8537 Background: Carfilzomib (CFZ) is a proteasome inhibitor, active against hematologic malignancies. Preclinically, CFZ overcomes bortezomib (BTZ) resistance in multiple tumors, including myeloma (MM). PX-171–004 is an ongoing Phase II study evaluating safety and efficacy of CFZ in MM patients with relapsed disease after 1–3 prior therapies. Overall Response Rate (ORR) of 35.5% for all subjects was previously reported (ASH 2008); updated data are now available. Methods: Patients were divided into two cohorts: BTZ-naïve and BTZ-exposed. CFZ 20 mg/m2 was administered Days 1, 2, 8, 9, 15 and 16 in a 28-day cycle, for up to 12 cycles. Dexamethasone 4 mg po was administered prior to each dose in Cycle 1. The primary endpoint was ORR, defined as Partial Response (PR) or better. Secondary endpoints included Duration Of Response (DOR) and Time To Progression (TTP). Results: 31 patients were enrolled; 14 (45%) BTZ-naïve and 17 (55%) BTZ-exposed. Of the BTZ-exposed cohort, 2 subjects received BTZ exclusively as a single agent, 6 had BTZ in a chemotherapy combination, and 9 received BTZ in a transplant regime. Overall, 23 (74%) subjects had > 1 prior therapy and 27 (87%) received transplant. In BTZ-naïve patients, CFZ achieved an ORR of 57%; median DOR of 8.6 mos (range >1.9 to >9.7 mos). To date, 7 patients (50%) remain progression free and 3 patients have completed 12 cycles. The median follow-up was 10 mos and the median TTP has not been reached. For the BTZ- exposed group, CFZ achieved an ORR of 18%; median DOR not yet reached (>8.5 mos) (range >1 d to >8.5 mos). 7 patients (41%) are progression free and 3 patients have completed 12 cycles. Median follow-up and TTP were 9.2 and 8.9 mos, respectively. Conclusions: These preliminary results demonstrate that single-agent CFZ is tolerable for at least 1 yr and achieves sustained responses in relapsed MM. Prior BTZ mono/combination therapy does not preclude durable response with CFZ. These data support continuing evaluation of CFZ in the treatment of relapsed MM. [Table: see text] [Table: see text]

4519 Background: INDUCE-1 is a first-in-human trial evaluating fela, an IgG4 ICOS agonist non-T-cell depleting mAb, as monotherapy (mono) and in combo with P. ECs include tumor types, such as UC, with high ICOS expression and immunotherapy-favorable features. Fela induced IFNγ, increased PD-1/L1 expression, and enhanced antitumor activity in combo with PD-1 blockade nonclinically. We report preliminary efficacy, safety, and biomarker data of fela ± P in INDUCE-1 UC ECs. Methods: Eligible patients (pts) had recurrent/metastatic (R/M) UC of the upper or lower urinary tract, ≤6 prior systemic therapy lines in the advanced setting, measurable disease, and no active autoimmune disease. Pts received 0.3 or 1 mg/kg fela (mono EC; anti-PD-1/L1–experienced [exp] pts) or 0.3 mg/kg fela + 200 mg P (combo EC; anti-PD-1/L1–naïve pts) every 3 wks, up to 35 cycles until disease progression or unacceptable toxicity. Disease was assessed every 9 wks through wk 54, then every 12 wks. Archival and/or fresh biopsy tumor tissue was collected for biomarker analyses and safety assessed. Results: By Nov 6 2020, 13 anti-PD-1/L1–exp and 32 anti-PD-1/L1–naïve pts were evaluable in the mono and combo ECs, respectively. In the mono EC, median age was 69 yrs (range: 47–82), 92% of pts were male, and 85% received ≥2 prior therapy lines in the metastatic setting. In the combo EC, median age was 70 yrs (range: 42–84), 75% of pts were male, and 72% received ≥1 prior therapy line in the metastatic setting. In the mono EC, median duration of follow-up (mDoF) was 10.6 mo (range: 1.1–22.8); overall response rate (ORR) was 8% (1 partial response [PR]; 95% CI: 0.2, 36.0) with a duration of response (DoR) of 6.1 mo; disease control rate (DCR [response or stable disease for ≥9 wks]) was 23% (95% CI: 5.0, 53.8), and median overall survival (mOS) was 14.5 mo (95% CI: 2.8, NR), with 74% of pts alive at 6 mo. In the combo EC, mDoF was 9.6 mo (range: 0.9–28.3); ORR was 22% (7 PRs; 95% CI: 9.3, 40.0) with a median DoR of 8.3 months (range: 3.5–23.3+); DCR was 63% (95% CI: 43.7, 78.9), and mOS was 10.7 mo (95% CI: 5.2, 18.1), with 64% of pts alive at 6 mo. Grade ≥3 treatment-related AEs were reported for 0% and 9% of pts in the mono (N = 16) and combo (N = 44) safety populations, respectively. PD-L1 expression and ICOS-specific biomarkers are being evaluated, with promising trends observed in enrichment of clinical activity in preliminary analyses. Conclusions: Fela is the first ICOS agonist with reported single-agent activity in anti-PD-1/L1–exp relapsed/refractory UC. Fela + P in combo shows promising clinical activity and manageable safety in PD-1/L1–naïve R/M UC. Further study is warranted. Updated data to be presented.

