Abstract Aim: The purpose of this study was to compare clinicopathological features of patients with non-schistosomal and schistosomal colorectal cancer to explore the effect of schistosomasis on CRC patients` clinical outcomes. Methods: 351 cases of CRC were retrospectively analyzed in this study. Survival curves were constructed by using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard regression models were performed to identify associations with outcome variables.Results: Patients with schistosomiasis (CRC-S) were significantly older (Table 3, P＜0.001) than patients without schistosomiasis (CRC-NS). However, there were no significant differences between CRC-S and CRC-NS patients in other clinicopathological features. Schistosomiasis were associated with adverse overall survival upon K-M analysis (P=0.0277). By univariate and multivariate analysis, as shown in Table 2, gender (P=0.003), TNM stage (P＜0.001), schistosomiasis (P=0.025), lymphovascular invasion (P=0.030) and cancer node (P＜0.001) were all independent predictors in the whole cohort. When patients were stratified according to clinical stage and lymph node metastasis state. Schistosomiasis was also an independent predictors in patients with stage Ⅲ-Ⅳ tumors and in patients with lymph node metastasis, but not in patients with stage Ⅰ-Ⅱ tumors and in patients without lymph node metastasis.Conclusion: Schistosomiasis was significantly correlated with OS and it was an independent prognostic factor for OS in the whole cohort. When patients were stratified according to clinical stage and lymph node metastasis state, schistosomiasis was still an independent unfavorably prognosis factor for OS in patients with stage Ⅲ-Ⅳ tumors or patients with lymph node metastasis.

Methods: 351 cases of CRC were retrospectively analyzed in this study. Survival curves were constructed by using the Kaplan-Meier (K-M) method. Univariate and multivariate Cox proportional hazard regression models were performed to identify associations with outcome variables.Results: Colorectal cancer patients with schistosomiasis (CRC-S) were significantly older (P＜0.001) than the patients without schistosomiasis (CRC-NS). However, there were no significant differences between CRC-S and CRC-NS patients in other clinicopathological features. Schistosomiasis were associated with adverse overall survival (OS) upon K-M analysis (P=0.0277). By univariate and multivariate analysis, gender (P=0.003), TNM stage (P＜0.001), schistosomiasis (P=0.025), lymphovascular invasion (P=0.030) and lymph nodes positive for CRC (P＜0.001) were all independent predictors in the whole cohort.

Abstract Aim The purpose of this study was to compare clinicopathological features of patients with non-schistosomal and schistosomal colorectal cancer to explore the prognostic role of schistosoma infection in colorectal cancer(CRC). Methods 354 cases of CRC were retrospectively analyzed in a tissue microarray format. Survival curves were constructed by using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard regression models were performed to identify associations with outcome variables. Results Patients with schistosomiasis (CRC-S) were significantly older ( P <0.001) and were mostly in stage III and IV tumors ( P <0.001) than patients without schistosomiasis (CRC-NS). However, there were no significant difference between CRC-S and CRC-NS patients in other clinicopathological features. Overall, CRC-S patients were associated with adverse overall survival upon K-M analysis ( P =0.0239). By univariate and multivariate analysis, CRC-S patients were significantly correlated with OS ( P =0.041), but it was not an independent prognostic factor. In addition, age( P =0.013), gender ( P =0.008), tumor differentiation ( P =0.018) and invasive depth ( P =0.013) were all independent predictors. When patients were stratified according to clinical stage and lymph node metastasis state, the prognostic role was not consistent. In patients with stage III-IV tumors and with lymph node metastasis, schistosomiasis, gender and invasive depth were independent predictors, but not in patients with stage I-II tumors and in patients without lymph node metastasis. Conclusion Schistosomiasis is an unfavorable factor for OS and could be considered to refine risk stratification and provide better risk-oriented treatment for CRC patients with different clinical stage or lymph node metastasis state.

Abstract Background Patients with Pancreatic cancer (PC) have worse survival than patients with any other gastrointestinal malignancy. In present study, it is aim to investigate the prognostic factors of pancreatic carcinoma after curative resection . Methods 72 cases suffered from pancreatic carcinoma or periampullary carcinoma received curative, nine clinicopathologic factors that could possibly influence survival for postoperative mortality and overall survival were selected for univariate analysis and multivariate analysis using Cox proportional hazard mode. Results Univariate analysis showed that major factors of influence survival were size of the tumor, lymph node metastasis, and grade of differentiation (P<0.05). Multivariate analysis showed that lymph node metastasis and size of the tumor were the most important prognostic factors by multivariate analysis using the Cox proportional hazard model (P<0.01). Conclusions Prognostic factors of pancreatic carcinoma after resection are closed related to lymph node metastasis and the size of the tumor.

