Background: The utility of pre- and post-operative alpha-fetoprotein (AFP) and des-gamma (γ)-carboxy prothrombin (DCP) expression patterns and their dynamic changes as predictors of the outcome of hepatic resection for hepatocellular carcinoma (HCC) has yet to be well elucidated.
Methods: From a multicenter database, AFP and DCP data during the week prior to surgery and the first post-discharge outpatient visit (within 1-2 months after surgery) were collected from patients with HCC who underwent hepatectomy. AFP-DCP expression patterns were categorized according to the number of positive tumor markers (AFP ≥ 20ng/mL, DCP ≥ 40mAU/mL), including double-negative, single-positive, and double-positive.
Background: This study evaluates the efficacy of alpha-fetoprotein (AFP) response as a surrogate marker for determining recurrence-free survival (RFS) in patients with unresectable hepatocellular carcinoma (uHCC) who undergo salvage hepatectomy following conversion therapy with tyrosine kinase inhibitor (TKI) and anti-PD-1 antibody-based regimen.
Methods: This multicenter retrospective study included 74 patients with uHCC and positive AFP (>20 ng/mL) at diagnosis, who underwent salvage hepatectomy after treatment with TKIs and anti-PD-1 antibody-based regimens. The association between AFP response-defined as a ≥ 80% decrease in final AFP levels before salvage hepatectomy from diagnosis-and RFS post-hepatectomy was investigated.
Background: Routine clinical staging for hepatocellular carcinoma (HCC) incorporates liver function, general health, and tumor morphology. Further refinement of prognostic assessments and treatment decisions may benefit from the inclusion of tumor biological marker alpha-fetoprotein (AFP) and systemic inflammation indicator C-reactive protein (CRP).
Methods: Data from a multicenter cohort of 2770 HCC patients undergoing hepatectomy were analyzed.
Background: The efficacy and safety of tyrosine kinase inhibitors (TKIs) combined with anti-PD-1 antibodies (α-PD-1) in advanced hepatocellular carcinoma (HCC) with high hepatitis B virus (HBV) DNA levels (>500 IU/mL) remain unclear.
Methods: We retrospectively assessed patients from seven medical institutions diagnosed with HBV-related HCC, undergoing treatment with TKIs and α-PD-1 in conjunction with antiviral therapies. Based on HBV-DNA levels, patients were categorized into either high (HHBV-DNA, >500 IU/mL) or low HBV-DNA (LHBV-DNA, ≤500 IU/mL) cohorts Propensity score matching (PSM) was used to minimize baseline imbalance between groups.
Background: To assess the perioperative safety, oncological outcomes, and determinants influencing the oncological outcomes of salvage liver resection for initially unresectable hepatocellular carcinoma (HCC) rendered resectable through transarterial chemoembolization (TACE) combined with tyrosine kinase inhibitors (TKIs) and anti-PD-1 antibodies (α-PD-1).
Methods: We retrospectively reviewed data from 83 consecutive patients across six tertiary hospitals who underwent salvage liver resection for initially unresectable HCC following conversion by TACE combined with TKIs and α-PD-1, emphasizing perioperative and oncological outcomes. Multivariate Cox regression analysis was employed to discern independent risk factors for postoperative recurrence-free survival (RFS).

Low-altitude unmanned aerial vehicles (UAV) remote sensing system overcomes the deficiencies of space and aerial remote sensing system in resolution, revisit period, cloud cover and cost, which provides a novel method for ecological research on mesoscale. This study introduced the composition of UAV remote sensing system, reviewed its applications in species, population, community and ecosystem ecology research. Challenges and opportunities of UAV ecology were identified to direct future research.
