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. 相似文献

PURPOSE: The HD9 trial aims to evaluate whether moderate dose escalation and/or acceleration of standard polychemotherapy is beneficial for advanced-stage Hodgkin's disease (HD). Two variants of a novel bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) scheme (standard and escalated dose) are compared with cyclophosphamide, vincristine, procarbazine, and prednisone (COPP)/doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD). PATIENTS AND METHODS: The randomized, three-arm trial recruited patients in stages IIB and IIIA with risk factors and stages IIIB and IV. BEACOPP in baseline dose contains all drug dosages of COPP/ABVD (except vincristine and procarbazine) rearranged in a shorter, 3-week cycle. Escalated BEACOPP uses higher doses of cyclophosphamide, doxorubicin, and etoposide with granulocyte colony-stimulating factor (G-CSF) support. After eight chemotherapy cycles, initial bulky and residual disease is irradiated. The trial is monitored and analyzed by means of a sequential strategy. RESULTS: An interim analysis with 505 assessable patients and a median follow-up of 23 months showed a significant inferiority (according to sequential monitoring strategy) of the COPP/ABVD regimen in progression rate and freedom from treatment failure (FFTF) compared with the pooled results of both BEACOPP variants. The 24-month FFTF rate was 75% for COPP/ABVD and 84% for BEACOPP pooled (P = .034). There was 12% progressive disease with COPP/ABVD and 6% with BEACOPP pooled. Differences in survival were not significant in sequential analysis. The acute toxicity of baseline BEACOPP resembled that of COPP/ABVD; escalated BEACOPP showed increased but manageable hematologic toxicity. CONCLUSION: Combined with local irradiation, BEACOPP in one or both variants shows superior disease control compared with COPP/ABVD, with acceptable acute toxicity. Further follow-up is required to assess the effect of dosage and the effect on survival and late toxicities. 相似文献

PURPOSE: To evaluate the therapeutic significance of cisplatin, vincristine, doxorubicin, and etoposide (CODE) plus granulocyte colony-stimulating factor (G-CSF) compared with cyclophosphamide, doxorubicin, and vincristine, alternating with cisplatin and etoposide (CAV/PE) for extensive-disease (ED) small-cell lung cancer (SCLC). PATIENTS AND METHODS: Two hundred twenty-seven patients were randomized. CODE consisted of cisplatin 25 mg/m2 weekly for 9 weeks; vincristine 1 mg/m2 on weeks 1, 2, 4, and 6; and doxorubicin 40 mg/m2 and etoposide 80 mg/m2 for 3 days on weeks 1, 3, 5, 7, and 9. G-CSF 50 micrograms/m2 was administered on the days when chemotherapy was not administered. CAV/PE consisted of cyclophosphamide 800 mg/m2; doxorubicin 50 mg/m2; and vincristine 1.4 mg/m2 on day 1, which alternated every 3 weeks with cisplatin 80 mg/m2 on day 1 and etoposide 100 mg/m2 on days 1 to 3. RESULTS: Overall response rates were 77% for the CAV/PE arm and 84% for the CODE arm respectively (15% complete response in both arms). The median survival times were 10.9 months in the CAV/PE arm and 11.6 months in the CODE arm (P = .1034). The achieved dose-intensity for CODE was approximately twice that for CAV/PE for those drugs common to both arms. The incidence of leukopenia did not differ between the two arms, but anemia and thrombocytopenia had a significantly higher incidence in the CODE arm. Four treatment-related deaths from neutropenic fever occurred in the CODE arm. CONCLUSION: The CODE group had a similar median survival to the CAV/PE group. It does not appear that CODE is a useful approach to improve survival in ED SCLC. 相似文献

