Previous studies have reported the survival benefit after ruxolitinib treatment in patients with myelofibrosis (MF). However, population-based data of its efficacy are limited. We analyzed the effects of ruxolitinib in MF patients with data from the Korean National Health Insurance Database. In total, 1199 patients diagnosed with MF from January 2011 to December 2017 were identified, of which 731 were included in this study. Patients who received ruxolitinib (n = 224) were matched with those who did not receive the drug (n = 507) using the 1:1 greedy algorithm. Propensity scores were formulated using five variables: age, sex, previous history of arterial/venous thrombosis, and red blood cell (RBC) or platelet (PLT) transfusion dependence at the time of diagnosis. Cox regression analysis for overall survival (OS) revealed that ruxolitinib treatment (hazard ratio (HR), 0.67; p = 0.017) was significantly related to superior survival. In the multivariable analysis for OS, older age (HR, 1.07; p < 0.001), male sex (HR, 1.94; p = 0.021), and RBC (HR, 3.72; p < 0.001) or PLT (HR, 9.58; p = 0.001) transfusion dependence were significantly associated with poor survival, although type of MF did not significantly affect survival. Considering evidence supporting these results remains weak, further studies on the efficacy of ruxolitinib in other populations are needed.

De novo cases of metastatic prostate cancer (mCSPC) are associated with poorer prognosis. To assist in clinical decision-making, we aimed to determine the prognostic utility of commonly available laboratory-based markers with overall survival (OS). In a retrospective population-based study, a cohort of 3556 men aged ≥66 years diagnosed with de novo mCSPC between 2014 and 2019 was identified in Ontario (Canada) administrative database. OS was assessed by using the Kaplan–Meier method. Multivariate Cox regression analysis was performed to evaluate the association between laboratory markers and OS adjusting for patient and disease characteristics. Laboratory markers that were assessed include neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), albumin, hemoglobin, serum testosterone and PSA kinetics. Among the 3556 older men with de novo mCSPC, their median age was 77 years (IQR: 71–83). The median survival was 18 months (IQR: 10–31). In multivariate analysis, a statistically significant association with OS was observed with all the markers (NLR, PLR, albumin, hemoglobin, PSA decrease, reaching PSA nadir and a 50% PSA decline), except for testosterone levels. Our findings support the use of markers of systemic inflammation (NLR, PLR and albumin), hemoglobin and PSA metrics as prognostic indicators for OS in de novo mCSPC.

40 Background: Prostate cancer (PC) is the most common non-cutaneous cancer in Canadian men and the third most common cause of cancer death in Canada. Several studies have shown that use of commonly prescribed medications, including those used for diabetes and hypercholesterolemia, is associated with improved survival in various malignancies, including PC. There has not been any large population-based study, examining the effects of these and other commonly prescribed medications, on the rate of PC diagnosis, over a 20 years follow-up period. Methods: A retrospective population-based study using data from the institute of clinical evaluative sciences, including all male patients aged 65 and above in Ontario who have had a negative first prostate biopsy between 1994 and 2016. We assessed the impact of commonly prescribed medications on PC diagnosis. The medications included Statins (hydrophilic and hydrophobic), diabetes drugs (metformin, insulins, sulfonylureas, and thizolidinedions), proton pump inhibitors, 5 alpha reductase inhibitors, and alpha blockers. Time dependent Cox regression proportional hazards models were performed determine predictors of PC diagnosis. Medication exposure was time varying and modeled as “ever” vs. “never” use or as cumulative exposure for 6 months of usage. A priori variables included in the model included age, ADG comorbidity score, rurality index, index year, and all medications. Results: A total of 51,415 men were analyzed over a mean (SD) follow-up time of 8.06 (5.44) years. Overall, 10,466 patients (20.4%) were diagnosed with PC, 16,726 (32.5%) had died, and 1,460 (2.8%) patients died of PC. On multivariable analysis increasing age and rurality index were associated with higher PC diagnosis rate, while a more recent index year, and usage of hydrophilic statins was associated with a lower diagnosis rate in both “ever” vs. “never” and cumulative models (HR 0.832, 95% CI 0.732-0.946, p = 0.005, HR 0.973 95% CI 0.951-0.995, p = 0.016, respectively). Conclusions: Hydrophilic statins are associated with a clinically significant lower PC diagnosis. To our knowledge this is the first study demonstrating a clear advantage of one group of statins (hydrophilic) over another (hydrophobic) in PC prevention.

