Extent of Salvage Neck Dissection in Advanced Oro- and Hypopharyngeal Cancer.

BACKGROUND/AIM: Primary radiochemotherapy (RCT) is becoming increasingly important in patients with oro- and hypopharyngeal cancer. However, debate exists on the extent of salvage neck dissection (ND) in those patients. The purpose of the present study was to evaluate the regional control after salvage ND.

PATIENTS AND

METHODS

Clinical, histological and radiological data, results of 51 patients with oro- or hypopharyngeal cancer and N2 neck who underwent selective ND in case of radiological evidence of residual neck disease, were retrospectively analyzed.

RESULTS

Altogether 52 metastases were detected in 20 (39.2%) patients by histological examination. They were localized in level II (n=23), III (n=13), IV (n=11) and V (n=5). Regional recurrence occurred in 4 patients (7.8%) in previous dissected neck levels in the follow-up.

CONCLUSION

Selective ND of suspicious neck levels for residual disease after RCT of oro- and hypopharyngeal cancer seems to be a sufficient treatment.
