PURPOSE Because the effects of mitoxantrone on human male fertility were unknown, we determined prospectively the effects of three courses of mitoxantrone (Novantrone), vincristine (Oncovin), vinblastine, prednisone (NOVP) chemotherapy on the potential for fertility of men with Hodgkin's disease (HD). PATIENTS AND METHODS Semen analyses were performed on 58 patients with stages I-III HD before, during, and after chemotherapy and after the sperm count recovered from the effects of abdominal radiotherapy that was given after chemotherapy. RESULTS Before the initiation of treatment, 84% of the patients were normospermic. Sperm counts declined significantly within 1 month after the start of NOVP chemotherapy. In the month after chemotherapy, 38% of patients were azoospermic, 52% had counts < 1 million/ mL, and 10% had counts between 1 and 3 million/mL. Between 2.6 and 4.5 months after the completion of chemotherapy, sperm counts recovered rapidly to normospermic levels in 63% of patients. In the remaining patients who were followed up for at least 1 year after standard upper abdominal radiotherapy, counts also recovered to normospermic levels. CONCLUSION NOVP chemotherapy, like most other regimens, produced marked temporary effects or spermatogenesis. However, sperm production recovered very rapidly, within 3 to 4 months after the end of NOVP chemotherapy. This pattern was caused by killing differentiating spermatogenic cells, but there was little cytotoxicity or inhibition of stem cells from mitoxantrone or the other drugs. After the combination of NOVP plus abdominal radiotherapy, sperm counts and motility were restored in most patients to pretreatment levels, which were compatible with normal fertility.

PURPOSE The hematopoietic growth factors (HGFs) introduced into induction chemotherapy (CT) of acute myeloid leukemia (AML) might be of benefit to treatment outcome by at least two mechanisms. HGFs given on days simultaneously with CT might sensitize the leukemic cells and enhance their susceptibility to CT. HGFs applied after CT might hasten hematopoietic recovery and reduce morbidity or mortality. MATERIALS AND METHODS We set out to evaluate the use of granulocyte-macrophage colony-stimulating factor (GM-CSF; 5 microg/kg) in a prospective randomized study of factorial design (yes or no GM-CSF during CT, and yes or no GM-CSF after CT) in patients aged 15 to 60 years (mean, 42) with newly diagnosed AML. GM-CSF was applied as follows: during CT only (+/-, n = 64 assessable patients), GM-CSF during and following CT (+/+, n = 66), no GM-CSF (-/-, n = 63), or GM-CSF after CT only (-/+, n = 60). RESULTS The complete response (CR) rate was 77%. At a median follow-up time of 42 months, probabilities of overall survival (OS) and disease-free survival (DFS) at 3 years were 38% and 37% in all patients. CR rates, OS, and DFS did not differ between the treatment groups (intention-to-treat analysis). Neutrophil recovery (1.0 x 10(9)/L) and monocyte recovery were significantly faster in patients who received GM-CSF after CT (26 days v 30 days; neutrophils, P < .001; monocytes, P < .005). Platelet regeneration, transfusion requirements, use of antibiotics, frequency of infections, and duration of hospitalization did not vary as a function of any of the therapeutic GM-CSF modalities. More frequent side effects (eg, fever and fluid retention) were noted in GM-CSF-treated patients predominantly related to the use of GM-CSF during CT. CONCLUSION Priming of AML cells to the cytotoxic effects of CT by the use of GM-CSF during CT or accelerating myeloid recovery by the use of GM-CSF after CT does not significantly improve treatment outcome of young and middle-aged adults with newly diagnosed AML.

PURPOSE Euthanasia is a pressing public issue. We sought to assess how frequently physicians could perceive of a desire for euthanasia themselves and whether they would be willing to provide patients the same interventions. METHODS We interviewed 355 randomly selected oncologists from the United States and interviewed them about their attitudes and practices related to euthanasia and assisted suicide. RESULTS Of the 355 oncologists, 48.1% could imagine a situation in which they might desire euthanasia or assisted suicide for themselves. Oncologists who were Catholic and more religious were significantly less likely to desire these interventions for themselves. Of those oncologists who could imagine a situation in which they might desire euthanasia or assisted suicide for themselves, 85.8% found euthanasia and/or assisted suicide acceptable for their patients. Of the oncologists who could not imagine a situation in which they might desire euthanasia or assisted suicide for themselves, 41.7% still found these interventions ethical for their patients. Only 6.8% of oncologists could imagine a situation in which they might desire euthanasia or assisted suicide for themselves but found these interventions unacceptable for their patients. CONCLUSION Almost half of surveyed oncologists could imagine a situation in which they would desire euthanasia or assisted suicide. However, in many cases, this was for nonterminal illness which would be prohibited by proposed laws. When physicians desire euthanasia or assisted suicide for themselves, they are willing to provide these interventions for their patients; therefore, most physicians would practice what they preach. Indeed, when they deviate, oncologists overwhelmingly respect patient autonomy rather than impose their own views on patients.

