    Abstract: 71 Background: Survivors of Hodgkin lymphoma (HL) are at risk for late adverse effects of treatment. The Dutch BETER consortium, consisting of healthcare providers, researchers and patient representatives, has set up survivorship care clinics where HL survivors are screened for late effects. Methods: In order to assess patient characteristics and clinical attendance rates, descriptive statistics were calculated for data on HL survivors who were invited to attend the BETER clinics in the University Medical Center Utrecht (UMCU) and Erasmus University Medical Center (EMC). Results: Overall 291 survivors were invited to attend one of the two BETER clinics. Median age at invitation was 46 years (interquartile range IQR: 40-55 years), median age at HL diagnosis 29 years (IQR: 22-37 years) and median time since diagnosis 16 years (IQR: 11-22 years). Survivors were referred to the BETER clinic by the general EMC/UMCU outpatient clinics where they were still under surveillance (42%) or invited by phone (37%) or letter (20%). While 79% of survivors responded to the invitation, only 53% of all patients actually visited the BETER clinic. Most common reasons to not attend were: undergoing surveillance or treatment for late effects elsewhere (91%) and unwillingness to attend (8%; e.g. due to financial or emotional burden). Ninety-eight% of survivors who were still under surveillance in EMC/UMCU hospitals attended the BETER clinic, as opposed to only 19% of survivors who were no longer under surveillance. Survivors initially invited by letter were more likely to attend (38%) than those who were first contacted by phone (11%). Age at invitation and age at HL diagnosis were similar in those who did and did not attend. Similar data for another 3 clinics are being collected and will be presented at the ASCO Survivorship Symposium. Conclusions: These preliminary data show that only half of HL survivors who were invited, attended a BETER clinic. Unfortunately, survivors who were no longer under medical surveillance were less likely to attend, especially when first contacted by phone. Future, more detailed, evaluation of (non-)attendance in more BETER clinics may reveal the need for additional implementation measures to improve the BETER survivorship care program.

    Abstract: Baseline metabolic tumor volume (MTV) is a promising biomarker in diffuse large B-cell lymphoma (DLBCL). Our aims were to determine the best statistical relationship between MTV and survival and to compare MTV with the International Prognostic Index (IPI) and its individual components to derive the best prognostic model. METHODS PET scans and clinical data were included from five published studies in newly diagnosed diffuse large B-cell lymphoma. Transformations of MTV were compared with the primary end points of 3-year progression-free survival (PFS) and overall survival (OS) to derive the best relationship for further analyses. MTV was compared with IPI categories and individual components to derive the best model. Patients were grouped into three groups for survival analysis using Kaplan-Meier analysis; 10% at highest risk, 30% intermediate risk, and 60% lowest risk, corresponding with expected clinical outcome. Validation of the best model was performed using four studies as a test set and the fifth study for validation and repeated five times. RESULTS The best relationship for MTV and survival was a linear spline model with one knot located at the median MTV value of 307.9 cm 3 . MTV was a better predictor than IPI for PFS and OS. The best model combined MTV with age as continuous variables and individual stage as I-IV. The MTV-age-stage model performed better than IPI and was also better at defining a high-risk group (3-year PFS 46.3% v 58.0% and 3-year OS 51.5% v 66.4% for the new model and IPI, respectively). A regression formula was derived to estimate individual patient survival probabilities. CONCLUSION A new prognostic index is proposed using MTV, age, and stage, which outperforms IPI and enables individualized estimates of patient outcome.

