BACKGROUND: Second-line chemotherapy with docetaxel improves survival and quality of life (QoL) in patients with nonsmall cell lung carcinoma (NSCLC) who fail first-line platinum-based regimens. The authors sought to determine the activity of second-line, low-dose, weekly paclitaxel in patients with NSCLC who failed first-line chemotherapy with carboplatin plus paclitaxel. METHODS: Patients with Stage IIIB/IV NSCLC who had received first-line carboplatin/paclitaxel were treated with low-dose (80 mg/m(2)), weekly paclitaxel at the time of disease progression. Response rates, QoL, and survival were outcome end points. RESULTS: Sixty-two patients were included in this analysis. The median age was 62 years (range, 32-76 years), 55% of patients were male, 89% of patients had Stage IV NSCLC, and the Karnofsky performance status was 90-100% in 31% of patients, 70-80% in 55% of patients, and 60% in 14% of patients. Twenty-six percent of patients experienced disease progression as their best response to first-line carboplatin plus paclitaxel, whereas 52% of patients had stable disease, and 23% of patients had achieved a response. The median time from first-line carboplatin plus paclitaxel to second-line, low-dose, weekly paclitaxel was 9.5 weeks (range, 1-78 weeks). The toxicity profile was extremely favorable, with no Grade 4 toxicity and < 10% Grade 3 hematologic or nonhematologic toxicity in all patients with the exception of neuropathy. Ten percent of patients experienced both Grade 2 and Grade 3 neuropathy. The overall objective response rate was 8%. The median survival was 5.2 months (95% confidence interval [95%CI], 3.6-6.2 months), and the 1-year and 2-year survival rates were 20% (95%CI, 10-30%) and 9% (95%CI, 1-16%), respectively. CONCLUSIONS: Second-line, low-dose, weekly paclitaxel had activity in selected patients with Stage IIIB/IV NSCLC who failed first-line chemotherapy with carboplatin plus paclitaxel. The toxicity profile of this approach is extremely favorable, and outcome expectations are similar to the outcome expectations with other single agents in this setting. 相似文献

BACKGROUND: The purpose of the current study was to evaluate the efficacy and tolerance of the noncisplatin-based combination of paclitaxel and gemcitabine administered weekly for patients with untreated metastatic nonsmall cell lung cancer (NSCLC). METHODS: Patients with Stage IIIB/IV or recurrent NSCLC, a performance status of 0-2, and no prior chemotherapy exposure were eligible. Patients received gemcitabine 1000 mg/m2 and paclitaxel 85 mg/m2 on Days 1, 8, 15, 22, 29, 36 of an 8-week cycle until progression. RESULTS: Thirty-nine eligible patients were enrolled. The median age was 66 years and 14 patients were > or =70 years old. Performance status was 2 in 13 (33%) and 29 patients (75%) had Stage IV. Five patients (12.8%) developed interstitial pneumonitis and 2 of these were responsive to steroid therapy. The overall response rate was 23.1%, with no complete responses. The median survival was 32 weeks and the 1-year survival was 32%. CONCLUSIONS: This regimen of weekly paclitaxel and gemcitabine has modest activity in advanced NSCLC. 相似文献

Purpose Irinotecan, a topoisomerase I inhibitor, is an effective agent for non-small-cell lung cancer (NSCLC). To determine the efficacy and toxicity of irinotecan and carboplatin, we conducted a phase II study in 61 patients with advanced NSCLC.Methods Every 4 weeks, the patients received irinotecan 50 mg/m2 (days 1, 8 and 15) and carboplatin (day 1) with a target AUC of 5 mg min/ml using the Chatelut formula.Results All patients were evaluable for toxicity, and of 59 patients evaluable for response, 20 achieved a partial response and 26 showed no change. The overall response rate was 34% (95% confidence interval 23–48%). Grade 3 or 4 anemia, leukopenia, neutropenia, thrombocytopenia and diarrhea occurred in 32%, 32%, 60%, 25%, and 7%, respectively. The median survival time and 1-year, and 2-year survival rates were 10.0 months, 37.6%, and 15.2%, respectively.Conclusions Irinotecan with carboplatin is effective for advanced NSCLC and safe. 相似文献

