Purpose: To identify survival predictors and to design a prognostic score useful for distinguishing risk groups in immunocompetent patients with primary CNS lymphomas (PCNSL). Patients and Methods: The prognostic role of patient-, lymphoma-, and treatment-related variables was analyzed in a multicenter series of 378 PCNSL patients treated at 23 cancer centers from five different countries. Results: Age more than 60 years, performance status (PS) more than 1, elevated lactate dehydrogenase (LDH) serum level, high CSF protein concentration, and involvement of deep regions of the brain (periventricular regions, basal ganglia, brainstem, and/or cerebellum) were significantly and independently associated with a worse survival. These five variables were used to design a prognostic score. Each variable was assigned a value of either 0, if favorable, or 1, if unfavorable. The values were then added together to arrive at a final score, which was tested in 105 assessable patients for which complete data of all five variables were available. The 2-year overall survival (OS) ± SD was 80% ± 8%, 48% ± 7%, and 15% ± 7% (P = .00001) for patients with zero to one, two to three, and four to five unfavorable features, respectively. The prognostic role of this score was confirmed by limiting analysis to assessable patients treated with high-dose methotrexate-based chemotherapy (2-year OS ± SD: 85% ± 8%, 57% ± 8%, and 24% ± 11%; P = .0004). Conclusion: Age, PS, LDH serum level, CSF protein concentration, and involvement of deep structures of the brain were independent predictors of survival. A prognostic score including these five parameters seems advisable in distinguishing different risk groups in PCNSL patients. The proposed score and its relevance in therapeutic decision deserve to be validated in further studies.

7543 Background: Central nervous system (CNS) relapse occurs in 2-6% of DLBCL patients (pts) increasing to 10% or more in high-risk groups. Intrathecal (IT) or intravenous high-dose methotrexate (HD MTX) have limited if any prophylactic impact on CNS relapse. To address the role of systemic first-line therapy in pts tolerating intensified strategies (R-ACVBP, R-(Mega)CHOEP, R-CHO(E)P), we compared CNS relapses occurring in a large cohort of pts ≤60 years. Methods: We conducted a retrospective analysis including previously untreated pts with DLBCL by central review, age 18-60 years, from multicenter clinical trials conducted by LYSA and GLA/DSHNHL (Table). We assessed the risk of CNS relapse in matched cohorts based on the aaIPI. Results: A total of 2203 pts were included. Median age was 47 years (18-60). 455 pts were treated with R-ACVBP, 444 with R-(Mega)CHOEP, 1304 with R-CHOP. Distribution of CNS IPI was not significantly different comparing R-ACVBP to R-CHO(E)P groups within aaIPI categories (Table). PFS and OS were comparable according to treatment within aaIPI groups, also adjusted for prognostic factors. No CNS events occured during observation time of 3 years in pts with aaIPI 0. In pts with aaIPI 1, no CNS event occured in the R-ACVPB arm, the 3y-cumulative incidence of CNS relapse for pts treated with R-CHO(E)P group was 1.0% (95%CI 0.3-1.7). In pts with aaIPI 2,3 and intermediate/high CNS IPI, four (1.6%) treated with R-ACVBP experienced relapse in the CNS compared to 15 (3.9%) pts treated with R-(Mega)CHO(E)P (3y-cumulative incidence 1.6% (95%CI 0-3.2) vs. 4.0% (95%CI 2.0-6.0). Conclusions: CNS relapse was extremely rare in younger DLBCL pts with aaIPI 0 or 1; prophylactic measures are not warranted. In pts with aaIPI 2,3 (and intermediate/high CNS-IPI), only 4 (1.6%) CNS relapses were seen with the R-ACVBP while 15 (3.9%) relapses did occur after R-(Mega)CHO(E)P. This analysis underlines the important role of the systemic therapy in controling CNS relapse.[Table: see text]

