Efficacy and safety of the third-generation chloroethylnitrosourea fotemustine for the treatment of chemorefractory T-cell lymphomas.
Patients with recurring T-cell non-Hodgkin lymphoma (T-NHL) are incurable and candidate for investigational agents. Here, we report on five patients with T-NHL refractory to multiple chemotherapy lines, including in all cases alkylators and gemcitabine, who received the third-generation chloroethylnitrosourea fotemustine at a dose of 120 mg/m(2) every 21 d, up to eight courses. Median actual dose intensity was 79%; toxicity was manageable and mainly hematological. One complete remission, one partial remission, two protracted disease stabilization, and one transient, minor response were achieved. Time to progression ranged from 48 to 240+ d. This is the first evidence ever reporting the activity of fotemustine in end-stage T-NHL. Formal studies with this agent are warranted in T-cell malignancies
Circulating dendritic cells deficiencies as a new biomarker in classical Hodgkin lymphoma
No robust biomarkers have been yet validated to identify the recurrence of disease in classical Hodgkin Lymphoma (cHL) patients upon induction treatment. The relevance of the inflammatory microenvironment in cHL prompted us to investigate the key immunomodulator myeloid dendritic cells type-1 (mDC1), type-2 (mDC2) and plasmacytoid dendritic cells (pDC). Blood DC levels were assessed in 52 newly diagnosed patients through multiparametric flow-cytometry. All but two patients received ABVD regimen (doxorubicin, bleomycin, vinblastine, dacarbazine). The median counts of all DC subsets were lower in cHL patients than in healthy controls (P < 0·001). Median mDC counts were inferior for the advanced vs early stage patients for both mDC1s and mDC2s (P = 0·008; P = 0·0007 respectively). Also, median mDC2 counts were reduced in case of bulky (P = 0·0004) and extra-nodal (P = 0·046) disease. Patients with B symptoms had lower levels for mDC1s (P = 0·046), mDC2s (P = 0·009) and pDCs (P = 0·040). All the DC subtypes increased at the end of treatment in 26 patients (P < 0·001): 4·6-fold for mDC1, 2·4-fold for mDC2, 4·5-fold for pDC and aligned DCs subsets with the reference frequencies and the interquartile ranges of the controls. In conclusion, DCs may contribute to the disturbed immunological interplay typical of cHL, prompting a further evaluation of their value as a potential new biomarker

Fatal Outcome of COVID-19 Relapse in a Fully Vaccinated Patient with Non-Hodgkin Lymphoma Receiving Maintenance Therapy with the Anti-CD20 Monoclonal Antibody Obinutuzumab: A Case Report
Few data are available regarding the effectiveness of anti-SARS-CoV-2 vaccine in immunocompromised patients. Vaccination may have a suboptimal efficacy in this population, in particular if patients are exposed to anti-B-cell therapy. We report the virological and clinical characteristics of a patient with follicle center lymphoma under bimonthly maintenance therapy with obinutuzumab, an anti-CD20 monoclonal antibody. Despite three doses of BNT162b2 vaccine, the patient was infected by the SARS-CoV-2 Omicron variant. After an initial period of clinical and molecular remission due to early therapy with sotrovimab, the patient experienced a fatal relapse sustained by the same viral strain
90Yttrium Ibritumomab Tiuxetan as First Line Treatment for Follicular Lymphoma First Results from an International Phase II Clinical Trial
90Yttrium-Ibritumomab-Tiuxetan as First-Line Treatment for Follicular Lymphoma: 30 Months of Follow-Up Data From an International Multicenter Phase II Clinical Trial.
PURPOSEWe report on a multicenter phase II trial of (90)yttrium-ibritumomab-tiuxetan ((90)YIT) as first-line stand-alone therapy for patients with follicular lymphoma (FL). PATIENTS AND METHODSFifty-nine patients with CD20(+) FL grade 1 to 3a in stages II, III, or IV, age 50 years old or older requiring therapy were enrolled. They received (90)YIT according to standard procedure. If complete response (CR) or unconfirmed complete response (CRu) without evidence for minimal residual disease (MRD) 6 months after application of (90)YIT was achieved, patients were observed without further intervention. The same applied to patients with partial response (PR) or with stable disease (SD). Patients with CR but with persisting MRD were to receive a consolidation treatment with rituximab. Primary end point was the clinical and molecular response rate. Secondary end points were time to progression, safety, and tolerability.ResultsSix months after treatment with (90)YIT, 56% of the patients showed a CR or CRu and 31% achieved a PR. After a median follow-up of 30.6 months, the progression-free survival (PFS) was 26 months. There was a trend for shorter PFS in patients with increased lactate dehydrogenase (LDH). Of the 26 patients who had CR 12 months after (90)YIT, only three had relapsed. Median time to next treatment has not been reached. The most common toxicities were transient thrombocytopenia and leukocytopenia. Nonhematologic toxicities never exceeded grade 2 according to Common Terminology Criteria for Adverse Events (CTCAE v2.0). CONCLUSION(90)YIT is well tolerated and achieves high response rates. Patients with increased LDH tend to relapse earlier, and individuals in remission 1 year after (90)YIT appear to have long-lasting responses