BACKGROUND: Testicular dysfunction with elevated follicle-stimulating hormone (FSH) levels (indicating oligospermia and/or azoospermia) is a major late sequelae after treatment for Hodgkin's disease (HD) with high cumulative doses of procarbazine, cyclophosphamide, or chlorambucil. Etoposide is a newer antineoplastic agent that is effective in the treatment of HD. However, little is known regarding its testicular toxicity, especially in the pediatric age group. METHODS: The authors evaluated testicular function in 46 young adults in first continuous complete remission after stage-dependent treatment for HD with the vincristine, etoposide, prednisone, and doxorubicin (OEPA) or OEPA/cyclophosphamide, vincristine, procarbazine, and prednisone [COPP] chemotherapy regimens and involved field irradiation, excluding patients with ilioinguinal radiotherapy. Pubertal development was documented and a standardized intravenous gonadotropin-releasing hormone test was performed measuring testosterone and basal and stimulated levels of FSH and luteinizing hormone (LH). RESULTS: Testicular volumes, Tanner stages of pubic hair, and genital development were found to be appropriate or slightly delayed for the patients' chronologic age. All 27 patients had normal basal levels of FSH and LH after treatment of Ann Arbor Stage I-IIA HD with 2 courses of OEPA. Stimulated FSH and LH levels were found to be elevated only in rare patients, thus indicating normal endocrine function and spermatogenesis. However, basal and stimulated FSH levels were outside the +2 standard deviation range in 37.5% and 83.3% of patients receiving 2 cycles of OEPA and 2 cycles of COPP chemotherapy, and in 36.4% and 66.7% of patients receiving 2 cycles of OEPA and 4 cycles of COPP chemotherapy, demonstrating a high risk of oligospermia or azoospermia with these regimens. Basal LH levels essentially were normal, whereas stimulated LH levels frequently were elevated. CONCLUSIONS: Testicular function was found to be normal in patients with Stage I-IIA HD when etoposide was used in combination with vincristine, prednisone, and doxorubicin (2 cycles of OEPA). Additional chemotherapy with cyclophosphamide and procarbazine (2 cycles of OEPA and 2 or 4 cycles of COPP) negatively affected spermatogenesis and possibly Leydig cell function in a considerable number of patients. This major gonadotoxic effect most likely is due to procarbazine, although an additional effect of etoposide and cyclophosphamide cannot be excluded. 相似文献

The role of ifosfamide as first-line chemotherapy treatment of non metastatic Ewing's sarcoma of the extremity is still under discussion. The purpose of this paper is to report the results achieved in a neoadjuvant protocol (REN-3) in which ifosfamide, added to the conventional VACA regimen, was employed since the induction phase. Induction chemotherapy consisted of vincristine, cyclophosphamide, doxorubicin, actinomycin-D and ifosfamide. After local treatment, patients received the drugs used in the induction phase and etoposide. Between November 1991 and November 1994, 61 patients with non metastatic Ewing's sarcoma of the extremity were treated. Forty-nine patients underwent surgery and 73.5% of them had a good histologic response. At a median follow-up of 60 months (range 32-76), 48 patients (79%) remained continuously disease-free. The 5-year event-free and overall survival were 77% and 87%, respectively. These results were significantly better both in terms of histologic response or event-free and overall survival than those obtained in 58 patients with non metastatic Ewing's sarcoma of the extremity treated in a previous protocol (REN-2) in which the same drugs were used, but ifosfamide was employed only in the maintenance phase. The present study suggests the importance of early use of ifosfamide in the treatment of patients with non metastatic Ewing's sarcoma of the extremity. 相似文献

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. 相似文献

PURPOSE: The primary objectives of the study were to evaluate the efficacy and safety of prolonged oral (PO) etoposide as part of cisplatin-based chemotherapy plus concurrent chest/brain irradiation induction, followed by CAV consolidation, in the treatment of patients with limited-stage small cell lung cancer (SCLC-LD) within a cooperative group setting. METHODS AND MATERIALS: Fifty-six eligible patients with SCLC-LD received three 28-day cycles of cisplatin 50 mg/m2 i.v. (days 1, 8; 29, 36; and 57, 64), PO etoposide 50 mg/m2 (days 1-14, 29-42, and 57-70), and vincristine 2 mg i.v. (days 1, 29, and 57). Thoracic irradiation (TRT) was administered at 1.8 Gy in 25 daily fractions to a total dose of 45 Gy via an AP:PA arrangement, to begin concomitantly with induction chemotherapy. Prophylactic cranial irradiation (PCI) was started on day 15 of induction therapy. Fifteen daily fractions of 2.0 Gy were administered to the entire brain to a total dose of 30 Gy to finish at approximately the same time as TRT. Two 21-day cycles of consolidation cyclophosphamide 750 mg/m2 i.v., doxorubicin 50 mg/m2 i.v., and vincristine 2 mg i.v. (all on days 1 and 22), were given beginning on day 106 or week 16, from the start of induction therapy. RESULTS: Among 56 eligible patients, 93% had SWOG performance status 0-1. All had adequate organ function and had not received prior therapy. The overall confirmed response rate was 46%, including 16% complete responders and 30% partial responders. After a minimum follow-up duration of 17 months, the Kaplan-Meier median progression-free (PFS) and overall survival (OS) were 10 and 15 months, respectively. Two-year survival is 28%. Only 28 of 56 patients (50%) completed chemotherapy per protocol, while 52 of 56 patients (93%) completed radiation per protocol. Eleven patients (20%) discontinued secondary to toxicity and two patients died from treatment. The major toxicity was hematologic. The two deaths were secondary to infection. Of the nonhematologic toxicities, there were 10 cases of pulmonary fibrosis (including one Grade 3) and six cases of pneumonitis (including one Grade 3). CONCLUSION: Concomitant chemoradiation with oral etoposide as part of a platinum-based chemotherapy and TRT induction regimen is toxic. The CR rate is not better than our prior best group-wide experience. The progression-free and overall survival are similar to published trials utilizing short-course i.v. etoposide. As in chemotherapy for extensive-stage SCLC, there is no apparent advantage to prolonged exposure to etoposide, and toxicity resulted in an inferior therapeutic index compared to programs with shortened exposure. 相似文献

