Phase II study of the combination of vinorelbine and cisplatin in advanced non-small-cell lung cancer

Purpose To evaluate the efficacy and safety of combination chemotherapy with cisplatin and vinorelbine for the treatment of previously untreated patients with advanced non-small-cell lung cancer (NSCLC).Patients and methods Eligible patients were those with measurable NSCLC. They were treated with two or more cycles of a regimen consisting of vinorelbine 25 mg/m² on days 1 and 8 and cisplatin 80 mg/m² on day 1 every 3 weeks.Results A total of 45 patients were enrolled. The response rate was 51.1% (23/45; 95% CI 35.8% to 66.3%). The median survival was 286 days with a 1-year survival rate of 40%. The median number of treatment cycles was 2. The major toxic effect was neutropenia of grade 3 or higher (84%). Nonhematological toxicities, including vomiting (62%), were mild (grade 2 or less). There were no treatment-related deaths.Conclusion The high response rate and good tolerability proved this combination therapy to be a safe and effective treatment for advanced NSCLC.This work was supported in part by a grant-in-aid from the Ministry of Health and Welfare (Tokyo, Japan) and from the Second Term Comprehensive 10-Year Strategy for Cancer Control.     

Effect of vinorelbine, ifosfamide, and cisplatin combination chemotherapy in advanced non-small-cell lung cancer

Cisplatin-based chemotherapy is being tried in the treatment of nonoperable cases of non-small-cell lung cancer (NSCLC). However, the prognosis is unfavorable and to improve survival, clinical studies using various combinations of a variety of drugs as well as experimental material are in progress. We compared the efficacy and toxicities of combination chemotherapy using different doses of vinorelbine and ifosfamide with a constant dose of cisplatin in this study. Patients diagnosed with inoperable stage III or IV NSCLC between June 1997 and December 1998 were included. Cisplatin was administered at a constant dose of 80 mg/m2 on day 5, whereas vinorelbine on days 1 and 5 and ifosfamide on day 5 were administered in one of two different doses. In arm A, vinorelbine 25 mg/m2 and ifosfamide 3.0 g/m2 were administered. In arm B, vinorelbine 20 mg/m2 and ifosfamide 2.5 g/m2 were administered. Also, we reviewed for phase II and III studies that test 1) cisplatin, 2) vinorelbine monotherapy, and 3) vinorelbine/cisplatin/ifosfamide combination chemotherapy for stage IIIb-IV non-SCLC. Summation dose intensity (SDI) was calculated in each published and current study. Twenty patients in arm A and 35 patients in arm B were available for evaluation. There was no difference in patient activity, pathologic diagnosis, and differentiation or stage between the two arms. The median number of cycles was four in both arms. The response rate was 50% in arm A and 30% in arm B. The median survival times for arm A and B were 40 and 42 weeks, respectively, whereas the SDI was 1.94 and 1.7, respectively. More than grade III leukopenia was observed in 28.9% in arm A, which is more frequent than the 17.2% in arm B. There was a significant correlation between the SDIs and response rates and median survival (r2 = 0.629, p = 0.001; r2 = 0.453, p = 0.001, respectively). Although the follow-up period is relatively short, the survival time was similar in both arms. Because a high response rate may not be followed by a high survival time in combination chemotherapy of NSCLC, further studies on the appropriate dose of individual agents with regard to the relationship between response rate, severity, and incidence of toxicities and survival rate should be carried out.     

Carboplatin, ifosfamide, and vinorelbine in the treatment of advanced non-small-cell lung cancer: a phase II study

