title: [Current classification of primary malignant bone tumors].
abstract: The classification of primary malignant bone tumors has to include: 1. Histologic diagnosis, iusing immunohistochemistry especially in small-round- and spindle-cell tumors. 2. Grading of malignancy, iusing proliferation factors. 3. Definition of compartmentalisation. 4. Staging. Only when all these factors are defined it is possible to plan the best therapy, to compare the results of different centers and to overwork it scientifically. Investigation of chromosomes, oncogenes, chemotherapy resistance a.o. are to be added for classification in next future.
