e21520 Background: Common treatment for patients with unresectable relapsed uterine sarcoma is anthracycline-based combination chemothersapy, but the response is not satisfactory. We evaluated the effects of temozolomide combined with bevacizumab in patients with relapsed uterine sarcoma. Methods: From 2009 to 2012, nine patients with relapsed uterine sarcoma were treated with weekly bevacizumab (2mg/kg; days1,8, and 15, q4 weeks) and temozolamide (80mg/body, daily), and treatment continued until disease progression. The response and adverse effects were evaluated using the response evaluation criteria in solid tumors (RECIST), and common terminology criteria for adverse events (CTCAE) version 3.0. Results: In RECIST evaluation, 1 (11%) of 9 patients had complete response (CR) and 1 (11%) had partial response (PR). Four patients (44%) had stable disease (SD) for at least three months. The response rate (RR; CR+PR) and clinical benefit rate (CBR; CR+PR+SD) were 22% and 66%, respectively. The median progression-free survival was 9.8 months (range from 3 to 32 months). There were no treatment-related deaths or CTCAE grade 4 toxicities, and no patients were dose-reduced due to toxicity. Conclusions: Temozolomide combined with bevacizumab provided disease stabilization in some patients with relapsed uterine sarcoma with tolerable toxicities. These results suggested that this combination would offer another option in the treatment of unresectable relapsed uterine sarcoma.

3080 Background: ATB exposure is proven to worsen response and survival in immunotherapy recipients. However, its influence on outcomes from CIT is currently undefined. Methods: We conducted a retrospective, multi-centre observational study including 77 mNSCLC patients who received pembrolizumab, pemetrexed and carboplatin CIT as first-line therapy for mNSCLC, between December 1, 2018 and January 1, 2020 in 3 academic referral centres in Europe and in the United States. We documented ATB exposure in the 30 days prior to CIT commencement (pATB) or concurrently (cATB) until CIT cessation. Outcome measures included overall (OS) and progression-free survival (PFS) calculated from commencement of CIT, and overall response rates (ORR) defined by Response Evaluation Criteria in Solid Tumors (v1.1). Results: We enrolled 77 patients, 41 of whom were female (n = 53%) with adenocarcinoma (n = 73, 95%), performance status (PS) 0-1 (n = 69, 90%) PD-L1 Tumour Proportion Score < 50 (n = 57, 74%). Median OS was 16.4 months (95%CI 8.4-24.4), median PFS was 6.7 months (95%CI 5.7-7.6). ORR was 48% including 1 complete (1%) and 36 partial responses (47%). Eleven patients (14%) received pATB, with penicillin/cephalosporins (p/c, n = 7, 63%) for <7 days (n = 10, 90%). Thirty-five patients (45%) received cATB with p/c (n = 11, 40%) for <7 days (n = 28, 80%). Most common indication for ATB was peri-procedure prophylaxis in pATB (n = 7, 63%) and suspected febrile neutropenia in cATB (n = 14, 40%). pATB (p = 0.004) but not cATB (p = 0.85) predicted for worse OS (19.6 vs 6.5 months, Hazard Ratio [HR] 2.9 95%CI 1.3-6.3). Neither pATB nor cATB predicted for PFS or ORR (p > 0.05). Multivariable analyses confirmed pATB (HR 2.3 95%CI 1.1-5.5, p = 0.05) to predict for OS independent of PD-L1 status, PS and cATB. pATB+/- groups were balanced with regards to age, gender, PS nor PD-L1 status (p > 0.05). Conclusions: Whilst cATB does not compromise outcome from CIT, this study reproduces the detrimental effects observed for pATB exposure in immunotherapy recipients. Mechanistic verification of the immune-biologic foundations underlying this association is urgently warranted.

