Gemcitabine with either paclitaxel or vinorelbine vs paclitaxel or gemcitabine alone for elderly or unfit advanced non-small-cell lung cancer patients.

The aim of this study was to assess whether a combination of gemcitabine (GEM) with either paclitaxel (PTX) or vinorelbine (VNR) could be more effective than GEM or PTX alone in elderly or unfit advanced non-small-cell lung cancer (NSCLC) patients. A total of 264 NSCLC patients aged >70 years with ECOG performance status (PS)< or =2, or younger with PS=2, were randomly treated with: GEM 1200 mg m(-2) on days 1, 8 and 15 every 28 days; PTX 100 mg m(-2) on days 1, 8 and 15 every 28 days; GEM 1000 mg m(-2) plus PTX 80 mg m(-2) (GT) on days 1 and 8 every 21 days; GEM 1000 mg m(-2) plus VNR 25 mg m(-2) (GV) on days 1 and 8 every 21 days. In all arms, an intra-patients dose escalation was applied over the first three courses, provided that no toxicity of WHO grade > or =2 had previously occurred. At present time, 217 (82%) patients had died. The median (months) and 1-year survival probability were 5.1 and 29% for GEM, 6.4 and 25% for PTX, 9.2 and 44% for GT, and 9.7 and 32% for GV. Multivariate analysis showed that PS< or =1 (hazard ratio (HR)=0.67; 95% CI 0.51-0.90), and doublet treatments (HR=0.76; 95% CI 0.59-0.99) were significantly associated with longer survival. Doublets produced no more toxicity than single agents. GT should be considered a reference regimen for elderly NSCLC patients with PS< or =1.

Lymphocyte subset pattern in acromegaly.

Immune function in acromegalic patients has been poorly investigated. The aim of this study was to evaluate the main surface antigen clusters of circulating lymphocytes in acromegaly. One hundred patients with active acromegaly (55 women and 45 men, aged 20-70 yr) and 200 healthy subjects sex- and age-matched with the patients (110 women and 90 men, aged 20-70 yr) were enrolled in this study. All patients and controls were born and live in Southern Italy. No patient had received octreotide, bromocriptine or corticosteroids for at least 3 months before entering the study. The analysis of lymphocyte subset pattern was performed by flow cytometry and fluorescein isothiocyanate or phycoerythrin directly conjugated monoclonal antibodies specific for the cell surface antigen clusters (CD) representing T-cell population as a whole (CD3), T helpers (CD4), T suppressors (CD8), natural killer cells (CD16) and B-cell population as a whole (CD19). Acromegalics had significantly increased levels of CD3 (67.1+/-7.2 vs 64.3+/-8.8%; p=0.03) and CD4 (37.8+/-3.5 vs 36.4+/-4.3%; p=0.004) and decreased levels of CD8 (31.4+/-3.3 vs 33.7+/-8.2%; p<0.01) and CD19 (12.1+/-3.1 vs 15.2+/-5.1; p=0.01) without age-difference. The results of the current study demonstrate an increase in T-cell activity together with a decrease in B-cell activity in a very large series of patients with active acromegaly. These data further support the existence of abnormalities of the immune system in patients with chronic GH/IGF-1 excess.

Phase I/II study of paclitaxel, gemcitabine and vinorelbine as first-line chemotherapy of non-small-cell lung cancer.

