High-dose therapy and autologous stem-cell transplantation for adult patients with Hodgkin's disease who do not enter remission after induction chemotherapy: results in 175 patients reported to the European Group for Blood and Marrow Transplantation. Lymphoma Working Party.

PURPOSE: To investigate the results of high-dose therapy and autologous stem-cell transplantation (ASCT) in adults with Hodgkin's disease who do not enter remission after induction therapy, to determine overall survival (OS) and progression free survival (PFS), and to identify prognostic factors. PATIENTS AND METHODS: A retrospective analysis of 175 patients reported to the European Group for Blood and Marrow Transplantation between November 1979 and October 1995. One hundred were male and 75 were female, with a median age of 26.5 years. Responses to first-line therapy were defined as progressive disease (PD) in 88 and stable/minimally responsive disease (SD/MR) in 87. Seventy-five patients received ASCT after failure of one induction regimen. Second-line therapy was given to the remaining 100 patients. Response to second-line therapy was PD in 34 and SD/MR in 66. OS and PFS rates were determined, and prognostic factors were investigated using univariate and multivariate analyses. RESULTS: Responses to high-dose therapy and ASCT were complete response (30%), partial response (28%), no response (14%), PD (14%), and toxic death (14%). Actuarial 5-year OS and PFS rates were 36% and 32%, respectively. In univariate analysis for PFS and OS, adverse factors were use of a second-line chemotherapy regimen and interval of more than 18 months between diagnosis and ASCT. In multivariate analysis, the interval between diagnosis and ASCT maintained prognostic significance for OS. Response to the chemotherapy regimen given immediately before ASCT had no predictive value. CONCLUSION: High-dose therapy and ASCT is an effective treatment strategy for patients with Hodgkin's disease for whom induction chemotherapy fails. Outcome was equivalent for those with obvious PD or SD/MR in response to the regimen given immediately before high-dose therapy. Prospective randomized studies are required to compare this approach with conventional-dose salvage therapy.     

Role of radiation therapy in the treatment of stage I/II mucosa-associated lymphoid tissue lymphoma.

BACKGROUND: Few large studies exist on the outcome of patients treated for stage I/II mucosa-associated lymphoid tissue (MALT) lymphoma. PATIENTS AND METHODS: We retrospectively reviewed the records of 77 patients consecutively treated for stage I (n = 66) or II (n = 11) MALT lymphoma at our institution. Progression-free survival (PFS), freedom from treatment failure (FFTF), and overall survival (OS) were calculated using the Kaplan-Meier method. RESULTS: The median follow-up time was 61 months (range 2-177 months). Fifty-two patients (68%) received local radiation therapy (RT) alone, 17 (22%) had surgery followed by adjuvant RT, five (6%) had surgery alone, two (3%) had surgery and chemotherapy, and one patient had chemotherapy alone. The median RT dose was 30 Gy (range 18-40 Gy). The 5-year PFS, FFTF, and OS rates were 76%, 78%, and 91%, respectively. The 5-year PFS (79% versus 50%; P = 0.002) and FFTF (81% versus 50%; P = 0.0004) rates were higher for patients who received RT as compared with patients who did not. CONCLUSIONS: The prognosis following treatment of stage I/II MALT lymphoma is excellent. RT improves PFS and FFTF and has an important role in the curative treatment of patients with localized disease.     

Restaging with gallium scan identifies chemosensitive patients and predicts survival of poor-prognosis mediastinal Hodgkin's disease patients

Following treatment of mediastinal Hodgkin's disease (HD), residual masses are frequent and gallium scanning has proven to be of value in the evaluation of their specificity (fibrosis or active disease). This study assessed, for relapse and survival, the predictive value of restaging gallium scan of patients with a residual mass on computed tomography scan after induction chemotherapy. Between 1/89 and 12/97, in 53 newly diagnosed HD patients with a residual mediastinal mass, a gallium scan was performed after chemotherapy (3 or 4 courses) and always before consolidative radiotherapy. Characteristics at diagnosis were: nodular sclerosis histology, 89%; bulky mediastinal disease, 79%; B-symptoms, 51%. Results: gallium scan was positive in 16 patients (30%) and negative in 37 (70%). At median follow-up period of 36 months, freedom-from-progression rate was 86% versus 19% (P<0.0001) for patients with negativevs positive gallium scans, respectively. The 5-year overall survival (OS) rate was 68% and differed significantly (P<0.0001) between negative (91%) and positive (25%) gallium scanning groups. The specificity of gallium scanning was 91% and the sensitivity 72% with a positive predictive value of 81% and a negative predictive value of 86%. Evaluation with gallium scan after induction chemotherapy identifies chemosensitive patients among those with poorprognosis mediastinal HD. Although relapse may occur in patients with negative gallium scan, a postive gallium scan is highly predictive of failure and poor outcome, and treatment should thus be modified.     

