Second malignancy risk associated with treatment of Hodgkin's lymphoma: meta-analysis of the randomised trials.

BACKGROUND: Despite several investigations, second malignancy risks (SMR) following radiotherapy alone (RT), chemotherapy alone (CT) and combined chemoradiotherapy (CRT) for Hodgkin's lymphoma (HL) remain controversial. PATIENTS AND METHODS: We sought individual patient data from randomised trials comparing RT versus CRT, CT versus CRT, RT versus CT or involved-field (IF) versus extended-field (EF) RT for untreated HL. Overall SMR (including effects of salvage treatment) were compared using Peto's method. RESULTS: Data for between 53% and 69% of patients were obtained for the four comparisons. (i) RT versus CRT (15 trials, 3343 patients): SMR were lower with CRT than with RT as initial treatment (odds ratio (OR) = 0.78, 95% confidence interval (CI) = 0.62-0.98 and P = 0.03). (ii) CT versus CRT (16 trials, 2861 patients): SMR were marginally higher with CRT than with CT as initial treatment (OR = 1.38, CI 1.00-1.89 and P = 0.05). (iii) IF-RT versus EF-RT (19 trials, 3221 patients): no significant difference in SMR (P = 0.28) although more breast cancers occurred with EF-RT (P = 0.04 and OR = 3.25). CONCLUSIONS: Administration of CT in addition to RT as initial therapy for HL decreases overall SMR by reducing relapse and need for salvage therapy. Administration of RT additional to CT marginally increases overall SMR in advanced stages. Breast cancer risk (but not SMR in general) was substantially higher after EF-RT. Caution is needed in applying these findings to current therapies.

Autologous stem cell transplantation in multiple myeloma patients <60 vs >/=60 years of age.

The role of autologous stem cell transplantation (AuSCT) in older multiple myeloma patients is unclear. Using data from the Autologous Blood and Marrow Transplant Registry, we compared the outcome of 110 patients >/=the age of 60 (median 63; range 60-73) years, undergoing AuSCT with that of 382 patients <60 (median 52; range 30-59) years. The two groups were similar except that older patients had a higher beta(2)-microglobulin level at diagnosis (P=0.016) and fewer had lytic lesions (P=0.007). Day 100 mortality was 6% (95% confidence interval 4-9) and 1-year treatment-related mortality (TRM) was 9% (6-13) in patients <60 years, compared with 5% (2-10) and 8% (4-14), respectively, in patients >/=60 years. The relapse rate, progression-free survival (PFS) and overall survival (OS) in the two groups were also similar. Multivariate analysis of all patients identified only an interval from diagnosis to AuSCT >12 months and the use of two prior chemotherapy regimens within 6 months of AuSCT as adverse prognostic factors. Our results indicate that AuSCT can be safely performed in selected older patients: the best results were observed in patients undergoing AuSCT relatively early in their disease course.

Valacyclovir prophylaxis for the prevention of Herpes simplex virus reactivation in recipients of progenitor cells transplantation.

HSV can cause oral lesions that exacerbate chemotherapy-related mucositis. Intravenous acyclovir is effective in preventing HSV reactivations, but expensive. Valacyclovir has good bioavailability and has not been studied for prophylaxis of HSV among PCT patients. We compared the efficacy and costs of valacyclovir in preventing HSV reactivation among HSV seropositive autologous progenitor cell transplantation (APCT) patients with historical controls in whom intravenous acyclovir or no HSV prophylaxis were used. Valacyclovir group: From October 1997 to April 1999 108 adult patients received valacyclovir 500 mg twice daily from day -3 of APCT until neutropenia recovery or day +30. Valacyclovir was switched to intravenous acyclovir in cases of oral intolerance (17 patients) or suspected HSV reactivation (five patients). Intravenous acyclovir group: From January 1996 to October 1997 43 patients received 5 mg/kg twice-daily intravenous acyclovir from day -3 until recovery from neutropenia. No prophylaxis group: 38 patients from January 1996 to October 1997 did not receive HSV prophylaxis. HSV reactivations were seen in 2.7%, 2% and 45% of patients in the valacyclovir, intravenous acyclovir, and no prophylaxis groups, respectively. Valacyclovir was well tolerated and was the least expensive strategy. Oral valacyclovir was as effective as intravenous acyclovir for the prophylaxis of HSV reactivation in APCT patients.

