ABSTRACT
Objective To investigate clinieopathologic characteristics and therapy of local advanced welldifferentiated thyroid carcinoma.Methods Data of 23 cases of advanced well-differentiated thyroid carcinoma treated from Jan.1996 to Dec.2005 were retrospectively reviewed.The data included age,pathologic type,local invasion,operative plan,postoperative complications and survival duration.Results Histology showed there were 15 cases of papillary carcinoma,6 ca8es of follicular carcinoma,and 2 cases of papiIlary follicular carcinoma.8 cases had local invasion into recurrent laryngeal nerve,12 cases had invasion into trachea,3 cases had trachea and esophagus invasion,and 8 cases had suprahyoid muscle invasion.All the 23 cases underwent resection procedure.According to surgical procedure,they were divided into radical resection group(n=6),tumor resection group(n=14)and tumor debulking group(n=3).2 cases received radiotherapy after thyroidectomy in tumor debulking group.All patients were followed up.Overall survival rate after 1 year,3 years and 5 years Was 91.3%(21/23),82.6%(19/23),and 60.8%(14/23)respectively.Prognosis of radical tumor removal group and tumor resection group was obviously better than that of tumor debulking group.Conclusions Prognosis is good for local advanced well-differentiated thyroid carcinoma patients receiving resection.Protection of local organ function Can enhance postoperative life quality.
ABSTRACT
Objective To study the relationship between fragile histidine traid (FHIT), pituitary tumor transforming gene-1 (PTTG-1) in thyroid tumor tissue. Methods The expression of FHIT and PTTG-1 were detected by immunohistocbemistry in 96 eases (56 carcinoma,40 adenoma). Results Compared with thyroid adenoma, the expression of FHIT decreased (P <0.01) ,PTTG-1 increased in thyroid carcinoma(P <0.01). The expression of FHIT is different in thyroid carcinoma in eancerometastasis to non-cancerometastasis (P < 0. 01), prognosis index (≥65) and prognosis index(< 65) (P < 0.01 and P < 0.05) ; There also was statistically significant differences between the expression of PTTG in thyroid carcinoma (P <0.05 and P <0.01). Conclusion FHIT and FTTG-1 may be an important reference significance in the differentiation of benign and malignant thyroid tumor tissue, and may serve as useful prognostic markers.
