RESUMEN
OBJECTIVE@#To summarize the clinical effect of TPF regimen in the treatment of hypopharyngeal carcinoma and explore various clinical factors affecting treatment efficacy.@*METHOD@#The clinical data of 20 cases with hypopharyngeal carcinoma, who received TPF treatment, were analyzed retrospectively. After two courses of chemotherapy, based on radiographic outcomes, next treatment plan was developed. To sum up the clinical information, including the clinical type, patterns of tumor growth, pathologic type, tumor stage, lymph node metastasis, age and so on. To analyze possible influencing factors affecting curative effect.@*RESULT@#(1) After 20 cases with hypopharyngeal carcinoma received two courses of TPF treatment, the effect was evaluated. Objective response rate was 65%. (2) In patients with hypopharyngeal carcinoma, the efficacy of TPF therapy was significantly related to the clinical type, patterns of tumor growth and pathologic type; there was no statistical significance in tumor stage, lymph node metastasis and age.@*CONCLUSION@#According to the clinical type, patterns of tumor growth and pathologic type of hypopharyngeal carcinoma, resistance to chemotherapy in hypopharyngeal carcinoma can be assessed, which provides important basis for designing individualized treatment plan.

Objective To explore the expression and significance of Dickkopf-1 (Dkk-1) and cell lymphoma/leukemia-2 (Bcl-2) protein in sinonasal squamoucell carcinoma(SNSCC) .MethodThe immunohistochemical SP method and Western blomethod were adopted to determine the expression of Dkk-1 and Bcl-2 in 30 specimenof SNSC(SNSCgroup) ,38 specimenof sinonasal inverted papillomas(SNIP group) and 20 specimenof middle turbinate mucosa(control group) .ResultThe expression of DKK-1 protein in the SNSCgroup wasignificantly down-regulated compared with the SNIP group and the control group ,while the expression of Bcl-2 protein in the SNSCgroup wasignificantly up-regulated compared with the SNIP group and the control group;in the SNSCgroup ,the positive rateof DKK-1 protein and Bcl-2 protein in the high and middle differentiation group and the low differentiation group were 100 .00% ,68 .75% ,33 .33% and 50 .00% ,62 .50% ,100 .00% respectively ,the differencewere statistically significan(P<0 .05) .Conclusion Dkk-1 protein may play an importanpromoting role in the developmenand pro-gression procesof SNSC,the expression of Dkk-1 protein hanegative correlation with the expression of Bcl-2 protein in SNSC,which may become new targespoof SNSCgene therapy .
RESUMEN
OBJECTIVE@#To investigate the expression of Dickkopf-1 and GATA-6 in laryngeal carcinoma and to discuss their relevance and the roles in carcinogenesis and development of laryngeal carcinoma.@*METHOD@#Immunohistochemical technique was used to detect the expression of Dickkopf-1 and GATA-6 protein in 48 tissues of larynge al carcinoma, 48 para-carcinoma tissues and 20 normal laryngeal mucosal tissues.@*RESULT@#(1) The expression of Dick kopf-1 protein in laryngeal cancer is significantly lower than in para-carcinoma tissues and normal laryngeal mucosa tissues (P < 0.05). (2) The expression of GATA-6 protein in laryngeal cancer is significantly higher than in para-carcinoma tissues and normal laryngeal mucosa tissues (P < 0.05). (3) The expression of Dickkopf-1 and GATA-6 protein in laryngeal cancer is correlated with lymph node metastasis, clinical stage, histological grade (P < 0.05). (4) The expression of Dickkopf-1 and GATA-6 are negatively correlated in laryngeal cancer.@*CONCLUSION@#The expression of Dickkopf-1 and GATA-6 may contribute to the carcinogenesis and development of laryngeal carcinoma.

OBJECTIVE@#To investigate the expression of EMS1 and DcR3 in laryngeal carcinoma and analyze the relation of EMS1 and DcR3.@*METHOD@#The expression of EMS1 and DcR3 protein in 41 laryngeal carcinoma fresh samples and 41 para-carcinoma tissues (to cutting margin > 0.5 cm) were measured by flow cytometry, and 15 normal laryngeal mucosa samples were also studied as controls.@*RESULT@#(1) The quantitative and qualitative expression of EMS1 and DcR3 protein in laryngeal carcinoma tissues was obviously higher than those in para-carcinoma and in normal laryngeal mucosa tissues respectively (P < 0.05). There was no significant difference between the expression of para-carcinoma and normal laryngeal mucosa tissues. (2) In laryngeal carcinoma, the expression of EMS1 and DcR3 protein was independent of patients' clinical classification, tumor size, smoking history, patients' age and sex but associated with tumor metastasis, pathological grade and clinical stage. (3) In laryngeal carcinoma, the expression of EMS1 was positively correlated with that of DcR3.@*CONCLUSION@#EMS1 was positively related to DcR3, which might play an important role in the carcinogenesis and development of laryngeal carcinoma by synergic effect.
