The advantages of hepatic artery infusion chemotherapy (HAIC) combined with targeted therapy and immunotherapy for this complex disease are gradually becoming apparent. However, HAIC still has some inevitable disadvantages, such as arterial perfusion therapy requiring a long time, which results in many patients having difficulty completing the procedure. Modified HAIC (mHAIC)-based oxaliplatin and S-1 is a new treatment option for huge HCC or PVTT that can reduce complications and improve patient compliance. We report two cases of huge HCC or PVTT that were successfully treated with mHAIC combined with lenvatinib and camrelizumab. The clinical presentations, treatment strategies, and outcomes of these cases are presented.Case Presentation: Case 1: A 52-year-old female was found to have a huge HCC with a size of 14× 11 cm. She was treated with one cycle of mHAIC combined with transcatheter arterial chemoembolization (TACE), lenvatinib and camrelizumab and 3 cycles of mHAIC in combination with lenvatinib and camrelizumab. The patient’s follow-up maintenance therapy with lenvatinib and camrelizumab has been evaluated for efficacy in achieving complete response (CR). Case 2: A 57-year-old man was diagnosed with advanced HCC in combination with PVTT. He achieved partial remission (PR) after four cycles of mHAIC combined with lenvatinib and camrelizumab. This was followed by treatment with lenvatinib and camrelizumab with an efficacy assessment for CR, and progression-free survival (PFS) was 7 months.Conclusion: For advanced HCC with a large mass or PVTT, mHAIC combined with lenvatinib and camrelizumab is a safe and effective treatment with good patient compliance.Keywords: huge HCC, PVTT, mHAIC, case report
