Abstract Abstract 2891 Poster Board II-867 Thalidomide maintenance therapy after completion of induction therapy plus ASCT and also after conventional therapy yielded conflicting results with some trials showing improvement in overall survival and others not. This study evaluates the efficacy of Thalidomide plus Interferon a2b (Thal-IFN) in comparison to interferon a2b (IFN) as maintenance therapy in elderly pts with multiple myeloma. For induction therapy, 289 pts had been randomized to either Thalidomide-Dexamethasone or to Melphalan-Prednisolone; results of this part of the study had been reported previously (BLOOD, 113, 3435-3442, 2009). 137 pts who had completed 9 cycles of induction therapy and had achieved stable disease or better were eligible for maintenance treatment, and 128 (median age 72 years, range 54 - 86 years) had finally been randomized to either Thal (starting dose: 200mg/day) in combination with IFN-a2b (Schering-Plough, 3 Mega U, TIW) or IFN a2b (IFN) at the same dose/schedule only. All pts were scheduled for zoledronate 4mg, q 4 weeks. Median follow up from randomization to maintenance: 35 mos. Median duration of maintenance therapy: 13.2 mos and 8.3 mos for pts randomized to Thal-IFN or to IFN, respectively (logrank test p=0.20). Maintenance therapy with Thal-IFN resulted in an improvement in the depth of response from PR to VGPR or CR in 5 (8%) and with IFN in 2 (3%) pts, respectively. Progression-free survival (PFS) was significantly longer in the Thal-IFN (27.7 mos) compared to the IFN only maintenance group (13.2 mos), (HR, 0.55; 95% 95% CI, 0.36-0.86; log-rank test, p=0.0068). Analysis of PFS by either Thal-Dex or MP induction therapy showed a significantly shorter PFS in pts started on Thal-Dex and subsequently randomized to IFN maintenance only (7.8 mos, log-rank test, p=0.037). PFS was 27.7 mos in pts started on Thal-Dex followed by Thal-IFN, 20.2 mos in those with MP induction therapy followed by IFN, and 27.6 mos in pts with Thal-IFN maintenance after MP induction therapy. Overall survival (OS) was similar in both groups (Thal-IFN 52.6 mos and IFN 51.4 mos, HR: 0.93, 95% CI: 0.53-1.66, log-rank test; p=0.81). OS by induction therapy did not vary significantly between the four treatment groups (logrank test, p=0.99). No significant difference in OS was seen between pts younger than 75 years and those aged 75 years or older (logrank test, p=0.39). Survival after progression of disease tended to be longer in pts who received IFN maintenance therapy only compared to those started on Thal-IFN (HR: 1.75, 95% CI, 0.97 – 3.14, logrank test: 0.056), while OS was similar between both groups when analyzed from termination of maintenance therapy (HR: 1.20, 95% CI, 0.65 – 2.20, log rang test 0.57). Baseline scores of the EORTC QLQ C30 items general health (Thal-IFN, mean 56; IFN, mean 59) and overall quality of life (Thal-IFN, mean 58; IFN, mean 60) were markedly below the score obtained in an healthy population (mean 75.3 and 73.3 respectively), but did neither differ at baseline between both groups nor did they vary significantly during the course of the maintenance (statistics will be provided). Cytogenetic data were available in 66 pts. PFS tended to be longer in pts with adverse FISH findings [t (4; 14), t (14; 20) Del 17p and abnormalities of 1q21] compared to the standard risk group, but differences were not significant (median: 31.5 vs. 21.6 mos, HR: 1.69, 95% CI, 0.13 – 3.07, log-rank test 0.084). The median of OS was 72.3 mos in those with standard risk and 39.6 mos in those with high risk features (HR: 1.94, 95% CI 0.91-4.13, log rank test: 0.082). In multivariate analysis (Cox model) only Thal-IFN maintenance therapy was shown to correlate significantly with PFS (HR: 0.61, 95% CI: 0.39-0.89, p=0.04) while for poor performance status, low hemoglobin, and low albumin a statistically non-significant correlation with survival was noted. Hematologic toxicity was similar between both groups. Pts on Thal-IFN maintenance experienced significantly more neuropathy (p=0.0024), constipation (p=0.0007) and skin toxicity (p=0.0063) and increase in renal impairment (p=0.037). In addition, there was a tendency for more dyspnea (p=0.40) and more fatigue (p=0.11) in pts on Thal-IFN maintenance therapy. Other non-hematological toxicities were similarly distributed in both therapy arms. In conclusion, Thal-IFN maintenance therapy resulted in increased PFS compared IFN maintenance treatment only, but OS was similar between both groups.

