Abstract:
Objective To analyze the CT features of cavitation between primary lung adenocarcinoma and squamous cell cancer.Methods The CT findings of cavity of primary lung adenocarcinoma and squamous cell carcinoma were evaluated in 57 patients,including 33 of squamous cell carcinoma and 24 of adenocarcinoma.The clinical data and CT features were analyzed retrospectively using the independent samples t-test,Pearson Chi-square test or Fisher's exact test.Results The mean age of ptients with squamous cell carcinoma was higher than that of patients with adenocarcinoma (65.57-4-9.26 vs 58.75 ± 11.12,P =0.015).Statistical differences were found in distribution of gender and smoking habit between the two kinds of carcinomas (P =0.014 and P =0.029).The T stages were also different between the two carcinomas (P=0.003).In addition,the maximum diameter of tumor (P =0.003),the maximum diameter of cavity (P =0.029) and the maximum thickness of the cavity wall (P=0.001) of squamous cell carcinoma were higher than those of adenocarcinoma.Moreover,the presence of ground-glass opacity (P =0.010),vessel passing through the cavity (P =0.001),septum inside the cavity (P＜0.001) and tumoral bronchogram (P =0.027) in adenocarcinoma were higher than those in squamous cell carcinoma.Conclusion There are significant differences between adenocarcinoma and squamous cell carcinoma in the population distribution and image features,comprehensive analysis helps the differential diagnosis.
