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.     

Weekly gemcitabine and cisplatin chemotherapy: a well-tolerated but ineffective chemotherapeutic regimen in advanced pancreatic cancer patients. A report from the Italian Group for the Study of Digestive Tract Cancer (GISCAD).

BACKGROUND: This phase II study was initiated to determine the activity and toxicity of a combination of gemcitabine (GEM) and cisplatin (CDDP) in patients with pancreatic cancer. PATIENTS AND METHODS: CDDP 35 mg/m(2) was given as a 30-min infusion and GEM 1000 mg/m(2) as a 30-min infusion. Both drugs were administered once weekly for 2 consecutive weeks out of every 3 weeks to chemonaive patients with locally advanced or metastatic pancreatic cancer. RESULTS: Forty-five advanced pancreatic cancer patients received this regimen for a total of 180 cycles of chemotherapy. One complete and four partial responses have been observed for an overall response rate of 9% (95% confidence interval 10% to 11%). Twenty-one patients (46%) had stable disease and 19 progressed on therapy. The median time to progression was 3.6 months, with a median survival of 5.6 months. A clinical benefit was obtained in nine of 37 patients (24%). Side-effects were mainly represented by hematological toxicity. Grade 3/4 WHO toxicities included neutropenia (6% of the patients) and thrombocytopenia (11%). The dose of GEM and CDDP was reduced in 14 patients (31%) and treatment was delayed in 10 patients (22%). CONCLUSIONS: Our results in terms of response rate, clinical benefit and survival do not support an advantage for the combination of GEM and CDDP given by this schedule.     

Bi-weekly administration of gemcitabine plus vinorelbine in elderly patients with advanced non-small-cell lung cancer: multicenter phase II trial

PURPOSE: Gemcitabine (GEM) and vinorelbine (VNR) have demonstrated activity as a first-line treatment in elderly patients with advanced non-small-cell lung cancer (NSCLC). We conducted a multicenter phase II trial to evaluate the efficacy and toxicity of bi-weekly administration of GEM plus VNR in elderly patients with advanced NSCLC. PATIENTS AND METHODS: Forty-six chemotherapy-naive elderly (age: >or=70 years) NSCLC patients were enrolled. Patients were eligible if they had histologically or cytologically confirmed unresectable NSCLC with measurable and/or assessable disease. Patients received GEM (1000 mg/m2) and VNR (25 mg/m2) every 2 weeks. RESULTS: The objective response rate of this treatment was 22.7% (95% confidence interval (CI), 10.3-35.1%), median survival time was 310 days, and median time to progression was 133 days. The one-year survival rate was 40.9% (95% CI, 26.3-55.4%), and most adverse events were mild. Only three (6.8%) patients needed to omit GEM because of grade 4 neutropenia or due to physician judgment. No patients suffered treatment-related death. CONCLUSIONS: Bi-weekly administration of GEM plus VNR in elderly patients was an effective, feasible and well-tolerated treatment schedule.     

Combination therapy with docetaxel and low dose of cisplatin in elderly patients with advanced non-small cell lung cancer: multicenter phase II study

Purpose  To determine the efficacy and safety of the combination therapy with docetaxel and cisplatin (CDDP) at low doses in elderly patients with advanced NSCLC. Patients and methods  A total of 42 patients aged ≥70 years with previously untreated advanced NSCLC received docetaxel 75 mg/m² plus CDDP 50 mg/m² on day 1. The regimen was repeated every 21 days. Patients received a minimum of three courses unless progressive disease was detected. Results  By intent-to-treat analysis, the overall response rate was 31% (95% CI, 17.8–47.2%). A total of 18 patients (43%) had stable disease and 11 (26%) progressed. Median time to progression was 5.2 months. Overall median survival was 8.9 months, with 1-year actuarial survival rate of 41%. Eastern Cooperative Oncology Group performance status was improved in 18 patients (43%). The chemotherapy regimen was well tolerated. A total of 11 patients (26%) had grade 3/4 adverse events: 7 (17%) neutropenia (one of them was diagnosed with febrile neutropenia), 3 (7%) asthenia, 3 (7%) nausea/vomiting, 1 (2%) diarrhea, 1 (2%) thrombocytopenia and 1 (2%) neurotoxicity. No death due to toxicity was seen. Conclusion  The combination of low-dose CDDP and docetaxel for elderly patients with advanced NSCLC is an efficient and well-tolerated chemotherapeutic approach.     

