Abstract We performed a retrospective analysis from our transplant registry on first allogeneic hematopoietic stem cell transplantations (HSCT) for acute myeloid leukemia (AML) patients (pts) between 1996 and 2007. Our principal objective was to analyze the impact of molecular markers on the long-term overall and disease-free survival (OS and DFS) after first allogeneic HSCT. We found 364 pts, only 63 pts had retrospectively available conserved cells at diagnosis. The expression levels of WT1, Evi1, Flt3 and Hoxa9 were performed by quantitative RT-RQPCR. The mutational status of MLL duplication, FLT3 (internal tandem duplication or nucleotide substitutions) (ITD), NPM1 and CEBPα were determined by PCR, RFLP and/or sequencing analysis. All pts except 1 had a karyotype analysis at diagnosis. Among these 63 pts, there were 27 (43%) males and 36 (57%) females, with a median age of 41 years (18-64). The FAB classification was M0: 6, M1: 10, M2: 13, M4: 6, M5: 21, M6: 3, M7: 1 and 3 unclassified. Concerning the karyotype analysis, 25 (40%) pts had a normal karyotype, 37 (60%) pts presented cytogenetic abnormalities classified as favourable prognosis in 5 cases (8%), intermediate in 13 cases (21%) and poor in 19 cases (31%). Regarding the molecular markers evaluated in all pts: 4(6%) pts had Flt3over-expressed (ov-ex), 19 (30%) FLT3 ITD+, 3 (5%) MLLdup, 10 (16%) Hoxa9 ov-ex, 7 (11%) Evi1 ov-ex, 15 (24%) NPM1mut+, 25 (40%) WT1 ov-ex and 1 CEBPαmut+ (this marker was evaluated only in 12 pts). Associations between these markers and the karyotype prognosis groups are shown in Figure1. Twenty three (36%) pts had no abnormal molecular markers and 40 (54%) pts had at least one abnormal marker: 10 (16%) 1 marker, 10 (16%) 2 markers, 12 (19%) 3 markers, 4 (6%) 4 markers and 4 (6%) 5 markers. Concerning the karyotype, among the 23 negative molecular pts, 22 have been evaluated and there were 9 (41%) normal, 11 (50%) poor and 2 (9%) favourable; and among the 40 positive pts, 16 (40%) were normal, 8 (20%) poor, 13 (32.5%) intermediate and 3 (7.5%) favourable. Concerning transplantation, 50% of HSCT were done after 2004 and the median interval between diagnosis and transplantation was 6 months (2.6–68.5). Before conditioning, 41 pts were in CR (26 CR1, 14 CR2 and 1 CR3), 8 in PR and 14 in relapse. Twenty five (40%) pts received a non-myelo-ablative conditioning and 38 (60%) a myelo-ablative one. There were 34 sex-mismatched (21 M→F and 13 F→M), 21 ABO incompatibility (6 minor and 15 major), 55 were HLA matched and 8 mismatched. Twenty three (36.5%) pts received PBSC, 37 (59%) bone marrow and 4 (6.5%) cord blood cells from 47 (75%) HLA siblings and 16 (25%) unrelated donors. After transplantation, 59 (94%) pts engrafted, 42 developed AGVHD (21gr1, 13 gr2 and 8 gr4), and among 51 evaluable pts, 13 developed cGVHD (7 limited and 6 extensive). At the last follow-up, 20 pts have relapsed, 29 pts are alive (28 CR and 1PR) and 34 died [18 (53%) from TRM and 16 (47%) from relapse]. At the median follow-up of 48 months, the OS and DFS for the whole population were 40% (33–47) and 40% (34–46) respectively with a maximum follow-up of 130 months and for the different subgroups according to karyotype and molecular markers the results are shown in Table 1. The univariate analysis showed a significant impact of FLT3 ITD and over-expression of FLT3RQ on long-term DFS, (p=0.03 and p=0.02 respectively), and a trend on long-term OS (p=0.08). Concerning the karyotype and some other markers (MLL, EVI1, NPM1 and Hoxa9), we did not observe any significant difference because of small number of pts in some subgroups. The known benefic impact of NPM1mut+, was erased because the majority of this group presented an associated FLT3 ITD+. In addition, we are performing a multivariate analysis that will be presented. In conclusion, allogeneic HSCT in this high risk population of AML pts, allowed a good probability of long-term OS and DFS, despite the presence of high number of bad molecular markers and cytogenetic abnormalities. Finally, AML pts with FLT3 ITD+ seem not benefit from allogeneic HSCT as well as patients with NPM1mut+ associated with FLT3ITD+. Figure 1.

