Prevalence of HCV infection in nongastric marginal zone B-cell lymphoma of MALT.

BACKGROUND: Hepatitis C virus (HCV) infection is frequently associated with B-cell non-Hodgkin's lymphomas. We investigated the prevalence of HCV infection in nongastric marginal zone lymphomas of mucosa-associated lymphoid tissue (MALT) in order to define the relationship between the viral infection and the presenting features, treatment, and outcome. METHODS: We retrospectively studied 172 patients with a histological diagnosis of marginal zone B-cell lymphoma of MALT, except for stomach, and with available HCV serology, among a series of 208 patients. RESULTS: HCV infection was documented in 60 patients (35%). Most HCV-positive patients (97%) showed a single MALT organ involvement. HCV-positive patients showed a more frequent involvement of skin (35%), salivary glands (25%), and orbit (15%). The majority of stage IV HCV-positive patients (71%) had a single MALT site with bone marrow involvement. The overall response rate was similar in HCV-positive (93%) and HCV-negative patients (87%). Overall survival (OS) and event-free survival (EFS) did not differ according to HCV infection. In multivariate analysis, advanced disease (stage III-IV) was associated with a poorer OS (P = 0.0001), irrespective of HCV serostatus. CONCLUSIONS: This study shows that nongastric marginal zone lymphomas are characterized by a high prevalence of HCV infection. Patients with involvement of a single MALT site have the highest prevalence of HCV. HCV-positive nongastric lymphomas of MALT show an indolent course similar to HCV-negative patients and seem an ideal target for exploiting the antilymphoma activity of antiviral treatments.

Distinctive natural history in hepatitis C virus positive diffuse large B-cell lymphoma: analysis of 156 patients from northern Italy.

BACKGROUND: Diffuse large B-cell lymphoma (DLBCL) has been correlated to hepatitis C virus (HCV) infection in few series, but characteristics and outcome of these patients remain undefined. PATIENTS AND METHODS: We analyzed 156 previously untreated consecutive HCV-positive patients with DLBCL observed between 1994 and 2004 in three major institutions from northern Italy. RESULTS: Median age at presentation was 63 years and 8% of patients had DLBCL transformed from low-grade lymphomas. Spleen was the most frequently involved extranodal site, followed by liver and stomach. Treatment was delivered with cure-intent in 132 patients, while the remaining 24 patients received monochemotherapy or radiotherapy alone due to old age or seriously impaired hepatic function. Only five patients (4%) had to discontinue chemotherapy due to severe liver function impairment. The addition of rituximab did not seem to affect patients' tolerance to treatment. Five-year overall survival of the entire cohort was 72%, while 5-year progression-free survival (PFS) of the 132 patients treated with cure-intent was 51%. Hepatitis B virus co-infection, advanced Ann Arbor stage and nodal origin of the tumor resulted the strongest adverse prognostic factors. CONCLUSIONS: Patients with HCV-positive DLBCL share distinctive clinical features. Future studies should prospectively evaluate the association between HCV and aggressive lymphomas.

A model of in vivo purging with Rituximab and high-dose AraC in follicular and mantle cell lymphoma.

We studied a model of in vivo purging with Rituximab and high-dose (HD) cytarabine in 14 patients with relapsed/refractory follicular lymphoma and two with refractory mantle cell lymphoma enrolled in a program of HD chemotherapy and autotransplant. After two courses of debulking immunochemotherapy with Rituximab, Vincristine and Cyclophosphamide, we used a combination of Rituximab, HD cytarabine and granulocyte colony-stimulating factor for peripheral blood stem cells (PBSC) mobilization. The median number of CD34+ cells collected was 14.69 x 10(6)/kg (range 5.74-73.2). Monitoring of peripheral CD19+ and CD20+ B cells prior to and throughout the purging period showed that a treatment with Rituximab, Vincristine and Cyclophosphamide results in a profound depletion of B cells in peripheral blood. B-cell depletion persists during mobilization with Rituximab and HD cytarabine allowing a collection of PBSC free of B cells (median CD19+ and CD20+ cells counts 0%). Of nine patients PCR positive for bcl-2 or bcl-1 in blood and marrow at the start of immunochemotherapy, all showed PCR-negative PBSC. In conclusion, in patients with indolent lymphoma, the concurrent administration of Rituximab and HD cytarabine is a safe and efficient method to obtain in vivo purged PBSC. Immunochemotherapy prior to mobilization produces B-cell depletion and seems to be a useful preparative step.

