Anatomic Pathology Abstracts, 7/17

July 2017—Potential quality indicators for lymph node staging of colon cancer: Evaluation of 12 or more lymph nodes is used as a quality indicator for adequacy of pathologic examination of colon cancer resections. The authors conducted a study to evaluate the utility of a focused lymph node search in the immediate vicinity of the tumor and a “second-look” protocol for improving lymph node staging in colon cancer.

Anatomic Pathology Abstracts, 6/17

June 2017—Fallopian tube involvement in uterine serous carcinomas: The authors investigated the frequency and histopathologic and immunohistochemical characteristics of tubal involvement in uterine serous carcinoma to clarify the relationship between serous tubal intraepithelial carcinoma (STIC) and uterine serous carcinoma. They prospectively collected and reviewed, for the presence of tubal involvement, cases of the latter with complete tubal examination.

Anatomic Pathology Abstracts, 5/17

May 2017—Value of Ki-67 proliferative index in WHO-classified pulmonary carcinoids; Chromosomal abnormalities and genetic changes in uterine smooth muscle tumors; Expression of divergent endodermal lineage markers in yolk sac tumors; Interobserver reproducibility of percent GP4 in prostatic adenocarcinoma on biopsies; MELF pattern invasion: a report of FIGO grade 1 endometrial endometrioid adenocarcinomas; Cost-effectiveness of identifying H. pylori  in gastric biopsies without ancillary stains

Anatomic Pathology Abstracts, 4/17

April 2017—Proposing prognostic thresholds for lymph node yield in oral cavity cancers: Prognostic lymph node yield thresholds have been identified and incorporated into treatment guidelines for multiple cancer sites, but not for oral cancer. The authors conducted a study to identify optimal thresholds in elective and therapeutic neck dissection for oral cavity cancers.

Anatomic Pathology Abstracts, 3/17

March 2017—An immunohistochemical algorithm for ovarian carcinoma typing: Five major histotypes of ovarian carcinoma exist. Diagnostic typing criteria have evolved over time, and past cohorts may be misclassified by current standards. The authors undertook an endeavor to reclassify the recently assembled Canadian Ovarian Experimental Unified Resource and Alberta Ovarian Tumor Type cohorts using immunohistochemical (IHC) biomarkers and to develop an IHC algorithm for ovarian carcinoma histotyping.

February 2017—Findings in hysterectomy specimens of women with Lynch syndrome; Percentages and architectural types of Gleason pattern 4 cancer in radical prostatectomy; PTEN loss and chromosome 8 alterations in Gleason grade 3 prostate cancer cores; Lymph node count from neck dissection predicts mortality in head and neck cancer; Assessing the adequacy of lymph node yield for papillary thyroid cancer; Addressing perceived versus actual agreement in breast pathology interpretation; Cost-effectiveness of Oncotype DX DCIS score for guiding treatment of DCIS

Anatomic Pathology Abstracts, 1/17

January 2017—Drawbacks of reflex ER and PR analysis of DCIS in breast needle core biopsies; Analysis of eosinophils and mast cells of gastrointestinal tract in healthy children; Classifying gastric cancer into molecular subgroups; Clinicopathologic significance of mismatch repair defects in endometrial cancer; Use of immunostains to distinguish hepatic adenoma from hepatocellular carcinoma; Prognostic effect of PD-L1 expression patterns in cervical cancers; Variation in pattern-based classification of invasive endocervical adenocarcinoma

Anatomic Pathology Abstracts, 12/16

December 2016—Reproducibility of NEPTUNE descriptor-based scoring system with various types of images: The multicenter Nephrotic Syndrome Study Network, or NEPTUNE, digital pathology scoring system uses a novel and comprehensive methodology to document pathologic features from whole-slide images, immunofluorescence, and ultrastructural digital images.

Anatomic Pathology Abstracts, 11/16

November 2016—Relevance of papillary growth patterns of pulmonary adenocarcinoma, HPV involvement in head and neck cancers: assessment of biomarkers, Distinctive immunoregulatory microenvironment of medullary carcinoma of the colon, Diagnostic challenges caused by endoscopic biopsy of colonic polyps, MicroRNA expression profiling and expression of miR-205 in inflammatory breast cancer

Anatomic Pathology Abstracts, 10/16

October 2016—Features of columnar-lined esophagus in gastroesophageal junction biopsies; Significance of Paneth cells in histologically unremarkable rectal mucosa; MicroRNA expression profile related to lymph node status in endometrial cancer; Plasma cells in melanoma: prognostic significance and possible role of IgA; Human epidermal growth factor receptor 2 testing in invasive breast cancer
