Background: A systematic analysis was conducted to clarify the relationship between miR-143/145 and the prognosis of colorectal cancer. Materials and methods: We searched four databases: PubMed, EMBASE, Web of Science, and the Cochrane Library. We extracted and estimated the hazard ratios for survival outcomes, which compared low and high expression levels of miR-143/145 in colorectal cancer patients in the available studies. Each individual hazard ratio was used to calculate the pooled hazard ratio. Results: A total of 17 articles including 5128 patients were ultimately included. The results showed that there was no significant difference between low expression and high expression of miR-143 in the overall survival of colon cancer patients. However, low expression of miR-143 was significantly associated with high event-free survival (hazard ratio (HR) 0.6; 95% confidence interval (CI) 0.40, 0.88). Low expression of miR-145 was associated with poor prognosis of patients (HR 1.92; 95% CI 1.45, 2.54); those with low expression of miR-145 were at 1.92-fold higher risk for short-term overall survival than those with high expression of miR-145. MiR-145 was an unfavorable factor for the prognosis of colorectal cancer. There were no significant differences between low expression of miR-145 and high expression of miR-143 in event-free survival. Conclusion: miR-143 and miR-145 have promising prognostic value for colorectal cancer. Low expression of miR-143 can predict high event-free survival, and low expression of miR-145 can predict poor overall survival.

Objective: The clinical implications of B7H1 and B7H4 in pancreatic cancer have been described however, the prognostic significance of these genes in pancreatic cancer patients remains inconclusive. The aim of the present study was to evaluate the prognostic role of B7H1 and B7H4 in pancreatic cancer patients. Methods: Electronic databases (PubMed, EMBASE, and the Cochrane Library) were searched for relevant articles published before May 2019. Meta-analyses were performed by pooling the hazard ratios (HRs) between overall survival or cancer-specific survival and high or low expression of B7H1/B7H4 in pancreatic cancer patients. Subgroup and sensitivity analyses were performed, and sources of variabilities were explored by performing meta-regression. Results: Sixteen studies (1434 patients’ data) were included. Compared with low expression, high expression of B7H1 was associated with significantly poor overall survival (HR 1.92 (95% confidence interval (CI) 1.35, 2.74); P<0.001) and cancer-specific survival (HR 2.46 (95% CI 1.55, 3.90); P<0.001). High expression of B7H4 also predicted poor overall survival (HR 2.38 (95% CI 1.89, 3.00); P<0.001). In subgroup analyses, a significant association between B7H1 and overall survival was observed for trials conducted in China (HR 2.08 (95% CI 1.29, 3.34)) but not in Japan (HR 1.98 (95% CI 1.33, 2.96)); or in studies with <50% patients having high expression (HR 2.02 (95% CI 1.40, 2.91)) but not in studies with >50% patients with high expression (HR 1.40 (95% CI 0.87, 2.26)). Conclusion: The current study suggests that high B7H1 and B7H4 expression is associated with a poor prognosis in pancreatic cancer patients.

Introduction We aimed to assess the effect of VEGF-A, PDGF-BB, and c-Met expression levels on survival in patients with metastatic colorectal cancer receiving bevacizumab therapies. Patients and methods A total of 105 patients diagnosed with metastatic colorectal cancer between the years 2006 and 2016 were included in the research retrospectively. Results The progression-free survival (PFS) durations of patients with high expression levels of VEGF-A and with low expression levels of VEGF-A were 11 months and 10 months (p = 0.44), respectively. The PFS durations of patients with high PDGF-BB expression and low PDGF-BB expression were 12 months and 10 months (p = 0.16), respectively, while the PFS durations of patients with high and low c-Met expression were 8 months and 13 months (p = 0.005), respectively. Metastatic overall survival was 27 months and 18 months (p = 0.05) in patients with high and low VEGF-A expression levels, respectively, 31 months and 21 months (p = 0.16) in patients with high and low PDGF-BB expression levels, respectively, and 21 months and 26 months (p = 0.11) in patients with high and low c-Met expression levels, respectively. Conclusion The results of this research revealed a high c-Met expression relationship with worse PFS and low VEGF-A expression associated with poor metastatic overall survival in patients with metastatic colorectal cancer receiving bevacizumab therapies.

