Abstract Background FISH abnormalities including t(14;16), t(14;20), t(4;14) and the loss of P53 remain a common mechanism for classifying patients (pts) with newly diagnosed multiple myeloma (MM) as adverse risk. In contrast, trisomies in MM are associated with superior outcomes and may ameliorate the negative prognostic significance conferred by adverse FISH abnormalities. High dose therapy (HDT) consisting of high dose melphalan and autologous stem cell transplantation with consideration of maintenance therapy is a common treatment strategy for transplant eligible MM pts. However, there is limited information regarding the impact of various cytogenetic abnormalities, alone or in combination with trisomies, in the context of HDT, and the efficacy of maintenance approaches in the novel agent era. Aim To determine the clinical significance of FISH abnormalities in MM pts undergoing HDT and subsequent consideration of maintenance therapy in recent years. Methods We retrospectively examined a cohort of all pts with MM who underwent first HDT at Mayo Clinic Rochester between 2008 and 2012. Medical records were reviewed under IRB approval in accordance with the principals of the Helsinki declaration. FISH results were obtained from within 6 months of diagnosis (Dx), and if unavailable pts were excluded. Pts were considered for maintenance therapy following response assessment by their treating hematologist, typically around day 100 following HDT, and were categorized based on the intent of that discussion; length of maintenance and dose reductions were not evaluated. PFS and OS were calculated from date of transplant and OS was also estimated from Dx. Timing of HDT was restricted to within one year of MM Dx (early HDT). Results 300 pts had available FISH and underwent early HDT. Median age at dx was 60 (23-75), and median follow up from Dx was 40 months (7.5-90) with 229 (76%) alive at time of analysis. The median time to HDT from Dx was 5.8 months (95% CI 5.4-8.0). At the time of HDT 249 pts (83%) were in a partial response or better. Overall, 73 pts (24%) had adverse risk FISH from dx as described, 154 pts (51%) had at least one trisomy, and 32 pts (10.7%) had a concomitant adverse FISH abnormality and a trisomy. Of all pts, 112 (37%) received maintenance therapy of some sort, most commonly single agent lenalidomide (n=67 pts) or bortezomib (n=36). Of the 73 pts with adverse FISH, 54 (74%) received maintenance therapy following initial HDT compared with 58 of 227 pts (26%) with non-adverse FISH. Among pts with adverse FISH, median PFS and OS was 21 months (95% CI 16-24) and 57 months (95% CI 41-NR) respectively, compared with 24 months (95% CI 21-26) and not met respectively for pts with no adverse FISH (p =0.08 and p=0.04). The OS from Dx was 63 months (95% CI 46-NR) and not met, respectively for pts with adverse FISH and no adverse FISH (p=0.04). Among adverse FISH pts, PFS following initial HDT was improved with any maintenance therapy (23 months (95% CI 18-33) versus 13 months (95% CI 6-22), p=0.0016). OS was not statistically different among pts with adverse FISH whether or not they received maintenance therapy, both from date of HDT as well as from Dx. For pts with non-adverse FISH at Dx similar findings were observed, with an increase in PFS following HDT with any maintenance therapy (30 months (95% CI 23-48) versus 22 months (18-24)), without a difference in OS. Further analysis of the group of pts with adverse FISH status revealed the PFS benefit seen with maintenance therapy was greatest for a subgroup of pts with concomitant trisomies (29 months (95%CI 18-38) versus 14 months (95%CI 8-16) p=0.0003) as compared to pts with adverse FISH without concomitant trisomies (19 months (95%CI 13-35) versus 12 months (95% CI 3-24) p=0.204) (figure 1). However, OS either from HDT or Dx did not differ for pts with adverse FISH with or without concomitant trisomies regardless of maintenance status. Conclusions Our data support an improvement in PFS with maintenance therapy following initial HDT amongst adverse risk FISH MM pts, however no OS benefit was observed with maintenance therapy irrespective of FISH status. Among pts with adverse FISH, maintenance strategies improve PFS for pts with a concomitant trisomy. No PFS benefit was seen with maintenance therapy in pts without concomitant trisomies. Future trials of maintenance therapy post HDT should consider evaluating and reporting on the subgroup of adverse FISH pts with concomitant trisomies. Figure 1 Figure 1.

