Abstract

Background

Emerging evidences have gradually revealed the skeletal muscle attenuation (MA) was not only reflected the accumulation of lipids in skeletal muscle but also associated with physiological and pathological states. The aim of this study was to evaluate the impact of MA on the prognosis of pancreatic cancer patients treated with neoadjuvant chemoradiotherapy (NACRT).

Methods

Eighty-three patients with pancreatic cancer who received NACRT were enrolled. Patients were divided according to their Hounsfield units of the skeletal muscle at the third lumbar vertebra in CT. The lower quartile was defined as MA group and the remainder as control group.

Results

There was no significant difference in overall survival between pre-NACRT MA and control groups. In contrast, patients with post-NACRT MA had a significantly poorer prognosis than patients without. The patients in the post-NACRT MA group were significantly older than patients in the control group. There were no significant differences in most clinicopathological and perioperative factors between both groups. However, patients with post-NACRT MA had a longer hospital stay than patients without. Furthermore, the incompletion rate of the proposed adjuvant chemotherapy was significantly higher in the MA group than control. Importantly, multivariate analysis indicated that post-NACRT MA was an independent prognostic factor.

Conclusions

Muscle attenuation may have a significant impact in pancreatic cancer patients treated with multimodal therapy. Therefore, our data may provide new insights into perioperative patient care to improve the prognosis of resectable pancreatic cancer.

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.
