Aim: To report the outcomes and prognosis of patients with malignant pleural mesothelioma (MPM) who present with or develop metastases during treatment. Methods: This is a retrospective observational study of patients diagnosed with MPM over 7 years. Metastases at presentation or during follow-up were recorded. Multivariate Cox regression was used to evaluate the relationship of clinicopathologic variables and overall survival (OS). Logistic regression was used for propensity score matching of patients to assess chemotherapy treatment effect. Results: There were 367 patients included with a median age of 71 years (range, 29–91). A total of 69 patients (18%) had metastases: 14 at presentation and 55 during follow-up. Patients presenting with metastases had significantly worse median and 2-year OS compared to those developing metastases during follow-up: 13.3 months (95% confidence interval [CI], 2–24.6 months) and 0% versus 20.2 months (95% CI, 16.7–23.3 months) and 33%, respectively ( p = 0.029). Female sex, age >70 years, nonepithelioid histology, and not receiving chemotherapy were independent poor prognostic factors. There was no difference in OS of patients with locally advanced (T4) disease compared to metastatic disease (M1): median OS 10.7 months (95% CI, 5.9–15.6) versus 13.3 months (95% CI, 2–24.6) ( p = 0.18), respectively. Following propensity matching, sarcomatoid histology (hazard ratio, 7.86 [95% CI, 3.64–16.95]; p < 0.001) and multiple lines of chemotherapy (hazard ratio, 0.38 [95% CI, 0.19–0.84]; p = 0.015) were significant independent prognostic factors for OS. Conclusions: T4 disease carries a similar OS as metastatic MPM. Female sex, advanced age, nonepithelioid histology, and not receiving chemotherapy were independent poor prognostic factors.

e18509 Background: The prognostic systems currently in use in MPM, such as the EORTC and CALGB score, include the clinical and histological parameters, excluding the FDG-PET (PET) evaluation and the possibility of surgery. The aim of our study was to investigate the role of PET baseline SUV-max and surgery as prognostic factors in MPM. Methods: From April 2002to December 2012, 48 pts with a certain histological diagnosis of MPM underwent staging by PET scan before peri-operative (multimodality treatment) or palliative first-line chemotherapy (CT). Surgery was performed in 22(45.8%) pts. Pt characteristics: males 44(91.7%), females 4(8.3%); median age 65 (51-77) years; ECOG PS 0-1 45(93.7 %), PS 2 3(6.3 %); IMIG stage I-II 18(37.5%), III-IV 30(62.5%); histological subtype epithelial 40(83.3%), mixed 5(10.4%), sarcomatoid 3(6.3%); extrapleural pneumonectomy 8(16.8%), pleurectomy/decortication 14(29.2%), 17 (35.4%) VATS plus pleurodesis, 19(39.6%) no surgical procedures. Platinum based CT was performed in combination with pemetrexed in 39(81.3%) pts and with gemcitabine in 9(18.7%). According to the EORTC score 30(62.5%) pts were classified in the good prognosis group and 18(37.5%) as poor prognosis. The cut-off value of PET baseline SUV-max calculated by ROC analysis was 9; SUV-max at baseline PET was ≤ 9 in 32(66.7%) pts and >9 in 16(33.3%). Median overall survival (OS) was 12 (3-60) months. Results: Upon validating the impact of individual factors on OS using the Kaplan-Meier analysis, we found statistical significance was reached by histology (p=0.0038) and surgery (p=0.0027). In a multivariate analysis using the Cox regression system, considering OS as a dependent variable, according to age, histology, stage, PET baseline SUV-max and surgery, epithelial histology (p =0.002) and surgery (p=0.012) achieved a statistical significance. SUV-max at baseline PET was not statistically significant (p = 0.290), excluding it as a possible independent prognostic factor in MPM. Conclusions: This analysis does not indicate any prognostic value for baseline PET in MPM, confirming the importance of histological subtype and introducing surgery as a possible prognostic factor.

