e20001 Background: Multiple Myeloma (MM) is a neoplasm of the post-germinal center, terminally differentiated B-cells. MM accounts for 1% of all types of cancer and 10% for all hematologic malignancies. Chronic hepatitis C virus (HCV) is an infection that affects over 71 million patients worldwide. Cytotoxic agents and immunosuppressive therapy as steroids are the main line of therapy in lymphoid malignancies, but these drugs may exacerbate chronic viral hepatitis and cause uncontrolled replication of hepatitis viruses. The impact of HCV infection on MM patients remains unclear. Objective: To assess the impact of HCV infection on the prognosis and management of MM patients. Methods: A 10-year retrospective study of MM patients was conducted at Cairo University Clinical Oncology Department from January 2009 to April 2019. Results: During this time, 150 patients were diagnosed with MM, 109 (72.7%) were HCV negative, 24 (16%) were HCV positive, and 17 (11.3%) with unknown HCV status. The median age was 51 and 54 years for HCV negative and positive groups respectively, with a statistically insignificant difference (p-value > 0.2). In the multivariate analysis, HCV infection was not an independent factor related to overall survival (OS), however age, creatinine and hemoglobin levels correlated significantly with OS (p < 0.009, 0.008, 0.031 respectively). The median OS for the HCV negative group was 31.11 months (95% CI: 22.62 - 39.61) compared to 37.66 months (95% CI: 7.19 - 68.13) for the HCV positive group. The median progression-free survival (PFS) for all patients was 18.9 months, for HCV positive patients was 15.36 months (95% CI: 13.18 – 17.54), and for HCV negative patients was 20.49 months (95% CI: 14.13 – 26.85). Age below 60 years and creatinine level less than 2 mg/dL were statistically significant for favorable disease-free survival (DFS) (p < 0.030, 0.034 respectively). Conclusions: Age, creatinine and hemoglobin levels are significant prognostic factors in MM but HCV status doesn’t affect the overall survival or progression-free survival. HCV infection should not contraindicate MM therapy.

Purpose Epidemiologic studies show an association between hepatitis C virus (HCV) and B-cell non-Hodgkin's lymphoma (NHL). Treatment and outcome of patients with diffuse large-cell lymphoma (DLCL) and HCV infection are still a matter of debate. Patients and Methods We studied the HCV-positive patients with B-cell DLCL included in the Groupe d'Etude des Lymphomes de l'Adulte (GELA) programs LNH 93 and LNH 98. They were compared with the other patients with DLCL included in these programs. HCV infection prevalence was 0.5% (26 of 5,586 patients). Results Histologic types of HCV-positive DLCL were more frequently transformed from low-grade lymphoma than DLCL in HCV-negative patients (32% v 6%, P = .02). This is also supported by more frequent spleen involvement in HCV-positive patients (46% v 17%, P < .001). HCV-positive patients had more frequently elevated lactate dehydrogenase levels than other patients (77% v 55%, P = .02). Outcome of HCV-positive patients was poorer for overall survival (P = .02) but not for event-free survival (P = .13). After matching on age and prognosis factors, at 2 years of follow-up, the overall survival was 56% (95% CI, 33% to 76%) among HCV-positive patients, versus 80% (70% to 89%), and the event-free survival was 53% (33% to 72%) versus 74% (64% to 84%). The short-term hepatic toxicity of chemotherapy was strongly increased among HCV-positive patients. After exclusion of the two subjects with chronic hepatitis B virus infection, the overall proportion of subjects undergoing hepatic toxicity was 65% (15 of 23 patients). Conclusion HCV-positive patients with DLCL differ from other patients both at presentation and during chemotherapy. Specific protocols evaluating antiviral therapy should be designed for these patients.