To determine the efficacy and toxicity of irinotecan combined with carboplatin, we conducted a phase II trial. Eligibility criteria were: chemotherapy-naïve, small-cell lung cancer (SCLC), good performance status (PS: 0–2), age⩽75 years, and adequate organ function. The patients'' characteristics were: male/female=56/5; PS 0/1/2=19/38/4; median age (range)=68 years(51–75 years); limited disease (LD)/extensive disease (ED)=27/34. The patients received irinotecan (50 mg m−2) on days 1, 8, and 15, and carboplatin (AUC 5, Chatelut formula) on day 1 every 4 weeks. In total, 61 patients were eligible and all were evaluated. In all, 31 patients were treated with four or more courses of chemotherapy. Of the patients, 17 showed a complete response (CR), 34 showed a partial response (PR), nine had stable disease (SD), and one had progressive disease (PD). The overall response rate was 84% (95% confidence interval (CI), 72–91%; LD 89%, ED 79%) and the CR rate was 28% (95%CI, 17–41%; LD 37%, ED 21%). The median time to tumour progression was 6.1 (LD 6.4, ED 5.4) months. The medial survival time was 15.0 (LD 20.0, ED 9.7) months, and the 2-year and 5-year survival rates were 31.1% (LD 48.1%, ED 17.7%) and 9.5% (LD 11.1%, ED 5.9%), respectively. Grade 3 or 4 leucopenia, neutropenia, thrombocytopenia, anaemia, and diarrhoea occurred in 33, 74, 41, 39, and 13% of cases, respectively. In conclusion, the combination of irinotecan and carboplatin is an active and well-tolerated regimen in cases of SCLC. 相似文献

The purpose of this phase II trial was to evaluate the efficacy and toxicity of carboplatin plus paclitaxel in the treatment of advanced non-small cell lung cancer (NSCLC) previously treated with chemotherapy. Patients with a performance status (PS) of 0 or 1 who had received one or two previous chemotherapy regimens for advanced NSCLC were eligible. Paclitaxel 200mg/m(2) was infused over 3h and followed by carboplatin (area under the curve 6) infusion over 1h, once every 3 weeks. Thirty patients were enrolled. A complete response was observed in 1 patient and a partial response in 10 patients, for an overall response rate of 36.7%. The median time to progression was 5.3 months. The median survival time was 9.9 months, and the 1-year survival rate was 47%. Hematological toxicity in the form of grade 3/4 neutropenia occurred in 54%, but grade 3 febrile neutropenia developed in only 3%. Non-hematological grade 3 toxicities were less frequent. There were no treatment-related deaths. The combination of carboplatin plus paclitaxel is an active and well-tolerated regimen for the treatment of NSCLC patients who have previously been treated with chemotherapy and have a good PS. 相似文献

BACKGROUND: The combination of paclitaxel and carboplatin is widely used in the treatment of patients with advanced nonsmall cell lung carcinoma. In this Phase I/II study the authors evaluated the feasibility, toxicity, and efficacy of adding a third active antineoplastic agent, gemcitabine, to the paclitaxel/carboplatin combination for the treatment of patients with advanced nonsmall cell lung carcinoma. METHODS: Patients with advanced (AJCC Stage IIIB or IV) nonsmall cell lung carcinoma previously untreated with chemotherapy were eligible for this trial. The maximum tolerated doses, determined in the Phase I trial and subsequently used in the Phase II trial, were: paclitaxel, 200 mg/m2, as a 1-hour infusion on Day 1; carboplatin, at area under the curve dose of 5.0 intravenously (i.v.), on Day 1; and gemcitabine, 1000 mg/m2 i.v., on Days 1 and 8. Treatment courses were repeated every 21 days. The Phase II study was conducted in 13 community-based practices in the Minnie Pearl Cancer Research Network; 77 patients were treated between December 1996 and September 1997. RESULTS: Thirty-four of 77 patients (44%) in the Phase II trial had major responses (partial responses, 32 patients and complete responses, 2 patients). An additional 25 patients (33%) had stable disease or minor response; only 23% of patients progressed or were removed from study at or prior to first reevaluation. The median survival was 9.4 months, with a 45% actuarial 1-year survival rate. Myelosuppression was the most common toxicity, with Grade 3/4 NCI Common Toxicity Criteria leukopenia and thrombocytopenia in 49% and 45% of patients, respectively. However, only 11 patients (14%) required hospitalization for neutropenia/ fever, and none had bleeding complications. Grade 3/4 nonhematologic toxicities included fatigue (41%), arthralgias/myalgias (26%), peripheral neuropathy (8%), nausea/emesis (6%), and hypersensitivity reactions (4%). There was one treatment-related death due to sepsis. CONCLUSIONS: This three-drug regimen is active and has acceptable toxicity in patients with advanced nonsmall cell lung carcinoma. Myelosuppression, particularly thrombocytopenia, is increased in comparison to the paclitaxel/carboplatin regimen. Fatigue also may be increased, but other nonhematologic toxicities are not altered substantially by adding gemcitabine. Although the response rate and median survival are improved modestly compared with our previous experience with paclitaxel/carboplatin, definitive conclusions regarding the efficacy of this regimen await the completion of randomized trials. 相似文献

