Triplet Therapy, Transplantation, and Maintenance until Progression in Myeloma.

BACKGROUND: In patients with newly diagnosed multiple myeloma, the effect of adding autologous stem-cell transplantation (ASCT) to triplet therapy (lenalidomide, bortezomib, and dexamethasone [RVD]), followed by lenalidomide maintenance therapy until disease progression, is unknown. METHODS: In this phase 3 trial, adults (18 to 65 years of age) with symptomatic myeloma received one cycle of RVD. We randomly assigned these patients, in a 1:1 ratio, to receive two additional RVD cycles plus stem-cell mobilization, followed by either five additional RVD cycles (the RVD-alone group) or high-dose melphalan plus ASCT followed by two additional RVD cycles (the transplantation group). Both groups received lenalidomide until disease progression, unacceptable side effects, or both. The primary end point was progression-free survival. RESULTS: Among 357 patients in the RVD-alone group and 365 in the transplantation group, at a median follow-up of 76.0 months, 328 events of disease progression or death occurred; the risk was 53% higher in the RVD-alone group than in the transplantation group (hazard ratio, 1.53; 95% confidence interval [CI], 1.23 to 1.91; P<0.001); median progression-free survival was 46.2 months and 67.5 months. The percentage of patients with a partial response or better was 95.0% in the RVD-alone group and 97.5% in the transplantation group (P = 0.55); 42.0% and 46.8%, respectively, had a complete response or better (P = 0.99). Treatment-related adverse events of grade 3 or higher occurred in 78.2% and 94.2%, respectively; 5-year survival was 79.2% and 80.7% (hazard ratio for death, 1.10; 95% CI, 0.73 to 1.65). CONCLUSIONS: Among adults with multiple myeloma, RVD plus ASCT was associated with longer progression-free survival than RVD alone. No overall survival benefit was observed.

A Pilot Study of Lenalidomide Maintenance Therapy after Autologous Transplantation in Relapsed or Refractory Classical Hodgkin Lymphoma.

For patients with relapsed or refractory classical Hodgkin lymphoma (cHL), salvage chemotherapy followed by consolidation with autologous stem cell transplant (ASCT) remains the standard of care. Even with this aggressive treatment strategy, 5-year progression-free survival is ≤50%, and there remains interest in maintenance strategies to improve long-term disease-free survival. Lenalidomide is an immunomodulatory agent with demonstrated activity in multiple subtypes of lymphoma including cHL, and has also been shown to improve both progression-free and overall survival as maintenance therapy after ASCT in multiple myeloma. This multicenter study evaluated maintenance lenalidomide after ASCT for patients with cHL. Patients were enrolled 60 to 90 days post-transplant and received oral lenalidomide on days 1 to 28 of 28-day cycles for a maximum of 18 cycles. Lenalidomide was started at 15 mg daily and increased to maximum of 25 mg daily if tolerated. The primary objective of this study was to assess the feasibility of this regimen, with a goal <30% rate of discontinuation at or before cycle 12 for drug-related reasons. Twenty-seven patients were enrolled and 26 received at least 1 dose of lenalidomide. With a median follow-up of 51.3 months (range, 12.2 to 76.2 months), 23 of 26 patients were alive. Median event-free survival was 9.4 months and median progression-free survival had not been reached, with 17 of 26 patients (65.4%) remaining in remission at last follow-up. Excluding 4 patients who discontinued therapy for progression and 2 who discontinued due to noncompliance, the discontinuation rate at or before cycle 12 was 52%. Treatment was complicated by a high frequency of hematologic adverse events, with 15 patients (58%) experiencing grade 3 to 4 hematologic toxicity and 5 (19%) experiencing grade 4 hematologic toxicity. We conclude that the regimen of maintenance lenalidomide explored in this study is not feasible for patients with cHL immediately following ASCT. An alternative lenalidomide dose or schedule may be better tolerated following ASCT for patients with relapsed or refractory cHL.