Acute myeloid leukemia (AML) having evolved from essential thrombocythemia (ET): distinctive chromosome abnormalities in patients treated with pipobroman or hydroxyurea.

ET is a chronic myeloproliferative disorder rarely evolving into AML, sometimes preceded by a myelodysplastic syndrome (MDS). Such transformations mostly occur in patients treated with radiophosphorous ((32)P) or alkylating agents, especially busulfan. Recently, concern has also arisen about the long-term safety of hydroxyurea (HU). Pipobroman (PI), a well tolerated and simple to use drug, constitutes a valid alternative to those cytoreductive treatments. The present study reports on 155 ET patients treated at our institution from 1985 to 1995, and monitored until December 2000. A good control of thrombocytosis was achieved with PI as the only treatment in 106 patients and with HU in 23 patients. Twenty-six patients received no treatment. After a median follow-up of 104 months, seven patients (four treated with HU, and three with PI) developed AML whereas one patient treated with PI developed MDS. A significant difference in progression-free survival was observed between HU- and PI-treated patients (P = 0.004). A short-arm deletion of chromosome 17 was most frequently detected in HU-treated patients, while a long-arm trisomy of chromosome 1 and a monosomy 7q were seen in PI-treated patients. No TP53 mutation was discovered in the six patients studied (two HU-treated and four PI-treated). We conclude that these cytogenetic abnormalities are not linked to the natural history of the disease, but rather that they might be induced by the cytoreductive treatment.

A sequence of immuno-chemotherapy with Rituximab, mobilization of in vivo purged stem cells, high-dose chemotherapy and autotransplant is an effective and non-toxic treatment for advanced follicular and mantle cell lymphoma.

Options for relapsed/refractory indolent lymphoma include chemotherapy, immunotherapy and high-dose therapy with autologous support. The best combination of these approaches, however, is not defined. We treated 10 patients with relapsed/refractory follicular (n = 7) or mantle cell lymphoma (n = 3) using chemotherapy, immunotherapy, high-dose therapy and autotransplant in a sequence of four phases, each designed to play a specific role in tumour eradication. After the debulking with VACOP-B (doxorubicin, cyclophosphamide, etoposide, vincristine, prednisone, bleomycin) (phase 1), 9/10 patients responded but none achieved a molecular response. After the immuno-chemotherapy phase, which combined Rituximab with vincristine and cyclophosphamide, seven patients were in complete response (CR) and three in good partial response (PR), and all those with a molecular marker of disease showed a disappearance of the signal from marrow and blood. Phase 3, which coupled high-dose cytarabine with Rituximab, was effective in mobilizing an adequate number of progenitor cells that were polymerase chain reaction negative in all informative cases. Phase 4 consisted of high-dose therapy with autologous support followed by two doses of Rituximab. Autograft was performed in nine patients. The haematopoietic recovery was as expected. This sequence of chemotherapy, immuno-chemotherapy, stem cell mobilization with in vivo purging and autotransplant, organized in four blocks of treatment, was simple to administer and devoid of toxic effects. It permits rapid attainment of clinical and molecular response and enables the harvest of lymphoma-free peripheral blood progenitor cells even in heavily pretreated patients with relapsed or refractory disease.

Efficacy of pipobroman in the treatment of polycythemia vera: long-term results in 163 patients.

