1Level of circulating PD-L1 expression in patients with advanced gastric cancer and its clinical implications显示文摘Objective:The programmed cell death-1 receptor/programmed cell death-1 ligand(PD-1/PD-L1) pathway plays a crucial role in tumor evasion from host immunity.This study was designed to evaluate the association between circulating PD-L1 expression and prognosis in patients with advanced gastric cancer.Methods:Totally 80 advanced gastric cancer patients and 40 health controls from Beijing Cancer Hospital were enrolled in the present study.Circulating PD-L1 expression was tested by enzymelinked immunosorbent assay(ELISA).The associations between the expression level of PD-L1 and clinicopathological features and prognosis were analyzed statistically.Results:Expression of PD-L1 in advanced gastric cancer patients was significantly up-regulated compared with health people(P=0.006).The expression of PD-L1 was significantly correlated with differentiation and lymph node metastasis(P=0.026 and P=0.041,respectively).Although we didn't find significant difference in all advanced gastric cancer patients with different PD-L1 expression,the adenocarcinoma patients with higher up-regulated PD-L1 expression had much better prognosis than low expression patients(65.6% vs.44.7%,P=0.028).Conclusions:PD-L1 was elevated in advance gastric cancer patients and may play an important role in tumor immune evasion and patients prognosis.Zhixue Zheng Zhaode Bu Xijuan Liu Lianhai Zhang Ziyu Li Aiwen Wu Xiaojiang Wu Xiaojing Cheng Xiaofang Xing Hong Du Xiaohong Wang Ying Hu Jiafu Ji 2014Chinese Journal of Cancer Research2014,26,1:37
2LGR5 is a promising biomarker for patients with stage Ⅰ and Ⅱ gastric cancer显示文摘Objective: To investigate Leucine-rich repeat-containing G protein-coupled receptor 5 (LGR5) expressions in gastric cancer and to evaluate its clinical significance. Methods: LGR5 expression was assessed by immunohistochemistry in 257 gastric cancer patients after surgery. The relationships between LGR5 expression and clinicopathological features and patients prognosis were statistically analyzed. Results: The expression of LGR5 was significantly higher in gastric cancers as a cancer stem cell marker than in adjacent normal tissues (P<0.001), and more frequently in patients with intestinal type, well-moderate differentiation and stage Ⅰ and Ⅱ (P<0.05). Although we found gastric cancer patients with LGR5 positive expression had a poorer prognosis, it didn't meet statistical significance (P>0.05). LGR5 negative expression was significantly related to the favorable overall survival in stage Ⅰ and Ⅱ gastric cancer patients (P<0.05). Furthermore, patients with high LGR5 expression tended to be more likely to get progression and have poorer progress-free survival (P<0.05). Multivariate Cox regression analysis revealed that LGR5 expression was an independent factor of overall survival for the patients with stage Ⅰ and Ⅱ gastric cancer (P<0.05). Conclusions: Our results show that LGR5 may play an important role in tumorigenesis and progression and would be a powerful marker to predict the prognosis of patients with stage Ⅰ and Ⅱ gastric cancer.Zhaode Bu Zhixue Zheng Lianhai Zhang Ziyu Li Yu Sun Bin Dong Aiwen Wu Xiaojiang Wu Xiaohong Wang Xiaojing Cheng Xiaofang Xing Yingai Li Hong Du Jiafu Ji 2013Chinese Journal of Cancer Research2013,25,1:17
3Depth of tumor invasion and tumor-occupied portions of stomach are predictive factors of intra-abdominal metastasis显示文摘Objective:Diagnostic laparoscopy is recommended for the pretherapeutic staging of gastric cancer to detect any unexpected or unconfirmed intra-abdominal metastasis.The aim of this study was to evaluate the role and indications of diagnostic laparoscopy in the detection of intra-abdominal metastasis.Methods:Standard diagnostic laparoscopy with peritoneal cytology examination was performed prospectively on patients who were clinically diagnosed with primary local advanced gastric cancer(c T≥2M0).We calculated the rate of intra-abdominal metastases identified by diagnostic laparoscopy,and examined the relationship between peritoneal dissemination(P)and cytology