31 Background: Survival outcomes are significant different in stage II colorectal cancer (CRC) patients with diverse clinicopathological features. Objective of this study is to establish a credible prognostic nomogram incorporating easily obtained parameters for stage II CRC patients. Methods: A total of 1708 stage II CRC patients at Fudan University Shanghai Cancer Center (FUSCC) during 2008 to 2013 were retrospectively analyzed in this study. Cases were randomly separated into training set (n = 1084) and validation set (n = 624). Univariate and multivariate Cox regression analyses were used to identify independent prognostic factors which were subsequently incorporated into a nomogram. The performance of the nomogram was evaluated by C-index and ROC curve to calculate the area under the curve (AUC). The clinical utility of the nomogram was evaluated using decision curve analysis (DCA). Results: In univariate and multivariate analyses, eight parameters were correlated with disease free survival (DFS), which were subsequently selected to draw prognostic nomogram based on DFS. For DFS predictions, the predicted concordance index (C-index) of the nomogram was 0.842 (95% confidence interval (CI), 0.710-0.980), and 0.701 (95% CI, 0.610-0.770) for training and validation set, respectively. The AUC values of ROC predicted 1, 3 and 5-year survival of nomogram in the training and validation groups were 0.869, 0.858, 0.777 and 0.673, 0.714, 0.706, respectively. The recurrence probability calibration curve showed good consistency between actual observations and nomogram-based predictions. DCA showed better clinical application value for the nomogram compared with TNM staging system. Conclusions: A novel nomogram based on a large population study was established and validated, which is a simple-to-use tool for physicians to facilitate the postoperative personalized prognostic evaluation and determine therapeutic strategies for stage II CRC patients.

Abstract Background Lymphovascular invasion (LVI) is defined as the presence of cancer cells in lymphatics or blood vessels. This study aimed to evaluate the prognostic value of LVI in stage II colorectal cancer (CRC) patients with inadequate examination of lymph nodes (ELNs) and further combined LVI with the TNM staging system to determine the predictive efficacy for CRC prognosis. Adjuvant chemotherapy (ACT) was then evaluated for stage II CRC patients with LVI positivity (LVI+). Methods In order to avoid the effects of different ACT regimens, among 409 stage II patients, we chose 121 patients who received FOLFOX regimen and the 144 patients who did not receive ACT as the object of study. LVI was examined by hematoxylin-eosin (HE) staining. Kaplan-Meier analysis followed by a log-rank test was used to analyze survival rates. Univariate and multivariate analyses were performed using a Cox proportional hazards model. Harrell’s concordance index (C-index) was used to evaluate the accuracy of different systems in predicting prognosis. Results The LVI+ status was significantly associated with pT stage, degree of differentiation, tumor stage, serum CEA and CA19-9 levels, perineural invasion (PNI), tumor budding (TB), and KRAS status. The 5-year overall survival (OS) rate of stage II patients with < 12 ELNs and LVI+ was less than stage IIIA. Multivariate analyses showed that LVI, pT-stage, serum CEA and CA19-9 levels, PNI, TB, and KRAS status were significant prognostic factors for stage II patients with < 12 ELNs. The 8th TNM staging system combined with LVI showed a higher C-index than the 8th TNM staging system alone (C-index, 0.895 vs. 0.833). Among patients with LVI+, the ACT group had a significantly higher 5-year OS and 5-year disease-free survival (DFS) than the surgery alone (SA) group (5-year OS, 66.7% vs. 40.9%, P = 0.004; 5-year DFS, 64.1% vs. 36.3%, P = 0.002). Conclusions LVI is an independent prognostic risk factor for stage II CRC patients. Combining LVI with the 8th TNM staging system improved the predictive accuracy for CRC prognosis. ACT in stage II CRC patients with LVI+ is beneficial for survival.

516 Background: We proposed T-plus staging system which abandon the criterion to discriminate stage II/III by lymph node status and strengthens weighting of the T stage according to cluster analysis of the summary survival data of SEER. In this study, this principle of the T-plus staging system was verified with single center data by nomogram analysis. Methods: The 1,099 patients with colorectal cancer diagnosed before 2005 were analyzed to build a novel staging system based on nomogram (nomo-staging system). The remaining 981 patients diagnosed after 2005 were used to test the performance of nomo-staging system, T-plus staging system and the 7th edition TNM staging system by Akaike information criteria (AIC), Harrell’s c-index and the area under the curve (AUC) of Receiver Operating Characteristic to predict 5-year overall survival. A smaller AIC, higher c-index and higher AUC indicated a better staging system. Results: The nomo-staging system and T-plus staging system were listed in Table 1. The validation found that the 7th edition TNM staging system showed the weakest performance. For AIC, both nomo-staging system and T-plus staging system showed smaller value than the 7th edition TNM staging system (3214.912 vs. 3224.643 vs. 3229.810). For Harrell’s c-index, both the T-plus staging system and nomo-staging system showed higher value than the 7th edition TNM staging system (0.6814 vs. 0.6787 vs. 0.6778). For AUC to predict 5-year OS, the T-plus staging system and nomo-staging system showed slightly higher value than the 7th edition TNM staging system (0.6944 vs. 0.6924 vs. 0.6913). Conclusions: We propose replacement of lymph node status as the criterion to discriminate colorectal cancer stage II/III with greater weighting of the T stage. [Table: see text]

