Few diagnoses in medicine engender as much pessimism as thediagnosis of metastatic cancer of an unknown primary site. Patientswith this syndrome often have widespread metastatic disease,with involvement of multiple visceral sites such as the liver,lungs, and bones, and are often debilitated at the time of diagnosis.Early reports of chemotherapy in these patients documented lowrates of response and no effect on the dismal median survivalof three to four months, thereby strengthening arguments fora nihilistic approach1,2,3,4.
