Accurate detection of bone marrow involvement in patients with lymphoma is of crucial importance because of the prognostic and therapeutic consequences. Bone marrow trephine biopsy (BMB) is currently regarded as the method of choice for the evaluation of the bone marrow in lymphoma, but it is invasive, has a risk of complications, and lacks sufficient sensitivity due to the possibility of sampl...
1 Bone marrow aspirate and trephine biopsy unless the peripheral blast count is high. 2 Immunophenotyping [CD3, CD7, CD13, CD14, CD33, CD34, CD64, CD117 and cytoplasmic myeloperoxidase (MPO)]. 3 Cytochemistry (MPO or Sudan Black, combined esterase). Can be omitted if four-colour flow cytometry is available. 4 Cytogenetics [with reverse-transcription polymerase chain reaction (RT-PCR) for AML 1-...
I n March 2012, a 31-year-old male patient was diagnosed with alveolar rhabdomyosarcoma (ARMS) manifesting within the left sinus maxillaris with local lymphonodular metastases. No further metastases could be found by positron emission tomography–magnetic resonance imaging. He was treated by neo-adjuvant chemotherapy and consecutive radical endonasal resection and reconstruction in July 2012. In...
Fifty patients were randomised in a double blind placebo controlled study to examine the influence of lorazepam (4 mg orally) before bone marrow aspiration and trephine biopsy. Assessment was made by a visual analogue linear pain scale compiled after the procedure and again 24 hours later. There was no difference in the pain recalled immediately after the procedure between the two groups, but t...
Frozen sections from bone marrow trephine biopsy specimens from children with disseminated neuroblastoma were stained using the monoclonal antibody UJ13A. An immunoalkaline phosphatase technique was the preferred staining method. Acceptable histological detail was obtained from this material and deposits of tumour cells detected. Some apparently fibrous tissue was also stained by this antibody....