    Abstract: 8039 Background: During the last decades Hodgkin Lymphoma (HL) treatment changed towards less toxic chemotherapy schemes and smaller radiation fields. The impact of these changes on second cancer (SC) risk is still unknown. Methods: We calculated standardized incidence ratios (SIR), comparing SC risk after HL treatment with expected risk, based on cancer incidence in the general population, and compared SC risk between treatment modalities, accounting for competing events, in a large Dutch cohort comprising 3,390 5-years HL survivors, aged 15-51 years at HL treatment and diagnosed between 1965-2000. Results: The median follow-up was 18.2 years; 23% of the patients was followed ≥25 years. During follow-up 734 SCs and 92 third cancers (TC) occurred. The SIR for any SC was 4.5 (95% confidence interval (95%CI) 4.1-4.9). SC risk was still elevated after 35 years of follow-up (SIR 3.9; 95%CI 2.5-5.8) and cumulative incidence (CI) reached 47.1% (95%CI 43.6-50.5) at 40 years follow-up. For TCs the SIR was 5.5 (95%CI 4.4-6.9); the 20-year CI was 22.3% (95%CI 17.8-27.2). Risks of NHL and leukemia strongly decreased in more recent treatment periods (P-trend 〈 0.001). The CI of solid tumors (ST) between 5-19 years after HL treatment did not differ for patients treated between 1965-1979, 1980-1989 or 1990-2000 (P=0.21; 19-year CI 9.1%, 11.6% and 11.4%, respectively). Radiotherapy (RT) above the diaphragm increased risk of STs above the diaphragm (hazard ratio (HR) 2.4, P 〈 0.001), while subdiaphragmatic RT was associated with a 1.7-fold increased HR of a subdiaphragmatic ST (P=0.001). An incomplete mantle field was associated with significantly lower breast cancer (BC) risk (hazard ratio (HR) 0.4, 95%CI 0.2-0.8). A cumulative procarbazine dose 〉 4.2 g/m 2 yielded a 1.3-fold increased HR (95%CI 1.0-1.7) for non-breast STs and a 2-fold (95%CI 1.2-3.1) increased HR for gastrointestinal STs, but was associated with a strongly decreased BC risk (HR 0.3, 95%CI 0.2-0.6). Conclusions: SC risk after HL has decreased with treatment changes over the last decades, due to strongly decreasing risk of leukemia and NHL. Smaller radiation fields and procarbazine doses 〉 4.2 g/m 2 are associated with lower breast cancer risk, while high procarbazine doses increase risk of gastrointestinal STs.

    Abstract: Combined-modality treatment is standard treatment for patients with clinical stage I/II Hodgkin lymphoma (HL). We hypothesized that an early positron emission tomography (PET) scan could be used to adapt treatment. Therefore, we started the randomized EORTC/LYSA/FIL Intergroup H10 trial evaluating whether involved-node radiotherapy (IN-RT) could be omitted without compromising progression-free survival in patients attaining a negative early PET scan after two cycles of ABVD (doxorubicin, bleomycin, vinblastine, and dacarbazine) as compared with standard combined-modality treatment. Patients and Methods Patients age 15 to 70 years with untreated clinical stage I/II HL were eligible. Here we report the clinical outcome of the preplanned interim futility analysis scheduled to occur after documentation of 34 events in the early PET–negative group. Because testing for futility in this noninferiority trial corresponds to testing the hypothesis of no difference, a one-sided superiority test was conducted. Results The analysis included 1,137 patients. In the favorable subgroup, 85.8% had a negative early PET scan (standard arm, one event v experimental arm, nine events). In the unfavorable subgroup, 74.8% had a negative early PET scan (standard arm, seven events v experimental arm, 16 events). The independent data monitoring committee concluded it was unlikely that we would show noninferiority in the final results for the experimental arm and advised stopping random assignment for early PET–negative patients. Conclusion On the basis of this analysis, combined-modality treatment resulted in fewer early progressions in clinical stage I/II HL, although early outcome was excellent in both arms. The final analysis will reveal whether this finding is maintained over time.

    Abstract: Previous efforts to predict absolute risk of treatment-related cardiovascular diseases (CVDs) have mostly focused on childhood cancer survivors. We aimed to develop prediction models for risk of coronary heart disease (CHD) and heart failure (HF) for survivors of adolescent/adult Hodgkin lymphoma (HL). METHODS For model development, we used a multicenter cohort including 1,433 5-year HL survivors treated between 1965 and 2000 and age 18-50 years at HL diagnosis, with complete data on administered chemotherapy regimens, radiotherapy volumes and doses, and cardiovascular follow-up. Using cause-specific hazard models, covariate-adjusted cumulative incidences for CHD and HF were estimated in the presence of competing risks of death because of other causes than CHD and HF. Age at HL diagnosis, sex, smoking status, radiotherapy, and anthracycline treatment were included as predictors. External validation for the CHD model was performed using a Canadian cohort of 708 HL survivors treated between 1988 and 2004 and age 18-50 years at HL diagnosis. RESULTS After a median follow-up of 24 years, 341 survivors had developed CHD and 102 had HF. We were able to predict CHD and HF risk at 20 and 30 years after treatment with moderate to good overall calibration and moderate discrimination (areas under the curve: 0.68-0.74), which was confirmed by external validation for the CHD model (areas under the curve: 0.73-0.74). On the basis of our model including prescribed mediastinal radiation dose, 30-year risks ranged from 4% to 78% for CHD and 3% to 46% for HF, depending on risk factors. CONCLUSION We developed and validated prediction models for CHD and HF with good overall calibration and moderate discrimination. These models can be used to identify HL survivors who might benefit from targeted screening for CVD and early treatment for CVD risk factors.

