Is radiotherapy curative for stage I and II low-grade follicular lymphoma? Results of a long-term follow-up study of patients treated at Stanford University.

PURPOSE: To evaluate retrospectively the results of radiotherapy for 177 patients with stage I (n = 73 [41%]) and II (n = 104 [59%]) follicular small cleaved-cell and follicular mixed small cleaved-cell and large-cell non-Hodgkin's lymphoma (NHL) treated in the Department of Radiation Oncology, Stanford University between 1961 and 1994. PATIENTS AND METHODS: Histology was follicular small cleaved-cell in 101 (57%) cases and follicular mixed small cleaved-cell and large-cell in 76 (43%). Forty-five patients (25%) had staging laparotomy; 34 (19%) had extranodal involvement. All patients had received radiotherapy, either to one side of the diaphragm (involved or extended field) or to both sides (total lymphoid irradiation [TLI] or subtotal lymphoid irradiation [STLI]. Radiotherapy doses ranged from 35 to 50 Gy. RESULTS: The median follow-up duration was 7.7 years. The longest follow-up duration was 31 years. Actuarial survival rates at 5, 10, 15, and 20 years were 82%, 64%, 44%, and 35%, respectively. The median survival time was 13.8 years. At 5, 10, 15, and 20 years, 55%, 44%, 40%, and 37% of patients, respectively, were relapse-free. Only five of 47 patients who reached 10 years without relapse subsequently developed recurrence. Survival and freedom from relapse (FFR) were significantly worse for older patients. Relapse rates were lower following treatment on both sides of the diaphragm or staging laparotomy. Univariate analysis showed that youth and staging laparotomy were associated with significantly better survival and that FFR was better following treatment on both sides of the diaphragm or laparotomy. CONCLUSION: Radiotherapy remains the treatment of choice for early-stage low-grade follicular lymphomas. Patients who have remained free of disease for 10 years are unlikely to relapse.

Clinical stage IA (limited patch and plaque) mycosis fungoides. A long-term outcome analysis.

OBJECTIVES: To study the long-term results of treatment of patients with stage IA mycosis fungoides and analyze the factors related to disease progression and the effect of initial therapy on survival and freedom from relapse. DESIGN: A single-center, 32(1/2)-year, retrospective cohort analysis. SETTING: Private referral medical center. PATIENTS: One hundred twenty-two patients with clinical stage IA (T1, N0, M0) mycosis fungoides. MAIN OUTCOME MEASURES: Long-term actuarial survival and freedom-from-relapse results as calculated by the technique of Kaplan-Meier. RESULTS: The long-term (30-year) survival of patients with stage IA mycosis fungoides is similar to the expected survival of a race-, age-, and sex-matched control population. The median survival of this group has not been reached at 32(1/2)-years. Eleven patients (9%) who progressed to more advanced disease had a lower complete response rate to initial therapy than did other patients (36% vs 82%) and an older mean age than did other patients with T1 disease (61 vs 48 years, P < .05). Only 3 (2%) of 122 patients died of disease. Among stage IA patients who achieved a complete response, 25% are relapse free at 10 years. Patients who received total skin electron beam therapy (n = 34) had a more favorable freedom-from-relapse outcome than those treated with topical mechlorethamine hydrochloride (nitrogen mustard) (n = 73, P < .05). No significant difference was seen in the long-term survival between the 2 treatment groups. CONCLUSIONS: Patients with clinical stage IA mycosis fungoides treated at Stanford University do not have an altered life expectancy. Fewer than 10% progressed to more advanced stages and few died of disease. Although the response rate to total skin electron beam therapy was superior to that of topical mechlorethamine, the longterm survival results were similar. Topical mechlorethamine is a cost-effective and convenient therapy for patients with limited patch and plaque mycosis fungoides.

Influence of preparatory regimen and source of hematopoietic cells on outcome of autotransplantation for non-Hodgkin's lymphoma.