Gallium-67 scans as an adjunct to computed tomography scans for the assessment of a residual mediastinal mass in pediatric patients with Hodgkin's disease. A Pediatric Oncology Group study

This study determines the utility of gallium-67 (Ga-67) scintigraphs as an adjunct to computed tomography (CT) scans for the assessment of residual mediastinal masses in children and adolescents with advanced-stage Hodgkin's disease. At diagnosis 42 patients with CT scan-documented mediastinal disease had a Ga-67 scan performed. Thirty-four of 42 patients (81%) had gallium-avid mediastinal lesions, whereas in eight (19%), the Ga-67 scan was negative. At the completion of eight cycles of therapy of Mustargen (mechlorethamine), Oncovin (vincristine), procarbazine, prednisone (MOPP) alternating with doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD), 21 of 34 patients with initially positive Ga-67 scans had them repeated; 18 of 21 converted to negative results, and three remained positive. In 11 of 18 patients, the loss of gallium avidity was consistent with a negative mediastinal CT scan. In seven, although the gallium scan was negative, the CT scan remained positive; all seven patients had a mediastinal biopsy of suspected residual disease and in all seven the biopsy results were negative for Hodgkin's disease. These preliminary results in a small cohort of patients demonstrate that Ga-67 scans may be of benefit in evaluating residual mediastinal masses in patients with Hodgkin's disease.     

Comparison of MOPP versus ABVD as salvage therapy in patients who relapse after radiation therapy alone for Hodgkin's disease.

BACKGROUND: The aim of this study was to determine salvage outcome in patients with Hodgkin's disease who relapse after radiation therapy, and to compare the efficacy of mechlorethamine, Oncovin, procarbazine and prednisone (MOPP) versus Adriamycin, bleomycin, vinblastine and dacarbazine (ABVD) as salvage treatment. PATIENTS AND METHODS: One hundred patients with Hodgkin's disease (97 with stage I-II disease at presentation) who relapsed after radiation therapy alone were salvaged with either MOPP or ABVD. Freedom from second relapse (FFSR) and overall survival (OS) were determined, and prognostic factors for salvage outcome were evaluated. RESULTS: The median follow-up time since salvage therapy was 12 years. The 10-year FFSR and OS rates were 70% and 89%, respectively. Forty-one patients were salvaged with MOPP and 59 received ABVD. The type of salvage chemotherapy did not significantly influence FFSR or OS. Age >50 years at initial diagnosis was the only significant predictor for an inferior FFSR and OS on both univariate and multivariate analyses. CONCLUSIONS: The two salvage regimens of MOPP and ABVD had similar efficacy in this group of patients with predominantly early-stage disease at initial radiation therapy. The inferior salvage outcome in patients aged >50 years is a contributing factor to the overall poor prognosis of patients presenting with Hodgkin's disease at an older age.     

Three cycles of ABDV plus extended field radiotherapy in patients with poor prognosis early-intermediate stage Hodgkin's disease

The aim of the study was to verify the possibility of treating patients with poor prognosis early-intermediate Hodgkin's disease with a combined modality therapy consisting of three cycles of ABVD followed by extended field irradiation (EFRT). No patient had bulky mediastinum or had previously been administered chemo- or radiotherapy. At pathological restaging, 40/44 (91%) evaluable patients achieved complete responses (CR). After a ten-year followup, freedom from progression (FFP), relapse-free survival (RFS) and overall survival (OS) were 80%, 83% and 81%, respectively. Of the prognostic factors, univariate analysis showed that only stage III negatively influenced RFS, but not OS. Toxicity was mild except for subclinical mediastinal fibrosis in 32.5% of CR patients. No patient reported reduced fertility. Two cases of second neoplasms were recorded: one ameboid glioma and one thymoma, both occurring within five years after discontinuing chemo-radiotherapy. Our data suggest that three cycles of ABVD preceeding EFRT is an effective treatment for poor prognosis early-intermediate stage Hodgkin's disease; nevertheless, stage III patients and some stage II patients with unfavorable prognostic factors should be treated with a more aggressive approach.     

