Ten-year results of a strategy combining three cycles of ABVD and high-dose extended irradiation for treating Hodgkin's disease at advanced stages

Efficacy and safety of front-line treatments for advanced Hodgkin lymphoma: a systematic literature review

OBJECTIVE

To assess evidence on the safety and efficacy of ABVD (doxorubicin [Adriamycin®], bleomycin, vinblastine, and dacarbazine), BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone), and A+AVD (brentuximab vedotin, with doxorubicin, vinblastine, and dacarbazine) for advanced-stage Hodgkin lymphoma (HL).

METHODS

A systematic literature review (SLR) was conducted on 29 July 2016 (updated 26 July 2018) to identify randomized controlled trials (RCTs) and non-RCTs assessing the treatment of newly-diagnosed advanced-stage HL with ABVD and BEACOPP (and their variants), and A+AVD.

RESULTS

The SLR identified 62 RCTs and 42 non-RCTs. Five-year overall survival rates for ABVD and BEACOPP were 60-97% and 84-99%, and 5-year progression-free survival rates were 58-81% and 83-96%, respectively. Both regimens were associated with tolerability issues and side effects. Discontinuation or dose reduction of bleomycin resulted in fewer adverse events, without significantly affecting efficacy. A head-to-head trial demonstrated improved efficacy for A+AVD vs ABVD, with an acceptable tolerability profile. No data from head-to-head trials comparing A+AVD with BEACOPP were available, and an indirect treatment comparison was not feasible.

CONCLUSION

New therapies, such as A+AVD, maintain the efficacy observed with current treatments, and may provide a more tolerable treatment option for patients with advanced-stage HL.

Radiation Therapy Induced Cardiovascular Disease

Contemporary treatment modalities for malignancy including radiation therapy have led to improved survival. However treatment related complications manifesting later in life including cardiovascular disease has led to survivors exhibiting a lower long term survival rate, when compared to age matched controls. This narrative review will discuss the pathophysiology, risk factors, clinical presentation, management and preventative techniques related to radiotherapy-induced cardiotoxicity.

Twenty-year disease and treatment-associated mortality rates of patients with Hodgkin lymphoma of clinical stages IIIB and IV prospectively treated with 3-month anthracycline-based chemotherapy followed by extended high-dose radiation

BACKGROUND

In 1981, the authors developed an original strategy combining 3 cycles of doxorubicin (adriamycin), bleomycin, vinblastine, and dacarbazine (ABVD) or ABVD-like chemotherapy and extended high-dose radiation for treating patients with clinical stages IIIB and IV Hodgkin lymphoma (HL). In the current study, the authors analyzed the 20-year results of this treatment as applied to 213 patients according to 2 successive trials.

METHODS

All patients who responded to chemotherapy received extended high-dose radiation. The rates of complete remission (CR), freedom from disease progression (FFP), HL-specific survival (HLSS), second tumors and cardiac events, freedom from treatment-associated mortality (FFTM), overall survival (OS), and event-free survival were calculated.

RESULTS

In December 2006, the median follow-up of the surviving patients exceeded 13 years; 102 patients (48%) achieved a CR after chemotherapy and 178 patients (84%) did so after radiotherapy. The rates of FFP (61%, quasi-stable after 6 years) and HLSS (81.6%, stable after 12 years) were found to be significantly higher in patients who achieved a CR after chemotherapy. The incidence of hematologic malignancies was 10.9% (with 10 of 12 events occurring within the first 7 years). The rates of solid tumors (32.4%), cardiac events (33.4%), and FFTM (65.6%) did not reach any plateau by 20 years and were found to be significantly associated with patient age. The 20-year OS rate was 48%.

CONCLUSIONS

This combined modality treatment gave long-term results similar to those obtained using 6 to 8 cycles of ABVD. Response to the initial brief chemotherapy administration was found to be predictive of the FFP and HLSS rates. The low rate of FFTM was the result of extended high-dose radiation. The results of the current study should help to design future trials for treating patients with advanced stages of HL.