BACKGROUND: The aim of our study was to determine the maximum tolerated dose of paclitaxel combined with a fixed dose of gemcitabine and vinorelbine in the treatment of non-small-cell lung cancer (NSCLC) and to evaluate in a phase II trial the efficacy of this combination. PATIENTS AND METHODS: Sixty-two patients with stage IIIB/IV NSCLC were treated with paclitaxel in escalating doses from 40-80 mg/m(2) combined with gemcitabine and vinorelbine at fixed doses of 1000 mg/m(2) and 25 mg/m(2), respectively. All drugs were given intravenously on day 1 and 8 every 3 weeks. RESULTS: In a phase I trial, carried out on 21 patients, grade 4 neutropenia, as dose-limiting toxicity, occurred at the dosage level of paclitaxel 80 mg/m(2). In a phase II trial, with paclitaxel administered at 70 mg/m(2), 27 out of 41 (66%) assessable patients responded (10% complete responses and 56% partial responses). Objective response was observed in 13 of 16 patients (81%) with stage IIIB disease and in 14 of 25 (56%) with stage IV disease. The median time to treatment failure was 26 weeks (range 3-72 weeks; 32 weeks and 20 weeks for stages IIIB and IV, respectively) and median survival 62 weeks (range 4-176 weeks; 72 weeks and 56 weeks for stages IIIB and IV, respectively). One-year survival was 64% for all patients (72% for patients with stage IIIB and 52% for those with stage IV). Grade 3 and 4 neutropenia were observed in 11 (27%) and seven (17%) cases, respectively; grade 3 thrombocytopenia was observed in three patients (7%) and grade 3 anemia in four patients (10%). The most relevant non-hematological toxicity was grade 2/3 asthenia, which was observed in 12 patients (29%). Alopecia was almost universal, whereas nausea and vomiting were absent. CONCLUSIONS: The combination of paclitaxel, gemcitabine and vinorelbine is effective and tolerable in the treatment of NSCLC. The high activity and low toxicity of this regimen warrant randomized studies with platinum-containing combinations.

A weekly regimen of cisplatin, paclitaxel and topotecan with granulocyte-colony stimulating factor support for patients with extensive disease small cell lung cancer: a phase II study.

The present study was aimed at defining the antitumour activity of the cisplatin-paclitaxel-topotecan (CPT) weekly administration with G-CSF support in chemo-naive SCLC patients with extensive disease (ED-SCLC). Chemonaive ED-SCLC patients received cisplatin 40 mg/m(2), paclitaxel 85 mg/m(2), and topotecan 2.25 mg/m(2)weekly, with G-CSF (5 microg/kg days 3-5) support, for a maximum of 12 weeks. 37 patients were treated, for a total of 348 cycles delivered. 8 complete responses (22%) and 22 partial responses (59%) were recorded, giving an 81% [95% CI = 65-92%] ORR. At a 13-month (range, 4-26) median follow-up, median progression-free and overall survival were 8 months and 12.5 months, with 1-year and 2-year projected survivals of 55% and 21%, respectively. No toxic deaths occurred. Grade 4 neutropenia and thrombocytopenia occurred in 6 and 3 patients, respectively. Only one case of neutropenic sepsis was recorded, while haemorrhagic thrombocytopenia was never observed. Diarrhoea, paraesthesias and fatigue were the main nonhaematologic toxicities being severe in 6, 2 and 10 patients, respectively. The weekly CPT combination with G-CSF support represents a well tolerated therapeutic approach in chemo-naive ED-SCLC patients. The activity rate seems at least similar to that achievable with the standard front-line approaches.

Gemcitabine plus vinorelbine yields better survival outcome than vinorelbine alone in elderly patients with advanced non-small cell lung cancer. A Southern Italy Cooperative Oncology Group (SICOG) phase III trial.

OBJECTIVE: This phase III study was aimed at evaluating whether the addition of gemcitabine (G) to vinorelbine (V) could improve the survival and quality of life (QoL) of elderly patients with advanced NSCLC. PATIENTS AND METHODS: Patients with advanced NSCLC, aged >or=70 years, were randomly allocated to receive V 30 mg/m(2) on days 1 and 8 every 3 weeks or G 1200 mg/m(2) plus V 30 mg/m(2) on days 1 and 8 every 3 weeks. Survival was the main end point of the study. The estimated sample size was 120 patients per arm, but an interim analysis of survival was planned on the first 60 patients per arm. RESULTS: In May 1999, an interim analysis was performed with the survival data of the first 120 eligible patients (V(arm)=60, G+V(arm)=60). Forty-nine patients had stage IIIB disease and 71 patients stage IV disease, median potential follow-up of 14 months (range; 3-22), 93 patients had died (G+V(arm)=41, V(arm)=52). Median survival time (MST) was 29 weeks and projected 1-year survival was 30% in the G+V(arm); these values were 18 weeks and 13% in the V(arm). At multivariate Cox analysis, the risk of death in the G+V(arm) compared with V(arm) was 0.48 (95% C1=0.29-0.79; P<0.01). Combination therapy was also associated with a clear delay in symptom and QoL deterioration. The ORR was 22 and 15% in the G+V and V(arms), respectively. Toxicity was not irrelevant in both arms. CONCLUSIONS: G+V treatment is associated with a significantly better survival than V alone in elderly NSCLC patients. The magnitude of the difference justifies the early closure of the study. The G+V regimen is now the SICOG reference regimen in this type of patients.