Combination chemotherapy plus low-dose involved-field radiotherapy for early clinical stage Hodgkin's lymphoma

PURPOSE: To present our long-term experience regarding the use of chemotherapy plus low-dose involved-field radiotherapy (IFRT) for clinical Stage I-IIA Hodgkin's lymphoma. METHODS AND MATERIALS: We analyzed the data of 368 patients. Of these, 66 received mechlorethamine, vincristine, procarbazine, and prednisone (MOPP) and 302 received doxorubicin (or epirubicin), bleomycin, vinblastine, and dacarbazine [A(E)BVD]. Patients with complete remission or very good partial remission were scheduled for low-dose IFRT (< or =3200 cGy). RESULTS: The 10-year failure-free survival (FFS) and overall survival (OS) rate was 85% and 86%, respectively. A(E)BVD-treated patients had superior 10-year FFS and OS rates compared with MOPP-treated patients (87% vs. 75%, p = 0.009; and 93% vs. 71%, p = 0.0004, respectively). Only 10 of 41 relapses had any infield (irradiated) component. Of the complete responders/very good partial responders treated with low-dose IFRT, those who received <2800 cGy had inferior FFS but similar OS as those who received 2800-3200 cGy. Adverse prognostic factors for FFS included age > or =45 years, leukocytosis > or =10 x 10(9)/L, and extranodal extension. Secondary acute leukemia developed after MOPP with or without salvage therapy (n = 6) or after ABVD plus salvage therapy (n = 2). None of the nine secondary solid tumors developed within the RT fields. CONCLUSION: IFRT at a dose of 2800-3000 cGy is highly effective in clinical Stage I-IIA HL patients who achieved a complete response or very good partial response with A(E)BVD. The long-term toxicity with respect to secondary malignancies appears to be acceptable.     

Hodgkin's disease in elderly patients (> or =60): clinical outcome and treatment strategies

PURPOSE: Older age is an adverse prognostic factor for survival for patients with Hodgkin's disease. This study assessed the outcome of elderly patients (>or=60 years) with Hodgkin's disease treated with curative intent in an attempt to identify the optimal treatment strategies for this group of patients. METHODS AND MATERIALS: Eighty-six patients, 60-93 years old at the time of diagnosis, were treated for Hodgkin's disease with radical intent between 1969 and 1995. All patients underwent radiographic staging of the chest, abdomen, and pelvis, and 17 patients underwent staging laparotomy. Fifty-two patients had early-stage disease (Stage IA-IIA) and 34 had Stage IIB-IV Hodgkin's disease. The median follow-up time was 75 months (range 24-267) for surviving patients. RESULTS: The 10-year actuarial freedom from treatment failure (FFTF) rate for all patients was 62%. The 10-year FFTF rate for patients with Stage IA-IIA and Stage IIB-IV disease was 71% and 49%, respectively (p = 0.03). Patients with early-stage disease treated with chemoradiotherapy had a lower crude rate of treatment failure (20%) than patients treated with either chemotherapy alone (33%) or radiotherapy alone (46%). However, no statistically significant difference was found between the treatment groups in terms of actuarial FFTF or overall survival. The 5- and 10-year overall survival rate (all causes) for all patients was 48% and 30%, respectively. The 10-year survival rate for patients with Stage IA-IIA and Stage IIB-IV disease was 31% and 26%, respectively (p = 0.07). On multiple regression analysis, including age, treatment, and stage in the Cox regression model with respect to overall survival, age was a marginally significant factor (p = 0.08). For FFTF, age was not a significant factor in the model (p = 0.11). We analyzed the subsequent outcome of patients who developed a first recurrence after initial treatment; the 5-year survival rate was only 20% after recurrence of Hodgkin's disease. Initial treatment was reasonably well tolerated. CONCLUSION: Although more patients died of other causes than Hodgkin's disease, the recurrence of Hodgkin's disease had a significant impact on survival. Thus, we favor the use of chemoradiotherapy in early-stage patients >60 years to minimize the risk of relapse.     