Autologous transplantation for diffuse aggressive non-Hodgkin's lymphoma in patients never achieving remission: a report from the Autologous Blood and Marrow Transplant Registry.

PURPOSE: To evaluate the results of high-dose chemotherapy and autologous hematopoietic stem-cell transplantation (autotransplants) in patients with diffuse aggressive non-Hodgkin's lymphoma (NHL) who never achieve a complete remission with conventional chemotherapy. PATIENTS AND METHODS: Detailed records from the Autologous Blood and Marrow Transplant Registry (ABMTR) on 184 patients with diffuse aggressive NHL who never achieved a complete remission with conventional chemotherapy and subsequently received an autotransplant were evaluated. Transplants were performed between 1989 and 1995 and were reported to the ABMTR by 48 centers in North and South America. RESULTS: Seventy-nine (44%) of 184 patients achieved a complete remission or a complete remission with residual imaging abnormalities of unknown significance after autotransplantation. Thirty-four (19%) of 184 had a partial remission and 55 (31%) of 184 had no response or progressive disease. Eleven patients (6%) were not assessable for response because of early death. The probabilities of progression-free and overall survival at 5 years after transplantation were 31% (95% confidence interval [CI], 24% to 38%) and 37% (95% CI, 30% to 45%), respectively. In multivariate analysis, chemotherapy resistance, Karnofsky performance status score less than 80 at transplantation, age > or = 55 years at transplantation, receiving three or more prior chemotherapy regimens, and not receiving pre- or posttransplant involved-field irradiation therapy were adverse prognostic factors for overall survival. CONCLUSION: High-dose chemotherapy and autologous hematopoietic stem-cell transplantation should be considered for patients with diffuse aggressive NHL who never achieve a complete remission but who are still chemotherapy-sensitive and are otherwise transplant candidates.

Use of GnRH analogs for functional protection of the ovary and preservation of fertility during cancer treatment in adolescents: a preliminary report.

OBJECTIVE: Recent success in polychemotherapy (PCT) in adolescent female cancer patients has become a source of concern for specialists who also strive to preserve fertility. We studied whether gonadotropin-releasing hormone (GnRH) analogs could prevent the early onset of ovarian insufficiency postchemotherapy and protect fertility. METHODS: The patients were divided into three groups: Control group 1 (Group A), premenarchal patients aged 3 to 7.5 years (n = 5), were not given GnRH analogs administered prior to PCT. Postmenarchal patients (Group B), aged 14.7 to 20 years (n = 12) with normal menstrual rhythm and ovulatory cycles, received treatment with GnRH analogs prior to PCT. Control group 2 (Group C), postmenarchal patients aged 15.9 to 20 years (n = 4), received PCT but no GnRH analog protection. All groups received the PCT regimens CAVPE, CVPP, ABVD, TAMO, ARA-C, and MTT. In group B, leuprolide acetate inhibition was obtained with a depot injection administered each month before and during treatment with PCT. To accelerate the timing of ovarian regression, a subcutaneous injection (0.2 mg) was administered simultaneously. RESULTS: In Group A, patients had spontaneous menarche between the ages of 12 and 17.9 years, followed by normal menstruation and ovulatory cycles. Three patients became pregnant. After GnRH analog withdrawal, Group B patients continued with normal ovulatory cycles. Two patients became pregnant. Group C patients presented hypergonadotrophic hypoestrogenic amenorrhea. CONCLUSION: GnRH analog treatment before and during PCT enhances ovarian function and preserves adolescent fertility. The results must be confirmed in a larger study.

Autotransplants for Hodgkin's disease in first relapse or second remission: a report from the autologous blood and marrow transplant registry (ABMTR).

