Weekly paclitaxel in the treatment of metastatic and/or recurrent non-small cell lung cancer

Weekly paclitaxel was initially used to exploit the radio sensitizing properties of the drug. However, the observed improvement in therapeutic index with this regimen encouraged further use of weekly regimens, with and without radiotherapy, as a single-agent or in combination with other regimens. Single-agent weekly paclitaxel, at doses ranging from 50 to 200 mg/m(2)/week, has been associated with response rates of 23-56% with acceptable toxicity. Weekly paclitaxel has also been combined with carboplatin and vinorelbine in two-drug combinations and with cisplatin plus gemcitabine and cisplatin plus vinorelbine in three-drug regimens. Response rates with weekly paclitaxel in combination chemotherapy have ranged from 16 to 71%. Paclitaxel is particularly suited to combined modality therapy with radiation in non-small cell lung cancer, because of its modest toxicity profile, significant antineoplastic activity, ease of administration and potential for radiosensitization. Studies of weekly paclitaxel given together with radiotherapy, with or without carboplatin, have produced response rates of 71-86% with median survival durations of 17-20.5 months.
