Hodgkin's disease, clinical stages IA to IIIB: combined modality therapy (3 MOPP followed by curative and prophylactic radiotherapy including the spleen). Six-year results

From January 1980 to September 1985, 82 patients with IA to IIIB clinical stage (CS) Hodgkin's disease were treated by three MOPP chemotherapy (CT) cycles followed by extended field radiotherapy (RT) including the spleen (30-40 Gy). 2 patients died during the treatment (medullary aplasia, pulmonary edema). 6 were in failure after three MOPP cycles; they received other CT; 3 died and 3 are alive in remission (survival: 2.5 to 3.5 yr). 74 were in complete remission (CR) after completion of treatment. 4 patients relapsed (all alive after re-treatment) and 4 died in first CR (tuberculosis, hepatitis, myeloma, unknown cause). At 6 yr, actuarial survival and relapse-free survival are respectively 89.8% for the 82 patients and 93% for those in CR. These good results are due to: the administration of CT before RT, limited to three cycles; identification of failures after CT; inclusion of the spleen in RT ports in all cases; and a short lumbo-aortic port in CS I and II.     

A population-based study of the outcome for patients with first relapse of Hodgkin's lymphoma

BACKGROUND: Our aims were to evaluate the response to salvage treatment in relation to initial treatment and to evaluate prognostic factors at the time of relapse in an unselected population of relapsing patients with Hodgkin's lymphoma (HL). PATIENTS AND METHODS: In total, 124 patients younger than 60 yr of age with initial diagnosis of HL in Sweden relapsed between 1985 and 1995. RESULTS: Fifty-eight patients relapsed after initial treatment with radiotherapy (RT) only, 62 after combination chemotherapy (CT), of whom 30 had received additional involved-field RT, and four after a short course of CT followed by extended-field RT. For 37 patients among the 58 relapsers after initial RT treated according to the recommendations of the National guidelines, the 5-yr Hodgkin-specific survival (HLS) was 85%, overall survival (OS) 73% and event-free survival (EFS) 62%, which is not inferior to survival in patients with primarily advanced stages. It was poorer in the 21 patients who initially had received RT only, even though they had been recommended for more extensive treatment. For patients initially treated with a full course (6-8 cycles) of CT the 5-yr HLS was 60%, OS 58% and EFS 22%. Bulky disease and age at diagnosis strongly affected survival in a multivariate analysis. CONCLUSIONS: Patients initially treated with RT who relapse have a favourable outcome, provided they have been treated according to the recommendations of the guidelines at the time of diagnosis. Initially bulky disease and, as a consequence, additional RT as part of the initial treatment negatively affect survival at relapse in patients initially treated with a full course of CT.     

ChlVPP/ABVVP, a first line 'hybrid' combination chemotherapy for advanced Hodgkin's lymphoma: a retrospective analysis

We retrospectively analysed toxicities and clinical results of 61 Hodgkin's lymphoma patients treated with chlorambucil, vinblastine, procarbazine, doxorubicin, bleomycin, vincristine and etoposide (ChlVPP/ABVVP), delivered in a weekly alternate schedule. Of 61 patients, 33 were in stages III-IV, 21 in stage IIB and seven in stage IIA with bulky disease or extranodal presentation. ChlVPP/ABVVP was administered for 6-8 cycles. Involved field radiotherapy (IFRT) (30-35 Gy) was delivered to 31 patients with residual disease after chemotherapy or bulky disease at diagnosis. Of 61 patients, 58 (95%) achieved complete clinical or radiological remission after chemotherapy and IFRT. With a median follow-up of 60 months, 5-year overall survival, relapse- and event-free survival were 78.8% (95% CI 68.2-91.1%), 81% (95% CI 70.6-92.2%) and 71.9% (95% CI 68.2-82.2%) respectively. Grades 3-4 neutropenia was the most relevant haematological toxicity and occurred in 82% of patients. Non-haematological toxicities were mild and reversible. No toxic deaths were recorded. One patient developed secondary acute myeloid leukaemia 1 year after ChlVPP/ABVVP. Due to the retrospective nature of this study, no definitive conclusions could be drawn about the clinical activity of ChlVPP/ABVVP. Nonetheless, clinical results seem better than those reported with standard regimens [ABVD (doxorubicin, bleomycin, vincristine, dacarbazine), MOPP (methotrexate, vincristine, procarbazine, prednisone), MOPP/ABVD] and as good as those reported using standard or escalated BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine and prednisone), with a lower degree of haematological and non-haematological toxicity. Long-term results of the ongoing randomized trial, comparing ABVD versus high-dose intensity weekly regimens will be useful to confirm our results.     

