Abstract: We evaluated the clinical and neurophysiological efficacy of rituximab (RTX) in a neurophysiologically homogeneous group of patients with monoclonal gammopathy and immunoglobulin M (IgM) anti‐myelin‐associated glycoprotein antibody (anti‐MAG) demyelinating polyneuropathy. Methods Twenty three anti‐MAG‐positive polyneuropathic patients were prospectively evaluated before and for 2 years after treatment with RTX 375 mg/m 2 . The Inflammatory Neuropathy Cause and Treatment (INCAT) disability scale (INCAT‐ds), modified INCAT sensory score (mISS), Medical Research Council sum score, Patients’ Global Impression of Change scale were used, IgM levels were assessed and extensive electrophysiological examinations were performed before (T0) and 1 year (T1) and 2 years (T2) after RTX treatment. Results At T1 and T2 there was a significant reduction from T0 both in mISS and in INCAT‐ds, with a p  value 〈  0.001 in the inferential Friedman's test overall analysis. Ulnar nerve Terminal Latency Index and distal motor latency significantly changed from T0 to T1 and in the overall analysis ( p  = 0.001 and p  = 0.002), and ulnar nerve sensory nerve action potential (SNAP) amplitude was significantly increased at T2 from T1, with a p  value 〈  0.001 in the overall analysis. Analysis of the receiver‐operating characteristic curves showed that a 41.8% increase in SNAP amplitude in the ulnar nerve at T2 from T0 was a fair predictor of a mISS reduction of ≥2 points (area under the curve 0.85; p  = 0.005; sensitivity: 90.9%, specificity: 83.3%). Conclusions This study suggests that RTX is effective in patients with clinically active demyelinating anti‐MAG neuropathy over 2 years of follow‐up, and that some neurophysiological variables might be useful for monitoring this efficacy.

Abstract: Background. Immunochemotherapy is effective in follicular lymphoma (FL), but most patients (pts) eventually relapse. MRD analysis, based on the detection of Bcl-2/IGH rearrangement by highly sensitive PCR-based tools, is effective in identifying pts at risk of relapse [Ladetto Blood 2012; Pott EHA23]. However, several issues are still unresolved, including: i) which is the best tissue source and the most reliable technique; ii) which are the most predictive time points; iii) which is the role of disease kinetics during the long natural history of FL. The FIL FOLL12 prospective, phase III randomized clinical trial (EudraCT: 2012-003170-60) included a systematic MRD analysis on both peripheral blood (PB) and bone marrow (BM) taken at eight different pre-planned time points, by both nested and real time quantitative (RQ)-PCR. Therefore, it allows addressing these unresolved issues. Methods. The FOLL12 compared conventional rituximab maintenance [Salles et al, Lancet 2010] vs a combined PET/MRD response-based post-induction approach in pts with advanced FL after first line chemo-immunotherapy. Clinical results have been already reported [Luminari et al, ICML16] . PB and BM samples were centralized at four Italian Euro-MRD certified laboratories. MRD was assessed with consensus primers on Bcl-2/IGH rearrangements (MBR, mcr and minor rearrangements) by both nested and RQ-PCR at eight time points: baseline, end of induction (EoI) and every six months thereafter till month 36. MRD data were treated as a time-varying covariate and analyzed by means of flexible parametric survival model (Parmar-Royston) with the log cumulative baseline hazard function. MRD data were modeled with restricted cubic spline as function of time. Effect of fixed covariates and landmark analysis were performed with the Cox PH regression. Any estimation was reported with its 95%CI. Results. Overall, 10,702 analytical results were generated, (3,000 for marker screening and 7,702 for MRD). 780 of 786 eligible pts (99%) were screened at baseline for the presence of a molecular marker. 443/780 (57%) had a detectable Bcl-2/IGH rearrangement, as expected. High rates of MRD negativity were observed at EoI, with similar results by both techniques (87% in BM and 95% in PB by nested-PCR, 90% in BM and 95% in PB with RQ-PCR). Overall, the presence of one MRD positive result was associated during the entire follow-up period with an increased risk of relapse in the subsequent six months interval (HR for PFS 2.82, 95% CI 1.84-4.34, p & lt;0.001), independently from randomization arm (heterogenous test for HR in PFS 0.330), treatment received (HR 0.859) and FLIPI-2 (HR 0.302). Most notably, a sharp increase of HR was observed during follow-up, with time points after 6 and particularly after 12 months or later outperforming the earliest evaluation. Interestingly, very similar results were recorded in BM or PB and using nested or RQ-PCR (Figure 1A). Despite inferior performance compared to later timepoints, MRD positivity in BM at EoI was nevertheless predictive of a shorter 4y-PFS (61% vs 75% by nested-PCR and 54% vs 74% by RQ-PCR, p=0.03 and p=0.003, respectively). Moreover, a kinetic analysis showed that pts scoring MRD+ at EoI but converting to MRD- in the following time points showed superimposable outcome to pts persistently MRD- (HR for PFS 0.66, 95% CI 0.24-1.82, p=0.420), while pts scoring MRD- at EoI but then converting to MRD+ showed a worse outcome (HR for PFS 1.75, 95% CI 1.21-2.53, p=0.003) (Figure 1B). Actually, Kaplan Meier landmark analyses stratified by updated MRD results at each punctual timepoint after EoI were overall highly discriminant in terms of PFS, with PB results (Figure 1C) substantially overlapping BM performances from months 12 after EoI (not shown) and thereafter. Conclusions. This comprehensive MRD study in FL clearly indicates that: i) punctual MRD analysis is predictive of poor outcome at multiple pre-planned time points taken over a 36 months period; ii) both nested and RQ-PCR performed adequately, the latter being preferable as broadly used and internationally standardized; iii) BM allows better prediction at the early time points but, starting from month 12 after EoI PB is superimposable to BM, allowing effective and reliable long-term non-invasive MRD monitoring; iv) the high predictive value of punctual time point analysis is further improved by a kinetic approach to the interpretation of MRD results.

