BACKGROUND: To compare the usefulness of four prognostic scores in patients with peripheral T-cell lymphoma (PTCL) from a single institution.
PATIENTS AND METHODS: One hundred twenty-one patients (77 male/36 female, median age 53 years) with PTCL [anaplastic large-cell lymphoma (ALCL) 21, PTCL not otherwise specified 56 and other 44)]. Complete response (CR) rate and 5-year overall survival (OS) were 41% and 31%, respectively. International Prognostic Index (IPI), Prognostic Index for T-cell lymphoma (PIT), International peripheral T-cell lymphoma Project score (IPTCLP) and modified Prognostic Index for T-cell lymphoma (mPIT) were calculated as in the original references. mPIT was only assembled to 41 patients in whom Ki-67 immunostaining was available. ALCL patients were analyzed separately.
RESULTS: Concordance among IPI, PIT and IPTCLP was 52% for low-risk group, 27% for low/intermediate-risk group, 20% for high/intermediate-risk group and 14% for high-risk group. IPI, PIT and IPTCLP predicted CR, with IPI being the best score in logistic regression. Neither Ki-67 immunostaining nor mPIT predicted CR. Five-year OS (low-risk versus intermediate- or high-risk categories) according to IPI, PIT, IPTCLP and mPIT were 52% versus 45%, 75% versus 49%, 58% versus 20% and 39% versus 0%, respectively. IPTCLP was the best score for OS in multivariate analysis.
CONCLUSION: All the scores demonstrated their usefulness to assess the outcome of patients with PTCL, with IPTCLP being the most significant to predict OS.
