[PMID: 36385957 PMCID: PMC9646304 DOI: 10.1155/2022/1269435] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 10/04/2022] [Accepted: 10/13/2022] [Indexed: 07/25/2023]
Abstract
OBJECTIVE This systematic review and meta-analysis aimed to ascertain whether sex-based differences influence clinicopathological characteristics and survival outcomes of gastric cancer patients. BACKGROUND Gastric cancer in females has received less attention than in males. Clinicopathological features and survival outcomes of females with gastric cancer have been reported in several studies with controversial results. METHODS We systematically reviewed clinical studies from PubMed, Cochrane Library, Embase, and Web of Science published up to June 2022. The effect sizes of the included studies were estimated using odds ratios (ORs). Heterogeneity was investigated using the χ2 and I 2 tests, while sensitivity analyses were performed to identify the source of substantial heterogeneity. All data used in this study were obtained from previously published studies obviating the need for ethical approval and patient consent. RESULTS Seventy-six studies with 775,003 gastric cancer patients were included in the meta-analysis. Gastric cancer patients were less likely to be females (P < 0.00001). Female patients were younger in age (P < 0.00001) and showed a higher percentage of distal (P < 0.00001), non-cardia (P < 0.00001), undifferentiated (P < 0.00001), diffuse (P < 0.00001), and signet-ring cell carcinoma (P < 0.00001). Female patients showed better prognosis in both 3-year (P = 0.0003) and 5-year overall survival (OS) (P < 0.00001), especially White patients. However, females were associated with lower 5-year OS relative to males in the younger patients (P = 0.0001). CONCLUSIONS In conclusion, gender differences were observed in clinicopathological characteristics and survival outcomes of gastric cancer. Different management of therapy will become necessary for different genders.

Second primary cancers and survival in patients with gastric cancer: association with prediagnosis lifestyles. Eur J Cancer Prev 2019; 28:159-166.

Abstract
To quantify the association between prediagnosis lifestyles with the risk of second primary cancers (SPCs) and survival of patients with gastric first primary cancer (FPC). We recruited 574 gastric patients from two major public hospitals in North Portugal (2001-2006). Smoking, alcohol and dietary habits in the year before FPC diagnosis were evaluated. Patients were followed up to 31 December 2011 for an SPC and to 31 May 2017 for vital status. Cox proportional hazards regression was used to estimate adjusted hazard ratios for incidence of an SPC or death. During follow-up, SPCs were diagnosed in five women and 23 men, and 409 patients died, corresponding to an estimated 10-year cumulative incidence of 5.2% for SPC and an estimated 15-year cumulative mortality of 72.1%. A significantly higher hazard ratio (95% confidence interval) for SPCs was observed in patients reporting a higher consumption of red and processed meat versus the lowest third (4.49: 1.31-15.37), and for mortality in those with heavy alcohol intake versus never drinkers (1.73: 1.00-2.99) and excess weight versus normal weight (1.31: 1.04-1.65); no other significant associations were observed according to prediagnosis lifestyle. Prediagnosis lifestyles may affect the occurrence of an SPC and survival among gastric FPC survivors in the long term.

Abstract
INTRODUCTION The incidence of oesophageal and gastric cardia adenocarcinoma has increased rapidly over the previous two decades. There has been a rise in the number of younger patients affected, and the disease may be more aggressive and have a worse prognosis in these individuals. Current UK guidelines for urgent cancer referral focus on patients who are over 55 years. This study prospectively compares the referral times and outcome in a cohort of patients diagnosed with oesophagogastric cancer under the age of 55 years with a matched cohort over 55 of age. PATIENTS AND METHODS Every patient diagnosed with oesophageal, junctional or gastric cancer under the age of 55 years and every subsequent patient over the age of 55 years was accepted into this study. In all, 17 hospitals participated over a 12-month period. The following data were recorded: duration of symptoms, number of fast-track referrals, duration from GP referral to first hospital visit and stage at presentation. A survival analysis between the two groups was conducted at 2 years after the end of recruitment. RESULTS In total, 102 patients under the age of 55 years were diagnosed with oesophagogastric cancer during the study period. There were fewer fast-track referrals from GPs in this group compared to the over 55-year matched cases (29.4% vs 40.2%). Duration of time from GP referral to first hospital visit was significantly longer in the under 55-year group (median 14 days vs 11 days; P = 0.045 Mann-Whitney). Stage at presentation was similar between groups, but a higher proportion of patients under 55 years were offered a curative treatment plan compared to those over 55 years (P < 0.01). Survival analysis conducted at 2 years after the end of recruitment demonstrated a longer median survival in the under 55-year group (348 days vs 248 days; P = 0.03 log rank). CONCLUSIONS Although there was a longer referral time in patients under the age of 55 years, this had no effect on disease stage at presentation. Patients under the age of 55 years diagnosed with oesophageal or gastric cancer appear to have a better prognosis than those aged over 55 years.