A phase II study of induction chemotherapy with gemcitabine (G) and cisplatin (P) in locally advanced non-small cell lung cancer: interim analysis.

BACKGROUND: Gemcitabine-cisplatin (GP) combination is one of the most active and well tolerated regimens in advanced non-small cell lung cancer (NSCLC). The aim of this study is to evaluate the activity and toxicity of the GP regimen as a 21-day schedule in patients (pts) with stage IIIAN2-IIIB NSCLC. PATIENTS AND METHODS: From October 1997 to July 2000, 47 pts entered the study: 43 were eligible (40 men and three women); median age was 61 years (range 45-73); ECOG PS 0-1; histology was squamous (20 pts), adenocarcinoma (12 pts), large cell (five pts), and undifferentiated (six pts); stage was IIIAN2 (14 pts, 32.56%), and IIIB (29 pts, 67.44%). Malignant pleural effusion or superior vena cava syndrome was criteria of exclusion. Induction treatment consisted of three cycles of GP (G 1250 mg/m(2) i.v. on days 1 and 8, and P 100 mg/m(2) on day 8 every 3 weeks). Responding and stable pts underwent surgery (S) and/or radiotherapy (RT). RESULTS: Following a minimum of two cycles, 39 pts were evaluable for response and 42 for toxicity. Two pts had complete responses (CR; 5.2%), 24 had partial response (PR; 61.5%), eight had stable disease (SD; 20.5%), and five had progressive disease (PRO; 12.8%). WHO grades 3 and 4 anaemia, neutropenia and thrombocytopenia were observed in two, four and two pts, respectively; non-haematological toxicity was moderate. After induction, stable and responding pts received either RT (18 pts) or S+RT (13 pts). Among the 16 resected pts, a radical complete resection was possible in 13 cases (81.3%), whereas tumour down-staging was observed in nine pts (56.2%). CONCLUSION: GP, as a 3-week neoadjuvant schedule, appears a safe and active regimen.

Gemcitabine plus vinorelbine versus vinorelbine alone in elderly patients with advanced non-small-cell lung cancer.

PURPOSE: To evaluate whether the addition of gemcitabine (G) to vinorelbine (V) improves survival and quality of life (QoL) among elderly patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients with NSCLC aged >/= 70 years with advanced disease were randomly allocated to receive V 30 mg/m(2) on days 1 and 8 every 3 weeks or G 1,200 mg/m(2) + V 30 mg/m(2) on days 1 and 8 every 3 weeks. The estimated sample size was 120 patients per arm, but an interim analysis of survival was planned based on the first 60 patients per arm. RESULTS: In May 1999, the survival data were analyzed of 120 eligible patients (V group = 60; G + V group = 60) who had been randomized from June 1997 to February 1999. Forty-nine patients had stage IIIB disease, and 71 had stage IV. At a median potential follow-up of 14 months (range, 3 to 22 months), 93 patients had died (G + V group = 41; V group = 52). In the G + V group, median survival time was 29 weeks and projected 1-year survival was 30%; these values were 18 weeks and 13% in the V group. According to multivariate Cox analysis, the risk of death in the G + V arm compared with the V arm was 0.48 (95% confidence interval, 0. 29 to 0.79; P <.01). Combination therapy was also associated with a clear delay in symptom and QoL deterioration. The overall response rates were 22% and 15% in the G + V and V groups, respectively. CONCLUSION: In elderly patients with NSCLC, G + V treatment is associated with significantly better survival than is V alone.

Phase I/II study of gemcitabine plus vinorelbine as first-line chemotherapy of non-small-cell lung cancer.

