Positron emission tomography-computed tomography (PET-CT) scanning has been shown to be more sensitive than bone marrow biopsy (BMB) in detecting bone marrow involvement (BMI) in classical Hodgkin lymphoma (cHL). In this 5-year retrospective series, 93 (54%) of all new cases of cHL were staged using PET-CT and BMB. PET-CT identified focal bone marrow uptake in 17/93 (18.3%), whilst only five of these (29.4%) were confirmed by BMB. Abnormal pelvic uptake was seen on PET-CT in these five cases. The other 12 cases were missed, giving BMB a sensitivity of 29.4% and a specificity of 100%. PET-CT upstaged 9.7% of patients compared to CT alone. BMB upstaged only one patient; however, this patient was already stage IV on PET-CT. BMB did not alter clinical management in any case. Bone positivity on PET-CT appeared to correlate with anemia, raised lactate dehydrogenase (LDH) and B symptoms. BMB has little or nothing to offer staging cHL in the PET-CT era. © 2014 Informa UK, Ltd.