INTRODUCTION: This phase II study was designed to assess the activity and tolerability of the carboplatin-paclitaxel combination, given without routine growth factor support to previously untreated patients with stage IIIB and IV non-small cell lung cancer. PATIENTS AND METHODS: Sixty patients (15 stage IIIb and 45 stage IV) received paclitaxel 225 mg/ml on day 1, followed by carboplatin AUC 6 mg/ml per minute (Calvert formula) every 3 weeks. Paclitaxel was administered as a 3-h intravenous infusion followed by carboplatin over 30 min, on completion of paclitaxel administration. RESULTS: The combination showed a good safety profile with Grade 4 neutropenia occurring in 31% of patients without any serious infectious episodes requiring hospitalization. Moderate to severe anemia and thrombocytopenia seldom occurred. Sensorimotor peripheral neuropathy (Grade 2-3) and myalgia (Grade 3-4) were documented in 34 and 20% of the patients, respectively. Among 59 evaluable patients, there was one complete response and 26 partial responses for an overall response rate of 46% (95% C.I.: 34-59%). With a minimum follow-up duration of 16.5 months, the median overall survival time is 52 weeks and the 1-year survival rate is 50%. Median duration of response is 20 weeks (range: 4-52) and progression-free survival is 22 weeks (range: 5-77). CONCLUSION: In advanced NSCLC, the combination carboplatin-paclitaxel at doses of AUC 6 mg/ml per minute and 225 mg/ml every 3 weeks, is both active and relatively well-tolerated. 相似文献

Background. This trial was conducted to determine the maximum tolerated dose (MTD) and principal toxicities of combinations of docetaxel
and carboplatin administered every 3 weeks to patients with advanced non-small-cell lung cancer (NSCLC) previously untreated
with chemotherapy, and to find suitable doses for phase II studies in Japanese subjects.
Methods. Japanese patients with advanced NSCLC and performance status 0 to 2 according to the World Health Organization classification,
but previously untreated with chemotherapy received docetaxel followed by carboplatin, each infused over a 1-h period. The
carboplatin dose was based on the target area under the curve (AUC), using Calvert's formula. Dose levels studied were: docetaxel
(mg/m2)/carboplatin AUC (mg/ml·min), 50/4, 60/4, and 60/5, repeated every 3 weeks. Granulocyte-colony stimulating factor (G-CSF)
support was first used when dose-limiting toxicities (DLTs) were encountered.
Results. Of 14 patients entered, 12 were assessable for toxicity and response. The MTD schedule was: docetaxel, 60 mg/m2, with carboplatin, AUC 5 mg/ml·min (DLTs in 3 of 3 patients). The recommended dosage was: docetaxel, 60 mg/m2, with carboplatin, AUC 4 mg/ml·min (DLTs in 2 of 6 patients). The main toxic effect was neutropenia, and any nonhematologic
toxic effects were mild. No thrombocytopenia occurred. Six of the 12 patients (50%) showed responses; 4 of the 6 at the recommended
doses.
Conclusion. Docetaxel 60 mg/m2, given over a 1-h period, followed by carboplatin, AUC 4 mg/ml·min, given over a 1-h period, is recommended for phase II
studies in Japan. This combined chemotherapy has mild toxicity, except for neutropenia, and is useful and easy to administer.
We therefore believe that phase II and phase III studies of this therapy would be well justified.