PURPOSE Recipients of allogeneic bone marrow transplants (BMTs) who have relapsed may attain complete remissions when treated with transfusions of leukocytes obtained from the original bone marrow donor. We performed a retrospective study to characterize better this new treatment modality. PATIENTS AND METHODS We surveyed 25 North American BMT programs regarding their use of donor leukocyte infusions (DLI). Detailed forms were used to gather data regarding the original BMT, relapse, DLI, response to DLI, complications of DLI, and long-term follow-up evaluation. Reports of 140 patients were thus available for analysis. RESULTS Complete responses were observed in 60% (95% confidence interval [CI], 51.9% to 68.1%) of chronic myelogenous leukemia (CML) patients who received DLI and did not receive pre-DLI chemotherapy; response rates were higher in patients with cytogenetic and chronic-phase relapse (75.7%; 95% CI, 68.2% to 83.2%) than in patients with accelerated-phase (33.3%; 95% CI, 19.7% to 46.9%) or blastic-phase (16.7%; 95% CI, 1.9% to 31.9%) relapse. The actuarial probability of remaining in complete remission at 2 years was 89.6%. Complete remission rates in acute myelogenous leukemia (AML) (n = 39) and acute lymphocytic leukemia (ALL) (n = 11) patients who had not received pre-DLI chemotherapy were 15.4% (95% CI, 9.6% to 21.2%) and 18.2% (95% CI, 6.6% to 29.8%), respectively. Complete remissions were also observed in two of four assessable myeloma patients and two of five assessable myelodysplasia patients. Complications of DLI included acute graft-versus-host disease (GVHD) (60%; 95% CI, 51.4% to 68.6%), chronic GVHD (60.7%; 95% CI, 50.3% to 71.1%), and pancytopenia (18.6%; 95% CI, 12.2% to 25.0%). Pre-DLI characteristics predictive of complete response in CML patients were post-BMT chronic GVHD, pre-DLI disease status of chronic phase, and time interval between BMT to DLI less than 2 years. Acute and chronic GVHD post-DLI were highly correlated with disease response (P < .00001). CONCLUSION DLI results in complete remissions in a high percentage of patients with relapsed chronic-phase CML. Complete remissions are observed less frequently in patients with advanced CML and acute leukemia. GVHD and pancytopenia occur commonly; GVHD is highly correlated with response.

PURPOSE To examine the prognostic significance of extramedullary leukemia (EML) at presentation in patients with t(8;21)(q22;q22) karyotype. PATIENTS AND METHODS Consecutive patients with t(8;21) treated on Cancer and Leukemia Group B de novo acute myeloid leukemia (AML) treatment studies were examined for the presence of EML (granulocytic sarcoma, subcutaneous nodules, leukemia cutis, or meningeal leukemia) at initial presentation. Clinical features and outcome of t(8;21) patients with and without EML were compared. RESULTS Of 84 patients with t(8;21), eight (9.5%) had EML manifesting as granulocytic sarcoma (five paraspinal, one breast, and one subcutaneous) or symptomatic meningeal leukemia (n = 1). The pretreatment prognostic variables of t(8;21) patients with and without EML were similar. The hematologic complete remission (CR) rate for t(8;21) patients with EML was 50% versus 92% for those without EML (P=.006). The median CR duration for EML patients was 14.7 months. Patients with EML had a shorter survival (P = 0.002, median 5.4 months versus 59.5 months). This poor outcome may relate to inadequate local (radiation or intrathecal) therapy for patients with spinal or meningeal EML, resulting in residual/recurrent EML following induction chemotherapy (n = 2) or at relapse (n = 1) and permanent neurologic deficits (n = 4). Only one of the EML patients received high-dose cytarabine (HDAC) intensification; this is the only EML patient remaining alive in CR. CONCLUSION Patients with t(8;21) and EML have a low CR rate and overall survival. An aggressive local and systemic induction therapy should be considered for this patient subset. The effectiveness of HDAC intensification in t(8;21) patients with EML is uncertain and warrants further study.

