A phase II trial of concurrent chemoradiation therapy followed by consolidation chemotherapy with oral etoposide and cisplatin for locally advanced inoperable non-small cell lung cancers

We report a phase II study to evaluate the survival rate, response rate and toxicity of concurrent chemoradiation therapy (CCRT) followed by consolidation chemotherapy (CT) with oral etoposide and cisplatin for patients with locally advanced inoperable non-small cell lung cancer (NSCLC). Fifty-four patients with locally advanced inoperable NSCLC who had received no prior therapy were enrolled into this trial between May 1995 and December 2000. Treatment consisted of two cycles of concurrent CT and four cycles of consolidation CT with oral etoposide (50 mg/m2) on days 1-14 during the CCRT courses and on days 1-21 during the consolidation CT courses, plus cisplatin (75 mg/m2 i.v.) on day 1 of a 28-day cycle. Conventional radiotherapy (1.8 Gy/fraction, 63 Gy over 7 weeks) was delivered from day 1 of the CT. Fifty-two patients were evaluable for response. Twelve patients (22%) achieved complete responses, and 32 patients (60%) achieved partial responses, for an overall response rate of 82% with a median duration of response of 9.1 months. Forty-three per cent developed grade 4 haematological toxicity, 11% grade 3 or 4 oesophagitis and 7% grade 3 or 4 lung toxicity. There were two treatment-related deaths, one from radiation pneumonitis and the other from sepsis. After a median follow-up duration of 50 months (range 20-85), the median overall survival time was 15.3 months (95% CI, 9.7-20.8), and the 1-, 2-, 3-, and 5 year overall survival rates were 62, 40, 30 and 16%, respectively. The duration of median progression-free survival was 12.3 months (95% CI, 7.4-17.3), and the 1-, 2-, 3-, and 5-year progression-free survival rates were 47, 40, 29 and 23%, respectively. Thus, concurrent conventional chest radiotherapy with oral etoposide plus cisplatin followed by consolidation CT led to an encouraging survival rate and prolongation of the time to progression, with moderate toxicity in patients with locally advanced inoperable NSCLC.     

Phase III trial comparing a defined duration of therapy versus continuous therapy followed by second-line therapy in advanced-stage IIIB/IV non-small-cell lung cancer.

PURPOSE: To compare four cycles of therapy versus continuous therapy to determine the optimal duration of chemotherapy in advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Stage IIIB/IV NSCLC patients were randomized to arm A (four cycles of carboplatin at an area under the curve of 6 and paclitaxel 200 mg/m(2) every 21 days) or arm B (continuous treatment with carboplatin/paclitaxel until progression). At progression, all patients on both arms were to receive second-line weekly paclitaxel at 80 mg/m(2)/wk. The primary end points were survival and quality of life (QOL). RESULTS: Two hundred thirty patients were randomized. Fifty-seven percent of arm A patients completed four courses of therapy. In the 116 arm B patients, the median number of cycles delivered was four (range, zero to 19 cycles). Forty-two percent received five or more cycles; 18% received eight or more cycles. Overall response rates were 22% and 24% for arms A and B, respectively (P =.80). Median survival time and 1-year survival rates were 6.6 months and 28% for arm A and 8.5 months and 34% for arm B, respectively (log-rank P =.63). Rates of hematologic and nonhematologic toxicity were similar between the two arms, except for neuropathy. The rate of grade 2 to 4 neuropathy increased from 19.9% (95% confidence interval [CI], 13.6% to 26.2%) at cycle 4 to 43% (95% CI, 28.6% to 57.4%) at cycle 8. There were no differences in QOL. Only 45% of patients received second-line therapy (42% in arm A v 47% in arm B, P =.42). CONCLUSION: This study shows no overall benefit in survival, response rates, or QOL to continuing treatment with carboplatin/paclitaxel beyond four cycles in advanced NSCLC.     

