Hepatitis B virus(HBV)reactivation(HBVr)represents a severe and potentially life-threatening condition,and preventive measures are available through blood test screening or prophylactic therapy *** assessment of HBVr traditionally considers factors such as HBV profile,including hepatitis B surface antigen(HBsAg)and antibody to hepatitis B core antigen,along with type of medication(chemotherapy;immunomodulants).Nevertheless,consideration of possible patient’s underlying tumor and the specific malignancy type(solid or hematologic)plays a crucial role and needs to be assessed for decision-making process.

Intraoperative ultrasonography(IOUS)in hepatobiliary surgery is well known as an essential tool for radical and safe hepatectomies,allowing to perform parenchymal sparing surgery and,as consequence,to expand the surgical indications for patients otherwise considered ***,since many years,despite its effectiveness in the study of vascular anatomy of the liver,the gold standard for the assessment of biliary anatomy during surgery is intraoperative cholangiography(IOC),which is used for the validation of preoperative imaging as well as for guiding reconstruction in case of bile duct injury or resection.

The rationale of the performance of anatomic resection(AR)of the liver in case of hepatocellular carcinoma(HCC)is the removal of portal pedicle feeding the tumor because of the tumor’s tendency to invade the portal veins(1).This technical approach is expected to be effective from an oncological perspective for a disease such as HCC,which is associated with a high rate of intrahepatic recurrence(2,3).In the eighties,Makuuchi et *** the systematic subsegmentectomy(4)reporting excellent results(5),and later some other authors reported new techniques to identify the portal territory of a given HCC and perform a true AR of the liver(5-7).

Objective: To analyze data available in the literature regarding a possible prognostic value of the platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) in prostate cancer (PCa) patients stratified in non-metastatic and metastatic ***: A literature search process was performed following the Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines. In our meta-analysis, the pooled event rate estimated and the pooled hazard ratio were calculated using a random effect ***: Forty-two articles were selected for our analysis. The pooled risk difference for non-organ confined PCa between high and low NLR cases was 0.06 (95% confidence interval [CI]: −0.03-0.15) and between high and low PLR cases increased to 0.30 (95% CI: 0.16-0.43). In non-metastatic PCa cases, the pooled hazard ratio for overall mortality between high and low NLR was 1.33 (95% CI: 0.78-1.88) and between high and low PLR was 1.47 (95% CI: 0.91-2.03), whereas in metastatic PCa cases, between high and low NLR was 1.79 (95% CI: 1.44-2.13) and between high and low PLR was 1.05 (95% CI: 0.87-1.24).Conclusion: The prognostic values of NLR and PLR in terms of PCa characteristics and responses after treatment show a high level of heterogeneity of results among studies. These two ratios can represent the inflammatory and immunity status of the patient related to several conditions. A higher predictive value is related to a high NLR in terms of risk for overall mortality in metastatic PCa cases under systemic treatments.