Although patients with relapsed Hodgkin's disease have a poor prognosis with conventional therapies, high-dose chemotherapy and autologous hematopoietic stem cell transplantation (autotransplantation) may provide long-term progression-free survival. We reviewed data from the Autologous Blood and Marrow Transplant Registry (ABMTR) to determine relapse, disease-free survival, overall survival, and prognostic factors in this group of patients. Detailed records from the ABMTR on 414 patients with Hodgkin's disease in first relapse (n = 295) or second complete remission (CR) (n = 119) receiving an autotransplant from 1989 to 1995 were reviewed. Median age was 29 (range, 7-64) years. Median time from diagnosis to relapse was 18 (range, 6-219) months; median time from relapse to transplant was 5 (range, <1-215) months. Most patients received high-dose chemotherapy without total body irradiation for conditioning (n = 370). The most frequently used high-dose regimen was cyclophosphamide, BCNU, VP-16 (CBV) (n = 240). The graft consisted of bone marrow (n = 246), blood stem cells (n = 112), or both (n = 56). Median follow-up was 46 (range, 5-96) months. One hundred-day mortality (95% confidence interval) was 7 (5-9)%. One hundred and sixty-five of 295 patients (56%) transplanted in relapse achieved CR after autotransplantation. Of these, 61 (37%) recurred. Twenty-four of 119 patients (20%) transplanted in CR recurred. The probability of disease-free survival at 3 years was 46 (40-52)% for transplants in first relapse and 64 (53-72)% for those in second remission (P < 0.001). Overall survival at 3 years was 58 (52-64)% after transplantation in first relapse and 75 (66-83)% after transplantation in second CR (P < 0.001). In multivariate analysis, Karnofsky performance score <90% at transplant, abnormal serum LDH at transplant, and chemotherapy resistance were adverse prognostic factors for outcome. Progression of Hodgkin's disease accounted for 69% of all deaths. Autotransplantation should be considered for patients with Hodgkin's disease in first relapse or second remission. Future investigations should focus on strategies designed to decrease relapse after autotransplantation, particularly in patients at high risk for relapse.

[Eight years of experience in a single institution in hematopoietic stem cell autologous transplantation in malignant hematological diseases and in solid tumors].

Between August 1991 and December 1998, 400 patients (lymphomas: 197; acute leukemia: 86; multiple myeloma: 70 and solid tumors: 47) were admitted for autologous transplantation. All patients were mobilized with chemotherapy plus G-CSF. The hematological recovery was similar in all disease groups. Patients with acute leukemias and multiple myeloma had a slower platelet recovery. Treatment-related death was 4.5%. The status of the disease at diagnosis was the most significant prognostic factor. With a median follow-up of 23 months the probability of event-free survival at 60 months was 46% for low grade lymphoma, 44% for intermediate and high grade lymphoma, 58% for Hodgkin's disease, 45% for acute myeloblastic leukemia, 38% for solid tumors and 15% for multiple myeloma. The probability of survival at 60 months was 67% for low grade lymphoma, 47% for intermediate and high grade lymphoma, 75% for Hodgkin's disease, 52% for acute myeloblastic leukemia, 54% for solid tumors and 25% for multiple myeloma. It can be concluded that autologous progenitor cell transplantation induces a complete and faster hematological recovery in all groups of patients without any late graft failure. Results are similar to those published in the literature. The treatment-related death was low and acceptable.

Autologous peripheral blood progenitor cell transplantation mobilized with high-dose cytarabine in acute myeloid leukemia in first complete remission.