The authors evaluated the efficacy and toxicity of the combination of carboplatin, ifosfamide, and vinorelbine in the treatment of advanced non-small-cell lung cancer. From March 1994 through March 1996, 56 previously untreated patients with stage IIIB or stage IV non-small-cell lung cancer with measurable lesions and good performance status were entered in the study. The chemotherapy schedule was as follows: carboplatin 100 mg/m2 and ifosfamide 1,500 mg/m2 with mesna on days 1, 2, and 3; vinorelbine 25 mg/m2 on days 1 and 8, every 21 days; for a total of six courses. Among 55 evaluable patients there were three complete responses (5%) and 22 partial responses (40%), for a response rate of 45% (95% confidence interval, 32-59%). The median response duration was 10.3 months (range, 2.5-27.7 months), and median survival time was 11.3 months (range, 1.1-28.1 months). The survival rate at 1 year was 48%. Toxicity included hematologic toxicity in 60% of the 247 treatment cycles administered, nausea, alopecia, and neuropathy. One pathologic complete response was observed in a patient with stage IIIB disease who became operable after four courses of chemotherapy. The outpatient treatment with carboplatin, ifosfamide, and vinorelbine shows activity in advanced non-small-cell lung cancer. The toxicity was well tolerated by patients with a good performance status.     

Continuous-infusion vinorelbine for the treatment of advanced non-small-cell lung cancer: a phase I/II study

BACKGROUND: In this phase I/II trial, the maximum tolerated dose (MTD) and activity of vinorelbine administered in continuous infusion as first-line treatment for advanced non-small-cell lung cancer (NSCLC) was determined in 25 consecutive chemotherapy-naive patients with advanced NSCLC. PATIENTS AND METHODS: Vinorelbine was administered as an initial intravenous (I.V.) bolus of 8 mg/m(2) on day 1 followed by a 4-day continuous I.V. infusion at 5 different 24-hour dose levels to be repeated every 21 days. All 25 patients (159 cycles) were evaluable for response. The MTD was 8 mg/m(2) bolus followed by a continuous I.V. infusion of 11 mg/m(2) per day over 4 days. RESULTS: The dose-limiting toxicities were febrile neutropenia in 6 patients and grade 3 mucositis in 2 patients. There was less neurotoxicity and constipation and more mucositis compared with the weekly bolus scheme. There was no significant cumulative toxicity after 3 cycles. Treatment responses were observed in 6 patients: 1 complete response and 5 partial responses. The overall response rate was 24% (95% confidence interval [CI], 8%-40%). Median time to progression was 4 months (95% CI, 2-11 months), and median survival was 6 months (95% CI, 2-18 months). CONCLUSION: The results demonstrate that, in this setting of first-line treatment of NSCLC, vinorelbine administered as an 8 mg/m(2) bolus followed by a continuous infusion of 11 mg/m(2) per day over 4 days is the recommended schedule. Further trials are necessary to establish activity and possible benefits of combination with other agents.

Phase II study of sequential treatment of advanced non-small-cell lung cancer: three cycles of high-dose epirubicin plus cisplatin followed by weekly vinorelbine

Previous phase I, II, and III studies on high-dose epirubicin (HDEPI), alone or in combination with cisplatin (CP), indicate an interesting activity of this drug in the treatment of non-small-cell lung cancer (NSCLC). However, the toxicological profile of HDEPI limits its prolonged use. In our experience, vinorelbine (VNR) seems to be a suitable drug for long-term monotherapy for advanced NSCLC. On these grounds, advanced NSCLC patients were treated with the following strategy: 3 consecutive cycles of CP 60 mg/m2 and HDEPI 120 mg/m2 on day 1, every 3 weeks; then, irrespective of response, weekly VNR at a dose of 25 mg/m2 was administered at home. From December 1996 to March 1998, 25 patients entered the study. After receiving 3 cycles of CP/HDEPI, 8 patients (32%) had a partial response and 3 (12%) had a minor response. Nine patients had stable disease (36%) and 4 (16%) had progressive disease. Twenty-three patients received weekly VNR, and the median number of administrations was 10 (range, 1-38). After VNR treatment, we observed a partial response in 2 patients who previously had stable disease. Therefore, the overall response rate to sequential treatment was 40%; median time to progression was 7 months (range, 2-26 months). The major toxicities due to the CP/HDEPI regimen were neutropenia (72%) and alopecia (80%). During the VNR treatment, grade 3/4 neutropenia was seen in 36% of patients. The doses and the timing of VNR administrations were modified according to toxicity. Symptoms such as cough, dyspnea, and pain, present in 21 patients before the treatment, improved in 11 cases (52%). Median overall survival is 9 months (range, 3-40+ months); one patient is still alive after 40 months. One- and 2-year survival rates are, respectively, 44% and 16%. This study confirms the activity of CP/HDEPI in NSCLC and indicates that the sequential treatment of CP/HDEPI for 3 cycles followed by weekly VNR could be considered an effective strategy for locally advanced or metastatic NSCLC.     