A Phase I Study of CPI-613 in Combination with High-Dose Cytarabine and Mitoxantrone for Relapsed or Refractory Acute Myeloid Leukemia.

Purpose: CPI-613, a lipoate analogue that inhibits pyruvate dehydrogenase (PDH) and α-ketogluterate dehydrogenase (KGDH), has activity in patients with myeloid malignancies. This study explored the role of mitochondrial metabolism in chemotherapy response and determined the MTD, efficacy, and safety of CPI-613 combined with high-dose cytarabine and mitoxantrone in patients with relapsed or refractory acute myeloid leukemia.Experimental Design: The role of mitochondrial response to chemotherapy was assessed in cell lines and animal models. A phase I study of CPI-613 plus cytarabine and mitoxantrone was conducted in patients with relapsed or refractory AML.Results: Exposure to chemotherapy induced mitochondrial oxygen consumption that depended on PDH. CPI-613 sensitized AML cells to chemotherapy indicating that mitochondrial metabolism is a source of resistance. Loss of p53 did not alter response to CPI-613. The phase I study enrolled 67 patients and 62 were evaluable for response. The overall response rate was 50% (26CR+5CRi/62). Median survival was 6.7 months. In patients over 60 years old, the CR/CRi rate was 47% (15/32) with a median survival of 6.9 months. The response rate for patients with poor-risk cytogenetics also was encouraging with 46% (11/24 patients) achieving a CR or CRi. RNA sequencing analysis of a subset of baseline bone marrow samples revealed a gene expression signature consistent with the presence of B cells in the pretreatment marrow of responders.Conclusions: The addition of CPI-613 to chemotherapy is a promising approach in older patients and those with poor-risk cytogenetics.

Updated analysis of CALGB (Alliance) 100104 assessing lenalidomide versus placebo maintenance after single autologous stem-cell transplantation for multiple myeloma: a randomised, double-blind, phase 3 trial.

BACKGROUND: In the CALGB (Alliance) 100104 study, lenalidomide versus placebo after autologous stem-cell transplantation (ASCT) was investigated for patients with newly diagnosed myeloma. That study showed improved time to progression and overall survival and an increase in second primary malignancies for lenalidomide at a median follow-up of 34 months. Here we report an updated intention-to-treat analysis of CALGB (Alliance) 100104 at a median follow-up of 91 months. METHODS: Patients were eligible for this randomised, double-blind, placebo-controlled, phase 3 trial if they had symptomatic disease requiring treatment; had received, at most, two induction regimens; and had achieved stable disease or better in the first 100 days after ASCT. We randomly assigned patients to either lenalidomide or placebo groups using permuted block randomisation, with a fixed block size of six. Randomisation was stratified by three factors: normal or elevated ß2 microglobulin concentration at registration (≤2·5 mg/L vs >2·5 mg/L), previous use or non-use of thalidomide during induction therapy, and previous use or non-use of lenalidomide during induction therapy. The starting dose was two capsules (10 mg) per day, escalated to three capsules (15 mg) per day after 3 months. The primary endpoint was time to progression (time of progressive disease or death from any cause), with intention-to-treat analysis. This study is registered with ClinicalTrials.gov, identifier NCT00114101. New patients are no longer being recruited, but some patients remain on treatment and in follow-up. FINDINGS: Between April 14, 2005, and July 2, 2009, 460 patients were randomly assigned to receive either lenalidomide (n=231) or placebo (n=229). After three interim analyses, the study was unblinded at a median follow-up of 18 months, at which point 86 (67%) of 128 patients without progressive disease in the placebo group chose to cross over to the lenalidomide group. The median follow-up for the updated survival analysis, as of Oct 19, 2016, was 91 months (IQR 83·6-103·1). The median time to progression was 57·3 months (95% CI 44·2-73·3) for the lenalidomide group and 28·9 months (23·0-36·3) for the placebo group (hazard ratio 0·57, 95% CI 0·46-0·71; p<0·0001). The most common grade 3-4 adverse events were neutropenia (116 [50%] patients in the lenalidomide group and 41 [18%] patients in the placebo group) and thrombocytopenia (34 [15%] patients in the lenalidomide group and 12 [5%] patients in the placebo group). 18 (8%) haematological and 14 (6%) solid tumour second primary malignancies were diagnosed after randomisation and before disease progression in the lenalidomide group, compared with three (1%) haematological and nine (4%) solid tumour second primary malignancies in the placebo group. Three haematological and five solid tumour second primary malignancies in the placebo group were in the crossover subgroup. INTERPRETATION: Despite an increase in haematological adverse events and second primary malignancies, lenalidomide maintenance therapy after ASCT significantly improved time to progression and could be considered a standard of care.

