ESHAP + fixed dose G-CSF as autologous peripheral blood stem cell mobilization regimen in patients with relapsed or refractory diffuse large cell and Hodgkin's lymphoma: a single institution result of 127 patients

From 1996 to November 2004, 131 consecutive patients with relapsed or refractory diffuse large cell lymphoma (DLCL) and Hodgkin's lymphoma (HD) received ESHAP as mobilization chemotherapy before autologous peripheral blood stem cell transplant (ASCT). Patients received fixed dose G-CSF 300 microg SC bid starting 24-36 h after finishing mobilizing ESHAP. In all, four patients failed mobilization and are excluded. Characteristics of 127 patients: 68 males: 59 females. DLCL 49: HD 78. Initial stage I:II:III:IV:unknown was 15:34:33:42:3. Median age at ASCT 26 years. Median prior chemotherapy cycles were six [<6 (17 patients), 6-8 (90 patients), >8 (20 patients)]. Median ESHAP cycle used as mobilizer was third. Patients required 1, 2, 3, 4 apheresis were 93:25:8:1. Median total CD34+ cells/kg collected were 6.9 x 10(6) (DLCL 5.17 x 10(6) and HD 7.6 x 10(6)), patients weighing < or = 70 kg (93 patients) 6.54 x 10(6) and >70 kg (34 patients) 7.44 x 10(6) (P = 0.59), one apheresis (93 patients) 8.6 x 10(6)/kg and >1 apheresis (34 patients) 4.5 x 10(6) (P = 0.001). We conclude that ESHAP and G-CSF 300 microg SC bid is an effective mobilizing regimen even in patients >70 kg and most patients require only 1-2 apheresis.     

ESHAP plus G-CSF as an effective peripheral blood progenitor cell mobilization regimen in pretreated non-Hodgkin's lymphoma: comparison with high-dose cyclophosphamide plus G-CSF

The ESHAP (etoposide, methylprednisolone, high-dose cytarabine, and cisplatin) regimen has been shown to be effective as an active salvage therapy for lymphoma. Mobilizing stem cells following ESHAP should decrease time to transplantation by making separate mobilizing chemotherapy (MC) unnecessary, while controlling a patient's lymphoma. We therefore assessed the mobilization potential of ESHAP plus G-CSF in 26 patients (ESHAP group) with non-Hodgkin's lymphoma (NHL) and compared these results with those of 24 patients with NHL who received high-dose (4 g/m2l) cyclophosphamide (HDCY) as MC (HDCY group). The age, sex, and radiotherapy to the axial skeleton were well matched between groups, but the number of patients with poor mobilization predictors was higher in the ESHAP group. Significantly higher numbers of CD34+ cells (x 10(6)/kg) (17.1+/-18.8 vs 5.8+/-5.0, P=0.03) and apheresis day 1 CD34+ cells (x 10(6)/kg) (5.5+/-6.6 vs 1.7+/-2.0, P=0.014) were collected from the ESHAP group than from the HDCY group, and the number of patients who achieved an optimal CD34+ cell target of 5 x 10(6)/kg was higher in the ESHAP group (81 vs 50%, P=0.022). Log-rank test revealed that time to target peripheral blood progenitor cell collection (> or =5 x 10(6)/kg) was shorter in the ESHAP group (P=0.007). These results indicate that ESHAP plus G-CSF is an excellent mobilization regimen in patients with relapsed and poor-risk aggressive NHL.     

Efficacy of a modified Stanford V regimen in patients with advanced Hodgkin's lymphoma

We report treatment results obtained with a modified Stanford V regimen in 32 patients with advanced Hodgkin's lymphoma (stage II bulky disease, III, IV). Treatment results were not superior to those achieved with conventional treatment (ABVD) in terms of complete remission and survival rates (progression-free survival and overall survival at 3 years: 66% and 91%, respectively).     

Vinorelbine plus intermediate dose cyclophosphamide is an effective and safe regimen for the mobilization of peripheral blood stem cells in patients with multiple myeloma