Background: Colorectal cancer patients may be treated with several modalities and one of them is surgical treatment. Surgery in cancer patients is risky procedure and may not always resulted in prolonged survival. Therefore, before receiving any recommended treatment, the patient’s prognosis has to be assessed and defined properly. Several methods are available to assess the prognosis of cancer patients; one of them is the prognostic nutritional index (PNI).Objective: This study aimed to predict the survival of a colorectal cancer patient post-operatively by calculating the pre-operative PNI score.Method: Literature searching was done using inclusion and exclusion criteria on two databases, i.e. the PubMed and the Cochrane Library. The outcome was survival (disease-free survival, relapse-free survival, or overall survival).Results: Five articles that address the clinical question were retrieved. All indicated that a patient with low PNI score (<44.5) had a shorter overall survival (HR between 1.92 and 3.98 with all p values were <0.05).Conclusion: Pre-operative PNI score can be used to assess the overall survival of a colorectal cancer patient who underwent surgical resection. Patients with a PNI score > 44.5 had better survival than lower PNI score.

Abstract Background There have been controversial voices on if hepatitis B virus infection decreases the risk of colorectal liver metastases or not. This study aims to the find the association between HBV infection and postoperative survival of colorectal cancer and the risk of liver metastases in colorectal cancer patients. Methods Patients who underwent curative surgical resection for colorectal cancer between January 2011 and December 2012 were included. Patients were grouped according to anti-HBc. Differences in overall survival, time to progress, and hepatic metastasis-free survival between groups and significant predictors were analyzed. Results Three hundred twenty-seven colorectal cancer patients were comprised of 202 anti-HBc negative cases and 125 anti-HBc positive cases, and anti-HBc positive cases were further divided into high-titer anti-HBc group (39) and low-titer anti-HBc group (86). The high-titer anti-HBc group had significantly worse overall survival (5-Yr, 65.45% vs. 80.06%; P < .001), time to progress (5-Yr, 44.26% vs. 84.73%; P < .001), and hepatic metastasis-free survival (5-Yr, 82.44% vs. 94.58%; P = .029) than the low-titer group. Multivariate model showed anti-HBc ≥ 8.8 S/CO was correlated with poor overall survival (HR, 3.510; 95% CI, 1.718–7.17; P < .001), time to progress (HR, 5.747; 95% CI, 2.789–11.842; P < .001), and hepatic metastasis-free survival (HR, 3.754; 95% CI, 1.054–13.369; P = .041) in the anti-HBc positive cases. Conclusions Higher titer anti-HBc predicts a potential higher risk of liver metastases and a worse survival in anti-HBc positive colorectal cancer patients.

Background: A wealth of evidence has shown that microRNAs (miRNAs) can modulate specific genes, increasing our knowledge on the fine-tuning regulation of protein expression. miR-221 and miR-222 have been frequently identified as deregulated across different cancer types; however, their prognostic significance in cancer remains controversial. In view of these considerations, we performed an updated systematic review and meta-analysis of published data investigating the effects of miR-221/222 on overall survival (OS) and other secondary outcomes among cancer patients. A systematic search of PubMed, Web of Knowledge, and Cochrane Library databases was performed. Hazard ratios (HRs) and 95% confidence intervals (95% CIs) were used to assess the strength of association. Results: Fifty studies, analyzing 6086 patients, were included in the systematic review. Twenty-five studies for miR-221 and 17 studies for miR-222 which assessed OS were included in the meta-analysis. High expression of miR-221 and miR-222 significantly predicted poor OS (HR: 1.48, 95% CI: 1.14–1.93, p = 0.003 and HR: 1.90, 95% CI: 1.43–2.54, p < 0.001, respectively). Subgroup analysis revealed that the finding on miR-221 was not as robust as the one on miR-222. Furthermore, high miR-222 expression was also associated with worse progression-free survival and disease-free survival pooled with recurrence-free survival. Conclusions: The meta-analysis demonstrated that high expression of miR-222 is associated with poor prognosis in cancer patients, whereas the significance of miR-221 remains unclear. More work is required to fully elucidate the role of miR-221 and miR-222 in cancer prognosis, particularly in view of the limitations of existing results, including the significant heterogeneity and limited number of studies for some cancers.

Objective Prognostic prediction of colorectal cancer (CRC) remains challenging because of its heterogeneity. Aberrant expression of caudal-type homeobox transcription factor 2 (CDX2) is strongly correlated with the prognosis of CRC. Methods Tissue samples of patients with CRC who underwent surgery in Xinhua Hospital (Shanghai, China) from January 2010 to January 2013 were collected. CDX2 expression was semiquantitatively evaluated via immunohistochemistry. Results In total, 138 patients were enrolled in this study from a prospectively maintained institutional cancer database. The median follow-up duration was 57.5 months (interquartile range, 17.0–71.0 months). In the Cox proportional hazards model, low CDX2 expression combined with stage T4 CRC was significantly the worst prognostic factor for disease-free survival (hazard ratio = 7.020, 95% confidence interval = 3.922–12.564) and overall survival (hazard ratio = 5.176, 95% CI = 3.237–10.091). In the Kaplan–Meier survival analysis, patients with low CDX2 expression and stage T4 CRC showed significantly worse disease-free survival and overall survival than those with low CDX2 expression alone. Conclusion CDX2 expression combined with the T stage was more accurate for predicting the prognosis of CRC. Determining the prognosis of CRC using more than one variable is valuable in developing appropriate treatment and follow-up strategies.

