Scaling of movement velocity: a measure of neuromotor retardation in individuals with psychopathology

The combination of ifosfamide, carboplatin and etoposide (modified ICE), was evaluated for its toxicity and activity in relapsed or refractory aggressive non-Hodgkin's lymphoma. Twenty patients, 14-69 years of age, with relapsed (19 cases) or refractory (one case) aggressive non-Hodgkin's lymphoma were treated with modified ICE therapy, consisting of ifosfamide 6 g/m2 (1.2 g/m2 day 1-5), carboplatin 400 mg/m2 (day 1) and etoposide 500 mg/m2 (100 mg/m2 day 1-5). The regimen was repeated at approximately 28-day intervals. All patients had undergone a doxorubicin-containing regimen before modified ICE therapy. Median total dose of previously received doxorubicin was 406 mg/m2 (range: 200-825 mg/m2). The median interval from diagnosis to modified ICE therapy was 9.4 months (range: 3.6-121 months). Two patients achieved CR and five achieved PR out of 16 patients with measurable lesions (response rate 43.8%; 95% confidence interval 19.0-68.6%). Median overall survival was 227 days (range: 41-552 days) from the start of modified ICE therapy. Myelosuppression was the most serious toxicity, namely 16 patients (80%) and 11 patients (55%) showed grade 4 neutropenia and grade 4 thrombocytopenia after the first course, respectively. Modified ICE therapy might be an active regimen with acceptable toxicity as a salvage chemotherapy in aggressive non-Hodgkin's lymphoma.     

SLP-76-Cbl-Grb2-Shc interactions in FcgammaRI signaling

PURPOSE: To improve response and survival rates in patients with high-risk rhabdomyosarcoma (RMS), extraosseous Ewing's sarcoma, and undifferentiated sarcoma, we used a short course of induction with multi-agent chemotherapy, hyperfractionated radiotherapy, and surgery when possible. Consolidation was with intensive chemotherapy and autologous bone marrow transplantation (ABMT). PATIENTS AND METHODS: Twenty-six patients (21 with RMS, three with undifferentiated sarcoma, and two with extraosseous Ewing's sarcoma) were entered onto the protocol between June 1990 and March 1994. Induction consisted of ifosfamide, etoposide, doxorubicin, dactinomycin, cyclophosphomide, and vincristine, and a split course of hyperfractionated radiotherapy. Patients who attained a complete response (CR) or good partial response (GPR) received consolidation with high-dose melphalan and etoposide followed by ABMT. RESULTS: Of 26 previously untreated patients 19 (73%) achieved a CR (n=13) or GPR (n=6) at the completion of induction and underwent ABMT. Two-year overall survival (OS) was 56% (95% confidence interval [CI], 36% to 76%) and progression-free survival (PFS) was 53% for the whole group (95% CI, 33% to 73%). CONCLUSION: Consolidation of response by myeloablative chemotherapy was well tolerated. Split-course hyperfractionated radiotherapy did not increase the rate of local control. The results of this short-course therapy were comparable to previous therapies of 1 to 2 years' duration. Induction and consolidation chemotherapy, as well as radiation dose, could be further intensified, since no death due to toxicity occurred among these patients.     

Peripheral blood progenitor cell mobilization with Dexa-Beam/G-CSF, ether lipid purging, and autologous transplantation after high-dose CBV treatment: a safe and effective regimen in patients with poor risk malignant lymphomas

High-dose chemotherapy followed by autologous peripheral blood progenitor cell transplantation (PBPCT) is increasingly applied in patients with relapsed, poor risk malignant lymphomas. Different strategies for progenitor cell mobilization using cytoreductive chemotherapy, hematopoietic growth factors, or both have been described. We studied the safety and efficacy of a modified DexaBEAM regimen (dexamethasone, BCNU [carmustine], etoposide, ara-C, melphalan) followed by granulocyte-colony stimulating factor (G-CSF) that was administered in order to minimize any residual disease and to obtain a sufficient amount of progenitor cells in the autografts. Until now, 16 patients at poor risk (8 with Hodgkin's disease, 8 with non-Hodgkin's lymphoma) entered the study. All the 12 patients with measurable disease at study entry responded to DexaBEAM. Median time of subsequent leukopenia (leukocytes < 1.000/microL) was 6 days (range 5-8 days). Peak numbers of CD34+ hematopoietic progenitor cells appeared in the peripheral blood after a median of 20 days (range 18-22 days) after onset of therapy. At that time, peripheral mononuclear cells were collected for autografting. Thereafter, the leukapheresis products were frozen until the day of transplantation, either unpurged in the case of Hodgkin's disease or purged with the ether lipid edelfosine in cases of non-Hodgkin's lymphoma. After high-dose chemotherapy with the CBV regimen (cyclophosphamide, BCNU, etoposide) the patients received their autografts, followed again by G-CSF treatment. A stable hematopoietic recovery was reached with granulocytes > 2.000/muL within 11 days (range 8-17 days), and platelets > 50.000/microL within 15 days (range 10-31 days), respectively, without significant differences between the purged and unpurged transplants. After a median follow-up of 28 months (range 1-40 months) 7 patients are alive without signs of recurrent disease, while 1 patient has died due to acute treatment related toxicity. Three patients had refractory disease, and 5 have relapsed of whom 4 have died. In summary, the DexaBEAM/G-CSF/CBV strategy appears to be safe and effective for salvage treatment in patients with poor risk malignant lymphomas.     

