ReviewCervical lymph node metastases from occult squamous cell carcinoma.
Depending on patient and tumor characteristics, reported 5-year actuarial survival rates of patients with cervical nodal metastasis from an unknown primary carcinoma range from 18% to 63%. Prognostic factors for survival include N-stage, number of nodes, grading, extracapsular extension, and performance status. Retrospective studies suggest that neck relapse is more common than are distant metastases or emergence of mucosal primary tumors. ⋯ Retrospective single-institution comparisons between comprehensive and unilateral neck radiotherapy did not show apparent differences in outcome. A randomized trial to compare the therapeutic value of comprehensive versus volume-limited radiotherapy is being planned. No data were found to support the benefit of chemotherapy for the treatment of this disease.
