Hybrid acute leukaemia--a report of 3 cases

Ng SC, Wong TK, Lin HP

Ann Acad Med Singap, 1989 Nov;18(6):721-3.

PMID: 2624424

The simultaneous expression of both lymphoid and myeloid phenotypic features in acute leukaemia is rare. We report 3 cases of biphenotypic hybrid acute leukaemia seen in our institution. All 3 patients achieved remission with treatment for acute lymphoblastic leukaemia but two subsequently relapsed while on treatment. The hybrid acute leukaemias are important areas for further research both for delineation of basic biology and choice of optimal treatment.

A case of childhood hepatitis B virus infection related primary hepatocellular carcinoma with short malignant transformation time

Cheah PL, Looi LM, Lin HP, Yap SF

Pathology, 1991 Jan;23(1):66-8.

PMID: 1648195

A case of primary hepatocellular carcinoma (PHC) developing in a 10 year old boy who contracted Hepatitis B virus (HBV) infection in the course of maintenance phase chemotherapy for acute lymphoblastic leukemia was seen at University Hospital, Kuala Lumpur. This case is of interest in that it (1) supports an etiological relationship between HBV infection and PHC, (2) manifested a distinctly short malignant transformation time, and (3) draws attention to the possible contributory role of chemotherapy in increasing the risk of developing PHC.

PMID: 1823093

Immunophenotyping of acute leukaemias has become an important diagnostic tool in haematology laboratories as it is now well recognised that the presence of certain surface markers has prognostic significance. In 1988, we experimented with the alkaline phosphatase anti-alkaline phosphatase (APAAP) method for immunophenotyping of leukaemic cells in our laboratory. 48 cases of peroxidase-negative acute leukaemias were studied. Our study showed that 2 peroxidase-negative cases carried myeloid surface markers, 44% were negative for the markers studied and 5% were unclassified due to technical problems. We concluded that the APAAP method is a useful technique for demonstrating cell markers in leukaemic cells as the reaction is reddish and usually intense. We failed to demonstrate surface markers in 44% of the cases probably because of the choice of a limited panel of monoclonal antibodies.

Biphenotypic hybrid acute leukaemia detected by two colour flow cytometry

Gudum HR, Chin YM, Menaka N, Jeyaranee S, Lin HP, Tay A

Malays J Pathol, 1992 Jun;14(1):25-8.

PMID: 1469914

Immunophenotypic studies using immunofluorescent flow cytometry were performed on the blast cells of 36 patients with acute leukaemia using a panel of eight monoclonal antibodies. Six patients had blasts which co-expressed markers for lymphoid and myeloid differentiation, and which were therefore defined as biphenotypic hybrid acute leukaemia. Of the six, three patients were in the paediatric age group (below 12 years old) while the other three were more than 12 years old. Peripheral blood counts were variable; however, bone marrow infiltration was extensive (blasts > or = 75% in all). At the time of study, remission was achieved in only two patients. The authors' data show that biphenotypic hybrid acute leukaemia is not rare in Malaysia. This represents a subgroup of acute leukaemia identifiable by immunophenotyping but not by the French-American-British classification based on morphological and basic cytochemical studies alone. The recognition of this subgroup is important for both practical and theoretical reasons. There are implications for treatment of the individual patient because treatment directed at a single lineage may not be effective. The two colour flow cytometry proved to be a useful tool for diagnosis and classification of acute leukaemia.

Fulltext Breakpoint cluster region (BCR) gene rearrangement studies in chronic myeloid and acute lymphoblastic leukemias

Chin YM, Bosco JJ, Koh CL

Med J Malaysia, 1992 Jun;47(2):110-3.

PMID: 1494330

Deoxyribonucleic acid (DNA) of twenty chronic myeloid leukemia (CML) and thirty acute lymphoblastic leukemia (ALL) patients were analysed by Southern hybridization. The DNA was digested with BglII and hybridized with a 4.5-kilobase (kb) ph1/bcr-3 DNA probe. All the 20 CML patients showed gene rearrangement within a 5.8-kb segment (the major breakpoint cluster region, M-bcr) of the breakpoint cluster region (bcr) gene of chromosome 22, indicating the presence of the Philadelphia chromosome. M-bcr rearrangement at the bcr gene of chromosome twenty-two was not detected in all the thirty ALL patients (nine adults and twenty-one children) and two normal controls.

