title: [The biological behavior of exocrine pancreatic carcinoma from a pathological-anatomical viewpoint. A contribution to the problems of surgical therapy].
abstract: The general biologic behaviour of exocrine pancreatic cancer was examined retrospectively in a total of 840 autopsies (382 males, aged 31-86 [average 66.5] and 458 females, aged 2-90 [average 72]). 95 % of autopsies showed definable tumours (caput 64%, corpus 17%, cauda 14%), in 5% the gland was diffusely permeated by cancer tissue. 19.5% had no metastases, whereas in 80.5% carcinomatosis was diagnosed. In 7% only locoregional metastases of the lymph nodes could be found. Tumour sizes were observed in the range of 0.3 to 14 cm. All carcinomas below the size of 1 cm were free of metastases. In tumours larger than 2 cm, the formation of metastases increased sharply. In sizes more than 3 cm complications were important for the prognosis. Carcinomatosis proceeds cascade-fashion with high first rate metastatic spread into the liver. 6% of liver metastases were solitary ones, 94% were multiple. In 171 cases malignancy grading was performed. Free of metastases were 50% of the decreased with grade-I-carcinomas, 21% with grade-II-carcinomas and 7% with grade-III-carcinomas. These data comment on the possibilities and limitations of curative cancer resection from a morphological view.
