OBJECTIVE: To investigate the expression level of T lymphocyte subsets in elderly patients with newly diagnosed multiple myeloma (NDMM), and to evaluated the prognostic value of T lymphocytic abnormalities in elderly NDMM patients.
METHODS: Pretreated peripheral blood of 39 newly diagnosed elder patients with MM was tested by multi-parameter flow cytometry (MFC) to quantitatively detect T lymphocyte subsets, including CD4+T cell, CD8+T cell, and CD4/CD8 ratio. The prognostic values T-lymphocyte subset were evaluated in newly diagnosed elderly patients with MM.
RESULTS: The median follow-up time was 21.5 (range, 3.0-66.0) months. Absolute counts of CD4+T cell and CD4/CD8 ratio positively correlated with prognosis. In the multivariate COX analysis, lower CD4/CD8 ratio and CD4+T cell counts were identified to be independent adverse prognostic factors for OS.
CONCLUSION: Lower CD4/CD8 ratio and CD4+T cell counts at initial diagnosis are independent unfavorable prognostic factors for elderly patients with MM, and T lymphocyte subsets are crucial indicators for MM patients' prognosis.
