e19527 Background: Palliative chemotherapy (CT) is given with the goals of palliating cancer symptoms and prolonging life. Patients with a poor performance status (PS) generally derive less benefit from CT and may experience greater toxicity. Advanced cancer patients admitted to hospital generally have a poor PS, and yet palliative CT is often administered to hospitalized patients. The evidence to support palliative CT in hospitalized patients is scarce. We hypothesize that palliative in-patient CT does not result in meaningful clinical benefit. Methods: With ethics approval, a retrospective chart review was undertaken to report outcomes from in-patient CT at the Ottawa Hospital Cancer Centre between April 2008- January 2010. From hospital pharmacy records, all advanced solid tumor patients receiving in-patient palliative CT were identified. Patients receiving radical, curative, neo- or adjuvant therapy, or those admitted for an inpatient regimen, were excluded. The primary endpoints were overall survival following CT, place of discharge from hospital, and whether further CT was received. Results: We report 199 in-patients (23% breast cancer, 22% small cell lung cancer, 16% NSCLC, 39% other) who received CT (median 1 cycle, range 1-5) during the study period. The median age was 61 (range 19-88); 59% were female. The main reasons for hospital admission were dyspnea (31%) or pain (29%). At baseline 25% were anemic, 36% had leucocytosis and 70% were hypoalbuminemic (<30g/l). 67% were receiving 1st line CT. The median overall survival was 4.5 months (95% CI: 3.2 - 5.8). Longest survival was seen in SCLC patients (7.3m). 77% of patients were discharged home, but 17% died during the admission. 72% of patients received further systemic therapy. Factors significantly associated with shorter survival were hypoalbuminemia (HR 1.52, 95% CI 1.06- 2.18, p=0.02), and therapy in 2nd line or beyond (HR 2.10, [1.37-3.23], p<0.001). Receiving treatment beyond 1st line, and baseline leucocytosis, were both significantly associated with patients being less likely to be discharged home or receive further CT. Conclusions: While in-patient palliative CT is associated with short survival, many patients remain well enough to be discharged home and receive further therapy.

Background: Traditionally, children with AML undergo аllo-HSCT with myeloablative conditioning (MAC). It is known that MAC is associated with significant transplant-related morbidity and mortality. Reduced-intensity conditioning (RIC) is used in patients not eligible for conventional conditioning therapy due to poor performance status and severe toxic complications after previous chemotherapy. RIC is a well-established treatment strategy in adult patients with comorbidities. But there is no conclusive evidence to support efficacy of RIC allo-HSCT in children suffering from different malignant diseases including AML. The aim: To compare efficacy of different intensity conditioning regimens in children with high risk (HR) AML (according to AML-BFM protocols 1998 and 2004) and to identify factors which have a prognostic significance for overall survival (OS). Patients and methods: Retrospective analysis was performed in 192 patients (pts) with AML (median age of 10 years (0.5-18 y.o.), who received allo-HSCT at R.M. Gorbacheva Research Institute between 08/2000 and 09/2019. MAC (busulfan- or treosulfan-based) were used in 109 pts: 1st CR - 46 pts (MRD+ n=11), 2nd CR - 18 pts, 3rd CR - 1 pt, relapse - 44 pts. Allo-HSCT with RIC were performed in 83 pts: 1st CR - 32 pts (MRD+ n=13), 2nd CR -19 pts, 3rd CR - 4 pts, relapse -28 pts (p=0,674). RIC consisted of fludarabine (30 mg/m2/d x 5 days) + melphalan (70 mg/m2/d x 2 days) or fludarabine (30 mg/m2/d x 5 days) + busulfan (4 mg/kg/d x 2 days). Indication for RIC allo-HSCT was poor performance status (Lansky/Karnofsky score ≤70%), or organ dysfunction due to previous therapy, or infectious complications at the moment of allo-HSCT. Allo-HSCT from matched related donor was performed in 30 pts (16%), from matched unrelated donor - in 98 pts (51%), haploidentical - in 64 pts (33%) and the donor distribution was not different between groups (p=0,878). Post-transplant Cy was included in GVHD prophylaxis regimens in 102 pts (53%). OS were estimated using Kaplan-Meier curves. Univariate analyses were performed using the log rank test for OS, Grey test for cumulative incidences. Multivariate analyses were performed using the Cox proportional-hazard model. Results: Median follow-up was 5 years for МАС, 4.5 years for RIC. In both groups the median time to neutrophil engraftment &gt;=0,5x109/l was D+16 (range D+8-52). Engraftment was observed in 67 pts (81%) after RIC and 94 pts (86%) after MAC (p=0,231). OS after RIC allo-HSCT in the 1st CR was 76% and after MAC - 68% (p=0,014), in 2nd CR 50% after RIC and 54% after MAC (p=0,058), in advanced disease 14% after RIC and 16% after MAC (p=0,394). The transplant-related mortality rate was 19% after RIC and 22% after MAC (p=0,546). Risk of relapse was 28% after RIC and 26% after MAC (p=0,456). Factors influencing OS after MAC were: 1) Remission status at the moment of allo-HSCT (р=0.001); 2) Presence of aGVHD grade I-II (р=0,005); 3) Relapse or MRD+ status after allo-HSCT (р=0.012); 4) Lansky score &gt;70% (р=0,024). Factors influencing OS after RIC were: 1) Remission status at the moment of allo-HSCT (1st remission) (p=0,001); 2) Lansky score &gt;70% (р=0,004). Conclusion: The effectiveness of RIC and MAC is comparable in children with HR AML, but RIC demonstrated better results in 1st CR. The presence of I-II grade aGVHD had positive effect in MAC. Factors influencing OS in both groups were disease status at the moment of allo-HSCT and performance status before allo-HSCT The use of RIC can be effective in patients, especially those who have undergone allo-HSCT in the 1st remission, while minimizing regimen-related toxicity in children who have undergone previous intensive treatment. Multicenter studies are warranted, especially for patients in the first CR, where long-term complications are of most importance. Disclosures No relevant conflicts of interest to declare.

18116 Background: Several studies have demonstrated that the combination of CBDCA plus GEM according to various regimens appears as effective as cisplatin (CP) containing regimens. CBDCA plus GEM regimens are associated with more haematological toxicity (G3–4 leucopenia 17–40.6%, G3–4 neutropenia 29–75%, G3–4 thrombocytopenia 21–57% and G3–4 anaemia 5–33%), but with lower non-hematological toxicity as compared to CP-based regimens. Methods: The primary objective of this trial was the evaluation of the overall survival, while the secondary objectives were assessment of objective response and toxicity in elderly or poor PS pts. The eligible pts had previously untreated aNSCLC not suitable for CP-based chemotherapy. Pts received each at 3-week intervals GEM 1000 mg/sq on day 1 and 8 plus CBDCA area under the curve of 5 on day 2. Between April 2004 and January 2007, 54 consecutive pts were accrued in the study. Pt characteristics were: 42 (78%) males and 12 (22%) females; median age 72 years (range: 56–84 years) with 67% of pts = 70 years; median Karnofsky PS 90 (range: 50–100) with 33% of pts = 80; stage disease: IIB not suitable for surgery in 1 (2%) pt, IIIA in 5 (9%), IIIB in 10 (19%), IV in 33 (61%) and recurrent disease in 5 (9%); histologic subtype: adenocarcinoma in 30 (56%) pts, epidermoid in 11 (20%), bronchioalveolar carcinoma in 2 (4%) and other histologic subtypes in 11 (20%). Results: A median of 4 courses was administered (range 1–8). Dose- intensity was 98.7% (range 50–100%) for CBDCA and 87.2% (range 60–100%) for GEM. Objective response according to intention-to-treat analysis was as follows: 15 (28%) pts had PR, 16 (29%) had SD, 14 (27%) had PD and 9 (16%) were not assessable because lost to follow-up or too early. Median overall survival was 10 months. WHO G3 leucopenia was observed in 5 (9%) pts, G3–4 neutropenia in 15 (28%), G3 thrombocytopenia in 7 (13%) and G3 anaemia in 2 (4%). No WHO G3–4 non-hematological toxicity was observed. Conclusions: This regimen is feasible and active in elderly or poor PS pts. It can be administered in a outpatient setting because toxicity is moderate and manageable. No significant financial relationships to disclose.

