Needle track seeding after radiofrequency ablation for hepatocellular carcinoma: prevalence, impact, and management challenge

چکیده

Neoplastic seeding may arise after radiofrequency ablation (RFA) for hepatocellular carcinoma (HCC). A low risk of seeding after RFA (0-1.1%) has been reported, which may rise up to 2.5% if ablation followed diagnostic biopsy. Needle track seeding presents with one or multiple rounded nodules along the needle track located within the peritoneum, along the abdominal muscles, which were penetrated by the needle, pleural surface, or in the subcutaneous and cutaneous tissues. The most widely used method for the assessment of seeding nodules is ultrasound (US), which usually displays hypoechoic nodules with intralesional vascularization. Fine needle aspiration biopsy of the nodule suspicious for malignant implant is mandatory to confirm the diagnosis and plan therapy. Wide surgical excision is the treatment of choice for neoplastic seeding. Thanks to early diagnosis and prompt treatment, development of needle track seeding is not likely to affect the long-term survival of patients.

Cutaneous metastasis from hepatocellular carcinoma after a percutaneous interventional procedure.

Cutaneous metastases from hepatocellular carcinoma are very uncommon, and, according to one series, account for just 0.8% of all cutaneous metastases. Iatrogenic factors appear to be the most common cause and include needle tract seeding during percutaneous interventional procedures and surface seeding of tumor cells during surgery. We present the case of a 35-year-old man with a history of chr...

Treatment and clinical outcome of needle-track seeding from hepatocellular carcinoma

BACKGROUND/AIMS Needle-track seeding is a rare but important complication of diagnostic and therapeutic ultrasound (US)-guided procedures in hepatocellular carcinoma (HCC). We examined the frequency of needle-track seeding after US-guided percutaneous ethanol injection (PEI), fine-needle aspiration biopsy (FNAB), and percutaneous transhepatic biliary drainage (PTBD) in order to determine the ap...