Abstract Introduction. Autologous Bone Marrow Transplantation (Auto-BMT) is currently rarely used in the treatment of Acute Myeloid Leukemia (AML). However, it may represent a good therapeutic option in a specific subset of patients, mainly in consolidation of both low risk (LR) and MRD negative AML without an available HLA matched donor. Aims. To review our database of AML patients who received Auto-BMT from 2005 to 2014 and who were referred to Bologna Institution, in order to assess the efficacy of the procedure in terms of Overall Survival (OS) and Disease Free Survival (DFS). Patients and methods: From 2005 to 2014, 98 AML patients underwent Auto-BMT in several Italian Institutions. 89/98 patients are evaluable for survival and outcome data. The 89 patients considered (42 female, 47 male), had a median age of 49 years (range 15-70). Cytogenetics was performed in all patients by conventional karyotype (22 patients were also analyzed by Single Nucleotide Polymorphisms Array); molecular analysis (FLT3 TKD and ITD, and NPM1 mutational analysis) was available for 51/89 patients. Molecular monitoring by specific fusion transcripts (CBF-MYH11 and AML1-ETO) was performed in CBF positive leukemias (inv(16) and t(8;21)) at the time of diagnosis, after induction, consolidation courses, and every 3 months in the first 2 years of follow-up. Based on this data, and according to ELN guidelines, a risk stratification identified 41 patients with a LR AML (t(8:21), inv(16) or NPM1+/FLT3- with normal karyotype), 4 patients with a high risk (HR) AML (complex karyotype or FLT3 ITD mutated or inv(3) or t(6;9)) and 44 patients with a standard risk (SR) AML (normal karyotype, other alterations). Results. All the patients received an induction chemotherapy treatment, as follows: a "3+7-like" course in 48 cases, a Fludarabine-based regimen in 20 patients and a Gemtuzumab-ozogamicin (GO)-based regimen in 21. 83/89 (93.3%) patients received a median of 2 consolidation courses of chemotherapy (range 1-4) before proceeding to Auto-BMT, performed in 1st CR. 6/89 (6.7%) patients received Auto-BMT in first relapse. 41 patients relapsed after auto-BMT and were treated with a re-induction chemotherapy, or were enrolled in clinical trials. 24 patients reached a 2nd complete remission, and 12 patients underwent an allogeneic BMT in 2nd CR. With a median follow up of 6 years, the median Overall Survival (OS) of the entire population was 64.3 months (range 5.8-294.2 months); the 1 year OS and the 5 years OS were, 97.1%, and 67.9%, respectively. The median Disease Free Survival (DFS) of the 83 patients treated with Auto-BMT in 1st CR was 36 months (range 1.3-293 months). The 1-year DFS and the 5-years DFS were 85% and 56.7%, respectively. Transplant related mortality (TRM, death in 100 days after BMT) was 1.2% for auto-BMT and 6.5% for allogeneic BMT. First, to assess the role of the number of consolidation courses we compared patients who received none or 1 consolidation course with patients who received 2 or more cycles, who showed a better OS (p= 0.0061, Figure 1). There was no statistical difference in terms of OS between young and elderly patients (cut off=65 years). Second, we compared patients who achieved a negative minimal residual disease status before auto-BMT (n=37) with patients who did not (n=9). MRD negativity offered a significantly better outcome in terms of 5-years OS (83.4% and 50% respectively); the median OS of MRD neg was not yet reached; the median OS of MRD pos was 27 months (p= 0.0130) (Figure 2). Conclusions: Auto-BMT offers a chance to achieve long-term DFS and OS if used as a consolidation therapy both in patients with LR and SR AML. The major role could be played in MRD negative patients, offering the best chances to achieve a long-term OS. Auto-BMT can be also a good choice as consolidation therapy for elderly patients, in which allo-BMT could induce high morbidity and mortality rates. The small patients cohort and the retrospective analysis don't allow us to define the best induction therapy to be used before auto-BMT. However, based on our findings we suggest a therapy schedule including two or more consolidation courses in patients who obtain a first CR, and to proceed then to auto-BMT.