PURPOSE To investigate the value of intensive consolidation chemotherapy not followed by maintenance therapy in adult acute lymphoblastic leukemia (ALL). MATERIALS AND METHODS A multicenter phase II trial was conducted in 130 adult patients with ALL between 16 and 60 years of age. After standard induction therapy, postinduction chemotherapy was given: three courses of high-dose cytarabine (2,000 mg/m2 every 12 hours for four doses) in combination with amsacrine (course one), mitoxantrone (course two), and etoposide (course three). CNS prophylaxis consisted of 10 injections of intrathecal methotrexate (IT MTX). Patients younger than 50 years with an HLA-identical sibling were eligible to receive allogeneic bone marrow transplantation (BMT). RESULTS Ninety-five patients (73%) achieved complete remission (CR); 82% were younger than 50 years and 41% were older than 50 years. Seventeen patients (13%) were resistant to chemotherapy, and 18 (14%) died during induction treatment. Only age and performance status were significantly associated with response (P<.001 and .03, respectively). Death during consolidation occurred in four patients. The estimated 5-year overall survival (OS) was 22% for the entire group and 26% for patients younger than 35 years. Disease-free survival (DFS) at 5 years was 28% +/- 6 for patients younger than 35 years, 25% +/- 9 for patients between 35 and 50 years, and 0% for patients older than 50 years. Increasing age (P<.01) and expression of CD34 (P<.01) were adverse factors. Only three patients (3%) developed an isolated CNS relapse. CONCLUSION Intensive consolidation including high-dose cytarabine not followed by maintenance therapy provides an outcome for adult patients with ALL that may be worse or even inferior compared with studies using long-term maintenance therapy. High-dose cytarabine in combination with IT MTX was effective for CNS prophylaxis.

PURPOSE In our previous study with MACOPB, we identified a high-risk group of patients with a poor 3-year survival rate of 29%. These patients were defined as having at diagnosis advanced-stage disease with high tumor burden (TB) and elevated lactate dehydrogenase (LDH) level or bone marrow (BM) involvement. A novel therapeutic scheme was investigated to improve the outcome of these patients. PATIENTS AND METHODS Fifty patients with high-risk diffuse large-cell lymphoma (DLCL) were enrolled. The therapeutic scheme includes three phases: induction with 8 weeks of MACOPB; intensification with a 3-day course of mitoxantrone 8 mg/m2 plus high-dose cytarabine (HDARA-C) 2 g/m2 every 12 hours plus dexamethasone 4 mg/m2 every 12 hours (MAD protocol) and granulocyte colony-stimulating factor (G-CSF) 5 microg/kg on days 4 to 17 to harvest peripheral-blood progenitor cells (PBPC); consolidation with carmustine (BCNU), etoposide, ARA-C, and melphalan (BEAM) regimen; plus autologous stem-cell transplantation (ASCT) with PBPC, marrow, or both. RESULTS Thirty-six patients (72%) achieved a complete response (CR), 11 (22%) showed no response (NR), and three (6%) died of toxicity. Among the 22 PRs or NRs after the induction phase, 56% of patients achieved a CR with subsequent intensified therapy. With a median follow-up duration of 32 months, the overall survival and failure-free survival rates were 56% and 50%, respectively. The disease-free survival rate is 69% at 32 months. Leukapheresis after MAD and G-CSF yielded a median of 32 x 10(6)/kg CD34+ cells and 80 x 10(4)/kg granulocyte-macrophage colony-forming units (CFU-GM). Thirty-nine patients were autografted and 11 did not undergo ASCT: six because of disease progression, four due to toxicity, and one because of patient refusal. The median times to achieve engrafment were 11 days (range, 7 to 19) to a neutrophil count greater than 0.5 x 10(9)/L and 12 days (range, 8 to 60) to a platelet count greater than 50 x 10(9)/L. CONCLUSION This sequential scheme with intensified and high-dose chemotherapy with ASCT is feasible with moderate toxicity and may improve the outcome in high-risk DLCL.

