Abstract
OBJECTIVE To investigate the effect of Src homology 2 domain-containing tyrosine phosphatase-2 (SHP2) in tumor-associated macrophages (TAMs), which is mediated by macrophage colony-stimulating factor (M-CSF) secreted by gastric cancer cells, on the development of gastric cancer and its molecular mechanism. METHODS The progression of gastric cancer was detected by nude mouse tumor-bearing experiments. Colony formation assay and cell counting kit-8 (CCK8) assay were used to detect the proliferation capacity of gastric cancer cells. The migration capacity of gastric cancer cells was examined by wound healing assay. Transwell migration and invasion assays were performed on gastric cancer cells. Detection of relevant protein expression using western blotting. RESULTS Overexpression of SHP2 could promote the progression of gastric cancer in nude mice. The results of colony formation assay and CCK8 assay showed that overexpression of SHP2 could enhance the proliferation of gastric cancer cells. It was found by wound healing assay and Transwell assay that overexpression of SHP2 could facilitate the migration and invasion of gastric cancer cells. The results of Western blotting revealed that overexpression of SHP2 could increase the expressions of p-STAT3, s-PD-1, p-Src, p-Lyn, p-PI3K, p-AKT, Arginase-1, MMP1 and MMP3 but decrease the expressions of TBK1 and SOCS1 in TAMs, and also increase the expressions of CD9, TSG101 and s-PD-1 in exosomes. CONCLUSION M-CSF secreted by gastric cancer cells can promote the proliferation, invasion and migration of gastric cancer cells by increasing the expression of SHP2 in TAMs.

Gastric cancer clinical characteristics and their altered trends in South China: An epidemiological study with 2,800 cases spanning 26 years. Front Oncol 2023; 13:976854. [PMID: 36824130 PMCID: PMC9942704 DOI: 10.3389/fonc.2023.976854] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2022] [Accepted: 01/02/2023] [Indexed: 02/09/2023] Open
Abstract
BACKGROUND Gastric cancer (GC) is a serious threat to human health. The clinical GC characteristics in China may be impacted by changes in people's lifestyles and the promotion of early GC (EGC) screening. The present study aims to evaluate the recent trends of GC characteristics in South China and search for hazardous factors limiting the survival time of GC patients. METHODS Data on GC patients that were hospitalized in the Department of Digestive Center, the First Affiliated Hospital, Sun Yat-sen University, from 1994 to 2019 were collected and divided into two categories according to the time when the EGC screening began in China: the PRE group (previous 13 years, 1994-2006) and the PAS group (past 13 years, 2007-2019). RESULTS We found that, although the 5-year survival rate increased in the PAS group compared with the PRE group (P < 0.0001), patients with age ≥60 years or Borrmann type IV still had a worse prognosis. In the PAS group, the larger percentages of elderly patients and patients with Borrmann type IV in the lymphatic metastases (N1) group (41.0% vs. 51.1%, P = 0.0014) and stage IV subgroup (20.7% vs. 32.2%, P = 0.016), respectively, when compared with the PRE group, may have contributed to the poor outcome of GC. By comparing the odds ratio (OR) of 5-year overall survival (OS) in the two 13-year periods, female sex and T2 turned into risk factors because of a greater proportion of Borrmann type IV or elderly patients in the PAS group (OR = 0.983, 95% CI = 0.723-1.336 vs. OR = 1.277, 95% CI = 1.028-1.586 and OR = 1.545, 95% CI = 0.499-4.775 vs. OR = 2.227, 95% CI = 1.124-4.271, respectively). CONCLUSIONS Despite the GC epidemiology changes, the overall prognosis of GC patients has improved in South China. However, old age and Borrmann type IV are still the major restrictions affecting the survival of GC patients, a situation which calls for additional attention.

