Cervical Nodal Metastasis from an Unknown Primary Carcinoma
The diagnostic and therapeutic problems of cervical lymph node metastasis from an occult primary carcinoma are a dilemma for the oncologist. In general, patients who present with metastases and no obvious primary site of origin, have a median survival of three to four months (Holmes and Fouts 1970; Richardson and Parker 1975; Smith et al. 1977). This poor prognosis is not altered by treatment unless a primary site can be identified, or the region that is the most probable primary site can be defined (Nystrom et al. 1977). Autopsy studies of patients who have presented with metastasis from occult primary malignant tumors reveal the site of origin in only 15% of cases.