The use of high-dose chemotherapy with or without total-body irradiation (TBI) followed by autologous hematopoietic cell transplantation is associated with improved survival for relapsed or refractory non-Hodgkin's lymphoma (NHL). Previous reports comparing preparatory regimens with or without TBI followed by autologous bone marrow transplantation (ABMT) or peripheral blood progenitor cell transplantation (PBPCT) for these patients did not demonstrate any survival difference between the different modalities. No randomized studies comparing survival for patients with NHL transplanted with radiochemotherapy vs. chemotherapy alone have been reported. We treated 221 patients with high-risk, relapsed or refractory NHL with either chemotherapy alone or radiochemotherapy followed by ABMT or PBPCT. The patients were assigned preparatory regimens in a non-randomized manner and this analysis was performed to evaluate differences in outcome with the two preparatory regimens. Actuarial five-year event-free survival (EFS) was similar in patients receiving fractionated total-body irradiation (FTBI) plus etoposide (VP-16) and cyclophosphamide (Cy) compared with chemotherapy alone consisting of carmustine (BCNU) plus identical doses of VP-16 and Cy (52% vs. 46%, p = 0.08). Overall survival (OS) favored radiochemotherapy (61%) compared with chemotherapy alone (53%, p = 0.02). The relapse rate was the same in both groups (41%), whereas the transplantation-related mortality (TRM) was similar in patients receiving chemotherapy alone and those receiving radiochemotherapy (13% vs. 7% respectively, p = 0.30). Proportional hazards analysis of significant variables including preparatory regimen found only the number of prior relapses to be predictive of EFS. Fewer number of prior relapses, radiochemotherapy and PBPCT were significant predictors of favorable OS. In additional analyses, the improved OS of the radiochemotherapy regimen was confirmed only for patients receiving ABMT but was not a significant predictor of outcome in patients transplanted with PBPCT. From these retrospective data we conclude: 1) PBPCT resulted in survival superior to that of ABMT; 2) the risk of relapse is similar with either preparatory regimen; 3) patients with fewer prior relapses enjoyed superior overall and event-free survival as well as fewer relapses; and 4) there were no significant differences in the two preparatory regimens when combined with PBPCT in relapsed or refractory NHL.

Multiple courses of high-dose total skin electron beam therapy in the management of mycosis fungoides.

PURPOSE: A retrospective analysis was undertaken to determine the indications for, the efficacy of, and the long-term complications of two courses of total skin electron beam therapy for mycosis fungoides. METHODS AND MATERIALS: A retrospective analysis of 15 patients with the pathologic diagnosis of mycosis fungoides treated in the Department of Radiation Oncology at Stanford University Medical Center between 1968 and 1990 was performed. All patients received two courses of high-dose electron beam therapy to the skin. The mean dose for the total skin treatment for the first course was 32.6 Gy and 23.4 Gy for the second course of treatment. RESULTS: Following the first course of total skin electron beam therapy, 11 of 15 had a complete response, with a mean duration of 11.6 months. All patients received adjuvant therapies between the first and second courses of high-dose total skin electron beam therapy. The mean interval between the first and the second courses of therapy was 41.3 months. Patients were restaged prior to commencement of their second course of high-dose total skin electron beam therapy, resulting in upstaging in six. The second course of therapy resulted in six complete responses and nine partial responses. Twelve of these patients have since died, 1 is lost to follow-up, and 2 are living with disease. The long-term side effects in the two living patients include pigmentation changes, alopecia, and diffuse xerosis. CONCLUSION: Delivery of two courses of total skin electron beam therapy is technically feasible, tolerable, and efficacious. The dose to the total skin was reduced for the second course of therapy in all cases. The criteria used to screen patients included initial good response to total skin electron treatment, long disease-free interval, exhaustion of other therapeutic modalities, and generalized skin involvement at relapse. Long-term toxicities were mild in severity and generally consisted of generalized xerosis, scattered telangiectasias, pigmentation changes, and partial alopecia.

Pelvic relapse following subtotal lymphoid irradiation in early stage Hodgkin's disease--an analysis of risk, management, and outcome.