Risk of infertility in patients with Hodgkin's disease treated with ABVD vs MOPP vs ABVD/MOPP.

The gonadal function of 38 patients with Hodgkin's disease (HD) treated with MOPP chemotherapy (12 patients), ABVD (9 patients) and alternating MOPP/ABVD (17 patients) has been retrospectively investigated with semen analysis. Median age of patients was 25 years (range 16-41 years). Azoospermia was found in all patients from the MOPP group (100%), in 3 of the ABVD group (33%) and in 13 of the MOPP/ABVD group (76%). After temporary oligospermia full recovery of spermatogenesis was observed in 67% of patients treated with ABVD, versus 25% of MOPP-treated patients following a prolonged period of azoospermia and oligospermia. Patients receiving MOPP/ABVD scheme had complete recovery of testicular function after oligospermia in 24% of cases. These results confirm the higher gonadal toxicity of the MOPP regimen as compared to others such as ABVD without alkylating agents.     

Salvage chemotherapy in Hodgkin's disease irradiation failures: superiority of doxorubicin-containing regimens over MOPP

One hundred and twenty-two consecutive patients with Hodgkin's disease who relapsed after primary curative irradiation were treated with either MOPP (mechlorethamine, vincristine, procarbazine, and prednisone) or a doxorubicin-containing regimen (ADM-Reg). The main pretreatment characteristics were comparable in the two groups. Complete remission was achieved in 74.6% of patients treated with MOPP (44 of 59) and in 90.5% of those given ADM-Reg (57 of 63). No difference was observed in the incidence of complete remission with regard to the type of ADM-Reg utilized [MABOP (mechlorethamine, doxorubicin, bleomycin, vincristine, and prednisone), 92.9%; ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine), 95.6%; and MOPP alternated with ABVD, 84.6%]. The superiority of ADM-Reg versus MOPP was also confirmed in the 7-year analysis of freedom from disease progression (73.2% vs 42.2%), relapse-free survival (81.2% vs 54.3%), and overall survival (80.5% vs 44.4%). Thrombocytopenia was less frequently observed with ADM-Reg (30%), particularly following ABVD (13%), compared to MOPP (73%). The lowest incidence of alopecia occurred in patients given MOPP (15%) or MOPP/ABVD (19%). Acute nonlymphoblastic leukemia was observed in patients treated with MOPP (five of 59) and MABOP (one of 14). The observed findings indicate that in patients failing to respond to primary radiotherapy, salvage regimens containing doxorubicin are more effective than MOPP. Furthermore, combinations devoid of procarbazine and alkylating agents (ABVD) or with less intensive administration of these drugs (MOPP/ABVD) were not associated with secondary leukemia.     

Results of a prospective randomized clinical trial of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) followed by radiation therapy (RT) versus ABVD alone for stages I, II, and IIIA nonbulky Hodgkin disease

To determine whether combined modality therapy (CMT) is superior to chemotherapy (CT) alone, 152 untreated Hodgkin disease patients with clinical stages (CSs) IA, IB, IIA, IIB, and IIIA without bulk disease were prospectively randomized to 6 cycles of doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD) alone or 6 cycles of ABVD followed by radiation therapy (RT) (3600 cGy: involved field for 11 patients, modified extended field for the rest). Of 76 patients randomized to receive RT, 65 actually received it, and 11 did not (4 progressed, 1 had bleomycin toxicity, 6 refused). For ABVD + RT, the complete remission (CR) percentage was 94% and no major response, 6%. For ABVD alone, 94% achieved a CR; 1.5%, a partial response (PR); and 4.5%, no major response. At 60 months CR duration, freedom from progression (FFP), and overall survival (OS) for ABVD + RT versus ABVD alone are 91% versus 87% (P = .61), 86% versus 81% (P = .61), and 97% versus 90% (P = .08), respectively (log-rank). The 95% confidence intervals for CR duration, FFP, and OS differences at 5 years were -8% to 15%, -8% to 18%, and -4% to 12%, respectively. Although significant differences were not seen, it is possible that a benefit in outcome of less than 20% for CMT might be seen in a larger trial.     

