Gemcitabine/carboplatin in advanced non-small cell lung cancer

Gemcitabine/cisplatin is among the most widely used regimens in Europe for first-line treatment of non-small cell lung cancer (NSCLC). Problems with cisplatin use in this setting include significant nonhematologic toxicity and difficulty of use in outpatients. Carboplatin constitutes a reasonable alternative to cisplatin in this combination, since it shows synergy with gemcitabine in vitro, is easier to use in ambulatory patients, and has a better nonhematologic toxicity profile. Studies of gemcitabine/cisplatin on a 28-day schedule (gemcitabine on days 1, 8, 15 and carboplatin on day 1) generally indicate excessive thrombocytopenia. Use of a 21-day schedule (e.g. gemcitabine on days 1 and 8, carboplatin on day 1) is associated with reduced toxicity and comparable efficacy. Results of one randomized phase II study suggest reduced toxicity and reduced objective response rate with gemcitabine/carboplatin versus gemcitabine/cisplatin. We are currently conducting a phase III comparison of gemcitabine 1200 mg/m(2) on days 1 and 8 plus carboplatin at an area under the curve of 5 mg/ml/min on day 1 versus gemcitabine at the same dose plus cisplatin 80 mg/m(2) on day 1 every 21 days in chemotherapy-nai;ve patients with stage IIIB/IV NSCLC; interim analysis indicates comparable response rates (47 and 48%). A better understanding of the relative toxicities of these regimens should be provided by the final results of this trial.     

Randomized phase III study of cisplatin plus irinotecan versus carboplatin plus paclitaxel, cisplatin plus gemcitabine, and cisplatin plus vinorelbine for advanced non-small-cell lung cancer: Four-Arm Cooperative Study in Japan.

BACKGROUND: To compare the efficacy and toxicity of three platinum-based combination regimens against cisplatin plus irinotecan (IP) in patients with untreated advanced non-small-cell lung cancer (NSCLC) by a non-inferiority design. PATIENTS AND METHODS: A total of 602 patients were randomly assigned to one of four regimens: cisplatin 80 mg/m(2) on day 1 plus irinotecan 60 mg/m(2) on days 1, 8, 15 every 4 weeks (IP) carboplatin AUC 6.0 min x mg/mL (area under the concentration-time curve) on day 1 plus paclitaxel 200 mg/m(2) on day 1 every 3 weeks (TC); cisplatin 80 mg/m(2) on day 1 plus gemcitabine 1000 mg/m(2) on days 1, 8 every 3 weeks (GP); and cisplatin 80 mg/m(2) on day 1 plus vinorelbine 25 mg/m(2) on days 1, 8 every 3 weeks (NP). RESULTS: The response rate, median survival time, and 1-year survival rate were 31.0%, 13.9 months, 59.2%, respectively, in IP; 32.4%, 12.3 months, 51.0% in TC; 30.1%, 14.0 months, 59.6% in GP; and 33.1%, 11.4 months, 48.3% in NP. No statistically significant differences were found in response rate or overall survival, but the non-inferiority of none of the experimental regimens could be confirmed. All the four regimens were well tolerated. CONCLUSION: The four regimens have similar efficacy and different toxicity profiles, and they can be used to treat advanced NSCLC patients.     

Gemcitabine plus cisplatin vs. gemcitabine plus carboplatin in stage IIIb and IV non-small cell lung cancer: a phase III randomized trial

