Kurative Therapie

Neue Erkenntnisse über die Anatomie und Funktion der Leber haben dazu geführt, dass heute die chirurgische Resektion die Therapie der Wahl bei Lebermetastasen geworden ist. Obschon Lebermetastasen ein fortgeschrittenes Tumorstadium bedeuten, werden infolge besserer Kenntnisse der Karzinogenese (Mikrometastasen etc.) sowie der prognostischen Risikofaktoren erwiesenermassen die besten Langzeitresultate durch die chirurgische Resektion erzielt. In dieser Studie wurden die Ergebnisse von 109 Resektionen von kolorektalen sowie nicht kolorektalen Lebermetastasen an unserer Klinik während eines Zeitraumes von 59 Monaten zusammengefasst. Vier verschiedene Operationsverfahren (formelle Hemihepatektomie vs Segmentresektion vs atypische Resektion vs Biopsie) wurden untersucht. Die Einhaltung eines Resektionsabstandes von mindestens 10 mm wurde bei Resektionen immer angestrebt. Die kumulierte Morbidität aller Operationsverfahren zusammen betrug 23%. Obwohl die Morbidität bei ausgedehnten Resektionen höher war (Encephalopathie 16% vs 2.3% bei der Segmentresektion, Leberinsuffizienz 23% vs 4.7%), war das Langzeitüberleben gegenüber den limitierten Resektionsverfahren verbessert. Die 60-Tage Mortalität lag bei 2.7%. Patienten nach Resektion von kolorektalen Lebermetastasen hatten eine höhere Ueberlebensrate als diejenigen nach Resektion nicht kolorektaler Metastasen. Unsere Resultate zeigen, dass die Leberresektion heutzutage unter Einhaltung der anatomischen sowie funktionellen Grenzen (inkl. eines adäquaten Resektionsrandes) die einzige, potentiell kurative Therapie von Lebermetastasen darstellt. Trotz erhöhter perioperativer Morbidität ist die ausgedehnte formelle Resektion den limitierten Operationsverfahren bezüglich Langzeitüberleben überlegen. Ein Grund dafür ist die erhöhte Wahrscheinlichkeit einer Mitresektion von präoperativ nicht detektierbaren lokalen Mikrometastasen.

Introduction: Radical liver resection is the only method for the treatment of patients with colorectal liver metastases (CLM); however, only 20–30% of patients with CLMs can be radically treated. Radiofrequency ablation (RFA) is one of the possible methods of palliative treatment in such patients. Methods: RFA was performed in 381 patients with CLMs between 01 Jan 2001 and 31 Dec 2018. The mean age of the patients was 65.2±8.7 years. The male to female ratio was 2:1. Open laparotomy was done in 238 (62.5%) patients and the CT-navigated transcutaneous approach was used in 143 (37.5%) patients. CLMs <5 cm (usually <3 cm) in diameter were the indication for RFA. We used RFA as the only method in 334 (87.6%) patients; RFA in combination with resection was used in 36 (9.4%), and with multi-stage resection in 11 (3%) patients. We performed RFA in a solitary CLM in 170 (44.6%) patients, and in 2−5 CLMs in 211 (55.6%) patients. We performed computed tomography in each patient 48 hours after procedure. Results: The 30-day postoperative mortality was zero. Complications were present in 4.8% of transcutaneous and in 14.2% of open procedures, respectively, in the 30-day postoperative period. One-, 3-, 5- and 10-year overall survival rates were 94.8, 66.8, 43.9 and 16.6%, respectively, in patients undergoing RFA, and 90.6, 69.1, 52.8 and 39.2%, respectively, in patients with liver resections. Disease free survival was 63.2, 30.1, 18.4 and 13.1%, respectively, in the same patients after RFA, and 71.1, 33.3, 22.8 and 15.5%, respectively, after liver resections. Conclusion: RFA is a palliative thermal ablation method, which is one of therapeutic options in patients with radically non-resectable CLMs. RFA is useful especially in a non-resectable, or resectable (but for the price of large liver resection) solitary CLM <3 cm in diameter and in CLM relapses. RFA is also part of multi-stage liver procedures.

Medical Histories

Background: Hepatectomies are mostly performed for the treatment of hepatic benign or malignant neoplasms, intrahepatic gallstones, or parasitic cysts of the liver. The most common malignant neoplasms of the liver are metastases from colorectal cancer. Anatomic liver resection involves two or more hepatic segments, while non-anatomic liver resection involves resection of the metastases with a margin of uninvolved tissue. The aim of this manuscript was to show results of hepatectomies performed at the Oncology Institute of Vojvodina. Methods: We performed 133 liver resections from January 1997 to December 2013. Clinical and histopathological data were obtained from operative protocols, histopathological reports, and patients? medical histories. Results: We did 80 metastasectomies, 51 segmentectomies, and 18 radiofrequent ablations (RFA). Average number of colorectal cancer metastases was 1.67 per patient. We also made 10 left hepatectomies. In all cases, we made non-anatomic resections. Conclusion: Decision about anatomic versus non-anatomic resections for colorectal metastasis and primary liver tumors should be made before surgical exploration. Preservation of liver parenchyma is important with respect to liver failure and postoperative chemotherapy treatment.