Specifics of Young Gastric Cancer Patients: A Population-Based Analysis of 46,110 Patients with Gastric Cancer from the German Clinical Cancer Registry Group. Cancers (Basel) 2022; 14:cancers14235927. [PMID: 36497406 PMCID: PMC9739447 DOI: 10.3390/cancers14235927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2022] [Accepted: 11/28/2022] [Indexed: 12/02/2022] Open
Abstract
Introduction: 2−8% of all gastric cancer occurs at a younger age, also known as early-onset gastric cancer (EOGC). The aim of the present work was to use clinical registry data to classify and characterize the young cohort of patients with gastric cancer more precisely. Methods: German Cancer Registry Group of the Society of German Tumor Centers—Network for Care, Quality and Research in Oncology (ADT)was queried for patients with gastric cancer from 2000−2016. An approach that stratified relative distributions of histological subtypes of gastric adenocarcinoma according to age percentiles was used to define and characterize EOGC. Demographics, tumor characteristics, treatment and survival were analyzed. Results: A total of 46,110 patients were included. Comparison of different groups of age with incidences of histological subtypes showed that incidence of signet ring cell carcinoma (SRCC) increased with decreasing age and exceeded pooled incidences of diffuse and intestinal type tumors in the youngest 20% of patients. We selected this group with median age of 53 as EOGC. The proportion of female patients was lower in EOGC than that of elderly patients (43% versus 45%; p < 0.001). EOGC presented more advanced and undifferentiated tumors with G3/4 stages in 77% versus 62%, T3/4 stages in 51% versus 48%, nodal positive tumors in 57% versus 53% and metastasis in 35% versus 30% (p < 0.001) and received less curative treatment (42% versus 52%; p < 0.001). Survival of EOGC was significantly better (five-years survival: 44% versus 31% (p < 0.0001), with age as independent predictor of better survival (HR 0.61; p < 0.0001). Conclusion: With this population-based registry study we were able to objectively define a cohort of patients referred to as EOGC. Despite more aggressive/advanced tumors and less curative treatment, survival was significantly better compared to elderly patients, and age was identified as an independent predictor for better survival.

Abstract
We aimed to determine the clinical characteristics and prognosis factors of young patients with gastric cancer (GC).A total of 101 young patients with GC referred to Zhengzhou University People's Hospital, Henan province, China between January 1st, 2003 and June 1st, 2015 were retrospectively reviewed. The medical records included ages, genders, marital status, family history of tumors, comorbidity, Helicobacter pylori (H.pylori) infection, fibrinogen, prealbumin, alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), tumor location, tumor size, TNM stage, differentiation of the tumor, WHO type, treatment method and prognostic factors effect were further assessed.The mean age of GC patients in our group was 26.0 years. The incidence was slightly higher in females (female: male = 1.1:1). Some patients had the family history of tumor and H.pylori infection (2.0%, 6.9%). The tumor sizes were mainly under 5 cm (52.4%) and the most locations were in the antrum (43.5%) and body (42.5%). A large number of patients were diagnosed as adenocarcinomas (66.3%) and the main histological of GC was poor differentiated (72.3%). Moreover, a high proportion of patients were diagnosed at the stages III-IV (61.4%), and most patients received surgery combined chemotherapy (63.4%), however, the survival outcome was poor. In univariate Cox analysis, tumor sizes, TNM stage were significantly associated with overall survival (OS) and the multivariate Cox analysis demonstrated that TNM stage was significantly associated with OS.GC in young patients has its unique biological and clinical features. A large majority of young patients were diagnosed at their advanced stages with poor prognostic. TNM stage was an independent prognostic factor for young patients with GC, early GC screening in young people should be actively promoted.

Abstract
Early-onset gastric cancer (EOGC) is a serious social burden. For patients with EOGC, typically considered as those aged <45 years, the underlying cause of the disease remains unclear. In addition, several misunderstandings of EOGC remain in clinical practice. Upon diagnosis, numerous patients with EOGC are already at an advanced stage (stage IV) of the disease and are unable to benefit from treatment. Moreover, several conclusions and data obtained from different EOGC studies appear to be to contradictory. The literature indicates that the incidence of EOGC is gradually rising, and that EOGC differs from traditional and familial gastric cancer in terms of clinicopathological characteristics. Patients with EOGC typically exhibit low survival rates, poor prognosis, rapid disease progression, a low degree of differentiation (signet-ring cell tumors are common) and rapid lymph node and distant metastasis, among other characteristics. The molecular genetic mechanisms of EOGC are also significantly different from those of traditional gastric cancer. An improved definition of EOCG may provide a reference for clinical diagnosis and treatment, and clear guidelines may serve as a basis for more accurate diagnosis and the development of effective treatment strategies.

