Abstract
While initial therapies have become highly effective with introduction of lenalidomide and bortezomib and patients may opt for delayed stem cell transplantation, it is important to collect stem cells for future transplant. Given its increasing use as initial therapy, we examined if lenalidomide had any impact on the ability to collect peripheral blood stem cells (PBSC). We studied the entire cohort of patients with myeloma undergoing PBSC mobilization at our institution during a 5-year period, comparing the results between patients receiving different initial therapies. Among those mobilized with granulocyte-colony stimulating factor (G-CSF) alone, there was a significant decrease in total CD34(+) cells collected (P<0.001), average daily collection (P<0.001), day 1 collection (P<0.001) and increased number of aphereses (P=0.004) in patients treated with lenalidomide compared to those receiving dexamethasone, thalidomide-dexamethasone or VAD. A similar trend was seen in those mobilized with chemotherapy and G-CSF. A trend was seen towards decreased PBSC yield with increasing duration of lenalidomide therapy as well as increasing age (P=0.002). There was no effect on quality of PBSC collected based on similar engraftment across all groups. We recommend collection of PBSC within 6 months of initiation of therapy with lenalidomide containing regimens to minimize the risk of mobilization failures.

Abstract
8105 Background: IL-6 is the central myeloma growth factor and we have shown that abnormal production of IL-1beta in the myeloma microenvironment stimulates the generation of paracrine IL-6. A Phase II trial was completed using IL-1ra, which inhibits paracrine IL-6 production, and low dose Dexamethasone (Dex), which decreases IL-1 levels through myeloma cell apoptosis, in patients with smoldering/indolent MM (SMM/IMM). These patients are at the greatest risk for progression to active MM and most likely to benefit from anti- cytokine therapy. Methods: Patients that had ≥ 10% bone marrow plasma cells and/or an IgG or IgA M-spike ≥ 3 g/dL and did not require immediate chemotherapy were eligible. A total of 47 patients received 100 mg of IL-1ra SQ qd for 6 months unless clinical progression occurred. Responding patients were allowed to continue on therapy with IL-1ra alone. Low dose Dex (20 mg qweek) was added after 6 months of IL-1ra in non-responding patients. The primary endpoint was progression-free survival (PFS). Results: The 47 patients were at high risk for progression to active MM with 98% having ≥ 10% plasma cells, 89% generating IL-1 levels consistent with myeloma (≥ 1.0), and 32% having bone lesions. All 47 patients received IL-1ra initially and 25/47 subsequently received IL-1Ra/Dex. For the group of 47 patients, the median overall progression-free survival was 37.5 months. Three patients achieved a minor response (MR) to Anakinra alone; 5 pts achieved a PR and 4 patients an MR after addition of Dex. Seven patients had a decrease in the plasma cell labeling index (PCLI; a marker of myeloma cell growth) on Anakinra alone which paralleled a decrease in the high sensitivity CRP (a marker of serum IL-6 levels). The median PFS for patients without (n=12) and with (n=35) a ≥ 15% decrease in their baseline hsCRP was 6 months and > 3 yrs, respectively (p=0.002). Conclusions: In SMM/IMM patients at high risk for progression to active myeloma, treatment with IL-1 inhibitors (IL-1ra ± Dex) results in an increased PFS in patients that demonstrate a ≥15% reduction in the baseline CRP compared to those that do not respond.

