Overall survival of myelodysplastic syndrome patients after azacitidine discontinuation and applicability of the North American MDS Consortium scoring system in clinical practice.

BACKGROUND: Azacitidine (AZA) is the standard treatment for myelodysplastic syndromes (MDS); however, many patients prematurely stop therapy and have a dismal outcome. METHODS: The authors analyzed outcomes after AZA treatment for 402 MDS patients consecutively enrolled in the Italian MDS Registry of the Fondazione Italiana Sindromi Mielodisplastiche, and they evaluated the North American MDS Consortium scoring system in a clinical practice setting. RESULTS: At treatment discontinuation, 20.3% of the patients were still responding to AZA, 35.4% of the cases had primary resistance, and 44.3% developed adaptive resistance. Overall survival (OS) was better for patients who discontinued treatment while in response because of planned allogeneic hematopoietic stem cell transplantation (HSCT; median OS, not reached) in comparison with patients with primary resistance (median OS, 4 months) or adaptive resistance (median OS, 5 months) or patients responsive but noncompliant/intolerant to AZA (median OS, 4 months; P = .004). After AZA discontinuation, 309 patients (77%) received best supportive care (BSC), 60 (15%) received active treatments, and 33 (8%) received HSCT. HSCT was associated with a significant survival advantage, regardless of the response to AZA. The North American MDS Consortium scoring system was evaluable in 278 of the 402 cases: patients at high risk had worse OS than patients at low risk (3 and 7 months, respectively; P < .001). The score was predictive of survival both in patients receiving BSC (median OS, 2 months for high-risk patients vs 5 months for low-risk patients) and in patients being actively treated (median OS, 8 months for high-risk patients vs 16 months for low-risk patients; P < .001), including transplant patients. CONCLUSIONS: Real-life data confirm that this prognostic scoring system for MDS patients failing a hypomethylating agent seems to be a useful tool for optimal prognostic stratification and for choosing a second-line treatment after AZA discontinuation.

A Comparison of the Conditioning Regimens BEAM and FEAM for Autologous Hematopoietic Stem Cell Transplantation in Lymphoma: An Observational Study on 1038 Patients From Fondazione Italiana Linfomi.

BEAM (carmustine [bis-chloroethylnitrosourea (BCNU)]-etoposide-cytarabine-melphalan) chemotherapy is the standard conditioning regimen for autologous stem cell transplantation (ASCT) in lymphomas. Owing to BCNU shortages, many centers switched to fotemustine-substituted BEAM (FEAM), lacking proof of equivalence. We conducted a retrospective cohort study in 18 Italian centers to compare the safety and efficacy of BEAM and FEAM regimens for ASCT in lymphomas performed from 2008 to 2015. We enrolled 1038 patients (BEAM = 607, FEAM = 431), of which 27% had Hodgkin lymphoma (HL), 14% indolent non-Hodgkin lymphoma (NHL), and 59% aggressive NHL. Baseline characteristics including age, sex, stage, B-symptoms, extranodal involvement, previous treatments, response before ASCT, and overall conditioning intensity were well balanced between BEAM and FEAM; notable exceptions were median ASCT year (BEAM = 2011 versus FEAM = 2013, P < .001), Sorror score ≥3 (BEAM = 15% versus FEAM = 10%, P = .017), and radiotherapy use (BEAM = 18% versus FEAM = 10%, P < .001). FEAM conditioning resulted in higher rates of gastrointestinal and infectious toxicities, including severe oral mucositis grade ≥3 (BEAM = 31% versus FEAM = 44%, P < .001), and sepsis from Gram-negative bacteria (mean isolates/patient: BEAM = .1 versus FEAM = .19, P < .001). Response status at day 100 post-ASCT (overall response: BEAM = 91% versus FEAM = 88%, P = .42), 2-year overall survival (83.9%; 95% confidence interval [CI], 81.5% to 86.1%) and progression-free survival (70.3%; 95% CI, 67.4% to 73.1%) were not different in the two groups. Mortality from infection was higher in the FEAM group (subhazard ratio, 1.99; 95% CI, 1.02 to 3.88; P = .04). BEAM and FEAM do not appear different in terms of survival and disease control. However, due to concerns of higher toxicity, fotemustine substitution in BEAM does not seem justified, if not for easier supply.

Prognostic role of immunohistochemical analysis of 5 mc in myelodysplastic syndromes.

