摘要
Purpose: Contralateral neck failure after therapy for squamous cell carcinoma of the oral cavity and oropharynx has rarely been studied in detail. We aimed to examine the pattern and outcome of contralateral neck relapse and possible predictive clinicopathologic factors. Patients and Methods: Seventy-three patients undergoing surgery for cancer of oral cavity/oropharynx with curative intent were recruited from the hospital head and neck cancer registry. The age, gender, tumor site, primary tumor laterality, TNM status, clinical N status, pathologic T status, ipsilateral pathologic N status, tumor stage, status of residual disease, histopathologic differentiation, postoperative radiotherapy, local relapse, distant relapse, extracapsular spread of lymph node metastasis and neck dissection were evaluated for association with contralateral neck relapse. Results: Seven patients developed ipsilateral, 5 patients developed contralateral, and 3 patients developed bilateral neck recurrence after therapy. Only 1 patient with contralateral or bilateral neck relapse survived after salvage therapy. Ipsilateral positive nodal status was the only significant clinicopathologic parameter associated with contralateral neck relapse, which occurred rather commonly in well-lateralized tumors. Conclusion: Contralateral and ipsilateral neck relapses are similar in occurrence. Pathologic positive nodal status is associated with a higher incidence of contralateral neck relapse. Aggressive and comprehensive adjuvant radiotherapy to the neck plus close surveillance in the first 2 years postoperatively might curtail the frequency and mortality due to contralateral neck failure.
