e20721 Background: Pemetrexed maintenance therapy is associated with superior survival in stage IV nsqNSCLC patients. We have observed long term disease control in some patients treated with at least one cycle of Pem/Plat with potential for maintenance pem. There are no reports of data regarding long term PFS and OS in patients treated with Pem regimens. The objectives of our retrospective analysis are to determine the frequency of long term disease control on Pem maintenance and to identify parameters associated with longer PFS/OS. Methods: We included all patients with Stage IV nsqNSCLC who received at least one cycle of pem/plat between May 2010 and Nov 2013. We identified 240 patients from our database and analyzed their demographics, lab values, dates of therapy, and dates of progression. PFS/OS was estimated by the Kaplan-Meier method and associations with patient characteristics were assessed by log-rank tests and Cox proportional hazards analysis. The shortest potential follow up was 5 years. Results: Median age was 66 years, 60% were female, and 72% were Caucasian. Baseline ECOG performance status was 0(22%), 1(50%) and ≥ 2(22%). Median PFS was 6.2 months. At 1, 2, 3, 4, and 5 years of follow up absence of disease progression was seen in 33%, 14%, 7.5%, 4%, and 3%, respectively. Additionally, in terms of OS at 1-5 years, we observed 54.5%, 35%, 21%, 14%, and 11%. Lower baseline neutrophil: lymphocyte ratio (NLR) was strongly associated with improved PFS when using NLR≤5 vs > 5 (median PFS 13.2 mo vs 5.6 mo) Additionally, baseline Hemoglobin (mean = 12.03 g/dL, HR = .904, p = .0046) and Albumin (mean 3.3 g/dL, HR = .7722, p = .024) were associated with better PFS. Conclusions: The similarity in median PFS in our patients (6.2 mo) and clinical trial data suggests that our group of real world patients did not have uniquely favorable baseline characteristics. However, the patients most likely to reach long PFS/OS milestones had favorable baseline prognostic indicators suggesting that this patient subset might also be most likely to benefit from the recently approved regimen which combined Pembrolizumab with Pemetrexed/Carboplatin.

e21184 Background: Pembro monotherapy was approved in the US in October 2016 as 1L therapy for patients with metastatic NSCLC and PD-L1 tumor proportion score (TPS) ≥50% based on findings from KEYNOTE-024. With 5-year follow-up in KEYNOTE-024, median overall survival (OS) was 26.3 months (95% CI, 18.3–40.4) in the pembro arm. With 4-year follow-up in KEYNOTE-042, median OS was 20.0 months (15.9–24.2) in the pembro PD-L1 ≥50% subgroup. Our aim was to describe long-term, real-world outcomes with 1L pembro monotherapy for patients treated at US oncology practices with disease characteristics similar to those in the KEYNOTE trials. Methods: Patients initiating 1L pembro monotherapy from December 1, 2016, through November 30, 2017, were selected from the US nationwide Flatiron Health de-identified, electronic health record-derived database if they had stage IV or recurrent metastatic NSCLC with PD-L1 TPS ≥50%, ECOG performance status 0–1, and no known EGFR/ALK/ROS1 aberration (confirmed negative EGFR/ALK for nonsquamous tumors). Enhanced manual chart review was used to determine real-world progression (rwP), tumor response (rwTR), and reasons for pembro discontinuation. OS and real-world progression-free survival (rwPFS) were estimated using the Kaplan-Meier method. Data cutoff was August 31, 2020. Results: Median study follow-up was 38.4 months (range, 33.1–44.9). Of 228 eligible patients, median age was 71 years (range, 46–82); 123 (54%) were women; 156 (68%), 12 (5%), and 60 (26%) had nonsquamous, not otherwise specified, and squamous NSCLC, respectively; and 209 (92%) were current/former smokers. History of brain metastasis was recorded for 17 (7%). Pembro was discontinued by 151 patients (66%), most commonly because of disease progression (70; 46%) and secondarily for toxic effect of therapy (35; 23%); 87 patients (38%) received ≥1 additional lines of therapy. OS, rwPFS, and rwTR results are shown below. Conclusions: In this real-world study with 3-year follow-up, patients with PD-L1 TPS ≥50% metastatic NSCLC without known EGFR/ALK aberrations and good performance status treated with 1L pembro monotherapy experienced median OS of 23 months, similar to the OS observed in phase III pivotal clinical trials, supporting the long-term OS benefits of 1L pembro monotherapy in this patient population.[Table: see text]

