Abstract:
Objective To analyze the CT features of visceral pleural invasion of peripheral non-small cell lung cancer with the largest diameter less than or equal to 3 cm to improve the diagnostic accuracy.Methods The CT features of 249 patients with peripheral non-small cell lung cancer with the largest diameter less than or equal to 3 cm were analyzed retrospectively.Multivariate Logistic regression was performed to analyze the independent risk factors of the visceral pleural invasion.Results Visceral pleural invasion was observed in 61/249 of the cases.Gender,the largest diameter,type,spiculated sign,lobulated sign,DLP and relationship of nodule and visceral pleura between the two groups were significantly different (P＜0.05).Multivariate Logistic regression analysis showed that the largest diameter and spiculated sign of nodules were independent risk factors for visceral pleural invasion.Visceral pleural invasion was uncommon in TypeⅠ.The probability of the visceral pleural invasion in typeⅡ,typeⅢand typeⅣ was 0.023 times (95% CI:0.006-0.093),0.225 times (95% CI:0.078-0.648)and 0.645 times (95% CI:0.261-2.300)as much as that of type Ⅴ,respectively.Visceral pleural invasion was more likely to occur in Type V than other types (P＜0.05).Conclusion The largest diameter and spiculated sign are independent predictors for visceral pleural invasion in non-small cell lung cancer with the largest diameter less than or equal to 3 cm.Nodules closely adjacent to the pleura are more likely to invade the visceral pleural.
