Mimics of lung cancer.

[Mimics of lung cancer]. Radiologe. 2018 Dec 14;: Authors: Eisenhuber E, Schaefer-Prokop C, Mostbeck G Abstract Lung cancer is a histologically, immunologically and therefore morphologically and functionally very heterogeneous group of neoplasms with the highest cancer mortality worldwide. Therefore, the range of diseases mimicking lung cancer is also very broad and includes congenital, infectious and inflammatory changes as well as other benign space-occupying lesions and other primary and secondary pulmonary neoplasms. The difficulty in radiology lies in the ability to diagnose lung cancer with a high degree of certainty. This must take the limits of the specific diagnosis, knowledge of the classical pitfalls and rare entities that can imitate lung cancer into consideration. Narrowing the differential diagnosis requires close interdisciplinary cooperation and consideration of the patient's clinical and medical history. An accurate analysis of the computed tomography (CT) pattern and distribution of the lesions as well as consideration of additional changes and involvement of other organ systems can be the key to the diagnosis. The use of fluorodeoxyglucose positron-emission tomography CT (FDG-PET-CT) is helpful only in a few mimics of lung cancer. The article describes clinical and radiological findings of mimics of lung cancer also pointing out the limitations of CT and PET-CT for the diagnosis. PMID: 30552483 [PubMed - as supplied by p...

Systemic air embolism developed after CT ‐guided TTNB, leading to ST‐elevation, myocardial infarction and acute ischemic stroke. The patient recovered completely without sequelae and was diagnosed with adenocarcinoma harboring activatingEGFR mutation. Treatment with gefitinib showed a response. Air embolism is a rare, fatal complication of computed tomography (CT) ‐guided transthoracic needle biopsy (TTNB) of the lung. Here, we report a patient who developed an air embolism after CT‐guided TTNB, which led to ST‐elevation myocardial infarction and acute cerebral ischemia. The patient recovered completely without c...

Conclusion: A single-tissue reversible model can be used to quantify tumor uptake of the PD-L1 PET tracer 18F-BMS-986192. SUV at 60 min after injection, normalized for body weight, is an accurate simplified parameter for uptake assessment of baseline studies. To assess its predictive value for response evaluation during programmed cell death protein 1 or PD-L1 immune checkpoint inhibition, further validation of SUV against VT based on an image-derived input function is recommended.

an Tang Purpose: The current study aims to explore the barriers for middle-aged Chinese to learn about and uptake low-dose computed tomography (LDCT) lung cancer screening. Methods: Data were collected via an online survey in December 2019. Final valid sample included 640 respondents, aged 40–60 years old, from 21 provinces of China. We performed multiple linear regressions to test the potential barriers to LDCT scan. Findings: Cost concerns, distrust in doctors, fears of disease, lack of knowledge, and optimistic bias are negatively associated with the intention to learn about and uptake LDCT scan. Implicati...

Abstract BACKGROUND: Postoperative severe respiratory adverse events (SRAEs) are the major cause of perioperative morbidity in patients after thoracic surgery. In particular, SRAEs often occur in lung cancer patients concomitant with chronic inflammatory lung diseases (CILDs) such as interstitial lung disease, emphysema, infectious disease, and asthma. We aimed to clarify whether the measurement of the maximum of standardized uptake value in the noncancerous lung area (NCA-SUVmax) and CILDs on high-resolution computed tomography were useful for predicting the risk of SRAEs. METHODS: A total of 984 patients wi...

Conclusion: The current meta-analysis showed a moderate sensitivity and specificity of18F FDG PET or PET/CT for the prediction of OLNM in NSCLC patients. The DOR was low and the likelihood ratio scatter-gram indicated that18F FDG PET or PET/CT might not be useful for the prediction of OLNM in NSCLC patients and not for its exclusion.Oncology

Abstract OBJECTIVE: The purpose of the current study was to investigate the diagnostic performance of 18F fluorodeoxyglucose (FDG) positron emission tomography (PET) or positron emission tomography/computed tomography (PET/CT) for the prediction of occult lymph node metastasis (OLNM) in non-small cell lung cancer (NSCLC) patients through a systematic review and meta-analysis. METHODS: The PubMed, Cochrane, and EMBASE database, from the earliest available date of indexing through March 31, 2020, were searched for studies evaluating the diagnostic performance of preoperative 18F FDG PET or PET/CT for the predic...
