To the Editor ,rnTumor invasion of the inferior vena cava (IVC) through direct erosion is a rare and poor prognostic feature of aggressive hepatic or perihepatic malignancies [1 , 2] . Literature shows poor response to chemotherapy, such that resection often is the only option for improved survival [3] . Multidisciplinary collaborations can expand technical options; incorporation of transplant techniques has led to successful R0 resection involving difficult vascular reconstruction and extended resection [4 , 5] . This study describes and analyzes the ten-year collaborative experience of hepatobiliary (HPB) surgeons in management of malignancies involving the perihepatic IVC.
