New treatment options in elderly patients with Diffuse Large B-cell Lymphoma

Impact of comorbidity on health-related quality of life in newly diagnosed patients with lymphoma or multiple myeloma: results from the PROFILES-registry

With the increasing prevalence of comorbidity in an ageing population, it is crucial to better understand the impact of comorbidity on health-related quality of life (HRQoL) after lymphoma or multiple myeloma (MM) diagnosis. We included 261 newly diagnosed patients (67% response rate) diagnosed with lymphoma or MM between October 2020 and March 2023 in a longitudinal survey. The European Organisation for Research and Treatment of Cancer (EORTC) questionnaires were used to measure generic and disease-specific HRQoL. Evidence-based guidelines for interpretation of the EORTC questionnaires were used to identify clinical importance. Patients were classified as having 'no comorbidity', 'mild comorbidity' (e.g. arthrosis or rheumatism), or 'moderate-severe comorbidity' (e.g. heart or lung disease), using the adapted self-administered comorbidity questionnaire. At diagnosis, the mean age was 64 years, 63% were male and 38% reported no comorbidity, 33% mild comorbidity, and 29% moderate-severe comorbidity. Patients with mild or moderate-severe comorbidity reported clinically relevant worse HRQoL at diagnosis than patients without comorbidity. One year post-diagnosis most outcomes showed clinically relevant improvement, irrespective of comorbidity. However, outcomes of physical functioning (β=-7.9, p < 0.05), global health status (β=-7.6, p < 0.05), bone pain (β = 8.1 to 9.1, p < 0.05), muscle/joint pain (β = 14.5 to 18.8, p < 0.01) and muscle weakness (β = 10.4 to 15.6, p < 0.05) improved less among those with comorbidity, and clinically relevant differences between comorbidity groups persisted over time. With clinically relevant worse HRQoL at diagnosis and less recovery of HRQoL during the first year after diagnosis in patients with comorbidity, consideration of both prognosis and HRQoL is important when making treatment decisions.

Appropriate Treatment Intensity for Diffuse Large B-Cell Lymphoma in the Older Population: A Review of the Literature

Most patients with diffuse large B-cell lymphoma (DLBCL) are >65 years of age, with the number of patients expected to increase in the coming years. A comprehensive geriatric assessment that carefully evaluates fitness status and comorbidities is essential for selecting the appropriate treatment intensity. Although generally healthy patients or those <80 years of age may benefit from standard immunochemotherapy, unfit/frail patients or patients >80 years old may require reduced-intensity chemotherapy or less-toxic drugs. Some new drugs are currently being tested as single or combined agents for first-line treatment, aiming to improve the outcomes of conventional chemotherapy. This review systematically collates and discusses the outcomes associated with the use of immunochemotherapy in older patients with DLBCL, as well as considering the impact of full-dose immunochemotherapy on quality of life in older and frail patients, summarizing the rationale for reduced dosing in the older population, and presenting recommendations for selecting patients likely to benefit from reduced dosing. If preliminary efficacy and safety data are confirmed in future clinical trials, non-chemotherapy-based immunotherapy approaches could become an alternative potentially curative option in frail patients and those >80 years of age with DLBCL.

Treatment patterns, healthcare resource utilization, and costs in Medicare patients with diffuse large B-cell lymphoma: a retrospective claims analysis (2015-2020)

AIMS

To understand treatment patterns, healthcare resource utilization (HCRU), and the economic burden of diffuse large B-cell lymphoma (DLBCL) in elderly adults in the US.

MATERIALS AND METHODS

This retrospective database analysis utilized US Centers for Medicare and Medicaid Services Medicare fee-for-service administrative claims data from 2015 to 2020 to describe DLBCL patient characteristics, treatment patterns, HCRU, and costs among patients aged ≥66 years. Patients were indexed at DLBCL diagnosis and required to have continuous enrollment from 12 months pre-index until 3 months post-index. HCRU and costs (USD 2022) are reported as per-patient per-month (PPPM) estimates.

RESULTS

A total of 11,893 patients received ≥1-line (L) therapy; 1,633 and 391 received ≥2 L and ≥3 L therapies, respectively. Median (Q1, Q3) age at 1 L, 2 L, and 3 L initiation, respectively, was 76 (71, 81), 77 (72, 82), and 77 (72, 82) years. The most common therapy was R-CHOP (70.9%) for 1 L and bendamustine ± rituximab for 2 L (18.7%) and 3 L (17.4%). CAR T was used by 14.8% of patients in 3 L. Overall, 39.6% (1 L), 42.1% (2 L), and 47.8% (3 L) of patients had all-cause hospitalizations. All-cause mean (median [Q1-Q3]) costs PPPM during each line were $22,060 ($20,121 [$16,676-$24,597]) in 1 L, $30,027 ($20,868 [$13,416-$31,016]) in 2 L, and $47,064 ($25,689 [$15,555-$44,149]) in 3 L, with increasing costs driven primarily by inpatient expenses. Total all-cause 3 L mean (median [Q1-Q3]) costs PPPM for patients with and without CAR T were $153,847 ($100,768 [$26,534-$253,630]) and $28,466 ($23,696 [$15,466-$39,107]), respectively.

CONCLUSIONS

No clear standard of care exists in 3 L therapy for older adults with relapsed/refractory DLBCL. The economic burden of DLBCL intensifies with each progressing line of therapy, thus underscoring the need for additional therapeutic options.

Feasibility of Quality of Life Assessment in Patients with Lymphoma Aged ≥80 Years Receiving Reduced-Intensity Chemotherapy: A Single-Institute Study

Quality of life (QOL) must be carefully monitored in older patients with lymphoma who are suitable for chemotherapy, but few reports have assessed QOL in older patients who received reduced-intensity chemotherapy. This study investigated QOL in patients with lymphoma aged ≥80 years to clarify the feasibility of such assessments following reduced-intensity chemotherapy. QOL was prospectively analyzed (using the QOL Questionnaire for Cancer Patients Treated with Anticancer Drugs (QOL-ACD)] and the SF-36®, a comprehensive survey of patient health) among 13 patients (seven women) aged ≥80 years with lymphoma who received reduced-intensity chemotherapy at 4-week intervals at Kyushu University Beppu Hospital between June 2022 and August 2023. Patients were assessed at baseline, in the middle of the protocol, at the end of the protocol, and 6 months after the end of the protocol. The overall response rate was 69%. Almost all severe adverse events (10 patients) occurred during early cycles (cycles 1-2). Common adverse events included hematological toxicities such as neutropenia (10 patients). The daily activity (p = 0.048) and social attitude (p = 0.027) scores of the QOL-ACD and the general health perception (p = 0.044) and social functioning (p = 0.030) scores of the SF-36® were significantly improved during and after chemotherapy. Reduced-dose chemotherapy, if implemented before treatment selection, might permit evaluations of QOL in older patients aged ≥80 years; further investigation is warranted.