Abstract Backround: Arsenic trioxide (ATO), an active agent against multiple myeloma, has been shown to be synergistic with melphalan both in vitro and in vivo. We conducted a phase I/II trial to determine the safety and efficacy of a combination of arsenic trioxide, melphalan and ascorbic acid (AA) as prepaprative regimen in patients undergoing high-dose therapy (HDT) and autologous hematopoietic progenitor cell transplantation (AHPCT) for multiple myeloma (MM). We also assessed the impact ATO levels on melphalan pharmacokinetics (PK), engraftment and toxicity. Methods: Twenty-five patients with secretory myeloma (11 females, 14 males median age: 53, range: 49 – 69) were treated b/w 4/04 and 1/05. All patient received melphalan 100 mg/m2 IV on days -4 and -3 and AA 1000 mg/day IV on days −9 to −3. Patients were randomized to 3 arms; no ATO (arm 1), ATO 0.15 mg/kg IV on days −9 to −3 (arm 2) and ATO 0.25 mg/kg IV on days −9 to −3 (arm 3). Seven patients had a prior autograft. Median CD34 cells dose infused was 4.4 x 106/kg (range 2.3–10.9). Results: Patients were evenly matched except for a high median β2m level (3.6 vs. 2.4 in arms 1 and 2, p=0.04) in arm 3. With a median F/U of 7.1 months post autograft, no dose-limiting toxicity or non-relapse mortality was seen. Median ATO level on day 0 in arms 1, 2 and 3 were 0.2, 26.3 and 46.2 ng/ml, respectively. Toxicity was limited grade I or II nausea, vomitting and diarrhea. Median time to neutrophil engraftment (ANC &gt;500/dl) was 9 days. There were no engraftment failures or delays in the ATO arms. Response rates (RR) are shown in Table 1. With a median F/U of 7.1 months (range, 6.4 – 8.9 months), the progression-free survival (PFS) and overall survival (OS) are as shown in Figure 1. There was no significant difference in RR, PFS or OS between the 3 arms. Melphalan PK was not altered by ATO pretreatment. Conclusions: Arsenic trioxide, given in combination with melphalan and ascorbic acid as preparative regimen, is safe and well tolerated. A longer follow up is needed to determine the impact of this combination on survival.

Abstract The chromosomal abnormalities of del(13), t(4;14), and del(17p) are associated with poor progression-free survival (PFS) and shorter overall survival (OS) in newly diagnosed multiple myeloma (MM) treated with traditional chemotherapy. In patients with relapsed or refractory MM, a recent study demonstrated that lenalidomide (Revlimid®) can overcome poor prognosis conferred by del13q and t(4;14) but not del17p13 (Bahlis et al 2007). Here, we performed a retrospective analysis of medical records obtained from 49 clinical centers participating in the French Autorisation Temporaire d’Utilisation program. Patients with relapsed or refractory MM received dexamethasone 40 mg orally (days 1–4; 9–12 and 17–20 for 4 cycles, then days 1–4 beginning with cycle 5) and lenalidomide 25 mg orally on days 1–21 of a 28 day cycle. CD138-purified plasma cells were analyzed with fluorescent in-situ hybridization (FISH) for del(13), t(4;14), and del(17p) at diagnosis. Response and disease progression endpoints were evaluated using the European Group for Blood and Marrow Transplantation criteria. A multivariate analysis was performed to assess the impact of the following 7 variables on outcomes: any chromosomal change, prior bortezomib use, prior thalidomide use, prior transplant, progression on thalidomide, age, and number of lines of previous therapy. In total, 207 patients were included in the analysis; the median number of treatment cycles was 5 (range, 1–22). Most patients in the current study had received prior thalidomide (87%) or bortezomib (81%). The overall response rate (ORR) was 59%, including 7% complete response and 14% very good partial response. Median progression-free survival (PFS) and overall survival (OS) were 9.6 months and 15.1 months, respectively. These values are comparable to the recently published phase III trials (Weber et al., 2007; Dimopoulos et al., 2007), despite the higher median number of prior therapies in this analysis (5 vs. 3). Overall, 41% of patients had del(13), 14% had t(4;14) and 5% had del(17p). The ORR was significantly lower, and PFS and OS significantly shorter, in patients with del(13) compared with patients without del(13) (ORR: 43% vs. 71%, P<0.001; PFS: 5.0 months vs. 12.5 months, P<0.0001; OS: 10.4 months vs. 17.4 months, P=0.001). A similar pattern was observed in patients with t(4;14) versus patients without t(4:14) (ORR 39% vs. 62%, p=0.04; PFS 5.5 months vs. 10.6 months, p<0.01; OS 9.4 months vs. 15.4 months, p=0.005). Multivariate analysis identified hemoglobin (<10 g/dL), progression on thalidomide, and del(13) as independent predictors of reduced PFS (Table). There was a trend towards reduced PFS with prior bortezomib use and number of prior therapies. Age, sex, prior transplant, prior thalidomide use, and t(4;14) did not affect PFS. The results from the analysis indicate that del(13), progression on thalidomide, and hemoglobin levels ≥10 g/dL have a significant impact on outcomes in heavily pre-treated patients with relapsed or refractory MM. Randomized trials are needed to further assess these findings.

