| 1905 H. D. Rolleston Dis. Liver 457 The term ‘hepatoma’ was suggested by Sabourin to describe the transitional stage between adenoma and carcinoma. 1912 Ibid. (ed. 2) 474 This condition [sc. primary carcinoma developing in a cirrhotic liver] was described..as Hepatoma by Rénon, Géraudel, and Monier-Vinard who insist that it is not a carcinoma. ‘Hepatoma’, also employed by Sabourin..is a confusing title. 1934 Brit. Jrnl. Surg. XXI. 684 The next advance of note was made by Yamagiura in 1911. He..made two simple divisions: (1) Hepatoma, i.e., carcinoma of hepatic cells; and (2) Cholangioma, i.e., carcinoma of bile-ducts. The term ‘hepatoma’ had previously been used by Sabourin in reference to a condition of nodular hyperplasia which in his opinion was a transitional stage between adenoma and carcinoma. Most modern writers, however, accept Yamagiura's interpretation, and use it as a term for primary carcinoma of the liver cells. 1971 New Scientist 17 June 668/3 From one strain of a mouse hepatoma they have a factor which they describe as being ‘a heat stable molecule of low molecular weight’. |