Clinical features and outcomes of Hodgkin’s lymphoma in Korea: Consortium for Improving Survival of Lymphoma (CISL)

Ethnic and regional differences in the epidemiology and pathological aspects of Hodgkin's lymphoma (HL) between Western and Asian patients may be associated with differences in clinical features and prognosis. We retrospectively analyzed the clinical and histopathological characteristics, therapeutic outcomes, and prognostic factors of 539 HL patients treated at 16 centers in Korea. We found that the incidence of histological subtypes of HL in Korea was similar to that in Western and other Asian countries. However, the incidence peaked between 16 and 30?years of age, unlike the bimodal age distribution seen in Western countries. In patients with stage I-IIA non-bulky disease, the complete response (CR) rate was similar between combined modality therapy and chemotherapy alone (93% vs. 84%, P?=?0.44), and there was no difference in relapse-free survival (RFS) and overall survival (OS). Patients with stage I-II disease plus unfavorable factors and those with advanced-stage disease treated with combination chemotherapy regimens had an overall CR rate of 77%, with no difference between doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) and non-ABVD regimens (77.2% vs. 76.8%, P?=?0.95). Among those patients who achieved final CR, there was no significant difference in RFS or OS between those who achieved interim CR and PR. Only the presence of B symptoms was independently predictive of a shorter RFS. Age?>?45?years, Eastern Cooperative Oncology Group 2-4, and B symptoms were independent risk factors for death. Although the incidence of HL was lower in Korea than in Western countries, the distribution of morphological subtypes, treatment outcomes, and patient prognosis were similar.     

Advanced stage and unfavorable Hodgkin's disease in the Chinese-a 20-year experience.

We retrospectively analyzed 57 patients with advanced stage (stage III/IV) or unfavorable (presence of B symptoms or bulky disease) Hodgkin's disease from January 1977 to December 1997. There were 29 male and 28 female patients. The median age was 27 years old (range, 13-59). Lactate dehydrogenase levels ranged from 104 units/l to 2320 units/l (median, 433). Eighteen (31.6%), 13 (22.8%), and 26 (45.6%) patients had stage II bulky, stage III, and stage IV disease, respectively. Twenty-five (44%) patients had B symptoms. One (1.8%), 3 (5.3%), 36 (63.2%), and 17 (29.8%) had lymphocyte predominant, lymphocyte depleted, nodular sclerosis, and mixed cellularity histology, respectively. Chemotherapy regimens included mechlorethamine, vincristine, procarbazine, prednisone (MOPP) (n = 9), adriamycin, bleomycin, vinblastine, dacarbazine (ABVD) (n = 23), MOPP alternating with ABVD (n = 13), and COPP-ABV hybrid (n = 12). Complete remission was achieved in 47 (82.4%) patients. Eleven patients (23%) relapsed after the first complete remission and four (36%) attained a second complete remission with salvage chemotherapy. Projected overall survival was 69.0% at 10 years and 20 years. Disease-free survival rates were 71% at 10 years and 20 years. Of the potential prognostic factors analyzed (age, sex, stage, lactate dehydrogenase, serum albumin level, regimen, B symptoms and bulky disease) by using the Cox regression model, only a low albumin level was found to adversely affect overall survival (P = 0.003). In conclusion, despite the relative low incidence of Hodgkin's disease in Hong Kong Chinese, the treatment outcomes in patients with advanced stage or unfavorable Hodgkin's disease is comparable to Caucasian patients.     