BACKGROUND: Aberrant DNA methylation at CpG islands within promoters is increasingly recognised as a common event in human cancers and has been associated with the silencing of important tumour suppressor genes. Epigenetic therapy using hypomethylating agents has demonstrated clinical effectiveness; the drugs azacitidine and decitabine have been approved for the treatment of MDS. METHOD: We investigated the association between global DNA methylation and clinical outcome in MDS. We evaluated 134 MDS bone marrow trephine biopsies (BMTB) by immunohistochemistry and compared the results with those from an age-matched group of normal BMTB. Immunohistochemistry was performed on paraffin-embedded sections using the anti-5-methylcytosine (5mc) antibody. RESULTS: Our results showed that the 5mc immunostaining score (M-score) of patients with MDS was higher than those of normal controls and that overall survival significantly correlated with global DNA methylation, age and IPSS score. Therefore, we found that patients with high levels of methylation had a shorter median overall survival (OS) compared with patients with lower levels. These immunohistochemistry results were confirmed by analysing global DNA methylation on LINE-1 sequences using the COBRA method and pyrosequencing. CONCLUSION: This study reports that global DNA methylation detected by immunohistochemistry predicts OS in MDS.

ThaDD plus high dose therapy and autologous stem cell transplantation does not appear superior to ThaDD plus maintenance in elderly patients with de novo multiple myeloma.

OBJECTIVES: With the aim to address the issue whether high-dose therapy (HDT) is required after new drugs combinations to improve outcome of elderly newly diagnosed multiple myeloma (MM) patients, we compared the toxicity and the outcome of ThaDD plus maintenance to those of ThaDD plus HDT-autologous stem cell transplantation (ASCT). METHODS: Sixty-two patients not eligible for HDT receiving six courses of ThaDD regimen plus maintenance with thalidomide were compared to 26 patients eligible for HDT treated with four courses of ThaDD followed by melphalan 100-200 mg/m(2) and ASCT. The two groups were matched for the main characteristics except for age favouring the HDT group. RESULTS AND CONCLUSIONS: Complete remission (CR) obtained with ThaDD plus maintenance was 24% whereas it was 57% after ThaDD plus HDT-ASCT (P = 0.0232). However, after a median follow-up of 36 months, median time to progression (TTP) and progression free survival (PFS) of the group of patients undergone HDT were not significantly different to those of patients receiving ThaDD plus maintenance (32 vs. 31 months: P = 0.962; 32 vs. 29 months: P = 0.726, respectively). Five-year overall survival (OS) was 49% in the first group and 46% in the latter one (P = 0.404). As expected, a significantly higher incidence of grade 3-4 neutropenia, thrombocytopenia, infections, mucositis and alopecia were observed in the ThaDD plus HDT group. Our results suggest that in elderly MM patients ThaDD plus HDT, albeit significantly increases CR rate, seems to be equivalent to ThaDD plus maintenance in terms of TTP, PFS and OS. These results challenge the requirement for HDT consolidation in this subset of patients.

Thalidomide-dexamethasone versus interferon-alpha-dexamethasone as maintenance treatment after ThaDD induction for multiple myeloma: a prospective, multicentre, randomised study.

Maintenance therapy was explored in multiple myeloma (MM) patients after conventional thalidomide, dexamethasone and pegylated liposomal doxorubicin (ThaDD). Patients with newly or relapsed MM obtaining at least minor response after 6 ThaDD courses, were randomised to receive alpha-interferon (IFN) 3 MU 3 times a week or thalidomide 100 mg daily until relapse. Both groups also received pulsed dexamethasone 20 mg 4 d a month. Fifty-one patients were randomized in the IFN-dexamethasone (ID) arm and 52 in the thalidomide-dexamethasone (TD) arm. The characteristics of two groups were similar. A significantly better 2-years progression-free survival (PFS; 63% vs. 32%; P = 0.024) and overall survival (84% vs. 68%; P = 0.030) was observed in the thalidomide arm. In high-risk patients and in those achieving less than very good partial response after induction, TD fared better in term of PFS. Main side effects were peripheral neuropathy and constipation in TD group, fatigue, anorexia and haematological toxicity in ID arm. There was a 21% probability of discontinuation at 3 years in the thalidomide arm and 44% in the IFN arm (P = 0.014). Low-dose thalidomide plus pulsed low-dose dexamethasone after conventional thalidomide combination-based therapy was also feasible in the long term, enabling significantly better residual disease control if compared with a standard maintenance therapy.

