Abstract Background: Autologous stem cell transplantation (ASCT) is now considered standard therapy in young patients (<65 years) with multiple myeloma (MM). The Intergroupe Francophone du Myelome conducted a randomized trial of the treatment of MM with high-dose chemotherapy followed by either one or two successive ASCTs. The probabilities of event-free-survival and overall survival were doubled with a double transplant. However, no randomized trial has compared tandem transplant up-front with a strategy including planned second ASCT at relapse or progression. Therefore, we performed a multicenter, sequential, randomized trial designed to assess the optimal timing of a second ASCT. Methods: From May 2003 to April 2006, 140 patients with symptomatic MM (de novo) and less than 60 years of age, were randomly assigned to receive either tandem transplantation up-front (within 6 months of the first transplantation) [Arm A, n=69] or one ASCT followed by a consolidation therapy with thalidomide (day +90, 100 mg/per day during 5 months) [Arm B, n=71]. Patients included in the arm B received a second transplant in case of disease progression on consolidation therapy, or in case of relapse in responders. Clinical characteristics of each group were similar. In both arms of the study, ASCT was preceded by first-line therapy with thalidomide-dexamethasone and subsequent collection of peripheral blood stem cells with high-dose cyclophosphamide (4 g/m2) and G-CSF. Data were analyzed on an intent-to-treat basis. Results: With a median follow-up of 23 months (range: 6–34), the 2-year overall survival was 55% in the arm A and 75% in the arm B. Survival curves were not different (P=0.28, log-rank test). The 2-year event-free survival was 41% in the arm A and 60% in the arm B (P=0.4, log-rank-test). In the arm B, relapse-free survival of ≥ 16 months following the first transplantation was an important predictor of overall survival (p< 0.001). Conclusion: Data from the present study suggest that up-front single ASCT followed by a consolidation therapy with thalidomide and a second ASCT after relapse or progression is a safe and effective global strategy to treat MM patients. Longer follow-up is needed before definite conclusions can be given concerning the optimal timing of second autologous transplantations in patients with MM.

672 Background: Investigation of high dose chemotherapy (HD-CT) supported by autologous hematopoietic stem cell transplantation compared with standard dose chemotherapy (SD-CT) as adjuvant treatment in patients with primary breast cancer and 10 or more axillary lymph nodes. Methods: Between November 1993 and September 2000 307 patients were randomized to receive the following cycles of Epirubicin (90 mg/m2), Cyclophosphamide (600 mg/m2) intervenously (every 21 days) either HD-CT of Cyclophosphamide (1500 mg/m2), Thiotepa (150 mg/m2) and Mitoxantrone (10 mg/m2) intervenously for 4 consecutive days followed by stem cell transplantation or standard dose chemotherapy SDCT in 3 cycles of Cyclophosphamide (500 mg/m2), Methotrexate (40 mg/m2) and Fluoruracil (600 mg/m2) intervenously on days 1 and 8 every 28 days. The primary end points were event-free survival and overall survival. Results: After a median follow-up of 6.1 years 166 events with respect to event-free survival (SD-CT: 91, HD-CT: 75) and 123 with respect to overall survival (SD-CT: 66 and HD-CT: 57) have been observed. The hazard ratio of HD-CT versus SD-CT is estimated as 0,80, p = 0,15. The hazard ratio for overall survival for high dose chemotherapy versus standard dose chemotherapy is estimated as 0,84, p = 0,33. Analysing the effect of treatment on event-free survival premenopausal patients, patients with tumor grade III and ER-positive patients had a better outcome with HD-CT with an interactive effect of 2.5 and 1.4. The significance was only shown in grade III patients in favour of HD-CT, (p = 0,049). The interactive effect of HD-CT with prognostic factors did not reach significance for overall survival. Conclusion: Even with a follow-up of 6.1 years there was only a trend in favour of high dose chemotherapy with respect to overall survival but without a statistical significance. A proper meta-analysis needs to be undertaken for an evaluation of subgroups of patients which might benefit from this treatment approach. No significant financial relationships to disclose.

