Non‐Hodgkin's Lymphoma of the Sinonasal Tract

Objectives A review of the presenting features, management, and outcome of extranodal non-Hodgkin's lymphoma (NHL) of the sinonasal tract during a 10-year period in Nottingham, UK. Study Design Twenty-four patients received a diagnosis of extranodal NHL of the nasal cavity, paranasal sinuses, or both, from 1987 to 1996. The patients' data were collected prospectively in the Nottinghamshire Lymphoma Registry. Methods All patients' records and their histology were reviewed along with data entered into the Nottinghamshire Lymphoma Registry, noting the patient's age, sex, presenting symptoms and signs, staging, computed tomography findings, histology, treatment, complications, and outcome. Results The 24 patients with extranodal NHL of the sinonasal tract represent 1.63% of the 1,457 patients with NHL seen in the 10-year period of this study in Nottinghamshire. The median age was 72 years (range, 42–96 y), with a male dominance (male-to-female ratio: 15:9). Most patients presented with nonspecific nasal symptoms such as nasal obstruction and epistaxis. Only one patient had a relapse involving the central nervous system after treatment. All the histology was reviewed and showed a predominance of large B-cell subtype (21 patients). The overall 5-year survival was 40% (95% CI, 19%–61%) and 33% for 10-year (95% CI, 12%–54%). The cause-specific survival at 5 years and 10 years was 62% (95% CI, 39%–86%). Conclusions A high degree of suspicion and appropriate use of computed tomography scans and surgical biopsy are the keys to the management of NHL.