Abstract
3587 Background: The Insulin like Growth Factor I receptor (IGF-IR), a tyrosine kinase, is widely expressed in human tissues. IGF- IR and its ligands (IGF-I and IGF-II) are expressed by many human cancers (e.g., breast, prostate, colorectal and non-small cell lung). Binding of the ligands to the IGF-IR activates key cellular signaling pathways important for stimulating cellular proliferation and inhibiting apoptosis. IGF- I and IGF-II are present in the circulation, but also locally expressed in neoplastic tissue. Bioavailability of these ligands is regulated by a family of IGF binding proteins (IGFBPs1–6). CP-751,871, a fully human monoclonal antibody, is a highly specific and potent inhibitor of IGF-IR activation. In vitro experiments show that binding of CP 751,871 to IGF-IR induces receptor internalization and degradation. This antibody has been shown to have antineoplastic activity using both in vivo and in vitro pre-clinical models. Methods: Blood samples were collected for characterization of the pharmacokinetic and pharmacodynamic properties of CP-751,871 in phase 1 trials of this agent given to cancer patients either alone or in combination with chemotherapy. The endpoints assessed included among others: CP-751,871 plasma concentrations, total and free IGF-I, IGFBP-3, soluble IGF-IR and IGF-IR expression on granulocytes and tumor cells. Results: CP 751,871 exposure increased with dose over the 800-fold dose range investigated. Pharmacokinetic profiles were consistent with target-mediated disposition. A dose-dependent downregulation of soluble IGF-IR serum concentration and IGF-IR expression was observed, with sustained inhibition for the entire dosing period (3–4 week cycles) observed at doses ≥ 1.5 mg/kg. As predicted for an agent that interferes with IGF-I action, IGF-I and IGFBP-3 serum levels were up-regulated in a similar dose-dependent manner. Conclusions: The pharmacodynamic endpoints of clinical trials provide evidence that CP-751,871 targets IGF-IR in granulocytes, tumor cells and tissues involved in regulation of the growth hormone -IGF-I axis. These data provide proof of principle for the use of CP-751,871 as a first-in-class therapeutic approach to inhibit the IGF-IR pathway in cancer patients.

Abstract
8022 Background: Autologous stem cell transplant (ASCT) is the standard approach for eligible patients (pts) with multiple myeloma (MM). The median time to relapse after early ASCT is 2–3 yrs and overall survival (OS) is 4–5 yrs. Though various risk factors have been identified for early relapse, the outcome of this group of pts is not clearly described. With the advent of newer therapies, it is important to understand the natural history of MM in these pts to design treatment strategies. Methods: A total of 432 pts with MM, undergoing ASCT within 12 months (mos) of diagnosis, with a minimum follow up of 12 mos were studied. Clinical and laboratory data were obtained from a prospectively maintained database and clinical records. Pts were divided into 2 groups: early relapse (relapse <12 mos from ASCT) and late relapse (either relapsed >12 mos after ASCT or disease free at last follow up). Results: There were 94 pts (22%) in the early relapse group and among the late relapse group (N=338), 171 had relapsed beyond 12 mos and 167 were disease free at last follow up. The median time to ASCT was similar in all groups. The early relapse group had a significantly shorter median OS from diagnosis (23.9 vs. 82.2 months; P < 0.001) and from transplant (17.6 mos vs. not reached; P < 0.001). The median OS from relapse was 7.9 mos in this group compared to 39.6 months for the rest. In univariate analysis, elevated CRP, high BM plasma cell%, labeling index (PCLI) >1%, abnormal cytogenetics, presence of circulating PCs at harvest and lack of CR from ASCT predicted for early relapse. In multivariate analysis, an elevated PCLI (RR=2.9; P=0.002) and failure to achieve CR (RR 2.7; P=0.002) was associated with early relapse. Conclusions: Pts who relapse within 12 mos of an ASCT have a very short survival and should be offered trials evaluating novel therapies and combinations. Survival figures from this study represent the benchmark for the comparison of novel approaches in this population. Pts with poor prognostic factors have a short PFS after ASCT and should be considered for alternative approaches. Inability to achieve CR appears to predict shorter PFS and clinical trials evaluating maintenance therapy should be offered in these pts. No significant financial relationships to disclose.

Abstract
High-dose chemotherapy with stem cell transplantation (SCT) is feasible for elderly patients and patients with renal insufficiency. However, the impact of treatment on this patient population is unclear. We evaluated 678 consecutive patients with multiple myeloma who underwent SCT at Mayo Clinic. The complete response rate, time to progression and overall survival was recorded. Patients were stratified according to age (< or =65 or >65 years) and serum creatinine value at the time of transplantation (< or =2 or >2 mg/dl). Patient age did not have an effect on any outcome measure. Creatinine level did not affect complete response rate and time to progression, but patients with creatinine levels above 2 mg/ml had a higher day-100 mortality rate and a shorter overall survival rate. Platelet engraftment was also significantly delayed for patients with renal insufficiency. Selected patients over age 65 years may have outcomes identical to that of younger patients. When compared with patients with creatinine levels less than 2 mg/ml, patients with elevated creatinine levels had similar response rates and time to progression, but their overall survival was inferior. Transplantation should be offered to selected patients over age 65 years or selected patients with creatinine elevation.

