Abstract

Background

The influence of margin status on long-term outcome of patients undergoing liver resection for intrahepatic cholangiocarcinoma (ICC) remains controversial. We sought to study the impact of surgical tumor margin status on recurrence-free survival (RFS) and overall survival (OS) of patients undergoing resection for ICC.

Methods

From a multi-institutional database, 583 patients who underwent hepatic resection for ICC were identified. Demographics data, operative details, pathologic margin status, and long-term outcomes were collected and analyzed.

Results

Margin status was positive (R1) in 95 (17.8 %) patients; among patients who underwent an R0 resection (80.9 %), margin width was negative by 1–4 mm in 166 (31.0 %) patients, 5–9 mm in 100 (18.7 %) patients, and ≥1 cm in 174 (32.5 %) patients. Overall, 379 (65.0 %) patients had a recurrence: 61.5 % intrahepatic, 13.5 % extrahepatic, and 25.0 % both intra- and extrahepatic. Median and 5-year RFS and OS was 10.0 months and 9.2 %, and 26.4 months and 23.0 %, respectively. Patients who had an R1 resection had a higher risk of recurrence (hazard ratio [HR] 1.61, 95 % CI 1.15–2.27; p = 0.01) and shorter OS (HR 1.54, 95 % CI 1.12–2.11). Among patients with an R0 resection, margin width was also associated with RFS (1–4 mm: HR 1.32, 95 % CI 0.98–1.78 vs. 5–9 mm: HR 1.21, 95 % CI 0.89–1.66) and OS (1–4 mm: HR 1.95, 95 % CI 0.45–2.63 vs. 5–9 mm: HR 1.21, 95 % CI 0.88–1.68) (referent ≥1 cm; both p ≤ 0.002). Margin status and width remain independently associated with RFS and OS on multivariable analyses.

Conclusions

For patients undergoing resection of ICC, R1 margin status was associated with an inferior long-term outcome. Moreover, there was an incremental worsening RFS and OS as margin width decreased.

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.
