IL10 and peripheral T-cell lymphoma, not otherwise specified: 120). Similarly, high IL-10 levels was found to be a prognostic factor in peripheral T cell lymphoma, which can lead to worsening of overall survival, low complete response rate, and higher early relapse rate (Ref. 122). Moreover, elevated IL-10 at diagnosis was found to be an independent prognostic marker in adult hemophagocytic lymphohistiocytosis patients in order to find the right treatment strategy (Ref. 123).
