ABSTRACT Background Sunlight has profound impacts on physical and mental health, beyond vision, including effects on circadian rhythms, alertness, mood, and sleep. A family history of any mood disorders is strongly associated with psychiatric disorders including bipolar disorder. The purpose of this study was to evaluate the association between a family history of any mood disorder in patients with bipolar I disorder and solar insolation at varied international onset locations. Methods Data for this analysis were available from 5842 patients with a diagnosis of bipolar I disorder obtained at 83 collection sites in both hemispheres. This included 4752 patients from 71 collection sites in the northern hemisphere and 1090 patients from 12 collection sites in the southern hemisphere. Patient data variables were obtained from records or interviews. Solar insolation data were obtained from The National Aeronautics and Space Administration (NASA) Power database for each onset location, and the ratio of the mean monthly minimum/mean monthly maximum solar insolation was calculated. Typically, the ratio is largest near the equator (little yearly change in solar insolation) and smallest near the poles (large yearly change in solar insolation). Results A significant relationship was found between a family history of any mood disorder, the ratio of the mean monthly minimum/mean monthly maximum solar insolation, and gender. The odds of a family history of mood disorder increased as patient location nears the poles and decreased near the equator. Female gender also increased the odds of having a family history of a mood disorder. Conclusions This study highlighted the association between family history, solar insolation, and gender in international patients with bipolar I disorder. Given the profound effects of sunlight on human health, the family of patients with bipolar disorder who live in the same location with the same solar insolation, and especially females, may be at increased risk for a mood disorder.

Background and Aims: Liver transplantation has evolved from a treatment restricted to patients with end-stage liver disease to a therapeutic option for selected patients with primary and metastatic liver malignancies. This review explores the rapidly expanding field of transplant oncology, highlighting its role in hepatocellular carcinoma, colorectal liver metastasis, neuroendocrine liver metastasis, and intrahepatic and perihilar cholangiocarcinoma. Emphasis is placed on strategies to broaden eligibility, optimize donor organ use, and improve oncologic outcomes. Approach and Results: We synthesized current evidence from clinical series, registries, and experimental protocols to evaluate patient selection criteria, outcomes, and peri-transplant management. Key topics include downstaging approaches to meet transplant criteria, such as locoregional therapies and systemic regimens, and their prognostic implications. Advances in donor utilization have been analyzed for their capacity to expand the graft pool. In addition, the review addresses the integration of oncologic principles into immunosuppression regimens, balancing graft protection with cancer control. Collectively, the reported studies demonstrate improved survival and reduced recurrence when stringent selection and multimodal therapy were applied. Conclusions: Transplant oncology reshapes the therapeutic landscape of liver malignancies, with growing evidence supporting liver transplantation in carefully selected patients beyond traditional indications. Optimized downstaging, innovative donor strategies, and tailored immunosuppression are pivotal for safe expansion. Continued collaboration between the transplant and oncology disciplines, along with prospective trials, is essential to further define standardized protocols and solidify transplantation as a cornerstone of multidisciplinary cancer care.

Abstract Objective: This study aimed to develop a machine learning model for the diagnosis of chronic renal failure (CRF) with spleen–kidney qi deficiency (SKQD) syndrome by investigating facial chromatic biomarkers based on traditional Chinese medicine (TCM) theory. Materials and Methods: This cross-sectional study analyzed TCM-defined facial regions in 303 patients with CRF (166 SKQD and 137 non-SKQD) and 25 healthy controls using active appearance models and RGB/Lab color spaces. Key chromatic features were selected using Chi-square automatic interaction detection (CHAID) decision trees to construct a multibranch deep convolutional neural network (CNN), nomogram, and hybrid model. The model performances were compared using the DeLong test. Results: The SKQD group showed a higher glomerular filtration rate, albumin level, and facial R-value with a lower serum creatinine level (all P < 0.05), accompanied by a higher prevalence of shortness of breath with reluctance to speak, and cold extremities ( P < 0.05) compared with the non-SKQD group. Chromatic analysis revealed elevated R/a values in the kidney region using the natural facial color region method ( P < 0.05), and distinctively higher R -values in the bladder-uterus region and a -values in the right small intestine region using the Mingtang facial color region method ( P < 0.05). The CHAID algorithm selected four diagnostic determinants, including the overall facial R -values. The CNN achieved superior discriminative performance (test area under the receiver operating characteristic curve = 0.74 vs. nomogram 0.68, DeLong test P < 0.001) with no added benefit from model integration ( P > 0.05). Conclusions: Facial chromatic biomarkers effectively differentiated SKQD in patients with CRF when analyzed using TCM-defined regions. The superior performance of the CNN validates AI-driven TCM diagnostics as a clinically actionable tool for precise syndrome classification.

