Background and Methods It is uncertain whether mortality rates among patients who have undergone bone marrow transplantation return to the level of the mortality rates of the general population. We analyzed the characteristics of 6691 patients listed in the International Bone Marrow Transplant Registry. All the patients were free of their original disease two years after allogeneic bone marrow transplantation. Mortality rates in this cohort were compared with those of an age-, sex-, and nationality-matched general population. Cox proportional-hazards regression was used to identify risk factors for death more than two years after transplantation (late death). Results Among patients who were free of disease two years after transplantation, the probability of living for five more years was 89 percent (95 percent confidence interval, 88 to 90 percent). Among patients who underwent transplantation for aplastic anemia, the risk of death by the sixth year after transplantation did not differ significantly from ...

BACKGROUND A complete remission is essential for prolonging survival in patients with acute myeloid leukemia (AML). Daunorubicin is a cornerstone of the induction regimen, but the optimal dose is unknown. In older patients, it is usual to give daunorubicin at a dose of 45 to 50 mg per square meter of body-surface area. METHODS Patients in whom AML or high-risk refractory anemia had been newly diagnosed and who were 60 to 83 years of age (median, 67) were randomly assigned to receive cytarabine, at a dose of 200 mg per square meter by continuous infusion for 7 days, plus daunorubicin for 3 days, either at the conventional dose of 45 mg per square meter (411 patients) or at an escalated dose of 90 mg per square meter (402 patients); this treatment was followed by a second cycle of cytarabine at a dose of 1000 mg per square meter every 12 hours [DOSAGE ERROR CORRECTED] for 6 days. The primary end point was event-free survival. RESULTS The complete remission rates were 64% in the group that received the escalated dose of daunorubicin and 54% in the group that received the conventional dose (P=0.002); the rates of remission after the first cycle of induction treatment were 52% and 35%, respectively (P<0.001). There was no significant difference between the two groups in the incidence of hematologic toxic effects, 30-day mortality (11% and 12% in the two groups, respectively), or the incidence of moderate, severe, or life-threatening adverse events (P=0.08). Survival end points in the two groups did not differ significantly overall, but patients in the escalated-treatment group who were 60 to 65 years of age, as compared with the patients in the same age group who received the conventional dose, had higher rates of complete remission (73% vs. 51%), event-free survival (29% vs. 14%), and overall survival (38% vs. 23%). CONCLUSIONS In patients with AML who are older than 60 years of age, escalation of the dose of daunorubicin to twice the conventional dose, with the entire dose administered in the first induction cycle, effects a more rapid response and a higher response rate than does the conventional dose, without additional toxic effects.

BACKGROUND High-dose chemoradiotherapy combined with autologous bone marrow transplantation can cure patients with disseminated, aggressive non-Hodgkins lymphoma in whom first-line chemotherapy has failed. In contrast, cure is rare with second-line chemotherapy. It has been suggested that patients with slow responses to the initial phase of first-line chemotherapy are at high risk for relapse. Therefore, such patients are potential candidates for early bone marrow transplantation. METHODS To investigate whether patients with slow responses, defined as only a partial response after three courses of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP), would benefit from early transplantation, we conducted a prospective, randomized trial. The early application of high-dose chemoradiotherapy and autologous bone marrow transplantation was compared with the continuation of CHOP therapy for another five courses. Patients with complete responses after three courses of CHOP (fast responses) and patients who responded partially but still had tumor-positive marrow continued with another five courses of CHOP. The study end points were the response rate, overall survival, disease-free survival, and event-free survival. RESULTS Of 286 patients who could be evaluated for the rapidity of their response after three courses of CHOP, 38 percent had fast responses, 47 percent had slow responses, and 15 percent had no response. Among 106 patients with slow responses who had lymphoma-negative marrow, 69 patients (65 percent) were randomized. Seventy-four percent of the CHOP group and 68 percent of the transplantation group had complete remissions (P = 0.54). At four years the rates of overall, disease-free, and event-free survival were 85, 72, and 53 percent, respectively, in the CHOP group and 56, 60, and 41 percent in the transplantation group (P > 0.10). The disease-free survival in both groups did not differ significantly from that of nonrandomized patients with fast responses (54 percent at four years). CONCLUSIONS The early application of high-dose, marrow-ablative chemoradiotherapy with autologous bone marrow transplantation does not improve the outcome in patients with aggressive non-Hodgkins lymphoma that responds slowly to first-line CHOP chemotherapy.

