AbstractThymus and activation-regulated chemokine (TARC) is expressed on Reed-Sternberg cells of patients with classical Hodgkin lymphoma (HL) and may serve as a marker in response assessment. In our study, we correlated serum TARC levels with early response to treatment measured by PET/CT in 19 newly diagnosed patients with HL who received ABVD (Adriblastin, Bleomycin, Vinblastine, Dacarbazine) regimen. Finally, 17 patients were analyzed and six of them (35%) achieved PET/CT negativity defined as Deauville (D) 1 or 2 after 2 cycles of ABVD; 11 pts (65%) had D3 on PET/CT. None of the patients presented D 4/5. Median serum TARC levels at diagnosis were significantly higher when compared with healthy controls: 5718 pg/ml vs 76.1 pg/ml (p < 0.001). All study patients were treated with ABVD regimen and there was a significant decrease of baseline serum TARC levels after 2 cycles of therapy. No significant difference of baseline serum TARC levels was demonstrated between patients with D1/2 and D3 whereas levels were significantly decreased after 2 cycles of ABVD in patients D1/2 vs D3; p = 0.049. There was a tendency to higher baseline serum TARC levels in patients with an increased LDH (lactate dehydrogenase) activity (p = 0.08) and in those who progressed when compared with those who maintained response (p = 0.09). Serum TARC levels decrease after chemotherapy and may serve as a marker of response assessment.

Early Response Assessment

Although patients with advanced-stage classic Hodgkin lymphoma have excellent outcomes with contemporary therapy, the outcomes of patients with refractory disease is suboptimal. Identification of these high-risk patients at diagnosis is challenging as the differences in outcomes using clinical criteria are less marked using current modern therapy. Data suggest that an interim PET-CT may be a powerful tool in risk-stratifying patients. Retrospective studies show that a negative interim PET-CT after two to four cycles of ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) is predictive of favorable outcome independent of IPS score. Currently, there are several ongoing trials that aim to determine whether early-response assessment can be used to select patients who might benefit from modifications of subsequent therapy, either by intensifying or abbreviating regimens and/or omitting radiotherapy with promising early results. Longer follow-up is required to assess whether this strategy impacts overall survival (OS). Herein, we review the results of recent trials using interim PET-CT-based adaptive design in the treatment of advanced HL.

TPS7567 Background: High risk for relapse is observed in cHL patients (pts) with SER to initial chemotherapy and organ toxicities may be higher following dose intensification. Methods: The phase 2 KEYNOTE-667 study will enroll 440 pts aged 3 to 17 (children) or 18 to 25 years (young adults) with newly diagnosed, confirmed stage IA, IB, or IIA cHL without bulky disease (Group 1 [low-risk]) or stage IIEB, IIIEA, IIIEB, IIIB, IVA, or IVB cHL (Group 2 [high-risk]); measurable disease; and performance status per Lansky Play-Performance Scale ≥50 (age ≤16 years) or Karnofsky score ≥50 (age >16 years). Pts will receive induction with doxorubicin, bleomycin, vinblastine, dacarbazine (ABVD; Group 1) or vincristine, etoposide/etoposide phosphate, prednisone/prednisolone, doxorubicin (OEPA; Group 2) for 2 cycles, then early response assessment by PET/CT/MRI. Pts with rapid early response (Deauville score 1-3) will receive standard therapy. Pts with SER (Deauville score 4-5) will receive consolidation with pembro 2 mg/kg Q3W up to 200 mg (children) or 200 mg Q3W (young adults) plus 2 cycles AVD (Group 1) or 4 cycles cyclophosphamide, vincristine, prednisone/prednisolone, dacarbazine (COPDAC-28; Group 2). PET/CT for late response assessment (LRA) will be performed after consolidation. After LRA, Group 1 pts with SER and Group 2 pts with Deauville score 4-5 will receive radiotherapy (RT). All pts will receive maintenance with pembro Q3W concomitantly with RT. Pembro will continue up to 17 administrations, with an option to stop after 24 weeks due to CR, or until progression, unacceptable toxicity, or withdrawal. The primary endpoint is ORR per Cheson 2007 IWG criteria by group in SER pts. Secondary endpoints are SERs with PET negativity after consolidation, 2-yr event-free survival (EFS), OS, and RT frequency and details by group, RERs with PET negativity after ABVD induction, 3-yr EFS by investigator, and OS by risk group, and serum TARC levels at screening in SERs by risk group. ORR with 95% CI will be estimated by Clopper-Pearson method. EFS and OS will be estimated by Kaplan-Meier method. Safety will be assessed in all treated pts. Clinical trial information: NCT03407144.

