Background: Sarcopenia is a significant predictor of perioperative adverse outcomes for a variety of malignancies and has significant negative effects on surgical and oncology outcomes. The development of sarcopenia is mainly attributed to aging, inactivity, poor nutrition, and decreased testosterone levels, which suggest a poor prognosis after surgery. Therefore, the primary objective of this systematic review and meta-analysis was to determine the effect of sarcopenia on postoperative survival in patients with oral squamous cell carcinoma. Methods: We systematically searched databases including PubMed, Embase, Cochrane Library, Medline and Web of Science from inception to 12 July 2023, to determine the prognostic value of sarcopenia in oral squamous cell carcinoma. The primary outcome was three-year survival, and secondary outcomes were one-year survival, five-year survival, infection and pneumonia within 30 days postoperatively. Original studies comparing postoperative outcomes in patients with sarcopenia and non-sarcopenia for oral squamous cell carcinoma curative therapy were met the eligibility criteria. We used Endnote X9 for the screening process and used RevMan 5.4.1 for our meta-analysis, all results in this study were performed using a random-effects model. QUIPS (Quality in Prognosis Studies) tools and GRADE (Grading of Recommendations, Assessment, Development and Evaluations) were used for risk of bias and quality of evidence assessment. Result: Ten original studies with 50611 patients met the inclusion criteria. Meta-analysis showed that patients with sarcopenia reduced three-year OS after surgery (OR = 0.73, 95% CI = 0.66-0.81, P < 0.00001). The one-year OS (OR = 0.71, 95% CI = 0.67-0.75, P < 0.00001) and five-year OS (OR = 0.60, 95% CI = 0.45-0.79, P = 0.0003) decreased significantly. Patients with sarcopenia had significantly increased 30-day postoperative mortality and an also increased risk of pneumonia (OR = 1.36, 95% CI = 1.24-1.49, P < 0.00001) and surgical site infection (OR = 2.49, 95% CI = 1.06-5.84, P = 0.04). Conclusion: Sarcopenia is associated with reduced survival in patients after curative resection. Meanwhile, 30-day mortality, postoperative pneumonia and surgical site infection were significantly higher than those in nonsarcopenic patients. Sarcopenia as an extremely important factor of postoperative adverse outcomes in OSCC patients need special attention.

Background: The close association between inflammation and the clinical outcomes of hepatocellular carcinoma (HCC) has been extensively documented. This study aims to analyze the association between a novel inflammatory indicator, the gamma-glutamyl transpeptidase to neutrophil ratio (GNR), and HCC prognosis following curative resection. Methods: A cohort of 204 eligible HCC cases were included. Based on an optimal cut-off value determined utilizing the X-tile software, patients were categorized into low- and high-GNR groups. The overall survival (OS) and recurrence-free survival (RFS) rates were assessed using the Kaplan-Meier analysis method with Log rank tests. Multivariate Cox proportional hazard regression was used to investigate the independent association between GNR and HCC prognosis. Restricted cubic splines were used to explore the nonlinear relationship between GNR and the risk of death or recurrence. Results: The low GNR group exhibited significantly higher 3-year OS and RFS rates than the high GNR group. Multivariate Cox analysis indicated that a high GNR level was independently associated with poor OS and RFS. A linear correlation between GNR and the risk of death, as well as a nonlinear inverted "U" shape correlation between GNR and the risk of recurrence, were observed. Conclusion: The findings provide evidence supporting the independent association of GNR with HCC prognosis. These results offer promise for enhancing prognosis assessments and guiding active monitoring strategies for patients with HCC post-curative resection. [ABSTRACT FROM AUTHOR]

Background: The Naples prognostic score (NPS) determined by the nutritional and inflammatory condition of an individual is attracting growing attention for predicting postoperative outcomes in a variety of malignancies. The study aimed to assess the clinical significance of a modified NPS (M-NPS) and establish and validate nomograms incorporating M-NPS in curative stage II-III colon cancer patients. Methods: We retrospectively analyzed 328 stage II-III colon cancer patients receiving radical surgical resection at our hospital from January 2011 to December 2016. Kaplan–Meier (KM) survival analysis and Cox regression analysis were executed for overall survival (OS) and cancer-specific survival (CSS). Independent predictive indicators were applied to develop nomograms. The model’s performance was evaluated using many different methods. Results: Of a total of 328 cases, 153 cases were in group 0, 145 in group 1, and 30 in group 2. In terms of OS or CSS, there were obvious differences between groups 0 and 1, and between groups 0 and 2. Age, obstruction, N stage, gross tumor type, and M-NPS group were independent prognostic indicators for OS, while obstruction, gross tumor type, M-NPS group, and N stage were independent predictive parameters for CSS. Furthermore, the training and validation sets were randomly allocated among a cohort of 328 patients. OS and CSS prediction nomograms were developed. In the training and validation cohort, the C-index and ROC analysis showed good discrimination, calibration curves exhibited an excellent level of consistency between model-predicted survival and actual survival outcomes, and DCA curves demonstrated good clinical performance. Conclusion: M-NPS is a reliable survival predictor in patients with curative stage II-III colon cancer. Nomograms incorporating M-NPS for OS and CSS have good predictive performance and clinical utility. [ABSTRACT FROM AUTHOR]

Background: The objective of this study was to investigate the association between pre-operative body mass index (BMI) and surgical infection in perihilar cholangiocarcinoma (pCCA) patients treated with curative resection. Methods: Consecutive pCCA patients were enrolled from four tertiary hospitals between 2008 and 2022. According to pre-operative BMI, the patients were divided into three groups: low BMI (≤18.4 kg/m2), normal BMI (18.5–24.9 kg/m2), and high BMI (≥25.0 kg/m2). The incidence of surgical infection among the three groups was compared. Multivariable logistic regression models were used to determine the independent risk factors associated with surgical infection. Results: A total of 371 patients were enrolled, including 283 patients (76.3%) in the normal BMI group, 30 patients (8.1%) in the low BMI group, and 58 patients (15.6%) in the high BMI group. The incidence of surgical infection was significantly higher in the patients in the low BMI and high BMI groups than in the normal BMI group. The multivariable logistic regression model showed that low BMI and high BMI were independently associated with the occurrence of surgical infection. Conclusions: The pCCA patients with a normal BMI treated with curative resection could have a lower risk of surgical infection than pCCA patients with an abnormal BMI. [ABSTRACT FROM AUTHOR]

Tumour morphology (tumour burden score (TBS)) and liver function (albumin‐to‐alkaline phosphatase ratio (AAPR)) have been shown to correlate with outcomes in intrahepatic cholangiocarcinoma (ICC). This study aimed to evaluate the combined predictive effect of TBS and AAPR on survival outcomes in ICC patients. We conducted a retrospective analysis using a multicentre database of ICC patients who underwent curative surgery from 2011 to 2018. The Kaplan–Meier method was employed to examine the relationship between a new index (combining TBS and AAPR) and long‐term outcomes. The predictive efficacy of this index was compared to other conventional indicators. A total of 560 patients were included in the study. Based on TBS and AAPR stratification, patients were classified into three groups. Kaplan–Meier curves demonstrated that 124 patients with low TBS and high AAPR had the best overall survival (OS) and recurrence‐free survival (RFS), while 170 patients with high TBS and low AAPR had the worst outcomes (log‐rank p < 0.001). Multivariate analyses identified the combined index as an independent predictor of OS and RFS. Furthermore, the index showed superior accuracy in predicting OS and RFS compared to other conventional indicators. Collectively, this study demonstrated that the combination of liver function and tumour morphology provides a synergistic effect in evaluating the prognosis of ICC patients. The novel index combining TBS and AAPR effectively stratified postoperative survival outcomes in ICC patients undergoing curative resection. [ABSTRACT FROM AUTHOR]