PURPOSE: A regimen of cisplatin, doxorubicin, vincristine, and etoposide (PAVE) was designed for patients with small-cell lung cancer (SCLC) who were older than 65 years, with the following objectives compared with standard chemotherapy regimens: maintain efficacy, diminish toxicity, enhance compliance, and improve chemotherapy administration convenience at an acceptable cost. PATIENTS AND METHODS: The PAVE regimen consisted of cisplatin 30 mg/m2 intravenously (i.v.) day 1; doxorubicin 40 mg/m2 i.v. day 1; vincristine 1.0 mg/m2 i.v. day 1; and etoposide 100 mg/m2 i.v. day 1 and orally days 3 and 5. Cycles were repeated every 3 weeks for four cycles. Patients with limited-stage disease and selected patients with extensive-stage disease received thoracic irradiation delivered concurrently with etoposide-cisplatin (EP) at the time of the second chemotherapy cycle. RESULTS: Sixty-six eligible patients were treated, which included 25 patients with limited-stage disease and 41 patients with extensive-stage disease. Median survival was 70 weeks and 5-year survival was 25% for limited-stage disease. Median survival was 46 weeks for extensive-stage disease. Only one treatment-related death occurred and severe toxicity was infrequent. The median delivered dose-intensity was according to protocol and the mean delivered total dose was 80% of intended. CONCLUSION: The treatment outcome achieved with PAVE in a phase II study of elderly patients compared favorably with published results of standard regimens in patient populations with better prognostic factors. Because the PAVE regimen can be delivered with good compliance, has acceptable toxicity, and is associated with logistic advantages compared with standard regimens, this protocol is suitable for further investigative trials in elderly patients with SCLC. 相似文献

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. 相似文献

Between 1984-1987, 50 patients with Ewing's sarcoma of the bone were entered on combined modality protocol at Tata Memorial Hospital. Protocol treatment involved induction therapy consisting of 6-week therapy with vincristine, Adriamycin (doxorubicin), and cyclophosphamide (VDC) followed by local radiotherapy 50 Gy to the involved bone. This was followed for six more cycles of VDC. Five patients had metastatic disease at presentation. Seventy-six percent (38/50) of patients had disease either at axial or proximal site. With a median follow-up of 48 months (range 14-87) 21 patients remained alive with disease-free survival of 38.0% +/- 2.5% at 5 years and overall survival of 36.0% +/- 2.6% at 5 years. Twenty-five patients relapsed with five patients developing local failure and four local and distant metastasis. Using Lee-Desu statistical methods, only response to therapy was a significant factor for survival. We conclude that more aggressive therapy with proper selection of local treatment modality including surgery and/or radiotherapy is required to produce more long-term survival in high-risk Ewing's sarcoma. 相似文献

