Abstract
INTRODUCTION During the past decade, the theory that high-grade extrauterine pelvic tumors originate from the fallopian tube has been strongly suggested. Our study aims to illuminate the possible role of tubal cytology as an accessory identification tool for gynecologic extrauterine malignancies, allowing in the long term the implementation of population-level cytologic tube evaluation during all benign gynecologic surgeries that do not result in salpingectomy. MATERIALS AND METHODS We ex vivo collect salpingeal epithelial cells from the fibria directly from fresh fallopian tube specimens from women undergoing salpingectomy for any indication. The cytomorphologic characteristics of the salpingeal cells are subsequently evaluated and categorized into malignant and non-malignant. Finally, the ipsilateral adnexa are examined with the SEE-FIM (Sectioning and Extensively Examining the FIMbriated End) protocol and the pathology reports are corelated with the cytologic findings. Our research protocol is ongoing and is designed to include a total of 300 patients in order to confirm the sensitivity and specificity of salpingeal cytology as a method in the early diagnosis of extrauterine gynecologic malignancies. RESULTS So far, we have obtained 343 salpingeal brushings from a total of 214 patients. The sensitivity of cytology regarding distinguishing malignant from non-malignant tumors is 69.64% (95% CI: 55.90%-81.22%), and its specificity 75.96% (95% CI: 70.59%-80.79%). Cytology's positive predictive value (PPV) is 16.33% (95% CI: 12.57%-20.67%), while the negative predictive value (NPP) reached 92.77% (95% CI: 89.56%-95.04%). In general, the diagnostic accuracy of the cytologic evaluation reaches 74.93% (95% CI: 66.99%-79.43%). CONCLUSIONS Salpingeal cytomorphologic evaluation appears to be a promising method for early detection of adnexal cancer.

Abstract
INTRODUCTION The aim of the study was to analyze the published evidence for the use of fallopian tube brush cytology for the early detection of extrauterine serous gynecological cancer. METHODS We systematically searched the literature and, additionally, cross-checked on the bibliographies of selected articles. The inclusion criteria involved studies assessing the utility of fallopian tube brush cytology and its applications in the diagnosis, screening, or follow-up of extrauterine serous gynecological cancer. RESULTS The search strategy resulted in 21 abstracts or full-text articles, 5 of which met the inclusion criteria. The year of publication ranged from 2016 to 2022, and a total of 193 fallopian tube samples were investigated. Cytobrush, Tubebrush©, and Cytuity™ were used to obtain salpingeal samples for liquid-based cytology evaluation. CONCLUSIONS Our findings indicate that, at present, there is a lack of satisfying evidence-based data in the literature which would support the implementation of fallopian tube brush cytology as an adjunctive tool for early detection of extrauterine serous gynecological cancer. Thus, we believe that there is need for well-designed clinical studies to assess the effectiveness and diagnostic accuracy of the method as well as to validate the cytological criteria for the diagnosis and prediction of gynecological malignancies.

CytoSaLPs score: a promising new tool for the detection and screening of extrauterine high grade serous carcinoma. BMC Cancer 2023; 23:157. [PMID: 36797677 PMCID: PMC9936677 DOI: 10.1186/s12885-023-10607-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2022] [Accepted: 02/03/2023] [Indexed: 02/18/2023] Open
Abstract
BACKGROUND A recent theory supports that high-grade serous epithelial ovarian cancer derives from the fimbrial end of the fallopian tube and during the last decade, a few studies have examined the fallopian tube cytology. Our study aims to determine the cytomorphological characteristics of both benign and non-benign salpingeal samples, in order to establish fallopian cytology as a valuable diagnostic test for women with high risk for development of ovarian/fallopian/peritoneal cancer. METHODS Our study included patients undergoing salpingoophorectomy or total hysterectomy and salpingoophorectomy for any gynecological pathology. Using a soft brush, fallopian tube smears from the fimbrial end were collected ex vivo. The Cytologists of our Institution described the morphological characteristics of the fallopian cells by adopting a proposed Table, which had a calibration system ranging from 3 to 29. This Table is referred to as the CytoSaLPs Score. Our study compared the two diagnostic cytological methods, the one of the conventional cytology and the other using the CytoSaLPs Score, having as gold standard the tubal's pathological findings. RESULTS A total of 230 tubal specimens from 144 patients were included in this study. The Score's mean for the benign and non-benign arm was 12.8 and 18.7 respectively. The cut-off point for both arms was 16.5. The CytoSaLPs Score tool showed significantly higher specificity (87.50% vs. 75.96, p-value < 0.001) and positive predictive value PPV (40.91% vs. 26.47%, p-value < 0.001) compared to conventional cytology. Regarding the accuracy, the Score's superiority is highlighted (86.96% vs. 76.52%, p-value < 0.001). CONCLUTIONS The evaluation of tubal cytology using the CytoSaLPs Score could be used as a reliable diagnostic method. Further evaluation with larger studies is warranted.

