Prognostic Classification of Multiple Primary Lung Cancers Based on a Ground-Glass Opacity Component

Publication date: February 2020Source: The Annals of Thoracic Surgery, Volume 109, Issue 2Author(s): Aritoshi Hattori, Kazuya Takamochi, Shiaki Oh, Kenji SuzukiBackgroundWe evaluated the prognostic impact of the presence of a ground-glass opacity (GGO) component on thin-section computed tomography for the refined clinical T classification of multiple primary lung cancers.MethodsWe reviewed 272 surgically resected, clinically node-negative multiple lung cancers. Dominant tumors were classified into 2 groups based on the presence of a GGO component; that is, a GGO tumor (consolidation tumor ratio, 0 to

CONCLUSION: The authors report an unusual case of ruptured jejunal GIST with hemoperitoneum mimicking ovarian carcinoma. Therefore, GIST, in addition to ovarian cancer, should be considered in patients with an increased serum level of CA-125 and an abdominopelvic mass. PMID: 32055272 [PubMed]

Preoperative SUVmax of primary lesions is a predictor of pathological nodal metastases in peripheral cN0 NSCLC with tumor size  ≤2 cm. Primary tumor SUVmax is associated with key clinicopathological features and prognosis of patients with peripheral cN0 NSCLC with tumor size ≤2 cm. AbstractObjectiveIn this cohort study, we determined the clinical value of the maximum standardized uptake value (SUVmax) of primary tumors in non ‐small cell lung cancer (NSCLC).Study DesignA retrospective review of NSCLC patients was performed from January 2011 to December 2017. Peripheral cN0 NSCLC patients with tu...

ConclusionPatients with metastatic disease who experience a relatively long survival may be prone to undergo disproportionate recurrent CT imaging. The non-negligible CT radiation-induced cancer risk and mortality should be taken into account in these patients, while the effect of cumulatively administered CT contrast agents on kidney function requires further investigation.

AbstractObjectiveTo evaluate the value of Bayesian penalized likelihood (BPL) reconstruction for improving lesion conspicuity of malignant lung tumors on18F-fluoro-2-deoxy-d-glucose (FDG) positron emission tomography computed tomography (PET/CT) as compared with the ordered subset expectation maximization (OSEM) reconstruction incorporating time-of-flight (TOF) model and point-spread-function (PSF) correction.MethodsTwenty-nine patients with primary or metastatic lung cancers who underwent18F-FDG PET/CT were retrospectively studied. PET images were reconstructed with OSEM  + TOF, OSEM + TOF&thin...

AbstractThe aim of the study was to evaluate the ability to detect extra-cardiac foci by means of whole-body18F-fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) in patients with definite endocarditis (IE) according to the modified Duke criteria and investigate the clinical impact of the findings. From January 2011 to December 2015 we included 178 patients (mean age 66  ± 14 years, 25% female) with IE in this multicentre study. FDG-PET/CT was part of the work-up for extra-cardiac foci in the including hospitals and was performed at a median of 9 days (IQR 10) af...

AbstractObjectives(1) To assess the methodological quality of radiomics studies investigating histological subtypes, therapy response, and survival in patients with renal cell carcinoma (RCC) and (2) to determine the risk of bias in these radiomics studies.MethodsIn this systematic review, literature published since 2000 on radiomics in RCC was included and assessed for methodological quality using the Radiomics Quality Score. The risk of bias was assessed using the Quality Assessment of Diagnostic Accuracy Studies tool and a meta-analysis of radiomics studies focusing on differentiating between angiomyolipoma without visi...

ConclusionsCystoscopy-guided placement of hydrogel markers is both safe and feasible for muscle-invasive bladder tumors. Adequate performance for radiation purposes throughout the whole course (implantation, delineation, and positional verification) was 46.7% of all implanted markers, leaving room for improvement.

The epidemic of increasing fatty liver disease and liver cancer worldwide, and especially in Western society, has given new importance to non-invasive liver imaging. Contrast-enhanced ultrasound (CEUS) using microbubble contrast agents provides unique advantages over computed tomography (CT) and magnetic resonance imaging (MRI), the currently established methods. CEUS provides determination of malignancy and allows excellent differential diagnosis of a focal liver mass, based on arterial phase enhancement patterns and assessment of the timing and intensity of washout.