Randomized phase II study of cetuximab plus cisplatin/vinorelbine compared with cisplatin/vinorelbine alone as first-line therapy in EGFR-expressing advanced non-small-cell lung cancer.

BACKGROUND: The Lung Cancer Cetuximab Study is an open-label, randomized phase II pilot study of cisplatin and vinorelbine combined with the epidermal growth factor receptor (EGFR)-targeted monoclonal antibody cetuximab versus cisplatin and vinorelbine alone, in patients with advanced EGFR-expressing, non-small-cell lung cancer (NSCLC). End points of the study are activity, safety and pharmacokinetics. PATIENTS AND METHODS: Following randomization, for a maximum of eight cycles, patients received three-weekly cycles of cisplatin (80 mg/m(2), day 1) and vinorelbine (25 mg/m(2) on days 1 and 8) alone or following cetuximab treatment (initial dose 400 mg/m(2), followed by 250 mg/m(2) weekly thereafter). RESULTS: Eighty-six patients were randomly allocated to the study (43 per arm). Confirmed response rates were 28% in the cisplatin/vinorelbine arm (A) and 35% in the cetuximab plus cisplatin/vinorelbine arm (B). Median progression-free survival (PFS) was 4.6 months in arm A and 5.0 months in arm B, with PFS rates at 12 months of 0% and 15%, respectively. Median survival was 7.3 months in arm A and 8.3 months in arm B. The 24-month survival rates were 0% and 16%, respectively. The cetuximab combination was well tolerated. CONCLUSION: In the first-line treatment of advanced NSCLC, the combination of cetuximab plus cisplatin/vinorelbine demonstrated an acceptable safety profile and the potential to improve activity over cisplatin/vinorelbine alone.     

Phase II study of a three-drug combination of ifosfamide, cisplatin and vindesine in non-small-cell lung cancer

Between February 1986 and April 1987, we conducted a phase II clinical trial of a three-drug combination of ifosfamide, cisplatin, and vindesine in advanced non-small-cell lung cancer. The combination consisted of ifosfamide, 1,300 mg/m2, on days 1 through 5, cisplatin, 20 mg/m2, on days 1 through 5, and vindesine, 3 mg/m2, on days 1 and 8. Courses were repeated at 4-week intervals until disease progression or unacceptable toxicity occurred. Of 21 patients evaluated, one had a complete response and 12 had partial response, with an overall response rate of 62%. The projected median response duration was 30 weeks. The median survival for all patients has not been reached: 14 of 21 patients are still alive with a median follow-up period of 41 weeks (range, 12 to 73 weeks). The major toxicity was myelosuppression. One patient died of septicemia while neutropenic, but the toxicity was well tolerated in the rest. These results indicate that this three-drug combination is active against non-small-cell lung cancer and warrants further clinical trials.     

Unfavorable therapeutic index of cisplatin/gemcitabine/vinorelbine in advanced non-small-cell lung cancer

In view of favorable reports with the 3-drug combination of PGV (cisplatin/gemcitabine/vinorelbine), this multicenter phase II study evaluated the therapeutic index of PGV in patients with advanced non-small-cell lung cancer (NSCLC). Thirty-two patients with stage IV NSCLC and 1 with stage IIIB were studied. There were 23 men and 10 women, with a median age of 63 years (range, 38-80 years). Twelve patients had a performance status (PS) of 0, and 21 patients had a PS of 1. Treatment consisted of cisplatin 50 mg/m2, gemcitabine 1000 mg/m2, and vinorelbine 25 mg/m2 all given intravenously on days 1 and 8, in 21-day cycles. Fifteen patients (45%; 95% confidence interval (CI), 28%-64%) achieved a partial response. Median response duration was 3 months (range, 1-9 months). The median and 1-year survival rates were 9.4 months and 39% (95% CI, 23%-58%), respectively. The median number of cycles was 4. Only 3 patients (9%) completed treatment without regimen modifications. Median dose intensity (% planned) was cisplatin 24 mg/m2/week (72%), gemcitabine 483 mg/m2/week (72%), and vinorelbine 12 mg/m2/week (72%). Toxicities were predominantly hematologic, with grade 3/4 neutropenia (67%), febrile neutropenia (21%), and thrombocytopenia (67%). There were 3 (9%) treatment-related deaths due to neutropenic complications. This study confirms the substantial antineoplastic activity of PGV. We observed a high rate of severe hematologic toxicity, especially febrile neutropenia, despite a lower delivered dose intensity of PGV. Given these results, PGV appears to offer no therapeutic advantage to current doublet regimens.     

