Surgical treatment of hepatocellular carcinoma in the era of COVID-19 pandemic: A comprehensive review of current recommendations.

ABSTRACT

The new coronavirus disease 2019 (COVID-19) pandemic has resulted in a global health emergency that has also caused profound changes in the treatment of cancer. The management of hepatocellular carcinoma (HCC) across the world has been modified according to the scarcity of care resources that have been diverted mostly to face the surge of hospitalized COVID-19 patients. Oncological and hepatobiliary societies have drafted recommendations regarding the adaptation of guidelines for the management of HCC to the current healthcare situation. This review focuses on specific recommendations for the surgical treatment of HCC (i.e., hepatic resection and liver transplantation), which still represents the best chance of cure for patients with very early and early HCC. While surgery should be pursued for very selected patients in institutions where standards of care are maintained, alternative or bridging methods, mostly thermoablation and transarterial therapies, can be used until surgery can be performed. The prognosis of patients with HCC largely depends on both the characteristics of the tumour and the stage of underlying liver disease. Risk stratification plays a pivotal role in determining the most appropriate treatment for each case and needs to balance the chance of cure and the risk of COVID-19 infection during hospitalization. Current recommendations have been critically reviewed to provide a reference for best practices in the clinical setting, with adaptation based on pandemic trends and categorization according to COVID-19 prevalence.
