Sumario: | SIMPLE SUMMARY: The results of this large series highlight the good onco-functional results of selected pT4a laryngeal tumors treated with open partial horizontal laryngectomies (OPHL). The best cases to be treated with OPHLs are the low-volume pT4a laryngeal tumors, with minimal or absent cartilage destruction. The level of standardization of these procedures’ indications should allow consideration of open partial horizontal laryngectomy as a valid therapeutic option in case of a patient’s absolute refusal of total laryngectomy or non-surgical protocols with concomitant chemo-radiotherapy. Based also on the obtained results in the treatment of selected pT4a, such a surgical strategy should no longer be considered anecdotal. Extending the limit of resection and including a large part of the cricoid cartilage and one crico-arytenoid unit (type III OPHL + CAU) expanded the indications of type II OPHL + ARY, allowing for a safer resection of advanced and challenging laryngeal tumors. ABSTRACT: A large multi-institutional case series of laryngeal cancer (LC) T4a was carried out, including 134 cases treated with open partial horizontal laryngectomies (OPHL) +/− post-operative radiation therapy (PORT). The goal was to understand better whether OPHL can be included among the viable options in selected pT4a LC patients who refuse a standard approach, represented by total laryngectomy (TL) + PORT. All 134 patients underwent OPHL type I (supraglottic), II (supracricoid), or III (supratracheal), according to the European Laryngological Society Classification. Comparing clinical and pathological stages showed pT up-staging in 105 cases (78.4%) and pN up-staging in 19 patients (11.4%). Five-year data on overall survival, disease-specific survival, disease-free survival, freedom from laryngectomy, and laryngo-esophageal dysfunction-free survival (rate of patients surviving without a local recurrence or requiring total laryngectomy and without a feeding tube or a tracheostomy) were, respectively, 82.1%, 89.8%, 75.7%, 89.7%, and 78.3%. Overall, complications were observed in 22 cases (16.4%). Sequelae were observed in 28 patients (20.9%). No patients died during the postoperative period. This large series highlights the good onco-functional results of low-volume pT4a laryngeal tumors, with minimal or absent cartilage destruction, treated with OPHLs. The level of standardization of the indication for OPHL should allow consideration of OPHL as a valid therapeutic option in cases where the patient refuses total laryngectomy or non-surgical protocols with concomitant chemo-radiotherapy. |