Abstract
With a 5-year survival rate of less than 50%, ovarian high-grade serous carcinoma (HGSC) is one of the most highly aggressive gynecological malignancies affecting women today. The high mortality rate of HGSC is largely attributable to delays in diagnosis, as most patients remain undiagnosed until the late stages of -disease. There are currently no recommended screening tests for ovarian cancer and there thus remains an urgent need for new diagnostic methods, particularly those that can detect the disease at early stages when clinical intervention remains effective. While diagnostics for ovarian cancer share many of the same technical hurdles as for other cancer types, the low prevalence of the disease in the general population, coupled with a notable lack of sensitive and specific biomarkers, have made the development of a clinically useful screening strategy particularly challenging. Here, we present a detailed review of the overall landscape of ovarian cancer diagnostics, with emphasis on emerging methods that employ novel protein, genetic, epigenetic and imaging-based biomarkers and/or advanced diagnostic technologies for the noninvasive detection of HGSC, particularly in women at high risk due to germline mutations such as BRCA1/2. Lastly, we discuss the translational potential of these approaches for achieving a clinically implementable solution for screening and diagnostics of early-stage ovarian cancer as a means of ultimately improving patient outcomes in both the general and high-risk populations.

Abstract
Falloposcopy is the endoscopic examination of the fallopian tubes, which are challenging to access due to their deep body location, small opening from the uterus, and lumen filled with plicae. We and others have developed endoscopes that are inserted through the uterus guided by a hysteroscope into the tubal ostium. To better understand how to utilize these endoscopes either as standalone devices or in concert with everting delivery balloons, a preliminary study of anatomy and mechanical behavior was performed ex vivo on porcine and human fallopian tubes. Segments of fallopian tubes from the isthmus, ampulla and infundibulum were inflated with saline either to bursting or held at sub-burst pressures with saline or a saline-filled balloon. Formalin fixed, paraffin embedded tissue sections stained with Masson's trichrome were examined for damage to the mucosa and muscularis. Porcine fallopian tubes tolerated saline pressurization at 15 psi for 1 minute without morphological damage. Balloon inflation to 15 psi caused no apparent damage to the muscle layer or rupture of the fallopian tube, but balloon movement within the tube can denude the mucosal epithelial layer. Human fallopian tubes averaged higher burst pressure values than porcine tubes. Under pressurization, the external tube diameter expanded by minimal to moderate amounts. Human and porcine tissues were similar in histological appearance. These studies suggest that moderate pressurization is acceptable but will not appreciably expand the fallopian tube diameter. The results also indicate that pigs are a reasonable model to study damage from falloscopy as seen in human tissue.

The Role of Genital Tract Microbiome in Fertility: A Systematic Review. Int J Mol Sci 2021; 23:ijms23010180.