Abstract Temsirolimus (CCI-779, Wyeth Pharmaceuticals) has been shown to inhibit proliferation of a variety of tumors and induce G1 cell cycle arrest by preventing activation of the serine/threonine kinase, mTOR (mammalian target of rapamycin), a downstream effector of the PI3K/Akt pathway. Several lines of evidence implicate the PI3K/Akt/mTOR pathway in hematological malignancies. Interim results of a phase II study evaluating the efficacy and toxicity of single-agent temsirolimus in patients with advanced malignancies are presented. Temsirolimus was administered weekly, at a flat dose of 25 mg, as a 30-minute intravenous infusion. Treatment was continued until evidence of disease progression or unacceptable toxicity. To date, 8 patients have been enrolled and 7 are evaluable for efficacy and toxicity (one patient did not receive temsirolimus). Of these 7 patients, 5 had AML, 1 CML-myeloid blast crisis, and 1 ALL. Median age was 68 years (range, 21 to 87 years) and 5 were male. All patients had received prior therapy, median 2 regimens (range, 1 to 3 regimens). The median number of temsirolimus doses administered was 3 (range, 1 to 10) with a median time on study of 18 days (range, 3 to 89+ days). The most common temsirolimus-related adverse events were grade ≤ 2 and consisted of anorexia, nausea and/or vomiting and diarrhea, mucositis, dermatitis, hypertriglyceridemia, hyperglycemia, hypomagnesemia, hypocalcemia, hypokalemia, hypophosphatemia, and fatigue/asthenia. No patient developed nonspecific pneumonitis. Grade 3 toxicities included fatigue/asthenia (2), hyperglycemia (1), painful mucositis with dehydration and electrolyte abnormalities (1), diarrhea with hypokalemia (1), and hypophosphatemia (1). No patient experienced grade 4 toxicities or death from temsirolimus. No patient required dose reductions, but 2 did have dose delays due to grade 3 mucositis (1) and out-of-state hospitalization for pneumonia and atrial fibrillation (1). No patient achieved a complete remission. One patient with heavily pre-treated Philadelphia-negative precursor B-cell ALL had a transient 79% to 91% reduction in peripheral blood blasts 4 days after the first dose of temsirolimus that was maintained for 12 days prior to disease progression with involvement of the synovial fluid in bilateral knees. At the time of analysis, 6 of the 7 patients have discontinued treatment due to disease progression (4), patient refusal (1), or physician decision (1). Preliminary findings indicate that temsirolimus is relatively well-tolerated at a dose of 25 mg per week and may have biologic activity in ALL. Accrual onto the study is currently ongoing.

