Abstract

Background

This study aimed to assess the prognostic significance of endoluminal ultrasound-defined total length of disease and endoluminal ultrasound defined tumor volume (EDTV) in esophageal cancer. The hypothesis was that endoscopic ultrasound (EUS)-defined total length of disease and EDTV are both significant prognostic indicators and better predictors of outcome than endoscopic tumor length.

Methods

In this study, 174 consecutive patients (median age, 64 years and 128 months) underwent specialist EUS, and the maximum potential EDTV was calculated (πr 2 L, where r is the tumor thickness and L is the total length of disease) including proximal and distal lymph node metastases. Of the 174 patients, 104 underwent surgery (70 had neoadjuvant chemotherapy), 60 underwent definitive chemoradiotherapy, and 10 had palliative therapy.

Results

Survival was related to EUS T stage (p = 0.013), EUS N stage (p = 0.001), EUS M1a stage (p = 0.004), EUS disease length (<8 cm; p = 0.001), and EDTV (all patients <25 cm3, p = 0.001; surgical patients <40 cm3, p = 0.036). Forward conditional multivariate analysis showed three factors to be associated with survival: EUS N stage (hazard ratio [HR], 1.646; 95% confidence interval [CI], 1.041–2.602; p = 0.033), EUS M1a stage (HR, 2.702; 95% CI, 1.069–6.830; p = 0.036), and EDTV (HR, 2.702; 95% CI, 1.069–6.830; p = 0.025). Median and 2-year survival for EDTV <25 cm3 versus >25 cm3 was 43.4 months and 56%, respectively, compared with 23.5 months and 35%.

Conclusions

In this study, EDTV based on total EUS-defined length of disease emerged as a new and important prognostic indicator for patients with esophageal cancer.

In der Notaufnahme wird die Chance, Opfer von häuslicher Gewalt zu identifizieren, von Orthopäden und Orthopädinnen offenbar zu wenig genutzt. Darauf deuten die Ergebnisse einer Fragebogenstudie an der Sahlgrenska-Universität in Schweden hin.

Fehlerkultur in der Medizin – Offenheit zählt!

Darüber reden und aus Fehlern lernen, sollte das Motto in der Medizin lauten. Und zwar nicht nur im Sinne der Patientensicherheit. Eine negative Fehlerkultur kann auch die Behandelnden ernsthaft krank machen, warnt Prof. Dr. Reinhard Strametz. Ein Plädoyer und ein Leitfaden für den offenen Umgang mit kritischen Ereignissen in Medizin und Pflege.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

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.
