Background: "Financial Toxicity" (FT) is the financial burden imposed on patients due to disease and its treatment. Approximately 50% of gynecologic oncology patients experience FT. This study describes the implementation and outcomes of a novel financial navigation program (FNP) in gynecologic oncology., Methods: Patients presenting for initial consultation with a gynecologic oncologist from July 2022 to September 2023 were included. A FNP was launched inclusive of hiring a financial navigator (FN) in July 2022, and implementing FT screening in October 2022. We prospectively captured patient referrals to the FN, collecting clinical, demographic, financial and social needs information, along with FN interventions and institutional support service referrals. Referrals to the FN and support services were quantified before and after screening implementation., Results: There were 1029 patients with 21.6% seen before and 78.4% after screening initiation. Median age was 58 (IQR 46-68). The majority were non-Hispanic white (60%) with private insurance (61%). A total of 10.5% patients were referred to the FN. Transportation (32%), financial assistance (20.5%) and emotional support (15.4%) were the most common needs identified. A higher proportion of patients referred to the FN identified as Black, had government-funded insurance or diagnoses of uterine or cervical cancers (p < 0.05). Post-screening referrals to FN increased (5% vs. 12.9%, p < 0.001), while referrals to other support services decreased (9.5% vs. 2.9%, p < 0.001)., Conclusions: Implementation of the FNP was feasible, though presence of both a FN and FT screening maximized its effectiveness. Further investigation is needed to understand screening barriers and evaluate longer-term impact., Competing Interests: Declaration of competing interest There are no conflicts of interest to disclose., (Copyright © 2024.

Background: Ovarian cancer is the leading cause of gynecologic cancer death in the United States despite effective first-line systemic chemotherapy. Cancer stem cells (CSCs) retain the ability to self-renew and proliferate and may be a means of harboring disease that evades standard treatment strategies. We previously performed a high-throughput screen to assess differential protein expression in ovarian CSCs compared to non-CSCs and observed that Thy-1 was more highly expressed in CSCs. Our primary aim was to validate Thy-1 (CD90) as a cancer stem cell (CSC) marker in epithelial ovarian cancer (EOC), correlate with clinical outcomes, and assess as a potential therapeutic target., Results: Kaplan Meier (KM) Plotter data were correlated with survival outcomes. Quantitative real-time PCR, flow cytometry, and immunoblots assessed RNA and protein expression. Limiting dilution assays assessed self-renewal capacity and proliferation assays assessed proliferative capacity. RNA in-situ hybridization was performed on patient specimens to assess feasibility. Thy-1 (CD90) is more highly expressed in ovarian CSCs than non-CSCs, in EOC compared to benign ovarian epithelium (P < 0.001), and is highest in serous EOC (P < 0.05). Serous ovarian cancers with high Thy-1 expression have poorer outcomes (median PFS 15.8 vs. 18.3 months, P = 0 < 0.001; median OS 40.1 v. 45.8 months, P = 0.036). Endometrioid ovarian cancers with high Thy-1 have poorer PFS, but no difference in OS (upper quartile PFS 34 v. 11 months, P = 0.013; quartile OS not reached, P = 0.69). In vitro, Thy-1 expression is higher in CSCs versus non-CSCs. EOC cells with high Thy-1 expression demonstrate increased proliferation and self-renewal. Thy-1 knockdown in EOC cells decreases proliferative capacity and self-renewal capacity, and knockdown is associated with decreased expression of stem cell transcription factors NANOG and SOX2. RNA in situ hybridization is feasible in ovarian cancer tissue specimens., Conclusions: Thy-1 is a marker of ovarian CSCs. Increased expression of Thy-1 in EOC predicts poor prognosis and is associated with increased proliferative and self-renewal capacity. Thy-1 knockdown decreases proliferative and self-renewal capacity, and represents a potential therapeutic target.

► Skin metastasis of ovarian cancer is rare, often nodular in appearance, and conveys a poor prognosis. ► This patient developed an unusual maculo-papular rash which was biopsy-proven to be metastatic endometrioid adenocarcinoma. ► Pruritic symptoms from skin metastases should be palliated; SSRIs, local radiation, and topical creams all may play a role.

Idiopathic pulmonary arterial hypertension (PAH) is a life-threatening condition characterized by pulmonary arteriolar remodeling. This investigation aimed to identify genes involved specifically in the pathogenesis of PAH and not other forms of pulmonary hypertension (PH). Using genomewide microarray analysis, we generated the largest data set to date of RNA expression profiles from lung tissue specimens from 1) 18 PAH subjects and 2) 8 subjects with PH secondary to idiopathic pulmonary fibrosis (IPF) and 3) 13 normal subjects. A molecular signature of 4,734 genes discriminated among these three cohorts. We identified significant novel biological changes that were likely to contribute to the pathogenesis of PAH, including regulation of actin-based motility, protein ubiquitination, and cAMP, transforming growth factor-beta, MAPK, estrogen receptor, nitric oxide, and PDGF signaling. Bone morphogenic protein receptor type II expression was downregulated, even in subjects without a mutation in this gene. Women with PAH had higher expression levels of estrogen receptor 1 than normal women. Real-time quantitative PCR confirmed differential expression of the following genes in PAH relative to both normal controls and PH secondary to IPF: a disintegrin-like and metalloprotease with thrombospondin type 1 motif 9, cell adhesion molecule with homology to L1CAM, cytochrome b(558) and beta-polypeptide, coagulation factor II receptor-like 3, A-myb myeloblastosis viral oncogene homolog 1, nuclear receptor coactivator 2, purinergic receptor P2Y, platelet factor 4, phospholamban, and tropomodulin 3. This study shows that PAH and PH secondary to IPF are characterized by distinct gene expression signatures, implying distinct pathophysiological mechanisms.