11056 Background: Uterine leiomyosarcomas (ULMs) tend to recur regardless of their stage, and there is no satisfactory report for relapsed ULMs. Temozolomide (T) is derivatives of dacarbazin and these agents have been used for treatment of ULMs. ULMs has a plenty of vessels compared to uterine myoma so that bevacizumab (B) was used in ULMs. In the present study, we evaluated the effect of TB in heavily pretreated relapsed ULMs. Methods: From 2009 to 2016, total 19 patients (pts) with heavily pretreated ULMs were enrolled. Patients were treated with T (80mg/body/day) and B (2mg/kg; days 1, 8 and 15, q4 weeks). Treatment was continued until disease progression and/or unmanageable toxicities. Response was evaluated with the response evaluation criteria in solid tumors (RECIST) v1.1, and adverse effect (AE) was assessed by common terminology criteria for adverse events (CTCAE) v4.0. Results: Seventeen of 19 pts were subjected to response evaluation. Median age of pts was 56.3 years (range: 31-69). Three pts (18%) had complete response (CR), 2 (12%) had partial response, and 7 (41%) had stable disease (SD). The response rate (RR: CR+PR) and clinical benefit rate (CBR: CR+PR+SD) were 29% and 71%. The median progression-free survival was 14.2 months (range: 0-89). Median administration cycle was 9.5 (range: 2-48). AE with grade 3 and more over were observed in 6 pts. There was one dead case from perforation, but toxicity was almost manageable. Conclusions: We experienced 3 cases of CR, and two of them had CR for more than two years. Intriguingly, TB could be substantially effective even in relapsed patients with heavily pretreated ULMs. These results warrant further prospective and randomized studies.

Response Evaluation Criteria

Purpose Treating solid tumors with cancer immunotherapy (CIT) can result in unconventional responses and overall survival (OS) benefits that are not adequately captured by Response Evaluation Criteria In Solid Tumors (RECIST) v1.1. We describe immune-modified RECIST (imRECIST) criteria, designed to better capture CIT responses. Patients and Methods Atezolizumab data from clinical trials in non–small-cell lung cancer, metastatic urothelial carcinoma, renal cell carcinoma, and melanoma were evaluated. Modifications to imRECIST versus RECIST v1.1 included allowance for best overall response after progressive disease (PD) and changes in PD definitions per new lesions (NLs) and nontarget lesions. imRECIST progression-free survival (PFS) did not count initial PD as an event if the subsequent scan showed disease control. OS was evaluated using conditional landmarks in patients whose PFS differed by imRECIST versus RECIST v1.1. Results The best overall response was 1% to 2% greater, the disease control rate was 8% to 13% greater, and the median PFS was 0.5 to 1.5 months longer per imRECIST versus RECIST v1.1. Extension of imRECIST PFS versus RECIST v1.1 PFS was associated with longer or similar OS. Patterns of progression analysis revealed that patients who developed NLs without target lesion (TL) progression had a similar or shorter OS compared with patients with RECIST v1.1 TL progression. Patients infrequently experienced a spike pattern (TLs increase, then decrease) but had longer OS than patients without TL reversion. Conclusion Evaluation of PFS and patterns of response and progression revealed that allowance for TL reversion from PD per imRECIST may better identify patients with OS benefit. Progression defined by the isolated appearance of NLs, however, is not associated with longer OS. These results may inform additional modifications to radiographic criteria (including imRECIST) to better reflect efficacy with CIT agents.

Response Evaluation Criteria

Objective: We examined the interobserver reliability of local progressive disease (L-PD) determination using two major radiological response evaluation criteria systems (Response evaluation Criteria in Solid Tumors (RECIST) and the European and American Osteosarcoma Study (EURAMOS)) in patients diagnosed with localized osteosarcoma (OS). Additionally, we describe the outcomes of patients determined to experience L-PD. Materials and Methods: Forty-seven patients diagnosed with localized OS between 2000 and 2012 at our institution were identified. Paired magnetic resonance imaging of the primary tumor from diagnosis and post-neoadjuvant chemotherapy were blindly assessed by two experienced radiologists and determined L-PD as per RECIST and EURAMOS radiological criteria. Interobserver reliability was measured using the kappa statistic (κ). The Kaplan Meier method and log-rank test was used to assess differences between groups. Results: Of 47 patients (median age at diagnosis 12.9 years), 16 (34%) had L-PD (by RECIST or EURAMOS radiological definition). There was less agreement between the radiologists using EURAMOS radiological criteria for L-PD (80.9%, κ = 0.48) than with RECIST criteria (97.9%, κ = 0.87). Patients with radiologically defined L-PD had a 5-year progression-free survival (PFS) of 55.6%, compared to a 5 year-PFS of 82.7% in the group of patients without L-PD (n = 31) (Log rank p = 0.0185). Conclusions: The interobserver reliability of L-PD determination is higher using RECIST than EURAMOS. RECIST can be considered for response assessment in OS clinical trials. The presence of L-PD was associated with worse outcomes.