e17026 Background: Ra-223 is a treatment option for mCRPC pts with bone metastases according to the survival benefit observed compared to placebo in the ALSYMPCA trial. In the last years, many studies showed this benefit in the real-life pts is lower than that reported in the trial, probably due to a suboptimal selection of pts with poor prognostic characteristics. Therefore, the identification of prognostic factors to select mCRPC pts most likely to benefit from Ra-223 is needed. The multicentre retrospective BIO-Ra-223 study has investigated the prognostic role of peripheral blood immune cells and clinical factors to develop a novel prognostic score for mCRPC pts treated with Ra-223. Methods: Complete blood count was assessed before Ra-223 treatment calculating neutrophil-to-lymphocyte ratio (NLR), derived NLR (dNLR), lymphocyte-to-monocyte ratio (LMR), platelet-to-lymphocyte ratio (PLR), systemic inflammation index (SII). Clinical factors included pre-treatment Eastern Cooperative Oncology Group performance status (ECOG PS), Gleason Score (GS) group, number of bone metastases, alkaline phosphatase (ALP), line of therapy, previous chemotherapy and the presence of lymphadenopathies. Statistical analyses included survival ROC curves for biomarkers’ cutoffs, univariable and multivariable Cox analyses, internal validation, c-index calculation and Schneeweiss scoring system. Results: From September 2013 to July 2020, 519 mCRPC pts received Ra-223 as 1st-2nd, 3rd-4th and further-line in 48%, 38% and 14% of pts. The median overall survival (mOS) of the entire cohort was 19.9 months. All biomarkers and clinical factors (except for GS group) significantly predicted OS at the univariable analyses. In the multivariable ones, all biomarkers, ECOG PS, number of bone metastases and ALP significantly correlated with OS. The multivariable model with NLR (< 3.1 vs ≥3.1), ECOG PS (0-1 vs 2-3), number of bone metastases (< 6, 6-20, > 20) and ALP (< 220 vs ≥220) showed the highest c-index (0.711), which was maintained after internal validation (bootstrap re-sampling) (c-index: 0.707). Using the Schneeweiss scoring system, ten categories were identified in 494 pts with complete data and merged in two prognostic groups with distinctive OSs: group 1 (score 0-4, 337 pts) with a mOS of 27.8 months and group 2 (score 5-10, 157 pts) with a mOS of 9.7 months (HR 4.03, p < 0.001). Conclusions: The obtained score, composed of NLR, ECOG PS, number of bone metastases, and ALP identifies two distinctive prognostic groups of mCRPC pts. Moreover, this score is easily and widely applicable for clinical practice and trials at no additional costs. Although external validation is needed, these preliminary results showed that this novel prognostic score is promising and could help the patients’ selection for Ra-223 treatment.

Abstract Background Our previous study indicated a therapeutic effect of Shi-Zhen-An-Shen-Tang (SZAST), a Chinese herb formula, on schizophrenia, but the related mechanism is unknown(citation). A large body of evidence suggests the important role of white matter of the brain in the pathophysiology of schizophrenia. This study was designed to evaluate the effect of SZAST on schizophrenia with demyelinated mice. Methods Male C57BL/6 mice were given mixed cuprizone (CPZ, a copper chelator, 0.2 %, w/w) rodent chow for six successive weeks to induce demyelination. During the last two weeks, mice were given an oral gavage of saline, or SZAST of three different doses (a low dose of 5.5g·kg-1·d-1, a medium dose of 8.24g·kg-1·d-1, or a high dose of 10.98 g·kg-1·d-1), or quetiapine, respectively. Behavioral tests were conducted after the last treatment. Meanwhile, the expression of myelin basic protein (MBP) and neuregulin-1(NRG1) in the brain was tested by immunohistochemistry staining or Western Blot. Results Mice exposed to CPZ for six weeks showed obvious schizophrenia-like behaviors, including lower nest-building activity, sensory gating activity, and higher locomotor activity. CPZ-fed mice also displayed a lower myelin density in the corpus callosum, hippocampus, and cerebral cortex and a reduction of MBP and NRG1 protein in the hippocampus compared with controls. Both quetiapine and SZAST significantly alleviated the abnormal schizophrenia-like behaviors and the impairment of myelin sheath in CPZ-fed mice, however, SZAST with medium dose showed better neuroprotective effect than the low dose or the high dose of SZAST. Furthermore, the expression of NRG1protein in the hippocampus was slightly, but not significantly increased in all SZAST-treated and quetiapine-treated groups. Discussion These results indicate that the neuroprotective effect of SZAST in demyelinated mice might partially relate to remyelination in the hippocampus in CPZ-fed mice.

A 23-year-old lady presented with vertigo and imbalance in walking, blurring of vision, diplopia, and headache, in addition to numbness in the lower limbs over a period of six days. On examination patient had nystagmus, ataxia, positive Romberg test, and hyperreflexia. MRI examination of the brain and spinal cord showed evidence of faint bright signal intensity foci in T2/FLAIR involving bilateral cerebral hemispheres, subcortical deep white matter, bilateral thalami, posterior pons and left brachium pontis, and basal ganglia, with small nodular enhancement that aligned along curvilinear structures; those lesions also were apparent along the spinal cord at multiple levels. The clinical and radiological features suggested CLIPPERS (chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids) syndrome. Symptoms improved dramatically with high dose oral corticosteroids. Our report addresses the radiological and clinical pattern of a case of CLIPPERS rhombencephalitis, with added superior and inferior extension to involve the brain and spinal cord, which is to emphasize the importance of raising the awareness of this disease and the combined role of radiologist and physicians for the diagnosis of this potentially treatable entity, responsive to glucocorticosteroid immunosuppression.

