Survival outcomes comparing minimally invasive versus open cytoreductive surgery in recurrent adult-type granulosa cell tumors.

Background: Adult-type granulosa cell tumors are a rare form of ovarian cancer, 30% of which will recur. Cytoreductive surgery is often performed at the time of a first recurrence, but little is known about the impact of open versus minimally invasive surgical approaches on survival outcomes.

Objective: To examine associations between surgical approach, clinical variables, and survival outcomes among patients with adult-type granulosa cell tumors who underwent cytoreductive surgery at the time of first recurrence.

Gain-of-Function Chromatin Remodeling Activity of Oncogenic FOXL2-C134W Reprograms Glucocorticoid Receptor Occupancy to Drive Granulosa Cell Tumors.

Adult type ovarian granulosa cell tumors (AGCTs) are rare malignancies with the near universal c.C402G (p.Cys134Trp) somatic mutation in FOXL2, a Forkhead box-family transcription factor important for ovarian function.

promoter mutations and survival outcomes in adult-type granulosa cell tumors.

Objectives: To evaluate survival outcomes among patients with adult-type granulosa cell tumors who have telomerase reverse transcriptase () promoter mutations.

Methods: This is a retrospective cohort study using the MD Anderson Rare Gynecologic Malignancy Registry. Patients with adult granulosa cell tumors who underwent molecular testing for promoter and c.

Serial cytoreductive surgery and survival outcomes in recurrent adult-type ovarian granulosa cell tumors.

Background: Few studies have evaluated the role of cytoreductive surgery in patients with recurrent adult granulosa cell tumors of the ovary. Despite a multitude of treatment modalities in the recurrent setting, the optimal management strategy is not known. Cytoreductive surgery offers an attractive option for disease confined to the abdomen/pelvis.

Comparative Tumor Microenvironment Analysis of Primary and Recurrent Ovarian Granulosa Cell Tumors.

Unlabelled: Adult-type granulosa cell tumors (aGCT) are rare ovarian sex cord tumors with few effective treatments for recurrent disease. The objective of this study was to characterize the tumor microenvironment (TME) of primary and recurrent aGCTs and to identify correlates of disease recurrence. Total RNA sequencing (RNA-seq) was performed on 24 pathologically confirmed, cryopreserved aGCT samples, including 8 primary and 16 recurrent tumors.

Inflammation-induced PELP1 expression promotes tumorigenesis by activating GM-CSF paracrine secretion in the tumor microenvironment.

The inflammatory tumor microenvironment has been implicated as a major player fueling tumor progression and an enabling characteristic of cancer, proline, glutamic acid, and leucine-rich protein 1 (PELP1) is a novel nuclear receptor coregulator that signals across diverse signaling networks, and its expression is altered in several cancers. However, investigations to find the role of PELP1 in inflammation-driven oncogenesis are limited. Molecular studies here, utilizing macrophage cell lines and animal models upon stimulation with lipopolysaccharide (LPS) or necrotic cells, showed that PELP1 is an inflammation-inducible gene.

Clinical Evaluation of P21 Activated Kinase 1 (PAK1) Activation in Gliomas and Its Effect on Cell Proliferation.

Glioblastomas are the primary malignant tumors of brain tissues with poor prognosis and highly invasive phenotypes. Till now Ki-67 LI has emerged as a well-studied proliferation marker that aids in tumor grading, but labeling index alone cannot predict overall survival in gliomas. P21 activated kinase 1 (PAK1) - a serine/threonine kinase has been shown to function as downstream nodule for various oncogenic signaling pathways that promote neoplastic changes.

Clinical Evaluation of Proline, Glutamic acid, and Leucine-Rich Protein 1 Expression in Astrocytomas and Correlations with the Proliferation Marker Ki-67.

Malignant astrocytomas presenting in humans of any age group are a challenge to diagnose and treat. Hence, there is a quest for new markers to ascertain their grades and predict disease outcomes. Proline, glutamic acid, and leucine-rich protein 1 (PELP1), a nuclear receptor co-regulator, is an oncogene found in various cancers.

Facile synthesis and nanoscale features of a nanostructured nordihydroguaiaretic acid analog for therapeutic applications.

Background: Nordihydroguaiaretic acid (NDGA) is a plant lignan obtained from creosote bush, known to possess anti-oxidant, anti-cancer and anti-viral activities and is being used in traditional medicine. However, toxicity studies indicated liver and kidney damage despite its immense medicinal properties. There has been a recent increase of curiosity in the chemical synthesis of NDGA derivatives for therapeutic applications.