Abstract Background: We previously reported substantial activity with single-agent bortezomib (VELCADE®; Vc) in patients (pts) with relapsed or refractory MCL in the PINNACLE study (JCO2006;24:4867–74), which resulted in approval of Vc for MCL pts following ≥1 prior therapy. All pts have now completed treatment. Here we report updated time-to-event data in all pts, and by response category, with extended follow-up. Methods: 155 pts (median age 65 yrs; 55%/41%/4% with 1/2/≥3 prior therapies; 77% Stage IV MCL; 55% positive bone marrow) received Vc 1.3 mg/m2 on days 1, 4, 8, and 11 of 21-day cycles; of these, 141 were response-evaluable. Response and progression were determined by modified International Workshop Response Criteria using independent radiology review. Results: After a median follow-up of 26.4 mo, 55 pts (35%) remained in follow-up; 93 (60%) had died, 2 (1%) had withdrawn consent, and 5 (3%) were lost to follow-up. Pts received a median of 4 treatment cycles (range 1–21; 8 in responding pts). Median time to first response was 1.3 months. Median duration of response (DOR) was 9.2 mo in all responders and has not been reached in pts achieving CR/CRu. Median time to progression (TTP), time to next therapy (TTNT; first Vc dose to start of next therapy), and overall survival (OS) are shown in the table for all pts and by response. Survival rate at 12-mo was 69% overall and 91% in responding pts. In pts refractory to their last therapy (no response or response with TTP <6 mo; n=58), median DOR was 5.9 mo, median TTP was 3.9 mo, median TTNT was 4.6 mo, and median survival was 17.3 mo. Safety profile was similar to previously reported; most common grade ≥3 AEs were peripheral neuropathy (13%), fatigue (12%), and thrombocytopenia (11%). The most common AE resulting in Vc discontinuation was peripheral neuropathy (10%). Twelve (8%) pts died on-study, including 5 (3%) considered related to Vc. Conclusions: Vc provides durable responses plus prolonged time off-therapy and survival in responding pts, suggesting substantial clinical benefit in relapsed/refractory MCL.

9055 Background: LungMAP is a National Clinical Trials Network umbrella trial for previously-treated SqNSCLC. S1400D is a phase II biomarker-driven therapeutic sub-study evaluating the FGFR inhibitor AZD4547 in patients (pts) with FGFR positive chemo-refractory SqNSCLC. Methods: Eligible pts had tumor FGFR alteration and/or mutation by next generation sequencing (Foundation Medicine), measurable disease, Zubrod PS 0-2, progression after 1 line of systemic therapy, and adequate end organ function. Receipt of prior immunotherapy was allowed. Eligible pts received AZD4547 80 mg bid orally. Primary endpoint was overall response rate (ORR) by RECIST; secondary endpoints included progression-free survival (PFS) and duration of response (DoR). Originally designed as a randomized trial of AZD4547 versus docetaxel, it was redesigned to be a single arm AZD4547 trial with the emergence of immunotherapy as standard 2ndline therapy. Forty pts were required to rule out an ORR of < = 15% if the true ORR was > 35% (90% power, alpha 0.05). Results: 93 pts (13% of pts screened on S1400) were assigned to S1400D; 43 were enrolled with 28 receiving AZD4547. Pt characteristics: median age 66.3 y (49-88), female (n = 8, 29%), & Caucasian (n = 25; 89%). Biomarker profile: FGFR1 amplification (n = 38; 86%); FGFR3 S249C (n = 4; 9%); FGFR3 amplification (n = 3; 7%); and FGFR3 fusion (n = 2; 5%). Nine pts (26%) had more than one biomarker alteration. The study was closed at interim analysis for futility in October 2016. Treatment related Grade 3 AEs were seen in 5 pts (dyspnea, fatigue, hyponatremia, lung infection & retinopathy); 1 pt had Grade 4 sepsis. There were no Grade 5 AEs. Median follow up among alive pts was 4.3 months (mos). Of 25 response evaluable pts, one with FGFR3 S249C had unconfirmed PR (4%, 95% CI 1-20%) with DoR of 1.5 mos. Median PFS was 2.7 mos (95% CI 1.4 - 4.3 mos). Conclusions: This is the first Phase II trial to evaluate AZD4547 as a targeted approach in pts with previously treated FGFR-altered SqNSCLC. AZD4547 had an acceptable safety profile but minimal activity in this biomarker-enriched cohort. Evaluation of other targeted agents in LUNG-MAP is currently ongoing. Clinical trial information: NCT02965378.

