AbstractThis study aimed to assess the prognostic value of MRI-measured tumor thickness (MRI-TT) in patients with tongue squamous cell carcinoma (SCC). This single-center retrospective cohort study included 133 pathologically confirmed tongue SCC patients between January 2009 and October 2019. MRI measurements of tongue SCC were based on axial and coronal T2-weighted (T2WI) and contrast-enhanced T1-weighted (CE-T1WI) images. Two radiologists independently measured MRI-TT. Intraclass correlation coefficients (ICC) were calculated for inter-rater agreements. Spearman’s rank correlation between MRI-TT and pathologic depth of invasion (pDOI) was assessed. Cox proportional hazards analyses on recurrence-free (RFS) and overall survival (OS) were performed for MRI-TT and pDOI. Kaplan–Meier survival curves were plotted with log-rank tests. The intra- and inter-rater agreements of MRI-TT were excellent (ICC: 0.829–0.897, all P < 0.001). The correlation between MRI-TT and pDOI was good (Spearman’s correlation coefficients: 0.72–0.76, P < 0.001). MRI-TT were significantly greater than pDOI in all axial and coronal T2WI and CE-T1WI (P < 0.001). In multivariate Cox proportional hazards analysis, MRI-TT measured on axial CE-T1WI yielded a significant prognostic value for OS (hazards ratio 2.77; P = 0.034). MRI-TT demonstrated excellent intra- and inter-rater agreements as well as high correlation with pDOI. MRI-TT may serve as a prognostic predictor in patients with tongue SCC.

Abstract Background B7-h6, a member of the B7 family molecules, participates in the clearance of tumor cells by binding to NKp30 on NK cells. The expression of B7-H6 in esophageal squamous cell carcinoma and the clinical significance is unknown. The goal of this study was to determine the expression of B7-H6 in esophageal squamous cell carcinoma and the clinical significance of B7-H6 expression. Patients and methods We retrospectively collected clinical data from 145 patients diagnosed with esophageal squamous cell carcinoma between January 2007 and December 2008. These patients had all previously undergone surgical treatment for esophageal cancer, were clearly diagnosed, and had not received chemotherapy or radiotherapy. In addition, pathological tissue samples from the 145 patients were collected to detect the expression of B7-H6 by immunohistochemistry. The chi-square (χ2) test was used to analyse the relationships between B7-H6 and clinicopathological characteristics. The prognosis of the patients were analysed by Cox proportional hazards regression analysis and Kaplan-Meier analysis. Results B7-H6 was present in 133/145 (91.72%) of the esophageal squamous cell carcinoma samples and all localized in the cytoplasm. The expression level of B7-H6 was correlated with T stage (P=0.036) and lymphatic metastasis status (P=0.044). According to the results of the ROC curve analysis, H-score =90 was selected as the cut-off value. The 145 patients were divided into two groups, the high B7-H6 expression (H-score>90) group and the low B7-H6 expression (H-score≤90) group. Cox proportional hazards regression analysis indicated that tumour size (P=0.021), B7-H6 expression (P=0.025) and lymphatic metastasis status (P=0.049) were independent prognostic factors for esophageal squamous cell carcinoma. Kaplan-Meier analysis with the log-rank test demonstrated that the patients with high B7-H6 expression (P = 0.003), lymphatic metastasis (P <0.001) or a tumour size ≥ 3.0 cm (P = 0.001) had significantly worse survival than those with low B7-H6 expression, no lymphatic metastasis or a tumour size < 3.0 cm respectively. Conclusion B7-H6 is widely expressed in esophageal squamous cell carcinoma and high expression of B7-H6 can be used as a predictor of poor prognosis.

AbstractB7-H6, a member of the B7 family molecules, participates in the clearance of tumor cells by binding to NKp30 on NK cells. B7-H6 expression level in esophageal squamous cell carcinoma (ESCC) and the clinical value remain unknown. The goal of this study was to determine the expression of B7-H6 in ESCC and further explore its clinical significance. We retrospectively collected the clinical data of 145 patients diagnosed with ESCC between January 2007 and December 2008. The expression of B7-H6 of the pathological tissue samples was detected by immunohistochemistry. The chi-square (χ2) test was used to analyse the relationships of B7-H6 and clinicopathological characteristics. Survival and hazard functions were estimated using the Kaplan-Meier method, and survival between groups was compared using the two-sided log-rank test. The Cox proportional hazards regression model was used to adjust for the risk factors related to overall survival (OS). 133/145 (91.72%) of the ESCC tissue samples exhibited B7-H6 expression. The expression level of B7-H6 was correlated with T stage (P = 0.036) and lymphatic metastasis status (P = 0.044). High B7-H6 expression (P = 0.003) was associated with a significantly worse OS than low B7-H6 expression. Multivariate Cox proportional hazards regression analysis demonstrated that tumour size (P = 0.021), B7-H6 expression (P = 0.025) and lymphatic metastasis status (P = 0.049) were independent prognostic factors of OS for ESCC. Collectively, our findings suggest that B7-H6 is widely expressed in ESCC samples. And B7-H6 may represent a predictor of poor prognosis for ESCC.