Phase II randomized trial of tri-weekly versus days 1 and 8 weekly docetaxel as a second-line treatment of advanced non-small cell lung cancer

BACKGROUND: For orientals, titrating doses of docetaxel (60-66 mg/m(2)) have shown equal effectiveness and fewer side effects as a second-line chemotherapy for patients with advanced non-small cell lung cancer (NSCLC). Under such doses, there were no comparative data between classic tri-weekly and Days 1 and 8 weekly schedules. METHODS: This Phase II randomized prospective study was designed to compare the toxicity profile, efficacy and quality-of-life (QOL) between these two schedules of docetaxel in the treatment of previously treated patients with advanced NSCLC. Fifty patients were randomized to docetaxel arm A (66 mg/m(2) Day 1) and B (33 mg/m(2) Days 1 and 8) given every 3 weeks. RESULTS: The overall response rates (ORRs) were 12 and 24% in arm A and B, respectively (P = 0.46), and disease control rates were 52 and 48%. The median time-to-progression (TTP) was 11.3 and 12.7 weeks and median survivals were 33.4 and 27.6 weeks, respectively. Both arms have same 1 year (36%) and 2 year survivals (12%). Arm A had significantly higher neutropenia but less compromised QOL. In this study, the response of second-line chemotherapy was significantly better in the group that was response to front-line chemotherapy (P = 0.032). CONCLUSIONS: While Days 1 and 8 weekly docetaxel schedules show higher ORR and less hematological toxicity, there is no advantage to tri-week schedule in terms of TTP and survival, but more compromised QOL.

A phase III randomised study comparing two different dose-intensity regimens as induction chemotherapy followed by thoracic irradiation in patients with advanced locoregional non-small-cell lung cancer.

PURPOSE: The aim of this study was to determine the role of chemotherapy dose intensity in patients with initially unresectable non-metastatic non-small-cell lung cancer (NSCLC), with survival as primary end point, by testing two different regimens as induction chemotherapy followed by thoracic irradiation. PATIENTS AND METHODS: Patients had pathologically proven NSCLC, an initially unresectable non-metastatic tumour without homolateral malignant pleural effusion, no prior history of malignancy and had received no prior therapy. Treatment was randomised for chemotherapy between three courses of MIP (mitomycin C 6 mg/m2; ifosfamide 3 g/m2; cisplatin 50 mg/m2) or SuperMIP (mitomycin C 6 mg/m2; ifosfamide 4.5 g/m2; cisplatin 60 mg/m2, carboplatine 200 mg/m2), followed by chest irradiation (60 Gy; five times per week, for 6 weeks). If the tumour became resectable after chemotherapy, surgery was performed, followed by mediastinal irradiation. RESULTS: A total of 351 patients were eligible: 176 in the MIP arm and 175 in the SuperMIP arm, with 43% and 51% stages IIIA and IIIB, respectively. There was a significantly higher objective response rate with SuperMIP (46%) compared with MIP (35%) (P=0.03) [95% confidence interval (CI) for the difference between the response rates, 1% to 22%]. After induction chemotherapy, surgery was performed in 54 (15%) patients (27 per arm) and chest irradiation in 203 (57%) patients (102 in the MIP arm and 101 in the SuperMIP). In terms of survival, there was no statistically significant difference between the two study arms (P=0.16), with median survival times of, for MIP and SuperMIP, respectively, 12.5 (95% CI 10.1-14.9) and 11.2 (95% CI 9.7-12.8) months. Haematological toxicity and dosage reductions were higher with SuperMIP, which was nevertheless associated with a significantly increased absolute dose intensity. CONCLUSIONS: High dose-intensity induction chemotherapy does not improve survival in initially unresectable non metastatic NSCLC.     

