Patterns of care outcome studies. Results of the national practice in Hodgkin's disease.

The outcome of treatment for Hodgkin's disease has been determined for 407 patients treated in 1973. A two-level random sampling assures that these results are representative of the national practice. Actuarial analysis of recurrence-free survival at four years is: Stage IA, 80%; Stage IIA, 75%; Stage IIIA, 60%; combined Stages IB, IIB, and IIIB, 50%. Factors significantly associated with recurrence include stage, histology, age, chemotherapy, new patient load, part-time practice, treatment technique, treatment machine, treatment simulation, work up score, treatment score, and facility of treatment. Major treatment complications by stage ranged from 4-12%; complications are significantly associated with disease location, patient age, and the presence of coexisting disease.
