摘要

目的：探讨浸润性肺腺癌（IACL）的 CT 成像特征：探讨浸润性肺腺癌（IACL）的 CT 影像特征：CT 显示肺部结节并经病理证实为 IACL 的 290 例患者。将 290 例病例分为高危组（115 例）和低危组（175 例），对影像学数据进行回顾性分析。采用三维（3D）和放大技术显示结节，并对其进行观察和测量。收集结节的密度、大小和位置数据，并进行 T 检验或卡方检验：结果：在 290 例 IACL 患者中，所有病灶均表现为结节，伴有分叶状和血管/索状阴影，三维和放大图像可清晰显示这些阴影。其中 153 个（52.8%）为实性结节，43 个（14.8%）为亚实性结节，29 个（10.0%）为磨玻璃结节，65 个（22.4%）为伴有空腔或空泡的结节。结节小于 1 厘米的有 19 例（6.5%），1-2 厘米的有 180 例（62.1%），2-3 厘米的有 91 例（31.4%）。结节呈球形生长的有 109 例（37.6%），非球形生长的有 181 例（62.4%）。61例（21.1%）结节伴有等于或少于四个血管/脊索影，229例（78.9%）结节伴有四个以上血管/脊索影。144例（79.6%）结节的生长角度为45°或135°，矢状面生长角度在左右两侧有明显差异（P=0.032）：结论：放大和三维技术可清晰显示IACL的特征，即分叶结节伴血管/索影，实性结节最多。有空腔或空泡且小于 2 厘米的结节多出现在低风险组。生长角度可反映 IAC 的生长模式和病理特征。

Three-dimensional and magnified CT images of displaying the imaging features of invasive adenocarcinoma of lung.

Objective: To discuss CT imaging characteristics of invasive adenocarcinoma of lung(IACL).

Methods: CT revealed the nodule of lung which pathology confirmed as IACL of 290 cases. Imaging data were retrospectively analyzed by dividing into high-risk group of 115 cases and low-risk group of 175. Three dimensional (3D) and magnified technology were used to show the nodules, which were observed and measured. Data of density, size and location of nodule were collected, and T-test or Chi-square test were performed.

Results: In 290 cases with IACL, all lesions appeared as nodule with lobulated and vascular/cord shadows, which can be clearly shown by the 3D and magnified images. 153 (52.8%) were solid nodule, 43 (14.8%) sub-solid, 29 (10.0%) ground glass and 65 (22.4%) nodule with cavity or vacuole. Nodules less than 1 cm were in 19 cases (6.5%), 1-2 cm in 180 (62.1%) and 2-3 cm in 91(31.4%).Nodules with spherical growth were in 109 cases (37.6%), non spherical growth in 181 (62.4%). Nodules with equal or less than four vascular/cord shadows were in 61 cases (21.1%) and more than four in 229 (78.9%). There are significant differences between high-risk and low-risk groups in density, size, and vascular/cord shadows (P < 0.05), no significant difference in nodule location and growth direction (P > 0.05).The growth angle were shown to be 45 ° or 135 ° in 144 (79.6%)cases, there was significant difference in the growth angle of sagittal plane between on the right and left (P = 0.032).

Conclusion: Magnified and 3D technology can clearly show the features of IACL, which are lobulated nodule with vascular/cord shadows, and the most are solid nodule. Nodule with cavity or vacuole and less than 2 cm more appear in low-risk group. Growth angle may reflect the growth pattern of IAC and the pathological characteristics.

期刊介绍： World Journal of Surgical Oncology publishes articles related to surgical oncology and its allied subjects, such as epidemiology, cancer research, biomarkers, prevention, pathology, radiology, cancer treatment, clinical trials, multimodality treatment and molecular biology. Emphasis is placed on original research articles. The journal also publishes significant clinical case reports, as well as balanced and timely reviews on selected topics. Oncology is a multidisciplinary super-speciality of which surgical oncology forms an integral component, especially with solid tumors. Surgical oncologists around the world are involved in research extending from detecting the mechanisms underlying the causation of cancer, to its treatment and prevention. The role of a surgical oncologist extends across the whole continuum of care. With continued developments in diagnosis and treatment, the role of a surgical oncologist is ever-changing. Hence, World Journal of Surgical Oncology aims to keep readers abreast with latest developments that will ultimately influence the work of surgical oncologists.
