Abstract:
0bjective Evaluate the clinical factors affecting the definite pathological diagnosis of solitary pulmonary odules(SPN).Methods From Jan 2000 to July 2009,390 patients(212 men,178 women,median age 57.1 years,range from 17 to 86 years)got definite pathological diagnosis of solitary pulmonary nodules in our Institute were investigated.All following clinical data were collected:age,gender,course of disease,symptoms,history and quantity of smoking,history of tumor,family history of tumor,site,diameter,calcification,spicular sign,border,lobulated,traction of pleural,vascular convergence sign,lymph nodes of mediastinum,adhesion,depression of pleural,pleural effusion.Results The surgical procedures included 20 tumor enucleation,153 wedge resection,and 217 lobectomy.There were 130 benign lesions,including hamartoma(n=33),arteriovenous istula(n=1),cyst(n=2),interstitial pneumonia(n=1),tuberculoma(n=49),lymphoproliferative(n=2),fungal ball(n=3),neurofibroma(n=1),inflammatory pseudotumor(n=27),sclerosing hemangioma(n=9),bronchiectasis(n=2).260 were malignant lesions,including Alveolar cell carcinoma(n=23),Metastatic carcinoma(n=20),Carcinoid(n=4),Squamous cell carcinoma(n=40),adenecarcinoma(n=164),Small cell carcinoma(n=9).Single factor analysis and Logistic regression analysis show that there were significant differences in age, diameter,border,calcification and depression of pleural in judgement character of SPN.In addition,there were no differences in gender,course of disease,symptoms,history and quantity of smoking,history of tumor,family history of tumor,site,spicu lar sign,lobulated,traction of pleural,vascular convergence sign,lymph nodes of mediastinum,adhesion and pleural effusion.Conclusion Age of patient,and diameter,border,calcification,pleural depression of the tumor were significant risk factors in judgment character of SPN.
