Processing of fallopian tube, ovary, and endometrial surgical pathology specimens: A survey of U.S. laboratory practices.

ABSTRACT: OBJECTIVE:Many high-grade serous carcinomas initiate in fallopian tubes as serous tubal intraepithelial carcinoma (STIC), a microscopic lesion identified with specimen processing according to the Sectioning and Extensive Examination of the Fimbria protocol (SEE-Fim). Given that the tubal origin of these cancers was recently recognized, we conducted a survey of pathology practices to assess processing protocols that are applied to gynecologic surgical pathology specimens in clinical contexts in which finding STIC might have different implications. METHODS:We distributed a survey electronically to the American Society for Clinical Pathology list-serve to determine practice patterns and compared results between practice types by chi-square (?2) tests for categorical variables. Free text comments were qualitatively reviewed. RESULTS:Survey responses were received from 159 laboratories (72 academic, 87 non-academic), which reported diverse specimen volumes and percentage of gynecologic samples. Overall, 74.1% of laboratories reported performing SEE-Fim for risk-reducing surgical specimens (82.5% academic versus 65.7% non-academic, p?

Project description:ObjectivesRecent 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 methodsThis 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.ResultsOf 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.ConclusionsWe characterized cytologic features for pathologically distinct FT samples collected in vivo using a novel catheter and demonstrated its value in detecting OC.