PURPOSE: To determine the maximum-tolerated dose of gemcitabine when combined with a fixed dose of vinorelbine in the treatment of non-small-cell lung cancer (NSCLC) and to evaluate in a phase II trial the activity of this combination. PATIENTS AND METHODS: Sixty-eight patients with stage IIIB/IV NSCLC were treated with vinorelbine at fixed dose of 30 mg/m(2) intravenously and gemcitabine at increasing dose levels from 800 to 1,500 mg/m(2) intravenously on days 1 and 8 every 3 weeks. RESULTS: In phase I, dose-limiting toxicity occurred at the dosage of 1,500 mg/m(2) gemcitabine, with three of five patients developing grade 4 thrombocytopenia. In phase II, with gemcitabine at 1,200 mg/m(2), 19 (36%) of 52 assessable patients responded. Objective response was observed in 11 (39%) of 28 patients with stage IIIB disease and in eight (33%) of 24 patients with stage IV. The median time to progression was 29 weeks (range, 2 to 41 weeks; 35 weeks and 16 weeks for stages IIIB and IV, respectively), and median survival was 54 weeks (range, 2 to 84+ weeks; 63 weeks and 42 weeks for stages IIIB and IV, respectively). One-year survival was 64% for patients with stage IIIB disease and 29% for those with stage IV. Clinical benefit response was observed in 29 (59%) of 49 assessable patients. Grade 4 leukopenia and thrombocytopenia were uncommon (6% and 8% of cases, respectively); however, grade 3/4 leukothrombocytopenia occurred more frequently in patients aged more than 70 years (52% and 24%, respectively). CONCLUSION: The combination of vinorelbine and gemcitabine is effective and tolerable in the treatment of NSCLC, thus deserving randomized trials with cisplatin combination regimens.

Randomized trial comparing cisplatin, gemcitabine, and vinorelbine with either cisplatin and gemcitabine or cisplatin and vinorelbine in advanced non-small-cell lung cancer: interim analysis of a phase III trial of the Southern Italy Cooperative Oncology Group.

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.

Interim analysis of a phase III trial comparing cisplatin, gemcitabine, and vinorelbine vs. either cisplatin and gemcitabine or cisplatin and vinorelbine in advanced non small-cell lung cancer. A Southern Italy Cooperative Oncology Group Study.

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 <or= 70 years, and with Eastern Cooperative Oncology Group performance status (ECOG PS) <or= 1, were randomly allocated to receive: cisplatin, 50 mg/m2 plus gemcitabine, 1000 mg/m2 plus vinorelbine, 25 mg/m2 (PGV) on days 1 and 8 every 3 weeks; cisplatin, 100 mg/m2 on day 1 plus gemcitabine, 1000 mg/m2 (PG) on days 1, 8, and 15 every 4 weeks; cisplatin, 120 mg/m2 on days 1 and 29 plus vinorelbine, 30 mg/m2/week (PV). At the planned interim analysis, the MST of patients in the PGV, PG, and PV arms was 51, 42, and 35 weeks, respectively. The hazard of death (Cox analysis) for patients receiving PGV compared with those receiving PV was 0.35 (95% confidence index [CI], 0.16-0.77, P = 0.0058). The response rate was 47% in the PGV arm, 30% in the PG arm, and 25% in the PV arm. Severe neutropenia (75% vs. 45%), and vomiting (50% vs. 15%) significantly affected more patients in the PV than in the PGV arm. Since the difference in survival met early stopping rules, accrual to the PV arm was suspended. Enrollment still continues in the PGV and PG arms to ascertain whether the triplet regimen has a more significant effect on survival than that produced with the PG regimen.

Receptor imaging with 111In-pentreotide and 123I-methoxybenzamide, and inhibition tests with octreotide and bromocriptine of mixed growth hormone/prolactin-secreting pituitary tumors.