Phase I/II investigation of paclitaxel, ifosfamide and carboplatin for advanced non-small-cell lung cancer.

BACKGROUND: The aim of this study was to evaluate feasibility and tolerability of the three-drug combination of paclitaxel, ifosfamide and carboplatin (TIC) in patients with advanced non-small-cell lung cancer. The specific objectives of the study were: (i) to define the dose-limiting toxicities (DLTs) and the maximum-tolerated dose of ifosfamide administered as part of the combination; and (ii) to determine the overall response rate and overall survival of patients treated with this regimen. PATIENTS AND METHODS: Patients with untreated, stage IIIB (pleural effusion) or stage IV non-small-cell lung cancer were enrolled in one of three cohorts. Patients received paclitaxel 200 mg/m(2) as a 1-h infusion on day 1 with carboplatin at an area under the concentration-time curve (AUC) of 6 mg.min/ml on day 2. For dose level I, ifosfamide was administered at a dose of 2 g/m(2) on days 1 and 2. For dose levels II and III, the dose of ifosfamide was decreased to 1.5 g/m(2) on days 1 and 2 and the dose of carboplatin was decreased to AUC 5 mg.ml/min. Therapy for dose levels I and III included filgrastim support (5 micro g/kg/day), which was initiated on day 3 and continued until after day 11 or until an absolute neutrophil count >10 000/ micro l. Treatment cycles were repeated every 21 days. Once the phase II dose was established, a full cohort of patients received therapy at this dose level to examine further the regimen's activity and tolerability. RESULTS: Neutropenia was the DLT encountered for dose levels I and II. No DLT was encountered in the initial six patients treated at dose level III, and therefore this dose level was declared the recommended phase II dose. A total of 49 patients were treated at the recommended phase II dose. The predominant non-hematological toxicity encountered with this triplet regimen was cumulative peripheral neuropathy. Of the 65 eligible patients enrolled in this study, 17 (26%) responded. There were 15 patients with partial responses (23%), two with regression, and 26 with stabilization of disease (40%). Median progression-free and overall survival were 4.8 and 9.4 months, respectively. CONCLUSIONS: The combination TIC is well-tolerated. This triplet regimen produced response and survival rates in advanced non-small-cell lung cancer similar to those of other current combination chemotherapy regimens.     

Tirapazamine with cisplatin and vinorelbine in patients with advanced non-small-cell lung cancer: a phase I/II study

This phase I/II study was conducted to evaluate the safety and efficacy of tirapazamine in combination with cisplatin and vinorelbine for patients with advanced-stage IIIB/IV chemonaive non-small-cell lung cancer. Seventy patients with a Karnofsky performance status of > or = 60% were included. In the phase I part of the study, 21 patients were treated on day 1 with tirapazamine (escalating doses of 260, 330, or 390 mg/m(2)), cisplatin (75 or 100 mg/m(2)), and vinorelbine (25 or 30 mg/m(2)) for a maximum of 6 cycles every 4 weeks. Vinorelbine was repeated every week. In the phase II part of the study, 49 patients were treated on day 1 with tirapazamine 390 mg/m(2), cisplatin 100 mg/m(2), and vinorelbine 30 mg/m(2). The maximum tolerated dose was not reached. Muscle cramps, vomiting, nausea, tinnitus, neutropenia, and diarrhea were the most frequently reported adverse events in the phase I part of the study. Most of these events were grade 1 or 2. In the phase II part of the study, response rate was 47%, and median survival was 50 weeks. The most frequently reported adverse event was neutropenia. Asthenia, fever, anemia, vomiting, weight decrease, nausea, and muscle cramps were also noted. For patients treated at the maximum dose, dose reductions occurred 14% of tirapazamine cycles and in 4% of cisplatin cycles. The median number of cycles was 3. This regimen has a manageable toxicity profile. Response rate and median survival suggest that this combination might be more active than the cisplatin/vinorelbine combination. This triplet is currently being evaluated in a phase III study.     

