A review of 150 cases of mid-face skin cancers treated by the fresh tissue technique of microscopic controlled excision has revealed local epithelial cancer spread to be markedly influenced by embryological fusion planes. Knowledge of facial embryology which is reviewed in this article should allow the surgeon to better predict and treat mid-facial skin cancer.

The Voice Button is a simple biflanged silicone device placed in the tracheoesophageal wall which has been found to enable speech without aspiration in approximately 80% of unselected laryngectomy patients. A simple surgical outpatient procedure provides the necessary tracheoesophageal fistula for insertion of the Voice Button. Indications, results, advantages, disadvantages and complications are discussed.

A retrospective analysis was performed to investigate potential prognostic factors for complete remission to neoadjuvant chemotherapy and overall survival in patients with previously untreated stage III and stage IV head and neck cancer. Eighty consecutive patients were treated in one of two studies investigating three or four courses of neoadjuvant chemotherapy. Before local therapy and surgery and/or radiotherapy, 29% attained a complete remission. No strong significant and independent predictor of complete remission was identified. Only nodal stage (N) was found moderately associated with complete remission (p = 0.06). Node-negative patients had higher remission rates. Less important predictors were tumor stage (T) and site of disease; nasopharyngeal patients had superior remission rates (56%). With a median followup of 45 months and estimated 3-year survival rate of 38% (median 23.7 months), individual factors predictive of survival included pretherapy weight loss, performance status, alcohol use, pretherapy serum albumin level, site of disease, and N stage. In multivariate testing weight loss was identified as the strongest independent predictor of survival (p less than 0.0001) and surpassed other health status measures, such as performance status and serum albumin level. In addition, N stage (p = 0.019) and alcohol use (p = 0.017) were found to be predictive. A cross-classification by N stage and weight loss revealed risk groups with distinctly different prognoses, which may be useful for design and analysis in future trials.

We found EPT to be safe and efficacious in patients with head and neck cancer, even with internal carotid artery involvement. Patients with early stage recurrences have the potential for prolonged survival beyond 2 years without the morbidity of surgery and radiation or toxicity of systemic chemotherapy. Because of its superb access qualities even for bulky tumors, EPT is a potential method of delivery for other tumoricidal agents such as in genetic-altering schemes.