A phase II multicenter trial of high-dose sequential chemotherapy and peripheral blood stem cell transplantation as initial therapy for patients with high-risk non-Hodgkin's lymphoma

The purpose of this study was to evaluate the safety and feasibility of front-line high-dose sequential (HDS) chemotherapy with peripheral blood stem cell (PBSC) transplantation in patients with newly diagnosed high-risk non-Hodgkin's lymphoma (NHL). Thirty-two patients with high-risk NHL (defined by the age-adjusted international index) underwent HDS chemotherapy followed by PBSC transplantation and consolidative radiotherapy. Twenty-eight patients (88%) had intermediate/high grade NHL and four patients (12%) had small noncleaved or lymphoblastic lymphoma. Twenty-four patients were classified as high-intermediate-risk (two risk factors) and eight patients were classified as high-risk (three risk factors). The five phases of HDS (see Fig. 1) consisted of Phase I (adriamycin, vincristine, and prednisone); Phase II (cyclophosphamide, filgrastim [G-CSF], and PBSC harvest); Phase III (methotrexate, leucovorin, vincristine; Phase IV (etoposide, filgrastim [G-CSF]); and Phase V (mitoxantrone, melphalan, autologous peripheral blood stem cell infusion, and filgrastim [G-CSF]). Radiation therapy was given to sites of previous bulk disease, 2400 cGy, (D + 30-100)]. Toxicity, engraftment, hospital utilization, overall survival, and relapse-free survival were evaluated. The high-dose sequential chemotherapeutic regimen was well tolerated. Treatment-related mortality was 6.25% with two deaths occurring secondary to sepsis and one death was caused by progressive disease. The major toxicity in Phase I-IV was grade 3 nausea/vomiting. The major toxicity in Phase V was grade 3 or 4 nausea/vomiting and mucositis. The median follow-up is 18.8 months (range 4-44 months). The overall survival (OS) and relapse-free survival (RFS) at 18 months for all patients were 78% (95% CI 37-90%) and 67% (95% CI 46-88%), respectively. The OS at 18 months for all patients, excluding the four patients with either small noncleaved or lymphoblastic lymphoma, was 82% (95% CI 65-98%) vs. 30% (95% CI 0-86%) (p = 0.0059). One patient in this latter group remains alive at 6 months follow-up. The RFS for all patients, excluding the four patients with either small noncleaved or lymphoblastic lymphoma, was 78% (95% CI 58-97%) vs. 0% (95% CI 0-0%) (p = 0.0004). High-dose sequential chemotherapy with initial PBSC transplantation is well tolerated and appears effective in high-risk NHL. Superior results were noted in patients with intermediate grade versus those with small noncleaved or lymphoblastic NHL.     

Thought control strategies in acute stress disorder

Relapse after transplant for malignant lymphomas remains the main cause of treatment failure. Most conditioning regimens contain total body irradiation (TBI). We investigated the toxicity and efficacy of an intensified chemotherapy conditioning regimen without TBI in patients with relapsed or high-risk malignant lymphoma who had received prior radiation therapy and were therefore not eligible for TBI. Twenty patients with a median age of 38 (18-56) and relapsed or high-risk malignant non-Hodgkin's lymphoma (NHL, n = 16) or Hodgkin's disease (HD, n = 4) underwent high-dose chemotherapy consisting of busulfan (16 mg/kg), cyclophosphamide (120 mg/kg) and etoposide 30 mg/kg (n = 8) or 45 mg/kg (n = 12) followed by peripheral stem cell support (n = 14), autologous bone marrow (n = 3), allogeneic (n = 2) or syngeneic (n = 1) transplantation. All but two had chemosensitive disease before high-dose chemotherapy. The main toxicity -- according to the Bearman score -- was mucositis II in 18 (90%) patients; five patients (25%) suffered a grade I hepatic toxicity. GI toxicity I occurred in three (15%) and renal toxicity I in two patients (10%). Sixty percent of the patients developed transient dermatitis with erythema and three of them (15%) had skin desquamation; one patient experienced asymptomatic pancreatitis. Toxicity was slightly higher in patients treated with 45 mg/kg etoposide. One patient (5%) died of treatment-related venoocclusive disease. After a median follow-up of 50 months (24-84) the disease-free and overall survival were 50% and 55%. One of the nine relapsing patients developed secondary AML 18 months after transplant. High-dose busulfan, cyclophosphamide and etoposide is an effective regimen resulting in long-term disease-free survival in 50% of patients with relapsed malignant lymphoma and prior radiation therapy. The toxicity is moderate with a low treatment-related mortality (5%).     

