Detection Of Progression Or Regression Of Breast Cancer By Circulating Tumor Dna (Ctdna), Ujjwal Karki, Bipin Ghimire, Emma Herrman, Siddhartha Yadav, Mohammad Muhsin Chisti

Conference Presentation Abstracts

Circulating tumor DNA (ctDNA) are short DNA sequences shed by tumor cells into the systemic circulation. Studies have shown potential utility of the test to predict relapse or recurrence following treatment in solid tumors, but sensitivity and specificity have varied widely, ranging from 19-100% and 80-100% respectively, in breast cancer specifically. Moreover, literature describing the utility of monitoring dynamic changes in ctDNA trends is limited. We aim to evaluate the correlation between ctDNA test, both single test as well as dynamic trends in value over time, with imaging findings.

Merkle Cell Carcinoma While On Rituximab - Is It A Coincidence?, Bana Antonios, Emma Herrman, Mohammad Muhsin Chisti

Conference Presentation Abstracts

A 79-year old woman with history of relapsed Stage II, grade III follicular lymphoma was treated with four cycles of rituximab and bendamustine with an excellent response. She was subsequently placed on maintenance rituximab infusions every eight weeks. Six months later, she presented to the dermatology clinic with a newly raised erythematous papule on her left cheek. Excisional biopsy confirmed a diagnosis of Merkel cell carcinoma which was resected with wide margins. Merkel cell carcinoma (MCC) is a rare aggressive skin malignancy, with a dramatic increase in incidence in the past few decades. It grows and metastasizes rapidly and diagnosis …

Hepatoid Adenocarcinoma Of Lung: A Rare And Challenging Tumor, Bipin Ghimire, Ashbina Pokharel, Samiksha Pandey, Ujjwal Jung Karki, Can Wang, Michael Stender

Conference Presentation Abstracts

Hepatoid adenocarcinoma (HAC) is an extremely rare extra-hepatic malignant tumor having hepatic features on pathology. Stomach is the most common site, and hepatoid adenocarcinoma of lung (HAL) accounts for 2.3 – 5% of all HACs. Less than 100 cases of HAL have been reported worldwide since its concept was put forward in 1990. A 63-year-old female presented to the ED with back pain. Initial evaluation revealed anemia (hemoglobin 6.7), hypercalcemia (12.1 mg/dl), GFR 54 mL/min. X-ray thoracic spine and chest showed two vertebral compression deformities and lytic lesions on multiple ribs. Initially, multiple myeloma was considered likely but further evaluation …

Detection Of Progression Or Regression Of Gynecologic Cancers By Circulating Tumor Dna (Ctdna), Bipin Ghimire, Ujjwal Karki, Emma Herrman, Mohammad Muhsin Chisti

Conference Presentation Abstracts

Objectives The use of post-operative circulating tumor DNA (ctDNA) to detect cancer recurrence has been reported in various studies but the literature describing variable changes in ctDNA is limited. The objective of this study is to describe the utility of single and serial ctDNA values in detecting the progression or regression of gynecological cancers.

Methods This is a retrospective observational study including nineteen patients, aged >=18 years who had the ctDNA test completed at hematology/oncology clinic of William Beaumont – Royal Oak and Troy Hospitals, Michigan, USA.

Results Among the nineteen patients, fifteen had breast, three had ovarian, and one …
