Abstract Background. A recent phase III trial (AZA-001) showed AZA is the first treatment to significantly extend overall survival (OS) in higher-risk MDS patients (pts) (Blood2007;110:817). MDS incidence increases with age resulting in limited treatment options, particularly for those ≥75 years of age, given the poor tolerability and ineffectiveness of cytotoxic therapies. This subgroup analysis compared the effects of AZA vs CCR on OS, hematologic improvement (HI), transfusion independence (TI), and tolerability in pts ≥75 yrs of age. Methods. Higher-risk MDS (FAB: RAEB, RAEB-T, CMML and IPSS: Int-2 or High) pts were enrolled. All pts were pre-selected by site investigators – based on age, performance status, and comorbidities – to receive 1 of 3 CCR: best supportive care only (BSC); lowdose ara-C (LDAC), or intensive chemotherapy (IC). Pts were then randomized to AZA (75 mg/m2/d SC × 7d q 28d), or to CCR. Those randomized to AZA received AZA; those randomized to CCR received their pre-selected treatment. Randomization was stratified based on FAB subtype (RAEB and RAEB-T) and IPSS (Int-2 or High). Erythropoiesis stimulating agents were disallowed. OS was assessed using Kaplan-Meier (KM) methods and HI and TI were assessed per IWG 2000. To adjust for baseline imbalances, a Cox proportional hazards model was used, with ECOG status, LDH, number of RBC transfusions, Hgb, and presence or absence of -7/del(7q) at baseline as variables in the final model. Adverse events (AEs) were evaluated using NCI-CTC v. 2.0. Results. Of all enrolled pts (N=358, median age 69 yrs), 87 pts (24%) were ≥75 yrs of age (AZA n=38, CCR n=49 [BSC, n=33; LDAC, n=14; IC, n=2]). The majority of pts randomized to CCR received BSC only, suggesting clinicians are generally reticent to use active treatment in this population. Similar to the overall AZA-001 results, treatment with AZA was associated with prolonged survival in pts ≥75 yrs of age, with KM median OS in the AZA group not reached at 17.7 months of follow-up, vs KM median OS for CCR at 10.8 months (HR: 0.48 [95%CI: 0.26, 0.89]; p=0.0193). In these pts, OS rates at 2 years were significantly higher in the AZA group vs CCR: 55% vs 15% (p=0.0003). Two-fold more RBC transfusion-dependent pts at baseline in the AZA group achieved TI vs CCR: 10/23 (44%) vs 7/32 (22%), p=0.1386, respectively. Similarly, more pts in the AZA group achieved HI (major + minor) vs CCR: 58% vs 39%, (p=0.0875), respectively. As previously reported, AZA was generally well tolerated. Anemia, neutropenia, and thrombocytopenia were seen in 42%, 66%, and 71% of pts in the AZA group, respectively, vs 47%, 26%, and 40% in the CCR group, who were predominately receiving BSC only. Infections were reported by 79% and 60% of AZA and CCR pts, respectively. Discontinuations due to an AE occurred in 13% of AZA and 8% of CCR pts ≥75 yrs of age. Conclusion. Data from this subgroup analysis indicate pts ≥75 yrs of age with higher-risk MDS receiving active treatment with AZA experience significantly prolonged 2-year OS and reduced risk of death. AZA is generally well tolerated in this elderly patient population.