VACOP-B versus VACOP-B plus autologous bone marrow transplantation for advanced diffuse non-Hodgkin's lymphoma: results of a prospective randomized trial by the non-Hodgkin's Lymphoma Cooperative Study Group

PURPOSE: The aim of this multicenter randomized study was to compare conventional therapy with conventional plus high-dose therapy (HDT) and autologous bone marrow transplantation (ABMT) as front-line treatment for poor-prognosis non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS: Between October 1991 and June 1995, 124 patients, aged 15 to 60 years, with diffuse intermediate- to high-grade NHL (Working Formulation criteria), stages II bulky (> or = 10 cm), III, or IV were enrolled. Sixty-one patients were randomized to receive etoposide, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin (VACOP-B) for 12 weeks and cisplatin, cytarabine, and dexamethasone (DHAP) as a salvage regimen (arm A), and 63 to receive VACOP-B for 12 weeks plus HDT and ABMT (Arm B). RESULTS: There was no significant difference in terms of complete remissions (CRS) in the two groups: 75% in arm A, and 73% in arm B. The median follow-up observation time was 42 months. The 6-year survival probability was 65% in both arms. There was no difference in disease-free survival (DFS) or progression-free survival (PFS) between the two groups. DFS was 60% and 80% (P = .1) and PFS was 48% and 60% (P = .4) for arms A and B, respectively. Procedure feasibility was the major problem. In arm B, 29% of enrolled patients did not undergo HDT and ABMT. A statistical improvement in terms of DFS (P = .008) and a favorable trend in terms of PFS (P = .08) for intermediate-/high- plus high-risk group patients assigned to HDT and ABMT was observed. CONCLUSION: In this study, conventional chemotherapy followed by HDT and ABMT as front-line therapy seems no more successful than conventional treatment in terms of overall results. However, our results suggest that controlled studies of HDT plus ABMT should be proposed for higher risk patients.     

A case of chronic B cell lymphocytic leukemia with expression of CD8 antigen on leukemic cells

PURPOSE: To determine the toxicity and prognosis of patients with relapsed and refractory diffuse aggressive non-Hodgkin's lymphoma (NHL) who underwent an autologous bone marrow transplant (ABMT) using augmented preparative regimens, treated in a major cooperative group setting, and to examine prognostic factors for outcome. PATIENTS AND METHODS: Ninety-four patients with either chemosensitive (50 patients) or chemoresistant (44 patients) relapse, including 22 who failed induction chemotherapy, were treated with high-dose cyclophosphamide and etoposide with total-body irradiation (TBI) (67 patients) or an augmented carmustine (BCNU), cyclophosphamide, and etoposide (BCV) preparative regimen (27 patients) and an ABMT at 16 Southwest Oncology Group (SWOG) transplant centers. All relapsing patients were required to undergo a minimum of two courses of salvage therapy to determine chemosensitivity before transplant. Overall (OS) and progression-free survival (PFS) were determined and a Cox regression model was used to assess potential prognostic variables. RESULTS: Of the 94 eligible patients, there were 10 (10.6%) deaths before day 50 posttransplant because of infection (six deaths), hemorrhagic alveolitis (three deaths), or bleeding (one death). The median 3-year PFS and OS for the entire group was 33% and 44%. For those with chemosensitive disease the PFS and OS were 42% and 55%, whereas for those with chemoresistant disease the PFS and OS were 22% and 29%. The PFS and OS for those failing induction chemotherapy were 27% and 32%. The relapse rates within the first 3 years for the chemosensitive relapse, chemoresistant, and induction failure groups were 61%, 40%, and 59%, respectively. For both PFS and OS, only disease status at transplant was a significant factor in the multivariate Cox model. CONCLUSION: These results single institutional pilot trials exploring augmented preparative regimens. Patients undergoing transplantation for resistant disease, particularly those failing induction chemotherapy, appear to have an improved prognosis as compared with reports using standard preparative regimens. Therapies other than manipulation of standard preparative regimens appear to be required to decrease relapses following autotransplantation.     

