Dramatic Response with Single-Agent Ibrutinib in Multiply Relapsed Marginal Zone Lymphoma with MYD88 L265P Mutation

The B-cell receptor signaling pathway is important in the lymphomagenesis of many lymphomas, including marginal zone lymphoma (MZL). Herein we describe a case of extranodal MZL refractory to multiple lines of therapy. The presence of an IgM paraprotein prompted further evaluation, and the patient was found to have an MYD88L265P mutation. Treatment with ibrutinib led to a dramatic response with prompt resolution of symptoms and significant improvement in measurable sites of disease. The excellent response to ibrutinib in our patient with MYD88L265P-mutated refractory MZL supports a biological rationale for its use.Case Rep Oncol 2017;10:813 –818

Authors: Legat FJ Abstract Phototherapy and photochemotherapy (PUVA) are important treatment modalities in inflammatory skin diseases such as psoriasis and atopic dermatitis as well as in cutaneous T‑cell lymphoma (e.g., mycosis fungoides/Sezary syndrome). Many of these skin diseases are accompanied by distracting pruritus. In addition, patients may suffer from intense pruritus in systemic diseases of the kidney and liver as well as of the endocrine and hematopoietic system. UV-light during phototherapy is capable of not only improving the inflammatory skin lesions but also of reducing the pruritus in skin and sy...

CONCLUSIONS: Absolute numbers of cases of HL at our centre have increased since the roll-out of antiretroviral therapy (ART) to the public sector. The recent change in policy to make ART available to all HIV-positive patients independent of CD4+ count suggests that patients will survive longer and are therefore at increased risk of developing HL. We anticipate that numbers of HL cases will increase or remain high in the coming years, and we need to prepare for this. PMID: 30004343 [PubMed - in process]

Conclusions: Taken together, this work demonstrated that miR-181b might have the ability to overcome chemo resistance of small cell lung cancer cells, and restoration of this miRNA may represent a potential therapeutic strategy for improving chemo sensitivity in small cell lung cancer.

The comments on blood class in erythrodermic cutaneous T-cell lymphoma (CTCL) from E. Vonderheid are received with interest by our European Organisation for Research and Treatment of Cancer (EORTC) group. First, it should be noted that our recent EORTC consensus statement defined blood class according to flow cytometry [1] and included all patients with mycosis fungoides (MF) and Sezary syndrome (SS). E. Vonderheid commented on blood class in erythrodermic MF/SS, and it must be recognised that blood involvement is much more frequent in erythrodermic CTCL than patch, plaque and tumour stage MF p

The predictive value of TP53 mutation (TP53mut) and complex karyotype (CK) was analyzed in 74 mantle cell lymphoma (MCL) patients. CK and TP53mut were predictors of inferior PFS and OS, independent of age and MIPI. The combination of TP53mut and CK status stratifies the patient population into three prognostic groups (p

Histiocytic sarcomas (HS) are rare neoplasms that generally behave aggressively, yet an in-depth look at the clinicopathologic features has not been studied. This paper explores 23 unique HS occurring as de novo or secondary malignancies. Patients with a secondary HS had lower mean survival by 58.2 months (p=0.001). This suggests secondary HS behaves more aggressively than de novo HS.

Lysosomal-associated membrane protein 1 (LAMP1) contributes to tumor metastatic potential and differentiation. We performed immunohistochemical staining to investigate LAMP1 expression levels in 122 diffuse large B cell lymphoma (DLBCL) tumor samples. LAMP1 expression was higher in DLBCL tissues compared with reactive hyperplasia tissues, which was independently associated with worse survivals. LAMP1 expression is associated with poor prognosis in DLBCL.