Abstract
The human microbiome plays a crucial role in determining the health status of every human being, and the microbiome of the genital tract can affect the fertility potential before and during assisted reproductive treatments (ARTs). This review aims to identify and appraise studies investigating the correlation of genital microbiome to infertility. Publications up to February 2021 were identified by searching the electronic databases PubMed/MEDLINE, Scopus and Embase and bibliographies. Only full-text original research articles written in English were considered eligible for analysis, whereas reviews, editorials, opinions or letters, case studies, conference papers, and abstracts were excluded. Twenty-six articles were identified. The oldest studies adopted the exclusive culture-based technique, while in recent years PCR and RNA sequencing based on 16S rRNA were the most used technique. Regardless of the anatomical site under investigation, the Lactobacillus-dominated flora seems to play a pivotal role in determining fertility, and in particular Lactobacillus crispatus showed a central role. Nonetheless, the presence of pathogens in the genital tract, such as Chlamydia trachomatis, Gardnerella vaginalis, Ureaplasma species, and Gram-negative stains microorganism, affected fertility also in case of asymptomatic bacterial vaginosis (BV). We failed to identify descriptive or comparative studies regarding tubal microbiome. The microbiome of the genital tract plays a pivotal role in fertility, also in case of ARTs. The standardization of the sampling methods and investigations approaches is warranted to stratify the fertility potential and its subsequent treatment. Prospective tubal microbiome studies are warranted.

Abstract
Objectives: Recent research shows that most high grade ovarian cancer (OC) originates from the fallopian tube (FT). Cytologic evaluation of FT cells may enable early detection of OC. Material and Methods: This was a prospective study with patients enrolled from 3 centers (October 2016– August 2017). Forty-two women undergoing salpingo-oophorectomy for a pelvic mass suspicious for malignancy or undergoing risk-reducing surgery for BRCA mutations were included in the study. At the time of scheduled surgery, a novel catheter was used to collect FT cells through hysteroscopy. A pathologist blinded to surgical or pathologic findings evaluated FT cytology, and results were compared to pathology. Results: Of the 61 samples collected, 72% (44/61) met the adequacy criteria (≥5 clusters of cells with 20 cells in each cluster). Cytology classification criteria were established and applied to adequate samples. Forty-four samples were benign with mixed population of cells with round, oval, and spindled nuclei; 2-dimensional clusters; columnar cell configuration; flat sheets; cilia presence; no/mild nuclear pleomorphism; no nuclear membrane irregularities; and no nucleoli. Five samples had benign features with reactive nuclear and cytoplasmic changes and/or background inflammation, which were categorized as “reactive atypia.” Two malignant samples had features of 3-dimensional (3D) clusters, loss of mixed population of cells; increased nuclear/cytoplasmic ratio; nuclear membrane irregularity and nucleoli presence. Three samples with some but not all of malignant features were categorized as “neoplastic” (anisonucleosis; small nucleoli and features suggestive of 3D clusters). Malignant/ neoplastic samples were labeled as “Positive” (n = 5) while benign/reactive samples were labeled as “Negative” (n = 39). A high concordance rate (95%, 42/44) was observed between cytology results and histology. Conclusions: We characterized cytologic features for pathologically distinct FT samples collected in vivo using a novel catheter and demonstrated its value in detecting OC.

Abstract
Ovarian cancer is the third most common gynaecological malignancy and the most lethal worldwide. Most patients are diagnosed with advanced disease which carries significant mortality. Improvements in treatment have only resulted in modest increases in survival. This has driven efforts to reduce mortality through screening. Multimodal ovarian cancer screening using a longitudinal CA125 algorithm has resulted in diagnosis at an earlier stage, both in average and high risk women in two large UK trials. However, no randomised controlled trial has demonstrated a definitive mortality benefit. Extended follow up is underway in the largest trial to date, UKCTOCS, to explore the delayed reduction in mortality that was noted. Meanwhile, screening is not currently recommended in the general population Some countries offer surveillance of high risk women. Novel screening modalities and longitudinal biomarker algorithms offer potential improvements to future screening strategies as does the development of better risk stratification tools.

Abstract
High-grade serous carcinoma (HGSC) is the most common and lethal subtype of ovarian carcinoma. Many HGSCs are now believed to originate in the fallopian tube epithelium; ovarian surface epithelium is another possible origin. Thus, current screening methods, i.e., ultrasonography and serum CA-125 measurements, have a limitation in their early detection. Recently, circulating biomarkers, such as tumor DNA, autoantibody, and microRNA, have been investigated to detect HGSCs. As cancer cells in the fallopian tube flow into the endometrial cavity, the detection of exfoliated cells, tumor DNA, and proteome from samples obtained from the endometrial cavity or the cervix may be useful. The risk of ovarian serous carcinoma is affected by the use of oral contraceptive and menopausal hormone therapy (MHT). MHT regimens causing endometrial bleeding increase serous carcinoma risk, hence, incessant retrograde bleeding from the endometrial cavity into the Douglas pouch appears to play an important role in high-grade serous carcinogenesis. In this review, we provide an overview of current and novel screening methods and prevention approaches for ovarian and fallopian tube HGSC.

