Incidence biology diagnosis staging and risk assessment treatment plans response evaluation and follow-up. The ESMO Clinical Practice Guidelines CPG are intended to provide the user with a set of recommendations for the best standards of cancer. The reported prevalence of unknown primary carcinoma UPC varies with the practice setting and the definition used from 05 to 9 of all patients who are diagnosed with cancer 12.
