Abstract: The present invention relates to a composition capable of preventing or treating cancer, particularly pancreatic cancer. The composition can effectively inhibit the growth or proliferation of cancer cells, and furthermore, effectively prevent the resistance of cancer cells to anticancer agents, or the metastasis or recurrence of cancer, by using an inhibitor of the activity of at least one of interleukin-10 receptor subunit beta (IL-10RB, IL-10R2) and interleukin-22 (IL-22); or an inhibitor of expression of a gene encoding at least one of the interleukin-10 receptor subunit beta and the interleukin-22.
