RESUMO

Objective To explore the methods and curative effect of metallic self-expanding stent in inoperable malignant gas-troduodenal obstruction. Methods The data of 15 cases with gastroduodenal obstruction including 9 cases of carcinoma of head of pancreas and 6 cases of carcinoma of stomach were analyzed retrospectively. The operative procedures of the stent implanted and the tors accepted more radiation dose because the manipulation was under the fluoroscopy in a short distance and with a full field of view. sions, the postoperative eating habit and the development turnover of disease. The main death reasons were tumor transfer and sys-tem exhaustion. Conclusion To pay close attention to the details and main points of operative procedure is the key point to implant stent successfully for malignant gastroduodenal obstruction. The determinative factor to influence the curative effect is the develop-ment turnover of tumor.

RESUMO

Objective:To evaluate the clinical efficacy of maintenance chemotherapy for patients who had local advanced non-small cell lung cancer (NSCLC) and was responsive to primary radiotherapy and chemotherapy. Methods:One hundred and twenty patients with stage ⅢA or ⅢB NSCLC received 4 cycles of chemotherapy combined with radiotherapy. The 63 patients who achieved certain remission were randomly divided into maintenance chemotherapy group(n=33) and control group(n=30). The patients in maintenance chemotherapy group (treatment group) received vinorelbine (20 mg/m2, d 1 and d 8, per 28 d a cycle) and those in control group were not given maintenance chemotherapy. The clinical efficacy, survival rate and adverse reaction of the two groups were evaluated. Results:There are a longer median time to progression(TTP) in treatment group compared with control group (8.5 month vs 5.0 month, P0.05). Conclusion:Maintenance vinorelbine-based chemotherapy prolonged the median time to progression but had no effect on survival time in patients with local advanced NSCLC who responded to induction chemotherapy.