Abstract Clinical trials on different cytarabine doses for treatment of AML provide evidence of a dose response effect, but also for increase toxicity after high dose AraC (HDAC). Pharmacokinetic measurements of cytarabine-triphosphate (AraC-CTP), which is the most relevant cytotoxic metabolite of AraC, have revealed its formation in leukemic cells to be saturated with infusion rates above 250 mg/m2/h, this being significantly lower than used in HDAC schedules. Methods: Based on a pharmacological model and encouraging results of a phase II study we conducted a prospective randomized multicenter clinical trial comparing the effects of two different application modes of AraC in patients up to 60 years with untreated newly diagnosed AML. Patients were randomized to receive AraC at two different infusion rates (IR) during induction and consolidation treatment: arm A/experimental: 1 × 2 g/m2/d AraC over 8 hours (IR 250 mg/m2/h) arm B/standard: 2 × 1 g/m2/d AraC over 3 hours (IR 333 mg/m2/h). Induction and first consolidation consisted of AraC (days 1, 3, 5, 7) in combination with an anthracycline (Idarubicine 12 mg/m2 or Mitoxantrone 10 mg/m2, days 1–3). The final dosage points (AraC day 7 and anthracycline day 3) were excluded from the second consolidation. The third consolidation consisted of either allogeneic or autologous stem cell transplantation or of chemotherapy identical to second consolidation. Results: From 02/97 to 04/02 419 patients were enrolled in the study. The present analysis is based on 361 eligible and evaluable patients with a median follow up of 7 years. CR was reached in 249/361 (69%; 95%CI: 65%–74%) patients. No statistically significant differences were detected between arms A and B with regard to CR-rate (69% vs 69%) or early death rate (11% vs 8%). Hematological recovery of median white blood cell count (WBC) &gt; 109/l and median platelets (plt) &gt; 50 × 109/l revealed no difference between arms A and B after induction (WBC day 22 vs 22, p=0,68; plt day 25 vs 26, p=0,41) and consolidation (WBC day 28 vs 27, p=0,07; plt day 42 vs 40, p= 0,58). The event free survival (EFS) after 5 years is 0,25 ± 0,03 % for all patients with an overall survival of 0,31 ± 0,03 % after 5 years. For the purposes of analysis, the 83 transplant patients (23 allogeneic MRD, 14 allogeneic MUD and 46 autologous) were censored at time of transplant. No statistically significant difference between arms A and B in regard to EFS (0,25 ± 0,04 vs 0,25 ± 0,04, p=0,99), relapse incidence (0,63 ± 0,06 vs 0,60 ± 0,06, p=0,89), overall survival (0,32 ± 0,04 vs 0,30 ± 0,04, p=0,44) and therapy associated mortality (0,18 ± 0,04 vs 0,17 ± 0,03, p=0,95) were detectable after adjustment of prognostic factors. An analysis of risk factors by multivariate cox regression model confirmed cytogenetics at diagnosis to be the most important risk factor for CR rate (p&lt;10−6) and for EFS (p&lt;10−6). Other significant prognostic factors for EFS evaluated in the multivariate analysis were de novo vs secondary AML (p=0,0001), WBC (continuous) (p=0,001), LDH (&gt;1–4 × vs other ULN) (p=0,008) and FAB classification (FAB M0,6,7 vs FAB M1,2,4,5) (p=0,0005). EFS after 5 years shows a significant correlation to cytogenetics (p&lt;10−6) with 0,71±0,1, 0,27±0,05, 0,20±0,06 and 0,03±0,03 for favorable, normal, other and unfavorable cytogenetic karyotype, respectively. Conclusion: We conclude that the application of AraC at the presumptive saturating infusion rate of 250 mg/m2/h results in comparable remission rates, toxicity, event free survival and overall survival as compared to the standard IR with 333 mg/m2/h.

