Continuous infusion ABDIC therapy for relapsed or refractory Hodgkin's disease

Phase II Study of PEND Chemotherapy in Patients with Refractory/Relapsed Hodgkin Lymphoma

High-dose chemotherapy with autologous marrow or stem cell rescue (HDC/ASCT) is an effective strategy in patients with relapsed Hodgkin lymphoma. Various chemotherapy regimens have been used for cytoreduction prior to HDC/ASCT. In this study, our objective was to determine the response rate to PEND in a group of patients with relapsed Hodgkin lymphoma. Nineteen patients with relapsed or primary refractory Hodgkin lymphoma underwent treatment with the PEND regimen and received a median of 2 cycles (1 - 6 cycles). The PEND regimen builds on our prior results with ABDIC and consists of prednisone 40 mg/m2 orally (PO) daily x 5 days; etoposide 50 mg/m2 PO daily x 14 days; mitoxantrone 5 mg/m2/d IV, days 1 and 3; and DTIC 200 mg/m2/d intravenous continuous infusion (CIV) over 24 h, days 1 to 5, via central venous catheter. The treatment was given every 28 days. There were 3 complete responses (16%) and 10 partial responses (53%) yielding a total response rate of 69% (95% C.I. 43%, 87%). Myelosuppression was the predominant toxicity; no deaths were due to toxicity. After achieving maximum response to PEND, 10 eligible patients received a consolidative treatment with HDC/ASCT. All 6 patients who did not respond to PEND died from disease progression whereas 5 of 13 responders were alive after 10 years of follow-up (3 without disease). There were 11 deaths due to disease progression; three from other causes. The initial response to PEND before subsequent ASCT consolidation treatment appears to be associated with survival. All patients who failed to achieve a response have died. We conclude that PEND is an effective treatment strategy in Hodgkin lymphoma patients previously treated with both ABVD and MOPP.

Chemotherapy followed by low dose radiotherapy in childhood Hodgkin's disease: retrospective analysis of results and prognostic factors

Purpose

To report the treatment results and prognostic factors of childhood patients with Hodgkin's disease treated with chemotherapy (CT) followed by low dose radiotherapy (RT).

Patients and methods

This retrospective series analyzed 166 patients under 18 years old, treated from January 1985 to December 2003. Median age was 10 years (range 2–18). The male to female ratio was 2,3 : 1. Lymphonode enlargement was the most frequent clinical manifestation (68%), and the time of symptom duration was less than 6 months in 55% of the patients. In histological analysis Nodular Sclerosis was the most prevalent type (48%) followed by Mixed Celularity (34.6%). The staging group according Ann Arbor classification was: I (11.7%), II (36.4%), III (32.1%) and IV (19.8%). The standard treatment consisted of chemotherapy multiple drug combination according the period of treatment protocols vigent: ABVD in 39% (n-65) of the cases, by VEEP in 13 %(n-22), MOPP in 13 %(n-22), OPPA-13 %(n-22) and ABVD/OPPA in 22 %(n-33). Radiotherapy was device to all areas of initial presentation of disease. Dose less or equal than 21 Gy was used in 90.2% of patients with most part of them (90%) by involved field (IFRT) or mantle field.

Results

The OS and EFS in 10 years were 89% and 87%. Survival according to clinical stage as 94.7%, 91.3%, 82.3% and 71% for stages I to IV(p = 0,005). The OS was in 91.3% of patients who received RT and in 72.6% of patients who did not (p = 0,003). Multivariate analysis showed presence of B symptoms, no radiotherapy and advanced clinical stage to be associated with a worse prognosis.

Conclusion

This data demonstrating the importance of RT consolidation with low dose and reduced volume, in all clinical stage of childhood HD, producing satisfactory ten years OS and EFS. As the disease is highly curable, any data of long term follow-up should be presented in order to better direct therapy, and to identify groups of patients who would not benefit from radiation treatment.

Salvage therapy of progressive and recurrent Hodgkin's disease: results from a multicenter study of the pediatric DAL/GPOH-HD study group

PURPOSE

To evaluate a salvage therapy (ST-HD-86) for patients with progressive and relapsed Hodgkin's disease after primary treatment in the pediatric DAL/GPOH studies. The essential chemotherapeutic regimens were ifosfamide, etoposide, and prednisone (IEP) and doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD).

METHODS

One hundred seventy-six patients with progression (n = 51) or first relapse (n = 125) were enrolled by 67 centers. The median time from initial diagnosis to progression/relapse was 1.1 year (range, 0.1 to 15.3 years), and the patients' median age was 14.7 years (range, 4.3 to 24.5 years). Salvage chemotherapy consisted of two to three cycles of IEP alternating with one to two cycles of ABVD supplemented in part by one to two cycles of cyclophosphamide, vincristine, procarbazine, and prednisone or lomustine (CCNU), etoposide, and prednimustine. Radiotherapy was given to involved areas using individualized doses. In the 1990s, additional high-dose chemotherapy with autologous stem-cell transplantation (SCT) was introduced for patients with unfavorable prognosis.

RESULTS

Disease-free survival (DFS) and overall survival (OS) after 10 years are 62% and 75%, respectively (SE, 4% each). Of 176 patients, 73 suffered second events. The risk-factor analysis revealed the time to progression/relapse as the strongest prognostic factor (P = .0001). Patients with progression have an inferior outcome (DFS, 41%; OS, 51%), whereas patients with late relapse (> 12 months after end of therapy) do well (DFS, 86%; OS, 90%), although none of them received SCT in second remission.

CONCLUSION

The result can be considered favorable. Whereas the salvage strategy for progressive disease has to be optimized further, it is possible to reduce intensity and avoid SCT in late relapses after Hodgkin's disease in childhood/adolescence.

