PURPOSE This analysis was performed to determine the most appropriate volume that should be encompassed by thoracic radiation treatments (TRTs) for patients with limited-stage small-cell lung cancer (LSSCLC) who have responded to initial chemotherapy. PATIENTS AND METHODS A retrospective review of all patients (N = 67) with LSSCLC who were not entered onto a research protocol and were treated at our institution between the years of 1982 and 1990 was performed. Fifty-nine of 67 patients had adequate information regarding the size of the tumor before the start of chemotherapy (computed tomographic [CT] scan of chest or chest x-ray), the size of the tumor before TRT, and the TRT field size based on a simulation radiography. All 59 patients were treated with cyclophosphamide-based chemotherapy, and TRT was generally delivered concomitantly with chemotherapy following two to three cycles of chemotherapy alone. RESULTS Of 59 patients, 28 were treated with TRT field sizes that encompassed postchemotherapy tumor volumes, and 31 patients were treated with TRT field sizes that encompassed prechemotherapy tumor volumes (defined as a volume that included at least a 1.5-cm margin on the prechemotherapy tumor volume). Nineteen patients had an intrathoracic recurrence of disease as the first site of recurrent small-cell carcinoma: 10 of 31 patients treated with TRT fields that encompassed prechemotherapy tumor volumes and nine of 28 patients treated with TRT fields that encompassed postchemotherapy tumor volumes. For the 28 patients treated with TRT fields that encompassed postchemotherapy tumor volumes, the greatest distance that the prechemotherapy tumor volume (without margins) extended beyond the edge of the TRT field was 0.5 to 5.0 cm, with a median of 2.5 cm. All 19 of the intrathoracic recurrences were in-field failures, although two patients (one prechemotherapy volume and one postchemotherapy volume) did have concurrent pleural effusions. CONCLUSION These results indicate that the use of TRT fields that encompass postchemotherapy tumor volumes does not increase the risk of marginal failures or intrathoracic failures outside the TRT field.

PURPOSE To assess the toxicity, efficacy, and applicability of high-dose therapy with bone marrow and/or peripheral-blood autotransplantation in high-risk, previously untreated patients with multiple myeloma. PATIENTS AND METHODS Thirteen consecutive patients with high-labeling index (LI) multiple myeloma received a novel high-dose sequential (HDS) regimen consisting in the high-dose administration of cyclophosphamide (7 g/m2) followed by vincristine (1.4 mg/m2) plus methotrexate (8 g/m2 with leucovorin rescue), etoposide (2 g/m2) and, finally, total-body irradiation (TBI; 10 Gy) plus melphalan (120 mg/m2) with autografting of peripheral-blood hematopoietic progenitor cells. Recombinant human granulocyte-macrophage colony-stimulating factor (rhGM-CSF; 5 micrograms/kg/d) was continuously infused after cyclophosphamide and etoposide both to accelerate hematopoietic recovery and to expand/mobilize the hematopoietic progenitor-cell pool. RESULTS Among 13 patients, 12 completed the program; 10 (or 77%) achieved a complete response and five are alive and disease-free after a median follow-up duration of 36 months (range, 24 to 52). The durations of both freedom from progression (FFP; median, 38 months) and overall survival (OS; median, 41 months) were significantly superior in the 13 HDS-treated patients as compared with 19 well-matched historical controls. CONCLUSION HDS emerges as a highly effective, well-tolerated, and widely accessible regimen capable of imparting a survival benefit to patients with high-LI multiple myeloma. Larger studies using this or similar programs in standard-risk myeloma are clearly warranted.

