The objective of this retrospective observational study was to investigate the impact of fecal occult blood test (FOBT) as colorectal cancer (CRC) screening by primary tumor location. We compared the risk of requiring treatment for advanced disease and total medical costs per patient between CRC patients who underwent FOBT within 1 year before initial treatment for CRC and those who did not, using the JMDC Claims database, large-scale health insurance claims and checkup data in Japan. Treatment for advanced disease was defined as (1) nonendoscopic therapy or (2) chemotherapy or radiotherapy, performed during the follow-up period.

Intestinal adhesion is one of the complications that occurs more frequently after abdominal surgery. Postsurgical intestinal adhesion (PIA) can lead to a series of health problems, including abdominal pain, intestinal obstruction, and female infertility. Currently, hydrogels and nanofibrous films as barriers are often used for preventing PIA formation; however, these kinds of materials have their intrinsic disadvantages.

Purpose: Patients with aggressive thyroid cancer are frequently failed by the central therapy of ablative radioiodide (RAI) uptake, due to reduced plasma membrane (PM) localization of the sodium/iodide symporter (NIS). We aimed to understand how NIS is endocytosed away from the PM of human thyroid cancer cells, and whether this was druggable in vivo.

Experimental Design: Informed by analysis of endocytic gene expression in patients with aggressive thyroid cancer, we used mutagenesis, NanoBiT interaction assays, cell surface biotinylation assays, RAI uptake, and NanoBRET to understand the mechanisms of NIS endocytosis in transformed cell lines and patient-derived human primary thyroid cells.