Treatment of pediatric Hodgkin's disease with chemotherapy alone or combined modality therapy

Optimal treatment for Hodgkin's disease during childhood is unknown. We report the treatment outcome of patients with Hodgkin's disease <13 years of age seen at the American University of Beirut Medical Center (AUBMC) between 1980 and 1996. A retrospective review of the medical records of 24 children treated for HD at AUBMC was performed. Treatment consisted of chemotherapy alone (n = 15) or chemotherapy plus involved field radiotherapy (n = 9). Chemotherapy consisted of COPP, ABVD, or alternating cycles of each for a total of 6 to 12 cycles, depending on clinical and radiological response; three patients received MOPP. Five patients in the chemotherapy group had clinical stage (CS) I and II and 10 had CS III disease. In the combined modality group, eight patients had CS I and II and one had CS IV disease. At a median follow-up of 5 years, the event-free survival (EFS) for the combined modality group was 100% and the overall survival (OS) 100%. For the chemotherapy alone group, the EFS was 56% and the OS was 79%. Four patients (27%) in the chemotherapy alone group who had Stage IIIB disease relapsed. Mean time to relapse was 4.3 years. In our experience, six cycles of COPP or (COPP plus ABVD) alone were suboptimal for the treatment of Stage IIIB Hodgkin's disease patients, especially those with involvement of lower abdominal nodes (III2B), extensive pulmonary disease, or mixed cellularity histology. Radiation therapy or additional chemotherapy courses are required for these patients.     

A Contribution to solve the problem of the need for consolidative radiotherapy after intensive chemotherapy in advanced stages of Hodgkin's lymphoma--analysis of a quality control program initiated by the radiotherapy reference center of the German Hodgkin Study Group (GHSG)

PURPOSE: The role of radiotherapy (RT) after intensive chemotherapy in patients with advanced stage Hodgkin's lymphoma (HL) is still unclear. The German Hodgkin Study Group (GHSG) randomized HD12 trial was designed to test whether consolidative RT in the region of initial bulky disease and of residual disease is necessary after effective chemotherapy. A quality control program based on a multidisciplinary panel of radiation oncologists, radiologists, and medical oncologists who reviewed all patients' staging and restaging imaging was initiated. METHODS AND MATERIALS: A total of 1661 patients aged 16 to 65 years with HL in Stage IIB (large mediastinal mass and/or E-lesions) or Stage III to IV were randomized from January 1999 to January 2003 according to a factorial design between: 8 esc.BEACOPP + RT (arm A), 8 esc.BEACOPP non-RT (arm B), 4+4BEACOPP + RT (arm C), 4+4BEACOPP non-RT (arm D). RESULTS: In the fifth interim analysis, 1449 patients were eligible for the arm comparison with regard to RT. After a median observation time of 48 months the FFTF rate was 86% and the OS 92%. The FFTF was 95% in the RT arms A+C and 88% in the non-RT arms B+D: no sequential significant difference. One thousand and eighty four patients were evaluated by the panel. The panel defined initial bulky disease in 800 patients and residual disease in 600 patients. The panel recommended continuation of therapy according to the randomization for 934 of 1084 patients and additive RT independently from the randomization arm for 145 of 1084 patients. CONCLUSIONS: The study showed that RT can be reduced substantially after effective chemotherapy. However, because of the irradiation of 10% of patients in the non-RT arms, equivalent effectiveness of a non-RT strategy cannot be proved. A substantial limitation of consolidative RT according to expert panel recommendations appears to be possible without reducing effectiveness.     

Hodgkin's lymphoma in elderly patients: a comprehensive retrospective analysis from the German Hodgkin's Study Group.

