With the widespread use of multi-slice spiral computed tomography(CT) and the increasing level of diagnosis and treatment,the incidence of pulmonary ground glass opacity(GGO) is increasing.The etiology of GGO is complex and the pathological types are diverse.In addition to benign lesions,GGO can be a specific type of lung adenocarcinoma or its invasive lesions.Some scholars think it is closely related to early lung adenocarcinoma.Histopathology of lung cancer is crucial for the prognosis and treatment of lung cancer.However,under normal circumstances,the pathology of the patient can be known by surgery,bronchoscopy or puncture.However,many patients may not have the pathological conditions for obtaining the pathological specimen.CT as the primary method of diagnosis of lung adenocarcinoma,lung adenocarcinoma in the new classification,based on the lung GGO CT findings to determine its ability to provide a characteristic indicator of tumor histopathology in order to help GGO diagnosis and guidance of clinical treatment.

Objective:To analyze the law of distant metastasis in patients with small lung adenocarcinoma with different CT findings, and to explore the feasibility of different preoperative examination methods for small lung adenocarcinoma with different imaging characteristics.Methods:Clinicopathological data of cT1a-cN0 lung adenocarcinoma patients admitted to the respiratory center of China-Japan Hospital from January 2017 to December 2018 were retrospectively collected. A total number of 785 patients were included, including 289 males and 496 females. SPSS 22.0 was used for statistical analysis.Results:A total number of 785 patients were included in this study, including 287 pure ground-glass nodule (GGN) patients, 111 GGN predominant patients, 221 solid predominant patients and 166 solid nodule patients. Among the included patients, 8 had distant metastasis, including 6 with bone metastasis, 1 with brain metastasis and 1 with brain and adrenal metastasis. No distant metastasis was observed in the patients with pure GGN and GGN predominant nodule, while 1 solid predominant patients had distant metastasis, and 7 patients with solid nodules had distant metastasis. The probability of distant metastasis was 0.5% for the solid predominant patients and 4.2% for the solid nodule patients. Univariate analysis results showed that CEA level ( P=0.030), the largest diameter of the lung window tumor ( P=0.003), the largest diameter of the solid component of the lung window tumor ( P<0.001), the largest area of the lung window tumor ( P=0.002), mediastinal window tumor maximum area ( P<0.001), CTR ( P<0.001), TDR ( P<0.001), and pleural indentation sign ( P=0.037) were risk factors for distant metastases. Multivariate analysis showed that CEA ( OR=1.019, 95% CI: 1.002-1.037, P=0.028) and TDR ( OR=0.000, 95% CI: 0.000-0.310, P=0.001) were independent risk factors of distant metastasis. Conclusion:For patients with pure GGN and GGN predominant nodule, preoperative examination could not be required, but for pure solid nodules, it is necessary to perform relevant preoperative examination including skull MRI before surgery to exclude distant metastasis.

Objective    To investigate the predictive value of preoperative radiological features on spread through air spaces (STAS) in stage cⅠA lung adenocarcinoma with predominant ground-glass opacity, and to provide a basis for the selection of surgical methods for these patients. Methods    The clinical data of 768 patients with stage cⅠA lung adenocarcinoma undergoing operation in our hospital from 2017 to 2018 were reviewed, and 333 early stage lung adenocarcinoma patients with predominant ground-glass opacity were selected. There were 92 males and 241 females, with an average age of 57.0±10.0 years. Statistical analysis was performed using SPSS 22.0. Results    STAS-positive patients were mostly invasive adenocarcinoma (P=0.037), and had more micropapillary component (P<0.001) and more  epidermal growth factor receptor (EGFR) gene mutations (P=0.020). There were no statistically significant differences between the STAS-positive and STAS-negative patients in other clinicopathological features. Univariate analysis showed that the maximum diameter of tumor in lung window (P=0.029), roundness (P=0.035), maximum diameter of solid tumor component in lung window (P<0.001), consolidation/tumor ratio (CTR, P<0.001), maximum area of the tumor in mediastinum window (P=0.001), tumor disappearance ratio (TDR, P<0.001), average CT value (P=0.001) and lobulation sign (P=0.038) were risk factors for STAS positive. Multivariate logistic regression analysis showed that the CTR was an independent predictor of STAS (OR=1.05, 95%CI 1.02 to 1.07, P<0.001), and the area under the receiver operating characteristic (ROC) curve was 0.71 (95%CI 0.58 to 0.85, P=0.002). When the cutoff value was 19%, the sensitivity of predicting STAS was 66.7%, and the specificity was 75.2%. Conclusion    CTR is a good radiological feature to predict the occurrence of STAS in early lung adenocarcinoma with predominant ground-glass opacity. For the stage cⅠA lung adenocarcinoma with predominant ground-glass opacity and CTR ≥19%, the possibility of STAS positive is greater, and sublobar resection needs to be carefully considered.

