Inspect quantitative signals in placental histopathology: Computer-assisted multiple functional tissues identification through multi-model fusion and distillation framework.

Pathological analysis of placenta is currently a valuable tool for gaining insights into pregnancy outcomes. In placental histopathology, multiple functional tissues can be inspected as potential signals reflecting the transfer functionality between fetal and maternal circulations. However, the identification of multiple functional tissues is challenging due to (1) severe heterogeneity in texture, size and shape, (2) distribution across different scales and (3) the need for comprehensive assessment at the whole slide image (WSI) level.

Morphological Diversity of the Endometrium in Choriocarcinoma Specimens and its Role in Differential Diagnosis.

The morphological characteristics of the endometrium in patients with choriocarcinoma have not been well described. We described the endometrial morphology patterns in 46 choriocarcinomas and analyzed their relationship with the clinicopathological characteristics of these patients. Forty-six patients diagnosed with choriocarcinoma that had sufficient endometrial tissues for histopathological diagnosis were selected.

HPV genotyping of cervical histologic specimens of 61, 422 patients from the largest women hospital in China.

Objectives: We investigated HPV genotypes in a large cohort of patients with definitive cervical histologic diagnosis.

Methods: HPV testing was performed by real-time PCR assay, including 18 high-risk HPV (hrHPV) and 3 low-risk HPV (lrHPV). Totally 61,422 patients with documented HPV genotyping results within 6 months before cervical histologic diagnoses were included.

The clinical utility of extended high-risk HPV genotyping in risk-stratifying women with L-SIL cytology: A retrospective study of 8726 cases.

Background: The value of extended high-risk human papillomavirus (hrHPV) genotyping for cervical cancer screening in women with low-grade squamous intraepithelial lesion (L-SIL) cytology has been recognized, but few studies have investigated this.

Methods: Women with L-SIL Papanicolaou results who underwent human papillomavirus (HPV) genotyping between October 2017 and October 2021 at the Obstetrics and Gynecology Hospital of Fudan University were identified. Their HPV results were correlated with immediate histopathologic follow-up findings.

Precise Measurement of the Thickness of Vaginal Intraepithelial Neoplasia.

Objectives: Although carbon dioxide laser vaporization is frequently used for treating vaginal intraepithelial neoplasia (VaIN), the optimal depth of epithelial destruction with laser vaporization requires elucidation. We aimed to evaluate VaIN depth and better illustrate epithelial destruction during laser vaporization.

Materials And Methods: We included 246 women diagnosed with VaIN (low-grade VaIN [VaIN 1], 123 women; high-grade VaIN [VaIN 2/3], 123 women) using colposcopy-directed biopsy at our hospital from January 1, 2019, to April 30, 2020.

CCL20 triggered by chemotherapy hinders the therapeutic efficacy of breast cancer.

Chemotherapeutic resistance in triple-negative breast cancer (TNBC) has brought great challenges to the improvement of patient survival. The mechanisms of taxane chemoresistance in TNBC have not been well investigated. Our results illustrated C-C motif chemokine ligand 20 (CCL20) was significantly elevated during taxane-containing chemotherapy in breast cancer patients with nonpathologic complete response.

Heterogeneity of PD-L1 expression in primary tumors and paired lymph node metastases of triple negative breast cancer.

Background: Programmed cell death ligand 1 (PD-L1) is a potential predictive biomarker of the response to anti-PD-L1/anti- programmed cell death 1 (PD-1) therapy in multiple cancers, including triple negative breast cancer(TNBC). The purpose of this study was to investigate whether PD-L1 expression is homogenous in primary tumors(PTs) and synchronous axillary lymph node metastases(LNMs) of TNBC.

Methods: PD-L1 expression was immunohistochemically evaluated in 101 TNBC patients' PTs and paired LNMs.

Low frequency of BRAF and KRAS mutations in Chinese patients with low-grade serous carcinoma of the ovary.

Background: Mounting evidence has shown that KRAS and BRAF are somatic mutations associated with low grade serous carcinoma (LGSC) of the ovary. However, the frequency of KRAS or BRAF mutation was variable in literatures, with a frequency of 16-54% for KRAS mutation and 2-33% for BRAF mutation. Meanwhile, the prognostic significance of KRAS or BRAF mutation remains controversial.

HDAC5, a potential therapeutic target and prognostic biomarker, promotes proliferation, invasion and migration in human breast cancer.

Purpose: Histone deacetylase 5 (HDAC5) is an important protein in neural and cardiac diseases and a potential drug target. However, little is known regarding the specific role of HDAC5 in breast cancer (BC). We aimed to evaluate HDAC5 expression in human breast tumors and to determine the effects of the inhibition of HDAC5 expression in BC cells.