Abstract: In IgM monoclonal gammopathies MYD88L265P is a prognostic and predictive biomarker of therapy response. MYD88L265P detection is mainly performed by allele-specific quantitative PCR (ASqPCR), however recently, droplet digital PCR (ddPCR) has been proved to be suitable for MYD88L265P screening and minimal residual disease monitoring (MRD). This study compared ASqPCR and ddPCR to define the most sensitive method for MYD88L265P detection in bone marrow (BM), peripheral blood (PB) sorted or unsorted CD19+ cells, and in plasma cell-free DNA (cfDNA). Overall, the analysis showed a good concordance rate (74%) between the two methods, especially in BM samples, while discordances (26%) were mostly in favor of ddPCR (ddPCR+ vs. ASqPCR-) and were particularly evident in samples with low mutational burden, such as PB and cfDNA. This study highlights ddPCR as a feasible approach for MYD88L265P detection across different specimen types (including cfDNA). Interestingly, its high sensitivity makes CD19+ selection dispensable. On the other hand, our results showed that MYD88L265P detection on PB samples, especially with ASqPCR, is suboptimal for screening and MRD analysis. Finally, significantly different MYD88L265P mutational levels observed between Waldenström Macroglobulinemia and IgM monoclonal gammopathy of undetermined significance patients suggest the need for further studies in order to identify possible correlations between mutational levels and risk of progression to Waldenström.

Abstract: The addition of oxaliplatin to the widely employed De Gramont schedule (FOLFOX regimen) in patients with metastatic colorectal cancer improved their outcome with a moderate toxicity pattern. The adaptation of the delivery rate of 5-fluorouracil, leucovorin and oxaliplatin to circadian rhythms (chronotherapy) resulted in a very high drug tolerability with clinical results at least comparable to those achieved with the FOLFOX regimen. However, chronomodulated infusion seemed to be more expensive, requiring dedicated electronic pumps and several disposable materials. The present study aimed to compare the direct costs of the two regimens and to determine whether chronotherapy was effectively more expensive than the FOLFOX regimen. Study design The direct costs of drug delivery devices derived from various publicly available sources and of toxicity management as extrapolated from two published studies considering comparable patient subsets were added and compared. Results Pump, central venous system and disposable materials for a single chronotherapy cycle were € 193 or € 212 according to whether the pumps were bought or rented, compared to € 58 for the FOLFOX regimen. Toxicity management costs were € 144 vs € 288 for the two schemes, respectively. Globally, a single course of chronotherapy cost € 337 or € 356, whereas a single FOLFOX cycle cost € 346. Conclusions Direct costs for a single chronotherapy cycle appeared to be comparable to a single course of the FOLFOX regimen. In fact, the major material cost of chronochemotherapy devices was balanced by a better tolerability profile. The overall improvement in quality of life with chronochemotherapy affecting indirect costs, such as reduction of work, and intangible costs is worthy of further pharmacoeconomic attention.