BACKGROUND AND OBJECTIVES: Polycythemia vera (PV) is a myeloproliferative disorder, characterized by the expansion of the red cell mass. Our purpose was to evaluate the efficacy of pipobroman (PB) in the long-term control of PV and to assess early and late events. DESIGN AND METHODS: From June 1975 to December 1997, 163 untreated patients with PV (median age 57 years, range 30-82) were treated with PB in a single Institute for a median follow-up of 120 months. The diagnosis was made according to the Polycythemia Vera Study Group criteria. PB was given at the dose of 1 mg/kg/day until hematologic response (hematocrit < 45% and platelets < 400x109/L) and of 0.3-0.6 mg/kg/day as maintenance therapy. RESULTS: Hematologic remission was achieved in 94% of patients in a median time of 13 weeks (range 6-48). Median overall survival was 215 months, with a standardized mortality ratio of 1.7. The cumulative risk of death was 11%, 22%, and 26% at 7, 10, and 12 years, respectively. The incidence of thrombotic events was 18.4x105 person-year and the cumulative risk was 6%, 11%, 16%, and 20% at 3, 7, 10, and 12 years respectively. Acute leukemia occurred in 11 patients, myelofibrosis in 7, and solid tumors in 11. The 10-year cumulative risk of leukemia, myelofibrosis, and solid tumors was 5%, 4%, and 8%, respectively. In the logistic analysis age over 65 (p = 0.0001) and thrombotic events at diagnosis (p = 0.001) were significantly correlated with a higher risk of death. Female gender (p = 0.02) and age over 65 (p = 0.01) significantly influenced the occurrence of thrombotic complications. Age was the only significant risk factor for leukemia (p = 0.04) and for solid tumors (p = 0.03), while the duration of PB treatment did not influence these risks. No significant risk factor was demonstrated for myelofibrosis. INTERPRETATION AND CONCLUSIONS: This study demonstrates in a large series of patients, observed for a long period, that pipobroman is effective in the long-term control of PV. The risk of early thrombotic complications at 3 years is 6% and the 10-year risk of acute leukemia, late myelofibrosis, and solid tumors is 5%, 4%, and 8%, respectively. The duration of pipobroman treatment did not correlate with these events.

Treatment of early-stage Hodgkin's disease with four cycles of ABVD followed by adjuvant radio-therapy: analysis of efficacy and long-term toxicity.

BACKGROUND AND OBJECTIVES: The use of combined modality therapy in early-stage Hodgkin's disease can spare staging laparotomy and reduces the risk of relapse compared to radiation alone. This paper reports on the efficacy and long-term events of a combined modality approach consisting of a brief course of chemotherapy followed by adjuvant radiotherapy, without laparotomy, in early-stage Hodgkin's disease. DESIGN AND METHODS: This study included 78 patients with Hodgkin's disease (20 in stage I and 58 in stage II); 60% had mediastinal enlargement (12% had bulky disease) and 5% had subdiaphragmatic disease. Their median age was 33 years (range: 15-64) and median follow-up 60 months. The treatment program consisted of four cycles of ABVD followed by adjuvant radiation to involved sites (43 patients) or involved and contiguous sites of disease (35 patients); radiation doses ranged from 30 to 36 Gy to uninvolved and involved sites, respectively; bulky disease received up to 44 Gy. Gonadal function in women was assessed by hormonal tests and evaluation of menses; young men were given the opportunity to have their semen cryopreserved. RESULTS: The treatment program was completed in a median of 6.2 months (range: 5-10). The complete remission rate was 88% after 4 courses of ABVD and 98.7% after adjunctive RT. The 5-year relapse-free survival was 97% and overall survival 98%; three patients died, one of disease progression and two of small cell lung carcinoma. Long-term events included three cases of pulmonary fibrosis with symptomatic interstitial disease, one case of dilated cardiomyopathy with cardiac failure (all had received mediastinal radiation) and four cases of dysthyroidism. Fertility was preserved in young women, with three subsequent normal pregnancies. Second neoplasms included two small cell lung carcinomas and one breast carcinoma. INTERPRETATION AND CONCLUSIONS: In early-stage Hodgkin's disease, four cycles of ABVD followed by adjuvant radiotherapy produced a 5-year overall survival of 98%. Prolonged monitoring for therapy-related long term complications is mandatory in these potentially curable patients.

Fludarabine, cyclophosphamide, and dexamethasone (FluCyD) combination is effective in pretreated low-grade non-Hodgkin's lymphoma.

