7502 Background: Rituximab (R) prolongs the progression-free survival (PFS) in patients with follicular lymphoma (FL) when given either simultaneously with or as maintenance after chemotherapy only. Methods: In the current study the impact of R maintenance after remission induction with an R-containing combined immuno-chemotherapy (R-FCM) was evaluated. Patients with advanced stage relapsed or refractory FL and mantle cell lymphoma (MCL) were eligible. The study design comprized 4 courses of chemotherapy with Fludarabine (25 mg/m2/d days 1–3), Cyclophosphamide (200 mg/m2/d days 1–3) and Mitoxantrone (8 mg/m2/d day 1) (FCM) ± Rituximab (375 mg/m2/d day 0). Patients entering a complete (CR) or partial remission (PR) underwent a second randomization for R maintenance (4 weekly doses (375 mg/m2/d) at three and nine months after end of induction) or observation only. Randomization was stratified for histology, prior therapies (up to 2 lines vs. >2), induction (±R), and response (CR vs. PR). After improved outcome of the R-FCM arm had been observed in the initial 147 randomized patients, all subsequent patients received a combined immuno-chemotherapy induction. Results: 176 of 195 randomized cases are evaluable, 138 of whom had received an R-containing induction. In these patients (as well as the total group) the median PFS after end of induction has not been reached in the R-maintenance arm in contrast to 17 months in patients with no further treatment (p = 0.001). This improvement was seen both in FL (n = 81; p = 0,035) and MCL (n = 47; p = 0,049). More importantly, overall survival rate was also improved after R maintenance with borderline significance (3 y rate 82% vs. 55%; p = 0,056). No major sided effects of R maintenance have been observed and the rate of serious infections was similar in both study arms (p = 0.72). Conclusions: The final analysis of this study confirms that R maintenance after combined immuno-chemotherapy (R-FCM) is highly effective and improves the progression-free survival—with a strong trend towards improved overall survival—of patients with relapsed FL and MCL.

PURPOSE Before recognizing mantle-cell lymphoma (MCL) as a distinct entity, these patients were grouped into low-grade (LG) or intermediate-/high-grade categories (IGHG) according to the Working Formulation and received various therapies. This was a unique opportunity to evaluate characteristics, behavior, response to treatment, and outcome of patients with MCL from two phase III trials conducted by the European Organization for the Research and Treatment of Cancer (EORTC): EORTC 20855 IGHG and EORTC 20856 LG. PATIENTS AND METHODS After histologic review, 64 diagnosed MCL patients (29 IGHG and 35 LG) were compared with other patients in their respective trials. In the IGHG group, patients received cyclophosphamide, doxorubicin, teniposide (VM26), prednisone, vincristine, and bleomycin (CHVmP-VB) or modified doxorubicin, cyclophosphamide, etoposide (VP 16), mechlorethamine, vincristine, procarbazine, and prednisone (ProMACE-MOPP). In the LG group, after receiving cyclophosphamide, vincristine, and prednisone (CVP) induction, patients were randomized between maintenance treatment with interferon alfa-2a (IFN) or no further treatment. RESULTS MCL patients compared with IGHG subtypes showed a similar overall survival and response rate, but shorter duration of response and progression-free survival. Comparing with LG patients, their response rate, duration of response, and progression-free survival showed no difference, while their overall survival was nearly twice shorter. MCL patients treated with CHVmP-VB had the longest survival. No treatment showed any significant improvement in terms of progression-free survival. CONCLUSION These data confirm that MCL represents a clinicopathologic entity. In terms of survival, it behaves like IGHG subtypes, while in terms of progression-free survival, it behaves like LG lymphoma. It is still not clear which first-line treatment offers patients with MCL the best chance to obtain both a complete response (CR) and a long-term survival.

Background: We aimed to elicit treatment preferences in relapsed/refractory mantle cell lymphoma (r/r MCL). Materials & methods: A discrete-choice experiment comprising six attributes (‘overall survival’, ‘progression-free survival’, ‘fatigue’, ‘nausea’, ‘risk of serious infections’ and ‘treatment administration’) was administered to r/r MCL patients, physicians and the general population (GP) in Sweden and Germany. Results: 18 patients, 68 physicians and 191 GP members participated. ‘Overall survival’ was the most important attribute, followed by ‘risk of serious infection’ and ‘progression-free survival’ among physicians and the GP. In contrast, ‘treatment administration’ was the second most important attribute to patients, followed by ‘risk of serious infection.’ Conclusion: Preferences for characteristics differentiating treatments of r/r MCL varies between patients, physicians and members of the GP.

