The present invention refers to a method of treating a carcinoma by administration of one or more of an oligonucleotide comprising the sequence of miR-198 (SEQ ID NO: 1) or a functional part thereof, or an oligonucleotide which reduces expression of Follistatin-related protein 1 (FSTL1), Protein diaphanous homolog 1 (DIAPH1), Laminin subunit gamma-2 (LAMC2) or Urokinase-type plasminogen activator (PLAU). Preferably, the at least one or more oligonucleotides directed against FSTL1, DIAPH1, LAMC2 or PLAU is a shRNA or siRNA. Also provided is a method of determining the presence of carcinoma in a subject, comprising detecting and comparing the presence of miR-198 and/or at least one of FSTL1, DIAPH1, LAMC2 or PLAU, miR-181a, epidermal growth factor (EGF), and epidermal growth factor receptor (EGFR), and comparing the detected levels with that in a control sample.