BACKGROUND: Multiple trials have been performed to evaluate second-line clinical chemotherapy in patients with advanced nonsmall cell lung carcinoma (NSCLC). However, no single agent or combination has demonstrated superior activity. METHODS: Patients with advanced NSCLC who had already received one chemotherapeutic regimen were treated with topotecan (0.75 mg/m(2) over 30 minutes, Days 1-5) and gemcitabine (400 mg/m(2) over 30 minutes, Days 1 and 5) every 21 days. RESULTS: Of 35 patients who were treated, 4 (11%) achieved a partial responses and 8 (23%) hadstable disease for at least four courses of treatment. The response rate for patients with refractory disease (progressing during frontline chemotherapy) was 18% (3 of 17) with 18% having stable disease for at least four courses of treatment. The median survival of the entire group was 7 months (range, 1.5-44 months) and 20% (7 of 35) of patients were alive 1 year from the initiation of topotecan and gemcitabine treatment. Patients with refractory disease had a median survival of 4(1/2) months, with 6-month and 1-year survival rates of 47% and 18%, respectively. During Course 1, five patients (14%) developed Grade IV neutropenia and three patients (9%) developed Grade IV thrombocytopenia. Nonhematologic toxicity was relatively mild, with one patient developing Grade III side effects (fatigue) and eight patients (23%) developing Grade II nonhematologic side effects. CONCLUSIONS: The combination of topotecan and gemcitabine demonstrated antitumor activity with a modest side effect profile in patients with advanced, previously treated NSCLC. 相似文献

PURPOSE: Irinotecan plus cisplatin has been previously documented to be effective in the treatment of extensive-disease small cell lung cancer (ED-SCLC). This study was undertaken to investigate the efficacy and feasibility of combination chemotherapy of irinotecan and carboplatin in previously untreated ED-SCLC. PATIENTS AND METHODS: From December 2002 to October 2005, 39 patients with previously untreated ED-SCLC were enrolled. Patients were treated with irinotecan (50mg/m(2) IV on days 1, 8, and 15) and carboplatin (target AUC=5 IV on day 1) every 4 weeks for up to six cycles. RESULTS: Thirty-four patients (87.2%) were male and the median age was 65 years. ECOG performance status was 0-1 in 20 (51.3%) patients and 2 in 19 (48.7%) patients. The median number of chemotherapy cycles was six (range: 1-6 cycles). Thirty-five patients were assessable for response evaluation. The overall response rate was 69.2% (1 CR, 26 PR) under the intent-to-treat analysis. After a median follow-up of 22.7 months, the median time to progression was 6.4 months (95% confidence interval [CI]: 5.7-7.1 months) and median overall survival was 11.0 months (95% CI: 9.9-12.0 months). The estimated 1-year survival rate was 42.5%. In terms of toxicities, Grade 3/4 neutropenia and thrombocytopenia occurred in eight (25.6%) and five (15.4%) patients, respectively. Grade 3/4 non-hematologic toxicities included diarrhea (10.3%), anorexia (7.7%), infection (10.3%), and neutropenic fever (12.8%). There was one treatment-related death due to superimposed infection on the broncho-pleural fistula. CONCLUSION: The combination chemotherapy of irinotecan and carboplatin was effective and tolerable in previously untreated ED-SCLC patients. 相似文献

