e12030 Background: The role of post-mastectomy radiation therapy (PMRT) after neo-adjuvant chemotherapy (NCT) in those with T3N0 disease, younger age, and different tumor subtypes is unclear. Methods: We conducted a single institution, retrospective analysis of patients treated with NCT and mastectomy from 1985-2010. The primary objectives were to (1) assess the association between PMRT and long-term outcomes, and (2) describe outcomes and practice patterns based on tumor subtype, pathologic response, and age at diagnosis. Secondary objectives were to analyze the benefit of PMRT in those with favorable tumor subtypes, cT3N0 disease, and patients younger than 40. Log-rank test and Cox regression was used to test the association of predictors with outcomes. IRB approval was obtained. Results: Of 131 evaluable patients, 115 (88%) received PMRT. Mean±SD age was 48±10 years (range 29-79). Of patients <40 years of age (n=33) 88% received PMRT. At diagnosis, 69.5% were cT3; 53.5% were cN1; 12.3% were cT3N0. Seventy-eight percent of patients received anthracycline-based NCT and 52% received both anthracycline and taxane NCT. Twenty-eight percent of all patients achieved pCR. With a median f/u of 39 months (range 8-177), 30.5% of patients had a recurrence event (6.9% local, 5.3% nodal, 16.8% distant). Ten year OS and DFS for all patients were 56.7% (95% CI, 43.5-73.8) and 66.1% (95% CI, 52.3-83.5), respectively. Those with pCR had a non-significant trend toward better outcome, with 10 year OS=68.0% vs. 54.0% (p=0.7); DFS=70.2% vs. 65.2% (p=1.0). In the Cox regression analysis, pathologic T-stage, triple negative disease, and tumor grade were significantly associated with OS; triple negative disease was also predictive of DFS. Benefit of PMRT was not analyzable in cT3N0 due to small numbers. Conclusions: Most patients had PMRT, with outcomes on par with historical data. Most patients <40 years received PMRT, with no events for the non-PMRT cohort most likely due to selection bias. Unfavorable subgroups were not more likely to receive PMRT, but of those who did, only triple negative was predictive of outcome. A future non-PMRT matched cohort study is necessary to further elucidate the role of PMRT.

Abstract Background Fibromuscular dysplasia (FMD) is a non-atherosclerotic systemic arterial disease that is not infrequently discovered during kidney donor evaluation. Current guidelines do not provide recommendations regarding the use of kidneys from donors with FMD and there is a paucity of data on the outcomes of these donors. Methods The Renal and Lung Living Donor Evaluation (RELIVE) study addressed long-term outcomes of 8922 kidney donors who donated between 1963 and 2007. We compared the development of hypertension, cardiovascular disease (CVD), proteinuria and reduced estimated glomerular filtration rate (eGFR) in 113 kidney donors with FMD discovered during donor evaluation versus 452 propensity score matched donors without FMD. Outcomes modeling with logistic and Cox regression analysis and Kaplan–Meier statistics were performed. Results Donors with FMD were older (51 versus 39 years), were more likely to be women (80% versus 56%) and had a higher systolic blood pressure at donation (124.7 versus 121.3 mmHg) (P &lt; 0.05 for all). After a mean ± standard deviation follow-up of 15.5 ± 8.9 years, a similar proportion of donors with and without FMD were alive, and developed hypertension (22.2% versus 19.8%), proteinuria (20.6% versus 13.7%) and CVD (13.3% versus 13.5%). No donor with FMD developed an eGFR &lt;30 mL/min/1.73 m2 or end-stage kidney disease. The multivariable risk of mortality, CVD and renal outcomes in donors with FMD was not elevated. Conclusions Kidney donors with FMD appear to do well, do not appear to incur increased risks of hypertension, proteinuria, CVD or reduced eGFR, and perhaps carefully selected candidates with FMD can safely donate as long as involvement of other vascular beds is ruled out.