Phase II study with gemcitabine, ifosfamide and cisplatin in advanced non-small cell lung cancer

The aim of the present study was to determine the clinical activity and toxicity of a novel chemotherapy combination regimen of gemcitabine, ifosfamide and cisplatin (GIP), administered every 3 weeks, in patients with inoperable non-small cell lung cancer (NSCLC). From October 1998 to July 1999, 18 previously untreated stages IIIb (4) and IV (14) patients were enrolled into the study. Gemcitabine and ifosfamide (with mesna as uroprotection) was administered on days 1 and 6, at a dose of 1000 and 1500 mg/m², respectively; and cisplatin was given on day 1 at a dose of 60 mg/m², every 3 weeks. All 18 patients were evaluable for response and toxicity profiles. One patient achieved a complete response, and 11 patients achieved a partial response, with an overall response rate of 66.7% (95% CI, 45–89%). The main toxicity was hematological, a NCI grade 3–4 neutropenia in 16 patients (88.9%) during the treatment course. Febrile neutropenia occurred in three patients (16.6%). Grade 3 anemia occurred in eight patients (44.4%) and grade 3–4 thrombocytopenia occurred in 11 patients (61.1%). Non-hematological toxicity was mild and tolerable. No toxic death occurred. The median survival was 12.7 months and 1 year survival was 58.4%. The GIP combination chemotherapy produced a high response rate in advanced NSCLC; however, there was a relatively high percentage of hematological toxicity that still could be tolerated. A randomized trial comparing GIP to a two-drug combination of gemcitabine and cisplatin is planned.

Phase I study of ifosfamide plus high-dose epirubicin in advanced non-small-cell lung cancer

 The present phase I study was designed to determine the maximum tolerated dose (MTD) of epirubicin given in combination with ifosfamide at a dose of 3 g/m², recycled every 4 weeks, in patients with advanced non-small-cell lung cancer (NSCLC). A total of 18 patients entered the study; they received the following four dose levels of epirubicin (i. v., day 1): 75 (6 patients), 90 (3 patients), 105 (3 patients), and 120 mg/m² (6 patients). The MTD of epirubicin was 120 mg/m², neutropenia being the dose-limiting toxicity. We observed 1/6, 1/3 1/3, and 2/6 partial responses (PRs) at epirubicin dose levels of 75, 90, 104, and 120 mg/m², respectively. A phase II study of epirubicin given at a dose of 120 mg/m² in association with conventional-dose ifosfamide in advanced NSCLC is in order. Received: 27 March 1995 / Accepted: 14 September 1995     

Phase I/II study of vinorelbine, mitomycin, and cisplatin for stage IIIB or IV non-small-cell lung cancer.

PURPOSE: To determine the maximum-tolerated doses (MTDs) of vinorelbine (VRB), mitomycin (MMC), and cisplatin (P), given in two courses every 28 days to previously untreated patients with stage IIIB or IV non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: At least three or four patients were entered at each dose level. The starting dose was 20 mg/m(2) for VRB on days 1 and 8 and 4 mg/m(2) for MMC on day 1, with a fixed dose of P 80 mg/m(2) on day 1 every 4 weeks. MMC was increased to 6 mg/m(2) at dose level 2 and subsequently to 8 mg/m(2) at dose level 4. At dose level 3, VRB was increased to 25 mg/m(2). Twenty-five patients were entered onto the phase I study and 19 patients were entered onto phase II study. RESULTS: Nadir leukocyte and platelet counts decreased at each dose level. At dose levels 1 and 2, the dose-limiting toxicity (DLT) was not seen, but at dose levels 3 and 4, DLT was encountered in two patients. Nearly half the patients at dose level 4 had dose reduction due to grade 4 leukopenia. A mathematic model of all toxicity suggested that dose level 4 (VRB 25 mg/m(2) on days 1 and 8 and MMC 8 mg/m(2) and P 80 mg/m(2) on day 1, every 4 weeks) would be the recommended dose for phase II study at which grade 4 toxicity is expected in 相似文献   

