[Larynx-preserving pharyngoesophagectomy in the treatment of cancer of the pharyngoesophageal junction].

UNLABELLED: Pharyngo-laryngo-esophagectomy has been the sole surgical option in the management of advanced tumors arising from the pharyngoesophageal junction. This operation is associated with high morbidity, mortality and poor quality of life due to loss of larynx. The aim of the author was to achieve a reduction in tumor size by means of neoadjuvant chemoradiotherapy and so to make the tumor amenable to a larynx preserving operation avoiding pharyngo-laryngo-esophagectomy. Between 1. January 1998 and 31. December 1999, 11 consecutive patients with advanced cancer of pharyngo-esophageal junction were treated with neoadjuvant chemoradiotherapy (carboplatin, 5-fluorouracil, 30-35 Gy telecobalt irradiation). The tumor regressed in all cases and moreover, in 6 patients a larynx preserving pharyngo-esophagectomy could be carried out. This operation consists of total esophagectomy, resection of posterior pharynx wall and Akiyama-type gastric pull up with side-to-side pharyngo-gastrostomy. All 6 patients recovered. In 2 cases after neoadjuvant therapy the tumor disappeared from the cervical esophagus and so that a pharyngo-laryngectomy and free jejunum transfer could be performed. 3 other patients remained irresectable due to lymph node metastases.

CONCLUSION: Larynx preserving pharyngo-esophagectomy is a safe operation by means of which the larynx can be preserved even in those patients whose tumor is located at the level of pharyngo-esophageal junction, on the posterior wall of the pharynx.
