e19026 Background: PET scan is frequently utilized in FL. Reduced EFS has been observed in DLBCL pts with SL treated with RCHOP (Held, JCO 31:4115, 2013). Methods: We performed a retrospective single center study to assess outcomes of FL pts with PET avid SL between January 2005 and November 2015. 131 pts with newly diagnosed FL and PET performed within 1 month of diagnosis were included. Results: 32 of these pts had SL (median 4, range 1-11) on initial PET. Median age was 57 (range 43-79), 15 (47%) were female, 30 (94%) had stage IV disease, LDH was elevated in 6 (19%), 6 (19%) had bulky disease > 6 cm, and FLIPI-1 score was low in 5, intermediate in 11, and high 16 pts. 27 pts had grade (gr) 1-2 FL, 2 had gr 3a, and 3 had gr 3 (not classified). All but 1 patient received rituximab (R)-containing therapy (9 received BR, 7 received RCHOP, 5 RCVP, 9 other). 8 pts received maintenance R, and none received radiation. There were no statistically significant differences in median age, tumor gr, LDH, or use of anthracycline containing therapy (28% in SL group vs 16% in non-SL group, p = 0.13) in pts with SL compared to those without SL (n = 99). Pts with SL had higher incidence of bone marrow involvement (27% vs 9%, p = 0.013). With a median follow-up of 35 months, SL pts had 44% rate of transformation to DLBCL compared 12% in non-SL pts (p = 0.004). Median PFS was 45.8 months in SL pts not-reached in non-SL pts (p = 0.003). Median OS was 105.9 months in SL pts and not reached in non-SL pts (p = 0.08). In the multi-variate analysis, SL (p = 0.037), male gender (p = 0.048), higher FLIPI-1 score (p = 0.009), and absence of anthracycline containing therapy (p = 0.005) were significantly associated with decreased PFS using backward selection. Conclusions: The presence of PET identified SL in previously untreated FL is associated with an increased risk of transformation and reduced PFS in this single center retrospective analysis. Larger studies of uniformly treated pts are needed to validate these data. The identification of high-risk PET avid SL in FL pts in future prospective therapeutic trials could be used to select pts for specific induction regimens, maintenance rituximab, or consolidative radiation.

Abstract In follicular lymphoma (FL), detection of bone marrow (BM) involvement (BMI) by 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) improves the accuracy of staging vs BM biopsy (BMB) alone. Our objective was to determine the diagnostic utility of PET for BMI FL and the prognostic value of BMI by PET (positive PET result [PET+]). Records of patients (2002-2016) with PET and BMB at the time of initial treatment were reviewed. BMI was identified by positive BMB result (BMB+) and/or unifocal or multifocal BM FDG uptake on blindly reviewed PET scans with no corresponding CT abnormality (PET+). Among 261 patients, BMI was diagnosed in 78 patients (29.9%) by PET+, in 81 patients (31.0%) by BMB+, and in 113 patients (43.3%) by either PET+ or BMB+. PET+ upstaged 24 patients to stage IV, including 10 from stages I or II to stage IV. Median duration of follow-up was 6.0 years (range, 0-16.6 years). In univariate analysis, a high Follicular Lymphoma International Prognosis Index (FLIPI) score, PET+, and BMB+ correlated with shorter progression-free survival (PFS; all P ≤ .03), and high FLIPI, PET+, and combined PET+ and BMB+ with shorter overall survival (OS; all P ≤ .01). In multivariate analysis, PET+ was the only independent predictor of PFS, whereas high FLIPI score and PET+ predicted OS (P ≤ .03). Combined PET and BMB identify BMI more accurately than either BMB or PET alone, but BMB rarely adds critical information. For patients initiating treatment of FL, identification of BMI by PET is predictive of PFS and OS.

