RESUMEN
In 2023, the NCCN Guidelines for Hepatobiliary Cancers were divided into 2 separate guidelines: Hepatocellular Carcinoma and Biliary Tract Cancers. The NCCN Guidelines for Biliary Tract Cancers provide recommendations for the evaluation and comprehensive care of patients with gallbladder cancer, intrahepatic cholangiocarcinoma, and extrahepatic cholangiocarcinoma. The multidisciplinary panel of experts meets at least on an annual basis to review requests from internal and external entities as well as to evaluate new data on current and emerging therapies. These Guidelines Insights focus on some of the recent updates to the NCCN Guidelines for Biliary Tract Cancers as well as the newly published section on principles of molecular testing.

Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide accounting for over 800,000 new cases in 2018, with the highest incidence in Asia and Africa where hepatitis B is the most common risk factor. In Europe, Japan, and the United States, hepatitis C chronic alcohol abuse and non-alcoholic fatty liver disease are more common risk factors. Five-year survival is low, less than 20% worldwide. HCC is a particularly challenging disease to treat because therapeutic options and prognosis must also consider hepatitis or cirrhosis independent of the malignancy. Locoregional therapies (LRT) including ablation, arterially directed therapy and external beam radiation are the preferred treatments for patients with good performance status, unresectable disease limited to the liver and preserved liver function. In practice, patients with portal vein tumor thrombus and limited extrahepatic disease may also be considered candidates for LRT. There are several guidelines developed by expert panels provide recommendations on treating this challenging disease including the Barcelona Clinic Liver Cancer, European Association for the Study of the Liver, European Society for Medical Oncology, American Association for the Study of the Liver Diseases, and the National Comprehensive Cancer Network. The purpose of this paper is to review the guidelines as they are applied clinically in regions with high incidence of HCC.

Purpose To compare the effect of autologous blood patch injection (ABPI) with that of a hydrogel plug on the rate of pneumothorax at CT-guided percutaneous lung biopsy. Materials and Methods In this prospective randomized controlled trial ( https://ClinicalTrials.gov , NCT02224924), a noninferiority design was used for ABPI, with a 10% noninferiority margin when compared with the hydrogel plug, with the primary outcome of pneumothorax rate within 2 hours of biopsy. A type I error rate of 0.05 and 90% power were specified with a target study population of 552 participants (276 in each arm). From October 2014 to February 2017, all potential study participants referred for CT-guided lung biopsy (n = 2052) were assessed for enrollment. Results The data safety monitoring board recommended the trial be closed to accrual after an interim analysis met prespecified criteria for early stopping based on noninferiority. The final study group consisted of 453 participants who were randomly assigned to the ABPI (n = 226) or hydrogel plug (n = 227) arms. Of these, 407 underwent lung biopsy. Pneumothorax rates within 2 hours of biopsy were 21% (42 of 199) and 29% (60 of 208); chest tube rates were 9% (18 of 199) and 13% (27 of 208); and delayed pneumothorax rates within 2 weeks after biopsy were 1.4% (three of 199) and 1.5% (three of 208) in the ABPI and hydrogel plug arms, respectively. Conclusion Autologous blood patch injection is noninferior to a hydrogel plug regarding the rate of pneumothorax after CT-guided percutaneous lung biopsy. © RSNA, 2018 Online supplemental material is available for this article.

OBJECTIVE: To assess the imaging features of primary hepatic angiosarcoma on multiphasic CT and MR. METHODS: Multi-institutional review identified 35 adults (mean age, 57.1 years; 22M/13F) with pathologically proven hepatic angiosarcoma and pretreatment multiphasic CT (n = 33) and/or MR (n = 7). RESULTS: Multifocal hepatic involvement was seen in all 35 cases, with at least 10 lesions in 74.3% (26/35). Mean size of the dominant mass was 8.9 ± 4.7 cm (range, 2.6-20 cm). Individual nodules were typically circumscribed. Arterial-phase foci of hypervascular enhancement without washout were seen in 89.7% (26/29). Heterogeneously expanding foci of enhancement generally followed blood pool in 88.6% (31/35). Progressive centripetal (n = 16) or diffuse "flash-fill" (n = 4) enhancement pattern resembling cavernous haemangiomas predominated in 20 cases, whereas a "reverse haemangioma" centrifugal pattern predominated in 11 cases. Rapid interval growth was seen in 24 (96.0%) of 25 cases with serial imaging. Vascular invasion was not seen in any case. Underlying cirrhotic morphology was seen in 42.3% (15/35). CONCLUSION: Primary hepatic angiosarcomas typically manifest as aggressive multifocal tumors containing small heterogeneous hypervascular foci that progressively expand and follow blood pool. The appearance can mimic cavernous haemangiomas, but distinction is generally possible. In the setting of cirrhosis, lack of tumour washout and vascular invasion argue against multifocal hepatocellular carcinoma. KEY POINTS: ⢠Hepatic angiosarcoma manifests on CT and MR as rapidly progressive multifocal tumours ⢠Multiphasic imaging demonstrates hypervascular foci that progressively expand and follow blood pool ⢠Enhancement pattern can resemble cavernous haemangiomas or show a "reverse" centrifugal pattern ⢠Lack of tumour washout of hypervascular lesions argues against multifocal hepatocellular carcinoma ⢠Careful assessment of the cross-sectional imaging findings may suggest the diagnosis.

BACKGROUND: Resection has been the standard of care for patients with solitary hepatocellular carcinoma (HCC). Transarterial embolization and percutaneous ablation are alternative therapies often reserved for suboptimal surgical candidates. Here we compare long-term outcomes of patients with solitary HCC treated with resection versus combined embo-ablation. METHODS: We previously reported a retrospective comparison of resection and embo-ablation in 73 patients with solitary HCC<7 cm after a median follow-up of 23 months. This study represents long-term updated follow-up over a median of 134 months. RESULTS: There was no difference in survival among Okuda I patients who underwent resection versus embo-ablation (66 vs 58 months, p=.39). There was no difference between the groups in the rate of distant intrahepatic (p=.35) or metastatic progression (p=.48). Surgical patients experienced more complications (p=.004), longer hospitalizations (p<.001), and were more likely to require hospital readmission within 30 days of discharge (p=.03). CONCLUSION: Over a median follow up of more than 10 years, we found no significant difference in overall survival of Okuda 1 patients with solitary HCC<7 cm who underwent surgical resection versus embo-ablation. Our data suggest that there may be a greater role for primary embo-ablation in the treatment of potentially resectable solitary HCC.