Predictive and discriminating three-risk-group prognostic scoring system for staging Hodgkin lymphomas

BACKGROUND

Several 3-stage Ann Arbor classification-derived prognostic systems were constructed since 1980 to identify the prognosis of Hodgkin lymphoma (HL). Modern statistical tools were applied to 955 patients treated between 1981 and 1996 to build a 3-stage prognostic scoring system (PSS).

METHODS

Each variable associated with 10-year overall survival (10-year OS) was assigned to 2 (0 or 1) or 3 (0, 1 or 3) values. By summing the values attributed to each variable, 3 stages were defined. 10-year OS, 5-year event-free survival (5-year EFS), and freedom from progression (5-year FFP) rates of the PSS and of other existing systems were then compared.

RESULTS

Four variables were associated with 10-year OS: age (<40 = 0, >or=40 = 1), number of involved lymphoid areas (1-2 = 0, 3-4 = 1, >or=5 = 2), visceral disease (no = 0, yes = 1), and systemic symptoms (no = 0, yes = 1). Scores 0 and 1, 2 and 3, and >or=4 were attributed to 59.7%, 30.9%, and 9.4% of the patients who had 10-year OS rates of 93.5, 75.7, and 53.4% and 5-year EFS / 5-year FFP rates of 91.2%/90.3%, 78.1%/76.3%, and 54.1%/52.6%, respectively. The discrimination and prediction abilities of the PSS were better than those of the other systems tested; moreover, the PSS adequately identified the few patients with a worse prognosis without resorting to the International Prognostic Score for advanced stages. The PSS was also highly predictive for 489 patients treated between 1997 and 2002.

CONCLUSION

PSS is a useful alternative to the existing prognostic systems for evaluating HL patients.

Mid- and post-ABVD gallium scanning predicts for recurrence in early-stage Hodgkin's disease

PURPOSE

To determine the efficacy of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) for patients with Hodgkin's disease and to identify predictors of outcome with this regimen.

METHODS

Between 1987 and 1998, 175 patients with Stage I-IV Hodgkin's disease received ABVD as part of initial treatment. Overall survival (OS), freedom-from-treatment-failure (FFTF), and progression-free survival (PFS) were calculated using the Kaplan-Meier technique. Log-rank tests were used to identify univariate predictors of OS, FFTF, and PFS. Specifically, restaging gallium scan results and clinical response after chemotherapy were separately evaluated.

RESULTS

The median follow-up time was 64 months. The 5-year OS, FFTF, and PFS rates were 90%, 85%, and 82%, respectively. For Stage I-II patients, restaging gallium scan results and clinical response after chemotherapy were highly predictive of OS, FFTF, and PFS (p < 0.0001). Other significant predictors for higher OS included age <50 (p = 0.002), female gender (p = 0.047), and absence of B symptoms (p = 0.043). Of the 20 patients with a positive restaging gallium scan, 4 received high-dose therapy and 16 continued with conventional-dose therapy or received no further treatment. Of these 16 patients, 11 (69%) were disease-free at last follow-up.

CONCLUSIONS

Although a positive mid- or postchemotherapy gallium scan was an adverse prognostic factor for OS, FFTF, and PFS, continued treatment with conventional-dose therapy may be adequate in selected patients with positive scans.

Analysis of treatment results in advanced Hodgkin's disease: the case for adjuvant radiotherapy

PURPOSE

To assess the treatment results in patients with advanced Hodgkin's disease in a single center and to evaluate the clinical and therapeutic prognostic factors, including verification of the significance of the prognostic score.

METHODS AND MATERIALS

Treatment results were analyzed in 133 patients with newly diagnosed Stage IIIB and IV Hodgkin's disease. Treatment consisted of six courses of hybrid chemotherapy (mechlorethamine, vincristine, procarbazine, and prednisone [MOPP]/doxorubicin (adriamycin), bleomycin, and vincristine [ABV]) followed by irradiation (RT) in patients with an indication for RT (84 patients). Chemotherapy was then continued for another two cycles. The indications for consolidation RT included bulky disease and/or partial response after six cycles of chemotherapy. In 31 patients, extended-field RT was performed, and in 53, limited fields were irradiated. The median radiation dose was 39 Gy.