Abstract Abstract 2710 Introduction Recent refinement in B-cell lymphoma classification by the WHO in 2008 has defined an entity that exists in the gray zone between diffuse large B-cell lymphoma (DLBCL) and Burkitt lymphoma (BL). Varying in morphology, immunohistochemical, or genetic features, B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and BL (Intermediate DLBCL/BL) has been reported to have a poor clinical outcome. We aim to describe the clinical factors affecting outcomes and compare therapy response in a representative population. Methods A retrospective search of the Nebraska Lymphoma Study Group Registry from 1983–2009 meeting the diagnostic criteria for Intermediate DLBCL/BL yielded clinical data at presentation, follow-up, and treatment information. Treatments were grouped as CHOP-like +/− Rituximab (R) vs. intensive regimens (e.g. CODOX-M +/− R, R-EPOCH). Diagnostic slides were re-reviewed to verify the diagnosis. Probabilities of progression-free survival (PFS) and overall survival (OS) were approximated using Kaplan-Meier method. Cox proportional regression analysis was used to evaluate the clinical variables associated with risk of treatment-failure and death. Results Our cohort of 63 patients had a median age of 69 (19–93), male sex in 49%, a Karnofsky performance status of at least 80 at time of diagnosis in 73%, an elevated serum lactate dehydrogenase (LDH) in 62%, and stage IV disease in 46%. International Prognostic Index (IPI) scores were low in 38%, low-intermediate in 27%, high-intermediate in 24% and high in 11%. The probability of PFS at 5 and 10 years was 25% (95% CI 15–37%) and 10% (95% CI 4–21%) respectively, with a median time to treatment-failure of only 5.7 months. The 5 and 10 year probability of OS was 32% (95% CI 21–44%) and 20% (95% CI 10–32%) respectively, with a median survival of 10.4 months. Univariate regression analysis showed the following factors to be associated with an increased risk for treatment-failure: Ann Arbor stage IV disease (HR 2.49, 95% CI 1.33–4.68); elevated LDH (HR 1.85, 95% CI 1.02–3.37) and having at least 2 extra-nodal sites (HR 2.12, 95% CI 1.12–4.04). The following factors were associated with an increased risk of death: elevated LDH (HR 2.03, 95% CI 1.08–3.81), stage IV disease (HR 1.88, 95% CI 1.00–3.45), and having at least 2 extra-nodal sites (HR 2.26, 95% CI 1.15–4.40). The IPI scores of low-intermediate, high-intermediate, and high risk were associated with treatment-failure (HR 2.01, 95% CI 1.00–4.11; 4.62, 95% CI 2.11–10.14; 6.11, 95% CI 2.31–16.17) respectively, and death (HR 2.57, 95% CI 1.23–5.37; 3.13, 95% CI 1.41–6.94; 8.30, 95% CI 3.07–22.43) respectively. The median OS of patients who received CHOP/CHOP-like regimens +/− R was 8.7 months, whereas those who received a more intensive regimen +/− R was 45 months (p=0.38). The median PFS was 5.4 months for CHOP/CHOP-like regimens +/− R and 52.3 months for a more intensive regimen (p=0.08) (Fig.1).Figure 1.Progression free survival intensive versus CHOP/CHOP-like regimens +/− Rituximab, p=0.08Figure 1. Progression free survival intensive versus CHOP/CHOP-like regimens +/− Rituximab, p=0.08 Summary Our analysis confirmed poor clinical outcome with stage IV disease, elevated serum LDH, at least 2 extra-nodal sites at presentation, or worse IPI score. There was a better outcome with intensive chemotherapy regimens. This study underscores the importance of early identification and proper treatment choice.