Abstract: Background: Successful tyrosine-kinase inhibitors (TKIs) discontinuation has been obtained in some patients (pts) with chronic-phase chronic myeloid leukemia (CP-CML). Careful molecular monitoring after discontinuation is the key to guarantee the safety, in terms of prompt resumption of therapy according to retreatment threshold criteria. It was observed that the majority of relapses usually occur during the first 6 months after TKI discontinuation [Saussele S, Lancet Oncol 2018; Etienne G, JCO 2017], accounting for the monthly quantitative PCR (qPCR) that all prospective protocols included in the trial design at least during the first half-year. Two studies [Kong HJ, Cancer 2017; Shanmuganathan N, Blood 2019] investigated if performing molecular analysis with a different and less "cautious" timeframe yields comparable efficacy with logistical issues reduction. Here we retrospectively evaluated how molecular monitoring has been conducted in Italy on a cohort of patients not included in any prospective trial with follow-up visits. Methods: The outcome of Italian patients with CP-CML who discontinued TKIs per clinical practice has recently been reported [Fava C, Haematologica 2019]. For the purpose of the present study, all the 32 participating centers were required to provide dates and molecular results available for each enrolled patient in the first 24 months after TKI stop. Descriptive analysis was carried out. The average time to the loss of major molecular response (MMR), the frequency of the visits (monitoring) and the occurrence of loss of MMR within the first 6 months, between 6-12 months, and 13-24 months were computed. When appropriate non-parametric tests were used to test for differences. Results: 227 chronic phase CML pts were included in this sub-analysis. Median age at TKI discontinuation was 58.73 years and median follow up since TFR was 2.03 years. In this timeframe every patient had a mean of 7.95 appointments for molecular evaluation. Overall, 1804 analysis were performed, of which 18.2% happened in the first three months and 38.2% in the first six months. During the first three months of TKI discontinuation, 40 pts (17.6%) didn't have any molecular assessment; 78 pts (34.4%) had only 1 qPCR performed, 77 pts (33.9%) 2 qPCR, 31 pts (13.7%) 3 qPCR and 1 pt (0.4%) 4 qPCR. For the first six months after TKI stop, 7 pts (3.1%) didn't undergo any BCR-ABL1 evaluation; 37 pts (16.3%) had only 1 analysis, 60 pts (26.4%) 2 analysis, 37 pts (16.3%) 3 analysis, 28 pts (12.3%) were evaluated 4 times, 40 pts (17.6%) 5 times, 17 pts (7.5%) 6 times and only 1 pt (0.4%) 7 times. The majority of visits fell between the 3rd and the 7th month after TKI interruption (Figure 1) with 84 pts (52.2%) being evaluated at month 3, 96 pts (59.6%) at month 4, 80 pts (49.7%) at month 5, 89 pts (55.3%) at month 6, 101 pts (62.7%) at month 7. In the first six months the visits occurred with a mean interval of 1.44 months; between months 7-12 molecular evaluations were performed every 1.94 months; during the second year of discontinuation (months 13-24) every 2.89 months (p 〈 0.001). Seventy-one pts lost major molecular response (MMR) in a mean time of 5.56 months. As expected, 55 pts (77.5%) lost MMR during the first six months whereas 16 pts (22.6%) relapsed later on: 3 pts (4.2) relapsed during the first month, 7 pts (9.9%) after two months, 13 pts (18.3%) after three, 19 pts (26.8%) after four, 8 pts (11.3%) after five months and 5 pts (7%) at six months. Only 6 patients lost MMR after 12 months of follow-up in TFR. All patients regained at least MMR after TKI resumption, and no progression occurred. Finally, we evaluated the number of patients who would experience a delay in the diagnosis of MMR loss if a three-months monitoring schedule was adopted. In the first 6 months, 15 pts (27.3%) would have a one month delay, 22 (40%) a 2 months delay; 18 pts (32.7%) would have a right timing. Very few patients would experience a delay in the following months (Figure 2). Discussion: The safety of TFR relies consistently on the management of patients off-therapy especially during the first 6 months, when molecular relapses more often occur. Our retrospective analysis showed that a less intense frequency of monitoring did not affect the success of TFR nor put pts at risk of progression. However, these data confirm that the first 6 months off-treatment require a more stringent follow-up for early detection of MMR loss.