e21579 Background: P and P+C are standard-of-care (SOC) treatment options for advanced NSCLC. However, they have not yet been directly compared in clinical trials. Methods: We conducted a retrospective cohort study of patients with advanced NSCLC who initiated treatment with SOC P±C at our center from 2/11/16 to 10/15/19 (data cutoff 1/15/20). Patient demographic, clinicopathologic, therapeutic and outcomes data were extracted. All radiographic scans were independently evaluated by a thoracic radiologist using iRECIST. Survival time was defined from the start of P±C. Kaplan-Meier and Cox proportional hazards model were utilized. Results: Of 103 patients with median follow up of 17.7 months, 74 (71.8%) had received P, while 29 (28.2%) had received P+C. In PD-L1 tumor proportion score (TPS) unselected population, there were no significant differences in age, sex, smoking status, driver mutation, tumor mutational burden (TMB), line of therapy, ECOG performance status (PS) or immune-related adverse events (irAE) between P and P+C groups. 71.6% in P vs 13.8% in P+C had PD-L1 TPS ≥50% (p < 0.001). There were no significant differences between the two groups in objective response rate (ORR), disease control rate (DCR), unadjusted progression-free survival (PFS) or unadjusted overall survival (OS) (Table). Multivariable adjustment for confounding factors between P+C vs P revealed no differences in OS [hazard ratio (HR) for death, 1.53, 95% CI 0.55 – 4.25] or PFS [HR for progression/death, 1.75, 95% CI 0.63 – 4.91]. Further stratification into PD-L1 TPS ≥50% and < 50% showed no significant differences between P+C vs. P in adjusted OS [HR for death, TPS < 50%- 1.54 (95% CI 0.59 – 4.03); TPS ≥50%- 0.71 (95% CI 0.11 – 4.52)] or PFS [HR for progression/death, TPS < 50%- 1.58 (95% CI 0.72 – 3.48); TPS ≥50%- 0.64 (95% CI 0.06 – 6.93)]. ECOG PS and development of irAE influenced OS in all groups, while TMB was relevant in PD-L1 ≥50% only. Conclusions: Our study shows no significant differences in outcomes with P vs P+C in advanced NSCLC in a real-world setting, albeit with limitations of single-center design, limited sample size, different line settings and lack of disease burden stratification. Ongoing phase III trials comparing front line P vs P+C will definitively address the long-term clinical benefits -if any- of combining cytotoxic chemotherapy with anti-PD-1 drugs. [Table: see text]

Abstract Background. Azacitidine (AZA), as demonstrated in the phase III trial (AZA-001), is the first MDS treatment to significantly prolong OS in higher-risk MDS pts (Blood2007; 110:817). Approximately one third of the pts enrolled in AZA-001 were FAB RAEB-T (≥20%–30% blasts) and now meet the WHO criteria for AML (Blood1999;17:3835). Considering the poor prognosis (median survival <1 year) and the poor response to chemotherapy in these pts, this subgroup analysis evaluated the effects of AZA vs CCR on OS and on response rates in pts with WHO AML. Methods. The AZA-001 trial enrolled higher-risk MDS pts (FAB: RAEB, RAEB-T, CMML and IPSS: Int-2 or High). Prior to randomization, site investigators preselected (based on age, performance status, and comorbidities) 1 of 3 CCR: best supportive care only (BSC); low-dose ara-C (LDAC), or intensive chemotherapy (IC). Pts were subsequently randomized 1:1 to AZA (75 mg/m2/d SC × 7d q 28d) or CCR; pts randomized to CCR received their investigator preselected treatment. Karyotypes were reclassified using AML standards: favorable {inv 16, t(8;21)}, unfavorable (−7/7q- or complex) and intermediate (all others including normal). OS was assessed by Kaplan-Meier (KM) methods and Cox proportional hazards model; and IWG AML criteria (J Clin Oncol2003;214642–9) were used to assess morphologic complete remissions (CR). Efficacy analyses included all WHO AML pts randomized. All pts were followed until death or study closure. Results. Of 358 enrolled pts, 113 met the definition for WHO AML (median: 23% blasts) of whom 86% were considered unfit for IC and were preselected by investigators to receive a low intensity regimen (BSC or LDAC). 55 of the 113 pts were randomized to AZA and 58 pts to CCR. AZA and CCR groups had comparable baseline demographic and clinical characteristics. Of the 58 pts randomized to CCR, 5 withdrew without receiving treatment and 53 were treated with their investigator preselected treatment as follows: IC (19%;10/53), LDAC (34%; 18/53) and BSC (47 %; 25/53). Of the 55 pts randomized to AZA, 2 withdrew without receiving treatment. Median age was 70 years; 24% had an unfavorable karyotype, 72% had an intermediate karyotype (including 46% normal); no pts had a favorable karyotype. Median follow-up for OS was 20.1 months. Median (min–max) number of treatment cycles was 8 (1–39) for AZA, 2.5 (1–3) for IC; 5.5 (1–14) for LDAC; and 6 months (2 – 19) for BSC. KM median OS was 24.5 vs. 16.0 months, respectively, in the AZA and CCR groups, hazard ratio (HR)=0.47, 95% CI, 0.28 to 0.79, p=0.004, Figure. OS rates at 2 yrs were 50% and 16%, respectively, in the AZA and CCR groups, p=0.0007. There was no statistical difference in the morphologic CR rate between the AZA (18%, 10/55) and CCR groups (16%, 9/58; p=0.80). OS results in cytogenetic intermediate pts showed a significant HR favoring the AZA group (N=38) over CCR (N=43, HR= 0.47 [95% CI: 0.24, 0.91], p=0.024) but not in pts with unfavorable cytogenetics: AZA (N=14) vs CCR (N=13, HR=0.66 [95% CI: 0.26, 1.68], p=0.381); however, pt numbers were low. WHO AML pt outcome measures showed significant benefits with AZA: fewer infections requiring IV antibiotics per pt-year in the AZA group (0.58) vs CCR (1.14, HR=0.51 [95% CI 0.29, 0.78], p=0.003); and reduced rates of hospitalization in the AZA group (3.4 per pt-year) vs CCR (4.3 per pt-year, HR=0.79 [95% CI 0.62, 1.00], p=0.028). AZA was generally well tolerated. Conclusion. AZA significantly prolongs OS with significant improvements in important pt outcomes in elderly WHO AML pts with low marrow blast counts, who currently have limited therapeutic options. Trials are ongoing to confirm the effect of AZA in elderly AML pts with more proliferative disease. Figure. Figure.

