Non-small cell lung cancer at the extremes of age: impact on diagnosis and treatment.

BACKGROUND: Early detection and surgical resection offers the highest likelihood of cure for patients with lung cancer. Patients presenting at the extremes of age may fail to benefit maximally from these interventions. To study the impact of age on stage, histology, symptom, and treatment of patients with non-small cell lung cancer, we undertook a retrospective review. METHODS: One thousand eight hundred two patients with non-small cell lung cancer were identified between 1983 and 1993. Patients were selected by age as less than 45 years (55 patients) and 80 years or more (108 patients), and their medical records were reviewed. RESULTS: Three younger patients (6%) presented with stage I or II disease, yet 15 (32%) underwent thoracic operation. Twenty-seven elderly patients (33%) presented with early stage disease and only 6% underwent operation. The median survival was significantly longer for the younger population with surgically resectable stages of disease (stage I to IIIA) (p < 0.05), whereas no significant difference in survival was seen for the two groups with advanced disease (stage IIIB and IV). CONCLUSIONS: Age significantly affects the presentation and treatment of non-small cell lung cancer patients. Although thoracic operation imparts the greatest survival advantage, this benefit is diminished due to advanced disease in the younger patients and lack of surgical intervention in the elderly.

Cognitive behavior therapy for treatment-refractory panic disorder.

BACKGROUND: The purpose of this pilot study is to assess the efficacy of cognitive behavior therapy for the treatment of patients with panic disorder who experience an incomplete response to a trial of pharmacotherapy. METHOD: Fifteen consecutive patients with a DSM-III-R diagnosis of panic disorder referred for further treatment because of an incomplete response to pharmacotherapy were treated with 12-weeks of group cognitive behavior therapy. Patients were evaluated at baseline, endpoint, and at a mean of 2-months' follow-up to assess changes in panic attack frequency and global outcome. Eight of the 15 patients were deemed to have received an inadequate prior trial of medication at baseline, mainly because of a desire to control their symptoms without medication or fear of withdrawal and/or addiction. Seven of the patients were symptomatic at baseline despite an adequate prior trial of medication. RESULTS: Overall, patients experienced a significant improvement in global function at the end of the cognitive behavior therapy intervention, as well as a decrease in panic attack frequency. Improvement was maintained at follow-up. CONCLUSION: This study is consistent with a growing body of evidence that many patients with panic disorder remain symptomatic over time and are receiving inadequate pharmacotherapeutic treatment. Further, we observed that patients with panic disorder who are incompletely responsive or resistant to pharmacotherapeutic management may benefit from the addition of cognitive behavior therapy.
