Combined-modality therapy for clinical stage I or II Hodgkin's lymphoma: long-term results of the European Organisation for Research and Treatment of Cancer H7 randomized controlled trials.

PURPOSE: In early-stage Hodgkin's lymphoma (HL), subtotal nodal irradiation (STNI) and combined chemotherapy/radiotherapy produce high disease control rates but also considerable late toxicity. The aim of this study was to reduce this toxicity using a combination of low-intensity chemotherapy and involved-field radiotherapy (IF-RT) without jeopardizing disease control. PATIENTS AND METHODS: Patients with stage I or II HL were stratified into two groups, favorable and unfavorable, based on the following four prognostic factors: age, symptoms, number of involved areas, and mediastinal-thoracic ratio. The experimental therapy consisted of six cycles of epirubicin, bleomycin, vinblastine, and prednisone (EBVP) followed by IF-RT. It was randomly compared, in favorable patients, to STNI and, in unfavorable patients, to six cycles of mechlorethamine, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, and vinblastine (MOPP/ABV hybrid) and IF-RT. RESULTS: Median follow-up time of the 722 patients included was 9 years. In 333 favorable patients, the 10-year event-free survival rates (EFS) were 88% in the EBVP arm and 78% in the STNI arm (P = .0113), with similar 10-year overall survival (OS) rates (92% v 92%, respectively; P = .79). In 389 unfavorable patients, the 10-year EFS rate was 88% in the MOPP/ABV arm compared with 68% in the EBVP arm (P < .001), leading to 10-year OS rates of 87% and 79%, respectively (P = .0175). CONCLUSION: A treatment strategy for early-stage HL based on prognostic factors leads to high OS rates in both favorable and unfavorable patients. In favorable patients, the combination of EBVP and IF-RT can replace STNI as standard treatment. In unfavorable patients, EBVP is significantly less efficient than MOPP/ABV.

Phase III intergroup study of fludarabine phosphate compared with cyclophosphamide, vincristine, and prednisone chemotherapy in newly diagnosed patients with stage III and IV low-grade malignant Non-Hodgkin's lymphoma.

PURPOSE: To compare the efficacy and safety of fludarabine phosphate with cyclophosphamide, vincristine, and prednisone (CVP) in 381 previously untreated, advanced-stage, low-grade (lg) non-Hodgkin's lymphoma (NHL) patients in a phase III, multicenter study. PATIENTS AND METHODS: Between 1993 and 1997, patients were randomly assigned to treatment with either fludarabine (25 mg/m2 intravenously [IV] daily for 5 days every 4 weeks) or CVP (cyclophosphamide 750 mg/m2 IV on day 1; vincristine, 1.4 mg/m2 IV on day 1; and prednisone, 40 mg/m2 orally on days 1 through 5 every 4 weeks). Results Overall response (OR) rates were significantly improved in the fludarabine arm versus the CVP arm, both for the intent-to-treat (ITT) population and assessable patients (P < .001). Complete response (CR) rates in the ITT population were also higher after fludarabine treatment. The CR rate was 38.6% for fludarabine compared with 15.0% for CVP. There were no statistically significant differences in time to progression (TTP), time to treatment failure (TTF), and overall survival (OS) between treatment groups. WHO grades 3 and 4 hematologic adverse events were more common in the fludarabine arm. However, concerning the higher incidence of granulocytopenia, this did not translate to more infections in fludarabine-treated patients. CONCLUSION: Newly diagnosed lgNHL patients who received fludarabine achieved higher OR and CR rates compared with CVP-treated patients. No differences in TTP, TTF, and OS were noted. Fludarabine is a highly active single agent in lgNHL. Combination therapies incorporating fludarabine are now being further evaluated as first-line therapy in follicular NHL.

Aggressive non-Hodgkin's lymphoma: concomitant evaluation of interleukin-2, soluble interleukin-2 receptor, interleukin-4, interleukin-6, interleukin-10 and correlation with outcome.

