چکیده
【摘要】 背景与目的 放射性I 粒子组织内植入治疗,具有对肿瘤组织高度适形,低剂量长时间照射的特点。 本研究通过测定I粒子植入治疗前后肺癌患者血清CEA、CA125、NSE、CYFRA21-1等肿瘤标志物水平,观察 I粒子 植入前后肿瘤标志物的变化,观察肿瘤治疗疗效分级与肿瘤标志物水平的关系。方法 用放射免疫方法测定I粒子植 入治疗肺癌患者前后血清中CEA、CA125、NSE、CYFRA21-1的浓度。结果 I粒子植入1月后,肺癌患者血清中CEA、 CA125、NSE、CYFRA21-1等肿瘤标志物与植入前比较即出现明显变化(P<0.01)。 I粒子植入后1个月、3个月、6个月 上述肿瘤标志物水平各组间比较无明显差异。结论 I粒子植入治疗肺癌能够有效的降低多项肿瘤标志物的水平,不 同的疗效分级的肿瘤标志物水平明显不同。 【关键词】 肺肿瘤; I粒子;CT;肿瘤标志物 【中图分类号】 R734.2 DOI:10.3779/j.issn.1009-3419.2009.02.08

Magnetic nanoparticles have been highly regarded because of their unique properties, such as hyperthermia, medicine control release, and diagnostic applications. The main aim of the current paper is to offer a new system for the modification of Fe3O4 (SPIONs) superparamagnetic nanoparticles physically and chemically with polymers through physical retention. These modified nanoparticles have bee...
متن کاملAnalysis of the Results of Pulmonary Resection by Minimally Invasive Thoracoscopy for the Surgical Treatment of Lung Cancer
Introduction: Lung cancer is the disease of modern era, and the rate of lung cancer mortality is three times as high as that for prostate cancer and twice as high as the rate for breast cancer. We aimed to analyze the results of pulmonary resection in patients with NSCLC by minimally invasive thoracoscopy. Materials and Methods: We studied 10 patients with NSCLC scheduled for surgical resectio...

Summary: Adenosine through adenosine receptor have a crucial role in biology of lung cancer. Recent study indicated adenosine receptors have a crucial role in various aspect of lung cancer from cell growth and metastasis to modulation of apoptosis and it could be considered as a potential candidate for treatment of the lung cancer.
متن کاملبررسی فراوانی عفونت سل نهفته در بیماران مبتلا به سرطان ریه و مقایسه آن با افراد سالم
Background: Lung cancer is the fifth most common cancer in Iran, with 10.5 and 1.5 per 100,000 in males and females, respectively. The study of latent tuberculosis infection (LTBi) in patients with lung cancer is significant due to the possibility of its activation during chemotherapy and increased mortality. Therefore, the aim of this study was to compare the prevalence of LTBi in patients wit...
متن کاملDetection of lung cancer using CT images based on novel PSO clustering
Lung cancer is one of the most dangerous diseases that cause a large number of deaths. Early detection and analysis can be very helpful for successful treatment. Image segmentation plays a key role in the early detection and diagnosis of lung cancer. K-means algorithm and classic PSO clustering are the most common methods for segmentation that have poor outputs. In t...
