Which Window Setting Is Best for Estimating Pathologic Invasive Size and Invasiveness?

Publication date: August 2019Source: The Annals of Thoracic Surgery, Volume 108, Issue 2Author(s): Joji Samejima, Hiroyuki Ito, Haruhiko Nakayama, Takuya Nagashima, Junichiro Osawa, Kenji Inafuku, Masaki Suzuki, Tomoyuki Yokose, Kouzo Yamada, Munetaka MasudaBackgroundIn the Eighth Edition of the Tumor Node Metastasis Classification System for Lung Cancer, the definitions of the clinical T and pathologic T descriptors have changed. Little has been reported on comparisons between the consolidation diameter in the lung window setting and the tumor diameter in the mediastinal window setting with respect to the correlations with pathologic invasive size (IS) and invasiveness. The present study was conducted to clarify which window setting was better for preoperatively estimating IS and invasiveness.MethodsWe retrospectively reviewed 1,167 consecutive patients with lung adenocarcinomas measuring 3 cm or less in diameter. We measured three high-resolution computed tomography variables and examined correlations of IS with these variables, factors predictive of an IS of 5 mm or less, and other variables related to invasiveness.ResultsOn receiver operating characteristic curve analysis, the tumor diameter in the mediastinal window setting more strongly predicted IS than did the consolidation diameter in the lung window setting (p

Purpose: A common diagnostic dilemma in the assessment of small pulmonary nodules on computed tomography (CT) is in distinguishing benign intrapulmonary lymph nodes (IPLNs) from small primary pulmonary malignancies. Several CT features have been described of IPLNs, including attachment to a pleural surface. We had observed that IPLNs were often connected to a pulmonary vein and sought to evaluate the utility of this sign in discriminating IPLNs from lung adenocarcinomas. The frequency of other previously described CT signs of IPLNs was also compared with lung adenocarcinomas. Materials and Methods: We retrospectively ...

We report a rare case of pulmonary IVLBCL accompanying lung cancer and interstitial lesions. A 73-year-old man with a history of pneumonia underwent a follow-up examination. Computed tomography revealed diffuse, bilateral ground-glass opacities (GGO) with a partial solid mass. Histologically, the mass consisted of adenocarcinoma. However, two other types of interstitial lesions were scattered throughout the resected lung: 1) peribronchovascular thickening with the aggregation of macrophages and anthracosis, and 2) alveolar septal thickening in the centrilobular area with atypical CD20-positive large cells in the capillarie...

The maximum standardized uptake value (SUVmax) on positron emission tomography with [18  F] fluorodeoxyglucose (18 F-FDG PET) is a promising modality for predicting the prognosis and invasiveness of lung adenocarcinoma. [1,2] Especially in cases where tumors had pure-solid appearances on thin-section CT scans, the SUVmax on PET reflected the levels of tumor invasiveness and had a g reat effect on the prognoses. [3] The SUVmax has been shown to be associated with histology in lung cancer. The low SUVmax levels correlated well with lepidic predominance among clinical stage IA radiologic pure-solid lung adenocarcinoma patients.

Ground glass nodule (GGN) is defined as a hazy increased opacity of the lung, with preservation of the bronchial and vascular margins, and the diameter is less than 3  cm (1). With the wide spread of computed tomography (CT) screening, more and more lung nodules with a ground glass opacity(GGO) component have been identified (2–4). And we will meet some GGN cases more than 3 cm occasionally. To our knowledge, few previous studies as of yet had focused on th e GGO exceeding 3 cm. Our study dedicatedly included GGO more than 3 cm, and we named it ground glass mass (GGM)>3  cm firstly.

ConclusionSurgical treatment should be considered for pancreatic metastasis from lung cancer if the disease is localized and the patient’s condition is good. Additionally, combined therapy, including surgical resection, may be effective for repeated recurrence.

Conclusion :18F-FDG PET/CT metabolic parameters combined with clinicopathological data demonstrated moderate diagnostic efficacy in predicting EGFR mutation status and were associated with prognosis in mutant and wild-type EGFR non-small-cell lung cancer, thus providing a reference for individualized targeted molecular therapy.

Lung cancer is the leading cause of cancer-related death and third most common cancer in Japan [1]. Lung adenocarcinoma is the most common histological type of lung cancer [2]. Adenocarcinomas shows diversity across both the radiologic and pathologic spectrums. Additionally, the internal structure of adenocarcinomas is heterogeneous. Radiologically, adenocarcinoma often consists of various ratios of ground-glass opacity (GGO) and solid components. GGO is defined as an opacity that does not obscure the underlying structures or vasculature on high-resolution computed tomography (CT) [3], whereas solid components are defined ...