Objectives.A population-based study was undertaken to investigate the epidemiological features of gastrointestinal stromal tumors (GISTs) in Shanghai, especially the incidence and the preliminary exploration of survival.Methods.A total of 1923 patients with GISTs diagnosed from 2001 to 2010 in Shanghai were reviewed. The annual incidence and overall survival of GISTs were calculated; Cox proportional hazards’ regression was used to analyze several prognostic factors.Results.The average crude incidence of GISTs was 2.11 per 100,000 between 2004 and 2008, and the age-standardized incidence was 1.28 per 100,000. The incidence increased gradually from 2004 to 2008. In addition, 57% of cases had GIST in the stomach and 33% in the intestine. The 5-year overall survival of GISTs was 86.98%. The Cox regression analysis showed older age (≥65 yr versus <40 yr, HR = 5.085; (40, 65) yr versus <40 yr, HR = 1.975), male gender (HR = 1.474), and tumor locations (intestinal versus stomach, HR = 1.609) were predictors of its mortality.Conclusion.GISTs, mainly occurring in the stomach, are more common in elderly population, with an increasing incidence from 2004 to 2008. Older age, male gender, and tumor locations are risk factors for its mortality.

ObjectivesTo investigate the associations between echocardiographic left atrial (LA) size and incident stoke and stroke cause mortality among a rural population in China.DesignA prospective study.Setting and participantsBased on the Northeast China Rural Cardiovascular Health Study, we selected a total of 10 041 participants aged ≥35 years who agreed to have transthoracic echocardiography at baseline and were successfully followed up for incident stoke and stroke cause mortality.Primary outcome measureThe outcomes were stroke and stroke cause death according to medical records and death certificates during the follow-up period.ResultsLA enlargement (LAE) group had a higher prevalence of cardiovascular disease than normal LA diameter (LAD) group. After excluding individuals who had a prior stroke, subjects with LAE showed higher incident rates of stroke and its mortality in the overall and specific stratified analyses (all p<0.05). Kaplan-Meier analysis revealed that LAE could predict stroke incidence and stroke-free survival, but the association was no longer observed after the adjustment for potential confounding factors. Cox regression analysis reported that per 1 SD increment in LAD and LAD/body surface area (BSA) was associated with an increased incidence of stroke (LAD: HR=1.20, 95% CI 1.08 to 1.33, p<0.001; LAD/BSA: HR=1.22, 95% CI 1.11 to 1.35, p<0.001) and stroke cause mortality (LAD: HR=1.27, 95% CI 1.08 to 1.50, p<0.01; LAD/BSA: HR=1.41, 95% CI 1.20 to 1.65, p<0.001) in the total population, and similar trends were found in both genders (all p<0.05). LAD or LAD/BSA was related to ischaemic and haemorrhagic stroke incidence, and the risk of ischaemic and haemorrhagic stroke mortality (all p<0.05). The dose–response curves further suggested linear associations between LAD, LAD/BSA and the incidence of stroke and subsequent mortality in the general population (all p<0.05).ConclusionsOur population-based study implied that LA size, especially LAD and LAD/BSA, might be useful echocardiographic biomarkers that had the potential to predict incident stroke and stroke cause mortality.

Abstract Background Studies have shown that hyperglycemia in cirrhotic patients increases mortality. However, no population-based study has evaluated the influence of hypoglycemia upon hospital admission on death in these patients. The aim of this study was to assess the effect of hypoglycemia at admission on the mortality of patients with liver cirrhosis. Methods The Taiwan National Health Insurance Database was searched, and 636 cirrhotic patients without baseline diabetes mellitus who presented with hypoglycemia upon hospitalized from 2010 to 2013 were included in the study. A one-to-four propensity score matching was performed to select a comparison group based on age, sex and comorbidities. Results The overall 30-day mortality rate was 30.2% in the hypoglycemia group and 7.4% in the non-hypoglycemia group (P < 0.001). After Cox regression modeling adjusting for age, sex and comorbid disorders, cirrhotic patients with hypoglycemia had a hazard ratio (HR) of 30-day mortality of 4.96 (95% confidence interval [CI] 4.05–6.08, P < 0.001) as compared to the non-hypoglycemia group. In subgroup analysis, the cirrhotic patients with hypoglycemia and hepatocellular carcinoma (HCC) had a 30-day mortality HR of 6.11 (95% confidence interval [CI] 4.40–8.49, P < 0.001) compared to those with neither hypoglycemia nor HCC. Conclusions Hypoglycemia is a very important prognostic factor in the 30-day mortality of cirrhotic patients, especially in those with underlying HCC.