RESULTS

The median follow-up was 78 months. Complete remission after whole treatment was achieved in 88.7% of patients. The actuarial overall survival rate was 78% and 71%, and relapse-free survival rate was 73% and 65% at 5 and 10 years, respectively. The independent adverse prognostic factors in multivariate analysis appeared to be older age, low serum albumin, low serum gammaglobulin, lower number of chemotherapy cycles, and no RT. The value of the prognostic score was confirmed; the higher the prognostic score, the worse the survival.

CONCLUSION

In patients with advanced Hodgkin's disease, consolidation RT improved survival. The best results were achieved with the use of large-volume RT.

Primary systemic treatment of advanced Hodgkin's disease with EVA (etoposide, vinblastine, doxorubicin): 10-year follow-up

BACKGROUND

The most commonly used regimen for the treatment of advanced Hodgkin's disease (HD) is ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine). Two of these components, bleomycin and dacarbazine, have defined toxicities such as pulmonary fibrosis and nausea/vomiting, and also uncertain single-drug activity. The EVA regimen (etoposide, vinblastine, doxorubicin) is an attempt to substitute a known active agent, etoposide, for bleomycin and dacarbazine.

PATIENTS AND METHODS

A series of 51 patients with advanced HD without prior systemic therapy were treated. The series included 12 stage II patients with bulky (>10 cm) mediastinal tumors, 10 of whom received complementary radiation therapy. The remaining patients received EVA only. Response, duration of response, survival, toxicity and the efficacy of salvage therapy were evaluated in all patients. The median follow-up time was 111 months and permitted an assessment of the long-term effects of treatment and natural history of a cohort of treated patients.

RESULTS

EVA achieved a complete response (or clinical complete response) in 48/51 patients (94%). Of these 48 responders, 16 relapsed in a median of 11 months (range 3-48 months). In follow-up, 32/51 patients had no evidence of relapsed HD, although three died from other causes (two from vascular events and one from large cell lymphoma), resulting in progression-free survival for the entire group of 57% at 111 months. Eight of the 16 were alive and free from disease at follow-up at 111 months. In the entire series, only seven patients (14%) died of HD. 37 patients (73%) continued free from disease. There was no pulmonary toxicity.

CONCLUSIONS

The EVA regimen appears to have an overall survival (OS) outcome comparable to ABVD, but without the lung toxicity. The high salvage rate of second-line therapy, in most instances at conventional dosage, suggests an absence of cross-resistance to alkylating agents in patients treated with EVA.

Treatment of patients with advanced or bulky Hodgkin disease with a 12-week doxorubicin, bleomycin, vinblastine, and dacarbazine-like chemotherapy regimen followed by extended-field, full-dose radiotherapy: long-term results of the Groupe Ouest et Est des Leucémies et Autres Maladies de Sang H90-A/B Multicenter Randomized Trial

BACKGROUND

This Phase II study was performed in patients with advanced or bulky Hodgkin disease (HD) to evaluate the results of a 7-drug chemotherapy (CT) regimen that was administered over 12 weeks according to 2 randomized modalities followed by high-dose lymph node irradiation.

METHODS

From 1990 to 1996, 162 patients with HD at clinical stages (CS) I-III with bulky disease (mediastinal mass ratio >or= 0.45 and/or unilateral or bilateral pelvic plus lumboaortic disease; 86 patients) or CS IV (76 patients) were randomized to receive the same cumulated dose of a CT regimen consisting of epirubicin (240 mg/m(2)), bleomycin (60 mg/m(2)), vinblastine (20 mg/m(2)), vincristine (4 mg/m(2)), cyclophosphamide (4000 mg/m(2)), etoposide (900 mg/m(2)), and methotrexate (180 mg/m(2)) plus methylprednisolone (1500 mg/m(2)) over 12 weeks either every 4 weeks (Arm Y, 79 patients) or every 3 weeks (Arm Z, 83 patients). Patients with disease in complete remission (CR) or partial remission after CT received extended-field lymph node irradiation (involved areas, 40 grays [Gy]; noninvolved areas, 30 Gy).

