RESUMO
Objective:To investigate the expressions of lysine specific demethylase 1 (LSD1) and podoplanin (PDPN) in tongue squamous cell carcinoma and the correlation between LSD1 or PDPN and clinicopathological characteristics or prognosis.Methods:A total of 67 cases of tongue squamous cell carcinoma and corresponding paracancerous normal tissues in the First Affiliated Hospital of Xinjiang Medical University from January 2011 to January 2016 were selected. The expressions of LSD1 and PDPN in cancer and paracancerous tissues were detected by immunohistochemical method, and the patients were followed up for a long time to analyze the correlation between the expression of LSD1 or PDPN and clinicopathological characteristics or prognosis.Results:The expressions of LSD1 and PDPN in tongue squamous cell carcinoma tissues were higher than those in paracancerous tissues, and the differences were statistically significant ( Z=6.089, P<0.001; Z=5.781, P<0.001). The expression intensities of LSD1 and PDPN were significantly different in patients with different clinical stage ( χ2=11.487, P=0.001; χ2=8.111, P=0.004), lymph node metastasis ( χ2=4.772, P=0.029; χ2=6.206, P=0.013) and tumor size ( χ2=5.985, P=0.014; χ2=4.247, P=0.039). The expression intensity of LSD1 was also significantly different in patients with different degrees of differentiation ( χ2=6.660, P=0.010). In univariate analysis, LSD1 expression intensity was negatively correlated with progression-free survival (PFS) and overall survival (OS) ( χ2=18.930, P<0.001; χ2=16.257, P<0.001), PDPN expression intensity was negatively correlated with PFS and OS ( χ2=31.720, P<0.001; χ2=18.390, P<0.001), and tumor size was negatively correlated with PFS and OS ( χ2=5.326, P=0.021; χ2=8.843, P=0.003). Postoperative radiotherapy and clinical stage were positively and negatively correlated with OS respectively ( χ2=4.197, P=0.040; χ2=6.355, P=0.012). In multivariate analysis, LSD1 was an independent risk factor for PFS and OS ( HR=5.743, 95% CI: 1.012-32.579, P=0.048; HR=17.759, 95% CI: 2.303-136.916, P=0.006), PDPN was an independent risk factor for PFS ( HR=4.380, 95% CI: 1.258-15.254, P=0.020), postoperative radiotherapy was a protective factor for PFS and OS ( HR=0.374, 95% CI: 0.157-0.895, P=0.027; HR=0.218, 95% CI: 0.091-0.521, P=0.001), and clinical stage was an independent risk factor for OS ( HR=2.637, 95% CI: 1.107-6.280, P=0.029). In tongue squamous cell carcinoma tissues, the expression of LSD1 was positively correlated with that of PDPN ( rs=0.655, P<0.001). Conclusion:The expressions of LSD1 and PDPN in tongue squamous cell carcinoma are higher than those in adjacent tissues. LSD1 is an independent risk factor for PFS and OS, PDPN is an independent risk factor for PFS, clinical stage is an independent risk factor for OS, and postoperative radiotherapy is a protective factor for PFS and OS. There is a positive correlation between the expressions of LSD1 and PDPN in tongue squamous cell carcinoma, and they can both be used as independent predictors of prognosis in patients with tongue squamous cell carcinoma.

Objective To analyze the therapeutic effects of different treatment modalities in patients with tongue squamous cell carcinoma.Methods A retrospective analysis was performed on the complete clinical and follow-up data of 132 patients with pathologically confirmed tongue squamous cell carcinoma,who were initially treated at the First Affiliated Hospital of Xinjiang Medical University from 2003 to 2011.The Kaplan-Meier method was used to calculate the overall survival (OS) rates for patients who received surgery alone (S),radiotherapy alone (R),surgery plus radiotherapy (S + R),chemotherapy plus surgery (C + S),chemotherapy plus radiotherapy (C + R),and surgery,radiotherapy,and chemotherapy (S + R + C).The OS was compared between these groups by log-rank test.Multivariate analysis was performed using the Cox proportional hazard model to establish independent treatment modalities as prognostic factors.Results The follow-up rate was 100％.The 3-year sample size was 94.The 3-year OS rate for all patients was 72.7％.The univariate analysis showed that among 70 stage Ⅰ and Ⅱ patients,the S,R,S + R,C + S,and S + R + C groups had 3-year OS rates of 86％,67％,97％,100％,and 82％,respectively (P =0.018) ;among 62 stage Ⅲ and Ⅳ patients,the S,R,S + R,C + S,C + R,and S + R + C groups had 3-year OS rates of 38％,14％,92％,40％,14％,and 67％,respectively (P =0.000).The multivariate analysis showed that S + R and S + R + C were independent prognostic factors (P =0.000 and 0.005).onclusions Surgery alone or combination therapy including surgery has a good therapeutic effect for stage Ⅰ-Ⅱ tongue squamous cell carcinoma,while S + R and S + R + C are better treatment modalities for stage Ⅲ-Ⅳ disease;however,advanced patients have a poor prognosis after being treated with R and C + R modalities.
RESUMO
Objective To evaluate the treatment outcome and prognostic factors in patients with grade Ⅲ/Ⅳ glioma following postoperative chemoradiotherapy.Methods A retrospective analysis was performed on the medical records of 119 patients with grade Ⅲ/Ⅳ glioma who received treatment in our hospital from January 2007 to April 2012.Of the 119 patients,49 received radiotherapy alone,21 received radiotherapy combined with nitrosoureas,and 49 received radiotherapy combined with temozolomide.The Kaplan-Meier method was used to calculate overall survival (OS) rates and recurrence rates.The Cox regression model was used for multivariate prognostic analysis.Results The follow-up rate was 94.1％.Fifty-three patients were followed up for at least 1 year,and 10 for at least 2 years.The overall recurrence rate was 69.7％.The 1-and 2-year OS rates were 44.5％ and 8.4％,respectively.The multivariate analysis showed that age,presence or absence of seizures before surgery,extent of tumor resection,and radiotherapy plus concurrent and adjuvant temozolomide were the main prognostic factors for tumor recurrence (P =0.002,0.005,0.000,and 0.000).The above factors and the pathological grade of tumor were the independent prognostic factors for patients' survival (P =0.006,0.010,0.000,0.000,and 0.001).Conclusions Postoperative radiotherapy plus concurrent and adjuvant temozolomide produce a good clinical effect in patients with grade Ⅲ/Ⅳ glioma.Age of ＜ 60 years,no seizures before surgery,total tumor resection,and pathological grade Ⅲ of tumor are the favorable prognostic factors for the long-term survival in patients with malignant glioma.
