Abstract
Gastric cancer (GC) is one of the most common malignant tumors of the digestive tract, posing a significant risk to human health. Over the past 10 years, the pathological characteristics and the prognosis of GC have been determined based on the locations of the tumors that were then classified into two types-proximal and distal GC. This review focuses on the differences in epidemiology, etiology, cell source, pathological characteristics, gene expression, molecular markers, manifestations, treatment, prognosis, and prevention between proximal and distal GC to provide guidance and a basis for clinical diagnosis and treatment.

Clinical outcomes of early gastric cardiac cancer treated with endoscopic submucosal dissection in patients with different indications. BMC Gastroenterol 2021; 21:119. [PMID: 33711944 PMCID: PMC7953789 DOI: 10.1186/s12876-021-01700-0] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Accepted: 03/01/2021] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Endoscopic submucosal dissection (ESD) has been accepted as a standard treatment for early gastric cardiac cancer (EGCC). Here, we investigate the clinical outcomes of the EGCC patients who underwent ESD in different indications. METHODS From January 2011 to October 2019, we enrolled 502 EGCC lesions from 495 patients which were resected by ESD at our center. We retrospectively analyzed the short-term and long-term clinical outcomes among different indication groups. RESULTS The number of the patients in the absolute indication (AI), expanded indication (EI) and beyond the expanded indication (BEI) groups was 265, 137 and 93, respectively. The en bloc resection rate was 100%, 100% and 98.9% (P = 0.185). The complete resection rate was 99.3%, 98.5% and 74.5%, respectively (P < 0.001). During a median follow-up of 48.1 months, the lymph node metastasis rate was 0%, 0% and 2.3% (P < 0.001). The distant metastasis rate was 0.4%, 0% and 2.3% (P = 0.150). The five-year disease-specific survival rate in the BEI group was 96.6% (P = 0.016), compared to 99.6% in the AI group and 100% in the EI group. CONCLUSION The efficacy for ESD patients in EI group was almost equal to the AI group. Patients in the BEI group showed generally favorable clinical outcomes and needed to be carefully checked after ESD. ESD may be an optional treatment for patients unsuitable for gastrectomy.

Abstract
Background: The prognosis of early cardia cancer and non-cardia cancer is still controversial. It is difficult to collect a large number of cases with complete information in clinical practice. Our study was aimed to identify the differences in clinicopathological characteristics and outcomes of early cardia gastric cancer and non-cardia gastric cancer. Methods: All cases analyzed were from Surveillance, Epidemiology, and End Results database. The data of the patients with early gastric cancer from 2004 to 2010 was retrospectively analyzed. Patients were distributed to cardia cancer group and non-cardia cancer group. Univariate and multivariate analyses were performed to examine differences between groups. The competitive risk model was made to compare the association with cardia cancer and non-cardia cancer about the causes of death. Propensity score matching (PSM) was performed to reduce the bias. Results: We found that cardia cancer was more common in male patients and the White than that in non-cardia cancer at early stage, signet ring cell carcinoma was more common in non-cardia cancer, and the differentiation of non-cardia cancer was worse. Univariate analysis showed that age, marital status, race, tumor location, histology, grade, stage, and operation or not can determine the prognosis. And the prognosis of patients with cardia cancer was worse than that of non-cardia cancer, according to lymph node metastasis and the depth of tumor invasion. Multivariate analysis showed cardia cancer was an independent prognostic factor for poor prognosis. After PSM, cardia cancer still exhibited poor prognosis. Conclusions: At early stage, cardia cancer had a poor prognosis compared with non-cardia cancer. The prevention and treatment of early cardia cancer need to be seriously treated.

