Differential diagnosis of non-molar gestational trophoblastic neoplasia with ectopic pregnancy by clinical-pathological features.

Purpose: This study was presented to investigate the clinical-pathological characteristics of gestational trophoblastic neoplasia (GTN) following non-molar pregnancy and differentiated with ectopic pregnancy (EP).

Methods: The clinical data of 83 patients who were admitted for suspected GTN after non-molar pregnancy at the Women's Hospital School of Medicine Zhejiang University from January 2015 to September 2022 were selected for analysis.

Results: In total, 41 cases were confirmed non-molar GTN, including 31 choriocarcinoma, 9 PSTT (placental site trophoblastic tumor), and 1 ETT (epithelioid trophoblastic tumor), while 42 cases were confirmed EP.

Generation of a Specific Fluorescence In Situ Hybridization Test for the Detection of Ovarian Carcinoma Cells.

Examinations of ovarian cancer cells require the ability to identify tumor cells. Array-based comparative genome hybridization (aCGH) on 30 ovarian carcinomas (OC) identified three genomic loci (8q24.23; 17p12; 18q22.

STAT3 mediates ECM stiffness-dependent progression in ovarian cancer.

The treatment of ovarian cancer remains a medical challenge and its malignant progression is connected with obvious changes in both tissue and cell stiffness. However, the accurate mechanical-responsive molecules and mechanism remains unclear in ovarian cancer. Based on our previous results combined with the crucial regulatory role of STAT3 in the malignant progression of various cancer types, we want to investigate the relationship between STAT3 and matrix stiffness in ovarian cancer and further explore the potential mechanisms.

Assessing the Phenotype of a Homologous Recombination Deficiency Using High Resolution Array-Based Comparative Genome Hybridization in Ovarian Cancer.

Ovarian cancer (OC) cells with homologous recombination deficiency (HRD) accumulate genomic scars (LST, TAI, and LOH) over a value of 42 in sum. PARP inhibitors can treat OC with HRD. The detection of HRD can be done directly by imaging these genomic scars, or indirectly by detecting mutations in the genes involved in HR.

Case report: Squamous cell carcinoma and spindle cell sarcoma (SCS) arising in a mature cystic teratoma of the ovary.

Objective: Malignant transformation of mature ovarian teratoma is a rare phenomenon, mainly occurring in postmenopausal period. Squamous cell carcinoma accounts for 80% of all malignant transformations. Sarcoma transformation is much less common and tends to imply a poorer prognosis and aggressiveness.

Gastric-type Mucinous Carcinoma with an Abnormal Increase of CA199: A Case Report and Literature Review.

Objective: Gastric-type mucinous carcinoma (GAS), as a rare subtype of mucinous adenocarcinoma, accounts for approximately 1%-3% of cervical adenocarcinoma. It was considered as a new type of cervical mucinous adenocarcinoma by the World Health Organization (WHO) in 2014. GAS represents more aggressive disease than does usual type endocervical adenocarcinoma (UEA).

Epithelioid trophoblastic tumor that requires fertility preservation: A case report and review of literature.

Objective: Epithelioid trophoblastic tumor (ETT) is very rare and few cases have been published in the English literature. Hysterectomy is the recommended treatment, due to the high rate of recurrence and mortality. The objective of this article is to present a rare case of ETT with fertility-preserving treatment and review published similar cases.

Notch1 Affects Chemo-resistance Through Regulating Epithelial-Mesenchymal Transition (EMT) in Epithelial Ovarian cancer cells.

: Epithelial ovarian cancer (EOC) is the most lethal gynecological malignancy, chemo-resistance is the main cause for treatment failure. Our previous studies have found that SKOV3 could promote immune escape and tumor progression via Notch1 pathway. Therefore, Notch1 is suspected to be involved in chemo-resistance.

Lamivudine vs placebo or no treatment in preventing the transmission of hepatitis B virus during pregnancy: a systematic review and meta-analysis.

Background: Hepatitis B virus (HBV) infection is a severe health problem, especially in developing countries. Almost 45% of the population lives in highly endemic areas, where the most common form of transmission is mother to child transmission (MTCT). Administration of antiviral therapy has been established.

Synchronous occurrence of benign mesothelioma and adenomatoid tumor of uterus: A case report and review of literature.

Introduction: Synchronous occurrence of benign cystic mesothelioma and adenomatoid tumor of uterus (UAT) are very rare and few cases have been published in the English literature. They are easily misdiagnosed as malignant by clinicians, due to the lack of reports.

Patient Concerns: A case of benign mesothelial combined with uterus adenomatoid tumor (UAT) in a 48-year-old Chinese woman was reported.

Clinical Predictors of Recurrence and Prognostic Value of Lymph Node Involvement in the Serous Borderline Ovarian Tumor.

Aim: This study was aimed to evaluate the risk factors of recurrence and the value of nodal involvement in patients with serous borderline ovarian tumors (SBOT).

Methods: Two hundred twenty-five patients who underwent surgery and were diagnosed with SBOT were retrospectively studied. Univariate and multivariate analyses were used to assess the risk factors for recurrence.

Inhibition of Notch 1 receptor influenced the differentiation of Lin-CD45RA-dendritic cell precursors within ovarian carcinoma microenvironment.

Background: Previous evidence suggested that the differentiation of Lin-CD45RA-DC precursors were prior to plasmcytoid dendritic cells (pDCs) than myeloid dendritic cells (mDCs) within ovarian cancer microenvironment. However, the mechanism is still unclear. Therefore, we investigated the function of Notch 1 signal pathway in the differentiation of Lin-CD45RA-DC precursors.

Long-term outcome of patients with persistent low-level elevation of human chorionic gonadotrophin.

Aim: The aim of this study was to investigate a series of patients with sustained low-level elevated human chorionic gonadotrophin (hCG) and explore the management of these patients.

Methods: A total of 47 patients with persistent low levels of hCG were selected for analysis between January 2002 and January 2014 at the Women's Hospital of Zhejiang University, Hangzhou, China. Data were retrospectively reviewed for patient characteristics, therapeutic strategies, and follow-ups.