PURPOSE We conducted a dose-escalation study of 2-chlorodeoxyadenosine (2-CdA) added to a standard fixed dose of chlorambucil to evaluate the toxicity of the combined regimen in patients with chronic lymphocytic leukemia (CLL) and low-grade lymphoma. PATIENTS AND METHODS A total of 15 adults with relapsed or refractory CLL or low-grade lymphoma were to receive chlorambucil orally (30 mg/m2) every 2 weeks. Also, groups of three patients were to receive escalating doses of continuous intravenously administered 2-CdA at 1, 2, or 4 mg/m2/d for 7 days repeated at monthly intervals. All patients had pharmacokinetic studies during the first cycle of 2-CdA therapy; the results were compared with other institutional phase I studies in which comparable amounts of 2-CdA were administered by bolus infusion for 5 days. RESULTS The maximal-tolerated dose of 2-CdA that could be combined with chlorambucil was 2 mg/m2/d for 7 days for a maximum of two courses. At a higher dose level of 2-CdA or at the maximal-tolerated dose level given for more than two courses, severe and protracted pancytopenia, sometimes associated with life-threatening infections, was noted. Nonhematologic toxicities were limited to moderate degrees of nausea, vomiting, anorexia, and fatigue. Results of the pharmacologic studies suggested that 2-CdA clearance was independent of administration schedule and was unaffected by concomitant administration of chlorambucil. CONCLUSION These observations suggest the possibility of combining two cycles of continuous intravenously administered 2-CdA (2 mg/m2/d for 7 days) with standard doses of oral chlorambucil to test the efficacy of the combination regimen in phase II trials.

PURPOSE Fludarabine is an active agent for patients with low-grade lymphoma (LGL) but has mainly been used as a single agent. This trial was designed to define the maximum-tolerated dose (MTD) of a combination of fludarabine, mitoxantrone, and dexamethasone (FND), to identify the toxicities of these agents in combination, and to make preliminary observations about the efficacy of this combination. PATIENTS AND METHODS Twenty-one patients with recurrent LGL or follicular large-cell lymphoma were treated, in cohorts of three, at stepwise escalating doses. Patients were required to have adequate marrow function and normal renal, hepatic, and cardiac function. RESULTS The MTD of the combination was found to be as follows: fludarabine, 25 mg/m2/d (days 1 to 3); mitoxantrone, 10 mg/m2 (day 1); and dexamethasone, 20 mg/d (days 1 to 5). Each course was administered monthly, and up to eight courses were given. Dose-limiting toxicities were neutropenia and infections. Thrombocytopenia was modest. Nonhematologic toxicity was very modest. Responses were seen at every dose level. The overall response rate was 71%, with a 43% complete remission (CR) rate. The median duration of CR was 18 months (with follow-up duration from 13 to 28+ months). CONCLUSION FND was well tolerated in this population. While our primary aim was to define the MTD, our preliminary observations on the efficacy of the regimen were favorable. The overall response rate was high, there was a high fraction of CRs, and our early impression is that these responses are durable.

PURPOSE To evaluate the clinical value of growth factors (GFs) with peripheral-blood stem cells (PBSC) collected following mobilization with GFs, we randomized patients to receive or not to receive GFs following transplant. PATIENTS AND METHODS Thirty-seven patients were apheresed after receiving the combination of granulocyte colony-stimulating factor (G-CSF) with granulocyte-macrophage colony-stimulating factor (GM-CSF) at doses of 10 micrograms/kg/d and 5 micrograms/kg/d, respectively, for 6 days before apheresis and during a median of 4 days of collections. One day after the infusion of autologous marrow and PBSC, patients were randomly assigned to receive no GFs or a combination of G-CSF (7.5 micrograms/kg/d) and GM-CSF (2.5 micrograms/kg/d), both as a 2-hour intravenous (i.v.) infusion twice per day until the neutrophil count was greater than 1,500/microL. RESULTS The median days to recovery to an absolute neutrophil count (ANC) of 100/microL (9 v 11.5, P = .0005), 500/microL (10 v 16, P = .0004), or 1,000/microL (12 v 21, P = .0008) was shortened with the use of GFs, post-PBSC infusion. In addition, the duration of hospitalization was shorter (19 v 21 days, P = .0112) in the arm receiving GFs post-PBSC infusion. There was no significant difference between the two study arms in the duration of fever, documented septic episodes, or RBC or platelet transfusion requirements. CONCLUSION Despite faster neutrophil recovery and shortened duration of hospitalization with GFs administered after PBSC transplantation, the measured clinical variables of febrile days, septic episodes, and transfusion requirements were similar between the study arms. The use of GFs post-PBSC transfusion is associated with a modest clinical benefit.