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.     

Gemcitabine and cisplatin in the treatment of elderly patients with advanced non-small cell lung cancer: impact of comorbidities on safety and efficacy outcome

The aim of the study was to describe in detail the impact of aging and comorbidities on safety and efficacy of gemcitabine-cisplatin in the subset of elderly with advanced NSCLC. We report the results of our study which enrolled patients aged over 65 years or older. This study included 46 patients consecutively admitted to our Department. Treatment consisted of gemcitabine 1250 mg/m2 on days 1 and 8, and cisplatin 75 mg/m2 on day 2, of a 21-day cycle. The Charlson score method was chosen to evaluate the conditions of comorbidity. All patients were evaluable for toxicity and 44 for activity. A total of 128 courses were administered, with a median of 3 courses per patient and a dose-intensity of 93% and 88% for gemcitabine and cisplatin, respectively. Grade 3-4 neutropenia (22% of patients) and grade 3 asthenia (4.5%), emesis (4.5%) and nephrotoxicity (4.5%) were the most severe adverse events. Univariate analysis of toxicity did not show any significant difference among all groups. The overall response rate was 45.6% (95% CI, 31.3-60). At a median follow up of 13 months, the median and progression-free survival were 15 and 8 months, respectively. The multivariate analysis resulted in objective response and disease control being predictive of longer survival. The combination of gemcitabine and cisplatin appears to be an effective and tolerated regimen for elderly patients with advanced NSCLC, regardless of aging and condition of comorbidities. Prospective randomized trials based on specific geriatric assessment are required to obtain compelling information for the optimal management of elderly patients with advanced NSCLC.     

Gemcitabine plus vinorelbine in nonsmall cell lung carcinoma patients age 70 years or older or patients who cannot receive cisplatin. Oncopaz Cooperative Group.

BACKGROUND: Although the prevalence of nonsmall cell lung carcinoma (NSCLC) is high among elderly patients, few data are available regarding the efficacy and toxicity of chemotherapy in this group of patients. Recent reports indicate that single agent therapy with vinorelbine (VNB) or gemcitabine (GEM) may obtain a response rate of 20-30% in elderly patients, with acceptable toxicity and improvement in symptoms and quality of life. In the current study the efficacy and toxicity of the combination of GEM and VNB in elderly patients with advanced NSCLC or those with some contraindication to receiving cisplatin were assessed. METHODS: Forty-nine patients with advanced NSCLC were included, 38 of whom were age >/= 70 years and 11 were age < 70 years but who had some contraindication to receiving cisplatin. All patients were evaluable for response and toxicity. Treatment was comprised of VNB, 25 mg/m(2), plus GEM, 1000 mg/m(2), both on Days 1, 8, and 15 every 28 days. Patients received a minimum of three courses unless progressive disease was detected. RESULTS: One hundred sixty-five courses were administered, with a median of 3. 6 courses per patient. The overall response rate was 26% (95% confidence interval, 15-41%). Two patients attained a complete response (4%) and 11 patients (22%) achieved a partial response. Eastern Cooperative Oncology Group performance status improved in 35% of those patients with an initial value > 0, whereas relief of at least 1 symptom without worsening of other symptoms was noted in 27 patients (55%). The median time to progression was 16 weeks and the 1-year survival rate was 33%. Toxicity was mild. Six patients (12%) had World Health Organization Grade 3-4 neutropenia, 2 patients (4%) had Grade 3-4 thrombocytopenia, and 2 patients (4%) had Grade 3 neurotoxicity. Three patients with severe neutropenia (6%) died of sepsis. The median age of those patients developing Grade 3-4 neutropenia was significantly higher than that of the remaining patients (75 years vs. 72 years; P = 0.047). CONCLUSIONS: The combination of GEM and VNB is moderately active and well tolerated except in patients age >/= 75 years. This age group had an increased risk of myelosuppression. Therefore the prophylactic use of granulocyte-colony stimulating factor should be considered with this treatment. New chemotherapy combinations with higher activity and lower toxicity are needed for elderly patients with advanced NSCLC.     

