Radiation therapy after radical surgery in prostate cancer.

Radiation therapy plays a key role in the treatment of prostate cancer on its own. For higher risk diseases, the risk of recurrence following single modality therapy increases and a combination of treatment modalities may be necessary to achieve optimal results. We review clinical outcomes of adjuvant and salvage radiotherapy following radical prostatectomy, including disease-free survival, cancer-specific survival and overall survival.

[Xanthogranulomatous pyelonephritis: clinical, radiological and pathologic characteristics].

Objectives: Xanthogranulomatous pyelonephritis is an atypical chronic infection which simulates a malignant renal neoplasia, definitive diagnosis of which is obtained by pathologic study after surgical removal. In this paper we analyze our experience and compare it to that reported on the literature.

Methods: We performed a retrospective study of cases of xanthogranulomatous pyelonephritis diagnosed in the period from January 1945 to December 2000 at the Institute of Neoplastic Diseases, analyzing clinical, radiological, and surgical features documented in the medical records.
