Objective To investigate the prognostic significance of lysyl oxidase (LOX) expression in laryngeal cancer. Study Design Retrospective chart review and histologic analysis. Setting Tertiary referral academic center. Subjects and Methods Patients (N = 100) underwent surgical treatment for laryngeal cancer and had tissue specimens available. Immunohistochemical staining for LOX was performed on laryngeal cancer tissue microarrays, and the proportion and intensity of staining were evaluated. Patients with LOX scores ≤6 were classified into the low LOX group, while those with scores >6 were classified into the high LOX group. We analyzed the correlation between LOX expression and clinical factors as well as prognosis. Results LOX was predominantly expressed in the cytoplasm and nuclei of tumor cells. Kaplan-Meier analysis revealed that the high LOX group had worse overall survival and recurrence-free survival rates than the low LOX group ( P < .05). LOX expression exhibited marginally significant correlation with lymph node metastasis. In the Cox regression analysis, LOX expression and lymph node metastasis were significant factors correlated with overall survival rate (odds ratio [OR] = 3.92, 95% confidence interval [95% CI]: 1.35-11.37, P = .012; OR = 1.96, 95% CI: 0.93-1.43, P = .024, respectively). LOX expression was related to distant metastasis free survival rate (OR = 7.72, 95% CI: 1.02-19.18, P = .048). Conclusion A high expression level of LOX is associated with lymph node and distant metastasis as well as poor prognosis among patients with laryngeal cancer.

Emerging evidence have indicated that dysregulated long noncoding ribonucleic acids act as a novel diagnostic and therapeutic target in the progression of ovarian cancer. Long noncoding RNA DiGeorge syndrome critical region gene 5 has been reported to participate in some types of human cancer progresses, but its clinical roles in ovarian cancer had been rarely reported. This study aimed to explore the expression, clinicopathological features, diagnostic, and prognostic values of DiGeorge syndrome critical region gene 5 in ovarian cancer. The total levels of DiGeorge syndrome critical region gene 5 transcript variant 1 (NR_002733.2) and 2 (NR_045121.1) in patients with ovarian cancer were determined by quantitative reverse transcription polymerase chain reaction. The correlation of DiGeorge syndrome critical region gene 5 expression with clinicopathological factors was statistically analyzed by χ2 test. Overall survival analysis was carried out with the Kaplan–Meier curves with the log-rank test. Univariate and multivariate Cox regression analyses were performed to identify the prognostic significance of DiGeorge syndrome critical region gene 5 expression. Receiver operating characteristic curves were constructed to estimate the diagnostic and prognostic usefulness of DiGeorge syndrome critical region gene 5 in ovarian cancer. Results showed that relative DiGeorge syndrome critical region gene 5 expression was reduced by 36.81% and 65.79% in ovarian cancer tissues of patients and Gene Expression Omnibus DataSets (GSE119056) in contrast to normal tissues, respectively. Patients with lymph node metastasis and distant metastasis exhibited lower levels of DiGeorge syndrome critical region gene 5 in contrast to those patients with non-lymph node metastasis and non-distant metastasis, respectively. Low expression of DiGeorge syndrome critical region gene 5 was significantly associated with large tumor size, more lymph node metastasis, present distant metastasis, advanced clinical stage, and short overall survival in patients with ovarian cancer. Low expression of DiGeorge syndrome critical region gene 5 was an independent unfavorable prognostic factor for overall survival in patients with ovarian cancer. Receiver operating characteristics curves for prognosis yielded significant area under curves for lymph node metastasis, clinical stage, and overall survival. In conclusion, our study demonstrated that downregulated DiGeorge syndrome critical region gene 5 may be a new promising biomarker for predicting clinical progression and prognosis in patients with ovarian cancer.

