Summary: Late toxicities can impact survivorship in patients with classical Hodgkin lymphoma (cHL) with pulmonary toxicity after bleomycin‐containing chemotherapy being a concern. The incidence of pulmonary diseases was examined in this Danish population‐based study. A total of 1474 adult patients with cHL treated with ABVD (doxorubicin, bleomycin, vinblastine and dacarbazine) or BEACOPP (bleomycin, vincristine, etoposide, doxorubicin, cyclophosphamide, procarbazine and prednisone) between 2000 and 2018 were included along with 7370 age‐ and sex‐matched comparators from the background population. Median follow‐up was 8.6 years for the patients. Patients with cHL had increased risk of incident pulmonary diseases (HR 2.91 [95% CI 2.30–3.68]), with a 10‐year cumulative risk of 7.4% versus 2.9% for comparators. Excess risks were observed for interstitial lung diseases (HR 15.84 [95% CI 9.35–26.84]) and chronic obstructive pulmonary disease (HR 1.99 [95% CI 1.43–2.76]), with a 10‐year cumulative risk of 4.1% and 3.5% respectively for patients. No excess risk was observed for asthma (HR 0.82 [95% CI 0.43–1.56]). Risk factors for interstitial lung diseases were age ≥60 years, the presence of B‐symptoms and low albumin. These findings document a significant burden of pulmonary diseases among patients with cHL and emphasize the importance of diagnostic work‐up of pulmonary symptoms. [ABSTRACT FROM AUTHOR]

A study published in the British Journal of Haematology examined the impact of COVID-19 on patients with B-cell non-Hodgkin lymphoma (B-NHL) who received bispecific antibodies. The study included 130 Danish patients who were treated with glofitamab or epcoritamab. Of the 43 patients who were infected with COVID-19, the majority were in complete remission at the time of diagnosis. The severity of COVID-19 symptoms varied, with 2 patients experiencing critical symptoms, 2 experiencing severe symptoms, and 30 experiencing non-severe symptoms. Hospitalization was required for 16 patients, and the most common treatments prescribed were sotrovimab and remdesivir. Overall, the study found low mortality rates from COVID-19 infection in patients with B-NHL after bispecific CD20xCD3 therapy. The study also compared the mortality rates of patients who received bispecific antibodies to those treated with CAR-T-cell therapy, finding that bispecific antibody patients had a lower mortality rate. The study concludes that bispecific CD20xCD3 antibodies can be safely prescribed to lymphoma patients who have been vaccinated for COVID-19 with currently circulating virus variants.

Involvement of the internal female reproductive organs by diffuse large B-cell lymphoma ( DLBCL) is uncommon, and there are sparse data describing the outcomes of such cases. In total, 678 female patients with DLBCL staged with positron emission tomography/computed tomography and treated with rituximab-containing chemotherapy were identified from databases in Denmark, Great Britain, Australia, and Canada. Overall, 27/678 (4%) had internal reproductive organ involvement: uterus ( n = 14), ovaries ( n = 10) or both ( n = 3). In multivariate analysis, women with uterine DLBCL experienced inferior progression-free survival and overall survival compared to those without reproductive organ involvement, whereas ovarian DLBCL was not predictive of outcome. Secondary central nervous system ( CNS) involvement ( SCNS) occurred in 7/17 (41%) women with uterine DLBCL (two patients with concomitant ovarian DLBCL) and 0/10 women with ovarian DLBCL without concomitant uterine involvement. In multivariate analysis adjusted for other risk factors for SCNS, uterine involvement by DLBCL remained strongly associated with SCNS (Hazard ratio 14·13, 95% confidence interval 5·09-39·25, P < 0·001). Because involvement of the uterus by DLBCL appears to be associated with a high risk of SCNS, those patients should be considered for CNS staging and prophylaxis. However, more studies are needed to determine whether the increased risk of secondary CNS involvement also applies to women with localized reproductive organ DLBCL. [ABSTRACT FROM AUTHOR]

Summary The documented treatment‐induced excess mortality in Hodgkin lymphoma (HL) has spurred important treatment changes over recent decades. This study aimed to examine mortality among young HL patients treated with contemporary strategies, including historical data comparison. This nationwide study included 1348 HL patients, diagnosed in 1995–2015 and aged 15–40 at diagnosis. Among the patients, 66.5% had Ann Arbor stage I–II and 33.5% had stage III–IV disease. With a median follow‐up of 14.76 years, 139 deaths occurred, yielding a 5‐year overall survival of 94.6%. Older age, advanced disease, earlier treatment periods and extensive regimens were associated with higher overall mortality risk. The cumulative risk of HL‐related death showed an initial sharp rise, with a plateau at 5.3% 10‐year post‐diagnosis. Deaths due to cardiovascular or pulmonary diseases and second cancers initially had minimal risk, gradually reaching 1.2% and 2.0% at the 20‐year mark respectively. HL cases had a 7.5‐fold higher mortality hazard than the background population. This study suggests that contemporary HL treatment still poses excess mortality risk, but recent changes have notably reduced overall and cause‐specific mortality compared to earlier eras. Balancing treatment efficacy and toxicity remains crucial, but our findings highlight improved outcomes with modern treatment approaches. [ABSTRACT FROM AUTHOR]
