Abstract

Background

Not all patients with resectable colorectal liver metastases (CLM) benefit from liver resection (LR); only patients with disease progression during chemotherapy are excluded from surgery.

Objective

This study was performed to determine whether tumor behavior (stable disease/progression) from the end of chemotherapy to LR impacts prognosis.

Methods

Patients undergoing LR after tumor response or stabilization during chemotherapy were considered. Overall, 128 patients who underwent examination by two imaging modalities (computed tomography/magnetic resonance imaging) after chemotherapy with a > 3-week interval between the two imaging modalities were analyzed. Any variation in CLM size was registered. Tumor progression was defined according to the response evaluation criteria in solid tumors (RECIST) criteria.

Results

Among 128 patients with stable disease or partial response to preoperative chemotherapy, 32 (25%) developed disease progression in the chemotherapy to LR interval, with a disease progression rate of 17% when this interval was < 8 weeks. Survival was lower among patients with progression than those with stable disease [3-year overall survival (OS) 23.0 vs. 52.4%, and recurrence-free survival (RFS) 6.3% vs. 21.6%; p < 0.001]. Survival was extremely poor in patients with early progression (< 8 weeks) (0.0% 2-year OS, 12.5% 6-month RFS). Disease progression in the chemotherapy to LR interval was an independent negative prognostic factor for OS and RFS [hazard ratio 3.144 and 2.350, respectively; p < 0.001].

Conclusions

Early disease progression in the chemotherapy to LR interval occurred in approximately 15% of patients and was associated with extremely poor survival. Even if these data require validation, the risk for early disease progression after chemotherapy should be considered, and, if progression is evident, the indication for surgery should be cautiously evaluated.

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.