Bleomycin, vinblastine and dacarbazine combined with nonpegylated liposomal doxorubicin (MBVD) in elderly (≥70 years) or cardiopathic patients with Hodgkin lymphoma: a phase-II study from Fondazione Italiana Linfomi (FIL).

This phase-II study assessed activity and toxicity of substituting conventional doxorubicin with nonpegylated liposomal doxorubicin in the conventional ABVD regimen for the treatment of elderly or cardiopathic patients with HL. Stage I-IIA and IIB-IV patients were treated with three courses of MBVD plus radiotherapy, or six courses of MBVD, respectively, plus radiotherapy limited to bulky or residual disease areas. The primary endpoints were CR rate and the rate of cardiac events. Forty-seven patients were enrolled. Median age was 75 years, 13 had stage I-II disease. Overall, CR was achieved by 36 patients (77%, 95% CI: 62-88), 100% and 68% in stage I-II and III-IV, respectively. With a median follow-up of 40 months (IQR: 36-45). Three-year overall survival (OS) and progression-free survival (PFS) were 70% and 43%, respectively. Cardiac events grades 3-5 were reported in two patients. In conclusion, MBVD's activity and safety profile was comparable to historical ABVD data.

Serum C-reactive protein at diagnosis and response to therapy is the most powerful factor predicting outcome of multiple myeloma treated with thalidomide/ anthracycline-based therapy.

BACKGROUND: Few studies have focused on factors affecting outcome in patients with multiple myeloma (MM) treated with thalidomide-based therapy. We investigated factors affecting response, progression-free survival (PFS), and overall survival (OS) in patients with MM treated with the thalidomide, dexamethasone, and pegylated liposomal doxorubicin (ThaDD) regimen with the aim to select patients benefiting more from this therapy. PATIENTS AND METHODS: Sixty-six patients with MM were treated first line with the ThaDD regimen. We analyzed demographics and disease-related characteristics to search for factors affecting response (> or = very good partial remission [VGPR] vs. < VGPR], PFS, and OS. RESULTS: Overall, 45 patients (68%) showed response > or = VGPR; median TTP and OS were 23.5 months and 35.5 months, respectively. Multivariate analysis selected only serum C-reactive protein (sCRP) as a predictive factor for response (P < .0001). By multivariate analysis, normal sCRP level (P = .001) and response to treatment > or = VGPR (P = .007) were found to be associated with longer PFS. The factors that remained significantly associated with a longer OS when assessed by multivariate analysis were normal sCRP level (P = .005) and response to therapy > or = VGPR (P = .019). CONCLUSION: Serum C-reactive protein before therapy and response after therapy are the only factors useful in identifying patients benefiting from anthracycline/thalidomide-based therapy.

Early mortality in myeloma patients treated with first-generation novel agents thalidomide, lenalidomide, bortezomib at diagnosis: A pooled analysis.

INTRODUCTION: Early toxic death (≤60 days of diagnosis) in elderly multiple myeloma (MM) patients is attributable to active disease, age and co-morbidities. Rate of early toxic deaths is 10% with conventional chemotherapy mainly due to infection and renal failure. Novel agents have improved MM outcome at the expense of newer toxicity. METHODS: We analyzed 1146 individual patient data to assess toxic deaths during induction treatment with first-generation novel agents thalidomide, lenalidomide, bortezomib. RESULTS: During first-line therapy, 119/1146 patients (10%) died for any cause, and 47/1146 (4%) due to toxicity, including 12/1146 (1%) early deaths. The 24-month cumulative incidence was 4.1% without any difference between bortezomib (18/503 patients, 4%) and lenalidomide (29/643patients, 5%; p = 0.31). Toxic deaths occurred in 34/1039 (3%) patients <80 years and 13/107 (12%) patients ≥80 years. Causes were cardiac events (28%), infections (26%) and vascular complications (15%). In a multivariate analysis, older age and unfavorable ISS stage increased the risk of death. CONCLUSION: First-generation novel agents significantly reduced toxic deaths compared to conventional chemotherapy. One third of deaths during first-line therapy were due to cumulative drug-related toxicities, thus supportive approaches and prevention strategies should be optimized. The higher mortality rate for toxicity in octogenarians confirms the need for a careful frailty assessment.