Abstract Introduction Immunoparesis, defined as suppression of uninvolved immunoglobulins (Igs), has been described as one of the most common indicators of immune dysfunction in patients with multiple myeloma (MM). The role of immunoglobulin recovery, however, has not been properly evaluated, in particular in the setting of immunomodulatory therapy. In the present study, we aimed to assess the impact of immunoparesis and Igs recovery after ASCT on Overall and Progression-Free survival (OS and PFS). Methods All consecutive patients undergoing ASCT at our center from 01/2004 to 03/2016 were evaluated. All patients received induction chemotherapy before undergoing auto-SCT. Patients received conditioning with either HDM at 200 mg/m2 (or adjusted as per renal failure) or HDM with Bortezomib (Bor-HDM). Definitions of response and progression were used according to the EBMT modified criteria. Immunoglobulin recovery was assessed at 12 months post-ASCT in those cases where immunoparesis was noted at diagnosis. Results Clinical characteristics are shown in Table 1. Decrease of uninvolved Ig's was noted in 94% of cases. At the time of analysis, 69.2% of patients are alive and 54.9% have already progressed, respectively. Median OS did not differ between patients with or without immunoparesis (p=0.851). With regards to Ig recovery at 12 months post-ASCT, median OS was longer for those patients with complete or partial normalization of Ig's compared to those with no recovery at all (Estimate median OS of 97, 77 and 69 months, respectively, p=0.008) (Fig1a). In addition, median PFS was longer for those patients with normalization or partial recovery of Ig's at 12 months post-ASCT (median of 40.3 and 38 months, compared to 24.6 months for those without Ig recovery, p=0.002) (Fig1b). Furthermore, 121 patients receiving lenalidomide maintenance were evaluated, 49% of cases exhibited complete or partial recovery of Ig's at 12 months post-ASCT, compared to 40% for those cases that were not treated with any maintenance strategy (p=0.6). In conclusion, Immunoglobulin recovery at 12 months post-ASCT is an important factor to predict for better progression-free and overall survival. The use of lenalidomide as a maintenance strategy did not seem to affect the process of Ig recovery. Based on our observations, the use of immune enhancement strategies in the post-transplant setting seem appealing and requires further investigation.

361 Background: Primitive neuroectodermal tumours (PNET) of the kidney are rare tumours with aggressive behaviour. This study was conducted to review the diagnosis and management of patients with renal PNET at our centre. Methods: This was a retrospective study conducted at a tertiary cancer care centre in Mumbai, India. The demographic and clinical data of 17 patients treated by the uro-oncology services were retrieved from electronic medical records. Descriptive analysis was performed for baseline characteristics.Overall & progression-free survival was determined using the Kaplan Meier method. Cox regression was used for multivariate analysis. Results: There were 12 male and 5 female patients in this cohort with a median age of 27 years. At diagnosis 2 patients had metastatic disease and 15 patients had non-metastatic disease. Median follow up in this cohort was 22 months (range 2-30 months). Presenting complaints were hematuria, abdominal pain, flank pain, fever, bone pain, and incidentally detected renal mass. All patients were Mic -2 positive and 13 were FLI-1 positive on immunohistochemistry. Fourteen patients underwent radical nephrectomy. One (5.9%) patient received both neoadjuvant and adjuvant chemotherapy, 8 (47.1%) received adjuvant and 2 (11.8%) received palliative chemotherapy upfront. Eight patients received adjuvant radiation to the renal bed.There was disease progression in12 patients,10 of 15 patients with non metastatic disease at diagnosis eventually developed metastasis.The median progression free survival (PFS) was 10.55 months.The pathological feature that was associated with a shorter PFS was tumor size ⩾10 cm(p = 0.044).The median overall survival was 20.04 months (95% CI 9.49 -not reached). The presence of metastasis and treatment received significantly impacted overall survival (OS). Median OS in patients with non-metastatic disease was not reached versus 14.1 months in those with metastatic disease (p = .019).The median OS in patients treated with multimodality approach was 20.11 months. Patients did not undergo surgery had a median OS of 5.45 months (p < .001) and those who did not receive any chemotherapy had a median OS of 4.57 months (p = .024).Thus, patients who received multimodality treatment had better outcomes. Conclusions: PNET kidney is an aggressive tumor which should be treated with a multimodality approach. Tumor size ⩾10 cm was an adverse prognostic factor.

Abstract Background: Advanced lung cancer inflammation index (ALI) is known to predict the overall survival of patients having some solid tumors or B-cell lymphoma. The study investigates the predictive value of ALI in multiple myeloma (MM) patients and the correlation between ALI and prognosis.Methods: A database of 269 MM consecutive patients who underwent chemotherapy between December 2011 and June 2019 in the Affiliated Hospital of Qingdao University was reviewed. ALI cut-off value calculated before the initial chemotherapy and post 4 courses treatment were identified according to the receiver operating characteristic (ROC) curve, and its association with clinical characteristics, treatment response, overall survival (OS), and progression-free survival (PFS) were assessed.Results: Patients in the low ALI group (n=147) had higher risk of β2 microglobulin elevation, more advanced ISS (International Classification System stage), and TP53 gene mutation, with significantly lower median overall survival (OS; 36.29 vs. 57.92 months, P = 0.010) and progression-free survival (PFS; 30.94 vs. 35.67 months, P = 0.013). Independent risk factors influencing the OS of MM patients were ALI (P = 0.007), extramedullary infiltration (P = 0.001), TP53 (P = 0.020), Plt (P = 0.005), and bone destruction (P = 0.024). ALI (P = 0.005), extramedullary infiltration (P = 0.004), TP53 (P = <0.001), Plt (P = 0.017), and complex chromosome karyotype (P = 0.010) were independent risk factors influencing the PFS of MM patients.Conclusions: ALI is a potential independent risk factor predicting the prognosis of newly diagnosed MM patients.

