Background
  • In Hodgkin's Disease(HD) bone marrow involvement(BMI) has been reported as a unfavorable prognostic factor. Accordingly, bone marrow biopsy(BMB) is frequently used in staging of disease.
  • Increasingly, the utility of this procedure in early stage disease(Stage IA & IIA)has been questioned.
  • In this study the authors try to identify factors that predict for BMI, so that those patients at low risk can avoid BMB as a part of staging.
Materials and Methods
  • From 1982-2000, 1161 HD patients underwent BMB as a part of their staging.
  • Median age was 37 years old
  • 19% had bulky disease
  • 39% had B symptoms
  • 57% were male
  • 56% had supra-diaphragmatic involvement, 9% infra-diaphragmatic disease, and 35% with both
  • 59% had nodular sclerosis histology, 30% mixed cellularity, and 4% lymphocyte depleted
  • 946 patient cases underwent multivariate analysis in an attempt to identify factors related to BMI.
Results

Five main independent variables were identified that predicted for positive BMI:

  1. B symptoms
  2. infra-diaphragmatic involvement
  3. mixed cellularity or lymphocyte depleted histology
  4. more than 3 involved sites
  5. liver involvement.
Author's Conclusions
  • Predictive models based on these clinical factors could be formulated to
  • help identify those patients with a low risk of BMI, and thus avoid BMB in
  • these patients.
Clinical/Scientific Implications
  • Bone marrow biopsy is not a simple risk free procedure.
  • It can be very painful and anxiety provoking for the patient as well as be a potential source of serious infection.
  • Identifying those patients at very low risk for bone marrow involvemnt would help reduce the number of unecessary procedures in the staging of Hodgkin's Disease.

ASH: Hodgkin's Lymphoma Tx Shows Promise in Small Trial

Dec 9, 2014 - In a small new trial, a form of treatment based on the body's immune system appears to be helping patients with Hodgkin's lymphoma for whom other treatments have failed. The study was published online Dec. 6 in the New England Journal of Medicine to coincide with its expected presentation on Saturday at the annual meeting of the American Society of Hematology, held from Dec. 6 to 9 in San Francisco.