Final Results of a Phase 1 Study of Vorinostat, Pegylated Liposomal Doxorubicin, and Bortezomib in Relapsed or Refractory Multiple Myeloma.

INTRODUCTION/BACKGROUND: Deacetylase inhibitors have synergistic activity in combination with proteasome inhibitors and anthracyclines in preclinical models of multiple myeloma (MM). We therefore evaluated the safety and efficacy of the deacetylase inhibitor vorinostat in combination with pegylated liposomal doxorubicin (PLD) and bortezomib in relapsed/refractory MM. PATIENTS AND METHODS: Thirty-two patients were treated with PLD and bortezomib in combination with escalating doses of vorinostat on days 4 to 11 or 1 to 14. RESULTS: The maximum tolerated dose of vorinostat was 400 mg on days 4 to 11. Neutropenia and thrombocytopenia attributable to protocol therapy were seen in 59% and 94% of patients, of which 37% and 47% were of grade 3 or higher severity, respectively. Constitutional and gastrointestinal adverse events of all grades were common, the majority of which were less than grade 3 in severity. The overall response rate (partial response rate or better) was 65% and the clinical benefit rate (minimal response rate or better) 74%. The overall response rate was 83%, 71%, and 45% for patients with bortezomib-naive, -sensitive, and -refractory MM, respectively. The median progression-free survival was 13.9 months and the 3-year overall survival 77%. Whole blood proteasome activity assays demonstrated a potential impact of vorinostat on the chymotryptic-like activity of the proteasome. CONCLUSION: Further evaluation of PLD, bortezomib, and deacetylase inhibitor combinations is warranted, with special attention directed toward strategies to improve tolerability.

Effect of ArginMax on sexual functioning and quality of life among female cancer survivors: results of the WFU CCOP Research Base Protocol 97106.

BACKGROUND: Problems with sexual functioning are common following therapy for breast and gynecologic cancers, although there are few effective treatments. OBJECTIVE: To assess the impact of ArginMax, a nutritional supplement comprised of extracts of L-arginine, ginseng, gingko, and damiana, as well as multivitamins and minerals, on sexual functioning and quality of life in female cancer survivors. METHODS: This was a 12-week, randomized, placebo-controlled trial of eligible patients who were 6 months or more from active treatment and reporting problems with sexual interest, satisfaction, and functioning after therapy. The participants took 3 capsules of Arginmax or placebo twice daily. Outcome measures were the Female Sexual Function Inventory (FSFI) and the Functional Assessment of Cancer Therapy - General (FACT-G). Assessments were done at baseline, 4, 8, and 12 weeks. RESULTS: 186 patients with a median age of 50 years were accrued between May 10, 2007 and March 24, 2010. 76% of the patients were non-Hispanic white. Most had breast or a gynecologic cancer (78% and 12%, respectively). At 12 weeks, there were no differences between the ArginMax group (n = 96) and placebo (n = 92) group in sexual desire, arousal, lubrication, orgasm,satisfaction or pain. However, FACT-G total scores were significantly better for participants who took ArginMax compared with those who took placebo (least squares [LS] means, 87.5 vs 82.9, respectively; P = .009). The Fact-G subscales that were most affected were Physical (25.37 vs. 23.51, P = .001) and Functional Well-Being (22.46 vs. 20.72, P = .007). Toxicities were similar for both groups. LIMITATIONS: Study results are limited by a lack of data on the participants' psychological and physical symptoms and sexual partner variables. CONCLUSIONS: ArginMax had no significant impact on sexual functioning, but patient quality of life was significantly better at 12 weeks in participants who received ArginMax.

