Revolutionizing Cancer Detection with Non-Invasive Imaging Instruments

In today’s biotechnology-driven world, early and accurate cancer diagnosis is critical to improving patient outcomes. From high-throughput sequencers to advanced cytometry platforms, cutting-edge laboratory instruments play a vital role in identifying cancer biomarkers, detecting mutations, and guiding personalized treatment strategies.

Used for:

All solid tumors: Biopsy preparation and diagnosis
Lung, liver, breast, prostate cancers: Core and surgical biopsy processing

12. Radiological Imaging Fusion Tools

Software that combines molecular imaging (e.g., SPECT or PET) with anatomical scans (MRI, CT) for more precise localization of cancer.

Used for:

Prostate cancer: PSMA-targeted imaging (e.g., ProstaScint-based scans)
Lymphomas: PET-CT for metabolic activity
Neuroendocrine tumors: SPECT for somatostatin receptor mapping

The only approved imaging agent that specifically targets prostate cancer.ProstaScint is the only commercially available diagnostic imaging agent approved by the FDA that specifically targets prostate cancer cells that have spread to tissue outside of the prostate gland. It consists of a novel murine monoclonal antibody that, when conjugated to a linker-chelator and radiolabeled, binds distinctly to Prostate Specific Membrane Antigen (PSMA). PSMA is a glycoprotein expressed by prostate epithelium, which is up regulated in prostate cancer. PSMA is expressed on metastatic prostate cancer tissue. Combined with a CT or MRI scan, this fusion imaging study helps to determine the location and extent of metastatic lymph node disease. Knowing whether the prostate cancer is confined to the gland or has spread to the lymph nodes helps physicians determine appropriate patient management.

🧪 What is ProstaScint?

ProstaScint is a medical imaging tool. It is used to find prostate cancer that has spread (metastasized) beyond the prostate gland especially to lymph nodes.

It is not a treatment it helps doctors see where the cancer is, so they can decide on the best treatment.

🔬 What is it made of?

ProstaScint is made of two key parts:

A special antibody this is like a "homing missile" that looks for PSMA, a molecule found in large amounts on prostate cancer cells.
A radioactive label this is a tiny radioactive tag that allows imaging machines to "see" where the antibody goes in the body.

Together, these parts let doctors track prostate cancer cells that are hiding outside the prostate, like in lymph nodes or other tissues.

🧠 Why is this useful?

Many men with prostate cancer need to know if their cancer is:

Still inside the prostate (localized),
Has spread to lymph nodes or beyond (metastatic)

ProstaScint helps doctors:

Make this distinction
Choose the right treatment ( surgery, radiation, or systemic therapy)
Avoid unnecessary treatments if the cancer has already spread

How does the imaging work?

Here’s how it works step by step:

The doctor injects ProstaScint into the patient's body.
The antibody travels through the bloodstream and sticks to prostate cancer cells (because of the PSMA).
The radioactive tag shows up on scans like CT or MRI, so doctors can see where the cancer is located.

Product Attributes

The only imaging agent that specifically targets prostate cancer cells

Approved by the US FDA in both newly diagnosed, high risk patients, and patients suspected of having recurrent disease

American Cancer Society specifically recognizes ProstaScint in current prostate cancer diagnosis guidelines

ProstaScint Indications for Use:

ProstaScint (Capromab Pendetide) is indicated as a diagnostic imaging agent in newly-diagnosed patients with biopsy-proven prostate cancer, thought to be clinically-localized after standard diagnostic evaluation (eg chest x-ray, bone scan, CT scan, or MRI), who are at high-risk for pelvic lymph node metastases. It is not indicated for patients who are not at high risk.
ProstaScint is also indicated as a diagnostic imaging agent in post-prostatectomy patients with a rising PSA and a negative or equivocal standard metastatic evaluation in whom there is a high clinical suspicion of occult metastatic wellness. The imaging performance of Indium In 111 ProstaScint following radiation therapy has not been studied.
The information provided by Indium In 111 ProstaScint imaging should be considered in conjunction with other diagnostic information. Scans that are positive for metastatic wellness should be confirmed histologically in patients who are otherwise candidates for surgery or radiation therapy unless medically contraindicated. Scans that are negative for metastatic wellness should not be used in lieu of histological confirmation.
ProstaScint is not indicated as a screening tool for carcinoma of the prostate nor for readministration for the purpose of assessment in response to therapy.

Contraindications:

Indium In 111 ProstaScint should not be used in patients who are hypersensitive to this or any other product of murine origin or to Indium In 111 chloride.

Warnings:

Patient management should not be based on Indium In 111 ProstaScint (Capromab Pendetide) scan results without appropriate confirmatory studies since in the pivotal trials, there was a high rate of false positive and false negative image interpretations .
ProstaScint images should be interpreted only by physicians who have had specific training in Indium In 111 ProstaScint image interpretation .
Allergic reactions, including anaphylaxis, can occur in patients who receive murine antibodies. Although serious reactions of this type have not been observed in clinical trials after Indium In 111 ProstaScint administration, medications for the treatment of hypersensitivity reactions should be available during administration of this agent.
ProstaScint may induce human anti-mouse antibodies which may interfere with some immunoassays, including those used to assay PSA and digoxin . keep the same contenu but make it more seo optimized

ProstaScint gives us a functional view, not just a structural one and that makes all the difference in early detection of metastasis