Mantle cell lymphoma (MCL) is an aggressive neoplasm characterized by the deregulated expression of cyclin D1 by t(11;14). The molecular mechanisms responsible for MCL's clinical behavior remain unclear. The authors have investigated the expression of p53, E2F-1, and the CDK inhibitors p27 and p21 in 110 MCLs, relating their expression to proliferative activity (Ki-67). For comparison, they have similarly analyzed low-grade (12 MALT, 16 CLL/SLL) and high-grade (19 DLCL) lymphomas. p53 was detected more frequently in large-cell MCL (l-MCL; 5 of 7) than in classical MCL (s-MCL; 13 of 103) and DLCL (8 of 19). In MCL and DLCL, the percentage of E2F-1+ nuclei was high, correlating with high Ki-67 expression. Most MCLs (91 of 112) and DLCLs (12 of 19) showed a loss of p27; MALT and CLL/SLL, however, were p27 positive. Reverse transcription–polymerase chain reaction and in vitro protein degradation assays demonstrated that MCLs have normal p27 mRNA expression but increased p27 protein degradation activity via the proteasome pathway. Correlation of MCL p53 and p27 expression with clinical data showed an association between reduced overall survival rates and the overexpression of p53 (P = .001), the loss of p27 (P = .002), or both. Loss of p27 identified patients with a worse clinical outcome among p53 negative cases (P = .002). These findings demonstrated that MCL has a distinct cell cycle protein expression similar to that of high-grade lymphoma. The loss of p27 and the overexpression of p53 in MCL are prognostic markers that identify patients at high risk. The demonstration that low levels of p27 in MCL result from enhanced proteasome-mediated degradation should encourage additional clinical trials. (Blood. 2000;95:619-626)

Abstract Rearrangements of the c-myc oncogene can be seen in 5–10% of patients with diffuse large B-cell lymphoma. However, studies examining the significance of this finding have yielded conflicting results. Therefore, we performed a retrospective analysis to determine the clinical significance of c-myc rearrangements in diffuse large B-cell lymphoma. The results of classical cytogenetic studies and FISH analyses were used to identify diffuse large B-cell lymphoma cases in the database of the Nebraska Lymphoma Study Group with or without c-myc rearrangements. Patients who were HIV positive and those with post-transplant lymphoproliferative disease were excluded. We identified 16 patients with diffuse large B-cell lymphoma and c-myc rearrangements. All patients were initially treated with doxorubicin- or mitoxantrone-containing chemotherapy regimens. The median age of these 16 patients was 61 years (range 40 to 80), and 5 (31%) were males. The International Prognostic Index (IPI) was 0–2 at diagnosis in 9 patients (56%), and 3–5 in 7 patients (44%). Eleven patients (69%) had bulky disease (≥ 5 cm) at diagnosis. No significant differences in outcome were identified when the 16 c-myc positive patients were compared with 97 c-myc negative diffuse large B-cell lymphoma patients in the same age range. The actuarial 5-year progression-free survival for the c-myc positive patients was 23% (95% CI 6% to 46%), as compared with 38% (95% CI 29% to 48%) for c-myc negative patients (p=0.17). The actuarial 5-year overall survival rates were 36% (95% CI 14% to 59%) and 47% (95% CI 36% to 56%), respectively (p=0.19). Classical cytogenetics and FISH analyses were also used to examine the 16 c-myc positive cases for bcl-2 rearrangements. Eight (50%) cases had rearrangements of bcl-2 in addition to c-myc rearrangements. These patients were similar to the c-myc positive/bcl-2 negative patients except for a higher likelihood of an elevated LDH level at diagnosis (88% vs. 25%; p=0.03). The actuarial 5-year progression-free survival for c-myc positive/bcl-2 positive patients was 0%, as compared to 33% (95% CI 6% to 66%) for patients with rearrangements of c-myc alone, and 37% (95% CI 28% to 47%) for c-myc negative patients. The actuarial 5-year overall survival rates were 12% (95% CI 1% to 42%), 47% (95% CI 12% to 76%), and 41% (95% CI 31% to 51%), respectively. A multivariate analysis, adjusting for IPI score, demonstrated that the relative risk (RR) of treatment failure was significantly worse for the c-myc positive/bcl-2 positive patients, as compared to the c-myc negative patients (RR 2.86, 95% CI 1.32–6.23; p=0.008). Similarly, mortality was also significantly worse for the c-myc positive/bcl-2 positive patients, as compared to the c-myc negative patients (RR 2.69, 95% CI 1.18–6.11; p=0.02). In contrast, no significant differences in treatment failure or overall survival were demonstrated when c-myc positive/bcl-2 negative patients were compared with c-myc negative patients. Our results demonstrate that the c-myc rearrangement is not associated with poorer survival in patients with diffuse large B-cell lymphoma. However, patients with rearrangements of bcl-2 in addition to c-myc had significantly worse progression-free survival and overall survival.

