PURPOSE To estimate the comparative cost-effectiveness of three regimens for metastatic non-small-cell lung cancer (NSCLC). METHODS Results from a randomized clinical trial of 612 European patients with NSCLC, and cost data from an academic cancer center, the Medical College of Virginia, were analyzed. In this post-hoc economic analysis, we compared vinorelbine alone, vinorelbine plus cisplatin, and a common regimen of vindesine plus cisplatin. RESULTS Vinorelbine plus cisplatin resulted in the longest mean survival time of the three regimens, 49.6 weeks, followed by vindesine plus cisplatin, 44.3 weeks, and vinorelbine, 41.6 weeks. Compared with vinorelbine alone, vinorelbine plus cisplatin added 56 days at a cost of $2,700, resulting in a cost-effectiveness ratio of $17,700 per year of life gained. Similarly, vindesine plus cisplatin added 19 days at a cost of $1,150, or $22,100 per year of life gained. Compared with vindesine plus cisplatin, vinorelbine plus cisplatin added 37 days at a cost of $1,570, or $15,500 per year of life gained. CONCLUSION The most effective regimen of vinorelbine plus cisplatin added substantial benefit compared with vinorelbine alone or another common treatment, vindesine plus cisplatin, at a cost-effectiveness within accepted limits for medical interventions. Vindesine plus cisplatin also added benefit at an acceptable cost per year of life gained. If vinorelbine is preferred because of its toxicity profile, the additional effectiveness of cisplatin added substantial benefit at an acceptable cost. Compared with other common medical interventions, chemotherapy for NSCLC has acceptable efficacy and cost-effectiveness and should not be arbitrarily denied based on clinical or economic grounds.

PURPOSE We used population pharmacokinetic-parameter estimates and designed a fixed dosing schedule to maintain plasma suramin concentrations between 100 and 300 micrograms/mL and then evaluated its performance. MATERIALS AND METHODS On day 1, patients received a 200-mg test dose and 1,000-mg/m2 loading dose. On days 2, 3, 4, and 5, patients received 1-hour infusions of 400, 300, 250, and 200 mg/m2, respectively. Subsequent 1-hour infusions of 275 mg/m2 were given on days 8, 11, 15, 19, 22, 29, 36, 43, 50, 57, 67, and 78. Therapy was discontinued for dose-limiting toxicity (DLT) or progressive disease (PD). Patients were to be removed from the fixed dosing schedule if, after day 5, three consecutive peak plasma suramin concentrations were greater than 300 micrograms/mL. RESULTS Forty-two patients, including 40 with hormone-refractory prostate cancer (HRPC), received 700 infusions. Forty patients were assessable for toxicity; 38 were assessable for response. Two patients with preexisting pulmonary disease died early of respiratory insufficiency. Treatment was discontinued in five patients due to DLT and in seven due to PD. No patient had treatment discontinued due to repeated peak plasma suramin concentrations > or = 300 micrograms/mL. The fixed dosing schedule was precise, unbiased, and well tolerated. DLT consisted of grade 4 nephrotoxicity (n = 2), neurotoxicity (n = 2), and corticosteroid-induced psychosis (n = 1). Three patients, who received all 18 doses of suramin per protocol, developed severe, but not dose-limiting, malaise, fatigue, and lethargy. Twenty-four of 36 assessable patients with elevated serum prostate-specific antigen (PSA) levels had a > or = 50% reduction, lasting more than 4 weeks, and 18 had a > or = 75% reduction, lasting more than 4 weeks. Twelve of 23 (52%) symptomatic HRPC patients noted a subjective improvement in pain. There were no measurable responses in four patients with measurable disease. The estimated median survival time in 38 assessable patients with HRPC was 18.8 months. The estimated median time to progression in 35 patients, for whom data were available, was 10.1 months. CONCLUSION This easily implemented schedule allowed suramin to be administered safely as an intermittent bolus injection. Toxicity was manageable and reversible.

