Doctors for treatment of Pancreatic cancer

International standards for the diagnosis and treatment of pancreatic cancer

Pancreatic cancer is often found incidentally during an examination (abdominal ultrasound). If suspected, the doctor prescribes further diagnostics. Find out if it is really a tumor, where exactly in the pancreas is located and how far the disease has gone.
Mandatory examinations are:

• laboratory tests,
• ultrasound examination (sonography),
• endoscopic ultrasound examination (endosonography).

Due to the position of the carcinoma in the pancreas, many imaging procedures do not provide detailed images. Therefore, they are often combined with:

• endoscopic imaging of the pancreatic duct and biliary tract using X-rays (ERCP),
• MRI, CT, X-ray,
• tissue puncture (biopsy),
• laparoscopy,
• positron emission tomography (PET),
• scintigraphy with octreotide.

Laboratory tests

Blood tests provide information about the general condition of a person, the functions of individual organs and the presence of tumor markers. They are produced by tumor cells of pancreatic carcinoma.

Sonography

With the help of ultrasound, the doctor checks the spread of the tumor in the surrounding tissues and daughter tumors (metastases) in distant organs. Disadvantages:

• Very small tumors (less than 1 cm in diameter) are not visible.
• Due to its location in the back of the abdomen, the pancreas is not always clearly visible from the outside.

Endosonography

Due to the close proximity to the tumor, the quality and information content of ultrasound images is much higher than in sonography. Endosonography can detect very small tumors (less than 5 millimeters in diameter). Using this method, the tumor can be punctured under ultrasound guidance.

Octreotide scintigraphy

This research method is based on the ability of tumor cells to bind octreoid on their surface. This substance is an active protein molecule. The patient is given an injection with this drug and waited for 24 hours. The accumulation of antibodies in the area of the tumor is detected externally using special devices.

Treatment

Treatment includes different methods:

• surgical removal of the tumor,
• radiochemotherapy,
• stereotactic irradiation,
• drug therapy,
• relief therapy.

Surgery option

Based on the localization of the neoplasm, the surgeon removes the entire pancreas or only part of the organ. Adjacent organs (biliary tract, duodenum, spleen) are removed when metastases are found in them. This increases the chances of recovery.

Stereotactic radiosurgery

With this method of treatment, tumor tissues are targeted with high individual doses. Patients also receive chemotherapy with active substances before radiation therapy. In some patients, chemotherapy continues after radiation therapy until the disease progresses.

The effectiveness of therapy: more than 80% of patients live for more than a year and in half of them the tumor does not progress.

Drug therapy

Suitable for patients:

• with local cancer,
• with inoperable cancer,
• with disseminated cancer.

A combination of the chemotherapeutic agent gemcitabine and the tyrosine kinase inhibitor erlotinib is used. These substances block the growth of tumor cells.
