BACKGROUND: Patients with chronic lymphocytic leukemia (CLL) have a higher risk of developing other malignancies (OMs) compared to the general population. However, the impact of CLL-related risk factors and CLL-directed treatment is still unclear and represents the focus of this work. METHODS: We conducted a retrospective international multicenter study to assess the incidence of OMs and detect potential risk factors in 19,705 patients with CLL, small lymphocytic lymphoma, or high-count CLL-like monoclonal B-cell lymphocytosis, diagnosed between 2000 and 2016. Data collection took place between October 2020 and March 2022. FINDINGS: In 129,254 years of follow-up after CLL diagnosis, 3513 OMs were diagnosed (27.2 OMs/1000 person-years). The most common hematological OMs were Richter transformation, myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Non-melanoma skin (NMSC) and prostate cancers were the most common solid tumors (STs).The only predictor for MDS and AML development was treatment with fludarabine and cyclophosphamide with/without rituximab (FC ± R) (OR = 3.7; 95% CI = 2.79-4.91; p < 0.001). STs were more frequent in males and patients with unmutated immunoglobulin heavy variable genes (OR = 1.77; 95% CI = 1.49-2.11; p < 0.001/OR = 1.89; 95% CI = 1.6-2.24; p < 0.001).CLL-directed treatment was associated with non-melanoma skin and prostate cancers (OR = 1.8; 95% CI = 1.36-2.41; p < 0.001/OR = 2.11; 95% CI = 1.12-3.97; p = 0.021). In contrast, breast cancers were more frequent in untreated patients (OR = 0.17; 95% CI = 0.08-0.33; p < 0.001).Patients with CLL and an OM had inferior overall survival (OS) than those without. AML and MDS conferred the worst OS (p < 0.001). INTERPRETATION: OMs in CLL impact on OS. Treatment for CLL increased the risk for AML/MDS, prostate cancer, and NMSC. FCR was associated with increased risk for AML/MDS. FUNDING: AbbVie, and EU/EFPIAInnovative Medicines Initiative Joint Undertaking HARMONY grant n° 116026.

A prospective multicentre experience of early administration of anti-SARS-CoV-2 spike protein neutralizing monoclonal antibodies (MA) with efficacy among patients with hematological malignancies and early-stage COVID- 19 was reported by Weinbergerová et al. The study validated the safety and efficacy of MA early use among hematological patients with newly diagnosed early-stage COVID-19 in terms of alleviating infection course and decreasing mortality. However no reference to new variant (Delta and Omicron) or other MA (e.g., Sotrovimab) has been reported. We reported our monocentric experience of 8 aggressive lymphoma patients with Omicron infection, 7 of whom treated with this MA in our Institution between December 2021 and February 2022. Among the patients treated with Sotrovimab nobody experienced neither SARS-CoV2 reactivation, nor other infectious events. One patients on active lymphoma treatment was hospitalized for pneumonia and treated with remdesivir. In 4/8 patients negativization of molecular swab occurred concomitantly to symptoms resolution with a median of 5.25 days, while the other 4 patients remained persistently positive with a median of 26.3 days. In this group, in order to maintain the chemo/chemoimmunotherapy (CT/CIT) dose-density, lymphoma treatment was reassumed independently on molecular swab analysis. SARS-CoV-2 negativization occurred with a median of 7.7 days after the resumption of CT/CIT. The one patient treated with remdesivir, although still positive to molecular swab, restarted R-COMP regimen at symptoms resolution too, but experienced an Omicron pneumonia exacerbation. This is the first case series reported in literature of patients affected by Omicron variant in which Sotrovimab seems to provide a resolution of COVID-19 disease, even in patient with molecular swab positive persistence too. Patients with aggressive lymphoma histologies should not be deprived of the best available treatment of their disease after sotrovimab administration, even in the presence of a still positive Omicron swab.