11057 Background: BRM, a key catalytic subunit of the SWI/SNF chromatin remodeling complex, is a putative tumor susceptibility gene in NSCLC. Loss of BRM expression occurs in 15% of NSCLC, and has been linked to adverse outcome. Recently, our group has shown that variants of two novel BRM promoter insertion polymorphisms (BRM-741, BRM-1321) lead to loss of BRM expression by recruiting histone deacetylases; individuals carrying homozygous variants for both polymorphisms have doubled NSCLC risk; pharmacological reversal of these epigenetic changes is a potentially viable therapeutic strategy. We thus evaluated the effect of BRM promoter variants on survival outcomes of advanced NSCLC patients, where initial clinical trials are likely to be focused. Methods: 564 stage III-IV NSCLC patients were genotyped for the BRM promoter variants using Taqman. Association of BRM variants and overall (OS) and progression-free survival (PFS) were assessed using Cox proportional hazard models adjusted for prognostic variables. Results: Among our patients, 73% were Caucasian, 52% male, median age 63yrs, 55% stage IV disease, and 67% adenocarcinoma. Median OS was 1.6yrs; median follow up, 3.6yrs. The frequency of homozygosity was BRM-741, 23%; BRM-1321, 21%; both, 12%. Homozygous variants of BRM-741 were strongly associated with worse OS (adjusted HR [aHR] 2.3 [p=2x10E-8]) and PFS (aHR 2.0 [p=2x10E-7]) compared to the wild types. Similar findings were observed for BRM-1321 homozygous variants (aHR for OS 1.8 [p=8x10E-5] and aHR for PFS 1.6 [p=2x10E-4]). Carrying homozygous variants of both BRM-741 and BRM-1321 was associated with substantially worse OS (aHR 2.3 [p=1x10E-5]) and PFS (aHR 2.2 [p=3x10E-6]), with similar associations seen among the stage III (aHR for OS 2.3 [p=6x10E-6]) and stage IV (aHR for OS 2.5 [p=5x10E-6]) patients. Conclusions: The same two homozygous BRM promoter variants that are associated with increased risk of NSCLC are also strongly associated with adverse OS and PFS in this cohort of stage III-IV NSCLC patients. Validation of results in a clinical trial dataset is underway, and will better elucidate the prognostic significance of these BRM promoter variants.

This retrospective study examined the role of 18F-fluorodeoxyglucose-positron emission tomography/computed tomography (18F-FDG-PET/CT) in stage-related therapy of follicular lymphomas (FL). Twelve patients each in stages I and II, 13 in stage III and 11 in stage IV were treated in the Department of Radiation Oncology, University Hospital of Muenster, Germany from 2004 to 2016. Radiotherapy (RT), as well as additional chemoimmunotherapy were analyzed with a median follow-up of 87.6 months. Ultrasound (US), CT and 18F-FDG-PET/CT were used to determine progression-free survival (PFS), overall survival (OS) and lymphoma-specific survival (LSS) over 5- and 10- years. 23 of 24 patients with stage I/II (95.8%) had complete remissions (CR) and 17 of 24 patients with stages III/IV FL showed CR (70.8%). 5- and 10-year PFS in stages I/II was 90.0%/78.1% vs. 44.3%/28.5% in stages III/IV. 5- and 10-year OS rates in stages I/II was 100%/93.3% vs. 53.7%/48.4% in stages III/IV. 5- and 10-year LSS of stages I/II was 100%/93.8% vs. 69.2%/62.3% in stages III/IV. FL of stages I/II, staged by 18F-FDG-PET/CT, revealed better survival rates and lower risk of recurrence compared to studies without PET/CT-staging. Especially, patients with PET/CT proven stage I disease showed significantly better survival and lower relapses rates after RT.

AbstractA retrospective, single-center analysis of 14 cases of Candida endocarditis (from 355 candidemia cases during the years 2012–2019) revealed a high in-hospital mortality (57.1%), a high proportion of healthcare-associated infections (13/14) and a high treatment preference for echinocandins. Transthoracic echocardiography and 18F-FDG PET/CT had a sensitivity of 54.5% and 57.1%, respectively. Patients were older than previously described and most patients with Candida endocarditis had persistent candidemia for ≥ 3 days despite antifungal therapy.