PURPOSE: With improved prognosis for patients with Hodgkin's lymphoma (HL), interest increasingly focuses on high-risk groups such as elderly patients. We thus performed a retrospective analysis using the German Hodgkin's Study Group (GHSG) database to determine clinical risk factors, course of treatment, and outcome in elderly HL patients in comparison with younger adults. PATIENTS AND METHODS: A total of 4,251 patients included in the GHSG studies HD5 to HD9 were analyzed, of whom 372 (8.8%) were 60 years or older and 3,879 (91.2%) were younger than 60 years. Patient characteristics, treatment results, toxicity, freedom from treatment failure (FFTF), and overall survival (OS) were compared. RESULTS: Elderly patients more often had mixed cellularity subtype, "B" symptoms, elevated erythrocyte sedimentation rate, and poorer performance status. Less frequently observed were nodular sclerosis subtype, large mediastinal mass, and bulky disease. Acute toxicity during chemotherapy was generally higher in elderly patients. This was most obvious for severe infections (grade 3 or 4; 15% v 6%) correlating with more severe leukopenia in elderly patients (grade 4; 38% v 23%). As a result, significantly fewer elderly patients received the intended full chemotherapy dose (75% v 91%). The survival analysis showed a significantly poorer treatment outcome for elderly patients in terms of 5-year OS (65% v 90%), FFTF (60% v 80%), and HL-specific FFTF (73% v 82%). CONCLUSION: Elderly patients have a poorer risk profile compared with younger HL patients and experience more severe treatment-associated toxicity. Higher mortality during treatment as well as lower dose-intensity are the major factors explaining the poorer overall outcome of elderly HL patients.     

Long-term outcome and mortality trends in early-stage, Grade 1-2 follicular lymphoma treated with radiation therapy

PURPOSE: To analyze long-term outcomes and causes of death in patients receiving radiation therapy (RT) for localized, low-grade follicular lymphoma. METHODS AND MATERIALS: Between 1972 and 2000, 106 patients with Stage I-II, Grade 1-2 follicular lymphoma received RT alone or radiation and chemotherapy (RT/CT). Seventy-four percent had Stage I, and 26% had Stage II disease. Seventy-six percent received RT alone, and 24% received combined RT/CT. Second malignancy rates were compared with an age- and sex-matched population. RESULTS: Median follow-up was 12 years. Median survival time was 19 years. The 5-, 10-, and 15-year overall survival (OS) rates were 93%, 75%, and 62%, respectively. Age > or = 60 was the only significant adverse prognostic factor with respect to OS. There were 35 deaths, 20 of which were attributable to lymphoma. Freedom from treatment failure (FFTF) rates at 5, 10, and 15 years were 72%, 46%, and 39%, respectively. Forty-seven patients (48%) relapsed. Tumor size > 3 cm was the only significant adverse factor for FFTF. Observed incidence of second malignancy did not significantly exceed expected incidence. CONCLUSIONS: Although patients with early-stage, low-grade follicular lymphoma have long median survival, the leading cause of death remains lymphoma. However, patients receiving RT do not have significantly elevated cumulative incidence of second malignancy.     

Consolidation radiation after complete remission in Hodgkin's disease following six cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine chemotherapy: is there a need?

PURPOSE: Combined modality treatment using multidrug chemotherapy (CTh) and radiotherapy (RT) is currently considered the standard of care in early stage Hodgkin's disease. Its role in advanced stages, however, continues to be debated. This study was aimed at evaluating the role of consolidation radiation in patients achieving a complete remission after six cycles of doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy using event-free survival (EFS) and overall survival (OS) as primary end points. PATIENTS AND METHODS: Two hundred and fifty-one patients with Hodgkin's disease attending the lymphoma clinic at the Tata Memorial Hospital (Mumbai, India) from 1993 to 1996 received induction chemotherapy with six cycles of ABVD after initial staging evaluation. A total of 179 of 251 patients (71%) achieved a complete remission after six cycles of ABVD chemotherapy and constituted the randomized population. Patients were randomly assigned to receive either consolidation radiation or no further therapy. RESULTS: With a median follow-up of 63 months, the 8-year EFS and OS in the CTh-alone arm were 76% and 89%, respectively, as compared with 88% and 100% in the CTh+RT arm (P =.01; P =.002). Addition of RT improved EFS and OS in patients with age < 15 years (P =.02; P =.04), B symptoms (P =.03; P =.006), advanced stage (P =.03; P =.006), and bulky disease (P =.04; P =.19). CONCLUSION: Our study suggests that the addition of consolidation radiation helps improve the EFS and OS in patients achieving a complete remission after six cycles of ABVD chemotherapy, particularly in the younger age group and in patients with B symptoms and bulky and advanced disease.     