The Impact

Abstract Background: Novel therapies are required to improve the outcome of patients with AML. New agents are asked to demonstrate an overall survival (OS) benefit before qualifying for FDA approval. The long duration of clinical trials required in order to achieve this endpoint hampers quick evaluation of candidate therapies, including novel agents. Identification of reliable surrogate endpoints for OS in AML is needed. Here we compare the results of therapy for patients with untreated AML ages 16-60 years on the Eastern Cooperative Oncology Group 1900 trial (E1900) of induction chemotherapy followed by consolidation and autologous transplant in order to evaluate the validity of an event free survival (EFS) endpoint as a surrogate for OS. Methods:OS was measured from randomization for induction therapy to death from any cause (censored at last contact). EFS was measured from randomization to induction treatment failure, relapse after compete response (CR), or death in remission (censored at last contact). Hazard ratios (HR) were computed using Cox proportional hazards models. The association between EFS and OS was evaluated using the Kendall tau-a rank correlation for censored data. Results:There were657 patients enrolled of which 426 patients relapsed or had induction treatment failure before death or date of last contact. Median EFS and OS were 8.0 months (95% CI, 6.3 to 9.7 months) and 23.6 months (95% CI, 16.9 to 23.6 months), respectively. With a median follow-up of 80.1 months, there is a statistically significant correlation between EFS and OS (Kendall tau-a = 0.467, 95% confidence interval (CI) = (0.425, 0.510), p<0.001). This correlation was similarly significant at a median follow-up of 25.2 months (Kendall tau-a = 0.361, 95% CI (0.323, 0.400), p <0.001) when the E1900 trial was originally reported (Fernandez et al. NEJM 2009). Key findings reported based on the original OS endpoint are similar when analyzed with an EFS endpoint (Table 1). High-dose daunorubicin (90 mg/m2) (DNR 90) confers both an EFS and OS benefit in patients aged < 50 years and patients with intermediate cytogenetic risk, and does not confer an EFS or OS benefit in older patients and patients with unfavorable cytogenetic risk, on univariate analysis. Divergent results are only seen in the small subset of favorable cytogenetic risk patients, where DNR 90 conferred an OS benefit (p=0.027) without an EFS benefit (p=0.32). Both EFS and OS endpoints consistently reflect the impact of mutation status on survival. The presence of a FLT3-ITD or DNMT3A mutation has a negative impact on both EFS and OS while an IDH2 mutation has a favorable impact on EFS and OS. The presence of a NPM1 mutation confers a favorable impact on EFS and OS in patients who received DNR 90 and did not impact EFS or OS in patients receiving standard-dose daunorubicin (45 mg/m2) (DNR 45). The presence of an IDH1 mutation does not impact EFS or OS. Conclusions:The results of E1900 demonstrating superiority of DNR 90 in AML induction in patients up to age 60 are concordant when using an EFS or OS endpoint. This is true for the group as a whole as well as for subgroups for which targeted agents are in development (FLT3/IDH2 inhibitors). Further investigation of whether EFS is a reliable surrogate for OS is warranted in AML. If confirmed, its use as a primary endpoint could be adopted by regulatory agencies in order to allow more rapid completion of clinical trials in AML and bring new therapies to AML patients in a timely fashion.

AbstractThe purpose of this study is to compare our standard chemotherapy regimen (CHVP [cyclophosphamide, doxorubicin, teniposide, and prednisone]) plus interferon with 4 courses of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) followed by high-dose therapy with autologous stem cell transplantation (ASCT) in treatment-naive patients with advanced follicular lymphoma. Four hundred one patients were included from July 1994 to March 2001: 209 received 12 cycles of CHVP plus interferon α for 18 months (CHVP-I arm) and 192 received 4 cycles of CHOP followed by high-dose therapy (HDT) with total body irradiation and ASCT (CHOP-HDT arm). Overall response rates were similar in both groups (79% and 78% after induction chemotherapy, respectively). One hundred thirty-one of the 150 patients eligible for HDT underwent transplantation (87%). Intent-to-treat analysis after a median follow-up of 7.5 years showed that there was no difference between the 2 arms for overall survival (P = .53) or event-free survival (P = .11). Patients with a complete response at the end of the induction therapy had a statistically longer event-free survival and overall survival (P = .02 and < .001, respectively). After long-term follow-up, our study showed that there was no statistically significant benefit in favor of first-line high-dose therapy in patients with follicular lymphoma. High-dose therapy should be reserved for relapsing patients.