PURPOSE This phase II study was designed to assess the effects of mitoxantrone with prednisone in patients with metastatic prostate cancer who had progressed on hormonal therapy. The methods of assessment included quality-of-life analyses, pain indices, analgesic scores, and the National Prostatic Cancer Project (NPCP) criteria. PATIENTS AND METHODS Patients received mitoxantrone 12 mg/m2 intravenously every 3 weeks plus prednisone 10 mg orally daily. All had a castrate serum testosterone and Eastern Cooperation Oncology Group (ECOG) performance status < or = 3, and had not received prior chemotherapy. Every 3 weeks, analgesic intake was scored, and a present pain intensity (PPI) record and visual analog scale (VAS) describing pain were collected. Every 6 weeks, the European Organization for Research and Treatment of Cancer (EORTC) core quality-of-life questionnaire plus a prostate-specific module were completed. A palliative response was defined as a decrease in analgesic score by > or = 50% or a decrease in PPI by > or = two integers without any increase in the other. RESULTS Twenty-seven patients were entered onto the study. Nine of 25 (36%) assessable patients achieved a palliative response maintained for > or = two cycles (range, two to eight or more). Improvements in mean PPI and VAS pain scores after each cycle of therapy (P < .05) were seen. Quality-of-life analysis showed improvements in social and emotional functioning, and in pain and anorexia. Using NPCP criteria, one patient achieved a partial response (PR) and 12 had stable disease; one of seven patients with measurable disease had a PR. No serious nonhematologic toxicity was experienced, and there were no episodes of febrile neutropenia. CONCLUSION Mitoxantrone with low-dose prednisone is a well-tolerated treatment regimen that has some beneficial effects on disease-related symptoms and quality of life for patients with advanced prostate cancer.

PURPOSE To evaluate the clinical safety and ability of PIXY321, a novel fusion protein of recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3), to ameliorate chemotherapy-induced multilineage myelosuppression. PATIENTS AND METHODS PIXY321 was administered by subcutaneous injection twice daily (25 to 1,000 micrograms/m2/d) over 14 days to 24 chemotherapy-naive patients with sarcoma in a phase I/II study. Three weeks from the initiation of PIXY321, the first cycle of chemotherapy with cyclophosphamide, doxorubicin, and dacarbazine (DTIC) (CyADIC) was administered over 3 days. Four weeks later, a second cycle of CyADIC was administered, followed by 14 days of PIXY321. RESULTS Treatment with PIXY321 was well tolerated. Local skin reactions and constitutional symptoms were the main side effects. The dose-limiting toxicity was not encountered; however, headache and fatigue were more frequent at the highest dose (1,000 micrograms/m2). PIXY321 before chemotherapy elicited a modest increase in the WBC count (consisting mainly of mature neutrophils), platelets, and corrected reticulocyte counts (all P < .001). Following chemotherapy, PIXY321 at effective doses (500 to 1,000 micrograms/m2/d), significantly reduced both the degree (mean nadir, 70 v 310/microL; P = .016) and duration (mean days < 500/microL, 6.6 v 3.9 days; P = .002) of neutropenia. Cumulative thrombocytopenia was not observed during the first two cycles of CyADIC (mean nadir platelet count, 103 v 95 x 10(3)/microL, in cycles no. 1 and 2, respectively; P = NS). Compared with our historic control data, the mean nadir platelet count in cycle no. 2 was significantly higher after PIXY321 (1.7-fold, P < .05) than with CyADIC alone or with GM-CSF support. There was a suggestion for a dose response, since the mean percentage change in nadir platelet values from cycle no. 1 to cycle no. 2 increased with the PIXY321 dose (P < .02), with the peak effect observed at 750 micrograms/m2/d. CONCLUSION These results suggest a potential clinical role for PIXY321 in attenuating the cumulative multilineage hematopoietic toxicity of chemotherapy.