PURPOSE: To evaluate the time of onset, method of identification, management, and outcome of pelvic relapse following subtotal lymphoid irradiation (STLI) alone (mantle and paraaortic/spleen or splenic pedicle fields, excluding the pelvis) in supradiaphragmatic Stage I-II Hodgkin's disease. METHODS AND MATERIALS: A retrospective analysis was performed of the initial, relapse, and regular follow-up evaluations of patients with pelvic relapse following STLI alone from 1968 to the present for supradiaphragmatic Stage I-II Hodgkin's disease after pathologic staging (PS-laparotomy staging) and clinical staging (CS-no laparotomy staging). RESULTS: Following staging, which included bipedal lymphangiography, 482 patients (408 PS and 74 CS), were treated with STLI alone for supradiaphragmatic Stage I-II Hodgkin's disease. The actuarial freedom from relapse at 20 years was 75% in PS patients and 81% in CS patients. The actuarial pelvic failure at 20 years was 7% for PS patients and 3% for CS patients. Of the 29 patients with pelvic relapse, 97% (28 of 29) occurred within 5 years of treatment, including 1 patient who progressed during initial treatment. Pelvic relapse was most commonly initially identified by abnormalities involving patient symptoms (62%), physical examination (55%), erythrocyte sedimentation rate (48%), and bipedal lymphangiogram and/or abdominal radiograph (38%). Relapse was limited to previously unirradiated sites in 17 patients (58%). In addition to pelvic lymph node disease, 3 patients (10%) had involvement of bone, and 4 patients (14%) had bone marrow involvement. Following relapse, all patients were treated with chemotherapy (MOP[P], MOP[P]/ABV[D], ABVD, or PAVe) and 19 of 29 patients received involved field consolidative irradiation. Twenty-one of 29 (72%) remained relapse free at the time of last follow-up evaluation, including 15 of 19 (79%) treated with combined therapy. Eight patients experienced a second relapse despite salvage therapy, and all eight expired with recurrent Hodgkin's disease. Two patients died of complications related to prior treatment. Therefore, the actuarial risk of death at 20 years associated with pelvic failure in the entire cohort of 482 patients was 2%. CONCLUSION: Pelvic relapse occurred in 7% of patients following STLI alone and was effectively diagnosed by regular follow-up, which included a combination of patient history, physical examination, and radiographic laboratory evaluation. Seventy-two percent of patients remained relapse free following salvage treatment, which included chemotherapy, resulting in an overall survival rate associated with pelvic control of 98%. This approach, therefore, spared the majority of patients the long-term risks associated with pelvic irradiation and/or chemotherapy, such as infertility, but maintained an excellent prognosis.

CD8-positive tumor-infiltrating lymphocytes influence the long-term survival of patients with mycosis fungoides.

BACKGROUND: Nonneoplastic mononuclear cells commonly infiltrate lesions of mycosis fungoides. OBJECTIVE: We sought to determine the immunophenotypic characteristics of these cells and to determine whether the presence of CD8+ tumor-infiltrating lymphocytes has an impact on prognosis. METHODS: Skin biopsy specimens from 78 patients were stained with immunopleroxidase techniques to determine their phenotypic characteristics. The proportion of CD8+ tumor-infiltrating lymphocytes was quantified and compared with stage of disease and survival rate. RESULTS: Patients with more limited T-stage disease tended to have a higher proportion of CD8+ cells in their skin biopsy specimens, compared with patients with more advanced T-stage disease. Within each T-stage patients with a larger proportion of CD8+ cells had a better survival rate than those with fewer CD8+ cells (p < 0.05 for T1 and T3). A multivariate analysis confirmed the importance of T stage (p = 0.0006), overall stage (p = 0.0112), and CD8 positivity (p = 0.0335) in this cohort of patients. CONCLUSION: CD8+ tumor-infiltrating lymphocytes in mycosis fungoides correlate with improved survival rate and may exert an antitumor effect rather than being mere bystander cells.

Brief chemotherapy, Stanford V, and adjuvant radiotherapy for bulky or advanced-stage Hodgkin's disease: a preliminary report.