Abstract
Background Gastric cancer is usually an age-related disease and mostly diagnosed after the sixth decade of life, though it may also be diagnosed earlier. Objective The aim of this study is to explore the clinicopathological characteristics and prognosis of gastric carcinoma in young patients. Methods A total of 1379 patients younger than 75 years histologically diagnosed with primary gastric carcinoma underwent gastrectomy. Patients were categorized into three groups based on their age which included young age group (≤40 years), middle-aged group (age 41-60 years), and elderly group (age 61-75 years). The young age group was further subdivided into two groups: Group A (age ≤35 years) and Group B (age 35-40 years). The analysis of the clinicopathological characteristics and prognosis followed thereafter. Results Females predominate in young group (p < 0.001). A significantly higher undifferentiated histological pattern was found in the young age group from the other two groups (p < 0.001). Tumor location in the lower third of the stomach was significantly higher in the young group than the other groups (p < 0.001). T4 stage was common in young patients similar to the middle and old age group (p = 0.049). Distal gastrectomy was performed more in the young age group rather than the middle and old age groups with the following percentage ratios: young group 74.5% (123/165), middle age group 59.9% (429/716), and old age group 52.2% (260/498) (p < 0.001). The 5-year overall survival rate of the young, middle, and old age groups were 46%, 48%, and 39%, respectively, whereas the 5-year overall survival rates of the subgroups of young patients, Group A and Group B, were 33% and 49%, respectively. Multivariate analysis revealed that independent negative prognostic factors were as follows: tumor location (L), p = 0.016, OR = 0.795, 95%CI = [0.659; 0.959]; larger tumor size, p = 0.026, OR = 1.727, 95%CI = [1.067; 2.797]; resection margin, p < 0.001, OR = 2.167, 95%CI = [1.751; 2.682]; tumor stage (T4), p < 0.001, OR = 2.572, 95%CI = [1.709; 3.870]; and nodal involvement N1, p = 0.005, OR = 1.506, 95%CI = [1.123; 2.020]; N2, p < 0.001, OR = 1.708, 95%CI = [1.289; 2.263]; and N3, p < 0.001, OR = 2.986, 95%CI = [2.314; 3.854]. Conclusion The young age groups of patients were predominantly female and had a higher proportion of poorly differentiated and undifferentiated type of tumor; moreover, patients aged <35 years had a poor prognosis. In addition, gastric cancer can occur in patients less than 30 years old, and symptoms suggestive of gastric cancer should be investigated aggressively; therefore, a close scrutiny and monitoring should be done in younger patients especially those associated with high-risk factors which could indicate the presence of the disease at an early stage.

Abstract
Gastric cancer (GC) is one of the most common malignancies worldwide and it is the fourth leading cause of cancer-related death. GC is a multifactorial disease, where both environmental and genetic factors can have an impact on its occurrence and development. The incidence rate of GC rises progressively with age; the median age at diagnosis is 70 years. However, approximately 10% of gastric carcinomas are detected at the age of 45 or younger. Early-onset gastric cancer is a good model to study genetic alterations related to the carcinogenesis process, as young patients are less exposed to environmental carcinogens. Carcinogenesis is a multistage disease process specified by the progressive development of mutations and epigenetic alterations in the expression of various genes, which are responsible for the occurrence of the disease.

Abstract
BACKGROUND The details of gastric cancer in young patients remain unclear because of the low prevalence of the disease. This study aimed to clarify the clinicopathological features and prognosis of gastric cancer in young patients. METHODS From January 2007 to January 2016, patients in their 20s and 30s who were diagnosed with primary gastric cancer at 4 hospitals were enrolled. Their clinical characteristics and prognosis were evaluated. RESULTS The total number of patients was 72. The median age was 36 years, and the ratio of males to females was 1:1. The dominant histological type was undifferentiated type (66/72, 92%). Helicobacter pylori (H. pylori) was positive in 81% (54/67). Although there were some asymptomatic patients in stages I-III, all stage IV patients had some clinical symptoms at the diagnosis. The percentage of stage IV was significantly higher in patients in their 20s than in those in their 30s (75% vs. 25%, P < 0.001). The Kaplan-Meier method showed that the overall survival of patients in their 20s was significantly lower than that of patients in their 30s (P = 0.037). CONCLUSIONS A high rate of H. pylori infection was revealed in young gastric cancer patients. The patients in their 20s had a worse prognosis than those in their 30s. We should consider examining the H. pylori infection status for young patients as well as older patients to identify high-risk populations.

Abstract
Gastric cancer (GC) is responsible for 9% of cancer deaths worldwide. Over 950,000 new cases are diagnosed each year, and about 90% of them are in advanced stage, requiring chemotherapy. In Europe there has been research based on pre- and postoperative chemotherapy treatment, using 5-fluorouracil, epirubicin, cisplatin, capecitabine, and docetaxel. Chemotherapy significantly impairs the quality of life of patients; however, the final effects are not always satisfactory. There is scientific evidence that gastric mucus tumors and signet ring cell carcinomas have a pattern of specific signatures, that distinguish them from other gastric cancer subtypes, and may be associated with a poor response to systematic treatment. Signet ring cell carcinoma is less chemosensitive than others, and the increase in the percentage of signet ring cells correlates with resistance to chemotherapy. Perioperative chemotherapy in advanced signet ring cell carcinomas is an independent factor of poor prognosis and survival, which is explained by the toxicity of neoadjuvant treatment. Therefore, curative surgical resection enhanced by standardized lymphadenectomy remains the recommended gold standard in GC therapy. According to presented studies, early detection and aggressive treatments for this subtype of GC is a reasonable approach. This review paper is mostly addressed to physicians who are interested in updating to the state of the art concerning different subtypes of gastric carcinoma.

