ABSTRACT
PURPOSE: To investigate the association between time-to-surgery (TTS) and overall survival (OS), disease specific survival (DSS) and quality of life (QoL) in patients with oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS: 116 patients with OSCC candidate to surgery were examined. TTS intervals starting from diagnosis (TTS-clinical-based) and from histological reports (TTS-biopsy-based) were calculated. The effects of TTS intervals and prognostic factors on 5-year OS and DSS were explored. RESULTS: In our cohort advanced T-categories OSCCs with TTS < 30 days showed a trend to have higher DSS rate (p = 0.049). Patients with TTS-clinical-based < 30 days showed better postoperative QoL. Positive surgical margins, nodal involvement (pN+), DOI >10 mm, invasive surgery and extra-capsular extension in pN+ were found to be significantly associated with a poor OS and DSS. CONCLUSIONS: TTS ≥ 30 days can adversely affect DSS, especially in the advanced T categories. Short TTS intervals resulted associated with a better postoperative QoL.