Objective    To investigate the mediastinal lymph node metastasis of cT1a-cN0M0 lung adenocarcinoma, so as to provide a theoretical basis for intraoperative lymph node dissection in patients with early stage lung adenocarcinoma. Methods    Clinicopathological features of lung adenocarcinoma patients who received operation in our hospital from 2017 to 2018 were collected. A total of 667 patients including 241 male and 426 female patients at age of 59 (16, 87) years were included. There were 234 patients with pure ground glass nodules, 98 patients with ground glass-predominant tumor, 199 patients with consolidation-predominant tumor and 136 patinets with solid tumor in the study. Postoperative N1 lymph node metastasis occurred in 30 patients and N2 lymph node metastasis occurred in 52 patients. Results    The result of univariate analysis showed that male (P=0.014), higher carcino-embryonic antigen levels (P<0.001), larger nodal diameter (P<0.001), larger consolidation tumor ratio (P<0.001), smaller tumor disappearance ratio (P<0.001), solid nodules (P<0.001), cavitary sign (P=0.005), lobulation sign (P=0.002), spicule sign (P=0.003), pleural indentation sign (P=0.001), bronchus sign (P=0.025) were risk factors for mediastinal lymph node metastasis. In terms of pathology, the N2 positive group had larger size of pathological tissue (P<0.001), more N1 lymph node metastasis (P<0.001), higher pathology T stage (P<0.001), more spread through air space (P=0.001), more pleural invasion (P<0.001), and more lymphovascular invasion (P<0.001). Multivariate analysis showed that lymphovascular invasion (OR=6.9, 95%CI 2.3-20.7, P=0.001), larger consolidation tumor ratio (OR=109.6, 95%CI 3.8-3 124.3, P=0.006), cavitary sign (OR=3.1, 95%CI 1.1-8.3, P=0.028) and N1 lymph node metastasis (OR=15.7, 95%CI 6.7-36.4, P<0.001) were independent risk factors for mediastinal lymph node metastasis. Conclusion    For lung adenocarcinoma, mediastinal lymph node metastasis will not occur in ground glass nodule and ground glass-predominant tumor patients. The probability of mediastinal lymph node metastasis increases with the increase of solid components and presence of cavitary sign. Therefore, different types of lymph node resection can be considered for patients with different imaging findings.

Objective To assess the accuracy of CT features of lung nodules (≤3 cm) in predicting the accuracy of the pathological subtype and degree of infiltration of adenocarcinoma. Methods We retrospectively analyzed the clinical data of 333 patients with non-cavitary pulmonary nodules diagnosed as adenocarcinoma by surgery and pathology in the China-Japan Friendship Hospital from 2011 to 2018, including 108 males and 225 females, aged 16-82 (59.57±10.16) years. The basic clinical data and CT characteristics of the patients were recorded. Results When the average CT value was ≥507 Hu, the maximum diameter of the lung window was ≥14.5 mm, and the solid component ratio was ≥5.0%, it indicated more likely the invasive adenocarcinoma (IAC). The higher the average CT value of the nodule, the larger the maximum diameter of the lung window, and the more solid components, the higher the degree of infiltration. CT morphological features (including burrs, lobes, vascular signs, bronchial signs, pleural stretch or depression signs) were more common in IAC. Among them, burrs were more common in acinar adenocarcinoma and papillary adenocarcinoma. In invasive adenocarcinoma, the higher the risk of recurrence of the pathological subtype, the greater the average CT value. When the average CT value of IAC was >−106 Hu, and the proportion of solid components was ≥70.5%, the histological subtypes were more inclined to micropapillary/solid predominant adenocarcinoma. Conclusion The evaluation of CT features of lung nodules can improve the predictive value of histopathological types of lung adeno-carcinoma, thereby optimizing clinical treatment decisions and obtaining more ideal therapeutic effects.
