Spread to the peritoneum not uncommonly occurs in cancers of the gastrointestinal tract, gynaecological cancers. I am aware that, in Singapore, peritonectomy or cytoreductive surgery to remove all visible tumour on the peritoneum followed by the instillation of hyperthermic intraperitoneal chemotherapy or HIPEC into the abdomen to eliminate microscopic disease is performed and, to date, the Peritoneal and Pelvic Malignancy Service at the National Cancer Centre Singapore has performed >100 Peritonectomies and HIPEC and has conducted research projects in this field; I just wonder who are actively doing these work in Hong Kong, thank you!