Background: There is a need for identifying risk factors for hospitalization in Parkinson’s disease (PD) and also interventions to reduce acute hospital admission. Objective: To analyze the frequency, causes, and predictors of acute hospitalization (AH) in PD patients from a Spanish cohort. Methods: PD patients recruited from 35 centers of Spain from the COPPADIS-2015 (COhort of Patients with PArkinson’s DIsease in Spain, 2015) cohort from January 2016 to November 2017, were included in the study. In order to identify predictors of AH, Kaplan-Meier estimates of factors considered as potential predictors were obtained and Cox regression performed on time to hospital encounter 1-year after the baseline visit. Results: Thirty-five out of 605 (5.8%) PD patients (62.5±8.9 years old; 59.8% males) presented an AH during the 1-year follow-up after the baseline visit. Traumatic falls represented the most frequent cause of admission, being 23.7% of all acute hospitalizations. To suffer from motor fluctuations (HR [hazard ratio] 2.461; 95% CI, 1.065–5.678; p = 0.035), a very severe non-motor symptoms burden (HR [hazard ratio] 2.828; 95% CI, 1.319–6.063; p = 0.008), falls (HR 3.966; 95% CI 1.757–8.470; p = 0.001), and dysphagia (HR 2.356; 95% CI 1.124–4.941; p = 0.023) was associated with AH after adjustment to age, gender, disease duration, levodopa equivalent daily dose, total number of non-antiparkinsonian drugs, and UPDRS-IIIOFF. Of the previous variables, only falls (HR 2.998; 95% CI 1.080–8.322; p = 0.035) was an independent predictor of AH. Conclusion: Falls is an independent predictor of AH in PD patients.

Background:Several studies have been conducted on factors associated with mortality in idiopathic inflammatory myopathies (IIM), but few studies have assessed prognostic factors for steroid-free remission in IIM.Objectives:We investigated the various clinical factors, including body measurements, that affect IIM treatment outcomes.Methods:Patients who were newly diagnosed with IIM between 2000 and 2018 were included. Steroid-free remission was defined as at least three months of normalisation of muscle enzymes and no detectable clinical disease activity. The factors associated with steroid-free remission were evaluated by a Cox regression analysis.Results:Of the 106 IIM patients, 35 displayed steroid-free remission during follow-up periods. In the multivariable Cox regression analyses, immunosuppressants’ early use within one month after diagnosis [hazard ratio (HR) 6.21, 95% confidence interval (CI) 2.61–14.74, p < 0.001] and sex-specific height quartiles (second and third quartiles versus first quartile, HR 3.65, 95% CI 1.40–9.51, p = 0.008 and HR 2.88, 95% CI 1.13–7.32, p = 0.027, respectively) were positively associated with steroid-free remission. Polymyositis versus dermatomyositis (HR 0.21, 95% CI 0.09–0.53, p = 0.001), presence of dysphagia (HR 0.15, CI 0.05–0.50, p = 0.002) and highest versus lowest quartile of waist circumference (WC) (HR 0.24, 95% CI 0.07–0.85, p = 0.027) were negatively associated with steroid-free remission.Conclusion:The early initiation of immunosuppressant therapy, type of myositis and presence of dysphagia are strong predictors of steroid-free remission in IIM; moreover, height and WC measurements at baseline may provide additional important prognostic value.Disclosure of Interests:None declared

8507 Background: All patients with malignant pleural mesothelioma (MPM) eventually relapse following standard chemotherapy. However, there is no standard treatment option in this setting. Vinorelbine, exhibits useful clinical activity but has not been formally evaluated in a randomised clinical trial, despite its widespread off-label use worldwide. BRCA1 regulates spindle assembly checkpoint in MPM and predicts vinorelbine sensitivity in preclinical models [1,2], suggesting that BRCA1 negative patients may be chemoresistant. Methods: VIM, a Cancer Research UK funded, investigator-initiated randomised controlled phase 2 multi-centre UK trial, enrolled patients with MPM who had progressed after first-line chemotherapy. Pts were randomised 2:1 to either vinorelbine (60mg/m2 weekly Q21d escalating to 80mg/m2 from cycle 2) + active supportive care (ASC) versus ASC until disease progression, unacceptable toxicity or withdrawal of consent. The primary outcome was progression free survival (PFS) defined as the time from randomisation to any progression (based on Modified RECIST criteria for assessment of response in malignant pleural mesothelioma) or death. The trial had 90% power to detect a hazard ratio of 0.65 at the one-sided 20% significance level. Secondary endpoints were overall survival (OS), tolerability and safety. Results: Between May 2016 and Oct 2018, 154 patients were recruited from 10 UK sites and randomised to vinorelbine + ASC (n=98) or ASC alone (n=56). In the Intention-to-treat analysis, after 129 events, median PFS was 4.2 months (m) for vinorelbine + ASC compared to 2.8m for ASC alone (Hazard Ratio (HR) 0.59; 95% CI: 0.41 to 0.85; one-sided p = 0.0017). 108 deaths were reported. Median OS was 9.3m for vinorelbine + ASC compared to 9.1m for ASC alone (HR=0.79; 95% CI: 0.53 to 1.17; two-sided p = 0.24). Toxicity data and subgroup analyses including the impact of BRCA1 deficiency will be presented. Conclusion: The trial met its primary endpoint. Vinorelbine demonstrates useful clinical efficacy in relapsed MPM, supporting its off-label use, as a treatment option for patients with relapsed MPM.[1] Busacca et al, J Pathol 2012, 227(2), 200.