    Abstract: 40 Background: The risk of developing gastrointestinal (GI) cancer is increased in Hodgkin lymphoma survivors. This study aims to compare overall survival of GI cancer in Hodgkin lymphoma survivors with survival of first primary GI cancer patients. Methods: This cohort study compared overall survival of GI cancer patients in a Hodgkin lymphoma survivor population (HL-GI (n = 92) including esophageal (n = 25), gastric (n = 31), small intestinal (n = 2), colorectal cancer (n = 34)) with survival of a population-based cohort of first primary GI cancer patients (GI-1, n = 911) which was generated by individual matching of the 92 cases, based on tumor location, gender, age and year at diagnosis. Clinical characteristics were compared by Chi square tests. Cox regression was used for multivariable survival analysis (corrected for age, gender, and clinicopathological characteristics related to the GI tumor). Results: When comparing HL-GI and GI-1 patients, no differences in tumor stage, grade of differentiation or frequency of surgery were found. HL-GI patients were less frequently treated for their GI tumor with radiation therapy (7% vs. 24% in GI-1 patients, p 〈 0.001) or chemotherapy (28% vs. 41%, p = 0.02). Overall 5-year and 20-year survival of HL-GI patients and GI-1 patients was non-significantly lower (28% vs. 38%, p = 0.13 and 19% vs. 29%, p = 0.06, respectively). This result was confirmed multivariably (5-year survival, p = 0.33, 20-year survival, p = 0.14). Also, for esophageal, gastric and colorectal cancer separately, no differences in overall survival were found between HL-GI patients and GI-1 patients. Conclusions: Long-term overall survival of GI cancer patients is similar in Hodgkin lymphoma survivors and first primary GI cancer patients. HL-GI patients did however receive less treatment with radiation therapy or chemotherapy. These treatments may not have been recommended due to prior Hodgkin lymphoma treatment or comorbidity. As risks of other causes of mortality are also increased in Hodgkin lymphoma survivors, the relatively good survival in this population is remarkable.

    Abstract: Immunochemotherapy with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) has become standard of care for patients with diffuse large B-cell lymphoma (DLBCL). This randomized trial assessed whether rituximab intensification during the first 4 cycles of R-CHOP could improve the outcome of these patients compared with standard R-CHOP. PATIENTS AND METHODS A total of 574 patients with DLBCL age 18 to 80 years were randomly assigned to induction therapy with 6 or 8 cycles of R-CHOP-14 with (RR-CHOP-14) or without (R-CHOP-14) intensification of rituximab in the first 4 cycles. The primary end point was complete remission (CR) on induction. Analyses were performed by intention to treat. RESULTS CR was achieved in 254 (89%) of 286 patients in the R-CHOP-14 arm and 249 (86%) of 288 patients in the RR-CHOP-14 arm (hazard ratio [HR], 0.82; 95% CI, 0.50 to 1.36; P = .44). After a median follow-up of 92 months (range, 1-131 months), 3-year failure-free survival was 74% (95% CI, 68% to 78%) in the R-CHOP-14 arm versus 69% (95% CI, 63% to 74%) in the RR-CHOP-14 arm (HR, 1.26; 95% CI, 0.98 to 1.61; P = .07). Progression-free survival at 3 years was 74% (95% CI, 69% to 79%) in the R-CHOP-14 arm versus 71% (95% CI, 66% to 76%) in the RR-CHOP-14 arm (HR, 1.20; 95% CI, 0.94 to 1.55; P = .15). Overall survival at 3 years was 81% (95% CI, 76% to 85%) in the R-CHOP-14 arm versus 76% (95% CI, 70% to 80%) in the RR-CHOP-14 arm (HR, 1.27; 95% CI, 0.97 to 1.67; P = .09). Patients between ages 66 and 80 years experienced significantly more toxicity during the first 4 cycles in the RR-CHOP-14 arm, especially neutropenia and infections. CONCLUSION Early rituximab intensification during R-CHOP-14 does not improve outcome in patients with untreated DLBCL.