Activity of infusional etoposide, vincristine, and doxorubicin with bolus cyclophosphamide (EPOCH) in relapsed Hodgkin's disease

INTRODUCTION

A phase II study of EPOCH chemotherapy in relapsed Hodgkin's disease was performed in 14 patients in a multicenter community setting. Patients and Methods. A total of 14 patients (9 males and 5 females) were included in the study. Ages ranged from 21-72 with a median age of 33. Eleven out of 14 patients had advanced (stage III or IV) disease, but all patients had good performance status. All 14 patients had received prior chemotherapy with ABVD, MOPP, or MOPP/ABVD hybrid.

RESULTS

A total of 57 cycles of EPOCH were administered during this trial. Patients received a median of four cycles of chemotherapy. An overall response rate of 86% was seen among the 14 patients with one patient achieving a complete response. Following EPOCH chemotherapy, 7 of 12 patients who responded underwent high-dose chemotherapy with stem cell support. Six out of 14 patients are currently alive, and three had no evidence of disease at the time of last follow-up. Toxicity with EPOCH chemotherapy consisted mainly of myelosuppression, and most patients were managed on an outpatient basis.

CONCLUSION

This multicenter community study confirms the activity of EPOCH chemotherapy in the treatment of patients with relapsed Hodgkin's disease.

High dose ifosfamide in combination with etoposide and epirubicin followed by autologous stem cell transplantation in the treatment of relapsed/refractory Hodgkin's disease: a report on toxicity and efficacy

Patients with Hodgkin's disease (HD) refractory to first line chemotherapy and those who have rapid or multiple relapses have a very poor prognosis. With the increasing use of hybrid chemotherapy these patients will have been exposed to many of the drugs active in HD so it is important to develop salvage regimens that are novel and demonstrate activity in this group of patients. We report the use of a continuous high dose infusion of ïfosfamide at a dose of 9g/m(2) over 3 days in combination with etoposide and epirubicin followed by autologous stem cell transplant with either BEAM or Melphalan/VP16 conditioning in this difficult group. Forty six patients (28M:18F) with a median age of 28 years (range 13-45) were treated. Overall 39 out of 46 (85%) patients responded to treatment, with 17 achieving complete remission and 11 a good partial remission; 28 proceeded to autologous bone marrow/stem cell transplantation. In total, 23 patients are alive and in continuous remission with a follow up of between 12 and 61 months. Median overall survival for the whole group is 36 months. Haematological toxicity, particularly neutropenia (WHO grade IV), was observed in all cases but improved over the 3 courses of treatment in all patients. Non-haematological toxicity was not a major problem; no significant cardiac, hepatic, renal, pulmonary or neuro toxicity was observed and there were no deaths on treatment. This regime shows promise in patients with difficult Hodgkin's disease and warrants further study.

Treatment of relapsed Hodgkin's disease: strategies and prognostic factors

The major points in salvage therapy of patients in relapse following combination chemotherapy for advanced disease are: (1) success of any second-line approach is determined by prognostic factors which include age, duration of the initial remission, and quantity of disease at relapse; (2) induction failures (progression without remission or incomplete remission and short initial remission) require innovative therapy which currently entails high-dose chemotherapy with peripheral or bone marrow autologous support; (3) late relapse still retains an order to sensitivity to chemotherapy and can be treated with conventional dose combination with complementary radiation therapy to previously unirradiated bulky sites. The choice of regimen is empiric and can include a repeat of the regimen used for the original remission or induction. The relative advantage of HDC in this favorable group is uncertain.

Intensive therapy and autotransplant for patients with an incomplete response to front-line therapy for lymphoma

BACKGROUND

Patients with Hodgkin's disease (HD) and intermediate or high-grade non-Hodgkin's lymphoma (NHL) who fail to achieve a complete remission (CR) with standard induction therapy have a poor prognosis with conventional-dose salvage therapy alone. We examined the role of subsequent intensive therapy and autologous bone marrow transplantation (ABMT) in patients who demonstrated a response to conventional-dose therapy.

PATIENTS AND METHODS

Sixty-six patients with either HD (n = 30) or NHL (n = 36) underwent intensive therapy with etoposide (60 mg/kg), intravenous melphalan (160-180 mg/m2) followed by infusion of unpurged autologous bone marrow and/or blood cells. All patients had advanced stage or bulky disease at diagnosis and failed to achieve a CR after an anthracycline-containing front-line chemotherapy regimen (NHL) or ABVD or equivalent regimen (HD). Patients who achieved a CR after involved-field radiotherapy were excluded. All patients demonstrated sensitivity to conventional-dose salvage treatment before advancing to intensive therapy and ABMT.

RESULTS

The CR, partial response (PR) and overall response rate (RR) following ABMT for HD patients was 48%, 17% and 65%, respectively. At a median follow-up of 35 months, the predicted three-year overall survival (OS) is 51% (95% CI: 44%-60%) and event-free survival (EFS) is 34% (95% CI: 26%-54%). For patients with NHL, the CR, PR and RR were 68%, 9% and 77%, respectively. At a median follow-up of 28 months, the predicted three-year OS is 51% (95% CI: 35%-66%) and EFS is 39% (95% CI: 21%-57%).

CONCLUSIONS

Intensive therapy with etoposide and melphalan followed by ABMT results in prolonged survival in selected patients with lymphoma who fail to achieve a complete remission to front-line chemotherapy. Based on our previous studies of outcome to conventional-dose salvage chemotherapy, we estimate that of all patients failing induction therapy, 28% with HD and 15% with NHL will be event-free at three years after ABMT.
