It is well documented that FOXP1 is overexpressed with poor prognosis in diffuse large B-cell lymphoma (DLBCL) [61–64], primary cutaneous large B-cell lymphomas (PCLBCL) [65, 66], follicular lymphoma [67] and gastric mucosa-associated lymphoid tissue lymphoma (MALT) [68] as an oncogene. Here, FOXP1 is linked to diffuse large B-cell lymphoma.
