Docetaxel (Taxotere) and vinorelbine in the treatment of non-small cell lung cancer.
The efficacy and safety of a combination of docetaxel (Taxotere; Rhône-Poulenc Rorer, Antony, France) and vinorelbine were evaluated in two phase II studies including 46 and 39 chemotherapy-naive patients with non-small cell lung cancer, respectively. In the first study, vinorelbine 25 mg/m2 was given on day 1 and docetaxel 100 mg/m2 on day 2, with recombinant human granulocyte colony-stimulating factor support from day 5 until day 12, every 3 weeks. In the second study, docetaxel 75 mg/m2 was given on day 1 and vinorelbine 20 to 25 mg/m2 on days 1 and 5 in a 3-week schedule. ⋯ The overall response rates were 33% and 39%, respectively. It is concluded that combination therapy with docetaxel/ vinorelbine or with docetaxel/vinorelbine/cisplatin has antitumor activity in the treatment of non-small cell lung cancer. Granulocytopenia and febrile neutropenia are the most severe toxicities that limit the usefulness of these regimens.

Clinical TrialIfosfamide/carboplatin/etoposide/paclitaxel in advanced lung cancer: update and preliminary survival analysis.
The primary objective of this study was to define the maximum tolerated dose and toxicity profile of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ), given as a 24-hour infusion, in conjunction with ifosfamide/carboplatin/etoposide (ICE) chemotherapy in patients with advanced lung cancer. Paclitaxel was escalated from 75 to 225 mg/m2 in 25-mg/m2 increments. All patients received granulocyte colony-stimulating factor 5 microg/kg/d from day 4 until the neutrophil count was > or = 10,000/microL. ⋯ Survival was almost identical between stage IIIA and stage IV subsets. We conclude that it is possible to safely administer full-dose single-agent paclitaxel with granulocyte colony-stimulating factor support in conjunction with full-dose ifosfamide/carboplatin/etoposide chemotherapy. While response rates observed were not particularly notable, median survival is considerably longer than that usually achieved with combination chemotherapy in advanced lung cancer.

Clinical TrialChemoradiotherapy for poor-risk stage III non-small cell lung cancer.
Cisplatin-based chemoradiotherapy is becoming a standard treatment for patients with stage III non-small cell lung cancer (NSCLC). However, a significant proportion of patients with lung cancer also present with co-morbid conditions that indicate a poor prognosis and poor tolerance of treatment. We have completed a phase I/II study to evaluate the tolerability and efficacy of carboplatin-based chemoradiotherapy for patients with poor-risk stage III NSCLC. ⋯ The median survival was 12 months, and the 2- and 3-year survival rates were 30% and 20%, respectively. In conclusion, this treatment regimen was relatively well tolerated, with promising response and survival in patients with poor-risk stage III NSCLC. This pilot study provides a basis for further investigation of this treatment regimen.

Clinical TrialWeekly paclitaxel/cisplatin with concurrent radiotherapy in patients with locally advanced non-small cell lung cancer: a phase I study.
We designed a phase I study to determine the maximum tolerated doses of weekly cisplatin and paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) (doses escalated alternately) when given concurrently with standard or hyperfractionated radiotherapy (RT) and to define the nature of the dose-limiting toxicity. Chemotherapy-naive patients with locally advanced non-small cell lung cancer received weekly combination cisplatin/paclitaxel with concurrent local RT. Radiation therapy was initially given at the dose of 1.2 Gy twice daily x 5 d/wk x 5 weeks (total dose, 60 Gy). ⋯ We thus conclude that the cisplatin/paclitaxel combination given weekly can be safely administered concurrent with both standard or hyperfractionated RT. Hyperfractionation is associated with a higher incidence of severe esophagitis and required a slight reduction in cisplatin dose. To verify whether the use of a daily schedule translates into a better therapeutic index, a new phase I study is under way, testing twice-daily cisplatin/paclitaxel concurrently with hyperfractionated RT.

Clinical TrialA phase I study of cisplatin, etoposide, and paclitaxel in small cell lung cancer.
This phase I study was designed to determine the maximum tolerated dose of paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) with standard doses of cisplatin and etoposide for patients with untreated, extensive-stage small cell lung cancer. Secondary objectives were to determine the toxicities, response rate, response duration, and overall survival in this cohort. Twenty-four patients were enrolled into four dose levels. ⋯ Neutropenia was frequent but was not associated with significant morbidity. The recommended doses for future clinical trials are paclitaxel 175 mg/m2 IV over 3 hours on day 1 with cisplatin 80 mg/m2 IV on day 1 and etoposide 80/160 mg/m2 IV on day 1 and orally on days 2 and 3. Growth factor support should be used according to American Society of Clinical Oncology guidelines.