Abstract Preceding studies have shown that Rituximab prolongs the time to treatment failure (TTF) and response duration (RD) in follicular lymphoma (FL) when given either together with chemotherapy or as maintenance after a no R containing therapy. In the current study the impact of R maintenance on RD was evaluated after remission induction by an R-chemo combination. Patients with advanced stage relapsed or refractory FL and mantle cell lymphoma (MCL) were eligible. The study design comprized a first randomization between 4 courses of chemotherapy with Fludarabine (25mg/m2/d days 1–3), Cyclophosphamide (200mg/m2/d days 1–3) and Mitoxantrone (8mg/m2/d day 1) (FCM) versus FCM plus Rituximab (375mg/m2/d on day 0) (R-FCM). Patients entering a complete (CR) or partial remission (PR) underwent a second randomzation for observation only versus R maintenance with 4 weekly doses of R (375mg/m2/d) to be given at three and nine month after end of therapy. Both randomizations were stratified for histology and preceding therapy. The first randomization was stopped after 147 patients demonstrating a significant improvement for the R-FCM therapy in initial response, progression free survival and even overall survival (OS). So all subsequent patients received R-FCM. 174 cases are currently evaluable for the second randomization, 136 of whom had received R-FCM for remission induction. In these patients the median RD has not been reached in the R-maintenance arm whereas it is 17 months in patients with no further treatment after R-FCM (p=0.0024). This improvement was seen both in FL and MCL. This study demonstrates that R maintenance after R-FCM salvage therapy is highly effective and improves the outcome of patients with relapsed FL and MCL.

Abstract Background: Mantle cell lymphoma (MCL) is an unfavorable subtype of B-cell non-Hodgkin lymphoma characterized by median progression-free survival (PFS) and median overall survival (OS) of only 1.5 and 3–4 years respectively. Although high-dose therapy and an autotransplant may prolong OS, it does not result in a long-term disease free survival. Therefore, there is a need for novel therapeutic approaches for this entity. Methods: We conducted a single-arm phase II study in subjects with newly-diagnosed MCL to assess efficacy and safety of a novel intensive regimen R-MACLO-IVAM-T, a modification of a protocol designed by Magrath et al (JCO1996;14:925). The study size of 22 patients was based on precision of a two-sided 95% confidence interval for the 18-month progression free survival rate. Eligible subjects had a confirmed diagnosis of MCL using WHO criteria, age 18–75 years, ECOG PS ≤ 2, adequate organ function and no history of HIV or prior cancer. Lymphoma extent at presentation was assessed by standard staging procedures as well as esophagogastroduodenoscopy and colonoscopy. Prior to initiating thalidomide maintenance, subjects were enrolled in the STEPS® program. Cycle 1 consisted of R-MACLO: rituximab 375 mg/m2 IV on day 1, doxorubicin 45 mg/m2 IV on day 1, cyclophosphamide 800 mg/m2 IV on day 1 and 200 mg/m2/day on days 2–5, vincristine 1.5 mg/m2 on days 1 and 8 capped to 2mg, methotrexate 1.2 g/m2 IV on day 10 over 1 hour followed by 5.52 g/m2 IV over 23 hours followed by leucovorin 36 hours later. G-CSF was begun on day 13. When the ANC was >1.5×109/L, cycle 2 with R-IVAM was begun: rituximab 375 mg/m2 IV day 1, cytarabine 2 g/m2 IV every 12 hours on days 1 and 2, etoposide, 60 mg/m2 on days 1–5 and ifosfamide 1.5 g/m2 on days 1–5 with mesna. Fourteen days after ANC recovery from cycle 2, cycles 3 and 4 were given in identical fashion to 1 and 2. Four weeks after ANC recovery from cycle 4, subjects were re-staged and responses were assessed by standard criteria. Subjects achieving CR at the end of therapy received thalidomide 200 mg/day until MCL relapse or intolerable toxicity. Results: Accrual started in 4/2004 and ended in 3/2008 when the planned 22 subjects were enrolled. All subjects were evaluable for toxicity and 21 were evaluable for response. Median age was 56.5 years (range 39–73). All subjects had at least stage 3 disease with bone marrow involvement in 19 and gastrointestinal involvement in 10. Distribution according to IPI: 0–1 factor, 3; 2 factors, 8; 3 factors, 8; and 4 factors, 3. Twenty subjects had diffuse variant and 2 had blastic variant. Nineteen subjects completed all 4 cycles of therapy; treatment was stopped in 2 subjects after 2 and 3 cycles respectively, and one subject died during the first cycle. Of the 21 subjects completing 2 cycles of therapy, 20 achieved CR and one PR. Two subjects relapsed at 9 and 33 months respectively, while 19 remain relapse free after median follow-up of 25 months (range 5–51). With a total follow-up of 545 months, the estimated relapse rate is 4.4 per 100 patients per year. There were two deaths: 1 from sepsis on cycle 1 day 8 and the other in CR at 38 months from non-small cell lung cancer diagnosed 19 months after MCL. Common severe toxicities were grade 3–4 neutropenia, thrombocytopenia and anemia in 33%, 19% and 17% of R-MACLO cycles and in 50%, 88% and 68% of R-IVAM cycles respectively. There were 14 bacteremias in 82 cycles, 12 of which were after R-IVAM therapy. Six episodes of reversible grade 1–2 renal toxicity occurred after methotrexate. The thalidomide maintenance dose was reduced in 6 subjects due to grade 3–4 neutropenia and reduced or stopped in 8 subjects because of grade 3–4 peripheral neuropathy. Patients remain under follow-up for relapse and survival. Conclusions: R-MACLO-IVAM-T results in a high overall response rate of 100% (95% CR and 5% PR) and a low relapse rate. At a median follow-up of 25 months, median PFS and OS were not reached. The 2-year actuarial PFS of 94% compares favorably with previously reported 2-year actuarial PFS of 40% and 67% for CHOP-like regimens without and with upfront bone marrow transplantation (Blood2005;105: 2677). The contribution of thalidomide maintenance to this outcome requires additional study. A multicenter clinical trial is suggested.

