Abstract Background: ESA have been reported to effectively improve the hemoglobin (Hb) in pts with CML who develop anemia during the course of therapy with imatinib and other tyrosine kinase inhibitors. Recently, it has been suggested that when ESA were administered to target a Hb ≥12 g/dL, they may promote tumor growth and decreased survival among pts with advanced head and neck cancer receiving radiation therapy, pts with non-small cell lung cancer, and pts with metastatic breast cancer receiving chemotherapy. We thus investigated whether pts with CML who had received ESA during the course of therapy with imatinib had an inferior long-term outcome. Methods: We analyzed the outcome of 565 pts with CML in chronic phase treated with imatinib in our institution (306 previously untreated, 259 post imatinib failure). Results: Based on the Common Terminology Criteria for Adverse Events (CTCAE) V. 3.0 of the National Cancer Institute (NCI), grade 1 anemia occurred in 235 (42%) pts, grade 2 in 180 (32%), grade 3 in 47 (8%), and grade 4 in 12 (2%) pts. A total of 245 (43%) pts received ESA at some point during the course of therapy. The median nadir Hb among pts treated with ESA was 9.4 g/dL [45 (18%) with grade 3–4 anemia] vs 11.2 g/dL [14 (4%) with grade 3–4 anemia] in those not treated with ESA. Treated patients received therapy with variable intermittent doses during a median time of 14 months (mo) range (1–96 mo). The observed increase in Hb with ESA therapy was >3 g/dL in 132 (54%) pts, 2–3 g/dL in 64 (26%), 1-<2 g/dL in 35 (14%), and <1 g/dL in 14 (6%) pts. The median Hb level achieved with ESA was 12.6 g/dL. The table summarizes the 5-year overall survival and event free survival (EFS) among pts treated with ESA and those not treated with ESA: As previously reported (Cortes et al. Cancer2004; 100:2396–402), the presence of anemia itself has a significant adverse effect on outcome in this patient population. The 5-year EFS for pts with anemia grade 3–4 was 56% vs. 79% for those with grade 0–2 (p=0.002). Corresponding figures for 5-yr OS were 82% and 88% (p=0.006). Conclusion: There is no evidence that the use of ESA to manage anemia associated with imatinib therapy in pts with CML in chronic phase adversely affects long term overall survival or event-free survival.

Abstract Abstract 1795 Introduction. The combination of fludarabine and cyclophosphamide (FC) has become the core combination of modern frontline chemotherapy for fit and young B-CLL patients (pts). Recently the association with rituximab to FC (IV administration) has been shown to increase the response and extend both progression free survival (PFS) and overall survival (OS) in untreated pts (Hallek et al., Lancet 2010). So far few data are available concerning the very long term outcome of pts treated by FC containing regimen. Methods. We previously reported a prospective phase II trial (Cazin et al., BJH 2008) of the oral combination of FC over 5 days in 75 patients with untreated B-CLL and less than 66 years old. The study was conducted between October 1999 and February 2001. Briefly, oral FC then demonstrated high efficacy with overall response rate (ORR) and complete response (CR) rate of 80% and 53% respectively despite the absence of rituximab in this regimen. We here propose to examine 10-year end points of progression-free survival (PFS), overall survival (OS), impact of genomic features, and risk of therapy-related myeloid neoplasm (t-MN) by updating survival data of all the pts incuded in this trial. Results. With a median follow-up of 10.7 years, the median 10-year OS was 51.7%. Responders presented better 10-year OS than non-responders (57% vs. 38%, p=0.031) but quality of response (CR vs. PR) did not significantly impact 10-year OS. A major prognostic impact of IGVH mutational status could be observed since 10-year OS was 81% for mutated patients vs. 44% for unmutated pts (p=0.012). The median 10-year PFS was 30% and clearly influenced by the mutational status (50% if mutated profile vs. 12% if unmutated profile, p=0.02). However there is no trend of a plateau and even long term responding patients still relapse with time. Finally, only one patient developed t-MN but 9 others presented solid neoplasms. Conclusion. Long-term follow-up of B-CLL patients prospectively treated in a phase II clinical trial demonstrates extended OS and PFS with oral FC without high risk of t-MN.

