To evaluate the oncologic and functional results of larynx-preserving partial pharyngectomy (LPP) via lateral pharyngotomy approach as a primary treatment for small (T1 or T2) hypopharyngeal squamous cell carcinoma (HPSCC).
We performed a retrospective review of 23 patients who underwent LPP through lateral pharyngotomy approach for small HPSCC at the our department between January 1991 and June 2007. Fourteen (61%) patients had adjuvant postoperative radiotherapy.
The 2-years and 5-years disease specific survival rate was 77% and 61%, respectively. Nine patients (39%) had tumor recurrence. The most common pattern of recurrence was isolated distant failure (n=4, 44%) followed by local (n=2, 22%) and loco-regional (n=3, 34%) recurrence. The ultimate cure rate of the primary tumor was 87% (20 of 23). Twenty-two of the 23 patients (95%) could be decannulated, tolerate an oral diet, and had acceptable postoperative phonatory function.
LPP via lateral pharyngotomy approach appears to be a feasible procedure for selected small HPSCC patients in terms of both oncologic and functional outcomes.
