  1. Wojciech K. Mydlarz, M.D. “Pharyngocutaneous Fistulas after Salvage Laryngectomy: Need for Vascularized Tissue”

  2. Disclosures No Relevant Financial Relationships or Commercial Interests

  3. Educational Objectives Discuss risk factors for fistula after salvage total laryngectomy Discuss prevention of fistulas after salvage total laryngectomy Discuss outcomes and complications of various surgical management options of fistulas.

  4. Overview Background Risk factors for pharyngocutaneous fistulas (PCF) after Salvage Total Laryngectomy (TL) Prevention of PCF after Salvage TL: vascularized tissue Outcomes

  5. Clinical Background • Laryngeal Cancer: • Supraglottis (epiglottis, arytenoids, aryepiglottic folds, false cords) • Glottis (true cords, anterior and posterior commissures) • Subglottis

  6. Clinical Background2006 ASCO New cases of laryngeal cancer to be diagnosed (U.S., 2005): 9,880 Newly diagnosed cases that will lead to death (U.S., 2005): 3,770 95% of laryngeal cancers are invasive with squamous cell carcinoma as the predominant histologictype 40% of patients will have stage III or IV laryngeal cancer (upon first evaluation) 25% of healthy people are willing to trade a 20% absolute difference in survival for the opportunity to save their voice

  7. Clinical Background Tobacco and/or alcohol use are associated with most cases of laryngeal cancer Continued tobacco and/or alcohol use complicates treatment and facilitates medical comorbidity and the development of second primary cancers.

  8. Clinical Background • Larynx-preservation options include: • Radiation therapy • Chemoradiation therapy • Function-preserving partial laryngectomyprocedures • TL is surgical procedure most feared by patients. Common sequelae: • Social isolation • Job loss • Depression

  9. Clinical Scenario 54 year-old man s/p 35 doses of 2 Gray RT over 7 weeks for a T3NOMO squamous cell carcinoma of the right vocal cord 6 months later undergoes biopsy because of suspicion of recurrence. PMH significant for non–insulin-dependent diabetes mellitus and hypertension. Patient continues to smoke 10 cigarettes per day, which has decreased from 25 cigarettes per day before diagnosis of laryngeal cancer. He consumes about 4 beers per day. Biopsy histopathology positive for residual tumor. Multidisciplinary oncology board recommends salvage TL surgery. Potential complications of TL discussed with patient, including PCF. The patient asks about what are his risks for a fistula?

PCF After Total LaryngectomyAarts MCJ et al. “Salvage Laryngectomy After Primary Radiotherapy: What Are Prognostic Factors for the Development of Pharyngocutaneous Fistulae?” Otolaryngology–Head and Neck Surgery 144(1) 5–9 • multivariate logistic regression analysis: only initial T stage & tumor site remained as independent prognostic factors • Odds ratio (OR) for tumor stage: • 2.08 (95% confidence interval [CI] = 1.26-3.45) • T3-4 in comparison to T1-2 for developing PCF • OR for tumor site: • 2.08 (95% CI = 1.25-3.45) • Non-glottictumors in comparison with glottic tumors.

  33. Summary PCF can occurr after salvage TL Previous radiotherapy, tumor location and T stage are important risk factors Vascularized tissue plays a role in prevention of PCF after Salvage TL Pectoralis major and free flaps can both be used to help prevent PCF with good outcomes
