摘要: Cancer of unknown primary site is a common clinico- pathologic syndrome representing very heterogeneous group patients with metastatic cancers and clinically undetectable tumor sites. The standard treatment for these the last 15 years has been empiric "broad-spectrum" chemo- therapy. In recent years, improved immunocytochemistry emergence gene expression profiling have provided diagnostic tools necessary to accurately define tissue origin in majority patients. Recent data confirmed ability molecular assays complement stan- dard diagnosis, large prospective study documented survival improvement treated site-specific therapy directed by assay diagnoses their tissues compared chemotherapy. clinicopathologic evaluation now more standardized. era chemotherapy administered all coming an end, customized therapies are favored. management evolved confidently origin. Further delin- eation aberrations advanced solid tumors, regardless site, signals precise perhaps effective each patient.