The standard of care for patients with newly diagnosed multiple myeloma who are transplant eligible is induction therapy followed by conditioning with high dose melphalan and autologous hematopoietic cell transplant (HCT). While the value of a single HCT (S-HCT) is established in standard-risk myeloma (SRM), there is controversy about whether tandem transplantation would improve outcomes such as progression-free survival (PFS) or overall survival (OS) in high-risk myeloma (HRM) patients. In this IRB approved retrospective study, the records of 343 multiple myeloma patients, who were referred by community oncologists and underwent HCT at Virginia Commonwealth University from 2008 to 2015, were reviewed. Patients were classified into different disease risk groups and OS and PFS determined. HRM was defined as including at least one of the following prognostic factors at diagnosis: t(4;14), t(14;16), t(14;20), del17p13, or gain of 1q by FISH; del 13 or aneuploidy by karyotyping; and ISS stage 3; patients without these features and with standard risk attributes were classified as SRM, while any patients with missing attribute information were classified as having undetermined risk myeloma (URM). In the study population, there were 135 SRM, 100 HRM, and 104 URM patients. Median age of the entire cohort was 60 years (76-34). The patients underwent hematopoietic cell mobilization and collection with filgrastim ± plerixafor and were conditioned with high-dose Melphalan (140-200 mg/m2). When possible, patients with SRM underwent single HCT (S-HCT) and those with HRM, tandem HCT (T-HCT) based on risk classification, response to prior therapy, insurance mandate and patient/physician preference. In those undergoing T-HCT, the median time to second HCT was 141 days. Evaluating the entire study population, and comparing patients who underwent a T-HCT (median follow up 82 mo.) vs. a S-HCT (85 mo.), there was no significant difference in OS (adjusted HR 1.1, 95% CI: 0.7-1.8; Cox proportional hazard model, adjusted for age, gender and risk group) (Figure 1) and PFS (HR 0.9, 95% CI: 0.6-1.2) between these two treatment groups. Of the 135 SRM patients, 20 underwent T-HCT; there was no significant difference in OS (HR = 1.2, 95% CI 0.5-2.9) and PFS (HR = 0.9, 95% CI = 0.5-1.7) in these patients compared to those undergoing S-SCT. Of the 100 HRM patients, 46 underwent T-HCT (P <0.01 c/w SRM & URM for T-HCT assignment). Again, there was no significant difference observed in OS (HR = 1.3, 95% CI = 0.7 - 2.5) (Figure 2) and PFS (HR = 1.0, 95% CI = 0.6 - 1.8) in the T-HCT recipients as compared to S-SCT amongst the HRM patients. Similar outcomes were observed in the URM patients. There were no differences observed between S-HCT and T-HCT outcomes in patients with deletion of chromosome 17p or in those with ISS stage 3 disease in OS (HR = 1.7, 95% CI = 0.8 - 3.8) and PFS (HR = 1.0, 95% CI: 0.5, 1.9). Overall, HRM patients had a trend for worse, albeit not significantly different, OS (HR 1.4, 95% CI: 0.9-2.2), as well as PFS (HR 1.1, 95% CI 0.7-1.6) compared to SRM; URM demonstrated a similar trend vis a vis SRM. This retrospective review of survival in SRM and HRM transplanted at a single center demonstrates that in the era of induction and maintenance therapy with novel agents, tandem transplantation does not improve OS or PFS in either SRM or HRM patients compared to a single transplant. Standard of care for newly diagnosed multiple myeloma patients who are transplant eligible should remain induction therapy with novel agents followed by single autologous HCT and maintenance therapy. Disclosures No relevant conflicts of interest to declare.