PURPOSE: Although survival rates have improved for patients with bulky and advanced-stage Hodgkin's disease (HD), current treatments entail substantial acute morbidity and risks for late effects such as infertility, second malignancies, and cardiopulmonary toxicities. A novel, brief chemotherapy regimen (doxorubicin, vinblastine, mechlorethamine, vincristine, bleomycin, etoposide, and prednisone [Stanford V]) was designed to shorten the duration of treatment, significantly reduce cumulative doses of alkylating agents, doxorubicin, and bleomycin, and maintain dose-intensity (DI). This brief chemotherapy was combined with radiation therapy (RT) to bulky disease sites. METHODS: Since May 1989, 65 previously untreated patients were treated for stage II HD with bulky mediastinal involvement (n = 21) or for stage III or IV HD (n = 44). Patients received weekly chemotherapy for 12 weeks. Consolidative RT was given to the first 25 patients to sites of initial bulky disease or radiographic abnormalities that persisted after chemotherapy; in the remaining 40 patients, RT was limited to bulky disease (adenopathy > or = 5 cm and/or macroscopic splenic nodules defined by computed tomography [CT]). RESULTS: With a median follow-up period of 2 years, actuarial 3-year survival rate is 96% and failure-free survival (FFS) rate is 87%. The 3-year FFS rate is 100% for stage II patients with bulky mediastinal disease and 82% for patients with stage III to IV disease. There were no treatment-related deaths. In a preliminary analysis on a subset of patients, female and male fertility appears to be preserved. CONCLUSION: These preliminary results indicate that the Stanford V chemotherapy regimen with or without RT is well-tolerated and effective therapy for bulky, limited-stage, and advanced-stage HD. Less cumulative exposure to alkylating agents, doxorubicin, and bleomycin and limited use of radiation is expected to decrease risks for second neoplasms and late cardiopulmonary toxicity. Based on these results, the Stanford V chemotherapy with or without RT regimen deserves further study in the context of a randomized clinical trial.

Prognostic factors in erythrodermic mycosis fungoides and the Sézary syndrome.

BACKGROUND AND DESIGN: There are no large studies evaluating patients with erythrodermic mycosis fungoides and Sézary syndrome to determine the important prognostic factors that may influence survival. This is important since new treatment modalities have been proposed as superior to existing primary therapies. We performed a retrospective cohort study of 106 patients with erythrodermic mycosis fungoides and Sézary syndrome, followed up in the Stanford (Calif) Mycosis Fungoides Clinic, to define the important prognostic factors in this group. RESULTS: Patients younger than 65 years have a more favorable survival profile than those 65 years or older (P < .005). Longer duration of symptoms before diagnosis ( > or = 10 years) tends to be associated with more favorable prognosis (p = .055). Lymph node stage is significantly correlated with survival; patients with overall stage III disease have more favorable prognosis than those with stage IV disease (P < .001). Patients with circulating Sézary cells in their blood have a significantly worse prognosis than those without (P < .005). Patient sex or race had no significant effect on overall survival outcome. Three distinct prognostic groups were identified, "favorable," "intermediate," and "unfavorable," according to the number of unfavorable prognostic factors (P < .005). The median survival in each group is 10.2, 3.7, and 1.5 years, respectively. CONCLUSIONS: In patients with erythrodermic mycosis fungoides and Sézary syndrome, the important prognostic factors are patient age at presentation, the overall stage, and peripheral blood involvement. Survival varies widely, depending on these variables. These prognostic factors should be evaluated when analyzing survival and/or treatment efficacy data of these patients.

Electron beam treatment for cutaneous T-cell lymphoma.

Total skin electron radiation has proven efficacy in treating MF. It is a complex technique that requires a dedicated radiation team, involving physicists, radiotherapists, and radiation oncologists. A center must treat a sufficiently high volume of patients to justify the development of TSE, with appropriate organization, time, and expense. The radiation team should be an integral part of a multidisciplinary clinical group, including medical oncologists, dermatologists, pathologists, and nurses. In these contexts, TSE has appropriately been developed in a limited number of centers. Cooperation between these centers is essential for further refinement of TSE techniques and for evolution of the role of TSE in the management of most patients with MF.

Progress in the treatment of Hodgkin's disease in the United States, 1973 versus 1983. The Patterns of Care Study.

BACKGROUND: The prognosis for Hodgkin's disease patients has improved significantly since the early 1960s. The reasons for this improvement are multifactorial. METHODS: In the Patterns of Care Study of the American College of Radiology, national surveys to examine process and outcome of patients treated for Hodgkin's disease in 1973 and 1983 were completed. Data were compared for patients who had Stage I-II Hodgkin's disease and who were treated with radiation therapy alone. RESULTS: Clinical characteristics of the patients in the two different treatment eras were similar. There were important differences in treatment parameters. In 1983 compared with 1973, there was more common use of a dedicated simulator, performance of routine port films, use of linear accelerators, use of individually shaped blocks, and treatment to extended fields. Adequacy of treatment fields also was judged superior in the 1983 study. There were improvements in survival and relapse-free survival for patients treated in 1983 versus 1973. CONCLUSIONS: Improvement in radiation therapy technique is associated with an improved outcome for patients treated for Hodgkin's disease. The national standards have improved during the time from 1973 to 1983.

