ABSTRACT
OBJECTIVES:
The optimal treatment for a substantial proportion of patients with pT1-pT2 squamous cell carcinomas of the head and neck (SCCHN) remains to be refined. The extent of surgery, role and potential benefit of adjuvant treatment are to be balanced against therapy-induced side effects. We compared the outcomes of surgery with or without adjuvant radiotherapy (RT) or chemotherapy (CRT) and investigated the prognostic value of established clinicopathological parameters.METHODS:
Data were retrospectively collected for 227 patients who were treated by surgery alone (n = 31), RT (n = 87) and CRT (n = 109) in a single center.RESULTS:
Patients with stage I/II disease who had received adjuvant RT showed a better disease-free survival (DFS) (P = 0.04) than those who had received adjuvant CRT treatment. Conversely, patients with stage III/IV disease who had received CRT showed a better overall survival (OS) (P = 0.003) and DFS (P = 0.03) than those who had received surgery alone or adjuvant RT without chemotherapy. Survival analysis demonstrated that patients with pN0 to pN1 had better OS (P = 0.02), disease-specific survival (DSS) (P = 0.003), DFS (P = 0.02) and metastases free survival (MFS) (P = 0.002) compared to patients with pN2 to pN3. Multivariate analysis showed that the pN status was an independent factor for OS (P = 0.03), DSS (P = 0.04), relapse-free survival (P = 0.03), DFS (P = 0.03).CONCLUSION:
The pN status is the most important prognostic factor for pT1 to pT2 SCCHN. Adjuvant CRT was associated with significantly better survival outcomes in patients with pN1 and pN2-3 or more advanced stage, while adjuvant RT showed significantly better outcomes in patients with pN0.Palavras-chave