PURPOSE AND METHODS A prospective, randomized, multicenter phase III trial was performed to investigate the feasibility of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) chemotherapy in elderly patients ( > or = 60 years) with advanced non-Hodgkins lymphoma (NHL) of intermediate- and high-grade malignancy, and to compare the tolerance and efficacy of doxorubicin versus mitoxantrone (CHOP v CNOP). RESULTS Of 157 enrolled patients, 148 were eligible and 145 were assessable for response. Thirty-one percent of CNOP and 45% of CHOP patients completed six cycles without dose reduction. The cumulative normalized dose-intensity (NDI) was 92% with CHOP and 90% with CNOP after six cycles. The overall complete response (CR) rates were 49% and 31% in CHOP- and CNOP-treated patients, respectively (P = .03). Survival with CNOP was significantly worse as compared with CHOP (P = .03). Lymphoma-specific survival was significantly better in CHOP-treated patients (P = .034) At 3 years, 42% of CHOP and 26% of CNOP patients were alive. Additional unfavorable prognostic factors at diagnosis were high serum lactate dehydrogenase (LDH) level, bulky mass, and low performance status, but not age. The median disease-free intervals of complete responders were 27 (CHOP) and 15 (CNOP) months, respectively. Considering the complete group of patients, at 3 years 17% of CHOP and 13% of CNOP patients were alive and disease-free (P = .12). Common toxicity criteria (CTC) grade > or = 2 with CNOP and CHOP was not different. CONCLUSION CHOP is well tolerated in elderly patients with advanced intermediate- or high-grade NHL and its NDI is not seriously impaired. Treatment with CHOP (doxorubicin) results in better CR and survival rates than CNOP (mitoxantrone). CHOP should be recommended for elderly patients with high-risk NHL.

Abstract At present, no definite conclusions can be drawn about the real extent of the pain suffered by cancer patients. A population‐based study was conducted to obtain reliable information about the prevalence and severity of pain in cancer patients (all phases) and about predictors of pain. A representative sample of cancer patients was recruited in the area from a cancer registry. Pain was assessed by the Brief Pain Inventory (BPI). Adequacy of pain treatment was assessed with the Pain Management Index (PMI). We found that 55% of the 1429 respondents had experienced pain past week; in 44% (n = 351), the pain was moderate to severe (BPI score ⩾4). Total prevalence of pain/moderate to severe pain was present in 49%/41% in patients with curative treatment ⩾6 months ago, 57%/43% in patients with current curative treatment or treatment <6 months ago, 56%/43% in patients with current palliative anti‐cancer treatment and in 75%/70% in patients for whom treatment was no longer feasible. Positive predictors of the prevalence of pain were lower education level, more advanced disease and haematological (excluding (non)‐Hodgkin lymphoma), gastro‐intestinal, lung, or breast malignancies. According to the PMI, analgesic treatment was inadequate in 42% of the patients. Negative predictors of adequate treatment were current curative anti‐cancer treatment and low education level. Conclusion: A substantial proportion of cancer patients does suffer from moderate to severe pain and does not receive adequate pain treatment.

PURPOSE Myeloproliferative neoplasm (MPN) symptoms are troublesome to patients, and alleviation of this burden represents a paramount treatment objective in the development of MPN-directed therapies. We aimed to assess the utility of an abbreviated symptom score for the most pertinent and representative MPN symptoms for subsequent serial use in assessing response to therapy. PATIENTS AND METHODS The Myeloproliferative Neoplasm Symptom Assessment Form total symptom score (MPN-SAF TSS) was calculated as the mean score for 10 items from two previously validated scoring systems. Questions focus on fatigue, concentration, early satiety, inactivity, night sweats, itching, bone pain, abdominal discomfort, weight loss, and fevers. RESULTS MPN-SAF TSS was calculable for 1,408 of 1,433 patients with MPNs who had a mean score of 21.2 (standard deviation [SD], 16.3). MPN-SAF TSS results significantly differed among MPN disease subtypes (P<.001), with a mean of 18.7 (SD, 15.3), 21.8 (SD, 16.3), and 25.3 (SD, 17.2) for patients with essential thrombocythemia, polycythemia vera, and myelofibrosis, respectively. The MPN-SAF TSS strongly correlated with overall quality of life (QOL; r=0.59; P<.001) and European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) functional scales (all P<.001 and absolute r≥0.50 except social functioning r=0.48). No significant trends were present when comparing therapy subgroups. The MPN-SAF TSS had excellent internal consistency (Cronbachs α=.83). Factor analysis identified a single underlying construct, indicating that the MPN-SAF TSS is an appropriate, unified scoring method. CONCLUSION The MPN-SAF TSS is a concise, valid, and accurate assessment of MPN symptom burden with demonstrated clinical utility in the largest prospective MPN symptom study to date. This new prospective scoring method may be used to assess MPN symptom burden in both clinical practice and trial settings.

Myelofibrosis is a myeloproliferative disorder incurable with conventional strategies. Several small series have reported long-term disease-free survival (DSF) after allogeneic hematopoietic cell transplantation (HCT). In this study, we analyze the outcomes of 289 patients receiving allogeneic transplantation for primary myelofibrosis between 1989 and 2002, from the database of the Center for International Bone Marrow Transplant Research (CIBMTR). The median age was 47 years (range: 18-73 years). Donors were HLA identical siblings in 162 patients, unrelated individuals in 101 patients, and HLA nonidentical family members in 26 patients. Patients were treated with a variety of conditioning regimens and graft-versus-host disease (GVHD) prophylaxis regimens. Splenectomy was performed in 65 patients prior to transplantation. The 100-day treatment-related mortality was 18% for HLA identical sibling transplants, 35% for unrelated transplants, and 19% for transplants from alternative related donors. Corresponding 5-year overall survival (OS) rates were 37%, 30%, and 40%, respectively. DFS rates were 33%, 27%, and 22%, respectively. DFS for patients receiving reduced-intensity transplants was comparable: 39% for HLA identical sibling donors and 17% for unrelated donors at 3 years. In this large retrospective series, allogeneic transplantation for myelofibrosis resulted in long-term relapse-free survival (RFS) in about one-third of patients.