Effect of filgrastim (G-CSF) in Hodgkin's disease patients treated with radiation therapy.

PURPOSE: To evaluate the effect of filgrastim (recombinant human G-CSF) on radiation-induced neutropenia in a well defined, homogenous patient population. METHODS AND MATERIALS: Seven patients who were to receive large field subdiaphragmatic irradiation after thoracic "mantle" fields for treatment of Hodgkin's disease entered this study. They received daily subcutaneous (SC) injections of filgrastim during subdiaphragmatic irradiation. Total white blood cell (WBC) and absolute neutrophil cell (ANC) counts were measured and compared to a historical series of patients, and hematological toxicity was assessed. The endpoints of the study were nadir WBC and ANC counts and time to WBC and ANC recovery. RESULTS: Compared to the historical series, filgrastim significantly increased the WBC and ANC throughout the period of subdiaphragmatic irradiation. Nadir WBC (5.98 +/- 1.24/mm3) and ANC (4.71 +/- 1.07/mm3) in the Filgrastim group were approximately two times those of the historical series (3.32 +/- 1.06/mm3 and 2.39 +/- 0.97/mm3 respectively; p < 0.002). Nadir platelet counts were not affected by filgrastim therapy. Three of seven patients reported mild musculoskeletal pain, but there was no other apparent toxicity. CONCLUSION: Compared to the historical series, filgrastim therapy significantly increased WBC and ANC during extended field radiation therapy and was well tolerated. It may be clinically useful in other groups of patients who are likely to develop profound neutropenia during large field irradiation.

Treatment of early-stage gastric lymphoma.

The treatment of early-stage gastric lymphoma is controversial. This retrospective analysis reports on the outcome of 24 patients treated in our institution during the past 25 years. Fourteen patients had stage IEA, one patient had IEB, six patients IIEA1, and three patients had stage IIEA2 non-Hodgkin's lymphoma (NHL). Diffuse large cell intermediate-grade NHL was diagnosed in 17 patients, diffuse small cleaved cell in three patients, and diffuse mixed large and small cell lymphosarcoma, low-grade B-cell lymphoma, and unclassified lymphoma in one patient each. Fourteen patients underwent surgery, 21 had radiation therapy (XRT), and 10 patients received chemotherapy. Surgery + XRT were given to 7 patients, surgery + XRT + chemo and XRT alone were delivered to five patients each, and XRT + chemotherapy were employed in four patients. Surgery alone was the initial treatment in two patients and chemotherapy alone was given to one patient. Following treatment 22/24 achieved a complete response. During a mean follow-up period of 77.6 months (range 1-285), five patients relapsed. At 10 years, the actuarial survival of the 15 patients with stage I disease was 57.4% and for stage II it was 51.9% (Gehan P-value 0.33). Freedom from relapse (FFR) was 60.7% and 58.3%, respectively (P-value 0.56). No significant statistical differences in terms of survival and FFR were noted in patients treated with surgery, chemotherapy, or XRT. The outcome of patients treated with triple-modality therapy was similar to those treated with double-modality therapy and to patients treated with XRT alone. Gender, age, presenting symptoms, depth of tumor through the gastric wall, and stage were not statistically significant for prediction of either survival or FFR. Both surgery + XRT and chemotherapy + XRT are effective in the treatment of early-stage gastric disease. XRT alone is equally effective as two or three modality treatments in the subset of patients with early-stage gastric lymphoma. However, the low number of patients treated with various approaches over a long period precludes a firm conclusion. Until prospective randomized studies are initiated, management programs should be individually tailored.

Expression of class II major histocompatibility antigens by keratinocytes in cutaneous T cell lymphoma.