Background: The number of older patients with cancer has increased, and colorectal cancer is expected to be affected by this trend. This study aimed to compare prognostic factors, including nutritional and inflammation-based indices, between patients aged ≥ 70 and < 70 years following curative resection of stage I–III colorectal cancer. Patients and Methods: This study included 560 patients with stage I–III colorectal cancer who underwent curative resection between May 2010 and June 2018. A retrospective analysis was performed to identify prognosis-associated variables in patients aged ≥ 70 and < 70 years. Results: Preoperative low body mass index, high C-reactive protein/albumin ratio, and comorbidities were mainly associated with poor prognosis in patients aged ≥ 70 years. Tumor factors were associated with a poor prognosis in patients aged < 70 years. The C-reactive protein/albumin ratio was independently associated with poor overall survival and recurrence-free survival in those aged ≥ 70 years. The time-dependent area under the curve for the C-reactive protein/albumin ratio was superior to those of other nutritional and inflammation-based indices in most postoperative observation periods in patients aged ≥ 70 years. Conclusions: Tumor factors were associated with a poor prognosis in patients aged < 70 years. In addition to lymph node metastasis, preoperative statuses were associated with poor prognosis in patients aged ≥ 70 years. Specifically, the preoperative C-reactive protein/albumin ratio was independently associated with long-term prognosis in patients aged ≥ 70 years with stage I–III colorectal cancer after curative resection.

Abstract Background High tumor recurrence and dismal survival rates after curative intended resection for hepatocellular carcinoma (HCC) are still concerning. The primary goal was to assess predictive factors associated with disease-free (DFS) and overall survival (OS) in a subset of patients with HCC undergoing hepatic resection (HR). Methods Between 08/2004–7/2021, HR for HCC was performed in 188 patients at our institution. Data allocation was conducted from a prospectively maintained database. The prognostic impact of clinico-pathological factors on DFS and OS was assessed by using uni- and multivariate Cox regression analyses. Survival curves were generated with the Kaplan Meier method. Results The postoperative 1-, 3- and 5- year overall DFS and OS rates were 77.9%, 49.7%, 41% and 72.7%, 54.7%, 38.8%, respectively. Tumor diameter ≥ 45 mm [HR 1.725; (95% CI 1.091–2.727); p = 0.020], intra-abdominal abscess [HR 3.812; (95% CI 1.859–7.815); p

Abstract Background For chronic hepatitis B virus (HBV) infection patients, increasing evidence has demonstrated the effectiveness of expanding the indications and applicable population for antiviral therapy. However, the expanded indication of antiviral therapy for hepatocellular carcinoma (HCC) remains to be further explored. Methods 196 HBV-related HCC patients who received radical hepatectomy and nucleos(t)ide analogues (NAs) therapy at Sichuan Provincial People’s Hospital were enrolled in this study. HCC recurrence, overall survival (OS), early virological (VR) and biochemical responses (BR) of patients were compared between different NAs therapy and the use of anti-programmed cell death protein 1 (PD-1) therapy. Results NAs therapy at different timing of surgery was a strong independent risk factor for postoperative recurrence and overall mortality of HBV-related HCC patients.

Conclusions: Despite high postoperative recurrence rates, an acceptable long-term survival in patients after curative HR could be achieved. The Identification of parameters related to OS and DFS improves patient-centered treatment and surveillance strategies. [ABSTRACT FROM AUTHOR]

Background: For chronic hepatitis B virus (HBV) infection patients, increasing evidence has demonstrated the effectiveness of expanding the indications and applicable population for antiviral therapy. However, the expanded indication of antiviral therapy for hepatocellular carcinoma (HCC) remains to be further explored. Methods: 196 HBV-related HCC patients who received radical hepatectomy and nucleos(t)ide analogues (NAs) therapy at Sichuan Provincial People's Hospital were enrolled in this study. HCC recurrence, overall survival (OS), early virological (VR) and biochemical responses (BR) of patients were compared between different NAs therapy and the use of anti-programmed cell death protein 1 (PD-1) therapy. Results: NAs therapy at different timing of surgery was a strong independent risk factor for postoperative recurrence and overall mortality of HBV-related HCC patients. Furthermore, in HCC patients who received postoperative anti-PD-1 therapy, patients with HBV DNA < 1000 copy/mL had significantly better recurrence-free survival (RFS) and OS than those with HBV DNA ≥ 1000 copy/mL (HR: 7.783; P = 0.002; HR: 6.699; P < 0.001). However, the differences of RFS and OS rates between entecavir group and tenofovir disoproxil fumarate group were not statistically significant. Similar results were also observed in the rates of early VR, BR and combined VR and BR. Conclusion: Timely and reasonable preoperative NAs therapy showed clinical benefit in improving the prognosis of patients with HBV-related HCC, even in the case of normal alanine aminotransferase (ALT) level and negative hepatitis e antigen (HBeAg). Furthermore, a possible synergistic effect between antiviral therapy and anti-PD-1 therapy was founded and need further verification. [ABSTRACT FROM AUTHOR]

Abstract A 70‐year‐old man was diagnosed with early gastric cancer with ulcerative findings. Endoscopic submucosal dissection as an absolute indication was performed, and en bloc resection was achieved. Pathological examination revealed a well‐differentiated adenocarcinoma, 3 × 2 mm in size, intramucosal, with an ulcerative scar, no lymphovascular invasion, and a tumor‐free margin. We diagnosed it as a curative resection and followed up with annual endoscopy. Sixteen months after endoscopic submucosal dissection, esophagogastroduodenoscopy revealed a singular ulcer scar; however, serum carcinoembryonic antigen level was elevated. Computed tomography scan showed wall thickening of the gastric antrum and an irregular mass on the dorsal side. Additionally, 18F‐fluorodeoxyglucose positron emission tomography/coomputed tomography showed 18F‐fluorodeoxyglucose uptake in the gastric antrum, irregular mass, and liver. Endoscopic ultrasonography revealed an internally heterogeneous mass in the gastric antrum region extending from the submucosal layer to the muscularis propria layer. Using an endoscopic ultrasonography‐guided fine needle biopsy with a 22‐gauge needle for the mass, we diagnosed local recurrence with the submucosal tumor‐like appearance, lymph node metastasis, and liver metastases. Unfortunately, the patient died of gastric cancer 3 months after the diagnosis. Here, we report a rare case of local recurrence in the submucosal layer, lymph node metastasis, and liver metastases 16 months after curative endoscopic submucosal dissection.

Consequently, this study aimed to develop and validate a novel prognostic model capable of accurately predicting the prognosis of proliferative HCC after curative resection.Patients and Methods: This retrospective multicenter study included patients with solitary HCC who underwent curative liver resection from August 2014 to December 2020 (n = 816). Patients were stratified into either the proliferative HCC cohort (n = 259) or the nonproliferative HCC cohort (n = 557) based on histological criteria. Disease-free survival (DFS) was compared between the two groups before and after one-to-one propensity score matching (PSM). Of all the proliferative HCC patients, 203 patients were assigned to training cohort, and 56 patients were assigned to validation cohort. Univariate and multivariate analyses were performed in training cohort to identify risk factors associated with worse DFS. Thereafter, a predictive model was constructed, subsequently validated in the validation cohort.Results: The DFS of proliferative HCC was significantly worse than nonproliferative HCC before and after PSM. Meanwhile, multivariate regression analysis revealed that liver cirrhosis (P = 0.032) and larger tumor size (P = 0.000) were independent risk factors of worse DFS. Lastly, the discriminative abilities of the predictive model for 1, 3, 5-year DFS rates, as determined by receiver operating characteristic (ROC) curves, were 0.702, 0.720, and 0.809 in the training cohort and 0.752, 0.776, and 0.851 in the validation cohort, respectively.Conclusion: This study developed a predictive model with satisfactory accuracy to predict the worse DFS in proliferative HCCs after liver resection. Moreover, this predictive model may serve as a valuable tool for clinicians to predict postoperative HCC recurrence, thereby enabling them to implement early preventative strategies.Keywords: hepatocellular carcinoma, proliferative, nonproliferative, predictive model, curative resection