Abstract The introduction of imatinib has significantly changed prognosis of CML patients. Despite favourable hematologic and cytogenetic response (CyR) data, patients (pts) on first line imatinib therapy may relapse. Thus, studies have been conducted to improve initial therapy by dose escalation or combination with other drugs. CML Study IV was designed to compare imatinib in standard dose (400 mg/d) vs high dose (800 mg/d) vs combinations with low dose cytarabine or interferon alpha. We sought to evaluate the predictive impact of early molecular response for long term event free survival (EFS). 539 pts (59% m, median age 54 years, range 16–84) randomized to imatinib based therapies by December 2005 were investigated, the median follow up was 39 mo (range, 0–69). At baseline, multiplex PCR was applied to determine the dominating BCR-ABL transcript: b2a2 (n=204), b3a2 (n=247), b2a2 and b3a2 (n=80), e1a2 (n=2), e19a2 (n=4), b3a3 (n=1) and e8a2 (n=1). Quantitative PCR from 5,419 peripheral blood samples was performed using the LightCycler technology in two central labs. PCR data were aligned to the international scale (IS) by introduction of conversion factors (Hughes et al., BLOOD 2006). Cumulative molecular response of 539 pts at 3, 6, 12, 18, and 24 mo after randomization is summarized in the Table: Month 3 6 12 18 24 BCR-ABLIS Achieved by % of pts ≤10% 41 66 81 85 86 ≤1% 16 41 65 76 78 ≤ 0.1% (MMR) 3 16 37 51 59 ≤0.01% 1 3 10 21 28 For analysis of prognostic impact, events were defined as (i) loss of complete hematologic response, (ii) loss of major CyR following loss of complete CyR, (iii) accelerated phase, (iv) blast crisis, and (v) death for any reason. Pts were censored at the time of allogeneic stem cell transplantation or switch to 2nd generation tyrosine kinase inhibitors because of imatinib intolerance or resistance. The minimum molecular response levels predictive for EFS were BCR-ABLIS of 10% after 6 mo (p=0.0029), 1% after 12 mo (p<0.0001), and 0.1% (major molecular response, MMR; p=0.0016) after 18 mo of imatinib based therapies. In order to investigate the reasons for unsatisfying responses BCR-ABL kinase domain mutations were assessed in 175 pts. 30 pts (17%) harbored 35 mutations affecting 18 different aminoacids. In conclusion, prospective molecular surveillance of CML shows that early response predicts stable remissions on first line imatinib therapy. After 6 mo of treatment, PCR data start to be predictive for EFS. In pts with unsatisfactory response or molecular, cytogenetic and hematologic relapse, BCR-ABL mutations have been detected in only 17% of pts. Calculation of molecular response rates dependent on the various imatinib based therapies will be performed after stop of randomization which is expected by the end of 2009.

Background:Aortitis is a group of disorders characterized by the inflammation of the aorta. The most common causes of aortitis are the large-vessel vasculitis i.e. giant cell arteritis (GCA) and Takayasu arteritis (TA). However, aortitis may be isolated. Because of the wide variation in the course of aortitis, predicting outcome is challenging. The optimal management strategy of isolated aortitis (IA) is still unclear as IA is poorly defined, with data consisting of small retrospective and case control studies.Objectives:To assess the long-term outcome and prognosis factors for vascular complications in patients with isolated aortitis.Methods:Retrospective multicenter study of 353 patients with non-infectious aortitis including 136 giant cell arteritis (GCA), 96 Takayasu arteritis (TA) and 73 isolated aortitis (IA). Factors associated with event-free survival, vascular event-free survival and revascularization-free survival were assessed. Risk factors for vascular complications were identified in multivariate analysis.Results:After a median follow up of 52 months, vascular complications were observed in 32.3 %, revascularization in 30 % and death in 7.6%. The 5-year cumulative incidence of vascular complications was 58% (41; 71), 20% (13; 29), and 19 % (11; 28) in IA, GCA and TA, respectively. In multivariate analysis, IA [HR, 1.85 (1.19 to 2.88), p=0.017] and male gender [1.77 (1.26 to 2.49), p<0.0001] were independently associated with vascular events. The 5-year surgery-free survival was 45% (31; 65), 71% (62; 81) and 76% (68; 86) in IA, TA and GCA, respectively.Conclusion:IA has a worse vascular prognosis than GCA and TA. Sixty percent of IA patients will experience a vascular complication within 5 years from diagnosis.Disclosure of Interests:None declared

