印度代购科普：肺癌检查项目有哪些？

　　1.X线查看经过X线查看能够了解肺癌的部位和巨细，或许看到因为支气管阻塞引起的局部肺气肿、肺不张或病灶附近部位的浸润性病变或肺部炎变。

1. X-ray viewing Through X-ray viewing can understand the location and size of lung cancer, may see because of bronchial obstruction caused by local emphysema, atelectasis or lesions near the site of infiltration or pulmonary inflammatory changes.

　　2.支气管镜查看经过支气管镜可直接窥察支气管内膜及管腔的病变状况。可采纳肿瘤安排供病理查看，或吸取支气管分泌物作细胞学查看，以明确确诊和断定安排学类型。

　　3.细胞学查看痰细胞学查看是肺癌普查和确诊的一种简洁有用的办法，原发性肺癌患者大都在痰液中可找到脱落的癌细胞。中心型肺癌痰细胞学查看的阳性率可达70%～90%，周围型肺癌痰检的阳性率则仅约50%。

　　4.剖胸探查术肺部肿块经多种查看和短期确诊性医治仍未能明确病变性质，肺癌的或许性又不能除外者，应作剖胸探查术。这样可避免延误病况致使肺癌患者失掉早期医治的时机。

　　5.ECT查看ECT骨显像能够较早地发现骨转移灶。X线片与骨显像都有阳性发现，如病灶部成骨反响静止，代谢不活泼，则骨显像为阴性，X线片为阳性，二者互补，能够提高确诊率。需求留意的是ECT骨显像确诊肺癌骨转移的假阳性率可达20%～30%，因而ECT骨显像阳性者需求作阳性区域骨的MRI扫描。

　　6.纵隔镜查看纵隔镜查看首要用于伴有纵隔淋巴结转移，不适合于外科手术医治，而其他办法又不能取得病理确诊的患者。纵隔镜查看需在全麻下进行。在胸骨上凹部做横切断，钝性分离颈前软安排抵达气管前间隙，钝性游离出气管前通道，置入观察镜缓慢经过无名动脉之后方，观察气管旁、气管支气管角及隆突劣等部位的肿大淋巴结，用特制活检钳解剖剥离取得淋巴结安排送病理学查看。原发性支气管肺癌的确诊依据包括：症状、体征、印象学表现以及痰癌细胞查看。

6. Mediastinoscopic examination Mediastinoscopic examination is mainly used for patients with mediastinal lymph node metastasis, which is not suitable for surgical treatment, and other methods cannot obtain pathological diagnosis. Mediastinoscopy should be performed under general anaesthesia. Do cross cut on the sternal notch, blunt separation soft arrange clearance before arrived in trachea, anterior portion blunt channel before free out of the trachea, into above-mentioned slowly after anonymous artery, observe the trachea, bronchi Angle and intumescent lymph node of the promontory inferior positions, with special biopsy forceps anatomic dissection lymph node arrangement send pathology view. The diagnostic criteria for primary bronchial lung cancer include symptoms, signs, impression, and sputum cancer.
