Abstract Background Patients with advanced body/tail pancreatic cancer have poor quality of life and low overall survival rate. In recent years, interventional diagnosis and treatment of advanced pancreatic cancer have become increasingly widespread. This retrospective cohort study investigated the efficacy of routine intravenous chemotherapy (the control group), transcatheter arterial infusion (TAI) chemotherapy, and TAI combined with radioactive particles as therapeutic methods for advanced body/tail cancer pancreatic by assessing the short-term and overall survival rates. Methods We screened our prospective database for patients with advanced body/tail pancreatic cancer, which tumor deemed unresectable and no other confirmed malignant tumors, patients were assigned into three groups according to their treatment. Analyses with regard to the clinical responses, the 6, 12, and 18-month survival rates and overall survival rates were performed. Results The median survival time was 6 months in the control group, 10 months in the TAI group and 13 months in the TAI combined group. The Kaplan–Meier estimates of the OS among the three groups, indicating that there is significant difference among three groups (P༜0.000). The clinical remission rates were 17.5% in the control group, 41.5% in the TAI group, and 48.0% in the TAI combined group. Covariates analyzed showed that different treatment methods and times affected the results significantly (P༜0.002). Conclusions In the treatment of advanced body/tail pancreatic cancer, TAI and TAI combined with radioactive particles significantly improved the clinical outcomes in patients compared with routine intravenous chemotherapy.

Abstract Background: It is well established that antiretroviral therapy (ART) is beneficial in reducing the mortality among patients with human immunodeficiency virus (HIV). In Malaysia, there is lack of study and information regarding the overall survival rates and prognostic factors for survival in HIV-infected adults treated with ART. Therefore, this study aimed to assess and compare the survival rates as well as to identify the prognostic factors for survival among HIV adults in Malaysia.Methods: A retrospective cohort study was conducted by reviewing the medical records of HIV patients who started ART between year 2007 and 2016 at a tertiary referral hospital in Malaysia. ART-naive adults aged 15 years and above were included and those who were transferred out were excluded. After applying inclusion and exclusion criteria, there were 339 cases eligible in this study. Systematic sampling method was applied. Kaplan Meier survival curve and log-rank test were used to compare the overall survival rates. Cox proportional hazards regression was applied to determine the prognostic factors for survival.Results: The estimated overall survival rates were 95.9%, 93.8%, 90.4%, 84.9%, and 72.8% at 6 months, 1 year, 3 years, 5 years and 10 years, respectively. The overall survival rates were significantly different according to age group (p<0.001), employment status (p<0.001), transmission mode (p=0.003), and history of illicit drug use (p=0.017), baseline CD4 cell count (p<0.001), baseline haemoglobin level (p<0.001), tuberculosis co-infection (p<0.001), hepatitis co-infection (p=0.008), first NRTI (p<0.001) and history of defaults (p=0.021). Based on multiple Cox regression, patients who were anaemic had 3.76 times (95% CI: 1.97, 7.18; p<0.001) higher hazard of death than their non-anaemic counterparts. The hazard risk was 2.09 times (95% CI: 1.10, 3.96; p=0.024) higher among HIV patients co-infected with tuberculosis compared to those who were not. Conclusion: Overall survival rates were higher than low-income countries but lower than in high-income countries, and comparable with middle-income countries. Low baseline haemoglobin level and tuberculosis co-infection were strong prognostic factors for HIV survival