Abstract Background Radical resection plus lymph node dissection is a common treatment for patients with T1-3N0M0 non-small cell lung cancer (NSCLC). Few models predicted the survival outcomes of these patients. This study aimed to developed a nomogram for predicting their overall survival (OS). Materials and methods This study involved 3002 patients with T1-3N0M0 NSCLC after curative resection between January 1999 and October 2013. 1525 Patients from Sun Yat-sen University Cancer Center were randomly allocated to training cohort and internal validation cohort in a ratio of 7:3. 1477 patients from ten institutions were recruited as external validation cohort. A nomogram was constructed based on the training cohort and validated by internal and external validation cohort to predict the OS of these patients. The accuracy and practicability were tested by Harrell's C-indexes, calibration plots and decision curve analyses (DCA). Results Age, sex, histological classification, pathological T stage, and HI standard were independent factors for OS and were included in our nomogram. The C-index of the nomogram for OS estimates were 0.671 (95% CI, 0.637–0.705),0.632 (95% CI, 0.581–0.683), and 0.645 (95% CI, 0.617–0.673) in the training cohorts, internal validation cohorts, and external validation cohort, respectively. The calibration plots and DCA for predictions of OS were in excellent agreement. An online version of the nomogram was built for convenient clinical practice. Conclusions Our nomogram can predict the OS of patients with T1-3N0M0 NSCLC after curative resection. The online version of our nomogram offer opportunities for fast personalized risk stratification and prognosis prediction in clinical practice.

To date, western data on colorectal ESD are limited. This study aimed to assess the efficacy and safety of rectal ESD for superficial lesions ≥ 8 cm. A total of 138 superficial rectal neoplasms treated by ESD were allocated in two groups: 25 in the "giant" ESD group and 113 in the control group. En bloc resection was achieved in 96% of cases in both groups. En bloc R0 resection rate was similar between the "giant" ESD group and the control group (84% vs 86%; p: 0.5) and curative resection was higher in the control group (81%) than in "giant" ESD group (68%) without reaching statistical significance (p: 0.2). Dissection time was significantly longer in the "giant" ESD group (251 vs 108 min; p <0.001), however, dissection speed was significantly higher (0.35 vs 0.17 cm2/min; p: 0.02).). Post-ESD stenosis was observed in 2 patients from the "giant" ESD group (8% vs 0% of control group, p: 0.03). No significant differences were found in delayed bleeding, perforation, local recurrences, and need for additional surgery. ESD for superficial rectal tumors ≥ 8 cm is a feasible, safe, and effective therapeutic option. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to investigate the prognostic significance of the preoperative controlling nutritional status (CONUT) score in patients with resectable advanced hypopharyngeal cancer. Methods: This retrospective study included 113 advanced hypopharyngeal cancer patients who underwent curative resection in our hospital from 2013 to 2017. The association between the CONUT score and clinicopathological variables was evaluated. The association between CONUT score and survival was analyzed using Kaplan–Meier survival curves and Cox regression. The efficacy of the CONUT score and other immune‐nutritional markers to predict prognosis was compared using a time‐dependent receiver operating characteristic (ROC). Results: Patients were divided into the high‐CONUT score group (≥3) and the low‐CONUT score group (≤2) according to ROC analysis. The CONUT score was associated with body mass index (p = 0.047), monocyte (p = 0.021), pharyngocutaneous fistula (p = 0.045), flap repairment (p = 0.034), tumor (T) classification (p = 0.034), node (N) classification (p = 0.036), subsite of tumor (p = 0.035), and negative pathologic factors (p < 0.001). Tumor, node, metastasis (TNM) stage, negative pathologic factors, adjuvant radiotherapy, postoperative chemoradiotherapy, and CONUT score were independent prognostic factors for survival. Patients with a higher CONUT score had worse overall survival (OS) (hazard ratio: 2.76, 95% confidence interval [CI]: 1.44–5.29, p = 0.002) and disease‐free survival (hazard ratio: 2.51, 95% CI: 1.28–4.91, p = 0.007). The area under the curve of the CONUT score (0.799) to predict 5‐year OS was greater than those of Preoperative Nutritional Index (0.769), platelet‐to‐lymphocyte ratio (0.643), neutrophil‐to‐lymphocyte ratio (0.565), and lymphocyte‐to‐monocyte ratio (0.577). Conclusion: The CONUT score is a prognostic marker for patients with resectable advanced hypopharyngeal cancer. Level of Evidence: 3 Laryngoscope, 133:2613–2620, 2023 [ABSTRACT FROM AUTHOR]

Background: Non-curative resection (non-CR) after endoscopic submucosal dissection (ESD) requires additional surgery due to the possibility of lymph node metastasis (LNM). Therefore, it is important to accurately predict the risk of non-CR to avoid unnecessary preoperative procedures. Thus, we aimed to develop and verify a nomogram to predict the risk of non-CR prior to ESD. Methods: Patients who underwent ESD for early gastric cancer (EGC) were divided into CR and non-CR groups based on the present ESD criteria. The pre-procedural factors, such as endoscopic features, radiologic findings, and pathology of the lesion, were compared between the groups to identify the risk factors associated with non-CR. A nomogram was developed using multivariate analysis, and its predictive value was assessed using an external validation group. Results: Among 824 patients, 682 were curative (82.7%) and 142 were non-curative (17.3%). By comparing two groups, endoscopic features including redness, whitish mucosal change, fold convergence, and large lesion size; histologic features such as moderately or poorly differentiated or signet ring cell carcinoma; and abnormal CT findings including non-specific lymph node enlargement and fold thickening were identified as significant predictors of non-CR. The nomogram was developed based on these predictors and showed good predictive performance in the external validation, with an area under the curve of 0.87. Conclusions: We developed a nomogram to predict the risk of non-CR prior to ESD. These predictive factors in addition to the existing ESD criteria can help provide the best treatment option for patients with EGC. [ABSTRACT FROM AUTHOR]

Abstract Background The role of adjuvant chemotherapy in esophageal squamous cell carcinoma (ESCC) remains controversial. This study aimed to evaluate the impact of adjuvant chemotherapy on survival in patients with positive nodes after surgery for ESCC. Methods We retrospectively reviewed the survival outcomes of node‐positive patients with ESCC who underwent curative resection with or without adjuvant chemotherapy between January 1994 and December 2015. Results We analyzed 460 patients (333 adjuvant chemotherapy, 127 surgery alone). The surgery‐alone group was older (64 vs. 60 years, p

Abstract Introduction Colorectal cancer with peritoneal metastasis (PM) has been considered a non‐curative disease. PM is associated with reduced overall survival (OS) and worse prognosis compared with metastasis at other sites. We aimed to investigate the treatment outcome and recurrence after curative resection of colorectal PM during a long‐term follow‐up. Methods Patients who were diagnosed with colorectal PM and underwent surgery between December 2001 and December 2019 were included (n = 309). Curative resection was defined as PM resection without residual disease after surgery (complete macroscopic resection). Results Of 309 patients, 208 (67.8%) had PM as an initially metastatic disease. Curative (R0/1) resection was achieved in 155 (50.2%) patients, while non‐curative operation (R2 resection or palliative operation including colostomy) was performed in 154 (49.8%) patients. Compared with patients who underwent non‐curative operation, those with curative resection more often had a single PM on preoperative imaging (34.2% vs. 20.8%, p = 0.011) and postoperative results (59.4% vs. 22.7%, p

