- Mantle cell lymphoma (MCL) is a rare, aggressive, incurable B-cell malignancy. Ibrutinib has been shown to be highly active for patients with relapsed/refractory (R/R) MCL. The RAY trial (MCL3001) was a phase 3, randomized, open-label, multicenter study that compared ibrutinib with temsirolimus in patients with R/R MCL. Active disease is frequently associated with impaired functional status and reduced well-being. Therefore, the current study employed two patient-reported outcome instruments, the Functional Assessment of Cancer Therapy-Lymphoma (FACT-Lym) and the EQ-5D-5L, to assess symptoms, well-being, health status, and health-related quality of life of patients on treatment within the RAY trial. We found that patients on ibrutinib had substantial improvement in FACT-Lym subscale and total scores, and had improvement in EQ-5D-5L utility and VAS scores compared with temsirolimus patients, indicating a superior well-being. These improvements in well-being correlated with clinical response, indicating that better health-related quality of life was associated with decreased disease burden.

- P-glycoprotein (PGP) over-expression on malignant cells is associated with poor prognosis and treatment outcome due to the development of a multidrug resistance phenotype. In this study, we analyzed the correlation between expression of PGP and lymphoid antigens (Ly) on leukemic myeloblasts versus response to therapy and survival in acute myeloid leukemia (AML). Fifty-one consecutive patients, aged 16–75 (median age 44.6 years), diagnosed with de novo AML between 1997 and 2000, and who received at least one induction chemotherapy course, were enrolled in the study. Expression of PGP on ≥10% of the myeloblasts (PGP+AML) at the time of diagnosis was observed in 21 patients (41%). The complete remission rate did not differ between PGP+ (13/21) and PGP− (20/30) patients (62 vs. 67%). Twelve of the 51 patients (24%) were still alive after a median follow-up time of 11.5 years (range 10.7–13.1). The Ly+AML patients showed significantly better overall survival compared with Ly−AML patients (8/18 vs. 4/33 patients alive at the last follow-up, P = 0.003). The subgroup of patients with co-expression of PGP and Ly also showed better overall survival compared with PGP+AML patients without Ly expression (4/8 vs. 0/13 patients alive at the last follow-up; P = 0.04). Our results suggest that expression of lymphoid antigens on PGP+ myeloblasts in AML can positively affect survival in AML patients, mainly due to a decreased relapse risk and better survival. Although the small number of patient may be perceived as a limitation of the study, the long follow-up period strengthens its value. Further prospective trials are needed to obtain more information concerning the association between PGP and lymphoid antigens in AML, which would put our results in their ultimate proper context.

- BACKGROUND Ibrutinib, a Bruton's tyrosine kinase inhibitor, may have clinical benefit when administered in combination with bendamustine and rituximab and followed by rituximab maintenance therapy in older patients with untreated mantle-cell lymphoma. METHODS We randomly assigned patients 65 years of age or older to receive ibrutinib (560 mg, administered orally once daily until disease progression or unacceptable toxic effects) or placebo, plus six cycles of bendamustine (90 mg per square meter of body-surface area) and rituximab (375 mg per square meter). Patients with an objective response (complete or partial response) received rituximab maintenance therapy, administered every 8 weeks for up to 12 additional doses. The primary end point was progression-free survival as assessed by the investigators. Overall survival and safety were also assessed. RESULTS Among 523 patients, 261 were randomly assigned to receive ibrutinib and 262 to receive placebo. At a median follow-up of 84.7 months, the median progression-free survival was 80.6 months in the ibrutinib group and 52.9 months in the placebo group (hazard ratio for disease progression or death, 0.75; 95% confidence interval, 0.59 to 0.96; P=0.01). The percentage of patients with a complete response was 65.5% in the ibrutinib group and 57.6% in the placebo group (P=0.06). Overall survival was similar in the two groups. The incidence of grade 3 or 4 adverse events during treatment was 81.5% in the ibrutinib group and 77.3% in the placebo group. CONCLUSIONS Ibrutinib treatment in combination with standard chemoimmunotherapy significantly prolonged progression-free survival. The safety profile of the combined therapy was consistent with the known profiles of the individual drugs.

- The genetic mechanisms underlying disease progression, relapse and therapy resistance in mantle cell lymphoma (MCL) remain largely unknown. Whole-exome sequencing was performed in 27 MCL samples from 13 patients, representing the largest analyzed series of consecutive biopsies obtained at diagnosis and/or relapse for this type of lymphoma. Eighteen genes were found to be recurrently mutated in these samples, including known (ATM, MEF2B and MLL2) and novel mutation targets (S1PR1 and CARD11). CARD11, a scaffold protein required for B-cell receptor (BCR)-induced NF-kappa B activation, was subsequently screened in an additional 173 MCL samples and mutations were observed in 5.5% of cases. Based on in vitro cell line-based experiments, overexpression of CARD11 mutants were demonstrated to confer resistance to the BCR-inhibitor ibrutinib and NF-kappa B-inhibitor lenalidomide. Genetic alterations acquired in the relapse samples were found to be largely non-recurrent, in line with the branched evolutionary pattern of clonal evolution observed in most cases. In summary, this study highlights the genetic heterogeneity in MCL, in particular at relapse, and provides for the first time genetic evidence of BCR/NF-kappa B activation in a subset of MCL.
