Purpose
This study aimed to investigate the clinical factors associated with breast cancer (BRCA) dural metastases (DMs), their impact on prognosis compared to brain parenchymal metastases (BPMs) alone, and differences between DM subtypes, aiming to inform clinical decisions.
Materials and Methods
We retrospectively analyzed 119 patients with BRCA with brain metastasis, including 91 patients with BPM alone and 28 patients with DM. Univariate and multivariate analyses were performed to compare the clinical characteristics between the two groups and within subtypes of DM. Overall survival after DM (OSDM) and the interval from DM to leptomeningeal carcinomatosis (LMC) were compared using Kaplan-Meier analysis.
Results
DM was notably linked with extracranial metastasis, luminal-like BRCA subtype (p=0.033), and skull metastases (p < 0.001). Multiple logistic regression revealed a strong association of DM with extracranial and skull metastases, but not with subtype or hormone receptor status. Patients with DM did not show survival differences compared with patients with BPM alone. In the subgroup analysis, nodular-type DM correlated with human epidermal growth factor receptor 2 status (p=0.044), whereas diffuse-type DM was significantly associated with a higher prevalence of the luminal-like subtype (p=0.048) and the presence of skull metastasis (p=0.002). Patients with diffuse DM did not exhibit a significant difference in OSDM but had a notably shorter interval from DM to LMC compared to those with nodular DM (p=0.049).
Conclusion
While the impact of DM on the overall prognosis of patients with BRCA is minimal, our findings underscore distinct characteristics and prognostic outcomes within DM subgroups.

Purpose
The presentations and geographic incidence of pediatric non-Hodgkin lymphoma (NHL) differ from those of adults. This study delineated the characteristics and outcomes of pediatric NHL in East Asia.
Materials and Methods
Medical records of 749 pediatric patients with NHL treated at participating institutions in mainland China, Japan, Korea, and Taiwan from January 2008 to December 2013 were reviewed. Demographic and clinical features, survival outcomes, and putative prognostic factors were analyzed.
Results
Five hundred thirty patients (71%) were male. The most common pathologic subtypes were Burkitt lymphoma (BL) (36%). Six hundred seven patients (81%) had advanced diseases at diagnosis. The 5-year overall survival and event-free survival (EFS) rates were 89% and 84%. The 5-year EFS rates of BL, lymphoblastic lymphoma, and diffuse large B-cell lymphoma were 88%, 88%, and 89%, and those of anaplastic large cell lymphoma (ALCL) and peripheral T-cell lymphoma (PTCL) were 71% and 56% (p < 0.001). Central nervous system involvement, high lactate dehydrogenase level (> 250 IU/mL), and advanced disease at diagnosis (≥ stage III) were associated with poor outcomes (p < 0.05). ALCL and PTCL relapsed more frequently than other pathologic subtypes (p < 0.001).
Conclusion
In East Asia, PTCL was more frequent than in Western countries, and bone marrow involvement did not affect treatment outcome. This international study should motivate future collaborative study on NHL in East Asia.
