Autologous Sarcoma Cell Lysate

**Semantic type:** Pharmacologic Substance

**Definition:** A cell lysate derived from sarcoma cells with potential immunostimulatory and antineoplastic activities. Upon intradermal administration, the autologous sarcoma cell lysate exposes the immune system to an undefined amount of sarcoma-type tumor associated antigens (TAA), which may result in the induction of both specific anti-tumoral cytotoxic T lymphocytes (CTL) and antibody-dependent responses against the sarcoma TAA-expressing cells, resulting in sarcoma cell lysis.