BACKGROUND: The aim of this study was to increase disease-free survival (DFS) in AML in CR1 using a high-dose cytarabine consolidation plus G-CSF as in vivo purging and mobilization of CD34+ cells before ablative therapy and peripheral blood autograft. PATIENTS AND METHODS: Fifty-six consecutive AML patients (pts) (including 11 children < 15 years), with a median age of 32 years, were analyzed. After achievement of CR with cytarabine-mitoxantrone (7 + 3) in adults and a BFM-like protocol in children, pts were intensified with cytarabine 2 g/m2 x six doses plus mitoxantrone for adults, or, 3 g/m2 x six doses plus etoposide for children, followed by G-CSF 5 micrograms/kg SC daily. The ablative regimens used were busulfan and cyclophosphamide (Bu/Cy) in standard-risk pts plus etoposide (2400 mg/m2) for high-risk pts. RESULTS: For the 54 pts who underwent autologous transplant, the median time to reach > 1.0 x 10(9)/l neutrophils was 13 days (8-48), and to reach platelets > 25 x 10(9)/l 32 days (8-364), and the median numbers of red blood cell and platelet units transfused were 3 and 5, respectively. Six pts had treatment-related deaths (11%). The disease-free survival and overall survival at 30 months (mos) for the 56 eligible pts were 61% and 62%, respectively. Only two relapses were observed after 21 mos, while there were 12 relapses within 12 mos. CONCLUSIONS: The above treatment results in a similar DFS rate as does rescue with bone marrow cells, with faster neutrophil and platelet recovery.

IgG1-kappa biclonal gammopathy associated with multiple myeloma suggests a regulatory mechanism.

Multiclonal gammopathies associated with multiple myeloma may result either from a neoplastic transformation of a cell clone undergoing immunoglobulin class switching or from independent transforming events yielding proliferation of unrelated plasma cell clones. The simultaneous presence of more than one neoplastic clone may possess regulatory implications in terms of cell proliferation, clonal expansion, secretion of M-components or response to chemotherapy. We report a patient, diagnosed with multiple myeloma stage IIIa, who presented with two well-defined homogeneous IgG1-kappa components in the serum (designated WER-1 and WER-2) with striking differences in their plasma concentration and response to the classic melphalan/prednisone treatment. Immunochemical characterization and amino terminal sequence analysis of both the heavy and light chains of each M-component undoubtedly determined their biclonal origin. WER-1 was identified as IgG1(VHII)-kappaI while WER-2 was classified as IgG1(VHIII)-kappaIII. The plateau phase was characterized by very low or undetectable levels of WER-2, a high, almost constant, concentration of WER-1 and the absence of Bence Jones proteinuria, whereas these parameters were completely reversed during the escape phase with levels resembling those observed at the time of diagnosis. The statistically significant negative correlation between the biclonal components and the different susceptibility to the treatment clearly suggests regulatory interactions between the clones WER-1 and WER-2.

Meta-analysis of chemotherapy versus combined modality treatment trials in Hodgkin's disease. International Database on Hodgkin's Disease Overview Study Group.

DESIGN: To perform a meta-analysis of all randomized trials that compared chemotherapy (CT) alone versus combined modality treatment (CT + radiotherapy [RT]) for which individual patient data could be made available. PATIENTS AND METHODS: Data on 1,740 patients treated on 14 different trials that included 16 relevant comparisons have been analysed. Eight comparisons were designed to evaluate the benefit of additional RT after the same CT (CT1 v CT1 + RT; additional RT design). Eight comparisons were designed to evaluate whether RT in a combined modality setting can be substituted by CT using either more cycles of the same CT or regimens that contain additional drugs (CT1 + CT2 v CT1 + RT or CT1 v CT2 + RT; parallel RT/CT design). RESULTS: Additional RT showed an 11% overall improvement in tumor control rate after 10 years (P = .0001; 95% confidence interval [CI], 4% to 18%). No difference could be detected with respect to overall survival (P = .57; 95% CI, -10% to 4%). In contrast, when combined modality treatment was compared with CT alone in the parallel-design trials, no difference could be detected in tumor control rates (P = .43; 95% CI, -6% to 9%), but overall survival was significantly better after 10 years in the group that did not receive RT (P = .045; 8% difference; 95% CI, 1% to 15%). There were significantly fewer fatal events among patients in continuous complete remission (relative risk [RR], 1.73; 95% CI, 1.17 to 2.53; P = .005) if no RT was given. CONCLUSION: Combined modality treatment in patients with advanced-stage Hodgkin's disease overall has a significantly inferior long-term survival outcome than CT alone if CT is given over an appropriate number of cycles. The role of RT in this setting is limited to specific indications.

