Safety of implanting sustained-release 5-fluorouracil into hepatic cross-section and omentum majus after primary liver cancer resection

This study was designed to evaluate the short-term safety of implanting sustained-release 5-fluorouracil (5-FU) into hepatic cross-section and omentum majus after primary liver cancer resection and its impact on related indexes of liver. Forty patients were selected and divided into an implantation group (n = 20) and a control group (n = 20). On the first day after admission, first week after surgery, and first month after surgery, fasting venous blood was extracted from patients for measuring hematological indexes. The reduction rate of alpha fetoprotein (AFP) on the first week and first month after surgery was calculated, and moreover, drainage volume of the abdominal cavity drainage tube, length of stay after surgery, and wound healing condition were recorded. We found that levels of alanine aminotransferase, aspartate amino transferase, blood urea nitrogen, creatinine, total bilirubin, albumin, and white blood cells measured on the first week and first month after surgery, length of stay, and wound healing of patients in the two groups had no significant difference (P >0.05). Drainage volume and reduction rate of AFP of two groups were significantly different on the first week and first month after surgery (P <0.05). Implanting sustained-release 5-FU into hepatic cross-section and omentum majus after primary liver cancer resection is proved to be safe as it has little impact on related indexes.