High-dose chemotherapy with carboplatin, etoposide and ifosfamide followed by autologous stem cell rescue in patients with relapsed or refractory malignant lymphomas: a phase I/II study

Patients with relapsed or refractory non-Hodgkin's lymphomas (NHL) and Hodgkin's disease (HD) with recurrences after an anthracyclin-containing regimen only have a chance of cure of below 10% with conventional chemotherapy. In order to improve their prognosis, we started a phase I/II trial using high-dose therapy comprising carboplatin, together with etoposide and ifosfamide (CEI), followed by autologous stem cell rescue (ASCR) as consolidation after salvage treatment. Since September 1990, 40 patients with intensively pretreated advanced NHL (n = 24) or HD (n = 16) received one cycle of high-dose therapy (HDT) consisting of carboplatin 1500 mg/m2, ifosfamide 10 g/m2 and etoposide in escalating doses from 1200 mg/m2 to 2400 mg/m2 followed by ASCR. Thirty-nine patients were assessable for toxicity and response. The following doses appeared to be safe: carboplatin 1500 mg/m2, etoposide 2400 mg/m2 and ifosfamide 10 g/m2. All patients developed grade 3 nausea and grade 3 or 4 mucositis. Granulocytopenic fever occurred in 100% with grade 4 infections in 15%. Mild transient kidney toxicity was noted in 36% and liver toxicity in 20% of patients. One toxic death occurred (2.5%). Objective responses were obtained in 36 of 39 patients (92%) with complete remissions (CR) in 24 patients (61.5%) and partial remissions (PR) in 12 (30.7%). Median observation time for surviving patients was 23.3 months (range 3.4-52.3). The probabilities of overall, event-free and relapse-free survival at 2 years are 62, 39 and 55%, respectively. Patients with primary refractory disease or resistant relapse had a poor prognosis. High-dose carboplatin, etoposide and ifosfamide plus autologous stem cell rescue represents an effective, potentially curative salvage treatment with acceptable toxicities.     

In vivo purging with high-dose cytarabine followed by high-dose chemoradiotherapy and reinfusion of unpurged bone marrow for adult acute myelogenous leukemia in first complete remission

PURPOSE: To evaluate in a prospective study the efficacy of autologous bone marrow transplantation (BMT) in adult patients with acute myelogenous leukemia (AML) in first remission, using a single course of high-dose Cytarabine (HD Ara-C) consolidation therapy as in vivo purging. PATIENTS AND METHODS: Sixty consecutive adult patients with AML in first complete remission (CR) were treated with HD Ara-C consolidation therapy as a method of in vivo purging before marrow collection. High-dose therapy consisted of fractionated total-body irradiation (FTBI) 12 Gy, intravenous etoposide 60 mg/kg, and cyclophosphamide 75 mg/kg, followed by reinfusion of cryopreserved marrow. RESULTS: Sixty patients underwent consolidation treatment with HD Ara-C with the intent to treat with autologous BMT. Sixteen patients were unable to proceed to autologous BMT (10 patients relapsed, one died of sepsis, one developed cerebellar toxicity, two had inadequate blood counts, and two refused). Forty-four patients underwent autologous BMT and have a median follow-up time of 37 months (range, 14.7 to 68.7) for patients who are alive with no relapse. The cumulative probability of disease-free survival (DFS) at 24 months in the intent-to-treat group is 49% (95% confidence interval [CI], 37% to 62%) and in those who actually underwent autologous BMT is 61% (95% CI, 46% to 74%). The probability of relapse was 44% (95% CI, 31% to 58%) and 33% (95% CI, 20% to 49%) for the intent-to-treat and autologous BMT patients, respectively. CONCLUSION: This approach offers a relatively high DFS rate to adult patients with AML in first CR. The results of this study are similar to those achieved with allogeneic BMT.     

