Purpose: We performed a comparative analysis of the plasma levels of antithrombin (AT) III, plasminogen, fibrinogen, and D-dimer among patients with and without clinically localized prostate cancer to investigate the clinical significance of the coagulation profile in prostate cancer.
Materials And Methods: A prospective study was performed in which plasma levels of AT III, plasminogen, fibrinogen, and D-dimer were assessed in patients before they underwent prostate biopsy. According to the results of the biopsy, the patients were categorized into the cancer group or the control group. Levels of the four coagulation factors were then compared between the cancer and control groups. Also, levels of the four coagulation factors were correlated with tumor stage and grade in the cancer group.
Results: The cancer group had significantly lower levels of AT III activity and higher plasma D-dimer levels than did the control group (p=0.007 and p=0.018, respectively). Within the cancer group, no significant differences were observed in the levels of AT III, plasminogen, fibrinogen, or D-dimer between those with a pathological Gleason score of >/=7 and otherwise. Regarding pathologic stage of prostate cancer, the subjects with organ-confined disease and those with extraprostatic extension of a tumor demonstrated no significant differences in the preoperative levels of the four coagulation factors analyzed.
Conclusions: Our results suggest that plasma levels of AT III and D-dimer are altered in patients with prostate cancer. Further study is needed to elucidate the underlying mechanism and clinical significances of such a phenomenon among patients with clinically localized prostate cancer.

Although restrictive eligibility criteria contribute to this issue, the role of selection bias related to prognostic risk remains unclear. In this study, we developed TrialTranslator, a framework designed to systematically evaluate the generalizability of RCTs for oncology therapies.

Alexithymia, a cognitive and emotional deficit characterized by difficulty in expressing emotions and identifying feelings, poses significant challenges in healthcare settings. Developing a reliable and valid tool to measure alexithymia in post-prostatectomy patients would not only aid healthcare professionals in identifying at-risk individuals but also facilitate early intervention and targeted support. This study aimed to translate the Brief Form of the Normative Male Alexithymia Scale (NMAS-BF) into Simplified Chinese, evaluate the reliability and validity of the Chinese version, and explore its influencing factors.

Background: Multiparametric MRI (Mp-MRI) is a key tool to screen for Prostate Cancer (Pca) and Clinically Significant Prostate Cancer (CsPca). It primarily includes T2-Weighted imaging (T2w), diffusion-weighted imaging (DWI), and Dynamic Contrast-Enhanced imaging (DCE). Despite its improvements in CsPca screening, concerns about the cost-effectiveness of DCE persist due to its associated side effects, increased cost, longer acquisition time, and limitations in patients with poor kidney function.

Rationale And Objectives: To develop an automatic deep-radiomics framework that diagnoses and stratifies prostate cancer in patients with prostate-specific antigen (PSA) levels between 4 and 10 ng/mL.
Materials And Methods: A total of 1124 patients with histological results and PSA levels between 4 and 10 ng/mL were enrolled from one public dataset and two local institutions. An nnUNet was trained for prostate masks, and a feature extraction module identified suspicious lesion masks.
