The use of immunochemotherapy has improved the outcome of follicular lymphoma (FL). Recently, complete response at 30 months (CR30) has been suggested as a surrogate for progression-free survival. This study aimed to analyse the life expectancy of FL patients according to their status at 30 months from the start of treatment in comparison with the sex and age-matched Spanish general population (relative survival; RS). The training series comprised 263 patients consecutively diagnosed with FL in a 10-year period who needed therapy and were treated with rituximab-containing regimens. An independent cohort of 693 FL patients from the Grupo Español de Linfomas y Trasplante Autólogo de Médula Ósea (GELTAMO) group was used for validation. In the training cohort, 188 patients were in CR30, with a 10-year overall survival (OS) of 53% and 87% for non-CR30 and CR30 patients, respectively. Ten-year RS was 73% and 100%, showing no decrease in life expectancy for CR30 patients. Multivariate analysis indicated that the FL International Prognostic Index was the most important variable predicting OS in the CR30 group. The impact of CR30 status on RS was validated in the independent GELTAMO series. In conclusion, FL patients treated with immunochemotherapy who were in CR at 30 months showed similar survival to a sex- and age-matched Spanish general population.

Small lymphocytic lymphoma (SLL) is considered as the non-leukemic form of presentation of chronic lymphocytic leukemia (CLL). We have compared the features, genomic alterations, and outcome of 890 patients with CLL and SLL. One hundred and thirteen patients presented as SLL and more frequently had unmutated-IGHV, CD38high, ZAP-70high, CD49dhigh, +12, alterations in genes of NOTCH1, cell cycle, RNA metabolism, and NFkB pathways than CLL. During the follow-up, 46% of SLL patients developed CLL. Time to first treatment (TTFT) was shorter in SLL (10-year: 75% vs 62%; p = .006). Binet stage, SLL, and IGHV were independent predictive factors for TTFT. Transformation to diffuse large B-cell lymphoma was higher (10-year: 12% vs 6%; p = .003), and overall survival was shorter in SLL (10-year: 55% vs 66%; p = .004). When A0 CLL patients were excluded, only CD38 and CD49d expression, +12, and 10-year TTFT remained different between the SLL and CLL patients. In summary, SLL showed only minor clinicobiological differences when compared with CLL in similar clinical stages.

Although multiple myeloma (MM) remains an incurable disease, its treatment has improved over the past decade. This improvement has been at least in part due to the introduction of novel antimyeloma agents with new mechanisms of action, including those that target both myeloma cells and the tumor microenvironment, with antiangiogenic and immunomodulatory properties. Among these drugs, bortezomib (Velcade), a selective proteasome inhibitor, has been approved for the treatment of relapsed and refractory MM patients after one line of therapy. The toxicity profile of bortezomib includes gastrointestinal symptoms, fatigue, thrombocytopenia, peripheral neuropathy, postural hypotension, as well as some uncommon events. A patient with relapsed MM who developed recurrent bortezomib-induced rhabdomyolysis is reported. To our knowledge, this adverse event has not been previously described is this context.