PURPOSE One hundred thirty of 2,792 patients (5%) registered on three Intergroup Rhabdomyosarcoma Study clinical trials (IRS-I, -II, and -III) from 1972 to 1991 had an extraosseous Ewing's sarcoma (EOE). We report here the results of multimodality therapy for this tumor. PATIENTS AND METHODS The 130 patients were less than 21 years of age; 70 (54%) were males. Primary tumor sites were on the trunk in 41 patients, an extremity in 34, the head/neck in 23, the retroperitoneum/pelvis in 21, and other sites in 11. One hundred fourteen patients had no metastases at diagnosis. In 21 patients, the tumor was completely resected; in 30, the localized or regional tumor was grossly resected, and in 63 patients, grossly visible sarcoma was left behind. Sixteen patients (12%) had distant metastases at diagnosis. All patients were given multiagent chemotherapy and most received irradiation (XRT); none were treated with bone marrow transplantation. RESULTS One hundred seven patients (82%) achieved a complete response. At 10 years, 62%, 61%, and 77% of the patients were alive after treatment on IRS-I, IRS-II, or IRS-III therapeutic protocols, respectively, similar to figures obtained in all IRS patients. At last follow-up evaluation, 42 patients had died of progressive tumor and one of infection. Survival at 10 years was most likely for patients with tumor that arose in the head and neck, extremities, and trunk, and for those who underwent grossly complete tumor removal before initiation of chemotherapy. For patients with localized, gross residual tumor, adding doxorubicin (DOX) to the combination of vincristine, dactinomycin, cyclophosphamide (VAC), and XRT did not significantly improve survival in 39 patients (62% alive at 10 years) compared with that of 24 patients treated with VAC and XRT without DOX (65% alive at 10 years, P = .93). CONCLUSION This series indicated that EOE in children is similar to rhabdomyosarcoma (RMS) in its response to multimodal treatment. No benefit was apparent from the addition of DOX to VAC chemotherapy in patients with gross residual EOE.

PURPOSE A phase II study was performed to evaluate the antitumor activity and toxicity of irinotecan (CPT-11), a water-soluble derivative of camptothecin, in patients with prior chemotherapy-treated squamous cell cancer of the cervix. PATIENTS AND METHODS Forty-two patients were included in the study. The median age was 44 years (range, 24 to 59 years). The median Zubrod performance status was 1. All patients were refractory to first-line chemotherapy and 88% had received prior radiotherapy. The initial dose of CPT-11 was 125 mg/m2 given as a weekly 90-minute intravenous infusion for 4 weeks, every 6 weeks. Subsequent doses were unchanged, reduced, or omitted according to toxicity grade. RESULTS Forty-two patients were assessable for response. The overall response rate was 21%. The median time to response was 6 weeks and the median duration of response was 12 weeks. The overall median duration of survival was 6.4 months. A statistically significant survival advantage (median of 12.6 v 5.1 months) was found in patients whose disease responded to the treatment (P < .015). The major dose-limiting toxic effects (grade > or = 3) were nausea and vomiting (45%), diarrhea (24%), and granulocytopenia (36%). Grade > or = 3 anemia was encountered in 62% of patients and the incidence of thrombocytopenia was negligible. Less severe side effects were alopecia (48%), drug fever (43%), anorexia (33%), fatigue (33%), skin rash (21%), stomatitis (14%), and allergic reaction (9%). The gastrointestinal intolerance was dose-related. The incidence of bone marrow depression did not decrease with dose reduction, possibly because of a cumulative effect or hematologic intolerance by a subset of patients. CONCLUSIONS CPT-11 has significant activity in refractory cervical carcinoma. Gastrointestinal intolerance and hematologic toxicity must be monitored carefully. Further studies of alternative schedules may improve the tolerance and response rate.

PURPOSE To determine the feasibility and toxicity of inducing autologous graft-versus-host disease (GVHD) with cyclosporine in patients with multiple myeloma undergoing autologous stem-cell transplantation. PATIENTS AND METHODS Fourteen multiple myeloma patients with a median age of 50 years (range, 41 to 63) were enrolled. The median time from diagnosis to transplant was 651 days (range, 229 to 3,353). Ten patients had primary refractory disease, two were in first remission, and two were responsive to salvage therapy. The preparative regimen consisted of thiotepa, busulfan, and cyclophosphamide. Cyclosporine was administered daily for 28 days after the stem-cell infusion, and the dose was adjusted to maintain whole-blood cyclosporine levels between 50 and 150 ng/dL in the first seven patients (low-level group) and between 150 and 300 ng/dL in the other seven patients (high-level group). RESULTS All patients achieved neutrophil engraftment a median of 11 days after transplant. Four patients developed > or = grade 2 hepatic toxicity, six developed > or = grade 2 nephrotoxicity, and four developed reversible cardiac toxicity. Only one treatment-related death occurred. Cyclosporine was withheld in seven patients for a median of 6 days because of renal and/or liver dysfunction. One patient developed clinical skin GVHD, which responded to corticosteroid therapy. Six patients developed histologic evidence of GVHD without clinical signs of GVHD (subclinical GVHD). The incidence of clinical and subclinical GVHD was similar in both cyclosporine groups. Three of 11 patients assessable for response achieved remissions. Three patients experienced disease progression 80, 160, and 354 days after transplant. Ten patients are alive without progression between 56 and 444 days after transplant. CONCLUSION Induction of autologous GVHD by posttransplant cyclosporine is feasible and well tolerated in patients with multiple myeloma.