Background/Aim: Here, we investigated whether bortezomib as a maintenance therapy affected outcomes in transplant-ineligible patients with multiple myeloma (MM). Patients and Methods: Following induction therapy with bortezomib, maintenance therapy with bortezomib (1.3 mg/m2) and dexamethasone (20 mg) was administered once or twice every 4 weeks until disease progression. The endpoints of this study were time to next treatment and overall survival. Results: Seventy-six newly diagnosed, transplant-ineligible patients were treated with a bortezomib-based regimen; 28 discontinued induction therapy, 27 did not receive maintenance therapy after induction therapy (the non-maintenance group), and 21 did (the maintenance group). In the three groups, the median times to the next required treatment were 3, 14, and 37 months, respectively. The 3-year overall survival rates were 55%, 69%, and 85%, respectively. There were no significant differences in patient characteristics between the non-maintenance and maintenance groups, except for poorer estimated glomerular filtration rates in the maintenance group. Conclusion: Bortezomib maintenance therapy may be a useful option for transplant-ineligible patients with MM.

Plasma Cell Leukaemia

Abstract Introduction: Primary plasma cell leukaemia (PCL) is a rare disorder representing less than 5% of malignant plasma cell disease and is associated with a poor prognosis with median survivals in PCL reported at 8 to 12 months, significantly shorter than for Multiple Myeloma even when the comparison is adjusted to compare only with Multiple Myeloma of high tumour mass. Treatment of PCL with alkylating agent-based therapy is ineffective and while polychemotherapy may offer improved survival, results remain disappointing with a few exceptions. Autologous transplantation is now being used widely in the treatment of these patients and this report summarises the European Blood and Marrow Transplant (EBMT) experience of this disorder. Patients and Methods: A retrospective study was carried out with 20844 patients with common type multiple myeloma (58% IgG, 21% IgA and 19% light chain types only) and 272 patients with primary plasma cell leukaemia who underwent first autologous transplantation between 1980 and 2006. All patients were reported to the EBMT registry using MED-A (limited data set) or MED-B (more extensive data set) forms. All autografted patients were included in the study regardless of the availability of complete MED-A or MED-B data. The proportion of patients that could be evaluated for each parameter was noted and the number of evaluable patients included in the result. Comparisons between the two groups were made using Chi-squared test for categorical data and the Mann-Whitney test for continuous data. Overall Survival and Progression-Free Survival were calculated using the Kaplan-Meier method and comparisons were made using the Log-Rank test. Relapse/Progression and Death without relapse or progression probabilities were computed by the proper non-parametric estimator for outcomes with competing risks and compared by the Gray test. Results: There were no significant differences in age and gender of the PCL and myeloma groups. Calcium and albumin were also not significantly different, however, haemoglobin was significantly lower in the PCL group (11g/dl versus 9g/dl - P=0.000) while creatinine was significantly higher in the PCL group - 92 micro mol/l versus 122 micro mol/l - P=0.000). B2 microglobulin was significantly higher in the PCL group which tends to be diagnosed with a more advanced disease. There was no difference in the type of graft used or in the use of total body irradiation but the PCL group were transplanted within a shorter time from diagnosis (6.0 v 7.7 months - P=0.000). While there was no significant difference in engraftment, PCL patients were more likely than myeloma patients to enter CR post-autologous transplantation. Despite this, overall survival for the PCL patients was greatly inferior to the myeloma patients - 62.3 months (CI 60.4–64.3) versus 25.7 months (CI 19.5–31.9 - P=0.000). Poor survival is accounted for by an increase in relapse-related mortality and post-transplant responses of short duration. Conclusion: This is the largest study of plasma cell leukaemia patients ever reported. Our data shows an improved outcome for these patients with use of autologous transplantation but undoubtedly this transplant group represents the fittest of such patients and their outcome is still greatly inferior to comparable myeloma patients.

