Objectives: It is common of chronic phase chronic myeloid leukemia (CML-CP) patients coexisting anemia at diagnosis, but the role of anemia on the prognosis is not clear. This study aims to explore impact of anemia on outcomes of CML-CP patients in TKI era. Methods: In the retrospective study, 258 newly diagnosed CML patients treated with TKIs were enrolled. Patients with moderate anemia (Hb ≤ 90 g/L) and non-moderate anemia (Hb > 90 g/L) were compared. Results: The incidence of moderate anemia at the time of CML diagnosis was 34.8%. Compared with patients with non-moderate anemia, patients with moderate anemia had higher proportion of intermediate-high Sokal risks and more aggressive characteristics such as higher WBC counts, higher percent of myeloblasts and basophils. However, there were no statistical differences in terms of optimal response rates, 5-year PFS and OS between the two groups. Conclusion: Moderate anemia is a common concomitant symptom in CML-CP patients and is associated with high-risk CML, but its occurrence does not affect the survival of CML-CP patients in TKI era.
Purpose. This study was performed to determine whether diffusion-weighted imaging (DWI) plus unenhanced computed tomography (CT) of the brain increases the diagnostic value of routine magnetic resonance (MR) imaging findings of early-stage glioblastoma. Methods. Postcontrast MR images of eight unenhanced lesions that had been pathologically diagnosed as glioblastoma were retrospectively examined. The location, margin, signal intensity, and attenuation on MR imaging and CT were assessed. Results. On MR imaging, all lesions were ill-defined, small, and isointense to hypointense on T1-weighted images and hyperintense on T2-weighted images. Four patients had perilesional edema. In seven patients, DWI showed an inhomogeneous hyperintense lesion (n = 1) or isointense lesion with a hyperintense region (n = 6). On unenhanced CT, all masses presented as a hypoattenuated lesion with a hyperattenuated region (n = 7) or isoattenuated region (n = 1). The hyperattenuated region (n = 6) or isoattenuated region (n = 1) on CT appeared on DWI as an inhomogeneous hyperintense lesion (n = 1), isointense lesion with a hyperintense region (n = 3), or ring-like peritumoral hyperintensity (n = 3). Conclusions. MR imaging was the most sensitive imaging method for depicting early-stage glioblastoma. The CT finding of a hyperattenuated or isoattenuated region combined with the DWI finding of the same region containing an inhomogeneous hyperintense lesion or isointense lesion with a hyperintense region may be a specific diagnostic sign for early-stage glioblastoma. DWI plus unenhanced CT added diagnostic value to the routine MR imaging findings of early-stage glioblastoma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