Introduction: Mucoepidermoid carcinoma (MEC) is a common salivary gland malignancy. As studies reported on large cases of mucoepidermoid carcinoma of the parotid glands are few, this paper aims to research the effects of clinical and pathological factors, such as applying concentrated growth factor (CGF) on repairing and cervical lymph node metastasis, on the prognosis of mucoepidermoid carcinoma of the parotid gland. Methods: The retrospective analysis of prognostic factors was conducted based on 176 cases with mucoepidermoidcarcinoma of the parotid gland, who received treatment at the Affiliated Hospital of  Chengde Medical College during the period of March 2000 to March 2012. Results: The Five-year overall survival rate was 75.57%, while the Five-year tumor-free survival rate was 64.77%. Univariate analysis showed that the influential factors for the prognosis of mucoepidermoid carcinoma of the parotid gland included surgical approach, tumor size, clinical stage, pathological grade, lymph node metastasis, and distant metastasis, etc; among which pathological grade, lymph node metastasis, and distant metastasis were indicated by multivariate analysis to be the independent risk factors. Conclusion: The survival rate of mucoepidermoid carcinoma of the parotid gland is relatively high. Lymph node metastasis, pathological grade, and distant metastasis are the independent risk factors that affect the prognosis of patients with mucous epidermis carcinoma of the parotid gland.

A large number of literature has shown that high expression of X inactive-specific transcript (XIST) is associated with poor prognosis and metastasis of cancer in patients. However, most of this literature is limited by the small sample sizes and discrete outcomes. Therefore, a meta-analysis was performed to investigate the relation between XIST expression and tumor node metastasis (TNM) stage, lymph node metastasis, distant metastasis, and overall survival of cancer patients. We searched for literature in PubMed, Embase, and Web of Science. The pooled hazard ratios (HRs) or odds ratios (ORs) with 95% confidence intervals (CIs) were calculated to evaluate the association of XIST expression with prognosis and clinicopathological characteristics of cancer patients. Finally, a total of 14 articles involving 1123 patients were included in this meta-analysis. The results suggested that high expression of XIST has a significant relationship with a relatively poor overall survival for patients with malignant tumors (HR 1.82; 95% CI 1.32, 2.52; P = 0.0003). Moreover, high expression of XIST was significantly associated with poor TNM stage (OR 3.64; 95% CI 2.62, 5.07; P < 0.0001), lymph node metastasis (OR 2.39; 95% CI 1.65, 3.46; P < 0.0001) and distant metastasis (OR 2.84; 95% CI 1.90, 4.23; P < 0.0001). In conclusion, high expression of lncRNA XIST may be a predictive factor of poor prognosis in human cancers.

The double-stranded RNA-binding protein TARBP2 has been suggested to act as an upstream regulator of breast cancer metastasis by destabilizing transcripts of the possible metastasis suppressors amyloid precursor protein (APP) and ZNF395. We examined this hypothesis by immunostaining of TARBP2, APP, and ZNF395 in 200 breast cancer specimens using tissue microarrays and analyzed the relationships between expression levels and clinicopathological parameters and prognosis. Increased TARBP2 overexpression was associated with shorter overall survival and disease-free survival, and increased but not reduced APP expression correlated with lower overall survival and disease-free survival. ZNF395 expression levels had no prognostic value, but reduced expression correlated with reduced lymph node metastasis. There was no significant relationship between TARBP2 overexpression and reduced APP and/or ZNF395 expression. Patients with tumors with higher TARBP2 or APP expression had unfavorable prognoses. Although reduced ZNF395 expression was significantly related to reduced lymph node metastasis, further studies are needed to clarify the role of TARBP2/APP/ZNF395 in breast cancer.

Abstract Background The present study aimed to investigate the prognostic effect of CD38 in patients with esophageal squamous cell carcinoma (ESCC). Methods We performed a retrospective cohort study by consecutively recruiting 142 patients with ESCC. The clinicopathological features and expression of CD38, CD4, CD8, Ki-67, PD-L1 and PD-1 in tumor and immune cells were independently evaluated by two pathologists. Results CD38 was expressed in immune cells but not tumor cells and the median expression rate of CD38 in immune cells was 60%. Among ESCC patients with perigastric lymph node metastasis, the expression rate of CD38 was not associated with the disease-free survival (p = 0.207), but had a significant association with the overall survival (p = 0.042). The median overall survival was 13 months and not observed among patients with low and high expression rate of CD38, respectively. The crude and adjusted hazard ratio (HR) of high CD38 expression was 0.37 (95%CI 0.14, 0.95) and 0.21 (95%CI 0.06, 0.70). The expression rate of CD38 had a negative correlation with PD-L1 expressed in tumor cells and CD4 expressed in immune cells. Among patients without perigastric lymph node metastasis, the expression rate of CD38 showed a significant association with the disease-free survival (p < 0.05). The median disease-free survival was 45 months and not achieved for patients with high and low expression of CD38; the adjusted HR of high CD38 expression was 2.13 (95%CI 0.85, 5.33). CD38 did not have significant association with the overall survival for patients without perigastric lymph node metastasis. The expression rate of CD38 had a negative correlation with PD-L1 expressed in tumor cells and a positive correlation with PD-L1 expressed in immune cells. Conclusion The high expression rate of CD38 was associated with a better survival for ESCC with perigastric lymph node metastasis. The prognostic effect of CD38 on esophageal cancer should be warranted in future prospective studies.

