Analysis of primary CD30+ cutaneous lymphoproliferative disease and survival from the Surveillance, Epidemiology, and End Results database.
OBJECTIVE
Primary CD30+ cutaneous lymphoproliferative disease (PCLPD) is a spectrum of indolent cutaneous T-cell lymphomas. The primary intention of the analysis of the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) database was to report epidemiologic information and overall survival of patients with PCLPD.


METHODS
We investigated the SEER database from 1973 to 2004 and performed univariable and multivariable survival analysis.


RESULTS
A total of 268 cases of PCLPD were recorded from 1973 to 2004. Median age at diagnosis was 61 years (range, 5 to 98 years). Among cases, 58% were male, and 42% female. Race distribution was 87% white, 7% black, and 4% Asian/Pacific Islander. A total of 157 patients had primary, localized PCLPD. For the total population (N = 268), overall survival at 3 years was 81% (95% CI, 74% to 87%). Population-matched relative survival at 3 years was 87% (SE, 3.6%). Disease-specific survival at 5 years was 92% (95% CI, 86% to 95%). Head and neck skin site predicted for inferior overall survival in patients with primary, localized PCLPD on univariable analysis (hazard ratio [HR] = 4.4; P = .008; 95% CI, 1.5 to 13.2), and was suggestive of decreased overall survival on multivariate analysis (HR = 3.0; P = .06; 95% CI, 0.95 to 9.7).


CONCLUSIONS
Localized PCLPDs are rare diseases with an excellent overall survival and occur more frequently in whites and in men. Head and neck skin primary site may be associated with poorer survival. CONCLUSIONS regarding subsets demonstrating association with survival should be taken with caution, given the small number of deaths analyzed.
