Uterine relapse of Philadelphia chromosome-negative acute lymphoblastic leukemia.

We report such a patient who developed relapse in the bone marrow and uterus. The uterine lesion, which presented as abnormal uterine bleeding, consisted of a mass on MRI and proliferation of ALL cells on histology. MRI revealed a heterogeneous high-intensity mass (T2-WI/D-WI) with a diameter of 6.8 cm, a notable decrease in the apparent diffusion coefficient (ADC), and mild enhancement by contrast enhancement study. Histological findings of the uterine cervix demonstrated the infiltration of ALL. The patient achieved remission by allogeneic haplo-identical hematopoietic stem-cell transplantation, but died of complications of the transplantation. This case suggested that attention should be paid to the uterus as a site of extramedullary relapse. In addition, abnormal uterine bleeding, which is a common sign of hormonal imbalance and hormone replacement therapy after chemotherapy, may be an initial sign of extramedullary recurrence. To confirm uterine relapse as an intractable disease, the accumulation of more cases is required. PMID: 32981913 [PubMed - in process]

In this study, we present a case of ALL who was diagnosed with CCHF simultaneously. A 43-year old female patient who works in the library and does not have a chronic disease other than asthma and thyroid disorder, has admitted to our hospital with the complaints of intermittent fever, weakness, generalized joint and body pain for about 3 weeks. She had fever and the physical examination revealed bilateral cervical and right postauricular lymphadenopathies. Her aspartate aminotransferase: 77 U/L, alanine aminotransferase: 117 U/L, lactate dehydrogenase: 616 U/L, hemoglobin: 8.27 g/dl, leukocyte count: 15.690/mm3 , neutrophi...

Discussion Pediatric cancers in the US number about 12,000 per year. After injury, it is the second leading cause of death in children and adolescents. Cancer presentations vary widely, but often begin with non-specific symptoms that continue or progress depending on the location and tumor type. Patients can present with oncological emergencies especially if there are mechanical obstruction such as superior vena cava syndrome or cerebral herniation. More commonly are infections due to immunosuppression. Cancer treatment also causes its own myriad of problems that clinicians need to be aware of to diagnosis and treat, but a...

Michele Callea Acute myeloid leukemia (AML) is a heterogeneous group of diseases, whose classification is based on lineage-commitment and genetics. Although rare in childhood, it is the most common type of acute leukemia in adults, accounting for 80% of all cases in this age group. The prognosis of this disease remains poor (especially in childhood, as compared to acute lymphoblastic leukemia); however, overall survival has significantly improved over the past 30 years. The health of the oral cavity is a remarkable reflection of the systemic status of an individual. Identification of the signs and symptoms of oral le...

Authors: Di Paola J, Fisher MH Abstract We and others recently described families with germline heterozygote mutations in ETV6 leading to autosomal dominant highly penetrant thrombocytopenia, red cell macrocytosis and predisposition to leukemia.The bone marrow of affected individuals shows erythroid dysplasia and hyperplasia of small, hypolobulated immature megakaryocytes suggesting a differentiation arrest. This discovery led to subsequent studies that confirmed our findings and to additional larger studies that demonstrated a 1% frequency of germline ETV6 mutations among 4405 individuals with acute lymphoblastic ...

Ataxia-telangiectasia (AT) is a hereditary recessive autosomal disorder following a course of progressive cerebellar ataxia, and oculocutaneous telangiectasia. Disease-specific telangiectasias are generally localized in the oculocutaneous region, while telangiectasias located within the bladder are rarely seen in patients with AT. The patient who had been followed-up with a diagnosis of AT since the age of 3 years was later diagnosed with acute lymphoblastic leukemia at the age of 8 years. The patient developed hematuria approximately in the 29th month of treatment. The cystoscopy revealed regions of extensive hemorrhagic ...

Granuloma in marrow with lurking "Leuk": Two happenstances. Indian J Pathol Microbiol. 2020 Apr-Jun;63(2):315-318 Authors: Sreeram S, Basavaiah SH, Murali N, Balanthimogru P Abstract Granulomas are described very rarely in marrow biopsies. They have hardly been reported in association with acute lymphoblastic leukemia. We herein report two cases of ALL associated with granulomas each at different stage of their clinical course that led to a diagnostic and therapeutic dilemma. First case was of a 42-year-old woman diagnosed with tuberculosis who presented with bleeding gums during anti-tuberc...

The following day, mice received 1,000,000-3,000,000 primary blasts derived from the peripheral blood of patients with ALL. Mice were monitored for engraftment for ~10-13 weeks via tail vein bleeding for engraftment. Some mice received high dose CAR-T cell therapy and an isotype control antibody treatment.

Authors: Patel SH, Vasu S, Guo L, Lemaster O, Byrd JC, Walker A Abstract Acute undifferentiated leukemia (AUL) is a subtype of acute leukemias of ambiguous lineage. There is no standard treatment approach for AUL, although acute lymphoblastic leukemia-like regimens for induction therapy have been used. Additional data suggest that AUL may be better treated as acute myeloid leukemia (AML), given their similarities in genetic, cytogenetic, and gene expression patterns. Somatic mutations of IDH1 are found in 7% to 14% of patients with AML; however, the patient in this study was the first patient with IDH1-mutated AUL ...

GeyerAbstractOlder adults with acute lymphoblastic leukemia (ALL) continue to have a poor prognosis, in part due to greater chemotherapy-related toxicities. We herein report a 67-year-old man with Philadelphia chromosome (Ph)-negative B-cell ALL, who exhibited refractoriness to 3 different regimens of induction chemotherapy and experienced multiple complications including intracranial bleeding and respiratory failure, who achieved minimal residual disease (MRD)-negative complete response (CR) af...

;o LR Abstract Thromboembolism (TE) is a well-recognized complication of pediatric cancer and can lead to mortality and excess morbidity. There is conflicting evidence about the effectiveness and safety of thromboprophylaxis in children. We conducted a systematic literature review and network meta-analysis of primary pharmacological thromboprophylaxis in children and adolescents (0-21 years) with cancer. The primary outcomes were objectively proven TE and major bleeding. The network meta-analysis included comparisons of multiple alternatives simultaneously: antithrombin (AT) replacement, low molecular weight hepar...