Cxcr4 Axis

Previous studies have demonstrated that CXCL12/CXCR4 axis is closely related to tumors such as malignant pleural mesothelioma (MPM). This research was conducted in order to detect whether CXCL12/CXCR4 inhibitors could restrain MPM and have a synergistic effect with chemotherapy, also to investigate the relationship of CXCL12/CXCR4 with other gene expressions in MPM. Forty mice were injected MPM cells and randomly divided into four groups: the PBS (control group), AMD3100 (CXCR4-CXCL12 antagonist), pemetrexed and AMD3100 plus pemetrexed. The mice were treated respectively for duration of 3 weeks. The size, bioluminescence and weight of tumors were measured. The differences between gene expressions in each group were analyzed. The tumor weights of each treatment group were lower than that of the control group (p<0.05). The bioluminescence of the tumor of the AMD3100 treatment group and the AMD3100 plus pemetrexed treatment group were lower than that of the control group (p<0.05), and AMD3100 was shown to have synergistic effects with pemetrexed (p<0.05). Among the 2.5 billion genes, several hundreds of genes expressed differently between groups. Results show that AMD3100 and pemetrexed can inhibit the growth of MPM in vivo, also that there is a better result if both are used together. Our findings suggest that CXCL12/CXCR4 axis affects a certain amount of gene expression in MPM.

Abstract Background The effect of renal biopsy on the prognosis of elderly patients with chronic kidney disease remains unclear. Thus, in this study, we aimed to evaluate the relationship between renal biopsy and renal survival in this population.Methods In this multi-centre retrospective study, the baseline characteristics among three groups were balanced by propensity matching. All patients were divided into three groups according to age and renal biopsy. The clinicopathological features at biopsy and renal outcomes during the follow-up were collected and analysed. Renal outcomes were defined as estimated glomerular filtration rate < 15 mL/min/1.73 m2, dialysis, renal transplantation, or death. The prognostic effects of renal biopsy were evaluated using Cox regression models. Results A total of 1313 patients were identified. After propensity matching, 390 patients were selected and divided into three groups. After a total follow-up period of 55 months, 20 (13.3%) patients (47.6% group 1 vs 7.41% group 2 vs 39.1% group 3) reached renal outcomes. No significant differences were found in renal outcomes among aged patients whether they underwent renal biopsy or not. Cox regression analysis revealed risk factors in aged patients including low albumin and high levels of proteinuria and serum creatinine (P < 0.05). Platelet count was significant only in aged patients who underwent renal biopsy (hazard ratio: 0.642, P < 0.05). Conclusion In conclusion, renal biopsy in the elderly has not shown benefits in terms of renal survival, conservative treatment appears to be a viable therapeutic option in the management of those people.

Abstract Background For recanalization of coronary chronic total occlusion (CTO) lesions, subintimal guidewire tracking in both antegrade and retrograde approaches are commonly used. Purpose This study aimed to assess the impact of subintimal tracking on long-term clinical outcomes after recanalization of CTO lesions. Methods Between January 2009 and December 2016, 474 CTO lesions (434patients) were successfully recanalized in our center. After guidewire crossing in a CTO lesion, those lesions were divided into intimal tracking group (84.6%, n=401) and subintimal tracking group (15.4%, n=73) according to intravascular ultrasound (IVUS) findings. Long-term clinical outcomes including death, target lesion revascularization (TLR), target vessel revascularization (TVR) were compared between the two groups. In addition, the rate of re-occlusion after successful revascularization was also evaluated. Results The median follow-up period was 4.7 years (interquartile range, 2.8–6.1). There was no significant difference of the rate of cardiac death between the two groups (intimal tracking vs. subintimal tracking: 7.0% vs. 4.1%; hazard ratio, 0.61; 95% confidence interval [CI], 0.19 to 2.00; p=0.41), TLR (14.3% vs. 16.2%; hazard ratio, 1.34; 95% CI, 0.71 to 2.53; p=0.37), and TVR (17.5% vs. 20.3%; hazard ratio, 1.27; 95% CI, 0.72 to 2.23; p=0.42). However, the rate of re-occlusion was significantly higher in the subintimal tracking group than intimal tracking group at 3-years re-occlusion (4.2% vs. 14.5%; log-rank test, p=0.002, Figure). In the multivariate COX regression, subintimal guidewire tracking was an independent predictor of re-occlusion after CTO recanalization (HR: 5.40; 95% CI: 2.11–13.80; p<0.001). Figure 1 Conclusions Subintimal guidewire tracking for recanalization of coronary CTO was associated with significantly higher incidence of target lesion re-occlusion during long-term follow-up period.