Objective: This systematic review and meta-analysis aimed to investigate the role of neoadjuvant immunochemotherapy with or without radiotherapy [NIC(R)T] compared to traditional neoadjuvant therapies, without immunotherapy [NC(R)T]. Summary background data: NCRT followed by surgical resection is recommended for patients with early-stage esophageal cancer. However, it is uncertain whether adding immunotherapy to preoperative neoadjuvant therapy would improve patient outcomes when radical surgery is performed following neoadjuvant therapy. Methods: We searched PubMed, Web of Science, Embase, and Cochrane Central databases, as well as international conference abstracts. Outcomes included R0, pathological complete response (pCR), major pathological response (mPR), overall survival (OS) and disease-free survival (DFS) rates. Results: We included data from 5,034 patients from 86 studies published between 2019 and 2022. We found no significant differences between NICRT and NCRT in pCR or mPR rates. Both were better than NICT, with NCT showing the lowest response rate. Neoadjuvant immunotherapy has a significant advantage over traditional neoadjuvant therapy in terms of 1-year OS and DFS, with NICT having better outcomes than any of the other three treatments. There were no significant differences among the four neoadjuvant treatments in terms of R0 rates. Conclusions: Among the four neoadjuvant treatment modalities, NICRT and NCRT had the highest pCR and mPR rates. There were no significant differences in the R0 rates among the four treatments. Adding immunotherapy to neoadjuvant therapy improved 1-year OS and DFS, with NICT having the highest rates compared to the other three modalities. [ABSTRACT FROM AUTHOR]

Background: This study aimed to investigate the role of the alpha fetoprotein (AFP) ratio before and after curative resection in the prognosis of patients with hepatocellular carcinoma (HCC) and to develop a novel pre- to postoperative AFP ratio nomogram to predict recurrence free survival (RFS) for HCC patients after curative resection. Methods: A total of 485 pathologically confirmed HCC patients who underwent radical hepatectomy from January 2010 to December 2018 were retrospectively analyzed. The independent prognostic factors of hepatocellular carcinoma were identified by multivariate COX proportional model analysis, and the nomogram model was constructed. The receiver operating characteristic and the C-index were used to evaluate the accuracy and efficacy of the model prediction, the correction curve was used to assess the calibration of the prediction model, and decision curve analysis was used to evaluate the clinical application value of the nomogram model. Results: A total of 485 HCC patients were divided into the training cohort (n = 340) and the validation cohort (n = 145) by random sampling at a ratio of 7:3. Using X-tile software, it was found that the optimal cut-off value of the AFP ratio in the training cohort was 0.8. In both cohorts, the relapse-free survival of patients with an AFP ratio <0.8 (high-risk group) was significantly shorter than in those with an AFP ratio =0.8 (low-risk group) (P < 0.05). An AFP ratio <0.8 was an independent risk factor for recurrence of HCC after curative resection. Based on the AFP ratio, BCLC stage and cirrhosis diagnosis, a satisfactory nomogram was developed. The AUC of our nomogram for predicting 1-, 3-, and 5-year RFS was 0.719, 0.690, and 0.708 in the training cohort and 0.721, 0.682, and 0.681 in the validation cohort, respectively. Furthermore, our model demonstrated excellent stratification as well as clinical applicability. Conclusion: The AFP ratio was a reliable biomarker for tumor recurrence. This easy-to-use AFP ratio-based nomogram precisely predicted tumor recurrence in HCC patients after curative resection. [ABSTRACT FROM AUTHOR]

Abstract Background Prognosis for patients recurred rapidly after resection of pancreatic ductal adenocarcinoma (PDAC) was extremely poor. We proposed the concept of postoperative hyper-progression disease (PO-HPD) to define recurrence within 2 months after surgery, explored the role of surgery for postoperative HPD patients and determined the predictive preoperative risk factors and genomic features of PO-HPD. Methods 976 patients undergoing curative resection of PDAC were enrolled. Survival data of 1733 stage IV patients from the US Surveillance, Epidemiology and End Results database was also collected. Patients relapsed were grouped into 3 groups regarding of the recurrence time (within 2 months were PO-HPD, within 2 to 12 months were early recurrence (ER) and within > 12 months were late recurrence (LR)). Risk factors for PO-HPD were explored with logistic regression models. Genomic features of 113 patients were investigated using next-generation sequencing-based gene panel testing. Results 718 of 976 cases relapsed, 101were PO-HPD, 418 were ER and 199 were LR. Total survival of PO-HPD was 12.5 months, shorter than that of ER (16.7 months) and LR (35.1 months), and verged on that of stage IV patients (10.6 months). Preoperative risk factors for PO-HPD included red blood cell count

Background: The role of adjuvant chemotherapy in esophageal squamous cell carcinoma (ESCC) remains controversial. This study aimed to evaluate the impact of adjuvant chemotherapy on survival in patients with positive nodes after surgery for ESCC. Methods: We retrospectively reviewed the survival outcomes of node‐positive patients with ESCC who underwent curative resection with or without adjuvant chemotherapy between January 1994 and December 2015. Results: We analyzed 460 patients (333 adjuvant chemotherapy, 127 surgery alone). The surgery‐alone group was older (64 vs. 60 years, p < 0.001) and had more comorbidities (p = 0.004) than the adjuvant chemotherapy group. After propensity score matching, overall survival (OS) and recurrence‐free survival (RFS) of the adjuvant chemotherapy group were better than those of the surgery‐alone group: 5‐year OS rate 62.7% (95% confidence interval [CI] 54.4–72.3%) vs. 46.8% (95% CI 38.5–57%, p = 0.001) and 5‐year RFS rate 53.9% (95% CI 45.4–63.9%) vs. 36.2% (95% CI 28.3–46.3%, p < 0.001). Notably, in patients with pT3–4 stage, the adjuvant chemotherapy group had significantly better 5‐year OS rate (41.3% [95% CI 29.3–58.3%] vs. 18% [95% CI 10–32.5%], p = 0.01) and 5‐year RFS rate (37% [95% CI 25.3–53.9%] vs. 12% [95% CI 5.7–25.4%], p < 0.001) than in the surgery‐alone group. In multivariable analysis, adjuvant chemotherapy had a favorable effect on both OS (hazard ratio [HR] 0.562, 95% CI 0.426–0.741, p < 0.001) and RFS (HR 0.702, 95% CI 0.514–0.959; p = 0.026). Conclusion: Adjuvant chemotherapy may improve survival in node‐positive patients with ESCC, especially in those with pT3–4 stage. [ABSTRACT FROM AUTHOR]

Chronic obstructive pulmonary disease (COPD) serves as risk factor for the development of lung cancer and seems to have a prognostic impact after surgery for non-small cell lung cancer (NSCLC). The aim was to investigate the impact of COPD and postoperative mucostasis on the long-term survival after resected NSCLC. We retrospectively reviewed the data from 342 patients with curatively resected NSCLC. The prognostic long-term impact of COPD and postoperative mucostasis on overall survival (OS), recurrence free survival (RFS) and cancer specific survival (CSS) was calculated using univariable and multivariable Cox regression analyses. We found that 52.3% suffered from COPD and 25.4% had postoperative mucostasis. COPD was significantly more common among smokers (59.9%) compared with non-smokers (21.3%), (p < 0.001). There was a significant relationship between COPD and postoperative mucostasis (p = 0.006) and between smoking and mucostasis (p = 0.023). Patients with postoperative mucostasis had a significantly worse OS (p < 0.001), RFS (p = 0.009) and CSS (p = 0.008). The present analysis demonstrated that postoperative mucostasis, but not COPD, was associated with both worse short- and long-term outcomes for OS, RFS and CSS in curatively resected NSCLC.

