Eight patients (42%) had synchronous metastasis whereas 11 (58%) had metachronous metastasis.

Nine patients (47%) achieved R0 resection, whereas four (21%) and six (32%) patients had R1 and R2 resection, respectively. With a median follow-up period of 26.7 months, the estimated median overall survival (OS) was 18.2 months (95% confidence interval, 13.6\u201322.9 months).
