ABSTRACT

BACKGROUND: The incidence of liver tumors requiring surgical treatment continues to increase in elderly patients. This study compared the short-term results of robotic liver surgery (RLS) versus open liver surgery (OLS) for liver tumors in elderly patients. METHODS: A prospective database including all patients undergoing liver surgery at Copenhagen University Hospital between July 2019 and July 2022 was managed retrospectively. Short-term surgical outcomes of the two main cohorts (OLS and RLS) and subgroups were compared using propensity score matching (PSM) in elderly patients (age ≥ 70 years) with liver tumors. RESULTS: A total of 42 matched patients from each group were investigated: the RLS group had significantly larger tumor diameters, less blood loss (821.2 vs. 155.2 mL, p < .001), and shorter hospital stays (6.6 vs. 3.4 days, p < .001). Overall morbidity was comparable, while operative times were longer in the RLS group. The advantages observed with the robotic approach were replicated in the subgroup of minor liver resections. CONCLUSIONS: In patients ≥70 years, RLS for liver tumors results in significantly less blood loss and shorter hospital stays than OLS. RLS, especially minor liver resection, is safe and feasible in elderly patients with liver tumors.

ABSTRACT

BACKGROUND/PURPOSE: Few clinically useful biomarkers are known to predict prognosis in patients with hepatocellular carcinoma (HCC). The aim of this study was to investigate the correlation between PPAR activity and ALDH7A1 expression and their prognostic significance using RNA sequencing in patients undergoing liver resection for HCC. METHODS: We included patients undergoing liver resection for HCC at a tertiary referral center for hepato-pancreato-biliary surgery between May 2014 and January 2018. PPAR activity and ALDH7A1 expression were evaluated by RNA sequencing and correlated with overall survival, recurrence and histological features. RESULTS: We included 52 patients with a median follow-up of 20.9 months, predominantly males (88.5%) with a single tumor (84.6%) in a non-cirrhotic liver (73.1%). Three-year overall survival was 48.6% in patients with a specific PPAR target gene expression profile (cancer cluster 3) compared with 81.7% in controls (P = .04, Log-rank test). This remained significant (odds ratio 14.02, 95% confidence interval 1.92-102.22, P = .009) when adjusted for age, cirrhosis, microvascular invasion, number of tumors and free resection margins. ALDH7A1 expression was not correlated with PPAR or any outcomes. CONCLUSION: PPAR activity in a subset of tumor samples was associated with reduced overall survival indicating that PPAR may be a valuable prognostic biomarker.

ABSTRACT

BACKGROUND: Patients with perihilar cholangiocarcinoma and gallbladder cancer extending into the hilum often present with jaundice and a small future liver remnant (FLR). If resectable, preoperative biliary drainage and portal vein embolization (PVE) are indicated. Classically, these measures have been performed sequentially, separated by 4-6 weeks. PURPOSE: To report on a new regime where percutaneous transhepatic biliary drainage (PTBD) and PVE are performed simultaneously, shortening the preoperative process. MATERIAL AND METHODS: Six patients were treated with concurrent PTBD and PVE under general anesthesia. RESULTS: Surgical exploration followed the combined procedure after 35 days (range, 28-51 days). The FLR ratio increased from 22% to 32%. Three patients developed cholangitis after the procedure. CONCLUSION: The combined approach of PTBD and PVE seems feasible, but more studies on morbidity are warranted.