results(CY).Split-sample method was applied to find clinical risk factors for intra-abdominal metastasis.Multivariate logistic regression analysis and receiver-operator characteristic(ROC)analysis were performed in training set to find out risk factors of intra-abdominal metastasis,and then validate it in testing set.Results:Out of 249 c M0 patients,51(20.5%)patients with intra-abdominal metastasis were identified by diagnostic laparoscopy,including 20(8.0%)P1CY1,17(6.8%)P0CY1 and 14(5.6%)P1CY0 patients.In the training set,multivariate logistic regression analysis and ROC analysis showed that the depth of tumor invasion on computer tomography(CT)scan≥21 mm and tumor-occupied≥2 portions of stomach are predictive factors of metastasis.In the testing set,when diagnostic laparoscopy was performed on patients who had one or two of these risk factors,the sensitivity and positive predictive value for detecting intra-abdominal metastasis were 90.0%and32.1%,respectively.Conclusions:According to our results,depth of tumor invasion and tumor-occupied portions of stomach are predictive factors of intra-abdominal metastasis.Ziyu Li Zhemin Li Shuqin Jia Zhaode Bu Lianhai Zhang Xiaojiang Wu Shuangxi Li Fei Shan Xin Ji Jiafu Ji 2017Chinese Journal of Cancer Research2017,29,2:14
4Construction and external validation of a nomogram that predicts lymph node metastasis in early gastric cancer patients using preoperative parameters显示文摘Objective: To create a nomogram to predict the incidence of lymph node metastasis(LNM) in early gastric cancer(EGC) patients and to externally validate the nomogram.Methods: To construct the nomogram,we retrospectively analyzed a primary cohort of 272 EGC patients.Univariate analysis and a binary logistic regression were performed.A nomogram predicting the incidence of LNM in EGC patients was created.The discrimination ability of the nomogram was measured using the concordance index(c-index),and the nomogram was also calibrated.Then,another prospective cohort of 81 patients was analyzed to validate the nomogram.Results: In the primary cohort,LNM was pathologically confirmed in 37(13.6%) patients.In multivariate analysis,the presence of an ulcer,the maximum lesion diameter observed via gastroscopy,the thickness of the lesion observed via endoscopic ultrasonography,and the presence of enlarged lymph nodes on computed tomography(CT) were independent risk factors for LNM.A nomogram was then created based on the regression model with the c-index of 0.905,and the calibration curve of the nomogram fell approximately on the ideal 45-degree line.The cut-off score of the nomogram was 110,and the sensitivity,specificity,positive predictive and negative predictive values of the nomogram in the primary cohort were 81.1%,86.0%,47.6% and 96.7%,respectively,and in the prospective validation cohort were 75.0%,91.0%,60.0% and 95.5%,respectively.The calibration curve of the external validation cohort was almost on the 45-degree line.Conclusions: We developed an effective nomogram predicting the incidence of LNM for EGC patients.Yinan Zhang Yiqiang Liu Ji Zhang Xiaojiang Wu Xin Ji Tao Fu Ziyu Li Qi Wu Zhaode Bu Jiafu Ji 2018Chinese Journal of Cancer Research2018,30,6:12
5Prognostic role of lymph node metastasis in early gastric cancer显示文摘Objective: To clarify the relationship between clinicopathological features and lymph node metastasis and to propose the potential indications of lymph node metastasis for prognosis in early gastric cancer(EGC) patients. Methods: We retrospectively observed 226 EGC patients with lymph node resection, and analyzed the associations between lymph node metastasis and clinicopathological parameters using the chi-square test in univariate analysis and logistic regression analysis in multivariate analysis. Overall survival analysis was determined using the Kaplan-Meier and log-rank test. We conducted multivariate prognosis analysis using the Cox proportional hazards model.Results: Of all the EGC patients, 7.5%(17/226) were histologically shown to have lymph node metastasis. The differentiation, lymphovascular invasion and depth of invasion were independent risk factors for lymph node