248 Background: With technological development and awareness of efficacy, radiotherapy (RT) is more frequently adopted in management of hepatocellular carcinoma (HCC). To assess the efficacy of RT, we conducted this retrospective cohort study from a single institute. Methods: The analysis involved 822 patients who underwent definitive or salvage RT for locally advanced HCC from January 1997 to August 2009. Two-dimensional RT, 3-dimensional conformal RT (3D-CRT), and intensity-modulated RT including tomotherapy (IMRT) were carried out for 186 (22.6%), 579 (70.4%), and 57 (6.9%) patients, respectively. In a majority of patients, RT was done either concurrently with intra-arterial 5-FU (500 mg/m2) chemotherapy (CCRT group; 326 patients, 39.7%), or following transarterial chemoembolization (TACE+RT group; 244 patients, 29.7%). Total radiation dose was 30 to 64.8 Gy (median dose 45 Gy) in 1.8-2 Gy fraction. Results: The median age of total 822 patients was 55 and 84.3% was male. The 2, 3, and 4-year overall survival rates of total patients were 21.2, 13.1, and 10.1%, respectively. In 2-year survival, the patients with Child-Pugh class A did better than B or C (23% vs 10.9%, p<0.001), without portal vein thrombosis (PVT) did better than with PVT (26.8% vs 14.3%, p<0.001), and without lymph node metastasis (LNM) did better than with LNM (22.9% vs 11.7%, p<0.001). Patients with total dose higher than 45 Gy did better than those with less than 45 Gy (30.1% vs. 15.6%, p<0.001). The best outcome was shown in patients received higher than 45 Gy using 3D-CRT or IMRT, with 2-year overall survival rates of 25.9% (CCRT) and 41.3% (TACE+RT). Conclusions: This study showed a substantial effect of RT in locally advanced HCC. Further analysis will be continued to provide the best option of radiotherapy for locally advanced HCC.

Abstract Background Western multicenter studies on distal pancreatectomy with celiac axis resection (DP-CAR), also known as the Appleby procedure, for locally advanced pancreatic cancer are lacking. We aimed to study overall survival, morbidity, mortality and the impact of preoperative hepatic artery embolization (PHAE). Methods Retrospective cohort study within the European-African Hepato-Pancreato-Biliary-Association, on DP-CAR between 1-1-2000 and 6-1-2016. Primary endpoint was overall survival. Secondary endpoints were radicality (R0-resection), 90-day mortality, major morbidity, and pancreatic fistulae (grade B/C). Results We included 68 patients from 20 hospitals in 12 countries. Postoperatively, 53% of patients had R0-resection, 25% major morbidity, 21% an ISGPS grade B/C pancreatic fistula, and 16% mortality. In total, 82% received (neo-)adjuvant chemotherapy and median overall survival in 62 patients with pancreatic ductal adenocarcinoma patients was 18 months (CI 10–37). We observed no impact of PHAE on ischemic complications. Conclusions DP-CAR combined with chemotherapy for locally advanced pancreatic cancer is associated with acceptable overall survival. The 90-day mortality is too high and should be reduced. Future studies should investigate to what extent increasing surgical volume or better patient selection can improve outcomes.

Abstract Background: Since ovarian stimulation was introduced as an assisted reproductive technology, poor ovarian response (POR) management has challenged clinicians. Guidance on optimally managing patients with poor response and/or low sensitivity to ovarian stimulation is still lacking. We aimed to investigate whether a clomiphene citrate (CC) priming protocol could increase ovarian sensitivity in poor ovarian responders. Methods: This single-center retrospective cohort study included 294 patients (374 ovarian stimulation cycles). Of these, 193 cycles were treated by a CC priming antagonist protocol (study group) and 181 by the classical flexible gonadotropin-releasing hormone antagonist protocol (control group). Stimulation data and laboratory and clinical outcomes were compared between the groups. Results: Total gonadotropin dosage and dosage per follicle were considerably lower, the follicle-to-oocyte index was significantly higher, and the gonadotropin duration was shorter in the study group. After adjusting for potential confounders, multivariate regression analysis showed that cumulative ongoing pregnancy remained comparable between the groups (adjusted odds ratio: 0.761, 95% confidence interval: 0.300-1.933, P = 0.566). Age, body mass index, gonadotropin dosage per follicle, and the follicle-to-oocyte index were directly associated with the reproductive outcomes. The result of the sensitivity analysis showed that patients stimulated by the CC priming antagonist protocol were administered less gonadotropin (1,739.09 ± 719.39 vs. 3,114.77 ± 1,171.23, P < 0.001) at a lower gonadotropin dosage per follicle (637.36 ± 373.05 vs. 1286.26 ± 976.66, P < 0.001) and for a shorter duration (6.58 ± 2.23 vs. 9.80 ± 1.90, P < 0.001). Conclusions: The CC priming antagonist protocol offered a convenient and patient-friendly way to increase ovarian sensitivity during ovarian stimulation in poor ovarian responders.