PURPOSE: Fludarabine phosphate is effective as a single agent in low-grade non-Hodgkin's lymphoma (NHL). Combined with other antineoplastic agents it enhances the antitumor effect. Our aim was to define the therapeutic efficacy and toxicity of a combination of fludarabine, cyclophosphamide and dexamethasone (FluCyD) in patients with advanced low-grade lymphoma. PATIENTS AND METHODS: Twenty-five adults with pretreated advanced-stage low-grade NHL were treated with three-day courses of fludarabine 25 mg/m2/day, cyclophosphamide 350 mg/m2/day, and dexamethasone 20 mg/day, every four weeks for a maximum of six courses. RESULTS: Of the 25 patients, 18 (72%) responded, 8 (32%) achieving CR and 10 (40%) PR. Seven were failures. The median follow-up was 21 months (5-26). Eight CR patients remain in CR after 5-21 months. Of 10 PR patients, 3 are in continuous PR without further treatment after 12, 17 and 18 months. Myelosuppression was the most prevalent toxic effect. Although severe granulocytopenia (granulocyte count nadir < 500/microliter) and thrombocytopenia (platelet count nadir < 50,000/microliter) occurred in only 10% and 16% of courses, respectively, slow granulocyte or platelet count recovery caused delay of 40% of the courses. Nine patients (36%) required discontinuation of therapy because of persistent granulocytopenia and/or thrombocytopenia: three after one course, three after 2-4 courses, and three after five courses. Thirteen infectious episodes in 11 patients complicated 11% of courses. Two of 10 patients monitored for the circulating EBV load showed increased viral load. One of these developed aggressive lymphoma. CD4+ lymphocytes declined from a pre-therapy median value of 425/microliter to 141/microliter post-treatment (P = 0.001). Non-hematologic toxicities were rare and mild. CONCLUSIONS: The combination of fludarabine with cyclophosphamide and dexamethasone is effective in pretreated advanced-stage low-grade NHL. It may broaden the range of therapeutic options in the salvage treatment of these patients. The main toxicity of this combination is prolonged myelosuppression that may cause treatment delay or withdrawal. The benefit of adding granulocyte colony-stimulating factor, particularly in patients with poor marrow reserve, needs to be investigated.

Serum CA 125 is of clinical value in the staging and follow-up of patients with non-Hodgkin's lymphoma: correlation with tumor parameters and disease activity.

BACKGROUND: CA 125 is a glycoprotein produced by epithelial ovarian tumors and by mesothelial cells; its levels also have been shown to be elevated in patients with non-Hodgkin's lymphoma (NHL). METHODS: The authors evaluated serum CA 125 levels in patients with NHL to elucidate the frequency of this finding, its relationship with other presenting features, and its potential role as tumor marker. One hundred and fifty-seven patients underwent the first CA 125 assessment at onset, 54 at disease recurrence or progression, and 62 during complete remission (CR). RESULTS: Of the 157 patients evaluated at diagnosis (median CA 125: 26 U/mL; range, 2-1400 U/mL), 63 (40%) had increased CA 125 values. Higher CA 125 levels were associated with advanced disease, aggressive histology, mediastinal and/or abdominal involvement, bulky tumor, high tumor burden, effusions, contiguous extranodal extension, high serum lactate dehydrogenase (LDH) activity, and elevated beta2-microglobulin (beta2-M) levels. Parameters identified by multivariate analysis to be independently associated with high CA 125 were: aggressive histology, mediastinal and/or abdominal disease, bulky tumor, high serum LDH activity and beta2-M serum levels, and the presence of effusion (P = 0.0000; explained variation = 0.64). Of the patients presenting with abnormal CA 125 levels, all those who achieved a CR (35) and 3 of the 6 who achieved a partial response had normalization of CA 125 values by the end of treatment. Conversely, CA 125 remained above normal values in 18 nonresponders. All 62 patients evaluated during CR showed normal CA 125 levels. Among patients first evaluated at disease recurrence or progression, 22 of 54 (41%) showed increased CA 125 levels, which were associated with the same parameters of disease found in patients examined at diagnosis. CONCLUSIONS: High serum CA 125 levels were found to correlate with mediastinal and/or abdominal involvement, high tumor mass, and effusions, reflecting the reaction of mesothelial cells to the tumor. Serum CA 125 is a reliable biologic marker for the staging and restaging of patients with lymphoma. Serial measurements are useful, in conjunction with other markers, for monitoring response to treatment.

Randomized clinical study comparing aggressive chemotherapy with or without G-CSF support for high-risk myelodysplastic syndromes or secondary acute myeloid leukaemia evolving from MDS.

