Any measurement which expresses a quantity related to the beginning, early stages or development of a T-cell lymphoma, or to the official determination of T-cell lymphoma as the cause of the observed symptom(s). T-cell lymphoma refers to a heterogeneous group of usually malignant lymphoid neoplasms that occur as circumscribed solid tumors and that are composed of T lymphocytes. T lymphocytes are white blood cells that complete maturation in the thymus and that have various roles in the immune system, including the identification of specific foreign antigens in the body, the mediation of cellular immune responses, and the activation and deactivation of other immune cells.