Introduction: Colorectal cancer with peritoneal metastasis (PM) has been considered a non‐curative disease. PM is associated with reduced overall survival (OS) and worse prognosis compared with metastasis at other sites. We aimed to investigate the treatment outcome and recurrence after curative resection of colorectal PM during a long‐term follow‐up. Methods: Patients who were diagnosed with colorectal PM and underwent surgery between December 2001 and December 2019 were included (n = 309). Curative resection was defined as PM resection without residual disease after surgery (complete macroscopic resection). Results: Of 309 patients, 208 (67.8%) had PM as an initially metastatic disease. Curative (R0/1) resection was achieved in 155 (50.2%) patients, while non‐curative operation (R2 resection or palliative operation including colostomy) was performed in 154 (49.8%) patients. Compared with patients who underwent non‐curative operation, those with curative resection more often had a single PM on preoperative imaging (34.2% vs. 20.8%, p = 0.011) and postoperative results (59.4% vs. 22.7%, p < 0.001) and less often had concurrent metastasis (distant lymph node, liver, or lung) at the time of surgery (p < 0.001). During a median follow‐up of 90.4 months, 80.6% (125/155) patients had recurrence in the curative resection group; the peritoneum was the most common site (56.0%). The median OS was 47.7 months (95% CI, 39.2–56.2) in the curative resection group and 24.8 months (95% CI, 20.8–28.9) in the non‐curative resection group, respectively (p < 0.001). In particular, twenty‐six patients without recurrence showed long‐term survival after curative resection (median OS, 87.1 months; range, 40.1–127.5). Conclusion: Surgical resection can be considered for selected patients with colorectal PM because a significant number of them could seize the cure changes during their treatment continuum.

Background: The prognostic value of the tumor burden score (TBS) in patients with combined hepatocellular-cholangiocarcinoma (cHCC-CCA) remains unknown. This study aimed to investigate the impact of TBS on long-term outcomes after surgery. Methods: Patients who underwent radical-intent resection between June 2013 and December 2019 were retrospectively reviewed. Kaplan-Meier curves were used to analyze patient survival, and disease-free survival (DFS) and overall survival (OS) were examined in relation to TBS. Results: A total of 178 patients were included in this study, with 119 in the training cohort and 59 in the validation cohort. Kaplan-Meier curves showed that TBS was a strong prognostic indicator in patients with cHCC-CCA. Elevated TBS was associated with poorer DFS and OS (both P-value < 0.001) and was identified as an independent prognostic indicator. In addition, the prognostic value of TBS outperformed tumor size and number alone, microvascular invasion, and lymph node invasion. The prognostic significance of TBS was confirmed by the internal validation cohort. Conclusions: The present study suggested the significance of tumor morphology in assessing the prognosis of patients with cHCC-CCA who undergoing curative resection. The TBS is a promising prognostic index in patients with cHCC-CCA. Elevated TBS was related to a lower long-term survival rate and was identified as an independent risk factor for poor DFS and OS. Further research is needed to verify our results. [ABSTRACT FROM AUTHOR]

Objective: Primary appendiceal adenocarcinoma accounts for 1% of colorectal tumors and is a rare malignancy. Peritoneal dissemination commonly occurs as part of the natural course of disease, following the sequence of luminal wall invasion, obstruction, and perforation. Patients and Methods: Twenty patients with appendiceal adenocarcinoma were surgically treated in our hospital between 1990 and 2021. The clinicopathological features, preoperative diagnosis, intraoperative diagnosis, surgical techniques, postoperative adjuvant chemotherapy, chemotherapy, outcome, and prognostic factors for survival of patients with primary appendiceal adenocarcinoma were reviewed. Results: Patients (8 males, 12 females), with an age from 35 to 94 years (mean: 72.8 years), were involved in the study. Before surgery, 7 (35%) patients were diagnosed with primary appendiceal adenocarcinoma and 13 were diagnosed with other conditions. 10 patients had stage I or II disease and 10 patients had stage III or IV disease. Sixteen patients received curative resection, while 4 received non-curative resection. The cumulative five-year survival rate was 62.1%. The preoperative and intraoperative diagnoses, pathological stage, and curative resection had a significant impact on survival. Conclusions: The preoperative and intraoperative diagnoses, pathological stage, and curative resection had an important impact on survival of patients with primary appendiceal adenocarcinoma.

Background: The outcomes for patients with NASH-related HCC after curative resection have not been clarified. This study compared the overall survival (OS), time-to-tumor recurrence (TTR), and recurrence-free survival (RFS) associated with NASH-related HCC and virus-related HCC after resection. Methods: Patients with HCC who underwent curative resection were retrospectively enrolled. Baseline characteristics, including disease etiologies and clinical and tumor features, were reviewed. The primary outcomes were OS, TTR, and RFS. Results: Two hundred and six patients were enrolled (HBV: n = 121, HCV: n = 54, NASH: n = 31). Of those with virus-related HCC, 84.0% achieved viral suppression. In both the overall and propensity-score-matched cohorts, those with NASH-related HCC experienced recurrence significantly earlier than those with virus-related HCC (median TTR: 1108 days vs. non-reached; p = 0.03). Through multivariate analysis, NASH-related HCC (hazard ratio (HR), 2.27; 95% confidence interval (CI), 1.25–4.12) was independently associated with early recurrence. The unadjusted RFS rate of the NASH-related HCC group was lower than the virus-related HCC group. There was no difference in the OS between the two groups. Conclusions: NASH-related HCC was associated with earlier tumor recurrence following curative resection compared to virus-related HCC. Post-surgical surveillance is crucial for detecting early recurrence in patients with NASH-related HCC. [ABSTRACT FROM AUTHOR]

Purpose: Our study aims to examine the clinicopathological features, disease progression, management, and outcomes of gallbladder sarcomatoid carcinoma (GBSC) patients. Methods: Between January 2000 and December 2020, 50 gallbladder cancer (GBC)patientswhoreceivedsurgical treatment andwerepathologically verifiedas GBSC at our institution were enrolled. The clinical and pathological features and survival of these patients were retrospectively reviewed. Results: Themedianoverall survival (OS)ofGBSCpatientswas 14.5 months, andthe 1-, 2- and 3-yearOS rates were 68.0%, 32.0%, and 10.0%, respectively. Themedian progression-free survival (PFS)was 10.0months, and the 1-, 2-, and 3-year PFS rates were 42.0%, 16.0%, and 2.0%, respectively. Patients who received radical resection had obviously betterOS(18.0 vs. 7.0 months, P<0.001) and PFS (12.0 vs. 5.0 months, P<0.001) than those who underwent palliative resection. Multivariate analysis revealed that vascular invasion (P=0.033), curative operation (P<0.001) and postoperative chemotherapy (P=0.033) were independent risk factors for PFS. We further identified postoperative chemotherapy (P=0.010) and curative operation (P<0.001) as independent prognostic factors affectingtheOSofGBSCpatients. After curative surgery, patients who underwent S-1-based chemotherapy showed significantly longer recurrence-free survival (RFS) than those who underwent other chemotherapy regimens (20.0 vs 11.0 months, P=0.028). Conclusion: GBSC patients always have aggressive biological behaviors and remarkably poor prognoses. Most GBSC patients are diagnosed in advanced stages, and timely radical operation together with postoperative chemotherapy is important. S-1-based chemotherapy may be a selectively efficient regimen to prolong the survival of GBSC patients. [ABSTRACT FROM AUTHOR]

Introduction: There is no consensus on the optimal surveillance interval for patients undergoing resection of colorectal liver metastases (CRLM). We sought to assess the timing and intensity of recurrence following curative-intent resection of CRLM utilizing a recurrence-free survival (RFS) hazard function analysis., Methods: Patients with CRLM who underwent curative-intent resection were identified from a multi-institutional database. The RFS hazard function was used to plot hazard rates and identify the peak of recurrence over time., Results: Among 1804 patients, the median RFS was 19.9 months. In the analytic cohort, the RFS hazard curve peaked at 5.9 months (peak hazard rate: 0.054) and gradually declined, indicative of early recurrence. In subgroup analyses, patients with high and medium tumor burden scores (TBS) had RFS hazard peaks at 4.9 months (peak hazard rate: 0.060) and 5.8 months (peak hazard rate: 0.054), respectively. In contrast, patients with low TBS had a later peak at 7.5 months, with the lowest peak hazard rate of 0.047., Conclusions: The recurrence peak for CRLM patients occurred approximately 6 months postsurgery, highlighting the need for intensified early postoperative surveillance. Patients with high TBS experienced earlier recurrence, underscoring the importance of close monitoring, particularly during the first 6 months after surgery., (© 2024 The Author(s).