Abstract
Background Gastric carcinoma (GC) with second primary malignancy (SPM) is the most frequent combination within the multiple primary malignancies (MPM) group. The presentation of a GC associated with a synchronized SPM in the kidney is extremely rare and unusual. This study presents a rare case of synchronous tumors, describes the main associated risk factors, and emphasizes the need to rule out SPM. Main body We present the case of a 63-year-old Hispanic woman with a history of smoking, weight loss, and gastrointestinal (GI) bleeding. GC was diagnosed by endoscopy, and during her workup for metastatic disease, a synchronous SPM was noted in the left kidney. The patient underwent resection of both tumors with a satisfactory postoperative course. A systematic review of the literature was performed using the Medline/PubMed, Science Direct, Scopus, and Google Scholar databases. A search of the literature yielded 13 relevant articles, in which the following main risk factors were reported: the treatment utilized, the grade and clinical stage, histopathological report, and in some cases survival. It is concluded that advanced age (> 60 years) and smoking are the main associated risk factors. Conclusion Gastric carcinoma is the second most frequent neoplasm of the GI tract and the main neoplasm that presents a SPM. MPM screening is recommended in patients with gastric cancer. The clinical discovery of MPM of renal origin is rare and hence the importance of the current report.

Abstract
The classification of gastric cardiac carcinoma (GCC) is controversial. It is currently grouped with esophageal adenocarcinoma (EAC) as an adenocarcinoma of the gastroesophageal junction (GEJ). Recently, diagnostic criteria for adenocarcinoma in the GEJ were established and GCC was separated from EAC. We viewed published evidence to clarify the GCC entity for better patient management. GCC arises in the cardiac mucosa located from 3 cm below and 2 cm above the GEJ line. Compared with EAC, GCC is more like gastric cancer and affects a higher proportion of female patients, younger patients, those with a lower propensity for reflux disease, a wider histopathologic spectrum, and more complex genomic profiles. Although GCC pathogenesis mechanisms remain unknown, the two-etiology proposal is appealing: in high-risk regions, the Correa pathway with Helicobacter pylori infection, chronic inflammation, low acid and intestinal metaplasia, dysplasia and carcinoma may apply, while in low-risk regions the sequence from reflux toxin-induced mucosal injury and high acid, to intestinal metaplasia, dysplasia and carcinoma may occur. In early GCC a minimal risk of nodal metastasis argues for a role of endoscopic therapy, whereas in advanced GCC, gastric cancer staging rules and treatment strategy appear to be more appropriate than the esophageal cancer staging scheme and therapy for better prognosis stratification and treatment. In this brief review we share recent insights into the epidemiology, histopathology and genetics of GCC and hope that this will stimulate further investigations in order to improve the clinical management of patients with GCC.

Abstract
Background Early gastric carcinoma is heterogeneous and can be divided into early gastric cardiac carcinoma (EGCC) and early gastric non-cardiac carcinoma (EGNCC) groups. At present, differences in clinicopathology remains obscure between EGCC and EGNCC fundus–corpus and antrum–angularis–pylorus subgroups, especially between EGCC with and without oesophageal invasion. Methods In this study, we studied 329 consecutive early gastric carcinoma radical gastrectomies with 70 EGCCs and 259 EGNCCs. Results Compared to the EGNCC antrum–angularis–pylorus (n = 181), but not fundus–corpus (n = 78), sub-group, EGCC showed significantly older age, lower prevalence of the grossly depressed pattern, better tumor differentiation, higher percentage of tubular/papillary adenocarcinoma, but lower frequency of mixed poorly cohesive carcinoma with tubular/papillary adenocarcinoma, and absence of lymph node metastasis (LNM) in tumors with invasion up to superficial submucosa (SM1). In contrast, pure poorly cohesive carcinoma was less frequently seen in EGCCs than in EGNCCs, but mixed poorly cohesive carcinoma with tubular/papillary adenocarcinomas was significantly more common in the EGNCC antrum–angularis–pylorus sub-group than in any other group. No significant differences were found between EGCC and EGNCC sub-groups in gender, tumor size, H. pylori infection rate, and lymphovascular/perineural invasion. EGCC with oesophageal invasion (n = 22), compared to EGCC without (n = 48), showed no significant differences in the H. pylori infection rate and oesophageal columnar, intestinal, or pancreatic metaplasia, except for a higher percentage of the former in size > 2 cm and tubular differentiation. Conclusions There exist distinct clinicopathologic differences between EGCC and EGNCC sub-groups; EGCC was indeed of gastric origin. Further investigations with larger samples are needed to validate these findings.