We have performed pituitary scintigraphy with 111In-pentreotide (OCT), a somatostatin analogue, and with metoxybenzamide (IBZM) by 123I-IBZM in two patients affected by mixed growth hormone/prolactin-secreting pituitary tumors. Short-term growth hormone (GH) inhibition by a single injection of OCT (100 micrograms s.c.), and short-term prolactin (PRL) inhibition by oral administration of 2.5 mg of bromocriptine (BCR), were also performed in both patients. The first patient, a 26 year old man, showed intense tumor uptake of 123I-IBZM scintigraphy, whereas 111In-OCT scintigraphy showed moderate tumor uptake. Five hours after the BCR inhibition test, a fall of 83% in PRL plasma levels (from 8,336 micrograms/L to 1,417 micrograms/L), and of 91.6% in GH plasma levels (from 39.5 micrograms/L to 3.3 micrograms/L) were observed. OCT inhibition test suppressed GH plasma levels from 36 micrograms/L to 3.5 micrograms/L. The patient was submitted to treatment with BCR and OCT. A dramatic shrinkage of the tumor was seen after six months of therapy. The lesion disappeared one year after the start of therapy. The second patient, a 64 year old man, showed intense uptake at 111In-OCT scintigraphy, while 123I-IBZM uptake was not observed. A test dose of BCR resulted in an acute fall of PRL (from 145 micrograms/L to 118 micrograms/L), but not of GH. A test dose of OCT decreased the GH plasma level from 61 micrograms/L to 4.5 micrograms/L. The patient was submitted to treatment with BCR and OCT that resulted in a computed tomography and magnetic resonance imaging decrease of 45% of tumor volume one year after the start of therapy. Our results suggest that both suppression tests with OCT and BCR, and scintigraphic studies in vivo with 123I-IBZM and 111In-OCT can be predictive for the effectiveness of therapies with dopamine agonists and/or SS-analogs in patients with mixed PRL/GH-secreting pituitary tumors. Further studies are required to evaluate the role of suppressive tests in selecting patients for appropriate clinical treatments.

Cisplatin-topotecan-paclitaxel weekly administration with G-CSF support for ovarian and small-cell lung cancer patients: a dose-finding study.

PURPOSE: Paclitaxel (PTX) and topotecan (TPT) have shown promising antitumor activity in both ovarian cancer (OC) and small-cell lung cancer (SCLC) patients. This phase I study was aimed at determining the maximum tolerable dose (MTD) of TPT given weekly over 30 min in combination with fixed doses of cisplatin (CDDP) and (PTX), and with G-CSF support. PATIENTS AND METHODS: Forty-four patients with OC (19) or SCLC (25), either chemo-naïve (20) or pretreated (24) received CDDP 40 mg/m2, PTX 85 mg/m2 (one-hour infusion) and escalating TPT doses (starting from 0.75 mg/m2) in a 30-min infusion in weekly administration. Filgrastim 5 mg/kg was administered on days 3 to 5 of each week. RESULTS: Eight different dose levels were tested for a total of 295 delivered cycles. The dose escalation was interrupted at the TPT dose of 2.50 mg/m2. No toxic deaths occurred in this study. Grade 3 to 4 neutropenia, thrombocytopenia, and anemia occurred in 15 patients (36 cycles), seven patients (15 cycles), and four patients (five cycles), respectively. Severe vomiting and diarrhoea occurred in seven and four patients. Peripheral neuropathy was recorded in 11 patients (42 cycles), but it was never severe. An overall 11 of 19 (58%) OC and 11 of 25 (44%) SCLC patients obtained objective responses. Eight patients showed complete responses (three OC and three SCLC). Among the 20 chemo-naïve patients, 9 of 11 (82%) OC and seven of nine (78%) SCLC responded. CONCLUSIONS: The CDDP/TPT/PTX weekly administration with filgrastim support represents a well-tolerated and active therapeutic approach in both chemo-naïve and pretreated OC and SCLC patients. A weekly dose of TPT of 2.25 mg/m2 is recommended for the phase II study.

No evidence of fluid absorption during continuous low-pressure transurethral resection of the prostate: assessment by measuring expiratory breath ethanol concentrations.

OBJECTIVE: Measurement of the ethanol concentration in expired breath during transurethral resection of the prostate (TURP). METHODS: TURP is a noninvasive method to estimate the amount of irrigant absorbed. The expiratory breath ethanol concentrations (EBEC) were measured with a standard alcohol breath analyzer in 35 patients in the course of TURP. All interventions were performed with a 27-french continuous flow resectoscope using a solution of 1. 5% glycine + 1% ethanol as irrigating fluid. Serum sodium and osmolality were measured pre- and postoperatively. No patient developed signs of transurethral resection syndrome; no significant changes in serum sodium, osmolality and EBEC were found throughout the operation. CONCLUSION: Absorption of irrigant fluid during TURP with continuous low-pressure irrigation seems to be extremely slight (if not absent) as measured by expired breath ethanol method.