Epirubicin (CEOP-Bleo) versus idaurubicin (CIOP-Bleo) in the treatment of elderly patients with aggressive non-Hodgkin's lymphoma: dose escalation studies

One hundred and sixty nine untreated elderly patients (median age 69 years old; range 60-89 years old) with high or high-intermediate clinical risk non-Hodgkin's lymphoma were enrolled in a controlled clinical trial to evaluate escalated doses of epirubicin in a CEOP-Bleo regimen (cyclophosphamide, vincristine, epirubicin, prednisone and bleomycin), compared to escalated doses of idaurubicin in an CIOP-Bleo regimen (idaurubicin instead of epirubicin). Overall, 71% of the patients in the CEOP-Bleo arm achieved a complete response compared to only 48% in the CIOP-Bleo regimen (p < 0.01). At actuarial 3 year, 72% of the patients treated with the CEOP-Bleo regimen remained alive and free of disease, compared to 34% in the CIOP-Bleo arm (p < 0.01). Dose intensity was 0.86 in the epirubicin regimen, similar to 0.82 in the idaurubicin arm. Toxicities were more frequent and severe in the CEOP-Bleo regimen; however, no death-related treatment was observed in either groups. Cardiac toxicity was also similar in both arms. We conclude that treatment of elderly paitents with aggressive non-Hodgkin's lymphoma should be considered a curative attempt and not only palliative. The use of full doses of chemotherapy should be contemplated in elderly patients. Epirubicin, in escalating doses, is a drug with mild toxicity and improvement in outcome in this setting is observed. We cannot confirm the usefulness of idaurubicin, including escalating doses, in the treatment of patients with aggressive malignant lymphoma, because the complete response rate and survival were worse than other chemotherapy regimens. We feel that the CEOP-Bleo regimen with escalated doses of epirubicin is a useful option in the treatment of elderly patients with aggressive non-Hodgkin's lymphoma.     

Myelodysplastic syndrome as a late complication following autologous bone marrow transplantation for non-Hodgkin's lymphoma

PURPOSE: To determine the incidence, natural history, and risk factors associated with myelodysplastic syndrome (MDS) occurring as a late complication following autologous bone marrow transplantation for patients with non-Hodgkin's lymphoma. METHODS: We retrospectively reviewed the charts of all 262 patients who underwent autologous bone marrow transplantation for non-Hodgkin's lymphoma at the Dana-Farber Cancer Institute from 1982 through 1991. Although patients received a variety of treatments before they were eligible for transplant, identical myeloablative therapy (cyclophosphamide 60 mg/kg/d for 2 days plus total-body irradiation twice daily for 3 days) was administered in each case. By collecting data on pretransplant and early posttransplant variables, we attempted to identify risk factors for the development of MDS. RESULTS: The crude overall incidence of posttransplant MDS or acute myeloid leukemia (AML) was 7.6%. The actuarial risk at 6 years was 18% +/- 9%. The median time of onset was 31 months (range, 10 to 101) after transplant or 69 months (range, 27 to 141) after initial treatment for lymphoma. Pretreatment variables predictive for the development of MDS (univariate analysis) included prolonged interval between initial treatment and the transplant procedure (P = .003), increased duration of exposure to chemotherapy (P = .019) or to alkylating agents (P = .045), and use of radiation therapy (P = .032) or pelvic radiation (P = .003) before transplant. CONCLUSION: MDS is a potential complication of autologous bone marrow transplantation for non-Hodgkin's lymphoma; bone marrow stem-cell damage sustained before the transplant may be the most important risk factor.     

Observations on template switching during DNA replication through long inverted repeats

High dose chemotherapy with autologous stem cell transplantation (ASCT) is increasingly used in the treatment of patients with lymphoma. As previously shown with conventional treatments, second neoplasms are emerging as a long term complication of the procedure. In this study, we investigate the incidence of second neoplasm in a cohort of 171 patients treated with BEAM or BEAC regimens for Hodgkin's disease (n = 62) and non-Hodgkin's lymphomas (n = 109) followed up for a median of 52 months post ASCT. Six patients developed six second malignancies 12 to 105 months after ASCT: fibrolamellar carcinoma of the liver, malignant fibrous histiocytoma, pancreatic carcinoma, squamous cell carcinoma of the lung, invasive carcinoma of the vulva and acute myelogenous leukemia. The cumulative actuarial risk for developing second malignancy is 16.7% (95% confidence interval: 5.9-39.3%) 13 years after transplant. The age-adjusted incidence of cancer in the study group is 4.1 times higher than that of primary cancer in the general population. These data confirm that ASCT recipients are at increased risk of later malignancies. This complication adds significant morbidity and mortality to the transplant process and therefore, needs to be taken into account in long term evaluation of new strategies which involve early intensification in the treatment of lymphomas.     

