Cost-effectiveness analyses are required for therapies within Canada’s universal healthcare system, leading to delays relative to U.S. healthcare. Patients with Hodgkin lymphoma (HL) generally have an excellent prognosis, but those who relapse after or are ineligible for transplant benefit from novel therapies, including brentuximab vedotin (BV). BV was FDA-approved in 2011 but not Canadian-funded until 2014. To assess the impact of access delays, we compared changes in survival for U.S. (by insurer) and Canadian patients in periods pre/post-U.S. approval. Patients were 16–64 years, diagnosed with HL in 2007–2010 (Period 1) and 2011–2014 (Period 2) from the U.S. SEER and Canadian Cancer Registries. Approval date (surrogate) was utilized as therapy was unavailable in registries. Kaplan-Meier survival curves and adjusted Cox regression models compared survival between periods by insurance category. Among 12,003 U.S. and 4210 Canadian patients, survival was better in U.S. patients (adjusted hazard ratio (aHR) 0.87 (95%CI 0.77–0.98)) between periods; improvement in Canadian patients (aHR 0.84 (95%CI 0.69–1.03) was similar but non-significant. Comparisons between insurers showed survival was significantly worse for U.S. uninsured and Medicaid vs. U.S. privately insured and Canadian patients. Given the increasingly complex nature of oncologic funding, this merits further investigation to ensure equity in access to therapy developments.

Current studies describing younger children with Hodgkin lymphoma are limited by geographical region, small sample sizes and variable age groups. Although published data is lacking, there appears to be a trend toward a higher male to female ratio and a higher proportion of mixed cellularity subtype when compared to older cohorts. We performed a retrospective multicenter study utilizing the Pediatric Health Information System® database to evaluate patients aged 0–39 years with Hodgkin lymphoma. We identified 3,034 unique patients who met inclusion criteria. Younger age groups had a larger proportion of males, Hispanic/Latino ethnicity, and mixed cellularity subtype. Treatment-related complications, including mucositis, pain, bacterial infections, and thrombosis, were documented more frequently in older cohorts. We also found significant age-related differences in medical management. This study is the largest study evaluating age-related differences in patients with Hodgkin lymphomaand the first study to evaluate for differences in complicationsand supportive care management.

Introduction. In rare cases, chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma may transform into Hodgkin lymphoma, with about a hundred cases reported in the literature so far. We present a case of the Hodgkin variant of Richter transformation. Case report. After a oneyear watch and wait period, a 60-year-old male with CLL developed B symptoms, generalized lymphadenopathy, and splenomegaly. Upon initial staging (Binet B/Rai 3), he was started on fludarabine, cyclophosphamide, and rituximab (FCR) regimen. After the third cycle of treatment, the rightsided axillary lymphadenopathy persisted and became painful, while the dimensions of the remaining organs affected by the disease decreased. Upon the finalization of the final sixth FCR cycle, the painful right-sided axillary lymphadenopathy persisted (though partially decreasing in size), with the development of local redness and swelling. A biopsy of the residual axillary node was performed, which revealed disease transformation into Hodgkin lymphoma. Upon multislice computed tomography-based s taging ( IV E c linical stage) and prognostic assessment (unfavorable prognosis), it was decided that the treatment be continued with doxorubicin, vinblastine, dacarbazine (AVD) regimen. The presented patient died two months after the diagnosis of Hodgkin transformation (HT) was established during the initial cycle of AVD. Conclusion. Although CLL is an indolent malignancy, in rare cases of HT, the prognosis is largely dismal. The available treatment strategies demonstrate suboptimal results, although novel immunotherapies may change the landscape of HT therapy in the near future. [ABSTRACT FROM AUTHOR]