Cyclic delivery of MOPP and ABVD combinations in Stage IV Hodgkin's disease: rationale, background studies, and recent results

This paper summarizes the experience achieved at the Cancer Institute of Milan with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy in various stages of Hodgkin's disease, with special emphasis on the cyclic delivery of mechlorethamine, vincristine, prednisone, and procarbazine (MOPP) and ABVD in the primary treatment of stage IV disease. Six cycles of ABVD yielded a complete remission (CR) rate (71%) similar to that of MOPP (63%). ABVD combined with radiotherapy in 153 patients with stage IIB, IIIA, or IIIB disease was superior to MOPP plus radiotherapy in the CR induction (94% vs 79%, P less than 0.01), particularly in the presence of nodular sclerosis histology (P less than 0.03) and B symptoms (P = 0.01), as well as in the relapse-free survival of patients with pathologic stage IIIA disease (ABVD, 100%; MOPP, 68%; P = 0.02). Total survival was similar between the two treatment groups, but, compared to MOPP, ABVD chemotherapy was associated with a lower incidence of delayed toxic effects such as azoospermia, prolonged amenorrhea, and cancerigenesis. ABVD induced CR in 59% of 54 patients resistant to MOPP; 37.5% of the complete responders remain alive and disease-free at 5 years. The cyclic delivery of MOPP and ABVD was significantly superior to that of MOPP alone in terms of CR (92% vs 71%; P = 0.02), freedom from disease progression (70% vs 37%; P less than 0.0001), and relapse-free survival (77% vs 47%; P less than 0.01) at 5 years. Toxic effects were similar between the two treatment groups, but there was a higher incidence of vomiting and alopecia following ABVD chemotherapy; in the group given MOPP alone, one patient who had previously failed extensive irradiation developed acute nonlymphocytic leukemia. ABVD is confirmed to be an effective regimen that is non-cross-resistant to MOPP and devoid of late morbidity. Therefore, its administration, when alternated monthly with MOPP, offers the possibility to improve the cure rate of Hodgkin's disease.     

Long-term results of 60 patients with pathologic stage I & IIA Hodgkin's disease treated with exclusive mantle radiation therapy.

Between January 1972 and December 1982 60 patients with pathological stage IA and IIA Hodgkin's disease (HD) were submitted to Mantle irradiation only. Twenty-five were in stage I (32.1%) and 35 in stage II (67.9%). All patients were submitted to staging laparotomy. Cases with large mediastinal mass were excluded from this series. Delivered doses were 44 Gy in involved areas, 40 Gy on the mediastinum and 36 Gy on uninvolved sites. Twenty-four patients in stage I (96%) and 33 in stage II (94.2%) obtained complete remission. Actuarial 10- and 20-yr overall (OS) rates were 86% and 79.1%, respectively. Event-free (EFS) and relapse-free (RFS) survival rates at 10 and 20 yr were 67.5% and 62.1%, respectively. The occurrence of disease relapse resulted in the only statistical significant prognostic factor for OS in both univariate and multivariate analysis. Distant and extranodal recurrences were significantly (P<0.01) related to a reduced OS. On multivariate analysis stage was the only determinant factor for increased RFS. Extended field RT proved to be an effective curative modality for stage I HD patients, whereas 15 out of 33 patients in stage II relapsed requiring salvage therapy. Long-term analysis of survival and treatment-related morbidity rates will improve our knowledge and assist the physicians to choose the therapeutic option to offer to HD patients.     

Early‐stage Hodgkin lymphoma outcomes after combined modality therapy according to the post‐chemotherapy 5‐point score: can residual pet‐positive disease be cured with radiotherapy alone?

