Abstract BACKGROUND Glioblastoma has an infiltrative growth pattern that makes complete resection of the tumor virtually impossible. Sooner or later the tumor progresses, even after aggressive treatment with maximal safe resection, radiotherapy and/or chemotherapy. Hematological toxicity is an important cause of treatment delays during 1st line treatment. How often hematological toxicity occurs during 2nd line treatment is unclear. We explored rates of hematological toxicities in patients treated with temozolomide or lomustine at progression and investigated the association between severe toxicity during 1st and 2nd line treatment. METHODS We studied a retrospective cohort study of adult patients (n=247) with a glioblastoma treated with 2nd line alkylating chemotherapy at the Brain Tumor Center Amsterdam between 2000 and 2020. First line treatment of these patients consisted of a combination of radiotherapy combined with different treatments (80% received temozolomide, 4% PCV, 6% other chemotherapy and 10% radiotherapy only). Second line treatment consisted of temozolomide or lomustine. Mild and severe hematological toxicity were defined according to the CTCAE (version 5.0) criteria as a grade 1&2 and grade ≥3, respectively. We used descriptive statistics to analyze frequencies of hematological toxicity in patients with glioblastoma treated with 2nd line chemotherapy. RESULTS Sixty percent (147/247) of patients treated with 2nd line chemotherapy experienced hematological toxicity (grade 1–4). Considering subtypes of hematological toxicities, more patients experienced hematological toxicity during 2nd line treatment; severe thrombocytopenia occurred most frequently observed (6,1 during 1st line vs. 10,5% during 2nd line treatment), followed by neutropenia (3,6 vs. 6,9%), leukocytopenia (4,0 vs. 5,3%) and anemia (0 vs. 0,8%). Fewer patients treated with 2nd line temozolomide (n=113) experienced mild and severe hematological toxicity than patients treated with 2nd line lomustine (n=134; 46% versus 71% (for mild) and 12% vs 21% (severe toxicity), respectively). A subset of 107 patients was initially treated with radiotherapy and concurrent and adjuvant temozolomide; within this subset, patients with none or only mild toxicity during 1st line treatment had only a small risk of severe hematological toxicity during 2nd line treatment (4%). In contrast, the 34,5 % of patients with severe hematological toxicity during 1st line treatment also experienced severe hematological toxicity during 2nd line alkylating chemotherapy. CONCLUSION Hematological toxicity occurs more frequently during 2nd line treatment. Treatment with 2nd line temozolomide results in less hematological toxicity than lomustine. Absence of severe toxicity during 1st line treatment is predictive for the risk of toxicity during 2nd line treatment.

Abstract Introduction Indolent lymphomas represent 40% of all subtypes of non-Hodking's lymphoma, of which follicular lymphoma (FL) is the most frequent. Bendamustine is a dual alkylating agent with demonstrated high efficacy and low toxicity profile in reported clinical trials. We present the preliminary results from the experience of Spanish compassionate use registry of this agent as first-line treatment for indolent lymphoma. Methods Retrospective multicenter analysis of patients with indolent non-Hodgkin lymphomas (iNHL) treated as frontline with Bendamustine plus Rituximab (BR) in compassionate use. Clinical efficacy was evaluated according to Cheson criteria (2007) and toxicity according to CTCAE v3.0 scale. This study has been approved by local ethical committees. Results Patients’ characteristics: There are 96 patients registered (9 centers), with the following diagnoses: FL: 62 (64.5%), marginal zone 24 (25%), Waldenström macroglobulinemia 7 (7.3%) and mantle NHL 3 (3.1%). The main clinical features of the series are: 45% males, median age 64 years (range 36-84), 87.1% ECOG≤ 1, 63% Ann Arbor stage IV, 50.5% high risk FLIPI and 43.7% CIRS ≥ 4. Extranodal involvement was present in 79.1% of the patients, bone marrow  involvement in 52% and 11 patients (11.9%) had bulky disease. Treatment consisted in 6 cycles of BR (B-90 mg/m2 D1-2, R-375mg/m2 D1) in 95% patients. Median number of cycles administrated was 6 (range 1-8). G-CSF support was administered in 16.1% of cycles. Response and Safety: Overall response rate was 95%, with 65.5 % CR, 13.1% uCR and 16.4% PR in the 61 evaluable patients. Progression was documented in 4.9% of patients. Three exitus ocurred due to aspergillosis, progression and other not related with LNH. Median follow-up period was 14 months (3-47). In general, treatment was well tolerated; over 461 cycles registered, the most common adverse event was hematological toxicity with grade 3-4 neutropenia in 10.4%, grade 3-4 leucocitopenia in 6.9% and grade 3-4 anemia in 1.9% of the cycles. Other toxicities included all grades infections in 3.2% of patients, gastrointestinal in 3.4%, asthenia in 3.2%, chills in 1.1%, and mucositis 0.4%. Only 9 hospitalizations due to febrile neutropenia were reported. Conclusion Bendamustine plus rituximab was an effective and well tolerated regimen for newly diagnosed patients with indolent NHL. Disclosures: No relevant conflicts of interest to declare.