Hematopoietic stem cell transplant candidate and designated proxy distress levels prior to hematopoietic stem cell transplantation.

Hematopoietic stem cell transplantation (HCT) is associated with a high risk of morbidity, making advance care planning (ACP) essential. The purpose of this study was to assess and compare proxy and HCT candidate distress levels (Distress Thermometer) before (T1) and after (T2) ACP question completion. 79 participants (40 HCT candidates, 39 proxies) rated their distress. The T1, T2 mean distress scores (SD) for HCT candidates were 3.13(2.27), 2.96(2.10); 43% and 38% endorsed clinically significant distress (≥4). Proxies reported 4.21(2.48), 4.33 (2.46); 62% endorsed significant distress at T1, T2. The majority of proxies endorsed distress levels that were clinically significant and comparatively higher (T1 (p = 0.047) and T2 (p = 0.009)) than their paired HCT recipients. Responding to questions about ACP did not increase overall distress ratings.

A phase II study of the oral VEGF receptor tyrosine kinase inhibitor vatalanib (PTK787/ZK222584) in myelodysplastic syndrome: Cancer and Leukemia Group B study 10105 (Alliance).

BACKGROUND: Angiogenesis is implicated in the pathophysiology and progression of myelodysplastic syndromes (MDS). Vatalanib (PTK787/ZK222584; Novartis and Schering AG) inhibits receptor tyrosine kinases of vascular endothelial growth factor, platelet derived growth factor and c-Kit. We examined whether vatalanib induces hematological responses in MDS and/or delays progression to acute myeloid leukemia (AML) or death. METHODS: Two cohorts were studied. Vatalanib 1250 mg orally was given once daily (cohort 1) or 750-1250 mg once daily in an intra-patient dose escalating schedule (cohort 2) in 28-day cycles to 155 patients with MDS; 142 patients were evaluable for response and 153 for toxicity. RESULTS: The median age was 70.5 years; 51 % had low risk (International Prognostic Scoring System {IPSS} Low/Intermediate-1) and 32 % had high risk (IPSS Intermediate-2/High) MDS. Hematological improvement was achieved in 7/142 (5 %) patients; all 7 were among the 47 patients able to remain on vatalanib for at least 3 months (hematological improvement achieved in 15 % of these 47 patients). For patients with low risk and high risk MDS, respectively, median progression-free survivals were 15 and 6 months, median times to transformation to AML were 28 and 6 months, and median overall survivals were 36 and 10 months. The most frequent non-hematological adverse events grade ≥ 2 were fatigue, nausea or vomiting, dizziness, anorexia, ataxia, diarrhea, and pain. Two deaths (one intra-cerebral hemorrhage and one sudden death) were possibly related to vatalanib. CONCLUSIONS: Vatalanib induces improvement in blood counts in a small proportion of MDS patients. Clinical applicability is limited by side effects.

Lenalidomide after stem-cell transplantation for multiple myeloma.

