摘要Thrombocytopenia and liver injury are serious clinical problems in patients with cancer.The etiology of thrombocytopenia in patients with cancer and liver injury(TCLI)is complicated.Managing cancer therapy-induced thrombocytopenia has gradually become standardized,and managing liver injury-associated thrombocytopenia has become more effective with the approval and marketing of relevant drugs.However,the optimal strategy for managing thrombocytopenia in patients with cancer and liver injury remains unclear,and the superposition of thrombocytopenia and liver injury further increases the difficulty of cancer treatment.Therefore,the Committee of Cancer Support Therapy of the Chinese Anti-Cancer Association has organized experts to analyze and discuss relevant literature to form a Chinese expert consensus on managing thrombocytopenia in patients with cancer and liver injury(2022 Edition)to guide clinical practice.
