Abstract:
Objective To study the relativity between imageology and pathology during lung cancer,and estimate whether the lung cancer is preinvasive lesions,which can support evidences for the operation methods.Methods Clinical data of 624 patients who were diagnosed as lung adenocarcinoma and had solitary pulmonary nodule(diameter≤3 cm) were collected,all of them were scanned by thin layer CT scan(1 mm).The correlation between imageology and pathology data were analyzed.Results In 125 cases of GGO,the ratio of invasive lesions were 0 (0/72),6.1％ (3/49) and 100％ (4/4) in stage T1a,T1b and T1c respectively.In 285 cases of mGGO,if solid component was less than 0.5 cm,the ratio of invasive lesions were 1.7％ (1/58),6.9％ (2/29) and 50.0％ (2/4) in stage T~,T1b and Tic;but the ratio of invasive lesions were 81.3％ (13/16),94.1％ (96/102) and 97.4％ (74/76) respectively when the solid component was more than 0.5 cm.In 214 cases with solid nodules,the ratio of invasive lesions were 87.1％ (27/31),98.8％ (84/85) and 99.0％ (97/98) in stage T1 a,T1b and T1c.Conclusion The ratio of invasive lesions and solid component increased gradually along with the growing of tumor diameter in stage T1 lung cancer.CT imaging was highly correlated with the pathology diagnosis of preinvasive lesions and invasive lesions,which can be used as the guidance for operation methods.
