e14167 Background: Multidisciplinary treatment in patients with colorectal liver metastases (CRLM) is standard in modern oncology. However, for interdisciplinary discussion assessing complimentary disciplines' potential and changes in personal views is crucial. We evaluated experienced medical oncologists' (MO) and surgeons' (SG) assessment of resectability and indication for chemotherapy (CTx) in patients with CRLM. Methods: Thirty patients who underwent R0-resection of CRLM between 2001 and 2011 at our department were selected. Medical history and staging data were presented to MO (n=10) and SG (n=11) in a virtual tumor board (TB1). Standardized blinded TED-voting answers (9 options) included assessment of resectability and the indication for pre- and/or postoperative CTx. The virtual tumor board was followed by training in terms of state-of-the-art lectures on potential of CTx and surgery. Assessment was then repeated in a second virtual tumor board (TB2). Results: 630 (21x30) answers were obtained per tumor board. In TB1 resectability, borderline resectability and definite unresectability were expected in 433, 161 and 36 answers, respectively. Resectability was significantly more often expected by SG (p<0.001). In TB2 57% of answers were different from TB1 (p<0.001). Assessment shifted from borderline resectable to resectable CRLM in 81 of 161 and from unresectable to (borderline) resectable CRLM in 29 of 36 answers (p<0.001). The shift was significant in MO (p=0.012) and SG (p<0.001). Preoperative CTx was significantly more often indicated by MO (p=0.041) and included in 255 answers (44%) in TB1 compared to only 157 answers (27%) in TB2 (p<0.001). With 55% of answers voting for postoperative CTx remained stable in TB1 and TB2 without a significant difference between MO and SG in either TB1 (p=0.099) or TB2 (p=0.353). Conclusions: Resectability and indication for pre- but not postoperative CTx were discrepantly assessed by MO and SG. Training had a strong influence on decision making in MO and SG resulting in a higher rate of patients deemed (borderline) resectable. Furthermore, following training MO and SG opted less often for preoperative CTx.

Chirurgische Entfernung

Die komplette chirurgische Entfernung von Lebermetastasen bietet Patienten nach kolorektalem Karzinom die einzige kurative Chance. Es gibt jedoch eine, anscheinend unbegrenzte, Anzahl an Parametern, die die Prognose dieser Patienten bestimmen und damit den Sinn dieser Therapie vorhersagen können. Zu den am häufigsten diskutierten und am einfachsten zu bestimmenden Parametern gehört die Anzahl der Metastasen. Ziel dieser Studie war es daher die Wertigkeit dieses Parameters in der Literatur zu reflektieren und unsere eigenen Patientendaten zu evaluieren. Insgesamt konnte von 302 Patienten ein komplettes Follow-up erhoben werden. Die gebildeten Patientengruppen wurden mit Hilfe einer Kaplan Meier Analyse und konsekutivem log rank Test untersucht. Die Literatur wurde bis Dezember 1998 revidiert. Die Anzahl der Metastasen bestätigte sich als ein prognostisches Kriterium. Lagen drei oder mehr Metastasen vor, so war nicht nur die Wahrscheinlichkeit einer R0 Resektion deutlich geringer (17.8% versus 67.2%) sondern auch das Überleben der Patienten nach einer R0 Resektion tendenziell unwahrscheinlicher. Das 5-Jahres Überleben betrug bei > 2 Metastasen 9% bei > 2 Metastasen 36%. Das 10-Jahres Überleben beträgt bislang bei > 2 Metastasen 0% bei > 2 Metastasen 18% (p < 0.07). Die Anzahl der Metastasen spielt in der Prognose der Patienten mit kolorektalen Lebermetastasen eine Rolle. Selbst bei mehr als vier Metastasen ist jedoch gelegentlich eine R0 Resektion möglich. In diesen Fällen kann der Patient auch langfristig von einer Operation profitieren. Das wichtigere Kriterium einer onkologisch sinnvollen Resektabilität ist die Frage ob technisch und funktionell eine R0 Resektion durchführbar ist. Ist das der Fall, so sollte auch einem Patienten mit mehreren Metastasen die einzige kurative Chance einer Resektion nicht vorenthalten bleiben.

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.