The benefits from medical treatment in colorectal cancer are limited. Fluorouracil remains the only recognized drug, and how to treat unresponsive patients is still debated. To evaluate the role of folinic acid (FA) in circumvence resistance in colorectal cancer, 28 patients pretreated with fluoropyrimidine were candidated to receive one of the following schedules: fluorouracil (600 mg/m2) associated with FA (500 mg/m2) weekly for 6 weeks (Regimen A: 21 cases), or fluorouracil (370 mg/m2) plus FA (200 mg/m2) dally for 5 days every 4 weeks (Regimen B: 7 cases). Fourteen patients were pretreated with doxifluridlne, a new fluoropyrimldine derivative with a peculiar mechanism of action, and the remaining 14 patients with fluorouracil. All but 2 patients were unresponsive to first-line treatments. When the treatment began, the median age of the patients was 60 years (range, 30-68). The performance status (ECOG) was 0/1 in 25 of them, and the primary tumor was in the colon and rectum in 19 and 9 patients, respectively. Sites of disease were liver (64 %), lung (35 %), local recurrence (10 %) and peritoneum (10 %). A median of 3 cycles (range, 1-7) was delivered, and no objective response was observed in the group of patients pretreated with doxlfluridine or in the group pretreated with fluorouracil. In 5 cases a significant decrease in baseline CEA values was observed. Therapy was well tolerated, and no grade 4 toxicity was encountered. Severe toxicity was limited and included diarrhea (7 patients), stomatitis (1 patient) and nausea/vomiting (1 patient). High-dose FA has no role in reversing resistance to fluoropyrimidine, and other mechanisms of refractoriness are surely involved. FA should be associated with fluoropyrimidine as first-line therapy together with other biochemical modulators. Further rescue therapies need to be developed.

Abstract Abstract 3089 Introduction: High-dose chemotherapy (HDT) and autologous stem-cell transplantation (ASCT) demonstrated high efficacy in the treatment of newly-diagnosed primary CNS lymphoma (PCNSL) in eligible patients (pts). Prognosis of PCNSL is associated with several clinical and histopathological risk factors (RF). Early complete response (CR) during chemotherapy (CHT) was recently reported to be an additional independent prognostic factor in pts undergoing polychemotherapy without HDT+ASCT. In this analysis, we examined the extent to which known RF determined survival in pts who were treated with HDT-ASCT. We additionally investigated the impact of HDT-ASCT specific factors (e.g. conditioning regimen) on survival. Pts. and Methods: Retrospective multicenter (N=10) analysis of 100 pts with untreated PCNSL who underwent HCT-ASCT with or without whole brain radiotherapy (WBRT). We used univariate and multivariate Cox regression analysis to investigate the prognostic impact of the following factors on overall survival (OS): early CR, age, performance status, involvement of deep brain structures, and LDH serum level and thiotepa dose. Until now data of 82 pts have been analyzed. Results: Median age at diagnosis was 53 years (range 23–69), the majority was male (67%). After a median follow-up of 58 months median OS was reached after 121 mo (range 3–149 mo). Before HDT+ASCT, 48/82 pts (58%) did not achieve CR (35 PR, 3 SD, 10 PD). After HDT+ASCT, 54/82 pts (66%) were in CR and altogether 39% of the pts were irradiated after HDT+ASCT. Of note, of those pts with PD before HDT+ASCT, 5/10 achieved CR after HDT+ASCT without WBRT. Overall, at the time of last follow-up, 24 pts have died. Of the surviving pts, 50 were in CR (86%), 2 in PR (3%), 2 in SD, and 2 developed progression /relapse. None of the established RF (age, performance status, involvement of deep brain structures, and LDH serum level) significantly distinguished outcome with regard to OS in uni and multivariate analysis. Additionally, neither CR before HDT-ASCT, nor sex nor the dose of thiotepa (10mg versu 20mg/m2) was associated with decreased OS. Conclusion: We conclude that HCT+ASCT is able to neutralize established RF in PCNSL. HDT+ASCT is a high-efficient treatment option independently of remission rate before entering HDT. New prognostic factors for pts eligible for HCT-ASCT have to be identified to guide therapy and care for PCNSL pts and to define stratification criteria for future trials. Most recent follow up will be presented. Disclosures: No relevant conflicts of interest to declare.