PURPOSE: This randomized, multicenter, phase III trial was conducted to compare the tolerability of gemcitabine plus cisplatin (GP) vs. gemcitabine plus carboplatin (GC) in chemonaive patients with stage IIIb and IV non-small cell lung carcinoma (NSCLC). Secondary objectives were to evaluate response, duration of response, time to progressive disease (TTPD), and survival. PATIENTS AND METHODS: Eligible patients were required to have stage IIIb or IV NSCLC, no previous chemotherapy, Karnofsky performance status of at least 70, bidimensionally measurable disease, and age 18-75 years. Randomized patients in both arms were given gemcitabine 1200 mg/m(2) on days 1 and 8, followed on day 1 by cisplatin 80 mg/m(2) (GP) or carboplatin AUC=5 (GC). Treatment cycles were repeated every 21 days for a maximum of six cycles, or until disease progression or unacceptable toxicity occurred. RESULTS: Enrolled patients in both arms, 87 in GP and 89 in GC, were well balanced for demographics and disease characteristics. Dose intensity was 93.8 and 92.7% for gemcitabine in GP/GC arms, respectively; 97.7% for cisplatin and 99.9% for carboplatin. Patients with at least one grade 3/4 toxicity excluding nausea, vomiting or alopecia, were 44% in GP arm and 54% in GC arm. The only significantly different toxicities were, nausea and vomiting in GP and thrombocytopenia in GC group. The overall response rates, median TTPD, response duration and survival were, 41/29%, 5.87/4.75 months, 7.48/5.15 months, and 8.75/7.97 months for GP and GC arms, respectively. CONCLUSION: GP and GC are effective and feasible regimens for advanced NSCLC, and are comparable in efficacy and toxicity. GC may offer acceptable option to patients with advanced NSCLC, especially those who are unable to receive cisplatin.

A case of advanced large cell lung carcinoma for whom fourth-line chemotherapy of cisplatin and gemcitabine proved effective for the first time

CASE: A 56-year-old Japanese man who was suffering from dry cough and right neck mass visited our hospital. Chest X-ray revealed a lung mass shadow in the lower left lung field. We diagnosed it as an advanced large cell carcinoma after conducting transbronchial lung biopsy and neck lymphnode biopsy. A right neck mass enlarged after three chemotherapy regimens of carboplatin and vinorelbine for first-line, docetaxel for second-line, and TS-1 and cisplatin for third-line. Finally, cisplatin (80 mg/m(2), day 1) and gemcitabine (800 mg/m(2), day 1, 8) were administered as fourth-line therapy. Partial response was observed after completing four chemotherapy cycles. CONCLUSION: In this case, the fourth-line chemotherapy, consisting of cisplatin and gemcitabine, proved effective for refractory NSCLC. Further research should be conducted regarding third-line chemotherapy for NSCLC patients with good performance status.     

Phase I trial of fixed dose-rate gemcitabine in combination with carboplatin in chemonaive advanced non-small-cell lung cancer: a Cancer Therapeutics Research Group study

PURPOSE: To determine the maximally tolerated dose (MTD) of gemcitabine administered at a fixed dose-rate of 10 mg/m(2) per min in combination with fixed dose carboplatin, to evaluate the toxicity of this regimen and to determine the pharmacokinetics of plasma gemcitabine. METHODS: Patients with advanced stage non-small-cell lung cancer (NSCLC) received carboplatin (AUC 5) on day 1 followed by gemcitabine at a fixed dose rate of 10 mg/m(2) per min in escalating durations of infusion on days 1 and 8 every 21 days. Pharmacokinetic sampling was obtained on day 1, cycle 1 of treatment. RESULTS: A total of 15 patients received carboplatin and gemcitabine in cohorts of three to six patients at three dose levels. The doses of gemcitabine studied were 600, 750, and 900 mg/m(2). The MTD was reached at 900 mg/m(2). Dose-limiting toxicities were thrombocytopenia and liver failure, and with repeated dosing neutropenia was commonly observed. The recommended phase II dose of gemcitabine was 750 mg/m(2). Partial responses were observed at 600 and 750 mg/m(2) of gemcitabine. Plasma gemcitabine did not reach steady state except in one patient with the durations of infusion studied. Plasma concentrations, however, were above 10 micro mol/l between 20 and 90 min in all patients. CONCLUSIONS: Gemcitabine administered as a 75-min infusion at a fixed dose rate of 10 mg/m(2)/min on days 1 and 8 in combination with carboplatin on day 1 every 21 days is tolerable and active in NSCLC. Pharmacokinetic studies demonstrated that the target plasma gemcitabine concentration above 10 micro mol/l was achieved. Further studies are warranted to compare this regimen against standard regimens of carboplatin and gemcitabine.
