Is chronic lymphocytic leukemia a contraindication for radon and thermotherapy?--a case report.

A growing number of patients presenting for radon-thermotherapy have a history of malignant disease. The question as to whether malignancies in general are a contraindication for radon treatment or mild hyperthermia during spa therapy is still a subject of controversy. We report a patient with osteoarthritis and a frozen shoulder who repeatedly underwent speleotherapeutic radon and hyperthermia treatment in the gallery of the Gasteiner Heilstollen, Austria, despite concomitant chronic lymphocytic leukemia (B-CLL, Rai stage 0). After nine courses of radon-thermotherapy over eight years, no apparent negative impact on CLL was noted. The purpose of this case report is to encourage discussion as to whether CLL or other past or present malignancies must be considered a contraindication for spa treatment such as radon-thermotherapy.