The purpose of this study was to assess the prognostic value of a large panel of cytokines in aggressive non-Hodgkin's lymphoma (NHL) and to confront it to parameters of the International Prognostic Index (IPI). It investigated the concomitant determination of interleukin-2 (IL-2), soluble interleukin-2 receptor (sIL-2R), interleukin-4 (IL-4), interleukin-6 (IL-6) and interleukin-10 (IL-10) on a uniform population of 116 previously untreated patients. Commercially available enzyme-linked immunoassay kits were used for cytokines measurements. Results were correlated with complete remission (CR), overall survival (OS) and failure free survival (FFS). In univariate analysis, sIL-2R and IL-6 demonstrated prognostic significance for CR (p = 0.016 and p = 0.048), OS (p = 0.0011 and p = 0.0387) and FFS (p = 0.0001 and p = 0.0363), but multi-variate analysis failed to demonstrate an independent prognostic significance. In the intermediate group risk defined by IPI, patients presenting high level of sIL-2R or IL-6 demonstrated lower CR rate and survival than those with low level. In conclusion, sIL-2R and IL-6 serum levels are elevated in high grade NHL and are correlated to CR, OS and FFS, but this study did not support their independent prognostic value. However, sIL-2R and IL-6 measurements may improve risk assignment by IPI and allow a better prognostic evaluation of patients with intermediate prognosis NHL.

Fludarabine phosphate-CVP in patients over 60 years of age with advanced, low-grade and follicular lymphoma: a dose-finding study.

The aim of this study was to establish a safe and effective regimen of fludarabine phosphate, cyclophosphamide, vincristine and prednisone (F-CVP) as first-line treatment for elderly patients with advanced, low-grade non-Hodgkin's lymphoma. Twenty-three patients >60 years were assigned successively to eight treatment cycles (Dose level 1: low F, low CV [n=4]; 2A: high F, low CV [n=8]; 2B: low F, high CV [n=4]; 3: high F, high CV [n=7]). High and low levels were: F, 25 and 20mg/m(2), respectively (Days 1-5); C, 750 and 500 mg/m(2), respectively (Day 1); and V, 1.4 and 1mg/m(2), respectively (Day 1). Patients received P at 40 mg/m(2) on Days 1-5. Response was assessed after Cycles 2, 4, 6 and 8. At level 3, dose-limiting toxicity (opportunistic infections and neutropenia) became evident, particularly after Cycle 6. Further patients were recruited at Dose level 2A. All regimens proved effective, with an OR rate of 78% (65% CR), and 3-year survival of 65% (+/-10%). Among 18 responders, 51% were still in response at 3 and 5 years. The study shows that this combination therapy is highly effective. The addition of F to CVP at Dose level 2A was feasible and increased the CR rate, with good tolerability in elderly patients.

Dexamethasone-based regimens versus melphalan-prednisone for elderly multiple myeloma patients ineligible for high-dose therapy.

Dexamethasone alone increases life expectancy in patients with relapsed multiple myeloma (MM); however, no large randomized study has compared dexamethasone and dexamethasone-based regimens with standard melphalan-prednisone in newly diagnosed MM patients ineligible for high-dose therapy. In the Intergroupe Francophone du Myélome (IFM) 95-01 trial, 488 patients aged 65 to 75 years were randomized between 4 regimens of treatment: melphalan-prednisone, dexamethasone alone, melphalan-dexamethasone, and dexamethasone-interferon alpha. Response rates at 6 months (except for complete response) were significantly higher among patients receiving melphalan-dexamethasone, and progression-free survival was significantly better among patients receiving melphalan (P < .001, for both comparisons), but there was no difference in overall survival between the 4 treatment groups. Moreover, the morbidity associated with dexamethasone-based regimens was significantly higher than with melphalan-prednisone, especially for severe pyogenic infections in the melphalan-dexamethasone arm and hemorrhage, severe diabetes, and gastrointestinal and psychiatric complications in the dexamethasone arms. Overall, these results indicated that dexamethasone should not be routinely recommended as first-line treatment in elderly patients with MM. In the context of the IFM 95-01 trial, the standard melphalan-prednisone remained the best treatment choice when efficacy and patient comfort were both considered. These results might be useful in the context of future combinations with innovative drugs.

Quality control of involved-field radiotherapy in patients with advanced Hodgkin's lymphoma (EORTC 20884).

