A population-based survey was conducted in northern Finland in order to study the incidence rate and survival in patients with pharyngeal cancer diagnosed between 1986 to 1996. A total of 95 new patients with hypopharyngeal, oropharyngeal or nasopharyngeal cancers were identified. The overall age-adjusted incidence rates (per 100,000 years) were 1.28 in men and 0.60 in women, giving an overall incidence rate of 0.89. Most of the tumours were diagnosed at stage IV, and the median disease-specific survival times were 27.6 months for the patients with oropharyngeal cancer, 13.5 months for nasopharyngeal cancer and 17.7 for hypopharyngeal cancer. The most important factors that were associated with a poor prognosis were stage IV in oropharyngeal [Hazard ratio (HR) 3.68, 95% confidence interval (CI) 0.97-13.92] and hypopharyngeal cancer (HR 3.99, CI 1.51-10.67) and age over 65 years in nasopharyngeal cancer (HR 9.28, CI 1.79-47.99).

A population-based survey was conducted in Northern Finland to evaluate the incidence rate as well as the patient and tumor characteristics of malignant epithelial salivary gland tumors diagnosed between 1988 and 1998. A total of 40 new cases of malignant epithelial salivary gland tumors were diagnosed and separately evaluated. The age-standardized incidence rates (per 100,000 years) were 0.51 among men and 0.35 among women, giving an overall incidence rate of 0.43. About half of the patients suffered from pain, which was the most common symptom along with palpable resistance, but the duration of symptoms varied widely (median: 11 months). Of all the malignant epithelial salivary gland tumors analyzed in our study, fine-needle aspiration cytology correctly indicated malignancy in only 28% of the cases.