BACKGROUND: The optimal treatment strategy for elderly patients with advanced nonsmall cell lung carcinoma has not been defined to date. The authors performed a retrospective analysis of a Phase III trial that treated patients who had Stage IIIB or IV nonsmall cell lung carcinoma with carboplatin and paclitaxel and analyzed the impact of age on response rate, survival, toxicity, and quality of life. METHODS: Patients with Stage IIIB or IV NSCLC were randomized to receive either 4 cycles of carboplatin at an area under the curve (AUC) of 6 and paclitaxel at a dose of 200 mg/m(2) every 21 days or treatment with carboplatin and paclitaxel (C/P) until they developed disease progression. At the time of disease progression, all patients on both arms were to receive second-line weekly paclitaxel at a dose of 80 mg/m(2) per week. In this analysis, patients age 70 years and older were compared with patients younger than age 70 years. In addition, a minimum log rank P value analysis was performed in an attempt to identify other potential age splits that may have been significant. RESULTS: Two hundred thirty patients were randomized. Sixty-seven patients were age 70 years or older (29%). The median number of cycles delivered for both age groups was 4 cycles (range, 0-19 cycles). No statistically significant differences in any of the most common toxicities (Grade >or= 2) associated with C/P were identified (data from Cycles 1-4) for patients younger than age 70 years compared with patients age 70 years and older, respectively, including neutropenia (38% vs. 35%), neuropathy (13% vs. 16%), leukopenia (7% vs. 13%), myalgia/arthralgia (15% vs. 9%), malaise (8% vs. 15%), anemia (9% vs. 4%), thrombocytopenia (7% vs. 9%), anorexia (8% vs. 4%), and nausea/emesis (14% vs. 15%). In addition, no potential age splits that may have been significant were found using a minimum log rank P value analysis. CONCLUSIONS: The current analysis demonstrated that C/P exhibited similar toxicity profiles in patients age 70 years and older compared with patients younger than age 70 years. The survival rates were not different between the two age groups, and there was no difference in progression of quality-of-life outcomes. In fit, elderly patients, C/P represented a reasonable standard regimen. 相似文献

OBJECTIVE: New effective therapy is desirable for outpatients with advanced non-small-cell lung cancer (NSCLC). Fractionated administration of paclitaxel may be less toxic and more active against NSCLC. The aim of this study was to evaluate the activity and toxicity of weekly paclitaxel therapy for chemotherapy-naive NSCLC. METHODS: Patients with pathological or cytological diagnosis of NSCLC, measurable lesions, and no prior therapy were enrolled. We administered weekly infusions of 80 mg/m(2) paclitaxel 3 times in a 4-week cycle. In the absence of progressive disease or intolerable toxicity, we treated each patient for a minimum of four cycles. RESULTS: Of 35 patients enrolled, 17 patients achieved partial response, although no complete responses were observed (response rate 49%; 95% confidence interval 32-66%). The median survival time was 55 weeks (range 6-93 weeks). Grade 3 or 4 leukopenia occurred in only 1 patient (3%). Neurotoxicity was the most frequent adverse effect (grades 1 and 2, 26 and 3%, respectively). Serious toxicity, observed in 2 patients (6%), was interstitial pneumonia, and 1 patient died from sequela. CONCLUSION: Low-dose weekly paclitaxel is a promising therapy for advanced NSCLC with high effectiveness and low toxicity. 相似文献

INTRODUCTION: To conduct a phase II study evaluating the efficacy of rationally sequenced paclitaxel, gemcitabine, and carboplatin in patients with stage IV or select stage IIIB non-small cell lung cancer (NSCLC). METHODS: Patients with select stages IIIB (pleural effusion) and IV NSCLC with an ECOG performance status of 0-1 and no prior chemotherapy for their disease were eligible to participate. Treatment was delivered as follows: paclitaxel at 70 mg/m2 followed by gemcitabine at 300 mg/m2 on day 1, with carboplatin (AUC 5) on day 2 of a 28-day cycle. Response was assessed after every two cycles of therapy. The primary endpoint of this trial was response rate, with secondary endpoints of time to progression and 1 year overall survival. RESULTS: Twenty patients were enrolled on protocol, one of whom never received chemotherapy. The median number of cycles delivered was 3 (range 0-8). A partial response rate of 42% (8/19; 95% CI: 20-67%) and a stable disease rate of 11% (2/19; 95% CI: 1-33%) were observed. The median overall survival time was 9.6 months (95% CI: 4.6-16.6), with a 1 year overall survival rate of 42.1% (95% CI: 24.9-71.3%). Eight patients (42%) stopped treatment due to toxicity. CONCLUSION: Paclitaxel followed by gemcitabine and then carboplatin is an active, albeit complex, regimen in the treatment of patients with advanced NSCLC with insufficient advantage to justify continuation of this regimen. 相似文献

