Our findings indicate that P504S is a highly sensitive and specific positive marker for prostate carcinoma.
What is high grade prostatic intraepithelial neoplasia?
HGPIN refers to proliferation of prostate glandular epithelial cells that display significant cytological atypia within the confines of prostatic ducts and acini. 2. It has been accepted as the main precursor lesion to invasive prostate carcinoma.
What is adenocarcinoma prostate?
An adenocarcinoma is a type of cancer that arises in the cells of glands. Most cells in the prostate gland are of the glandular type, which means that adenocarcinoma is the most common type of cancer to occur in the prostate.

Immunostaining with high molecular weight cytokeratin (HMWCK) confirms the absence of basal cells in the smaller atypical glands supporting the diagnosis of adenocarcinoma. The most commonly used antibodies include 34bE12, CK5/6, and CK14.
What does positive for Racemase mean?
Positive racemase staining converts an atypical diagnosis, based on suspicious histology and negative basal cell marker stains, to cancer in approximately 10% of cases thought to be atypical by contributing pathologists, and in approximately 50% of cases thought to be atypical by a specialist in genitourinary pathology …
What are adenocarcinoma cells?

It develops in the gland cells that make prostate fluid. Prostate cancer is second only to skin cancer as the most common cancer in men in the United States.
What does atypical small acinar proliferation mean?
This is referred to as atypical small acinar proliferation (ASAP). ASAP, which is defined as a focus of small acinar structures formed by atypical epithelial cells, is a condition in which the pathologist has insufficient data to make a diagnosis and thus raises the suspicion of cancer.
What does Napsin a stain?
Immunohistochemistry (IHC) for thyroid transcription factor-1 (TTF-1) is used to confirm the diagnosis of lung adenocarcinoma. Napsin A also has shown positivity in lung adenocarcinoma. A combined double stain for TTF-1 and napsin A has been proposed to achieve higher sensitivity and specificity.
How is adenocarcinoma caused?
Tobacco use is the primary cause of adenocarcinoma and other types of cancer. Toxin exposure. Harmful toxins in your home or work environment can also cause adenocarcinoma. Previous radiation therapy.
What is the difference between adenocarcinoma and neuroendocrine?
While each type of tumor can spread (metastasize) from the pancreas to other organs, pancreatic neuroendocrine tumors usually spread over a period of years. Pancreatic adenocarcinoma, on the other hand, typically spreads over a period of months.

Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with Sun’Agri and INRAE in Avignon between 2019 and 2022. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. I love to write and share science related Stuff Here on my Website. I am currently continuing at Sun’Agri as an R&D engineer.