534 Background: The management of patients with poor performance status (PS) remains challenging in the absence of data on optimal treatment. Here we assessed the treatment and outcomes of patients with metastatic colorectal cancer (mCRC) with poor Eastern Cooperative Oncology Group (ECOG) PS (≥ 2) in routine clinical care. Methods: Analysis of patients prospectively entered onto the TRACC (Treatment of Recurrent and Advanced Colorectal Cancer) database, a clinician-designed initiative to collect comprehensive data on consecutive patients with mCRC from sites across Australia. Data collection commenced in July 2009 and is ongoing at 14 participating public and private centres. Results: Of the 679 patients entered, 129 (19.0%) had an ECOG PS ≥ 2. In total, 77 (11.3%) were PS 2, 41 (6.0%) PS 3 and 11 (1.6%) PS 4. Chemotherapy was administered to 55 (71.4%) PS 2 and 15 (36.6%) PS 3 patients, with none of the PS 4 patients being treated. Overall, poor PS patients were significantly less likely to receive any chemotherapy compared to their good PS (PS 0-1) counterparts (55.0% versus 86.8%, p<0.0001) and, when chemotherapy was given, significantly less likely to receive combination chemotherapy (38.0% vs 71.6%, p<0.0001) or bevacizumab (15.5% vs 46.9%, p<0.0001). Overall survival (OS) was reduced with declining PS, with medians of 31.2, 9.0, 3.0 and 0.8 months for PS 0-1, 2, 3 and 4 patients respectively (p<0.0001). Poor PS patients treated with chemotherapy had a better OS outcome (9.8 vs 4.1 months for untreated patients, p<0.0001). At one and two years, 22 (31.4%) and 8 (11.4%) treated poor PS patients were alive. Conclusions: In routine practice many patients with a poor PS, particularly those that are PS 2, receive active treatment. Although overall survival for poor PS patients is poor, some patients appear to benefit from treatment. Further data analysis, particularly to define subsets that may benefit most from treatment, is planned as further sites around Australia contribute data to the project.

349 Background: GB cancer is a common cancer in northern India. Gem-P is currently the standard of care for pts with advanced biliary tract cancers based on the ABC02 study which had 61 pts with GB cancer with a clinical benefit rate (CR+PR+SD) of 85%. Indian patients have a higher risk disease and present at a more advanced stage than in the West and data on treatment is lacking. Methods: This is retrospective analysis of the prospectively maintained database of 131 pts with advanced GB cancer treated at TMC between Jan 2012-May 2013. Aim of the study is to assess the clinical benefit rate in this group of pts with the Gem-P. Pts received cisplatin 25 mg/m2 and gemcitabine 1000 mg/m2 on D1 and D8 of a 21day cycle, for gem-oxaliplatin, pts received gemcitabine 1000mg/m2 on D1 and oxaliplatin 100mg/m2 on D2 every 14 days. Response was assessed after 3-4 cycles. Results: Of the 131 patients, 110 pts were treated with Gem-P (95 oxaliplatin, 15 cisplatin; 1 received cetuximab-Gem-P) and 21 (16%) pts received best supportive care alone in view of poor performance status and deranged organ function. Median age was 53 years (range, 27-76), 82F/49 M; median CA19.9 206 (<2-2251660); median CEA 6.9 (0.8-3541); site of metastases was liver in 66 (50%), nodal in 74(56%), peritoneal in 29(22%) and bilateral ovarian in 5(3.8%) patients. Of the 110 pts treated with GEM-P, PS was 0-1 in 91% of patients; median number of cycles received was 4 (1-12); grade 3 &4 toxicities were- thrombocytpenia-12 (11%), neutropenia -2 (2%), hepatitis -2 (2%) patients, neuropathy-4 (4%) and diarrhea-8 (7.2%). 86/110 (78%) were evaluable for response out of which 4 (5%) had CR, 31(36%) had PR, 13(15%) had SD, and 38 (44%) had progressive disease. 32/110 (29%) pts received 2nd-line chemotherapy (majority capecitabine -irinotecan based). Conclusions: This is the single largest study to show tolerance and efficacy of Gem-P in Indian pts with advanced GB cancer. Compared to the ABC 02 study, the clinical benefit rate is low at 56% suggesting that the biology of advanced GB cancers in Indian pts is likely to be aggressive and needs to be studied in prospectively designed studies.

