Brief summary
Dendritic cells (DCs)are the most potent antigen-presenting cells of the immune system, as such they are able to direct the immune system specifically against cancer cells. Currently DCs are used in clinical vaccination studies and immunological and clinical responses have been observed. For inducing anti-tumor immunity, the DCs have to be loaded with tumor antigen (i.e. molecular structures that are presented by the tumor, that are recognized by the immune system). Currently most studies use tumor peptides (small protein fragments) for this purpose. This approach has several disadvantages: only patients with a certain HLA-type can be treated and the immune response that is induced by the vaccine is limited to the used peptides. These disadvantages do not exist when the DCs present antigen which is endogenously processed, for example after RNA transfection. For this reason we investigate the immunogenicity of DCs that are pulsed with peptides or transfected with mRNA encoding melanoma associated antigens in stage III and IV melanoma patients.

Exclusion criteria
For both stage III and IV * No autoimmune disorders, no concomitant use of immunosuppressive drugs, * no serious concomitant disease, no serious active infections, no other malignancy in the past 5 years with the exception of curatively treated carcinoma in-situ of the cervix/squamous cell carcinoma of the skin, * No known allergy to shell fish (contains KLH) are excluded. * No pregnancy or lactation, For stage III only: * No signs or symptoms of distant metastases as defined by normal history, physical examination, chest X-ray and serum LDH. * No concomitant or previous systemic treatment for melanoma For stage IV only: * No clinical signs of CNS metastases, in patients with a clinical suspicion of CNS metastases, a CT scan of the brain should be performed to exclude this. * No prior chemotherapy, immunotherapy, or radiotherapy within three months before planned vaccination is allowed.
