Percutaneous interstitial chemotherapy of a small hepatocellular carcinoma under ultrasound guidance

A small (less than 3 cm) inoperable hepatocellular carcinoma was treated with percutaneous interstitial chemotherapy (PIC). 5-Fluorouracil was injected by a fine needle under ultrasound guidance. After 3 months a fine needle biopsy (FNB) yielded fibronecrotic material. After 18 months another FNB yielded steatosis and dysplastic cells and the lesion showed no increase in size. PIC could be an interesting alternative treatment for small tumors unresponsive to conventional therapies.