Evaluation of therapeutic modalities in the control of Hodgkin's disease

The results achieved in three different studies carried out on patients affected by Hodgkin's disease are discussed. In study No. 1, 58 patients with pathological Stage I-II were treated with only a "Mantle" field irradiation. The complete remission (CR) rate was 98% with an actuarial overall survival of 90%, and a median of follow-up of 80 months. Thirty-one percent of patients relapsed. In study No. 2, 42 patients were randomly allocated to receive only MOPP chemotherapy versus extended field irradiation; CR rate was 68 and 95%, respectively (p less than 0.05). The overall survival rate was 100% in the radiotherapy group and 82% in the MOPP group. No relapses have been observed in patients treated with MOPP. In study No. 3, 218 patients affected by advanced Stage HD were randomly treated with 6 cycles of MOPP chemotherapy versus 6 cycles of ABVD chemotherapy. In the MOPP group the CR rate, the relapse-free survival rate (RFS), and overall survival (OS) rates at 60 months were 77, 68, and 76% respectively, whereas, in the ABVD group the CR, the RFS, and OS rates at 60 months were 75, 77 and 80% respectively, (p less than 0.05). These data and statistical comparisons are analyzed.     

Intermediate stage Hodgkin's disease: preliminary results on 210 patients treated with four ABVD chemotherapy cycles plus extended versus involved field radiotherapy

BACKGROUND: To improve long-term survival by reducing toxicity in intermediate stage Hodgkin's disease patients, we compared the effects of involved field (IF) versus extended field (EF) irradiation administered after four cycles of ABVD regimen. MATERIALS AND METHODS: Two hundred and ten Hodgkin's disease patients, at clinical stage II with risk factors and III without risk factors, were enrolled in the randomized study HD94. After four courses of ABVD regimen, patients who achieved complete remission (CR) or partial remission (PR) were randomly assigned to the IF or EF arm. The Kaplan-Meier method was adopted to estimate overall survival (OS) and relapse-free survival (RFS). RESULTS: After a median follow-up of 78 months (range 13-111 months), OS was 98% and 96%, respectively, in the EF and IF arms; RFS was 94% and 91%, respectively, in the EF and IF arms. Conclusion: We confirm the efficacy of four cycles of ABVD regimen, with suitable dose intensity, and radiotherapy as consolidation therapy, in intermediate stage Hodgkin's disease patients (CR = 99.5% and OS = 95%). We also found that involved field radiotherapy results were as effective as extended field, without acute toxicity.     

Survival analysis of clinical, pathologic, and genetic features in neuroblastoma presenting as locoregional disease

BACKGROUND: Locoregional neuroblastoma is a clinical subgroup characterized by the absence of distant metastasis (International Neuroblastoma Staging System Stages 1, 2, and 3). Although these patients generally have an excellent survival with minimal therapy, some do experience recurrence with lethal consequences. METHODS: To identify risk factors for disease progression, the authors performed a retrospective analysis of clinical (age and stage) and tumor biologic markers (histology, MYCN, DNA index, and allelic analysis of chromosomes 1p, 11q12-qter, and 14q12-q32) in 44 patients (10 Stage 1, 18 Stage 2, and 16 Stage 3). Allelic analysis was performed using polymorphic polymerase chain reaction markers in a semiautomated, fluorescent detection system. RESULTS: Sixteen patients (38%) were younger than 365 days at diagnosis. Seventeen of 39 tumors (43%) had unfavorable histology, 6 (13%) were MYCN amplified, 14 (31%) were diploid, 17 (38%) had 1p36 loss of heterozygosity (LOH), 11 (25%) had 1p22 LOH, 10 (22%) had 11q LOH, and 13 (29%) had 14q LOH. Seventeen patients (38%) progressed, including 6 who progressed to Stage 4 disease (13%). Sixteen patients with progressive disease received cytotoxic therapy. Thirty-seven patients are alive (84%) with a median follow-up of 51 months. By permutation log rank test, both MYCN amplification and diploidy were associated with overall survival (OS), but only diploidy was associated with progression free survival (PFS) and progression to Stage 4 disease. LOH of 1p36, 1p22, 11q, or 14q did not show correlation with either OS or PFS. CONCLUSIONS: Locoregional neuroblastoma tumors with diploid DNA index, regardless of other biologic features, have increased risk of local recurrence and Stage 4 progression.     

Mantle irradiation alone for pathologic stage I and II Hodgkin's disease: long-term follow-up and patterns of failure.

