The waiting interval after chemoradiotherapy (CRT) is an interesting therapeutic window to treat patients with synchronous liver metastases (SLM) from rectal cancer.A retrospective analysis was performed of 18 consecutive patients (M/F 10/8, age (range) 60 (51-75) years) from five institutions who underwent liver resection of SLM during the waiting interval after CRT for rectal adenocarcinoma.All patients underwent interval liver surgery for a median (range) of 4 (2-14) liver metastases. Metastases involved a median (range) of 4 (1-7) liver segments. Median (range) time between end of CRT and liver surgery was 22 (6-45) days. Laparoscopic liver surgery was performed in 12 (67%) patients. No severe complications (Clavien-Dindo ≥ 3b) occurred after liver surgery. Median (range) length of hospital stay after liver surgery was 5 (1-10) days. All patients subsequently underwent rectal resection at a median (range) of 10 (8-13) weeks after end of CRT. Median (IQR) time-to-progression after liver surgery was 4.2 (2.8-9.2) months.The waiting interval after neoadjuvant CRT is a valuable option to treat SLM from rectal cancer. More data are necessary to confirm its oncological efficacy.
