BACKGROUND: Quality of life (QOL) assessment has emerged to measure and quantify the balance between treatment benefit and toxicity, and has a value in predicting response and overall survival in cancer patients. METHODS: From July 1995 to February 1997, 38 symptomatic patients with advanced non-small cell lung cancer (NSCLC) were treated with MIP chemotherapy (mitomycin 6 mg/m2, ifosfamide 3000 mg/m2 and cisplatin 50 mg/m2 on day 1 every 3 weeks). Patients were assessed for QOL including physical well-being, general symptoms and lung cancer-specific symptoms, as well as objective response. RESULTS: The overall response rate was 38.9% (14/36, all were partial response) and the median duration of response was 3.5 months [95% confidence interval (CI) 2.0-4.0]. The median duration of overall survival was 7 months (95% CI 5.9-8.5). The overall improvement of QOL was 58.3% with 21 patients feeling better on treatment. The toxicity of chemotherapy was mild, mainly nausea/vomiting and minimal alopecia. Using multiple clinical predictors of survival (age, histology, stage, performance status), only change of QOL emerged significantly (P = 0.0007). CONCLUSIONS: MIP had an endurable response and low toxicity profile, and provided good QOL. Integral QOL data in our study provided the strong prediction of survival in advanced NSCLC. Further experienced QOL study will provide greatly enhanced outcome data in clinical trials.   相似文献

Kaposi's sarcoma-associated herpesvirus or human herpesvirus type8 (HHV-8) is present in all forms of Kaposi's sarcoma (KS) aswell as in primary effusion lymphomas and some cases of Castleman'sdisease. In KS tissues, HHV-8 is present in endothelial andspindle cells. Current serologic tests suggest that HHV-8 ispredominantly found in those at risk of KS and is not as widespreadas most other human herpesviruses. HHV-8 encodes various proteinsthat may play a role in promotion of cellular growth, includingcyclin- and G-coupled protein receptor homologues, and anti-apoptoticproteins, including Bcl-2, IL-6 (i.e., interleukin 6), and FLIP(i.e., FLICE inhibitory protein) homologues. In addition, HHV-8encodes two macrophage inflammatory-like proteins with anti-humanimmunodeficiency virus and angiogenic potential.  相似文献

Purpose: The aim of this study was to evaluate the role of FDG-CDET for the detection of primary oesophageal tumour, lymph node involvement and distant extension before surgery.Methods and patients: In patients fasting for 6h or more, 150-250 MBq of 18F-FDG were injected i.v. and 2D imaging (whole-body scan and at least a tomoscintigram) was started 45 min. later, using a PICKER gamma camera. We studied 14 patients (pts). All of them were operated on (mean time between FDG and surgery: 5.4 +/- 3.8 days) and staging results were correlated with post surgical histology.Results: The primary lesion took up FDG in all cases but one (FN in a 5 mm lesion). The primary NM staging of these 14 pts was negative with FDG-CDET in 7 cases (4 TN and 3 FN corresponding to an invasion of satellite lymph nodes in 2 cases and to a metastatic infracentimetric subdiaphragmatic lymph node in one case) and positive in 7 cases (7 TP corresponding to 10 foci), revealing in 4 cases a sub-diaphragmatic lymph node extension unknown prior to FDG-CDET. One pt referred for characterisation of an oesophageal lesion (failure of multiple biopsies) had an intense focus of FDG uptake in this area (TP confirmed by surgery). The overall sensitivity was 13/14 = 93% on a per patient basis and 21/25 = 84% on a per lesion basis. Specificity on a per lesion basis was 5/5 = 100%.Conclusion: These first results, obtained in an indication of FDG not frequently evaluated even with dedicated PET systems, seem very promising, the oesophageal neoplastic lesions appearing to take up FDG with a high intensity.  相似文献

Background  

Environmental exposure to lead remains a significant health problem for children. The costs of lead exposure in children are estimated to be considerably more than other childhood diseases of environmental origin. While long-term trends in blood lead levels (BLLs) among children are declining, seasonal variation persists. Cross-sectional studies have found a peak in summer months. Part of this variation may be due to increased exposure to lead paint on window sills and through increased contact with soils containing lead during the summer. The current study represents the largest published population-based study on seasonality and trends in the BLLs of children to date. In addition, the results offer a comparison of recent data on seasonality of BLLs in New York State children, to studies conducted over the past three decades.  相似文献