Abstract
Nowadays, gastric cancer is one of the most common neoplasms and the fourth cause of cancer-related death on the world. Regarding the age at the diagnosis it is divided into early-onset gastric carcinoma (45 years or younger) and conventional gastric cancer (older than 45). Gastric carcinomas are rarely observed in young population and rely mostly on genetic factors, therefore provide the unique model to study genetic and environmental alternations. The latest research on early-onset gastric cancer are trying to explain molecular and genetic basis, because young patients are less exposed to environmental factors predisposing to cancer. In the general population, Helicobacter pylori, has been particularly associated with intestinal subtype of gastric cancers. The significant association of Helicobacter pylori infection in young patients with gastric cancers suggests that the bacterium has an etiologic role in both diffuse and intestinal subtypes of early-onset gastric cancers. In this paper we would like to ascertain the possible role of Helicobacter pylori infection in the development of gastric carcinoma in young patients. The review summarizes recent literature on early-onset gastric cancers with special reference to Helicobacter pylori infection.

Abstract
BACKGROUND Young patients with gastric cancer reportedly have a worse prognosis than older patients due to delayed diagnosis and more aggressive tumor behavior. However, it is unclear whether this applies to early gastric cancer (EGC), for which endoscopic resection is indicated. We investigated the association between age and lymph node metastasis (LNM). METHODS We identified 4055 patients diagnosed with EGC of differentiated histology who underwent surgery. The association between age and LNM was examined using logistic regression for each T stage separately with adjustments for multiple covariates. We compared LNM rates for each of the Japanese Endoscopic Resection Guidelines criteria in younger (< 40 years) and older patients (40 years). RESULTS The median number of lymph nodes examined was the same for T1a and T1b stages (n = 34). The median number of lymph nodes examined was not significantly different within T1a stage (P = 0.093), but within T1b stage, the number of lymph nodes examined was significantly different (P = 0.019). The highest number was between 50 and 59 years (median = 37), and the lowest number was in the 20 to 49 years and older than 70 age brackets (median = 34). LNM rate and age were not significantly associated within each stage (P values 0.269, 0.783 for T1a and T1b, respectively). Among patients fulfilling endoscopic resection criteria, the LNM rate in younger patients was lower than in older patients. CONCLUSIONS In differentiated-type EGC, young age at diagnosis was not associated with LNM rate. Therefore, endoscopic resection criteria for early gastric cancer can be applied to younger patients.

Abstract
BACKGROUND AND OBJECTIVES Gastric cancer in young patients is rare. We analyzed the clinicopathological features and prognosis of early-onset gastric carcinoma. METHODS We retrospectively reviewed patients with gastric adenocarcinoma aged ≤45 years and >45 years at our institution over a 17-year period. Clinicopathological features were compared and survival analysis was performed using Kaplan-Meier curves. RESULTS A total of 121 patients with gastric carcinoma aged ≤45 years were identified. The young group (YG) had a higher incidence of stage III/IV disease (86.8% vs. 57.9%, P < 0.001), poorly-differentiated carcinoma (95.9% vs. 74.4%, P < 0.001), and signet-cell type tumor (88.4% vs. 32.2%, P < 0.001) relative to the older group (OG). The majority of tumors were in the middle third of the stomach in both groups (P = 0.108). Three-year survival in the YG was 87.1%, 32.2%, and 6.9% in stage I/II, III, and IV disease, respectively. Surgical intervention in young patients with advanced carcinoma was not associated with improved survival. Although median survival was shorter in the YG compared to the OG (11.7 vs. 41.0 months, P < 0.001), stage-specific survival was similar. CONCLUSION Early-onset gastric cancer demonstrates advanced stage of disease, and a high incidence of poorly-differentiated and signet-cell type carcinoma. Overall survival is poor with no added benefit to surgical intervention in advanced disease.