High dose cyclophosphamide (HD-Cy) is commonly used to mobilize stem cells in multiple myeloma (MM). However, timing of collection is variable and incidence of side effects is substantial. We evaluated a combination of vinorelbine (VNB) (25 mg/m² day 1) plus Cy (1.5 g/m² day 2) and G-CSF as mobilizing regimen in 37 patients with MM. Results were compared to those achieved in 41 previously diagnosed patients mobilized with Cy at 4 g/m². Overall, 36/37 patients receiving VNB–Cy (97%) mobilized, as opposed to 40/41 (97%) in the controls (p:0.51). Median CD34+ cells peak was 94/μl for VNB–Cy patients and 96 for controls, p=0.36; median number of CD34+ cells collected was 9.2×10⁶/kg and 8.7×10⁶/kg, respectively (p=0.85). Median number of days to the highest CD34 count was shorter for VNB–Cy patients (nine vs 11, p=0.001). No VNB–Cy patient experienced grade 3–4 neutropenia and thrombocytopenia, as opposed to 63 and 19% in the controls (p=0.001 and 0.01, respectively). Hospitalization from toxicity was never required in VNB–Cy patients as compared to 19% in control group (p=0.01). We conclude that an outpatient combination of VNB plus intermediate dose Cy plus G-CSF is a safe, predictable, and highly effective mobilization regimen for patients with newly-diagnosed MM.     

A randomized phase 2 study of PBPC mobilization by stem cell factor and filgrastim in heavily pretreated patients with Hodgkin's disease or non-Hodgkin's lymphoma

This randomized, controlled study compared the ability to mobilize and collect an optimal target yield of 5 x 10(6) CD34+ cells/kg using stem cell factor (SCF; 20 microg/kg/day) plus filgrastim (G-CSF; 10 microg/kg/day) vs filgrastim alone (10 microg/kg/day) in 102 patients diagnosed with non-Hodgkin's lymphoma (NHL) or Hodgkin's disease (HD), who were prospectively defined as being heavily pretreated. Leukapheresis began on day 5 of cytokine administration and continued daily until the target yield was reached, or until a maximum of five leukaphereses had been performed. Compared with the filgrastim-alone group (n = 54), the SCF plus filgrastim group (n = 48) showed an increase in the proportion of patients reaching the target yield within five leukaphereses (44% vs 17%, P = 0.002); reduction in the number of leukaphereses required to reach the target yield (P = 0.003); reduction in the proportion of patients failing to reach a minimum yield of 1 x 10(6) CD34+ cells/kg to proceed to transplant (16% vs 26%, P = NS); increase in the median yield of CD34+ cells per leukapheresis (0.73 x 10(6)/kg vs 0.48 x 10(6)/kg, P = 0.04); and an increase in the median total CD34+ cells collected within five leukaphereses (3.6 x 10(6)/kg vs 2.4 x 10(6)/kg, P = 0.05). All patients receiving SCF were premedicated (antihistamines and albuterol), and treatment was generally well tolerated. Five patients experienced severe mast cell-mediated reactions, none of which were life-threatening. In this study of heavily pretreated lymphoma patients, SCF plus filgrastim was more effective than filgrastim alone for mobilizing PBPC for harvesting and transplantation after high-dose chemotherapy.     

Peripheral blood stem cell mobilization using high-dose cyclophosphamide and G-CSF in pretreated patients with lymphoma

Summary. Peripheral blood stem cell (PBSC) mobilization for autologous transplantation is more difficult in treated patients and those with bone marrow involvement. In 17 pretreated lymphoma patients, cyclophosphamide (4 g/m²) and G-CSF mobilized a median circulating peak of 1959 CFU-GM/ml on day 12.5. PBSC harvesting commenced when WBC was 1×10⁹/l at day 10.5 collected a median of 21.2 × 10⁴/CFU-GM/kg. 13/17 (76%) patients exceeded the 10 × 10⁴ CFU-GM/kg threshold for engraftment. The CFU-GM yield was significantly higher in patients whose WBC recovered from 1–5 × 10⁹/1 in less than 3 days and correlated with the maximum WBC pre and post the cyclophospharnide induced nadir. This regime safely mobilized adequate PBSC in the majority of pretreated lymphoma patients.     

Plerixafor is effective and safe for stem cell mobilization in heavily pretreated germ cell tumor patients

Up to 10% of germ cell tumor patients require salvage high-dose chemotherapy with stem cell support, achieving cure rates in the range of 10-60%. Stem cell mobilization may be difficult in these patients because of multiple lines of treatment known to seriously hamper stem cell recovery. Plerixafor significantly enhances the success of the CD34+ cell harvest, even in cases where prior mobilization attempts have failed. Six germ cell tumor patients provided informed consent and were included in the compassionate use program. All patients were heavily pretreated, with a median of 3.5 prior lines of therapy. All failed prior mobilization with G-CSF in combination with chemotherapy. Five patients yielded a median of 2.6 × 10(6) CD34+ cells per kg body weight in a median of 4 apheresis days when plerixafor was used. Three patients underwent subsequent high-dose chemotherapy with autologous stem cell support. Median time to leukocyte engraftment was 11 days. Median time to platelet engraftment was 12.5 days, both of which are comparable to previous historical data. Accordingly, plerixafor seems to be safe and effective in germ cell tumor patients who have failed prior mobilization therapy. Larger prospective studies are warranted to further assess its use in germ cell cancer.     