metastasis in EGC. The 5- and 10-year survival rates were significantly lower in patients with lymph node metastasis than in those without and the patients also had shorter progress-free survival time. Lymph node metastasis and tumor size were independent prognostic factors for EGC. The status of the lymph nodes was a significant factor in predicting recurrence or metastasis after surgery. Conclusions: The undifferentiated carcinoma and lymphovascular and/or submucosal invasion were associated with a higher incidence of lymph node metastasis in EGC patients, whom need to perform subsequent D2 lymphadenectomy or laparoscopic lymph node dissection and more rigorous follow-up or additional chemotherapy/radiation after D2 gastrectomy for poor prognosis and high recurrence/metastasis rate.Zhixue Zheng Yiqiang Liu Zhaode Bu Lianhai Zhang Ziyu Li Hong Du Jiafu Ji 2014Chinese Journal of Cancer Research2014,26,2:12
6Oxaliplatin plus S-1 or capecitabine as neoadjuvant or adjuvant chemotherapy for locally advanced gastric cancer with D2lymphadenectomy: 5-year follow-up results of a phase II-III randomized trial显示文摘Objective: To compare the effect of neoadjuvant chemotherapy(NACT) with adjuvant chemotherapy(ACT)using oxaliplatin plus S-1(SOX) or capecitabine(CapeOX) on gastric cancer patients with D2 lymphadenectomy.Methods: This was a two-by-two factorial randomized phase II-III trial, and registered on ISRCTN registry(No. ISRCTN12206108). Locally advanced gastric cancer patients were randomized to neoadjuvant SOX,neoadjuvant CapeOX, adjuvant SOX, or adjuvant CapeOX arms. Primary analysis was performed on an intentionto-treat(ITT) basis using overall survival(OS) as primary endpoint.Results: This trial started in September 2011 and closed in December 2012 with 100 patients enrolled.Treatment completion rate was 56%, 52%, 38% and 30% in the four arms, respectively. NACT group had fewer dropouts due to unacceptable toxicity(P=0.042). Surgical complication rate did not differ by the four groups(P=0.986). No survival significant difference was found comparing NACT with ACT(P=0.664; 5-year-OS: 70% vs.74% respectively), nor between the SOX and CapeOX groups(P=0.252; 5-year-OS: 78% vs. 66% respectively).Subgroup analysis showed SOX significantly improved survival in patients with diffuse type(P=0.048).Conclusions: No significant survival difference was found between NACT and ACT. SOX and CapeOX had good safety and efficacy as neoadjuvant regimens. Diffuse type patients may survive longer due to SOX.Kan Xue Xiangji Ying Zhaode Bu Aiwen Wu Zhongwu Li Lei Tang Lianhai Zhang Yan Zhang Ziyu Li Jiafu Ji 2018Chinese Journal of Cancer Research2018,30,5:10
7Surgical treatment of gastric cancer:Current status and future directions显示文摘Surgery is the most important and effective method for the treatment of gastric cancer.Since the first gastrectomy in the early 19th century,surgical treatment of gastric cancer has undergone more than 100 years of development.With the increasing understanding of gastric cancer and the promotion of a series of clinical trials,the concept of gastric cancer surgery has evolved from the initial'bigger is better'to today’s'standardized surgery'and is developing towards individualized surgery focusing on accurate resection and quality of life.This trend has had a tremendous impact on the development of surgical treatments,such as minimally invasive surgeries,functionpreserving surgeries,and the optimal extent of lymph node dissection.Understanding the development and current status of gastric cancer surgery and exploring the remaining academic controversies are goals that every gastric surgeon should constantly pursue.However,how should gastric cancer surgery develop in the future?What opportunities and challenges will we encounter?In this review,we elaborate on the development and current status of gastric cancer surgery based on a series of clinical studies and discuss the controversy in the development of gastric cancer surgery.Jiahui Chen Zhaode Bu Jiafu Ji 2021Chinese Journal of Cancer Research2021,33,2:6

