ABSTRACT
Large granular lymphocytic (LGL) leukaemia is a rare chronic lymphoproliferative disorder characterized by an expansion of cytotoxic T or NK cells. Despite a usually indolent evolution, most patients will require a treatment over the course of the disease because of cytopenia or symptomatic associated autoimmune disorders. First-line treatment is based on immunosuppressive agents, namely cyclophosphamide, methotrexate and ciclosporin. However, relapses are frequent, and there is no consensus on the management of relapsed/refractory patients. The implication of the JAK/STAT pathway in the pathogenesis of this disease has prompted our group to propose treatment with ruxolitinib. A series of 21 patients who received this regimen is reported here. Ten patients (47.6%) were refractory to the three main immunosuppressive drugs at the time of ruxolitinib initiation. Ruxolitinib yielded an overall response rate of 86% (n = 18/21), including 3 complete responses and 15 partial responses. With a median follow-up of 9 months, the median response duration was 4 months. One-year event-free survival and 1-year overall survival were 57% and 83% respectively. Mild side effects were observed. Biological parameters, notably neutropenia and anaemia, improved significantly, and complete molecular responses were evidenced. This study supports ruxolitinib as a valid option for the treatment of relapsed/refractory LGL leukaemia.
ABSTRACT
High-dose melphalan followed by autologous haematopoietic stem cell transplantation is widely used in newly diagnosed multiple myeloma (MM) patients as upfront therapy. However, the safety and efficacy of transplantation in patients with renal insufficiency (RI) are controversial. We followed a multicentre (16 SFGM-TC centres) prospective cohort of 50 newly diagnosed MM patients with a serum creatinine clearance of <40 mL/min at transplantation. Patients received a recommended dose of melphalan of 140 mg/m2. The primary end-point was the non-relapse mortality at Day 100. One death occurred during the first 100 days post-transplant. The median time to neutrophil engraftment was 12 days and to platelet engraftment was 13 days. The haematological response improved in 69% of patients, with best responses from partial response (PR) to very good partial response (VGPR) (10%), from PR to complete response (CR)/stringent complete response (sCR) (16%), from VGPR to CR/sCR (39%) and from CR to sCR (2%). At 2 years, the overall survival was 84%, the progression-free survival was 70% and the cumulative incidence of relapse was 20%. The renal response improved in 59% of patients, with the best renal responses post-transplant being minimal (9%), partial (2%) and complete (48%). Autologous transplantation was safe and effective in myeloma patients with RI at transplant.

The BCL2 inhibitor venetoclax is transforming the management of patients with chronic lymphocytic leukemia (CLL), given its high efficacy in relapsed/refractory CLL as observed in both early-phase and randomized clinical trials. The present study aimed to determine whether venetoclax is effective and well tolerated in patients with CLL or Richter's syndrome (RS) in a real-world setting and to highlight factors impacting survival. Data from a venetoclax French compassionate use program were collected for 67 patients (60 with CLL and 7 with RS). Most patients presented adverse genetic features, such as TP53 disruption (74%) or complex karyotype (58%). Tumor lysis syndrome was observed in 14 (22%) patients, and 16 (24%) patients were hospitalized for grade III/IV infection. In the CLL cohort, ORR was 75 %, 1-year PFS was 61% (95% CI = 47-72%) and 1-year OS 70% (95% CI = 56-80%). No impact of TP53 disruption was noted while complex karyotype was identified as a predictor of both inferior PFS (HR = 3.46; 95% CI = 1-12; log-rank p = 0.03) and OS (HR = 3.2; 95% CI = 0.9-11.4, log-rank p = 0.047). Among the seven patients with RS, two achieved an objective response to venetoclax; however, the median OS was only 1.1 month. The well-balanced safety/efficacy profile of venetoclax is confirmed in this real-world setting. Complex karyotype should be evaluated as a predictive factor of survival for patients treated by venetoclax.

Classical Philadelphia-negative myeloproliferative neoplasms include Polycythemia Vera (PV), Essential Thrombocythemia (ET) and Primary Myelofibrosis (PMF). They are characterized by the presence of driver mutations of JAK2, CALR or MPL genes. Overexpression of WT1 is used as a marker of minimal residual disease in acute myeloid leukemia, especially after allogeneic stem cell transplantation (SCT). We investigated WT1 expression at diagnosis in 152 MPN patients and showed that the WT1 transcript was overexpressed in PMFs and PVs compared to controls. In particular, WT1 transcript levels were higher in PMF than in ET and PV. WT1 transcript levels were significantly increased during myelofibrotic transformation of ET or PV. Using multivariate linear regression, high WT1 transcript levels in PMF were associated with age over 65, splenomegaly and thrombocytopenia. The ROC curve analysis showed that a level of WT1 transcript >10 WT1 copies/104ABL1 enabled the diagnosis of PMF with a specificity of 95.8% (PMF vs ET; ROC AUCâ¯=â¯0.91). In myelofibrosis, studying follow-ups of WT1 transcript showed that this marker is of interest after allogeneic SCT. These results demonstrate that WT1 overexpression is a simple marker of myelofibrosis in MPN and could be used during patient follow-up.

PURPOSE: To qualify the quality of patients sexual lives after treatment among women with breast cancer under 35 years old and compare results to the literature. METHODS: Sexual quality of life was measured for 84 women aged 20 to 35 years old at diagnosis, with two validated quality of sexual life questionnaires, Brief Index of Sexual Functioning for Women (BISF-W) and Female Sexual Function Index (FSFI), at least six months after breast cancer diagnosis. Two other questionnaires were used to allow us to understand other aspects of their life before cancer and to monitor quality of sexual life during treatment. RESULTS: Forty-three women responded to the questionnaire. The questionnaires demonstrated that more than half of them had problems with their sexuality. The mean total score was 28.08/75 for BISF-W and 25.1 for FSFI (under the cutoff score 26.55). The domain analysis showed an association between the absence of chemotherapy and scores in regard to sexual health. Only 7% had sexual disturbance detected but 49% of the patients wished to have it. CONCLUSION: Sexual dysfunction in breast cancer survivors is real, has several factors, and cannot be evaluated based only on the organic side effects induced by cancer treatment. Better monitoring and screening seems necessary in order to optimize the quality of sexual life after surviving breast cancer.