e15756 Background: Preclinical studies have shown that calcium channel blockers (CCB) may potentiate anticancer effect of chemotherapy via intra-cellular drug accumulation. Gemcitabine-based chemotherapy is commonly used in pancreatic cancer (PC) patients. The aim of this study was to determine whether CCB may affect overall survival (OS) in PC patients receiving gemcitabine-based chemotherapy. Methods: The retrospective cohort of PC patients treated with gemcitabine between 2007 and 2016 was identified in the Polish National Health Fund databases. Electronic records of prescriptions were searched to identify in this cohort patients receiving CCB (amlodipine, nitrendipine, felodipine, lacidipine). The primary endpoint was OS and it was determined by Kaplan-Meier methods and compared by the log-rank test. Results: In total 4628 PC patients treated with gemcitabine (median OS 7.7 months; 95% CI: 7.4-7.9) were identified. Among these 380 patients were prescribed any CCB. There was a significant difference (p < 0.001) in median OS between patients prescribed CCB (n = 380; OS 9.3 months; 95% CI: 7.8-11.0) and those who did not (n = 4214; OS 7.6 months; 95% CI: 7.3-7.8) with hazard ratio for death 0.70 (95% CI: 0.62-0.79). Notably, the survival curves tended to flatten in CCB group, with 24% of patients alive at 2 years (95% CI: 20-29%) and 15% alive at 5 years (95% CI: 11-19%), compared with 11% (95% CI: 10-12%) and 4% (95% CI: 4-5%) in controls respectively. Conclusions: The use of CCB in PC patients receiving gemcitabine-based chemotherapy was associated with improved OS. Further validation is needed to evaluate effectiveness of CCB-gemcitabine combinations in the management of PC.

Abstract We retrospectively reviewed all patients receiving bortezomib, lenalidomide and dexamethasone induction followed by autologous stem cell transplantation (ASCT) within 12 months of diagnosis for multiple myeloma at the Mayo Clinic. 243 patients treated between January 2010 and April of 2017 were included in the study. Median age was 61 (interquartile range, 55-67) with 62% of patients being male. High risk cytogenetic abnormalities (HRA) were present in 34% of patients. 166 (68%) patients received some form of maintenance/other therapy post transplant (no maintenance (NM, n=77), lenalidomide maintenance (LM, n=108), bortezomib maintenance (BM, n=39) and other therapy (OT, n=19)). Overall response rate was 99% with complete response (CR) rate of 42% and 62% at day 100 and time of best response post transplant respectively. The four cohorts categorized by post transplant therapy were well matched for age, gender and ISS stage. HRA were more common amongst patients receiving bortezomib maintenance or other therapy post transplant (NM 18% vs LM 22% vs BM 68% vs OT 79%, p<0.0001). Two year and five year overall survival rates were 90% and 67% respectively with an estimated median overall survival (OS) and progression free survival (PFS) of 96 months and 28 months respectively for the whole cohort. OS was not significantly different when stratified by post-transplant therapy (Median OS 96 months for NM vs not reached for LM vs 62 months for BM vs not reached for OT, p=0.61), however post-transplant therapy was predictive of PFS (median PFS 23 months for NM vs 34 months for LM vs 28 months for BM vs 76 months for OT, p=0.01). High risk cytogenetics was associated with a worse OS but not PFS when compared to patients with standard risk (median OS: not reached for standard risk vs 60 months for HRA, p=0.0006; median PFS: 27 months for standard risk vs 22 months for HRA, p=0.70). In patients that did not receive maintenance therapy presence of HRA was a strong predictor of OS and PFS (median OS: not reached for standard risk vs 36 months for HRA, p<0.0001; median PFS: 24 months for standard risk vs 7 months for HRA, p<0.0001). Patients receiving maintenance therapy appeared to have a similar PFS and OS irrespective of cytogenetics (median OS: not reached for standard risk vs 62 months for HRA, p=0.14; median PFS: 35 months for standard risk vs 34 months for HRA, p=0.79).On multivariable analysis ISS stage III and achieving CR/stringent CR predicted PFS whilst the only independent predictors of OS were presence of HRA and achieving CR/stringent CR. The combination of bortezomib, lenalidomide and dexamethasone followed by ASCT is a highly effective regimen producing deep and durable responses in many patients. Maintenance therapy in this cohort may overcome the poor prognostic impact of high risk cytogenetic abnormalities. Table Table.

