The presented clinical score may allow for patients with colorectal liver metastases to be stratified appropriately and for optimization of their subsequent therapeutic management.

TPTX+AT and TPTX seem to be safe and equally effective for the treatment of otherwise uncontrollable SHPT. TPTX seems to suppress PTH more effectively and showed no recurrences after 3 years. The hypothesis that TPTX is superior to TPTX+AT referring to the rate of recurrent SHPT has to be tested in a large-scale confirmatory trial. Nevertheless, TPTX seems to be a feasible alternative therapeutic option for the surgical treatment of SHPT.

Background: Pancreatic metastases from renal cell carcinoma (RCC) are clinically rare but highly resectable. The aim of this article is to identify patients who profit from pancreatic resection of RCC despite the invasiveness of the surgery. Methods: Between January 1996 and December 2007, data from 744 patients were collected in a prospective pancreatic surgery database, and patients with metastasis into the pancreas from RCC were identified. Results: Resective surgery was performed in 14 patients with metastasis to the pancreas from RCC. Most patients were clinically asymptomatic. The median interval between primary treatment of RCC and occurrence of pancreatic metastasis was 94 months (range 32–158). The morbidity rate was 42.8%. Patients with a metastasis size <2.5 cm had a much better survival after resection (100 months) than those with a metastasis size >2.5 cm (44 months). Moreover, the number of metastases predicts the survival after resection. Conclusions: In patients with pancreatic metastases from RCC who have only limited disease, complete resection of all lesions can be successfully performed with a low rate of complications. Thus, patients with a history of RCC should be monitored for more than 10 years after nephrectomy to detect recurrence.

The indication for resection of metastases can be safely extended to cases in which tumors sit closer than 1 cm to nonresectable structures.

The results of our study support the existence of the "streaming" effect in the portal vein. Right-sided colon carcinomas predominantly involve the right hemiliver, while left-sided colon carcinomas involve the liver homogeneously, considering the size ratio of the right to left liver lobe, which is about 2:1. Knowledge of streaming may help us to understand the spread of abdominal malignancies and may provide a reference concerning the possible primary site depending on metastatic distribution in the liver.
