[Stomal Cancer Recurrency, A Clinic-Pathological Consideration]

Objectives: Analysis of pre-operative tracheostomy and circumjacent tumour free margins as risk factors in the development of stomal recurrent disease after (pharyngo)laryngectomy. Material and Methods: 124 patients after (pharyngo)laryngectomy were analyzed for disease related data and tumour samples were analyzed for tumour free margins. The overall cohort was divided into patients with/withour pre-operative tracheostomy. Results: 18 patients suffered from recurrent disease (10 stomal, 8 distant metastases). Advanced T-status, female gender, and sub-/glottic tumour manifestation resulted in a higher rate of prior tracheostomy. Pre-operative tracheostomy did not influence the development of stomal recurrency. R0 resection was achieved in 94% of our patients, with significant reduced tumour free margins in patients with stomal recurrency (p=0.002) Conclusion: Pre-operative tracheostomy did not influence the development of stomal recurrent disease. The clinical identification of ventral soft tissue infiltration should result in extensive surgical concepts.