Abstract
Clinical outcomes for multiple myeloma (MM) are highly heterogeneous and it is now clear that pivotal genetic events are the primary harbingers of such variation. These findings have broad implications for counseling, choice of therapy and the design and interpretation of clinical investigation. Indeed, as in acute leukemias and non-hodgkins lymphoma, we believe it is no longer acceptable to consider MM a single disease entity. As such, the accurate diagnosis of MM subtypes and the adoption of common criteria for the identification and stratification of MM patients has become critical. Herein, we provide a consensus high-risk definition and offer practical guidelines for the adoption of routine diagnostic testing. Although acknowledging that more refined classifications will continue to be developed, we propose that the definition of high-risk disease (any of the t(4;14), t(14;16), t(14;20), deletion 17q13, aneuploidy or deletion chromosome 13 by metaphase cytogenetics, or plasma cell labeling index >3.0) be adopted. This classification will identify most of the 25% of MM patients for whom current therapies are inadequate and for whom investigational regimens should be vigorously pursued. Conversely, the 75% of patients remaining have more favorable outcomes using existing - albeit non-curative - therapeutic options.

Abstract
Fluorescence in situ hybridisation (FISH) is an effective technique for the cytogenetic analysis of Waldenström macroglobulinemia (WM), but the potential impact of molecular cytogenetics on disease evolution and as a prognostic marker is still unknown. Deletion of the long arm of chromosome 6 (6q-) is the most frequent cytogenetic abnormality in WM. This study analysed the prevalence of this aberration in 102 WM patients, and correlated it with disease characteristics. The incidence of 6q21 deletion was 7% by conventional cytogenetics and 34% when analysed by FISH (54% when cytoplasmic immunoglobulin M-FISH was used). Patients with deletion of 6q displayed features of adverse prognosis, such as higher levels of beta2-microglobulin and monoclonal paraprotein and a greater tendency to display anaemia and hypoalbuminemia. Interestingly, there was a correlation between the presence of 6q deletion and the International Staging System prognostic index (incidence of 6q- among patients stratified in stages 1, 2 and 3 was 24%, 42% and 67% respectively). Those patients diagnosed with smouldering WM who displayed the abnormality showed a trend to an earlier requirement of treatment. Finally, the survival analysis did not show differences between the two groups of patients, probably due to the short follow up of our series.

Abstract
A specific role for increased level of expression of CKS1B, as a consequence of chromosome 1q21 copy number gain, has been postulated as both pathogenic, as well as a powerful clinical prognostic factor in multiple myeloma (MM). The purpose of this study is to determine the clinical associations and prognostic impact of copy number gain at chromosome 1q21 (with a bacteria artificial chromosome clone containing CKS1B) and CKS1B gene level of expression in MM. We studied the chromosome region 1q21 for copy number change in a cohort of myeloma patients treated by high-dose therapy with stem-cell rescue (HDT) (n = 159). A separate cohort of patients, treated by HDT was studied for CKS1B messenger RNA expression by gene expression profiling (n = 67). 1q21 gain was then correlated with clinical parameters and survival. Gain of 1q21 copy number was detected in about a third of MM and was associated with more proliferative disease and poor-risk cytogenetic categories such as t(4;14), and chromosome 13 deletion. Both 1q21 gain and increase gene expression level were significantly associated with reduced survival. However, neither is an independent prognostic marker in MM on multivariate Cox proportional hazard analysis.

Abstract
Chromosomal hyperdiploidy is the defining genetic signature in 40-50% of myeloma (MM) patients. We characterize hyperdiploid-MM (H-MM) in terms of its clinical and prognostic features in a cohort of 220 H-MM patients entered into clinical trials. Hyperdiploid-myeloma is associated with male sex, kappa immunoglobulin subtype, symptomatic bone disease and better survival compared to nonhyperdiploid-MM (median overall survival 48 vs 35 months, log-rank P = 0.023), despite similar response to treatment. Among 108 H-MM cases with FISH studies for common genetic abnormalities, survival is negatively affected by the existence of immunoglobulin heavy chain (IgH) translocations, especially those involving unknown partners, while the presence of chromosome 13 deletion by FISH did not significantly affect survival (median overall survival 50 vs 47 months, log-rank P = 0.47). Hyperdiploid-myeloma is therefore a unique genetic subtype of MM associated with improved outcome with distinct clinical features. The existence of IgH translocations but not chromosome 13 deletion by FISH negatively impacts survival and may allow further risk stratification of this population of MM patients.

