Colorectal cancer(CRC) is a common malignancy worldwide. In CRC patients, metastases are the main cause of cancer-related mortality. In a group of metastatic CRC patients, the metastases are limited to a single site(solitary organ); the liver and lungs are the most commonly involved sites. When metastatic disease is limited to the liver and/or lungs, the resectability of the metastatic lesions will dictate the management approach and the outcome. Less commonly, the site of solitary organ CRC metastasis is the peritoneum. In these patients, cytoreduction followed by hyperthermic intraperitoneal chemotherapy may improve the outcome. Rarely, CRC involves other organs, such as the brain, bone, adrenals and spleen, as the only site of metastatic disease. There are limited data to guide clinical practice in these cases. Here, we have reviewed the disease characteristics, management approaches and prognosis based on the metastatic disease site in patients with CRC with metastases to a single organ.

This paper quantifies the regional economic contributions of coal exports from the US using a case study of Signal Peak Energy in Montana. Two methods of estimating economic contributions are compared, contribution and impact analysis. The latter is adopted because the industry impact analysis is more accurate, especially since it is based upon accounting records from Signal Peak. Our estimates of regional economic and fiscal impacts do not vary significantly with the price of coal because we explicitly account for swings in royalty income. Our analysis finds that Signal Peak Energy supports 678 jobs, over $55 million in tax revenues, more than $90 million in royalties, $111.7 million in value added, and $62.3 million in labor income. Curtailing or halting Signal Peak’s coal production for environmental reasons as some environmental groups have argued would eliminate these economic contributions.