GEMOX-R regimen is a highly effective salvage regimen in patients with refractory/relapsing diffuse large-cell lymphoma: a phase II study

Objectives:  The prognosis of old or immunocompromised patients with refractory or relapsing diffuse large-cell lymphoma (DLCL) is very poor as the current standard of salvage therapy with autologous stem cell transplantation (ASCT) is not feasible for most of them. New active regimens with an acceptable toxicity profile are needed. We aim to report the results of a phase II trial of the GEMOX-R regimen in DLCL.
Methods:  A total of 32 patients received GEMOX-R regimen in 2-wk intervals if feasible or every 3 wk for a planned six to eight courses.
Results:  Median age of the population was 69 yr. Forty-one percent of the patients were primary refractory and 59% after relapsing. At GEMOX-R, 75% of patients had a stage III–IV and an adjusted International Prognostic Index > 1 was observed in 69%. The response rate was 43% with 34% complete response. Neutropenia and thrombopenia grade III–IV were observed in 43% of the patients and neurotoxicity grade III–IV in 7% of cases. Median follow-up for alive patients was 13 months and the median survival was 9.1 months. At 12 months, the overall survival and progression-free survival were 41% and 29%, respectively.
Conclusions:  GEMOX-R is a new salvage regimen for DLCL with high activity and relatively safe toxicity profile, which can be offered to elderly patients not candidates of ASCT consolidation. The high efficacy of the regimen in this unfavorable population and also in immunocompromised situations warrant further investigation of this regimen in all salvage situations of this type of lymphomas.     

IMVP-16: an effective regimen for patients with lymphoma who have relapsed after initial combination chemotherapy

Results of second-line chemotherapy regimens against lymphoma have usually been poor. In this study, we used a combination of ifosfamide, methotrexate, and VP-16 to treat 52 patients with lymphoma who had either relapsed or who had failed to attain a complete remission on front-line treatment. Thirty-two patients (62%) responded (CR 37%, PR 25%) and 10 (19%) had a minor response. The median relapse-free interval of the responding patients was 12 mo, and the median survival of the whole group was 15 mo. Of the 18 patients who achieved complete remission, 10 still remain free of any evidence of disease. The factor that best predicted for response to IMVP-16 was the quality of the remission achieved on front-line therapy. In view of the poor prognosis associated with recurrent lymphoma, the results obtained with this study are considered most encouraging. Patients with recurrent lymphoma can be successfully salvaged by the use of this combination regimen, especially if introduced early after relapse or preferably before progressive disease develops.     

Gemcitabine,cisplatin and methylprednisolone chemotherapy (GEM-P) is an effective regimen in patients with poor prognostic primary progressive or multiply relapsed Hodgkin's and non-Hodgkin's lymphoma

This study was designed to assess the efficacy and safety of gemcitabine, cisplatin and methylprednisolone (GEM-P) for patients with relapsed or refractory Hodgkin's disease (HD) and non-Hodgkin's lymphoma. Twenty-one patients were treated with gemcitabine (1000 mg/m2 d 1, 8 and 15), cisplatin (100 mg/m2 d 15) and methylprednisolone (1000 mg d 1-5) given every 28 d. Of these, 20 patients were evaluable for response. The median age was 38 years (range 17-64 years). Histological subtypes were: nodular sclerosing HD (n = 10), diffuse large B cell (n = 5), T cell-rich B cell (n = 2), follicular (n = 2), mantle cell (n = 1) and enteropathy-associated T-cell lymphoma (n = 1). The median remission duration prior to receiving GEM-P was only 42 d. The overall objective response rate was 80%[95% confidence interval (CI): 56-94%], including five complete and 11 partial responses. GEM-P induced responses in all histological subtypes, primary progressive disease and patients who had received a previous autograft. The only grade 3-4 toxicity was myelosuppression. However, no cases of febrile neutropenia or haemorrhage with thrombocytopenia were encountered. Median survival has not yet been reached and survival probability at 1 year was 60.8% (95% CI: 31.9-80.5%). In conclusion, GEM-P is a novel combination salvage therapy for poor-prognostic primary progressive or multiply relapsed lymphoma patients. It has clinically significant activity with a favourable toxicity profile.     