Objective Characterize the survival impact of smoking on HPV-related (human papillomavirus) oropharyngeal squamous cell carcinoma. Data Sources Articles from 2000 to 2019 in the PubMed, Embase, and Cochrane Library databases were systematically reviewed for content and inclusion/exclusion criteria. Review Methods Two reviewers independently analyzed the databases for eligibility and quality of the articles. Demographic data, smoking history, and survival outcomes were recorded. Hazard ratios and 95% CIs were collectively analyzed through a random effects meta-analysis model. Results Fifteen articles were included in the meta-analysis for overall survival, disease-specific survival, disease-free survival, progression-free survival, and locoregional recurrence outcomes. The overall survival hazard ratio was 2.4 for ever having smoked (95% CI, 1.4-4.0; P = .0006, I2 = .384) and 3.2 for current smoking (95% CI, 2.2-4.6; P < .0001, I2 = 0). The hazard ratio for disease-specific survival in current smokers was 6.3 (95% CI, 1.3-29.3; P = .0194, I2 = 0). Ever smoking had a larger impact on overall survival and disease-specific survival than the 10–pack year smoking threshold. Conclusion Smoking negatively affects survival in patients with HPV-related oropharyngeal carcinoma across all outcomes. Current smoking during treatment is associated with the greatest reduction in survival, possibly secondary to diminished radiation therapy efficacy.

Purpose Adjuvant systemic chemotherapy administered after surgical resection of colorectal cancer metastases may reduce the risk of recurrence and improve survival, but its benefit has never been demonstrated. Two phase III trials (Fédération Francophone de Cancérologie Digestive [FFCD] Trial 9002 and the European Organisation for Research and Treatment of Cancer/National Cancer Institute of Canada Clinical Trials Group/Gruppo Italiano di Valutazione Interventi in Oncologia [ENG] trial) used a similar design and showed a trend favoring adjuvant chemotherapy, but both had to close prematurely because of slow accrual, thus lacking the statistical power to demonstrate the predefined difference in survival. We report here a pooled analysis based on individual data from these two trials. Patients and Methods After complete resection of colorectal liver or lung metastases, patients were randomly assigned to chemotherapy (CT arm; fluorouracil [FU] 400 mg/m2 administered intravenously [IV] once daily plus dl-leucovorin 200 mg/m2 [FFCD] × 5 days or FU 370 mg/m2 plus l-leucovorin 100 mg/m2 IV × 5 days [ENG] for six cycles at 28-day intervals) or to surgery alone (S arm). Results A total of 278 patients (CT, n = 138; S, n = 140) were included in the pooled analysis. Median progression-free survival was 27.9 months in the CT arm as compared with 18.8 months in the S arm (hazard ratio = 1.32; 95% CI, 1.00 to 1.76; P = .058). Median overall survival was 62.2 months in the CT arm compared with 47.3 months in the S arm (hazard ratio = 1.32; 95% CI, 0.95 to 1.82; P = .095). Adjuvant chemotherapy was independently associated with both progression-free survival and overall survival in multivariable analysis. Conclusion This pooled analysis shows a marginal statistical significance in favor of adjuvant chemotherapy with an FU bolus–based regimen after complete resection of colorectal cancer metastases.

Abstract Background: Ewing's sarcoma (ES) is the second most prevalent malignancy among bone tissue tumors, and there is no adequate prognosis biomarker. The protein encoded by CCT6A is a molecular chaperone. Early studies have suggested that CCT6A is involved in the development of many cancers, however, there is no clear evidence of a role for CCT6A in ES.Methods: In this study, we performed a bioinformatics analysis of 32 Ewing sarcoma specimens from the GSE17618 dataset for differences in gene expression and overall survival, event-free survival, and gene expression in different subgroups. Results: After three screenings, we identified CCT6A as highly correlated with Ewing's sarcoma prognosis. Survival analysis showed low overall survival (OS) for CCT6A high expression (P=0.024). On the other hand, Cox regression analysis showed that CCT6A expression, event-free survival (EFS), and age were strongly associated with the prognosis of Ewing sarcoma, identified as independent poor prognostic biomarkers. (CCT6A: P=0.015; Age: P-value=0.026; EFS: P-value=0.001). Conclusion: The expression level of CCT6A is strongly associated with the prognosis of Ewing's sarcoma. High expression of the CCT6A gene may serve as a biomarker for poor prognosis in patients with Ewing's sarcoma.
