Clinical uses of radiopharmaceuticals imply the administration of radioactive substances that are mainly excreted through urine. The Nuclear Medicine Department at the Instituto Nacional de Cancerología (INC-COL) in Bogota, Colombia, administers radiopharmaceuticals for diagnostics and treatment to many patients, resulting in tens of cubic meters of radioactive waste water (WW) every day. As Colombian regulatory limits for liquid radioactive discharges to the sewer system are lower than in other countries, longer WW decay times are required, even when an in-house waste water treatment plant (WWTP) is used...

Cholangiocarcinoma is a low-frequency neoplasm of onset with a poor prognosis. Peritoneal carcinomatosis is the most frequent site of metastasis with a standard palliative chemotherapy treatment. In the present article, we describe the case of a 35-year-old woman with peritoneal carcinomatosis secondary to an intrahepatic cholangiocarcinoma who was treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) as a non-standard therapeutic method. The patient has disease-free survival of 12 months with very good quality of life...