Abstract
To evaluate autologous stem cell transplant (ASCT) in older patients with intermediate grade non-Hodgkin's lymphoma (NHL), the Mayo Clinic Rochester BMT database was reviewed for all patients 60 years of age and older who received ASCT for NHL between September 1995 and February 2003. Factors evaluated included treatment-related mortality (TRM), event-free survival (EFS) and overall survival (OS). Ninety-three patients were identified, including twenty-four (26%) over the age of 70 years. Treatment-related mortality (5.4%) was not significantly different when compared to a younger cohort (2.2%). At a median follow-up of 14 months (0.6-87.6 months), the estimated median survival is 25 months (95% confidence interval (CI) 12-38) in the older group compared to 56 months (95% CI 37-75) (P=0.037) in the younger group. The estimated 4-year EFS was 38% for the older group compared to 42% in the younger cohort (P=0.1). By multivariate analysis, the only factor found to influence survival in the older group was age-adjusted International Prognostic Index at relapse, 0-1 better than 2-3 (P=0.03). Autologous stem-cell transplant can be safely performed in patients 60 years or older with chemotherapy sensitive relapsed or first partial remission NHL. The outcome may not be different from that of younger patients in terms of TRM and EFS.

Abstract
7605 Background: In the setting of autologous stem cell transplantation (ASCT) in multiple myeloma (MM), it has been shown that peripheral blood absolute lymphocyte count (ALC) on day 15 is an independent prognostic factor for clinical outcomes. Recently the International Staging System (ISS) for MM has been developed as a simple staging system to assess survival in newly diagnosed MM patients. The role of ALC on survival in newly diagnosed MM patients is unknown. Methods: Between 1994 and 2002, 1,835 consecutive MM patients were evaluated at the Mayo Clinic, Rochester. Of these patients, we retrospectively analyzed 584 MM patients that were originally diagnosed and followed at the Mayo Clinic. The primary end point was to assess the role of ALC at the time of MM diagnosis on overall survival (OS). OS was measured from the date of diagnosis to time of death or last follow-up. ALC was analyzed as a continuous variable and dichotomized based on finding the optimal cut point based on the log-rank statistic. ALC was then compared to the ISS. Results: The median age of the cohort was 67 years (range: 29–94 years), including 234 females and 350 males. The median follow-up was 32 months (range: 1–136 months). The median ALC at diagnosis was 1.2 x 109/L (range: 0.12–5.44 x 109/L). ALC, as a continuos variables was identified as a prognostic factor for OS (HR= 0.466, 95%CI= 0.396–0.547, p < 0.0001). MM patients with an ALC ≥ 1.3 x 109/L experienced a superior OS compared with MM patients with an ALC < 1.3 x 109/L (55.5 months versus 22.6 months, p< 0.0001). In the multivariate analysis, ALC was independent prognostic factor when compared to the ISS (HR = 0.580, 95%CI=0.518–0.647, p< 0.0001). Conclusions: Our study shows that ALC at diagnosis for MM is an independent prognostic factor for OS, suggesting how the host immune status plays a critical role in the survival of patients with MM.

Abstract
Prognosis in chronic myelomonocytic leukemia (CMML) is unfavorable and the optimal therapy remains uncertain. Currently, allogeneic stem cell transplantation is the only known curative therapeutic option. However, the data available are limited and restricted to small retrospective series. There is even less information on the use of donor lymphocyte infusions (DLI) for this disease. We reviewed our experience of allogeneic stem cell transplantation and DLI for adults with CMML. Seventeen consecutive adults underwent allogeneic stem cell transplantation from related (n=14) or unrelated (n=3) donors. Median age was 50 years (range 26-60). Seven patients (41%) demonstrated relapse or persistent disease at a median of 6 months (range 3-55.5). Five patients underwent DLI for morphologic relapse and one for mixed donor chimerism. Two patients achieved durable complete remissions of 15 months each. The overall transplant-related mortality was 41% (n=7). With a median follow-up of 34.5 months, three patients (18%) currently remain alive and in continuous CR. The current study demonstrates a graft-versus-leukemia effect in CMML, both for allogeneic stem cell transplantation and for DLI. Nevertheless, consistent with reported experience of others, overall outcomes remain less than optimal and unpredictable.

