Serum Estrogen and its Soluble Receptor Levels in Egyptian Patients with Chronic Myeloid Leukemia: A Case–Control Study

A new case of trisomy 5 with complex karyotype abnormalities in B-cell prolymphocytic leukemia: a case study

Background

The B-cell prolymphocytic leukemia (B-PLL) diagnosis is challenging due to the superposition with mature B-cell leukemia and/or lymphoma.

Objective

An insight case study of trisomy 5 with complex karyotype abnormalities in B-cell prolymphocytic leukemia.

Subject and methods

A 72-year-old man was referred to the Hematology Department, Qilu Hospital, Shandong University, because of persistent fever (10 days) and lymphocytosis. A detailed diagnostic methods including complete blood count, bone marrow aspiration, flow cytometry, conventional karyotype analysis, fluorescence in situ hybridization (FISH), quantitative real-time polymerase chain reaction (qRT-PCR), next-generation sequencing technology (NGS) used to detect 41 kinds of mutant genes related to hematological malignancies were conducted and reasonable therapeutic regimens including emergent leukapheresis accompanied by basification of urine and hydrotherapy, followed by a regimen of cyclophosphamide and dexamethasone.

Results

Subject white blood cell count was 143.43 × 109/L, and 56% prolymphocytes. He did not show lymphadenopathy but splenomegaly. Immunophenotyping of prolymphocytes was CD5(+low), CD10(−), CD11c(−), CD19(+), CD20(+), cCD22(+), CD23(−), cCD79a(+), CD79b(+), FMC7(±), CD43(−), CD3(−), CD56(−), CD103(−), HLA-DR(+), and Lambda(+). R-banding and FISH revealed that leukemia cells carried extra chromosome 5. Considering the rare occurrence of trisomy 5 found in prolymphocytic leukemia, especially in Asians, with rapid disease progression. We know that median survival of B-PLL is three years after diagnosis, while survival time of this patient was only 1 month.

Conclusion

This study could provide the firsthand materials for precision, medicine and mechanism research in cytogenetics and molecular biology. It inferred that trisomy 5 might be a poor prognosis indicator, providing directions for clinical practice in the foreseeable future.

Serum estrogen and its soluble receptor levels in Egyptian patients with acute leukemia: case-control study

Background

Acute leukemias are malignant neoplastic diseases that arise from either lymphoid [ALL] or myeloid [AML] cell lines that are distinguished by the proliferation of BM non-functional immature cells and subsequently released into the bloodstream. ALL is prevalent malignancy in young, while AML in older. Diagnosis is usually routinely performed through peripheral blood count and smear then confirmed by BM aspirate. It is remarkable to notice that leukemia can be manifested at high, low, and even at normal leucocyte count. While treatment results have improved steadily over the last decades in younger and adults, limited changes have been in survival among subjects of age > 60 years. Aim of the work is to measure the serum estrogen [E2] and its soluble receptor [ER] levels in acute leukemia patients and extrapolate its possible clinical significance. This study included 40 [20 females and 20 males] healthy volunteers clinically free from any disease, 40 [20 females and 20 males] AML patients, and 40 [20 females and 20 males] ALL. To all subjects, serum E2 and its soluble ER level were investigated by ELISA.

Results

Serum E2 [pg/ml] level was lower in AML and ALL female and male patients groups than control group. Serum ER [ng/ml] level was lower in AML and ALL female and male patients groups than control group.

Conclusion

Estimation of serum E2 and its soluble ER level is of edifying diagnostic value. Determination of serum E2 and its soluble ER level in AML and ALL patients is of value in deciding treatment therapeutic target protocol.