RESULTS

Forty-two percent of patients achieved a post-CT CR, and 86% of patients achieved a CR after the completion of irradiation (there was no difference between Arm Y and Arm Z). Thirty-five patients developed recurrent disease; most of those patients were in post-CT partial remission. The 10-year freedom from first progression rate was 63.9% (there was no difference between Arm Y and Arm Z). Thirty-eight patients died: 24 patients from HD, 3 patients from CT-related early sepsis, 1 patient from radiation-induced pneumonitis, 6 patients from a second malignancy, and 4 patients from causes unrelated to treatment. The overall 10-year survival rate was 76.7%. Survival was slightly higher among patients in Arm Y (83.3%) compared with patients in Arm Z (70.2%; P = 0.12).

CONCLUSIONS

No differences were found when the same amount of CT was delivered in three courses or in four courses. In 1997, because most recurrences of the H90-A/B trial occurred in patients who achieved a post-CT partial remission, the authors decided to reinforce the intensity of the initial CT and designed a new randomized study comparing two modalities of more intensive CT plus consolidative radiotherapy (H97-LM trial).

Fifteen-year secondary leukaemia risk observed in 761 patients with Hodgkin's disease prospectively treated by MOPP or ABVD chemotherapy plus high-dose irradiation

Between 1972 and 1988, 869 adult patients received MOPP (mechlorethamine, vincristine, procarbazine and prednisone; 462 patients) or ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine; 373 patients) and subsequent high-dose irradiation for Hodgkin's disease. Nine patients developed a leukaemia after MOPP and four after ABVD; 11 patients were diagnosed as acute non-lymphoblastic leukaemia (ANLL) and two as acute lymphoblastic leukaemia (ALL). Both cases of ALL were observed after ABVD and were associated with a 11q23 translocation. The 15-year actuarial risk of secondary leukaemia was 2.4% for the whole group of patients, 3.4% after MOPP and 1.3% after ABVD. For the MOPP subgroup, the risk of leukaemia was significantly associated with the extent of irradiation: 2.4% for limited irradiation and 13.9% for extended irradiation (P < 0.001). For the ABVD subgroup, this risk remained low (1.3%) whatever the type of irradiation. Concerning ANLL, the MOPP regimen was significantly associated with a higher risk: 3.4% versus 0.7% for ABVD (P<or=0.05). The 15-year risk of ALL was 0.6 after ABVD regimen. This study demonstrated that ABVD induced less ANLL than MOPP. However, a low risk of ALL with a 11q23 translocation related to topoisomerase II inhibitors was observed.

Front-line high-dose therapy with autologous stem cell transplantation for high risk Hodgkin's disease: comparison with combined-modality therapy

This retrospective study compares high-dose therapy (HDT) with autologous stem cell transplantation and combined-modality treatment (CT) as a first-line therapy for Hodgkin's disease (HD) for patients with both a clinical stage (CS) IV and/or a mediastinal mass > or =0.45 of the thoracic diameter (MM > or =0.45) at diagnosis, and an incomplete response after the first-line chemotherapy. Data on 42 grafted patients (GP) in Nantes Hospital, France and on 108 combined-modality treated patients (CTP) from two protocols of the GOELAMS group, France (POF 81 and H90) was analyzed. Both groups were comparable except for pulmonary disease in excess in the grafted group (P = 0.01). Among GP, 95% were in complete response at the end of first-line treatment and 77% among CTP. Median follow-up was 53 months (range, 7 to 128 months) for GP and 88 months (range, 25 to 181 months) for CTP. The 5-year freedom from progression (FFP) and event-free survival (EFS) rates were better for GP (87% vs 55% for FFP: P = 0.0004 and 81% vs 51% for EFS: P = 0.0004) whereas the overall survival (OS) rates did not differ significantly (85% for GP vs 71% for CTP: P = 0.06). Similar results were obtained for the groups with a response > or =50% after initial chemotherapy: 91% vs 65% for FFP, P = 0.01; 87% vs 61% for EFS, P = 0.02; and 92% vs 77% for OS, P = 0.2; and for the groups with a response <50%: 80% vs 22% for FFP, P = 0.0003; 72% vs 13% for EFS, P = 0.0001; and 76% vs 46% for OS, P = 0.04. This study shows a better control of the disease with HDT.