Purpose Luminal breast cancer has a long natural history, with recurrences continuing beyond 10 years after diagnosis. We analyzed long-term follow-up (LTFU) of efficacy outcomes and adverse events in the Breast International Group (BIG) 1-98 study reported after a median follow-up of 12.6 years. Patients and Methods BIG 1-98 is a four-arm, phase III, double-blind, randomized trial comparing adjuvant letrozole versus tamoxifen (either treatment received for 5 years) and their sequences (2 years of one treatment plus 3 years of the other) for postmenopausal women with endocrine-responsive early breast cancer. When pharmaceutical company sponsorship ended at 8.4 years of median follow-up, academic partners initiated an observational, LTFU extension collecting annual data on survival, disease status, and adverse events. Information from Denmark was from the Danish Breast Cancer Cooperative Group Registry. Intention-to-treat analyses are reported. Results Of 8,010 enrolled patients, 4,433 were alive and not withdrawn at an LTFU participating center, and 3,833 (86%) had at least one LTFU report. For the monotherapy comparison of letrozole versus tamoxifen, we found a 9% relative reduction in the hazard of a disease-free survival event with letrozole (hazard ratio [HR], 0.91; 95% CI, 0.81 to 1.01). HRs for other efficacy end points were similar to those for disease-free survival. Efficacy of letrozole versus tamoxifen for contralateral breast cancer varied significantly over time (0- to 5-, 5- to 10-, and > 10-year HRs, 0.62, 0.47, and 1.35, respectively; treatment-by-time interaction P = .005), perhaps reflecting a longer carryover effect of tamoxifen. Reporting of specific long-term adverse events seemed more effective with national registry than with case-record reporting of clinical follow-up. Conclusion Efficacy end points continued to show trends favoring letrozole. Letrozole reduced contralateral breast cancer frequency in the first 10 years, but this reversed beyond 10 years. This study illustrates the value of extended follow-up in trials of luminal breast cancer.

Purpose The toxicity of allogeneic stem-cell transplantation can be substantially reduced using a reduced-intensity conditioning (RIC) regimen. This has increased the proportion of patients with myeloid malignancies eligible for allogeneic transplantation. However, the capacity of RIC allografts to produce durable remissions in patients with acute myeloid leukemia (AML) and myelodysplasia (MDS) has not yet been defined, and consequently, the role of RIC allografts in the management of these diseases remains conjectural. Patients and Methods Seventy-six patients with high-risk AML or MDS received an allograft using a fludarabine/melphalan RIC regimen incorporating alemtuzumab. The median age of the cohort was 52 years (range, 18 to 71 years). Results The 100-day transplantation-related mortality rate was 9%, and no patient developed greater than grade 2 graft-versus-host disease. With a median follow-up of 36 months (range, 13 to 70 months), 27 patients were alive and in remission, with 3-year actuarial overall survival (OS) and disease-free survival (DFS) rates of 41% and 37%, respectively. The 3-year OS and DFS rates of patients with AML in complete remission at the time of transplantation were 48% and 42%, respectively. Disease relapse was the most common cause of treatment failure and occurred at a median time of 6 months after transplantation. All but one patient destined to relapse did so within 24 months of transplantation. Conclusion The extended follow-up in this series identifies a high risk of early disease relapse but provides evidence that RIC allografts can produce sustained DFS in a significant number of patients with AML who would be ineligible for allogeneic transplantation with myeloablative conditioning.

PURPOSE: We conducted a phase II pilot study of dose-intensive adjuvant chemotherapy with doxorubicin followed sequentially by high-dose cyclophosphamide to determine the safety and feasibility of this dose-dense treatment and to estimate the disease-free and overall survival in breast cancer patients with four or more involved axillary lymph nodes. PATIENTS AND METHODS: Seventy-three patients received adjuvant treatment with four cycles of doxorubicin 75 mg/m2 as an intravenous bolus every 21 days, followed by three cycles of cyclophosphamide 3,000 mg/m2 every 14 days with granulocyte colony-stimulating factor support. RESULTS: Seventy-one patients were assessable, and all but two completed all planned chemotherapy. There was no treatment-related mortality. The most common toxicity was neutropenic fever, which occurred in 39% of patients. Median disease-free survival is 66 months (95% confidence interval, 34 to 98 months), and median overall survival has not yet been reached. At 5 years of follow-up, the disease-free survival is 51.7%, and overall survival is 60.0%. There is no long-term treatment-related toxicity, and no cases of acute myelogenous leukemia or myelodysplastic syndrome have been observed. CONCLUSION: Our pilot study of doxorubicin followed by cyclophosphamide demonstrates the safety and feasibility of the sequential dose-dense plan. Long-term follow-up, although noncomparative, is promising. However, this regimen is associated with a higher incidence of toxicity (and also higher costs) than the standard dose and schedule of doxorubicin and cyclophosphamide, and therefore it should not be used as conventional therapy in the absence of demonstrated improvement of outcome. Randomized trials testing the dose-dense approach have been completed but not yet reported. Because the sequential plan can decrease overlapping toxicities, it is an appropriate platform for the addition of newer active agents, such as taxanes or monoclonal antibodies.