One hundred and five consecutive primary high-risk myelodysplastic syndromes (MDS) or secondary acute myeloid leukaemia (sAML) evolving from MDS (performance status 0-3, ECOG) entered this study. Induction chemotherapy (CT) consisted of idarubicine 12 mg/m2 i.v. on days 1 and 2, etoposide 60 mg/m2/12h i.v. for 5d, Ara-C 120 mg/ m2/12h i.v. for 5d (one or two courses). Patients were randomized to receive or not G-CSF (5 microg/kg/d subcutaneously 48 h after the end of CT). 52 cases underwent CT alone and 53 CT+G-CSF. The CT+ G-CSF patients had a significantly shorter duration of neutropenia (8 nu 16d) with a lower incidence of infections and significantly better responses (CR+PR: 74% v 52%, P<0.05). 40 patients entered CR: 17 with CT and 2 3 with CT+G-CSF. Responders underwent two consolidation courses with the same CT, followed by high-dose Ara-C (2 g/m2 every 12h for 3 d). Most CRs were clonal. At present 21 responders have relapsed (median relapse-free survival 4 5 months). Eight responders received an allo-BMT, six are alive in CR 7-57 months post-transplant. Therefore allo-BMT only increases the chance of a long survival and possible cure. In conclusion, CT+G-CSF did not prolong either CR duration or survival; the growth factor support, however, increased the number of allo-transplantable cases by inducing higher remission rates and improving clinical conditions.

Efficacy of a combination of idarubicin, etoposide and intermediate-dose cytosine arabinoside as salvage therapy in relapsing or resistant unfavorable lymphoma.

BACKGROUND AND OBJECTIVE: Idarubicin, an anthracycline analogue, is active in non-Hodgkin's lymphoma. This study evaluates the efficacy and toxicity of a combination of idarubicin, etoposide and intermediate-dose cytarabine (IVA) in unfavorable lymphoma in relapse or resistant to prior doxorubicin- or novantrone-based regimens. DESIGN AND METHODS: Thirty patients with relapsing or resistant unfavorable lymphoma received a combination of idarubicin 12 mg/m2 i.v. on day 1, etoposide 60 mg/m2 i.v. every 12 hours for 3 days, and Ara-C 1 g/m2 i.v. every 12 hours for 3 days (3-hour infusion). Median age was 39 years (range: 22-60). All patients had been given prior doxorubicin or novantrone; 54% of them had received 2 or more chemotherapy regimens; 67% of total were in clinical relapse (30% in their second relapse), and 23% had resistant disease. RESULTS: The overall response rate to IVA was 60% (18 of 30 patients). Complete remission rate was 20% (6 of 30) in the whole group, 45% (5 of 11) among patients in their first relapse. Remission median duration was 9 months (range: 1-18), with a 3-year relapse-free and overall survival of 20% and 15%, respectively. Severe neutropenia occurred in 13 patients (43%) and severe thrombocytopenia in 11 patients (37%), with a median duration of 9 and 13 days, respectively. No cardiac toxicity developed; sepsis during neutropenia was documented in four instances and two patients (7%) died of therapy-related events (septic shock). INTERPRETATION AND CONCLUSIONS: Idarubicin combined with etoposide and intermediate-dose cytarabine proved to be an active salvage therapy in unfavorable lymphoma given prior doxorubicin or novantrone; the best results were obtained among patients in their first relapse, with low tumor burden.

The risk of acute leukemia in patients treated for Hodgkin's disease is significantly higher aft [see bined modality programs than after chemotherapy alone and is correlated with the extent of radiotherapy and type and duration of chemotherapy: a case-control study.

BACKGROUND AND OBJECTIVE: Patients treated for Hodgkin's disease have an increased risk of developing subsequent acute leukemia. This co-operative study was conducted to assess the relative risk associated with several candidate factors including age, splenectomy, combined modality therapy and cumulative drug dose including alkylating agents and nitrosurea derivatives. DESIGN AND METHODS: This study evaluated the risk of acute leukemia according to pretreatment variables and therapy modalities among 1659 patients treated for Hodgkin's disease and followed for a median time of 10 years. Both case-control and actuarial risk studies were performed. Median age was 34 years (range: 12-83); 53% of patients were splenectomized. As to the overall therapy, 348 patients (21%) were given radiotherapy (RT) alone, 375 (23%) chemotherapy (CT) alone (including MOPP, MOPP + ABVD or MOPP + ABVD + lomustine); 936 (56%) received both CT and RT, either as primary or salvage treatment. RESULTS: The overall 15-year actuarial risk of leukemia was 4.2%; the hazard function curve showed two peaks of risk at the 3th and the 8th year from the initiation of therapy and no leukemia beyond the 12th year of follow-up. Risk of leukemia was 0.3% after RT alone, 2.8% after CT alone (2.2% after MOPP; 4.4% after MOPP + ABVD + lomustine), and 5.4% in patients given combined modality therapy (10.2% for RT + MOPP; 15.6% for RT + MOPP + lomustine). No leukemia occurred after ABVD alone and the risk was low (0.6%) when neither mechlorethamine nor lomustine were utilized. Patients who had received extended radiotherapy including abdomen and pelvis in addition to MOPP showed a significantly higher risk of leukemia compared to those given limited RT + MOPP (P = 0.01). Case-control analysis indicated advanced stage, type and duration (> 8 months) of CT and extension of RT as significant risk factors for leukemia. Compared to RT alone, the odds ratio was 5.9 after MOPP + extended RT, and 8 when a lomustine-containing regimen was used, as well. Neither age nor splenectomy were independent risk factors for leukemia; splenectomy was influential only when patients had been given MOPP chemotherapy, as well. INTERPRETATIONS AND CONCLUSIONS: Both case-control and actuarial analyses indicated that: a) combined modality therapy with MOPP and extensive RT (including abdomen and pelvis), and the use of lomustine added to the leukemogenic risk of MOPP alone; b) programs without mechlorethamine, procarbazine and lomustine were almost devoid of leukemogenic risk.