391 Background: Nivolumab has changed the treatment of advanced gastric cancer (AGC). Nivolumab shows better outcome compared to best supportive care in AGC patients who received at least two prior regimen. Although there is not reliable date of poor performance status(PS) AGC patients who received nivolumab. We investigated efficacy and safety of nivolumab for AGC patients with poor PS. Methods: We retrospectively collected clinicopathologic data from patients with AGC who received nivolumab monotherapy in Himeji Red Cross Hospital from October 2017 to June 2019. Results: 49 AGC patients who received nivolumab were analyzed. 27 patients were PS 0 or 1(Good Group), and 22 patients were PS 2 or 3(Poor Group). Median progression free survival and overall survival was 61 days and 180 days in Good Group and 36 days and 85 days in Poor Group. Overall survival (OS) was significantly shorter in Poor group(180 days vs 85 days, p = 0.0255). Disease control rate was 23% in Good group and 9% in Poor group. 33% patients were experienced immune related adverse event (iRAE) in Good Group, and 18% in Poor Group. We investigated prognostic factor of OS in Poor Group such as Royal Marsden Hospital Score(RMH score), modified Glasgow prognostic score(mGPS), and Japan Clinical Oncology Group (JCOG) prognostic index. RMH score and JCOG prognostic index good or moderate group was significantly longer overall survival than poor group (93 days vs 35 days (p = 0.0214)). JCOG prognostic index was most correlated with OS among these tools. Conclusions: This study suggested that nivolumab has a modest effect and is feasible as third line or later line for AGC patients. JCOG prognostic index was suggested to be effective in predicting prognosis in AGC patients who received nivolumab.

Abstract Between January 2001 and June 2005 a prospective cohort study of hospitalized patients with hematological malignancies including 47 adults and 30 children with candidemia was conducted at a tertiary oncology care center in Brazil in order to compare the epidemiological characteristics, concurrent illnesses and the clinical microbiological data of both groups that may influence the outcome. The crude mortality was higher in the adult population than in children (46,8% vs. 20,0%) (figure 1). A univariate analysis indicated that in the adult population were lymphoma, neutropenia, presence of comorbidities, a non-removed central venous catheter (CVC), a poor performance status, lack of CVC, use of steroid, hepatic dysfunction, previous surgery, hypotension and severe respiratory dysfunction were risk factors significantly associated with death. Among children the predictors of mortality were acute leukemia, neutropenia, presence of comorbidities, lack of CVC, poor performance status, hypotension, concomitant infected sites, pulmonary infiltrates and severe respiratory dysfunction. Although no major differences was detected in survival rates following fungemia with C. albicans and all Candida non-albicans species, episodes with Candida glabrata, krusei and tropicalis subgroup species had the highest crude death rate compared with C. albicans and other isolates (59,4% vs. 35,3% vs. 10,7%; P&lt;0.01) (figure 2). Candidemia due to C. parapsilosis was associated with the lowest mortality rate. Two variables remained statistically associated with mortality among adults in the multivariate analysis: CVC retention (OR 6.41; 95% CI 1.04–39.55) and presence of comorbidities (OR 2.17; 95% CI 1.33–3.53). Among children only the presence of comorbidities (OR 2.61; 95% CI 1.46–4.66) affected independently the outcome. Our data demonstrate children had a significant lower mortality rate than adults, despite the higher incidence of candidemia in this lower age subjects. There were significant differences of epidemiological, clinical characteristics and other risk factors between both groups. Concurrent comorbidities were the most important independent prognostic factor in both groups of patients.

