Randomized Controlled Trial Clinical TrialInduction paclitaxel and carboplatin followed by concurrent chemoradiotherapy in patients with unresectable, locally advanced non-small cell lung carcinoma: report of Fox Chase Cancer Center study 94-001.
The paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ)/carboplatin combination has demonstrated promising activity in patients with incurable non-small cell lung cancer (NSCLC). Our exploratory study is designed to evaluate the efficacy of this combination as induction therapy in patients with locally advanced NSCLC, to determine the maximally tolerated doses of paclitaxel and carboplatin administered every 3 weeks during radical thoracic radiation after induction treatment, and to determine the efficacy of granulocyte colony-stimulating factor (G-CSF) priming before induction treatment, followed by conventional G-CSF, compared with conventional G-CSF alone. Eligibility stipulated Karnofsky performance status > or =70%, < or =5% weight loss, and stages IIIB or bulky IIIA NSCLC. ⋯ Induction paclitaxel/carboplatin therapy is active and well tolerated by patients with locally advanced NSCLC. The maximum tolerated doses of paclitaxel and carboplatin during concurrent thoracic radiation and the role of G-CSF priming are not yet established. Severity of esophagitis corresponds to the extent of esophagus irradiated during concurrent thoracic radiotherapy and chemotherapy.

ReviewDefining the role of paclitaxel in lung cancer: summary of recent studies and implications for future directions.
Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) was first reported to have activity in advanced non-small cell lung cancer (NSCLC) in 1993 and in advanced small cell lung cancer (SCLC) in 1995. Since these original reports, single-agent activity has been confirmed in both NSCLC and SCLC. In NSCLC, the 20% to 25% response rate and median survival times (approximately 40 weeks) are superior to previously reported single-agent therapy. ⋯ Similarly, paclitaxel and carboplatin combinations produce high response rates when given before surgery for operable patients, and the results of randomized trials are needed to confirm the value of this approach. Paclitaxel-based combinations in advanced SCLC can be administered safely and provide high response rates and relatively long survival times. Randomized trials comparing these combinations to older etoposide/cisplatin combinations are in progress.

ReviewFuture perspectives of docetaxel (Taxotere) in front-line therapy.
The recognition that early breast cancer is a systemic disease has led to the development of multimodal treatments incorporating adjuvant hormonal and chemotherapies. Adjuvant strategies have improved the outcome of treatment for early breast cancer, but 50% of women still relapse and develop overt metastatic disease, which is largely incurable. In the search for more effective chemotherapies, the taxoid, docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France), has demonstrated high single-agent activity against metastatic breast cancer, including visceral metastases, and is now in phase III trials of combination adjuvant and front-line therapies. ⋯ The high single-agent activity of docetaxel makes it an excellent candidate for treatments such as induction regimens before high-dose chemotherapy and adjuvant therapies. Short-term treatment regimens such as these should also avoid the cumulative toxicities of docetaxel. It is important that new drugs, such as docetaxel, which have shown promising activity against metastatic disease and could have a significant impact on the natural history of early breast cancer, are investigated as front-line treatments.

Multicenter Study Clinical TrialPaclitaxel (1-hour infusion) plus carboplatin in the treatment of advanced non-small cell lung cancer: results of a multicenter phase II trial.
This study was performed to determine the activity and toxicity of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) given by 1-hour infusion plus carboplatin in the treatment of patients with advanced non-small cell lung cancer when used in a multicenter, community-based setting. The study population included 100 chemotherapy-naive patientswith stage IIIB or IV non-small cell lung cancer, Karnofsky performance status 70 to 100, measurable disease, and adequate kidney, liver, and bone marrow function. All patients received paclitaxel 225 mg/m2 intravenously by 1-hour infusion followed immediately by carboplatin at a targeted area under the concentration-time curve of 6.0 (Calvert formula). ⋯ One patient died as a result of treatment due to sepsis. This large, multicenter, community-based phase II trial demonstrates the efficacy of paclitaxel/carboplatin combination chemotherapy in advanced non-small cell lung cancer. This regimen is relatively well tolerated and when paclitaxel is given by 1-hour infusion, this treatment is easily administered in the outpatient setting.

Clinical TrialA phase II study evaluating the efficacy of carboplatin, etoposide, and paclitaxel with granulocyte colony-stimulating factor in patients with stage IIIB and IV non-small cell lung cancer and extensive small cell lung cancer.
We initiated a phase II pilot study to determine whether adding paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) to combination carboplatin/etoposide is tolerable and active in patients with advanced non-small cell lung cancer and extensive small cell lung cancer. Patients were given carboplatin (area under the concentration-time curve of 6) followed by etoposide 80 to 100 mg/m2 intravenously on days 1 through 3 followed by paclitaxel 200 mg/m2 intravenously over 3 hours on day 3. On days 4 through 18, granulocyte colony-stimulating factor 5 microg/kg was administered subcutaneously. ⋯ None of the four patients with non-small cell lung cancer responded to treatment, while six of seven small cell lung cancer patients have obtained major responses to therapy. We have increased the etoposide dose to 100 mg/m2 in subsequent patients. The combination chemotherapy regimen of carboplatin, etoposide, and paclitaxel is tolerable and active in patients with small cell lung cancer.
