Background: The optimal surveillance strategy after resection of colorectal liver metastases (CLM) is unknown. We evaluated changes in recurrence risk after CLM resection and developed a surveillance algorithm. Methods: Patients undergoing CLM resection during 1998 to 2015 were identified from a prospectively compiled database and analyzed if they had the potential for follow-up longer than the longest observed time to recurrence in this cohort. Changes in recurrence risk and risk factors for recurrence were evaluated. All statistical tests were 2-sided. Results: Among 2,105 patients who were initially identified and underwent CLM resection, the latest recurrence was observed at 87 months; 1,221 consecutive patients from 1998 through 2011 with the potential for at least 87 months of follow-up were included. The risk of recurrence was highest at 0 to 2 years after CLM resection, lower at 2 to 4 years after CLM resection, and steadily lower after 4 years after CLM resection. Factors associated with increased recurrence risk at the time of surgery were primary lymph node metastasis (hazard ratio [HR], 1.54; 95% CI, 1.21–1.97; P<.001), multiple CLM (HR, 1.31; 95% CI, 1.06–1.63; P=.015), largest liver metastasis diameter >5 cm (HR, 1.64; 95% CI, 1.23–2.19; P<.001), and RAS mutation (HR, 1.29; 95% CI, 1.04–1.59; P=.020). In patients without recurrence at 2 years, the only factor still associated with increased recurrence risk was RAS mutation. In those patients, the recurrence rate at 4 years was 59.3% in patients with RAS mutation versus 27.8% in patients with RAS wild-type (P=.019). Conclusions: For patients who have undergone CLM resection, we propose surveillance every 3 to 4 months during years 0 to 2, every 3 to 4 months (if mutant RAS) versus every 4 to 6 months (if RAS wild-type) during years 2 to 4, and every 6 to 12 months if recurrence-free at 4 years.

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.