Gemcitabine and Cisplatin in the Treatment of Elderly Patients with Advanced Non-Small Cell Lung Cancer: Impact of Comorbidities on Safety and Efficacy Outcome

Abstract

The aim of the study was to describe in detail the impact of aging and comorbidities on safety and efficacy of gemcitabine-cisplatin in the subset of elderly with advanced NSCLC. We report the results of our study which enrolled patients aged over 65 years or older. This study included 46 patients consecutively admitted to our Department. Treatment consisted of gemcitabine 1250 mg/m² on days 1 and 8, and cisplatin 75 mg/m² on day 2, of a 21-day cycle. The Charlson score method was chosen to evaluate the conditions of comorbidity.

All patients were evaluable for toxicity and 44 for activity. A total of 128 courses were administered, with a median of 3 courses per patient and a dose-intensity of 93% and 88% for gemcitabine and cisplatin, respectively. Grade 3-4 neutropenia (22% of patients) and grade 3 asthenia (4.5%), emesis (4.5%) and nephrotoxicity (4.5%) were the most severe adverse events. Univariate analysis of toxicity did not show any significant difference among all groups. The overall response rate was 45.6% (95% CI, 31.3-60). At a median follow up of 13 months, the median and progression-free survival were 15 and 8 months, respectively. The multivariate analysis resulted in objective response and disease control being predictive of longer survival.

The combination of gemcitabine and cisplatin appears to be an effective and tolerated regimen for elderly patients with advanced NSCLC, regardless of aging and condition of comorbidities. Prospective randomized trials based on specific geriatric assessment are required to obtain compelling information for the optimal management of elderly patients with advanced NSCLC.

两种不同方案治疗晚期非小细胞肺癌的疗效比较(英文)

Objective: The aim of this study was to analyze and compare the recent efficacy and toxicity of a three-drug platinum-based regimen (A regimen): [cisplatin (DDP) + gemcitabine (GEM) + vinorelbine (NVB)] and a two-drug combination without a platinum drug (B regimen): GEM + NVB, which were used to treat 55 advanced non-small cell lung cancer (NSCLC) patients, in a bid to provide a guidance for clinical treatment. Methods: Twenty-four cases of advanced NSCLC (stage III-IV) patients were treated with A regimen ...     

Functional polymorphisms of the microsomal epoxide hydrolase gene: a reappraisal on a early-onset lung cancer patients series

As concomitant chemoradiotherapy for stage III NSCLC is associated with survival advantage in comparison to a sequential approach, we conducted a phase III randomised study aiming to determine the best sequence and safety of chemotherapy (CT) and chemoradiotherapy (CT-RT), using a regimen with cisplatin (CDDP), gemcitabine (GEM) and vinorelbine (VNR). Unresectable stage III NSCLC patients received CDDP (60 mg/m(2)), GEM (1g/m(2), days 1 and 8) and VNR (25mg/m(2), days 1 and 8) with reduced dosage of GEM and VNR during radiotherapy (66Gy). Two cycles of CT with radiotherapy followed by two further cycles of CT alone were administered in arm A or the reverse sequence in arm B. The study was prematurely closed for poor accrual due to administrative problems. Forty-nine eligible patients were randomised. Response rates and median survival times were, respectively 57% (95% CI: 36-78%) and 17 months (95% CI: 9.3-24.6 months) in arm A and 79% (95% CI: 64-94%) and 23.9 months (95% CI: 13.3-34.5 months) in arm B (p>0.05). Chemotherapy dose-intensity was significantly reduced in arm A. Grade 3-4 oesophagitis occurred in 5 patients. One case of grade 5 radiation pneumonitis was observed. In conclusion, chemoradiotherapy with CDDP, GEM and VNR appears feasible as initial treatment or after induction chemotherapy. Consolidation chemoradiotherapy seems less toxic with a better observed response rates and survival although no valid conclusion can be drawn from the comparison of both arms.     

