Subtotal pharyngolaryngectomy conservation surgery for carcinoma of sinus pyriformis extending toward the larynx

A novel surgical approach for hypopharyngeal carcinoma resection via the paraglottic space

Background

Conservative surgery has proven advantageous in controlling hypopharyngeal squamous cell carcinoma (HSCC) and preserving speech and swallowing function in carefully selected patients, typically with early T-stages diseases. A variety of modified surgical procedures or techniques have been proposed.

Methods

In this study, we present a novel surgical approach for hypopharyngeal carcinoma resection utilizing the paraglottic space.

Results

The paraglottic space approach can help expose neoplasms under direct vision and save mucosa during surgery while sufficiently preserving laryngeal function, thus benefiting postoperative swallowing and reducing complications. A large cohort of 426 patients with HSCC underwent surgical treatment at our institution using this approach, demonstrating an overall survival (OS) rate of 52.3% and low incidences of postoperative complications.

Conclusions

This surgical approach can be applied in patients with the lesions that do not involve the paraglottic space.

Primary radiotherapy for squamous cell carcinoma of the pyriform sinus

The objective of this study is to report the long-term outcomes of primary radiotherapy (RT) for patients with T1-T2 squamous cell carcinomas (SCC) of the pyriform sinus. Between November 1964 and March 2008, 135 patients with T1-T2 pyriform sinus SCC were treated with primary RT at the University of Florida. Adjuvant chemotherapy was employed in 21 patients (16 %) and 62 patients (46 %) underwent a planned neck dissection. Median follow-up was 3.5 years (range 0.2-24.7 years); median follow-up on living patients was 8.3 years (range 3.8-24.0 years). The 5-year outcomes were as follows: local control, 85 %; regional control, 81 %; local-regional control, 71 %; distant metastasis-free survival, 76 %; cause-specific survival, 62 %; and overall survival, 38 %. The 5-year local control rate was 88 % for T1 cancers and 84 % for those with T2 SCCs (p = 0.5429). Sixteen patients (12 %) experienced severe late complications. Primary RT results in a high probability of cure with a relatively modest risk of severe late complications for patients with T1-T2 SCCs of the pyriform sinus.

Squamous carcinoma of the head and neck: the untreated patient

One thousand, nine hundred and seventy-seven patients with squamous carcinoma of the head and neck are reviewed with particular reference to the patients not treated. The commonest reason for not treating the patients was that the tumour was too extensive (55%). A further 36% were too old or infirm to be considered fit for radical treatment, and 9% of patients refused treatment. Treated and untreated patients were compared for age, sex, site of the primary and TNM stage. The proportion of patients untreated varied according to site of the primary tumour, with 25% of pharangeal tumours being the highest proportional representation. Median survival for untreated patients was 88 days; survival time was significantly related to sex, T stage of primary tumour and patient's general condition.