Exhaled nitric oxide concentrations during treatment of wheezing exacerbation in infants and young children.

While it is known that exhaled nitric oxide (ENO) is increased in adults and school children with asthma exacerbation probably as an expression of disease activity, no studies have investigated whether this phenomenon also occurs in infants and young children with recurrent wheeze exacerbation. We measured ENO in 13 young children (mean age 20.2 mo) with recurrent wheeze (Group 1) during an acute episode and after 5 d of oral prednisone therapy. ENO was measured also in nine healthy control subjects (Group 2) (mean age 16.9 mo) and in six children with a first-time viral wheezy episode (Group 3) (mean age 11 mo). To measure ENO, infants inhaled NO-free air via a face mask from a reservoir and, through a nonrebreathing valve, exhaled in a collecting bag that was analyzed by chemiluminescence. To address the question of whether the levels of ENO collected in the bag are a reflection of the pulmonary airway, ENO determinations were performed in two healthy infants before and after tracheal intubation for elective surgery. During the acute episode of wheezing the mean (+/- SEM) value of ENO in children with recurrent wheeze (Group 1) was 14.1 +/- 1.8 ppb, almost threefold higher than in healthy control subjects (5.6 +/- 0.5 ppb, p < 0.001). After steroid therapy we found a mean fall of 52% in ENO (5.9 +/- 0.7 ppb, p < 0.01) compared with baseline values. ENO values measured before and after intubation in two infants were 6 ppb and 5 ppb in one child and 7 ppb and 6 ppb in the other one. The mean value of ENO of children with first-time wheeze (Group 3) was 8.3 +/- 1.3 ppb, significantly lower (p < 0.05) than the value of children with recurrent wheeze (Group 1). In conclusion, we describe a method to measure ENO in young children and show that infants with recurrent wheeze have elevated levels of ENO during exacerbation that rapidly decrease after steroid therapy. This suggests that, in these children, airway inflammation could be present at a very early stage.

Cisplatin, gemcitabine, and vinorelbine combination therapy in advanced non-small-cell lung cancer: a phase II randomized study of the Southern Italy Cooperative Oncology Group.

PURPOSE: In a previous phase I study cisplatin (CDDP), gemcitabine (GEM), and vinorelbine (VNR) combination therapy was safe and very active in patients with non-small-cell lung cancer (NSCLC). This study was aimed at better defining the activity and toxicity of this regimen. PATIENTS AND METHODS: One hundred eleven chemotherapy-naive patients, age < or = 70 years, with stage IIIB or IV NSCLC and a performance status of 0 or 1 (Eastern Cooperative Oncology Group scale) were randomized to two treatment arms. Patients on arm A received CDDP 50 mg/m2, GEM 1,000 mg/m2, and VNR 25 mg/m2 on days 1 and 8 of an every-3-weeks cycle (57 patients). Patients on arm B received CDDP 80 mg/m2, epirubicin 80 mg/m2, and vindesine 3 mg/m2, all delivered on day 1 every 4 weeks, plus lonidamine orally 150 mg three times daily (54 patients). In December 1996, randomization was stopped early, and an additional 30 patients were treated with the experimental regimen to obtain a more accurate estimation of its activity rate. RESULTS: Among 87 patients who received the CDDP-GEM-VNR combination, four complete responses (CRs) and 46 partial responses (PRs) were observed, for an overall response rate of 57% (95% confidence interval [CI], 46% to 68%). Two CRs and 18 PRs were recorded among 54 patients on arm B, giving a 37% activity rate (95% CI , 24% to 51%). After a median follow-up duration of 19 months, the median progression-free and overall survival durations were 32 and 50 weeks in arm A, and 18 and 33 weeks in arm B, respectively. World Health Organization grade 3 to 4 neutropenia and thrombocytopenia occurred in 46% and 14% of patients in arm A and in 22% and 11% of those in arm B, respectively. Severe nonhematologic toxicity was uncommon in both arms. CONCLUSION: The CDDP-GEM-VNR combination is a highly effective treatment for patients with advanced NSCLC and has a manageable toxicity. A phase III trial comparing this new combination with both CDDP-VNR and CDDP-GEM regimens is underway.