Abstract
OBJECTIVE To assess the feasibility of a novel hysteroscopic catheter to collect fallopian tube cytologic samples and to correlate cytologic findings with histopathology. METHODS This was a prospective, multicenter, single-arm pilot study. Women undergoing salpingo-oophorectomy for a pelvic mass suspicious for malignancy or for prevention of cancer for BRCA mutation carriers were recruited from 3 gynecologic oncology centers (October 2016-August 2017). Cytologic samples were collected from the fallopian tube using a novel FDA-cleared hysteroscopic catheter and evaluated by a pathologist blinded to surgical or pathologic findings. The correlation between cytologic results and final surgical pathology was assessed. RESULTS Of the 50 patients enrolled, 42 were eligible. Hysteroscopies were completed in 40 patients with 78 fallopian tubes, of which 65 ostia (83%) were identified. Of these, 61 (72%) were successfully catheterized resulting in 44 (68%) cytology samples adequate for further evaluation: 5 were classified as positive (3 neoplastic and 2 malignant) and 39 as negative (34 benign and 5 reactive/atypical). A comparison of cytology results with fallopian tube histopathology showed a concordance rate of 95% (42/44). Of the two samples with discordant results, both had positive cytology but negative tubal pathology, and both were stage I ovarian cancers with malignant ovary histology. CONCLUSIONS Deployment of the device yielded an evaluable cytologic sample in 68% of cases with a high rate of concordance with histopathology. Further evaluation of the device's ability to detect malignancy in high risk populations is warranted.

Abstract
PURPOSE OF REVIEW Both conventional and novel approaches to early detection of ovarian cancer are reviewed in the context of new developments in our understanding of ovarian cancer biology. RECENT FINDINGS While CA125 as a single value lacks adequate specificity or sensitivity for screening, large studies have shown that a 2-stage strategy which tracks CA125 change over time and prompts transvaginal ultrasound (TVS) for a small subset of women with abnormally rising biomarker values achieves adequate specificity and detects a higher fraction of early-stage disease. Sensitivity could clearly be improved in both blood tests and in imaging. Metastasis can occur from ovarian cancers too small to increase blood levels of protein antigens and a significant fraction of ovarian cancers arise from the fimbriae of fallopian tubes that cannot be imaged with TVS. Autoantibodies, miRNA, ctDNA, DNA methylation in blood, and cervical mucus might improve sensitivity of the initial phase and magnetic relaxometry and autofluorescence could improve imaging in the second phase. Enhancing the sensitivity of two-stage strategies for early detection could reduce mortality from ovarian cancer.

Abstract
OBJECTIVE To evaluate in a prospective pilot study the feasibility of cytobrushing of the fimbrial end using a transvaginal endoscopic access. STUDY DESIGN Prospective feasibility study. The procedure was performed in a consecutive series of 15 infertile women referred for a transvaginal laparoscopy as part of their fertility investigation. Tubal cells were collected using a 5Fr cytobrush. Cytology and immunocytochemistry was done. RESULTS In all patients enough cell material was obtained for analysis, without traumatizing the fimbrial end. Specimens showed the presence of a sufficient amount of cells enabling standard cytologic examinations and immunocytochemistry (Ki 67, p53). CONCLUSION Fimbrial cytobrushing using the transvaginal approach is an easy and minimally invasive procedure. The easy accessibility of the fimbrial end and the distal ampullary part at TVL allows an accurate collection of tubal epithelial cells. In view of the recent data reporting the Fallopian tube and more specifically the fimbrial end as a possible origin of ovarian carcinoma, further research is needed to evaluate the potential of this technique as a possible screening method for patients at risk for ovarian cancer.

