    Tumour cell PD-L1 expression is prognostic in patients with malignant pleural effusion: the impact of C-reactive protein and immune-checkpoint inhibition

    No full text
    Malignant pleural effusion (MPE) confers dismal prognosis and has limited treatment options. While immune-checkpoint inhibition (ICI) proved clinical efficacy in a variety of malignancies, data on the prognostic role of PD-L1 in MPE is scarce. We retrospectively studied PD-L1 tumour proportion score and Ki-67 index in pleural biopsies or cytologies from 123 patients (69 lung cancer, 25 mesothelioma, and 29 extrathoracic primary malignancies). Additionally, the impact of C-reactive protein (CRP) and platelet count was also analysed. Median overall survival (OS) after MPE diagnosis was 9 months. Patients with PD-L1 positive tumours (=1\%) had significantly shorter OS than patients with negative PD-L1 status (p = 0.031). CRP and Ki-67 index were also prognostic and remained independent prognosticators after multivariate analysis. Interestingly, Ki-67 index and CRP influenced the prognostic power of PD-L1. Finally, patients receiving ICI tended to have a longer median OS and CRP - but not PD-L1 - was a significant prognosticator in this subgroup. In summary, histological and circulating biomarkers should also be taken into account as potential biomarkers in ICI therapy and they may have an impact on the prognostic power of PD-L1. Our findings might help personalizing immune-checkpoint inhibition for patients with MPE and warrant further prospective validation

    Impact of apical foreshortening on deformation measurements: a report from the EACVI-ASE Strain Standardization Task Force

    No full text
    Aims Foreshortening of apical views is a common problem in echocardiography. It results in an abnormally thick false apex and a shortened left ventricular (LV) long axis. We sought to evaluate the impact of foreshortened (FS) on LV ejection fraction (LVEF) and layer-specific 2D speckle tracking based segmental (S) and global (G) longitudinal strain (LS) measurements. Methods and results We examined 72 participants using a GE Vivid E9 system. FS apical views were collected from an imaging window one rib-space higher than the optimal images. Ejection fraction as well as layer-specific GLS and SLS measurements were analysed by GE EchoPAC v201 and TomTec Image Arena 4.6 and compared between optimal and FS images. On average, LV long axis was 10\% shorter in FS images than in optimal images. FS induced a relative change in LVEF of 3.3\% and 6.9\% for GE and TomTec, respectively (both, P < 0.001). Endocardial GLS was 9.0\% higher with GE and 23.2\% with TomTec (P < 0.001). Midwall GLS measurements were less affected (7.8\% for GE and 14.1\% for TomTec, respectively, both P< 0.001). Segmental strain analysis revealed that the mid-ventricular and apical segments were more affected by foreshortening, and endocardial measurements were more affected than midwall. Conclusion Optimal image geometry is crucial for accurate LV function assessment. Foreshorhening of apical views has a substantial impact on longitudinal strain measurements, predominantly in the apex and in the endocardial layer. Our data suggest that measuring midwall strain might therefore be the more robust approach for clinical routine use

    The Correlation of the SLAP II Lesion Findings Between Physical Examination, Magnetic Resonance Imaging, and Arthroscopic Surgery

    Objectives The aim of this study is to demonstrate the importance of clinical diagnosis by comparing with preoperative physical examination and magnetic resonance imaging (MRI) images in patients who were arthroscopically diagnosed as having Superior Labrum Anterior-Posterior (SLAP) II lesions. Materials and Methods 134 patients, arthroscopically diagnosed as SLAP II, established the study group, and 200 patients who underwent shoulder arthroscopy for the other pathologies established the control group. Preoperative clinical examination of the patients, MRI findings, and the arthroscopic findings of the patients were recorded. Results Out of the patients diagnosed with a SLAP II lesion, 107 (79.9) of those had an MRI finding while only 60 (30\%) of the control group had it. The O'Brien test results of the patients diagnosed with SLAP were positive in 111 (82.8\%) while those diagnosed with intact superior labrum were positive in 132 (66\%). Of the 134 patients with a SLAP II lesion, 89 (66.4\%) had both O'Brien test positiveness and MRI finding, and 129 (96\%) had at least one positive result of the O'Brien test or MRI examination Conclusion The O'Brien test and MRI examination are not capable enough to indicate a SLAP lesion one by one, because of the low sensitivity and specificity. But, combining the test with MRI findings provides more trustable information about the superior labrum