Abstract
BACKGROUND/AIMS Gastric and colorectal cancers are the most common gastrointestinal malignancies in Iran. We aim to compare the survival rates and prognostic factors between these two cancers. METHODS We studied 1873 patients with either gastric or colorectal cancer who were registered in one referral cancer registry center in Tehran, Iran. All patients were followed from their time of diagnosis until December 2006 (as failure time). Survival curves were calculated according to the Kaplan-Meier Method and compared by the Log-rank test. Multivariate analysis of prognostic factors was carried out using the Cox proportional hazard model. RESULTS Of 1873 patients, there were 746 with gastric cancer and 1138 with colorectal cancer. According to the Kaplan-Meier method 1, 3, 5, and 7-year survival rates were 71.2, 37.8, 25.3, and 19.5%, respectively, in gastric cancer patients and 91.1, 73.1, 61, and 54.9%, respectively, in patients with colorectal cancer. Also, univariate analysis showed that age at diagnosis, sex, grade of tumor, and distant metastasis were of prognostic significance in both cancers (P < 0.0001). However, in multivariate analysis, only distant metastasis in colorectal cancer and age at diagnosis, grade of tumor, and distant metastasis in colorectal cancer were identified as independent prognostic factors influencing survival. CONCLUSIONS According to our findings, survival is significantly related to histological differentiation of tumor and distant metastasis in colorectal cancer patients and only to distant metastasis in gastric cancer patients.

Abstract
Gastric cancer is one of the most common cancers and one of the most frequent causes of cancer-related deaths. The incidence, diagnostic studies, and therapeutic options have undergone important changes in the last decades, but the prognosis for gastric cancer patients remains poor, especially in more advanced stages. Surgery is the mainstay of treatment of this disease, even if it is associated with a high rate of locoregional and distant recurrence. There is ongoing debate regarding the role of adjuvant treatment In advanced disease, palliation of symptoms, rather than cure, is the primary goal of patient management. Several combination therapies have been developed and have been examined in phase III trials; however, in most cases, they have failed to demonstrate a survival advantage over the reference arm. This review summarizes the most important recommendations for the management of patients with gastric cancer.

Abstract
PURPOSE The surgical caseload or duration of practice of a surgeon may influence the outcomes of gastric cancer surgery. This study aimed to clarify the surgical quality provided by specialized gastric cancer surgeons. MATERIALS AND METHODS The postoperative courses of 1,877 patients who underwent surgery for gastric cancer were retrospectively reviewed. For classification of the surgeon's expertise, the number of yearly resections performed by, and consecutive years of practice of, the surgeons were used. The outcome measures used were the 30-day mortality and long-term survival. RESULTS Surgical mortalities of patients who underwent surgery by a specialized surgeon and those by a general surgeon revealed no statistically significant difference. A significant difference in the five-year survival rates was found with surgeons with at least two consecutive years of practice compared to those with less than two years, when 50 or more cases had been conducted per year (63.9% and 59.7%; p=0.0380). In cases of four-years of consecutive practice, the five-year survival rate was significantly improved, even if only 10 cases were performed annually (64.9% and 58.3%; p=0.0023), although the best survival rate was found with surgeons that had performed 50 or more surgeries per year. CONCLUSION Improved survival rates, with acceptable surgical mortality, can be achieved for gastric cancer when the surgery is performed by a specialized surgeon. A specialized gastric cancer surgeon can be defined as one who has operated on more than 50 new cases per year, with 2 or more consecutive years of surgical practice.

