Carcinoid syndrome impacts long-term outcomes after hepatectomy for small bowel NET liver metastasis- a retrospective single center analysis of 287 patients 1Department of Surgery, Regional Hospital Wiener Neustadt, Austria; 2Department of Surgery, Mayo Clinic, Rochester, MN, USA; 3Department of Surgery, HPB Center, Vienna Health Network, Clinic Favoriten and Sigmund Freud Private University, Vienna, Austria; 4Department of Cardiovascular Medicine, Mayo Clinic, Rochester, MN, USA; 5Division of Medical Oncology, Department of Oncology, Mayo Clinic, Rochester, MN, USA; 6Division of General Surgery, Department of Surgery, University of Toronto, Toronto, Canada Background Liver metastases from LMsbNET can cause carcinoid syndrome (CS), which may be managed with cytoreductive hepatectomy, improving symptom control and survival. Methods From January 2000 to December 2020, patients with CS and LMsbNET (n=154) and non-functional LMsbNET (n=133) underwent cytoreductive hepatectomy. Patient and tumor characteristics, as well as oncological and symptomatic long-term outcomes, were assessed. Results Patients with CS had more (p<0.001) and larger (p<0.001) hepatic metastases, leading to more frequent major hepatectomies (44% vs. 14%; p<0.001). Postoperative morbidity (22% vs. 21%; p=0.925) and 90-day mortality (1% vs. 2%; p=0.666) were similar. Median overall survival (OS) and progression-free survival (PFS) were shorter in CS patients (10.1 vs. 12.5 years, p=0.035 and 1.6 vs. 2.4 years, p=0.015). In a matched subgroup, non-functional LMsbNET patients had longer OS (11.4 vs. 16.7 years, p=0.014). Among patients with long-term follow-up (n=191), 50% of CS patients developed secondary CS, compared to 41% of initially non-functional LMsbNET patients. Secondary CS decreased OS compared to non-functional tumor progression (6.1 vs. 9.4 years from progression, p=0.002) and was associated with carcinoid heart disease (CaHD) in 16% of patients. Multivariable regression identified CS as the strongest liver metastasis-specific factor associated with OS (HR 1.73, p=0.004). Conclusion Cytoreductive hepatectomy provides excellent long-term outcomes for LMsbNET, but concurrent CS is associated with decreased OS and PFS. Secondary CS frequently emerges upon tumor progression, adversely affecting OS and posing a risk for CaHD. Regular monitoring and prompt management of CS may improve survival. 15:55 - 16:00
Sind Pankreasresektionen in einem Patient:innengut über 80 Jahre vertretbar - ein systematischer Review mit Metaanalyse medizinische Universität Graz, Österreich Einleitung/Background Circa 70% der Patient:innen, die mit PDAC diagnostiziert werden, haben das 65. Lebensjahr bereits überschritten, die höchste Inzidenz für PDAC ist sogar bei Patient:innen zwischen dem 75 und dem 85 Lebensjahr beschrieben. In Anbetracht der demographischen Veränderung, werden immer mehr Patient:innen jenseits des 80. Lebensjahres für eine Operation zugewiesen. Die Literatur zu dem Thema erscheint kontroversiell, daher wurde mit einem systematischen Review mit anschliessender Metaana- lyse diese aufgearbeitet. Methoden/Methods Zusammenfassung/Conclusion Das Alter allein scheint kein Ausschlusskriterium für die operative Sanierung eines PDAC’s bei Patient*Innen > 80 dar zu stellen. |
