Aims and objectives
Malignant pancreatic tumors are common.
In patients with malignant pancreatic tumors five-year survival rate does not exceed 5% and the only radical treatment is surgery.
Due to early vascular invasion,
most of pancreatic tumors at the time of diagnosis are unresectable.
Up to 40-45% of patients with locally advanced pancreatic tumors at the time of diagnosis have liver metastases,
while the median survival in this group does not exceed 3-6 months.
Radical surgery is possible only in 5-25% of patients with malignant pancreatic tumors.
However,
the survival rate even after radical surgical treatment and aggressive chemotherapy remains extremely low - 5-year survival does not exceed 29% [1].
Nowadays,
cryoablation is a promising method of palliative treatment of locally advanced pancreatic cancer.
Cryosurgery is based on the effect of extremely low temperatures on the tumor tissue.
Some studies of ultra-low temperature effects on various tissues in vivo in vitro have proven the effectiveness of this technique [2-5].
Study purpose: to evaluate of the completeness of cryoablation (CA) in patients with malignant pancreatic tumors by imaging methods
