Abstract

Purpose

This study aimed to assess the impact of neoadjuvant therapy (NAT) for borderline resectable or locally advanced pancreatic cancer (BR/LAPC) on the American Joint Commission on Cancer (AJCC) nodal status.

Methods

The medical records of BR/LAPC patients who underwent surgery with curative intent were retrospectively reviewed. The nodal status was compared between patients who underwent upfront surgery (UFS) and those who received NAT. Moreover, clinicopathological factors and prognostic factors for overall survival were analyzed.

Results

In all, 200 patients with BR/LAPC, 78 with UFS, and 122 with NAT were enrolled. The nodal status was significantly lower in patients after NAT than after UFS (p = 0.011). A multivariate analysis of overall survival showed that UFS (hazard ratio (HR) 1.61, p = 0.024) and N2 status (HR 2.69, p < 0.001) were independent poor prognostic factors. The median serum carbohydrate antigen (CA) 19–9 level after NAT in N2 patients was 105 U/mL, which was significantly higher than that of patients with N0 (p = 0.004) and N1 (p = 0.008) status.

Conclusion

Patients with BR/LAPC who underwent surgery after NAT had significantly lower N2 status and better prognosis than patients who underwent UFS. Elevated CA19-9 levels after NAT indicated a higher nodal status.

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.