Long Term Mortality

Abstract Background Late left ventricular remodeling (LLVR) after the index acute myocardial infarction (AMI) is a common complication, and is associated with poor outcome. However, the optimal definition of LLVR has been debated because of its different incidence and influence on prognosis. At present, there are limited data regarding the influence of different LLVR definitions on long-term outcomes in AMI patients undergoing percutaneous coronary intervention (PCI). Purpose To explore the impact of different definitions of LLVR on long-term mortality, re-hospitalization or an urgent visit for heart failure, and identify which definition was more suitable for predicting long-term outcomes in AMI patients undergoing PCI. Methods We prospectively observed 460 consenting first-time AMI patients undergoing PCI from January 2012 to December 2018. LLVR was defined as a ≥20% increase in left ventricular end-diastolic volume (LVEDV), or a &gt;15% increase in left ventricular end-systolic volume (LVESV) from the initial presentation to the 3–12 months follow-up, or left ventricular ejection fraction (LVEF) &lt;50% at follow up. These parameters of the cardiac structure and function were measuring through the thoracic echocardiography. The association of LLVR with long-term prognosis was investigated by Cox regression analysis. Results The incidence rate of LLVR was 38.1% (n=171). The occurrence of LLVR according to LVESV, LVEDV and LVEF definition were 26.6% (n=117), 31.9% (n=142) and 11.5% (n=51), respectively. During a median follow-up of 2 years, after adjusting other potential risk factors, multivariable Cox regression analysis revealed LLVR of LVESV definition [hazard ratio (HR): 2.50, 95% confidence interval (CI): 1.19–5.22, P=0.015], LLVR of LVEF definition (HR: 16.46, 95% CI: 6.96–38.92, P&lt;0.001) and LLVR of Mix definition (HR: 5.86, 95% CI: 2.45–14.04, P&lt;0.001) were risk factors for long-term mortality, re-hospitalization or an urgent visit for heart failure. But only LLVR of LVEF definition was a risk predictor for long-term mortality (HR: 6.84, 95% CI: 1.98–23.65, P=0.002). Conclusions LLVR defined by LVESV or LVEF may be more suitable for predicting long-term mortality, re-hospitalization or an urgent visit for heart failure in AMI patients undergoing PCI. However, only LLVR defined by LVEF could be used for predicting long-term mortality. FUNDunding Acknowledgement Type of funding sources: None.

