Flow cytometry assessment of residual melanoma cells in tumor-infiltrating lymphocyte cultures.

Adoptive transfer of tumor-infiltrating lymphocytes (TIL) is in development for the treatment of metastatic melanoma. In phase II clinical trials, patients with metastatic melanoma that received TIL after preconditioning had a 50-70% clinical response rate. The current approach to generate TIL is to culture melanoma enzyme digests in the presence of IL-2 for a 10- to 20-day period followed by 2 weeks of rapid expansion (REP).

Systemic therapy for cutaneous melanoma.

This article provides a review of the current medical management of patients with high-risk and metastatic cutaneous melanoma, including a review of the use of adjuvant interferon therapy and a discussion of adjuvant treatments under evaluation. The use of standard chemotherapeutic agents for metastatic disease is discussed, with an emphasis on developmental therapeutics using targeted agents. This discussion includes a review of the immune therapy for metastatic melanoma, including newer immunomodulatory agents and cellular therapeutics that are expected to significantly impact the care of these patients.

Immune Modulation in Cancer Patients After Adoptive Transfer of Anti-CD3/Anti-CD28-Costimulated T Cells-Phase I Clinical Trial.

Anti-CD3/anti-CD28 monoclonal antibody-coactivated T cells (COACTs) proliferate, secrete tumoricidal cytokines, and mediate non-major histocompatibility complex (MHC)-restricted cytotoxicity. This phase I study was done to determine the safety, maximum tolerated dose, technical limits of expansion, and modulation of immune functions in cancer patients given COACTs. Coactivated T cells were produced by stimulating peripheral blood mononuclear cells (PBMCs) with OKT3 anti-CD3 and 9.