Abstract
Gastric cancer is common in China. At present, early detection with prompt resection of early gastric carcinoma (EGC) is crucial for improving patient's survival. Because of high heterogeneity of EGC in Chinese patients we reviewed recent clinicopathological and molecular evidence and proposed a grouping EGC in three subgroups according to their location for appropriate management. In group 1 (cardia), most patients with EGC in this small location were elderly men. The tumors originated in the cardiac mucosa with a high proportion of cases with slightly elevated gross patterns and intestinal adenocarcinoma histology with moderate to well differentiation. Poorly cohesive carcinoma was infrequent. As the risk for lymph node metastasis in this kind of tumor was significantly lower than that in the distal stomach, endoscopic therapy is preferred. Group 2 (fundus-corpus), many patients with EGC in this large location were young women. The EGCs originated in the oxyntic mucosa with pure and mixed poorly cohesive carcinomas that are more commonly present in this area than in any other. Most tumors were poorly differentiated with a high risk for lymph node metastasis. Thus, endoscopic therapy may be appropriate for intramucosal, but not for submucosal, carcinoma. Group 3 (antrum-pylorus). EGC tumors arose from the antral mucosa, primarily because of Helicobacter pylori infection, following the Correa gastric cancer tumorigenetic pathway. Erosive and ulcerated gross patterns were most frequently observed. While most EGCs in this location were mainly intestinal adenocarcinomas, poorly differentiated EGCs were substantial in number. Because the risk of lymph node metastasis remains to be illustrated, clinical management requires an individualized approach. This preliminary observation requires verification in large nationwide multicenter studies.

Abstract
Background Gastric carcinoma (GC) is the third most frequent malignancy and the second most common cancer-related cause of death cause worldwide. Gastric intraepithelial neoplasia (GIN) is a well-documented precancerous lesion of GC. In this case–control study, we comprehensively explored the clinical and pathological characteristics of GIN, with the aim to identify its potential risk factors. Patients and methods A total of 630 consecutive patients who underwent endoscopic submucosal dissection or mucosal resection for GIN were initially included. The detailed characteristics of all eligible patients and well-matched healthy controls were recorded and analyzed. Both univariate and multivariate logistic regression analyses were performed and presented with odds ratio (OR) and 95% confidential interval (CI), with additional subgroup analyses based on lesion location. Results A total of 485 GIN-eligible patients were selected, among which 156 had proximal GIN. After follow-up, 434 patients with GIN and 310 age- and gender-matched healthy controls were included in the comparative analyses. Family cancer history (FCH); alcohol abuse; tobacco abuse; intake of high sodium, preserved food, spicy food, and less fruit; Helicobacter pylori (Hp) infection; and atrophic gastritis with intestinal metaplasia were more frequent in GIN patients. Thus, FCH (OR =3.485, 95% CI: 2.031–5.981), high sodium intake (OR =2.830, 95% CI: 1.645–4.868), less fruit intake (OR =4.082, 95% CI: 2.515–6.625), Hp infection (OR =2.307, 95% CI: 1.417–3.755), and atrophic gastritis with intestinal metaplasia (OR =15.070, 95% CI: 8.999–25.237) were independent risk factors for GIN. Further subgroup analyses demonstrated that the specific independent risk factor for proximal GIN was age (OR =2.001, 95% CI: 1.003–3.994), whereas that for distal GIN was intake of high sodium (OR =3.467, 95% CI: 1.896–6.338). Conclusion This study reported a comprehensive overview of the clinical and pathological characteristics of GIN. FCH, high sodium intake, less fruit intake, Hp infection, and atrophic gastritis were identified as the independent risk factors for GIN.