PURPOSE Melphalan flufenamide (melflufen) is a first-in-class peptide-drug conjugate that targets aminopeptidases and rapidly and selectively releases alkylating agents into tumor cells. The phase II HORIZON trial evaluated the efficacy of melflufen plus dexamethasone in relapsed and refractory multiple myeloma (RRMM), a population with an important unmet medical need. PATIENTS AND METHODS Patients with RRMM refractory to pomalidomide and/or an anti-CD38 monoclonal antibody received melflufen 40 mg intravenously on day 1 of each 28-day cycle plus once weekly oral dexamethasone at a dose of 40 mg (20 mg in patients older than 75 years). The primary end point was overall response rate (partial response or better) assessed by the investigator and confirmed by independent review. Secondary end points included duration of response, progression-free survival, overall survival, and safety. The primary analysis is complete with long-term follow-up ongoing. RESULTS Of 157 patients (median age 65 years; median five prior lines of therapy) enrolled and treated, 119 patients (76%) had triple-class–refractory disease, 55 (35%) had extramedullary disease, and 92 (59%) were refractory to previous alkylator therapy. The overall response rate was 29% in the all-treated population, with 26% in the triple-class–refractory population. In the all-treated population, median duration of response was 5.5 months, median progression-free survival was 4.2 months, and median overall survival was 11.6 months at a median follow-up of 14 months. Grade ≥ 3 treatment-emergent adverse events occurred in 96% of patients, most commonly neutropenia (79%), thrombocytopenia (76%), and anemia (43%). Pneumonia (10%) was the most common grade 3/4 nonhematologic event. Thrombocytopenia and bleeding (both grade 3/4 but fully reversible) occurred concomitantly in four patients. GI events, reported in 97 patients (62%), were predominantly grade 1/2 (93%); none were grade 4. CONCLUSION Melflufen plus dexamethasone showed clinically meaningful efficacy and a manageable safety profile in patients with heavily pretreated RRMM, including those with triple-class–refractory and extramedullary disease.

Abstract Autophagy, a degradation system, works to maintain cellular homeostasis. However, as the impact of Hepatitis C virus (HCV) infection on hepatocyte autophagy and its effect on HCV replication remain unclear, we examined them. HCV infection suppressed late-stage autophagy and increased Rubicon. siRNA-mediated knockdown of Rubicon promoted autophagy in HCV-infected cells. In Huh-7 cells harbouring the HCV replicon, Rubicon knockdown downregulated the expression of type 1 interferon (IFN)-related genes and upregulated HCV replication. Rubicon overexpression or administration of bafilomycin A1 or chloroquine, an inhibitor of late-stage autophagy, suppressed autophagy and activated the type 1 IFN pathway. On the other hand, Atg7 knockout suppressed early-stage autophagy and did not activate the type 1 IFN pathway. In livers of humanized liver chimeric mice, HCV infection increased Rubicon and enhanced type 1 IFN signalling. Elimination of HCV in the mice reduced the increase in Rubicon due to HCV infection. The expression levels of Rubicon and IFN-stimulated genes in chronic hepatitis C patients were higher than those in non-B, non-C hepatitis patients. HCV infection increased Rubicon and suppressed hepatocyte autophagy, leading to activation of the intracellular immune response. Rubicon induction is involved in HCV replication via activation of the intracellular immune response.

Aim: To define the impact of polymorphisms in genes involved in platinum-taxane and estrogen activity in the outcome of platinum-based treated ovarian cancer patients (OCP). Patients & Methods: Two hundred and thirty OCP were analyzed for 124 germ-line polymorphisms to generate a prognostic score for overall survival (OS), progression-free survival (PFS) and platinum-free interval (PFI). Results: ABCG2 rs3219191D>I, UGT1A rs10929302G>A and UGT1A rs2741045T>C polymorphisms were significantly associated with all three parameters (OS, PFS and PFI) and were used to generate a score. Patients in high-risk group had a poorer OS (hazard ratio [HR]: 1.8; 95% CI: 1.3–2.7; p = 0.0019), PFS (HR: 2.0; 95% CI: 1.4–2.9; p < 0.0001) and PFI (HR: 1.9; 95% CI: 1.4–2.8; p = 0.0002) compared with those in low-risk group. Conclusion: The prognostic-score including polymorphisms involved in drug and estrogen pathways stratifies OCP according to OS, PFS and PFI.