Abstract Background: Ovarian cancer (OC) is one lethal gynecologic cancer, with a 5-year survival rate approximately 47% and localized stage diagnosis of 15%. Circular RNAs are promising biomarkers for malignancies. Methods: CiRS-7 expression was confirmed in 40 paired OC and normal adjacent tissues from 40 OC patients with different TNM stages, lymph node metastasis status and overall survival rate, also 5 different OC cell lines by qRT-PCR. Effects of ciRS-7 silence on OC cell phenotypes were determined in OC cells and Xenograft mouse model. StarBase was used to predict binding sites between ciRS-7 and micRNAs. Pearson correlation analysis and RNA-immunoprecipitation assay were used to determine the association between genes. Point mutation and rescue experiments were applied for molecular mechanism investigation. Results: CiRS-7 expression was significantly higher in OC cells and tissues, which was significantly associated with the TNM stages, lymph node metastasis status and overall survival rate in OC patients. CiRS-7 silence inhibited OC cell growth and metastasis. CiRS-7 sponged miR-641 to up-regulate ZEB1 and MDM2 expression in OC development. Conclusion: CiRS-7 serves as a competing endogenous RNA of miR-641 that promoted cell growth and metastasis in OC, via regulating ZEB1 and MDM2-mediated EMT. High ciRS-7 expression was a poor prognosis of TNM stages, lymph node metastasis status and overall survival rate in OC patients. Targeting ciRS-7/miR-641/ZEB1 or ciRS-7/miR-641/MDM2 axis may be a novel diagnostic, prognostic and therapeutic strategy for OC.

Objectives: The aim of this study was to assess the number of tumour-infiltrating lymphocytes (TILs) and the expression of Programmed Cell Death 1 Ligand 1 (PD-L1) in Acinic Cell Carcinoma (AciCC) of the salivary glands, to enable a correlation with clinico-pathological features and to analyse their prognostic impact. Methods: This single centre retrospective study represents a cohort of 36 primary AciCCs with long-term clinical follow-up. Immunohistochemically defined immune cell subtypes, i.e., those expressing T-cell markers (CD3, CD4 and CD8) or a B-cell marker (CD20) were characterized on tumour tissue sections. The number of TILs was quantitatively evaluated using software for digital bioimage analysis (QuPath). PD-L1 expression on the tumour cells and on immune cells was assessed immunohistochemically employing established scoring criteria: tumour proportion score (TPS), Ventana immune cell score (IC-Score) and combined positive score (CPS). Results: Higher numbers of tumour-infiltrating T- and B- lymphocytes were significantly associated with high-grade transformation. Furthermore, higher counts of T-lymphocytes correlated with node-positive disease. There was a significant correlation between higher levels of PD-L1 expression and lymph node metastases as well as the occurrence of high-grade transformation. Moreover, PD-L1 CPS was associated with poor prognosis regarding metastasis-free survival (p = 0.049). Conclusions: The current study is the first to demonstrate an association between PD-L1 expression and lymph node metastases as well as grading in AciCCs. In conclusion, increased immune cell infiltration of T and B cells as well as higher levels of PD-L1 expression in AciCC in association with high-grade transformation, lymph node metastasis and unfavourable prognosis suggests a relevant interaction between tumour cells and immune cell infiltrates in a subset of AciCCs, and might represent a rationale for immune checkpoint inhibition.