PURPOSE: We performed a retrospective study to determine the long-term outcome, patterns of failure, and prognostic factors for patients with pathologic Stage I or II Hodgkin's disease (HD) who were treated with mantle irradiation alone. METHODS AND MATERIALS: The medical records of 145 patients with pathologic Stage I or II supradiaphragmatic Hodgkin's disease treated with mantle irradiation alone between June 1967 and June 1991 were reviewed. Patterns of failure, overall survival (OS) rate, and progression-free survival (PFS) rate were determined. Univariate and multivariate analyses were performed to identify adverse prognostic factors for OS and PFS. The number of adverse prognostic factors per patient was counted, and a prognostic score was assigned to each patient. The log-rank test was used to compare the OS or PFS rates among patients with prognostic scores 0, 1, and 2. RESULTS: The median patient age was 27 years (range 10-66), with almost even male to female distribution. Every patient had splenectomy and negative laparotomy (LAP). Fifty-one patients had Stage I disease (IA-49, IB-2) and 94 Stage II (IIA-89, IIB-5). The histologic subtypes were nodular sclerosing in 110, mixed cellularity in 28, lymphocyte predominance in 5, lymphocyte depleted in 1, and unclassified in 1. Twelve patients with Stage II disease had >/= 3 sites of nodal involvement. Fifty-four patients had a prognostic score of 0, 70 of 1, and 21 of 2. The median follow-up time for the 109 surviving patients was 146 months (range 25-381). The 10- and 20-year actuarial OS rates for the whole group were 87.6% and 65.3%, respectively. The corresponding actuarial PFS rates were 75.3% and 74.2%, respectively. Thirty-six patients (9 Stage I, 27 Stage II) had relapses in a total of 41 sites. Failures by histology were 29 patients with nodular sclerosing, 6 with mixed cellularity, and 1 with lymphocyte predominance. Failures by sites were: trans-diaphragmatic, 22 (para-aortic nodes, 15; as the only site of progression in 12; visceral, 7; as the only site of progression in 5); within radiation field, 8; marginal miss, 8 (as the only site of failure in 2); and unknown, 3. The majority of the failures occurred within 5 years of diagnosis. Long-term side effects of radiation included cardiac complications in 30 patients, with 10- and 20-year actuarial cardiac complication rates of 12.6% and 35.1%, respectively; secondary solid tumors in 14, with 10- and 20-year actuarial rates of 2.3% and 25.7%, respectively; leukemia in 4; non- Hodgkin's lymphoma in 4, with the 10- and 20-year actuarial rates for leukemia and non-Hodgkin's lymphoma of 4.0% and 13.9%; and hypothyroidism in 38. Four adverse prognostic factors were identified for PFS: age > or = 40 years, > or = 3 sites of involvement, male sex, and constitutional symptoms. The prognostic score correlated with patients' outcome as indicated by PFS and OS rates. Patients with a prognostic score of 0 did significantly better than those with a score of 1 or 2. CONCLUSION: In this select group of patients with pathologic Stage I and II Hodgkin's disease treated with mantle irradiation alone, the OS and PFS rates at 10 and 20 years were comparable to those reported in the literature. The major pattern of disease progression was relapse below the diaphragm, therefore close surveillance of the abdomen is warranted. The prognostic score used in our series may predict the patient's outcome, and might be worth testing in a prospective trial. In our series, patients with a prognostic score of 0 had excellent long-term survival, indicating adequate treatment with mantle irradiation alone. Late complications of the treatment pose a significant threat for the patient's survival with long-term follow-up.     

Primary bone lymphoma: treatment results and prognostic factors with long-term follow-up of 82 patients

