- Previous studies concerning reproductive patterns among non-Hodgkin lymphoma (NHL) survivors are scarce and those available have reported conflicting results. Treatment regimens vary considerably between aggressive and indolent NHL and studies of reproductive patterns by subtypes are warranted. In this matched cohort study, we identified all NHL patients aged 18-40 years and diagnosed between 2000 and 2018 from the Swedish and Danish lymphoma registers, and the clinical database at Oslo University Hospital (n = 2090). Population comparators were matched on sex, birth year and country (n = 19 427). Hazard ratios (HRs) were estimated using Cox regression. Males and females diagnosed with aggressive lymphoma subtypes had lower childbirth rates (HRfemale: 0.43, 95% CI: 0.31-0.59, HRmale: 0.61, 95% CI: 0.47-0.78) than comparators during the first 3 years after diagnosis. For indolent lymphomas, childbirth rates were not significantly different from comparators (HRfemale: 0.71, 95% CI: 0.48-1.04, HRmale: 0.94, 95% CI: 0.70-1.27) during the same period. Childbirth rates reached those of comparators for all subtypes after 3 years but the cumulative incidence of childbirths was decreased throughout the 10-year follow-up for aggressive NHL. Children of NHL patients were more likely to be born following assisted reproductive technology than those of comparators, except for male indolent lymphoma patients. In conclusion, fertility counselling is particularly important for patients with aggressive NHL.

- BACKGROUND We tested interim positron-emission tomography-computed tomography (PET-CT) as a measure of early response to chemotherapy in order to guide treatment for patients with advanced Hodgkin's lymphoma. METHODS Patients with newly diagnosed advanced classic Hodgkin's lymphoma underwent a baseline PET-CT scan, received two cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) chemotherapy, and then underwent an interim PET-CT scan. Images were centrally reviewed with the use of a 5-point scale for PET findings. Patients with negative PET findings after two cycles were randomly assigned to continue ABVD (ABVD group) or omit bleomycin (AVD group) in cycles 3 through 6. Those with positive PET findings after two cycles received BEACOPP (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisone). Radiotherapy was not recommended for patients with negative findings on interim scans. The primary outcome was the difference in the 3-year progression-free survival rate between randomized groups, a noninferiority comparison to exclude a difference of 5 or more percentage points. RESULTS A total of 1214 patients were registered; 937 of the 1119 patients (83.7%) who underwent an interim PET-CT scan according to protocol had negative findings. With a median follow-up of 41 months, the 3-year progression-free survival rate and overall survival rate in the ABVD group were 85.7% (95% confidence interval [CI], 82.1 to 88.6) and 97.2% (95% CI, 95.1 to 98.4), respectively; the corresponding rates in the AVD group were 84.4% (95% CI, 80.7 to 87.5) and 97.6% (95% CI, 95.6 to 98.7). The absolute difference in the 3-year progression-free survival rate (ABVD minus AVD) was 1.6 percentage points (95% CI, -3.2 to 5.3). Respiratory adverse events were more severe in the ABVD group than in the AVD group. BEACOPP was given to the 172 patients with positive findings on the interim scan, and 74.4% had negative findings on a third PET-CT scan; the 3-year progression-free survival rate was 67.5% and the overall survival rate 87.8%. A total of 62 patients died during the trial (24 from Hodgkin's lymphoma), for a 3-year progression-free survival rate of 82.6% and an overall survival rate of 95.8%. CONCLUSIONS Although the results fall just short of the specified noninferiority margin, the omission of bleomycin from the ABVD regimen after negative findings on interim PET resulted in a lower incidence of pulmonary toxic effects than with continued ABVD but not significantly lower efficacy.

- PurposePatients diagnosed with advanced-stage Hodgkin lymphoma (aHL) have historically been risk-stratified using the International Prognostic Score (IPS). This study investigated if a machine learning (ML) approach could outperform existing models when it comes to predicting overall survival (OS) and progression-free survival (PFS).Patients and MethodsThis study used patient data from the Danish National Lymphoma Register for model development (development cohort). The ML model was developed using stacking, which combines several predictive survival models (Cox proportional hazard, flexible parametric model, IPS, principal component, penalized regression) into a single model, and was compared with two versions of IPS (IPS-3 and IPS-7) and the newly developed aHL international prognostic index (A-HIPI). Internal model validation was performed using nested cross-validation, and external validation was performed using patient data from the Swedish Lymphoma Register and Cancer Registry of Norway (validation cohort).ResultsIn total, 707 and 760 patients with aHL were included in the development and validation cohorts, respectively. Examining model performance for OS in the development cohort, the concordance index (C-index) for the ML model, IPS-7, IPS-3, and A-HIPI was found to be 0.789, 0.608, 0.650, and 0.768, respectively. The corresponding estimates in the validation cohort were 0.749, 0.700, 0.663, and 0.741. For PFS, the ML model achieved the highest C-index in both cohorts (0.665 in the development cohort and 0.691 in the validation cohort). The time-varying AUCs for both the ML model and the A-HIPI were consistently higher in both cohorts compared with the IPS models within the first 5 years after diagnosis.ConclusionThe new prognostic model for aHL on the basis of ML techniques demonstrated a substantial improvement compared with the IPS models, but yielded a limited improvement in predictive performance compared with the A-HIPI.

- Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.We analyzed long-term results of the response-adapted trial for adult patients with advanced-stage Hodgkin lymphoma. The aim was to confirm noninferiority of treatment de-escalation by omission of bleomycin from doxorubicin, bleomycin, vinblastine, and dacarbazine (ABVD) for interim fluorodeoxyglucose positron emission tomography (iPET)–negative patients and assess efficacy and long-term safety for iPET-positive patients who underwent treatment intensification with escalated bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, and prednisolone (BEACOPP/BEACOPP14). The median follow-up is 7.3 years. For all patients, the 7-year progression-free survival (PFS) and overall survival (OS) are 78.2% (95% CI, 75.6 to 80.5) and 91.6% (95% CI, 89.7 to 93.2), respectively. The 1.3% difference in 3-year PFS (95% CI, –3.0 to 4.7) between ABVD and doxorubicin, vinblastine, and dacarbazine (AVD) now falls within the predefined noninferiority margin. Among 172 patients with positive iPET, the 7-year PFS was 65.9% (95% CI, 58.1 to 72.6) and the 7-year OS was 83.2% (95% CI, 76.2 to 88.3). The cumulative incidence of second malignancies at 7 years was 5.5% (95% CI, 4.0 to 7.5) for those receiving ABVD/AVD and 2.5% (95% CI, 0.8 to 7.7) for those escalated to BEACOPP. With extended follow-up, these results confirm noninferiority of treatment de-escalation after a negative iPET. Escalation with BEACOPP for iPET-positive patients is effective and safe, with no increase in second malignancies.

- Patients and Methods: From May 2007 to October 2010, 66 newly diagnosed primary central nervous system lymphoma (PCNSL) patients (M/F ratio 1:1) were enrolled. Younger patients (≤65 yrs; N=39) received 6 three-weekly cycles of chemotherapy consisting of: high-dose (HD)-methotrexate (MTX) (cycles 1, 2, 4 and 5), HD-cytosine arabinoside (AraC) (cycles 3 and 6) in addition to Rituximab (cycle 1 only), ifosfamide (cycles 1 and 4), cyclophosphamide (cycles 2 and 5), vincristine (cycles 2 and 5), vindesine (cycles 3 and 6), and dexamethasone (all 6 cycles). Depocyte® was delivered intratechally during the HD-MTX cycles. Elderly patients (66-75 yrs; N=27) received an identical Rituximab-containing 1st cycle. Cyclophosphamide and ifosfamide were replaced by temozolamide (cycles 2 to 6), which was also given as maintenance in patients with chemosensitive disease, and vincristine was omitted. No radiotherapy was given. Response was determined after the 2nd, 4th and 6thchemotherapy cycle by cerebral MRI and assessed according to International Primary CNS Lymphoma Coordinating Group criteria. The primary endpoint was overall survival (OS), secondary endpoints were progression-free survival (PFS), overall response rate (ORR), systemic toxicity and neurotoxicity assessed as Mini Mental State Examination (MMSE) and Functional Independence Measure (FIM). Results: The median age was 64 yrs overall, 55 yrs (range 40-65) for younger and 70 yrs (range 66-75 years) for elderly patients. In 56 patients, the International Extranodal Lymphoma Study Group prognostic score was: 0-1 (N=5), 2-3 (N=36) and 4-5 (N=15). In the remaining 10 patients, lumbar puncture was not performed in five and spinal fluid protein concentration not reported in additional five cases. Response assessment after completion of induction treatment was performed in 43 out of 66 patients and showed complete remission (CR/CRu) in 30 patients, partial remission (PR) in 5 and progressive disease (PD) in 8. The ORR was 53 %. In 23 patients, response could not be evaluated due to early progression (n=8), toxic death (n=4), poor performance (n=3), neurotoxicity (n=5), or other causes (n=3). Of the 27 elderly patients, 15 continued to maintenance therapy. Of these, 14 have completed the maintenance schedule. Remission status at month 3 was CR in 13 and PD in 1 patient. With a median follow-up of 11.1 months (range 0.6-40.2) the 3-yr OS was 54.6% with no significant difference between younger and elderly patients (56.4% vs 51.9% respectively, p=0.32). The 3-yr PFS was 35.1% (32.9% in younger and 38.2 % in elderly patients; p=0.96). There were four septic deaths. Grade 3-4 hematological toxicity was seen in 79 % of the patients. Arachnoditis-like symptoms occurred in 13 patients. In all but two patients, the symptoms resolved within less than a week. MMSE and FIM were recorded both before and after therapy in 32 patients. Scores improved in 18 and 20 patients, respectively. Conclusion: In conclusion, the schedule applied in the present study led to a 3 yr PFS of 35%. Surprisingly, no significant outcome difference was found between the younger and the elderly patients. The majority of treatment failures were due to early progressive disease under induction therapy. Although the follow-up of our study is short, de-escalation of induction treatment intensity by introduction of a less toxic agent as temozolomide, and its subsequent use in a maintenance schedule may explain a possible survival benefit of this strategy in elderly patients. Disclosures: No relevant conflicts of interest to declare.