Prognostic factors in advanced stage Hodgkin's lymphoma: the significance of the number of involved anatomic sites

BACKGROUND

Advanced Hodgkin's lymphoma (HL) is curable by conventional chemotherapy in 60--70% of patients. The pretreatment identification of a sizeable subgroup of patients with sufficiently low failure-free survival (FFS) to be eligible for investigational treatment is necessary.

OBJECTIVES

To determine the prognostic significance of the number of involved sites (NIS) in patients with advanced HL and its relationship to the International Prognostic Score (IPS).

METHODS

A retrospective review of patients with advanced HL, defined as Ann Arbor stage (AAS) IB, IIB, III or IV, treated with anthracycline-based regimens. The end-point was FFS.

RESULTS

We identified 277 patients with a median age of 32 yr (14--78), 57% of whom were males. AAS was I in 4% of patients, II in 29%, III in 38% and IV in 29%. B-symptoms were recorded in 81%. Most patients had nodular sclerosis (64%) and mixed cellularity (26%) histology. IPS was greater-than-or-equals 3 in 44% of 242 evaluable patients. The NIS was greater-than-or-equals 5 in 32% of the patients and 20% of all patients had both greater-than-or-equals 5 involved sites and IPS greater-than-or-equals 3. The 10-yr FFS was 67%, being 76% vs. 50% for patients with less-than-or-equals 4 vs. greater-than-or-equals 5 involved sites (P < 0.0001). The NIS (greater-than-or-equal 5), AAS IV and anemia were independent predictors of FFS in multivariate analysis. The NIS remained significant along with IPS, when the latter was included in the analysis. Patients with greater-than-or-equals 5 involved sites and IPS greater-than-or-equals 3 had 10-yr FFS overall, and relapse-free survival of 41%, 45% and 49%, respectively.

CONCLUSIONS

The NIS was associated with FFS in advanced HL, was independent of IPS, and led to the identification of a sizeable subgroup of patients with 10-yr FFS of approximately 40%. This factor should be evaluated during the development of prognostic systems.

Sequential chemotherapy (etoposide, vinblastine, and doxorubicin) and subtotal lymph node radiation for patients with localized Hodgkin disease and unfavorable prognostic features: A phase II Cancer and Leukemia Group B Study (9051)

BACKGROUND

The aim of this study was to evaluate a regimen of sequential chemotherapy and radiotherapy for patients with Hodgkin disease.

METHODS

The Cancer and Leukemia Group B conducted a Phase II study of three cycles of etoposide, vinblastine, and doxorubicin (EVA) chemotherapy followed by subtotal lymph node radiation for patients with localized Hodgkin disease and unfavorable prognostic features. Fifty-nine patients were enrolled in the study. Fifty-three patients met all study eligibility criteria; 48 of them (91%) had mediastinal disease and 29 (55%) had bulky mediastinal disease.

RESULTS

A complete response (CR) occurred in 35 of the patients (66%). Of all patients who had CR, 26% had the CR after the chemotherapy and before the radiation, and 74% after the chemotherapy and radiation. Twenty percent of the patients who had CR experienced disease progression; in these patients, the progression was outside the radiotherapy field in the lung and involved widespread disease.

CONCLUSIONS

EVA offers a nonbleomycin-containing alternative for patients in whom preexisting pulmonary disease may be exacerbated by bleomycin and radiation therapy. EVA, as given in this study (in three cycles), was insufficient chemotherapy for patients who had disease in areas outside the radiation fields (occult disease).