    Abstract: TPS3149 Background: With the emergence of large-scale genetic tumor profiling and the increasing availability of approved targeted therapies, precision medicine has become crucial in cancer treatment. However, for many cancers the relative contribution of either tumor type or genetic aberration to drug sensitivity often remains unknown. Since drug access is generally limited to the on-label indication and outcome of off-label use is not systematically collected in clinical practice, innovative trials facilitating drug access, whilst systematically analyzing treatment outcomes, are urgently needed. Methods: The Drug Rediscovery Protocol (DRUP) is an ongoing, prospective, non-randomized, multi-drug, and pan-cancer trial, in which patients with advanced cancer, who have exhausted all standard of care treatment options, are treated with either targeted or immunotherapy matched to their genetic tumor profile. All submitted patients are reviewed and enrolled in multiple parallel cohorts, preceded by a baseline tumor biopsy for whole genome sequencing to confirm previously identified variants and for exploratory biomarker analyses. Each cohort is defined by a study drug, histologic tumor type, and molecular tumor profile. Efficacy is analyzed per cohort: 8 patients in stage I and 16 more in stage II if ≥ 1 response is observed in the first stage. Primary endpoints include objective response rate, stable disease at 16 weeks, and grade ≥3 adverse events. Since the start of recruitment in September 2016, 870 patients have been submitted for review and 365 patients (42%) have started treatment in one of 101 opened cohorts. Eight cohorts have graduated to the second stage, two cohorts completed accrual in either their first or second stage, and one cohort was closed due to a registered indication. Twenty-two different study treatments (i.e. immunotherapy, monoclonal antibodies, and PARP/small molecule inhibitors), provided by 11 different pharmaceutical companies, are currently available in DRUP. Data sharing with similar trials such as TAPUR and CAPTUR enables to achieve completion of slow accruing cohorts and affirm conclusions. Clinical trial information: NCT02925234.

    Abstract: e16526 Background: CT-induced FN can result in reduced CT delivery, unplanned hospitalizations, and increased mortality risk. Changes in clinical practice warrant investigation of current resource use and economic cost of FN; therefore we studied FN-related HCU among BC and NHL pts. Methods: Data from incident adult cancer pts with a primary hospital discharge diagnosis for BC or NHL from 1998–2007 were obtained from the PHARMO Record Linkage System, including pharmacy, hospital and clinical lab data. Eligible pts had ≥12 months medical history available and received CT ≤6 months after cancer diagnosis. Pts developing FN ≤6 months after first CT (“FN pts”) were matched 1:2 on gender, birth year, and CT regimen to pts without FN (“non FN pts”). HCU data (hospitalizations, medical procedures, drug use [number dispensed]) was tallied from entry date (date of FN or matched date for non FN pts) for up to 3 months. Statistics are descriptive with crude odds ratios (OR). Results: 80/1,033 BC pts (8%) developed FN (all were matched). 95/486 NHL pts (20%) developed FN (89 were matched). More FN than non FN pts were hospitalized in the 1st month after the entry date: BC 73% vs 14% (OR=23.0 [95%CI 8.3-63.7] ); NHL 78% vs 33% (OR=7.6 [3.9-15.1]). These differences were mainly due to FN-related hospitalizations (BC 55% vs 1%, NHL 47% vs 4%). FN pts also had a longer mean length of stay per all-cause hospitalization: BC 4.6 vs 1.9 days; NHL 10.1 vs 3.0 days. In the 1 st month after entry date, the mean number of total drugs dispensed per patient was higher in FN pts than non FN pts (BC 5.8 vs 3.1, NHL 8.5 vs 3.6); use of anti-infectious agents was higher (BC 99% vs 11%, NHL 96% vs 20%), as was number of other non-CT drugs (including corticosteroids, drugs for acid related disorders, laxatives, psycholeptics, analgesics, antithrombotics, and diuretics). More FN than non FN pts had medical procedures (BC 14% vs 3%, NHL 13% vs 8%). HCU differences between FN and non FN pts were maintained after 3 months. Conclusions: This study confirms the high resource utilization currently associated with FN, based on BC and NHL pt data from the Netherlands. Reduction of FN may improve quality of life and save resources.
