Multicenter Study Clinical Trial
Sequential versus concurrent paclitaxel and carboplatin for the treatment of advanced non-small cell lung cancer in elderly patients and patients with poor performance status: results of two Phase II, multicenter trials.
The primary objective of these trials was to determine the 1-year survival of advanced non-small cell lung cancer (ANSCLC) patients (> or =70 years with PS 0-2 or > or =18 years with PS 2) receiving sequential paclitaxel and carboplatin (P --> C) or concurrent P + C. The secondary objectives were assessment of toxicities and quality of life. A total of 121 patients with NSCLC were treated. ⋯ The analysis of quality of life (QOL) questionnaires indicated that there were no obvious differences between treatment groups during the study. These drugs and treatment schema were well-tolerated when administered in the community setting and resulted in survival rates that were similar to what is reported in the literature with combination therapy administered to "high risk" patients. Finding the optimal chemotherapy regimen, that can be tolerated, remains a challenge in elderly patients.

Detection of malignancies of the bronchial tree in an early stage, such as carcinoma in situ (CIS), augments the cure rate considerably. It has been shown that the sensitivity of autofluorescence bronchoscopy is better than white light bronchoscopy for the detection of CIS and dysplastic lesions. Autofluorescence bronchoscopy is, however, characterized by a low specificity with a high rate of false positive findings. ⋯ Standard autofluorescence bronchoscopy was used to find suspect lesions in the upper bronchial tree, and these lesions were subsequently characterized spectroscopically using a custom made fiberoptic probe. Autofluorescence spectra of the lesions as well as reflectance spectra were measured. We will show in this preliminary report that the addition of either of these spectroscopic techniques decreases the rate of false positives findings, with the best results obtained when both spectroscopic modalities are combined.

Review
Adjuvant treatment of lung cancer: current status and potential applications of new regimens.
Non-small-cell lung cancer (NSCLC) accounts for approximately 80% of lung cancers diagnosed worldwide. Surgical resection offers the best chance for cure for those patients diagnosed with early-stage disease; however, the vast majority of patients will eventually relapse. Despite complete surgical resection, recurrences are likely due to undetectable microscopic disease at diagnosis, making these patients potential candidates for effective adjuvant therapy. ⋯ Two recently reported landmark studies have demonstrated the survival advantages of adjuvant therapy for patients with early-stage NSCLC. Docetaxel, one of the most active agents for advanced NSCLC, is also regularly used for locally advanced disease as part of neoadjuvant or combined-modality regimens. As recent findings have established the value of adjuvant chemotherapy for early-stage NSCLC, agents such as docetaxel warrant rigorous evaluation in this setting.