Biweekly regimen of cisplatin, gemcitabine and vinorelbine for advanced non-small-cell lung cancer

Purpose: Improving chemotherapeutic efficacy in non-small cell lung cancer (NSCLC) will require the development of new strategies to better use currently available agents. To assess the efficacy and safety of a biweekly regimen of cisplatin, gemcitabine and vinorelbine for advanced non-small-cell lung cancer. Methods: Patients with selected stage IIIb (pleural effusion)/stage IV NSCLC, performance status of 0–2 and normal organ function were eligible. Treatment consisted of cisplatin 100 mg/m² on day 1 plus gemcitabine, 1,000 mg/m² and vinorelbine 25 mg/m² on days 1 and 15 every 28 days. Results: Of the 40 patients enrolled and assessable for response, there were five (12.5%) with confirmed complete response and 14 (35%) with a confirmed partial response for an overall response rate of 47.5%. Nine patients had stable disease while 12 (30%) progressed. Median progression-free survival and overall survival for all patients were 6.3 and 11.1 months, respectively. Toxicity was principally hematologic, with grade 3–4 neutropenia in 30%, and grade 3–4 nausea/vomiting in 22.5%. There were no treatment-related deaths. Conclusions: The biweekly regimen of cisplatin, gemcitabine and vinorelbine is associated with a high rate of response, lesser toxicity than other three-drug regimens and no benefit of survival. Therefore, the regimen under study may be an appealing alternative when considering other treatment modalities for advanced lung cancer, such as neoadjuvant therapy.     

Phase II study of carboplatin,cisplatin, and vindesine in advanced non-small-cell lung cancer

Cisplatin in combination with vindesine has been widely used for the treatment of advanced non-small-cell lung cancer (NSCLC), producing an overall response rate of 32%. We conducted a phase II study to examine whether the addition of carboplatin to the combination of cisplatin and vindesine would improve the antitumor activity of the two platinum agents in advanced NSCLC without increasing their toxicity. Carboplatin (240 mg/m²) and vindesine (3 mg/m²) were given intravenously on day 1 and cisplatin (60 mg/m²) and vindesine (3 mg/m²), on day 8. Of the 40 evaluable patients with advanced NSCLC, 12 showed a partial response, for an overall response rate of 30% (95% confidence interval, 17%–47%). The median duration of response was 12 weeks, and the median survival duration for all patients was 38 weeks. The major toxicity was hematologic: leukopenia (WHO grade3) was observed in 21 patients (53%) and anemia (WHO grade3), in 13 patients (33%). However, thrombocytopenia was mild and WHO grade 3 toxicity was observed in only 4 patients (10%). Nonhematologic toxicities consisted mainly of WHO grade2 nausea and vomiting in 16 patients (40%) and WHO grade2 alopecia in 11 patients (28%). No significant nephrotoxicity or neurotoxicity was seen. Our findings indicate that the addition of carboplatin to the combination of cisplatin and vindesine does not improve antitumor activity in patients with advanced NSCLC.     

Phase II study of irinotecan plus cisplatin in patients with advanced non-small-cell lung cancer.