The assessment of complexity in internal medicine patients. The FADOI Medicomplex Study.

BACKGROUND: Although the number of elderly people is progressively increasing in the world, old and very old patients have been under-represented and understudied in trials evaluating the efficacy of chronic illness management models. The usual hospital indicators and practice guidelines do not consider the effects of complexity - co-morbidity, social support, functional and cognitive status, patient adherence to therapy, risk of adverse drug reactions - in these subjects. The aim of this observational, multi-centric cohort study was to carefully assess factors contributing to the complexity of care for patients admitted to internal medicine wards. This was done by evaluating the severity of disease and degree of stability at admission, co-morbidity, age-related impairments, and the need for discharge planning plus post-discharge support. METHODS: A total of 386 patients from 11 internal medicine wards in Emilia-Romagna and Marche, Italy, enrolled in a given week were evaluated. At admission, the following variables were recorded: demographic characteristics, medical history, global clinical-social prognostic evaluation, co-morbidity, severity of illness, presence of shock or hemodynamic instability, coma, and frequencies and causes of unscheduled hospital re-admission. RESULTS: Cancer, congestive heart failure, pneumonia, stroke, and chronic obstructive pulmonary disease were the most frequent primary diagnoses. The complexity of our case study was characterized by several concomitant diseases. Over 50% of the patients were considered severe or more than severe, and over 20% extremely severe, with very high co-morbidity indices and illness severity scores. Some 55% of our patients were in need of partial or total care; 10% had some speech impairment, and 63% needed in-home health care after hospital discharge. CONCLUSIONS: The increasing numbers of elderly patients admitted to internal medicine departments suggests the need for a chronic illness management model, integrating gerontological and geriatric care to improve outcomes. For effective care, future protocols need to take a multi-dimensional, interdisciplinary approach to these patients and to develop a coordinated, integrated plan for treatment and long-term follow-up.

Low-dose thalidomide with pegylated liposomal doxorubicin and high-dose dexamethasone for relapsed/refractory multiple myeloma: a prospective, multicenter, phase II study.

The aim of this prospective, multicenter, phase II study was to investigate the combination of pegylated liposomal doxorubicin (Caelyx) 40 mg/m2 on day 1 every 28 days, dexamethasone 40 mg p.o. on days 1-4 and 9-12 and thalidomide 100 mg daily in 50 patients with advanced multiple myeloma. Twenty-six percent of patients achieved a complete response, 6% a near complete response, 6% a very good partial response, 38% a partial response, 16% a minor response and 8% progressed, for an overall response rate of 92%. The median event-free survival was 17 months and the median overall survival was not reached. Grade 3 non-hematologic toxicity occurred in 12% of patients, thromboembolic disease in 12% and severe infection in 16%. The combination of pegylated liposomal doxorubicin, dexamethasone an thalidomide is safe and very effective in advanced multiple myeloma.

Comparison of two regimens for the treatment of elderly patients with acute lymphoblastic leukaemia (ALL).

Acute lymphoblastic leukemia (ALL) represents a rare malignancy in the elderly and few authors have specifically focused on the treatment of ALL in this setting. We recently published the results of a prospective phase II study comprising an induction therapy with vincristine, Daunoxome and dexamethasone (VDXD) given to 15 patients aged 60 years. Here, we update the results after enrolling 17 patients, and we compare these with the results obtained in 17 elderly patients treated according to the GIMEMA ALL 0288 protocol. With the VDXD combination, elderly ALL had a higher CR rate (76.5%) than with the 0288 protocol (41%), and it was likely due to both lower induction mortality (17.5% vs. 35%) and a less resistant disease (6% vs. 24%). Infectious complications were more frequent with the VDXD combination whereas non-hematological side effects were comparable. Despite the similar DFS obtained with the two induction treatments, median EFS (3.9 months with 0288 vs. 12.8 with VDXD; p = 0.0486) and OS (4.5 vs. 21 months; p = 0.0239) were significantly higher with the VDXD regimen. In elderly ALL patients the administration of high-dose daunorubicin as a liposomal compound is feasible and seems able to improve CR rate, EFS and OS without increase in toxicity.

High-dose daunorubicin as liposomal compound (Daunoxome) in elderly patients with acute lymphoblastic leukemia.