1581 Background: The use of cytotoxic drugs concurrent with RT represents a promising approach in the combined treatment of malignant gliomas. Gemcitabine (dFdCyd) is a drug widely explored for its potential radiomimetic activity in different tumors. The present study was aimed to evaluate the dose-limiting toxicity (DLT) and maximum tolerated dose (MTD) of weekly prolonged dFdCyd infusion, administered in combination with RT as first line treatment, in adult pts affected by supratentorial GBM. Methods: Within 6 weeks after surgery, in the presence of measurable residual disease and KPS >70, pts were treated with fractionated RT at a dose of 2.0 Gy/daily fractions, 5 days a week (global dose 60 Gy). From 24 to 72 hours before the first RT application, and afterwards once weekly, pts received concurrent dFdCyd, at fixed dose rate of 10 mg/m2/min, over a total period of six weeks. Planned dose levels of dFdCyd started from 200 mg/m2/weekly (level 1), with sequential steps of 25 mg/m2/w based on toxicity. Results: Ten pts were enrolled into the study: six were male, median age 55.2 years (range 44–75), with a median KPS at baseline of 85 (SD 9.71). The median time from diagnosis to the start of treatment was six weeks (range 4–7). The median RT duration was 6 weeks (range 4–7), all but one pt received the planned dose and all pts received concomitant CT. Four pts entered at Level 1; one pt was excluded from the study, due to rapid progressive disease during the treatment. Two of the three valuable pts presented a relevant neurological worsening; on this basis the dFdCyd dose was reduced to 175 mg/m2/w (Level -1). A total of six pts were entered at Level -1, and none of them reported DLT. No hematological grade 3–4 toxicity was reported. Grade 3 non-hematological toxicity was observed in one pt (transaminases increase). After a median follow-up of 13.4 months (range 3–24), the median progression-free survival was 8 months (CI 95% 1–18), and the median overall survival was 14 months (CI 95% 12–17). Conclusions: The recommended dose of prolonged infusion of dFdCyd concomitant with RT is 175 mg/m2/w. The observed activity has been considered interesting enough to support a phase II study of this concurrent CT-RT schedule as first line treatment in GBM. [Table: see text]

