ABSTRACT
Lenalidomide maintenance (LM) has shown benefit in progression-free survival (PFS) and overall survival (OS) in clinical trials. LM is the recommended standard of care in patients with newly diagnosed multiple myeloma (MM) after high-dose melphalan and autologous stem cell transplantation (HDM-ASCT). In Denmark, LM has been approved and publicly funded for all patients treated with HDM-ASCT since June 2019. Patients with newly diagnosed MM treated with their first HDM-ASCT between June 2019 and March 2022 were included and followed until data cut-off in June 2023. To compare outcomes, a historical pre-LM cohort from the Danish MM Registry, consisting of 364 MM patients treated with HDM-ASCT between June 2015 and June 2019, was used. Among 364 patients treated with HDM-ASCT after June 2019, 22.3% received consolidation therapy and 3.7% underwent tandem HDM-ASCT. During follow-up, 297 patients (81.6%) initiated maintenance therapy, with 277 (76.1%) receiving LM. Overall, 145 patients (52.3%) discontinued LM most commonly due to toxicity 75 (51.7%), with fatigue (30.7%), cytopenia (25.3%), and neuropathy (17.3%) being the main reasons. In a 6-month landmark analysis, early discontinuation did not negatively impact PFS or OS. The LM cohort had similar PFS, and OS compared to the pre-LM cohort. The 3-year PFS and OS rates in the LM cohort were 61% and 86%, respectively, while the pre-LM cohort had a 3-year PFS of 55% and a 3-year OS of 89%. In conclusion, the introduction of LM as a nationwide treatment option in Denmark did not lead to improved clinical outcomes.
ABSTRACT
In this case report a 73-year-old male with liver-metastatic colon cancer was admitted to hospital due to severe abdominal pain merely four days after receiving chemotherapy including epidermal growth factor receptor inhibitors. An acute computed tomography revealed gas-filled liver metastases with two possible diagnoses of either a rapid tumour response resulting in tumour necrosis or severe bacterial infection involving liver metastases. Moreover, the patient had an anaerobic infection with Clostridium septicum, and despite relevant treatment he died within 12 hours after admission.

OBJECTIVE: The impact of body mass index (BMI) and body surface area (BSA) on survival in diffuse large B-cell lymphoma (DLBCL) is controversial. Recent studies show superior outcomes for overweight and obese patients. PATIENTS AND METHODS: A total of 653 R-CHOP(-like)-treated DLBCL patients were included in this retrospective cohort study. Patients, baseline clinicopathologic characteristics and treatment information were retrieved from the Danish Lymphoma Registry. Anthropometric measures were obtained from chemotherapy prescription charts. RESULTS: Underweight (BMI <18.5 kg/m2 ) was associated with significantly worse progression-free survival (PFS) for male patients only in sex-stratified analyses (HR 3.92, 95% CI: 1.57-9.75, P = 0.003, for males; HR 1.65, 95% CI: 0.90-3.02, P = 0.107, for females). In multivariate analyses, underweight was associated with worse PFS for both sexes (HR 5.34, 95% CI: 2.07-13.79, P = 0.001, for males; HR 2.14, 95% CI: 1.12-4.08, P = 0.021, for females). Similar results were obtained in analyses of overall survival. In crude analyses, BSA <1.8 m2 was associated with worse PFS for men and women (HR 1.65, 95% CI: 1.03-2.65, P = 0.039, for men; HR 1.62, 95% CI: 1.03-2.56, P = 0.037, for women). In multivariate analyses, however, these associations diminished. CONCLUSIONS: Our study demonstrates that underweight DLBCL patients have worse outcomes following R-CHOP as compared to normal as well as overweight patients.