BACKGROUND: Data are lacking on whether lenalidomide maintenance therapy prolongs the time to disease progression after autologous hematopoietic stem-cell transplantation in patients with multiple myeloma. METHODS: Between April 2005 and July 2009, we randomly assigned 460 patients who were younger than 71 years of age and had stable disease or a marginal, partial, or complete response 100 days after undergoing stem-cell transplantation to lenalidomide or placebo, which was administered until disease progression. The starting dose of lenalidomide was 10 mg per day (range, 5 to 15). RESULTS: The study-drug assignments were unblinded in 2009, when a planned interim analysis showed a significantly longer time to disease progression in the lenalidomide group. At unblinding, 20% of patients who received lenalidomide and 44% of patients who received placebo had progressive disease or had died (P<0.001); of the remaining 128 patients who received placebo and who did not have progressive disease, 86 crossed over to lenalidomide. At a median follow-up of 34 months, 86 of 231 patients who received lenalidomide (37%) and 132 of 229 patients who received placebo (58%) had disease progression or had died. The median time to progression was 46 months in the lenalidomide group and 27 months in the placebo group (P<0.001). A total of 35 patients who received lenalidomide (15%) and 53 patients who received placebo (23%) died (P=0.03). More grade 3 or 4 hematologic adverse events and grade 3 nonhematologic adverse events occurred in patients who received lenalidomide (P<0.001 for both comparisons). Second primary cancers occurred in 18 patients who received lenalidomide (8%) and 6 patients who received placebo (3%). CONCLUSIONS: Lenalidomide maintenance therapy, initiated at day 100 after hematopoietic stem-cell transplantation, was associated with more toxicity and second cancers but a significantly longer time to disease progression and significantly improved overall survival among patients with myeloma.

Final results of a multicenter phase 1 study of lenalidomide in patients with relapsed or refractory chronic lymphocytic leukemia.

Based on clinical activity in phase 2 studies, lenalidomide was evaluated in a phase 2/3 study in patients with relapsed/refractory chronic lymphocytic leukemia (CLL). Following tumor lysis syndrome (TLS) complications, the protocol was amended to a phase 1 study to identify the maximum tolerated dose-escalation level (MTDEL). Fifty-two heavily pretreated patients, 69% with bulky disease and 48% with high-risk genomic abnormalities, initiated lenalidomide at 2.5 mg/day, with dose escalation until the MTDEL or the maximum assigned dose was attained. Lenalidomide was safely titrated to 20 mg/day; the MTDEL was not reached. Most common grade 3-4 adverse events were neutropenia and thrombocytopenia; TLS was mild and rare. The low starting dose and conservative dose escalation strategy resulted in six partial responders and 30 patients obtaining stable disease. In summary, lenalidomide 2.5 mg/day is a safe starting dose that can be titrated up to 20 mg/day in patients with CLL.

A phase 2 multicenter study of lenalidomide in relapsed or refractory classical Hodgkin lymphoma.

Relapsed or refractory (rel/ref) classical Hodgkin lymphoma (cHL) remains a clinical challenge, with limited effective treatment options available after stem cell transplantation. In a multicenter phase 2 study, the efficacy of lenalidomide in rel/ref cHL patients was evaluated at a dose of 25 mg/d on days 1-21 of a 28-day cycle. Patients remained on lenalidomide until disease progression or an unacceptable adverse event (AE) occurred. Thirty-eight cHL patients were enrolled with a median of 4 (range, 2-9) prior therapies; 87% had undergone prior stem cell transplantation and 55% of patients did not respond to their last prior therapy. Of 36 evaluable patients, responses were 1 complete remission (CR), 6 partial remissions (PRs), and 5 patients with stable disease (SD) for ≥ 6 months resulting in an International Working Committee (IWC) objective overall response rate (ORR) of 19% and a cytostatic ORR of 33%. Decreased chemokine (CCL17 and CCL22) plasma levels at 2 weeks were associated with a subsequent response. The treatment was well tolerated, and the most common grade 3/4 AEs were neutropenia (47%), anemia (29%), and thrombocytopenia (18%). Four patients discontinued lenalidomide because of rash, elevated transaminases/bilirubin, and cytopenias. We provide preliminary evidence of lenalidomide's activity in patients with rel/ref cHL, and therefore exploration of lenalidomide in combination with other active agents is warranted. This trial is registered at www.ClinicalTrials.gov as NCT00540007.

