双部位CT引导下穿刺活检肺及其他部位共存病变

Double-site CT-guided biopsy of pulmonary and co-existent other parts of lesions

目的 探讨同时对肺及其他部位共存病变行双部位CT引导下穿刺活检的临床意义。方法 回顾性分析134例接受双部位CT引导下穿刺活检的临床疑似恶性肿瘤患者资料。依活检部位组合类型分为肺-肺、肺-淋巴结样结构、肺-骨、肺-远隔软组织4组。分析4组及肺内不同病变部位双部位活检病理的良恶性分布特点。结果 肺-肺、肺-淋巴结样结构、肺-骨、肺-远隔软组织4组中,双部位均为恶性的比率分别为44.59%（33/74）、82.35%（14/17）、78.79%（26/33）、70.00%（7/10）;肺内不同部位病变的良恶性分布差异无统计学意义（χ~2=2.22,P=0.70）。结论 对于肺及其他部位同时怀疑恶性病变的患者,CT引导下双部位穿刺活检在明确病变性质、指导临床决策等方面具有重要价值。

Objective To investigate the clinical significance of double-site CT-guided biopsy in patients who presented with both suspected pulmonary neoplasm and suspected metastases in other sites. Methods All of the 134 patients were enrolled, who were divided into four groups according to biopsy-site classes, namely lung-lung group, lung-lymph node like structure group, lung-bone group, lung-distant soft tissue group. The pathological distribution characteristics of lesions in different groups and different lung anatomy sites were retrospectively investigated. Results The percentage of both lesions Were malignant was respectively 44.59% （33/74）, 82.35% （14/17）, 78.79% （26/33）, 70.00% （7/10） in lung-lung group, lung-lymph node like structure group, lung-bone group and lung-distant soft tissue group. The pathological distri-bution characteristic of lesions in different lung anatomy sites had no statistically difference （Z2= 2.22, P= 0.70）. Conclusion For patients with both suspected pulmonary neoplasm and suspected metastases in other sites of body, double site CT-guided biopsy is useful in clinical diagnosis and decision-making process.