Background and Aims: We aimed to evaluate the feasibility, safety and efficacy of endoscopic submucosal dissection for recurrent rectal neoplastic lesions after transanal microsurgery of superficial rectal neoplasms., Methods: Multicenter retrospective study., Main Outcomes: recurrence at first endoscopic follow-up, En bloc, R0 and curative resections., Results: 39 patients were included. 71 % percent of lesions were located in the lower rectum, 57 % reached the pectineal line. 67 % were laterally spreading tumor granular type, 33 % were protruding lesions. Median size was 41 mm (IQR 30 - 60). Median operation time was 70 min (IQR 35 - 97). 92 % were successfully resected en bloc. R0 and curative resection rates were 77 % and 71 %, respectively. Perirectal fat was visualized in 10 patients, none of them required surgery. One significant hematochezia (3 %), two stenosis (6 %) and one untreatable anal incontinence (3 %) occurred. Median hospital stay after endoscopic submucosal dissection was 2 days (IQR 1-2). Median period for the first endoscopy follow-up was 6 months (IQR 4-8). A single post endoscopic submucosal dissection recurrence adenoma was found during follow-up (3 %), occurring after a non-en bloc resection., Conclusion: Endoscopic submucosal dissection is a good option for safely achieving high rates of complete en bloc resection in cases of recurrent superficial rectal tumor after transanal microsurgery., Competing Interests: Conflict of interest - Ali Jaafar has no conflict of interest. - Xavier Dray is co-founder and shareholder of Augmented Endoscopy.

Background: Early recurrence is the leading cause of death for patients with perihilar cholangiocarcinoma (pCCA) after surgery. Identifying high-risk patients preoperatively is important. This study aimed to construct a preoperative prediction model for the early recurrence of patients with pCCA to facilitate planned treatment with curative resection., Methods: This study ultimately enrolled 400 patients with pCCA after curative resection in 5 hospitals between 2013 and 2019. They were randomly divided into training (n = 300) and testing groups (n = 100) at a ratio of 3:1. Associated variables were identified via least absolute shrinkage and selection operator (LASSO) regression. Four machine learning models were constructed: support vector machine, random forest (RF), logistic regression, and K-nearest neighbors. The predictive ability of the models was evaluated via receiving operating characteristic (ROC) curves, precision-recall curve (PRC) curves, and decision curve analysis. Kaplan-Meier (K-M) survival curves were drawn for the high-/low-risk population., Results: Five factors: carbohydrate antigen 19-9, tumor size, total bilirubin, hepatic artery invasion, and portal vein invasion, were selected by LASSO regression. In both the training and testing groups, the ROC curve (area under the curve: 0.983 vs 0.952) and the PRC (0.981 vs 0.939) showed that RF was the best. The cutoff value for distinguishing high- and low-risk patients was 0.51. K-M survival curves revealed that in both groups, there was a significant difference in RFS between high- and low-risk patients (P < .001)., Conclusion: This study used preoperative variables from a large, multicenter database to construct a machine learning model that could effectively predict the early recurrence of pCCA in patients to facilitate planned treatment with curative resection and help clinicians make better treatment decisions., (Copyright © 2024 The Authors.

Background/aim: Granzyme B (GZMB) is mainly produced by natural killer (NK) cells and activated CD8-positive T cells to induce tumor cell apoptosis. We analyzed the significance of GZMB expression in gastric cancer (GC) tissues from patients with pathological (p)Stage II/III GC after curative resection., Patients and Methods: Patients with pStage II/III GC who received curative resection (n=253) were included and the expression levels of GZMB in GC tissues and in the adjacent normal mucosa were measured using quantitative real-time polymerase chain reaction. The expression levels in GC tissues and clinicopathological features and overall survival (OS) were compared in these patients., Results: GZMB expression levels were significantly higher in GC tissues than in the adjacent normal mucosa. GZMB expression levels in GC tissues were not associated with any clinicopathological features. The 5-year OS rate in the high-GZMB expression group was significantly better than that in the low-expression group (5-year survival rate 72.0% vs. 55.7%; p=0.009). Furthermore, on multivariate analysis, high-GZMB expression was an independent factor for better OS (hazard ratio=0.652; 95% confidence interval=0.432-0.987; p=0.043)., Conclusion: In patients with locally advanced GC after curative resection, GZMB expression in GC tissue may be a useful prognostic marker., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J.

Background: The Naples prognostic score (NPS) determined by the nutritional and inflammatory condition of an individual is attracting growing attention for predicting postoperative outcomes in a variety of malignancies. The study aimed to assess the clinical significance of a modified NPS (M-NPS) and establish and validate nomograms incorporating M-NPS in curative stage II-III colon cancer patients., Methods: We retrospectively analyzed 328 stage II-III colon cancer patients receiving radical surgical resection at our hospital from January 2011 to December 2016. Kaplan-Meier (KM) survival analysis and Cox regression analysis were executed for overall survival (OS) and cancer-specific survival (CSS). Independent predictive indicators were applied to develop nomograms. The model's performance was evaluated using many different methods., Results: Of a total of 328 cases, 153 cases were in group 0, 145 in group 1, and 30 in group 2. In terms of OS or CSS, there were obvious differences between groups 0 and 1, and between groups 0 and 2. Age, obstruction, N stage, gross tumor type, and M-NPS group were independent prognostic indicators for OS, while obstruction, gross tumor type, M-NPS group, and N stage were independent predictive parameters for CSS. Furthermore, the training and validation sets were randomly allocated among a cohort of 328 patients. OS and CSS prediction nomograms were developed. In the training and validation cohort, the C-index and ROC analysis showed good discrimination, calibration curves exhibited an excellent level of consistency between model-predicted survival and actual survival outcomes, and DCA curves demonstrated good clinical performance., Conclusion: M-NPS is a reliable survival predictor in patients with curative stage II-III colon cancer. Nomograms incorporating M-NPS for OS and CSS have good predictive performance and clinical utility., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Li, Cheng, Huo, Zhao, Yuan, Chen, Yu, Mu and Sun.)

