RESUMEN
OBJECTIVE@#To analyze the clinic and pathologic data of thymic epithelial tumor (TET) and to explore its prognostic factors.@*METHODS@#From June 1997 to September 2007, 137 patients with TET were surgically treated in our hospital. The data included age, gender, symptoms, histological type, stage and grade, pathological findings, and operation reports. The patients were followed up by telephones and mails. The patients were divided into Masaoka I/II group and III/IV group, and WHO A/AB/B1 group and B2/B3/C group. Kaplan-Meier method, log-rank test, and COX regression model were used to analyze the prognostic factors for TET.@*RESULTS@#Among the 137 patients, 124 (90.5%) received complete resection, 9 (6.6%) incomplete resection, and 4 (2.9%) surgical biopsy. The rate of complete resection was significantly higher in Masaoka stages I/II than that in stages III/IV (P<0.001). The overall 5-year and 10-year survival rate was 71.4å and 50.1å, respectively. Patients in stage I/II had better long-term survival than those in stage III/IV (P<0.001). According to WHO histological classification, the 5-year and 10-year survival rate in patients with Type A/AB/B1 TET was significantly higher than that in patients with Type B2/B3/C TET (P<0.001). The 5-year and 10-year survival rate in patients with complete resection was significantly higher than that in patients with incomplete resection and biopsy (P<0.001).Cox regression analysis showed that the prognosis of patients with TET was related to Masaoka stage, WHO histological classification, extent of resection, and age at operation.@*CONCLUSION@#Masaoka stage, WHO histological classification, extent of resection, and age at operation are important prognostic factors in patients with TET.

Objective To study the expressions of human telomerase reverse transcriptase (hTRT) mRNA and Bax protein in different types of papillary thyroid carcinoma (PTC). Methods hTRT mRNA was detected using in situ hybridization, and Bax protein was detected by immunohistochemistry. Results The positive rates of hTRT were 86.21%,68.97%, 93.33%, 96.43% and 41.79% in PTC, papillary microcarcinoma, intra-thyroid carcinoma, extra-thyroid carcinoma and adjacent tumor tissues, respectively. The positive rate of hTRT expression in the cancer tissues was significantly higher than that in the adjacent tumor tissues (P
RESUMEN
Objective To study on the expressions of bFGF, PDGF and TSP-1 mRNA in small intestinal carcinoma and adenoma and their clinico-pathological significance. Methods The specimens were continuously sliced into pieces. The expression of bFGF, PDGF and TSP-1 mRNA was determined by in situ hybridization. Results bFGF, PDGF and TSP-1 was positive in 57%,48% and 36% respectively in 44 cases of small intestinal adenocarcinoma, and was 20%, 30% and 90% in 10 of adenoma respectively. The positivity rates of bFGF mRNA and PDGF mRNA were significantly lower in adenocarcinoma of Ⅰ～Ⅱ grade, without invading muscular layer or invading superficial layer, maximal diameter of tumor mass
RESUMEN
Objective To explore the role and significance of the expressions of vascular endothelial growth factor-C(VEGF-C) and its receptors Flt-4 in metastasis of papillary thyroid carcinoma(PTC).Methods The expression levels of VEGF-C and Flt-4 were detected in 87 cases of PTC with SABC immunohistochemical method.Results Among 87 cases of PTC,the positive rates of VEGF-C and Flt-4 were 89.66%(78/87) and 81.61%(71/87),respectively.There was positive correlation between the expression of VEGF-C and Flt-4.The expression of VEGF-C in lymph node metastasis group was significantly higher than that of no lymph node metastasis group(P