PURPOSE: To evaluate the impact of the quality of involved-field radiotherapy (IFRT) on clinical outcome in patients with advanced Hodgkin's lymphoma (HL) in complete remission (CR) after six to eight cycles of mechlorethamine, vincristine, procarbazine, prednisone-doxorubicin, bleomycin, and vinblastine (MOPP-ABV) chemotherapy. METHODS AND MATERIALS: A retrospective review of clinical and radiologic data, radiation charts, simulator films, and megavoltage (MV) photographs was performed. IFRT consisted of 24 Gy to all initially involved nodal areas and 16-24 Gy to all initially involved extranodal sites. Major violations were defined as no or only partial irradiation of an originally involved area, or a total dose <90% of the prescribed dose. RESULTS: Of the 739 patients who were enrolled in the trial between 1989 and 2000, 57% achieved a CR; 152 of 172 patients randomized to IFRT actually received radiotherapy; and in 135 patients, quality control was performed. The overall major violation rate was 47%, predominantly concerning target volumes. The total dose was correct in 81% of the patients. After a median follow-up of 6.5 years, there was no difference in cumulative failure rate between patients with or without major violations. There was no relationship between incidence or site of relapse and major protocol violations. CONCLUSION: In advanced-stage HL patients in complete remission after six to eight cycles of MOPP-ABV, the outcome was not influenced by violation of the radiotherapy protocol.

Involved-field radiotherapy for advanced Hodgkin's lymphoma.

BACKGROUND: The use of involved-field radiotherapy after chemotherapy for advanced Hodgkin's lymphoma is controversial. METHODS: We randomly assigned patients with previously untreated stage III or IV Hodgkin's lymphoma who were in complete remission after hybrid chemotherapy with mechlorethamine, vincristine, procarbazine, prednisone, doxorubicin, bleomycin, and vinblastine (MOPP-ABV) to receive either no further treatment or involved-field radiotherapy. Radiotherapy consisted of 24 Gy to all initially involved nodal areas and 16 to 24 Gy to all initially involved extranodal sites. Patients in partial remission were treated with 30 Gy to nodal areas and 18 to 24 Gy to extranodal sites. RESULTS: Of 739 patients, 421 had a complete remission; 161 of these patients were assigned to no further treatment, and 172 to involved-field radiotherapy. The median follow-up was 79 months. The five-year event-free survival rate was 84 percent in the group that did not receive radiotherapy and 79 percent in the group that received involved-field radiotherapy (P=0.35). The five-year overall survival rates were 91 and 85 percent, respectively (P=0.07). Among the 250 patients in partial remission after chemotherapy, the five-year event-free and overall survival rates were 79 and 87 percent, respectively. CONCLUSIONS: Involved-field radiotherapy did not improve the outcome in patients with advanced-stage Hodgkin's lymphoma who had a complete remission after MOPP-ABV chemotherapy. Radiotherapy may benefit patients with a partial response after chemotherapy.

Quality of life in patients with aggressive non-Hodgkin's lymphoma. Validation of the medical outcomes study short form 20 and the Rotterdam symptom checklist in older patients.

In the elderly population, cancer treatment aims to cure and/or maintain Quality of Life (QoL). However, there is little QoL data to provide evidence for QoL benefits for some of the cancer treatments. This pilot study developed valid QoL questionnaires in French, for patients over 65 years with a diagnosis of large cell lymphoma, part of the Lymâge phase II study. They were asked to complete two questionnaires, the Medical Outcomes Study Short Form 20 (MOS SF20; generic) and the Rotterdam symptom checklist (RSCL; cancer-specific). Between June 1995 and April 1997, questionnaires were returned by 63 of 89 patients. This article reports the process undertaken to adapt the English version to a French setting, and provides the results of factor analysis, convergent and discriminant validity and reliability. Our data suggest that QoL questionnaires can be used in elderly patients. These two questionnaires are validated in French and would help us to analyse the QoL of elderly patients with the development of new treatments as done in the Lymâge study.

[Update on lymphomas].

Important progress have been recently achieved in the management of Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL). Prognostic factors are now better defined in HD thanks to new biologic and radiologic information which complete old and relevant clinical factors. These parameters are expected to improve decision making in patient's management. However, treatment strategy is under new discussion and controversies about the role of radiotherapy and its doses. There are now enough arguments to consider radiotherapy unnecessary in advanced stages when a complete remission is achieved by chemotherapy. There is also important concern about late effects of treatment and not only secondary cancers. Non-Hodgkin's lymphomas are heterogeneous and different entities are now better defined and described, thanks to a common and similar language for immunological clinical data and treatment outcome. New strategies are under investigation using monoclonal antibodies with or without radioisotopes, in association with chemotherapy or radiotherapy. Undoubtedly, these new approaches are going to improve the overall prognosis of NHL.