Abstract Background: Triple-negative breast cancer (TNBC) is an aggressive yet immunogenic subtype of breast cancer (BC) and the only one with FDA-approved immune checkpoint inhibitor (ICI) - pembrolizumab. Currently, PD-L1 (22C3) is the companion biomarker for predicting pembrolizumab benefit, but its utility is limited by spatial/temporal heterogeneity, assay variability, and modest correlation with treatment response. Chemokines such as CXCL9, CXCL10, and CCL5 recruit CD8+ T cells into the tumor microenvironment and have been associated with improved response to ICI, but their predictive value alongside PD-L1 remains unclear. Here, we examined the relationship between these chemokines, PD-L1, and pembrolizumab efficacy in TNBC. Methods: We analyzed 3662 TNBC tumors profiled by NGS (592, NextSeq; WES/WTS, NovaSeq; Caris Life Sciences). Immune cells were estimated using WTS deconvolution (Quantiseq). PD-L1 positivity was defined as &gt;10% CPS (PharmDx 22C3). CXCL9/CXCL10/CCL5-high (H) and -low (L) TNBC were classified by RNA expression above or below 50th percentile. Real-world median overall survival (mOS) was derived from insurance claims and calculated from start of pembrolizumab to last contact using Kaplan-Meier. Statistical significance was assessed by chi-square and Mann-Whitney U with multiple comparison adjustments (q&lt;0.05). Results: TNBC expressed higher levels of CXCL9, CXCL10, and CCL5 (N = 3662, median TPM: 5.3, 14.8, and 15.1) compared to HER2+ (N = 1344; 4.8, 10.1, 10.6) and HR+HER2- BC (N = 6097; 2.7, 6.6, 9.4), all q&lt;0.05. Moderate correlations were observed between PD-L1 CPS and each chemokine (r = 0.41, p&lt;.01). PD-L1-positive tumors had better mOS (24.3 months (m) vs 18.6 m, HR 0.75, 95% CI 0.6-0.92, p=0.007) compared to PD-L1-negative TNBC post-pembrolizumab. Among PD-L1-negative tumors, those with CXCL9-H had better mOS (26.9 m vs 15.8 m for CXCL9-L, HR 0.61, 95% CI 0.45-0.82, p=0.001) post-pembrolizumab. Among PD-L1-positive tumors, CXCL10-H and CCL5-H was associated with improved mOS (CXCL10-H: 25.7 m vs. 20.7 m for CXC10-L, p = 0.03; CCL5-H: 26.7 vs. 18.5 m for CCL5-L, p = 0.03) post-pembrolizumab. PD-L1 negative CXCL9-H, PD-L1 positive CXCL10-H and PD-L1 positive CCL5-H groups showed higher infiltration of CD8+ T cell, B cells, M1/M2 macrophages, Tregs. They also exhibited higher T cell inflamed score, IFNy score and MAPK activation score vs. CXCL9-L, CXCL10-L and CCL5-L groups (Table). Conclusions: In TNBC, a chemokine signature comprising CXCL9, CXCL10 and CCL5 refines PD-L1 based prediction of pembrolizumab benefit. Specifically, high CXCL10 or CCL5 expression in PD-L1-positive tumors, and high CXCL9 expression in PD-L1-negative tumors, were associated with improved survival post pembrolizumab and immune-rich microenvironment. These findings support the use of chemokine profiling to complement PD-L1 and enhance patient selection for ICI therapy in TNBC. Citation Format: S. Gandhi, S. Deshmukh, S. Wu, J. Xiu, G.