Early‐stage classical Hodgkin lymphoma (HL) patients are evaluated by an end‐of‐chemotherapy positron emission tomography‐computed tomography (eoc‐PET‐CT) after doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) and before radiation therapy (RT). We determined freedom from progression (FFP) in patients treated with ABVD and RT according to the eoc‐PET‐CT 5‐point score (5PS). Secondarily, we assessed whether patients with a positive eoc‐PET‐CT (5PS of 4–5) can be cured with RT alone. The cohort comprised 174 patients treated for stage I‐II HL with ABVD and RT alone. ABVD was given with a median of four cycles and RT with a median dose of 30·6 Gy. Five‐year FFP was 97%. Five‐year FFP was 100% (0 relapses/98 patients) for patients with a 5PS of 1–2, 97% (2/65) for a 5PS of 3, 83% (1/8) for a 5PS of 4, and 67% (1/3) for a 5PS of 5 (P < 0·001). Patients with positive eoc‐PET‐CT scans who were selected for salvage RT alone had experienced a very good partial response to ABVD. Risk factors for recurrence in this subgroup included a small reduction in tumour size and a ‘bounce’ in ≥1 PET‐CT parameter (reduction then rise from interim to final scan). Thus, a positive eoc‐PET‐CT is associated with inferior FFP; however, appropriately selected patients can be cured with RT alone.     

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相似文献   

Alternating non-cross-resistant combination chemotherapy or MOPP in stage IV Hodgkin's disease. A report of 8-year results

In patients with stage IV Hodgkin's disease mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) was randomly tested against MOPP alternated monthly with doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD). All 88 evaluable patients had not received chemotherapy and 25 had had a relapse after primary irradiation. The complete remission rate with MOPP/ABVD was 88.9% (40 of 45 patients), and with MOPP, 74.4% (32 of 43 patients). The 8-year results show that MOPP/ABVD was superior to MOPP in terms of freedom from progression (64.6% compared to 35.9%; p less than 0.005), relapse-free survival (72.6% compared to 45.1%; p less than 0.01), total survival (83.9% compared to 63.9%; p less than 0.06), and survival of complete responders (94.8% compared to 77.1%; p = 0.04). The delivery of MOPP/ABVD was not associated with an increased incidence of major toxicity. The early sequential rotation of two equally effective and non-cross-resistant drug combinations can substantially improve the likelihood of cure in patients with Hodgkin's disease.     

Modification of initial therapy in early and advanced Hodgkin lymphoma,based on interim PET/CT is beneficial: a prospective multicentre trial of 355 patients

This multicentre study evaluated 5‐year progression‐free (PFS) and overall survival (OS) in early and advanced Hodgkin lymphoma (HL), where therapy was individualized based on initial prognostic factors and positron emission tomography‐computed tomography performed after two cycles (PET‐2). Between September 2006 and August 2013, 359 patients aged 18–60 years, were recruited in nine Israeli centres. Early‐HL patients initially received ABVD (adriamycin, bleomycin, vinblastine, dacarbazine) ×2. Depending on initial unfavourable prognostic features, PET‐2‐positive patients received additional ABVD followed by involved‐site radiotherapy (ISRT). Patients with negative PET‐2 and favourable disease received ISRT or ABVD ×2; those with unfavourable disease received ABVD ×2 with ISRT or, alternatively, ABVD ×4. Advanced‐HL patients initially received ABVD ×2 or escalated BEACOPP (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, prednisone; EB) ×2 based on their international prognostic score (≤2 or ≥3). PET‐2‐negative patients further received ABVD ×4; PET‐2‐positive patients received EB ×4 and ISRT to residual masses. With a median follow‐up of 55 (13–119) months, 5‐year PFS was 91% and 69% for PET‐2‐negative and positive early‐HL, respectively; 5‐year OS was 100% and 95%, respectively. For advanced‐HL, the PFS was 81% and 68%, respectively (P = 0·08); 5‐year OS was 98% and 91%, respectively. PET‐2 positivity is associated with inferior prognosis in early‐HL, even with additional ABVD and ISRT. Advanced‐HL patients benefit from therapy escalation following positive PET‐2. EB can be safely de‐escalated to ABVD in PET‐2‐negative patients.     

Stage I-III Hodgkin's Disease: Outcome and Pattern of Failure Following Treatment with Radiation Therapy and Chemotherapy in a Modern Era

Purpose: To analyse the long term outcome, pattern of failure and treatment related complications after radiation therapy (RT) with or without chemotherapy for stage I—III Hodgkin's disease (HD).