Randomized trial of CVPP for three versus six cycles in favorable-prognosis and CVPP versus AOPE plus radiotherapy in intermediate-prognosis untreated Hodgkin's disease.

PURPOSE: To evaluate in a randomized trial the impact of three versus six cycles of cyclophosphamide, vinblastine, procarbazine, and prednisone (CVPP) chemotherapy in favorable-prognosis and CVPP versus doxorubicin, vincristine, prednisone, and etoposide (AOPE) plus involved-field radiotherapy (RT) in intermediate-prognosis previously untreated Hodgkin's disease. PATIENTS AND METHODS: Of 256 patients evaluated, 80 with a favorable prognosis according to a prognostic index designed by the Grupo Argentina de Tratamiento de Leucemia Aguda (GATLA) were randomized to three versus six cycles of CVPP without RT and 176 with intermediate risk to CVPP versus AOPE, both for six cycles with RT between the third and fourth cycles of 30 Gy to the involved areas at diagnosis. CVPP consisted of intravenous (I.V.) cyclophosphamide and vinblastine on days 1 and 8, and oral procarbazine and prednisone on days 1 to 14, every 28 days. AOPE consisted of I.V. doxorubicin and vincristine on day 1, oral prednisone on days 1 to 5, and I.V. etoposide on days 1 and 3, every 28 days. RESULTS: Complete remission was obtained in 39 of 41 (95%) patients treated with three cycles of CVPP and 36 of 39 (92%) treated with six cycles in the favorable-risk group (difference not significant [NS]). In the intermediate-risk group, 89 of 92 (97%) treated with CVPP plus RT versus 75 of 84 (89%) treated with AOPE plus RT achieved a complete remission (P = .05). At 60 months, the event-free survival (EFS) and overall survival rates in the favorable-risk group were 80% and 91% for CVPP x 3 and 84% and 97% for CVPP x 6, respectively (P = NS). In the intermediate-risk group, 60-month EFS rate for CVPP plus RT was 85%, compared with 66% for AOPE plus RT (P = .009). The overall survival rate was 95% versus 87% respectively (P = .157). CONCLUSION: Three cycles of CVPP without RT are equally effective as six cycles in the favorable-risk group. However, in the intermediate-group, CVPP plus RT is superior to AOPE plus RT, with significantly fewer events before and after induction (P = .009), without a difference in overall survival.

Multivariate analyses of prognostic factors associated with hematopoietic recovery in autograft patients with different sources of progenitor cells. A GATMO experience. Argintine Group of Bone Marrow Transplant.

OBJECTIVE: To evaluate in a multivariate analysis the prognostic factors associated with hematopoietic recovery and the supportive care requirements after autotransplant of progenitor cells (PC) from various sources: bone marrow (BMPC), BMPC & peripheral blood (PBPC), and PBPC alone. PATIENTS AND METHODS: A total of 570 patients with hematological malignancies and solid tumors underwent high-dose therapy followed by autotransplant. PBPC were obtained after mobilization with chemotherapy and/or cytokines. One-hundred five patients received BMPC, 217 received BMPC & PBPC and 248 PBPC alone; all of the patients received G-CSF or GM-CSF after infusion. RESULTS: In a multivariate analysis the recovery of neutrophils was adversely associated with low numbers of nucleated cells infused (P < 0.13), bone marrow progenitor cell source, and diagnosis of multiple myeloma and acute leukemia (P < 0.001). The factors that adversely affected platelet recovery were low number of nucleated cells and diagnosis of multiple myeloma and acute leukemia (P < 0.001). CONCLUSIONS: We conclude that BMPC adversely affect neutrophil recovery while low numbers of nucleated cells and diagnosis of multiple myeloma and acute leukemia adversely affect both neutrophil and platelet recovery.

Bone marrow transplants from HLA-identical siblings in advanced Hodgkin's disease.

