Abstract
This study determined the clinical characteristics and prognosis for patients with extranodal nasal-type natural killer/T-cell lymphoma (NKTCL) with secondary cutaneous involvement. Twenty-eight patients with NKTCL of the upper aerodigestive tract with secondary cutaneous involvement were reviewed. The median overall survival (OS) was 21.5 months from the first diagnosis, and 12.3 months from the presentation of a cutaneous lesion. The 5-year OS rate was 43.1% (median, 28 months) for patients with localized cutaneous disease compared with 0% (median, 3.6 months) for generalized cutaneous disease (p = 0.017). The 2-year OS rates were 67.5% for patients who achieved a complete response (CR) compared with 19.4% (median, 5.2 months) for patients who did not (p = 0.003). Patients with NKTCL with secondary cutaneous dissemination overall have a poor prognosis, but a relatively favorable prognosis was identified for the small subgroup of patients who had localized cutaneous lesions and achieved a CR.