Abstract
Hyperdiploid and non-hyperdiploid multiple myeloma represents distinct biological entities characterized by different patterns of genetic changes. We sought to determine whether ploidy category (non-hyperdiploid versus hyperdiploid) remains stable over time from diagnosis to progression. Of the 43 patients studied (39 by flow cytometry DNA index and 4 by a FISH-based index), only five (12%) altered their ploidy status at progression. In three of these patients, the change may possibly be attributable to technical artifacts because of the low absolute change in DNA index. For those who retain their ploidy subtypes, the DNA index change minimally (3.75+/-4.87%). It would appear that the initiating genetic events underlying hyperdiploid and non-hyperdiploid MM that marks them out as distinct entities continue to dominate and persist during disease evolution and progression.

Abstract
High-dose chemotherapy and autologous stem cell transplantation are used increasingly to treat patients with light-chain-related amyloidosis (AL). Treatment-related mortality is approximately 15%. To enable more patients to undergo stem cell transplantation, a risk-adapted strategy has been developed to treat with lower chemotherapy doses those patients who are at excessive risk. It is unclear whether reducing the chemotherapy dose in patients at excessive risk of treatment toxicity reduces the overall response. We retrospectively reviewed 171 AL patients who underwent conditioning chemotherapy with stem cell transplantation. The patients comprised two groups: those receiving standard high-dose melphalan and those receiving intermediate-dose melphalan. Responses were categorized as hematologic response, which used criteria for myeloma response. The two groups showed statistically significant differences; the overall response rates were 75% in the high-dose group and 53% in the intermediate-dose group although treatment-related mortality was the same in both groups. Reducing the melphalan dose appeared to render more AL patients eligible for stem cell transplantation but sacrificed an element of response. Methods are needed to reduce treatment-related toxicity so that more patients can receive full-dose conditioning chemotherapy.

Abstract
Given the survival advantage, high-dose therapy (HDT) remains the standard of care for patients with multiple myeloma eligible for the procedure. For those undergoing HDT, initial therapy aimed at reducing tumor burden is given prior to stem cell harvest. Various regimens, mostly variations of VAD (vincristine, doxorubicin, dexamethasone), are used for induction therapy. We retrospectively evaluated if single agent dexamethasone would be an effective induction therapy, given that it is the most active drug in these combinations. A total of 35 patients who received induction therapy with dexamethasone alone were compared to a similar group of 72 patients who received VAD as the initial therapy. We found a 63% response rate with dexamethasone compared to 74% with VAD (P=0.25). Including minimal responses, the overall response rate for Dex and VAD was 74 and 86%, respectively (P=0.13). The overall and complete response rates to transplant, respectively, were 97 and 26% for the dexamethasone group and 100 and 39% for the VAD group; P=0.33 and 0.18. No significant differences were observed in the progression-free and overall survival at 1 year post transplant. Single agent dexamethasone appears to be an effective alternative to VAD for induction therapy prior to HDT in myeloma.

Abstract
Autologous stem cell transplant (SCT) improves survival in multiple myeloma (MM) and remains the standard of care for eligible patients. Nearly a third of patients with newly diagnosed MM fail initial therapy aimed at reducing tumor burden preceding SCT (primary refractory). It is unclear if an initial response is important for successful SCT. We evaluated our experience with SCT in 50 patients with primary refractory MM and compared it to 101 patients with chemosensitive disease receiving SCT. The study cohort had a median age of 56 years (range 29-72) consisting of 87 males (58%). A total of 46 patients (92%) in the refractory group and 100 (99%) in the chemosensitive group had a response to transplant (50% or greater reduction in the M-protein). In all, 10 refractory patients (20%) and 35 (35%) in the chemosensitive group achieved a CR (P=0.06). The 1-year estimated progression-free survival from the time of transplant for the refractory group was 70% compared to 83% for the chemosensitive group (P=0.65). The lack of response to initial induction therapy does not appear to preclude a good response to SCT. We recommend that patients with primary refractory MM be offered early SCT.

