Abstract

Background

Undifferentiated pleomorphic sarcoma/NOS (not otherwise specified; former pleomorphic and storiform MFH) of the extremities is a common malignant soft tissue tumor in adults. The objective of this study is to determine prognostic factors for the outcome after surgical treatment with respect to the recent developments in classification.

Methods

From 1996 to 2004, 140 undifferentiated pleomorphic sarcomas/NOS were identified out of 1,200 soft tissue sarcomas of the extremities that were treated at our institution and recorded in a prospective database. Overall survival (OS) and isolated local recurrence (ILR) were determined by Kaplan–Meier analysis. All tumors were retrospectively analyzed regarding prognostic factors of the disease, including patient’s background (primary or recurrent), histological grade (G2/G3), adjuvant chemotherapy and radiotherapy, size (T1–2) and depth of the tumor, and surgical margins (R0, R1, R2).

Results

In 123 patients, a wide resection was performed (limb-sparing surgery). In nine patients, an amputation was necessary. The overall 5-year survival rate was 72% (median follow up: 52 months). There was a significant difference between the group presenting with primary tumors (5-year survival: 84%, p < 0.05) and recurrent tumors (5-year survival: 62%, p < 0.05). Isolated local recurrence occurred in 36 patients.

Conclusions

In terms of OS and ILR, primary or recurrence, negative surgical margins, size and grading had a highly significant influence, whereas the site of surgery and adjuvant chemotherapy, adjuvant radiation and tumor depth did not. Prognosis for patients with undifferentiated pleomorphic sarcoma of the extremities depends predominantly on adequate wide resection of the primary tumor.

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.
