ABSTRACT

PURPOSE: In our previous phase II study, the cisplatin, gemcitabine, and vinorelbine (PGV) regimen produced a median survival time (MST) of approximately 1 year in advanced non-small-cell lung cancer (NSCLC) patients. The present study was aimed at comparing the MST of patients treated with this triplet regimen with the MSTs of patients receiving cisplatin and vinorelbine (PV) or cisplatin and gemcitabine (PG). PATIENTS AND METHODS: From April 1997, patients with locally advanced or metastatic NSCLC, an age of < or = 70 years, and an Eastern Cooperative Oncology Group performance status < or = 1 were randomized to receive one of the following regimens: cisplatin 50 mg/m(2), gemcitabine 1,000 mg/m(2), and vinorelbine 25 mg/m(2) on days 1 and 8 every 3 weeks (arm A); cisplatin 100 mg/m(2) on day 1 and gemcitabine 1,000 mg/m(2) on days 1, 8, and 15 every 4 weeks (arm B); or cisplatin 120 mg/m(2) on days 1 and 29 and vinorelbine 30 mg/m(2)/wk (arm C). According to the two-stage design for phase III trials, an interim analysis was planned when the first 60 patients per arm were assessable for survival. RESULTS: The survival data of 180 NSCLC patients (stage IIIB, 76 patients; stage IV, 104 patients) were analyzed in April 1999. Overall, 128 patients had died (PGV, n = 33; PG, n = 42; and PV, n = 53). The MST of patients in the PGV, PG, and PV arms was 51, 42, and 35 weeks, respectively, and the corresponding 1-year projected survival rates were 45%, 40%, and 34%, respectively. When only patients with stage IV disease were considered, an even stronger difference was seen between PGV (MST = 47 weeks) and both PG (34 weeks) and PV (27 weeks). At multivariate Cox analysis, the estimate hazard of death for patients receiving PGV compared with those receiving PV was 0.35 (95% confidence interval, 0.16 to 0.77; P <.01). The response rates were 47% in the PGV arm, 30% in the PG arm, 25% in the PV arm. Both hematologic and nonhematologic toxicities were not substantially worse in patients who received the PGV regimen. CONCLUSION: The PGV regimen is associated with a substantial survival gain (MST > 3 months longer) when compared with the PV combination. Because this difference in survival met one of the early stopping rules, the accrual in the PV arm has been stopped (null hypothesis rejected). Enrollment still continues in the PGV and PG arm to ascertain whether the PGV regimen can also produce a significantly longer survival than that obtained with the PG regimen.

ABSTRACT

In a previous phase II randomized study, a cisplatin/gemcitabine/vinorelbine (PGV) regimen produced a 50-week median survival time (MST) in advanced non small-cell lung cancer (NSCLC) patients. The present trial was planned to randomly compare the outcome of patients treated with this new triplet regimen with those of patients receiving either cisplatin plus vinorelbine (PV) or cisplatin plus gemcitabine (PG) doublet combinations. One hundred eighty patients with stage IIIB (76) or IV (104) disease, aged

ABSTRACT

The results of a prospective trial of an 8 week treatment for elderly patients with advanced intermediate-high grade NHL are reported. Our aim was to reduce general toxicity without losing an antilymphoma effect. For this reason the use of growth factor was studied. We also analysed the behavior of different histological groups (E + F vs G + H). From November 1991 to November 1993 100 patients older than 65 years with combination intermediate-high grade advanced stage NHL were treated with the P-VEBEC regimen, an original including epirubicin 50 mg/sqm, cyclophosphamide 300 mg/sqm and etoposide 100 mg/sqm on weeks 1, 3, 5, 7; vinblastine 5 mg/sqm and bleomycin 5 mg/sqm on weeks 2, 4, 6, 8; prednisone 50 mg/sqm/day per os in the first two weeks and thereafter every other day .46 pts received rG-CSF 5 micrograms/Kg/day throughout the treatment starting on day 2 of every week for 4 consecutive days. Twenty eight pts had B symptoms, 41 had bulky disease, 37 LDH levels above normal, 50 stage IV patients and 30 had bone marrow involvement. Sixty two percent achieved a complete remission (CR). Adverse prognostic factors for CR were E and F histology, stage IV disease, bone marrow infiltration, serum LDH levels above normal, international Prognostic Index (I.I.) intermediate-high and high risk categories and relative dose intensity (RDI) less than 0.80. Severe toxicity was rarely recorded and only one toxic death was observed. With a median follow-up of 33 months OS, DFS and EFS were 44%, 60% and 30% respectively. EFS was influenced by stage, BM involvement, level of LDH and I.I. intermediate-high and high risks. The 52 patients with DLCL (diffuse large cell lymphomas--G + H according to WF) did better with a higher CR, OS, DFS and EFS rates, than the other WF subtypes. In conclusion P-VEBEC is a feasible combination to use in elderly patients, mainly in DLCL. The use of rG-CSF improves the RDI. A RDI > 0.80 could play a role in improving the outcome, especially in patients with adverse prognostic factors. For other subgroups another schedule is probably justified.
