The present invention describes clinically and medically important methods of monitoring the outcome of a cancer patient who is suffering from disease or who is undergoing treatment or therapy for his or her disease. More specifically, the invention provides a method of monitoring the progression of disease or cancer treatment effectiveness in a cancer patient by measuring the level of the extracellular domain (ECD) of the epidermal growth factor receptor (EGFR) in a sample taken from the cancer patient, preferably, before treatment, at the start of treatment, and at various time intervals during treatment, wherein a decrease in the level of the ECD of the EGFR in the cancer patient compared with the level of the ECD of the EGFR in normal control individuals serves as an indicator of cancer advancement or progression and / or a lack of treatment effectiveness for the patient.