e16151 Background: IV NVB plus hydrocortisone (HC) compared with HC alone resulted in improved clinical benefit, progression-free survival (PFS) and PSA response rate in HRPC. The oral formulation of NVB avoids the side effects associated with the IV injection, may reduce administration and toxicity-related costs and is easy to administer. Due to these advantages, single agent oral NVB treatment could be considered as an optimal option for patients (p) with HRPC previously treated with a taxane or as first-line treatment when a taxane is not indicated. We retrospectively evaluated efficacy and toxicity or oral NVB administered as single agent as first or second-line chemotherapy of metastatic HRPC. Methods: Retrospectively data was collected from p with metastatic HRPC treated with oral NVB 80 mg/m2 days 1 and 8, with a prior test of myelosensitivity at 60 mg/m2 for the first cycle, plus prednisone 10 mg/day. Patients had received a taxane as first-line treatment or had a documented contraindication to receiving docetaxel. 1 cycle was equivalent to a 3-week period. Results: Data on 55 p treated in 11 Spanish centres were included for assessment. Median age was 72.5 years (range 54–86). ECOG PS 0, 17%; 1, 66%; 2, 17%. Median PSA 75 ng/mL. Prior taxane chemotherapy, 87%. Median number of cycles was 4 (range 1–6). 53.8% of p could escalate oral NVB to 80 mg/m2. 221 cycles were performed, 4.1% were delayed and 3.2% had a dose reduction. Grade 3–4 events were infrequent and mainly haematological: neutropenia (5.5% of p), anemia (3.6%), pain (3.6%), infection (1.8%), asthenia (1.8%), respiratory (1.8%). No febrile neutropenia was reported. 49 p were evaluable for PSA response rate; complete plus partial response was observed in 20.4% (95% CI: 10.2% - 34.3%) and PSA stable was reported in 40.8%. 29 p were evaluable for measurable disease; among them, 20.7% presented partial response and 44.8% stable disease. Median follow-up was 4.3 months. Survival status: 49 p (89.1%) are alive and 6 p (10.9%) died. Conclusions: Oral NVB is a safe and active regimen in previous chemotherapy treated HRPC. For those p who can not receive a taxane as first-line therapy, oral NVB can also be considered as an effective first-line treatment. No significant financial relationships to disclose.

Patients had received either a taxane as 1st-line treatment or had a documented contraindication to receiving docetaxel. 1 cy was equivalent to a 3-week period. Results: Data on 67 p treated in 13 Spanish centres were included. Median age 73 years (range 54-86). ECOG PS 0, 16.4%; 1, 56.7%; 2, 11.9%. Median PSA 88.9 ng/mL. Prior chemotherapy, 58.2%.

No febrile neutropenia was reported. PSA response rate 16.1%, PSA stable was reported in 41.9%. 39 p were evaluable for measurable disease; among them, PR 17.9%, SD 48.7%. Median follow-up, 7.1 months. Median overall survival, 11 months [95% CI: 7.3-14.7]. Median PFS, 2.9 months [95% CI: 2.2-3.6]. Conclusions: NVBO is a safe and active regimen in previous chemotherapy treated HRPC. For those p who cannot receive a taxane as first-line therapy, NVBO can also be considered as an effective first-line treatment.

e19001 Background: A recent phase III clinical trial, EURTAC, demonstrated that first-line treatment with erlotinib significantly improved progression-free survival (PFS) compared with standard chemotherapy in advanced non-small cell lung cancer (NSCLC) patients whose tumors harbored epidermal growth factor receptor (EGFR) mutations (Rosell 2012). We sought to estimate the cost-utility of treatment with erlotinib in this patient population from the US payer perspective. Methods: We developed a Markov model with three health states: PFS, progression, and death. Patients received treatment until progression, unacceptable toxicity or death; patients randomized to chemotherapy received a maximum of 4 treatment cycles. Transition probabilities were extrapolated from the trial. Median PFS was 9.7 months in patients receiving erlotinib and 5.2 months in patients receiving chemotherapy (p<0.0001). Cost and utility data were obtained from the literature. Probabilistic sensitivity analysis (PSA) was performed to assess uncertainty. We evaluated two scenarios: 1) first-line erlotinib vs. first-line chemotherapy, and 2) first-line erlotinib and mixed second-line treatments vs. first-line chemotherapy and second-line erlotinib. Results: First-line treatment with erlotinib vs. chemotherapy resulted in an increase of 0.60 life-years or 0.44 quality-adjusted life-years (QALYs). Mean total costs were $59,300 in the erlotinib arm and $17,800 in the chemotherapy arm, yielding an incremental cost-effectiveness ratio (ICER) of $98,338 with a 53% probability of being cost-effective at a willingness to pay (WTP) of $100,000/QALY. In the second scenario, the ICER was $50,002/QALY, with a 66% probability of being cost-effective. The main cost drivers in the model were the time spent in the PFS health state and drug costs. Conclusions: Treatment with erlotinib in first-line EGFR-positive NSCLC results in increased costs but also substantial increases in QALYs, demonstrating that this personalized approached to treatment may be cost-effective.

