Meta AnalysisThe magnitude of improvement in progression-free survival with targeted therapy in relapsed/refractory chronic lymphocytic leukemia based on prognostic risk category: a systematic review and meta-analysis.
Chronic lymphocytic leukemia (CLL) guidelines highlight the relevance of cytogenetic and molecular testing to identify patients with high-risk genetic features. However, at the moment, only 17p del/TP53 mutation are universally recognized parameters influencing choice of therapy. ⋯ Meta-analysis of seven randomized trials comprising 2409 patients with R/R CLL revealed that improvement over traditional treatments observed with BCR or BCL2 pathway inhibitors is common to all patients, including those patients with unfavorable and favorable prognostic parameters. These findings provide quantitative evidence to support the choice of therapy in R/R CLL not solely on the basis of 17p del/TP53 mutations.

Randomized Controlled Trial Multicenter StudyObinutuzumab plus chemotherapy followed by obinutuzumab monotherapy is cost-effective vs. rituximab plus chemotherapy followed by rituximab monotherapy for previously untreated follicular lymphoma patients in the United States.
The GALLIUM trial compared obinutuzumab (GA101, G)-based chemotherapy followed by G monotherapy (G + chemo) for up to two years to rituximab (R)-based chemotherapy followed by R monotherapy (R + chemo) for up to two years in previously untreated follicular lymphoma (FL) patients. We estimated the cost-effectiveness of G + chemo versus R + chemo utilizing GALLIUM trial data and published literature. G + chemo had increased drug costs (undiscounted: $135,200 versus $127,700 for R + chemo), representing a relative increase of 5.9%. ⋯ G + chemo led to increased quality-adjusted life years (QALYs) relative to R + chemo of 0.81 (95% credible range, [CR]: 0.22-1.37), and the overall discounted incremental cost was $1,900 (95% CR: -$7,400 to $8,900). The incremental cost-effectiveness ratio was ∼$2,300 per QALY gained, and the results were highly robust to sensitivity analyses. Treatment with G + chemo compared to R + chemo is cost-effective in previously untreated FL patients in the US.

Gastrointestinal Behcet's-like disease with myelodysplastic neoplasms with trisomy 8: a French case series and literature review.
We report the 11 cases of +8-MDS/MPN associated with Behcet's-like syndrome and compare them with Behcet's disease and Crohn's disease, pool with literature cases for analysis. Data for patients with +8-MDS/MPN and Behçet's-like syndrome were collected from MINHEMON. Eleven patients had Behcet's-like syndrome and +8-MDS/MPN (median age 75 years [IQR 65-87]; M/F ratio 0.8). ⋯ Median survival did not differ between patients with Behcet's-like syndrome and +8-MDS/MPN and those with +8-MDS/MPN (n = 103) (47 vs 34 months, p = .61). AML-free survival did not differ between patients with MDS/MPN with and without Behcet's-like syndrome (p = .29). MDS/MPN with trisomy 8 can be associated with particular phenotype of ulcerative digestive disease resembling Behcet's or Crohn's disease and should be considered a single disease.
