Abstract

AIM:

To share experience with regional failures after selective neck dissection in both node negative and positive previously untreated patients diagnosed with squamous cell carcinoma of the oral cavity.

PATIENTS AND METHODS:

Data of 219 patients who underwent SND at Shaukat Khanum Cancer Hospital from 2003 to 2010 were retrospectively reviewed. Patient characteristics, treatment modalities, and regional failures were assessed. Expected 5-year regional control was calculated and prognostic factors were determined.

RESULTS:

Median follow-up was 29 (9-109) months. Common sites were anterior tongue in 159 and buccal mucosa in 22 patients. Pathological nodal stage was N0 in 114, N1 in 32, N2b in 67, and N2c in 5 patients. Fourteen (6%) patients failed in clinically node negative neck while 8 (4%) failed in clinically node positive patients. Out of 22 total regional failures, primary tumor origin was from tongue in 16 (73%) patients. Expected 5-year regional control was 95% and 81% for N0 and N+ disease, respectively (P < 0.0001). Only 13% patients with well differentiated, T1 tumors in cN0 neck were pathologically node positive.

CONCLUSIONS:

Selective neck dissection yields acceptable results for regional management of oral squamous cell carcinoma. Wait and see policy may be effective in a selected subgroup of patients.
