The present invention relates to immunotherapeutic peptides and their use in immunotherapy, in particular the immunotherapy of cancer. The present invention discloses tumour-associated T-helper cell peptide epitopes, alone or in combination with other tumour-associated peptides that serve as active pharmaceutical ingredients of vaccine compositions which stimulate anti-tumour immune responses. In particular, the composition of the peptides of the present invention can be used in vaccine compositions for eliciting anti-tumour immune responses against colorectal cancer.
