What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Feasibility of a method allowing identification of tumor mutated epitopes in patients with breast cancer or cutaneous melanoma and quantification of CD8+ T cells specific for the tumor neo-antigens identified in the lymph nodes.	Feasibility study for a method allowing identification of tumor mutated epitopes : Identification of MHC cl I and II restricted tumor neo-epitopes by two different methods i.e. by an elution-HPLC method performed on cell lines derived from tumor cells obtained from invaded lymph node, or using predictive algorithms on tumor sequencing data.	up to 24 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Quantification of CD4+ T lymphocytes specific for identified tumor neo-antigens in the lymph nodes.		up to 24 months
Quantification of CD4+ and CD8+ T lymphocytes specific for identified neo-antigens in the blood and tumor.		up to 24 months
Comparison of the frequency and relative amplitude of the T cell response specific for the tumor neo-epitopes with other immune responses and responses against known tumor antigens.	Comparison of the frequency and relative amplitude of the T cell response specific for the tumor neo-epitopes with other immune responses such as anti-viral memory responses (influenza A, ...), chronic viral responses (cytomegalovirus [CMV] Epstein-Barr virus [EBV], ...) and responses against known tumor antigens (such as NY-ESO-1, MAGE-A3, p53, gp100 ....).	up to 24 months
