Abstract

Background

Osteopenia, which exhibits low bone mineral density (BMD), has been linked to sarcopenia and recently reported as a prognostic factor in various cancers. However, the prognostic significance of osteopenia in esophageal cancer remains unclear. Hence, this study aimed to clarify the impact of osteopenia on the prognosis of patients undergoing esophagectomy for esophageal cancer.

Methods

We included 229 patients who underwent esophagectomy. BMD was calculated as the average pixel density (Hounsfield unit) within a circle in midvertebral core at the 11th thoracic vertebra on preoperative computed tomography. We then divided the patients into the Osteopenia group (n = 159) and the Non-Osteopenia group (n = 70) according to the optimal cutoff value obtained from the receiver operating characteristic curve. Their clinicopathological data, prognosis, and recurrence were analyzed.

Results

The mean age was significantly older in the Osteopenia group (p = 0.047). The Osteopenia group had significantly worse overall survival (OS) and relapse-free survival (RFS) than the Non-Osteopenia group (p = 0.001 and p = 0.012, respectively). Multivariate analysis revealed osteopenia was an independent prognostic factor for OS (p < 0.001; hazard ratio [HR], 2.243; 95% confidence interval [CI], 1.422–3.538) and RFS (p = 0.008; HR, 1.739; 95% CI, 1.154–2.620). In logistic regression model, advanced age and cStage III-IV were independent risk factors for preoperative osteopenia.

Conclusions

Preoperative osteopenia is associated with poor survival and recurrence in patients undergoing esophagectomy for esophageal 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.

S2e-Leitlinie „Distale Radiusfraktur“

Radiusfraktur BDC Leitlinien Webinare
CME: 2 Punkte

Das Webinar beschäftigt sich mit Fragen und Antworten zu Diagnostik und Klassifikation sowie Möglichkeiten des Ausschlusses von Zusatzverletzungen. Die Referenten erläutern, welche Frakturen konservativ behandelt werden können und wie. Das Webinar beantwortet die Frage nach aktuellen operativen Therapiekonzepten: Welcher Zugang, welches Osteosynthesematerial? Auf was muss bei der Nachbehandlung der distalen Radiusfraktur geachtet werden?