Dose Therapy

Overview: Maintenance therapy in multiple myeloma has been under investigation for more than 3 decades and has been without evidence of clear advantage in terms of progression-free survival (PFS) until the mid-2000s. Neither conventional chemotherapy, prednisone, nor interferon-based maintenance regimens offered any benefit after conventional or high-dose therapy. Thalidomide was the first drug, mainly given as maintenance after high dose therapy, to demonstrate clinical benefits in terms of PFS and, in some studies, of overall survival (OS). The role of other novel agents such as lenalidomide and bortezomib as maintenance therapy is emerging. Lenalidomide has been shown to reduce the risk of relapse with longer follow-up needed to see if this will translate into a survival benefit. At present, a number of key questions remain unanswered. What are the optimal dose and duration of those treatments? Is the risk of toxicity and second primary malignancies acceptable? Will the disease be more aggressive at time of relapse? Is the clinical benefit predicted by initial prognostic factors and response to previous therapy? Does maintenance therapy work by further eradication of minimal residual disease or by immunological control of the malignant clone? Ongoing randomized trials are evaluating lenalidomide and bortezomib, both in the transplant and nontransplant settings, to better define the role of these drugs as maintenance in multiple myeloma.

Abstract Background: Thalidomide/Dexamethasone (TD) has become one of the most commonly used induction therapies for patients with symptomatic multiple myeloma (MM) eligible for high dose therapy (HDT) intensification with autologous stem cell transplant (ASCT). Bortezomib (Velcade) has been added to the combination of TD (VTD) in an effort to reduce MM tumor burden further prior to HDT.The impact of this addition on HDT outcomes has not been fully explored. Purpose: To determine the impact of the addition of bortezomib to TD induction therapy in patients with MM undergoing HDT and ASCT consolidation. Patients and Methods: Patients were eligible for this analysis if they had undergone HDT with ASCT for first remission consolidation or primary refractory disease within 12 months of diagnosis between 9/03 and 12/05 and had received either TD or VTD as induction therapy. Patients receiving VTD after TD were excluded. Patients receiving more than 1 chemo regimen other than TD or VTD were excluded. Chemomobilization was NOT considered an exclusion criteria. Results A total of 78 patients qualified for the analysis (27 VTD; 51 TD). Patient and treatment characteristics are summarized in table 1. In brief, the patients receiving VTD had a higher rate of cytogenetic abnormalities and received less cycles of chemotherapy prior to SCT. Although pre-SCT response rates were similar between patients receiving VTD or TD (95% vs 92%) there was a trend for a higher CR rate in the VTD group (15% vs 6%). Post transplants response rates assessed between 3–6 months demonstrated that 28% and 38% of VTD patients achieved near CR and CR respectively while 19% and 23% had these responses post TD induction. There was no difference in 2 year OS and PFS among patients receiving VTD or TD (91% vs 81% and 35% and 56% respectively). Conclusion: Both VTD and TD as induction treatment are associated with high response rates prior to SCT as well as 6 months post SCT. In this retrospective analysis no survival benefit was seen for induction therapy with VTD over TD, despite higher near CR and CR rates. However randomized trials need to be performed addressing type of induction as well as duration of induction therapy prior to high dose therapy consolidation.

