ABSTRACT
OBJECTIVE:
To investigate the prognostic value of initial characteristics including blood eosinophilia in patients with primary cutaneous T-cell lymphoma.DESIGN:
A retrospective inception cohort, patients included from date of diagnosis (1982-1998).SETTING:
Two dermatology departments of a university hospital. Patients A total of 104 patients with cutaneous T-cell lymphoma, including patients with mycosis fungoides (n = 69), Sézary syndrome (n = 13), and nonepidermotropic cutaneous lymphoma (n = 22). The following variables were recorded age, sex, diagnosis according to the European Organization for Research and Treatment of Cancer (EORTC) classification, type of skin involvement at the time of diagnosis, initial eosinophil absolute count, lactate dehydrogenase value, date of disease progression, and cause and date of death or date of last contact. MAIN OUTCOMEMEASURES:
Time from diagnosis to disease progression and to disease-specific death.RESULTS:
The median follow-up was 43 months (range, 7-197 months). Estimated rates of disease progression and disease-specific death for 3 years were 19.5% (95% confidence interval [CI],11.3%-27.6%) and 9.9% (95% CI, 2.8%-13.6%), respectively. Univariable analysis of initial variables possibly influencing disease progression revealed significant prognostic value for diagnosis according to EORTC classification (hazard ratio [HR], 2.77; 95% CI, 1.04-7.41; P =.04), type of skin involvement (HR, 2.70; 95% CI, 1.00-7.25; P =.04), raised blood eosinophil absolute count (HR, 7.33; 95% CI, 2.84-18.91; P<.001), and raised serum level of lactate dehydrogenase (HR, 3.72; 95% CI, 1.58-8.78; P =.001). Concerning disease-specific death, significant prognostic indicators were diagnosis according to the EORTC classification (HR, 6.62; 95% CI, 1.68-26.12; P =.007) and a raised blood eosinophil absolute count (HR, 10.57; 95% CI, 2.28-49.0; P<.001). In multivariable analysis, only blood eosinophilia was associated with disease progression and disease-specific death.CONCLUSION:
These results strongly suggest that blood eosinophilia at baseline is a prognostic factor in patients with primary cutaneous T-cell lymphoma.