A randomised phase III trial comparing consolidation treatment with further chemotherapy to chest irradiation in patients with initially unresectable locoregional non-small-cell lung cancer responding to induction chemotherapy

Purpose: A phase III randomised trial was conducted in patients with non-metastatic unresectable non-small-cell lung cancer in order to compare, in responders to induction chemotherapy, consolidation treatment by further chemotherapy to chest irradiation.Patients and methods: A total of 462 untreated NSCLC patients were eligible for three courses of induction chemotherapy (MIP) consisting of cisplatin (50 mg/m2), ifosfamide (3 g/m2) and mitomycin C (6 mg/m2). It was proposed that objective responders be randomised to either three further courses of MIP or to chest irradiation (60 Gy; 2 Gy per fraction given over six weeks).Results: An objective response rate of 35% was achieved; 115 patients (including 52% with initial stage IIIA and 44% with initial stage IIIB) were randomised to consolidation treatment, 60 of them to further chemotherapy and 55 to chest radiotherapy. There was no significant difference in survival between the two arms, with a respective median and two-year survival of 42 weeks (95% confidence intervals (95% CI): 35–51) and 18% (95% CI: 8–28) for chemotherapy and 54 weeks (95% CI: 43–73) and 22% (95% CI: 11–33) for irradiation. There was also no statistical difference for response duration between the two arms but chest irradiation was associated with a significantly greater duration of local control than chemotherapy (median duration times: 158 vs. 31 weeks, P = 0.0007).Conclusions: For non-metastatic unresectable NSCLC treated by an induction chemotherapy regimen containing cisplatin and ifosfamide, if an objective response is obtained, consolidation treatments by further chemotherapy or by chest irradiation result in non-statistically different survival distributions, although a better local control duration is observed with radiotherapy.     

A phase I-II study of docetaxel-ifosfamide-cisplatin (DIP) combination chemotherapy regimen in advanced nonsmall cell lung cancer

In an attempt to develop more effective chemotherapy regimens in advanced nonsmall cell lung cancer (NSCLC), we evaluated docetaxel-ifosfamide-cisplatin (DIP) based on our previous experience with paclitaxel-ifosfamide-cisplatin. Patients with advanced NSCLC (stages III-IV), WHO-PS< or =2, no prior chemotherapy and unimpaired hematopoietic and organ function were eligible. Chemotherapy was administered in successive dose levels (DLs) and included docetaxel (80-100 mg/m2 day 1), ifosfamide (4-5 g/m2) and cisplatin (80-100 mg/m2), both divided over days 1 and 2 every 21 days. G-CSF (lenograstin) was administered from days 4-13. Fifty-five patients were accrued (phase I: 15; phase II: 40) and all are evaluable for response and toxicity: median age = 58 (40-72); PS = 1 (0-2); gender = 48 males, 7 females; stages IIIA = 8, IIIB = 19, IV = 28; and histologies were adenocarcinoma (29), squamous (20), large cell (6). Metastatic sites at diagnosis included lymph nodes (33), bone (8), liver (6), brain (6), lung nodules (9), adrenals (7) and soft tissue (1). The dose-limiting toxicity (DLT) was reached at DL4 (Docetaxel: 100 mg/m2-Ifosfamide: 5 g/m2-Cisplatin: 100 mg/m2) consisting of 2 cases of febrile neutropenia (FN), and DL3 (Docetaxel: 100 mg/m2-Ifosfamide: 5 g/m2-Cisplatin: 80 mg/m2) was considered as the maximum tolerated dose (MTD) and recommended for further phase II testing. Among evaluable patients in phase II, 31/46 (67%; CI = 54-81%) responded; 4 were complete responses, 27 partial responses, 12 with stable disease and 3 with progressive disease. The median response duration was 7 months (2-21+), median time to progression (TTP) 8 months (1-23+) and median overall survival (OS) 13 months (2-23+). The 1-year survival was 57%. Grade (Gr) 3/4 toxicities included neutropenia 39/46 with 27 developing Gr4 (< or =7 days) and 20% FN managed successfully with broad-spectrum antibiotics, thrombocytopenia Gr3 3/46-Gr4 1/46, no Gr3 neuropathy, Gr1-2 CNS toxicity in 12, no renal toxicity, 15 Gr2 myalgias, 17 Gr2 diarrhea and 10 Gr3 vomiting. In the present phase I-II study, DIP appears highly active and tolerable in advanced NSCLC in the outpatient setting. Randomized comparisons to current standard 2-drug regimens will be warranted.     