Abstract: Background. The World Health Organization defines Waldenström Macroglobulinemia (WM) as a lymphoplasmacytic lymphoma associated with a serum immunoglobulin M (IgM) monoclonal protein. Since bone marrow (BM) infiltration is always present, while extramedullary involvement is infrequent, trephine BM biopsy is mandatory based on currently used diagnostic criteria, while multiparameter flow cytometry (MFC) studies are recommended to support the diagnosis (Owen et al, 2003). Next generation flow cytometry using panels with 8 to 17 monoclonal antibodies (MoAb), high number of cell acquisitions and appropriate software have shown an increased sensitivity, being able to detect one tumor cell among 10.000 normal cells (10-4) or even more. Aims of the study. Here we report an extensive phenotypic characterization by eight color MFC of a large prospective cohort of newly diagnosed WM patients, enrolled in the multicenter, observational trial BIO-WM (NCT03521596). In this study we evaluated the potential role of MFC on BM and peripheral blood (PB) samples as an alternative to BM biopsy in the diagnostic work-up of WM, with the final goal to assess the feasibility of a non-invasive or at least less invasive diagnostics. Methods. The diagnosis of WM was made using the criteria of the Second International Workshop on WM. Patients without bone marrow biopsy were excluded from the analysis. Whole BM and PB samples were processed following the bulk lysis protocol and stained using 8-color combination of the following fluorochrome-conjugated monoclonal antibodies: cIgM, CD56, CD5, CD19, CyK, CyL, CD38, CD45 (screening panel). CD5- lymphoproliferative disorders with two populations in different maturation stage showing identical cytoplasmatic light chain restriction underwent further characterization with six 8 color-panels (characterization panel). A minimum of 1x106/L cells per tube was acquired. The full list of monoclonal antibodies is reported in Table 1. Results. We analyzed 173 prospective patients with a histologic diagnosis of WM, either asymptomatic (n=46, 27%) or symptomatic (n=127, 73%). Their baseline characteristics are reported in Table 2. MFC results on BM samples collected at diagnosis were available in 165 patients. The median white blood cell (WBC) count was 13.5 x 109/L (IQR: 4.9-94) and the median number of cell acquisitions was 1.16 x 106 (IQR: 0.91-1.58). Clonal CD19+ B-cells were detected by MFC in 155/165 cases (94%) and showed k light chain restriction in 76% of cases. The median percentage of clonal CD19+ B-cells out of total BM WBC was 5.9% (IQR: 2.9-12.4). Twelve cases out of 165 (7%) were CD5+. The complete phenotype of clonal B CD19+ lymphocytes is shown in Figure 1. Clonal CD38+ plasma cells were detected in BM samples in 86% of cases and were CD20+ in 51% of cases. The median percentage of clonal CD38+ plasma cells out of total BM WBC was 0.18% (IQR: 0.05-0.47). The complete antigenic expression of clonal plasma cells is shown in Figure 2. The MYD88 (L265P) mutation was found with droplet digital polymerase chain reaction (dd-PCR) in 95% of patients with detectable clonal CD19+ B-cells in BM samples, without significant difference between CD5- and CD5+ cases (95% versus 93%, P=0.698). Paired BM and PB samples were available in 157 patients. Clonal CD19+ B-cells were detected in BM samples in 149/157 cases (95%) and in PB samples in 98/157 cases (58%). Overall, there was a slight agreement between BM and PB MFC results according to Landis and Koch scale (63%, k = 0.138). Conclusions. The comparison of MFC results on BM samples with BM histology in this large prospective cohort of WM patients suggests that eight-color MFC is highly sensitive and is able to identify the majority of patients with WM. Conversely, the comparison of MFC results on paired BM and PB samples indicates that MFC on PB samples has a low sensitivity, missing approximately 40% of cases. The integration of MFC results on BM samples with MYD88 mutation status assessed with a highly sensitive method such as dd-PCR may be considered as an alternative, less invasive method for the diagnosis of WM. Further analyses within this trial will assess the role of MFC combined with molecular profile of patients for the differential diagnosis between WM and other mature B-cell lymphoproliferative disorders as well as for the discrimination between WM and IgM monoclonal gammopathy of undetermined significance.

Abstract: Background. Bendamustine is a cytotoxic alkylating drug with a broad range of indications as a single agent or in combination therapy in lymphoid neoplasia patients. However, its tolerability in elderly patients is still debated. Methods: An observational, retrospective study was carried out; patients with chronic lymphocytic leukemia (CLL) or lymphoma, aged ≥ 65 years old, treated with bendamustine-based regimens in first or subsequent lines between 2010 and 2020 were considered eligible. Results: Overall, 179 patients aged ≥ 65 years were enrolled, 53% between 71 and 79 years old. Cumulative Illness Rating Scale (CIRS) comorbidity score was ≥6 in 54% patients. Overall survival (OS) at 12 months was 95% (95% confidence interval [CI]: 90–97%); after a median follow up of 50 months, median OS was 84 months. The overall response rate was 87%, with 56% complete responses; the median time to progression (TTP) was 61 months. The baseline factors affecting OS by multivariable analysis were sex, histological diagnosis, renal function, and planned bendamustine dose, while only type of lymphoma and bendamustine dose impacted on TTP. Main adverse events were neutropenia (grade ≥ 3: 43%) and infections (any grade: 36%), with 17% of patients requiring hospital admission. Conclusions: The responses to bendamustine, as well as survival, are relevant even in advanced age patients, with a manageable incidence of acute toxicity.
