lymph node metastasis incidence accounting for about 20% of all lymph node metastases. Many researchers suggest that reduction surgery should be performed for submucosal gastric cancer patients at a lower risk of developing lymph node metastasis. Submucosal gastric cancer can be divided into 3 levels (Sm1, Sm2, Sm3) based on its depth of invasion, which has been proven useful for predicting lymph node metastasis, directing treatment and evaluating prognosis. Recently, with the advances in clinical pathology and molecular biology, the risk factor for lymph node metastasis of submucosal gastric cancer can be accurately evaluated and its treatment has become rather rational. This paper reviews the relative factors for lymph node metastasis of submucosal gastric cancer and advances in its rational surgical treatment.

Abstract
OBJECTIVES Superficially spreading early gastric cancer is characterized by wide horizontal extension without deep vertical invasion. This study aimed to clarify the clinicopathological characteristics and prognosis of this rare disease. METHODS We defined superficially spreading early gastric cancer as any tumor invading the submucosal layer that measured > or =60 mm in diameter. The clinicopathological characteristics and results of surgery were compared between 60 patients with superficially spreading tumors and 621 patients with the common type (<60 mm in diameter). RESULTS For superficially spreading cancers,significantly higher numbers of female patients, undifferentiated and scirrhous types, infiltrating growth and lymph node metastases were seen. The number of metastatic lymph nodes was greater than in the common type. There was no significant difference in the distribution of metastatic lymph nodes between the two groups. For superficially spreading tumors, wide gastrectomy with extended lymph node dissection was frequently employed. Lymph node metastasis, but not tumor diameter, was a prognostic factor in uni- and multivariate analyses. CONCLUSIONS Although superficially spreading early gastric cancer has histologically distinct properties, gastrectomy with lymph node dissection with sufficient surgical margin could be a suitable treatment.