Induction chemotherapy with carboplatin/paclitaxel followed by surgery or standard radiotherapy and concurrent daily low-dose cisplatin for locally advanced non-small cell lung cancer (NSCLC)

Five-year survival in patients with unresectable non-small-cell lung cancer (NSCLC) is less than 10%. In the present phase II study, 43 patients with locally advanced stage IIIA or selected IIIB NSCLC were given four courses of carboplatin AUC = 6 and paclitaxel 200 mg/m2 (3-hour infusion), every 3 weeks. Responsive patients, when possible, underwent surgery followed by standard radiotherapy (50 Gy) or radiotherapy (60 Gy), with concurrent cisplatin as intravenous continuous infusion of 4 mg/m2/d. Sixteen of the 42 evaluable patients achieved partial response (38%) and 3 complete response (CR) (7%) for an overall response rate of 45% (95% CI 30.1-60.2). R0 resectability rate was 29%, with 21% of pathologic CRs. Three more CRs were achieved with concurrent chemoradiotherapy in responsive but unresected patients. Grade III/IV hematologic toxicity was 9%, while one perioperative death occurred. The median duration of response was 14 months (range: 3-44+); median survival was 15 months (range: 9-47+). One-year and 2-year survival rates were 51% and 22%, respectively. The median survival in the responsive resected patients was 26 months, with 2-year survival of 57%. Carboplatin/paclitaxel represents an effective and well-tolerated induction therapy, suggesting its possible role in combination with radiotherapy as neoadjuvant treatment in locally advanced NSCLC in alternative to cisplatin-based regimens.

Rational drug sequencing of paclitaxel, gemcitabine and carboplatin in patients with untreated stage IV and select stage IIIB non-small cell lung cancer

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.     

Phase II trial of weekly docetaxel and gemcitabine for previously untreated, advanced non-small cell lung cancer

Docetaxel and gemcitabine combination chemotherapy has been reported to be active against non-small cell lung cancer (NSCLC) and myelosuppression is the most common dose-limiting toxicity. This prospective phase II study was designed to test the hypothesis that better tolerance and increased dose intensity might be achieved if patients are treated with weekly administration schedule. Thirty-five patients with stage IIIB/IV NSCLC and a performance status 0-2 received first-line chemotherapy with docetaxel 35mg/m2 and gemcitabine 600mg/m2 on days 1, 8 and 15. Treatment was repeated every 4 weeks, for up to 4 cycles. In total, 85 chemotherapy cycles were given (median, 2; range, 1-4). Other than the completion of all 4 planned cycles (n=6), the main reasons for treatment discontinuation were toxicity (n=15) and progressive disease (n=14). The most frequently encountered toxic effects were anemia (52% of patients), nausea and vomiting (60%), fatigue (71%) and anorexia (57%). One patient died of bilateral pneumonitis, which developed shortly after the administration of second cycle. Disease control (objective response and stable disease) in the intent-to-treat (ITT) population was achieved in 60% of patients and the overall response rate was 29% (95% CI, 14-44%). With a median follow-up duration of 13 months, the median progression-free survival and overall survival were 2.8 (95% CI, 0.7-4.8) months and 10.6 (95% CI, 7.0-14.3) months, respectively. In conclusion, weekly schedule of docetaxel and gemcitabine has modest activity with acceptable toxicity profile in advanced NSCLC, but as high frequency of early discontinuation occurred does not merit further study with the present regimen.     