Dexa-BEAM in patients with Hodgkin's disease refractory to multidrug chemotherapy regimens: a trial of the German Hodgkin's Disease Study Group

PURPOSE: A prospective phase II study was conducted to evaluate the efficacy of dexamethasone, carmustine, etoposide, cytarabine, and melphalan (Dexa-BEAM) as salvage chemotherapy for patients with Hodgkin's disease. PATIENTS AND METHODS: Fifty-five patients progressing on or relapsing after eight- or 10-drug chemotherapy (cyclophosphamide, vincristine, procarbazine, and prednisone plus doxorubicin, bleomycin, vinblastine, and dacarbazine [COPP+ABVD] or COPP+ABV+ifosfamide, methotrexate, etoposide, and prednisone [IMEP]) were treated with Dexa-BEAM. Patients who responded after two cycles of Dexa-BEAM either continued treatment for another two to three cycles or received high-dose chemotherapy/autologous bone marrow transplantation (HDCT/ABMT) with cyclophosphamide, etoposide, and carmustine (BCNU) (CVB) as conditioning regimen. RESULTS: Seventeen patients (31%) achieved a complete remission and 16 (29%) a partial remission, resulting in a response rate of 60% (95% confidence interval, 46% to 73%). Progressive disease developed in 18 patients. Toxicity of Dexa-BEAM was acceptable with pronounced, but temporary World Health Organization (WHO) grade III/IV granulocytopenia and thrombocytopenia occurring in more than 90% of all courses. Two patients died of sepsis during granulocytopenia. Three prognostic subgroups could be distinguished: (1) patients progressing on initial chemotherapy, (2) patients relapsing within 12 months, and (3) patients with late relapses. The response rates for these groups were 52%, 60%, and 83%, and the median survival duration 12, 29, and 40+ months, respectively. In a nonrandomized comparison, the survival of patients who responded to two cycles of Dexa-BEAM and had additional cycles of Dexa-BEAM (n = 14) was not different from those responding patients who underwent HDCT/ABMT (n = 19). However, the power to detect a 20% survival difference was only 33% in this comparison. CONCLUSION: Dexa-BEAM is an effective salvage treatment for patients with Hodgkin's disease who fail to respond to multidrug chemotherapy. Efficacy and toxicity are comparable to HDCT/ABMT and underline the need for prospective randomized trials to define better the role of HDCT with and without ABMT in these patients.     

Treatment of localized non-Hodgkin's lymphomas of the head and neck

BACKGROUND: Localized non-Hodgkin's lymphomas of the head and neck are generally treated with radiotherapy with or without chemotherapy, although the results of treatment of localized non-Hodgkin's lymphomas with of treatment of localized non-Hodgkin's lymphomas with chemotherapy alone appear to be favorable. It is unclear if and when combined modality therapy should be used. METHODS: The authors reviewed the records of 53 patients with Stage I or II non-Hodgkin's lymphoma of the head and neck, who were treated with radiotherapy alone (13 patients), chemotherapy according to the cyclophosphamide, doxorubicin, vincristine, prednisone- (CHOP) regimen (27 patients), or a combination of both treatments (13 patients). RESULTS: A complete remission was achieved in 43 (81%) patients. The 5-year survival for all patients was 78%. A significant difference (P = 0.03) in 5-year relapse-free survival was observed between Stages I and II disease, of 92 and 60%, respectively. Extensive tumor was a significantly poor prognostic factor (P = 0.04) with a 5-year relapse-free survival of 52 versus 84% for patients with nonextensive lymphoma. Eight relapses occurred; in five patients, a local relapse was the first presentation. Although salvage radiotherapy was successful in these five patients, a distant relapse developed in three. No relapses were observed in previously irradiated areas. CONCLUSIONS: Our results suggest that radiotherapy alone is the appropriate treatment for nonextensive Stage I intermediate grade non-Hodgkin's lymphoma of the head and neck. For extensive Stage I or II non-Hodgkin's lymphomas, chemotherapy is preferable. The value of combined modality therapy remains unclear.     

Treatment of intermediate risk rhabdomyosarcoma and undifferentiated sarcoma with alternating cycles of vincristine/doxorubicin/cyclophosphamide and etoposide/ifosfamide

