Does age influence early and late tumor-related outcome for bronchogenic carcinoma?
Perioperative risk and midterm survival were similar in younger and older patients after surgical resection of bronchogenic carcinoma. We believe that this result is because surgical candidates constitute already a highly selected group of patients. From these data it is not possible to conclude that biologic behavior of lung cancer is more aggressive in younger patients.
Patients with frequent RV pacing and paced QRS duration ≥150 milliseconds should be screened by echocardiogram to assess for PICM. Patients with paced QRS duration <150 milliseconds likely do not require screening, in the absence of heart failure signs or symptoms.