Abstract Introduction: FL is generally responsive to conventional-dose chemotherapy but long term disease-free survival (DFS) is uncommon. High-dose chemo-radiotherapy followed by ASCT has the potential to induce remission in this disease but the long-term benefit of this modality remains to be determined. Methods: Between 1990 and 2003, we transplanted 52 pts originally diagnosed with low-grade FL (31 grade 1, 21 grade 2). Twenty-five (48%) had biopsy-proven large cell transformation (FL grade 3 or diffuse large cell lymphoma) before ASCT. The median number of prior therapies was 2 (range: 1 to 7). Prior to ASCT, 45 pts (87%) were responsive to salvage therapy with 20 pts (38%) in CR. Five pts (10%) had chemo-resistant disease at the time of ASCT. High-dose regimens included BCNU-cyclophosphamide-etoposide (31%), melphalan/TBI (27%), and cyclophosphamide/TBI (25%). Thirty-eight pts (73%) received peripheral stem cells (PSCT) and 14 pts (27%) received autologous bone marrow (BM) with 4-hydroxyperoxycyclophosphamide (4-hc) purging in 9 cases (17%). The median age was 49 yrs (range: 29–65). Results: There was 1 treatment-related death during the first 100 days. After ASCT, 36 pts (69%) achieved a CR, 2 (4%) had a PR, and 7 (13%) had stable disease. Among those in CR, 20 (56%) had a CR pre-ASCT, 14 (41%) had a lesser response, and 1 (3%) was chemo-resistant. Median follow-up (f/u) of survivors was 5.3 yrs (range: 1.7 months to 12.4 yrs). The median overall survival (OS) has not yet been reached. The median event-free survival (EFS) is 3.4 yrs (range: 1.7 months to 12.4 yrs). Among complete responders, more than 50% are disease free at last follow-up (range 1.7 months to 12.1 yrs). Variables favorably affecting EFS and OS are age < 60 yrs (p = 0.007, 0.015 respectively), achievement of a CR after ASCT (p = 0.002, 0.001), absence of transformation (p = 0.038, 0.017), BM vs. PSCT (p = 0.042, 0.086), and 4-hc BM purging (p = 0.044, 0.059). Number of prior regimens, response prior to ASCT, type of preparative regimen, and addition of TBI, were not significantly associated with EFS, DFS, or OS. In multivariable analysis, achievement of CR after ASCT and age < 60 yrs are the only significant predictors of EFS and OS. Adjusted for age, 53% of pts with a CR after ASCT are alive and event-free at last f/u (range: 2.4 months to 12.4 yrs) (Figure 1). In contrast, the median EFS among pts without a CR is 0.5 yrs (range: 1.7 months to 5.3 yrs). Conclusion: ASCT is a reasonable therapeutic approach to FL, resulting in long term EFS for some pts, even with relapsed, refractory and/or transformed disease. In our experience, significant predictors of EFS and OS after ASCT are complete response and age <60. The appropriate application and timing of ASCT in the management of pts with FL needs to be further evaluated in randomized, controlled clinical trials. Figure Figure

Abstract Abstract 3064 Relapse of AML after allogeneic stem cell transplantation (alloSCT) has a very poor prognosis. Salvage re-induction chemotherapy leads to clinical remissions in a substantial number of patients, but these remissions tend to be of short duration. In contrast, donor lymphocyte infusions (DLI) have the potential to effect long-lasting remissions, but the interval of several weeks to months that is required to develop a DLI-induced anti-leukemia response may prevent efficient control of a highly proliferative leukemia. In addition, a high tumor burden may suppress the immune response. In contrast, the combination of efficient cytoreduction by chemotherapy with DLI administered in rapid succession under circumstances favoring the development of an early and profound immune response might have the potential to eradicate otherwise resistant leukemia cells. We therefore adopted an institutional therapeutic strategy for relapsed myeloid leukemia post-allogeneic SCT based on administration of DLI at the anticipated end of the neutropenic phase after salvage re-induction chemotherapy. At this time point, the high prevalence of a pro-inflammatory milieu should favor the induction of the immune response, and an expected state of lymphopenia should promote the expansion of infused T cells by homeostatic proliferation. If 3 weeks after DLI no graft versus host disease (GvHD) was observed, the potential anti-leukemia immune response was further amplified by treatment with interferon- α (IFN- α) until GvHD occurred. Between January 2000 and December 2009 44 patients with relapsed myeloid malignancy after alloSCT were treated at our hospital. Pre-transplant diagnoses were AML n=40, CMML n=1 and MDS n=3. Median time from SCT to relapse was 187 days. Median follow-up after relapse was 3.1 years. 