Efficacy of the combination of cisplatin with either gemcitabine and vinorelbine or gemcitabine and paclitaxel in the treatment of locally advanced or metastatic non-small-cell lung cancer: a phase III randomised trial of the Southern Italy Cooperative Oncology Group (SICOG 0101).

BACKGROUND: Triplet regimens were occasionally reported to produce a higher response rate (RR) than doublets in locally advanced or metastatic non-small-cell lung cancer (NSCLC). This trial was conducted to assess (i) whether the addition of cisplatin (CDDP) to either gemcitabine (GEM) and vinorelbine (VNR) or GEM and paclitaxel (PTX) significantly prolongs overall survival (OS) and (ii) to compare the toxicity of PTX-containing and VNR-containing combinations. PATIENTS AND METHODS: Stage III or IV NSCLC patients were randomly assigned to (i) GEM 1000 mg/m(2) and VNR 25 mg/m(2) on days 1 and 8 (GV arm); (ii) GEM 1000 mg/m(2) and PTX 125 mg/m(2) on days 1 and 8 (GT arm); (iii) GV plus CDDP 50 mg/m(2) on days 1 and 8 (PGV arm); and (iv) GT plus CDDP 50 mg/m(2) on days 1 and 8 (PGT arm). Treatments were repeated every 3 weeks for a maximum of six cycles. RESULTS: A total of 433 (stage III, 160; stage IV, 273) patients were randomly allocated to the study. RR was 48% [95% confidence interval (CI), 42% to 54%] for triplets and 35% (95% CI, 32% to 38%) for doublets (P = 0.004). Median progression-free survival (6.1 versus 5.5 months, P = 0.706) and median OS (10.7 versus 10.5 months, P = 0.379) were similar. CDDP significantly increased the occurrence of severe neutropenia (35% versus 13%), thrombocytopenia (14% versus 4%), anaemia (9% versus 3%), vomiting (6% versus 0.5%), and diarrhoea (6% versus 2%). Conversely, frequency of severe neutropenia (30% versus 17%) and thrombocytopenia (11% versus 6%) was significantly higher with VNR-containing regimens. CONCLUSIONS: Adding CDDP to GV or GT significantly increased RR, but did not prolong the OS of patients. Among doublets, the GT regimen should be preferred in view of its better safety profile.     

Cisplatin and vinorelbine as second-line chemotherapy in patients with advanced non-small cell lung cancer (NSCLC) resistant to taxol plus gemcitabine

The aim of the study was to evaluate the activity of cisplatin (CDDP) plus vinorelbine (VNR) in patients with advanced non-small cell lung cancer (NSCLC) progressing after paclitaxel plus gemcitabine. Treatment consisted of CDDP 80 mg/m(2) administered on day 1 and VNR 25 mg/m(2) administered on day 1 and 8, repeated every 3 weeks. Nine patients who relapsed after partial response and eight patients refractory to prior CT received a minimum of two treatment cycles: three patients achieved a PR (18%; 95% CI: 4-43%), four had stable disease and 10 had disease progression. All responses were observed among the nine patients responsive to prior treatment. Median survival was 35 weeks. No patients required dose-reduction, treatment discontinuation or delay because of toxicity. Our results indicate a reasonable antitumor efficacy and no relevant toxicity of a second-line CDDP-based chemotherapy in patients with advanced NSCLC. We recommend the use of this regimen for patients not refractory to primary treatment.

Chemotherapy with low-dose CDDP and continuous 5-FU for the treatment of advanced gastric cancers]