Abstract
Introduction: Genetic factors play an important role in the development of gastric cancer (GC), a prevalent malignancy in Central Asia. Recent studies have shown that single-nucleotide polymorphisms (SNPs) in several genes are associated with increased GC risk, indicating that genetic variation contributes to gastric carcinogenesis. Located on chromosome 8q24.2, the prostate stem cell antigen (PSCA) gene encodes a 123-amino acid glycoprotein related to the cell-proliferation inhibition and cell-death induction activity. SNPs in PSCA gene have been found to be associated with gastric cancer risk in a genome-wide association study, but results were not conclusive. This study aimed to investigate the association between two polymorphic variants of PSCA gene (rs2294008 and rs9297976) and the susceptibility to gastric cancer in Uzbekistan. Methods: Two hundred sixty eight patients with gastric cancer and a control group of 248 healthy individuals were included in this study. DNA samples isolated from these groups were genotyped using PCR-RFLP method. Comparative analysis of resulting genotypes showed a statistically significant association between CT genotype and gastric cancer (p=0.03, additive model of inheritance, Cochran-Armitage trend test). Results: Comparative analysis of the distribution of genotypes of rs2976392 polymorphism did not show a statistically significant difference; however, analysis of the distribution of the rs2976392 genotypes in a subgroup of young women revealed a statistically significant (p = 0.04, additive model of inheritance, Cochran-Armitage trend test) increase in the incidence of AA (38%) and AG (56%) genotypes in patients with GC, compared to the controls (20% and 40%). Conclusion: Our findings support that PSCA rs2294008 and rs9297976 polymorphism may contribute to the susceptibility to gastric cancer. Genotyping of these polymorphisms can potentially be recommended as one of the criteria for identification of high risk groups for gastric cancer development in Uzbekistan.

Abstract
BACKGROUND The clinicopathological features and prognosis of gastric cancer in young patients are both limited and controversial. Therefore, the aim of this study was to define the clinicopathological features and prognosis of gastric cancer in young patients after curative resection. METHODS From May 2008 to December 2014, 198 young patients (age ≤ 40 years) and 1096 middle-aged patients (55 ≤ age ≤ 64 years) were enrolled in this study. The clinicopathological features and prognosis of gastric cancer in these patients were analyzed. RESULTS Compared with middle-aged patients, the proportion of females, lower third tumors, tumor size less than 5 cm, poorly differentiated tumors and T1 tumors were significantly higher in young patients (all P < 0.05). The proportions of comorbidity, upper third tumors, well and moderately differentiated tumors, T4 tumors, and positive carcinoembryonic antigen (CEA), alpha fetoprotein (AFP) and carbohydrate antigen (CA) 19-9 were significantly lower in young patients (all P < 0.05). The distributions of N status and CA125 were comparable between young and middle-aged patients (all P > 0.05). The five-year overall survival rates were comparable between young patients and middle-aged patients (62.8 vs 54.7 %, P = 0.307). The tumor location, T status, N status and CA125 were independent predictors of prognosis in young patients. The overall survival of patients with tumors located in the upper or middle third was significantly lower than for those located in the lower third (60.8 vs 50.6 % vs 68.4 %, P = 0.016). The overall survival of CA125-positive patients was significantly lower than CA125-negative patients (49.0 vs 64.4 %, P = 0.001). CONCLUSION The clinicopathological features were significantly different between young and middle-aged patients. The prognosis of gastric cancer in young patients was equivalent to that of middle-aged patients. Tumor location, T status, N status and CA125 were independent risk factors for prognosis in young patients.

Abstract
BACKGROUND Early-onset gastric cancer is relatively rare. To evaluate the clinicopathological features and surgical outcome of young patients with gastric cancer, this retrospective comparative study was conducted. METHODS From 2000 to 2010, 4882 patients underwent surgery for gastric adenocarcinoma in our institution. A total of 136 patients under 40 years old were enrolled as the young group, and a total of 1435 patients aged between 60 and 69 were identified as the control group for this study. The patient's characteristics, pathological findings, surgical and clinical outcomes were reviewed, and the risk factors of recurrence were compared between the two groups. RESULTS Among the young group, patients had significantly fewer comorbidities and postoperative complications. The patient proportion having 7 or more lymph node metastases was higher in the young group (25 %) than in the control group (16 %). The presence of lymph node metastasis was identified as a strong risk factor for recurrence (odds ratio = 4.31) in the young group according to the results of the step-wise logistic regression analysis. Although the disease-specific survival at stage II was relatively better in the young group (p = 0.0439) than in the control group, there were no significant differences in overall survival for all stages. CONCLUSION Early-onset gastric cancer is likely to present lymph node metastases. The survival rate of gastric cancer in young patients was equivalent to that in patients in their 60s, which is the typical age at onset.

