Recently, TSLP has been linked to the pathogenesis of different tumors, like breast cancer (Kuan and Ziegler 2018), acute lymphocytic leukemia (ALL) (Astrakhan et al. 2007), cutaneous T cell lymphomas (Takahashi et al. 2016), and enhanced lung metastasis (Burkard-Mandel et al. 2018). This evidence concerns the gene TSLP and acute lymphoblastic leukemia.