Do some patients benefit from an unrelated donor (URD) transplant because of a stronger graft-versus-leukemia (GVL) effect? We analyzed 4099 patients with acute myeloid leukemia (AML), acute lymphoblastic leukemia (ALL), and chronic myeloid leukemia (CML) undergoing a myeloablative allogeneic hematopoietic cell transplantation (HCT) from an URD (8/8 human leukocyte antigen [HLA]-matched, n=941) or HLA-identical sibling donor (n=3158) between 1995 and 2004 reported to the CIBMTR. In the Cox regression model, acute and chronic GVHD were added as time-dependent variables. In multivariate analysis, URD transplant recipients had a higher risk for transplantation-related mortality (TRM; relative risk [RR], 2.76; P< .001) and relapse (RR, 1.50; P< .002) in patients with AML, but not ALL or CML. Chronic GVHD was associated with a lower relapse risk in all diagnoses. Leukemia-free survival (LFS) was decreased in patients with AML without acute GVHD receiving a URD transplant (RR, 2.02; P< .001) but was comparable to those receiving HLA-identical sibling transplants in patients with ALL and CML. In patients without GVHD, multivariate analysis showed similar risk of relapse but decreased LFS for URD transplants for all 3 diagnoses. In conclusion, risk of relapse was the same (ALL, CML) or worse (AML) in URD transplant recipients compared with HLA-identical sibling transplant recipients, suggesting a similar GVL effect.

Reduced-intensity conditioning (RIC) regimens have been increasingly used for allogeneic hematopoietic stem cell transplantation (HSCT) in follicular lymphoma (FL). We compared traditional myeloablative conditioning regimens to RIC in FL. Outcomes of HLA-identical sibling HSCT for FL in 208 recipients reported to the Center for International Blood and Marrow Transplant Research (CIBMTR) between 1997 and 2002 were studied. Conditioning regimens were categorized as myeloablative (N = 120) or RIC (N = 88). Use of RIC regimens increased from <10% of transplants in 1997 to >80% in 2002 signaling a major shift in practice. Patients receiving RIC were older and had a longer interval from diagnosis to transplant. These differences did not correlate with outcomes. Median follow-up of survivors was 50 months (4-96 months) after myeloablative conditioning versus 35 months (4-82 months) after RIC (P < .001). At 3 years, overall survival (OS) for the myeloablative and RIC cohorts were 71 (63%-79%) and 62 (51%-72%; P = .15) and progression free survival (PFS), 67 (58%-75%) and 55 (44%-65%; P = .07), respectively. Lower Karnofsky performance score (KPS) and resistance to chemotherapy were associated with higher treatment-related mortality (TRM) and lower OS and PFS. On multivariate analysis, an increased risk of lymphoma progression after RIC was observed (relative risk = 2.97, P = .04). RIC has become the de facto standard in allogeneic HSCT for FL, and appears to result in similar long-term outcomes. Although disease-free survival (DPS) is similar compared to myeloablative conditioning, an increased risk of late disease progression after RIC is concerning.

PURPOSE The Prospective Oral Mucositis Audit assessed the incidence, duration, and determinants of severe oral mucositis (OM; WHO oral toxicity scale grades 3 to 4) in patients with multiple myeloma (MM) or non-Hodgkins lymphoma (NHL) receiving high-dose conditioning chemotherapy before autologous stem-cell transplantation. PATIENTS AND METHODS Patients with MM (n = 109; mean age, 57 +/- 8 years) or NHL (n = 88; mean age, 50 +/- 13 years) were treated with high-dose melphalan (200 mg/m(2)) or carmustine 300 mg/m(2), etoposide 800 mg/m(2), cytarabine 800 to 1,600 mg/m(2), and melphalan 140 mg/m(2) chemotherapy, respectively, in 25 European centers. OM assessments were made daily until 30 days after transplantation or hospital discharge. High quality of OM assessment was ensured by an intensive training program. RESULTS Severe OM occurred in 46% (95% CI, 36% to 56%) of patients with MM and 42% (95% CI, 32% to 53%) of patients with NHL, with a mean duration of 5.3 days (95% CI, 4.4 to 6.1 days) and 5.5 days (95% CI, 4.5 to 6.7 days), respectively. Time from start of conditioning to peak OM score was 12.1 +/- 2.6 and 14.6 +/- 2.4 days. Severe OM risk and/or duration was significantly associated with higher chemotherapy dose per kilogram of body weight and poor performance status, but in contrast with some previous reports, this was not related to age. CONCLUSION Severe OM is more common in the transplantation setting than previously reported, justifying effective preventative and therapeutic measures.