Children with acute lymphoblastic leukemia (ALL) who have completed 2.5 to 3 years of initial chemotherapy have an off-therapy relapse rate of approximately 20%. In an attempt to improve the survival of children with a late bone marrow (BM) relapse (ie, occurring greater than 6 months after cessation of primary therapy), the Pediatric Oncology Group designed a randomized study to compare the efficacy of doxorubicin/prednisone and cytarabine/teniposide in a multidrug retreatment chemotherapy program. Treatment consisted of remission reinduction with vincristine, prednisone, and doxorubicin, central nervous system prophylaxis with triple intrathecal chemotherapy, and continuation therapy (for 132 weeks) with alternating cycles of oral 6-mercaptopurine/methotrexate and intravenous vincristine/cyclophosphamide. Patients received intermittent courses of either prednisone/doxorubicin (regimen 1) or teniposide/cytarabine (regimen 2) during continuation therapy and a late intensification phase with either vincristine, prednisone, and doxorubicin (regimen 1) or teniposide and cytarabine (regimen 2). One hundred two of 105 evaluable patients (97%) achieved a second complete remission. Twenty-eight of 50 patients on regimen 1 have failed compared with 28 or 52 patients on regimen 2 (log-rank analysis, P = .68), indicating that this trial was inconclusive as to which treatment regimen was superior. The overall 4-year event-free survival for children with a late BM relapse was 37% +/- 6%. Age less than 10 years at initial diagnosis (P < or = .001), white blood cell count less than 5,000/microL at relapse (P = .036) and duration of first remission greater than 54 months (P = .039) were independently associated with a more favorable outcome. While the randomized trial was inconclusive, prolonged second complete remissions were secured in more than one-third of children with a late BM relapse of ALL. The prognostic factors identified may help select children with a late BM relapse who can be successfully retreated with chemotherapy alone. 相似文献

BACKGROUND: Patients with inflammatory breast cancer have a high risk of developing a local recurrence and/or distant metastases. Treatment with combined chemotherapy and locoregional radiotherapy contributes to a decrease in both risks. This study presents treatment results and evaluates the pattern of failure when an alternating chemoradiotherapy schedule is used. METHODS: One hundred twenty-five patients with nonmetastatic inflammatory breast cancer were treated with an alternating schedule of radiotherapy and chemotherapy. All women recruited were younger than 70 years of age and had a T4d, histologically proven infiltrating carcinoma with N0 to N2 axillary disease. The protocol consisted of three cycles of induction chemotherapy with doxorubicin, vincristine, cyclophosphamide, methotrexate, and 5-fluorouracil followed by three series of locoregional radiotherapy, delivering a total dose of 65-75 Gy to the breast tumor. Five additional cycles of chemotherapy with 5-fluorouracil/doxorubicin/cyclophosphamide were to be administered in between the first two and after the third radiotherapy course. A 1-week gap was respected between each course of chemotherapy and each series of radiotherapy. RESULTS: Toxicity was moderate and this strategy proved feasible although most of the patients only received six instead of the eight planned cycles of chemotherapy. Eighty-two percent of the patients achieved a complete response at the end of the treatment. The cumulative 5-year local failure and distant metastasis rates were 27% and 53%, respectively. Assuming competing events, local failures, contralateral recurrences, and distant metastases were the first site of failure in 18%, 5%, and 38% of patients, respectively. The 5-year overall and disease free survival rates were 50% and 38%, respectively. The main prognostic factor was tumor size. CONCLUSIONS: Alternating high doses of radiotherapy and chemotherapy is a feasible treatment schedule and permits breast conservation. Disease free survival is comparable to that of recently published series. As the main causes of failure are distant metastases, higher dose chemotherapy should be evaluated, in an attempt to further improve overall survival. 相似文献

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. 相似文献

The effects of a combination chemotherapy (CAV-PVP) consisting of cyclophosphamide, doxorubicin, hydrochloride (dox) and vincristine (CAV) alternating with cisplatin and etoposide (PVP) on peripheral blood hematopoietic progenitor cells (PBHPs) were studied in five patients with small cell lung cancer (SCLC). The kinetics of the CFU-GM levels were different during the CAV and PVP phases. None of the five patients displayed a rebound increase in the level of peripheral blood CFU-GM during the CAV phase. In contrast, all five patients displayed a rebound increase in peripheral blood CFU-GM levels during the PVP phase of the alternative combination chemotherapy (3-5 weeks after the initiation of PVP regimen). These findings indicate the optimal timing for leukapheresis to obtain PBHPs in SCLC patients which have been treated with an alternating combination chemotherapy consisting of CAV-PVP. 相似文献