9016 Background: 1L NIVO + IPI was shown to provide durable long-term overall survival (OS) benefit vs chemo regardless of tumor programmed death ligand 1 (PD-L1) expression in patients (pts) with advanced NSCLC in CheckMate 227 Part 1 (NCT02477826); 3-year OS rates were 33% vs 22% in pts with PD-L1 ≥ 1% (HR, 0.79 [95% CI, 0.67–0.93]) and 34% vs 15% in pts with PD-L1 < 1% (HR, 0.64 [95% CI, 0.51–0.81]). Here we report updated results from the study with 4 years’ minimum follow-up. Methods: Adults with previously untreated stage IV / recurrent NSCLC, no known EGFR/ ALK alterations , and ECOG performance status ≤ 1 were enrolled; pts were stratified by squamous (SQ) and non-squamous (NSQ) histology. Pts with PD-L1 ≥ 1% (n = 1189) were randomized 1:1:1 to receive NIVO (3 mg/kg Q2W) + IPI (1 mg/kg Q6W), NIVO alone (240 mg Q2W), or chemo. Pts with PD-L1 < 1% (n = 550) were randomized 1:1:1 to receive NIVO + IPI, NIVO (360 mg Q3W) + chemo, or chemo. OS with NIVO + IPI vs chemo in pts with PD-L1 ≥ 1% was the primary endpoint. Results: With minimum follow-up of 49.4 months (database lock, Feb 18, 2021), pts were at least 2 years beyond the protocol-specified end of immunotherapy treatment. Pts with PD-L1 ≥ 1% continued to show durable benefit with NIVO + IPI vs chemo (HR, 0.76 [95% CI, 0.65–0.90]); 4-year OS rates were 29% (NIVO + IPI), 21% (NIVO), and 18% (chemo). At 4 years, 14% (NIVO + IPI), 10% (NIVO), and 4% (chemo) remained progression free. Among responders, 34%, 30%, and 7% remained in response, respectively. In an exploratory analysis in pts with PD-L1 ≥ 50%, 4-year OS rates were 37% (NIVO + IPI), 26% (NIVO), and 20% (chemo). In pts with PD-L1 < 1%, OS HR for NIVO + IPI vs chemo was 0.64 (95% CI, 0.51–0.81); 4-year OS rates were 24% (NIVO + IPI), 13% (NIVO + chemo) and 10% (chemo). At 4 years, 12% (NIVO + IPI), 7% (NIVO + chemo), and 0% (chemo) remained progression free. Among responders, 31%, 13%, and 0% remained in response, respectively. Among pts who progressed on NIVO + IPI vs chemo, 7% vs 40% (PD-L1 ≥ 1%), and 9% vs 33% (PD-L1 < 1%), received subsequent immunotherapy. Benefit with NIVO + IPI vs chemo was observed for both SQ and NSQ histology (Table). With long-term follow-up, no new safety signals were identified. Conclusions: With 4 years’ minimum follow-up, 1L NIVO + IPI continued to provide durable, long-term OS benefit vs chemo in pts with advanced NSCLC regardless of PD-L1 expression or histology. Clinical trial information: NCT02477826. [Table: see text]

9000 Background: In the randomized phase 3 CheckMate 9LA trial (NCT03215706), first-line NIVO + IPI combined with 2 cycles of chemo significantly improved overall survival (OS), progression-free survival (PFS), and objective response rate (ORR) vs chemo alone (4 cycles). Clinical benefit was observed regardless of programmed death ligand 1 (PD-L1) expression level and histology. Here we report data with 2 years’ minimum follow-up from this study. Methods: Adult patients (pts) with stage IV / recurrent NSCLC, ECOG performance status ≤ 1, and no known sensitizing EGFR/ALK alterations were stratified by PD-L1 (< 1% vs ≥ 1%), sex, and histology (squamous vs non-squamous) and were randomized 1:1 to NIVO 360 mg Q3W + IPI 1 mg/kg Q6W + chemo (2 cycles; n = 361) or chemo alone (4 cycles; n = 358). Pts with non-squamous NSCLC in the chemo-alone arm could receive pemetrexed maintenance. The primary endpoint was OS. Secondary endpoints included PFS and ORR by blinded independent central review, and efficacy by different PD-L1 levels. Safety was exploratory. Results: At a minimum follow-up of 24.4 months for OS (database lock: Feb 18, 2021), pts treated with NIVO + IPI + chemo continued to derive OS benefit vs chemo, with a median OS of 15.8 months vs 11.0 months, respectively (HR, 0.72 [95% CI, 0.61–0.86]); 2-year OS rates were 38% vs 26%. Median PFS with NIVO + IPI + chemo vs chemo was 6.7 months vs 5.3 months (HR, 0.67 [95% CI, 0.56–0.79]); 8% and 37% of pts who had disease progression received subsequent immunotherapy, respectively. ORR was 38% with NIVO + IPI + chemo vs 25% with chemo. Similar clinical benefit with NIVO + IPI + chemo vs chemo was observed in all randomized pts and across the majority of subgroups, including by PD-L1 expression level (Table) or histology. Any grade and grade 3–4 treatment-related adverse events were reported in 92% and 48% of pts in the NIVO + IPI + chemo arm vs 88% and 38% in the chemo arm, respectively. Conclusion: With 2 years’ minimum follow-up, first-line NIVO + IPI + chemo demonstrated durable survival and benefit versus chemo in pts with advanced NSCLC; no new safety signals were identified. Clinical trial information: NCT03215706. [Table: see text]

