Bone marrow examination: for metastatic tumor: aspirate and biopsy.

A 6-year experience with bone marrow aspirates and biopsies (96 cases) positive for metastatic carcinoma is reviewed. Marrow examination detected secondary carcinoma in 58 cases (60%) despite negative roentgenographic and/or bone scan examinations. Breast carcinoma was the most frequent primary site. The bone marrow biopsy was superior to the aspirate in finding carcinoma (97% vs. 72%). However, in an occasional case, tumor was found only in aspirate preparations. Both procedures should be considered complementary and are recommended in the marrow evaluation of patients with carcinoma.

Bone marrow examination at a paediatric hospital in Kenya.

OBJECTIVE: To investigate the main indications for, and common conditions found in bone marrow examinations (BME) of children. METHODS: This was a retrospective study from September 1, 1993 to September 3 1998. All bone marrow aspirate and trephine biopsy results were retrieved. The clinical data provided by clinicians were also noted. RESULTS: A total of 97 BME were recorded from patients aged two months to 13 years. The peak ages for BME were six to eight years (24% of patients). The more frequent indications for BME were unexplained anaemia found in 26% request forms, investigation for solid tumours (10%) and lymphoma (10%) and remission assessment after treatment for leukaemia (26%). The main findings were malignancy (27%) with leukaemia being commonest (ALL) 16% of patients and acute myeloblastic leukaemia (5%). Haematinic deficiency was seen in 12.7% of cases with iron deficiency being the commonest. There were some notable differences and similarities in the study as compared to a similar one performed at a local referral hospital. CONCLUSION: The importance of BME as a crucial investigational tool in the management of patients is underscored. Interpretation is more meaningful when the haematologist has adequate clinical data.

Pattern of haematological diseases diagnosed by bone marrow examination in Yemen: a developing country experience.

There is lack of information about the relative prevalence of haematological disorders in Yemen and other Middle East countries. The aim of this study was to evaluate the pattern of haematological diseases diagnosed by bone marrow examination in Yemen considering the limited diagnostic facilities. At the referral haematology centre in Yemen, between November 1999 and November 2005, 785 patients >14 years old were evaluated by bone marrow examination. Relevant investigations were performed when needed. A total of 627 patients had haematological disorders other than lymphoma, and their data were analysed. There were 273 females and 354 males. A total of 159 patients had Acute myeloid leukaemia, 75 had acute lymphocytic leukaemia, 87 had chronic myeloid leukaemia, 36 chronic lymphocytic leukaemia, eight had multiple myeloma, 13 myelodysplastic syndromes, seven myelofibrosis, seven polycythaemia vera, three primary thrombocythaemia, two hairy cell leukaemia, two metastases, 36 aplastic anaemia, 29 immune thrombocytopenic purpura (ITP), nine autoimmune haemolytic anaemia, three pernicious anaemia, 65 iron deficiency anaemia, 57 megaloblastic anaemia and malaria, 18 mixed deficiencies, and 11 patients had visceral leishmaniasis. Sex- and age-related distribution of the various disorders was also presented. In conclusion, the leukaemias were the most frequently encountered diagnosis followed by iron deficiency anaemia, megaloblastic anaemia and malaria, aplastic anaemia and ITP respectively. The other haematological disorders were less common. These findings are comparable with that seen in other developing and developed countries.

[Usefulness of bone marrow examination in patients with advanced HIV infection].

A bone marrow investigation is a common examination in HIV infected patients for the study of cytopenia, febrile syndromes of unknown origin and extension of neoplastic disorders. A study was made of bone marrow specimens from 35 patients with advanced HIV infection (stage IC or C, CDC, Atlanta) for morphologic and culture investigations (aerobes, anaerobes, fungi, and mycobacteria). In nine patients cytopenia accounted for the investigation of bone marrow specimens (9 aspirates and 3 biopsies); in only two cases did the investigation orientate towards a possible etiology: in the first patient a parvovirus B19 infection and in the second patient a hemophagocytic syndrome. In twenty-five patients the bone marrow specimen was studied because of fever of unknown origin (23 aspirates and 10 biopsies) and only in one case was the identification of Mycobacterium tuberculosis obtained. The other patient was studied for lymphoma staging and aspirate and biopsy examinations were normal. A high percentage of patients had eosinophilia, plasmacytosis, increased iron reserves, fibrosis, and changes consistent with myelodysplasia. In conclusion, in our experience the investigation of bone marrow specimen was of little help to clarify the possible etiology of cytopenia and febrile syndromes of unknown origin in patients with advanced HIV infection.

