The treatment landscape of invasive early-stage and metastatic breast cancer is evolving constantly. These NCCN Guidelines Insights focus on recent updates included in the most recent version (version 5.2025) of the NCCN Guidelines for Breast Cancer specific to workup, locoregional therapy, surveillance, and systemic neoadjuvant/adjuvant therapy recommendations for invasive, nonmetastatic breast cancer.

The NCCN Guidelines for Prostate Cancer provide a framework on which to base decisions for patients with prostate cancer across the disease spectrum. The Guidelines sections included in this article focus on metastatic castration-sensitive prostate cancer (mCSPC), nonmetastatic castration-resistant prostate cancer (CRPC), and metastatic CRPC (mCRPC). For patients with mCSPC, disease characteristics, such as whether metastases arose synchronously or metachronously and the degree of metastatic burden, impact therapy decisions, including how much treatment intensification is appropriate and when prostate-directed and/or metastasis-directed therapy should be considered. In the mCRPC setting, androgen deprivation therapy is continued with the sequential or concurrent addition of certain androgen receptor pathway inhibitors, chemotherapies, immunotherapies, radiopharmaceuticals, and/or targeted therapies. The NCCN Prostate Cancer Panel emphasizes a shared decision-making approach in all disease settings based on patient preferences, prior treatment exposures, biomarkers, the extent and location of metastases, symptoms, and potential side effects.

ABSTRACT Pulmonary hypertension due to interstitial lung disease (PH‐ILD) is associated with high morbidity and mortality. Real‐world patients initiating inhaled treprostinil are not well‐characterized. This retrospective cohort study aimed to evaluate healthcare resource utilization in patients with PH‐ILD who initiated treatment with inhaled treprostinil vs patients who remained untreated. Adult patients diagnosed with PH‐ILD were indexed on initiation of inhaled treprostinil and patients who remained untreated were indexed on first observed PH diagnosis (31 March 2021–30 September 2024). Patients were excluded if they were ever treated with any pulmonary arterial hypertension therapy. Inhaled treprostinil patients were matched to up to four untreated patients. All‐cause per‐patient per‐month (PPPM) hospitalizations and ICU‐related hospitalizations were the primary outcomes of interest. 294 patients treated with inhaled treprostinil and 736 untreated patients were identified. Mean all‐cause PPPM hospitalizations remained unchanged in the pre‐index vs post‐index periods in the inhaled treprostinil cohort (0.11 vs 0.12; p = 0.42) but significantly increased in untreated patients (0.12 vs 0.23; p < 0.01). ICU utilization also remained unchanged in the pre‐index vs post‐index periods for the inhaled treprostinil cohort (0.06 vs 0.07; p = 0.11) compared to the untreated cohort (0.06 vs 0.13; p < 0.01). Untreated patients had significantly higher post‐index PPPM hospitalizations ( p < 0.01) and ICU utilization ( p < 0.01) compared to inhaled treprostinil patients. Patients who initiated inhaled treprostinil had a 30% decreased risk of hospitalization compared to untreated patients (relative risk: 0.70; 95% CI: 0.59–0.83; p < 0.01). Among real‐world patients with PH‐ILD, treatment with inhaled treprostinil is associated with fewer all‐cause hospitalizations and ICU‐related hospitalizations compared to untreated patients with PH‐ILD.

Objective To examine real‐world patterns in pain management among adults with systemic lupus erythematosus (SLE), we focused on the sequencing of pain modalities, polypharmacy, and demographic variation. Methods We conducted a retrospective analysis of electronic health records from adults with SLE treated at a single academic medical center between 2005 and 2024. We included patients who received at least one pain‐related therapy, including glucocorticoids, opioids, nonsteroidal anti‐inflammatory drugs (NSAIDs), antidepressants, anticonvulsants, muscle relaxants, and nonpharmacologic interventions. We used sequence analysis and Sankey diagrams to map treatment trajectories and compared patterns across two periods: 2005 to 2014 and 2015 to 2024. Polypharmacy was defined as receiving five or more pain‐related prescriptions within 12 months. We examined trends by age, sex, and race or ethnicity. Results Among 769 patients, initiation of glucocorticoids and opioids declined over time (58%–51% and 28%–22%, respectively), whereas NSAID use increased (19%–29%). The median number of pain prescriptions decreased, and polypharmacy prevalence dropped from 53% to 45%. In recent years, younger adults and men received more prescriptions, with 69% of men receiving five or more compared with 43% of women. Racial disparities narrowed overall in recent years but persisted in sensitivity analyses excluding glucocorticoids. Conclusion Pain management in SLE is shifting away from high‐risk therapies; however, prescribing intensity remains high and varies by demographic group. Visualizations serve as a complementary lens to traditional prescription counts, allowing representation of polypharmacy not only by volume but also by the diversity and sequencing of therapeutic classes over time.