Abstract Purpose The present study aimed to identify independent clinicopathological and socio-economic prognostic factors associated with overall survival of early-onset colorectal cancer (EO-CRC) patients and then establish and validate a prognostic nomogram for patients with EO-CRC. Methods Eligible patients with EO-CRC diagnosed from 2010 to 2017 were extracted from the Surveillance, Epidemiology, and End Results (SEER) database. Patients were randomly divided into a training cohort and a testing cohort. Independent prognostic factors were obtained using univariate and multivariate Cox analyses and were used to establish a nomogram for predicting 3- and 5-year overall survival (OS). The discriminative ability and calibration of the nomogram were assessed using C-index values, AUC values, and calibration plots. Results In total, 5585 patients with EO-CRC were involved in the study. Based on the univariate and multivariate analyses, 15 independent prognostic factors were assembled into the nomogram to predict 3- and 5-year OS. The nomogram showed favorable discriminatory ability as indicated by the C-index (0.840, 95% CI 0.827–0.850), and the 3- and 5-year AUC values (0.868 and 0.84869 respectively). Calibration plots indicated optimal agreement between the nomogram-predicted survival and the actual observed survival. The results remained reproducible in the testing cohort. The C-index of the nomogram was higher than that of the TNM staging system (0.840 vs 0.804, P < 0.001). Conclusion A novel prognostic nomogram for EO-CRC patients based on independent clinicopathological and socio-economic factors was developed, which was superior to the TNM staging system. The nomogram could facilitate postoperative individual prognosis prediction and clinical decision-making.

8Th Edition

Background: The 8th edition of the American Joint Committee on Cancer/Union for International Cancer Control (AJCC/UICC) tumor-node-metastasis (TNM) staging system was released with major revisions. The purpose of this retrospective study was to investigate differences between the 7th and 8th editions of the AJCC/UICC TNM staging system and to compare the predictability of prognosis between the two staging systems with patients who underwent thyroidectomy for differentiated thyroid cancer (DTC) at a single institution. Methods: A total of 3238 patients underwent thyroid operation from January 2002 to December 2006 at Yonsei University Hospital (Seoul, Korea), of which 2294 with complete clinical data and sustained follow up were enrolled. Clinicopathologic features and TNM staging by applying the 7th and 8th editions of the AJCC/UICC were analyzed retrospectively by the complete review of medical charts and pathology reports of patients. Mean follow-up duration was 132.9 ± 27.9 months. Results: A significant number of T3 patients were downstaged to T1 (838, 36.5%) and T2 (122, 5.3%). After applying the 8th edition of the AJCC/UICC TNM staging system, the number of stage I patients increased significantly from 1434 (62.5%) to 2058 (89.7%), whereas numbers of stage III and IV patients decreased significantly from 644 (28.1%) to 33 (1.4%) and from 199 (8.7%) to 17 (0.7%), respectively. According to Kaplan–Meier survival analyses and values of the Harrell’s c-index and integrated area under the curve (iAUC), the 8th edition has significantly better predictive performance for disease-free survival (DFS) and disease-specific survival (DSS) than the 7th edition. Conclusions: A significant population was downstaged after applying the 8th edition of the AJCC/UICC TNM staging system, and the 8th edition provided significantly better accuracy in predicting DFS and DSS in patients with DTC.

Objective: We aimed to formulate and validate prognostic nomograms that can be used to predict the prognosis of patients with upper tract urothelial carcinoma (UTUC). Methods: By consulting the Surveillance, Epidemiology, and End Results (SEER) database, we identified patients who were surgically treated for UTUC between 2004 and 2013. Variables were analyzed in both univariate and multivariate analyses. Nomograms were constructed based on independent prognostic factors. The prognostic nomogram models were established and validated internally and externally to determine their ability to predict the survival of patients with UTUC. Results: A total of 4990 patients were collected and enrolled in our analyses. Of these, 3327 patients were assigned to the training set and 1663 to the validation set. Nomograms were effectively applied to predict the 3- and 5-year survivals of patients with UTUC after surgery. The nomograms exhibited better accuracy for predicting overall survival (OS) and cancer-specific survival (CSS) than the tumor-node-metastasis (TNM) staging system and the SEER stage in both the training and validation sets. Calibration curves indicated that the nomograms exhibited high correlation to actual observed results for both OS and CSS. Conclusions: The nomogram models showed stronger predictive ability than the TNM staging system and the SEER stage. Precise estimates of the prognosis of UTUC might help doctors to make better treatment decisions.