Japanese experience with second-line chemotherapy with low-dose (60 mg/m2) docetaxel in patients with advanced non-small-cell lung cancer

PURPOSE: To assess the efficacy and toxicity of relatively low-dose docetaxel (60 mg/m2) for previously treated advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients with advanced (clinical stage IIIA-IV) NSCLC who had previously undergone at least one series of chemotherapy were enrolled. Previous paclitaxel use was allowed, but docetaxel was not. Docetaxel was administered at an initial dose of 60 mg/m2 intravenously on day 1 over 90 min every 3 weeks. RESULTS: From June 1997 to November 1999, 22 patients were entered into this study. The total number of cycles delivered to 22 patients was 53, with a median per patient of 2. Four patients achieved a partial response (PR), and the overall response rate was 18.2% (95% confidence interval 5.1-40.3%). The median time to progression was 13.7 weeks. The median survival time was 7.8 months, and the 1-year survival rate was 25%. About 73% of patients experienced grade 3 or 4 neutropenia. Neutropenic fever was observed in four patients (18%). Non-hematologic toxicities were generally mild. No treatment-related deaths occurred. CONCLUSIONS: Although the validity of the results of this study is limited due to the small and monoracial study population examined, low-dose (60 mg/m2) docetaxel for previously treated advanced NSCLC appears to yield antitumor activity and survival benefit comparable to those obtained with the conventional dose (100 mg/m2).     

Phase II study of paclitaxel (Genaxol) and cisplatin combination in treating Chinese patients with advanced non-small cell lung cancer (NSCLC)

PURPOSE: To assess the efficacy of 3-h paclitaxel infusion (Genaxol) combined with cisplatin as the first line chemotherapy for patients with advanced/metastatic non-small cell lung cancer (NSCLC). The aim of the present study is to evaluate the efficacy, safety, and quality of life of the combination of paclitaxel (Genaxol) and cisplatin on Chinese patients. METHODS: Forty-five patients with histology confirmed NSCLC, who met the selection criteria were enrolled in this study between June 1999 and May 2000. They were all at an advanced stage, i.e. stage IIIB with pleural effusion, or stage IV. Paclitaxel (Genaxol) at a dose of 175 mg/m(2) and cisplatin at a dose of 75 mg/m(2) were administered every 3 weeks. RESULTS: Of the 45 eligible patients, one had a CR and 19 achieved a PR. The overall response was 44.4% (95% CI: 29.3-59.5%). Eleven (24.4%) patients were in stable disease. The median time to disease progression for all patients was 5.5 months (95% CI: 4.0-7.0 months). The median survival was 11.1 months (95% CI: 6.6-15.6 months), the 1-year survival probability was 46.5%. Major non-hematology toxicities were asthenia, paresthesias, nausea, and vomiting. Hematological toxicity results showed 18 (40%) patients experienced grade 3/4 neutropenia but there was no febrile neutropenia, three (6.6%) patients experienced Grade 3 anemia, and one (2.2%) patient experienced Grade 3 thrombocytopenia. CONCLUSIONS: The combined paclitaxel and cisplatin regimen is safe and effective in the treatment of NSCLC but the quality of life is disappointed.     

A phase II study of oxaliplatin and paclitaxel in patients with advanced non-small-cell lung cancer.

PURPOSE: To evaluate the efficacy and toxicity of oxaliplatin and paclitaxel as first-line therapy for patients with advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: The treatment regimen was given as defined in a phase I investigation in patients with previously treated ovarian cancer. It consisted of paclitaxel 175 mg/m(2) (1-h infusion) and oxaliplatin 130 mg/m(2) (2-h infusion) given every 21 days. Eligible patients had stage IIIB (pleural effusion)/IV NSCLC, measurable disease, no prior chemotherapy, Eastern Cooperative Oncology Group performance status 0-2, and adequate hematological, renal and hepatic function. RESULTS: A total of 38 patients were enrolled with the following characteristics: 29% male (n = 11); 71% female (n = 27); median age 64.5 years (range 37-78); performance status of 0-1 84% (n = 32); stage IIIB 8% (n = 3); stage IV 92% (n = 35). One hundred and eighty-one cycles were administered, with a median of four per patient (range one to 12). The overall objective response rate for all 38 patients was 34.2% [95% confidence interval (CI) 19.6% to 51.4%]. This response rate includes 13 patients who met criteria for a partial response. No complete responses were observed. Median overall survival time was 9.2 months (95% CI 6-12.4) and median progression-free survival time was 4.3 months (95% CI 2.1-6.5). The 1- and 2-year overall survival rates were 37% and 21%, respectively. Hematological toxicity included six patients with grade 4 neutropenia. Non-hematological toxicity consisted mainly of grades 1 and 2 neurosensory toxicity. Laryngodysesthesia was observed in two patients following oxaliplatin infusion. No grade 4 non-hematological toxicities were encountered. CONCLUSION: This regimen is well tolerated, and demonstrates activity in patients with advanced NSCLC.     

