Objective: To investigate the impact of vasculogenic mimicry (VM) and postoperative adjuvant therapy on the prognosis and survival of patients with esophageal squamous cell carcinoma (ESCC), as well as to assess whether VM affects the clinical benefit of postoperative adjuvant therapy.
Methods: This single-center retrospective analysis included patients who underwent radical surgery for ESCC, which was documented in the medical record system. The presence or absence of VM in surgical specimens was determined using double staining with PAS/CD31. Stratification was applied based on adjuvant therapy and VM status. Survival curves and COX modeling were used to analyze the impact of the presence or absence of VM on the benefit of adjuvant therapy and the survival prognosis of patients.
Results: VM-positive patients were more prone to postoperative recurrence and metastasis. VM was identified as an independent risk factor for progression-free survival (PFS) (p < 0.001, 95% CI:1.809-3.852) and overall survival (OS) (p < 0.001, 95% CI:1.603-2.786) in postoperative ESCC. Postoperative adjuvant therapy significantly prolonged PFS (p = 0.008) and OS time (p < 0.001) in patients with stage II and III ESCC, with concurrent chemoradiotherapy being the most effective. However, the presence of VM significantly reduced the benefits of postoperative adjuvant therapy (p < 0.001).
Conclusion: VM negatively impacts the prognosis of postoperative ESCC patients and reduces the efficacy of postoperative adjuvant therapy.

An Activin Receptor-Like Kinase 1-governed monocytic lineage shapes an immunosuppressive landscape in breast cancer metastases.

The biology centered around the TGF-beta type I receptor Activin Receptor-Like Kinase (ALK)1 (encoded by ACVRL1) has been almost exclusively based on its reported endothelial expression pattern since its first functional characterization more than two decades ago. Here, in efforts to better define the therapeutic context in which to use ALK1 inhibitors, we uncover a population of tumor-associated macrophages (TAMs) that, by virtue of their unanticipated Acvrl1 expression, are effector targets for adjuvant anti-angiogenic immunotherapy in mouse models of metastatic breast cancer. The combinatorial benefit depended on ALK1-mediated modulation of the differentiation potential of bone marrow-derived granulocyte-macrophage progenitors, the release of CD14+ monocytes into circulation, and their eventual extravasation.

Background: The therapeutic targeting of the intestinal microbiota has gained increasing attention as a promising avenue for addressing mood disorders. This study aimed to assess the potential effect of supplementing standard pharmacological treatment with the probiotic kefir in patients with Major Depressive Disorder (MDD).
Methods: Thirty-eight female participants diagnosed with moderate MDD by the Hamilton Rating Scale for Depression (HAM-D) were selected to receive the probiotic kefir in conjunction with antidepressant therapy for 12 weeks.
Clinical outcome of BCG treatment for patients with urothelial carcinoma of the prostatic urethra: Implications for early cystectomy.

Purposes: This study aimed to clarify the clinical outcomes of Bacillus Calmette-Guérin (BCG) treatment in patients with urothelial carcinoma (UC) of the prostatic urethra.
Methods: Between August 2003 and January 2023, 428 patients with non-muscle-invasive UC received BCG treatment (Tokyo strain, 80 mg, ≥ 5 times) in our hospital; 39 had UC of the prostatic urethra. We evaluated the cumulative incidence of intravesical recurrence, progression (muscle-invasive bladder cancer [MIBC] or metastasis), and subsequent radical cystectomy after BCG treatment in patients with UC of the prostatic urethra.

Photodynamic therapy is a highly promising method for cancer adjuvant treatment. However, the current research on the microscopic changes during the photodynamic therapy process is still quite limited, which seriously impedes the deep understanding of the procedure. For this purpose, a novel polarity-responsive probe, , with excellent mitochondrial targeting and anchoring capabilities has been rationally designed and synthesized.

Background: Breast conservation therapy for patients with DCIS includes breast conserving surgery (BCS) with post-operative radiotherapy (RT). Because RT does not impact overall survival, identifying women who do not benefit from RT would allow de-escalation of therapy. We evaluated the impact of a novel 7-gene DCIS biosignature on adjuvant radiation recommendations for patients undergoing BCS for DCIS.
