ABSTRACT
PURPOSE: Transoral robotic surgery (TORS) as a first-line therapy has been well-documented but evidence is missing regarding salvage therapy. The aim of this study is to compare the oncological and functional outcomes of TORS as a primary and salvage therapy.
METHODS: This retrospective monocentric study included 74 patients operated by a single surgeon and sorted out into two groups: primary treatment (PT) or Salvage treatment (ST) in case of previous history of radiation therapy. Patients were further stratified by tumour location: larynx and pharynx (lST vs lPT and pST vs pPT).
RESULTS: Forty-eight patients were included in PT group (64.9%) and 26 in ST group (35.1%). ST patients had more frequent cTis/T1 tumours (57.7% vs 29.2%, p = 0.0164) and no clinical lymph disease (3.8% vs 37.5%, p = 0.0016). Tracheostomy was m ore often performed in the ST group (57.7% vs 16.7%, p = 0.0003) and the lST subgroup (88.9% vs 9.1%, p < 0.0001). Gastric feeding tube placement was more frequent in the ST group (76.9% vs 33.3%, p = 0.0003), the pST subgroup (64.7% vs 15.4%, p = 0.0009) and the lST subgroup (100% vs 54.5%, p = 0.0297). We observed a trend for more postoperative complications in the ST group (69.2% vs 47.9%, p = 0.0783). The overall survival was lower in the ST group (p = 0.0004), and in the pST subgroup (p < 0.0001). The disease-free survival rate was lower in the ST group (p = 0.0001), the pST subgroup (p = 0.0002) and the lST subgroup (p = 0.0328).
CONCLUSION: This study confirms that survival and functional outcomes after salvage TORS are worse than in first line surgery.