Abstract Background The aim of this study is to identify risk factors associated with the development of severe bacterial infection (SBI) in patient with multiple myeloma (MM) during treatment with bortezomib-containing regimens. Methods A total of 98 patients with MM who were treated with bortezomib-based treatment between 2006 and 2012 were analyzed. Fifty three patients received bortezomib-dexamethasone, 25 patients received bortezomib-melphalan-prednisolone, 15 patients received bortezomib-doxorubicin-dexamethasone and 5 patients received other regimens. They received a total of 427 courses of treatment. The SBI was defined as at least grade 3 neutropenic/non-neutropenic infection by NCI Common Terminology Criteria for Adverse Events version 4.0. Using the logistic regression method, we analyzed risk factors for the development of SBI during each course of treatment. Results Median age of the patients was 62 years and 40.6% (30/98) of patients treated with bortezomib-containing regimens as first-line therapy. The SBI was developed in 57% (56/98) of patients and 19% (81/427) of bortezomib courses. Among 81 episodes of SBI, 42 (53%) episodes were clinically documented infection, 30 (37%) were microbiologically documented infections, and 9 (11%) were fever of unknown origin. The most common type of infection was pneumonia (60%). Poor performance status (ECOG ≥2) (Hazard Ratio [HR] 5.365, 95% Confidence Interval [CI] 2.004-14.364, P =.001) was the only risk factor for the development of SBI in 98 patients. When we analyzed the risk factors for the development of SBI which occurred during each treatment course, poor performance status (ECOG ≥2) (P <.001), early course of treatment (≤2 courses) (P <.001) and pretreatment lymphopenia (absolute lymphocyte count <1.0 x 109/L) (P = .043) were associated with increased risk for developing SBI in each course. These 3 risk factors remained independently significant in multivariate analysis: poor performance status (ECOG ≥2) (HR 3.920, 95% CI 2.305-6.666, P <.001), early course of treatment (≤2 courses) (HR 2.782, 95% CI 1.633-4.740, P <.001) and pretreatment lymphopenia (HR 1.728, 95% CI 1.016-2.937, P = .043). The probability of developing SBI in each treatment course was 5.1% in courses with no risk factor, 14.9% in 1 risk factor, 23.9% in 2 risk factors and 59.5% in 3 risk factors (P <.001, Figure 1). After treatment with bortezomib-containing regimens, patients who experienced SBI showed a significantly shorter overall survival than patients who didn't experienced SBI (median 6.1 month vs. 30.1 months, P = .004) although progression free survival was not different (median 18.1 months vs. 21.9 months, P = .418). The multivariate cox analysis demonstrated that the development of SBI was associated with inferior overall survival (HR 2.440, 95% CI 1.305-4.561, P = .005) as well as male sex (HR 2.323, 95% CI 1.236-4.367, P = .009). Conclusions In conclusion, we identified that poor performance status, early courses of treatment, and lymphopenia at the beginning of each treatment course were the risk factors for the development of SBI in patients with MM during treatment with bortezomib-containing regimens. Close monitoring for the development of SBI and appropriate treatment should be considered in the patients with risk factors. Disclosures: No relevant conflicts of interest to declare.

Abstract Purpose There is limited information on treatment recommendations for glioblastoma patients with poor performance status. Here, we aim to evaluate the association of radiotherapy on survival in glioblastoma patients presenting with poor postoperative performance status in first-line setting. Methods We retrospectively analyzed data of 93 glioblastoma patients presenting with poor postoperative performance status (ECOG 2–4) at the University Hospital Zurich, Switzerland, in the years 2005–2019. A total of 43 patients received radiotherapy with or without systemic therapy in the first-line setting, whereas 50 patients received no additive local or systemic treatment after initial biopsy or resection. Overall survival was calculated from primary diagnosis and from the end of radiotherapy. In addition, factors influencing survival were analyzed. Results Median overall survival from primary diagnosis was 6.2 months in the radiotherapy group (95% CI 6.2–14.8 weeks, range 2–149 weeks) and 2.3 months in the group without additive treatment (95% CI 1.3–7.4 weeks, range 0–28 weeks) (p < 0.001). This survival benefit was confirmed by landmark analyses. Factors associated with overall survival were extent of resection and administration of radiotherapy with or without systemic treatment. Median survival from end of radiotherapy was 3 months (95% CI 4.3–21.7 weeks, range 0–72 weeks), with 25.6% (n = 11) early termination of treatment and 83.7% (n = 36) requiring radiotherapy as in-patients. Performance status improved in 27.9% (n = 12) of patients after radiotherapy. Conclusion In this retrospective single-institution analysis, radiotherapy improved overall survival in patients with poor performance status, especially in patients who were amendable to neurosurgical resection.