Bone marrow examination in small cell carcinoma of the lung. Comparison of trephine biopsy with aspiration.

Bone marrow examinations in 146 patients with small cell carcinoma of the lung were reviewed. The results of trephine biopsy and aspiration were compared in 128 patients in whom both techniques were performed. Twenty-seven of the 128 examinations (21.2%) showed positive aspirates and 30 biopsies (23.4%) revealed metastatic disease. The overall agreement between the aspirates and biopsies was 96.1%. Thirty-one patients (24.2%) had metastatic tumor in either aspirate or biopsy: 4 of these (12.9%) had a positive biopsy with negative aspirate, and 1 (3.2%) showed a positive aspirate and negative biopsy. The Jamshidi needle was used, yielding an average of 4.1 cm of core material per biopsy. The authors conclude that bone marrow biopsy using the Jamshidi needle is equivalent to aspiration. Although both procedures are complementary, a satisfactory specimen obtained with the Jamshidi needle alone may yield nearly equal detection to the combined procedures. Some guidelines for obtaining an optimal biopsy specimen are suggested.

Usefulness of bone marrow examination in the evaluation of unexplained fevers in patients infected with human immunodeficiency virus.

The diagnostic usefulness of 69 bone marrow examinations (BMEs) performed for evaluating unexplained fever in 65 persons who were infected with human immunodeficiency virus was retrospectively compared with the usefulness of other diagnostic modalities used to investigate the cause of fever. An etiology for the fever was identified by BME in 22 of the 69 cases (diagnostic yield, 32%). In 19 of these 22 cases, the same diagnosis had been made by another diagnostic modality, but the diagnosis was made by BME as rapidly or sooner in 10 of the 19 cases and was made exclusively by BME in the three other cases. We suggest that BME is indicated when a diagnosis is urgently sought or when an evaluation with other diagnostic modalities has been unsuccessful.

Zinc-induced copper deficiency: a report of three cases initially recognized on bone marrow examination.

Copper deficiency is a rare cause of sideroblastic anemia and neutropenia that often is not suspected clinically. The morphologic findings in bone marrow, while not pathognomonic, are sufficiently characteristic to suggest the diagnosis, leading to further testing to establish the correct diagnosis. Excess zinc ingestion is among the causes of copper deficiency. We present 3 cases of zinc-induced copper deficiency in which the diagnosis first was suggested on the basis of bone marrow examination. The first patient was a 47-year-old man with a debilitating peripheral neuropathy that had progressed during the previous 18 months, mild anemia, and severe neutropenia. The second was a 21-year-old man receiving zinc supplementation for acrodermatitis enteropathica in whom moderate normocytic anemia and neutropenia developed. The third patient was a 42-year-old man with anemia, severe neutropenia, and a peripheral neuropathy that had progressed during 8 months. The bone marrow findings in all cases suggested copper deficiency, which was confirmed by further laboratory testing and determined to be due to zinc excess. The morphologic features, clinical manifestations, differential diagnosis, and pathogenetic mechanisms are discussed.

Routine bone marrow examination in the management of acute lymphoblastic leukaemia of childhood.

Eighty-four children with acute lymphoblastic leukaemia (ALL) who had relapsed in bone marrow were studied to assess whether treatment would be more successful if relapse was detected before the disease became clinically evident. Patients whose relapse was detected by routine bone marrow examination before the disease became apparent were compared with those whose relapse was suspected from clinical examination or peripheral blood findings. In the former there was a lower percentage of blast cells in the marrow (p less than 0.02) and the patients suffered less from complications of the disease, but there was no difference in the incidence or duration of second remissions between the two groups.

Bone marrow examination: techniques and interpretation.