Efficacy of vinorelbine, epirubicin and prednisone combination regimen in pretreated elderly patients with aggressive non-Hodgkin's lymphoma

BACKGROUND AND OBJECTIVES: To assess the efficacy and toxic profile of the NAEPP protocol, a regimen including vinorelbine, epirubicin and prednisone, in a particularly troublesome subset of patients: pretreated elderly patients with aggressive non-Hodgkin's lymphoma (NHL). DESIGN AND METHODS: From November 1998 to January 2000, 20 pretreated patients who had all relapsed after first-line VNCOP-B chemotherapy were enrolled in a phase II trial and treated with the NAEPP regimen: vinorelbine (25 mg/m(2) i.v. on days 1 and 8), epirubicin (40 mg/m(2) i.v. on days 1 and 8), and prednisone (40 mg/m(2) on days 1 and 8) with granulocyte colony-stimulating factor administered at 5 mg/kg/day on days 2-5 and days 9-12. Chemotherapy was repeated every 4 weeks for a total of 6 cycles. RESULTS: Six (30%) patients achieved complete remission (CR) and 7 (35%) had partial responses (PR), giving an overall response rate of 65%. The response rate was not affected either by type of relapse presentation (nodal versus nodal plus extranodal), presence of bulky disease, or time of relapse. No major toxic effects were recorded. INTERPRETATION AND CONCLUSIONS: These preliminary data suggest that the NAEPP regimen is an effective combination with a low toxicity profile in elderly pretreated patients with aggressive NHL. Further trials using NAEPP as a consolidation phase following first-line treatment are needed to establish the advantage in terms of CR rate and relapse-free survival in these patients.     

Gemcitabine and vinorelbine combination is effective in both as a salvage and mobilization regimen in relapsed or refractory Hodgkin lymphoma prior to ASCT

We investigated the efficacy of gemcitabine and vinorelbine (Gem/Vin) combination chemotherapy as a salvage and mobilization regimen in relapsed or refractory Hodgkin lymphoma (HL) patients prior to autologous hematopoietic stem cell transplantation. We retrospectively reviewed the data of our relapsed or primary refractory HL patients treated with Gem/Vin regimen which consisted of gemcitabine 1,000 mg/m²/day and vinorelbine 30 mg/m²/day on days 1, 8, and 15 every 28 days. The overall response rate was 72.4%. Ten (34.5%) patients achieved complete remission, 11 (37.9%) partial remission, and eight (27.6%) patients had no response. Mobilization with Gem/Vin regimen was successful in 20/23 (87%) patients while mobilization failure was seen in three (13%) patients. Gemcitabine and vinorelbine is an effective salvage regimen with acceptable toxicity and high mobilization potential in relapsed or refractory HL patients.     

CEPP(B): an effective and well-tolerated regimen in poor-risk, aggressive non-Hodgkin's lymphoma

Eighty-three patients with intermediate- or high-grade non-Hodgkin's lymphoma were treated with CEPP(B) (cyclophosphamide, etoposide [VP- 16], procarbazine, and prednisone with or without bleomycin) chemotherapy at Stanford University Medical Center (Stanford, CA) from January 1982 through June 1989. Sixty-nine received CEPP(B) as second- line or subsequent therapy after relapse from previous combination chemotherapy, and 14 patients received CEPP(B) as first-line therapy. Of 75 patients evaluable for response, 30 patients (40%) achieved a complete response (CR) and 24 patients (32%) achieved a partial response (PR), providing an overall response rate of 72%. Complete responses were recorded on 21 of 61 (34%) patients with recurrent disease and 9 of the 14 patients who received CEPP(B) as first line therapy (64%). Myelosuppression was the major side effect of treatment, resulting in eight neutropenic-febrile episodes from a total of 253 courses. A single fatal toxic event occurred on a patient who developed adult respiratory distress syndrome. Overall, CEPP(B) was well- tolerated and proved to be effective palliative therapy for patients with non-Hodgkin's lymphoma after relapse. As such, CEPP(B) may be considered for cytoreduction before ablative therapy and bone marrow transplantation. CEPP(B) may also be considered for initial therapy in selected patients who cannot tolerate doxorubicin-containing regimens.     