Abstract Background Young age is a known risk factor for breast cancer recurrence and mortality, particularly in hormone receptor-positive disease. However, no specific evidence exists on whether age at diagnosis influences clinical behavior and outcomes among carriers of germline BRCA pathogenic or likely pathogenic variants (PVs). Methods The BRCA BCY Collaboration (NCT03673306) is an international, multicenter, hospital-based, retrospective cohort study including women with germline BRCA1 and/or BRCA2 PVs and diagnosed with stage I-III breast cancer at the age of 40 years or younger between January 2000 and December 2020. The present analysis aimed to evaluate clinical features and outcomes of breast cancer in young BRCA carriers according to age at diagnosis, by comparing patients aged ≤30 years with those aged 31-35 and 36-40 years at breast cancer diagnosis. The primary endpoint was disease-free survival (DFS). Overall survival (OS) was a secondary endpoint. Multivariable Cox proportional hazards models were used to estimate adjusted hazard ratios (aHRs), adjusting for risk-reducing mastectomy (RRM) and risk-reducing salpingo-oophorectomy (RRSO) (time-dependent), and stratifying by country, year of diagnosis, tumor size, nodal involvement, tumor grade and hormone receptor status. Results From 109 centers in 5 continents, 5350 young BRCA carriers were included, of whom 1106 (20.7%) were ≤30 years of age, 1945 (36.4%) were 31-35 years and 2299 (43.0%) were 36-40 years at the time of breast cancer diagnosis. Compared to patients aged 31-35 and 36-40 years, those aged ≤30 years were more likely to harbor BRCA1 PVs (71.3%, 62.4%, 61.1%, respectively), to present with high-grade (G3 in 71.3%, 66.6%, 65.0%, respectively), triple-negative breast cancer (56.3%, 48.1%, 46.6%, respectively), and less frequently smaller tumor size (T1: 31.7%, 36.6% and 39.5%, respectively). Consequently, chemotherapy was administered more frequently among patients aged ≤30 years (94.4%, 92.6%, 89.7%, respectively). At a median follow-up of 8.2 years (IQR, 4.7-12.8), 8-year DFS rate was 65.0% among patients aged ≤30 years, 64.7% in the 31-35 years group, and 65.8% in the 36-40 years group. No significant association between age at diagnosis and DFS outcome was observed (31-35 vs. ≤30 years: aHR 1.03, 95% CI 0.89-1.19; 36-40 vs. ≤30 years aHR 1.00, 95% CI 0.87-1.16). Similarly, no significant association between age at diagnosis and OS was observed (31-35 vs. ≤30 years: aHR 1.10, 95% CI 0.86-1.41; 36-40 vs. ≤30 years: aHR 1.11, 95% CI 0.87-1.43). Subgroup analyses by specific BRCA gene, tumor subtype, tumor size, nodal status, and chemotherapy use revealed no statistically significant interaction with age at diagnosis in terms of DFS or OS (all p for interaction &gt; 0.05). Specifically, no significant differences between age groups were observed among patients with luminal-like tumors for both DFS and OS. Conclusions In this unique international cohort of BRCA carriers diagnosed with breast cancer at a young age (≤40 years), we found no significant differences in DFS nor OS across different age groups. Notably, very young age (≤30 years) at diagnosis was not associated with worse outcomes compared to 31-35 years or 36-40 years. Age per se should not be considered a negative prognostic factor in BRCA carriers when appropriate treatment is provided. Citation Format: E. Blondeaux, A. Meacci, M. Fragío Gil, E. Klocker, F.

