Effect of External Beam Radiation Therapy and Brachytherapy on Circulating Myeloid-Derived Suppressor Cell Populations in Patients Treated Definitively for Cervical Cancer.

Purpose: The immunosuppressive function of myeloid-derived suppressor cells (MDSCs) has been implicated in the regulation of immune responses against cancer and is associated with poor prognosis. Radiation treatment is known to alter immune cell populations within the tumor; however, whether this results in the recruitment of immunosuppressive MDSC populations is not well understood. Here we evaluate the response of circulating MDSC populations in patients treated per standard-of-care cisplatin chemoradiation therapy (CRT) for locally invasive cervical cancer.

Associations of cytomegalovirus infection with cancer-related cognitive impairment and peripheral neuropathy in ovarian cancer survivors.

Objective: To assess the associations between active CMV infection and patient-reported symptoms of cancer-related cognitive impairment (CRCI) and peripheral neuropathy in ovarian cancer survivors.

Methods: We conducted a cross-sectional study among individuals with a diagnosis of ovarian cancer, primary peritoneal cancer, or fallopian tube cancer from academic and community cancer clinics at any time point after completion of front-line chemotherapy. Participants completed a one-time survey and provided a blood sample.

Increased expression of collagen prolyl hydroxylases in ovarian cancer is associated with cancer growth and metastasis.

Tumor hypoxia induces collagen deposition and extensive extracellular matrix remodeling, significantly enhancing the processes of invasion and metastasis. Collagen prolyl-4-hydroxylases (P4HA) play a critical role in collagen post-translational modification. The primary objective of this study is to comprehensively assess the role of P4HA in promoting ovarian cancer growth and facilitating metastasis.

Intronic Germline Variants in Patients With Sertoli-Leydig Cell Tumor.

Germline pathogenic loss-of-function (pLOF) variants in are associated with a predisposition for a variety of solid neoplasms, including pleuropulmonary blastoma and Sertoli-Leydig cell tumor (SLCT). The most common pLOF variants include small insertions or deletions leading to frameshifts, and base substitutions leading to nonsense codons or altered splice sites. Larger deletions and pathogenic missense variants occur less frequently.

Biological Insights into Chemotherapy Resistance in Ovarian Cancer.

The majority of patients with high-grade serous ovarian cancer (HGSOC) initially respond to chemotherapy; however, most will develop chemotherapy resistance. Gene signatures may change with the development of chemotherapy resistance in this population, which is important as it may lead to tailored therapies. The objective of this study was to compare tumor gene expression profiles in patients before and after treatment with neoadjuvant chemotherapy (NACT).

A patient-centered mobile health application to motivate use of genetic counseling among women with ovarian cancer: A pilot randomized controlled trial.

Objective: Despite current guidelines recommending women with ovarian cancer receive genetic risk evaluation by a genetic counselor, utilization has historically been low. We sought to assess the feasibility and effectiveness of a week-long mobile Application for Genetic Information on Cancer (mAGIC) intervention aimed to persuade women with ovarian cancer to pursue genetic counseling.

Methods: The mobile application intervention was based on the Fogg Behavior Model, and consisted of three parts: (1) identifying barriers, (2) developing motivators, and (3) providing triggers to action.

RNA Sequencing of Carboplatin- and Paclitaxel-Resistant Endometrial Cancer Cells Reveals New Stratification Markers and Molecular Targets for Cancer Treatment.

Despite advances in surgical technique and adjuvant treatment, endometrial cancer has recently seen an increase in incidence and mortality in the USA. The majority of endometrial cancers can be cured by surgery alone or in combination with adjuvant chemo- or radiotherapy; however, a subset of patients experience recurrence for reasons that remain unclear. Recurrence is associated with chemoresistance to carboplatin and paclitaxel and consequentially, high mortality.

Objective: To report clinical and pathologic relationships with disease spread in endometrial cancer patients.

Methods: Surgical candidates with uterine cancer (adenocarcinoma or carcinosarcoma) who were eligible to participate in a surgical pathological study to create a clinically annotated tissue biorepository to support translational and clinical research studies. All patients were to undergo a hysterectomy, bilateral salpingo-oophorectomy, and bilateral pelvic and para-aortic lymphadenectomy.

Ectodomain shedding of the cell adhesion molecule Nectin-4 in ovarian cancer is mediated by ADAM10 and ADAM17.

We previously showed that the cell adhesion molecule Nectin-4 is overexpressed in ovarian cancer tumors, and its cleaved extracellular domain can be detected in the serum of ovarian cancer patients. The ADAM (isintegrin nd etalloproteinase) proteases are involved in ectodomain cleavage of transmembrane proteins, and ADAM17 is known to cleave Nectin-4 in breast cancer. However, the mechanism of Nectin-4 cleavage in ovarian cancer has not yet been determined.