Abstract Previous studies have shown that specific chromosomal abnormalities are of major prognostic significance in patients with multiple myeloma (MM). It has been recently suggested that a t(11;14)(q13;q32) may be an indicator of favorable outcome in MM. In this investigation, we analyzed 163 patients with newly diagnosed MM (53% treated by high-dose therapy) to address the question whether or not the simultaneous occurrence of a t(11;14) and a deletion 13q [del(13q)], an established negative prognostic factor in MM, has any impact on prognosis. DNA-specific probes for IgH (14q32) and cyclin-D1 (11q13) were used for interphase FISH analysis of clonal plasma cells (cytoplasmic Ig positive). A t(11;14) by FISH was shown in 27 of the 163 MM patients (16.6%); the abnormality was present in the majority (median, 89%) of clonal plasma cells. Immunohistochemical analysis of CYCLIN-D1 expression was carried out in 72 patients, of whom 11 had a t(11;14) by FISH; all 11 patients had evidence for CYCLIN-D1 protein expression. Presence of a t(11;14) did not show significant correlations with standard laboratory and clinical MM features including type of the paraprotein, hemoglobin, creatinine, LDH, albumine, calcium, CRP, and beta-2-microglobulin (b2M). In contrast to a recent report, there was also no association with CD20 expression by MM cells. With respect to survival, presence of any 14q-translocation (52% of patients) was associated with similar overall survival times (OS) compared to patients lacking a t(14q), whereas patients with a t(11;14) experienced prolonged OS (median, 70+ months vs. 59.8 months among patients without t(11;14); P = .071). This survival advantage was even greater among the 16 patients with t(11;14) who were also normal for 13q (P = .02); however, occurrence of a del(13q) concomitantly with a t(11;14) was indicative for shortened progression-free survial (17.7 months vs. 31.6 months; P = .17) and OS (P = .07). A survival benefit of MM patients with a t(11;14) was particularly evident for the population receiving standard-dose chemotherapy (median OS not yet reached; P = .02). By multivariate Cox regression analysis, low serum b2M at diagnosis (P = .001), absence of a del(13q) (P = .004), high-dose therapy (P = .034), and presence of t(11;14)/no del(13q) (P = .069) emerged as independent favorable parameters for OS. Thus, according to the cytogenetic pattern, three prognostic groups of patients could be discriminated (P < .001): patients with good [t(11;14), no del(13q)], intermediate [no t(11;14), no del(13q)], and poor prognosis [no t(11;14), del(13q)]. We conclude that MM with t(11;14) represents a heterogenous entity, and only the cytogenetic pattern t(11;14)/no del(13q) characterizes the most favorable prognostic group of MM, with sensitive disease to multiple lines of anti-MM therapy.

Abstract Glutathione S-transferase P1 (GSTP1) is a phase 2 drug metabolism enzyme involved in the metabolism and detoxification of a range of chemotherapeutic agents. A single nucleotide polymorphism (Ile105Val) results in a variant enzyme with lower thermal stability and altered catalytic activity. We hypothesized that patients with the less stable variant have a decreased ability to detoxify chemotherapeutic substrates, including melphalan, and have an altered outcome following treatment for multiple myeloma. We have assessed the impact of GSTP1 codon 105 polymorphisms in 222 patients entered into the Medical Research Council (MRC) myeloma VII trial (comparing standard-dose chemotherapy with high-dose therapy). In the standard-dose arm, patients with the variant allele (105Val) had an improved progression-free survival (PFS) (adjusted hazard ratios for PFS were 0.55 for heterozygotes and 0.52 for 105Val homozygotes, compared with 105Ile homozygotes; P for trend = .04); this was supported by a trend to improved overall survival, greater likelihood of entering plateau and shorter time to reach plateau in patients with the 105Val allele. No difference in outcome by genotype was found for patients treated with high-dose therapy. However, the progression-free survival advantage of the high-dose arm was seen only in patients homozygous for 105Ile (P = .008). (Blood. 2003;102:2345-2350)

