A process for detecting malignant transformation of cells involves detecting the overexpression of the products of the beta3, beta5, beta8 and beta9 genes, which encode the hCGbeta subunit, relative to their expression in nonmalignant cells. A kit for diagnosing an hCG- or an hCG fragment-secreting cancer includes an assembly of polypeptides covering at least a part of the primary sequence of hCG. The use of a polypeptide corresponding to at least one portion of the primary sequence of hCG for producing a composition useful in hCG- or hCG fragment-secreting cancer immunotherapy is also disclosed.