PURPOSE The use of in vitro purging of bone marrow in autologous bone marrow transplantation (ABMT) for non-Hodgkin's lymphoma (NHL) has been a controversial issue; its benefit is as yet unproven. Its effect on the clinical outcome of ABMT in these patients is still unclear. We look at this issue using data from the European Blood and Marrow Transplant (EBMT) Lymphoma Registry. PATIENTS AND METHODS Seventeen hundred twenty-six patients with NHL have been reported to the EBMT registry, of whom 270 had bone marrow purged at transplant. Two hundred twenty-four of these patients were compared with a case-matched group of 224 unpurged patients who had undergone the same procedure. The case matching was made following selection of the main prognostic factors for progression-free survival (PFS) by multivariate analysis. Response, complications, and outcome in ABMT were analyzed. RESULTS Time to hematologic engraftment, response to ABMT, and number of procedure-related deaths were similar in purged and unpurged patients. The overall survival (OS) rate was 54% at 5 years in purged patients and 48.3% in unpurged patients (P = .1813). The PFS rate was 44.3% and 44.6%, respectively (P = .1961). Patterns of relapse, including bone marrow relapse, were similar in both groups. Patients with low-grade lymphoma did not have a significantly improved PFS if the bone marrow was purged (P = .1757); however, they did have a significantly improved OS (P = .00184). This increased OS was found to be associated with non-totalbody irradiation (TBI) conditioning and also with the purged patients undergoing transplantation at large transplant centers (P = .0016). CONCLUSION Purging of bone marrow in ABMT for NHL does not affect the rate of hematologic engraftment or risk of procedure-related death (PRD). There is no significant difference in PFS for patients whose bone marrow is purged as compared with unpurged.

PURPOSE To evaluate the predictive value of computed tomography (CT) scanning and single-photon emission computed tomography (SPECT) gallium (Ga) scanning in the disease-free survival of patients receiving high-dose chemotherapy and autologous stem-cell transplantation for non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS One hundred forty-three patients undergoing transplant for NHL underwent CT scanning of chest, abdomen, and pelvis, and a SPECT Ga scan before transplantation and at day + 100 after transplant. The failure-free survival (FFS) by scan result was analyzed. RESULTS In the diffuse aggressive lymphoma patients, the 1-year FFS for patients having a positive SPECT Ga scan at day + 100 was 15% compared with a 3-year FFS of 47% for those with a negative scan (P < .001). Patients with a positive CT scan at day + 100 had a 36% 3-year FFS, and those with a negative CT scan had a 39% 3-year FFS (P = not significant [NS]). An analysis of the combination of CT scan and SPECT Ga scan results at day + 100 posttransplant demonstrated a 3-year FFS of 14% if they were both abnormal; if the CT was positive and Ga was negative, the 3-year FFS was 68%; positive Ga with a negative CT was 25%; and both negative was 34% (P = .0015). For the patients with follicular NHL, those with a positive SPECT Ga at day + 100 had a 14% 1-year FFS compared with those with a negative scan, who had a 45% 3-year FFS (P < .001). In the follicular NHL patients, the 3-year FFS of those with a positive CT was 17% compared with a 64% 3-year FFS for patients with a negative CT scan (P < .001). CONCLUSION The use of SPECT Ga scan at day + 100 posttransplant for evaluation of disease activity in patients with diffuse aggressive NHL was highly predictive of eventual outcome and was more predictive than the CT scan results. However, for patients with follicular NHL, the addition of SPECT Ga scanning to CT scanning did not add substantially to the evaluation of transplant outcome.

PURPOSE To determine the treatment outcome of standard acute myeloid leukemia (AML)-type chemotherapy in a subset of patients with newly diagnosed myelodysplastic syndromes (MDS) compared with that of patients with de novo AML as defined using French-American-British (FAB) criteria. In addition, to determine the pretreatment variables having prognostic significance for treatment outcome in patients with MDS. PATIENTS AND METHODS Nine hundred seven newly diagnosed patients with no history of cytopenias having a local institutional de novo AML successfully karyotyped and treated on Cancer and Leukemia Group B (CALGB) protocols for AML from 1984 to 1992. Thirty-three of the 907 patients were reclassified as having MDS on central pathology review using FAB criteria and form the basis of this analysis. RESULTS The treatment outcomes for patients with MDS and AML were similar; the complete remission (CR) rate was 79% and 68%, respectively (P = .37); median CR duration was 11 and 15 months, respectively (P = .28); and median survival was 13 and 16 months, respectively (P = .72). For the MDS patients, there were no prognostic variables for CR rate identified. For CR duration, only the Sanz classification had prognostic value. The prognostic factors for survival in a univariate analysis included age, WBC count, Sanz classification, and percent blood blasts. In a proportional hazards analysis of survival, age greater than 60 years and WBC less than 2.6 x 10(9)/L were adverse prognostic factors. CONCLUSION In patients with no known history of cytopenias who are treated intensively at diagnosis, the FAB distinctions between MDS (refractory anemia with excess blasts and refractory anemia with excess blasts in transformation) and AML appear to have little therapeutic relevance.

