Non-surgical combined modality treatments for laryngeal organ preservation in advanced hypopharyngeal carcinoma / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the treatment outcome, laryngeal preservation and side-effect in locally advanced hypopharyngeal carcinoma treated with combined Hilical tomotherapy (HT) or intensity-modulated radiotherapy (IMRT) and chemotherapy and/or EGFR inhibitor (Cetuximab or Nimotuzumab).</p><p><b>METHODS</b>A total of 68 patients (20 cases with T1-2N1-3M0 and 48 cases with T3-4N1-3M0) with locally advanced hypopharyngeal cancer were treated individualy with non-surgical combined modality treatments including induction chemotherapy followed by concurrent chemoradiotherapy, induction chemotherapy followed by concurrent radiotherapy and EGFR inhibitor, concurrent chemoradiotherapy and EGFR inhibitor, and concurrent radiotherapy and EGFR inhibitor. HT was used in 40 patients and IMRT in 28 patients. Side-effects were evaluated with the established Common Terminology Criteria for Adverse Events (CTCAE) version 3.0 criteria.</p><p><b>RESULTS</b>The average follow-up time was 25.7 months (range 3-69 months). All patients completed the planned radiotherapy without treatment breaks, and 66 (97.0%) of 68 patients completed the planned chemotherapy. The 2-year and 3-year overall survival rates were 78.8% and 64.7% respectively, with an organ preservation rate of 84.2%. The most common side-effect greater than or equal to grade 3 was oropharyngeal mucositis. No patient dependent on a percutaneous gastrostomy and tracheostomy tube.</p><p><b>CONCLUSION</b>Hypopharyngeal carcinoma can be treated with non-surgical combined modality treatment including HT or IMRT, with a high laryngeal organ preservation rate and minimal toxicities.</p>
