The present invention relates to peptides, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated cytotoxic T cell (CTL) peptide epitopes, alone or in combination with other tumor-associated peptides that serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses. The present invention relates to more than 70 novel peptide sequences and their variants derived from HLA class I and HLA class II molecules of human tumor cells that can be used in vaccine compositions for eliciting anti-tumor immune responses.<；p>；La invenció；n se refiere a pé；ptidos, á；cidos nucleicos y cé；lulas para la utilizació；n en mé；todos inmunoterapé；uticos. En concreto, el documento en estudio se refiere un mé；todo y una inmunoterapia contra el cá；ncer. Particularmente se refiere, a epí；topos peptí；dicos de linfocitos T citotó；xicos (CTL) asociados a tumor, solos o en combinació；n con otros pé；ptidos asociados a tumor que sirven como principios activos farmacé；uticos de composiciones vacunas que estimulan respuestas inmunitarias antitumorales.<；/p>；