PURPOSE Cancer is in the process of changing to become a chronic disease; therefore, an increasing number of oncologic patients (OPs) are being admitted to intensive care units (ICUs) for supportive care of disease or therapy-related complications. We compare the short- and long-term outcomes of critically ill mechanically ventilated OPs with those of their nononcologic counterparts. PATIENTS AND METHODS We performed a prospective study of patients admitted to our ICU between October 2017 and February 2019. Demographic, physiologic, laboratory, clinical, and treatment data were obtained. The primary outcome was survival at 28 days and at the end of the follow-up period. Secondary outcomes were survival according to acute severity scoring (Acute Physiology and Chronic Health Evaluation II score), Eastern Cooperative Oncology Group (ECOG) performance status, and Charlson comorbidity index. RESULTS A total of 1,490 patients were admitted during the study period; 358 patients (24%) were OPs, and 100 of these OPs were supported with mechanical ventilation. Seventy-three percent of OPs had an ECOG performances status of 0 or 1, and 90% had solid tumors. Reason for admission to the ICU was postoperative admission in 44 patients and neutropenic infection in 10 patients. The follow-up period was 148 days (range, 42 to 363 days). Survival at 28 days was similar between OPs and nononcologic patients and associated with the Acute Physiology and Chronic Health Evaluation II score. However, long-term survival was lower in OPs compared with nononcologic patients (52% v 76%, respectively; P < .001) and associated with poor ECOG performance status. CONCLUSION Short-term survival of critically ill, mechanically ventilated OPs is similar to that of their nononcologic counterparts and is determined by the severity of the critical illness.

7127 Background: Abraxane (A) is a cremophor free, albumin-bound nanoparticle of paclitaxel (P) approved for the treatment of metastatic breast cancer. Belani et al. (JCO 21: 2933–2939, 2003) reported that P 100 mg/m2 days 1, 8 and 15 q 28 days with C AUC 6 on day 1 led to a 32% response rate in 132 patients (pts) with NSCLC. The median time to progression (TTP) was 35 weeks (wks) for stage IIIB and 29 wks for stage IV. Methods: This study was designed to determine if substituting A for P at an identical dose would lead to an improved response rate, TTP or decreased toxicity. Results: Fifty-six pts with stage IIIB/IV NSCLC previously untreated with chemotherapy were enrolled. The median age was 66 (range 37 - 83); 37 were male and median ECOG performance status was 1 (range 0–2). Thirteen pts were stage IIIB. Metastases included bone (17), liver (7), brain (2) and lymph nodes (16). Currently a total of 239 cycles of therapy have been administered with a median of 4 (range 1–8) cycles per pt. In 194 (81%) full dose A was administered on days 1, 8 and 15. The table below shows toxicities compared to P: Seven pts (13%) experienced grade (G) 1 neuropathy and 3 pts (5%) experienced G 2 neuropathy. Five pts were inevaluable for response due to removal from study after <2 cycles of treatment (2 died from progressive disease, 2 because of toxicity - thrombocytopenia and neutropenia - and 1 refused). Of 51 evaluable pts 1 (2%) had a complete response and 23 patients (45%) achieved a partial response. Four of 10 evaluable stage IIIB pts obtained a PR. Twenty-one pts were stable for at least 12 weeks of whom twenty remain stable at 12–29 weeks and one progressed at 23 weeks. A total of 13 pts have progressed and 3 pts have died. The Kaplan-Meier estimate of median TTP is 23 wks and maximum follow up is 34 wks. Conclusions: We conclude that combining A and C is tolerable and active in the treatment of newly-diagnosed NSCLC and antitumor activity compares favorably to that of P/C. Further studies are warranted in this population. [Table: see text] [Table: see text]