Abstract
AIM: To analyze the clinicopathological features and prognostic factors of gastric cancer patients with malignant ascites.
METHODS: Clinicopathological data for 223 gastric cancer patients with malignant ascites treated at the Jiangxi Provincial Tumor Hospital between January 2008 and December 2012 were retrospectively analyzed. Survival analysis was conducted using Kaplan-Meier method. Factors influencing survival were analyzed using univariate (Log-rank) and multivariate (Cox) models.
RESULTS: A total of 223 patients (95 females and 128 males, median age, 52 years) were included, accounting for 6.2% of all gastric cancer cases treated at our hospital during the same period. Among them, 50 (22.4%) were young, 38 (17.0%) were senile, 122 (54.7%) underwent curative gastric resection or cytoreductive surgery, 97 (43.5%) presented with malignant ascites at the initial diagnosis of gastric cancer, and 148 (66.4%) received systematic and/or intraperitoneal chemotherapy. Proximal gastric cancer was diagnosed in 22 cases (9.9%) and whole stomach cancer in 12 cases (5.4%). Approximately 79.4% (177/223) of cases were diagnosed with poorly differentiated adenocarcinoma or undifferentiated adenocarcinoma. After a median follow-up period of 9.7 months, it was found that the median survival following diagnosis of malignant ascites was 4.9 months, and the overall one-year survival rate was 12.6%. Univariate analysis revealed that ECOG score, presence of malignant ascites at the initial diagnosis of gastric cancer, history of gastric cancer surgery, total bilirubin level, presence of metastasis in other site(s), and chemotherapy were significant factors affecting the survival (all P < 0.05). Multivariate analysis showed that ECOG score (P = 0.01), presence of malignant ascites at the initial diagnosis of gastric cancer (P = 0.001), presence of metastasis in other site(s) (P = 0.002) and chemotherapy (P < 0.001) were independent prognostic factors.
CONCLUSION: The survival of gastric cancer patients with malignant ascites is relatively short. Worse ECOG score, presence of malignant ascites at the initial diagnosis and presence of metastasis in other site(s) are associated with poor prognosis in gastric cancer patients with malignant ascites, and the survival time could be prolonged by systematic and intraperitoneal chemotherapy.

Abstract
PURPOSE Gastrointestinal cancer (GI) incidence increases with each decade of life and is the leading cause of death in patients aged >70 years. Nevertheless, elderly patients are often excluded or underrepresented in clinical trials. We performed a review of current recommendations in the management of GI elderly cancer patients. METHODS A comprehensive literature review was performed analyzing data about several meta-analysis and studies regarding chemotherapeutic regimens in elderly patients with colorectal and gastroesophageal cancers. RESULTS Most of the studies demonstrated that the elderly experience the same advantages and toxicities from chemotherapy as younger individuals despite the fact that the data reviewed in this article provide evidence that elderly with GI cancers are underrepresented in clinical trials and few trials are conducted addressing the different risks and aims in older population. Each individual should be assessed for an appropriate regimen of treatment in the adjuvant or metastatic gastrointestinal cancer setting, and the decision of how to treat elderly must incorporate goals and preferences of the patient after a careful discussion of risks and benefits. CONCLUSION Chronological age alone is not a sufficient factor to withhold curative/palliative treatment from an elderly GI cancer patient, and cofactors regarding their functional, social, and mental status have to be considered. For this purpose, several tools exist that may be utilized, such as geriatric assessment scores, comorbidity indices, frailty indices, scores for predicting toxicity from chemotherapy, and prognostic indices for survival.

Descriptive epidemiology of gastric adenocarcinoma in the state of Texas by ethnicity: Hispanic versus White non-Hispanic. Gastric Cancer 2012; 15:405-13. [PMID: 22252153 DOI: 10.1007/s10120-011-0127-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2011] [Accepted: 12/03/2011] [Indexed: 02/06/2023]
Abstract
BACKGROUND We aimed to evaluate the clinicopathological and demographic characteristics of gastric adenocarcinoma in Hispanics and compare these trends with those found in non-Hispanic Whites in Texas. METHODS Records of patients with gastric adenocarcinoma found in the Texas Cancer Registry from 1995 to 2006 were reviewed. Four ethnic-geographic groups were formed: Hispanics residing in El Paso County (a county on the Texas-Mexico border), White non-Hispanics in El Paso County, Hispanics from the remaining counties of Texas combined, and White non-Hispanics from the remaining counties of Texas combined. Adjusted prevalence ratios (PRs) for the outcome of late stage at diagnosis were calculated. RESULTS Of 9949 patients, 561 patients were El Paso County residents, of whom 83% were Hispanics. Among the four ethnic-geographic groups, the age-adjusted incidence was the highest in Hispanics in El Paso County (15.5 cases/100000). Tumor pathobiology varied by ethnicity. White non-Hispanics were more likely than Hispanics to have a proximal tumor and less likely to have a poorly differentiated or undifferentiated tumor. In El Paso County, patients in each of the eight age groups under 75 years compared to patients aged ≥85 years were significantly more likely to be at late stage (adjusted PRs 1.44-1.71). CONCLUSION The incidence of gastric adenocarcinoma is higher in Hispanics than in Whites in both El Paso County and the remaining portion of Texas. Hispanics have a higher grade of gastric adenocarcinoma. The prevalence of late stage at the time of diagnosis is higher in younger patients than in older patients.

