Chronic hepatitis C is the main cause of death in patients with end-stage liver disease. Prognosis depends on the increase of fibrosis, whose progression is twice as rapid in men as in women. Aim of the study was to evaluate the effects of reproductive stage on fibrosis severity in women and to compare these findings with age-matched men. A retrospective study of 710 consecutive patients with biopsy-proven chronic hepatitis C was conducted, using data from a clinical database of two tertiary Italian care centers. Four age-matched groups of men served as controls. Data about demographics, biochemistry, liver biopsy and ultrasonography were analyzed. Contributing factors were assessed by multivariate logistic regression analysis. Liver fibrosis was more advanced in the early menopausal than in the fully reproductive (P<0.0001) or premenopausal (P = 0.042) group. Late menopausal women had higher liver fibrosis compared with the other groups (fully reproductive, P<0.0001; premenopausal, P = <0.0001; early menopausal, P = 0.052). Multivariate analyses showed that male sex was independently associated with more severe fibrosis in the groups corresponding to premenopausal (P = 0.048) and early menopausal (P = 0.004) but not late menopausal pairs. In women, estradiol/testosterone ratio decreased markedly in early (vs. reproductive age: P = 0.002 and vs. premenopausal: P<0.0001) and late menopause (vs. reproductive age: P = 0.001; vs. premenopausal: P<0.0001). In men age-matched with menopausal women, estradiol/testosterone ratio instead increased (reproductive age group vs. early: P = 0.002 and vs. late M: P = 0.001). The severity of fibrosis in women worsens in parallel with increasing estrogen deprivation and estradiol/testosterone ratio decrease. Our data provide evidence why fibrosis progression is discontinuous in women and more linear and severe in men, in whom aging-associated estradiol/testosterone ratio increase occurs too late to noticeably influence the inflammatory process leading to fibrosis.

Purpose: Several scoring systems to evaluate patients with hepatocellular carcinoma (HCC) exist. A good scoring system should provide information on prognosis and guide therapeutic decisions. The presence of variant liver estrogen receptor (ER) transcripts in the tumor has been shown to be the strongest negative predictor of survival in HCC. The aim of this study was to compare the predictive value of the commonly applied clinical scoring systems for survival of patients with HCC with that of the evaluation of ER in patients with HCC (molecular scoring system). Materials and Methods: HCC was staged according to the Okuda classification, Barcelona Clinic Liver Cancer classification, Italian classification system (CLIP), French classification, and ER status in 96 patients. Analysis of survival was performed according to the Kaplan-Maier test and was made for each classification system and ER. A comparison between classifications was made by univariate and multivariate analysis. Results: Among the clinical classification systems, only the CLIP was able to identify patient populations with good, intermediate, and poor prognosis. On multivariate analysis, ER classification was shown to be the best predictive classification for survival of patients with HCC (P <.0001). This difference was the result of a better allocation of patients with ominous prognosis (variant ER) having nevertheless good clinical score. Conclusion: The evaluation of the presence of wild-type or variant ER transcripts in the tumor is the best predictor of survival in patients with HCC. Its accuracy in discriminating patients with good or unfavorable prognosis is significantly greater than that of the commonly used scoring systems for the staging of HCC.

Background: Laparoscopic splenectomy is accepted as a safe approach in the surgical treatment of blood disorders worldwide. Compared with the laparotomic technique, it is associated with a lower risk of intraoperative bleeding, less postoperative pain, and faster discharge times. The advent of robotic surgery (RS) has changed the concept of minimally invasive surgery because, in addition to allowing a three-dimensional view, it permits greater freedom of movement and higher levels of accuracy than laparoscopic surgery (LS). The aim of this study was to comparatively evaluate whether RS presents advantages over LS in spleen surgery. Methods: In two Surgical Units with experience in laparoscopic splenectomy, over a 7-year period, two groups of 45 patients underwent LS and RS. The two groups were well matched for demographic characteristics, indications, and spleen size. Results: No statistically significant differences were found regarding intraoperative blood loss, conversion rate to laparotomy, food intake, drain removal, postoperative complications, and median time to discharge. On the contrary, statistically increased differences were observed in median operative time and costs. In both groups, the transfusion and mortality rate was 0%. At the 6-month follow-up no surgical complications were observed. Conclusions: Although RS offers a three-dimensional view, greater freedom of movement, and higher levels of accuracy, it is associated with longer operative times and higher costs. It can consequently be concluded that with the intrinsic limits of the study design used, at the current time, RS does not have any significant advantage over LS in splenectomy.