BACKGROUND: Expression of various class II MHC antigens by lesional keratinocytes may play an important role in the pathophysiology of a wide variety of human dermatoses including cutaneous T cell lymphoma (CTCL). Nevertheless, there is relatively little information available concerning the concurrent expression of HLA-DR, -DP, and -DQ class II MHC antigens in CTCL. Therefore, our aim in this study was to determine the prevalence, localization, extent, temporal sequence, and consistency of class II MHC antigen expression by lesional keratinocytes in CTCL. METHODS: We used a semiquantitative immunohistologic analysis to analyze HLA-DR, -DP, and -DQ expression by lesional keratinocytes in 66 skin biopsies obtained from 39 patients with CTCL. RESULTS: Class II MHC antigen expression by keratinocytes was observed in 77% of cases. Expression was detected on the cytoplasmic membrane and within the cytoplasm. It varied among cases from focal to confluent. There was a hierarchy of antigen expression in terms of both extent and time course. HLA-DR was expressed first and most extensively, followed by HLA-DP and then HLA-DQ. Comparative studies of multiple serial or concurrent active lesions from 13 cases indicated that the overall pattern and extent of antigen expression was relatively constant within individual patients. CONCLUSIONS: There was no apparent correlation between class II MHC antigen expression and the clinical stage of disease, the type of CTCL skin lesion, or the overall density of the lesional T cell infiltrate. The hierarchy of keratinocyte class II MHC antigen expression observed in this study paralleled that noted in earlier studies of cultured keratinocytes exposed to recombinant interferon-gamma in vitro. This suggests that lesional cytokine levels may be the critical factor governing class II MHC antigen expression by lesional keratinocytes in CTCL.

Mycosis fungoides skin lesions contain CD8+ tumor-infiltrating lymphocytes expressing an activated, MHC-restricted cytotoxic T-lymphocyte phenotype.

In prior studies, we showed that most CD8+ cells infiltrating skin lesions of CD3+CD4+ mycosis fungoides were CD3+ T-lineage tumor-infiltrating lymphocytes (TIL) whose overall phenotype was suggestive of MHC-restricted cytotoxic T lymphocytes (CTL). However, their lack of cytotoxic-associated granzyme A mRNA suggested that they might be unactivated CTL precursors. In this study, we used single- and double-label immunohistologic techniques to assess the expression of TIA-1-reactive protein and HLA-DR by these CD8+TIL. Monoclonal antibody TIA-1 recognizes a novel family of proteins expressed preferentially by cytotoxic cells, including some that lack granzyme A. HLA-DR is a marker of T-cell activation. Single-label studies of 32 cases showed that CD8+TIL and TIA-1+ cells constituted a variable minority of the total cellular infiltrate and had a similar distribution. Double-label studies of 14 cases showed that in most instances the aggregate phenotype of the majority of CD8+TIL was CD3+TIA-1+HLA-DR+CD56-CD57-. These findings suggest that many of the CD8+TIL within skin lesions of CD3+CD4+ mycosis fungoides are activated, MHC-restricted CTL.

Fractionated total-body irradiation, etoposide, and cyclophosphamide plus autografting in Hodgkin's disease and non-Hodgkin's lymphoma.

PURPOSE: High-dose etoposide was incorporated into a regimen of fractionated total-body irradiation (FTBI) and high-dose cyclophosphamide before autologous transplant with the goal to enhance the antitumor effect of the myeloablative regimen in poor-risk lymphoid malignancies. PATIENTS AND METHODS: Ninety-six patients, 24 with recurrent or refractory Hodgkin's disease and 72 with poor-risk non-Hodgkin's lymphoma (NHL), were treated on this study. Cytoreduction with conventional therapy was attempted before administration of the preparatory regimen. The preparatory regimen consisted of 12 Gy total-body irradiation administered in 10 1.2-Gy fractions on day -8 through day -5, etoposide 60 mg/kg on day -4, and cyclophosphamide 100 mg/kg on day -2. Patients with NHL received bone marrow purged with a panel of monoclonal antibodies and complement on day 0, while patients with Hodgkin's disease received peripheral-blood stem cells alone or with unmanipulated bone marrow. RESULTS: The major morbidities of transplant were mucositis and skin toxicity. Eight patients (8.6%) died of regimen-related toxicities within 100 days of transplant. Engraftment was related to the rescue product; the median time to a neutrophil count more than 500/microL was 10 days for patients with Hodgkin's disease and 16 days for NHL patients. With a maximum follow-up duration of longer than 5 years, the 3-year actuarial survival rate is 57%. At 3 years, the actuarial freedom from progression (FFP) rate is 55% and the event-free survival rate is 47% for patients with Hodgkin's disease, while the respective figures for NHL patients are 60% and 53%. Among 32 patients with intermediate- and high-grade lymphoma transplanted subsequent to first relapse, 70% are free of lymphoma and 60% are event-free at > or = 3 years. CONCLUSION: The preparatory regimen consisting of FTBI, etoposide, and cyclophosphamide demonstrates relative efficacy in patients with Hodgkin's disease and NHL selected for high-dose therapy. Longer follow-up duration is needed to determine the rate of cure and to assess late complications. Major remaining challenges for high-dose therapy are a more inclusive strategy for all poor-risk patients and the need to reduce posttransplant relapses.

