Albumin to gamma-glutamyltransferase ratio (AGR) is a newly developed biomarker for the prediction of patients’ prognosis in solid tumors. The purpose of the study was to establish a novel AGR-based nomogram to predict tumor prognosis in patients with early-stage HCC undergoing radiofrequency ablation (RFA). 394 hepatocellular carcinoma (HCC) patients who had received RFA as initial treatment were classified into the training cohort and validation cohort. Independent prognostic factors were identified by univariate and multivariate analyses. The value of AGR was evaluated by the concordance index ( C -index), receiver operating characteristic (ROC) curves, and likelihood ratio tests (LAT). Logistic regression and nomogram were performed to establish the pretreatment scoring model based on the clinical variables. As a result, AGR = 0.63 was identified as the best cutoff value to predict overall survival (OS) in the training cohort. According to the results of multivariate analysis, AGR was an independent indicator for OS and recurrence-free survival (RFS). In both training cohort and validation cohort, the high-AGR group showed better RFS and OS than the low-AGR group. What is more, the C -index, area under the ROC curves, and LAT χ 2 values suggested that AGR outperformed the Child-Pugh (CP) grade and albumin-bilirubin (ALBI) grade in terms of predicting OS. The AGR, AKP, and tumor size were used to establish the OS nomogram. Besides, the results of Hosmer-Lemeshow test and calibration curve analysis displayed that both nomograms in the training and validation cohorts performed well in terms of calibration. Therefore, the AGR-based nomogram can predict the postoperative prognosis of early HCC patients undergoing RFA.

Background: Testicular Germ Cell Tumor (TGCT) is the most common malignant tumor in young men, but there is a lack of prediction model to evaluate prognosis of patients with TGCT. Objective: To explore the prognostic factors for Progression-Free Survival (PFS) and construct a nomogram model for patients with early-stage TGCT after radical orchiectomy. Methods: Patients with TGCT from The Cancer Genome Atlas (TCGA) database were used as the training cohort; univariate and multivariate cox analysis were performed. A nomogram was constructed based on the independent prognostic factors. Patients from the Nanfang Hospital affiliated with Southern Medical University were used as the cohort to validate the predictive ability using the nomogram model. Harrell's concordance index (C-index) and calibration plots were used to evaluate the nomogram. Results: A total of 110 and 62 patients with TGCT were included in training cohort and validation cohort, respectively. Lymphatic Vascular Invasion (LVI), American Joint Committee on Cancer (AJCC) stage and adjuvant therapy were independent prognostic factors in multivariate regression analyses and were included to establish a nomogram. The C-index in the training cohort for 1-, 3-, and 5-year PFS were 0.768, 0.74 and 0.689, respectively. While the C-index for 1-, 3-, and 5-year PFS in the external validation cohort were 0.853, 0.663 and 0.609, respectively. The calibration plots for 1-, 3-, and 5-year PFS in the training and validation cohort showed satisfactory consistency between predicted and actual outcomes. The nomogram revealed a better predictive ability for PFS than AJCC staging system. Conclusion: The nomogram as a simple and visual tool to predict individual PFS in patients with TGCT could guide clinicians and clinical pharmacists in therapeutic strategy.

The Difference

4581 Background: In parallel with a multicenter randomized controlled trial that reported an equal recurrence-free survival (RFS) of early-stage hepatocellular carcinoma (HCC) patients who underwent either surgery (SUR) or radiofrequency ablation (RFA), we also enrolled HCC patients who fulfilled the enrollment criteria but did not give consent to participate in the RCT. Methods: All patients gave informed consent to participate in this study. Inclusion criteria were as follows: primary HCC with less than or equal to 3 tumors, each measuring 3 cm or smaller; without vascular invasion or extrahepatic metastasis; Child-Pugh score of 7 or less; and ages between 20 and 79 years. The feasibility for both treatments was confirmed by a joint chart review by surgeons and hepatologists. The primary endpoint was RFS and overall survival. A pre-specified interim analysis was performed to compare RFS. Results: Between April 2009 and August 2015, 740 patients (371 in SUR, 369 in RFA) were enrolled from 49 participating hospitals in Japan. The SUR group had significantly fewer patients with chronic hepatitis C (56.6% vs. 69.4%), higher median value of platelet count (145 vs. 120 × 109/L), and more patients with > 2 cm tumors (49.9% vs. 27.9%); most patients had a single tumor (91.1% vs. 88.3%). During the median follow-up period of 5 years, tumor recurrence was observed in 192 of SUR and 218 of RFA with 3-year RFS being 66.0% and 61.7%, respectively ( P = 0.091). In subgroup analysis, RFS was significantly better in SUR in patients with ≤ 2 cm tumors (62.9% vs. 51.7% in 3 years; hazard ratio [HR] 0.72, 95% confidence interval [CI] 0.56-0.93; P = 0.014), whereas the difference was not significant in those with > 2 cm tumors (52.7% vs. 46.4%; HR 0.85, 95% CI 0.63-1.18; P = 0.34). The adjusted HR for RFS using inversed probability of treatment weighting was 0.89 (95% CI, 0.72-1.10; P = 0.287). Conclusions: The imbalance in patient characteristics reflected a real-world practice. Factors related to background liver disease rather than tumor characteristics might have a larger impact on the recurrence in early HCC. Clinical trial information: C000001796 .

