BACKGROUND AND PURPOSE: To compare lung injury among non-small cell lung cancer (NSCLC) patients treated with IMRT or proton therapy as revealed by 18F-FDG post-treatment uptake and to determine factors predictive for clinically symptomatic radiation pneumonitis. MATERIAL AND METHODS: For 83 patients treated with IMRT or proton therapy, planning CT and follow up 18F-FDG PET-CT were analyzed. Post-treatment PET-CT was aligned with planning CT to establish a voxel-to-voxel correspondence between PET and planning dose images...

The US FDA granted accelerated approval to pembrolizumab for microsatellite instability-high and mismatch repair deficient cancers. The response of programmed death-1 blockade in mismatch repair proficiency (pMMR) colorectal cancer is very poor, however, whether such treatment is effective in pMMR nasopharyngeal carcinoma (NPC) remains unknown. We report a case of a 51-year-old man with NPC. PET-CT scan revealed a space-occupying lesion in the left lung, and the pathologic result confirmed the occupying lesion originated from NPC...

Respiratory motion reduces both the qualitative and quantitative accuracy of PET images in oncology. This impact is more significant for quantitative applications based on kinetic modeling, where dynamic acquisitions are associated with limited statistics due to the necessity of enhanced temporal resolution. The aim of this study is to address these drawbacks by combining within a unique reconstruction algorithm in dynamic PET imaging, a respiratory motion correction approach, as well as a temporal regularization...

BACKGROUND: The value of maximum standard uptake value (SUVmax) was overlooked in current studies comparing stereotactic body radiotherapy (SBRT) versus surgery for stage I non-small cell lung cancer (NSCLC). Herein, we aimed to compare the 3-year outcomes based on patients for whom SUVmax were available, and to explore the role of SUVmax in clinical decision-making. METHODS: From January 2010 to June 2016, data of eligible patients were collected. Patient variables and clinical outcomes were compared in both unmatched and matched groups using propensity score matching (PSM)...

A 65-year-old man was diagnosed with granulomatosis with polyangiitis (GPA) at the age of 47, when cytoplasmic anti-neutrophil cytoplasmic antibody (C-ANCA) serology was positive, and he had multiple nodular shadows in both lungs. He had been treated with prednisolone, cyclophosphamide (CPA) and plasma exchange. At the age of 64, a nodular shadow was newly detected in the right lower lung field and serum tumour marker increased. Subsequent positron emission tomography/computed tomography scan demonstrated accumulations of fluorodexyglucose (FDG) in the same area, mediastinum lymph nodes, thoracic wall, right iliac bone, and right retroperitoneum...

The use of endobronchial ultrasound trans-bronchial needle aspiration (EBUS-TBNA) as the initial diagnostic and staging procedure in patients with suspected, non-metastatic lung cancer has gained substantial support, and is now recommended by numerous guidelines. Whereas considerable attention has been pointed to the reductions in costs achieved by EBUS-TBNA, that has not been the case for some of its more significant benefits, namely the reduction of the diagnostic work-up time and its ability to accurately assess and restage lymph nodes, which were previously stated incorrectly by CT or PET scan...

Background: The prediction of local recurrence (LR) of stage I non-small cell lung cancer (NSCLC) after definitive stereotactic body radiotherapy (SBRT) remains elusive. The purpose of this study was to assess whether quantitative imaging features on pre-treatment computed tomography (CT) can predict LR beyond 18 (18F) fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT maximum standard uptake value (SUVmax). Methods: This retrospective study evaluated 36 patients with 37 stage I NSCLC who had local tumor control (LC; n=19) and (LR; n=18)...

BACKGROUND AND PURPOSE: CT ventilation imaging (CTVI) derived from four dimensional CT (4DCT) has shown only moderate spatial accuracy in humans due to 4DCT image artefacts. Here we assess the accuracy of an improved CTVI using high quality exhale/inhale breath-hold CT (BHCT). MATERIALS AND METHODS: Eighteen lung cancer patients underwent exhale/inhale BHCT, 4DCT and Galligas PET ventilation scans in a single imaging session. For each BHCT and 4DCT scan, we performed deformable image registration (DIR) between the inhale and exhale phase images to quantify ventilation using three published metrics: (i) breathing induced lung density change, CTVIDIR-HU (ii) breathing induced volume change CTVIDIR-Jac and (iii) the regional air-tissue product, CTVIHU Spatial accuracy was reported as the voxel-wise Spearman correlation r between CTVI and Galligas PET...

A patient presenting with concomitant epidermal growth factor receptor (EGFR) mutation and anaplastic lymphoma kinase (ALK) translocation is very rare. We report a non-small cell lung cancer (NSCLC) patient with concomitant EGFR (exon 19-del) mutation and ALK rearrangement. The positron emission tomography-computed tomography (PET-CT) scan revealed a highly metabolic mass lesion in the left lower lobe, measured 5.0 cm in the largest dimension in the S6 segment. Transbronchial lung biopsy (TBLB) showed the pathological diagnosis of invasive adenocarcinoma...

Adenocarcinoma (AC) is the most common type of primary pulmonary malignancy. Lung carcinoid, however, is a rare neuroendocrine tumor. Their coexistence is extremely uncommon. We report the unique case of synchronous advanced lung AC of the right upper lobe (stage IIIB) and typical endobronchial carcinoid tumor in the contralateral lower lobe in a 49-year-old white female who had never smoked. PET-computed tomography scan revealed a fluorine-18-fluorodeoxyglucose-avid AC lesion, whereas the carcinoid tumor was fluorine-18-fluorodeoxyglucose occult...

More than 80% of lung cancer is non-small cell lung cancer (NSCLC), and the epidermal growth factor receptor (EGFR)-mediated signaling pathway is closely related to the occurrence and development of NSCLC. Small molecule EGFR-tyrosine kinase inhibitors (EGFR-TKI) targeting EGFR have been used in the clinical treatment of NSCLC, and positron emission tomography/computed tomgraphy (PET/CT) imaging can noninvasively monitor the expression and mutation status of EGFR in patients with NSCLC. 18F-FDG PET/CT imaging has predictive value for the activation of EGFR mutation and EGFR-TKI treatment efficacy, and in vivo can be directly observed drugs and systemic tumor targeting EGFR combined with the specific circumstances, by PET/CT imaging before and after treatment, to achieve dynamic monitoring, guide the therapy before treatment and treatment of sensitive population screening process, to achieve NSCLC EGFR-TKI precise treatment is essential...
