Objective: The aim was to evaluate relationship between apparent diffusion coefficient (ADC) values with pathologic prognostic factors in breast carcinoma (BC).
Materials And Methods: 83 patients were enrolled in this study. Prognostic factors included age, tumor size, expression of estrogen receptor (ER) and progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), nuclear grade (NG), lymph node involvement and histologic type. The relationship between ADC and prognostic factors was determined using Independent sample t-test, ANOVA, Pearson correlation and relative operating characteristics (ROC) analysis.
Results: There was no significant difference between ADC and prognostic factors, including age, tumor size, ER, HER2 and histologic type. The PR-positive tumors (p=0.03) and axillary lymph node involvement (p=0.000) showed a significant association with lower ADC values. The ADC values were significantly lower in high-grade tumors than low-grade tumors (p=0.000). ROC analysis showed an optimal ADC threshold of 0.66 (×10-3 mm2/s) for differentiating low-grade tumors from high-grade tumors (sensitivity, 85.5%; specificity, 81%; area under curve, 0.90).
Conclusion: The lower ADC values of BC were significantly associated with positive expression of PR, LN positivity and high-grade tumor. Especially, ADC values were valuable in predicting NG subgroups.
Aim: The prognosis of masked hypertension is controversial. The aims of this meta-analysis were to determine the global prevalence of masked hypertension and to better understand its association with the risk of cardiorenal comorbidities and all-cause mortality.
Methods: We searched the PubMed, Embase (OVID), The Cochrane Library, WanFang Data, and CNKI databases for relevant studies published from inception until January 15, 2024.
Background: Tumor recurrence or metastasis after surgery is a significant factor influencing bladder cancer (BC) prognosis. Novel molecular biomarkers are necessary to determine each patient's specific outcome because current biomarkers have limited power for predicting prognosis. The proto-oncogene MET encodes c-MET, a tyrosine kinase receptor.
Background: This study compared short- and mid-term outcomes of hemihepatectomy (HH) and pancreatoduodenectomy (PD) in patients with extrahepatic cholangiocarcinoma, focusing on surgical outcomes, body composition, and nutritional status.
Method: A retrospective review was conducted to assess short-term outcomes, including operative time, blood loss, complications, and mortality. Body composition and nutritional parameters were analyzed preoperatively and 1 year postoperatively.

A poorer prognosis is thought to be associated with "double expressor lymphomas," which are a subtype of diffuse large B cell lymphomas (DLBCL) that co-express MYC and BCL2. While the role of ubiquitin-specific peptidase 37 (USP37) in lung cancer, where it mediates the deubiquitination and stabilization of c-myc, has been well-documented, its involvement in DLBCL remains unexplored. The use of RT-PCR, immunohistochemistry, or WB test allowed for the detection of elevated USP37 in DLBCL tissues and cells.
Background: Gastric cancer (GC) shows limited response to immune checkpoint inhibitors due to its complex tumor immune microenvironment (TIME). This study explores the functions of various immune cells in the complex TIME in GC.
Methods: We assessed CD8 + T-cell infiltration of GC tissues by immunohistochemistry, and performed single-cell RNA sequencing (scRNA-seq) of tumor and normal tissues from 34 patients with GC.