Material and methods: Detailed records from 86 patients with stage I—III HD treated between 1989 and 1998, were retrospectively reviewed. Seventeen patients with favourable stage I-IIA were treated with RT alone, and the remaining 69 patients with combined modality treatment (CMT). Patients treated with RT received extended-field or subtotal nodal irradiation (STNI) to a total dose of 36–54 Gy, and patients with CMT, received involved-field irradiation to a lower doses, 26–40 Gy. The median follow-up time was 50 months (range 16–180).

Results: The 10-year overall survival (OS) for the whole group was 96% (SE 2%), 100% for stage I, 95% for stage II and 100% for stage III patients. Of potential prognostic factors analysed for statistical significance, only the response to chemotherapy (p = 0.0393) was found to influence significantly OS rates. Twelve patients (13.9%) relapsed. Salvage treatment was effective in 10 of the 12 relapsed patients. The 10-year freedom from treatment failure (FFTF) was 79% (SE 6%). Although 8 (9.6%) of the 83 surviving patients developed late effects that could represent toxicity from the treatment, no patient died of late complications.

Conclusions: RT alone for favourable early stage HD attains good survival rates with a modest treatment related morbidity. For patients with unfavourable stage II and stage III HD, CMT with limited RT provides a good to excellent prognosis.     

MANTLE IRRADIATION FOR STAGE I AND STAGE II HODGKIN'S DISEASE – RESULTS OF A 10 YEAR EXPERIENCE

Abstract: One hundred and thirty patients with Stage I and II supradiagphragmatic Hodgkin's disease treated with mantle irradiation alone at the Peter MacCallum Hospital, Melbourne between 1968–1977 were analysed retrospectively. The median followup was 7.4 years with a minimum of three years.
There were 64 clinically staged (CS) and 66 pathologically staged (PS) patients. The major difference between the two groups was the transdiaphragmatic relapse which occurred in 33% of CS patients, and 7.5% in PS patients. The actuarial five year relapse free survival (RFS) was 48% for CS patients and 67% for PS patients, but the five year overall survival was 90% for both groups, reflecting the impact of salvage treatment.
Avid attention must be given to radiotherapy techniques to minimise local treatment failures. High grade nodular sclerosis Hodgkin's disease is associated with poor RFS even after adjustment has been made for stage and constitutional symptoms (p < 0.003). Further studies will be made on this group of patients who may benefit from combined modality treatment. For PS I and II patients mantle irradiation gives a five year RFS of 67%, thus offering potential for cure in these patients.     

Treating limited-stage nodular lymphocyte predominant Hodgkin lymphoma similarly to classical Hodgkin lymphoma with ABVD may improve outcome

The appropriate therapy for limited-stage nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is unclear. In contrast to classical Hodgkin lymphoma (CHL), chemotherapy is often omitted; however, it is unknown whether this impacts the risk of relapse. Herein, we compared the outcome of patients with limited-stage NLPHL treated in an era in which ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) chemotherapy was routinely incorporated into the primary therapy to an earlier era in which radiotherapy (RT) was used as a single modality. Using the British Columbia Cancer Agency Lymphoid Cancer Database, 88 patients with limited-stage NLPHL (stage 1A/1B or 2A, nonbulky disease < 10 cm) were identified. Treatment followed era-specific guidelines: before 1993, (n = 32) RT alone; and 1993 to present (n = 56), ABVD-like chemotherapy for 2 cycles followed by RT with the exception of 14 patients who received ABVD chemotherapy alone. Most patients were male (75%) with stage I disease (61%). In an era-to-era comparison, the 10-year time to progression (98% vs 76% P = .0074), progression-free survival (91% vs 65% P = .0024), and OS (93% vs 84%, P = .074) favored the ABVD treatment era compared with the RT alone era. Treating limited-stage NLPHL similarly to CHL may improve outcome compared with the use of radiation alone.     

Autologous bone marrow transplantation as adjuvant treatment for high-risk Hodgkin's disease in first complete remission after MOPP/ABVD protocol.