PURPOSE Topotecan is a specific inhibitor of topoisomerase I. Preclinical data have indicated that topoisomerase I inhibitors demonstrate more efficacy and have a greater therapeutic index with prolonged continuous exposure. The feasibility of this concept in humans using a 21-day continuous infusion of topotecan has been reported. We conducted a phase II study of this 21-day continuous topotecan administration schedule in patients with locally advanced, unresectable or metastatic colorectal cancer. PATIENTS AND METHODS Topotecan, initially applied at a dose of 0.6 mg/m2/d, was administered as a continuous infusion via an ambulatory pump for 21 days repeated every 4 weeks. The starting dose was reduced to 0.5 mg/m2/d, because in five of the first 11 patients, the second course had to be delayed due to prolonged myelosuppression. Forty-two patients entered the study; one patient was ineligible and was excluded from further analyses. RESULTS The overall response rate was 10%, with one complete and three partial responses. The median response duration was 7 months (range, 4 to 11). With this schedule, the major toxicity was prolonged cumulative myelosuppression, including a marked inhibition of erythropoiesis. A total transfusion of 250 U of erythrocytes was needed to maintain a hemoglobin level greater than 6.0 mmol/L. Other side effects were mild, and included alopecia (47%), periodic nausea (40%)/vomiting (22%), and fatigue (16%). Pharmacokinetic evaluation showed a mean steady-state plasma concentration (Css) of topotecan of 0.62 ng/mL (range, 0.33 to 1.1), with a significant relationship between the Css of topotecan and common cytotoxicity criteria (CTC) grade of leukocytopenia. CONCLUSION Topotecan administered as a 21-day continuous infusion exerts minor activity as single-agent therapy in patients with metastatic colorectal cancer.

PURPOSE Influences of adjuvant epirubicin/cyclophosphamide (EC) chemotherapy on blood coagulation were investigated in patients with operable breast cancer and the incidence of thromboembolic events was recorded. PATIENTS AND METHODS In 50 consecutive node-positive breast cancer patients, serial coagulation studies (fibrinogen method of Clauss, antithrombin III, protein C amidolytic methods, D dimer enzyme-linked immunoadsorbent assay [ELISA] techniques, and plasminogen activator inhibitor [PAI] activity u-PA inhibition test) and impedance plethysmography (IPG) for screening of deep vein thrombosis (DVT) were performed preoperatively and postoperatively, before each of six cycles of adjuvant chemotherapy (60 mg/m2 epirubicin and 600 mg/m2 cyclophosphamide) and 3 months thereafter. Seventy-two healthy women served as controls. RESULTS During chemotherapy, the phlebographically proven DVT incidence was 10% (n = 2 after second cycle; n = 3 after third cycle). Preoperative levels of D-dimer, fibrinogen, and the PAI activity were significantly higher than in healthy women and only mean levels of the D-dimer were significantly higher in patients with DVT compared with patients without DVT. Postoperatively, only D-dimer and fibrinogen levels significantly increased, while in the course of chemotherapy, these levels were significantly decreased. Mean D-dimer levels and PAI increased steadily in patients with DVT. Preoperatively and during chemotherapy, levels of antithrombin III and protein C were within the normal range. Only one patient with DVT had decreased protein C levels throughout chemotherapy. CONCLUSION Monitoring with sophisticated coagulation tests during adjuvant EC chemotherapy for breast cancer does not identify patients at higher risk for DVT development. Preoperatively, in patients with later DVT, an imbalance of hemostasis is already present; thus, thrombosis might predominantly be initiated by malignancy-induced hypercoagulability and secondarily by the influence of EC chemotherapy. Prospective randomized trials must determine whether prophylactic anticoagulation during EC chemotherapy reduces the incidence of DVT.