3071 Background: Mismatch repair deficient cancers harbor high levels of microsatellite instability and somatic mutations. Treatment with anti-PD-1 antibodies has resulted in durable objective responses in MSI-H cancer. As part of the ongoing, global, multicenter phase 2 studies KEYNOTE(KN)164 and KN158, we assessed the efficacy of pembrolizumab in patients (pts) with MSI-H tumors. Methods: Both studies enrolled pts with MSI-H status determined locally by IHC or PCR. KN164 enrolled pts with MSI-H CRC and ≥2 prior therapies, whereas the multicohortKN158 study included pts with MSI-H non-CRC and ≥1 prior therapy. Eligible pts in both studies received pembrolizumab 200 mg Q3W until progression, unacceptable toxicity, or pt/investigator decision. Tumor response was assessed every 9 wk by independent review per RECIST v1.1. Primary endpoint was ORR. Secondary endpoints included DOR, PFS, OS, and safety. Analyses were performed in pts from KN164 and KN158 who had ≥27 wk of follow-up as of Aug 3, 2016 and Oct 19, 2016, respectively. Results: KN164 enrolled 61 pts with MSI-H CRC (90% with ≥2 prior therapies) whereas KN158 included 21 pts with MSI-H non-CRC (42% with ≥2 prior therapies). In KN158 the most common tumor types were endometrial and small intestinal cancer (n = 4 each), cholangiocarcinoma (n = 3), and gastric and pancreatic cancer (n = 2 each). Median follow-up was 7.4 mo for MSI-H CRC and 4.5 mo for MSI-H non-CRC. ORR for MSI-H CRC was 26.2% (95% CI, 15.8%-39.1%), with 15 confirmed responses and 1 unconfirmed response, and ORR for MSI-H non-CRC was 42.9% (21.8%-66.0%), with 8 confirmed responses and 1 unconfirmed response. DCR was 50.8% (n = 31; 37.7%-63.9%) for MSI-H CRC and 66.7% (n = 14; 38.4%-83.7%) for MSI-H non-CRC. Median duration of response was not reached for either MSI-H CRC or non-CRC, and 100% of responses were ongoing. Survival and safety analyses are ongoing. Conclusions: Early results from KN164 and KN158 confirm the robust antitumor activity of pembrolizumab in heavily pretreated pts with MSI-H cancers. Clinical trial information: NCT02628067; NCT02460198.

9522 Background: UM is the most common primary intraocular malignant tumor in adults. Approximately 40-50% of patients (pts) with UM will ultimately develop metastatic disease. There is currently no standard approach for metastatic UM. Early studies of single agent immunotherapy (IO) in metastatic UM have yielded meager results. Combination checkpoint inhibitor IO has the potential to improve response rates and survival. Herein, we report the safety and efficacy of ipi/nivo in metastatic UM. Methods: We performed a single-arm phase II study in metastatic UM (CA184-187) for pts with at least 1 measureable lesion and ECOG PS 0-1. Any number of prior treatments were permitted. Pts received nivolumab 1mg/kg IV plus ipilimumab 3mg/kg IV every 3 weeks for a total of 4 doses; maintenance nivolumab was dosed 3mg/kg every 2 weeks or 480mg IV every 4 weeks. The primary efficacy endpoint was best overall response rate (BORR) as determined by irRC. Secondary endpoints were median progression free survival (PFS), median overall survival (OS), and one-year OS. Results: As of the January 31, 2019 data cutoff, 39 pts were enrolled. 35 pts received at least one treatment and were evaluable for toxicity. 5 pts were inevaluable for response due to lack of follow-up imaging, leaving 30 pts evaluable for efficacy. 32 pts (91%) experienced any adverse event (AE), and 29 pts (83%) experienced any treatment related AE (TRAE). Grade 3-4 TRAEs occurred in 14 pts (40%). 10 pts (29%) were removed from the study due to AEs. There were no treatment-related deaths. Median duration of follow up is 60.5 weeks. 19 pts (63%) completed all 4 cycles of ipi/nivo; median duration of treatment was 16 weeks. The BORR was partial response for 5 pts (17%), stable disease (SD) for 16 pts (53%), and progression of disease for 9 pts (30%). 8 pts had SD for at least 6 months. Median PFS was 26 weeks. Median OS was 83 weeks (1.6 years), and one-year OS was 62%. Conclusions: Full results of ipi/nivo safety and efficacy including immune-related AE and clinical characteristics of the responders will be presented at the meeting. Preliminary translational tumor work including RNA analysis has been performed on a subset of responders. Clinical trial information: NCT01585194.