Abstract
The survival of young patients (< or = 50 years of age) with carcinoma of the oesophagus or stomach has been reported to be poorer than that of their older counterparts. The aim of the current study was to review the outcome of such young patients with oesophagogastric cancer and to compare the outcome in patients with carcinoma of the oesophagus/cardia with patients with carcinoma of the more distal stomach. The study population was 50 patients. Tumour location was oesophagus/cardia (n = 33) and gastric body/antrum (n = 17). The most common presenting symptoms were weight loss (66%), epigastric pain (54%), dysphagia (50%), and heartburn (40%). Seventeen patients had experienced foregut symptoms for a period of > or = 6 months. These patients were more likely to have symptoms of gastro-oesophageal reflux disease and to have received acid suppression therapy than patients with shorter symptom durations. Only 20 patients underwent a potentially curative resection, while 10 underwent open and close laparotomy. The overall median survival was 7 months and the 5-year survival was 8%. Multivariate analysis revealed that surgical resection and UICC stage were the only factors that significantly influenced survival. There was no difference in the survival of patients with proximally situated tumours compared to those with distally located tumours. Wide variations in clinical practice were seen between different surgeons. Consequently, a multidisciplinary team designed to manage all patients with oesophagogastric cancer according to nationally agreed protocols has been established in our hospital. Earlier diagnosis of these tumours is to be encouraged, even if this necessitates the more liberal use of endoscopy in the evaluation of young patients with persistent foregut symptoms.

Abstract
BACKGROUND Gastric cancer has a poor prognosis. The aim of this study was to determine the influence of several clinicopathological variables on outcome in a series of 297 Western patients undergoing surgical resection for gastric adenocarcinoma. METHODS The results were analysed retrospectively and prognostic factors were identified in a univariate and Cox proportional hazards regression model. Mean patient age at the time of operation was 61.9 years; 65.7 per cent were men. Mean follow-up was 7.8 (range 1-15) years. Of the 297 patients undergoing surgery, 70 per cent had subtotal gastrectomy, 26.3 per cent underwent total gastrectomy and 3.7 per cent had proximal gastrectomy. RESULTS The overall survival rate was 38.9 per cent at 5 years. In th univariate analysis, survival-related factors were weight loss (P < 0.05), abdominal mass (P < 0.01), dysphagia (P < 0.001), type of gastrectomy (subtotal gastrectomy versus total gastrectomy, P < 0.001), intention of resection (curative versus palliative resection, P < 0.001), tumour site (P < 0.001), histopathological grade (low versus high grade, P < 0.05), tumour diameter less than 3 cm (P < 0.001), degree of gastric wall invasion (P < 0.001), degree of lymph node invasion (P < 0.001) and stage of the neoplasia (P < 0.001). Other variables had no significant influence. In the multivariate analysis, degree of gastric wall invasion, lymph node invasion, tumour size and dysphagia at presentation were the only independent prognostic variables. CONCLUSION From these data it was possible to derive a prognostic index with which patients could be classified as at low, intermediate or high risk.

Abstract
BACKGROUND The clinicopathologic characteristics and prognosis for patients with node-negative gastric cancer have heretofore remained to be determined. METHODS We analyzed data on 730 of our patients with node-negative gastric cancer who underwent curative gastric resection in the Department of Surgery II, Kyushu University Hospital, between 1965 and 1990, with reference to prognostic factors. The presence of lymph node metastasis was determined by means of routine hematoxylin-eosin staining of excised tissues. RESULTS The 5-year survival rate was 91.7% and the 10-year rate was 88.5%; thus the prognosis was good for patients with node-negative gastric cancer. When the prognosis was analyzed by stratification of each clinicopathologic factor, the survival time was shorter for older patients when the size of the tumor was larger, when the tumor involved the entire stomach, and when-tissues revealed infiltrative growth, serosal invasion, and lymphatic invasion. Extensive lymph node dissection was performed for 86.6% of the patients, and for these patients the prognosis was better, with a statistical difference. In a multivariate analysis, tumor size, serosal invasion, and extensive lymph node dissection proved to be independent prognostic factors for patients with node-negative gastric cancer. CONCLUSIONS Prophylactic lymph node dissection for patients with gastric cancer will prolong the survival time.

