A phase I study was conducted to determine the maximum-tolerated dose (MTD) and the dose-limiting toxicities (DLTs) of a CPT-11 plus cisplatin combination as salvage treatment in patients with advanced non-small cell lung cancer (NSCLC). ⋯ The combination of CPT-11 and cisplatin has substantial but manageable toxicity and marginal activity as salvage treatment of patients with NSCLC who have failed taxotere-based front-line chemotherapy: further investigation is warranted to define its precise role in the second-line setting.

Clinical Trial
Thoracic radiotherapy and daily vinorelbine as radiosensitizer in locally advanced non small cell lung cancer: a phase I study.
Experimental studies have shown that vinorelbine is a powerful radiosensitizer in vitro. To date, no reports on clinical activity of the single agent vinorelbine as radiosensitizer have been published. The aim of the present phase I study was to determine the maximum tolerated dose (MTD) of vinorelbine administered daily concurrently with thoracic radiotherapy, with or without amifostine support, in the treatment of locally advanced non small cell lung cancer. ⋯ In conclusion, our data show that the MTD of daily vinorelbine is 4 mg/m(2). Therefore, this is the recommended dose of daily vinorelbine to be administered with concurrent thoracic radiotherapy in a phase II trial. Finally, amifostine administered subcutaneously failed to increase the MTD of daily vinorelbine.

Case Reports
Relief of non-metastatic shoulder pain with mediastinal radiotherapy in patients with lung cancer.
Three patients with lung cancer and shoulder pain for which no local cause could be found are described. All three benefited from a course of palliative radiotherapy to ipsilateral mediastinal disease remote from the site of the pain. It is suggested that the pain is referred from intrathoracic involvement of the phrenic nerve by cancer, and that palliative irradiation of the mediastinum should be considered if investigations fail to reveal a local cause for ipsilateral shoulder pain.

The outcome of limited field irradiation for medically inoperable patients with peripheral stage I non-small cell lung cancer (NSCLC) was analyzed to discuss the elective irradiation of regional lymph nodes. From 1976 through 1994, 36 patients with peripheral stage I NSCLC were treated with definitive radiation therapy (RT) alone at Gunma University hospital. The total dose ranged from 60 to 81 Gy with a 2 Gy-daily standard fractionation, although only one patient received 48 Gy. ⋯ High-dose limited field RT is justified for medically inoperable patients with peripheral stage I NSCLC. The regional nodal irradiation can be omitted in these pulmonary compromised patients because of the low regional relapse rate. Dose-escalation by a conformal RT with a small target volume can be expected to provide a better local control rate and better survival.