ALIMTA (pemetrexed disodium) as second-line treatment of non-small-cell lung cancer: a phase II study.

BACKGROUND: The purpose of this study was to evaluate ALIMTA (pemetrexed disodium, LY231514), a multi-targeted antifolate with first-line activity against non-small-cell lung cancer (NSCLC), in a second-line setting. PATIENTS AND METHODS: Patients with NSCLC were eligible for this phase II study if they had progressive disease within 3 months after first-line chemotherapy or progression while being treated with first-line chemotherapy. In 81 patients studied, two cohorts of patients were assigned based on whether the first-line therapy had included a platinum regimen. ALIMTA was administered at 500 mg/m2 by 10-min intravenous infusion once every 21 days. RESULTS: The response rate in the 79 evaluable patients with poor prognostic features was 8.9% [95% confidence interval (CI) 2.6% to 15.1%]. The response rate in the platinum-pretreated group was 4.5% and 14.1% in the non-platinum-pretreated group. The median duration of response was 6.8 months (95% CI 3.4-7.8 months, 0% censoring). The median survival time was 5.7 months (95% CI 4.0-8.3 months, 7.6% censoring). The probability of survival for at least 6 months was estimated to be 48%. The median time to disease progression was 2 months (95% CI 1.4-2.8 months, 0% censoring). The principal toxicity was myelosuppression, which was reversible. CONCLUSIONS: ALIMTA is active in a second-line setting in non-platinum-pretreated NSCLC patients progressing within 3 months of first-line chemotherapy. This study demonstrates that it is possible to evaluate new drugs against NSCLC in a second-line setting.

Docetaxel (Taxotere) plus cisplatin: an active and well-tolerated combination in patients with advanced non-small cell lung cancer

The activity of the combination of intravenous docetaxel 75 mg/m2 plus cisplatin 100 mg/m2 administered every 3 weeks for 3 cycles then every 6 weeks was investigated in 51 chemotherapy naive patients with locally advanced or metastatic non-small cell lung cancer (NSCLC). The population was 92% male, with a median age of 54 years and median performance status of 1; 80% of patients had metastatic disease, including 37% with bone involvement. All patients received prophylactic premedication (ondansetron, dexamethasone plus cetirizine) and standard hyperhydration. With a median of 4 treatment cycles (range 1-9), 14 of 42 evaluable patients responded (overall response rate 33.3%, 95% CI 19.6-49.6%); the median response duration was 7.3 months, median survival 8.4 months, and 1-year survival rate 35%. The most common adverse event was neutropenia, occurring in two-thirds of patients. Neurosensory effects were cumulative but generally mild. No treatment-related deaths occurred. This combination of docetaxel/cisplatin showed activity in advanced NSCLC. While it was not clearly superior to single-agent docetaxel, due to differences in prognostic factors among the patients in open trials, a randomised study would be needed to demonstrate definitively whether cisplatin adds to the activity of docetaxel or not.     