7565 Background: Standard first-line chemotherapy for elderly NSCLC pts has been considered as a monotherapy with vinorelbine or gemcitabine globally. However, we have demonstrated the high efficacy of CP for elderly pts in our previous trial (Ann Oncol 2010). Meanwhile, D has been considered as an alternative option for this population in Japan according to the result of WJTOG9904 (JCO 2006). Thus we compared the two regimens to select the proper candidate for future phase III trial. Methods: Eligible pts were aged 70 years or older with newly diagnosed stage IIIB/IV NSCLC; ECOG performance status 0-1; adequate organ function; written informed consent. Pts were randomized to receive carboplatin (AUC 6) on day 1 and paclitaxel (70mg/m2 on day 1, 8, and 15) every 4 weeks or D (60mg/m2 on day 1) every 3 weeks. The primary endpoint was overall response rate (ORR), and secondary endpoints were progression-free survival (PFS), overall survival, and toxicity profile. Assuming that ORR of 40% would be potential usefulness while ORR of 20% would be the lower limit of interest, 40 pts in each arm were required if expect 10% loss to follow up. Results: Between July 2006 and September 2010, 84 pts were enrolled and 41 pts in CP arm and 42 pts in D arm were eligible (median age, 76 years; 75% male; 72% stage IV). Median treatment cycle was 4 in each arm (CP, range 1-6; D, range 1-8). ORRs were 51% (95%CI: 36-66%) and 26% (95%CI: 12-39%) in the CP and D arm, respectively. With a median follow-up of 18.4 months, median PFS were 6.5 and 3.9 months in the CP and D arm, respectively (Logrank, P=0.0027). Grade 3 or severer toxicities were as follows: neutropenia (CP, 56% and D, 79%), anemia (CP, 15% and D, 7%), thrombocytopenia (CP, 10% and D, 0%), infection (CP, 20% and D, 25%). One treatment-related death due to neutropenia, pneumonia, and lethal arrhythmia occurred in D arm but none in CP arm. Conclusions: The platinum doublet CP achieved higher activity with an acceptable toxicity profile for elderly pts with advanced NSCLC compared to monotherapy with D. The superiority of CP to the monotherapy in this trial is consistent with results of recent IFCT-0501 trial (Lancet 2011).

26 Background: GEP and PD-L1 expression have been associated with anti–PD-1/PD-L1 therapy. In this retrospective observational study we explored the prognostic value of GEP and PD-L1 expression in pts with EC receiving standard-of-care therapy (SOC). Methods: Tumor tissue samples collected from 2005 to 2017 were procured from Yonsei Cancer Center (South Korea), Memorial Sloan Kettering Cancer Center (USA) and Aarhus University Hospital (Denmark). GEP score was derived from an 18-gene signature using extracted tumor RNA analyzed by NanoString nCounter; GEP high/intermediate (GEP-H/I) and low were defined by a cutoff of –1.540, consistent with pembrolizumab clinical trials. PD-L1 expression was assessed by PD-L1 IHC 22C3 pharmDx assay (Agilent); positive was defined as combined positive score (CPS) ≥ 10, where CPS is the the number of PD-L1–positive cells (tumor cells, lymphocytes and macrophages) divided by the total number of viable tumor cells, multiplied by 100. Associations of GEP score and PD-L1 expression with clinicopathologic variables were analyzed by chi-square test and multiple logistic regression models. Overall survival (OS) from diagnosis date to death date/last follow-up was analyzed using Cox proportional hazards models adjusting for age, sex, stage, region and ECOG performance status (PS). Results: 294 samples with both PD-L1 and GEP data were analyzed. Median age was 65 y (range 33-88); 85% were from men, 58% were stage IV, 63% were esophageal adenocarcinoma (EAC) and 37% were esophageal squamous cell carcinoma (ESCC). Overall 36% of tumors were GEP-H/I: 46% in EAC vs 18% in ESCC. GEP was not associated with OS overall (adjusted hazard ratio [aHR] –0.90; 95% CI 0.68-1.18) or in pts with EAC (aHR 0.93; 95% CI 0.68-1.27) or ESCC (aHR 0.76; 95% CI 0.40-1.44). 21% of tumors were PD-L1-CPS ≥ 10: 18% in EAC and 26% in ESCC. PD-L1 expression was associated with ECOG PS (adjusted odds ratio 0.520; 95% CI 0.309-0.875; P = 0.014) but was not associated with OS overall (aHR 0.89; 95% CI 0.64-1.24) or in pts with EAC (aHR 0.97; 95% CI 0.63-1.49) or ESCC (aHR 1.31; 95% CI 0.73-2.34). Conclusions: Our results suggest that T-cell–inflamed GEP and PD-L1 expression may not be prognostic in pts with EC who received SOC.

