Chronic lymphocytic leukemia.

[Chronic lymphocytic leukemia]. Presse Med. 2019 Aug 22;: Authors: Jacque N, Leblond V Abstract Chronic lymphocytic leukemia is the most frequent adult leukemia. Eighty per cent of the patients are asymptomatic at diagnosis and 30% of the patients will be never treated. The diagnosis is based on the blood smear examination and immunophenotyping by flow cytometry of blood lymphocytes. The first line option is immunochemotherapy in 90% of the patients without genetic abnormalities associated with chemo resistance. The use of new compounds targeting different pathways is more frequent especially in relapsing patients and could be an alternative to the chemotherapy in the future. Asymptomatic patients with a stable disease assessed by the specialist can be followed by the general practitioner with a blood count and clinical examination every six months or once a year.

Publication date: Available online 12 November 2019Source: Pharmacological ResearchAuthor(s): Zhuojun Liu, Jia Liu, Tianming Zhang, Mingxia Shi, Xiaofang Chen, Yun Chen, Jian YuAbstractReceptor tyrosine kinase-like orphan receptor 1 (ROR1) is an onco-embryonic antigen presented on chronic lymphocytic leukemia (CLL), but not on normal adult tissues, which promotes CLL-cell survival. Here, ROR1 was identified as a new client of Heat Shock Protein 90 (HSP90) via a mass spectrometry-based screen for ROR1-associated partners followed by co-immunoprecipitation (co-IP) analysis. A binding motif (ELHHPNIV) on ROR1 for HSP90 was re...

Contributors : Y Perkarsky ; C M CroceSeries Type : Non-coding RNA profiling by high throughput sequencingOrganism : Homo sapiensWe analyzed small RNA sequencing data from CD5+/CD19+ B cells of a cohort of indolent and aggressive CLL patients compared with CD19+ B-cells of healthy donors.We identified tsRNA signatures in indolent and aggressive CLL vs. normal B-cells; we also found a drastic dysregulation of the expression of mature tRFs in CLL.

ConclusionsThe comprehensive analysis of clinical characteristics, immunophenotypic profiles and cytogenetic features can be helpful in differential diagnosis, especially for patients without an available non-bone marrow biopsy specimen. Universal prognostic factors may help with the early detection of high-risk patients and with stratification in risk-adapted therapy.

AbstractHighly effective treatments for chronic lymphocytic leukemia (CLL) have the potential to reduce significant tumor burden to single cells and therefore require sensitive tools to assess for minimal residual disease (MRD) in bone marrow (BM) biopsies. Flow cytometry (FC) is the current gold standard for detection of MRD, but requires a specialized facility, specific antibody panels, collecting hundreds of thousands-to-millions of cells, and personnel with expertise in the analysis and interpretation of FC MRD data, which may not be feasible in many small laboratories. Dual-antibody immunohistochemistry (DA-IHC) can i...

We report a patient who developed PJP two months after receiving the first course of Lemtrada, and fully recovered after receiving cotrimoxazole treatment. We should remain vigilant of opportunistic infections in patients who develop pneumonitis and evaluate the need for PJP prophylaxis during Lemtrada treatment.

CONCLUSIONS: The clinical roles of PD-1/PD-L1 expression vary between subtypes of lymphoma. Future studies should delineate the prognostic and predictive roles of PD-1 and PD-L1 expression. PMID: 31704289 [PubMed - as supplied by publisher]