ABSTRACT Initial results of the ROBOT, which randomized between robot-assisted minimally invasive esophagectomy (RAMIE) and open transthoracic esophagectomy (OTE), showed significantly better short-term postoperative outcomes in favor of RAMIE. However, it is not yet clarified if RAMIE is equivalent to OTE regarding long-term outcomes. The aim of this study was to report the long-term oncological results of the ROBOT trial in terms of survival and disease-free survival. This study is a follow-up study of the ROBOT trial, which was a randomized controlled trial comparing RAMIE to OTE in 112 patients with intrathoracic esophageal cancer. Both the trial protocol and short-term results were previously published. The primary outcome of the current study was 5-year overall survival. Secondary outcomes were disease-free survival and recurrence patterns. Analysis was by intention to treat. During the recruitment period, 109 patients were included in the survival analysis (RAMIE n = 54, OTE n = 55). Majority of patients had clinical stage III or IV (RAMIE 63%, OTE 55%) and received neoadjuvant chemoradiotherapy (80%). Median follow-up was 60 months (range 31–60). The combined 5-year overall survival rates for RAMIE and OTE were 41% (95% CI 27–55) and 40% (95% CI 26–53), respectively (log rank test P = 0.827). The 5-year disease-free survival rate was 42% (95% CI 28–55) in the RAMIE group and 43% (95% CI 29–57) in the OTE group (log rank test P = 0.749). Out of 104 patients, 57 (55%) developed recurrent disease detected at a median of 10 months (range 0–56) after surgery. No statistically difference in recurrence rate nor recurrence pattern was observed between both groups. Overall survival and disease-free survival of RAMIE are comparable to OTE. These results continue to support the use of robotic surgery for esophageal cancer.

Background Microalbuminuria is a marker of systemic endothelial dysfunction. We hypothesize that peritoneal albumin excretion in peritoneal dialysis (PD) patients, which is conceptually analogous to microalbuminuria in nonuremic patients, can predict cardiovascular disease in new PD patients. Method We studied peritoneal albumin excretion in 43 new PD patients. They were then followed prospectively for the development of cardiovascular events. All-cause mortality and duration of hospitalization for cardiovascular diseases were also recorded. Result The average duration of follow-up was 26.5 ± 17.6 months. During the follow-up period, 15 patients developed cardiovascular events. Event-free survival at 36 months was 81.4% and 53.6% for low (<300 mg/L) and high (≥300 mg/L) peritoneal albumin excretion groups respectively (log rank test, p = 0.042). By Cox regression analysis, the only independent factors for event-free survival were diabetic status and peritoneal albumin excretion rate. For every 100 mg/L increase in peritoneal albumin excretion, the adjusted hazard ratio of developing a cardiovascular event was 1.83 [95% confidence interval (CI) 1.11 – 3.02, p = 0.018]. Actuarial patient survival at 36 months was 85.7% and 59.1% for low and high peritoneal albumin excretion groups respectively (log rank test, p = 0.10). After adjusting for the duration of follow-up for individual patients, the average duration of hospitalization was 9.1 ± 16.2 and 21.7 ± 25.7 days per year of follow-up for low and high peritoneal albumin excretion groups respectively (Mann–Whitney U test, p = 0.012). Conclusion Although the sample size of our present study is small and does not have adequate statistical power, we conclude that peritoneal albumin excretion may be an important predictor of cardiovascular disease. Further studies are needed to examine the role of dialysate albumin excretion as a means of cardiovascular risk stratification in PD patients.