Abstract Purpose Although some studies have reported differences in clinicopathological features between left- and right-sided advanced colorectal cancer (CRC), there are few reports regarding early-stage disease. In this study, we aimed to compare the clinicopathological features of left- and right-sided T1 CRC. Methods Subjects were 1142 cases with T1 CRC undergoing surgical or endoscopic resection between 2001 and 2018 at Showa University Northern Yokohama Hospital. Of these, 776 cases were left-sided (descending colon to rectum) and 366 cases were right-sided (cecum to transverse colon). We compared clinical (patients age, sex, tumor size, morphology, initial treatment) and pathological features (invasion depth, histological grade, lymphatic invasion, vascular invasion, tumor budding) including lymph node metastasis (LNM). Results Left-sided T1 CRC showed significantly higher rates of LNM (left-sided 12.0% vs. right-sided 5.4%, P < 0.05) and lymphatic invasion (left-sided 32.7% vs. right-sided 23.2%, P < 0.05). Especially, the sigmoid colon and rectum showed higher rates of LNM (12.4% and 12.1%, respectively) than other locations. Patients with left-sided T1 CRC were younger than those with right-sided T1 CRC (64.9 years ±11.5 years vs. 68.7 ± 11.6 years, P < 0.05), as well as significantly lower rates of poorly differentiated carcinoma/mucinous carcinoma than right-sided T1 CRC (11.6% vs. 16.1%, P < 0.05). Conclusion Left-sided T1 CRC, especially in the sigmoid colon and rectum, exhibited higher rates of LNM than right-sided T1 CRC, followed by higher rates of lymphatic invasion. These results suggest that tumor location should be considered in decisions regarding additional surgery after endoscopic resection. Trial registration This study was registered with the University Hospital Medical Network Clinical Trials Registry (UMIN 000032733).

PurposeThis study aimed to evaluate the ratio of metastatic and removed lymph nodes (RPL) and the number of metastatic lymph nodes (MLNs) in predicting postoperative survival for International Federation of Gynecology and Obstetrics stage IA2 to IIA cervical cancer after radical hysterectomy and pelvic lymphadenectomy (RHPL).MethodsA retrospective study was conducted in which 120 patients with lymph node metastasis who underwent RHPL for cervical cancer from 2000 to 2006 was analyzed to identify the prognostic indicators by using Kaplan-Meier and Cox proportional hazard methods.ResultsOf 588 patients with cervical cancer who underwent RHPL, the 5-year survival rate (YSR) of 120 with lymph node metastasis was much lower than that of 468 without lymph node metastasis (22.4% vs 84.4%, P < 0.001). By cut-point survival analysis, RPL cutoff was designed as 10%, with the 5-YSR of 42.9% and 11.8%, and MLN count cutoffs were designed as 1 and 5, with the 5-YSR of 62.5%, 20.8%, and 7.8%, respectively. With univariate analysis, increasing RPL and MLN counts were associated with a poorer survival in women with node metastasis cervical cancers. Stage, histologic grade, RPL, and MLN count were significant independent prognostic factors for survival in a multivariate Cox proportional hazard model. In addition, RPL was verified superior to MLN count in prognostic evaluation for patients with IA2 to IIA cervical cancer after RHPL because the hazard ratio of RPL (3.195) was higher than that of MLN count (1.578).ConclusionsThe RPL and MLN count may be used as the independent prognostic parameters in patients with cervical cancer with lymph node metastasis after RHPL. Comparison of the superiority of RPL and MLN count for better predicting the survival of patients with cervical cancer deserves to be investigated further.

This study aimed at building a prognostic signature based on a candidate gene panel whose expression may be associated with lymph node metastasis (LNM), thus potentially able to predict colorectal cancer (CRC) progression and patient survival. The mRNA expression levels of 20 candidate genes were evaluated by RT-qPCR in cancer and normal mucosa formalin-fixed paraffin-embedded (FFPE) tissues of CRC patients. Receiver operating characteristic curves were used to evaluate the prognosis performance of our model by calculating the area under the curve (AUC) values corresponding to stage and metastasis. A total of 100 FFPE primary tumor tissues from stage I–IV CRC patients were collected and analyzed. Among the 20 candidate genes we studied, only the expression levels of VANGL1 significantly varied between patients with and without LNMs (p = 0.02). Additionally, the AUC value of the 20-gene panel was found to have the highest predictive performance (i.e., AUC = 79.84%) for LNMs compared with that of two subpanels including 5 and 10 genes. According to our results, VANGL1 gene expression levels are able to estimate LNMs in different stages of CRC. After a proper validation in a wider case series, the evaluation of VANGL1 gene expression and that of the 20-gene panel signature could help in the future in the prediction of CRC progression.

Background. Gastric cancer (GC) is an important malignant disease around the world. Abnormalities of microRNAs (miRNAs) have been implicated in carcinogenesis of various cancers. In the present study, we examined miR-21 expression in human gastric cancer with lymph node metastasis and attempted to uncover its relationship with clinicopathologic data, especially with lymph node metastasis.Materials and Methods. The expression levels of miR-21 in the tumor specimens of GC patients were quantified by RT-PCR. The correlation between miR-21 level and multiple clinicopathological factors was then examined by Mann-Whitney test, Kaplan-Meier survival analysis, and operating characteristic (ROC) analysis.Results. The expression level of miR-21 was higher in GC patients with lymph node metastasis than in those without lymph node metastasis (P<0.05). Expression level of miR-21 was significantly correlated with histologic type, T stage, lymph node metastasis and pTNM stage. The overall survival rates in GC patients with low upregulated miR-21 expression were significantly higher than those with high upregulated miR-21 (P<0.05).Conclusion. A close association is implicated between the elevated miR-21and lymph node metastasis, which could potentially be exploited as a practical biomarker for lymph node metastasis in patients with GC.