BACKGROUND: The objectives of this study were to compare vincristine/actinomycin D/cyclophosphamide/adriamycin (VACA) with VACA/plus imidazole carboxamide (DTIC) (VACAD) therapy in regards to complete/partial response and event free survival rates in children and adolescents with metastatic non-rhabdomyosarcoma soft tissue sarcomas (NRSTS) or previously chemotherapy-naive recurrent NRSTS or locally persistent gross residual tumor after surgery and radiation therapy. PROCEDURES: Between 1986 and March 1994, 75 patients entered this randomized study comparing VACA and VACAD, given at 3 week intervals. Sixty-one patients were considered eligible and received chemotherapy and radiation therapy to the primary tumor and areas of metastases. Thirty-six patients had regional unresected (Group III) disease, and 25 had metastatic disease (Group IV) at time of accession. Thirty-six patients received VACA (11 were not randomized), and 25 received VACAD. RESULTS: With a median follow-up of greater than 4 years, overall and event-free survival for all eligible patients are 30.6% and 18.4% respectively (S.E: 9.5% and 6.8%). There was insufficient evidence that DTIC offered any advantage to event free survival, but there was evidence for better outcome for patients in Group III disease in comparison to patients with Group IV disease, and for patients with a Grade 1 and 2 histology in comparison to Grade 3 lesions. CONCLUSIONS: Combination chemotherapy with VACA and VACAD were insufficient to prevent recurrent or progressive disease in children and adolescents with high stage NRSTS. The use of vincristine/ifosfamide/doxorubicin with cytokine support is under study. 相似文献

PURPOSE: To investigate the possibility that the substitution of ifosfamide for cyclophosphamide therapy for Ewing's sarcoma will improve survival over that seen in the first United Kingdom Children's Cancer Study Group (UKCCSG) Ewing's tumor study (ET-1). PATIENTS AND METHODS: Between 1987 and 1993,243 patients (138 men or boys) were entered onto the study. The median age was 13.5 years (range, 1.5 to 27 years). The median follow-up was 58 months. Chemotherapy included four courses of vincristine 2 mg/m2; ifosfamide 9 g/m2; and doxorubicin 60 mg/m2 administered every 3 weeks. Treatment of the primary tumor was with surgery and/or radiotherapy followed by ifosfamide 6 g/m2; doxorubicin 60 mg/m2; and vincristine 2 mg/m2; with actinomycin D 1.5 mg/m2 substituted for doxorubicin after a total dose of 420 mg/m2. RESULTS: Two hundred one patients had no metastases. One hundred eighteen patients had tumors of the axial skeleton and 125 patients had limb primary tumors. The major toxicities were hematologic and infective, but there were no toxic deaths. The overall survival rate was 62% (95% confidence interval [CI], 56 to 69) and relapse-free survival (RFS) 56% (95% CI, 49 to 62). For those with no metastases at diagnosis, the RFS rate was 62% and for those with metastases, 23%. Multivariate analysis showed age and site to have a significant effect on RFS. Pelvic sites had the worst RFS rate of 41%; other axial sites, 55%; and extremity tumors, 73%. Age younger than 10 years had an RFS rate of 86% versus 55% for older patients. The local relapse rate for axial tumors was 20% and for limb primary tumors was 2.4%. CONCLUSION: The 5-year survival rate of 62% is improved compared with the 44% survival rate achieved in ET-1. This is probably caused by the use of higher doses of ifosfamide compared with relatively low doses of cyclophosphamide in ET-1. 相似文献

AIMS AND BACKGROUND: Ifosfamide is an active alkylating agent in the treatment of breast cancer, as a first-line therapy and in advanced disease. Since the combination of etoposide with an alkylating agent produces a synergistic and tolerable activity in various malignancies, in the present study, ifosfamide and etoposide were administered to patients with advanced breast cancer to evaluate the response characteristics and the toxicity profile. STUDY DESIGN: The combination of ifosfamide, mesna and etoposide was prospectively administered to 41 previously treated patients with stage IV breast carcinoma. The treatment schedule consisted of ifosfamide, 1500 mg/m2, infused over 24 hrs with 1500 mg/m2 mesna on days 1 to 5 and 120 mg/m2 etoposide, infused over 1 hr on days 1 to 3, to be repeated every 4th week. RESULTS: After a median follow-up of 10 months, an objective response rate of 23% (overall 2.5% complete remission and 20.5% partial remission) and a median response duration of 5.3 months were obtained in 39 assessable patients. The non-responder group consisted of 28.3% stable disease and 48.7% progressive disease. The prior status of chemotherapy was the only significant prognostic factor with an impact on the response rate. The overall toxicity was generally mild, with grade 3 myelotoxicity encountered in 25.7% of patients. CONCLUSIONS: The tolerable side effect profile of the ifosfamide and etoposide combination might be advantageous as regards the quality of life. To improve the rate and/or the duration of response and to clarify the precise role of the ifosfamide-etoposide combination in previously treated advanced breast cancer, further trials are warranted. 相似文献