10Anatomical variation of infra-pyloric artery origination: A prospective multicenter observational study (IPA-Origin)显示文摘Objective: Infra-pyloric artery(IPA) is an important anatomical landmark in treatment of gastric cancer and is the key vessel for pylorus-preserving gastrectomy and subgroup of infra-pyloric lymph nodes. However, its anatomical variation is not thoroughly understood. Our study aimed to clarify the origination of the IPA.Methods: We did this prospective, multicenter, open-label, observational study at gastric surgery departments of34 hospitals in China. Gastric cancer patients aged 18 years or older and scheduled to undergo elective total or distal gastrectomy were assigned. During the surgery, IPA dissecting and exposing the origination point with photographs or video clips were required. The primary outcome was the origination of the IPA. Analysis of variance, χ~2 tests and Fisher's tests were used to analyze the differences between groups. The study is registered at Clinicaltrials.gov(No. NCT03071237).Results: Between May 8 and July 31, 2017, 429 patients were assigned for the study, and 419(97.7%) patients had the IPA dissected and recorded through photograph or video and were included in the primary outcome analysis. The median age was 62 years old, and 73.7% were male. Among the patients, 78.5% received laparoscopic surgery. Single IPA origination was identified in 398(95.0%) patients, including gastroduodenal artery(GDA) in154(36.8%) patients, anterior superior pancreaticoduodenal artery(ASPDA) in 130(31.0%) patients, and right gastroepiploic artery(RGEA) in 114(27.2%) patients. Fifteen(3.6%) patients were identified with multiple IPA and 6(1.4%) patients were identified as IPA absence. The differences in the distribution of surgical approach(P=0.003) and geographic area(P=0.030) were statistically significant. No difference was shown in sex, age,gastrectomy type, tumor location, and clinical T, N and M stage.Conclusions: Our study found that the IPA originates from GDA, ASPDA and RGEA in similar proportions.Laparoscopic surgery may be more helpful in dissection of the IPA than open surgery.Rulin Miao Jianjun Qu Zhengrong Li Daguang Wang Jiang Yu Weidong Zang Yong Li Fenglin Liu Jian Zhang Wu Song Kai Ye Su Yan Wei Wang Shuangyi Ren Lu Zang Changqing Jing Li Zhang Kuan Wang Weihua Fu Lin Fan Bin Liang Gang Zhao Jun Cai Li Yang Jiaming Zhu Jun You Kun Yang Qingxing Huang Zhaojian Niu Ning Ning Xingfeng Qiu Gang Ji Feng Liang Hua Huang Chao Gao Fei Shan Shuangxi Li Yongning Jia Lianhai Zhang Xiangji Ying Yan Zhang Zhaode Bu Xiangqian Su Gang Zhao Ziyu Li Jiafu Ji 2018Chinese Journal of Cancer Research2018,30,5:5
11Postoperative chemotherapy with S-1 plus oxaliplatin versus S-1alone in locally advanced gastric cancer(RESCUE-GC study): a protocol for a phase Ⅲ randomized controlled trial显示文摘Background:The ACTS-GC study had shown postoperative adjuvant therapy with S-1 improved survival of patients with locally advanced gastric cancer.Addition of oxaliplatin to S-1 is considered to be acceptable as one of the treatment options for gastric cancer patients after radical gastrectomy with D2 lymph node excision.Methods:We have commenced a randomized phase III trial in December 2016 to evaluate S-1 plus oxaliplatin compared with S-1 alone in the adjuvant setting for locally advanced gastric cancer.A total of 564 patients will be accrued from 13 Chinese institutions in two years.The primary endpoint is 3-year relapse-free survival.The secondary endpoints are 5-year overall survival,proportion of patients who complete the postoperative chemotherapy and incidence of adverse events.Ethic and dissemination:The trial has been approved by the institutional review board of each participating institution and it was activated on December,2016.The enrollment will be finished in December,2018.Patient’s follow-up will be ended until December,2023.Trial registration:Clinical Trials.gov,identifier:NCT02867839.Registered on August 4,2016.Xiang Hu Lin Chen Yian Du Biao Fan Zhaode Bu Xin Wang Yingjiang Ye Zhongtao Zhang Gang Xiao Fei Li Qingsi He Guoli Li Xian Shen Bin Xiong Liming Zhu Jiwei Liui Lian Liu Tao Wu Jing Zhou Jun Zhang Gang Zhao Xulin Wang Pin Liang Xinxin Wang Yan Zhang Xiaojiang Wu Ji Zhang Xin Ji Xianglong Zong Tao Fu Ziyu Jia Jiafu Ji 2017Chinese Journal of Cancer Research2017,29,2:5
