Patient Preferences and Knowledge Regarding Hysterectomy: A Study from the Fellows' Pelvic Research Network (FPRN)®.

OBJECTIVE: The purpose of this study was to describe preference for and knowledge of hysterectomy routes in women presenting to urogynecology/gynecology clinics throughout the United States and to determine association with health literacy. Our primary aim was preference for hysterectomy route, and secondary aims were knowledge of basic pelvic structures and function, knowledge of various hysterectomy routes, and baseline health literacy level. METHODS: This multicenter, cross-sectional study was conducted through the Fellows' Pelvic Research Network. Patients' preference and knowledge for hysterectomy routes were assessed at initial presentation to the urogynecology/gynecology clinic with an anonymous, voluntary, self-administered questionnaire along with a validated health literacy test (Medical Term Recognition Test). RESULTS: Two hundred four women participated. Forty-five percent of patients were unsure which hysterectomy modality they would choose. Of patients who selected a preferred modality, 50% selected laparoscopic and 33% selected vaginal. Patients indicated that safety was considered highest priority when selecting route. The mean score for "knowledge about gynecology/hysterectomy" was 68%, with the high literacy group scoring higher compared with the low health literacy group (70% vs 60.1%, P = 0.01). More than 50% of patients incorrectly answered knowledge questions related to vaginal hysterectomy. Majority of the respondents had high health literacy (79.4%). CONCLUSIONS: Patients prefer laparoscopic hysterectomy approach, although have limited understanding of vaginal hysterectomy. Higher health literacy levels are associated with increased knowledge of gynecology and hysterectomy routes, but were not found to influence patient preference for hysterectomy route. Overall, patients have limited knowledge of vaginal hysterectomy.

Identification of a serum-induced transcriptional signature associated with metastatic cervical cancer.

OBJECTIVE: Tumor cells that escape local tissue control can convert inflammatory cells from tumor suppressors to tumor promoters. Moreover, soluble immune-modulating factors secreted from the tumor environment can be difficult to identify in patient serum due to their low abundance. We used an alternative strategy to infer a metastatic signature induced by sera of cervical cancer patients. METHODS: Sera from patients with local and metastatic cervical cancer were used to induce a disease-specific transcriptional signature in cultured, healthy peripheral blood mononuclear cells (PBMCs). An empirical Bayesian method, EBarrays, was used to identify differentially expressed (DE) genes with a target false discovery rate of <5%. Ingenuity Pathway Analysis (IPA) software was used to detect the top molecular and cellular functions associated with the DE genes. IPA and in silco analysis was used to pinpoint candidate upstream regulators, including cancer-related microRNAs (miRNAs). RESULTS: We identified enriched pathways in the metastatic cervical group related to immune surveillance functions, such as downregulation of engulfment, accumulation, and phagocytosis of hematopoietic cells. The predicted top upstream genes were IL-10 and immunoglobulins. In silco analysis identified miRNAs predicted to drive the transcriptional signature. Two of the 4 miRNAs (miR-23a-3p and miR-944) were validated in a cohort of women with local and metastatic cervical cancer. CONCLUSIONS: This study supports the use of a cell-based assay that uses PBMC "reporters" to predict biologically relevant factors in patient serum. Further, disease-specific transcriptional signatures induced by patient sera have the potential to differentiate patients with local versus metastatic disease.