AbstractTo compare FDG-PET/unenhanced MRI and FDG-PET/diagnostic CT in detecting infiltration in patients with newly diagnosed Hodgkin lymphoma (HL). The endpoint was equivalence between PET/MRI and PET/CT in correctly defining the revised Ann Arbor staging system. Seventy consecutive patients with classical-HL were prospectively investigated for nodal and extra-nodal involvement during pretreatment staging with same-day PET/CT and PET/MRI. Findings indicative of malignancy with the imaging procedures were regarded as lymphoma infiltration; in case of discrepancy, positive-biopsy and/or response to treatment were evidenced as lymphoma. Sixty of the 70 (86%) patients were evaluable having completed the staging program. Disease staging based on either PET/MRI or PET/CT was correct for 54 of the 60 patients (90% vs. 90%), with difference between proportions of 0.0 (95% CI, −9 to 9%; P=0.034 for the equivalence test). As compared with reference standard, invasion of lymph nodes was identified with PET/MRI in 100% and with PET/CT in 100%, of the spleen with PET/MRI in 66% and PET/CT in 55%, of the lung with PET/MRI in 60% and PET/CT in 100%, of the liver with PET/MRI in 67% and PET/CT in 100%, and of the bone with PET/MRI in 100% and PET/CT in 50%. The only statistically significant difference between PET/MRI and PET/CT was observed in bony infiltration detection rates. For PET/CT, iodinate contrast medium infusions’ average was 86 mL, and exposure to ionizing radiation was estimated to be 4-fold higher than PET/MRI. PET/MRI is a promising safe new alternative in the care of patients with HL.

AbstractMetabolic reprogramming is one of the hallmarks of cancer and includes the Warburg effect, which is exhibited by many tumours. This can be exploited by positron emission tomography (PET) as part of routine clinical cancer imaging. However, an emerging and alternative method to detect altered metabolism is carbon-13 magnetic resonance imaging (MRI) following injection of hyperpolarised [1-13C]pyruvate. The technique increases the signal-to-noise ratio for the detection of hyperpolarised 13C-labelled metabolites by several orders of magnitude and facilitates the dynamic, noninvasive imaging of the exchange of 13C-pyruvate to 13C-lactate over time. The method has produced promising preclinical results in the area of oncology and is currently being explored in human imaging studies. The first translational studies have demonstrated the safety and feasibility of the technique in patients with prostate, renal, breast and pancreatic cancer, as well as revealing a successful response to treatment in breast and prostate cancer patients at an earlier stage than multiparametric MRI. This review will focus on the strengths of the technique and its applications in the area of oncological body MRI including noninvasive characterisation of disease aggressiveness, mapping of tumour heterogeneity, and early response assessment. A comparison of hyperpolarised 13C-MRI with state-of-the-art multiparametric MRI is likely to reveal the unique additional information and applications offered by the technique.

In the present review, the authors report the published evidence on the use of functional imaging with FDG-PET/CT in assessing the final response to treatment in Hodgkin lymphoma. Despite a very high overall Negative Predictive Value of post-chemotherapy PET on treatment outcome ranging from 94% to 86%, according to different treatment intensity, the Positive Predicting Value proved much lower (40–25%). In the present review the Authors discuss the role of PET to guide consolidation RT over a RM after different chemotherapy regimens, both in early and in advanced-stage disease. A particular emphasis is dedicated to the peculiar issue of the qualitative versus semi-quantitative methods for End-of Therapy PET scan interpretation. A short hint will be given on the role of FDG-PET to assess the treatment outcome after immune checkpoint inhibitors.

Transcript Type

Objective It is debatable whether BCR-ABL1 transcript type has an impact on outcome of treatment of patients with CML, and it is not widely studied whether body weight influences response to treatment. In this study, we tried to find out if any of these factors has an impact on response to treatment and outcome. Methodology We conducted a retrospective analysis of the files of 79 patients being treated in our center for CML with known BCR-ABL1 breakpoints, and patients’ management and response assessment was done based on ELN 2013 guidelines. The analysis was performed based on two main groups, obese vs. normal BMI, and then based on BCR-ABL1 transcripts: e13a2 vs. e14a2. Cumulative incidence of MMR, CCyR, and DMR were estimated using the Kaplan–Meier survival curve method, and comparisons between groups were performed by the Log-rank/Gray test methods. Results/conclusion In the patient-cohort studied, there was no statistically significant difference in molecular response between patients with CML based on body weight or transcript type although patients in the obesity group achieved higher and faster MMR with no statistical significance.