Abstract
To evaluate the relationship between age and clinicopathological characteristics in gastric carcinoma patients, we performed the meta-analysis based on nine retrospective clinical trials. Comparing elderly patients with young patients it showed lower male/female ratio, more diffuse GC, more Borrmann type IV, more poorly differentiated carcinoma, more peritoneal metastasis, less vascular invasion, fewer partial resections, and better 5-year survival rate. These particular age-related characteristics need to be further investigated.

Abstract
BACKGROUND AND AIM The number of clinical reports of very young (<35 years) patients with gastric cancer are limited. We aimed to investigate the endoscopic and clinicopathological features and long-term prognosis of this unique group of patients. METHODS A prospective endoscopy database review of all consecutive very young patients with gastric cancer was performed. The gender, age, clinical features, endoscopic and pathologic findings, and long-term survival of these very young patients were analyzed and compared with those of elderly patients. RESULTS A total of 210 patients were included with a median age of 31 year, 60.0% was female, and 34.3% presented with alarm features, 19.0% reported family history of gastric cancer. 58.1% of these cancers were located in gastric body, 33.8% were located in the antrum. 63.8% of these cancers were found to be diffuse type; 18.1% of patients underwent curative surgical treatment, and the 5-year survival rate was 42.1%. CONCLUSIONS The study describes that very young patients with gastric cancer were mainly females, who were less likely to present with alarm features, but had a high frequency of family history of gastric cancer; and the majority of these cancers were located in gastric body, and they had similar long-term prognosis compared with elderly counterparts if curative surgical resection was performed.

Abstract
BACKGROUND Gastric cancer (GC) in Israel remains incompletely characterized. The aim of this study was to define the clinical and pathological characteristics of GC in Israel and to compare them to the general Western population. PATIENTS AND METHODS This is a retrospective analysis of 461 consecutive GC patients treated at a single institution between 1995 and 2007. Epidemiological and clinical-pathological data were retrieved from the patients' medical files and the institutional electronic database and analyzed using standard statistical methods. RESULTS Epidemiology, clinical manifestations, histopathological findings, clinical course, and prognostic factors for disease outcome were all similar to those reported in the Western literature. Findings unique to the Israeli population included: (1) rarity of GC-associated risk factors; (2) increased GC incidence in Ashkenazi Jews; (3) high incidence of second primary malignancy and family history of cancer; and (4) no dominancy of proximal GCs. CONCLUSION There do not appear to be any major differences in the biology or clinical manifestations of GC in Israel. Western recommendations for diagnosis and treatment of GC may therefore be applied to the Israeli patient population.

Abstract
AIMS Gastric cancer in the elderly represents a distinct entity with specific clinicopathological characteristics and the majority of affected patients belong to this age group. Subtotal or total gastrectomy with radical lymph node dissection, adjuvant chemoradiotherapy or perioperative chemotherapy represent the only potentially curative treatment options and seem to be performed with acceptable morbidity and mortality rates in selected elderly patients. Published research is very limited due to the strict selection and under-representation of elderly patients in clinical trials. A review of current recommendations and practice was performed. METHODS A comprehensive literature review was performed searching Medline for articles published since 1974, using "gastric cancer", "elderly" and "treatment" as keywords. OBSERVATIONS The data suggest that elderly patients that fulfill the inclusion criteria of clinical trials experience the same advantages and toxicities from chemotherapy as younger patients. Fit elderly patients with operable gastric cancer should be candidates for the standard surgical resection provided that preoperative comorbidities are taken into account. Perioperative chemotherapy or postoperative chemoradiotherapy should be added in case of locally advanced disease. Palliative systemic chemotherapy seems to prolong survival in recurrent and metastatic disease. CONCLUSIONS Chronological age alone is not sufficient reason to withhold curative or palliative treatment from an elderly gastric cancer patient. Performance status does not suffice in order to estimate the general condition of elderly patients and cofactors regarding their functional, social and mental status have to be considered.

