8. A method for treating a tumor in biliary system, liver cancer, triple negative breast cancer and/or lung cancer, comprising administering to a subject an effective amount of an anti-PD-L1 antibody and anlotinib, wherein the anti-PD-L1 antibody comprises an amino acid sequence as follows: a heavy chain CDR1 region having an amino acid sequence set forth in SEQ ID NO: 1; a heavy chain CDR2 region having an amino acid sequence set forth in SEQ ID NO: 2; a heavy chain CDR3 region having an amino acid sequence set forth in SEQ ID NO: 3; a light chain CDR1 region having an amino acid sequence set forth in SEQ ID NO: 7; a light chain CDR2 region having an amino acid sequence set forth in SEQ ID NO: 8; and a light chain CDR3 region having an amino acid sequence set forth in SEQ ID NO: 9.
9. The method according to claim 8 , wherein the anti-PD-L1 antibody and anlotinib are packaged separately.
10. The method according to claim 9 , wherein the anti-PD-L1 antibody and anlotinib are each in the form of a pharmaceutical composition that can be administered simultaneously, sequentially or at intervals.
11. The method according to claim 9 , wherein the anti-PD-L1 antibody is administered once every week, every 2 weeks, every 3 weeks, or every 4 weeks at a dose of 600-2400 mg.
12. The method according to claim 9 , wherein anlotinib is administered at a dose of 6 mg, 8 mg, 10 mg, or 12 mg once daily with a regimen of 2-week treatment and 1-week interruption.
13. A kit for use in treating a tumor in biliary system, liver cancer, triple negative breast cancer and/or lung cancer, comprising a pharmaceutical composition of an anti-PD-L1 antibody, a pharmaceutical composition of anlotinib, and an instruction for combined use of the anti-PD-L1 antibody and anlotinib in treating a tumor in biliary system, liver cancer, triple negative breast cancer and/or lung cancer, wherein the anti-PD-L1 antibody comprises an amino acid sequence as follows: a heavy chain CDR1 region having an amino acid sequence set forth in SEQ ID NO: 1; a heavy chain CDR2 region having an amino acid sequence set forth in SEQ ID NO: 2; a heavy chain CDR3 region having an amino acid sequence set forth in SEQ ID NO: 3; a light chain CDR1 region having an amino acid sequence set forth in SEQ ID NO: 7; a light chain CDR2 region having an amino acid sequence set forth in SEQ ID NO: 8; and a light chain CDR3 region having an amino acid sequence set forth in SEQ ID NO: 9.
