Colorectal (colon) cancer ranks second in terms of cancer lethality worldwide. It is estimated that approximately 1.93 million new colorectal (colon) cancer cases and approximate one million colorectal cancer deaths occur worldwide in 2020 alone. Cancer metastasis is a major source of cancer lethality. Mechanisms underlying colorectal cancer metastases are long-term obscure. Recently, a new organelle associated with aggressive cancer cells, dubbed cytocapsular tube, was recognized to conduct cancer cell metastases in tissues in vivo. Here, we investigated the roles of cytocapsular tubes in colon cancer metastasis in 9 subtypes of colon cancers with original clinical colon cancer tissues, paracancer tissues of colon cancer, and metastatic colon cancers in multiple other tissues and organs. We found that colon cancer metastasized via cytocapsular tubes and their networks in clinical tissues in vivo. Furthermore, we applied the cytocapsular tube analyses in precise cancer diagnosis in clinical colon cancers and obtained better outcomes in clinical colon cancer management.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