Objectives: The aim of this study was to compare the clinical effectiveness and cost of percutaneous radiofrequency ablation (PRFA) and surgical resection (SRS) for the management of early stage Hepatocellular Carcinoma.Methods: A systematic literature search of articles in English, French, and Chinese was performed using online databases. Only articles with patients classified as Child-Pugh Class A or B, with tumor size <5 cm were included. A meta-analysis was carried out to estimate the survival rate and disease-free survival rate following PRFA or SRS treatments. The cost of each treatment was estimated from the third party perspective. Univariate sensitivity analyses were used to study the relative importance of each component cost.Results: We identified six studies (one randomized controlled trial (RCT) and five comparative cohort studies) meeting our inclusion criteria. There is good evidence that among Child-Pugh A patients for whom both SRS and PRFA are available options, survival rates following either procedure are comparable, while complications are more frequent and hospitalization longer following SRS. The evidence concerning recurrence rates and disease-free survival is less clear. Whereas the RCT indicates comparable outcomes with either procedure up to 3 years, the results of five cohort studies (with possible selection bias), particularly those with a mix of Child-Pugh A and B patients, favor the surgical option. SRS, costs approximately Canadian $8,275 more per case than PRFA.Conclusions: Continuing doubts on this issue can only be resolved by a substantial RCT. Meanwhile, for early stage HCC patients classified as Child-Pugh A, who despite a possibly higher recurrence rate, prefer the less invasive PRFA to open surgery with its attendant risks, there is sufficient evidence to justify such a choice. For those classified as Child-Pugh (B) it is possible that overall survival is equally good with PRFA, but the evidence is less certain.

Abstract Background. Liver resection is effective for hepatocellular carcinoma (HCC). For a single HCC in subsegment 6 (S6), segmentectomy of S6, S5 (S6+5) and segmentectomy of S6, S7 (S6+7) are the common anatomical surgical procedures. However, the benefit of the two resection methods has not been clarified in this patient subgroup. This study aimed to compare the outcomes of S6+5 resection and S6+7 resection for single, early HCC located on S6 of the liver. Methods. In total, 115 patients with single HCC in S6 without vascular invasion and distant metastasis were included in this study. The patients were divided into the S6+5 group (n=73) and S6+7 group (n=42). A one-to-one propensity score-matching analysis (PSM) was performed to minimize the effect of potential confounders. Results. Forty patients from each group were matched. The preoperative factors were balanced between the two groups. The 1-, 2-, and 3-year overall survival (OS) rates in the S6+5 group were 92.3%, 82.1%, and 76.8%, respectively, and in the S6+7 group were 94.5%, 91.6% and 88.6%, respectively (p=0.197). The 1-, 2-, and 3-year recurrence-free survival (RFS) rates in the S6+5 group were 71.9%, 61.6%, and 58.9%, respectively, and in the S6+7 group were 83.5%, 77.7% and 68.8%, respectively (p=0.432). There were no significant differences in the recurrence pattern and postoperative recovery of liver function. The surgical procedure was not a significant risk factor for the OS and RFS in both the uni- and multivariate analyses. Conclusion. S6+5 and S6+7 resection achieved similar outcomes for early-stage solitary HCC in S6.

e14578 Background: Microsatellite stability (MSS) tumors hardly benefit from immunotherapies and are more probable to occur postoperative recurrence. However, some studies have revealed that a subset of MSS patients harbor “hot immune microenvironment” tumors, indicating high heterogeneity in such wide range of patient population. On the other hand, researches of mechanism of MSI formation found potential similarities in endometrial and gastrointestinal tumors. We hypothesized the transcriptomic features in these cancers correlated with immune-related signatures and patients’ prognosis. Methods: Early stage (I-III stage) MSS tumors, including endometrial, colorectal, and gastric from TCGA project were analyzed as training cohort (n=170). A combined cohort consisting of 604 colorectal and stomach cancers from GEO datasets (GSE39582，GSE62254) was validation cohort. The RNA-Seq profiling data and disease-free survival (DFS) data of patients were collected. Cibersort tool was used to evaluate twenty-two immune cells’ enrichment. The prediction model was developed by three steps: Univariate cox regression of DFS was conducted to select 9 immune cells. Then the train cohort was divided into two groups based on non-negative matrix factorization (NMF) method using this 9 immune cell features. Differentially expressed genes of these two groups were identified and screened further by lasso regression. Log-rank test was used to evaluate the difference of DFS. Results: A six-gene lasso-cox model was developed. The genes were LYZ, WFDC2, CAPS, RHPN1, TFF2 and TGFBR2. Based on the score evaluated by this model, patients in training cohort were divided into high-risk and low-risk groups. Low-risk population had much longer DFS (HR 0.07, 95%CI 0.03-0.18, p<0.001). In validation cohort, lower risk score was also verified to be associated with a lower likelihood of recurrence (HR 0.66, 95%CI 0.5-0.88, p=0.0047). Conclusions: We developed a model of six-genes predicting disease-free survival based on RNA-Seq data in early stage MSS patients. Further validation was needed to implement in larger clinical cohorts.