Abstract
Despite response rates of 30% after high-dose chemotherapy with autologous hematopoietic stem cell transplant, patients with multiple myeloma are not cured. 153Samarium ethylenediaminetetramethylenephosphonate (153Sm-EDTMP; Quadramet) is a short-range, beta-emitting therapeutic radiopharmaceutical with avid skeletal uptake. In total, 12 patients were treated with escalating doses of 153Sm-EDTMP (N=3/group; 6, 12, 19.8, and 30 mCi/kg) and a fixed dose of melphalan (200 mg/m(2)). No dose limiting toxicity was seen. To better standardize the marrow compartment radiation dose, the study was modified such that an additional six patients were treated at a targeted absorbed radiation dose to the red marrow of 40 Gy based on a trace labeled infusion 1 week prior to the therapy. Despite rapid elimination of unbound radiopharmaceutical via kidneys and bladder, no episodes of nephrotoxicity, hemorrhagic cystitis, or delayed radiation nephritis were observed with a median follow-up of 31 months (range 8.5-44). Median times to ANC>0.5 and platelet >20 x 10(6)/l were 12 and 11 days, respectively, with no graft failures. Overall response rate was 94% including seven very good partial responses and five complete responses. Addition of 153Sm EDTMP to melphalan conditioning appears to be safe, well-tolerated and worthy of further study.

Abstract
Absolute lymphocyte count at day 15 (ALC-15) after autologous peripheral blood hematopoietic stem cell transplantation (APHSCT) is an independent prognostic factor for survival in multiple myeloma (MM); however, factors affecting ALC-15 in MM remain unknown. We hypothesized that the dose of infused peripheral blood autograft lymphocytes (autograft absolute lymphocyte count: A-ALC) impacts ALC-15 recovery. Between 1989 and 2001, 267 consecutive MM patients underwent APHSCT. We set out to determine the correlation between A-ALC and ALC-15 and the utility of A-ALC as a marker for ALC-15 recovery. A-ALC was found to be both a strong predictor for area under curve (AUC=0.93; P=0.0001) and strongly correlated with (r(s)=0.83; P=0.0001) ALC-15 recovery. Higher infused A-ALC was significantly correlated with an ALC-15>/=500/microl. In addition, median post-transplant overall survival (OS) and time to progression (TTP) were longer in patients who received an A-ALC>/=0.5 x 10(9) lymphocytes/kg versus A-ALC <0.5 x 10(9) lymphocytes/kg (58 vs 30 months, P=0.00022; 22 vs 15 months, P<0.00012, respectively). Multivariate analysis demonstrated A-ALC as an independent prognostic indicator for OS and TTP. These results indicate that an infused dose of autograft lymphocytes significantly impacts clinical outcome post-APHSCT in MM.

Abstract
Bone marrow (BM) angiogenesis is increased in multiple myeloma and is an important prognostic factor. However, prior studies were mainly done on patients receiving conventional chemotherapy and there is limited data on its prognostic value in patients undergoing high-dose therapy (HDT) as initial therapy. We studied BM angiogenesis in terms of microvessel density (MVD) in 88 newly diagnosed patients, who were uniformly treated, with 3-4 cycles of induction chemotherapy followed by HDT. We examined if MVD at diagnosis was predictive of response to induction therapy or to subsequent HDT. In addition, we also examined its prognostic value in these patients. The median MVD for primary refractory patients was 28 (range, 2-84) compared to 27 (range, 2-99) for responding patients (P=0.7). The median progression-free survival (PFS) was 21 months for those with high-grade angiogenesis compared to 42 months for those with low-grade angiogenesis, P=0.017. The median overall-survival (OS) from diagnosis was 40 months for those with high-grade angiogenesis and not yet reached, for those with low-grade angiogenesis, P=0.007. BM MVD at the time of initial diagnosis is an important prognostic factor for OS and PFS in patients undergoing autologous transplantation as frontline therapy for myeloma.

Abstract
Bone marrow (BM) angiogenesis is increased in multiple myeloma and is an important prognostic factor for survival. Previous studies have shown that BM angiogenesis does not change following chemotherapy or stem cell transplant. Given its potential antiangiogenic effect, we evaluated if thalidomide therapy would affect the BM microvessel density (MVD). We studied BM angiogenesis in 81 patients with various disease stages treated with thalidomide with or without dexamethasone. MVD was determined as previously described. MVD was compared between pretreatment marrows and those obtained 4-6 months following therapy. The median (range) MVD pretherapy was 28 (2-116) and post-therapy was 15 (3-97). A partial or complete response was seen in 58% of patients, stable disease in 41% and progressive disease in one patient. MVD decreased significantly in responders (median decrease of 12, P<0.001). In contrast, no significant change in MVD was seen in those failing to respond to thalidomide. Unlike the lack of resolution of angiogenesis reported with other therapies, we demonstrate for the first time a significant decrease in microvessels with thalidomide therapy. Although not conclusive, this result lends further support to the hypothesis that angiogenesis is a relevant therapeutic target in myeloma.

