IL-32 was further reported to be associated with the occurrence and development of various malignant tumors such as gastric cancer, lung cancer, and cutaneous T-cell lymphoma (Sorrentino and Di Carlo, 2009; Kang et al., 2012; Yousif et al., 2013; Tsai et al., 2014; Gruber et al., 2020), suggesting it has a critical role in tumor development. Here, IL32 is linked to primary cutaneous T-cell non-Hodgkin lymphoma.
