Needle track seeding following biopsy of liver lesions in the diagnosis of hepatocellular cancer: a systematic review and meta-analysis
M A Silva1, B Hegab1, C Hyde2, B Guo2, J A C Buckels1, D F Mirza1
Background: Needle biopsy of a suspicious liver lesion could guide management in the setting of equivocal imaging and serology, although it is not recommended generally because there is the possibility of tumour dissemination outside the liver. The incidence of needle track seeding following biopsy of a suspicious liver lesion is ill-defined, however.
Methods: A systematic review and meta-analysis of observational studies published before March 2007 was performed. Studies that reported on needle tract seeding following biopsy of suspicious liver lesions were identified. Lesions suspected of being hepatocelleular cancer (HCC) were considered. Data on the type of needle biopsy, diagnosis, incidence of needle track seeding duration to seeding, follow-up and impact on outcome were tabulated.
Results: Eight studies identified by systematic review on biopsy of HCC were included in a meta-analysis. The pooled estimate of a patient with seeding per 100 patients with HCC was 0.027 (95% confidence interval (CI) 0.018 to 0.040). There was no difference whether a fixed or random effects model was used. Q was 4.802 with 7 degrees of freedom, p = 0.684; thus the observed heterogeneity was compatible with variation by chance alone. The pooled estimate of a patient with seeding per 100 patients per year was 0.009 (95% CI 0.006 to 0.013), p = 0.686.
Conclusions: In this systematic review we have shown that the incidence of needle tract tumour seeding following biopsy of a HCC is 2.7% overall, or 0.9% per year.

Seeding following percutaneous diagnostic and therapeutic approaches for hepatocellular carcinoma. What is the risk and the outcome? Seeding risk for percutaneous approach of HCC.Stigliano R, Marelli L, Yu D, Davies N, Patch D, Burroughs AK.
BACKGROUND: Tumour biopsy is usually considered mandatory for patient management by oncologists. Currently percutaneous ablation is used therapeutically for cirrhotic patients with small hepatocellular carcinoma (HCC), not suitable for resection or waiting for liver transplantation. However malignant seeding is a recognized complication of both diagnostic and therapeutic procedures in patients with HCC. Although percutaneous therapy whether with or without biopsy of a suspected HCC nodule may minimize the risk of seeding, this has not been confirmed.
AIM: To evaluate the risk of seeding, defined as new neoplastic disease occurring outside the liver capsule, either in the subcutaneous tissue or peritoneal cavity following needle biopsy and/or local ablation therapy (LAT).
METHODS: A literature search resulted in 179 events in 99 articles between January 1983 and February 2007: 66 seedings followed liver biopsy, 26 percutaneous ethanol injection (PEI), 1 microwave, 22 radiofrequency ablation (RFA), and 64 after combined biopsy and percutaneous treatment (5 microwave; 33 PEI; 26 RFA).
RESULTS: In 41 papers specifying the total number of patients biopsied and/or treated, the median risk of seeding was 2.29% (range 0-11%) for biopsy group; 1.4% (1.15-1.85%) for PEI when used with biopsy and 0.61% (0-5.56%) for RFA without biopsy, 0.95% (0-12.5%) for RFA with biopsy and 0.72% (0-10%) for liver nodules (including non-HCC nodules) biopsied and ablated.
CONCLUSION: Risk of seeding with HCC is substantial and appears greater with using diagnostic biopsy alone compared to therapeutic percutaneous procedures. This risk is particularly relevant for patients being considered for liver transplantation.
因此,总体上,RFA治疗肝癌被认为是微创、安全的。 |