1017 Background: T-DM1 is an ADC that combines the biological activity of trastuzumab (T) with targeted delivery of a potent antimicrotubule agent, DM1, to HER2-expressing cancer cells. In a phase I study, T-DM1 was administered IV q3w to pts with HER2+ MBC who had progressed on T + chemotherapy. T-DM1 was well-tolerated at the maximum tolerated dose (MTD) of 3.6 mg/kg, with no reports of cardiac toxicity. The confirmed objective response rate (ORR) for the 9 pts with measurable disease treated at the MTD was 44%. The phase II study described here further assesses tolerability and activity of T-DM1. Methods: This was a multi-institutional, open-label, single-arm phase II study, to enroll 100 pts. All eligible pts had progressed on HER2-directed therapy and had received chemotherapy in the metastatic setting. T-DM1 was administered at 3.6 mg/kg IV q3w. Primary objectives were assessment of ORR and of safety and tolerability. Results: As of the August 29, 2008, data-cut, 112 patients had enrolled, with baseline median age 54.5 (range 33–82); ECOG PS 2 or 3, 80%; 68.7% with > 3 sites of metastatic disease; median 3 (range 1–14) prior chemotherapy agents for metastatic disease, median 76.3 weeks prior T, and 55.4% with previous lapatinib. Due to limited F/U, the median number of T-DM1 cycles received was 5 (range 1–16), and 19 of the 107 efficacy evaluable patients had only one post-baseline tumor assessment. Fifty-six pts had discontinued study treatment. With a median follow-up of 4.4 mos, there were 42 (39.3%) ORs (CR or PR), 29 (27.1%) of which have been confirmed by follow-up (F/U) imaging. Among the subgroup of pts who had either >6 months F/U or had discontinued from the study at any time (n = 76) there were 33 ORs (43.4%), 29 (38.2%) of which were confirmed by F/U imaging. The most common grade 3–4 AE was thrombocytopenia (7.1%). Updated data will be presented at the meeting, including updated ORR, 6-month clinical benefit rate, ORR by independent review, progression-free survival, and duration of response. Conclusions: T-DM1 has single-agent activity in pts with previously treated, HER2+ MBC, and is well tolerated at the recommended phase II dose. [Table: see text]

7514 Background: The Fc-enhanced CD19 antibody MOR208 and the immunomodulatory drug LEN have demonstrated single agent activity in patients (pts) with R-R DLBCL. MOR208 and LEN have shown synergy in vitro and in vivo in preclinical lymphoma models. This ongoing phase II study assesses the safety and efficacy of MOR208 + LEN in pts with R-R DLBCL. Methods: Pts >18 years old with R-R DLBCL, ECOG 0–2, adequate organ function, having previously received ≥1 but not more than 3 prior therapies, including ≥1 CD20-targeting regimen and who are not candidates for autologous stem cell transplant (ASCT), are eligible. Treatment comprises up to 12, 28-day (d) cycles (C) of MOR208 12 mg/kg IV, weekly during C1–3 (loading dose d4 of C1); every second week C4–12 + LEN 25 mg po d1–21, C1–12. Pts progression-free after 12 cycles receive up to 12 additional cycles of MOR208 (every second week). The primary endpoint is the overall response rate (ORR) by central radiology assessment. Secondary endpoints include disease control, duration of response, progression-free and overall survival, safety, and response by cell of origin and other biomarkers. A preplanned safety evaluation was undertaken. Results: 31 of 80 planned pts were enrolled prior to data cutoff (3 January 2017). Median age was 74 years (range 47–82); 45% of pts received ≥2 prior lines of therapy; 23% had rituximab refractory disease; 74% had Ann Arbor stage ≥III disease; 65% had elevated lactate dehydrogenase level, and 52% had a poor revised International Prognostic Index (3-5). The most common treatment-emergent adverse events (any grade/grade ≥3 [% pts]) were neutropenia (39/26), anemia (23/0) thrombocytopenia (16/6), infections (26/10) diarrhea (13/0), pyrexia (13/0), and rashes (13/6). Of 26 response evaluable pts (median follow-up 3.3 months), ORR (investigator assessed) was 58% (15 pts), with 7 (27%) complete responses. Median time to response was 1.8 months. Conclusions: The combination of MOR208 + LEN is well tolerated and shows promising activity in pts with R-R DLBCL. Accrual and follow-up of pts is ongoing, as are cell of origin and other biomarker analyses. Clinical trial information: NCT02399085.