Elderly acute lymphoblastic leukemia (ALL) is a rare condition associated with low complete remission (CR) rate and short survival. In order to improve these results, we evaluate the efficacy and toxicity of Daunoxome, a liposomal daunorubicin, exhibiting toxicity profile and pharmacokinetic indices better than standard daunorubicin. In total, 15 consecutive patients with nonmature ALL were enrolled on a prospective phase II study. No exclusion was made because of older age, poor performance status and organ dysfunctions. Median age was 69 years; performance status resulted >/=2 in nine patients (60%), six patients (40%) were bcr-abl positive and two-thirds of the patients had comorbidities. Induction therapy consisted of vincristine, Daunoxome and dexamethasone. Patients in CR received one or two consolidation cycles of cyclophosphamide, cytarabine and topotecan followed, in patients achieving CR, by a two-year rotating maintenance course including vincristine, Daunoxome, cyclophosphamide and prednisone. In all, 11 patients (73%) achieved CR, three patients (20%) died early during the induction phase and one patient (7%) had resistant disease. Five patients (33%) relapsed after 5-21 months. With a median follow-up of 20 months, disease free survival (DFS) and overall survival (OS) at 2 years were 36 and 38%, respectively. Major toxicity included myelosuppression and infection. Our experience demonstrates that a high dose of daunorubicin as liposomal compound can be safely administered in elderly ALL, exhibiting high antitumor activity. Our therapeutic program shows evidence of benefit in DFS and OS.

Assessment of vulnerability measures and their effect on survival in a real-life population of multiple myeloma patients registered at Marche Region Multiple Myeloma Registry.

UNLABELLED: Multiple myeloma (MM) therapy should be tailored according to patient characteristics although we do not know which ones to use. By studying the characteristics of 266 real-life patients, we found performance status (PS) and Charlson Comorbidity Index (CCI) as factors affecting survival of MM patients regardless of their disease characteristics. This study might help to select patients for tailoring therapy in clinical practice. BACKGROUND: Multiple myeloma is a typical disease of the elderly but how many and which patients can be considered 'vulnerable' and how this may affect patient outcome remain unsolved issues. PATIENTS AND METHODS: Data from 266 symptomatic MM patients registered at Marche MM registry from 2007 to 2010 were evaluated retrospectively. Vulnerability was defined as age > 75 years, PS (World Health Organization) ≥ 2, renal insufficiency (RI), bone fracture, cytopenias, and CCI score ≥ 1. Kaplan-Meier method and Cox regression were used to assess survival and associated factors. A vulnerability score (VS) incorporating significant vulnerability features was pursued to predict survival. RESULTS: Thirty-eight percent of patients were older than 75 years, 39% had PS = 2-4, 35% had at least 2 cytopenias, 40% had bone fracture, 14% RI, and 51% had CCI score ≥ 1. Cox regression selected international staging system (ISS) = III (hazard ratio [HR] = 1.6; P = .033), PS = 2-4 (HR = 2.5; P = .007), and CCI = 1-3 (HR = 2.1; P = .028) as factors associated with a worse overall survival. A VS including PS and CCI predicted median survival of 27 months in the 63 patients having a VS = 2 (both PS = 2-4 and CCI = 1-3) versus not reached (NR) in the 203 patients with VS = 0-1 (HR = 4.0; P < .0001). In younger patients multivariate analysis selected ISS = III (HR = 5.2; P = .006) and VS = 2 (HR = 5.5; P = .024) as factors associated with shorter survival whereas only VS = 2 (HR = 3.5; P = .002) affected worse survival in elderly. CONCLUSION: Such VS proved to be a powerful prognostic factor for survival of MM patients and it might be useful to identify true vulnerable patients regardless of age.

Infectious complications in patients with multiple myeloma treated with new drug combinations containing thalidomide.

The literature provides scant data concerning infectious complications and their effect on the outcome of patients with multiple myeloma (MM) treated with new drug combinations. Despite no substantial myelotoxic effect, thalidomide increases the risk of severe infections in patients with MM. We studied 202 patients who received regimens containing thalidomide in order to assess the time, type, outcome, and factors affecting development of severe infections, role of antibiotic prophylaxis, and effect of severe infections on final outcome. Thirty-eight patients (19%) developed a severe infection early during induction therapy and most infections were pneumonia. Only one patient died due to septic shock during neutropenia. No significant differences were reported in terms of progression-free survival (PFS) and overall survival (OS) between patients developing a severe infection and those who did not. Multivariate analysis determined a monoclonal component >3 g/dL and platelets <130 ,000/µL as factors associated with increased risk of severe infection. Primary antibiotic prophylaxis significantly decreased the probability of severe infection only in patients having both the above risk factors. Patients with MM receiving thalidomide combinations with high tumor burden are at high risk of developing severe infections and require primary antibiotic prophylaxis, whereas in other patients it is questionable. However, patient final outcome was not affected by infection development.