12Germline mutations in hereditary diffuse gastric cancer显示文摘Gastric cancer is one of the leading causes of cancer-related deaths worldwide. Among which, about 1%–3% of gastric cancer patients were characterized by inherited gastric cancer predisposition syndromes, knowing as hereditary diffuse gastric cancer(HDGC). Studies reported that CDH1 germline mutations are the main cause of HDGC. With the help of rapid development of genetic testing technologies and data analysis tools, more and more researchers focus on seeking candidate susceptibility genes for hereditary cancer syndromes. In addition, National Comprehensive Cancer Network(NCCN) guidelines recommend that the patients of HDGC carrying CDH1 mutations should undergo prophylactic gastrectomy or routine endoscopic surveillances. Therefore, genetic counseling plays a key role in helping individuals with pathogenic mutations make appropriate risk management plans. Moreover, experienced and professional genetic counselors as well as a systematic multidisciplinary team(MDT) are also required to facilitate the development of genetic counseling and benefit pathogenic mutation carriers who are in need of regular and standardized risk management solutions. In this review, we provided an overview about the germline mutations of several genes identified in HDGC, suggesting that these genes may potentially act as susceptibility genes for this malignant cancer syndrome. Furthermore, we introduced information for prevention, diagnosis and risk management of HDGC. Investigations on key factors that may have effect on risk management decision-making and genetic data collection of more cancer syndrome family pedigrees are required for the development of HDGC therapeutic strategies.Hao Zhang Mengmeng Feng Yi Feng Zhaode Bu Ziyu Li Shuqin Jia Jiafu Ji 2018Chinese Journal of Cancer Research2018,30,1:4
13Diagnostic value of negative enrichment and immune fluorescence in situ hybridization for intraperitoneal free cancer cells of gastric cancer显示文摘Objective:To explore the intraperitoneal free cancer cell(IFCC)detection value of negative enrichment and immune fluorescence in situ hybridization(NEimFISH)on chromosomes(CEN)8/17.Methods:To verify the reliability of NEimFISH,29 gastric cancer tumors,their adjacent tissues and greater omental tissues were tested.Our study then included 105 gastric cancer patients for IFCC.We defined patients as IFCC-positive if a signal was detected,regardless of the detailed cancer cell numbers.A comparison of clinicopathological features was conducted among IFCC groups.We also compared the diagnosis value and peritoneal recurrence predictive value among different detection methods.The comparison of IFCC number was also conducted among different groups.Results:A cutoff of 2.5 positive cells could distinguish all benign tissue samples and 97%of malignant tissue samples in our study.Compared to intestinal gastric cancer,patients with diffuse gastric cancer tended to have more IFCCs(6 vs.4,P=0.002).The IFCC counts were often higher in the lymphovascular invasion positive group than negative group(3 vs.1,P=0.022).All IFCC samples that were considered positive using conventional cytology were also found to be positive using NEimFISH.When compared to conventional cytology and paraffin pathology,NEimFISH had a higher IFCC positive rate(68.9%)and higher one-year peritoneal recurrence predictive value with area under the curve(AUC)of 0.922.Conclusions:Gastric cancer could be effectively diagnosed by NEimFISH.The IFCC number found using NEimFISH on CEN8/17 is closely associated with Lauren type and vascular invasion of cancer.NEimFISH is a reliable detection modality with a higher positive detection rate,higher one-year peritoneal recurrence predictive value and quantitative features for IFCC of gastric cancer.Anqiang Wang Zhongwu Li Qian Wang Yali Bai Xin Ji Tao Fu Ke Ji Yanwen Xue Tingxu Han Xiaojiang Wu Ji Zhang Yingjie Yang Guobin Xu Zhaode Bu Jiafu Ji 2019Chinese Journal of Cancer Research2019,31,6:3
