Clinical TrialA phase I study of ifosfamide/carboplatin/etoposide/paclitaxel in advanced lung cancer.
A phase I study was conducted to define the maximally tolerated dose and toxicity profile of the ifosfamide/carboplatin/etoposide/paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) (ICE-T) regimen in advanced lung cancer. This chemotherapy program uses paclitaxel given as a 24-hour continuous infusion in conjunction with full-dose ICE chemotherapy with growth factor support. The dosage of paclitaxel was escalated from 75 to 225 mg/m2. ⋯ The results of this study suggest that with growth factor support, it is possible to safely administer full-dose, single-agent paclitaxel in conjunction with full-dose ICE chemotherapy. We will soon be initiating a phase II study of the ICE-T regimen using paclitaxel at 225 mg/m2 as a 24-hour continuous infusion in advanced lung cancer. We will also conduct a phase I study of ICE-T, with paclitaxel administered as a 3-hour continuous infusion.

Clinical TrialConcurrent paclitaxel/cisplatin with thoracic radiation in patients with stage IIIA/B non-small cell carcinoma of the lung.
Nine patients with stage IIIB non-small cell lung cancer were entered into a phase II trial designed to determine the feasibility of giving a combination of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) plus cisplatin concurrent with thoracic radiation. Paclitaxel was given as a 24-hour infusion (135 mg/m2) followed by cisplatin (75 mg/m2) every 4 weeks, for a total of four cycles. Thoracic radiation was given concurrently with the first two cycles of chemotherapy, for a total dose of 64.8 Gy over 6 weeks. ⋯ All patients were able to receive the full dose of radiation, although half of the patients required some modification of the chemotherapy regimen. There was one complete response and four partial responses, yielding a 56% overall response rate. This study demonstrates that it is feasible to treat patients with stage IIIB non-small cell lung cancer with paclitaxel/cisplatin plus concurrent thoracic radiation, with a degree of toxicity comparable with that associated with a degree of toxicity comparable with that associated with other concurrent combined-modality regimens for this disease.

Clinical TrialPreliminary analysis of a phase II study of weekly paclitaxel and concurrent radiation therapy for locally advanced non-small cell lung cancer.
Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) is an attractive agent to combine with radiation for non-small cell lung cancer. We have been conducting clinical trials of weekly paclitaxel and concurrent radiation therapy. In a phase I study in non-small cell lung cancer, we determined the maximum tolerated dose of paclitaxel to be 60 mg/m2/wk with radiation. ⋯ Twenty percent of patients had grade 4 esophagitis. Only 8% of patients had grade 3 neutropenia. Combined-modality therapy with paclitaxel and radiation is a promising treatment for locally advanced non-small cell lung cancer with a high response rate and acceptable toxicity.

Clinical TrialPaclitaxel and carboplatin in the treatment of advanced non-small cell lung cancer.
Based on the superior response rates (21% to 24%) of patients treated with single-agent paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) in Eastern Cooperative Oncology Group and M. D. Anderson Cancer Center trials in non-small cell lung cancer (NSCLC) and on the superior 1-year survival rates of NSCLC patients treated with carboplatin in a randomized study of cisplatin combination and analogues, we initiated a phase II trial of paclitaxel/carboplatin in patients with stage IV or effusion-positive stage III NSCLC. ⋯ The objective response rate is 50%, with three complete, 12 partial, and five minor responses. We conclude that the paclitaxel/carboplatin combination is active in advanced NSCLC and, with AUC-based dosing of carboplatin, can be given at 3-week intervals. Although dose limiting at a paclitaxel dose of 135 mg/m2, granulocytopenia can be reduced substantially with granulocyte colony-stimulating factor, allowing sequential dose escalation of paclitaxel to 175 mg/m2 and 215 mg/m2 in 70% of patients receiving three or more cycles.

ReviewNew treatment agents for advanced small cell and non-small cell lung cancer.
The cure rate for lung cancer remains low (13%) primarily due to early systemic spread and the inability to cure systemic disease. These facts have led to pessimism regarding the role of chemotherapy, especially in non-small cell lung cancers. ⋯ Early combination studies show even higher response rates when paclitaxel is combined with cisplatin or carboplatin. Ultimately, randomized trials will be needed to define the optimal use of paclitaxel and other recently developed new agents in lung cancer.
