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...