Effect of treatment for Hodgkin's disease on pulmonary function: results of a prospective study.

PURPOSE: Because each of very different treatments for Hodgkin's disease (HD) may result in a high rate of cure, attention is currently focused on toxicity. This prospective study was designed to assess the effects of mediastinal irradiation and bleomycin chemotherapy on pulmonary function. PATIENTS AND METHODS: Patients were treated from 1980 to 1990 on randomized controlled trials at Stanford University. Pulmonary function was tested before treatment (baseline), early after treatment (< 15 months), and more than 36 months posttherapy. Treatment options in the 145 patients were grouped as I (mediastinal radiotherapy), II (mediastinal radiotherapy plus bleomycin), and III (bleomycin) for analyses of variance (ANOVAs). A variety of regression models were used to predict early and late effects on pulmonary function. RESULTS: A decrease in forced vital capacity (FVC) and diffusing capacity (DLCO) in the first 15 months after treatment followed by recovery after 36 months was observed for most patients. Patients who received mediastinal radiotherapy (RT) had a more pronounced reduction in pulmonary function and less complete recovery. Overall, 3 or more years after treatment, 32% of group I patients, 37% of group II patients, and 19% of group III patients had FVC values less than 80% of predicted, while only 7% of patients had a DLCO less than 80% of predicted. Linear regression identified baseline measurement as the only significant predictor of change in percent predicted FVC or DLCO; patients with higher baseline values had greater decrements after therapy. Mantle RT was the only significant treatment variable, predictive of FVC and DLCO within 15 months and FVC at 36 or more months. No patient experienced pulmonary toxicity severe enough to require hospitalization. CONCLUSION: This prospective analysis of pulmonary function after treatment for HD showed that mediastinal RT was the only treatment variable that achieved statistical significance. Although there were no significant interactions between mediastinal RT and bleomycin or Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH) chemotherapy, the patient numbers were small after correction for mediastinal mass size and drug regimen such that an effect could have been missed. The mild reduction in pulmonary function should be factored into the overall assessment of morbidity risk for each of the potentially curative treatments included in this study. As with all reports of late effects, these data should be interpreted with respect to the population tested, details of the treatment administered, methods of measurement, and length of follow-up.

Factors affecting late mortality from heart disease after treatment of Hodgkin's disease.

OBJECTIVE: To assess the risk of death from heart disease after Hodgkin's disease therapy. DESIGN: Retrospective study comparing treated patients with a matched general population. SETTING: Referral center. PATIENTS: A total of 2232 consecutive Hodgkin's disease patients treated from 1960 through 1991. Follow-up averaged 9.5 years. MAIN OUTCOME MEASURES: Relative risks (RRs), the ratio of the observed to the expected cases with 95% confidence intervals (CIs), chi tests for trends, and Kaplan-Meier actuarial risks. RESULTS: Of the 2232 patients, 88 (3.9%) died of heart disease, 55 from acute myocardial infarction and 33 from other cardiac diseases, including congestive heart failure, radiation pericarditis or pancarditis, cardiomyopathy, or valvular heart disease. The RR for cardiac death was 3.1 (CI, 2.4 to 3.7). Mediastinal radiation of 30 Gy or less (n = 385 patients) did not increase risk; above 30 Gy (n = 1830), RR was 3.5 (CI, 2.7 to 4.3). Blocking to limit cardiac exposure reduced the RR for other cardiac diseases from 5.3 (CI, 3.1 to 7.5) to 1.4 (CI, 0.6 to 2.9), but not acute myocardial infarction (RR, 3.7 vs 3.4). The RRs increased with duration after treatment (trend in acute myocardial infarction, P = .02; in other cardiac diseases, P = .004). The RR for acute myocardial infarction was highest after irradiation before 20 years of age and decreased with increasing age at treatment (P < .0001 for trend). CONCLUSIONS: Mediastinal irradiation for Hodgkin's disease increases the risk of subsequent death from heart disease. Risk increased with high mediastinal doses, minimal protective cardiac blocking, young age at irradiation, and increasing duration of follow-up.