Abstract
The purpose of this study was to determine the effect of thalidomide on stem cell collection and engraftment in patients with multiple myeloma. We performed a retrospective review of 67 patients newly diagnosed with multiple myeloma at Mayo Clinic and treated with a single regimen prior to stem cell transplantation between January of 2000 and September of 2001. Stem cells were collected from 24 patients who received thalidomide, 200 mg/day, with dexamethasone as initial therapy before stem cell collection. These patients were compared with 43 control patients seen during the same period who had received only one previous regimen before stem cell collection and transplantation. The cumulative thalidomide dose before stem cell collection was 17 000 mg over a median of four cycles (range, 2-7 cycles). The thalidomide and control groups were not significantly different in their baseline characteristics, number of stem cells collected, time to collection, or time to engraftment of neutrophils or platelet count of 50 000/microl. Time to platelet count of 20 000/microl was delayed by a median of 4 days (P=0.008), but platelet transfusion requirements did not differ (P=0.95). We concluded that thalidomide does not substantially affect peripheral cell mobilization or engraftment.

Abstract
Allogeneic blood and marrow transplantation (BMT) is curative for many patients with high-risk and relapsed acute lymphoblastic leukemia (ALL). However, relapse is an important cause of post-transplantation failure, and there are no reliable markers to predict relapse. A retrospective review of patients with ALL who underwent matched related allogeneic BMT was carried out to examine whether the rate of lymphocyte recovery after transplantation had any prognostic value in ALL. The absolute lymphocyte count (ALC) at days 21 and 30 after transplantation was obtained for 43 patients who received transplants during an 18-year period. Patients with an ALC of 175 x 10(6)/l or less on day 21 were more likely to relapse than those with ALC greater than 175 x 10(6)/l (relative risk, 4; 95% confidence interval, 1.5-11.2). Patients with slower lymphocyte recovery had significantly lower relapse-free survival than those with faster recovery (P=0.0028). There was also a trend toward poorer overall survival among those with a slow lymphocyte recovery (log-rank test; P=0.028). The rate of lymphocyte recovery is prognostic in patients with ALL undergoing allogeneic BMT, and this should be integrated with other predictors to identify patients at high risk of relapse. Such patients could be considered for interventions aimed at prevention of relapse, including rapid withdrawal of immunosuppressive medication or donor lymphocyte infusion.

Abstract
Secondary myelodysplastic syndrome (sMDS) and acute myelogenous leukemia (AML) have been recognized with increasing frequency following autologous stem cell transplantation (ASCT). A retrospective analysis of 230 consecutive patients with Hodgkin's lymphoma (HL, 64) and non-Hodgkin's lymphoma (NHL, 166) who underwent ASCT was conducted to assess the incidence and risk factors for the development of sMDS/AML. At a median follow up of 41 months (range 0.1-177 months), 10 of 230 patients (4.3%) developed sMDS/AML. The 5-year-actuarial incidence of sMDS/AML was 13.1% and 5-year cumulative incidence by competing risk analysis was 4.2%. The median time to development of sMDS/AML was 39.9 months from the time of ASCT (range 12.1-62.0 months). Complex karyotypes at diagnosis of sMDS/AML included structural anomalies and/or loss of chromosome 5 (eight patients), 7 (five patients), 17 (two patients) and 20 (two patients). All patients subsequently died, at a median of 6.8 months (range 0-39.9) from diagnosis of sMDS/AML. Fluorescent in situ hybridization (FISH) analysis for -5/5q- and -7/7q- were normal in all six patients whose pre-ASCT bone marrow was available for testing. Five of the six had samples available for testing at diagnosis of sMDS/AML and all had abnormal FISH results. By univariate statistical analysis, male gender (P=0.01), prior alkylating agents (mechlorethamine for HL, P=0.001 and cyclophosphamide for NHL, P=0.05) and the number of prior treatment regimens (P=0.04) were significantly associated with the development of sMDS/AML. Given the relatively low incidence rate of sMDS/AML, these analyses are primarily exploratory in nature but provide some insight into relevant risk factors and illustrate the risk of developing sMDS/AML after myeloablative conditioning and ASCT for lymphoma.