Abstract Purpose Fluorine-18 fluorodeoxyglucose positron emission tomography combined with computed tomography (FDG PET/CT) is the standard for staging aggressive non-Hodgkin lymphoma (NHL). Limited data from prospective studies is available to determine whether initial staging by FDG PET/CT provides treatment-relevant information of bone marrow (BM) involvement (BMI) and thus could spare BM biopsy (BMB). Methods Patients from PETAL (NCT00554164) and OPTIMAL>60 (NCT01478542) with aggressive B-cell NHL initially staged by FDG PET/CT and BMB were included in this pooled analysis. The reference standard to confirm BMI included a positive BMB and/or FDG PET/CT confirmed by targeted biopsy, complementary imaging (CT or magnetic resonance imaging), or concurrent disappearance of focal FDG-avid BM lesions with other lymphoma manifestations during immunochemotherapy. Results Among 930 patients, BMI was detected by BMB in 85 (prevalence 9%) and by FDG PET/CT in 185 (20%) cases, for a total of 221 cases (24%). All 185 PET-positive cases were true positive, and 709 of 745 PET-negative cases were true negative. For BMB and FDG PET/CT, sensitivity was 38% (95% confidence interval [CI]: 32–45%) and 84% (CI: 78–88%), specificity 100% (CI: 99–100%) and 100% (CI: 99–100%), positive predictive value 100% (CI: 96–100%) and 100% (CI: 98–100%), and negative predictive value 84% (CI: 81–86%) and 95% (CI: 93–97%), respectively. In all of the 36 PET-negative cases with confirmed BMI patients had other adverse factors according to IPI that precluded a change of standard treatment. Thus, the BMB would not have influenced the patient management. Conclusion In patients with aggressive B-cell NHL, routine BMB provides no critical staging information compared to FDG PET/CT and could therefore be omitted. Trial registration NCT00554164 and NCT01478542

Aim: To perform a comprehensive analysis of discordances between contrast-enhanced CT (ceCT) and 18F-FDG PET/CT in the evaluation of the extra-cerebral treatment monitoring in patients with stage IV melanoma. Materials and methods: We conducted a retrospective monocentric observational study over a 3-year period in patients referred for 18F-FDG PET/CT and ceCT in the framework of therapy monitoring of immune checkpoint (ICIs) as of January 2017. Imaging reports were analyzed by two physicians in consensus. The anatomical site responsible for discordances, as well as induced changes in treatment were noted. Results: Eighty patients were included and 195 pairs of scans analyzed. Overall, discordances occurred in 65 cases (33%). Eighty percent of the discordances (52/65) were due to 18F-FDG PET/CT scans upstaging the patient. Amongst these discordances, 17/52 (33%) led to change in patient’s management, the most frequent being radiotherapy of a progressing site. ceCT represented 13/65 (20%) of discordances and induced changes in patients’ management in 2/13 cases (15%). The most frequent anatomical site involved was subcutaneous for 18F-FDG PET/CT findings and lung or liver for ceCT. Conclusions: Treatment monitoring with 18F-FDG PET/CT is more efficient than ceCT and has a greater impact in patient’s management.

Abstract This retrospective study was undertaken to investigate the association of relative dose intensity (RDI) with the outcome of Hodgkin lymphoma (HL) patients with advanced stage disease receiving ABVD (doxorubicin, bleomycin, vinblastine, dacarbazine) and escalated BEACOPP regimen (bleomycin, etoposide, doxorubicin, cyclophosphamide, vincristine, procarbazine, prednisone). A total of 114 HL patients treated between 2004 and 2013 were enrolled for evaluation. RDI calculations were based on a Hryniuk's model. The association of variables with overall survival (OS) and progression-free survival (PFS) was analysed using univariate and multivariate Cox proportional hazards models. The median age of patients was 39 years, majority of patients were males and had stage IV disease. Fifty-four patients received ABVD and 60 received BEACOPP chemotherapy with 24 and 4 deaths, respectively. Patients in BEACOPP group were significantly younger with lower Charlson comorbidity index (CCI) in comparison with ABVD group, making the comparison of groups impossible. In ABVD group, RDI was not significantly associated with OS (p=0.590) or PFS (p=0.354) in a multivariate model where age was controlled. The low number of events prevented the analysis in the BEACOPP group. Patients' age was strongly associated with both OS and PFS: all statistically significant predictors for OS and PFS from univariate analyses (chemotherapy regimen, CCI, RDI) lost its effect in multivariate analyses where age was controlled. Based on our observations, we can conclude that RDI is not associated with the OS or PFS after the age is controlled, neither in all patients combined nor in individual chemotherapy groups.