Importance Primary brain and central nervous system cancer (collectively referred to as CNS cancer) comprises 2% of all human cancers and poses significant health and economic challenges in the United States. Objective To analyze CNS cancer burden in the US, stratified by time, location (state and division), sex, age group, and Sociodemographic Index (SDI). Design, Setting, and Participants This cross-sectional study involved a repeated analysis of Global Burden of Disease Study (GBD) 2021 data in 2024. Using data from 183 sources, CNS cancer metrics in the US were estimated across states and years. US CNS cancer metrics across all sexes and age groups were included in the GBD. Exposure CNS cancer diagnosis. Main Outcomes and Measures Overall and age-standardized estimates of the incidence, prevalence, mortality, disability-adjusted life-years (DALYs), years of life lost, and years lived with disability per 100 000 population, including 95% uncertainty intervals (UIs), and time trends. Results In 2021, for all age groups and sexes across the US, there were 31 780 incident cases (95% UI, 29971.1 to 32843.9). Age-standardized incidence, DALYs, and mortality rates per 100 000 population were 6.91 (95% UI, 6.58 to 7.12), 134.38 (95% UI, 129.83 to 137.95), and 4.1 (95% UI, 3.87 to 4.22), respectively. Despite no significant change observed in the overall incidence between 1990 and 2021, DALY and mortality rates decreased by 15.77% (95% UI, −17.75% to −13.68%) and 8.41% (95% UI, −11.09% to −6.22%), respectively. Substantial geographic variability was noted. Mississippi, Alabama, Kentucky, and Kansas (West North Central and East South Central divisions) and West Virginia faced persistently high burdens over the past 30 years. Sex differences were evident; disease burden was consistently higher in males compared with females. Age-specific estimates showed a bimodal distribution: the youngest group (&amp;lt;5 years) showed a significant decrease in incidence rate (−34.42% to −11.56%), whereas older age groups (&amp;gt;70 years) experienced increasing trends. DALYs and mortality rates were negatively correlated with SDI (ρ = −0.6860 and ρ = −0.6391; P &amp;lt; .001). Conclusions and Relevance These findings provide valuable insights into the CNS cancer burden across the US by age, sex, location, and SDI, enabling better public health status assessments, health care policy restructuring, and resource redistribution for improved care.

Background: Breast cancer polygenic risk scores (PRS) and traditional risk models (e.g., the Gail model [Gail]) are known to contribute largely independent information, but it is unclear how the overlap varies by ancestry, age, disease type (invasive breast cancer, DCIS), and risk threshold. Methods: In a retrospective case–control study, we evaluated risk prediction performance in 180,398 women (161,849 of European ancestry; 18,549 of Asian ancestry). Odds ratios (ORs) from logistic regression models and the area under the receiver operating characteristic curve (AUC) were estimated. Results: PRS for invasive disease showed a stronger association in younger (<50 years) women (OR = 2.51, AUC = 0.622) than in women ≥ 50 years (OR = 2.06, AUC = 0.653) of European ancestry. PRS performance in Asians was lower (OR range = 1.62–1.64, AUC = 0.551–0.600). Gail performance was modest across groups and poor in younger Asian women (OR = 0.94–0.99, AUC = 0.523–0.533). Age interactions were observed for both PRS (p < 0.001) and Gail (p < 0.001) in Europeans, whereas in Asians, age interaction was observed only for Gail (invasive: p < 0.001; DCIS: p = 0.002). PRS identified more high-risk individuals than Gail in Asian populations, especially ≥50 years, while Gail identified more in Europeans. Overlap between PRS, Gail, and family history was limited at higher thresholds. Calibration analysis, comparing empirical and model-based ROC curves, showed divergence for both PRS and Gail (p < 0.001), which indicates miscalibration. In Europeans, family history and prior biopsies drove Gail discrimination. In younger Asians, age at first live birth was influential. Conclusions: PRS adds value to risk stratification beyond traditional tools, especially in younger women and Asian ancestry populations.

BACKGROUND: The association between breast cancer diagnosis, treatment, and the risk of incident ischemic stroke remains unclear. We aimed to investigate ischemic stroke risk among breast cancer survivors and evaluate the association by age, follow-up duration, and cancer treatments. METHODS: Using the Korean National Health Insurance Service database, we studied 113,232 women newly diagnosed with breast cancer (aged ≥18 years) without prior stroke history who underwent breast cancer surgery between January 2010 and December 2016. Each was matched 1:3 by birth year to a cancer-free female population (n=322,818). Subdistribution hazard ratios (sHRs) and 95% confidence intervals (CIs) were estimated, accounting for death as a competing risk and adjusting for sociodemographic factors and cardiovascular and noncardiovascular comorbidities. RESULTS: Over a mean follow-up of 7.2 years, ischemic stroke occurred in 1,155 (1.0%) breast cancer surgery survivors. Overall, breast cancer survivors had a slightly lower risk of stroke than cancer-free women (sHR 0.94; 95% CI 0.88–1.00). However, stroke risk was elevated in the short term following diagnosis (sHR 1.59, 95% CI 1.34–1.89 at 1 year; sHR 1.17, 95% CI 1.05–1.30 at 3 years) across all age groups, with stronger associations observed at 3 and 6 months post-diagnosis. A reduced risk was observed after 1 year in a landmark analysis that included only individuals event-free at the 1-year follow-up (sHR 0.87, 95% CI 0.81–0.93). Among breast cancer survivors, treatment with anthracycline (sHR 1.25) and the combination of tamoxifen and aromatase inhibitors (sHR 1.49) were associated with increased stroke risk, whereas radiation therapy was associated with decreased risk (sHR 0.84). These associations weakened and became nonsignificant after 1 year. Stroke risk was also higher in breast cancer survivors with low income, hypertension, diabetes, or current smoking. CONCLUSION: The association between breast cancer and ischemic stroke risk is time-dependent, with increased short-term risk post-diagnosis and treatment, followed by a decline over time. These findings highlight the importance of proactive stroke risk management, including baseline cardiovascular assessments and ongoing monitoring for thromboembolic events.