Abstract Abstract 1639 Introduction: Maintenance using interferon-α (IFN) had previously been shown to be effective in indolent lymphoma (Solal-Celigny et al., NEJM 1993, Hagenbeek et al., JCO 1998). However, data on the impact of IFN in lymphoplasmacytic lymphoma (LPL) and after immuno-chemotherapy are rare. In two GLSG first-line trials which included LPL patients, IFN-maintenance was intended in all patients responding to induction therapy and not assigned to high-dose therapy. We performed a retrospective analysis to compare the clinical outcome in LPL patients who received IFN-maintenance versus no consolidation or maintenance. We adjusted for potential confounders that might have influenced the decision not to start IFN-maintenance. Methods: In the GLSG first-line trials “CHOP vs. MCP” and “CHOP vs. R-CHOP” patients younger than 60 years had been randomized between consolidating high-dose radio-chemotherapy followed by autologous stem cell transplantation (ASCT) and IFN-maintenance. IFN-maintenance was also intended in all responding patients older than 60 years. Patients with LPL achieving a partial or complete remission after MCP, CHOP, or R-CHOP and who did not start ASCT were included in the current analysis. We compared patients in which IFN-maintenance was not started to patients with IFN-maintenance. We investigated patient and treatment characteristics of these groups in order to detect possible reasons why IFN-maintenance was not started. Outcome parameters were remission duration (RD) and overall survival (OS). RD, calculated from the end of induction to relapse or death, was censored at the latest follow-up date in patients without event, but also when a new antilymphoma therapy was initiated without any sign of progression. No censoring was done for any form of dose reduction or stopping of IFN, which was recommended in the trials if inacceptable side effects were observed. RD and OS were analysed by Kaplan-Meier curves and log rank test and we adjusted for potential confounders in multiple Cox-Regression. In order to assess the impact of IFN-maintenance after R-containing induction, we performed a subgroup analysis of R-CHOP treated patients. Results: IFN-maintenance was started in 56 (75%) of 75 responding LPL patients not treated with high-dose therapy. Patients with IFN-maintenance were younger (60 vs. 69 years, p=0.001), but other baseline characteristics (ECOG performance status, haemoglobin, LDH, platelets, β2-microglobulin, IgM) were comparable, as well as the percentage of patients with R-CHOP induction (64% vs. 63%). More patients treated with IFN had achieved a CR (18% vs. 0%). Patients with IFN-maintenance had significantly longer RD (hazard ratio, HR, 0.27, 95% CI 0.12 to 0.59, p=0.001) and OS (HR 0.19, 95% CI, 0.06 to 0.58, p=0.004) which was similarly seen after adjustment for age (RD: 0.32, 95% CI 0.14 to 0.78, p=0.012, OS: 0.30, 95% CI 0.08 to 1.04, p=0.058), or the achievement of a CR. Of 48 patients responding to R-CHOP, IFN-maintenance was started in 36 (75%). RD after 3 years was 87% vs. 41% (p<0.001) and the HR for IFN adjusted for age were 0.19 for RD (95% CI 0.06 to 0.66 p=0.009) and 0.21 for OS (95% CI 0.04 to 1.05, p=0.058). Conclusions: Although this is a non-randomized comparison based on a relatively small patient number, our results suggest that IFN-maintenance is effective in LPL also in the era of immuno-chemotherapy. It seems relevant to keep in mind that interferon-a may be a therapeutic option when other strategies are not possible. It may also be relevant for future investigations in lymphoma therapy.

Abstract Between August 1990 and August 1995, 231 patients (median age 51, 53% Durie-Salmon stage III, median serum β-2-microglobulin 3.1 g/L, median C-reactive protein 4 g/L) with symptomatic multiple myeloma were enrolled in a program that used a series of induction regimens and two cycles of high-dose therapy (“Total Therapy”). Remission induction utilized non–cross-resistant regimens (vincristine-doxorubicin-dexamethasone [VAD], high-dose cyclophosphamide and granulocyte-macrophage colony-stimulating factor with peripheral blood stem cell collection, and etoposide-dexamethasone-cytarabine-cisplatin). The first high-dose treatment comprised melphalan 200 mg/m2 and was repeated if complete (CR) or partial (PR) remission was maintained after the first transplant; in case of less than PR, total body irradiation or cyclophosphamide was added. Interferon--2b maintenance was used after the second autotransplant. Fourteen patients with HLA-compatible donors underwent an allograft as their second high-dose therapy cycle. Eighty-eight percent completed induction therapy whereas first and second transplants were performed in 84% and 71% (the majority within 8 and 15 months, respectively). Eight patients (3%) died of toxicity during induction, and 2 (1%) and 6 (4%) during the two transplants. True CR and at least a PR (PR plus CR) were obtained in 5% (34%) after VAD, 15% (65%) at the end of induction, and 26% (75%) after the first and 41% (83%) after the second transplants (intent-to-treat). Median overall (OS) and event-free (EFS) survival durations were 68 and 43 months, respectively. Actuarial 5-year OS and EFS rates were 58% and 42%, respectively. The median time to disease progression or relapse was 52 months. Among the 94 patients achieving CR, the median CR duration was 50 months. On multivariate analysis, superior EFS and OS were observed in the absence of unfavorable karyotypes (11q breakpoint abnormalities, -13 or 13-q) and with low β-2-microglobulin at diagnosis. CR duration was significantly longer with early onset of CR and favorable karyotypes. Time-dependent covariate analysis suggested that timely application of a second transplant extended both EFS and OS significantly, independent of cytogenetics and β-2-microglobulin. Total Therapy represents a comprehensive treatment approach for newly diagnosed myeloma patients, using multi-regimen induction and tandem transplantation followed by interferon maintenance. As a result, the proportion of patients attaining CR increased progressively with continuing therapy. This observation is particularly important because CR is a sine qua non for long-term disease control and, eventually, cure.