PURPOSE: To determine the outcome of HLA-identical sibling bone marrow transplants in advanced Hodgkin's disease. PATIENTS AND METHODS: We reviewed the data on 100 consecutive patients with Hodgkin's disease who received HLA-identical sibling bone marrow transplants between April 1, 1982 and August 12, 1992, reported to the International Bone Marrow Transplant Registry (IBMTR). The median interval from diagnosis to transplant was 2.5 years (range, < 1 to 14). All had advanced disease. Eighty-nine of 100 patients were not in remission at the time of transplant. Fifty had pretransplant Karnofsky scores less than 90% and 27 had active infection in the week before transplant. Patients received a variety of conditioning regimens; 45 received total-body radiation. RESULTS: The 100-day probability of acute graft-versus-host disease (GVHD) was 35% (95% confidence interval [CI], 26% to 46%); the 3-year probability of chronic GVHD was 45% (95% CI, 31% to 59%). The 3-year probability of relapse was 65% (95% CI, 50% to 78%). The 3-year probability of survival was 21% (95% CI, 14% to 30%). The 3-year disease-free survival rate was 15% (95% CI, 9% to 24%). CONCLUSION: HLA-identical sibling bone marrow transplants have a limited role in advanced Hodgkin's disease.

Long-term results of a multicentre randomised, comparative phase III trial of CHOP versus CNOP regimens in patients with intermediate- and high-grade non-Hodgkin's lymphomas. Novantrone International Study Group.

59 previously untreated patients with intermediate- or high-grade, stage II-IV non-Hodgkin's lymphoma (NHL) were entered into an open-label, randomised, multicentre study to compare the efficacy and safety of CHOP (cyclophosphamide, doxorubicin, vincristine and prednisolone) with that of CNOP (cyclophosphamide, mitoxantrone, vincristine and prednisolone). 10 patients refused treatment following randomisation. The remaining 349 patients received either the CHOP or CNOP regimen every 3 weeks for a maximum of six to eight cycles. The randomisation procedure was violated for 34 patients treated at two study centres. Data from these 34 patients were analysed separately for efficacy and survival. Data from the remaining 325 patients, 164 assigned to CHOP and 161 to CNOP, were used in the major efficacy and survival analyses. Of these 325 patients, 263 (81%) met the eligibility criteria of the protocol. Supplementary analyses of data from these 263 patients, 132 assigned to CHOP and 131 to CNOP, were conducted for efficacy and survival. Data from all 349 treated patients were analysed for safety. In the 325 randomised patients, the overall objective response rate was not significantly different between the two groups (chi 2 test, P = 0.35). The CHOP regimen had a 51% (83/164) complete remission (CR) rate compared with 40% (64/161) for the CNOP regimen (P = 0.05). Among those with CR, the median time to response was 104 days with the CHOP regimen and 77 days with the CNOP regimen, and the median duration of CR was 667 and 1833 days, respectively. The median time to progression was 449 days for CHOP patients and 564 days for CNOP patients. The median survival time was 932 days for CHOP patients and 1801 days for CNOP patients, with a risk of death on CNOP relative to CHOP of 0.93% (95% confidence interval 0.68-1.27). After 5 years, 50% of patients in the CNOP arm and 40% of patients in the CHOP arm were still alive; these differences between treatment groups were not statistically significant. The median time to treatment failure (TTF) was 285 days for patients on the CHOP arm and 282 days for patients on the CNOP arm. Separate analyses of 263 eligible randomised patients, and 34 patients in whom the randomisation procedure was not followed, yielded similar results for remission rate, TTF, duration of CR and estimated overall survival. The incidence of non-haematological events, such as severe nausea and vomiting (P < 0.01), mucositis (P < 0.05) and alopecia (P < 0.001), were significantly lower in were significantly lower in patients treated with CNOP as compared with those who received the CHOP regimen. The incidence of cardiovascular toxicity of any severity was similar in the two groups. While severe and potentially life-threatening neutropenia occurred more frequently in patients treated with CNOP compared with CHOP (0.05 > P > 0.10), the incidence of infection of any severity was similar in both arms. We conclude that CHOP and CNOP regimens were both efficacious in patients with previously untreated aggressive NHL.