Abstract
The aim of this study was to assess whether survival of gastric cancer patients differed between males and females. Although it is well known that the incidence of gastric cancer is higher for men than for women, the existence of a sex-specific prognosis has seldom been addressed. Studies based on population registries have not assessed the role of stage and histology. Cases of histologically confirmed gastric carcinoma were obtained from three Spanish hospitals in Soria (n = 405), Barcelona (n = 249) and Mataró (n = 197). Differences in possible confounders were tested between men and women and survival analyses were performed separately by hospital. Cox's proportional hazards models were used to account for age, tumour stage, histology and tumour sub-location. Only in Mataró was a significant difference in the stage distribution observed between women and men, with a lower proportion of local stage tumours among women (P = 0.047). No statistically significant differences of histological type between men and women were observed in any of the centres. After adjusting for tumour stage and age, women were observed to have significantly better survival in Barcelona (female to male hazard ratio (HR) = 0.578, P < 0.001); this effect was marginal in Soria (HR = 0.788, P = 0.092) and non-significant in Matar-o (HR = 0.895, P = 0.54). Age-adjusted hazard ratios were calculated within each tumour stage. For Barcelona, the effect of better prognosis among women was most marked at local stage (HR = 0.320, P = 0.013), and in Soria at the regional stage (HR = 0.426, P = 0.002). Although in Mataró all HRs were below unity, none were statistically significant. Little effect was observed at the disseminated stage. The other covariables exerted no influence. Women appear to have a better prognosis than men, and the difference could be tumour stage dependent. Confirmation of these findings would give a valuable insight into gastric cancer growth and ultimately be of use in planning treatment.

Abstract
The relationship between family history of gastric carcinoma and gastric carcinoma in Japanese under 40 years of age was analyzed. The subjects were 108 gastric carcinoma patients (86% were diffuse type) at 9 hospitals in the Kanto area of Japan. Firstly, incidence of gastric carcinoma among the parents of the subjects were compared with that in the general population. Observed/expected (O/E) ratios (P-value) were 1.8 (0.06) for all subjects, 1.3 (0.62) for male subjects, 2.1 (0.04) for female subjects, 0.5 (0.41) for early carcinoma, 2.6 (P<0.01) for advanced carcinoma, 2.3 (0.22) for intestinal-type carcinoma and 1.7 (0.13) for diffuse-type carcinoma. Association between gastric carcinoma and parents' history of gastric carcinoma was strong among women and regarding advanced carcinoma, and the difference in O/E ratios between early and advanced carcinoma was remarkable. Secondly, factors related to advanced-stage gastric carcinoma were analyzed. Histological type (diffuse and intestinal types) was not related, but family history of gastric carcinoma among parents and grandparents was related to advanced stage, and the relationship was independent of other factors. The odds ratio (95% confidence interval) was 3.3 (1.1-9.9). Family history may be related to stage of gastric carcinoma through its relationship to the manner or speed of the tumor's progression. We hypothesis that some genetic factor exists which is involved both in progression from early to advanced stage and in occurrence of gastric carcinoma.

Abstract
We reviewed data on 467 patients with advanced gastric carcinoma, taking into consideration tumor size, shape and depth of invasion, and growth pattern, either expanding or infiltrative. Three patterns of penetration were identified: i.e., funnel, column, and mountain patterns. The funnel pattern was predominant in tumors extending into the muscularis propria (pm) or subserosa (ss), and were more widely distributed than the column pattern. The majority of the column type tumors were less than 8 cm in pm or ss, and the mountain type was found in only one case in ss, but their size was widely distributed once cancer cells penetrated the serosa. Patients with the funnel type had a better prognosis than the column or the mountain type, and the difference was significant when cancer invasion extended to the serosa.