460 Background: CS is a clinically useful prediction measure that adjusts prognosis of patients on the basis of survival since treatment initiation or therapy duration. CS was recently reported in mRCC patients treated with VEGF targeted therapy in patients stratified by Heng’s criteria. CS has not been reported in mRCC in the context of treatment with HD IL-2. Methods: Patients with histologically confirmed clear cell mRCC treated with HD IL-2 at the University of Utah Huntsman Cancer Institute from 2000 to 2012 were evaluated. Performance status and prognostic risk groups were included. Two-year CS was defined as the probability of surviving an additional 2 years from initiation of HD IL-2 to 18 months after the start of HD IL-2 at 3-month intervals estimated by Kaplan-Meier methodology. Results: A total of 85 patients were included with a median age of 56 years (range 32-76 years) and 79% (n = 67) were male. The median overall survival from HD IL-2 administration was 817 days. Stratification by Heng’s criteria at therapyinitiation resulted in survival estimates for the favorable (n = 13; 15%), intermediate (n = 56; 66%) and poor (n = 16; 19%) prognostic groups of 1616 (p = 0.1993 vs intermediate), 817 (p = 0.0041 vs poor), and 365 (p < 0.0001 vs favorable) days, respectively. Two-year overall CS increased from 56.2% at therapy initiation to 89.5% at 18 months (Table). Two-year CS stratified by Heng’s favorable, intermediate, and poor prognostic risk groups is presented in the Table. Conclusions: CS is a relevant prediction measure in the context of mRCC treated with HD IL-2.A longer survival interval from HD IL-2 treatment was associated with an increased survival probability. CS in this cohort was especially relevant in adjusting prognosis for patients with Heng’s intermediate risk. [Table: see text]

<p>Although not recommended by mainstream oncologists, intravenous injections of pharmacological ascorbate are currently an alternative therapy option for cancer patients. Research has not yet determined whether high-dose ascorbate interacts favourably with radiation therapy to increase DNA damage, and therefore cell death in cancer. Some studies suggest that ascorbate can act as a prooxidant and increase the cytotoxic effect of irradiation in vitro. Glioblastoma multiforme (GBM) is a primary brain astrocytoma that is highly therapy resistant, so patients would be advantaged if ascorbate radiosensitised their cancer.  In this investigation, flow cytometry and single cell gel electrophoresis (comet tail assay) were used to measure three indicators of DNA damage in GBM cells in response to ascorbate and irradiation, and were contrasted with immunofluorescence-revealed DNA damage from an intracranial mouse model of GBM.   The pro-oxidant, radiosensitisation role of ascorbate was confirmed, as measured by H2AX, 8OHdG, and DSBs in vitro. With all three of these markers of DNA damage, combinations of irradiation and ascorbate had increased damage compared with individual treatments. However preliminary in vivo evidence indicates that increased DNA damage did not occur in an animal model of GBM, and in fact ascorbate may protect from DNA damage in an in vivo context.  These findings complement previous results from our lab, and serve to fill in gaps in knowledge specifically around the DNA damaging effects of ascorbate. The unique nature of the brain environment, as enclosed by the blood brain barrier, prevents translation of data from other non-brain cancer studies, as such, this investigation also contributes to the exploration of a much needed avenue of research. Considering the context of ascorbate treatment as a potentially harmful currently used adjuvant, it is imperative to confirm or disprove its efficacy in a clinically relevant environment.</p>

Renal insufficiency (RI) is commonly seen in patients with hepatocellular carcinoma (HCC). The prognostic role of albumin-bilirubin (ALBI) grade in this special setting is unclear. We aimed to investigate the role of ALBI grade associated with the impact of RI on HCC. A prospective cohort of 3690 HCC patients between 2002 and 2016 were retrospectively analyzed. The Kaplan–Meier method and multivariate Cox proportional hazards model were used to determine survival and independent prognostic predictors. Of all patients, RI was an independent predictor associated with decreased survival. In multivariate Cox analysis for patients with RI, α-fetoprotein level ≥20 ng/mL, tumor size >3 cm, vascular invasion, distant metastasis, presence of ascites, performance status 1–2, performance status 3–4, and ALBI grade 2 and grade 3 were independent predictors of decreased survival (all p < 0.05). In subgroup analysis of patients with RI undergoing curative and non-curative treatments, the ALBI grade remained a significant prognostic predictor associated with decreased survival (p < 0.001). In summary, HCC patients with RI have decreased survival compared to those without RI. The ALBI grade can discriminate the survival in patients with RI independent of treatment strategy and is a feasible prognostic tool in this special patient population.
