Hodgkin disease (1973-2002): long-term survival and cure fractions

Retrospective Multicenter Real-Life Study on the First-Line Treatment of Classical Hodgkin Lymphoma in Argentina

There are no data in Argentina on the response rates to first-line treatment of classical Hodgkin Lymphoma (cHL) outside clinical trials. A total of 498 patients from 7 public and private hospitals in Argentina were retrospectively examined. The median follow-up was 37.4 months (CI 95% 17.7–63.5). The median time from diagnosis to treatment was 22 days (IQR 14–42), which was significantly longer in public hospitals (49.3 (IC 95% 38.5–60.2) versus 32.5 (IC 95% 27–38); p = 0.0027). A total of 96.8% of patients were treated with ABVD.:84.3% achieved complete remission (CR) and 6.02% partial remission (PR), being the CR rate higher in private hospitals. End-of-treatment metabolic CR was achieved in 85.4% (n = 373). The interim PET scan was widely used in our cohort (70.5%; n = 351), but in only 23.3% (n = 116) was the treatment strategy response-adapted. The 5-year progression-free survival (PFS) was 76% (CI 95% 70–81). The 2 and 5-years-OS rates were 91% (CI 95% 88–94%) and 85% (CI 95% 80–89%), respectively. No differences in OS were found between public and private institutions (p = 0.27). This is one of the largest retrospective cHL cohorts reported. In Argentina ABVD is the chemotherapy regimen of choice and, although it is well tolerated, it is not exempt from toxicity. We showed that early initiation of treatment impacts the induction results. Although the use of PET scan is widespread, only a minority of patients was treated with respons- adapted strategies. The use of PET-guided treatment is strongly encouraged.

Ophthalmic Manifestations of Hodgkin Lymphoma: A Review

Background

Hodgkin lymphoma (HL) is a hematopoietic neoplasm characterized by cancerous Reed-Sternberg cells. In contrast to ophthalmic manifestations by non-HL that are well recognized, there is paucity of the literature as it relates to ophthalmic manifestation by HL. We performed a comprehensive review of published studies (case reports and small case series) to characterize the ophthalmic manifestations of HL.

Summary

Thirty patients were identified with ophthalmic manifestation of HL. Thirteen (43%) were male, and 14 (46%) were female (in 3 cases, sex was not specified). The median age at ophthalmic presentation was 27 years. Diagnosis of HL was made after ophthalmic manifestation in 10 (33%) cases, whereas 11 (36%) cases had a prior diagnosis of HL. Ophthalmic manifestations can be classified into 3 main groups; direct infiltration, inflammatory reaction, and paraneoplastic process. Seven cases had infiltration of the optic nerve. Uveal inflammatory reaction was reported in 21 cases. The presence of intraocular Reed-Sternberg cells had been confirmed in 1 case with granulomatous uveitis. Conjunctival and corneal reaction was seen in 3 cases. HL was in stage 2 or higher, with only 1 case with stage 1A (12 cases HL stage not specified). Seven cases (22%) died of HD, all were diagnosed with advanced lymphoma, and none was treated with chemotherapy.

Key Message

Ocular involvement in HL is extremely rare. A few cases of histopathologically confirmed optic nerve/tract infiltration are within the spectrum of CNS involvement by HL. Inflammatory uveitis is the most common ophthalmic association of HL. In the presence of prior known diagnosis of HL, restaging should be considered to exclude recurrence. Toxicity or adverse reaction to drugs used to treat HL may also contribute to ophthalmic involvement.

Global, regional, and national burden of Hodgkin lymphoma from 1990 to 2017: estimates from the 2017 Global Burden of Disease study

Background

Hodgkin lymphoma (HL) is an uncommon B cell lymphoma. We assessed the global, regional, and national burden of HL from 1990 to 2017, by gender, age, and social-demographic index (SDI).

Methods

Data on HL, including incidence, mortality, and disability adjusted life-years (DALY), from 1990 to 2017 were obtained from the 2017 Global Burden of Disease study. Estimated annual percentage changes (EAPCs) were calculated to assess incidence rate, mortality, and DALY trends.

Results

HL incidences increased by 38.66%, from 72,937 in 1990 to 101,133 in 2017, while the age-standardized incidence rate (ASIR) was relatively stable. ASIR decreased in the low SDI regions (EAPC = − 2.58; 95% CI, from − 2.66 to − 2.49) and was stable in the other four SDI regions. Incidence showed a bimodal distribution with peak values in patients aged 20–39 years and patients aged 60 years or higher. The number of death cases and DALYs were stable. The age-standardized death rate decreased by 2.36% (95% CI, from − 2.43% to − 2.30%) per year. The annual age-standardized DALY rate decreased by 2.29% (95% CI, from − 2.36% to − 2.21%). The incidence and mortality in male subjects was higher than that in female subjects. The incidence in male and female subjects aged 15–30 years old was close, whereas the biggest difference existed in patients aged < 10 years old and 45–75 years old between genders.

Conclusion

Globally, incidence of HL was stable, while mortality and DALY rate of HL had been decreasing from 1990 to 2017. Compared with lower and decreasing ASIR in the low SDI region, ASIR in the high SDI region was always high, indicating the need for HL treatment improvement and the establishment of more targeted and specific strategies in high SDI countries to reduce the incidence of HL.
