Natural cell-mediated immunity against autologous tumor cells, autologous endometrial epithelium, and allogeneic epidermoid carcinoma cell line HeLa was tested in 8 patients with endometrial carcinoma and one patient with endometrial stromal sarcoma. The average cytotoxicity of unstimulated peripheral blood lymphocytes against autologous tumor and HeLa cells was weak but significant. Pretreatment of effector cells for 3-5 days with 300 U/ml recombinant interleukin-2 (rIL-2) resulted in increased cytotoxicity against malignant target cells in 7 out of 9 cases. The 2 patients' effector cells which were refractory to rIL-2 could be stimulated to appreciable lytic activity against the malignant target cells with a recently described cytokine which induces morphological differentiation of natural killer cells. Benign endometrial cells were weakly sensitive to rIL-2-activated lysis in 2 cases. The precursors of the rIL-2-activated killer cells were mostly CD16-positive and CD3-negative, and co-sedimented with endogenous natural killer cells in discontinuous density gradient centrifugations. These results indicate the rIL-2-activated killer cells have a capacity to distinguish between normal and malignant endometrial cells, and that the precursors of the lytic cells in this system belong to the same subpopulation of lymphocytes as endogenous natural killer cells. In addition, rIL-2 alone may not in all cases be sufficient for optimal generation of cytotoxicity against malignant cells.

Curcumin is a botanical with anti-tumor and immunomodulatory properties. We hypothesized that curcumin supplementation might influence inflammatory biomarker levels in endometrial carcinoma (EC). In this open-label, non-randomized phase 2 study (NCT02017353), seven EC patients consumed 2 g/day Curcumin Phytosome (CP) orally for 2 weeks. Blood was taken at baseline, days 1, 7, 14, and 21. The following analytes were measured: curcuminoids and metabolites, 56 inflammatory biomarkers, COX-2, frequencies of myeloid-derived suppressor cells, dendritic cells and NK cells, expression of MHC molecules on leukocytes and monocytes and activation/memory status of T cells. Patients completed quality of life (QoL) questionnaires at baseline and end of treatment. Curcumin metabolites were detectable in plasma upon CP intake. CP downregulated MHC expression levels on leukocytes (P = 0.0313), the frequency of monocytes (P = 0.0114) and ICOS expression by CD8+ T cells (P = 0.0002). However, CP upregulated CD69 levels on CD16- NK cells (P = 0.0313). No differences were observed regarding inflammatory biomarkers, frequencies of other immune cell types, T cell activation and COX-2 expression. A non-significant trend to improved QoL was observed. Overall, CP-induced immunomodulatory effects in EC were modest without significant QoL changes. Given the small population and the observed variability in inter-patient biomarker levels, more research is necessary to explore whether benefits of CP can be obtained in EC by different supplementation regimens.
