N2 - © 2018 Elsevier Inc. In chronic lymphocytic leukemia (CLL), the clinical stage has correlated with overall survival. We found that within the partial response (PR) category, changes in Binet clinical stage discriminated patients with different outcomes: those with PR-Binet A had better outcomes compared with those with PR-Binet B/C. These results suggest that in CLL patients, changes in the Binet clinical stage can be used as a complementary tool to evaluate the response to therapy. Background: To determine whether in patients with chronic lymphocytic leukemia (CLL), the clinical stage maintains prognostic significance over time and can be considered as a surrogate for the response to therapy. Patients and Methods: The data from 229 CLL patients were retrospectively evaluated. The main aims of the study were to describe the changes in clinical stage during the course of CLL as a result of the response to treatment and to determine the time to next therapy (TTNT) and overall survival (OS) according to those changes, in particular, among the heterogeneous International Workshop on CLL (IWCLL) partial response (PR) category. Results: Among the patients in the IWCLL PR category, differences were found in TTNT and OS according to the clinical stage at the response evaluation. With a median follow-up period of 91 months (range, 2-390 months), patients with a PR- Binet A at the response evaluation had significantly longer TTNT and OS compared with those with PR-Binet B/C (median TTNT, 26 vs. 11 months; P =.00; median OS, 63 vs. 43 months; P =.047). Conclusion: The results of the present study have shown that for patients with CLL, the Binet clinical stages are good outcome predictors throughout the disease course and also suggest that changes in Binet clinical stage could be useful as response surrogates and to divide the IWCLL PR category into different prognostic subgroups.
