Significance: Pyroptosis is a discovered programmed cell death that is mainly executed by the gasdermin protein family. Cell swelling and membrane perforation are observed when pyroptosis occurs, and is accompanied by the liberation of cell contents. Recent Advances: As the study of pyroptosis continues to progress, there is increasing evidence that pyroptosis influences the development of tumors. In addition, the relationship between pyroptosis and tumor is diverse for different tissues and cells. Critical Issues: In this review, we first introduce the research history and molecular mechanisms of pyroptosis. Then we specifically discuss the link between pyroptosis and metabolic and oxidation in tumorigenesis. In the subsequent sections, we focus on the induction of pyroptosis in cancer and its potential role as a promising target for cancer therapy, and discuss the implications of pyroptosis in tumor treatment. In addition, we further summarize the therapeutic value of pyroptosis in tumor treatment. Future Directions: A detailed understanding of the role played by pyroptosis in tumors will help us to further explore tumor formation and progression and provide ideas for the development of new pyroptosis-based therapeutic approaches for patients.
