Hepatobiliary scintigraphy and liver function changes in patients with hepatocellular carcinoma treated with Ho-radioembolization : HBS in HCC treated with holmium-166.

Background: To study the feasibility of hepatobiliary scintigraphy (HBS) to improve selection and planning of patients with hepatocellular carcinoma (HCC) treated with holmium-166 (Ho)-microspheres radioembolization.

Results: Thirty-one patients with HCC were included and treated with Ho- radioembolization as part of a prospective phase 2 study. Twenty-seven patients were eligible for analysis, 67% had a cirrhotic liver morphology on imaging, 70% had multifocal disease and 51% had bilobar disease.

Long-term outcomes of more than a decade treating patients with stereotactic body radiation therapy for hepatocellular carcinoma.

Purpose/objectives: To evaluate if stereotactic body radiotherapy (SBRT) for hepatocellular carcinoma (HCC) has a durable effect on tumor control and can be delivered safely.

Materials/methods: Patients included in this retrospective study have been treated at our institution from January 2008 to December 2022. Eligibility criteria were diagnosis of HCC, BCLC stage 0-A-B, non-cirrhotic liver or liver with cirrhosis Child-Pugh class A, and a maximum of three lesions with a cumulative diameter of ≤ 6 cm.

Unlocking the therapeutic potential of the NKG2A-HLA-E immune checkpoint pathway in T cells and NK cells for cancer immunotherapy.

Immune checkpoint blockade, which enhances the reactivity of T cells to eliminate cancer cells, has emerged as a potent strategy in cancer therapy. Besides T cells, natural killer (NK) cells also play an indispensable role in tumor surveillance and destruction. NK Group 2 family of receptor A (NKG2A), an emerging co-inhibitory immune checkpoint expressed on both NK cells and T cells, mediates inhibitory signal via interaction with its ligand human leukocyte antigen-E (HLA-E), thereby attenuating the effector and cytotoxic functions of NK cells and T cells.

Holmium-166 radioembolisation dosimetry in HCC.

Purpose: To evaluate dosimetry, dose-response and dose-toxicity relationships for holmium-166 (Ho) radioembolisation in patients with hepatocellular carcinoma (HCC).

Methods: Thirty-one patients with hepatocellular carcinoma were included in the HEPAR Primary study (NCT03379844, registered on December 20th, 2017) and underwent Ho-microspheres radioembolisation. Linear mixed models assessed the association between tumour absorbed doses and response based on mRECIST both on tumour and patient level.

Hepatocellular adenomas with severe intra-abdominal bleeding, related to an underlying coagulation disorder: a case report.

Background: Hepatocellular adenoma is a rare benign liver tumor. Typically, hepatocellular adenomas are solitary and are found in young women who use estrogen-containing contraceptives. The occurrence of multiple hepatocellular adenoma has been linked to higher body mass index, and as the prevalence of overweight increases, multiple hepatocellular adenomas are seen more often.