Abstract Abstract 2929 Background: Two pivotal phase 3 trials (MM-009 and MM-010) randomized 704 pts to assess Len+Dex vs placebo plus dexamethasone (Dex) in RRMM. The results demonstrated the significant overall survival (OS) benefit of Len+Dex vs Dex (38.0 vs 31.6 mos; p =.045) despite crossover of 48% of Dex pts to the Len+Dex arm at unblinding or progression (Dimopoulos MA et al. Leukemia 2009;23 :2147-52). This is an analysis of the long-term outcomes and safety of continuous Len+Dex treatment. Methods: This retrospective analysis pooled pts treated with Len+Dex in MM-009 and MM-010, with a median follow-up of 48 mos for surviving pts. A subset of pts with progression-free survival (PFS) of ≥ 2 yrs was selected. Prognostic factors for PFS within this subgroup of pts were identified by incorporating all baseline covariates with a univariate p <.15 into multivariate Cox regression analyses, and all possible models were fitted using SAS 9.2. Adverse event (AE) management and dosing for pts with PFS ≥ 2 yrs was compared with that for all pts treated with Len+Dex in order to evaluate if differences in pt management could contribute to better clinical outcomes. Incidence rates for AEs were calculated using person-yrs of follow-up. Data from pts who received Len+Dex in MM-009 (up to July 23, 2008) and MM-010 (up to March 2, 2008) were included in this analysis. Results: Among all pts treated with Len+Dex (N = 353), a total of 64 pts (18%) achieved PFS ≥ 2 yrs. For these 64 pts, median age was 61 yrs (range 33–81 yrs), 48% received > 1 prior therapy, and 57% had β2-microglobulin levels of ≥ 2.5mg/L. All these pts achieved a ≥ partial response (PR), including 67% with a ≥ very good PR and 50% with a complete response. Median time to first response was 2.8 mos (range 1.9–18.2 mos) which is comparable to that of all pts treated with Len+Dex. Median duration of response was not reached vs 15.5 mos, respectively. With median follow-up of 49 mos, the 3-yr OS is 94% (95% confidence interval [CI] 88.06–99.94). In a multivariate Cox regression analysis, shorter PFS was predicted with higher baseline β2-microglobulin level (hazard ratio [HR] 1.07; 95% CI 1.02–1.12) and lower hemoglobin (HR 0.91; 95% CI 0.84–0.99), as well as a higher number of prior therapies (HR 1.18; 95% CI 1.02–1.37). The median duration of treatment was longer among pts with PFS ≥ 2 yrs vs all pts treated with Len+Dex (46.2 mos [range 11.3–58.3] vs 9.8 mos [range 3.8–24], respectively). A higher proportion of these pts had a dose reduction within 12 mos after start of therapy vs all pts treated with Len+Dex (57% vs 24%, respectively). Dex dose was reduced in 27% of pts with PFS ≥ 2 yrs. Among pts without Len dose reduction, 31% had Dex dose reduction within the first 4 cycles. Granulocyte colony-stimulating factor was administered for the management of neutropenia in 39% of pts with PFS ≥ 2 yrs vs 25% of all pts treated with Len+Dex. Low discontinuation rates due to AEs were observed in both groups (12.5% vs 18.7%, respectively). The incidence rates per 100 person-yrs for grade 3–4 AEs among pts with PFS ≥ 2 yrs vs all pts treated with Len+Dex (N = 353) were, respectively: neutropenia (14.9 vs 29), febrile neutropenia (0.9 vs 2.3), thrombocytopenia (2.6 vs 10.2), anemia (4.4 vs 9.5), infection (11.8 vs 20.9), deep vein thrombosis/pulmonary embolism (2.2 vs 8.9), fatigue (2.2 vs 5.5), neuropathy (1.8 vs 3.4), and gastrointestinal disorders (5.3 vs 9.7). The incidence rates per 100 person-yrs for second primary malignancies (SPMs) were similar to that of all pts treated with Len+Dex, respectively: myelodysplastic syndromes (0 vs 0.4), solid tumor (1.8 vs 1.3), and non-melanoma skin cancer (2.3 vs 2.4). These rates are comparable to those expected in people aged > 50 yrs generally (1.4 per 100 person-yrs) (Altekruse SF et al. SEER Cancer Statistics Review, 1975–2007). Conclusions: Long-term continuous therapy with Len+Dex has demonstrated efficacy and is generally well tolerated in pts with RRMM. Overall, 18% of patients treated with Len+Dex achieve a PFS of > 2 yrs. No increase in SPMs was observed with long term Len+Dex therapy. With appropriate AE management, the incidence rates of grade 3–4 AEs remain low. This analysis demonstrates the value of AE management and the need for appropriate dose-adjustment to maintain tolerability, allowing pts to remain on therapy for maximal benefit.

4500 Background: The IGFR pathway is activated in pancreatic cancer and may result in aggressive disease course. The study of single nucleotide polymorphisms (SNPs) involved in this pathway may provide prognostic information and predict response to IGFR directed agents. We investigated IGFR pathway SNPs in patients with LAPC. Methods: We evaluated 39 SNPs from 7 candidate genes in the IGFR pathway (IGF1R, IGF2R, IGF1, IGF2, IRS1, IRS2, IGFBP3) in 105 LAPC patients. DNA extraction from whole blood was performed using the Qiagen Flexigene DNA and Promega Maxwell 16 kits. Genotyping was performed using the Sequenom method. Overall survival was measured from date of diagnosis to date of death or last follow-up. Kaplan-Meier plot, log-rank test, and Cox regression were used to compare survival of patients according to genotype corrected for previously identified prognostic factors, including induction chemotherapy, CA 19–9, albumin, LDH, hemoglobin and Karnofsky performance status (KPS). Results: Median survival time (MST) was 15 months (95% CI 13.3–16.7). Induction chemotherapy, LDH, CA 19–9 level, hemoglobin, and KPS were not significantly associated with survival. Serum albumin and three SNPs of the IGF pathway (IGF1R IVS20–3431A>G, IRS1 G971R, and IGF2 *4352A>G) were significantly associated with prognosis ( Table ). Two of the three genotypes remained as significant predictors for survival in Cox regression analysis when adjusted for clinical factors. A significant combined genotype effect was observed wherein patients with all three deleterious alleles had significantly worse survival than those with only two or one (10 vs. 16.3 vs. 21.3 months, p< 0.0001). Conclusions: These data suggest that SNPs in the IGFR pathway genes may have prognostic value for LAPC patients. This information may identify population subgroups that could benefit from IGFR-targeted agents. [Table: see text] No significant financial relationships to disclose.