High dose of idarubicin-based regimen for diffuse large cell AIDS-related non-Hodgkin's lymphoma patients: a pilot study

BACKGROUND AND OBJECTIVES: Intensive chemotherapy (CHT) in AIDS-related non-Hodgkin's lymphoma (AIDS-NHL patients) is a vexing problem. Our purpose was to evaluate the feasibility of a high dose idarubicin (HD-IDA)-based regimen in diffuse large cell (DLC) AIDS-NHL patients. DESIGN AND METHODS: Fourteen stage I-IV untreated DLC AIDS-NHL patients with a performance status <3 and no prior AIDS-related diseases received CIOD: cyclophosphamide, HD-IDA (25 mg/m2 in 8 patients, 20 mg/m2 in 6 patients) vincristine and dexamethasone plus granulocyte colony-stimulating factor (G-CSF) and prophylaxis against infections. The outcomes measured were: rate of response, disease-free survival (DFS), overall survival (OS) and the impact of chemotherapy on immunologic and virological parameters. RESULTS: Complete response was achieved in 13/14 cases (response rate: 93%). The median time of response and survival was 33 (range 5-79) and 35.5 (range 6-84) months, respectively. At 60 months the DFS and OS were 71% and 44%, respectively. CIOD with idarubicin 20 mg/m2 was better tolerated than that with 25 mg/m2 and was administered with a higher mean average-relative-dose-intensity (95.38+/-7% vs 83.35+/-15.59%, p=0.0001). Opportunistic infections were more frequent in patients with a baseline CD4 <100 than those with >100 cells/microL (4/5 vs 1/9: p=0.0229). After 3 CIOD courses the mean CD4 cells/microL was significantly lower (p=0.001) and the mean HIV.1 RNA load was significantly higher (p=0.045) than at baseline. INTERPRETATION AND CONCLUSIONS: The proposed chemotherapeutic regimen for AIDS-related non-Hodgkin's lymphoma is feasible in an outpatient setting in selected patients with relatively well-preserved immune function.     

Reduced dose of lenograstim is as efficacious as standard dose of filgrastim for peripheral blood stem cell mobilization and transplantation: a randomized study in patients undergoing autologous peripheral stem cell transplantation

In vitro studies have demonstrated a 27% increased efficacy of lenograstim over filgrastim. However, equal doses of 10 microg/kg/day of filgrastim and lenograstim have been recommended for mobilization of CD34+ cells without associated chemotherapy. In this study, we investigated whether a 25% reduced dose of lenograstim at 7.5 microg/kg/day is equavalent to 10 microg/kg/day filgrastim for autologous peripheral blood stem cell (PBSC) mobilization and transplantation. A total of 40 consecutive patients were randomized to either filgrastim (n = 20) or lenograstim (n = 20). The two cohorts were similar in regard to disease, sex, body weight, body surface area, conditioning regimens, previous chemotherapy cycles and radiotherapy. Each growth factor was administered for 4 consecutive days. The first PBSC apheresis was done on the 5th day. In the posttransplant period, the same G-CSF was given at 5 microg/kg/day until leukocyte engraftment. Successful mobilization was achieved in 95% of patients. Successful mobilization with the first apheresis, was achieved in 10/20 (50%) patients in the filgrastim group versus 9/20 (46%) patients in the lenograstim group. No significant difference was seen in the median number of CD34+cells mobilized, as well as the median number of apheresis, median volume of apheresis, percentage of CD34+ cells, and CD34+ cell number. Leukocyte and platelet engraftments, the number of days requiring G-CSF and parenteral antibiotics, the number of transfusions were similar in both groups in the posttransplant period. Lenograstim 7.5 microg/kg/day is as efficious as filgrastim 10 microg/kg/day for autologous PBSC mobilization and transplantation.     

Ifosfamide and vinorelbine: an active regimen for patients with relapsed or refractory Hodgkin's disease

Twenty-six patients with relapsed or refractory Hodgkin's disease (HD) were treated with an intensive salvage regimen combining ifosfamide (3000 mg/m²/d, days 1–4 through continuous intravenous infusion) and vinorelbine (25 mg/m², i.v. days 1 and 5) with mesna uroprotection and G-CSF support. Courses were given at 3-week intervals.
Ten patients achieved a complete and 10 patients a partial response, yielding an overall response rate of 77%. The main toxic effect was neutropenia and the combination was well tolerated.     

Thrombotic microangiopathy: a complication of Hodgkin's lymphoma in an HIV-infected patient

We report a case of fulminant presentation of thrombotic microangiopathy associated with Hodgkin's lymphoma in an HIV-infected patient. After aggressive therapy with antiretroviral drugs, chemotherapy, and plasmatherapy, complete remission of thrombotic microangiopathy and Hodgkin's lymphoma was observed.
