Aggressive sino-nasal non-Hodgkin's lymphoma diagnosed in Nottinghamshire, UK, between 1987 and 1996.

Abstract In the 10-year period 1987 to 1996, 24 patients were diagnosed with aggressive non-Hodgkin's lymphoma of the nasal cavities or paranasal sinuses. The disease occurred in a relatively elderly population of median age 72 years (range 42 to 96) with a male predominance (male 15; female nine). The histology on review was mostly of the large B-cell subtype (21 patients); peripheral T-cell subtype (one), anaplastic large cell of T-cell type (one) and T/natural killer cell nasal lymphoma (one). The disease was localized in 20 patients (Stage I E A). The overall survival at 5 years was 40% (95% confidence interval (CI) 19–61); at 10 years it was 33% (95% CI 12–54). The cause-specific survival (excluding deaths from causes other than lymphoma) at 5 years and 10 years was 62% (95% CI 39–86).
