Background

Hepatocellular carcinoma (HCC) is the second leading cause of cancer‐related death in China. The rapid progress in systemic therapies has led to the approval of many therapeutic methods that have quickly changed clinical guidelines and practices. Because of the high heterogeneity of HCC, there are still some gaps between the guidelines and real‐world clinical practice. The present study surveyed experts in China to investigate the current treatment concepts and clinical practice regarding HCC.

Methods

A questionnaire survey on the treatment concepts and clinical practice of HCC was administered to 310 experts with senior professional titles in 2020 and 312 experts in 2021. The results were analyzed and compared.

Results

For treating patients with resectable HCC, 28% of hepatobiliary surgeons indicated neoadjuvant therapy, and 7% chose systemic therapy ± locoregional therapy as 1 L therapy in 2021 compared with 20% and 1% in 2020. More experts chose adjuvant treatment within 1 month in 2021 compared with 2020, and 6 months and 12 months were the leading choices for the duration of adjuvant treatment. In 2021, 79% of surgeons and 19% of interventionalists were willing to conduct downstaging/conversion therapy for patients with potentially resectable HCC, and 78% chose tyrosine kinase inhibitors (TKI) + immunotherapy (IO) + locoregional therapy for cases in which R0 resection could not be achieved. For completely unresectable HCC, more experts preferred TKI + IO‐based therapy as 1 L therapy in 2021 compared with 2020 (78% vs. 55%). The proportion of experts who indicated TKI + IO‐based therapy as 2 L therapy increased from 32% in 2020 to 40% in 2021.

Conclusion

The survey results indicated that in 2021, compared with 2020, more experts opted to administer IO + TKI for the treatment of liver cancer, and more experts and patients were willing to participate in clinical research.

Neuroendocrine tumours (NETs) are rare cancers with positive somatostatin receptor 2 (SSTR2) expression, and treatment strategies for NETs are not satisfactory. Nanomaterial-mediated therapy targeting SSTR2 in NETs is very promising. This study firstly combined mesoporous silica-coated gold nanorods (AuNRs@mSiO2) and targeting-SSTR2 dodecane tetraacetic acid-tyrosine3-octreotate (DOTA-TATE) into AuNRs@mSiO2@DOTA-TATE to investigate NETs inhibition under near-infrared light. AuNRs@mSiO2@DOTA-TATE showed good photothermal conversion efficiency. In vitro, under light irradiation, the cell viability significantly decreased with increasing AuNR@mSiO2@DOTA-TATE concentration; in two successfully established neuroendocrine tumour organoids with SSTR2 expression, AuNRs@mSiO2@DOTA-TATE with light inhibited tumours significantly better than AuNRs@mSiO2 with light. In vivo, the SSTR2-targeting ability and biodistribution of AuNRs@mSiO2@DOTA-TATE were confirmed with AuNRs@mSiO2@64Cu-DOTA-TATE under micro-positron emission tomography/computed tomography (micro-PET/CT); in the AuNRs@mSiO2@DOTA-TATE with laser group, the tumour surface temperature increased rapidly, with tumour volumes similar to those in the octreotide group and significantly lower than those in other groups. There was no significant difference in mice body weight between the AuNRs@mSiO2@DOTA-TATE with laser group and other groups. No significant inflammatory lesions or cell necrosis was found in the main organs. In summary, we presented a feasible strategy to construct AuNRs@mSiO2@DOTA-TATE with good photothermal conversion efficiency, targeting-SSTR2 ability, significant antitumour effects, and good biocompatibility, warranting further explorations of AuNRs@mSiO2@DOTA-TATE for NETs therapy applications.