10036 Background: Standard treatment of osteosarcoma includes cisplatin and high-dose methotrexate (HD-MTX), but both agents are associated with significant toxicity and MTX administration requires complex pharmacokinetic monitoring. In our previous OS91 trial, the combination of carboplatin and ifosfamide with doxorubicin and HD-MTX yielded outcomes comparable to those of cisplatin-based regimens with less long-term toxicity in localized osteosarcoma. Methods: Between 1999 and 2006, we conducted a multi-institutional trial (OS99) to evaluate the activity of carboplatin, ifosfamide, and doxorubicin without HD-MTX in newly-diagnosed patients with localized osteosarcoma. Treatment comprised 12 cycles of chemotherapy given every 3 weeks: 3 consecutive cycles of carboplatin (dose targeted to AUC 8 mg/ml×min on day 1) and ifosfamide (2.65 g/m2 daily for 3 days) and one cycle of doxorubicin (25 mg/m2 daily for 3 days) followed by definitive surgery (week 12) and 2 additional cycles of carboplatin/ifosfamide and 3 cycles each of ifosfamide/doxorubicin and carboplatin/doxorubicin for a total of 35 weeks. The log rank test was used to compare survival and event-free survival (EFS) distributions. Results: A total of 72 eligible patients were enrolled. The median age was 13.4 years and 41 (57%) were male. The most common tumor site was the femur (n = 46; 64%). The median follow-up for survivors was 4.4 years. Forty of the 66 (60.6%) evaluable patients had good histologic response (tumor necrosis > 90%) to preoperative chemotherapy. There was no difference in EFS or survival distributions between OS99 and OS91. Four-year estimates of EFS were 68.1 ± 6.7% for OS99 compared to 70.2 ± 6.6% for OS91 (p = 0.89). The 4-year OS was 82.4% ± 5.7% for OS99 compared to 74.5% ± 6.3 for OS91 (p = 0.25). Conclusions: OS99 produced outcomes similar to cisplatin or HD-MTX containing regimens and offers an alternative treatment regimen especially for patients with renal compromise and institutions where pharmacokinetic monitoring of MTX is not available.

Intention To Treat

Abstract In this randomized multicenter study of 136 patients, 6 courses of CHOP (cyclo-phosphamide/doxorubicin/vincristine/prednisone) followed by rituximab (CHOP-R) were compared with rituximab-supplemented high-dose sequential chemotherapy with autografting (R-HDS) to assess the value of intensified chemo-therapy as a first-line treatment for high-risk follicular lymphoma (FL) after the introduction of monoclonal antibodies. The analysis was intention to treat with event-free survival (EFS) as the primary endpoint. Complete remission (CR) was 62% with CHOP-R and 85% with R-HDS (P < .001). At a median follow-up (MFU) of 51 months, the 4-year EFS was 28% and 61%, respectively (P < .001), with no difference in overall survival (OS). Molecular remission (MR) was achieved in 44% of CHOP-R and 80% of R-HDS patients (P < .001), and was the strongest independent outcome predictor. Patients relapsing after CHOP-R underwent salvage R-HDS in 71% of cases. Salvage R-HDS had an 85% CR rate and a 68% 3-year EFS (MFU, 30 months). We conclude that (1) achieving MR is critical for effective disease control, regardless of which treatment is used; (2) R-HDS ensures superior disease control and molecular outcome than CHOP-R, but no OS improvement; and (3) CHOP-R failures have a good outcome after salvage R-HDS, suggesting that relapsed/refractory FL could be the most appropriate setting for R-HDS–like treatments. This trial was registered at www.clinicaltrials.gov as no. NCT00435955.

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

PURPOSE: Because interferon gave promising results in the management of metastatic renal cell carcinoma in the 1980s, a multicentric randomized controlled trial was planned to compare adjuvant recombinant interferon alfa-2b (rIFNα2b) with observation after radical nephrectomy in patients with Robson stages II and III renal cell carcinoma. Overall and event-free survival were to be evaluated together with prognostic factors. PATIENTS AND METHODS: Overall and event-free survival curves for 247 patients (124 controls and 123 treated) were estimated by the Kaplan-Meier method and compared using the log-rank test. Cox’s multiple regression models were adopted to perform a joint analysis of treatment and prognostic factors. RESULTS: The 5-year overall and event-free survival probabilities were 0.665 and 0.671, respectively, for controls and 0.660 and 0.567, respectively, for the treated group; the differences were not statistically significant (2P = .861 for overall and 2P = .107 for event-free survival with the log-rank test). Regarding prognostic factors, only grade, pT, and pN demonstrated a significant prognostic role. First-order interactions of treatment with pT and pN category were investigated; a significant interaction was found between pN and treatment. A harmful effect of rIFNα2b in the 97 treated pN0 patients and a protective effect in the 13 treated pN2/pN3 patients were statistically significant. CONCLUSION: Adjuvant rIFNα2b is not indicated after radical nephrectomy for renal cell carcinoma. The protective effect in the small group of pN2/pN3 patients requires further investigation.