Over 50% of patients with newly diagnosed rhabdomyosarcoma (RMS) are in the 'intermediate risk' group with a 3-year progression-free survival of approximately 65%. This group consists of stage 1, group III, non-orbit tumours; stage 2, group II and III; and all stage 3 patients utilising the Intergroup Rhabdomyosarcoma Study (IRS) staging system. The role of doxorubicin in the treatment of RMS has been controversial. Ifosfamide, both alone and in combination with etoposide, has significant activity in patients with RMS. The aim of this pilot study was to examine the efficacy and toxicity of a chemotherapy regimen of alternating cycles of vincristine/doxorubicin/cyclophosphamide and etoposide/ifosfamide for intermediate risk RMS. 30 patients with intermediate risk RMS or undifferentiated sarcoma (US) were treated with alternating cycles of vincristine/doxorubicin/cyclophosphamide (VDC) and etoposide/ifosfamide (EI) at planned intervals of 3 weeks. Local treatment of the tumour in most cases was performed after four cycles of chemotherapy, followed by an additional 10 cycles of chemotherapy. At a median follow-up of 37.5 months, the Kaplan-Meier estimate of 3-year event-free survival was 85% (95% confidence interval 72-99%). The overall survival at 3 years was 91% (95% confidence interval 80-100%). No patient died from toxicity. The most common toxicity was febrile neutropenia in 35% of VDC and 26% of EI cycles. No nephrotoxicity or cardiac toxicity was seen. No patient progressed prior to week 12 local therapy. Alternating cycles of VDC and EI are an effective treatment for patients with intermediate risk RMS and US. Toxicity is tolerable. Delaying local treatment until week 12 does not compromise outcome.     

Premature ejaculation and serotonergic antidepressants-induced delayed ejaculation: the involvement of the serotonergic system

OBJECTIVE: To analyze the causes of therapeutic success and failure in the management of patients with high-risk gestational trophoblastic tumors (GTTs). STUDY DESIGN: Analysis of 272 consecutive high-risk patients treated at the trophoblastic disease center at the Charing Cross Hospital between 1979 and 1995. RESULTS: EMA (etoposide, methotrexate, actinomycin D)/CO (cyclophosphamide, vincristine) chemotherapy is our treatment of choice for patients with high-risk GTT. In 272 consecutive patients the cumulative five-year survival was 86.2% (95% confidence interval, 81.9-90.5%). No deaths occurred from GTT more than two years after the start of treatment. In patients whose disease became resistant to EMA/CO or relapsed after receiving EMA/CO, the majority (70%) could be salvaged with further chemotherapy (usually with the EP (etoposide, cisplatin)/EMA chemotherapy with or without surgery. Multivariate analysis identified the following adverse prognostic factors: presence of liver metastases (P < .0001), prolonged interval from antecedent pregnancy (P < .0001), presence of brain metastases (P = .0008) and term delivery of antecedent pregnancy (P = .045). Intensive chemotherapy for treating high-risk GTT carries a small risk of inducing second malignancies, and two patients developed acute myeloid leukemia, 2 cervical malignancy and 1 gastric adenocarcinoma after receiving EMA/CO chemotherapy. CONCLUSION: EMA/CO is an effective and well-tolerated regimen for high-risk GTT. Salvage chemotherapy with EP/EMA is effective in the majority of patients whose disease is resistant to EMA/CO and should be combined with surgery when the dominant site of resistant disease is known. Major adverse prognostic variables have been identified, and patients with combinations of these factors should be considered for innovative therapeutic approaches from the outset.     

Autologous stem cell transplantation (ASCT) for poor prognostic Hodgkin's disease (HD): comparative results with two CBV regimens and importance of disease status at transplant

Clinical outcome of 47 consecutive patients with advanced HD who underwent ASCT in our Department was analyzed retrospectively. Median age was 28 years (28 males and 19 females). At transplant, 15 (32%) patients were in CR (five in first CR after two chemotherapy regimens and 10 in second CR), eight (17%) in PR (seven without a prior CR), 22 (51%) had relapsing disease (19 with sensitive relapse) and two had primary refractory disease. The CVB regimen with two different schedules was used: 22 (47%) patients received standard CBV (CY 6 g/m2, BCNU 300 mg/m2 and etoposide 600 mg/m2) and 25 (53%) received an increased CBV dose (CY 7.2 g/m2, BCNU 440 mg/m2 and etoposide 2 g/m2). Antitumor response for 28 evaluable patients was similar for both CBV regimens: 87 and 75% (P=0.39). At 7.2 years, actuarial overall survival (OS), progression-free survival (PFS) and event-free survival (EFS) for the whole series were 51.7+/-8%, 34+/-9% and 28+/-8%, with a median follow-up for the surviving patients of 3 years (0.7-7.6). No differences in these survival functions according to the CBV regimen used were observed (P=0.57). A history of a prior CR (P=0.003), duration of first CR >1 year (P=0.04), absence of bulky nodal disease at transplant (P=0.054), absence of extranodal disease at transplant (P=0.01), and a CR status at transplant (P=0.0006) were associated with a better PFS on univariant analysis. On multivariate analysis, only CR status at transplant remained significant (P=0.05). When patients in second CR at transplant and those in first sensitive relapse were analyzed separately, no differences in clinical characteristics or in treatment received pretransplant were observed; however, PFS was significantly different (P=0.01). In conclusion, CR status at transplant is useful in identifying 'good risk' patients and is necessary to obtain the greatest benefit from ASCT independent of the CBV regimen used.     