Background: Postoperative recurrence impedes the curability of early-stage hepatocellular carcinoma (E-HCC). We aimed to establish a novel recurrencerelated pathological prognosticator with artificial intelligence, and investigate the relationship between pathological features and the local immunological microenvironment. Methods: A total of 576 whole-slide images (WSIs) were collected from 547 patients with E-HCC in the Zhongshan cohort, which was randomly divided into a training cohort and a validation cohort. The external validation cohort comprised 147 Tumor Node Metastasis (TNM) stage I patients from The Cancer Genome Atlas (TCGA) database. Six types of HCC tissues were identified by a weakly supervised convolutional neural network. A recurrence-related histological score (HS) was constructed and validated. The correlation between immune microenvironment and HS was evaluated through extensive immunohistochemical data. Results: The overall classification accuracy of HCC tissues was 94.17%. The Cindexes of HS in the training, validation and TCGA cohorts were 0.804, 0.739 and 0.708, respectively. Multivariate analysis showed that the HS (HR= 4.05, 95% CI: 3.40-4.84) was an independent predictor for recurrence-free survival. Patients in HS high-risk group had elevated preoperative alpha-fetoprotein levels, poorer tumor differentiation and a higher proportion of microvascular invasion. The immunohistochemistry data linked the HS to local immune cell infiltration. HS was positively correlated with the expression level of peritumoral CD14+ cells (p= 0.013), and negatively with the intratumoral CD8+ cells (p< 0.001). Conclusions: The study established a novel histological score that predicted short-term and long-term recurrence for E-HCCs using deep learning, which could facilitate clinical decision making in recurrence prediction and management.

Background: Prognosis for patients recurred rapidly after resection of pancreatic ductal adenocarcinoma (PDAC) was extremely poor. We proposed the concept of postoperative hyper-progression disease (PO-HPD) to define recurrence within 2 months after surgery, explored the role of surgery for postoperative HPD patients and determined the predictive preoperative risk factors and genomic features of PO-HPD.Methods: 976 patients undergoing curative resection of PDAC were enrolled. Survival data of 1733 stage IV patients from the US Surveillance, Epidemiology and End Results database was also collected. Patients relapsed were grouped into 3 groups regarding of the recurrence time (within 2 months were PO-HPD, within 2 to 12 months were early recurrence (ER) and within > 12 months were late recurrence (LR)). Risk factors for PO-HPD were explored with logistic regression models. Genomic features of 113 patients were investigated using next-generation sequencing-based gene panel testing.Results: 718 of 976 cases relapsed, 101were PO-HPD, 418 were ER and 199 were LR. Total survival of PO-HPD was 12.5 months, shorter than that of ER (16.7 months) and LR (35.1 months), and verged on that of stage IV patients (10.6 months). Preoperative risk factors for PO-HPD included red blood cell count < 3.94*10^12/L, CA19-9 ≥ 288.6 U/mL, CA125 ≥ 22.3 U/mL and tumor size≥3.45 cm. Mutations of CEBPA, ATR and JAK1 were only identified in PO-HPD and they owned lower level of CN gain compared to others.Conclusions: Prognosis of PO-HPD was extremely poor and the role of surgery for PO-HPD should be prudently assessed.

Purpose: Tumor budding is a histological characteristic defined as the presence of small clusters of cancer cells at the invasion front. Its significance in duodenal adenocarcinoma (DA) has not been fully described. Methods: A single-center, retrospective study was conducted. Patients who underwent curative surgery for histologically diagnosed DA from January 2006 to December 2018 at Kansai Medical University Hospital were included. Tumor budding was counted per 0.785 mm2 and classified as low (0–4 buds), intermediate (5–9 buds), or high (≥ 10 buds). Results: In total, 47 patients were included. The 5-year overall survival and relapse-free survival rates were 77% and 72%, respectively. High tumor budding was seen in 15 patients (32%). Excluding patients with superficial type (pT1) DA (n = 22), high tumor budding [hazard ratio (HR) 13.4, p = 0.028], regional lymph node metastasis (HR 19.9, p = 0.039), and adjuvant chemotherapy (HR 0.056, p = 0.036) were independent factors related to the overall survival in multivariate analyses. Distant metastases occurred significantly more often in patients who had high tumor budding than in others (p = 0.039). Conclusion: The data suggest that high tumor budding is a predictor of a poor prognosis in resected DA. [ABSTRACT FROM AUTHOR]

Background: Entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are recommended as first-line choices regarding the treatment of chronic hepatits B. The impact of the two antiviral agents on prognosis of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC) after curative liver resection remains to be explored. We aimed to assess the effect of antiviral therapy with ETV or TDF after curative resection on the prognosis of patients with HBV-related HCC.Methods: A total of 1173 consecutive patients who were treated with ETV or TDF after curative liver resection for HCC were enrolled in the study. HCC recurrence, overall survival, postoperative liver function reserve, and early virologic (VR) and biochemical responses (BR) of patients were compared between the ETV and TDF groups by propensity score matching (PSM) from the date of liver resection for HCC.Results: No difference was observed with recurrence-free survival between TDF and ETV in the PSM cohort (hazard ratio [HR], 0.91; 95% confidence interval [CI] 0.70-1.17; P = 0.45). No difference was observed with early VR and BR between TDF and ETV in the PSM cohort. Compared with ETV, TDF therapy was associated with significantly better protection of liver function and higher overall survival rates in the PSM cohort (HR, 0.37; 95% CI 0.20-0.71; P = 0.002). After PSM, 69 (40.8%) patients in the ETV group and 63 (57.3%) patients in the TDF group had single tumor recurrence, while the TDF group had significantly more patients with single tumor recurrence in the PSM cohort (P = 0.007).Conclusions: For patients who underwent curative resection for HBV-related HCC, TDF treatment had a significantly better overall survival and better protection of liver function, but no difference in the incidences of HCC recurrence than ETV treatment.

Background: The curative criteria after endoscopic submucosal dissection for early gastric carcinoma were updated by the Japanese Gastric Cancer Association. No study has shown promising results with endoscopic submucosal dissection for early adenocarcinoma of esophagogastric junction based on the new curative criteria. The purpose of this study was to validate clinical efficacy of the application of the curative criteria of the 5th edition Japanese gastric cancer treatment guidelines for early adenocarcinoma of esophagogastric junction after endoscopic submucosal dissection. Methods: Patients who underwent endoscopic submucosal dissection for Siewert type II adenocarcinoma between January 2013 and June 2018 were eligible for this study. Clinical and pathological features and treatment outcomes were retrospectively reviewed using medical records. Results: The success rate for en-bloc resection was 97.2% (172/177) and the curative resection rate was 71.2% (126/177). Additional endoscopic submucosal dissection or radical surgery was conducted in 10 patients (5.6%) who did not fulfil the curative resection criteria, while one patient with curative resection remedied with endoscopic submucosal dissection because of recurrence. According to eCura scoring system, 94 patients (53.1%) were categorized into eCura A, 34 patients (19.2%) into eCura B, 11 patients (6.2%) into eCura C-1, and 38 patients (21.5%) into eCura C-2. Five patients categorized as eCura C-2 underwent radical surgery, two of whom have lymph node metastasis. Conclusions: Endoscopic submucosal dissection for early adenocarcinoma of esophagogastric junction that met the expanded criteria of the 5th edition Japanese gastric cancer treatment guidelines were acceptable and should be the standard treatment instead of surgical resection.

Background: Endoscopic submucosal dissection (ESD) is an effective treatment for early gastric cancer (EGC); however, its curative resection rate is low for undifferentiated-type EGC. We developed and externally validated a prediction model for curative ESD of undifferentiated-type EGC. Methods: In this cross-sectional study, we included 448 patients who underwent ESD for undifferentiated-type EGC at 18 hospitals in Korea between 2005 and 2015 in the development cohort and 1342 patients who underwent surgery at two hospitals in the validation cohort. A prediction model was developed using the logistic regression model. Results: Endoscopic tumor size 1–2 cm (odds ratio [OR], 2.40; 95% confidence interval [CI] 1.54–3.73), tumor size > 2 cm (OR, 14.00; 95% CI 6.81–28.77), and proximal tumor location from the lower to upper third of the stomach (OR, 1.45; 95% CI 1.03–2.04) were independent predictors of non-curative ESD. A six-score prediction model was developed by assigning points to endoscopic tumor size > 2 cm (five points), tumor size 1–2 cm (two points), upper third location (two points), and middle third location (one point). The rate of curative ESD ranged from 70.6% (score 0) to 11.6% (score 5) with an area under the receiver operating characteristic curve (AUC) of 0.720 (95% CI 0.673–0.766). The model also showed good performance in the validation cohort (AUC, 0.775; 95% CI 0.748–0.803). Conclusions: This six-score prediction model may help in predicting curative ESD and making informed decisions about the treatment selection between ESD and surgery for undifferentiated-type EGC.