Ho CM, Khuzaiah R, Yasmin AM

Med J Malaysia, 1994 Mar;49(1):29-35.

PMID: 8057987

Primary varicella-zoster virus infection in children with haematological malignancy is a life threatening disease. In one year, there were 10 cases of varicella and 2 cases of zoster among these children as well as 5 mothers who were accompanying their children who developed varicella in the oncology ward. Two children died of fulminating disease despite aggressive antiviral and supportive treatment. Acyclovir can be used in treatment and prophylaxis in exposed susceptible children. Varicella -zoster immune globulin is not available in this country. Vaccination with live virus has been shown to be protective in immunocompromised children and needs consideration.

A six-year-old boy, a known case of acute lymphoblastic leukaemia (ALL) on remission since 1991 presented with leukocoria and poor vision of the left eye for two days' duration. Examination revealed endophthalmitis in the left eye with raised intraocular pressure. Anterior chamber paracentesis with vitreous biopsy confirmed a diagnosis of ocular involvement. Further investigation revealed that he also had bone marrow and central nervous system relapse. Clinical manifestation and treatment modalities of ocular involvement in leukaemia are discussed.

Intensive chemotherapy has prolonged survival in cancer patients. Unfortunately it has also predisposed them to unusual infections because of their immunocompromised state. We report a case of fungal septicaemia caused by Geotrichum candidum, an imperfect yeast of low virulence in a young girl with acute lymphoblastic leukaemia. It was successfully treated with amphotericin B. The morphological characteristics of this fungus leading to its identification are described.

Outcome of treatment in adult acute lymphoblastic leukaemia in an Asian population: comparison with previous multicentre German study

Bosco I, Teh A

Leukemia, 1995 Jun;9(6):951-4.

PMID: 7596183

Reports on the outcome of treatment in ALL in Asian (non-Caucasian) adults have been few, and published results compare very unfavourably with results of treatment from 'Western' centres. Seventy-four newly diagnosed Malaysian patients with ALL between the ages of 15 and 69 were treated from 1986 to 1990. The clinical features and prognostic factors were similar to those reported in 'Western' series. The chemotherapy protocol utilized was adapted from the one used by Hoelzer et al in the multicentre German study. The complete remission rate was 73%. The probability of continuous complete remission at 5 years was 29% with a median duration of remission of 15 months. This compares with Hoelzer's initial results of 77% CR rate and 35% CCR at 5 years. Patients with an initial white cell count of less than 30 x 10(9)/l at presentation were found to have a significantly better disease-free survival than those with a count of more than 30 x 10(9)/l (35 vs 22%, P = 0.026, univariate analysis). There was no difference in leukaemia-free survival according to age, sex, ethnic group, or immunophenotype. These results show that the use of moderately intensive chemotherapy protocols in Asian (non-Caucasian) patients achieves similar results to those used in Caucasians. We also showed that the difficulties in 'curing' approximately 70% of adult patient with ALL are universal.

Fulltext Concordant childhood acute lymphoblastic leukemia in monozygotic twins

Chin YM, Wan Ariffin A, Lin HP, Chan YS

Med J Malaysia, 1996 Mar;51(1):145-8.

PMID: 10967997

Two 4-year-old monozygotic Chinese, female twins developed concordant childhood acute lymphoblastic leukemia (ALL) within an interval of about 2 weeks. Based on morphology and cytochemistry findings of the bone marrow blast cells, a diagnosis of ALL, L1 was made. Immunophenotyping showed the blast cells of both twins expressed similar antigens, i.e. HLA-DR, CD10, CD13, CD19, CD22 and CD34. Identical blood group, same HLA (human leucocyte antigen) genotype, sex and similar appearance suggest that the twins are monozygotic. Since the bone marrow leukemic cells of both twins were identical in morphology and expressed the same antigens with almost similar percentages of positivity, it is likely that the blast cells were derived from the same single clone. Based on the single clone hypothesis, the leukemogenic event must have arisen in utero in one twin and the cells from the abnormal clone then spread to the other twin via shared placental anastomoses.

Fulltext Second malignant neoplasms: an increasingly recognized complication of childhood cancer

Ariffin H, Ariffin WA, Chan LL, Lam SK, Lin HP

Med J Malaysia, 1997 Jun;52(2):174-7.

