- When treating limited stage classical Hodgkin lymphoma (cHL), balancing treatment efficacy and toxicity is important. Toxicities after extended-field radiotherapy are well documented. Investigators have aimed at reducing toxicity without compromising efficacy, mainly by using combined modality treatment (CMT), i.e. chemotherapy and limited-field radiotherapy. In some clinical trials, radiotherapy has been omitted. We evaluated 364 patients with stage I-IIA cHL treated between 1999 and 2005. Patients were treated with two or four cycles of doxorubicin, bleomycin, vinblastine and dacarbazine (ABVD) according to presence of risk factors, followed by 30 Gy limited-field (reduced compared to involved-field) radiotherapy. After a median follow-up of 16 years for survival, freedom from progression at five and ten years was 93% and overall survival at 5 and 10 years was 98% and 96%, respectively. Only two relapses, out of 27, occurred after more than 5 years. There was no excess mortality compared to the general population. Of the analysed subgroups, only patients with progression within five years showed significant excess mortality. The absence of excess mortality questions the concept of omitting radiotherapy after short-term chemotherapy, a strategy that has been associated with an elevated risk of relapse but not yet with a proven reduced long-term excess mortality.

- Objective: Forty percent of Hodgkin lymphoma (HL) patients are older than 50years at diagnosis, a fact which is not commonly recognized. Older patients do significantly worse than younger patients and are rarely included in clinical trials.Methods: Using data from Swedish Cancer and Lymphoma Registries, we estimated relative survival ratios (RSRs) for 7997 HL patients (diagnosed 1973-2013; 45% 50years).Results: The 1-year RSRs (95% confidence interval; CI) for males aged 45-59, 60-69, 70-80, and 81years and over, diagnosed in 2013, were 0.95 (0.91-0.97), 0.88 (0.81-0.92), 0.74 (0.63-0.81), and 0.52 (0.35-0.67), respectively. The corresponding 1-year RSRs for females were 0.97 (0.94-0.98), 0.91 (0.85-0.95), 0.82 (0.73-0.88), and 0.66 (0.50-0.77). No improvements in 1-year of 5-year relative survival from 2000 to 2013 were observed for patients aged 45-59 or 60-69 but there were modest improvements for patients aged 70years and older. Importantly, we saw no changes in the distribution of disease or patient characteristics between 2000 and 2013.Conclusions: Elderly patients constitute a large group with clearly unmet medical needs. Our findings motivate a more active approach to including elderly patients in clinical trials. Our study provides a baseline for outcome comparison after the broader introduction of targeted drugs.

- Purpose With excellent cure rates for young patients with Hodgkin lymphoma (HL), there is an increasing number of female survivors of HL interested in becoming pregnant. Here, we report childbearing among contemporarily treated HL survivors in comparison with the general population. Material and Methods Using Swedish registers, 449 women (ages 18 to 40 years) diagnosed with HL between 1992 and 2009 and in remission 9 months after diagnosis were identified. Patients were age- and calendar-year-matched to 2,210 population comparators. Rates of first postdiagnosis childbirth were calculated. Hazard ratios (HRs) with 95% CIs were estimated for different follow-up periods using Cox regression. Cumulative probabilities of first childbirth were calculated in the presence of the competing risk of death or relapse. Results Twenty-two percent of relapse-free patients with HL had a child during follow-up, and first childbirth rates increased over time, from 40.2 per 1,000 person-years (1992 to 1997) to 69.7 per 1,000 person-years (2004 to 2009). For comparators, childbirth rates remained stable (70.1 per 1,000 person-years). Patients diagnosed between 2004 and 2009 had a cumulative probability of childbirth similar to comparators. Three years or more after diagnosis, no differences in childbirth rates were observed between patients and comparators, regardless of stage or treatment. Patients who received six to eight courses of bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone had a lower childbirth rate than comparators during the first 3 years (HR, 0.23; 95% CI, 0.06 to 0.94), as did patients who received six to eight courses of chemotherapy and radiotherapy (HR, 0.21; 95% CI, 0.07 to 0.65). Conclusion Childbearing potential among female survivors of HL has improved over time, and childbirth rates 3 years after diagnosis in contemporarily treated patients are, in the absence of relapse, similar to those in the general population, regardless of stage and treatment.

Pregnancy and the Risk of Relapse in Patients Diagnosed With Hodgkin Lymphoma

- PURPOSE: Many patients and clinicians are worried that pregnancy after the diagnosis of Hodgkin lymphoma (HL) may increase the risk of relapse despite a lack of empirical evidence to support such concerns. We investigated if an association exists between pregnancy and relapse in women with a diagnosis of HL.MATERIALS AND METHODS: Using Swedish healthcare registers combined with medical records, we included 449 women who received a diagnosis of HL between 1992 and 2009 and who were age 18 to 40 years at diagnosis. Follow-up started 6 months after diagnosis, when the patients' condition was assumed to be in remission. Pregnancy-associated relapse was defined as a relapse during pregnancy or within 5 years after delivery. Hazard ratios (HRs) with 95% CIs were estimated by using the Cox proportional hazards model.RESULTS: Among the 449 women, 144 (32%) became pregnant during follow-up. Overall, 47 relapses were recorded, of which one was a pregnancy-associated relapse. The adjusted HR for the comparison of the pregnancy-associated relapse rate to the non-pregnancy-associated relapse rate was 0.29 (95% CI, 0.04 to 2.18). The expected number of relapses in women with a recent pregnancy, given that they would experience the same relapse rate as that of women without a recent pregnancy, was 3.76; the observed-to-expected ratio was 0.27 (95% exact CI, 0.01 to 1.51).CONCLUSION: We found no evidence that a pregnancy after diagnosis increases the relapse rate among women whose HL is in remission. Survivors of HL need to consider a range of factors when deciding about future reproduction. However, given the results of this study, the risk of pregnancy-associated relapse does not need to be considered.

- While Hodgkin lymphoma (HL) survival has improved, treatment-related complications remain a concern. As a measure of treatment-related diseases of the circulatory system (DCS) we report excess incidence of DCS and absolute risks among HL patients diagnosed in the modern treatment era. From the Swedish Cancer Register, we identified all HL patients diagnosed 1985 through 2013, at ages 18-80 years. Excess incidence rate ratios (EIRRs) with 95% confidence intervals (CIs) comparing excess DCS incidence between calendar periods were estimated overall, and at 5 and 10 years after diagnosis using flexible parametric models. Model-based predictions were used to obtain probabilities of being diagnosed with DCS, in the presence of competing risks. During follow-up, 726 (16%) of the 4,479 HL patients experienced DCS. Overall, the excess DCS incidence was lower during all calendar periods compared to the first (2009-2013 vs. 1985-1988: EIRR = 0.63, 95% CI: 0.42-0.95). The 5- and 10-year excess incidence of DCS decreased between 1985 and 1994 for 25-year-olds (5-year-EIRR1994 = 0.32, 95% CI: 0.12-0.92) and 60-year-olds (5-year-EIRR1994 = 0.45, 95% CI: 0.24-0.88), but remained stable thereafter. No improvements were observed among 75-year-olds. The probability of excess DCS remained the same throughout the study period. In 2009, the percentage of patients aged 25, 60 and 75 experiencing excess DCS within 5 years was 3.4, 15.0 and 17.0% (males) and 2.3, 10.8 and 12.6% (females). Treatment-related incidence of DCS has declined since the mid-1980s, but more recent improvements are absent and an excess risk remains. Continued efforts towards less toxic treatments are warranted, alongside primary prevention strategies.
