Impact of Simultaneous Circulating Tumor DNA and Tissue Genotyping in the Workup of Stage IV Lung Adenocarcinoma on Quality of Care in an Academic Community Medical Center.

Purpose: In patients with metastatic lung adenocarcinoma, evidence-based first-line treatment decisions require analysis of tumors for genomic alterations (GAs). Optimizing the genotyping paradigm may improve the delivery of precision oncology care. Actionable GAs can be identified by analyzing tumor tissue or circulating tumor DNA using liquid biopsy.

Paraganglioma of the Spermatic Cord With Spinal Metastasis: A Case Report.

A 40-year-old male with presented to the clinic with the chief complaint of right inguinal pain radiating to his right testicle and right thigh with no history of trauma, fever, chills, dysuria, hematuria, or unprotected sexual activity. Physical exam revealed right testicular tenderness with no palpable abnormality of the bilateral testes or spermatic cords. Scrotal ultrasound was performed and was unremarkable for testicular or other intrascrotal pathology.

Correlation of positron emission tomography with fine needle aspiration biopsies in head and neck malignancy.

Objective: To investigate whether a correlation between fine needle aspiration cytology and positron emission tomography (PET) exists in the preoperative screening, staging and diagnosis of head and neck cancer.

Study Design: We retrospectively correlated fine needle aspiration biopsy (FNAB) and PET scan in patients with head and neck lesions.

Results: There were 92 FNABs with corresponding PET scan in 83 patients.

Guanylyl cyclase C is a specific marker for differentiating primary and metastatic ovarian mucinous neoplasms.

Aims: The aim was to assess the value of GCC in distinguishing primary ovarian mucinous neoplasms from metastatic mucinous adenocarcinomas with ovarian involvement. Guanylyl cyclase C (GCC) is a brush border membrane receptor for the endogenous peptides guanylin and uroguanylin, and the homologous diarrhoeagenic bacterial heat-stable enterotoxins that is selectively expressed by epithelial cells from the duodenum to the rectum, but not by normal epithelia of the stomach or oesophagus, or normal extramucosal cells in humans.

Methods And Results: Fifty ovarian tumours: 27 primary ovarian mucinous neoplasms (seven cystadenomas, 10 borderline tumours and 10 cystadenocarcinomas) and 23 metastatic mucinous adenocarcinomas with ovarian involvement [13 colorectal adenocarcinomas, four gastric adenocarcinomas, six appendiceal mucinous tumours (four adenocarcinomas, one with neuroendocrine features, and two appendiceal mucinous cystadenomas)] were studied.

The significance of GATA3 expression in breast cancer: a 10-year follow-up study.

GATA3 is a transcription factor closely associated with estrogen receptor alpha in breast carcinoma, with a potential prognostic utility. This study investigated the immunohistochemical expression of GATA3 in estrogen receptor alpha-positive and estrogen receptor alpha-negative breast carcinomas. One hundred sixty-six cases of invasive breast carcinomas with 10-year follow-up information were analyzed.

Cytologic accuracy of samples obtained by endobronchial ultrasound-guided transbronchial needle aspiration at Thomas Jefferson University Hospital.

Objective: To evaluate the diagnostic yield and cytologic accuracy of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in cases of clinically suspected epithelial malignancy, sarcoidosis and lymphoma.

Study Design: Over a 9-month period from inception at Thomas Jefferson University Hospital, a retrospective analysis of the cytologic diagnoses of all EBUS-TBNA procedures performed in 48 patients was undertaken. The patients were divided into 2 groups, those with clinical suspicion of an epithelial malignancy and those with clinical suspicion of sarcoidosis or lymphoma.

A prospective feasibility trial to determine the significance of the sentinel node gradient in breast cancer: a predictor of nodal metastasis location.

Background: Sentinel lymph node (SN) biopsy is standard for breast cancer staging, but SN dye gradients and their significance have never been characterized. If predictive of SN metastasis location, their use for focused pathology examination might improve intraoperative imprint cytology sensitivity.

Methods: This prospective trial enrolled clinically lymph node-negative patients with invasive breast cancer not undergoing neoadjuvant chemotherapy.