Abstract
Background Family history (FH) by different relative types and risk of upper gastrointestinal (UGI) cancers has been only rarely reported; the data on UGI cancer survival are sparse. Methods 600 esophageal squamous cell carcinoma (ESCC) cases, 598 gastric cardia adenocarcinoma cases, and 316 gastric non-cardia adenocarcinoma cases, and 1514 age-, gender-, and neighborhood-matched controls were asked for FH in first degree relatives and non-blood relatives. Odds ratios (ORs) and 95% confidence intervals (CIs) from logistic regressions, and hazard ratios (HRs) from Cox proportional hazard regressions were estimated. Results Increased ESCC risk was associated with FH of any cancer (OR = 1.72, 95% CI = 1.39–2.12), FH of any UGI cancer (OR = 2.28, 95%CI = 1.77–2.95) and FH of esophageal cancer (OR = 2.84, 95%CI = 2.09–3.86), but not FH of non-UGI cancer. Individuals with two or more affected first-degree relatives had 10-fold increased ESCC risk. FH of gastric cardia cancer was associated with an increased risk of all three cancers. Cancer in non-blood relatives was not associated with risk of any UGI cancer. FH of UGI cancer was associated with a poorer survival rate among younger ESCC cases (HR = 1.82, 95%CI = 1.01–3.29). Conclusion These data provide strong evidence that shared susceptibility is involved in esophageal carcinogenesis and also suggest a role in prognosis.

Abstract
BACKGROUND Conflicting results from previous studies on gastric adenocarcinoma (GC) in young patients have led to controversy surrounding the prognosis for young GC patients. METHODS The authors studied 6954 patients with GC who received curative resections. They were classified into three groups: those aged 40 years or less ("young," 12.7%); those aged 41-65 years ("middle-aged," 66.7%); and those aged more than 65 years ("elderly," 20.6%). Clinicopathologic characteristics and overall survival rates were analyzed. RESULTS Young patients were predominately female and had tumors that were histologically undifferentiated. However, in regard to T4 invasion, N3 lymph node metastasis, and TNM stage IV, the characteristics of the tumors of young patients were similar to those of middle-aged and elderly patients. Overall survival rate was significantly better in young patients than middle-aged patients (P = .018) and elderly patients (P < .001). Stratified by TNM stage, young patients showed better overall survival at stage I than middle-aged patients, and at stages I, II, and IIIa than elderly patients. Multivariate analysis indicated that age was an independent prognostic factor (as well as gender, operation type, depth of invasion, and lymph node status). CONCLUSIONS The predominance of female cases and tumors that were histologically undifferentiated were distinctive characteristics in young patients. Young patients could gain a survival benefit after curative resection with stage I disease.

Abstract
BACKGROUND Lymph node (LN) status is a major determinant of prognosis and treatment of gastric adenocarcinoma. The 1997 American Joint Commission on Cancer/Union Internationale Contre le Cancer guidelines were revised, requiring examination of > or =15 LN for staging. METHODS We investigated compliance with these guidelines and the correlation with overall survival (OS) by analyzing 10,807 resected gastric cancers in the Surveillance, Epidemiology and End Results (SEER) database, 1988-2002. Kaplan-Meier survival curves were constructed; survival was compared by using Cox proportional hazards. RESULTS Overall, 29% of cases had > or =15 LN examined. After 1997, the median number of LN assessed increased from 9 to 10 (P < .0001). Factors predictive of adequate LN assessment (ALNA) were higher stage, worse grade, age <74 years, later year of diagnosis, nonwhite race, more extensive surgery, female sex, and SEER region. Differences in the rate of ALNA between regions were noted, ranging from 19.7-53% (P < .0001). Of T1N0 patients, 19% had ALNA. Improved OS was predicted by earlier stage, lower grade, marital status, Asian race, younger age, T-stage, female sex, SEER region, and ALNA. Median OS was highest in the region with the best ALNA rate and worst in the region with the lowest (33 mos vs. 17 mos, P < .0001). Inadequate LN assessment led to poorer survival at every stage (P < .001). CONCLUSION The overwhelming majority of patients have an inadequate LN assessment. ALNA was associated with improved OS, with significant variation across regions. Understaging due to inadequate LN assessment may affect eligibility for adjuvant therapy. Education is required to improve LN retrieval.