PMID: 10968078

Second malignant neoplasms (SMN) are an increasingly recognized late complication seen in childhood cancer survivors. A total of 3 cases of SMN have been found in the Department of Paediatrics, University Hospital Kuala Lumpur after a 15-year experience of treating childhood malignancies. Two cases are described here. The first developed abdominal non-Hodgkin's lymphoma 3 years after undergoing an allogeneic bone marrow transplant for second relapse of acute lymphoblastic leukaemia, while the second child developed myeloid leukaemia two years after completing treatment for acute lymphoblastic leukaemia. Progress in the management of childhood cancer in Malaysia and the availability of bone marrow transplantation facilities have increased the number of childhood cancer survivors; leading to increased incidence of SMN.

Macular haemorrhage in adult acute leukaemia patients at presentation and the risk of subsequent intracranial haemorrhage

Jackson N, Reddy SC, Harun MH, Quah SH, Low HC

Br J Haematol, 1997 Jul;98(1):204-9.

PMID: 9233585

Retinal changes are common in adult acute leukaemia patients at presentation, but whether they correlate with the risk of subsequent intracranial haemorrhage is unknown. A 4-year study has been carried out in 82 newly-diagnosed acute leukaemia patients, aged 12-77 years, who were studied prospectively for the presence of intra-retinal haemorrhages (IRH), white-centred haemorrhages (WCH), cotton-wool spots (CWS) and macular haemorrhages (MH). Groups with and without these features were compared for their risk of intra-cranial haemorrhage (ICH) within the first 30 d following diagnosis. There was no association between the incidence of ICH and the presence of IRH, WCH or CWS. However, 6/13 of those with MH developed ICH, compared to 6/69 of those without MH (relative risk 5.0, CI 95% [2.03-12.33], P=0.003). The only other identifiable risk factor for ICH was the M3 subtype of AML, but if the four cases of M3-AML were discounted from analysis, MH remained a highly significant risk factor for ICH. Patients with MH should be monitored intensively for the development of ICH, and receive priority in the allocation of platelets where these are in short supply.

Extra-nodal non-Hodgkin's lymphoma (NHL) of the pinna has only been reported once in a patient with immunodeficiency. We report an unusual case of lymphoblastic lymphoma in a patient without any immunodeficiency, presenting as an inflammatory lesion of the pinna, which illustrates the need to biopsy any non-healing lesion as soon as possible to ensure that such a treatable malignancy is diagnosed at an early stage.

A prospective study of ocular manifestations in childhood acute leukaemia

Reddy SC, Menon BS

Acta Ophthalmol Scand, 1998 Dec;76(6):700-3.

PMID: 9881556

PURPOSE: To determine the prevalence of ocular manifestations in childhood acute leukaemia at the time of presentation.

METHODS: Eighty-two children with acute leukaemia were examined for ocular lesions within two days of diagnosis before starting chemotherapy. The detailed ocular examination of both eyes was carried out by the ophthalmologist irrespective of the presence or absence of eye symptoms in all cases.

RESULTS: Only 3 out of 82 children presented with eye symptoms (3.6%). However, ocular changes were found in 14 children (17%); ten with lymphoblastic and four with myeloid leukaemia. The ocular lesions observed were proptosis, intraretinal haemorrhages, white centered haemorrhages, cotton wool spots, macular haemorrhage, subhyaloid haemorrhage, vitreous haemorrhage, papilloedema, cortical blindness, sixth nerve palsy, and exudative retinal detachment with choroidal infiltration.

CONCLUSION: In view of the high prevalence of asymptomatic ocular lesions in childhood acute leukaemia, routine ophthalmic examination should be included as a part of evaluation at the time of diagnosis.

Immunophenotyping pediatric leukemias in Kelantan, Malaysia

Menon BS, Dasgupta A, Jackson N

Pediatr Hematol Oncol, 1998 Mar-Apr;15(2):175-8.

PMID: 9592844

This study reviewed the immunophenotyping results of children with acute leukemia in Kelantan, Malaysia. In the 3.5-year period (January 1994 to June 1997), 45 cases were identified. All children were under the age of 12 years and the predominant ethnic group was Malay. Thirty-six cases (80%) were acute lymphoblastic leukemia (ALL) and 9 cases (20%) were acute myeloblastic leukemia (AML). Of the ALL cases, 3% were of B-cell and 22% of T-cell origin, and 96% of the B-lineage ALL were CD10 positive. All the AML cases expressed CD33 and 78% were positive for CD13. The incidence of mixed-lineage leukemias was 13.8% for My+ ALL and 11.1% for Ly+ AML.