Purpose To compare the effectiveness and tolerability of epirubicin and paclitaxel (EP) with epirubicin and cyclophosphamide (EC) as first-line chemotherapy for metastatic breast cancer (MBC). Patients and Methods Patients previously untreated with chemotherapy (except for adjuvant therapy) were randomly assigned to receive either EP (epirubicin 75 mg/m2 and paclitaxel 200 mg/m2) or EC (epirubicin 75 mg/m2 and cyclophosphamide 600 mg/m2) administered intravenously every 3 weeks for a maximum of six cycles. The primary outcome was progression-free survival; secondary outcome measures were overall survival, response rates, and toxicity. Results Between 1996 and 1999, 705 patients (353 EP patients and 352 EC patients) underwent random assignment. Patient characteristics were well matched between the two groups, and 71% of patients received six cycles of treatment. Objective response rates were 65% for the EP group and 55% for the EC group (P = .015). At the time of analysis, 641 patients (91%) had died. Median progression-free survival time was 7.0 months for the EP group and 7.1 months for the EC group (hazard ratio = 1.07; 95% CI, 0.92 to 1.24; P = .41), and median overall survival time was 13 months for the EP group and 14 months for the EC group (hazard ratio = 1.02; 95% CI, 0.87 to 1.19; P = .8). EP patients, compared with EC patients, had more grade 3 and 4 mucositis (6% v 2%, respectively; P = .0006) and grade 3 and 4 neurotoxicity (5% v 1%, respectively; P < .0001). Conclusion In terms of progression-free survival and overall survival, there was no evidence of a difference between EP and EC. The data demonstrate no additional advantage to using EP instead of EC as first-line chemotherapy for MBC in taxane-naïve patients.

Abstract Background: Melphalan-based high-dose therapy (HDT) with autologous peripheral blood stem cell support has become the standard of care for newly diagnosed patients with MM, based on IMF90 and MRC7 trial results of single HDT vs. standard-dose therapy and on IMF94 data demonstrating superior EFS and OS with TAT over single HDT. The aim of this report is to provide a detailed account of the long-term outcome of all 231 patients originally enrolled in TT1 between 8/1990 and 6/1995 of whom 63 remain alive. Patients and Methods: Outcome data on TT1 have been reported previously (Blood93, 1999; 101, 2003). Here we give final account of patient status with a median follow-up of 12 years (range, 9–15). Results: Of 231 patients, 195 had received at least 1 and 165 the 2 scheduled transplants; 7 without insurance coverage were given intermediate dose melphalan 70mg/sqm. Of 87 (38%) initially achieving CR (median, 27 mo), 17 (20%) remain in uninterrupted 1st CR. The median EFS duration was 31mo, and 32 (14%) remain continuously event-free. The median OS duration is 68 mo with a 12-yr estimate of almost 30%. Of all 63 survivors, 19% had cytogenetic abnormalities (CA) prior to therapy, and 38% had CA intermittently. Of the 17 patients in continuous CR, 10 never had CA at any time, 4 developed CA subsequently with resolution in 3; of 3 with baseline CA, 2 normalized and 1 persisted. A detailed account of CA type and frequency as well as salvage therapies such as thalidomide, bortezomib and further auto- or allotransplants will be provided. Conclusion: TT1 was the first tandem autotransplant protocol applied to 231 newly diagnosed patients MM that yielded an unprecedented positive outcome with 12-yr rates of CCR, EFS and OS of 20%, 14%, and 30%, respectively. The Figure displays a 3-phasic relapse pattern: an initial steep slope spanning years 1-3, a more shallow slope between years 4 to 10, merging into a cure-consistent “hockey-stick”.

Abstract Abstract 3438 Background: The standard of care for most patients (pts) with CML has been imatinib mesylate at a dose of 400mg by mouth daily. Earlier studies have suggested that there may be a benefit to pts to start treatment at a higher dose as this may result in faster and more durable responses to imatinib. It is not yet known whether long-term event-free survival (EFS), transformation-free survival (TFS), and overall survival (OS) will be impacted by the higher dosing schedule. Objectives: To determine the long term responses and clinical benefit of imatinib 800mg daily versus 400mg daily dosing when used as upfront treatment strategy in CML. Methods: We conducted sequential prospective trials using imatinib 400mg or 800mg daily as initial therapy for patients with previously untreated chronic phase CML. Results: A total of 281 pts were included in these trials: 208 treated with 800mg and 73 with 400mg. The median follow-up for each group was 79 months (range: 3–107) and 110 months (range: 2–116). The overall, cumulative rate of complete cytogenetic response (CCyR) was 91% and 87%, respectively (p=0.49) for those treated with high- and standard-dose, and the cumulative rate of major molecular response (MMR) was 87% and 78%, respectively (p=0.06). Rates of CCyR at 12 months were 90% and 66%, respectively (p < 0.001), and MMR at 18 months 82% and 68%, respectively (p=0.04). A significantly better EFS (definition per IRIS criteria) was observed for the 800 mg group compared to that in the 400mg group (log-rank test, p=0.049; estimated 7-year EFS 86% vs 76% by Kaplan-Meier method). No significant differences were seen for survival free from transformation to accelerated and blast phase (p = 0.46) and overall survival (p = 0.27). For OS, thus far 19 pts in the 800mg group have died (2 probable CML-related, 3 unknown causes, 14 non CML related) compared to 13 pts (10 probable CML-related, 3 non CML-related) in the 400mg group. The table below shows the annual rate of events and transformation for each dose group. Treatment discontinuation for toxicity occurred in 16 (8%) pts treated with 800mg and 6 (8%) pts treated with 400mg. Conclusions: At 7-year follow up, pts treated with 800mg demonstrated a significantly better EFS (by IRIS criteria) compared to those treated with 400mg. There is a trend for a lower annual rate of events and transformation with the higher dose, particualry in the earlier years, but no difference in OS. These results suggest a modest benefit for patients treated with higher dose imatinib. Disclosures: Off Label Use: imatinib at dose of 800mg po daily for CML.