PURPOSE The United Kingdom Central Lymphoma Group (CLG) has modified mechlorethamine, vincristine, procarbazine, and prednisone/doxorubicin, bleomycin, vinblastine, and dacarbazine (MOPP/ABVD) by substituting mechlorethamine with chlorambucil and dacarbazine with etoposide in the treatment of patients with advanced Hodgkin's disease (HD). Prednisolone is included in the bleomycin-containing combination, and the vinca alkaloids have been switched to balance the myelotoxicity of the two component regimens. PATIENTS AND METHODS The resulting ChlVPP/PABlOE regimen is as follows: on days 1 to 14, chlorambucil 6 mg/m2 orally, procarbazine 100 mg/m2 orally, and prednisolone 30 mg/m2 orally; on days 1 and 8, vinblastine 6 mg/m2 intravenously (i.v.); on day 29, doxorubicin 40 mg/m2 i.v.; on days 29 and 36, vincristine 1.4 mg/m2 (maximum, 2 mg) i.v., and bleomycin 10 mg/m2 i.v.; on days 30, 31, and 32, etoposide 200 mg/m2/d orally; on days 29 to 43, inclusive, prednisolone, 30 mg/m2 orally. The second full cycle restarts on day 50. Treatment continues to maximum response plus two full cycles, but with a minimum of three full cycles. Radiotherapy is administered, after chemotherapy, to sites of previously bulky disease. Since 1983, 216 patients with previously untreated, advanced Hodgkin's disease (HD) have entered this study. RESULTS The complete remission (CR) rate after chemotherapy was 73% (95% confidence interval [CI], 67% to 79%), and after additional radiotherapy was 85% (95% CI, 80% to 90%). The failure-free survival (FFS) rate at 5 years was 68% (95% CI, 61% to 74%), and the overall actuarial survival at 5 years was 78% (95% CI, 72% to 84%). The CR rate in patients in the poorer prognostic categories was high: 81% in patients with albumin levels less than 37 g/L, 79% in patients older than 40 years of age, 84% in stages IIIB plus i.v. disease, and 79% in patients presenting with B symptoms. As expected, nausea and vomiting were not major problems, although infection, often in the context of myelosuppression, complicated almost half the cases, and 29% of patients required admission at some stage for treatment of infection. CONCLUSION In this multicenter study, ChlVPP/PABlOE produced results comparable to those reported for MOPP/ABVD, but with less nausea and vomiting. Treatment duration was shorter than in the original MOPP/ABVD regimen, and than that used in the Cancer and Leukemia Group B (CALGB) trial. It will now be compared with PABlOE alone.

PURPOSE Some phase II studies have suggested that the combination of interferons (IFNs) with dacarbazine (DTIC) in the treatment of malignant melanoma (MM) increases the antitumor activity of DTIC alone. In an attempt to confirm this hypothesis, a randomized study was performed with the further intent of observing whether low doses of recombinant interferon alfa-2a (rIFN alpha 2a) could be as effective as intermediate doses. PATIENTS AND METHODS Two hundred sixty-six patients were randomized onto three different treatment arms: DTIC 800 mg/m2 intravenously (IV) days 1 and 21; DTIC plus rIFN alpha 2a 9 mIU intramuscularly (IM) daily; and DTIC plus rIFN alpha 2a 3 mIU IM three times per week. Major prognostic factors were well balanced among the three arms. Chemotherapy was administered for a maximum of eight cycles. After 6 months of therapy, rIFN alpha 2a was continued until disease progression at 3 mIU three times per week in responding patients who had received the combined treatment. RESULTS The percentage of objective responses did not differ among the three groups (20%, 28%, and 23%, respectively), although a significant prolongation of response duration was observed when rIFN alpha 2a was added to DTIC (2.6 v 8.4 v 5.5 months, respectively). However, this improvement in response duration did not translate into an amelioration of overall survival. The addition of rIFN alpha 2a led to the onset of flu-like syndrome, but in no case was it necessary to withdraw the treatment program and no toxic deaths or life-threatening toxicities were reported. CONCLUSION In this study, rIFN alpha 2a significantly prolonged response duration, whereas no effects on response rate and survival were observed; rIFN alpha 2a 3 mIU appeared to be equally effective and better tolerated than 9 mIU.

