Morphological assessment of the prevalence of ductal adenocarcinoma of the pancreas

To systematize the concept of "surgical margin" with ductal carcinoma pancreas to determine the prognostic value of regional lymph node and perineural invasion in these patients. Results. Status R1 pancreatic cancer detected in 69,1% (38/55), while often affects the medial and anterior surface - 14,5% and 9% (8/38 and 5/38), respectively. By the number of positive margins: 1 surface - 27,3 % (15/38), both surfaces - 35,5% (19/38) and 3- surfaces - 7,3% (4/38). Conclusions: ductal carcinoma in the pancreas along with direct tumor spread should provide locoregional spread and mixed (a combination of direct and locoregional). Undoubtedly, reliably identify R0 resection is impossible without improvement and standardization of protocols mortem examinations.