Proper evaluation of the bone marrow requires adequate sampling, appropriate specimen processing, sufficient clinical history, and review of representative blood smears and pertinent laboratory data. Aspiration and needle biopsy should be performed at the same time routinely. Aspirate smears, touch preparations from the biopsy, and sections from the aspirate and biopsy should be processed appropriately and examined in a systematic fashion to perform a comprehensive evaluation considered essential to arrive at or rule out a diagnosis, or as an adjunct in the management of patients, particularly those undergoing chemotherapy and/or radiotherapy.

Pathology and biology guidelines for resectable and unresectable neuroblastic tumors and bone marrow examination guidelines.

The recommendations concerning tumor and bone marrow handling for the evaluation of molecular-biologic and molecular-genetic and immunologic markers presented in this paper were developed by the SIOP Europe Neuroblastoma Pathology and Biology and Bone Marrow Group. Although the Guidelines were developed for neuroblastic tumors (neuroblastoma, ganglioneuroblastoma and ganglioneuroma), they are applicable to all other tumor entities as well. The paper is subdivided in three main parts. The Pathology Guidelines give an overview about the handling, sectioning and securing of tumor material in case of resectable and non-resectable neuroblastic tumors. The Guidelines encompass open biopsies, tru cut biopsies, fine needle aspirations, and bone marrow aspiration. The importance of the pathologic evaluation for the interpretation of the molecular-genetic and molecular-biologic results, which also includes the exact determination of the tumor cell content is stressed. Besides this, recommendations concerning tumor material obtained after cytotoxic therapy, immunohistologic and immuno-cytologic issues and lymph node examination are addressed. In the Biology Guidelines, the different methods for MYCN, chromosome 1p36 investigations and DNA content measurements are discussed and DNA probes are recommended. Furthermore, specified definitions and a common terminology already used in the SIOP Europe Neuroblastoma Group are presented. In the Bone Marrow Guidelines, recommendations concerning the methods to be employed are given and the most important pitfalls are demonstrated. Both the use of standardized methods and the application of a common language will, it is hoped, contribute to the quality and reliability of collected data and thus to a better comparability between and among research reports. These improvements should prove to be of great value for the affected patients.

Bone marrow examination in patients with AIDS and AIDS-related complex (ARC). Morphologic and in situ hybridization studies.

Bone marrow examinations were performed on 20 patients with acquired immune deficiency syndrome (AIDS) and 39 with AIDS-related complex (ARC). Fever of unknown origin and thrombocytopenia were common in ARC, but anemia and leukopenia were most frequent in AIDS. Changes in stromal cells and perivascular cuffing of plasma cells were found significantly more often in patients with AIDS than in those with ARC. Malignancies were common in both groups. Human immunodeficiency virus (HIV) nucleic acids were detected with the use of a 3H-labeled cDNA probe with an in situ hybridization method in 11 bone marrow samples (three ARC and eight AIDS). Most commonly positive cells were mononucleated, resembling lymphocytes and histiocytes. Endothelial cells, interdigitating reticulum cells, nucleated red blood cells, and immature myeloid cells also had positive results in some instances. The number of HIV-positive cells was not related to the size of the bone biopsies or the clinical diagnoses. The authors postulate that changes in the peripheral blood and bone marrow of these patients may be related to latent persistent infection with HIV.

Is bone marrow examination in small-cell lung cancer really necessary?

Of 403 patients with small-cell lung cancer, we identified by aspiration, biopsy, or both 67 with bone marrow involvement and found the two procedures to be complementary in detecting marrow involvement. The mean surface area of the positive biopsy specimens was significantly greater than that of a randomly selected group of negative biopsy specimens, suggesting that the larger the specimen, the greater the chance of detecting tumour. Patients with marrow involvement had only a slightly worse prognosis compared with other patients who had extensive disease. Only 7 of the 403 patients (1.7%) had extensive disease based on marrow involvement alone. Because bone marrow examination rarely changes the stage of cancer in noninvasively assessed patients, and has no impact on the tolerance of chemotherapy and only a small effect on length of survival, we do not recommend this procedure in the routine staging of small-cell lung cancer.