Incidence Of Dementia

Abstract BACKGROUND Stroke has been recognized as one of the major causes of adult disability worldwide, and post-stroke dementia may affect up to one-third of stroke survivors. This condition could be prevented if we could recognize and treat it earlier. Acupuncture as a complementary treatment for stroke has been shown to be beneficial for subsequent post-stroke rehabilitation. Our study investigated if acupuncture served additional advantages to decreasing the incidence of post-stroke dementia. METHODS We provide a retrospective cohort study from Taiwan National Health Insurance Research Database. This study compared the incidence of post-stroke dementia between cohorts with and without acupuncture treatment by calculating adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) of acupuncture associated with post-stroke dementia using Cox proportional hazard regressions. The study group was composed of 9,547 patients who received first hospitalization for the treatment of stroke between 2002 and 2004; of which, 47,735 comparison patients were defined as the control group. The two groups were followed-up until the diagnosis of dementia presented or until the end of 2007. RESULTS The adjusted HRs of developing dementia among patients with stroke was 4.705 times the average (range, 4.353–5.085), and the incidence of dementia was higher in males. The study group tended to have less incidence of all kinds of dementia after acupuncture treatment, and patients without stroke receiving acupuncture had a lower probability of dementia than those untreated during the follow-up period. CONCLUSIONS This study presents evidence that acupuncture serves as an effective and alternative procedure to lower the risk of post-stroke dementia and the overall incidence of dementia in Taiwanese population.

e19005 Background: CALGB 10403 is a pediatric-inspired ALL regimen that has recently been shown to have improved survival rates in adolescents and young adults with ALL when compared to historical outcomes with traditional adult ALL regimens (Stock et. al, 2019). Methods: This is a retrospective cohort study of ALL patients who received induction CALGB 10403 at Stanford University (both on and off trial), achieved CR1, and subsequently relapsed. Primary outcome of interest was event free survival from time of diagnosis. Events were defined as relapse or death. Secondary outcomes were overall survival and event free survival from first relapse. Patients were censored at time of last clinical follow up. Results: 25 patients met inclusion criteria and received front-line CALGB 10403 from April 2010 to September 2018. At the time of initial diagnosis median age was 30 years (range 18 – 39 years). 68% of patients were male. 48% of patients were overweight and 40% were obese. 76% of patients had precursor B cell ALL while 24% had T cell ALL. 12% had CNS disease at diagnosis. 36% of patients had WBC greater than 30k. 12% of patients had CRLF2 rearrangement. 12% of patients were MRD positive after first induction. 20% of patients received rituximab. Median event free survival time from diagnosis was 20 months (range 3 – 79 months) and median overall survival time was 53 months. Blinatumomab was the most common salvage therapy after 1st relapse, followed by inotuzumab. 15 patients (60%) achieved CR2, of which 4 (27%) were MRD positive after 2nd induction. 15 patients (60%) went to HSCT. Of the patients who achieved CR2, 8 relapsed for a second time. Median event free survival time after first relapse was 23 months. Survival 1 year after relapse was 60%. 11 of the 25 patients were alive at last follow up. Median follow up time of survivors was 6 years. Conclusions: This is a descriptive retrospective cohort study of adult patients in a real world setting who received CALGB 10403 induction and subsequently relapsed. Compared to other studies of relapsed ALL patients who were induced with traditional chemotherapy (Fielding et. al, 2007), survival 1 year after relapse was much higher (60% vs. 22%). As CALGB 10403 becomes an increasingly common induction regimen for AYA and adults with ALL, further outcomes study is required.[Table: see text]
