Malignant tumors of major salivary gland origin. A matched-pair analysis of the role of combined surgery and postoperative radiotherapy 总被引:1,自引:0,他引:1

Between 1966 and 1982, 46 patients with previously untreated malignant tumors of major salivary gland origin received combined surgery and postoperative radiotherapy. They were compared with 46 patients treated with surgery only between 1939 and 1965, who were matched according to prognostic criteria. Radiation doses ranged from 4000 to 7740 cGy (median, 5664 cGy). The 5-year determinate survival rates for patients given combined therapy with stage I and II disease vs patients given surgery only was 81.9% vs 95.8%, while for stages III and IV it was 51.2% vs 9.5%, respectively. Local control for stage III and IV disease in patients given combined therapy vs patients given surgery only at 5 years was 51.3% vs 16.8%. For patients with nodal metastases, 5-year determinate survival for the combined-therapy group vs the surgery-only group was 48.9% vs 18.7%, and the corresponding local-regional control was 69.1% vs 40.2%. The results of this analysis suggest that postoperative radiotherapy significantly improves outcome for patients with stage III and IV disease and for patients with lymph node metastases. 相似文献

Cost effectiveness of tinzaparin sodium versus unfractionated heparin in the treatment of proximal deep vein thrombosis 总被引:2,自引:0,他引:2
OBJECTIVE: To evaluate economic and health implications of tinzaparin sodium, a once a day low-molecular-weight heparin (LMWH), versus unfractionated heparin (UFH) in the treatment of acute deep vein thrombosis (DVT) from a US healthcare payer perspective. STUDY DESIGN: An economic model, composed of two submodules, was created: A short-term module based on clinical trial data covering the first 3 months and a long-term module that projects trial results based on published data for up to 50 years. METHODS: Clinical trial results were combined with data from long-term follow-up studies of DVT in a model that estimates the health and economic consequences of treatment. Both short- and long-term costs with tinzaparin sodium were compared with UFH, as were health outcomes and quality-adjusted life-years (QALYs). RESULTS: Patients treated with tinzaparin sodium are estimated to live a mean of 0.9 years longer on average (0.6 discounted), resulting in an increase of 0.8 QALYs (0.5 discounted). At the same time, lifetime savings are US dollars 621 per patient (1999 values), even when all patients receiving tinzapirin sodium are treated as inpatients. Early discharge of patients receiving tinzaparin sodium, or outpatient treatment, would save between US dollars 3000 and US dollars 5000 per patient. CONCLUSION: Tinzaparin sodium leads to better health outcomes and substantial economic savings compared with UFH treatment when all management costs are considered. 相似文献

This study followed 345 Israeli youngsters who had been residents of two shelters for runaway and homeless youths, 6-12 weeks after their departure. Telephone interviews were conducted with the youngsters, their parents, and social workers in the community. A majority of the youngsters had either returned to their family homes, or had been placed out of home. Their residential stability was found to be low. Post-shelter place of residence was related to length of stay at the shelter, amount of contact with their family while at the shelter, and manner of departure. Our findings lead to a typology of shelter uses, and also raise questions about the extent to which shelters achieve their declared goals. 相似文献

OBJECTIVE: We have recently demonstrated that fibrin induces a specific, dose- and time-dependent upregulation of the angiogenic factor interleukin 8 (IL-8) from human oral squamous cell carcinoma (OSCC) cells in vitro. In this study we begin to test the hypothesis that fibrin induces IL-8 expression from tumor cells in vivo by studying their in vivo association in OSCC. STUDY DESIGN: The presence of fibrin(ogen) was initially evaluated in 20 archival human OSCCs by means of immunohistochemistry with a polyclonal antibody. The presence of fibrin and IL-8 was then studied in 19 sections from 8 different patients' head and neck tumors (including 6 OSCCs) by means of immunohistochemistry with a monoclonal antibody against fibrin. These 8 tumors had been treated with inhibitors of new fibrin formation and degradation immediately after surgical removal. RESULTS: Fibrin staining was found in 100% of the tumor sections tested. IL-8 staining was found in the cytoplasm of tumor cells in 100% of the studied tumors, including areas adjacent to fibrin. CONCLUSIONS: These data demonstrate an in vivo association between fibrin and IL-8 in OSCC. These studies support our hypothesis that fibrin induces expression of protumorigenic factors such as IL-8 from tumor cells in vivo. 相似文献

An effective transition of the psychiatric patient from the hospital to the community clinic is vital to the continuity of care. This study shows a short-term group, the "re-entry group," to be more effective in this transition than are patients discharged from a psychiatric hospital by the traditional process. We used a psychoeducational approach to facilitate active participation and compliance with outpatient therapy. Outcome variables included absorption of patients into the clinic, continued therapy, compliance with treatment, rehospitalization, level of knowledge regarding illness and medication, quality of rehabilitation, and attitude towards treatment. 相似文献

A case of unilateral cerebellar hypoplasia is presented. This was an incidental finding in a patient with no evidence of neuromuscular or metabolic disease and no past history of trauma, anoxia, or perinatal difficulties. Computed tomographic scans showed posterior fossa asymmetry with underlying unilateral cerebellar hemisphere hypoplasia. In addition, there was overlying skull table thickening and excess petrous pneumatization on the affected side. 相似文献