Adenocarcinoma Of The Pancreas

359 Background: The role of adjuvant chemotherapy in pancreas cancer has been well established. The role of radiation therapy however remains controversial. The ESPAC-1 study showed a possible deleterious effect for radiation on survival of patients with resected pancreas cancer, although the study was limited by lack of compliance and quality control. Methods: We performed a retrospective analysis of patients who underwent curative resection of their cancer of the pancreas over the last 2 decades at the Ohio State University. 333 patients with adenocarcinoma of the pancreas were identified from our database and 148 subjects were found with complete treatment information available. Thirty patients had no treatment after resection. Log-rank test was used to compare the overall survival (OS) of two groups of patients: treated with chemotherapy (C, N=68) or fluoropyrimidine-based chemoradiation (CRT, N=50). Demographics of the CT and CRT groups were balanced. Patient characteristics including age, sex, tumor size, tumor location, tumor grade, nodal status, margins (R0 vs. R1) and number of hospitalizations within a six-month period of discharge from the hospital after surgery were compared across all groups. The effect of these variables on OS was assessed using log-rank test. Results: The mOS for C (21.5 months, 95% CI; 13.5, 24.6) and CRT (16.8 months, 95% CI; 13.9, 23.1) were similar. There was no statistically significant difference observed for C vs. CRT (p>0.8). Out of all the characteristic variables tested (N= 148), only the presence of at least one positive lymph node vs. none had a statistically significant negative effect on survival (mOS of 12.20 months vs. 23.10 months; p=0.0053). Conclusions: In patients with resected adenocarcinoma of the pancreas, the addition of radiation does not seem to add benefit. The presence of positive lymph nodes is an adverse prognostic factor on overall survival.

Abstract Introduction A phase 2 dose escalation trial of Carfilzomib in combination with Thalidomide and Dexamethasone (KTd) for induction and consolidation in newly diagnosed, transplant-eligible patients with multiple myeloma (MM). We report the results of 4 dose levels. Methods In this multicenter, open-label, phase 2 trial, transplant-eligible patients aged between 18 and 65 years with previously untreated symptomatic MM were included. Patients were treated with 4 cycles of escalating dose of Carfilzomib + fixed-dose thalidomide and dexamethasone (KTd) for induction therapy. The dose of Carfilzomib was 20 mg/m2 i.v. on days 1, 2 followed by 27 mg/m2 on days 8, 9, 15, 16 of cycle 1 and on days 1, 2, 8, 9, 15 and 16 of cycles 2 to 4. Thalidomide dose was 200 mg orally on days 1 through 28 and Dexamethasone 40 mg orally on days 1, 8, 15 and 22. Carfilzomib was escalated to 20/36 mg/m2 in cohort 2, to 20/45 mg/m2 in cohort 3 and to 20/56 mg/m2 in cohort 4. Induction was followed by stem cell harvest after Cyclophosphamide priming (2 to 4 mg/m2) and G-CSF. Hereafter patients received high-dose Melphalan (HDM, 200mg/m2) and autologous stem cell transplantation followed by consolidation treatment with 4 cycles of KTd in the same schedule except a lower dose of Thalidomide (50mg). The primary endpoint was response after induction therapy and overall, specifically complete response (CR) and very good partial response (VGPR). Secondary endpoints were safety, progression-free survival (PFS) and overall survival (OS). Results All 111 patients with a median follow-up of 55, 42, 35 and 28 months, in cohorts 1 to 4, respectively were included in the analysis. Median age was 58 years. ISS stages I/II/III were 41%/34%/23%, respectively, R-ISS stages I/II/III/unknown were 23%/59%/9%/9%, respectively. Of 111 patients, 9 patients stopped treatment during/after induction, 8 patients after cyclophosphamide priming or HDM and 9 patients during consolidation because of toxicity (n=9), non-eligibility for further treatment (n=6), progression (n=5), refusal (n=2) or other reasons (n=4). Overall response rate for all cohorts was 95%. Response after induction was CR/sCR in 18% of patients, ≥ VGPR in 66% of patients, ≥ PR in 94% of patients. After HDM the CR/sCR rate increased to 31% and after consolidation to 64%. Responses between cohorts were in general comparable. See Table 1. Response