Abstract
BACKGROUND The WHO defines early gastric carcinoma (EGC) as invasive carcinoma up to the submucosal layer, regardless of nodal metastasis. The recent study results indicate that EGC varies in location, histology, nodal metastasis, and prognosis. SUMMARY The heterogeneity in EGC may be related to various types of epithelial stem cells. The most important stem cells include Lgr5+ cells at the base of a gastric unit in the antrum-pylorus-cardia, Mist1+ cells at the isthmus/Troy+ cells at the base in the corpus-fundus, and Sox2+ cells at the base in almost all regions. Dysregulation of these cells along with environmental factors transform stem cells in different regions into malignancy in genetically susceptible populations. KEY MESSAGE The 2 most vulnerable regions for EGC have been found along the lesser curvature: the cardia in elderly patients and antrum-angularis in mid-aged and elderly patients. Most hereditary early-onset gastric carcinomas are concentrated in the corpus-fundus of young women. By histology, the most common EGC type is tubular adenocarcinoma in many growth patterns, starting in the neck of a gastric unit. Worse prognosis has been found in early papillary, compared to tubular, adenocarcinoma, related to deeper penetration, more lymphovascular invasion, and more liver and nodal metastases. Contrary to the common belief, intramucosal signet ring cell carcinoma demonstrates low risk of nodal metastasis, comparable to early intestinal-type EGC. PRACTICAL IMPLICATIONS The overall risk for nodal metastasis in EGC is low but significant. It is urgent to organize multicenter studies on risk of nodal metastasis in EGC in order to establish more reliable clinical practice guidelines to treat EGC patients.

Abstract
The American Joint Committee on Cancer (AJCC) staging scheme requires staging proximal gastric carcinoma (PGC) as esophageal adenocarcinoma (EAC), which has been shown to be controversial by recent research results. To update the current research findings on PGC, we systematically reviewed and analyzed the scientific evidence on key arguments related to PGC. The data of high-quality research articles showed that PGC arised in the cardiac mucosa in the proximal stomach within 3 cm below the gastroesophageal junction. Its incidence is rising in East Asian countries, but decreasing in the West, and plateaued at a low level in the United States. PGC is a slowly progressive cancer with unknown independent risk factors and the mechanisms of pathogenesis. This carcinoma exhibits a wide histopathological spectrum and heterogeneous post-resection patient survival characteristics, and cannot be adequately staged for prognotic stratification by the current AJCC staging classification. The results on PGC genomics reveal unique genetic profiles, especially in East Asian populations. In conclusion, mounting evidence defies a simple placement of PGC in a single category of EAC for disease classification; further investigations on the mechanisms of PGC pathogenesis are urgently needed.

Abstract
Little is known about clinicopathological characteristics of gastric carcinoma (GC) in young (≤40 years) Chinese patients. We aimed in this study to analyze those features along with family history and prognostic factors after resection. We retrospectively reviewed all 4671 GC resections (surgical and endoscopic) performed at our center from 2004 to 2014 and identified 152 (3.2%) consecutive young patients. Patient demographics, clinical results, family history, and endoscopic-pathological findings were analyzed along with the older (>41 years) GC controls recruited in the same study period. Clinicopathological factors related to postresection outcomes were assessed statistically. The trend of GC resections in young patients was not changed over the study period. Compared to old GCs, the young GC cohort was predominant in women, positive family history, middle gastric location, the diffuse histology type, shorter duration of symptoms, and advanced stage (pIII+pIV, 53.3%). Radical resection was carried out in 90.1% (n = 137) with a better 5-year survival rate (70.3%) than palliative surgery (0%, n = 15). There was no significant difference in clinicopathological characteristics between familial GC (FGC, n = 38) and sporadic GC (SGC, n = 114) groups. Very young patients (≤ 30 years, n = 38) showed lower Helicobacter pylori (Hp) infection and significantly higher perineural invasion rates, compared to older (31-40 years) patients. Hp infection was more commonly seen in the Lauren's intestinal type and early pT stages (T1+T2). Independent prognostic factors for worse outcomes included higher serum CA 72-4, CA 125 levels, positive resection margin, and stage pIII-pIV tumors. The 5-year survival rate was significantly higher in patients with radical resection than those without. GCs in young Chinese patients were prevalent in women with advanced stages but showed no significant differences in clinicopathology between FGC and SGC groups. High serum CA 72-4 and CA 125 levels may help identify patients with worse outcomes. Radical resection improved postresection survival.
