There is data from the 1950’s to suggest that relapse might be more frequent in women who get pregnant after treatment for Hodgkin Disease. This is a retrospective study using the Swedish healthcare registry. Adult women with Hodgkin’s Disease were followed for relapse and pregnancy. Pregnancy-related relapse was defined as relapse during or within 5 years of pregnancy. They found fewer pregnancy-associated relapses than predicted thereby providing no evidence that pregnancy is a risk factor for relapse of Hodgkin’s Disease.
* Being a registry-based study, there are weaknesses including the fact that some pregnancies may not have been recorded if they occurred out of country or if there was no in-hospital care. However, this study is pretty decent evidence that clinicians should not advise against pregnancy for fear of relapse of Hodgkin Disease.