457 Background: Benefit of IO (PD1 and PD-L1 inhibitors) for mUC was observed in clinical trials but real-world evidence for benefit and clinical outcomes is limited. Methods: This was a retrospective study of adult pts with mUC who initiated IO regardless of PD-L1 expression in the first- (1L cohort) or second-line (2L cohort) setting between 5/1/2016-1/31/2019 in the US Oncology Network (USON), a network of community oncology practices. Descriptive and Kaplan-Meier analyses to evaluate baseline characteristics, treatment patterns and clinical outcomes were conducted using data from USON’s electronic heath record. Results: Among 393 pts in the 1L cohort, median (range) age at IO initiation was 77 (42, 90+), 74% were male, 69% were White, and 19.1% and 4.1% had ECOG performance status (PS) 2 and 3/4, respectively. Among the 366 pts in the 2L cohort, median (range) age at IO initiation was 70 (29, 90+), 74% were male, 71% were White, and 19.7% and 1.4% had ECOG PS 2 and 3, respectively. Median (range) follow-up durations from IO initiation were 4.2 (0, 34.1; 1L cohort) and 4.1 (0, 31.3; 2L cohort) months (mo), during which time 43.1% (1L cohort) and 44.4% (2L cohort) of pts died. Median overall survival (OS) from IO initiation (95% confidence interval [CI]) was 10.6 (9.7, 13.2) mo for the 1L cohort and 9.4 (7.1, 11.5) mo for the 2L cohort; 1-year survival probabilities (95% CI) were 46.6% (40.1%, 52.8%; 1L cohort) and 43.4% (36.8%, 49.8%; 2L cohort). By the end of the follow-up, 48.1% of 1L pts and 47.8% of 2L pts were alive and did not advance to next line of therapy, and 13.5% of 1L and 13.4% of 2L cohort pts advanced to the next line of therapy. Median (95% CI) treatment durations were 2.6 (2.1, 2.9) and 2.8 (2.2, 3.5) mo for the 1L and 2L cohorts, respectively; 6-mo ongoing treatment probabilities (95% CI) were 26.6% (22.2%, 31.2%; 1L cohort) and 31.4% (26.4%, 36.4%; 2L cohort). Conclusions: OS of pts in the real world receiving 1L and 2L IO appears consistent with clinical trial results, although survival follow-up is limited. A minority of pts received post-IO therapy. Future research should examine influence of pt characteristics and PD-L1 expression on treatment choice and outcomes.

e15743 Background: NG is a standard 1st line treatment for APC. Although recommended in 2nd line after FOLFIRINOX, there is little evidence of its efficacy, tolerability and of markers of efficacy. Methods: We performed a multicenter retrospective cohort study, including patients (pts) with APC from 5 centers in Portugal treated with 2nd line NG after 1st line FOLFIRINOX from 01/2013-12/2016. We collected demographic, clinicopathological characteristics and treatment data. We used descriptive statistics, Kaplan-Meier methods and Cox proportional hazards analysis. Results: 30 pts were included; median age was 64 years (range 45–78); the majority had stage IV (90%) disease, an ECOG Performance Status of 0 (76.7%) and had received a median of 8.5 cycles of FOLFIRINOX (range 1–18). A median of 6 cycles of NG were administered (range 1–13). Median progression free survival (PFS) and overall survival (OS) were 6.4 months (CI 95% 3.0-8.5) and 11.4 months (CI 95% 8.4–16.5), respectively, and did not differ by age < 65 or ≥65 (p = 0.87; p = 0.57 respectively). The most frequent toxicity was fatigue (66.6%, any grade). Grade 3-4 events occurred in 40% of pts – thrombocytopenia in 16.7%, neutropenia in 10.0%; anemia, sensorial neuropathy, fatigue and diarrhea each occurred in 3.3% of patients. No febrile neutropenia events or toxic deaths occurred. Median CA 19.9 at the beginning of NG was 1254U/mL (IQR: 207–6775); the median decrease of CA19.9 at 3 months was 45U/mL (IQR:-1373– +174). CA 19.9 variation at 3 months did not correlate with PFS (p = 0.53) or OS (p = 0.09) in multivariate analysis (adjusted for age and stage at diagnosis). Neutrophil to Lymphocyte ratio (NLR) was high ( > 3.0) in 37.5% of patients before 1st line treatment and in 27.6% at the beginning of NG. In multivariate analysis NLR before 1st or 2nd chemotherapy lines were not associated with PFS (p = 0.39; p = 0.14 respectively) or OS (p = 0.44; p = 0.12, respectively). Conclusions: In this cohort of pts with APC, NG was an effective and well tolerated 2nd line regimen after FOLFIRINOX failure, even in pts ≥65 years. Neither CA19.9 variation at 3 months nor NLR were markers of NG clinical benefit.