14A commentary on:“A pan-cancer single-cell transcriptional atlas of tumor infiltrating myeloid cells”–tumor microenvironment:the Achilles heel of cancer显示文摘Significance of tumor microenvironment(TME)to cancer Cancer is a complicated disease.With the deepening of the research on the mechanism of tumor initiation,promotion and progression in recent years,researchers have gradually shifted their focus from tumor itself to TME.The concept of TME can be traced back to the relationship between tumor and inflammation and the theory of“seed and soil”in the latter half of the nineteenth century[1].TME consists of non-malignant cells,vessels,lymph nodes,nerves,intercellular components,and metabolites located at the center,margin,or periphery of the tumor[1].There is increasing evidence that cellular and non-cellular components of the TME can promote tumor initiation,growth,invasion,metastasis,and response to treatment.The TME is composed of three main cell types:immune cells,stromal cells(e.g.cancer-associated fibroblasts),vascular cells[2,3].Jingtao Wei Zhaode Bu Jiafu Ji 2021Medical Review2021,1,2:3
15Clinicopathological and prognostic differences between mucinous gastric carcinoma and signet-ring cell carcinoma显示文摘Objective: To analyze the differences in clinicopathologic characteristics and prognosis between mucinous gastric carcinoma (MGC) and signet-ring cell carcinoma (SRCC). Methods: Clinicopathologic and prognostic data of 1,637 patients with histologically confirmed MGC or SRCC who received surgical operations in the Department of Gastroenterological Surgery, Beijing Cancer Hospital between December 2004 and December 2009 were retrospectively collected and analyzed. The clinicopathological features were analyzed statistically using χ 2 test. Survival was analyzed using the Kaplan-Meier method and multivariate analysis of Cox proportional hazards regression model (backward, stepwise). Results: A total of 181 patients with gastric cancer (74 MGC, 107 SRCC) were included. MGC, when compared with SRCC, was featured by senile patients, stage III and IV, upper third stomach, large tumor size, positive lymph node metastasis, and positive lymphatic vascular invasion (P<0.05). The overall 5-year survival rate showed no difference between the two groups (48.8% vs. 44.8%, P>0.05). However, the survival rate for MGC patients was significant lower than that for SRCC patients when compared among the age <60 years, negative distant metastasis, and tumor localized at upper third stomach (P<0.05). Multivariate Cox proportional hazards models revealed that distant metastasis was a significant independent prognostic indicator in MGC group, and lymph node metastasis and distant metastasis was significant independent prognostic indicators in SRCC group. Conclusions: While compared with SRCC, MGC is associated with a more aggressive tumor biologic behavior. There is no statistically significant difference in distant metastasis, an independent prognostic indicator for both MGC and SRCC, which might be the reason for no significant difference of the overall survival rate between the patients with MGC and SRCC.Zhaode Bu Zhixue Zheng Ziyu Li Xiaojiang Wu Lianhai Zhang Aiwen Wu Xianglong Zong Jiafu Ji 2013Chinese Journal of Cancer Research2013,25,1:3

17Laparoscopic vs.open lower mediastinal lymphadenectomy for Siewert typeⅡ/Ⅲadenocarcinoma of esophagogastric junction:An exploratory,observational,prospective,IDEAL stage2b cohort study(CLASS-10 study)显示文摘Objective:This study aims to verify the feasibility and efficacy of laparoscopic lower mediastinal lymphadenectomy for Siewert typeⅡ/Ⅲadenocarcinoma of esophagogastric junction(AEG).Setting:An exploratory,observational,prospective,cohort study will be carried out under the Idea,Development,Exploration,Assessment and Long-term Follow-up(IDEAL)framework(stage 2 b).Paritcipants:The study will recruit 1,036 patients with cases of locally advanced AEG(Siewert typeⅡ/Ⅲ,clinical stage cT2-4 aN0-3 M0),and 518 will be assigned to either the laparoscopy group or the open group.Interventions:Patients will receive lower mediastinal lymphadenectomy along with either total or proximal gastrectomy.Primary and secondary outcome