based on risk status by ISS/FISH in either cohort and accumulated did not show a difference in CR/sCR rate after consolidation between standard-risk (67%) and high risk defined as t(4;14) and/or del17p and/or add1q and/or ISS3 (60%). OS at 30 months was comparable between standard risk and high risk, 91% versus 90%. PFS at 30 months for standard risk and high risk was 79% and 62%, logrank p=0.02 (HR=2.3, 95% CI=1.1-4.5). PFS at 30 months per cohort was 70% (95% CI, 55% to 81%), 70% (95% CI, 45% to 85%), 80% (95% CI, 56% to 92%) and 62% (95% CI, 32% to 82%) in cohorts 1,2, 3 and 4, respectively, and 71% (95% CI, 61% to 79%) in all patients. OS at 30 months per cohort was 90% (95% CI, 77% to 96%), 90% (95% CI, 66% to 97%), 95% (95% CI, 71% to 99%) and 88% (95% CI, 58% to 97%) respectively, and 91% (95% CI, 83% to 95%) in all patients. Gene expression profiling using the Affymetrix U133 Plus 2.0 GeneChips was performed on purified tumor cells for 49 patients. Using the prognostic classifier EMC92 a high-risk group of patients (16%) was identified versus standard risk (in terms of OS: logrank p=0.06 (HR=3.7, 95% CI=0.8-16.8), and in terms of PFS: logrank p=0.14 (HR=2.1, 95% CI=0.8-6.0)). Safety analysis for all 111 patients showed non-hematological grade 3 and 4 toxicity, mainly respiratory disorders (in 15%), GI disorders (13%) and skin lesions (10%). Toxicity between cohorts did not show a significant difference. Cardiac adverse events were limited and included heart failure (n=2 at 27 mg/m2), hypertension (n=2) and chest pain (n=1 at 45mg/m2). Conclusion Carfilzomib, thalidomide, dexamethasone (KTd) is an effective regimen, with increasing CR percentages following KTd consolidation. With escalated doses of Carfilzomib responses and toxicity were comparable to standard dose of 27 mg/m2.

Abstract Background: Limited data exists regarding the characteristics and outcomes of adolescents and young adults (AYAs) with acute myeloid leukemia (AML) which are largely under-represented in both pediatric and adult trials. We sought to compare the characteristics and outcomes of AYAs with AML using a large population based registry in the United States. Methods: We utilized Surveillance Epidemiology and End Results (SEER)-18 registry to identify all pediatric (0-18 years) and AYA (age 19-30 years) patients diagnosed with AML using appropriate histology codes based on the International Classification of Diseases for Oncology, 3rd version. Patients with acute promyelocytic leukemia (APL) were excluded from all analysis. Survival statistics were computed for each group using actuarial (Kaplan-Meier method) and compared using Z test for comparison of population proportions. Early mortality, defined as mortality within 1 month of diagnosis, was used as a surrogate for treatment related mortality. Kaplan Meier survival curves were plotted and compared using log-rank test. Multivariate analysis was done using logistic regression and Cox proportional hazard regression model. All p values were two sided and the level of significance was chosen at 0.05. Results: A total of 6343 eligible patients were identified, which comprised 2836 (44.7%) AYAs. A total of 52% (n=3346) were males, whereas 76%(n=4825) were whites. Histologically, majority of patients (56%; n=3545) were categorized as AML, not otherwise specified, followed by acute monocytic leukemia (9.9%, n=630). Majority (55%; n-3509) of the patients were diagnosed between 2001-2012. The early mortality rate was lower in the pediatric AML patients (pAML) as compared to AYAs (6.2% vs 9.2%; p<0.01). Similarly the 1 year (70.3% versus 62.1%; p <0.01) and 5 year (48.2% vs 36.4%; p<0.01) was higher in pediatric patients as compared to AYAs. Kaplan Meier plot showed worse overall survival of AYAs compared to pAMLs (Figure 1; p value of log rank <0.01). Multivariate logistic regression showed higher early mortality among AYAs as compared to pAML patients (OR 1.48; 95% CI 1.23-1.79; p<0.01). Similarly Cox regression showed worse overall survival among AYAs as compared to pAML (HR 1.34; 95% CI 1.26-1.44; p <0.01) Conclusions: Our population based analysis shows worse overall survival among AYAs as compared to pAML patients. Future clinical trials specifically focused on this age group are warranted to establish appropriate treatment regimens in this population. Figure 1.