PURPOSE To study the effects of cyclosporine (CsA), a modulator of multidrug resistance (MDR), on the pharmacokinetics and toxicities of doxorubicin. PATIENTS AND METHODS Nineteen patients with incurable malignancies entered this phase I trial. Initially patients received doxorubicin alone (60 or 75 mg/m2) as a 48-hour continuous intravenous (i.v.) infusion. Patients whose tumors did not respond received CsA as a 2-hour loading dose of 6 mg/kg and a 48-hour continuous infusion of 18 mg/kg/d with doxorubicin. Target CsA levels were 3,000 to 4,800 ng/mL (2.5 to 4.0 mumol/L). Doxorubicin doses were reduced to 40% of the prior dose without CsA, and then escalated until myelosuppression equivalent to that resulting from doxorubicin alone was observed. Doxorubicin pharmacokinetics were analyzed with and without CsA. RESULTS Thirteen patients received both doxorubicin alone and the combination of doxorubicin and CsA. Mean CsA levels were more than 2,000 ng/mL for all cycles and more than 3,000 ng/mL for 68% of cycles. Dose escalation of doxorubicin with CsA was stopped at 60% of the doxorubicin alone dose, as four of five patients at this dose level had WBC nadirs equivalent to those seen with doxorubicin alone. Nonhematologic toxicities were mild. Reversible hyperbilirubinemia occurred in 68% of doxorubicin/CsA courses. The addition of CsA to doxorubicin increased grade 1 and 2 nausea (87% v 47%) and vomiting (50% v 10%) compared with doxorubicin alone. There was no significant nephrotoxicity. Paired pharmacokinetics were studied in 12 patients. The addition of CsA increased the dose-adjusted area under the curve (AUC) of doxorubicin by 55%, and of its metabolite doxorubicinol by 350%. CONCLUSION CsA inhibits the clearance of both doxorubicin and doxorubicinol. Equivalent myelosuppression was observed when the dose of doxorubicin with CsA was 60% of the dose of doxorubicin without CsA. Understanding these pharmacokinetic interactions is essential for the design and interpretation of clinical trials of MDR modulation, and should be studied with more potent MDR modulators.

PURPOSE This dose-ranging trial of intravenous dolasetron mesylate (MDL73,147EF) was performed to determine its adverse and antiemetic effects in patients receiving cisplatin at doses > or = 100 mg/m2. PATIENTS AND METHODS Eighty-nine patients treated with initial cisplatin received a single intravenous dose of dolasetron mesylate administered over 20 minutes beginning 30 minutes before chemotherapy. The following four dose levels were studied: 1.8, 2.4, 3.0, and 5.0 mg/kg. Emesis and adverse effects were measured for 24 hours after cisplatin. RESULTS All adverse effects were mild and transient including loose stools, headache, serum AST/ALT elevations, and asymptomatic prolongation of ECG intervals. Among the dose levels, no-emesis rates from 24% to 52% were observed, and the percentage of patients having zero, one, or two emetic episodes ranged from 48% to 82%. Complete control of vomiting increased as the dose was escalated to 2.4 mg/kg, but did not improve further with higher doses. CONCLUSION Dolasetron mesylate can be administered safely at doses up to 5.0 mg/kg, with comparable complete protection rates and increased adverse effects at doses greater than 2.4 mg/kg. Antiemetic activity was seen after cisplatin. Trials comparing single infusions of dolasetron mesylate and ondansetron are under way.
