Insights
The platelet-to-lymphocyte ratio (PLR) did not prove to be a reliable prognostic biomarker for chronic lymphocytic leukemia (CLL). Further research is needed to identify effective prognostic markers for CLL patient outcomes.
Area of Science:
- Hematology
- Oncology
- Clinical Research
Background:
- The platelet-to-lymphocyte ratio (PLR) is investigated in chronic lymphocytic leukemia (CLL) due to the involvement of platelets and lymphocytes in CLL pathogenesis.
- PLR may influence treatment decisions in CLL management.
Purpose of the Study:
- To evaluate the prognostic role of PLR in chronic lymphocytic leukemia (CLL).
- To assess the association of PLR with watchful waiting duration, postdiagnosis survival, and postchemotherapy survival in CLL patients.
Main Methods:
- Retrospective analysis of demographic and clinical data from 100 CLL patients diagnosed between 1989 and 2013.
- Cox regression models were employed to analyze the impact of PLR on clinical outcomes.
Main Results:
- Univariable analysis showed a correlation between PLR and watchful waiting duration (HR=0.48, p=0.018).
- Multivariable analysis revealed that Binet staging and lymphocyte count were significant predictors of watchful waiting duration.
- Age and lymphocyte count were identified as determinants of postdiagnosis survival.
Conclusions:
- The platelet-to-lymphocyte ratio (PLR) does not appear to be a significant prognostic biomarker for CLL.
- Established factors like Binet staging, lymphocyte count, and age are more critical in predicting CLL patient outcomes.
Aim:
The rationale for platelet-to-lymphocyte ratio (PLR) in chronic lymphocytic leukemia (CLL) is that both the platelet and lymphocyte counts are affected by the CLL pathogenesis and could influence treatment decision-making.
Methods:
Demographic and clinical data of CLL patients diagnosed at our institution between 1989 and 2013 were collected. Cox regression models were used to evaluate the role of PLR in the duration of watchful waiting, postdiagnosis survival and postchemotherapy survival.
Results:
The data of 100 patients with CLL were reviewed for this study. The PLR correlated only to watchful waiting in the univariable analysis (Hazard ratio = 0.48 [0.32-0.73]; p = 0.018). In the multivariable analysis, the duration of watchful waiting was determined by Binet staging and lymphocyte count (p < 0.001). The postdiagnosis survival was determined by age (p = 0.002) and lymphocyte count (p = 0.010).
Conclusion:
The PLR did not seem to act as a prognostic biomarker for CLL.
