Randomized Controlled Trial Multicenter Study
Phase II study of PKC-alpha antisense oligonucleotide aprinocarsen in combination with gemcitabine and carboplatin in patients with advanced non-small cell lung cancer.
The antisense oligonucleotide aprinocarsen specifically inhibits the transcription of protein kinase C-alpha. This study evaluated the response rate of the combination therapy of aprinocarsen, gemcitabine, and carboplatin in previously untreated patients with advanced non-small cell lung cancer (NSCLC). Secondary objectives included the measurement of time-to-event efficacy parameters and toxicity. ⋯ Enrollment for this study was stopped and the study was terminated in March 2003 due to the results of a large phase III study, which suggested that aprinocarsen did not improve response or add survival benefit to chemotherapy in advanced NSCLC. The addition of aprinocarsen to gemcitabine+carboplatin therapy in patients with NSCLC showed moderate activity. However, this combination resulted in severe thrombocytopenia in the majority of patients.

Multicenter Study Comparative Study
Imaging of gefitinib-related interstitial lung disease: multi-institutional analysis by the West Japan Thoracic Oncology Group.
Gefitinib (Iressatrade mark) is an epidermal growth factor receptor tyrosine kinase inhibitor that has been approved for the treatment of lung cancer in Japan, however, after marketing several cases of severe pulmonary toxicity were reported. The West Japan Thoracic Oncology Group conducted an independent survey of acute pulmonary toxicity and interstitial lung disease (ILD) caused by gefitinib in its member's institutions. The purpose of this study was to clarify the image characteristics of ILD caused by the molecular-targeting drug gefitinib. ⋯ The mortality rate was significantly higher in the patients with pattern D than the other patterns. Pattern D were thought to represent the features of diffuse alveolar damage. In conclusion, the molecular-targeting drug gefitinib induces pulmonary toxicity at a certain rate and the imaging findings of ILD induced by gefitinib are similar to those of pulmonary toxicity induced by conventional antineoplastic agents.

Randomized Controlled Trial
Cisplatin and gemcitabine first-line chemotherapy followed by maintenance gemcitabine or best supportive care in advanced non-small cell lung cancer: a phase III trial.
The primary objective of this randomized phase III study was to show significant difference in median time to progression (TTP) in patients with advanced NSCLC treated with single-agent gemcitabine maintenance therapy versus best supportive care following gemcitabine plus cisplatin initial first-line therapy. ⋯ Maintenance therapy with gemcitabine, following initial therapy with gemcitabine plus cisplatin, was feasible, and produced significantly longer TTP compared to best supportive care alone. Further studies are warranted to establish the place of maintenance chemotherapy in patients with advanced NSCLC.

Randomized Controlled Trial
Phase II study of the combination of gemcitabine and nedaplatin for advanced non-small-cell lung cancer.
We examined the efficacy and safety of the combination of gemcitabine and nedaplatin in patients with untreated advanced non-small-cell lung cancer. Thirty-four patients (24 men and 10 women) with a mean age of 69 years (range, 39-75 years) were treated every 3 weeks with gemcitabine (1,000 mg/m(2) on days 1 and 8) and nedaplatin (100 mg/m(2) on day 1). Four patients had stage IIIB disease and 30 patients had stage IV disease. ⋯ There were no treatment-related deaths. The dose intensities were 89.6% and 86.7%, respectively, of the planned doses of gemcitabine and nedaplatin. Our results suggest that the combination of gemcitabine and nedaplatin is an acceptable treatment for patients with previously untreated advanced non-small-cell lung cancer.
