eye

An eye cancer of infants caused by loss of the RB1 gene, the first tumour-suppressor gene ever found. In rich countries almost every child survives and most eyes are saved by chemotherapy delivered through the eye's artery; in low-income countries, where most cases occur, survival depends on finding it early, and that is the global gap.

A melanoma inside the eye that is biologically unrelated to skin melanoma: different mutations, no response to standard immunotherapy, and a tendency to spread to the liver years later. Tebentafusp is the first drug ever to extend survival in the metastatic disease.
