Changes in patterns of practice for prostate cancer radiotherapy in Italy 1995-2003. A survey of the Prostate Cancer Study Group of the Italian Radiation Oncology Society.

Aims and background. In 2002, a survey including 1759 patients treated from 1980 to 1998 established a "benchmark" Italian data source for prostate cancer radiotherapy. This report updates the previous one. Methods. Data on clinical management and outcomes of 3001 patients treated in 15 centers from 1999 through 2003 were analyzed and compared with those of the previous survey. Results. Significant differences in clinical management (-10% had abdominal ma-gnetic resonance imaging; +26% received ≥70 Gy, +48% conformal radiotherapy, -20% pelvic radiotherapy) and in G3-4 toxicity rates (-3.8%) were recorded. Actuarial 5-year overall, disease-specific, clinical relapse-free, and biochemical relapse-free survival rates were 88%, 96%, 96% and 88%, respectively. At multivariate analysis, D'Amico risk categories significantly impacted on all the outcomes; higher radiotherapy doses were significantly related with better overall survival rates, and a similar trend was evident for disease-specific and biochemical relapse-free survival; cumulative probability of 5-year late G1-4 toxicity was 24.8% and was significantly related to higher radiotherapy doses (P <0.001). Conclusions. The changing patterns of practice described seem related to an improvement in efficacy and safety of radiotherapy for prostate cancer. However, the impact of the new radiotherapy techniques should be prospectively evaluated.

Hypertension portate et infection par le VIH [Portal hypertension and HIV infection]

In the era of antiretroviral therapies, the outcome of patients with chronic HIV infection has considerably changed and their prolonged survival allows the development of chronic liver diseases as a major cause of mortality. Although viral hepatitis, alcoholic and non alcoholic steatohepatitis account forthe majority of chronic liver damage in these patients, there is a growing number of cases with unexplained liver disease, many of which are associated with clinical manifestations of portal hypertension. Inthissituation, nodularregenerative hyperplasia is a frequent finding, characterized at histology by the presence of a nodular architecture in the absence of significant fibrosis, resulting from progressive obliteration of small portal veins. This article describes the clinical presentation, diagnostic aspects, pathogenic mechanisms, as well as the management of this emergent non cirrhotic liver disease in HIV-infected patients.