Paclitaxel and carboplatin is widely used in the treatment of patients with advanced non-small cell lung cancer (NSCLC); however, median survival remains < 1 year. One strategy to improve survival is to add a third active drug with a differing mechanism of action. Gemcitabine is a novel antimetabolite with considerable activity in NSCLC. The primary objective of this Phase I/II study was to determine the maximally tolerated dose of gemcitabine administered with fixed doses of paclitaxel and carboplatin in untreated patients with advanced NSCLC. 相似文献

BACKGROUND: Trastuzumab is a monoclonal antibody directed against the human epidermal growth factor receptor-2 (HER-2). Nonsmall cell lung carcinoma (NSCLC) overexpresses HER-2 protein in approximately 20% of cases. In the current study, the authors combined trastuzumab with weekly taxanes in an attempt to improve outcomes over standard chemotherapy in patients with advanced NSCLC. METHODS: The primary objective was to determine whether docetaxel plus trastuzumab or paclitaxel plus trastuzumab was the superior regimen based on response and toxicity, and to determine whether either regimen was appropriate for further testing in a randomized Phase III trial. After stratification based on the results of HER-2 immunohistochemistry, chemotherapy-naive patients were randomized to receive trastuzumab plus docetaxel or trastuzumab plus paclitaxel. The study was designed so patients with or without HER-2 overexpression would be distributed equally between the study arms. RESULTS: Immunohistochemistry for HER-2 protein expression was attempted for 182 pathologic samples from 169 patients. Twenty-eight of the 179 evaluable samples (16%) revealed 2+ or 3+ staining. The objective response rate was 23% (7 of 30 patients) in the patients treated with docetaxel plus trastuzumab and 32% (11 of 34 patients) in the patients treated with paclitaxel plus trastuzumab (P=0.76, Wilcoxon test). No difference was noted in the median survival (16 mos vs. 14 mos) or 1-year survival (57% vs. 55%) (P=0.998). Toxicities were mild in both treatment arms. No difference with regard to response rates or survival was noted between HER-2-positive (2+ or 3+) and HER-2-negative (0-1+) patients. CONCLUSIONS: The expression of HER-2 protein in patients with advanced NSCLC in this study was found to be similar to that reported in previous series. The response rates and toxicities for patients treated with docetaxel and trasuzumab or paclitaxel and trasuzumab were not significantly different, though survival in both arms was better than expected. HER-2 expression status did not appear to affect outcomes for this uniform group of patients who were treated in a comparable fashion. Because of the infrequency of HER-2 overexpression, and the absence of improved outcomes in patients with NSCLC who were treated with trastuzumab plus chemotherapy in other studies, neither regimen tested will be advanced to a Phase III trial. 相似文献

Purpose: A phase II trial combining cisplatin, carboplatin and etoposide was conducted in previously untreated patients with stage
IIIB and IV small-cell lung cancer, in an attempt to increase response rates and prolong survival. Methods: Previously untreated patients with small-cell lung cancer, with measurable disease, aged ≤ 72 years, performance status
≤ 2, and adequate hematologic, hepatic and renal function were enrolled in the study. They were treated with 80 mg/m2 cisplatin on day 1, 100 mg/m2 carboplatin on days 2, 3 and 8, and 50 mg/m2 etoposide on days 1, 2, 3 and 8. Results: A total of 46 patients (20 with stage IIIB and 26 with stage IV disease) were enrolled in the study. A total of 186 courses
of chemotherapy were given, and the dose was reduced in 27 courses (15%). The chemotherapy was repeated for four or more courses
in 30 patients. There were 10 complete responses and 32 partial responses, for a total response rate of 91% (95% confidence
interval, 79% to 98%). The median survival time and 2-year survival rates were 18 months and 22% for stage IIIB disease, and
14 months and 15% for stage IV disease. Major side effects were hematologic: leukopenia, anemia, and thrombocytopenia of grade
3 or more occurred in 48%, 46%, and 43% of patients, respectively. Conclusions: The three-drug regimen of cisplatin, carboplatin and etoposide is feasible and active against small-cell lung cancer.