PURPOSE: To evaluate the antitumor efficacy and safety of a combination of irinotecan (CPT-11) and cisplatin in patients with inoperable non-small-cell lung cancer (NSCLC). A secondary objective was to characterize the pharmacokinetics and pharmacodynamics of CPT-11 and its active metabolite, SN-38. PATIENTS AND METHODS: Patients with stage IIIB or IV NSCLC were treated with repeated 4-week courses comprising CPT-11 (60 mg/m(2)) administered on days 1, 8, and 15, and a single dose of cisplatin (80 mg/m(2)) after CPT-11 administration on day 1. RESULTS: Fifty-two patients were enrolled, including 33 men and 19 women. The median age was 61 years (range, 29 to 79 years). Southwest Oncology Group performance status was 0 in 12 patients, 1 in 32 patients, and 2 in eight patients. Eleven and 41 patients had stage IIIB and IV disease, respectively. Objective responses occurred in 28.8% of patients (15 of 52; 95% confidence interval, 16.5% to 41.2%). The median survival duration was 9.9 months (range, 1.6 to 30.8 months). The 1-year survival rate was 37%. Grade 3/4 adverse events consisted primarily of nausea (32. 7% ) or vomiting (13.5%), late-onset diarrhea (17.3%), and neutropenia (46.1%). The study design led to preferential modification of CPT-11 doses, resulting in CPT-11 dose attenuations to < or = 40 mg/m(2) in the majority of patients (31 of 52; 60%), whereas dose reductions of cisplatin were uncommon. CPT-11 pharmacokinetic parameters were comparable to those reported previously in single-agent studies. CONCLUSION: CPT-11/cisplatin is an active combination regimen with manageable toxicity in the therapy of stage IIIB/IV NSCLC. Future studies should be designed with schedules and dose modification provisions that avoid unnecessary CPT-11 dose reductions to exploit more directly the therapeutic synergy of these agents.     

Phase I/II study of cisplatin combined with weekly paclitaxel in patients with advanced non-small-cell lung cancer

To determine the maximum-tolerated dose (MTD) and the recommended dose (RD) of paclitaxel administered weekly with a fixed dose of cisplatin, and to assess the toxicity and activity of this combination, we conducted a phase I/II trial in patients with advanced non-small-cell lung cancer (NSCLC). In this study, patients with stage IIIB/IV NSCLC were eligible. Paclitaxel, at a starting dose of 40 mg x m(-2) week(-1) on days 1, 8, and 15, was combined with a fixed dose of cisplatin 80 mg x m(-2) on day 1. Chemotherapy was given in a 4-week cycle. In this phase I/II study, 38 patients were enrolled. Dose-limiting toxicities (DLT) were neutropenia, fatigue, and omission of treatment due to leucopenia, thrombocytopenia, or febrile neutropenia. The MTD and RD were estimated to be 70 mg x m(-2). Of the 37 assessable patients, 23 had a partial response and one had a complete response. Overall response rate was 62.1% (95% confidence interval (CI): 46.5-77.7%). The progression-free survival, the median survival time, and the 1-year survival rate were 5.5 months, 13.7 months, and 56.9%, respectively. This regimen is tolerable and very active against advanced NSCLC, and its efficacy should be confirmed in a phase III study.     

奥沙利铂加长春瑞滨与顺铂加长春瑞滨治疗晚期非小细胞肺癌的随机对照研究

目的探索奥沙利铂＋长春瑞滨（NL方案）与顺铂＋长春瑞滨（NP方案）治疗晚期非小细胞肺癌（NSCLC）的疗效、不良反应及患者的生活质量。方法可评价疗效的NSCLC患者以2：1比例随机分入治疗组与对照组。治疗组70例,化疗方案为长春瑞滨25mg／m^2静脉冲入,第1。8天;奥沙利铂130mg／m^2静脉滴注,第2天;21d为1个周期。对照组32例,化疗方案为顺铂80mg／m^2静脉滴注,分2—3d给予;长春瑞滨用法同治疗组。结果治疗组与对照组的有效率分别为35．7％和43．8％（P=0．4）,中位肿瘤进展时间分别为4．7个月和5．5个月（P=0．6）,1年生存率分别为38．5％和58．6％（P=0．07）。治疗组Ⅰ-Ⅱ度感觉异常发生率为68．4％,显著高于对照组的36．4％（P：0．0017）;而治疗组I一Ⅱ度粒细胞减少率为49．4％,显著低于对照组的70．6％（P：0．037）。两组患者各项生活质量评分差异无统计学意义。结论奥沙利铂＋长春瑞滨治疗晚期NSCLC疗效确切,患者耐受性良好,为晚期NSCLC的治疗提供了一种新的选择。