Abstract The positive association between metabolic syndrome (MetS) and hepatocellular carcinoma (HCC) has been suggested. However, no studies have yet looked at how the risk of developing HCC varies with changes in MetS status. Therefore, we aimed to investigate the association between changes in MetS and subsequent HCC development. Data were obtained from the Korean National Health Insurance Service. 5,975,308 individuals who participated in health screenings both in 2009–2010 and 2011–2012 were included. Subjects were divided into four groups according to change in MetS status during the two-year interval screening (from 2009 to 2011): sustained non-MetS, transition to MetS, transition to non-MetS, and sustained MetS. Cox regression analysis was used to examine the hazard ratios of HCC. During a median of 7.3 years follow-up, 25,880 incident HCCs were identified. Compared to the sustained non-MetS group, age, sex, smoking, alcohol, regular exercise, and body mass index-adjusted hazard ratios (95% confidence interval) for HCC development were 1.01 (0.97–1.05) for the transition to MetS group; 1.05 (1.003–1.09) for the transition to non-Met group; and 1.07 (1.03–1.10) for the sustained MetS group. Stratified analyses according to age, sex, smoking, alcohol intake, exercise, diabetes mellitus, hypertension, dyslipidemia, and chronic kidney disease showed similar results. A significantly increased HCC risk was observed in the sustained MetS and transition to non-MetS groups. The baseline status of MetS was associated with the risk of HCC development. Strategies to improve MetS, especially targeting insulin resistance might prevent HCC development.

Purpose: Gleason score (GS) system is one of the most widely used histological grading methods for prostate cancer (PCa) all over the world. GS can be obtained by adding the primary Gleason pattern (GP) and secondary GP. Different proportions of GP 4 and GP 5 in prostate specimens can both lead to GS 9. In this study, we explored whether GP 5 + 4 or GP 4 + 5 was associated with different prognoses among patients with GS 9 PCa.Materials and methods: A retrospective population-based study was conducted on 10,124 subjects diagnosed with GS 9 PCa between 2004 and 2009 from the Surveillance, Epidemiology, and End Results program. A 1:1 propensity-score matching (PSM) was performed to balance the baseline characteristics between the GP 4 + 5 and 5 + 4 groups and to compare the prognoses between the two groups. Cox regression analysis and Fine-Gray competing risk regression models were adopted to screen the covariates significantly associated with all-cause mortality (ACM) and cancer-specific mortality (CAM).Results: GP 5 + 4 was associated with higher risks of ACM and CSM before or after PSM than GP 4 + 5. In the original cohort, there were eight independent predictors for ACM, which were age at diagnosis, race, AJCC NM stage, PSA levels, treatments, GP, and marital status, confirmed by the Cox analysis; and nine independent predictors for CSM, which were age at diagnosis, race, AJCC TNM stage, PSA levels, treatments, GP, and marital status, confirmed by the competing-risk model.Conclusion: GP 5 + 4 was associated with a poorer overall survival and cancer-specific survival compared with GP 4 + 5.