Abstract Background Multiple Myeloma (MM) is a clinically heterogeneous disorder of clonal plasma cells. Elevated Lactate Dehydrogenase (LDH) has been shown to be an independent prognostic marker associated with drug resistance and shorter survival. Methods Utilizing data from the Multiple Myeloma Research Foundation (MMRF) CoMMpass database (IA12) which includes over 1000 newly-diagnosed MM (NDMM) patients with enriched tumor and matched constitutional samples analyzed using whole genome/exome and RNA sequencing, we identified patients with baseline LDH values. High LDH was defined as LDH greater than the upper limit of normal, (>4.68 microkatals/liter). We compared baseline characteristics and outcomes with autologous stem cell transplant (ASCT), based on LDH as categorical variable. We sought to determine if there is enrichment of high and standard risk cytogenetic changes when stratified by LDH. Results We identified 871 patients with NDMM who had baseline LDH values. 143 patients had high LDH and 728 patients had a normal baseline LDH. Consistent with prior reports, high LDH was associated with shortened survival, 660 days vs 795 days (p=0.02852) in patients with normal LDH. 385 patients underwent ASCT (High LDH N=44; Normal LDH N=341). Those with high LDH had an inferior OS when compared with those with normal LDH (median OS 800.5 vs 878.8 days, p=0.019). In order to understand this difference, we examined baseline characteristics. Of the 44 patients with high LDH who underwent ASCT, median age was 60 years and ECOG performance status was 1. 61.36% were females, 77% were Caucasian, 11% were African American. Induction therapy consisted of 4 drugs or more in 16%, 3 drugs in 61%, and 2 drugs in 23%. Bortezomib and immune modulating agents (IMIDS) were combined in 72%. In those who did not receive an IMID, a bortezomib-based induction was used in 16% and carfilzomib-based induction was used in 11%. 93.18% underwent transplant in the consolidative setting with a median time to transplant was 178 days. 21 of the 44 patients (47.72%) received post-transplant maintenance. 10/21(48%) patients received triplet therapy (5/10 - lenalidomide, bortezomib, dexamethasone), 8/21 (38%) patients received lenalidomide alone. The median duration of maintenance was 217 days. Of the 341 patients with normal LDH who underwent ASCT, the median age was age 61 years, ECOG performance status was 1. 41.34% were females, 79% were Caucasian, 13% African American. Induction therapy consisted of 4 drugs in 8%, 3 drugs in 64%, 2 drugs in 24%. Combined Bortezomib-IMID in 76.24%, carfilzomib-IMID based therapy in 6%, and bortezomib-non-IMID based in 9.67%. 94.7% underwent an upfront consolidative with median time to transplant 164 days. Post-transplant maintenance was given in 213/341 (62.4%) of patients, in whom triplet therapy was given to 41/213 (19.2%), doublet therapy to 34/213 (16%), 130/213 (61%) received single agent. 107/213 (50%) received lenalidomide alone and 19/213 (6%) received bortezomib alone. Median duration of maintenance 266 days. There was no statistically significant difference in race, performance status, drug class and number of drugs used in induction therapy, time to transplant, whether or not patients received maintenance as well as maintenance duration between the groups when stratified by LDH. Female gender was enriched in the high LDH group (hypergeometric test, p=0.009). We used hypergeometric tests to assess for enrichment of high and standard risk cytogenetic changes. Del(17p13) was significantly enriched (p=0.011) in the high LDH subset where there were no statistically significant difference in the presence of t(4;14) (p=0.16) and t(14;16) (p=0.21). There was no difference in good risk hyperdiploid structural changes between the 2 groups. Conclusion Elevated LDH was confirmed as a poor prognostic factor in MMRF CoMMpass cohort. Among patients who underwent ASCT, those with high LDH have inferior survival, possibly driven by the presence of del(17p13). Since clinical outcomes remain poor despite the use of novel effective therapies and early consolidation with AHCT in patients with high baseline LDH, this group represents an unmet need for alternative therapy.