8541 Background: Ipilimumab (IPI) is a fully human monoclonal antibody directed against CTLA-4 that is being developed as a novel immunotherapeutic agent against melanoma and other solid tumors. The objective of this analysis was to retrospectively characterize the exposure-response (E-R) relationships for efficacy (overall survival, OS) in subjects with previously untreated advanced melanoma (pu-MEL), and safety (immune related adverse-events, irAEs) in subjects with previously treated advanced melanoma (pt-MEL) or pu-MEL. Methods: The E-R analysis of OS included 498 pu-MEL from a phase III study (CA184024) of IPI administered at 10 mg/kg + dacarbazine (DTIC) or DTIC + placebo; and the E-R analyses of irAE included 1036 subjects from a phase I study (CA184078), 4 phase IIstudies (CA184004/007/008/022) and CA184024 of IPI administered at doses of 0.3, 3 or 10 mg/kg. The relationship between steady‑state IPI trough concentration (Cminss) and OS was described using a Cox proportional hazards model, and the relationships between Cminss and incidence of irAEs were described by ordinal logistic regression models (separate models for any irAE, as well as skin, liver and GI irAE). Results: The risk of death decreased with increasing Cminss, and is higher for subjects with elevated baseline LDH level. The risk of death was higher for subjects with baseline ECOG status > 0 and was higher with increasing stage of disease (M1C>M1B>M1A>M0). The hazard ratio for OS corresponding to the median Cminss of 49.99 µg/mL was 0.745 relative to subjects in DTIC + placebo group. The probability of Grade 2+ or Grade 3+ GI, skin, liver and any irAEs also increases with Cminss. Prior anti-cancer therapy (including prior DTIC) or concomitant DTIC were the only significant covariates in the E-R irAE models. Conclusions: These model-based analyses suggest that higher Cminss of IPI appears to be associated with improved survival in pu-MEL (based on data from CA184024) and higher Cminss also appears to be associated with increased probability of irAEs in pu-MEL or pt-MEL.

5080 Background: In patients (pts) with castration-resistant prostate cancer and bone metastases (mCRPC), total ALP (tALP) has been shown to be a prognostic marker for overall survival (OS) (Cook 2006). Here the prognostic value of tALP and other baseline clinical variables in Ra-223 pts is presented, along with the initial results of an exploratory analysis of changes in tALP seen with Ra-223. Methods: Study population included 921 pts (intent-to-treat population) from the ALSYMPCA trial. The Cox proportional hazards model was used to evaluate the prognostic potential of tALP and other baseline variables (albumin, Hb, LDH, ECOG performance status, PSA, and age). Log transformation was done for baseline variables (tALP, PSA, and LDH) with heavily skewed distributions. Baseline variables were assessed for interaction with treatment. To determine changes in tALP from baseline at 12 wk, 708 pts who had tALP measurements at both baseline and 12 wk were included. Results: The baseline variables in the Table were significantly associated with OS. Hb was not a significant factor when adjusting for all other covariates and was therefore removed from the final Cox regression model. No significant treatment-by-covariate interactions were detected. After controlling for other variables, higher baseline tALP was significantly associated with an increased risk of death (p < 0.0001). At 12 wk, a decline in tALP relative to baseline was seen in 87% (433/497) of Ra-223 pts, compared to 23% (49/211) of placebo pts. The mean percentage change from baseline in tALP at 12 wk was a 32% decline for Ra-223 pts, in contrast to a 37% increase for placebo pts (p< 0.001). Conclusions: In mCRPC pts, higher baseline levels of tALP were associated with an increased risk of death. With the majority of Ra-223 pts experiencing a decline in tALP at 12 wk, and the marked mean percentage tALP decline in these pts, further analysis to determine a correlation between tALP dynamics and survival is warranted.

