Serum albumin or body mass index: Which prognostic factor for survival in patients with acute myeloblastic leukaemia?

Obesity has been associated with an increased risk of developing acute myeloblastic leukaemia (AML). The outcome of AML patients could thus be dependent on their nutritional status that can be evaluated by the simple measurement of serum albumin (SA) and body mass index (BMI). These two parameters could have a value as prognostic factors to guide patients' management. We evaluated the association between SA levels, BMI, and survival, evaluated as overall survival (OS) and event-free survival. Furthermore, we investigated the association between BMI, SA, and other prognostic factors of interest in AML. This retrospective single-center study included 159 patients diagnosed with AML at Nancy Hospital between 2005 and 2013, treated with aracytine and anthracycline. Forty-four percent of patients presented with normal weight while 56% were obese/overweight. Serum albumin levels were <30 g/L for 49 patients, and ≥30 g/L for 110. Thirty-four patients with low SA levels were also obese. Favourable OS was associated with SA levels ≥30 g/L (HR = 0.467; 95% CI 0.230-0.946; P = .034) but was not impacted by the BMI. Serum albumin levels appear to be an independent prognostic factor in AML and a better parameter than BMI for evaluating the nutritional status of patients at diagnosis.

Refractory diffuse large B-cell lymphoma after first-line immuno-CT: Treatment options and outcomes.

In the rituximab era, one-third of diffuse large B-cell lymphoma patients experience relapse/refractory disease after first-line anthracycline-based immunochemotherapy. Optimal management remains an unmet medical need. The aim of this study was to report the outcomes of a cohort of refractory patients according to their patterns of refractoriness and the type of salvage option. We performed a retrospective analysis, which included 104 diffuse large B-cell lymphoma patients treated at Lyon Sud University Hospital (2002-2017) who presented with refractory disease. Refractoriness was defined as progressive/stable disease during first-line treatment (primary refractory, N = 47), a partial response after the end of first-line treatment that required subsequent treatment (residual disease, N = 19), or relapse within 1 year of diagnosis after an initial complete response (CR) (early relapse, N = 38). The 2-year overall survival (OS) rates for primary refractory, early relapse, and residual disease patients were 27%, 25%, and 52%, respectively, while the event-free survival rates for those groups were 13%, 13%, and 42%, respectively. In a univariate analysis, lactate dehydrogenase level, Ann Arbor stage, poor performance status, high age-adjusted International Prognostic Index score, and age > 65 years were associated with shorter OS. The use of rituximab and platinum-based chemo during the first salvage treatment was associated with prolonged OS. In a multivariate analysis, age (HR:2.06) and rituximab use (HR:0.54) were associated with OS. Among patients <65 years who achieved a CR, autologous stem-cell transplant was associated with higher 2-year OS (90% vs 74%, P = 0.10). Patients who were treated with a targeted therapy in the context of a clinical trial after second-line treatment had a higher 2-year OS (34% vs 19%, P = 0.06). In conclusion, patients with primary refractory disease or early relapse have very poor outcomes but may benefit from rituximab retreatment during the first salvage treatment.

Recent advances in the first-line treatment of follicular non-Hodgkin lymphoma.

Follicular lymphoma (FL) is the most common type of indolent B-cell lymphoma. Twenty years ago, FL was considered an indolent lymphoma with a long survival time but without a high rate of complete remission with chemotherapies. The use of rituximab has improved the response and survival of patients with this lymphoma. More recently, development of biological knowledge and use of targeted drugs have offered new perspectives, including improvement of response rates and survival with chemo-free treatment strategies. In 2019, patients have a 10-year overall survival probability of over 70%. Histological transformation to more aggressive lymphoma and treatment relapses remain a medical challenge, especially for patients relapsing within two years. This article will review the recent advances in the treatment of FL. As the use of new drugs is directly related to the development of biological aspects, we will first summarize recent advances in biological aspects of FL.
