EAU guidelines on prostate cancer

OBJECTIVES: To develop clinical guidelines for the management of patients with prostate cancer. METHODS: Guidelines were compiled by a working panel based on current literature following a literature review using MEDLINE. Already published structured analysis from national and international guidelines was used, and panel consensus was employed when literature evidence was absent or of poor quality. RESULTS: The full text of the guidelines is available through the EAU Central Office and the EAU website (www.uroweb.org). This article summarizes the main conclusions from the guidelines concerning the diagnosis and staging, treatment and follow-up of patients with prostate cancer. The diagnosis of prostate cancer should be based on histopathological or cytological examinations. N- and M-staging may be omitted in selected patients with a low serum prostate-specific antigen due to low risk of metastasis. Active treatment is warranted in most stages of prostate cancer but active monitoring is recommended for elderly patients with early stage tumours and is still optional in some other situations. Follow-up is based on a disease-specific history, serum-prostate-specific antigen supplemented by a digital rectal examination. Routine imaging is not necessary in asymptomatic patients. CONCLUSIONS: Prostate cancer is one of the most common malignancies in men. These guidelines have been drawn up to provide support in the management of this large group of patients.     

Cancer of the prostate: influence of nutritional factors. Vitamins, antioxidants and trace elements

CANCER OF THE PROSTATE AND VITAMINS: Four vitamins have been studied, vitamins A, E, D and C. the results of these studies have been contradictory. Vitamin A and vitamin E would have a protective effect. ANTIOXIDANTS: Carotenes have an activity similar to that of vitamin A. Beta-carotene was positively associated with risk of cancer of the prostate in one study while two others were unable to demonstrate any relationship. Lycopene, the red color in fruits and vegetables, particularly tomatoes, would contribute to a lower risk of prostate cancer. TRACE ELEMENTS: Cadmium would increase the risk of cancer while selenium would have a protective effect. However studies concerning selenium carry certain methodological biases.     

Results of retroperitoneal laparoscopic radical nephrectomy

PURPOSE: To analyze the retroperitoneal approach to laparoscopic radical nephrectomy in terms of feasibility, safety, morbidity, and cancer control. PATIENTS AND METHODS: We reviewed the records of 50 consecutive patients with renal cancer underwent radical nephrectomy via the retroperitoneal laparoscopic approach from 1995 through 1999. RESULTS: The mean operative time was 139 minutes (range 60-330 minutes) with a mean of 149.78-mL operative blood loss (0-1500 mL). The mean renal size was 100 mm (70-150 mm) with a mean tumor size of 38.6 mm (20-90 mm). The postoperative hospital was 6 days (2-13 days). Three open conversions were necessary: one for laparoscopically uncontrolled bleeding and two because obesity interfered with surgery. We noted two major complication and two minor complications. Two disease progression have been noted to date. One patient with a pT3 grade 2 renal-cell carcinoma had a local recurrence with liver metastasis 9 months after the procedure and died 19.7 months after radical nephrectomy. Another patient with a pT3aN+M+ cancer died 23.1 months after the procedure. CONCLUSION: Retroperitoneal laparoscopic nephrectomy for kidney cancer requires further assessment. It seems to have several advantages over open radical nephrectomy and to be effective and safe for small (<50-mm) renal tumors.     

Combined heart and kidney transplantation using the same donor

A 45-year-old man received a combined heart and kidney transplant provided by the same donor. The patient was in the terminal stage of renal failure and was submitted to 3 sessions of haemodialysis per week for 2 years before transplantation. A dilated cardiomyopathy with severe impairment of left ventricular (LV) function was discovered, precluding renal transplantation alone. In the postoperative course, a cardiac rejection episode was detected by echocardiography and documented by endomyocardial biopsy; no simultaneous rejection of the kidney could be detected. The patient was discharged after 2 months, and he resumed a normal and active life. The specific problems raised by the management of such multi-organ transplantation are briefly reviewed.
