[Does cancer therapy program its failure, too? (author's transl)].

Is seems indispensable, in consideration of the present investigation results, to revise our actual therapeutic conception for cancer therapy! While palliative cancer therapy was greatly successful, it was not possible to obtain any decisive improvement of cancer recovery rates (in relation to similar stages or tumor volumes), in spite of all the therapeutic endeavour through the last twenty or twenty-five years. From almost 3000 analyses of metastatic growth and from numerous other experimental or clinical observations results as an explication that surgical treatment itself, on certain conditions, may release a relatively great number of metastases. Thus, the failure of our therapeutical endeavor is programmed, too, by the treatment! Consequences for diagnostics, precautions and therapy are discussed.