Abstract Background: Young BRCA carriers may undergo breast conserving surgery (BCS) or mastectomy with or without contralateral risk reducing mastectomy at the time of an index breast cancer diagnosis. A variety of factors may influence surgical decision making. Methods: The BRCA BCY Collaboration (NCT03673306) is an international, hospital-based, retrospective cohort study conducted at 109 centres across 5 continents including women with germline pathogenic or likely pathogenic variants (PV) in BRCA1/2 diagnosed between 2000 and 2020 with invasive stage I-III breast cancer prior to or at age 40 years. The primary objective of the present analysis was to evaluate surgical management in these patients. Breast surgery was defined as BCS, unilateral mastectomy, or bilateral mastectomy administered as part of primary treatment for a first diagnosis of invasive breast cancer. Multivariable logistic regression was used to determine factors associated with receipt of bilateral mastectomy. Results: Of 5660 eligible BRCA1/2 carriers, 4715 had unilateral stage I-III breast cancer with surgical treatment details available. The median age of the cohort was 35 years (IQR, 31-38 years). Overall, 1805 (38.3%) patients underwent BCS, 1752 (37.2%) underwent unilateral mastectomy, and 1158 (24.6%) underwent bilateral mastectomy. The proportion of young BRCA1/2 carriers undergoing BCS decreased over the study period (55.7% in 2000 vs. 27.0% in 2020), whereas the use of bilateral mastectomy significantly increased (8.0% in 2000 vs. 44.4% in 2020). Bilateral mastectomy was more common in women who had genetic testing performed before (57.0%) or within 6 months of a breast cancer diagnosis (38.5%), compared to those tested after diagnosis (5.1%, p&lt;0.001). On multivariable analysis, compared to those tested after diagnosis, earlier genetic testing remained the strongest predictor of bilateral mastectomy receipt (testing prior to diagnosis: OR 20.7 [95% CI 15.3-28.1]; testing at diagnosis: OR 6.8 [95% CI 5.4-8.7]). Other predictors of bilateral mastectomy receipt included geographic region, later year of diagnosis, smaller tumor size, node negative disease, and neoadjuvant treatment. In subgroup analysis including 2327 patients who had genetic testing performed before or within 6 months of diagnosis, 42.0% underwent bilateral mastectomy, with the lowest rates reported in Asia/Africa (26.1%) and the highest rates reported in North America (66.4%, p&lt;0.001). In adjusted subgroup analyses, BRCA1 PV, later year of diagnosis, smaller tumor size, node negative disease, neoadjuvant treatment, and geographic region remained independently associated with bilateral mastectomy. Conclusions: In this large, international study of young affected BRCA carriers, geographic region and timing of genetic testing strongly impacted surgical management. These data support early genetic testing for young women with breast cancer to help optimize local therapy decisions. Citation Format: S. M. Wong, E. Blondeaux, V. Delucchi, F. Coussy, R.

Background: Upfront resectable pancreatic ductal adenocarcinoma (PDAC) is defined by the NCCN as disease with ≤180° portomesenteric vein (PMV) abutment. However, the clinical significance of PMV abutment in this cohort remains unexplored, and we sought to investigate its impact. Methods: This multi-institutional study included patients who underwent pancreatoduodenectomy (PD) for upfront resectable PDAC from 2002 to 2023. Patients with PDAC with ≤180° PMV abutment were compared with those without. Overall survival (OS) was compared and stratified based on whether patients underwent upfront surgery or neoadjuvant therapy (NAT). Results: Among 1,446 patients included, 521 (36.0%) had PMV abutment. Median OS for patients with PMV abutment was 28.8 months compared with 31.2 months for those without ( P =.17). In a stratified analysis of patients who underwent upfront surgery, patients with PMV abutment had worse OS (19.2 vs 27.6 months; P <.05) and lower R0 resection rates (63.1% vs 87.2%; P <.05) compared with those without. However, in patients who underwent NAT, this difference in R0 resection rate was not observed (91.4% vs 94.0%, respectively; P =.27). Furthermore, there was no significant difference in median OS with NAT (42.5 vs 51.6 months, respectively; P =.48). Conclusions: In this largest cohort to date of patients with upfront resectable PDAC, PMV abutment was associated with worse OS compared with no PMV abutment when an upfront resection strategy was used. The use of NAT in patients with PMV abutment mitigated this survival difference with increased R0 resection rates. These findings suggest that patients with upfront resectable PDAC with PMV abutment benefit from a NAT approach for optimal survival outcomes, and that the current criteria guidelines need to be redefined.