Abstract Abstract 2676 Purpose Akt is a serine/threonine kinase that plays a central role in cell proliferation and growth. To define clinical impact of Akt expression in diffuse large B-cell lymphoma(DLBCL), we investigated the expression of phospho-Akt(p-Akt) in DLBCL and analyzed clinical impact of p-Akt expression on patient survival. Methods We evaluated the p-Akt expression in 99 DLBCL patients using tissue microarray(TMA) technology. Results Positive p-Akt expression was observed in 15.2% of the patients and significantly associated with elevated lactic dehydrogenase level (P = .044). Kaplan-Meier survival analysis showed that the patients with positive p-Akt expression showed substantially poorer overall survival (p-Akt+ vs p-Akt- 25.3 months [95% confidence interval(CI), 14.4–36.2 months] vs 192.6 months [95% CI, 131.3–253.9 months], P < .001) and progression-free survival (p-Akt+ vs p-Akt- 13.6 months[95% CI, 14.4–36.2 months] vs 134.5 months [95% CI, 131.3–253.9 months], P < .001), respectively. Multivariate Cox regression analysis revealed that patients with DLBCL with p-Akt positivity showed poorer overall survival with 3.2 fold (95% CI, 1.6–6.8, P = .002) risk for death compared to patients with DLBCL with p-Akt negativity. Conclusion Positive expression of p-Akt in DLBCL patients is associated with poorer overall and progression-free survival. Expression of p-Akt may act as an independent poor prognostic factor and might be a novel therapeutic target for DLBCL. Disclosures: No relevant conflicts of interest to declare.

Mantle cell lymphoma is a well-recognized distinct clinicopathologic subtype of B-cell non-Hodgkin lymphoma. The current World Health Organization (WHO) classification subdivides this entity into aggressive and other variants. The disease has a predilection for older males, and patients typically present at an advanced stage with frequent splenomegaly and extranodal involvement including bone marrow, peripheral blood, gastrointestinal, and occasional central nervous system involvement. Early studies of therapy outcomes in this disease revealed that while response rates where high, relapse was expected after a limited period of time. Prolonged survival was uncommon, with initial median survival rates typically in the 3–4-year range. Those with a high proliferative rate, blastoid morphology, and selected clinical features were recognized as having a worse prognosis. Therapeutic approaches have diverged into aggressive therapies with high response rates and promising progression free survival rates, which may be applied to younger healthy patients, and less aggressive approaches. Aggressive therapies include intensive chemotherapy alone or chemotherapy followed by autologous stem cell transplant, which has been shown to be most effective when applied in first remission. Whether these more intense therapies result in improved survival as compared with less aggressive therapies is not well established. Allogeneic transplant has also been investigated, although high treatment-related mortality and the risk of chronic graft versus host disease and the relatively advanced age of this patient population have tempered enthusiasm for this approach. A number of less aggressive therapies have been shown to produce promising results. Consolidation and maintenance strategies are an active area of investigation. A number of newer agents have shown promising activity in relapsed disease, and are being investigated in the front-line setting. Overall survival rates are improving in this disease, with current studies suggesting a median survival of 5 or more years.