A validation study of new cryopreservation bags for implementation in a blood and marrow transplant laboratory.

BACKGROUND: A new cryopreservation bag for hematopoietic cell transplantation requires validation as a safe alternative to the bag currently being used in the laboratory. STUDY DESIGN AND METHODS: The new bag was validated using both laboratory and clinical criteria. Laboratory validation proceeded using paired samples of mononuclear cells processed using standard procedures. Cells cryopreserved in the new and old bags were compared for viability, cell counts, CD34 enumeration, colony-forming unit assays, and bag integrity. After completion of laboratory investigations, engraftment with the new bags was followed and compared to historical engraftment using the old bags. RESULTS: There were no significant differences between the old and new bags detected using laboratory studies. Bag integrity was equivalent. The validation data suggested impaired cell function after cryopreservation in the new bags, but there were no significant differences in engraftment potential using either material. Days to engraftment was longer using the new bags, but statistical analysis revealed an association with CD34 dose and not with cryopreservation bag type. CONCLUSION: The new bags were noninferior to the old bags. A change in cryopreservation bag type may appear to affect cell function and potentially affect engraftment. Multiple analyses may be needed to understand the effect of cell processing changes.

A phase III study of anti-B4-blocked ricin as adjuvant therapy post-autologous bone marrow transplant: CALGB 9254.

Anti-B4-blocked ricin (anti-B4-bR) is a potent immunotoxin directed against the CD19 antigen. Previous phase I and II studies suggested a possible role for anti-B4-bR as consolidation after high-dose chemotherapy and autologous stem cell transplant. Cancer and Leukemia Group B (CALGB) 9254 is a phase III study which randomized 157 patients with B-cell lymphoma in complete remission following autologous transplant to treatment with anti-B4-bR or observation. With a median follow-up time for patients of 5.8 years, the median event-free survival for protocol treatment and observation are 2.1 and 2.9 years, respectively (p = 0.275). The median overall survival for treatment and observation are 6.1 years and not reached, respectively (p = 0.063). Therefore, no differences were found in event-free survival and overall survival between protocol treatment and observation, although there was a trend toward improved survival with observation. These data fail to support a role for anti-B4-bR as consolidative therapy after bone marrow transplant in patients with B-cell lymphoma.

Possible role of engraftment syndrome and autologous graft-versus-host disease in myelodysplastic syndrome after autologous stem cell transplantations: retrospective analysis and review of the literature.

BACKGROUND: We report a retrospective study of 452 patients with lymphoma from 1991 to 2006, with 274 men and 178 women, median age of 50 years (range, 16-76 years). PATIENTS AND METHODS: There were 85 patients with Hodgkin lymphoma (HL) and 367 with non-Hodgkin lymphoma (NHL). Eleven patients received a second autologous transplantation for progressive lymphoma, and another 4 received a second allogeneic transplantation for myelodysplastic syndrome (MDS). Twenty-seven patients had skin biopsies, and 2 patients had gastrointestinal biopsies consistent with graft-versus-host disease (GVHD), and 11 patients developed severe engraftment syndrome (ES), as defined by noninfectious fever and skin rash with or without pulmonary infiltrates requiring systemic steroids. RESULTS: The median follow-up of the patients was 6.2 years, and median overall survival was 5.3 years. Twenty-four patients (5.3%) developed MDS with median time of onset of 4.2 years (range, 8 months to 7.5 years). An additional 5 patients developed clonal karyotypic abnormalities in the bone marrow without clinical MDS. Actuarial probabilities of developing MDS at 5 and 8 years after transplantation were 5% and 15%, respectively. CONCLUSION: The incidences of MDS are similar in HL and NHL. Multivariate analysis revealed older age, occurrence of ES/GVHD, and longer intervals between the initial diagnoses to transplantation as independent factors. It is conceivable that perturbation to the host immunity caused by either previous chemotherapy or conditioning regimens in the elderly might play a role in the development of MDS after autologous transplantation.

