Abstract

Background

The adverse oncological effect of portal vein embolization (PVE) in patients with colorectal liver metastases (CLM) remains controversial. This study was designed to evaluate the effect of PVE on change of tumor characteristics using tumor specimens obtained from sequential hepatectomy before and after PVE.

Methods

Between December 1996 and April 2009, among 55 patients who achieved two-stage hepatectomy (TSH) combined with PVE, 39 had available cancer tissue blocks from both the first- and second-stage hepatectomy and constituted the study population. The immunohistochemistry of Ki67 and Bcl-2 before and after PVE was performed. Biomarker expressions and clinicopathological variables were assessed and their impact on recurrence was analyzed.

Results

Whereas tumor volume and carcinoembryonic serum level significantly increased after PVE, the expression of Ki67 and Bcl-2 remained similar before and after PVE. The Bcl-2 ratio (expressed as Bcl-2 after PVE over Bcl-2 before PVE) was an independent prognostic factor for recurrence-free survival (P = 0.030). Patients with Bcl-2 ratio ≤1 had a significantly longer median recurrence-free survival compared with those with Bcl-2 ratio >1 receiving or not receiving adjuvant chemotherapy (24.8 months versus 8.9 or 5.8 months, respectively).

Conclusion

Bcl-2 ratio may predict early recurrence and identify patients who do not require postoperative chemotherapy in patients undergoing TSH with PVE for CLM.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

Karpaltunnelsyndrom BDC Leitlinien Webinare
CME: 2 Punkte

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.