Abstract In the western countries, it has been well established that both immunoglobulin VH gene mutational status and CD38 expression are useful prognostic markers in chronic lymphocytic leukemia (CLL). However, it is not clear whether it is also true in other regions, especially such as Japan where CLL incidence is not so frequent as other countries. Therefore, we investigated the prognostic impact of VH gene mutational status and CD38 expression in Japanese B-CLL. The subjects of this study were 44 patients (29 males and 15 females) referred to our institutions between March 1999 and March 2004. The median age at the time of diagnosis was 68 years (37–92 years). The diagnosis was based on immunophenotypic analysis and cell morphology analyzed on Wright’s–stained peripheral blood and bone marrow smears. Median follow-up period of these patients was 4.0 years (0.5–34.2 years). cDNA mainly prepared from peripheral blood samples of the CLL patients was amplified using VH family-specific framework region primers or leader primers, and CH primers. PCR products were sequenced directly or after TA-cloning using the BigDye Terminator Cycle Sequencing FS Ready Reaction kit on a 310 Genetic Analyzer. Nucleotide sequences were compared to the nearest germ line VH genes in databases: IMGT, V-QUEST or IgBLAST. Of 44 B-CLL patients, IgH variable region genes could be sequenced from their cDNA in 43 patients; no amplified band was obtained in 1 patient. The usage of the seven VH gene families in the 43 B-CLL patients were as following: VH 1, 4/43 (9.3%); VH 2, 2/43 (4.6%); VH 3, 23/43 (53.5%); VH 4, 12/43 (27.9%); VH 5, 1/43 (2.3%); VH 6, 1/43 (2.3%); VH 7, 0/43 (0%). Eighteen cases (41.9%) displayed unmutated V H genes, defined as the sequences having more than or equal to 98% homology with nearest germ line gene, and 25 cases (58.1%) showed somatically mutated, defined as less than 98% homology. The proportion of unmutated cases in this study was almost comparable to previous reports, which showed a range of 30% to 50%. It have been uniformly reported that prognostic difference is apparent between unmutated (bad) and mutated (good) groups. Also in this study, the overall survival, defined as the time from diagnosis to death from any cause or to last contact, was significantly shorter for unmutated cases compared to mutated cases estimated by the Kaplan-Meier method as previous reports: predicted 50% survival rate for the unmutated cases was 9.1 years, but that for mutated cases did not reach the median survival. The difference was significant (p=0.029, log-rank test). Cell surface CD38 expression, which has been reported to correlate with a poor prognosis, was analyzed by flow cytometry in all patients. With the cut off level of 30% in CD19+CD5+ lymphocytes, 13 patients (29.5%) were estimated to be CD38 positive and 31 patients (70.5 %) to be negative. There was no significant difference in overall survival between those 2 groups (p=0.519, log-rank test). In conclusion, VH gene mutational status is a strong prognostic indicator whereas CD38 expression is not in our B-CLL cohort.