Résumé: La résection endoscopique monobloc est le traitement de référence des cancers superficiels colorectaux car elle permet une efficacité carcinologique comparable à la chirurgie avec une plus faible morbi-mortalité. Cette résection est dite curative lorsque le risque d'envahissement ganglionnaire est négligeable, c'est-à-dire lorsqu'un certain nombre de critères histopronostiques sont remplis (marges latérales et profondes saines, absence d'emboles lympho-vasculaires ou de bourgeonnement tumoral, bon degré de différenciation et profondeur d'invasion sous-muqueuse < 1 000 μm). L'absence d'un seul de ces critères doit théoriquement conduire à la réalisation d'une chirurgie complémentaire avec curage ganglionnaire. Le problème actuel est que le « poids » de chacun de ses critères histopronostiques n'est probablement pas équivalent sur le risque d'envahissement ganglionnaire et leur perfectionnement permettrait d'améliorer certaines prises de décisions lors de nos réunions de concertation pluridisciplinaire. Dans cet article, nous aborderons le « poids ganglionnaire » de chacun de ces critères ainsi que les perspectives d'amélioration de nos critères histo-pronostiques. Enbloc endoscopic resection is the standard treatment for superficial colorectal cancers because it provides oncological efficacy comparable to surgery with lower morbidity and mortality. This resection is said to be curative when the risk of lymph node invasion is negligible, that is to say when a certain number of histopronostic criteria are met (free lateral and deep margins, absence of lympho-vascular emboli or tumor budding, good/moderate degree of differentiation and depth of submucosal invasion <1 000 μm). The absence of only one of these criteria should theoretically lead to additional surgery with lymph node dissection. The current problem is that the "weight" of each of its histo-prognostic criteria is probably not equivalent on the risk of lymph node invasion and their improvement could help improve certain decision-making during our multidisciplinary meetings. In this article, we will discuss the "lymph node weight" of each of these criteria as well as the prospects for improving our histo-prognostic criteria. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is available in the text Objective: The aim of this study was to analyze esophageal cancer patients who previously underwent neoadjuvant therapy followed by a curative resection to determine whether additional adjuvant therapy is associated with improved survival outcomes. Summary Background Data: Neoadjuvant therapy followed by surgery is the standard of care for locally advanced esophageal cancer, whereas adjuvant therapy is typically employed for patients with residual disease. However, the role of adjuvant therapy after a curative resection is still uncertain. Methods: MEDLINE, EMBASE, and CENTRAL databases were searched for studies comparing patients with esophageal cancer who underwent neoadjuvant therapy and curative resection with and without adjuvant therapy. Primary outcome was overall survival (OS), and random effects meta-analysis was conducted where appropriate. Grading of recommendations, assessment, development, and evaluation was used to assess the certainty of evidence. Results: Ten studies involving 6462 patients were included. When compared to patients who received neoadjuvant therapy and esophagectomy alone, adjuvant therapy groups experienced a significant decrease in mortality by 48% at 1 year (Risk Ratio (RR) 0.52, 95% confidence interval [CI] 0.41–0.65, P < 0.001, moderate certainty). This reduction in mortality was carried through to 5-year follow-up (RR 0.91, 95% CI 0.86–0.96, P < 0.001, moderate certainty). The difference between the adjuvant therapy and the control group was uncertain regarding the secondary outcomes. Conclusion: Adjuvant therapy after neoadjuvant treatment and esophagectomy with negative resection margins provide an improved OS at 1 and 5 years with moderate to high certainty of evidence, but the benefit for disease-free survival and locoregional/distal recurrence remain uncertain due to limited reporting of these outcomes.

Purpose: Distant recurrence is a devastating occurrence after colorectal cancer resection. This study aimed to identify the risk factors for distant recurrence following surgery. Methods: All consecutive colorectal cancer resections with curative intent were included from a prospectively maintained colorectal cancer database. The primary outcome was to identify predictive factors for distant recurrence of colorectal cancer. Results: A total of 670 eligible cases were identified with 88 (13.1%) developing distant recurrence during the follow-up period. The median time to distant recurrence was 1.2 years with the most common sites of distant recurrence being the lung (44.3%) and liver (44.3%). Predictive factors for distant recurrence in colon cancer included a high tumor, nodal, and overall stage of the primary cancer (p < 0.001 for all). Surgical complications (p = 0.007), including anastomotic leak (p = 0.023), were associated with a higher risk of developing distant recurrence in rectal cancer patients. Independent variables associated with distant recurrence included tumor stage (OR 1.61, p = 0.011), nodal stage (OR 2.18, p < 0.001), and both KRAS (OR 11.04, p < 0.001) and MLH/PMS2 (OR 0.20, p = 0.035) genetic mutations. Among patients with distant recurrence, treatment with surgery conferred the best survival, with patients < 50 years of age having the best overall 5-year survival. Conclusion: Predictive factors for distant recurrence include advanced tumor and nodal stages, and the presence of KRAS and MLH/PSM2 mutations. Clinicians should be cognizant of these risk factors, and instate close surveillance plans for patients exhibiting these features. [ABSTRACT FROM AUTHOR]

Abstract Background We aimed to develop a clinical applicable nomogram to predict overall survival (OS) for patients with curatively resected nonmetastatic colorectal cancer. Methods Records from a retrospective cohort of 846 patients with complete information were used to construct the nomogram. The nomogram was validated in a prospective cohort of 379 patients. The performance of the nomogram was evaluated with concordance index (c‐index), time‐dependent receiver operating characteristic (ROC) curves, calibration plots, and decision curve analyses for discrimination, accuracy, calibration ability, and clinical net benefits respectively, and further compared with AJCC 8th TNM staging and the MSKCC nomogram. Risk stratification based on nomogram scores was performed with recursive partitioning analysis. Results The nomogram incorporated age, Glasgow prognostic score, pretreatment carcinoembryonic antigen levels, T staging, N staging, number of harvested lymph nodes, and histological grade. Compared with the 8th AJCC staging and MSKCC model, the nomogram had a statistically higher c‐index (0.77, 95% CI: 0.73‐0.80), bigger areas under the time‐dependent ROC curves (AUC at 3 years: 79; at 5 years: 79), and improved clinical net benefits. Calibration plots revealed no deviations from reference lines. All results were reproducible in the validation cohort. Nomogram‐based risk stratification successfully discriminated patients within each AJCC stage (all log‐rank P

Abstract Background In the past four decades, the incidence of cholangiocarcinoma, especially intrahepatic cholangiocarcinoma (ICC), has raised rapidly worldwide. Completeness of resection, max size of tumor and etc. are widely recognized as prognostic factors. However, the prognosis significance of perineural invasion (PNI) on recurrence-free survival (RFS) and overall survival (OS) in ICC patients is controversial. Methods ICC patients who underwent curative hepatectomy and diagnosed pathologically were retrospectively analyzed. Patients were grouped by existence of PNI and outcomes were compared between groups. The potential relationship between PNI and postoperative chemotherapy was also investigated. Results There was no significant difference in demographic, clinical staging or tumor index between two groups, except positive hepatitis B surface antigen and CA19–9. PNI negative group showed a better prognosis in RFS (P