Abstract Background: Laparoscopic surgery has been widely accepted to treat early-stage gastric cancer. However, it is still controversial to perform laparoscopic gastrectomy plus D2 lymphadenectomy for locally advanced gastric cancer. We performed the present study to compare the long-term outcomes of patients after laparoscopic or open gastrectomy plus D2 lymphadenectomy . Methods: The clinicopathological data of 182 gastric cancer patients receiving gastrectomy plus D2 lymphadenectomy between January 2011 and December 2015 at Shenzhen Traditional Chinese Medicine Hospital were retrospectively retrieved. The overall survival (OS) and disease-free survival (DFS) of these 182 patients were compared.Results: On the whole, OS (P=0.789) and DFS (P=0.672) of patients receiving laparoscopic gastrectomy plus D2 lymphadenectomy were not significantly different from those of patients receiving open surgery. For stage I patients, laparoscopic gastrectomy plus D2 lymphadenectomy was not significantly different from open surgery in terms of OS (P=0.573) and DFS (P=0.157). Similarly, for stage II patients, laparoscopic gastrectomy plus D2 lymphadenectomy was not significantly different from open surgery in terms of OS (P=0.567) and DFS (P=0.830). For stage III patients, laparoscopic gastrectomy plus D2 lymphadenectomy was not significantly different from open surgery in terms of OS (P=0.773) and DFS (P=0.404). Laparoscopic or open gastrectomy plus D2 lymphadenectomy was not proven by Cox regression analysis to be an independent prognostic factor for OS and DFS.Conclusions: For patients with gastric cancer, laparoscopic gastrectomy plus D2 lymphadenectomy was not inferior to open surgery in terms of long-term outcomes.

7017 Background: We previously reported the superiority of combined chemo-radiotherapy (CRT) over RT alone in elderly pts with locally advanced NSCLC (Atagi et al. ECCO2011). One and a half years follow-up data from last accrual are presented. Methods: Pts older than 70 years with unresectable stage III NSCLC were randomized to either RT alone (RT arm), a total dose of 60 Gy, or CRT arm including the same RT plus concurrent chemotherapy with carboplatin 30 mg/m2/day, 5 days/week × 20 days. The primary endpoint was overall survival (OS). The planned sample size was 100 pts in each arm with one-sided alpha of 5% and 80% power to detect a difference in median survival time (MST) from 10 months in RT arm to 15 months in CRT arm. Results: Between Sep 2003 and May 2010, 200 pts were randomized. Baseline characteristics were similar in the RT (n=100) vs CRT (n=100) arms: median age, 77 vs 77 years; stage IIIB (n), 46 vs 49; PS 0/1/2 (n), 41/55/4 vs 41/56/3. The second planned interim analysis was performed 10 months after the completion of accrual. In accordance with the pre-specified stopping rule, the JCOG Data and Safety Monitoring Committee recommended early publication of this trial because of the difference in OS favoring the CRT arm. In the updated analysis, OS was better in the CRT arm than the RT arm (HR = .64, 95% CI = .46-.89, one-sided p = .0033 by stratified log-rank test). In each arm (RT/CRT), MST was 16.5 mo/22.4 mo with 3-year OS of 14.3%/34.6%, response rate of 44.9%/54.6% (p=.201) and median progression-free survival of 6.9 mo/8.9 mo (p=.003). Gr 3/4 toxicities were (RT/CRT): neutropenia 0%/57.3%, infection 4.1%/12.5%, dysphagia 0%/1.0%, late RT toxicities 7.4%/7.5%. The pattern of relapse site and post-protocol treatment were almost similar between the arms. Even after an adjustment by the Cox regression analysis with six variables [stage, PS, sex, age, histology, smoking status], CRT arm showed better survival (HR=.71, p=.038). Conclusions: The CRT using daily carboplatin is considered to be the standard treatment for elderly pts with locally advanced NSCLC.