Abstract Research Aims: This study seeks to understand whether those with dementia experience higher risk of death, using data from the ASPREE (ASPirin in Reducing Events in the Elderly) clinical trial study. Methods: ASPREE was a primary intervention trial of low-dose aspirin among healthy older people. The Australian cohort included 16,703 dementia-free participants aged 70 years and over at enrolment. Participants were triggered for dementia adjudication if cognitive test results were poorer than expected, self-reporting dementia diagnosis or memory problems, or dementia medications were detected. Incidental dementia was adjudicated by an international adjudication committee using the Diagnostic and Statistical Manual for Mental Disorders (DSM-IV) criteria and results of a neuropsychological battery and functional measures with medical record substantiation. Statistical analyses used a cox proportional hazards model. Results: As previously reported, 1052 participants (5.5%) died during a median of 4.7 years of follow-up and 964 participants had a dementia trigger, of whom, 575 (60%) were adjucated as having dementia. Preliminary analyses has shown that the mortality rate was higher among participants with a dementia trigger, regardless of dementia adjudication outcome, than those without (15% vs 5%, Χ2 = 205, p &lt;.001). Conclusion: This study will provide important analyses of differences in the hazard ratio for mortality and causes of death among people with and without cognitive impairment and has important implications on service planning.

Objective Extent of resection (EOR) and Karnofsky Performance Status (KPS) are at odds in glioblastoma (GBM) surgery, that is, the anticipated postoperative disability limits the EOR. This study analyzes the correlation of different surgical modalities with the resulting physical status and survival of patients with GBM. Methods A total of 565 patients with primary GBM were operated on in a single institution between 2006 and 2014. Possible surgical modalities comprised supratotal resection (SLR), gross total resection (GTR; ≥ 95% by volume), tumor debulking (TDB; ≤ 95% by volume), and stereotactic biopsy (SB). Pre- and postoperative KPS before and up to 4 weeks after surgery as well as overall survival (OS) rate were determined retrospectively. Hazard ratio (HR) and 95% confidence intervals were calculated using a Cox proportional hazards model. Results Median postoperative KPS was ≥ 70, irrespective of surgical modality. Mean OS was 12.5 months. Multivariate analysis revealed age ≥ 70 years (HR: 1.93), preoperative KPS < 70 (HR: 2.15), and unmethylation in MGMT promoter (HR: 1.27) as independent factors for worse OS. Regarding surgical modality, SB was associated with the worst survival (HR: 2.3) followed by TDB (HR: 1.36). SLR was inferior to GTR (HR: 1.27). Conclusion Higher EOR in patients with GBM does not seem inevitably correlated with increasing functional impairment, but better survival, provided there is a balanced preoperative indication. Nevertheless, SLR does not seem to be superior to GTR. Whenever possible, maximal safe resection should be considered in patients with GBM, even if an EOR ≥ 95% is not possible.

Background: The natural history of vertebrobasilar artery (VBA) stenosis or occlusion remains understudied. Methods: Patients with diagnosis of ischemic stroke or transient ischemic attack (TIA) who were noted to have VBA stenosis based on computed tomography or magnetic resonance imaging or catheter-based angiogram were selected from Taiwan Stroke Registry. Cox proportional hazards model was used to determine the hazards ratio (HR) of recurrent stroke and death within 1 year of index event in various groups based on severity of VBA stenosis (none to mild: 0–49%; moderate to severe: 50–99%: occlusion: 100%) after adjusting for differences in demographic and clinical characteristics between groups at baseline evaluation. Results: None to mild or moderate to severe VBA stenosis was diagnosed in 6972 (66%) and 3,137 (29.8%) among 10,515 patients, respectively, and occlusion was identified in 406 (3.8%) patients. Comparing with patients who showed none to mild stenosis of VBA, there was a significantly higher risk of recurrent stroke (HR 1.21, 95% CI 1.01–1.45) among patients with moderate to severe VBA stenosis. There was a nonsignificantly higher risk of recurrent stroke (HR 1.49, 95% CI 0.99–2.22) and significantly higher risk of death (HR 2.21, 95% CI 1.72–2.83), among patients with VBA occlusion after adjustment of potential confounders. Conclusions: VBA stenosis or occlusion was relatively prevalent among patients with TIA or ischemic stroke and associated with higher risk of recurrent stroke and death in patients with ischemic stroke or TIA who had large artery atherosclerosis.