Nodular lymphocyte predominance Hodgkin's disease: long-term observation reveals a continuous pattern of recurrence.

We evaluated the presenting clinical characteristics and outcome of 68 patients with nodular lymphocyte predominance Hodgkin's disease (NLP-HD), in order to delineate the pattern of evolution of the disease. The male to female ratio was 46/22 and median age 35 yrs (range, 14-86). Eight patients had a history of benign hyperplasia on lymph node biopsies performed 6 to 36 months before the diagnosis of NLP-HD. Early stage disease accounted for 75% of cases. One patient had a coexistent non-Hodgkin's lymphoma (NHL). Treatment was as follows: radiotherapy in 26, chemotherapy in 23, combined modality in 19. CR rate was 93% (63/68). 18 patients relapsed as HD and 5 developed NHL. The cumulative risk of NHL was 9% at 10 yrs. During remission, 4 patients had 5 episodes of follicular hyperplasia histologically documented. Overall survival rate was 71% at 10 yrs and and 63% at 15 yrs. Freedom from progression (FFP) declined from 67% at 5 yrs to 45% at 10 yrs, because of late relapses. Localized disease predicted for a better FFP (p = 0.01), but was not associated with a reduced risk of recurrence over time. NLP-HD is characterized by an indolent course with a constant pattern of relapse over time, also in patients with early stage disease at diagnosis. In addition to relapse as NLP-HD, patients may evolve into a NHL or develop benign lymph nodal hyperplasia. Careful long-term follow up is needed for these patients.

Growth factors in the therapy of myelodysplasia: biological aspects.

Growth factors (GF) are reported to play an important role in the therapy of myelodisplastic syndromes (MDS). After in vitro administration a consistent group of MDS may respond to GF but the possibility of differentiation, regulation or expansion of myelodisplastic clones following GF therapy is still a question to be answered as their optimum dose and combinations. To validate if in vivo treatment with GF, may promote the regulation or the recovery of myelopoiesis and/or modify the clonality of the responses, we gave G-CSF after intensive chemotherapy in high risk MDS and acute leukemia evolving from MDS patients. According to our data the use of G-CSF after intensive chemotherapy may improve the CR rate without increase of leukemic transformation. However the answer were clonal and the remission duration remained very short so we suggest to utilize this time to perform other therapeutic strategies such as, when possible, the BMT.

Early-stage Hodgkin's disease: long-term results with radiotherapy alone or combined radiotherapy and chemotherapy.

BACKGROUND: Controversy still exists over the optimal management of early-stage Hodgkin's disease (HD); presentation features may have a different prognostic impact according to initial therapy, and long-term toxicity must be fully evaluated. PATIENTS AND METHODS: This study included 164 patients with stage IA-IIA HD treated with radiotherapy (RT) alone or combined radio- and chemotherapy (CT) according to presenting features and their attendant prognostic significance. The RT group included 88 patients with favorable prognostic features; the combined modality group included 76 patients with one or more unfavorable features. In the RT group, 85% of patients received extended-mantle or STNI; in the combined modality group, RT consisted of mantle- (49%), extended mantle- (37%), and involved-field irradiation (14%); CT consisted of 6 cycles of MOPP before 1984; 3 cycles of ABVD were substituted for MOPP thereafter. RESULTS: Complete remission was obtained in 94% and 99% of patients of the RT and combined modality groups, respectively. The 10-year actuarial relapse-free survival (RFS) in the RT group was 62% and was influenced by stage (p = 0.04) and histology (p = 0.01); in the combined modality group, RFS was 88% and was influenced by the presence of bulky disease. Overall survival and tumor mortality between the therapy groups were comparable. RT-related toxicity consisted of mediastinal fibrosis (8 cases), myelitis (3), hypothyroidism (2); other long-term events included 2 cases of acute leukemia in the combined MOPP and RT group. Altogether, 8 of 20 patients who died were in their first complete remission. CONCLUSIONS: In stage IA-IIA HD, the combined modality therapy reduced the risk of relapse compared to radiation alone; long-term toxicity of RT was not negligible and relapses could occur late.