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. 相似文献

To evaluate the efficacy of systemic ifosfamide, cisplatin (CDDP) combination as first line treatment followed by intraperitoneal (IP) chemotherapy with carboplatin (CBCDA) and etoposide as consolidation in patients with stage III and IV epithelial ovarian cancer. A total of 40 patients with stage III and IV ovarian cancer were entered into the study. Ifosfamide 1 g/m2 plus mesna 1 g/m2 was given as six hour infusion daily for six days and CDDP 75 mg/m2 was given on day seven. Patients completing six cycles of systemic therapy underwent second look laparotomy followed by four cycles of IP chemotherapy with CBCDA 300 mg/m2 and etoposide 200 mg/m2. Of the 40 patients entering the protocol 27 patients completed six cycles with a complete remission (CR) of 65% and overall response of 67.5%. Twenty-two patients underwent second look laparotomy with pathological CR in ten patients, microscopic disease in seven and macroscopic disease in five. Eleven patients completed four cycles of IP chemotherapy. At 52 months was the overall survival (OS) was 36%. The disease free survival (DFS) at 45 months was 38%. Factors affecting OS were ascites (p < 0.011), stage (p < 0.04), weight change (p < 0.017), residual disease (p < 0.001), number of chemotherapy cycles (p < 0.0001) and IP chemotherapy (p < 0.006). Presently 35% patients are alive in CR, 15% are alive with disease, one patients has been lost to follow up while 47.5% have died. Of these four patients had progressive disease, seven relapsed, four died due to treatment related complications and two died in CR due to other causes. Subset analysis of 22 patients who had second look laparotomy and completed four cycles of IP chemotherapy revealed a distinct survival advantage. IFOS + CDDP is an effective combination as first time treatment in advanced ovarian cancer. IP chemotherapy is effective as consolidation and seems to provide a significant survival advantage. Further studies with larger number of patients need to be done to confirm these results. 相似文献

The BEACOPP (bleomycin, etoposide, adriamycin, cyclophosphamide, vincristine, procarbazine, and prednisone) regimen, a rearranged and accelerated version of the standard COPP/adriamycin, bleomycin, vinblastine, and dacarbazine (ABVD) chemotherapy, has been shown to be effective and safe in a previous pilot study for advanced stage Hodgkin's disease (HD). The present study aimed to determine a maximum practicable dose of three drugs, ie, etoposide, adriamycin, and cyclophosphamide, for which acute toxicities were acceptable and to assess the feasibility of the escalated scheme. Sixty untreated patients with advanced stage HD were enrolled in this study. Radiotherapy was given in 44 patients (73%) after chemotherapy to initial bulk lesions and residual disease. Granulocyte-colony stimulating factor (G-CSF) was given from day 8 to prevent prolonged neutrocytopenia and severe infections. The intended doses of adriamycin, etoposide, and cyclophosphamide in the BEACOPP schedule could be substantially escalated: adriamycin from 25 to 35, cyclophosphamide from 650 to 1,200, and etoposide from 100 to 200 mg/m2. The major toxicities were leukocytopenia and thrombocytopenia with considerable heterogeneity between individual patients. Of 60 patients, 56 (93%) achieved a complete remission (CR). At a median observation of 32 months, the rates of survival and freedom from treatment failure (FFTF) were estimated to be 91% (95% confidence interval 83% to 99%) and 90% (82% to 98%). These results show that a moderate dose escalation of adriamycin, cyclophosphamide, and etoposide of the baseline BEACOPP regimen is feasible. The escalated BEACOPP regimen shows very encouraging results in advanced stage HD and is now being compared in a randomized phase III study with BEACOPP at baseline dose level. 相似文献