Summary: Clarithromycin can ameliorate symptoms and improve survival in disseminated Mycobacterium avium complex DMAC infection. Optimal combina tions of this drug with other agents remain unknown. Granulocyte colony stimulating factor G CSF is a cytokine that can improve phagocytosis of M. avium complex in vitro . We aim to determine if G CSF administration is associated with improved survival in patients with DMAC in a retrospective, cohort study. Case records from 1991 to 1995 of 91 patients with DMAC at Parkland Memorial Hospital were reviewed for date of initial DMAC diagnosis, baseline CD4 count, race, sex, antiretroviral use, G CSF use, therapy for DMAC clarithromycin, ethambutol, ciprofloxacin and rifabutin and date of death. Of 91 cases identified, 25 were treated with G CSF and 66 never received this drug. Baseline characteristics were similar in each group including CD4 count 40 cells mm 3 vs 33 cells mm 3, P =0.68 , clarithromycin use 18 patients vs 52 patients, P =0.90 , and antiretroviral use 20 patients vs 42 patients, P =0.21 . Subjects treated with G CSF lived longer than those who did not receive this drug 355 days vs 211 days, P 0.01 . In the subgroup treated with clarithromycin, G CSF was also associated with increased survival 377 days vs 252 days, P 0.01 . Cox proportional hazards model showed a decreased risk of death in patients treated with G CSF RH=0.22, P 0.01 , clarithromycin RH=0.13, P 0.01 and ethambutol RH=0.51, P =0.02 . Ciprofloxacin and rifabutin use did not influence survival. These data support the use of clarithromycin and ethambutol in the treatment of DMAC. Addition of G CSF to a regimen of clarithromycin and ethambutol may increase survival in DMAC and should be studied prospectively.

AbstractObjectiveWe investigated the relationship between the intake of fish and the risk of death from prostate cancer.DesignData were derived from a prospective cohort study in Japan. Fish consumption obtained from a baseline questionnaire was classified into the two categories of ‘low intake’ and ‘high intake’. The Cox proportional hazards model was used to estimate hazard ratios (HR) and 95 % confidence intervals.SubjectsData for 5589 men aged 30–79 years were analysed.ResultsA total of twenty-one prostate cancer deaths were observed during 75 072 person-years of follow-up. Mean age at baseline study of these twenty-one subjects was 67·7 years, ranging from 47 and 79 years old. Results showed a consistent inverse association of this cancer between the high v. low intake groups. The multivariate model adjusted for potential confounding factors and some other food items showed a HR of 0·12 (95 % CI 0·05, 0·32) for the high intake group of fish consumption.ConclusionsThese results support the hypothesis that a high intake of fish may decrease the risk of prostate cancer death. Given the paucity of studies examining the association between prostate cancer and fish consumption, particularly in Asian populations, these findings require confirmation in additional cohort studies.

Renal insufficiency (RI) is commonly seen in patients with hepatocellular carcinoma (HCC). The prognostic role of albumin-bilirubin (ALBI) grade in this special setting is unclear. We aimed to investigate the role of ALBI grade associated with the impact of RI on HCC. A prospective cohort of 3690 HCC patients between 2002 and 2016 were retrospectively analyzed. The Kaplan–Meier method and multivariate Cox proportional hazards model were used to determine survival and independent prognostic predictors. Of all patients, RI was an independent predictor associated with decreased survival. In multivariate Cox analysis for patients with RI, α-fetoprotein level ≥20 ng/mL, tumor size >3 cm, vascular invasion, distant metastasis, presence of ascites, performance status 1–2, performance status 3–4, and ALBI grade 2 and grade 3 were independent predictors of decreased survival (all p < 0.05). In subgroup analysis of patients with RI undergoing curative and non-curative treatments, the ALBI grade remained a significant prognostic predictor associated with decreased survival (p < 0.001). In summary, HCC patients with RI have decreased survival compared to those without RI. The ALBI grade can discriminate the survival in patients with RI independent of treatment strategy and is a feasible prognostic tool in this special patient population.