A randomized study of mitoxantrone plus cytarabine versus daunomycin plus cytarabine in the treatment of previously untreated adult patients with acute nonlymphocytic leukemia.

Between May 1985 and November 1988, 143 adult patients with previously untreated acute nonlymphocytic leukemia were randomized to receive mitoxantrone and cytarabine (MTT+Ara-C) or daunomycin and cytarabine (DNM+Ara-C) in order to compare the efficacy and acute and chronic toxicities. Therapy consisted of 3 days of MTT 12 mg/m2/i.v. or DNM 45 mg/m2/i.v.; both groups received Ara-C 100 mg/m2 daily by continuous infusion (CI) for 7 days. Those who failed to achieve a complete remission after one induction course received a second induction course for 2 and 5 days at the same doses. All the patients who achieved complete remission received two consolidations of 2 days of MTT or DNM and 5 days of Ara-C in CI at the same dose as for induction. Of the 72 patients on MTT+Ara-C, 38 (53%) achieved complete remission, compared with 29 (43%) of 67 treated with DNM+Ara-C. Three and 5 patients had partial remission, 7 and 18 failed to respond, 24 and 15 died in the first 21 days of induction, of those treated with MTT+Ara-C or DNM+Ara-C, respectively (p = 0.34). Median duration of complete remission and survival was 185 and 103 days or 165 and 160 days, respectively (p = 0.85). More early deaths were observed with MTT+Ara-C due to greater myelosuppression, and a higher incidence of failure with DNM+Ara-C. No significant differences between treatment groups were observed in 21 categories of adverse events. The results demonstrate similar incidence of complete response, length of duration of complete remission, overall survival, and toxicity with MTT+Ara-C and DNM+Ara-C.

[Comparative study of 1st generation versus 2d generation (CAVPE) combinations in intermediate and high-grade lymphomas].

PURPOSE: To compare four first generation chemotherapy regimes (FGR) used by GATLA in low and intermediate grade lymphomas. Versus a second generation regimen called CAVPE. PATIENTS AND METHODS: A group of 205 patients treated with FGR (79 with BACOP, 89 with COPP, 19 with CHOP, and 18 with CNOP), and 244 others treated with the combination of cyclophosphamide, doxorubicin, vincristine, prednisone and etoposide (CAVPE) were included. Two randomized phase III multicentric studies, COPP vs BACOPP and CHOP vs CNOP, as a whole group, were compared with the second generation scheme, CAVPE. All the patients with FGR received 6 monthly treatment courses, and the CAVPE patients were given 8 monthly courses. RESULTS: The median age was 55 years (18-85) for the FGR group and 51 years (15-79) for the CAVPE group. The stage distribution for both FGR and CAVPE groups was, respectively, as follows: II: 38 and 55 cases; III 80 and 84 cases; IV: 87 and 105 cases. No significant differences were found between both groups when comparing other characteristics of the patients, namely, sex, symptoms, mediastinal, abdominal or extranodal involvement, liver, spleen or bone-marrow infiltration, and bulky tumoural mass. The percentage of complete remission (CR) was 52% (107/205) in the patients treated with FGR, and 67% (163/244) in the CAVPE group (p < 0.001). The estimated probability of sustained first CR at 72 months was 38% for the FGR group and 54% for the CAVPE group (p = 0.0167), whereas 17% and 36%, respectively, of the evaluable patients were alive and well, with no signs of disease progression (p = 0.000). The 72-month survival was estimated in 32% and 51%, respectively, for each group (p = 0.0004). CONCLUSIONS: 1. CAVPE seems to offer better responses and disease-free survival in this non-selected group of low and intermediate lymphoma patients. 2. The better results in terms of CR and lower incidence of relapses attained with CAVPE with regard to FGR are probably related with a number of facts, such as the use of more aggressive drugs, higher doses, a better drug combination rationale, the inclusion of new drugs, such as etoposide, or a selection of the patients.