Abstract Abstract 5077 Background: The benefit of adding Rituximab to combination chemotherapy in Follicular Lymphoma (FL) has been established in several randomized clinical trials (RCT). All of them have shown improvements in response rates, time to progression or overall survival (OS). The aim of the study was to assess the impact of the introduction of Rituximab in the treatment of FL in the general population of elderly patients, usually not included in RCT. Methods: All FL patients diagnosed in the province of Modena, Italy that had been diagnosed between 1997 and 2010 were identified from the archives of the Modena Cancer Registry that covers a population of approximately 600. 000 people. In the studied region Rituximab was available for first line treatment of FL since 2004. Therefore, for study purposes patients were grouped according to the year of diagnosis in 2 study periods (1997–2003, and 2004–2010). Elderly patients were defined using a cut off for age at 60 years. Clinical and treatment characteristics and also OS were compared according to the period of diagnosis and also, regarding the use or not of Rituximab as part of first line treatment. Moreover, a Cox regression analysis was performed to identify clinical factors and treatment characteristics associated with OS. Results: A total of 340 FL patients were identified of whom 177 (52%) were older than 60 years. No difference was found regarding clinical characteristics at diagnosis (age, gender, stage, bulky disease and LDH level) among study periods. Regarding treatment, no difference was found for the first general approach (watch and wait, chemotherapy or radiotherapy) across time. Among 229 patients initially treated with chemotherapy, antracyclines (ADM) or fludarabine (F)-based-regimens were the most frequently used. However, the use of ADM and/or F-based-regimens decreased from 82% (85/104) in the first period to 66% (83/125) in the last period (p=0. 03). Elderly patients (67%; 83/124) received less frequently ADM or F-based-regimens in comparison with younger patients (81%; 85/105) (P<0. 001). In contrast, the use of Rituximab alone or as part of front line treatment remarkably increased from 15% (16/104) in the first period to 94% (118/125) after 2003 (p<0. 001). This increase was also observed among elderly patients (8% (4/49) in the first period and 92% (69/75) in the last period, p<0. 001). After a median follow up of 68 months (range 8 to 176) for living patients, median OS was not reached. In univariate analysis factors associated with inferior OS were older age (>60), period of diagnosis before 2004, no use of Rituximab and abnormal LDH levels. The 5-years OS increased from 73% to 85% moving from first to second study periods (p=0. 008). In the Cox-Regression analysis, age > 60 (HR 11. 27 95%CI 5–25) and abnormal LDH level (HR 2. 7 95%CI 1. 56–4. 8) at diagnosis were identified as independent adverse risk factors. In contrast, the use of Rituximab yielded a protective effect (HR 0. 4 95%CI 0. 23–0. 79). In multivariate analysis period of diagnosis and use of Rituximab were mutually exclusive. Comparing young with elderly patients, only the latter group had a significant improvement in OS across the study periods: among the young, the 5-years OS in the first and second period was 89% and 98%, respectively, p= 0. 07; and among the elderly the 5-years OS in the first and second period was 58% and 72%, respectively p=0. 02. Conclusion: The present population based study showed a remarkable improvement in OS of FL patients after 2003, as a consequence of introduction of Rituximab as part of first line treatment. This improvement was mostly pronounced in the elderly population. Disclosures: No relevant conflicts of interest to declare.

e16553 Background: Prostate cancer (PC) is the most common non-cutaneous cancer in men and the third most common cause of cancer death in males. Several studies have shown that use of commonly prescribed medications, is associated with improved survival in various malignancies, including PC. There has not been any large population-based study, examining the effects of these and other commonly prescribed medications, such as proton pump inhibitors (PPI), on the rate of PC diagnosis, PC advanced disease and PC-specific death. Methods: A retrospective population-based study using data from the institute of clinical evaluative sciences, including all male patients aged 65 and above in Ontario who have had a negative first prostate biopsy between 1994 and 2016. We assessed the impact of commonly prescribed medications on PC outcomes. The analyzed medications included Statins (hydrophilic and hydrophobic), most commonly used diabetes drugs (metformin, insulins, sulfonylureas, and thizolidinedions), PPIs, 5 alpha reductase inhibitors, and alpha blockers. Time dependent Cox regression proportional hazards models were performed to determine predictors of PC diagnosis, PC advanced disease (defined as usage of hormonal therapy), and PC-specific death. Medication exposure was time varying and modelled as “ever” vs. “never” use or as cumulative exposure. Results: A total of 21,562 men were analyzed over a mean (SD) follow-up time of 8.06 (5.44) years. Overall, 5,187 patients (24%) were diagnosed with PC, 7861 (36.5%) had died, and 647 (3%) died of PC. On multivariable analysis usage of hydrophilic statins modelled as “ever vs. never” was associated with a lower diagnosis rate (OR 0.832, 95% CI 0.732-0.946, p = 0.005) and a significantly decreased PC-specific death (OR 0.676, 95% CI 0.528-0.871, p = 0.0024). In contrast, Pantoprazole was associated with a higher rate of advanced PC disease when modelled as cumulative exposure of 6 months (OR 1.03, 95% CI 1.003-1.06, P = 0.031), and PC-specific death, when modeled as “ever vs. never” (OR 1.26, 95% CI 1.02-1.576, p = 0.031). Conclusions: Hydrophilic statins were associated with a clinically and statistically significant lower PC diagnosis and PC-specific death, while pantoprazole was associated with a higher rate of advanced PC disease and PC-specific death.
