Article Abstract
Background: Neoadjuvant chemoimmunotherapy (nCIT) has shown promise in treating early-stage triple-negative breast cancer (eTNBC), but predictive biomarkers for pathological response and prognosis remain poorly defined.
Objective: This study aimed to explore pathological complete response and prognostic predictive factors in eTNBC patients treated with nCIT.
Materials And Methods: We retrospectively analyzed 112 eTNBC patients who underwent surgery after nCIT at Sun Yat-sen University Cancer Center between June 2019 and June 2023. Pathological response was assessed using Miller-Payne grade. Clinicopathological features and hematologic markers were analyzed with univariate and multivariate logistic regression or Cox regression, as well as Kaplan-Meier survival curves. Objective response rate (ORR), pathological complete response (pCR), and disease-free survival (DFS) were evaluated. Nomograms predicting pCR and DFS were constructed based on significant risk factors and the systemic inflammatory response index (SIRI).
Results: Higher baseline lymphocyte counts (=0.004) were independently associated with a higher pCR rate, while elevated monocyte counts (=0.006), neutrophil-to-lymphocyte ratio (=0.005), platelet-to-lymphocyte ratio (p = 0.005), SIRI (=0.037), systemic immune-inflammation index (=0.029), and preoperative SIRI (=0.010) were associated with a lower pCR rate. Higher baseline SIRI (= 0.009) was correlated with shorter DFS, while higher preoperative lymphocyte counts (=0.019) predicted longer DFS. Nomograms incorporating SIRI showed high accuracy in predicting pCR and DFS.
Conclusion: Hematologic inflammatory markers, particularly SIRI, are cost-effective and reliable predictors of prognosis and treatment efficacy in eTNBC patients undergoing nCIT, helping clinicians develop personalized treatment strategies.

Misophonia is a condition characterized by intense negative emotional reactions to trigger sounds and related stimuli. In this study, adult listeners (N = 15) with a self-reported history of misophonia symptoms and a control group without misophonia (N = 15) completed listening judgements of recorded misophonia trigger stimuli using a standard scale. Participants also completed an established questionnaire of misophonia symptoms, the Misophonia Questionnaire (MQ).

Background: IgA nephropathy is a disease with a highly variable natural history, for which there is an increasing understanding of the role of complement activation in its pathogenesis and progression. We aimed to assess the clinical and prognostic implications of C4d staining in the kidney biopsy of IgA nephropathy patients.
Methods: This was a retrospective observational study wherein the medical records of IgA nephropathy patients were reviewed and baseline characteristics, kidney biopsy findings, treatment response and follow-up data were noted.

Purpose: Breast cancer (BC) is the most frequent cancer among women and the second leading cause of central nervous system (CNS) metastases. While the epidemiology of CNS metastases from BC has been well described, little is known about the treatment patterns and outcomes of young women < 40 years of age with BC that is metastatic to the CNS.
Methods: In this retrospective analysis, we identified patients with metastatic breast cancer (MBC) to the CNS who were treated at the Sunnybrook Odette Cancer Center, Toronto, Canada between 2008 and 2018.

Purpose: To clarify the preferred timing and contents of early palliative care and preference for continued care delivery among patients with advanced cancer in Japan.
Methods: We conducted an Internet-based anonymous questionnaire survey on adult patients with advanced cancer. We assessed the patients' wishes for palliative care delivered by a team or at outpatient clinics while asymptomatic, as well as the preferred intervention timing and preference for continuing care lifelong.
