Hepatocellular carcinoma surveillance: an open question

Hepatobiliary Surgery and Nutrition 2019年第4期8卷 431-432页

作者： Maurizio Biselli Francesca Garuti Andrea Neri Department of Medical and Surgical Sciences Semeiotica Medica Alma Mater Studiorum University of Bologna Bologna Italy

We were very interested to read the study recently published in Gastroenterology by Moon et al. (1). Performed as a case-control study within the US Veterans Affairs health care system, the study aimed to assess the association between screening for hepatocellular carcinoma (HCC) and cancer related-mortality in patients with cirrhosis. The authors did not find any evidence that screening patients with cirrhosis by abdominal ultrasound (US) or alpha-fetoprotein (AFP) levels decreases HCC-related mortality.

Retrospective descriptive analysis of the physiological kinetics of prostate-specific antigen in men older than 75 years

引用

Asian Journal of Andrology 2009年第4期11卷 493-497页

作者： Maria Chiara Sighinolfi Salvatore Micali Stefano De Stefani Arrigo Cicero Filippo Cianci Marco Giacometti Giampaolo Bianchi Department of Urology University of Modena and Reggio Emilia Modena 41100 Italy Clinical Medicine and Applied Biotechnology Department Alma Mater Studiorum University of Bologna Bologna 40100 Italy

Several studies have compared prostate-specific antigen （PSA） kinetics in men with and without cancer, but there has been no adequate analysis of the longitudinal variation in PSA. The aim of this study was to assess the fluctuations in PSA in a cohort of elderly men in an attempt to define a physiological pattern of PSA kinetics. We searched a specific cohort of patients aged 〉 75 years and with PSA value 〈 2.0 ng mL^-1. A history of all PSA values over the past 10 years was compiled for each patient to create a database of patients fitting the following criteria：（1） minimum of five PSA measurements, （2） over at least 5 years. Exclusion criteria were：（1） PSA 〈 0.2 ng mL^-1 at each measurement and （2） having had more than one PSA test per year. In all, 1 327 patients （mean age： 78.52 years） fit the inclusion criteria. The mean variation from the first to the last PSA test was 0.05 ± 0.43, with a mean follow-up of 6.79 ± 1.71 years. Over the same period, the mean fluctuation from the lowest to the highest PSA value was 0.04 ± 0.55 （P = 0.925）. The mean annual PSA velocity （PSAV） was calculated by dividing the mean variation from the first to the last PSA test by the number of years of observation for each patient and was set at 0.0104 ± 0.1050. Concluding, in a large-scale cohort of elderly individuals considered healthy and evaluated for a considerable follow-up, the average annual PSAV as well as the average fluctuation from the lowest to the highest PSA value are insignificant.