INTRODUCTION: 5-fluorouracil (5-FU) has been widely used for the treatment of gastrointestinal cancers. On the basis of recent findings, low-dose Cisplatin (CDDP) and continuous venous infusion of 5-FU have shown additive or synergistic antitumor effects in experimental models. We evaluated clinical effects of low-dose CDDP and 5-FU (low-dose FP therapy) in patients with advanced gastric cancers. PATIENTS AND METHODS: In December 1993 and June 1998, 52 patients with advanced gastric cancer were entered in this study. Patients were considered eligible if they had a bidimensionally measurable tumor. 5-FU (160 mg/m2/day) was continuously infused over 24 hours using an implantable port, and CDDP (3 mg/m2/day) was infused for half an hour. The administration schedule consisted of 5-FU for 7 consecutive days and CDDP for 5 days followed by a 2-day rest every four weeks according to response and tolerance. RESULTS: Low-dose FP therapy was given 44 patients (85%). The response rate was 65.9% and median survival time was 249 days. The responder group showed good survival compared with the non-responder group. The regimen was tolerable, and the most common toxicity was anorexia (40.3%). Three patients suffered from grade 3 anorexia, leukopenia and mucositis. On the other hand, renal dysfunction occurred in 50% (two of four patients administered over 1,000 mg CDDP). These results raise the possibility that the dose-limiting factor of low-dose FP therapy may account for the total dosage of CDDP. CONCLUSION: Low-dose FP therapy promises to be effective in the clinical management of advanced gastric cancer.     

First line chemotherapy with planned sequential administration of gemcitabine followed by docetaxel in elderly advanced non-small-cell lung cancer patients: a multicenter phase II study

This multicenter phase II study evaluated, in chemonaive patients with stage IIIB-IV NSCLC, age >or=70 and with a performance status 0-2, the activity, efficacy and tolerability of planned sequential administration of gemcitabine 1200 mg m(-2) on days 1 and 8 every 3 weeks for three courses followed by three cycles of docetaxel 37.5 mg m(-2) on days 1 and 8 every 3 weeks, provided there was no evidence of disease progression. A total of 56 patients entered the study. According to intention-to-treat analysis, the objective response rate was 16.0% (95% CI 7.6-28.3%); 23 patients (41.0%) had stable disease and 24 patients (43%) had progressive disease. Five patients who had a stable disease after three courses of gemcitabine obtained a conversion to partial response by docetaxel. Median time to progression was 4.8 months (95% CI 3.6-6.0 months) and median duration of survival was 8.0 months (95% CI 5.6-10.5 months). The 1-year survival rate was 34%. No grade 4 haematological toxicity was observed and grade 3 neutropenia and thrombocytopenia were reported in 5.4 and 3.6% of the patients, respectively. Grade 3/4 mucositis and grade 3 diarrhoea, both occurred in 3.6% of the patients and grade 3 asthenia was observed in 9% of patients. One patient reported a grade 4 skin toxicity. No treatment-related deaths occurred. Sequential gemcitabine and docetaxel is a well-tolerated and effective regimen in elderly advanced NSCLC patients.     

Low-dose weekly paclitaxel as second-line treatment for advanced non-small cell lung cancer: a phase II study

PURPOSE: To assess the activity and toxicity of low-dose weekly paclitaxel in patients with non-resectable or metastatic non-small cell lung cancer (NSCLC) and who had disease recurrence or failure with previous chemotherapy. PATIENTS AND METHODS: Forty patients with NSCLC previously treated with platinum-based chemotherapy received weekly paclitaxel 80 mg/m(2) as a 1 h infusion. The median age was 63 years (range 42-77 years); 25 patients had Eastern Cooperative Oncology Group performance status (PS) 1 and 15 had PS 2. Thirty-one patients had stage IV disease and nine stage III (eight stage IIIB and one stage IIIA). RESULTS: A total of 364 weeks of treatment were administered (median 8 weeks, range 2-17 weeks). There were no episodes of grade 3 or 4 haematological toxicities. Severe non-haematological toxicity was uncommon: grade 1-2 asthenia in 50%; grade 1-2 motor neuropathy in 45% and grade 3 in 10%; grade 1-2 sensory neuropathy in 62% of patients. Alopecia was mild. The overall response rate was 37.5% (95% CI, 23.9-55): 2 CR, 13 PR, 15 SD, 8 PD, 2 NE. Median overall survival was 9.7 months (95% CI, 6.5-12.8). Median time to progression was 5.4 months (95% CI, 1.8-8.9). CONCLUSION: A low-dose weekly paclitaxel regimen had good clinical efficacy with low toxicity in this group of patients with poor prognosis. This regimen increases the therapeutic options available for second-line therapy in NSCLC patients.