Abstract Background Repeat hepatectomy and radiofrequency ablation (RFA) are widely used to treat early recurrent hepatocellular carcinoma (RHCC) located in the subcapsular region, but the optimal treatment strategy remains to be controversial. Methods A total of 126 RHCC patients in the subcapsular location after initial radical hepatectomy were included in this study between Dec 2014 and Jan 2018. These patients were divided into the RFA group (46 cases) and the repeat hepatectomy group (80 cases). The primary endpoints include repeat recurrence-free survival (rRFS) and overall survival (OS), and the secondary endpoint was complications. The propensity-score matching (PSM) was conducted to minimize the bias. Complications were evaluated using the Clavien-Dindo classification, and severe complications were defined as classification of complications of ≥grade 3. Results There were no significant differences in the incidence of severe complications were observed between RFA group and repeat hepatectomy group in rRFS and OS both before (1-, 2-, and 3-year rRFS rates were 65.2%, 47.5%, and 33.3% vs 72.5%, 51.2%, and 39.2%, respectively, P = 0.48; 1-, 2-, and 3-year OS rates were 93.5%, 80.2%, and 67.9% vs 93.7%, 75.8%, and 64.2%, respectively, P = 0.92) and after PSM (1-, 2-, and 3-year rRFS rates were 68.6%, 51.0%, and 34.0% vs 71.4%, 42.9%, and 32.3%, respectively, P = 0.78; 1-, 2-, and 3-year OS rates were 94.3%, 82.9%, and 71.4% vs 88.6%, 73.8%, and 59.0%, respectively, P = 0.36). Moreover, no significant differences in the incidence of severe complications were observed between the RFA group and repeat hepatectomy group. Conclusion Both repeat hepatectomy and RFA are shown to be effective and safe for the treatment of RHCC located in the subcapsular region.

e16115 Background: In the past clinical practice of radiotherapy for liver cancer, liver regeneration (LR) which is beneficial to the prevention or recovery of radiation-induced liver injury, has not received enough attention. In current study, we aimed to build and validate multivariate model for liver regeneration after radiation therapy for hepatocellular carcinoma (HCC) based on data from 2 prospective studies. Methods: Thirty patients treated with preoperative downstaging radiotherapy were prospectively included in the training cohort, and 21 patients treated with postoperative adjuvant radiotherapy were included in the validation cohort. Liver regeneration was defined as an increase of more than 10% of normal liver volume in the areas of the protected hepatic segment or lobe, without Child-Pugh class decreased and tumor progression compared to pre-radiotherapy. Model and nomogram of liver regeneration after radiotherapy were developed and validated. The cut-off points of each optimal predictors were obtained using receiver-operating characteristic analysis. Risk stratification based on the cut-off point was conducted to compare the proportion of patients with liver regeneration between subgroups. Results: After radiotherapy, 12 (40%) cases in the training cohort and 13 (61.9%) cases in the validation cohort experienced liver regeneration. The model and nomogram of liver regeneration based on SVs20 (standard residual liver volume spared from at least 20 Gy) and alanine aminotransferase (ALT) showed good prediction performance (AUC = 0.759) in training cohort and performed well (AUC = 0.808) in the validation cohort. The risk stratification according to the cutoffs of SVs20 with 303.4 mL and ALT with 43 U/L demonstrated clear differentiation in risk of liver regeneration between the training(P = 0.049) and entire cohort (P = 0.032). The proportion of patients with liver regeneration decrease progressively with 88.9% in high-probability group (ALT＜43 U/L and SVs20＜303.4 mL), 60% in high-intermediate probability group (ALT ≥43 U/L and SVs20＜303.4 mL), 43.75% in low-intermediate probability group (ALT＜43 U/L and SVs20≥303.4 mL) and 33% in low- probability group (ALT≥43 U/L and SVs20≥303.4 mL). Conclusions: SVs20 and ALT are optimal predictors for liver regeneration. This simple-to-use nomogram is beneficial to the constraints of normal liver outside the radiotherapy target area and make prognosis-based decision without complex calculations.