Impact of high-dose chemotherapy on the ability to deliver subsequent local-regional radiotherapy for breast cancer: analysis of Cancer and Leukemia Group B Protocol 9082.

PURPOSE: To report, from Cancer and Leukemia Group B Protocol 9082, the impact of high-dose cyclophosphamide, cisplatin, and BCNU (HD-CPB) vs. intermediate-dose CPB (ID-CPB) on the ability to start and complete the planned course of local-regional radiotherapy (RT) for women with breast cancer involving >or=10 axillary nodes. METHODS AND MATERIALS: From 1991 to 1998, 785 patients were randomized. The HD-CPB and ID-CPB arms were balanced regarding patient characteristics. The HD-CPB and ID-CPB arms were compared on the probability of RT initiation, interruption, modification, or incompleteness. The impact of clinical variables and interactions between variables were also assessed. RESULTS: Radiotherapy was initiated in 82% (325 of 394) of HD-CPB vs. 92% (360 of 391) of ID-CPB patients (p = 0.001). On multivariate analyses, RT was less likely given to patients who were randomized to HD treatment (odds ratio [OR] = 0 .38, p < 0.001), older (p = 0.005), African American (p = 0.003), postmastectomy (p = 0.02), or estrogen receptor positive (p = 0.03). High-dose treatment had a higher rate of RT interruption (21% vs. 12%, p = 0.001, OR = 2.05), modification (29% vs. 14%, p = 0.001, OR = 2.46), and early termination of RT (9% vs. 2%, p = 0.0001, OR = 5.35), compared with ID. CONCLUSION: Treatment arm significantly related to initiation, interruption, modification, and early termination of RT. Patients randomized to HD-CPB were less likely to initiate RT, and of those who did, they were more likely to have RT interrupted, modified, and terminated earlier than those randomized to ID-CPB. The observed lower incidence of RT usage in African Americans vs. non-African Americans warrants further study.

Music for patients with hematological malignancies undergoing bone marrow biopsy: a randomized controlled study of anxiety, perceived pain, and patient satisfaction.

OBJECTIVE: To examine the impact of random assignment to music versus usual care on anxiety, perceived pain level and patient satisfaction in patients undergoing bone marrow biopsies. METHOD: Patients were randomized to music or usual care after completing a baseline questionnaire. All patients completed a post-procedure questionnaire. RESULTS: Study participants (N=59) had a mean age of 50.9 years (SD = 13.9; range 22-78). Post-procedure state anxiety (STAI) and pain rating (VAS) were not significantly different between groups (STAI p=0.766; VAS p=0.771). However, patient satisfaction with music was high; 66% of these patients said they very much preferred to listen to music at a future biopsy. CONCLUSIONS: While there were no significant group differences for the music intervention compared to standard of care for anxiety or perceived pain, additional feedback indicated that patients found the music intervention beneficial and requested use of music during future procedures.

Immunochemotherapy and autologous stem-cell transplantation for untreated patients with mantle-cell lymphoma: CALGB 59909.

PURPOSE Mantle-cell lymphoma (MCL) is an aggressive B-cell non-Hodgkin's lymphoma with a poor prognosis. We explored the feasibility, safety, and effectiveness of an aggressive immunochemotherapy treatment program that included autologous stem-cell transplantation (ASCT) for patients up to age 69 years with newly diagnosed MCL. PATIENTS AND METHODS The primary end point was 2-year progression-free survival (PFS). A successful trial would yield a 2-year PFS of at least 50% and an event rate (early progression plus nonrelapse mortality) less than 20% at day +100 following ASCT. Seventy-eight patients were treated with two or three cycles of rituximab combined with methotrexate and augmented CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone). This treatment was followed by intensification with high doses of cytarabine and etoposide combined with rituximab and filgrastim to mobilize autologous peripheral-blood stem cells. Patients then received high doses of carmustine, etoposide, and cyclophosphamide followed by ASCT and two doses of rituximab. Results There were two nonrelapse mortalities, neither during ASCT. With a median follow-up of 4.7 years, the 2-year PFS was 76% (95% CI, 64% to 85%), and the 5-year PFS was 56% (95% CI, 43% to 68%). The 5-year overall survival was 64% (95% CI, 50% to 75%). The event rate by day +100 of ASCT was 5.1%. CONCLUSION The Cancer and Leukemia Group B 59909 regimen is feasible, safe, and effective in patients with newly diagnosed MCL. The incorporation of rituximab with aggressive chemotherapy and ASCT may be responsible for the encouraging outcomes demonstrated in this study, which produced results comparable to similar treatment regimens.

