To the Editor.–In a recent article entitled "An Evaluation of the Staging Laparotomy in Hodgkin's Disease" (Archives 1980;115:694-695), the authors expressed a belief that the routine use of staging laparotomy is not indicated in Hodgkin's disease.
I was taken aback by the lack of knowledge regarding proposed definitions in the article and in the editorial comment. Mantle technique, by definition,1-3 is radiotherapy encompassing all major lymph node chains above the diaphragm in continuity. Extended-field radiation therapy by definition is mantle radiotherapy plus radiotherapy to the periaortic nodes to the level of the pelvic rim, usually including the splenic hilar nodes and spleen if the latter has not been removed. Total nodal radiation is radiotherapy encompassing all major lymph node chains from upper cervical to and including inguinal and femoral nodes. The splenic hilar nodes and spleen are again included if the latter has not been removed.