335 Background: Perioperative cisplatin based chemotherapy (PCBC) is a standard of care in the management of muscle invasive urothelial carcinoma (UC). Cisplatin based (C) therapy also represents the historical first line treatment of metastatic disease. There is however no data to guide the optimal choice of first line chemotherapy regimen – C re-treatment vs other second-line or non cisplatin regimens (NC) –in UC patients who relapse after receiving PCBC. This multicenter retrospective study compares C vs NC first line treatment on progression-free survival (PFS) for patients (pts) with advanced UC after PCBC and cystectomy. Methods: Data were collected for patients who received various first-line chemotherapies for advanced UC following previous PCBC therapy. Cox proportional hazards models were used to investigate the prognostic ability of type of peri-operative / first-line chemotherapy, visceral metastasis, ECOG status, time from prior chemotherapy (TFPC), anemia, leukocytosis and albumin on PFS. Results: Data were available for 145 pts from 12 centers. The mean age was 62 years, 113 (77.9%) were men and ECOG-PS was 0 or >0 in 74 (51.0%) and 61 (42.0%) patients. Ninety-one (62.8%) pts received C first line, the median number of cycles was 4 (range 1-17) and the median TFPC was 6.2 months (range 1-154). Median overall survival was 86 weeks (95% CI 70-106) and median PFS was 24 (95% CI 18-27) weeks. Time from perioperative chemotherapy (TFPC) (>52 weeks vs ≤52 weeks; HR 0.63 p=0.027) and ECOG-PS at first line (1+ vs 0; HR 1.73 p=0.010), were prognostic of PFS. No significant effect was noted for C vs NC first line (p=0.70); however, among patients with TFPC >52 weeks, patients with NC had worse PFS (median 4.6 months, 95% CI 1.8-12.2) than those who received C (median 8.1, 95% CI 3.2-16.3). Conclusions: There is no evidence to suggest overall superiority of C vs NC based first line chemotherapy or a second-line regimen in patients with advanced UC who received prior PCBC. However, those with TFPC >52 weeks should probably receive C first line chemotherapy given better PFS with C.

Background/Aim: The current standard of care for first-line treatment of locally advanced or metastatic urothelial carcinoma (UC) is platinum-based combination chemotherapy. Recently, immune checkpoint inhibitors have been reported to be effective for UC. Knowing whether immunotherapy or chemotherapy is suitable as first-line treatment is beneficial for patients. A retrospective study was conducted on the clinical outcomes of Japanese patients who received three or more courses of first-line chemotherapy for metastatic UC to assess the outcome of conventional treatments in real clinical situation. Patients and Methods: Patients who received first-line chemotherapy between August 2009 and December 2019 were included. Progression-free survival (PFS) and overall survival (OS) were assessed. Results: The median PFS and OS were 7.1 and 27.1 months, respectively, for patients with no disease progression at the end of three courses. Of 28 patients, 25 (89.3%) received second-line drug therapy and 10 (35.7%) received focal therapy for disease control. Patients with focal therapy had significantly longer OS than those without focal therapy (p=0.019, log-rank test). Conclusion: OS of metastatic UC at our Institution is relatively long, suggesting that aggressive second-line drug therapy and focal therapy may have contributed to such result.