Abstract
The lethality of epithelial ovarian cancer (EOC) may be due to common misconceptions regarding etiology and the absence of effective screening and early diagnostic tools. Reviews of histopathological surveys performed on the resected fallopian tubes of breast cancer (BRCA) mutation carriers, who underwent risk-reducing salpingo-oophorectomy, unexpectedly revealed the presence of occult carcinomas of the fallopian tubes. This finding prompted studies that demonstrated the most accredited theory of type II EOC development, which suggests that a large proportion of these tumors are derived from the fallopian tube. At present, no diagnostic tools or screening programs have been demonstrated to be effective or cost-effective in improving the outcome of EOC; it is therefore imperative that the scientific community unite its efforts in the identification of a valid screening and/or early diagnostic method for the treatment of this lethal gynecological malignancy. To this end, the present paper proposes a novel tool for the screening/early diagnosis of EOC: The 'Tuba-check'. This novel approach is based on the possibility of acquiring specimens for tubal lumen cytology via hysteroscopy in a minimally-invasive outpatient setting. The present study protocol aimed to validate the technical feasibility and oncological accuracy of the proposed approach, commencing with a cohort of patients with an expected increased oncological risk, including BRCA mutation carriers or those with a gene expression profile of 'BRCA-ness'. If the data collected by the present study protocol validates this approach, the 'Tuba-check' may, in the near future, be extended for the treatment of all women, therefore reducing the number of victims of epithelial ovarian carcinoma.

Abstract
A recent hypothesis has stated that many ovarian cancers (especially high-grade serous histotype) could arise from the distal part of the fallopian tube. On one hand we know that risk-reducing salpingo-oophorectomy is the most effective prevention for ovarian cancer among BRCA mutation carriers. On the other, oophorectomy increases the relative risk for cardiovascular, osteoporotic psychosexual and cognitive dysfunctions in premenopausal women. This raises the question whether bilateral salpingectomy could be an effective strategy in the prevention of ovarian cancer in case of hereditary predisposition and in the general population. Here we discuss origin of ovarian cancer in the light of the latest molecular studies and the relative risks and benefits of a strategy of exclusive salpingectomy in comparison with the classical adnexectomy.

Abstract
INTRODUCTION Fallopian tube intraepithelial cancer is a postulated precursor of epithelial ovarian carcinomas. As research continues on epithelial ovarian carcinomas' developmental pathways, representative tubal tissue must be procured for diagnostic, biological, and molecular studies without compromising pathological diagnosis. MATERIALS AND METHODS Fallopian tube fimbrial epithelia were harvested from postmenopausal women undergoing surgery for non-neoplastic gynecologic lesions (n = 16) and epithelial ovarian carcinomas (n = 6). Cytological imprints and washings were obtained from each fimbria and stained by Diff-Quik and rapid Papanicolaou for general cytomorphology; by Trypan blue for cell viability; and by rapid immunohistochemistry for evaluation of low molecular weight cytokeratin, MIB-1, p53, and high-mobility group A (HMGA2) expression. RESULTS Benign and malignant tubal imprints harvests yielded means of 3.5 × 105 and 1.2 × 106 cells/fimbria, respectively, with viabilities higher than 85%. A mean of 2.5 × 105 cells/fimbria was obtained from fimbrial washings. The mean DNA, RNA, and protein contents of benign imprints were 2.4, 1.5, and 67 μg/fimbria, respectively. Benign cell populations contained nearly 97% cytokeratin-positive and p53/HMGA2-negative cells, which were dispersed within a watery to proteinaceous material and rare microcalcifications. Fimbrial imprints from serous carcinomas involving the fimbriae exhibited abnormal p53 and HMGA2 expression, high proliferation, and diagnostic criteria of malignancy, including prominent nucleoli and cell crowding. CONCLUSIONS Ex vivo harvest from operative specimens allows for collection of cell populations representative of native fimbrial epithelium and free of significant contaminants. Tubal harvest facilitates triaging of cellular material for basic, clinical, and translational studies on cancer pathobiology and also represents a potential diagnostic adjunct to emerging in vivo high-resolution optical technologies.