Abstract Background: Presence of myelofibrosis on bone marrow examination is considered as poor prognostic factor in patients with chronic myelogenous leukemia (CML). Scant data is available on myelofibrosis, especially in the era of tyrosine kinase therapy. The present study was designed to analyze impact of myelofibrosis on outcomes in newly diagnosed patients with chronic myeloid leukemia in chronic phase (CML-CP). Aims and objectives: The primary objective of this analysis was to study event free survival (EFS) and major molecular response rates (MMR) at one year in patients with CML-CP with myelofibrosis. Secondary objectives were to study the parameters impacting outcomes in patients with CML-CP with myelofibrosis Materials and methods: Study period: 2010 to 2016 Type of study: retrospective analysis. The diagnosis of CML-CP was done by demonstration of BCR-ABL translocation by polymerase chain reaction or fluorescence in situ hybridization. Event free survival was defined as the time from start of therapy to death, transformation to accelerated or blast phase, hematologic resistance or toxicity intolerance. Statistical analysis was done using SPSS software, version 25. Overall survival curves were plotted using the Kaplan-Meier method. Grade of myelofibrosis, EUTOS risk, age and compliance were analyzed on multivariate analyses. Results: Data of 147 patients with CML-CP with myelofibrosis at presentation was retrospectively collected, of which 79(53.7%) were males and 68(46.3%) were females. The baseline characters were tabulated in Table 1. Abdominal fullness (60.5%) was the most common symptom at presentation followed by fatigue (48.9%), weight loss (36.7%), fever (25.1%) and bleeding manifestations (12.9%). EUTOS risk was low in 94(64%) patients and high in 53 (36%) patients. Myelofibrosis grade 1, 2, 3 and 4 were seen in 20(13.6%), 36(24.5%), 38(25.9%) and 27(18.3%) patients respectively. Grade of myelofibrosis was not available in 26(17.7%) patients. Of 147 patients, outcome parameters were available in 92 patients. Of 92 patients, 34(37%) attained MMR at 1 year. At a median follow up of 46 months, event free survival was 60.9%. Of 92 patients, MMR at one year differed significantly in patients with grade 1 and 2 myelofibrosis (48.8%) compared to patients with grade 3 and 4 myelofibrosis (26.5%) (p=0.02). Event free survival was higher in patients with grade 1 and 2 myelofibrosis (76.7%) compared to patients with grade 3 and 4 myelofibrosis (46.9%) (p=0.005). Drug induced myelosuppression was seen in 27(29.3%) patients, of which 7(26%) patients received dose reduction. Phase transformation was seen in 6 patients, of which 1(16.7%) and 5(83.3%) patients were transformed to accelerated phase and blastic phase respectively. On multivariate analysis, only grade of myelofibrosis had significant impact on event free survival(p=0.013). Conclusion: In patients with newly diagnosed CML-CP, major molecular response was significantly lower for those with higher grade of myelofibrosis. Grade of myelofibrosis at presentation had significant impact on outcomes in CML-CP. Hence, bone marrow examination for presence and grade of myelofibrosis helps in prognosticating CML-CP patients.

This study evaluated the correlation between tumor-associated macrophages (TAMs) and long-term oncologic outcomes in colorectal cancer (CRC). We evaluated TAMs based on the expression of CD68, CD11c, and CD163 as optimal markers via immunohistochemistry in 148 patients with CRC who underwent surgical resection between September 1999 and August 2004. A high proportion of CD68-positive macrophages were associated with the occurrence of distant metastasis. A low proportion of CD11c-positive macrophages were associated with unfavorable overall survival (OS) and disease-free survival. CD11c-positive macrophages were found to act as independent prognostic factors for OS. An analysis of our long-term data indicated that TAMs are significantly associated with OS and prognosis in CRC.