Fifteen patients with very poor prognosis Hodgkin's disease in remission after MOPP/ABVD regimen, were treated with high-dose chemotherapy (HDC) and autologous marrow transplantation (ABMT) immediately after achieving complete remission (CR). Thirteen patients (86.6%) remain alive in unmaintained CR at a median time of 36 months (range 10-64 months) post-transplant. In the other two patients reasons for failure included relapse of Hodgkin's disease (one patient) and death due to interstitial pneumonitis secondary to carmustine therapy. These patients were compared with a historical control group consisting of 24 patients with the same poor prognostic factors, who achieved CR with MOPP/ABVD and did not receive other treatment. Eight out of 24 patients (33%) remain alive and well in unmaintained CR at a median time of 42 months (range 19-83 months). The administration of MOPP/ABVD combined with HDC and ABMT was not associated with an increased incidence of major toxicity. The results achieved support the early sequential treatment of a highly effective drug combination followed by HDC/ABMT that can substantially improve the likelihood of cure in these advanced stage very poor prognosis Hodgkin's disease patients.     

Evaluation of cytoreductive therapy prior to high dose treatment with autologous bone marrow transplantation in relapsed and refractory Hodgkin's disease

Based on observations that bulky disease at autologous bone marrow transplantation (ABMT) may be correlated with poor outcome in Hodgkin's disease, we have assessed the ability of conventional-dose chemoradiotherapy to reduce tumour burden to a minimum prior to ABMT. Thirty-seven patients with relapsed or refractory Hodgkin's disease referred for intensive therapy and ABMT were treated initially with one to five cycles of DHAP chemotherapy. All patients had previously received MOPP and ABVD chemotherapy or similar regimens. Four patients achieved complete remission (CR) and 12 partial remission (PR), for a total response rate of 43%. Eight partial responders and four non-responders to DHAP achieved significant further tumour reduction with local radiotherapy (five CR, seven PR). Six of 10 non-responders to DHAP responded to alternative salvage chemotherapy (mini-BEAM, CEP or augmented CVP). Overall, 24/37 patients (65%) achieved effective cytoreduction (nine CR, 15 PR with minimal disease) and have proceeded to ABMT. Patients with bulky disease at relapse or limited stage (II, IIIA) at diagnosis were less likely to respond to DHAP, but some of these could be cytoreduced with alternative therapy. In addition, the number of prior chemotherapy regimens correlated inversely with likelihood of response to DHAP. The results indicate that approximately two-thirds of patients with Hodgkin's disease who relapse after MOPP and ABVD-like regimens can achieve effective cytoreduction with conventional-dose chemoradiotherapy and proceed to ABMT in CR or PR with minimal disease.     

Critical value of laparotomy with splenectomy in stage III Hodgkin's disease as restaging procedure after chemotherapy

38 patients with stage III Hodgkin's disease underwent laparotomy with splenectomy as restaging procedure after first line chemotherapy which included MOPP, ABVD, or both. 28 patients were judged to be in clinical complete remission (CR) and 10 were resistant or had relapsed. Among patients in CR, 27 (96%) were confirmed to be in pathological CR; among patients resistant or relapsed, 9 (90%) were confirmed to have disease in the abdomen or retroperitoneum. The therapy for patients in clinical remission before laparotomy consisted of TNI or sTNI in 19 patients, mediastinal radiation in 6 patients and no further therapy in the remaining 3 patients. No significant differences were seen in survival and relapse-free survival between those patients treated by extensive and those treated by local radiotherapy or no further therapy. Instead, among those patients who received extensive radiotherapy 3 developed acute non-lymphoid leukemia (ANLL). The therapy for this group of patients consisted of further chemotherapy in 7 who had concomitant liver involvement and TNI in the remaining 3 who had the disease confined to the spleen and/or lymph nodes. Among these patients, only 3 obtained CR; 2 with radiation and 1 who was resistant to MOPP, with ABVD. This study leads us to re-consider the role of laparotomy in stage III HD which should be used as non-routine procedure only in selected patients without poor prognostic factors who may be cured by radiotherapy alone. In patients resistant to chemotherapy, an early evaluation of disease in the abdomen may be useful for a better salvage treatment.
