Supplementary Table from Lenalidomide plus R-GDP (R2-GDP) in Relapsed/Refractory Diffuse Large B-Cell Lymphoma: Final Results of the R2-GDP-GOTEL Trial and Immune Biomarker Subanalysis

Purpose:New therapeutic options are needed in relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL). Lenalidomide-based schedules can reverse rituximab refractoriness in lymphoma.Patients and Methods:In the phase II R2-GDP trial, 78 patients unsuitable for autologous stem cell transplant received treatment with the following schedule: lenalidomide 10 mg Days (D)1–14, rituximab 375 mg/m2 D1, cisplatin 60 mg/m2 D1, gemcitabine 750 mg/m2 D1 and D8, and dexamethasone 20 mg D1–3, up to 6 cycles (induction phase), followed by lenalidomide 10 mg (or last lenalidomide dose received) D1–21 every 28 days (maintenance phase). Primary endpoint was overall response rate (ORR). Secondary endpoints included progression-free survival (PFS), overall survival (OS), safety, and monitorization of key circulating immune biomarkers (EU Clinical Trials Register number: EudraCT 2014-001620-29).Results:After a median follow-up of 37 months, ORR was 60.2% [37.1% complete responses (CR) and 23.1% partial responses (PR)]. Median OS was 12 months (47 vs. 6 months in CR vs. no CR); median PFS was 9 months (34 vs. 5 months in CR vs. no CR). In the primary refractory population, ORR was 45.5% (21.2% CR and 24.3% PR). Most common grade 3–4 adverse events were thrombocytopenia (60.2%), neutropenia (60.2%), anemia (26.9%), infections (15.3%), and febrile neutropenia (14.1%). Complete responses were associated with a sharp decrease in circulating myeloid-derived suppressor cells and regulatory T cells.Conclusions:R2-GDP schedule is feasible and highly active in R/R DLBCL, including the primary refractory population. Immune biomarkers showed differences in responders versus progressors.

In Spain, due to the lack of data at national level a lung cancer registry, the Thoracic Tumour Registry (TTR), was created. Such registry should demonstrate comparability with population-based data to ensure representativeness at population level. The aim is to compare the socio-demographic characteristics of the TTR with incidence data from the Red de Registros de Cáncer (REDECAN) and mortality data from the Instituto Nacional de Estadística (INE).Lung cancer data sources available to date, REDECAN and INE, were used. Lung cancer cases overall and disaggregated by sex and age groups were collected from each source of information and data were compared for the period 2017-2020. Sex and age group proportions of TTR were calculated for both databases (which collect incidence and mortality data), for the entire study period and broken down by year.A total of 17,109 incident lung cancer cases from the TTR, 58,668 estimated incident cases from REDECAN and 88,083 deaths registered from INE between 2017 and 2020 were included. In terms of sex, the proportions are very similar between the three sources and the differences do not exceed 4%. In terms of age, the differences are not large, being larger for mortality data in the older age group from the INE versus the TTR.The TTR seems to be representative of lung cancer cases diagnosed in Spain between 2019 and 2020, both by sex and age. This allows us to accurately characterise the status of this disease, which is the leading cause of cancer death in Spain, and that the analysis of results obtained from the RTT can be applied to cases of lung cancer diagnosed in our country.

Management of chronic pain is crucial to improve the quality of life of cancer and palliative care patients. Opioid-based treatments used to control pain can be prolonged over time. Unfortunately, constipation is one of the most disturbing adverse effects of long-term use of opioids. Opioid-induced constipation (OIC) occurs when opioids bind to the specific receptors present in the gastrointestinal (GI) tract, and can affect any patients receiving chronic opioid therapy, including cancer patients. The limited efficacy of laxatives to treat OIC symptoms prompted the search for new therapeutic strategies. Peripherally acting μ-opioid receptor antagonists (PAMORAs) have recently emerged as new effective drugs for OIC management due to their specific binding to enteric μ-receptors. Little information is available on the use of PAMORAs in real-life practice for OIC treatment in cancer patients. In this paper, a panel of experts specializing in cancer and palliative care pools their clinical experience with PAMORAs in cancer patients presenting OIC and highlights the importance of timing and choice of therapy in achieving prompt OIC management and benefitting patients.
