Objective: To investigate the correlation between age and Gleason score (GS) in patients with prostate adenocarcinoma.
Methods: This study included 674 patients with pathologically confirmed prostate adenocarcinoma. We determined the GS, primary grade, and secondary grade of the cases, and compared them among different age groups.
Results: The mean age of the patients was (70.22 ± 8.26) yr, ranging from 25 to 96 years, (69.06 ± 8.35) yr in those with GS 6, (70.55 ± 8.16) yr in GS 7, (70.99 ± 6.54) yr in GS 8, (71.56 ± 9.18) yr in GS 9, and (72.79 ± 11.36) in GS 10. The mean GS, primary grade, and secondary grade were 7.08 ± 1.09, 3.54 ± 0.72, and 3.53 ± 0.66, respectively, and the mean GSs in the < 60 yr, 60-69 yr, 70-79 yr, and ≥ 80 yr groups were 6.86 ± 1.10, 6.99 ± 1.10, 7.08 ± 1.04, and 7.38 ± 1.23, respectively. Those with GS 6, 7, and ≥ 8 accounted for 37.7%, 34.3%, and 28.0%, respectively. The patients aged < 60, 60-69, 70-79, and ≥ 80 years constituted 10.5% (71/674), 30.6% (206/674), 47.6% (321/674), and 11.3% (76/674), respectively. The age of the patients was significantly correlated with GS (r2 = 0.013, P = 0.003) and the primary grade (r2 = 0.014, P = 0.002), but not the secondary grade (r2 = 0.005, P = 0.055).
Conclusion: Of the prostate adenocarcinoma patients, those aged ≥ 70 years form a larger proportion, and those with GS ≥ 7 comprise a higher percentage. The age of the patient is correlated with Gleason score but has a limited value in its prediction.

This study evaluates the feasibility of using Haralick texture analysis on low-field, T2-weighted MRI images for detecting prostate cancer, extending current research from high-field MRI to the more accessible and cost-effective low-field MRI. A total of twenty-one patients with biopsy-proven prostate cancer (Gleason score 4+3 or higher) were included. Before transperineal biopsy guided by low-field (58-74mT) MRI, a radiologist annotated suspicious regions of interest (ROIs) on high-field (3T) MRI.

Low-grade myofibroblastic sarcoma is an uncommon malignancy that can be difficult to identify and for which there is no unified treatment protocol. We report herein a case of an 81-year-old male who presented with a giant irregular breast mass and was diagnosed with low-grade myofibroblastic sarcoma. In this study we summarise the clinicopathological features of 13 reported cases of myofibroblastic sarcoma arising in the breast, present the diagnostic process and treatment procedure of our case, and discuss the differential diagnosis from other similar diseases, to provide constructive information and promote deep understanding of myofibroblastic sarcoma in the future.

Background: Exploring the potential of as a diagnostic biomarker in prostate cancer.
Methods: Expression of the lncRNA was analyzed between normal and tumor samples in the GDC TCGA PRAD (Genomic Data Commons: The Cancer Genome Atlas Prostate Adenocarcinoma Collection) dataset. Disease progression-related clinicopathological parameters such as serum PSA level (ng/ml) and Gleason score were associated with the expression of using the same GDC TCGA PRAD dataset.

Currently, the World Health Organization (WHO) grade of meningiomas is determined based on the biopsy results. Therefore, accurate non-invasive preoperative grading could significantly improve treatment planning and patient outcomes. Considering recent advances in machine learning (ML) and deep learning (DL), this meta-analysis aimed to evaluate the performance of these models in predicting the WHO meningioma grade using imaging data.

Objective: In advanced ovarian cancer, the majority of patients receive anti-angiogenic treatment with bevacizumab. However, its use is often associated with severe side effects, and not all patients benefit from the therapy. Currently, there are no reliable biomarkers to predict response to treatment.
