Possible metastatic routes via portacavalshunts in renal adenocarcinoma with liver metastasis

High recurrence rate after atypical resection for pancreatic metastases from renal cell carcinoma

“…The pancreas is a rare site of solitary metastasis, but is often involved in diffuse metastatic disease4. The behaviour of RCC metastasis is unusual and not well understood5–7. Among patients who had resection of RCC and survived for 10 years, more than 10 per cent had late metastases8.…”

Metástasis pancreática única de carcinoma renal

“…Hasta una cuarta parte de los casos puede presentar metástasis en el momento del diagnóstico y la frecuencia de metástasis a distancia tras una nefrectomía radical puede llegar al 11% 8,9 y, según algunos autores, hasta el 20-30% 1 . El carcinoma renal presenta metástasis con más frecuencia en pulmón, hueso, hígado, cerebro y glándulas suprarrenales y son raras las metástasis en piel, tiroides o páncreas 10,11 .…”

Renal cell carcinoma with metastasis to the pancreas: a case report and literature review

“…However, it is often clear from a properly conducted contrast-enhanced CT scan that a pancreatic lesion is hypervascularized and therefore most unlikely to represent primary pancreatic cancer. The mode of spread of RCC to the pancreas is controversial and can be either hematogenous or lymphatogenous [12,13]. Selective angiography may demonstrate hypervascularity [4,7].…”

“…Selective angiography may demonstrate hypervascularity [4,7]. Some metastases develop by venous spread via portocaval shunts [13]. Nagakawa's studies [12] showed that there are lymphatic routes from the head of the pancreas to the dorsal side of the renal artery.…”