Non-Hodgkin's lymphoma

Attention is being directed at increasing the intensity of therapy as a means of improving the results of primary therapy for non-Hodgkin's lymphoma. There is increasing evidence that the use of high-dose consolidation therapy followed by autologous hematopoietic rescue in first remission improves survival in high-risk patients. There is also evidence from randomized trials that transplantation for relapsed patients improves survival compared with conventional salvage chemotherapy. Phase II trials of radiolabeled antibody therapy are providing promising results. There is still no definitive evidence that any treatment of advanced low-grade lymphoma prolongs survival, although the use of allogeneic bone marrow transplantation is under investigation. Treatment designed to eradicate Helicobacter pylori can cause regression in approximately 50% of patients with gastric lymphomas of mucosa-associated lymphoid tissue, although long-term follow-up information is lacking. The results of treatment for mantle cell lymphoma are poor and there is no consensus on management. Most trials of primary central nervous system lymphoma are employing systemic chemotherapy with drugs that penetrate the blood-brain barrier in addition to radiation.     

A randomized comparison of the efficacy and toxicity of epirubicin and doxorubicin in the treatment of patients with non-Hodgkin's lymphoma

BACKGROUND: Combination chemotherapy consisting of methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisolone, and bleomycin (MACOP-B) has been frequently used for the treatment of non-Hodgkin's lymphoma. This randomized study was undertaken to assess the efficacy and toxicity of this regimen when either doxorubicin or epirubicin was used as the anthracycline drug. METHODS: Between April 1989 and December 1993, 211 previously untreated patients with intermediate grade and high grade non-Hodgkin's lymphoma were randomized to receive either doxorubicin (n=106) or epirubicin (n=105) with the MACOP-B regimen. These patients were followed through December 1996. Numerous clinical features predictive of response and survival were analyzed. Cardiac and noncardiac toxicity in the two treatment arms were compared. RESULTS: The median age of the patients was 48 years. Complete remission was experienced by 122 patients (58.3%); 62 patients (58.5%) achieved complete remission in the doxorubicin arm and 60 (58.1%) in the epirubicin arm. Response rates, time to treatment failure, relapse data, and overall survival were comparable between the two arms. Morbidity due to mucositis, vomiting, peripheral neuropathy, and cardiotoxicity were also comparable. The overall mortality was 10%. Mortality due to neutropenic sepsis was considerably higher among patients who received epirubicin (10 patients) than among those who received doxorubicin (5 patients). Cardiac evaluation revealed no difference in toxicity between the two arms. CONCLUSIONS: Epirubicin was as effective as doxorubicin in terms of patients' responses to therapy. There was no difference in cardiotoxicity between the two treatment arms. However, in this study, the mortality due to neutropenic sepsis was significantly higher among patients treated with epirubicin.     

The MACOP-B and VACOP-B combination chemotherapy for young patients with intermediate-grade non-Hodgkin's lymphoma

Since the early 1970s, three generations of combination chemotherapy for intermediate-grade non-Hodgkin's lymphomas (NHL) have been developed. One of the third-generation regimens is MACOP-B (methotrexate, doxorubicin, cyclophosphamide, vincristine, prednisone, and bleomycin). The VACOP-B regimen is a modification of MACOP-B in which methotrexate is omitted and etoposide is added. This study assesses treatment outcome using the MACOP-B and VACOP-B combination chemotherapy in a population of young patients with intermediate-grade NHL treated in a single tertiary hematological center. The files of 45 patients aged 18-55 who were diagnosed as having intermediate-grade NHL (working formulation types F-H) and treated between January 1986 and March 1994 were reviewed. Treatment response, overall survival, disease-free survival and treatment toxicity were determined. The predictive value of the age-adjusted international prognostic index was also assessed. Median follow-up was 80 months in the MACOP-B group and 29 months in the VACOP-B group. The complete response rate was 71% (95% confidence interval CI: 58-84), 4-year overall survival was 74 +/- 7% and 4-year disease-free survival was 79 +/- 8%. No toxicity-related deaths were observed. The main adverse effects were WHO grade 3 or 4 neutropenia (51%), anemia (24%) and mucositis (20%). Only the CR rate was correlated with the Age-Adjusted International Prognostic Index. Mean relative dose intensity was high (95.7%, 95%) CI: 91.7-99.7) and had no correlation with treatment outcome. The MACOP-B and VACOP-B combination chemotherapy regimens were found to be effective and minimally toxic for young patients up to 55 years old with intermediate-grade NHL.