4532 Background: Pembro was approved for the treatment of locally advanced or metastatic UC that progressed during or after a platinum-containing regimen, based on the phase 3 KEYNOTE-045 (NCT02256436) trial that showed significantly improved OS with use of pembro. Updated results are presented from KEYNOTE-045 after >5 y of follow-up since the last patient (pt) was randomized. Methods: KEYNOTE-045 is a randomized, multisite, open-label, phase 3 trial. Pts with histologically or cytologically confirmed UC, progression after platinum-containing chemo, ECOG PS 0-2, measurable disease per RECIST v1.1, and ≤2 prior lines of systemic therapy were eligible. Pts were randomly assigned 1:1 to receive pembro 200 mg Q3W or investigator’s choice of paclitaxel 175 mg/m2 Q3W, docetaxel 75 mg/m2 Q3W, or vinflunine 320 mg/m2 Q3W. Primary end points are PFS (RECIST v1.1, blinded central review) and OS. ORR and duration of response (DOR) were key secondary end points. Results: As of Oct 1, 2020, among 542 enrolled pts, median time from randomization to data cutoff was 62.9 mo (range 58.6-70.9). 9.4% and 0% of pts in the pembro and chemo arms, respectively, completed 2 years of therapy. Median OS was longer for pembro vs chemo (10.1 vs 7.2 mo; HR, 0.71 [95% CI, 0.59-0.86]) overall and in pts with CPS ≥10 (8.0 vs 4.9 mo; HR, 0.59 [95% CI, 0.40-0.86]). For pts with CR or PR, median OS was not reached and 16.4 (95% CI, 11.3-25.1) mo in the pembro and chemo arms, respectively (Table). OS rates at 48 mo were 16.7% for pembro and 10.1% for chemo; 60-mo OS rates were 14.9% and 8.7%, respectively. OS benefit with pembro vs chemo continued regardless of age, ECOG PS, prior therapy, liver metastases, baseline hemoglobin, time from last chemo, histology, risk factors, and chemo choice. Median DOR for responders was longer for pembro vs chemo (29.7 mo [1.6+ to 60.5+] vs 4.4 mo [1.4+ to 63.1+]), and a greater proportion of responses lasted ≥48 mo (40.9% vs 28.3%, Kaplan-Meier) and ≥60 mo (32.8% vs 28.3%). ORR was higher for pembro vs chemo (21.9% vs 11.0%; difference 10.8% [95% CI, 4.6-17.0]). Fewer pts given pembro vs chemo experienced a treatment-related AE of any grade (62.0% vs 90.6%) or grade ≥3 (16.9% vs 50.2%). Conclusions: After 5 y, pembro maintained clinically meaningful OS benefit vs chemo in pts with locally advanced or metastatic UC that progressed during or after platinum-based chemo. Pts who responded to pembro experienced a durable response (median >2 y). Clinical trial information: NCT02256436 .[Table: see text]

4078 Background: To improve the poor prognosis of pts with MGC, we conducted a phase II study to evaluate the feasibility and efficacy of intensive NAC to enhance surgical respectability and survival. Methods: Eligible criteria included histologically proven metastatic or locally unserectable gastric adenocarcinoma and measurable or evaluable disease, PS 0–2 and sufficient organ functions. The primary endpoint was overall survival and the secondary endpoints were overall resonse rate (ORR) and toxicities. Since Oct. 2000, chemotherapy-naïve 120 pts with MGC have received S-1 (80 mg/m2 orally intake for 21 consecutive days) and CDDP (50 mg/m2 intravenous drip infusion on day 8) as NAC. Treatment was repeated every 5 weeks. The median administered courses were three (range: 1–7), and median follow up periods were 13.8 months. Results: The proportion of the duration as an outpatient- therapy was 86%. 77.5% of pts (93/120) went to surgical resection; 36 had distal gastrectomy and 57 had total gastrectomy. ORR was 62.5% (CR 1, PR 74), and 61.7%, 75.7%, 28.6% and 23.8% for primary lesion, metastatic lymph nodes, liver metastases and peritoneal metastasis, respectively. Toxicity (grade 3/4): neutropenia 7.5%, thrombocytopenia 6.7%, anemia 6.7%, anorexia 5.8%, nausea 2.5%; no treatment related death. Survival: median 23 months; 1 year 79%; 4 year 31% in all pts, and 42 months; 83%; 38% in pts with gastrectomy, respectively. In univariate analyses, overall survival (OS) was predicted by the responder, limited tumor location, H0, P0, but not by age, sex, histological type, gross type, T-factor, N-factor, or performance status. In multivariate analyses, H0, P0 and responder independently predicted OS. In pts with gastrectomy, H0, curative resection, PS0 and responder predicted OS. Conclusions: NAC with S-1 and CDDP was feasible and useful for pts with MGC and resulted in a promising survival rate. No significant financial relationships to disclose.
