Fibrous intimal thickening at implantation is a determinant risk factor for the functional and morphologic outcome of cadaveric renal allografts at 1 1/2 years.

Recently, well performing diagnostic criteria for analgesic nephropathy in end-stage renal failure (ESRF) patients were defined by the demonstration of a bilateral decrease in renal volume combined with either bumpy contours or papillary calcifications. In this study, the diagnostic value of computed tomography (CT) scan was compared to the previously used renal imaging techniques (sonography and conventional tomography). In a first study, a cohort of 40 analgesic abusers (defined as daily use of analgesic mixtures during at least 5 years) and 40 controls, all ESRF patients without a clear renal diagnosis, were investigated with sonography, tomography and CT scan without injection of iodinated contrast material, to search for the imaging signs of analgesic nephropathy. Using CT scan, sonography and tomography, renal size could be evaluated with comparable results while CT scan was superior in the detection of papillary calcifications (sensitivity 87%, specificity 97%). In a second controlled study of 53 analgesic abusers with a serum creatinine between 1.5 to 4 mg/dl in the absence of a clear renal diagnosis, a CT scan was performed and scored for the presence of decreased renal volume, bumpy contours and papillary calcifications. It was found that the renal image of analgesic nephropathy on CT scan in an early stage of renal failure is comparable with the observations made in ESRF patients. Particularly the demonstration of papillary calcifications showed a high sensitivity of 92% with a specificity of 100% for the early diagnosis of analgesic nephropathy.

Background: I-O Optimise is a new pan-European data platform developed to enable real-world insights into the management of thoracic malignancies. As part of this initiative, the current analysis reports the characteristics and treatment patterns for adult patients diagnosed with stage IIIB or IV NSCLC at Leeds Teaching Hospitals Trust (LTHT), hosting one of the largest integrated cancer centres in the UK. Method: Retrospective cohort study using longitudinal data already collected from electronic medical records at LTHT, including all adult patients diagnosed with stage IIIB-IV NSCLC between January 2007 and August 2017. Minimum follow-up was 6 months. Distinct lines of therapy (LoT) were identified using a clinically-verified algorithm based on the name and date of systemic anti-cancer therapy (SACT) administered and the gap between two treatments. Result: Overall, 2119 patients were included. Mean age at diagnosis was 71.4 ± 11.2 years. Nearly one-third (32.7%) were clinically diagnosed without pathological confirmation (TABLE) and very few of these patients have SACT administration recorded. Following diagnosis, 648 patients (30.6%) received 1 LoT, 223 (10.5%) 2 LoT and 60 (2.8%) 3 LoT. Proportions of patients treated decreased with age (73.5% [25/34] aged 18-44 years; 52.7% [267/507] aged 45-64 years; 29.8% [310/1040] aged 65-79 years; 8.6% [46/538] aged 80+ years) and performance score (58.5% [387/ 662] PS0-1; 38.2% [158/414] PS2; 6.1% [52/848] PS3-4). Between the periods 2007-2011 and 2012-2017, increased proportions were treated (28.2% [263/933] and 32.5% [385/1186] respectively). Patient characteristics of the treated cohort and regimens administered for 1 st and 2 nd LoT are shown (TABLE). Conclusion: Around 70% of this real-world cohort did not receive any SACT, and the administration of treatment was strongly associated with age and performance status. The changing availability of treatment options over time (including the emergence of immunotherapy) and survival outcomes by LoT will be presented in more detail for the cohort described.Background: Historically, CT studies are always viewed in several window settings, optimized to evaluate specific anatomic structures and regions (mediastinal, lung, bone and vascular window). A newly developed image processing technique fuses these conventional windows into a single "all-in-one" window. This new window is specifically designed for comparison and follow-up of CT studies in oncology. The purpose of this study is to compare lesion detection on this "all-in-one" window versus conventional window settings. Method: In this retrospective study, 50 consecutive thoracic oncology chest CT examinations, containing 417 documented lesions and features, were reviewed by 6 radiologists, subdivided into 2 groups of 3 radiologists each, with similar levels of expertise in each group (experienced, junior and radiology resident). All scans were reviewed in conventional window settings (as in routine daily practice), by one group and in the "all-inone" window by the other...
