JCO The primary analysis of the Early positron emission tomography (ePET) Response-Adapted Treatment in localized Hodgkin Lymphoma H10 Trial demonstrated that in ePET-negative patients, the risk of relapse increased when involved-node radiotherapy (INRT) was omitted and that in ePET-positive patients, switching from doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) to bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPPesc) significantly improved 5-year progression-free survival (PFS). Here, we report the final results of a preplanned analysis at a 10-year follow-up. In the favorable (F) ePET-negative group, the 10-year PFS rates were 98.

Article Synopsis
  • Primary mediastinal B-cell lymphoma (PMBL) is a rare but aggressive form of lymphoma that typically has a good prognosis, although 10-15% of cases are resistant to chemotherapy.
  • Researchers studied a group of 120 patients to identify which ones might be at higher risk for poor outcomes using gene expression profiling.
  • Their findings showed that high expression of the genes PDL1 and PDL2 is linked to worse survival rates, suggesting that these patients may need alternative treatments like checkpoint inhibitors instead of standard chemotherapy.

TOXICITY OF TARGETED THERAPIES AND IMMUNOTHERAPY WITH CHECKPOINT INHIBITORS IN HODGKIN LYMPHOMA. In patients at increased risk of recurrence or progression after autotransplantation, or in cases of relapse after autotransplantation or after at least two lines of treatment when intensive multidrug therapy is no longer a treatment option, targeted anti-CD30 therapy with brentuximab vedotin may be proposed. Brentuximab vedotin is a monoclonal antibody directed against CD30 and coupled with an anti-microtubule cytotoxic agent, monomethyl auristatin E (MMAE).

Low baseline NK-cell counts (NKCCs) in patients with diffuse large B-cell lymphoma (DLBCL) are associated with a poor prognosis. The REMARC phase III trial (NCT01122472) showed that lenalidomide maintenance prolonged PFS in rituximab-chemotherapy responders. We conducted a REMARC ancillary study analysing the impact of lenalidomide maintenance on the prognostic value of low NKCCs.

Article Synopsis
  • The SARS-CoV-2 pandemic poses significant risks to immunosuppressed patients with hematological malignancies, leading to higher illness and death rates, even after vaccination.
  • Many of these patients showed weak immune responses, particularly low levels of anti-SARS-CoV-2 IgG post-vaccination, prompting the use of monoclonal antibodies for prevention and highlighting the need to study T cell responses more closely.
  • In a study of 47 hematological malignancy patients, only a minority developed strong immune responses to the BNT162b2 mRNA vaccine, and the presence of Th1 immune responses was found to be crucial for protection against severe SARS-CoV-2 infection, unlike Th2 responses or IgG

The term lymphoma includes a wide variety of different clinical entities including diffuse large B-cell lymphomas (DLBCL). Skeletal muscle or intramuscular lymphomas represent less than 2% of B-cell Lymphoma, they are quite rare, even more in the orofacial area. We present the case of a painless growing mass of the right cheek mimicking a chronic oral cellulitis in a 34-year-old man.

Article Synopsis
  • Stage IIB Hodgkin lymphoma (HL) patients with certain risk factors have a poor prognosis and are treated either as limited or advanced stage, with differing clinical trials comparing these treatment approaches.
  • A study involving 148 patients showed that baseline total metabolic tumor volume (TMTV) and responses after two cycles of chemotherapy significantly influenced progression-free survival rates, with a median follow-up of 4.1 years showing PFS rates around 88%.
  • The findings suggest that both upfront ABVD plus radiation therapy and upfront escBEACOPP without radiotherapy yield similar outcomes in these high-risk patients, while TMTV can effectively stratify their risk at baseline.

Purpose: The AHL2011 study (ClinicalTrials.gov identifier: NCT01358747) demonstrated that a positron emission tomography (PET)-driven de-escalation strategy after two cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) provides similar progression-free survival (PFS) and overall survival (OS) and reduces early toxicity compared with a nonmonitored standard treatment. Here, we report, with a prolonged follow-up, the final study results.

Article Synopsis
  • The study examines the resistance to anti-PD-1 treatment in patients with classical Hodgkin lymphoma (cHL), focusing on the tumor microenvironment of individuals who relapsed post-treatment.
  • It analyzes tumor samples from eight patients—four who received anti-PD-1 therapy and four who did not—using cellular and histological methods to assess immune cell markers and characteristics.
  • Findings reveal a depletion of CD8+ T lymphocytes and an increased expression of LAG-3 in CD4+ T lymphocytes in patients who had undergone anti-PD-1 therapy, suggesting potential mechanisms of resistance to this immunotherapy.

Purpose: The prospective, randomized AHL2011 trial demonstrated that the use of the doxorubicin, bleomycin, vinblastine, and dacarbazine regimen (ABVD) after two cycles of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone (BEACOPP) in early responders on the basis of a positron emission tomography (PET)-driven strategy was safe and minimized toxicity compared with standard 6 BEACOPP cycles. This substudy investigated the benefit of this strategy in gonadal function and fertility in patients under 45 years old.

Methods: Ovarian function was assessed by serum measurement of follicle-stimulating hormone (FSH), estradiol, and anti-müllerian hormone in women, and semen analysis, FSH, and testosterone levels were used to evaluate testicular function in men at baseline, end of treatment, and during 5 years of follow-up.

Classical Hodgkin lymphoma is a neoplastic hematological disease. Standard first-line therapy, including chemotherapy and radiotherapy, is curative in >85% of early-stage patients, with a 5-year survival rate of >95%. However, approximately 15% of patients have hard-to-treat lymphoma with poor outcomes, and new treatment strategies are needed for these young adults.

Around 30-50% of classical Hodgkin lymphoma (cHL) cases in immunocompetent individuals from industrialized countries are associated with the B-lymphotropic Epstein-Barr virus (EBV). Although natural killer (NK) cells exhibit anti-viral and anti-tumoral functions, virtually nothing is known about quantitative and qualitative differences in NK cells in patients with EBV+ cHL vs. EBV- cHL.

The low abundance of Hodgkin/Reed-Sternberg (HRS) cells in lymph node biopsies in classical Hodgkin lymphoma (cHL) complicates the analysis of somatic genetic alterations in HRS cells. As circulating cell-free DNA (cfDNA) contains circulating tumor DNA (ctDNA) from HRS cells, we prospectively collected cfDNA from 177 patients with newly diagnosed, mostly early-stage cHL in a monocentric study at Leuven, Belgium (n = 59) and the multicentric BREACH study by Lymphoma Study Association (n = 118). To catalog the patterns and frequencies of genomic copy number aberrations (CNAs), cfDNA was sequenced at low coverage (0.

Anti-CD20 monoclonal antibody is a cornerstone therapy for follicular lymphoma. Following anti-CD20 therapy, a potential decrease in CD20 antigen, and therefore a loss of the tumor target might be expected. However, the incidence and clinical significance of CD20 loss on tumor cells in patients with relapsed or refractory follicular lymphoma are unknown.
