Endobronchial brachytherapy in combination with external beam irradiation in obstructing malignant bronchial tumors.

Endobronchial brachytherapy is commonly used in the palliative management of malignant airway obstructions. In the present study, we describe the results of brachytherapy (mean dose of 18 Gy), used in combination with external beam irradiation (mean dose of 50 Gy) in 30 patients who had primary bronchogenic carcinoma of the lung. The extent of airway obstruction was determined according to symptoms and by bronchoscopy.

[Non-metastatic prostate cancer treated with exclusive radiotherapy: prognosis of patients according to lymph node radiologic or surgical assessment method. Multivariate retrospective analysis].

Purpose: To compare retrospectively the outcome of localized prostate cancers treated by curative external radiotherapy in which the negative lymphatic status was either surgically or radiologically assessed.

Methods And Materials: From January 1986 to December 1995, 112 patients with localized prostate cancers were found to have no evidence of lymphatic disease in the pelvis. N0 status was assessed either surgically (61 patients, group pN-) or after a CT scan procedure (51 patients, group cN0).
