淋巴结转移是胃癌主要转移方式之一,区域淋巴结状态是判断胃癌生物学行为的重要参考指标,淋巴结转移分期是预测胃癌预后最主要的临床病理参数之一.自第5版AJCC胃癌TNM分期系统发表以来,大多数学者的研究报道以转移淋巴结数量(metastatic lymph node number,pN)为基础的N分期系统比以淋巴结解剖位置为基础的分期系统能更好地评估胃癌患者的预后[1,2].自第7版TNM分期系统应用以来,随着N分期标准的细化,许多学者研究认为此分期系统中的N分期较之前的第5、6版在评价胃癌预后方面更加优越[3,4].  相似文献

Background

The 8th edition of AJCC TNM staging manual for gastric cancer (GC) has been validated by several studies. A modified staging system based on it and total harvested number of lymph nodes (LNs; cutoff: 30) is suggested to improve predictive capacities for advanced GC. This study is designed to validate the modified method using a single-center database in Southern China.

Methods

Clinical data from 684?GC patients with stage II and III according to the 7th edition between 2001 and 2012 were reviewed. A modified staging system was applied to restage the cohort. The three staging systems were compared in terms of prognostic performance on long-term survival.

Results

The median follow-up period of this cohort was 52 (range, 6–180) months, with a median 5-year overall survival rate of 52.4%. Stage migration was observed in 159 (23.2%) patients according to the 8th edition of TNM staging, and another migration was observed in 108 (15.8%) patients according to the modified TNM staging system. Compared with the modified staging system, both 7th and 8th edition of AJCC TNM staging systems did not prove survival concordance on stage IIIA (7th edition) and stage IIIC (8th edition) when <30 LNs were examined. The survival performance between two AJCC staging systems had no significant improvement (c-index, 0.607 vs. 0.609), with the best prognostic stratification obtained using the modified staging method (c-index, 0.631).

Conclusions

The modified staging system on basis of the 8th AJCC classification and the number of harvested LNs could provide an optimal predictive capacities for advanced gastric cancer.  相似文献

Objective:We retrospectively analyzed the clinical prognostic value of the 8th edition of the American Joint Committee on Cancer (AJCC) staging system for luminal A breast cancer.Methods:Using both the anatomic and prognostic staging in the 8th edition of AJCC cancer staging system,we restaged patients with luminal A breast cancer treated at the Breast Disease Center,Peking University First Hospital from 2008 to 2014.Follow-up data including 5-year disease free survival (DFS),overall survival (OS) and other clinic-pathological data were collected to analyze the differences between the two staging subgroups.Results:This study included 421 patients with luminal A breast cancer (median follow-up,61 months).The 5-year DFS and OS rates were 98.3% and 99.3%,respectively.Significant differences in 5-year DFS but not OS were observed between different anatomic disease stages.Significant differences were observed in both 5-year DFS and OS between different prognostic stages.Application of the prognostic staging system resulted in assignment of 175 of 421 patients (41.6%) to a different group compared to their original anatomic stages.In total,102 of 103 patients with anatomic stage ⅡA changed to prognostic stage ⅠB,and 24 of 52 patients with anatomic stage ⅡB changed to prognostic stage ⅠB,while 1 changed to prognostic stage ⅢB.Twenty-two of 33 patents with anatomic stage ⅢA were down-staged to ⅡA when staged by prognostic staging system,and the other 11 patients were down-staged to ⅡB.Two patients with anatomic stage ⅢB were down-staged to ⅢA.Among seven patients with anatomic stage ⅢC cancer,two were down-staged to ⅢA and four were down-staged to stage ⅢB.Conclusions:The 8th edition of AJCC prognostic staging system is an important supplement to the breast cancer staging system.More clinical trials are needed to prove its ability to guide selection of proper systemic therapy and predict prognosis of breast cancer.  相似文献

This study was aimed to validate the 5th and 6th editions of tumor-node-metastasis (TNM) system for patients with hepatocellular carcinoma (HCC), and attempted to improve prognostic stratification by modifying the 6th edition according to vascular invasion and tumor size. From 1986 to 2002, a total of 5,613 HCC cases from Kaohsiung Chang Gung Memorial Hospital in southern Taiwan were enrolled. The 6th edition was modified by dividing stage I into stages IA (single tumor, < or =2cm) and IB (single tumor, >2cm), and by dividing stage II into IIA (multiple tumors, none >5cm) and IIB (tumor with segmental macro vascular invasion). The Akaike information criteria (AIC), within a Cox proportional hazard regression model were used; lower AIC value indicated a better discriminatory ability for staging system. The 1-, 3-, 5-, and 7-year overall survival rates were 45.6, 25.9, 17.9, and 13.4%, respectively. Significant differences in survival curve existed in the 5th, 6th, and modified 6th edition TNM systems. For the modified 6th edition TNM, survival differed significantly between stages IA and IB, and between stage IIA and IIB. The AIC values of 5th (72,328), 6th (72,188), modified 6th (71,991) edition TNM system were decreasing. This investigation demonstrated better prognostic stratifications for the 6th edition than the 5th edition TNM staging system. Moreover, the modified 6th edition staging system demonstrated better prognostic prediction than the former two. Pretreatment staging and simple classification of current modified 6th edition TNM staging can be applied to all HCC patients and are clinically useful.  相似文献

Background

Recently, the 8th edition of the TNM classification of esophageal cancer has come up. The present study aims to compare the 7th and the proposed 8th edition of the AJCC/UICC TNM staging system for esophageal squamous cell carcinoma (ESCC).

Methods

A total of 1872 ESCC patients who underwent radical surgery with curative intent were analyzed retrospectively. Survival was analyzed using the Kaplan–Meier method, and values were compared using the log-rank test. Multivariate analysis was performed using the Cox proportional hazard model. The Akaike information criterion (AIC) and the concordance index (c-index) were applied to compare the two prognostic systems.

Results

On univariate analysis, the 7th staging system, the proposed 8th staging system, gender, age as well as adjuvant treatment were found to have significant association with overall survival (OS). In both the current staging system and the modified version, age and gender were independent prognostic factors in a multivariate analysis. The AIC value for the proposed 8th version was smaller than that for the 7th staging system; the c-index value for the proposed 8th version was larger than that for the 7th staging system. Subgroup analysis in patients with/without nodal metastasis obtained consistent results.

Conclusion

Based on the data from our single center, the proposed 8th AJCC staging system seems to be superior to the 7th AJCC staging system in terms of OS for patients with thoracic ESCC who underwent radical surgery.  相似文献
