What if the sacrococcygeal teratomas that we worry most about are actually the least aggressive ones? I'm Lizzie Lee from Cincinnati Children's, and this is an article you should know about. This multi-center review looked at over 200 sacrococcygeal teratoma cases and compared kids with Corino's syndrome to those without it. The difference. are dramatic. Corino patients were almost always diagnosed after birth, and their tumors are almost exclusively Altmann type 4, buried deep in the pelvis. Every tumor in the curorinal group was a mature one. There were no immature or malignant components at all. They were also much smaller, around 3 centimeters instead of 8. Recurrence was almost nonexistent and not significantly different from non-curachino cases. So the message here is that curorino associated sacrococcygeal teratomas behave incredibly well oncologically, which means we may be able to rethink how aggressively we follow these kids long term. Let us know what you think in the comments below and stay tuned for more articles that you should know about.
