ObjectiveThe systemic immune-inflammation index (SII) based on neutrophil, platelet and lymphocyte counts, is a prognostic biomarker in some solid cancers. However, the prognostic value of SII has not yet been validated. This study was to evaluate the role of SII in predicting survival for patients with diffuse large B cell lymphoma (DLBCL).MethodsWe retrospectively investigated 224 patients with DLBCL between August 2005 and October 2018. Kaplan–Meier analysis and Cox proportional hazard models were used to assess the prognostic value of SII.ResultsIn the ROC curve analysis, SII had the highest AUC and was more accurate as a prognostic factor. Patients with higher SII tended to have higher level of LDH, more advanced stage, poor PS, and high IPI score compared with low SII group. In univariate analyses, SII, PLR and NLR were all prognostic for progression-free survival and overall survival. Moreover, only SII, older age, HBSAg-positive and IPI were the independent prognostic factors for patients in multivariate analysis. The nomogram based on SII, older age, HBSAg status and IPI showed accurate prognostic ability for predicting 3-years and 5-years survival rates (c-index, 0.791) compared to the IPI alone (c-index, 0.716).ConclusionSII was a powerful tool for predicting outcome in patients with DLBCL. It might assist the separation of high-risk patients among patients with the same IPI.

Acute myeloid leukemia (AML) originates from the abnormal clonal proliferation of myeloblasts. Immunoglobulin is secreted by B cells. AML with monoclonal antibody often indicates a poor prognosis. Here we report a case of BCOR mutation and TLS-ERG expression in AML with monoclonal immunoglobulinemia. After chemotherapy, the patient achieved bone marrow complete remission . BCOR mutation and TLS-ERG fusion gene in patient's bone marrow were not detected, at the same time, peripheral blood monoclonal immunoglobulin also disappeared. BCOR mutation or TLS-ERG fusion gene expression is associated with poor prognosis, AML with monoclonal immunoglobulin may have the same prognostic significance.

AbstractrRecently, novel drugs like venetoclax plus 5-azacytidine (VA) were reported to have promising efficacy in refractory acute myeloid leukemia (AML). However, there are still some cases presented with novel drugs resistance, and its genetics composition and clinical phenotype are urging to study. We described a 58-year-old patient who was resistant to intensive chemotherapy. This refractory AML was presented with the persistence of RUNX1, IDH1 and DNMT3A mutations. RUNX1 mutations disappeared and leukemia cutis ensued after multiple chemotherapies. Leukemia cutis exhibited NRAS mutations in addition to IDH1 and DNMT3A mutations. With the VA salvage treatment, platelets were recovered to the normal level and blasts in bone marrow and peripheral blood were moderately controlled. However, leukemia cutis did not resolve. Unexpectedly, BM blasts obtained the new NRAS mutations after VA treatment, and consequently experienced leukostasis with two distinct leukemia clones. After survival of 230 days, this patient died because of spontaneous cerebral hemorrhage. This case highlights presentation of leukemia cutis with simultaneous mutations of IDH1, DNMT3A and NRAS in AML patients might act as a resistant niche to avoid the toxicity of multiple drugs including VA. There is unmet need to validate this result in the clinical trials or a large cohort of patients in the future.