Background: Metabolic tumor volume (MTV) measured by FDG-PET/CT is becoming established as an independent risk factor for treatment failure in Hodgkin lymphoma (HL). Moreover, response to treatment with novel agents including checkpoint inhibitors may be better reflected by a decrease in MTV than by currently used response criteria. Our aim was to evaluate the early response to first-line HL treatment with the PD-1 inhibitor nivolumab using MTV. Methods: The analysis set included 59 patients with newly diagnosed, early-stage unfavorable HL treated within the prospective, multicenter, open label, randomized, phase II NIVAHL trial of the German Hodgkin Study Group (GHSG). Patients in NIVAHL were randomized to receive either four double cycles of nivolumab, doxorubicin, vinblastine, and dacarbazine (4x Nivo-AVD, group A, n=31) or a sequential therapy starting with 4x nivolumab monotherapy followed by 2xNivo-AVD and 2x AVD (group B, n=28). Early response to treatment was assessed at a 1st interim restaging after either 2x Nivo-AVD or 4x nivolumab. All NIVAHL patients who underwent PET at both initial staging and early response assessment, with images available to the central review panel for quantitative analysis before April 30th 2019, were included. MTV was calculated using a fixed SUV threshold of 4 for both staging and restaging. Results: Patient characteristics of the MTV analysis subset presented here did not differ in any relevant way from the overall NIVAHL trial population. Median age of the 59 patients was 27 years (range 18-57) with a female predominance (61%). All patients presented with stage II disease (IIB 27%) and ≥3 involved areas was the most common risk factor (75%) followed by elevated erythrocyte sedimentation rate (51%), extranodal disease (17%) and large mediastinal mass (14%). Mean MTV at initial staging was 124 ml (range 4 - 578 ml) and 177 ml (11 - 581 ml) in groups A and B, respectively. In both groups a marked decrease in MTV was observed at the 1st interim restaging (Figure 1): After 2x Nivo-AVD all patients in group A showed a reduction of MTV >80% (mean percentage change in MTV -99.8%). In group B a reduction of MTV >80% was observed in 26/28 patients (93%), while in 2/28 patients an increase <10% was observed (mean percentage change in MTV -91%; Figure 1). The mean residual MTV at interim restaging after 2x Nivo-AVD was 0.4 ml (range 0 - 8) in group A and 11 ml after 4x nivolumab in group B (range 0 - 176). The reduction of MTV was observed irrespective of initial MTV with a similar mean percentage change in patients above and below the median MTV in both groups. When applying the Deauville score, however, the number of patients presenting with a Deauville score ≥4 was higher in the group with an initial MTV above the median MTV than in the group where initial MTV lay below the median value. Using the Lugano criteria and a Deauville score of 4 or higher as cut-off for PET-positivity, early interim complete remission was observed in 81% of patients after 2xNivo-AVD, as compared to 51% after 4x nivolumab monotherapy. Further analyses regarding MTV and response at the 2nd and end-of-treatment restaging as well as survival data are not yet available due to limited follow-up. These data will be available at the time of presentation and shown at the meeting. Conclusions: Marked reductions of MTV demonstrate an excellent early efficacy for both 2x Nivo-AVD and 4x nivolumab as 1st-line therapy for early-stage unfavorable HL. The unexpectedly and previously unreported high MTV reduction with nivolumab monotherapy indicates a relevant potential of anti-PD1 mono- or debulking-therapy in the 1st-line treatment of early-stage unfavorable HL. Early interim response assessment based on MTV may help to identify HL patients treated with anti-PD1 antibodies in whom a significant reduction or even omission of chemotherapy could be considered. MTV appears to have the potential to accurately measure response to immune checkpoint inhibition. However, correlation of early MTV reduction with response at the end of treatment or with survival data is pending. Disclosures Borchmann: Novartis: Honoraria, Research Funding.

Abstract INTRODUCTION Response assessment in the treatment of glioblastoma (GB) based on MR-imaging is still challenging, in particular for immunotherapeutic strategies. Several assessment tools have been proposed. In this post-hoc analysis we compared response assessment criteria (MacDonald, RANO, mRANO, Vol.-mRANO, iRANO) in newly diagnosed GB patients treated with tumor lysate-charged autologous dendritic cells (Audencel) and determined the differences in prediction of progression free survival (PFS) and overall survival (OS). METHODS 76 patients with newly diagnosed GB enrolled in a multicenter randomized phase II trial receiving standard of care (SOC, n= 40) or SOC + Audencel vaccine (n= 36) were included. Tumor volumes were calculated by semiautomatic segmentation. To detect differences in PFS among the assessment criteria Kruskal-Wallis-test, for correlation analysis Spearman test was used. RESULTS There was a significant difference in median PFS based on the different assessments (mRANO 8.55 months [9.10-14.03], Vol.-mRANO 8.61 months [9.72-14.92] compared to MacDonald 4.04 months [5.21-8.75] and RANO 4.16 months [5.28-8.61]. For the vaccination arm only, median PFS by iRANO was 5.95 months [5.70-11.54]). There was no difference in PFS between SOC and SOC + Audencel using the different response criteria. The best correlation between PFS and OS was detected for mRANO (r= 0.65, p&lt; 0.001) and Vol.-mRANO (r= 0.69, p&lt; 0.001). At an 8-month landmark, the impact of progressive disease on median OS was best shown for mRANO (13.70 months [13.13-18.98], and Vol.-mRANO 12.03 months [12.51-17.94]) compared to MacDonald 17.97 months [15.45-20.92], RANO 17.97 months [15.92-20.95] and iRANO 17.34 months [14.99-22.73]. CONCLUSION When comparing different response assessments in GB patients treated with dendritic cell-based immunotherapy the best correlation between PFS and OS was observed for mRANO and Vol.-mRANO. Overall, no difference in PFS and OS was seen between the two treatment arms. iRANO was not superior for predicting OS in patients treated with Audencel.
