FIELD: medicine; oncology; pathological anatomy.
SUBSTANCE: invention can be used for differential diagnosis of pancreatic cancer in patients with mass growth in pancreas after resection-draining operation for chronic pseudotumorous pancreatitis. For this purpose, during the resection-draining operation, pancreatic juice is sampled and placed in the Matrigel for cultivation. If tumor cells grow in Matrigel, pancreatic cancer is diagnosed.
EFFECT: invention enables to effectively diagnose the continued growth of a malignant tumor with underlying chronic pseudotumorous pancreatitis, preventing early metastasis to other organs, extending the indications for radical surgical intervention.