2 Background: Incidence of advanced NSCLC in the elderly is increasing. Specific trials for elderly are seldom and those patients are not optimally treated. Current recommendations are monotherapies with gemcitabine or vinorelbine. Methods: French multicentric randomized phase III study in pts aged 70 to 89, PS 0-2 with advanced NSCLC not irradiable, comparing a 3-weekly single agent therapy (gemcitabine 1,150 mg/m2 or vinorelbine 30 mg/m2, d1, d8: arm A) with carboplatin AUC 6 every 4 weeks + paclitaxel 90 mg/m2 (d1,8,15) doublet (arm B). Five cycles of single agent and 4 cycles of the doublet were to be given. Second-line in case of toxicity or progressive disease was fixed with erlotinib 150 mg/d. The main endpoint was overall survival. Results: 451 pts were included from 04/2005 to 12/2009 by 60 centers. Males were 73.8%, median age was 77.2 years (range 70-89). PS was 0-1 in 73.6%. The 2 arms were well-balanced for pts characteristics. At time of second planned intermediate analysis (after two-third of expected deaths, i.e. 224), 451 pts were randomized, out of the 522 initially planned. The steering committee advice was to stop the inclusions. Overall survival of the 313 pts analysed at this time was significantly longer in arm B (median: 10.4 months, 95%CI: [8.2; 15.0] vs. 6.2 months, 95%CI: [5.3; 7.5] for arm A, (HR = 0.60, 95%CI : [0.46; 0.78], p = 0.0001). Median PFS was 6.3 months, 95%CI: [5.5; 6.9] in arm B vs. 3.2 months, 95%CI: [0.44; 0.70] (HR = 0.55, 95%CI: [0.44; 0.70], p < 0.0001). Grade 3-4 haematological toxicities were significantly more frequent in arm B (17.9% vs. 54.1%). No significant difference was observed in early deaths (arm A: 23.7%, arm B: 16.6%). Survival, response and toxicity data for the whole series of 451 pts will be updated at time of the meeting. Conclusions: Paclitaxel and carboplatin doublet provides a significantly longer survival in elderly pts with advanced NSCLC than current standard single agent therapy, with acceptable toxicity, making it a new treatment paradigm for PS 0-2 pts ≥ 70 years.

4 Background: Ipilimumab, a fully human monoclonal antibody against cytotoxic T-lymphocyte antigen-4, demonstrated activity in advanced melanoma. Gp100 vaccine showed immunological and clinical responses, and enhanced clinical activity when combined with other immunotherapy. This phase III study compared efficacy and safety of ipilimumab or gp100 monotherapy and combination. Methods: Eligible patients (HLA-A*0201+ previously treated adults with unresectable stage III/IV melanoma) were randomized 1:3:1 to ipilimumab (3 mg/kg q3w x 4 doses) + placebo (n=137), ipilimumab + gp100 (peptides 209-217[210M] and 280-288 [288V]; 1mg q3w x 4 doses; n=403), or gp100 + placebo (n=136). There was no maintenance phase. Primary endpoint was comparison of overall survival (OS) between patients who received combination versus gp100 alone; secondary endpoints were all other OS comparisons, best overall response rate (BORR), disease control rate (DCR) to W24, progression-free survival (PFS), and safety. Results: The study demonstrated statistically significant results for all efficacy endpoints (below). Ipilimumab alone or combined with gp100 resulted in a significant improvement in OS with risk reduction of 32-34% compared to gp100. Significant differences in DCR, BORR, and PFS were observed. Adverse events with ipilimumab were consistent with prior studies: generally mild, immune-related, and medically manageable. Conclusions: Ipilimumab is the first agent to improve median and long-term OS in a phase III study of previously treated patients with advanced melanoma. Addition of gp100 vaccine to ipilimumab did not improve outcome. [Table: see text] [Table: see text]

LBA4007 Background: The median survival for patients (pts) with AGC in most phase III studies is less than 1 year. The addition of bevacizumab (bev) to chemotherapy (chemo) is supported by a strong preclinical rationale and by phase II evaluation. AVAGAST is the first randomized study to compare the efficacy and safety of bev + chemo vs placebo + chemo. Methods: Pts with inoperable, locally advanced or metastatic stomach/gastroesophageal junction adenocarcinoma with no prior therapy were randomized 1:1 to capecitabine (cape, or 5-FU) + cisplatin (cis) and either bev (7.5 mg/kg iv) or placebo q3w. Stratification variables: geographical region, fluoropyrimidine treatment, disease status. Cis was given for 6 cycles; bev/placebo + cape/5-FU were given until disease progression or unmanageable toxicity. Primary objective: compare overall survival (OS); secondary objectives: compare progression-free survival (PFS), overall response rate (ORR), and safety (as overseen by an independent DSMB). Results: From Sep 2007 to Dec 2008, 774 pts were enrolled. Treatment arms were balanced. Approx 95% of pts were metastatic. Two-thirds of pts were male, 49% of pts were from Asia/Pacific, 32% from Europe and 19% from the Americas. Median OS was 10.1 months with chemo + placebo and 12.1 months with chemo + bev in the intent-to-treat population (HR 0.87; p=0.1002). Median OS according to geographical region was 6.8 vs. 11.5 months (HR 0.63) in the Americas, 8.6 vs. 11.1 months (HR 0.85) in Europe and 12.1 vs. 13.9 months in Asia-Pacific (HR 0.97). Secondary endpoints and AEs of special interest for Bev are summarized below ( Table ). Conclusions: While the primary endpoint was not met (median OS HR 0.87; p=0.1002), there was a significant improvement in PFS and ORR and an acceptable safety profile for bev + chemo in patients with AGC.