A phase II study of days 1 and 8 combination of docetaxel plus gemcitabine for the second-line treatment of patients with advanced non-small-cell lung cancer and good performance status

OBJECTIVE: We conducted a phase II trial to evaluate the efficacy and toxicity of a combination consisting of second-line docetaxel and gemcitabine in patients with advanced non-small-cell lung cancer (NSCLC) previously treated with platinum-based chemotherapy. PATIENTS AND METHODS: Eligibility criteria: histologically confirmed advanced NSCLC with progressive disease to platinum-based chemotherapy, ECOG performance status (PS) 0 or 1, and adequate kidney, liver and bone marrow function. Treatment consisted of docetaxel 36 mg/m(2) i.v. over 60 min followed by gemcitabine 1000 mg/m(2) i.v. over 30 min on days 1 and 8 of each 3-week cycle for a planned six cycles or unacceptable toxicity. RESULTS: Of the 52 patients enrolled, 50 were evaluable for response and toxicity. The mean age was 59 years (range 42-79), 46 male and 4 female. Histology subtypes were: adenocarcinoma 26 patients, bronchioloalveolar 1 patient, large cell carcinoma 5 patients, and squamous cell carcinoma 18 patients. Thirty-eight patients had ECOG PS 1 and 12 patients had PS 0. The median number of cycles administered was four (range 2-6). The overall response rate was 28%. The median follow-up was 9 months (range 5-34 months). The median survival time (MST) was 8.2 months (95% CI, 4-12%), and the 1-year survival was 25%. The median progression-free survival was 4.4 months (95% CI, 2-6%). In the Cox regression model, survival was only significantly affected by the PS. The median survival in patients with PS 0 was 17.8 months (95% CI, 18.8-21.8%) compared with a median survival for patients with PS 1 of 6.1 months (95% CI, 4.1-8.2%) (P=0.0057). Toxicity: three patients had grade 3 anemia, three patients had grade 3 thrombocytopenia, four patients had grade 3 neutropenia and only one patient developed grade 4 febrile neutropenia. Non-hematologic toxicity was also mild; the most frequent was asthenia, with grade 3 in eight patients (16%), and one patient with grade 4. CONCLUSION: This regimen of docetaxel in combination with gemcitabine in advanced second-line NSCLC is an active and safe regimen.     

Paclitaxel, cisplatin, and gemcitabine combination chemotherapy within a multidisciplinary therapeutic approach in metastatic nonsmall cell lung carcinoma

BACKGROUND: Cisplatin-based chemotherapy combinations improve quality of life and survival in advanced nonsmall cell lung carcinoma (NSCLC). The emergence of new active drugs might translate into more effective regimens for the treatment of this disease. METHODS: The objective of this study was to determine the feasibility, response rate, and toxicity of a paclitaxel, cisplatin, and gemcitabine combination to treat metastatic NSCLC. Thirty-five consecutive chemotherapy-naive patients with Stage IV NSCLC and an Eastern Cooperative Oncology Group performance status of 0-2 were treated with a combination of paclitaxel (135 mg/m(2) given intravenously in 3 hours) on Day 1, cisplatin (120 mg/m(2) given intravenously in 6 hours) on Day 1, and gemcitabine (800 mg/m(2) given intravenously in 30 minutes) on Days 1 and 8, every 4 weeks. Although responding patients were scheduled to receive consolidation radiotherapy and 24 patients received preplanned second-line chemotherapy after disease progression, the response and toxicity rates reported refer only to the chemotherapy regimen given. RESULTS: All the patients were examined for toxicity; 34 were examinable for response. An objective response was observed in 73.5% of the patients (95% confidence interval [CI], 55.6-87.1%), including 4 complete responses (11.7%). According to intention-to-treat, the overall response rate was 71.4% (95% CI, 53. 7-85.4%). After 154 courses of therapy, the median dose intensity was 131 mg/m(2) for paclitaxel (97.3%), 117 mg/m(2) for cisplatin (97.3%), and 1378 mg/m(2) for gemcitabine (86.2%). World Health Organization Grade 3-4 neutropenia and thrombocytopenia occurred in 39.9% and 11.4% of patients, respectively. There was one treatment-related death. Nonhematologic toxicities were mild. After a median follow-up of 22 months, the median progression free survival rate was 7 months, and the median survival time was 16 months. CONCLUSIONS: The combination of paclitaxel, cisplatin, and gemcitabine is well tolerated and shows high activity in metastatic NSCLC. This treatment merits further comparison with other cisplatin-based regimens.
