What the trial is, and whether it could suit you
HCC is a huge healthcare burden in Hong Kong and is one of the top 5 cancers in terms of incidence and mortality in Hong Kong. Patients with advanced HCC are treated with immunotherapy-based as first-line treatment as a standard of care. At the moment, there is limited evidence to guide subsequent treatments after patients progressed on immunotherapy. Oligoprogression is a term used to describe patients who had limited progression (usually less than 3 sites) on systemic therapy, with the rest of the lesions controlled. Previous studies in non-HCCs have shown that addition of locoregional treatment (e.g. radiotherapy) may prolong the use of systemic therapy, resulting in improved survival, but this has been relatively unexplored for HCC. In this prospective, single-arm study, we aim to evaluate the treatment outcome, efficacy and safety of the addition of radiotherapy to oligoprogressive

12. Adequate hepatic function (albumin ≥ 28g/L; Bilirubin ≤ 2.5xULN; ALT \< 5 times upper limit normal)
13. Adequate renal function (serum creatinine ≤ 1.5 times the upper limit of normal range; Na ≥ 130mmol/L; K ≥ 3.0mmol/L)
14. Able to read, understand and provide written consent
Exclusion Criteria:
1. History of another malignancy except appropriately-treated BCC of skin or CIN of cervix during the last 5 years