Diffuse large B-cell lymphoma with Homer-Wright rosettes, sinusoidal growth pattern, and CD30 expression: a possible overlap between microvillous lymphomas and sinusoidal CD30-positive large B-cell lymphomas.

Rosette formation is an unusual finding in malignant lymphomas. We herein report another case of a diffuse large B-cell lymphoma (DLBCL) with ultrastructural evidence of cellular projections, sinusoidal growth pattern, and strong CD30 expression. A literature review of the DLBCL cases showing all these features was also performed.

Thalidomide, dexamethasone, and pegylated liposomal doxorubicin (ThaDD) for patients older than 65 years with newly diagnosed multiple myeloma.

We present the results of a phase 2 study using thalidomide, dexamethasone, and pegylated liposomal doxorubicin (ThaDD) in the treatment of 50 patients older than 65 years with newly diagnosed multiple myeloma. Thalidomide 100 mg was administered orally at bedtime continuously, dexamethasone 40 mg was administered orally on days 1 to 4 and 9 to 12, and pegylated liposomal doxorubicin 40 mg/m2 was administered intravenously on day 1 over the 28-day cycle. Response was assessed according to the EBMT criteria. Seventeen (34%) patients achieved CR, 7 (14%) nCR, 5 (10%) VGPR, 15 (30%) PR, and 5 (10%) MR, resulting in an ORR of 98%. Only 1 patient (2%) presented progressive disease. Time to progression (TTP), event-free survival (EFS), and overall survival (OS) projected at 3 years were 60%, 57%, and 74%, respectively, and these parameters were significantly higher in those patients achieving a response of at least VGPR versus those who did not. Grade 3 and 4 nonhematologic adverse events were constipation (10%), fatigue (6%), tremors (4%), mucositis (4%), and palmar-plantar erythrodysesthesia (2%). Grade 3 and 4 neutropenia occurred in 12% of patients. Grade 3 and 4 infections and thromboembolic accidents were observed in 22% and 14% of patients, respectively. In the treatment of elderly patients with newly diagnosed multiple myeloma, ThaDD is a very effective regimen with manageable toxicity.

Salvage therapy with an outpatient DHAP schedule followed by PBSC transplantation in 79 lymphoma patients: an intention to mobilize and transplant analysis.

Chemotherapy followed by autologous transplantation may be an efficient salvage treatment in malignant lymphomas. We investigated the feasibility, tolerability and efficacy of an outpatient schedule of dexamethasone, cytarabine and cisplatin (DHAP), followed by peripheral blood progenitor cell autografting as salvage treatment in patients with high grade (HG), low grade (LG) non-Hodgkin's lymphoma (NHL) and Hodgkin's Disease (HD). A total of 159 DHAP courses (median: 2, range: 1-5), was administered on outpatient basis to 79 patients (31 LG-NHL, 28 HG-NHL and 20 HD), with the intention to mobilize and to transplant. A successful collection was not achieved in 40% LG-NHL, 10% HD and 20% HG-NHL patients. The risk to fail the collection was significantly related to the number of previous chemotherapy courses (>6) (P = 0.005, RR = 1.4), to the pretransplant status (P = 0.04, RR = 13.5) and to the previous fludarabine administration (P = 0.01, RR = 20). High dose therapy (HDT) was feasible in 60 patients (76%). The overall treatment related mortality was 3.8%. The overall response rate (ORR) was 81% with a 57.6% overall survival (OS) at 62 months (95% CI: 45-69.3%) and a progression free survival (PFS) of 42% at 74 months (95% CI: 26.7-58%). The diagnosis of HG-NHL and the non-response to DHAP resulted to reduce respectively the OS (P = 0.007, RR = 2.8) and PFS probability (P = 0.01, RR = 4.1). In conclusion this outpatient schedule of DHAP is a well tolerated, efficient salvage and mobilizing regimen not only in HG-NHL, but also in LG-NHL and in HD. Randomized studies are needed to better define the role of DHAP in LG-NHL and HD patients.