BACKGROUND: To the authors' knowledge, there is limited information on the preferred treatment and long-term prognosis of primary bone lymphomas (PBLs). All PBL cases treated at the study center between 1963 and 2003 were analyzed to determine patient, disease, and treatment factors that could affect outcome measured by overall survival (OS), cause-specific survival (CSS), and freedom-from-treatment failure (FFTF). METHODS: A total of 101 patients with PBL diagnosed at the study institution were identified. Nineteen patients were excluded because they transferred their treatment or follow-up to another center. Disease control, survival, and prognostic factors were analyzed for all 82 remaining patients. RESULTS: The median age of the patients was 48 years (range, 11-83 years). Approximately 80% presented with diffuse large-cell lymphoma (DLCL), and 81% presented with Ann Arbor Stage I or II disease. Approximately 57% were treated with combined modality therapy, 14% were treated with radiation therapy alone, and 30% were treated with chemotherapy alone. The median follow-up was 67 months (range, 2-280 months). The 5-year OS, CSS, and FFTF were 88%, 96%, and 81%, respectively. The 5-year OS for patients treated with combined modality versus single-modality therapy was 95% versus 78% (P = .013), and the 5-year FFTF for patients treated with combined modality versus single-modality therapy was 90% versus 67% (P = .025). The 5-year CSS for patients treated with combined modality versus single-modality therapy was 95% versus 83% (P = .065). Using a Cox regression for multivariate analysis, age < 40 years and use of combined modality therapy were found to be favorable prognostic factors for OS, CSS, and FFTF. CONCLUSIONS: To the authors' knowledge, the current study is the largest series of patients with PBL treated with modern curative modalities. The data demonstrate that primary lymphoma involving the bone has an excellent prognosis. Patients with PBL treated with combined modality versus single modality therapy were found to have a superior outcome, with a significantly better survival.     

Could BEACOPP be the new standard for the treatment of advanced Hodgkin's lymphoma (HL)?

In 1992, the German Hodgkin Study Group (GHSG) developed the BEACOPP regimen for further improving the outcome of patients with advanced Hodgkin's lymphoma (HL). Since then, BEACOPP has been introduced in 3 different prospective randomized clinical trials of the GHSG to find an equilibrium between maximal efficacy and least toxicity with the BEACOPP principle for the treatment of advanced stage HL. In the HD9 trial of the GHSG, with 1,186 patients, after a median observation time (mot) of 7 years, the rates for freedom from treatment failure (FFTF) are 85 percent, and for overall survival (OS) 90 percent for dose-escalated BEACOPP, and for COPP/ABVD (C/ABVD comparable to ABVD) the rate for FFTF is 67 percent, and for OS it is 79 percent. These superior BEACOPP results are obtained inspite of a higher rate of secondary AML/MDS in the esc. BEACOPP arm. The number of toxic deaths during treatment, however, was lower for esc. BEACOPP (1.6 percent) than for C/ABVD (1.8 percent). The majority of patients were treated in outpatient setting, in a multicenter study with more than 400 centers, including 120 private doctors, in Germany and 9 other European countries. The reduce acute and longterm toxicity, the GHSG started in the consecutive studies HD12 and HD15 for advanced stage HL to de-escalate BEACOPP by reducing the number of escalated BEACOPP cycles and by applying the baseline-dose BEACOPP, a time-dense regimen, called BEACOPP-14. The excellent results obtained with the BEACOPP principle challenge the seemingly global consensus that ABVD is the gold standard treatment strategy for advanced stage HL.     

Long-term results of a prospective trial of mantle irradiation alone for early-stage Hodgkin's disease.

BACKGROUND: To determine the long-term treatment outcome and late effects of mantle irradiation alone in selected patients with early-stage Hodgkin's disease. METHODS: Between 1988 and 2000, 87 patients with pathologic stage (Ann Arbor) I-IIA or clinical stage IA Hodgkin's disease were entered on to a prospective trial of mantle irradiation alone. Patients with B symptoms, large mediastinal adenopathy, or subcarinal or hilar involvement were excluded. The median doses to the mantle field and mediastinum were 36 Gy (range 30.3-40) and 38.6 Gy (range 30.6-44), respectively. The actuarial freedom from treatment failure (FFTF) and overall survival (OS) rates were calculated using the Kaplan-Meier technique. RESULTS: The median follow-up was 107 months (range 23-192). Thirteen of 87 patients (15%) relapsed at a median of 30 months (range 5-62). The 5- and 10-year actuarial FFTF rates were 86% and 84.7%, respectively. All 13 patients who relapsed are alive without evidence of disease at a median of 84 months (range 30-156) post-salvage therapy. Five patients developed a second malignancy at a median of 93 months (range 27-131). The 10-year actuarial risk of a second malignancy was 4.5%. There have been two deaths to date, both due to second malignancies. The 10-year OS rate was 98.2%. CONCLUSION: In selected patients with early-stage Hodgkin's disease, mantle irradiation alone has an excellent long-term survival rate, comparing favorably with the previous standard treatment of extended-field radiation therapy and the current standard of combined modality therapy.