Abstract This study was coordinated by the ECOG-ACRIN Cancer Research Group (Robert L. Comis, MD and Mitchell D. Schnall, MD, PhD, Group Co-Chairs) and supported in part by Public Health Service Grants CA180794, CA180820, CA180795, CA180791, CA189859, CA180790, CA180853, and from the National Cancer Institute, National Institutes of Health and the Department of Health and Human Services.

Background: Relapse after achieving a complete remission (CR) in AML portends for a poor prognosis and allogeneic transplant after achieving a second remission is the only chance for cure. Patients who undergo a transplant have a 30-40% chance of long term survival. This is a follow-up of a report published 10 years ago (Rowe JM, ASH 2005, abstract 546) and includes contemporary studies and longer follow-up. The study examines the long term overall survival (OS) of AML patients who relapsed after achieving first CR in 9 successive ECOG-ACRIN trials for newly-diagnosed AML patients (E3483, E3489, PC486, E3993, E4995, E1490, E3997, E1900 and E3999) from March 1984 to November 2008. Methods: OS was defined as time from first relapse to death from any cause. Kaplan-Meier estimates were used to estimate the event-time distributions for OS. Multivariate model stratified on protocol and treatment were used to examine whether the following factors are prognostic for OS from relapse: age, gender, cytogenetic risk, ECOG performance status, WBC, platelets, hemoglobin, marrow blasts, peripheral blasts, and duration of CR. All P values were based on 2-sided tests. Results: A total of 3160 patients were enrolled in the 9 studies. The median follow-up on patients still alive was 10.0 years. Among those 3160 patients enrolled, 1864 (58.9%) achieved first CR of which 1086 (58.2%) had documented relapse. The median age at diagnosis of the relapsed patients was 50 (range: 16-84) and 50.6% were males. Fifty percent of the patients had reliable cytogenetic results. Of those, 13.5% had favorable cytogenetics, 55.8% - intermediate and 30.6% had unfavorable baseline results. The median OS from relapse was 0.5 years. The 2- and 5-year OS were 16(±1)% and 10(±1)%, respectively. This is true in even the most contemporary studies (E1900 and E3999) with median OS of 0.6 and 0.4 years, respectively. By age stratification (< or ≥ 55), 5-year OS was 13(±1)% and 5(±1)%, respectively (figure 1). Among patients<55, those with unfavorable cytogenetics had the poorest prognosis (median OS of 0.4 years and 5-year OS of 6(±3)%. Those with favorable and intermediate cytogenetics had similar OS with 0.7 and 0.6 years median OS and 5-year OS of 16(±5)% and 17(±3)%, respectively (figure 2). Multivariate analysis was perfomed on 517 patients who had enough baseline information, including cytogenetics. Factors that were significantly associated with OS from relapse included: age (p<0.001), ECOG performance status (p=0.04), hemoglobin (p=0.03), cytogenetics (p=0.045) at baseline and duration of CR (p<0.001). Conclusions: The short- and long-term OS of AML patients post-relapse is dismal (<10%). Although age<55 and favorable cytogenetics at diagnosis are relatively good prognostic factors, the general survival of even these patients is very poor. Disappointingly, these data are also applicable to the most contemporary studies. Long-term survival was possible only in the minority of patients who survived the relapse, achieved a second CR and then successfully underwent an allogeneic transplant. These data are crucial when considering post-remission strategy, and suggest that offering a therapy most likely to lead to cure in CR1 is the preferred option. Figure 1.