Analysis of long-term results and prognostic factors among 138 patients with advanced Hodgkin's disease treated with the alternating MOPP/ABVD chemotherapy.

BACKGROUND: A prospective study was conducted to assess (a) the long-term results and toxicity of the alternating MOPP/ABVD regimen in advanced Hodgkin's disease; (b) the prognostic value of pretreatment variables and of drug dose intensity. PATIENTS AND METHODS: A total 138 consecutive patients with advanced Hodgkin's disease entered this study; patient selection included stages IIB (33% of total), IIIB (26%), IV (25%), and stages IIA-IIIA (16%) with bulky disease and pulmonary hilum involvement. The MOPP/ABVD program was delivered in an 8-month program; adjuvant radiotherapy on sites of bulky disease was delivered in 24 patients. RESULTS: Complete remission was obtained in 106 (77%) patients; significant factors for CR in univariate analysis were stage, symptoms, histology, and bone marrow involvement. The five-year relapse-free survival (RFS) was 83%; in a multivariate analysis, histology only correlated with RFS (p = 0.04). The five-year freedom from tumor mortality and overall survival (OS) were 79% and 67%, respectively. An adverse prognostic significance for OS was observed for B symptoms and bone marrow involvement. The median percentage of relative dose intensity (RDI) was as follows: Adriamycin 86, mechlorethamine 85, vincristine 73, vinblastine 84, bleomycin 79, procarbazine 74, dacarbazine 81. No significant association was found between RDI and clinical outcome. No severe pancytopenia or life-threatening complications occurred during therapy. CONCLUSIONS: Alternating MOPP and ABVD cured more than 65% of patients with advanced HD; acute and late toxicity were acceptable. Prognostic analysis defined subgroups with a lower chance of cure which may deserve a more intensive initial therapy.

Results of CAV regimen (CCNU, melphalan, and VP-16) as third-line salvage therapy for Hodgkin's disease.

BACKGROUND: A prospective study was conducted to assess the efficacy and toxicity of a salvage regimen consisting of CCNU, Melphalan, and VP-16 (CAV) given at 28-day intervals in patients with Hodgkin's disease (HD) relapsing after primary therapy or refractory to the alternating MOPP/ABVD regimen. PATIENTS AND METHODS: This study included 58 patients (median age: 34 years), with resistant or relapsing HD. Primary therapy had consisted of alternating MOPP/ABVD (81%) or MOPP alone (19%); 38% of patients were relapsing from prior complete remission (CR) while 62% had resistant disease. Extranodal disease was present in 55% and B-symptoms in 72% of patients; one-fifth had bulky disease and/or bone marrow involvement. The CAV was used as first salvage in half of the patients. RESULTS: Complete remission was obtained in 17 patients (29%); unfavorable factors for CR in univariate analysis were the presence of bulky disease and the failure to achieve CR with prior therapy. Nine patients (53% of remitters) have subsequently relapsed with a 10-month median duration of CR. The 3-year overall survival after CAV was 25% with an 18-month median survival; significant differences in survival were found according to the extent of disease, the presence of B-symptoms and the HD status (prior sensitive or resistant disease, first or subsequent relapse). Seven patients are long-term remitters (12%), and one of them has been given high-dose chemotherapy and autologous bone marrow transplantation at relapse after CAV. The CAV toxicity was mostly hematological; severe pancytopenia occurred in six cases with two cases of fatal infections and one of fatal hemorrhage. CONCLUSION: CAV therapy was moderately effective as third-line salvage in patients with HD resistant to alternating MOPP/ABVD or previously given two different regimens for relapse; the toxicity was mostly hematological and supportive therapy was needed in one-third of the patients.
