title: Stage IA to IIB mediastinal Hodgkin's disease: three-dimensional volumetric assessment of response to treatment.
abstract: From 1979 to 1986, the response to treatment of 53 patients with stage IA to IIB mediastinal Hodgkin's disease was evaluated by three-dimensional volumetric analysis using thoracic computed tomographic (CT) scans. The mean initial volume of mediastinal disease in 34 patients treated with mantle and para-aortic irradiation was 166 mL, whereas for 19 patients treated with two to six cycles of multiagent chemotherapy and mantle and para-aortic irradiation the mean initial volume was 446 mL. Preliminary data suggested that patients with mediastinal volumes of less than 200 mL had a lower mediastinal relapse rate (13%) than patients with volumes greater than 200 mL (32%). For 12 patients receiving six cycles of nitrogen mustard, vincristine, procarbazine, and prednisone (MOPP), those with a greater than 85% reduction in volume 1 to 2 months after chemotherapy had a lower incidence of mediastinal relapse (zero of six, 0%) compared with patients having 85% or less reduction in volume (four of six, 67%). The primary value of this technique is that it provides a sensitive assessment of response to treatment and may aid in monitoring the effectiveness of a given treatment.