measures:The primary endpoint is the number of lower mediastinal lymph nodes retrieved,and the secondary endpoints are the surgical safety and prognosis,including intraoperative and postoperative lower-mediastinal-lymphadenectomy-related morbidity and mortality,rate of rehospitalization,R0 resection rate,3-year local recurrence rate,and 3-year overall survival.Conclusions:The study will provide data for the guidance and development of surgical treatment strategies for AEG.Trial registration number:The study has been registered in ClinicalTrials.gov(No.NCT04443478).Shuangxi Li Xiangji Ying Fei Shan Yongning Jia Zhemin Li Kan Xue Rulin Miao Yinkui Wang Zhaode Bu Xiangqian Su Ziyu Li Jiafu Ji 2022Chinese Journal of Cancer Research2022,34,4:3
18Comments on Chinese guidelines for diagnosis and treatment of gastric cancer 2018(English edition)显示文摘Gastric cancer remains one of the most important malignancies in the world,with more than 1,000,000 new cases and an estimated 783,000 deaths in 2018,making it the fifth most frequently diagnosed cancer and the third leading cause of cancer death.Unfortunately,most of these cases occurred in Asia,especially in China(1).Gastric cancer causes more than 200 billion CNY of direct and indirect economic losses in China annually.Over the past decades,China has made great progress in the prevention and treatment of gastric cancer,but it is still a relatively prominent health problem,which has brought a huge burden to people's health and social economy.Zhaode Bu Jiafu Ji 2020Chinese Journal of Cancer Research2020,32,4:2
19Comments on National guidelines for diagnosis and treatment of gastric cancer 2022 in China(English version)显示文摘Gastric cancer is one of the most common malignancies in China.According to the latest statistics in 2020,the incidence and mortality of gastric cancer all rank the third among all cancers,which have brought a huge burden to people’s health and social economy.Besides the high morbidity and mortality,the low early diagnosis rate is another dilemma of gastric cancer in China.Early gastric cancer accounts for only 20%of new gastric cancer cases in China.Most cases are already in the advanced stage when discovered,and the overall 5-year survival rate is less than50%(1,2).Over the past decades,China has made great progress in the prevention and treatment of gastric cancer,but it is still a relatively prominent health problem.Jiahui Chen Zhaode Bu Jiafu Ji 2022Chinese Journal of Cancer Research2022,34,5:2
20Identification of lymph node metastasis by computed tomography in early gastric cancer显示文摘Objective:Lymph node status is critical when selecting treatment methods for patients with early gastric cancer(EGC).The aim of this study was to assess the diagnostic value of computed tomography(CT)for detection of lymph node metastasis(LNM)in patients with EGC.Methods:We retrospectively analyzed patients who had pathologically confirmed EGC between November2010 and January 2019.After 1:1 propensity score matching,65 patients with LNM and 65 patients without LNM were retained for comparison.The long diameter(LD)and short diameter(SD)of all visualized lymph nodes in all stations were recorded.The diagnostic value of LNM was assessed with receiver operating characteristic analysis.Results:Among 130 patients,we found a total of 558 lymph nodes on the CT images.Among the diagnostic indicators,the number,sum of LD and sum of SD of lymph nodes greater than 3 mm had better discrimination.The areas under the curve were all greater than 0.75.As for different regions,the optimal cutoff values of number,the sum of LD and sum of SD were determined as follows:overall,≥4,19.9 mm and 13.5 mm;left gastric artery basin,≥3,15.7 mm and 8.6 mm;right gastroepiploic artery basin,≥2,8.6 mm and 7.0 mm.Conclusions:CT is valuable for diagnosing LNM in EGC patients.The number,sum of LD and sum of SD of lymph nodes greater than 3 mm are preferable indicators.Different regional lymph nodes have different optimal criteria for predicting LNM in ECG patients.Jingtao Wei Yinan Zhang Zhilong Wang Xiaojiang Wu Ji Zhang Zhaode Bu Jiafu Ji 2021Chinese Journal of Cancer Research2021,33,6:2