A prospective, randomized, double-blind controlled trial of acetaminophen and diphenhydramine pretransfusion medication versus placebo for the prevention of transfusion reactions.

BACKGROUND: Acetaminophen and diphenhydramine are commonly used as pretransfusion medications to prevent transfusion reactions. The purpose of this study was to prospectively compare the risk of transfusion reactions in hematology/oncology patients who receive acetaminophen with diphenhydramine or placebo before transfusion. STUDY DESIGN AND METHODS: A randomized, double-blind, placebo-controlled transfusion reaction study of 315 eligible patients was performed. Inclusion criteria were patients aged 18 to 65 years admitted to the leukemia or bone marrow transplant (BMT) services. Patients were excluded if they had a known allergy to either acetaminophen or diphenhydramine or had a documented history of a febrile or allergic transfusion reaction. All blood products were administered using a leukofilter. Study medications were given 30 minutes before transfusions and no other acetaminophen or diphenhydramine was given within 4 hours of administration of the study medications. Patients were monitored for the development of reaction symptoms within 4 hours after the transfusion. RESULTS: A total of 154 active drug patients were compared to 161 placebo patients. There was no significant difference in the overall risk of transfusion reactions between the two groups. However, analysis of specific reaction types revealed a significant decrease in the risk of febrile reactions when pretransfusion medication is used in addition to bedside leukoreduction. CONCLUSIONS: Pretransfusion medication of leukemia or BMT patients without a history of transfusion reaction does not decrease the overall risk of transfusion reactions. However, pretransfusion medication may decrease the risk of febrile nonhemolytic transfusion reactions to leukoreduced blood products.

Feasibility of administering oblimersen (G3139; Genasense) with imatinib mesylate in patients with imatinib resistant chronic myeloid leukemia--Cancer and leukemia group B study 10107.

The CALGB studied the feasibility and effectiveness of adding oblimersen (G3139; Genasense) to imatinib mesylate (IM) in imatinib-resistant chronic phase chronic myeloid leukemia (CML) patients. We hypothesised that IM resistant CML cells are no longer being driven to proliferate by Bcr/Abl activity alone. Instead, the anti-apoptotic protein Bcl-2 would regulate one of the pathways controlling growth and/or viability. Thus, blocking both Bcr/Abl and Bcl-2 simultaneously would result in hematologic and cytogenetic improvement. Oblimersen was administered via continuous intravenous infusion over 10 days every 21 days, along with daily IM. Doses of both drugs were escalated in 3 cohorts; the initial dose of IM was 600 mg/day. Response was defined as a decrease by >30% in the percentage of t(9;22) metaphase cells. Twelve patients had primary and nine had secondary imatinib resistance. Ten patients received 4 mg/kg/day oblimersen/600 mg IM, six patients received 7 mg/kg/day oblimersen/600 mg IM and five patients received 7 mg/kg/day oblimersen/800 mg IM. Only two (9.5%) patients achieved a decrease by >30% in the percentage of t(9;22) metaphase cells. Although the combination of oblimersen and IM is safe and feasible, we did not observe clinical benefit in these patients with imatinib-resistant CML using these doses and schedule.