Multicentre randomised phase III study comparing the same dose and schedule of cisplatin plus the same schedule of vinorelbine or gemcitabine in advanced non-small cell lung cancer

This study compares two cytotoxic regimens comprising the same dose and schedule of cisplatin (CP) plus vinorelbine (VNR) or gemcitabine (GEM) administered under the same schedule to patients with advanced non-small cell lung cancers (NSCLC). From April 1998 to February 2003, 285 patients were randomised to receive either VNR 25 mg/m(2) on days 1 and 8 as an intravenous (i.v.) bolus plus CP 75 mg/m(2) on day 1 (regimen A) or GEM 1200 mg/m(2) on days 1 and 8 as an i.v. 30-min infusion plus CP 75 mg/m(2) on day 1 (regimen B). Both treatments were recycled every 21 days. If no progression had occurred after six cycles, the patients continued to receive VNR or GEM monochemotherapy weekly. Cross-over of the two single agents was considered if disease progression occurred. Objective response (OR), time to progression (TTP) and overall survival (OS) were analysed according to the intention-to-treat principle. 272 patients were ultimately eligible (137 on A and 135 on B). Their main characteristics were: male/female ratio 214/58; median age 63 (range 32-77) years; median Karnofsky Performance Status (PS) 80 (range 70-100); stage IIIB 34%, stage IV 61%, recurrent disease 5%; histology - epidermoid 29%, adenocarcinoma 53%, other NSCLC 18%. The characteristics of the patients in the two arms were well matched. The following response rates were observed in regimens A and B, respectively: complete response (CR) 0.7% and 3.7%, partial response (PR) 31.9% and 22.2% (P = 0.321). Median CR+PR duration was 8 months in both arms. Clinical benefit represented by an improvement in symptoms was evident in 25.7% and 28.1%, respectively. Median TTP was 5 months in both arms and median OS 11 months in both arms. Grade III-IV neutropenia occurred in 30.7% and 17.7% of the patients in arms A and B, respectively (P = 0.017); thrombocytopenia occurred in 0% and 9.3% (P = 0.004), respectively. No difference in the incidence of anaemia was observed. Non-haematological toxicity was generally mild: a higher incidence of grade 1-2 peripheral neurotoxicity and grade 1-2 local toxicity with regimen A and grade 1-2 liver toxicity with regimen B was reported. A pharmaco-economic comparison showed a difference between the two doublets, principally due to the different costs of VNR and GEM. Under the study conditions the combination of VNR or GEM with the same dose and schedule of CP produced similar OR, clinical benefits, TTP and OS in advanced NSCLC, and only mild toxicological differences were observed. Pharmaco-economic evaluation favoured the CP + VNR doublet.     

Efficacy of low-dose CDDP and CPT-11 for patients with intestinal type of gastric adenocarcinoma

BACKGROUND: Preclinical studies have shown that irinotecan (CPT-11) and cisplatin (CDDP) can act synergistically. Several chemotherapy regimens combining CPT-11 and CDDP for advanced gastric cancer have been reported to demonstrate high response rates and high incidence of severe toxicity. PURPOSE: We conducted a combination chemotherapy regimen of low-dose CDDP and CPT-11 to prolong the time to progression with less toxicity. PATIENTS AND METHODS: Seven patients with histologically-confirmed intestinal type of gastric adenocarcinoma were enrolled in this study. All patients were male, and their age at diagnosis ranged from 52 to 76 with a mean age of 64.8. Six patients received combination chemotherapy with CPT-11 and CDDP after the gastrectomy (stage I b: 1, II : 3, III b: 1, IV: 1). Only chemotherapy was administered in one patient because of a far advanced primary lesion and metastatic tumors. Low-dose CDDP (20 mg/body) and CPT-11 (65 mg/m(2)) were administered intravenously once every two weeks. RESULTS: The overall response rate was 43% including 1 complete response and 2 partial responses. One patient had grade 3 myelosuppression. Other adverse reactions were mild. CONCLUSION: The combination of low-dose CDDP and CPT-11 has mild therapeutic toxicities and may achieve a prolonged median survival time in patients with intestinal- type gastric adenocarcinoma.
