The clinical analysis of 146 cases of solitary pulmonary nodules / 重庆医学

ABSTRACT

Objective To study the relationship between the clinical imaging manifestations and the judgement of benign and malignant of solitary pulmonary nodules (SPN) .Methods A retrospective analysis of 146 patients with SPN which confirmed by pathological diagnosis .According to SPN diameter all SPN were divided into three groups ,the number of SPN which diameter smal-ler than 0 .8 cm were 16 case ,> 0 .8 - 1 .5 cm were 41 cases ,> 1 .5 - 3 .0 cm were 89 cases .Collect patients′ age ,sex ,smoking his-tory ,clinical symptoms and imaging data ,and analyze its relationship with pathological results .Results All the 146 patients were pathological diagnosis ,benign in 52 cases (35 .6% ) ,malignant in 94 cases (64 .4% ) .As the diameter increases ,the malignant rate increased .There was statistical significance in benign and malignant lesions with smoking history and clinical symptoms (P< 0 . 05) .Whether SPN boundary is clear ,have lobulation ,burr ,pleural indentation syndrome and vessel convergence in benign and ma-lignant lesions were statistically significant (P< 0 .05) .Conclusion The feature size and imaging performance of SPN has important reference value for the judgement of benign and malignant .The positive intervention to SPN have great significance on improve sur -vival rate of lung cancer .
