The Usefulness of Total Laryngectomy in Sarcopenic Patients With Hypopharyngeal and Laryngeal Cancer.

Abstract

Sarcopenia has an adverse effect on postoperative complications and prognoses in head and neck cancer. This study focused on hypopharyngeal and laryngeal cancer patients with sarcopenia and analyzed the body composition following treatment when the larynx was preserved and when total laryngectomy was performed to examine the usefulness of laryngectomy. We retrospectively reviewed 88 primary hypopharyngeal and laryngeal cancer patients aged 65 years or older with cT2N0M0 or higher who visited our department. There were no significant differences in the 3-year overall survival rate and the 1-year local control rate between the laryngeal preservation group and laryngectomy group. The average change one year following treatment in the laryngeal preservation group, when compared to prior to treatment, was a significant decrease in the body weight (BW) of -0.035, skeletal muscle mass (SMM) of -0.030, skeletal muscle mass index (SMI) of -0.026, body mass index (BMI) of -0.034, and grip strength (GS) of -0.066. The average change one year following treatment in the laryngectomy group, compared with prior to treatment, was an increase in BW of +0.028, SMM of +0.026, SMI of +0.008, BMI of +0.032, and GS of +0.026. Although no changes in serum biochemical testing after treatment were observed in the laryngeal preservation group, albumin, transferrin, and transthyretin all exhibited significant improvement or a tendency toward improvement in the laryngectomy group. The patients with sarcopenia before treatment in the laryngeal preservation group had a significantly higher incidence of aspiration pneumonia. The presence or absence of sarcopenia before starting treatment is considered to be an index for selecting total laryngectomy.