5 patients had a smouldering relapse (<10% bone marrow blasts) and 39 patients had an overt relapse. Of 39 patients with overt relapse, 7 patients (18%) did not receive re-induction therapy due to poor performance status (n=5) or patient choice (n=2). 32 patients received remission-induction therapy consisting of gemtuzumab ozogamycin (n=9), cytosine arabinoside-containing chemotherapy (n=17), or both (n=6). Following this treatment, 7 of 32 patients had rapidly progressive disease during induction therapy (n=6) or died due to toxicity (n=1) and did not receive DLI. The remaining 25 patients received DLI at a dose of 5.0×10 ^6 CD3+ cells/kg for related and 2.5×10 ^6 CD3+ cells/kg for unrelated donors 3 weeks after the start of remission-induction therapy. In 16 of these patients DLI was boosted with IFN- α 3.0×10 ^6 IE once daily. This strategy resulted in acute GvHD in 17 of 25 patients (n=8 grade 1–2, n=9 grade 3–4). At 6 weeks after DLI, 16 patients had reached CR, 5 patients had failed to reach CR (2 with GvHD) and 4 suffered treatment-related mortality (3 with GvHD). Of the 16 patients in CR, 4 had no signs of GvHD and developed a second relapse during the follow-up period. Only 3 of 12 patients in CR with signs of acute GvHD at 6 weeks after DLI developed a second relapse. In total, 9 of 17 patients (53%) with acute GvHD after DLI had long term survival versus none without acute GvHD. During follow-up, 8 patients developed chronic GvHD (n=4 limited, n=4 extensive). Finally, 5 patients with an early detected smouldering relapse received DLI, which was boosted with IFN- α in 2 patients, without salvage re-induction therapy. All 5 patients developed GvHD (n=2 grade 1–2, n=3 grade 3–4) and 3 patients achieved a CR of whom 1 patient died from GvHD. Our results indicate that treatment of relapsed AML after alloSCT with salvage re-induction therapy followed by DLI at the end of the neutropenic phase during minimal residual disease, with additional boosting of the immune response with IFN- α, can result in long-term disease-free survival.

Abstract Background: The addition of a Tyrosine Kinase Inhibitor (TKI) to induction chemotherapy has improved the outcome of patients with Philadelphia chromosome positive (Ph+) acute lymphoblastic leukemia (ALL). However, the treatment related mortality and morbidity of intensive treatment increases with age. The use of a TKI alone for induction is less toxic and yields CR rates comparable to combined therapy. Eligibility for post remission hematopoietic stem cell transplantation is less likely to be compromised with TKI induction. We present a retrospective review of patients with Ph+ ALL treated at our institution with dasatinib and prednisone induction who subsequently underwent allogeneic hematopoietic stem cell transplant (allo-HSCT) as post remission therapy. Methods: We retrospectively identified 15 patients with Ph+ ALL treated at our institution between February 2012 and June 2015. Patients received induction therapy with dasatinib at 100 mg or 140mg daily till complete hematological response. Prednisone 60 mg/m2/day (capped at 120 mg daily) was administered until day 24 and then tapered and stopped at day 32. Intrathecal chemotherapy with MTX and Ara-C were administered twice during the induction period. Dasatinib dose reduction/discontinuation was permitted for non-hematological toxicity. Patients who achieved remission proceeded to allo-HSCT if a suitable HLA-matched donor was available. Patients who did not have a suitable HLA matched donor received TKI + POMP maintenance. We calculated CHR, CCyR, disease-free survival (DFS) and overall survival (OS). Results: The median age of patients treated with dasatinib plus prednisone was 62 years (range: 19-73). Baseline patient and disease characteristics are summarized in Table 1. Median WBC count was 22.5 x 109/L. Fourteen of 15 patients treated with dasatinib achieved a CHR (93.3%), 1 patient did not undergo a bone marrow biopsy but had normal blood counts. Median time to CHR was 42 days (range: 22-69). CCYR was obtained in 11 patients (73%) and MMR was achieved in 5 patients (33%). No patient died during induction therapy. The 14 patients who were in CHR after induction, underwent allo-HSCT (n=7), are being evaluated for allo-HSCT (n=3), were unable to undergo allo-HSCT due to a high comorbidity index and/or lack of a suitable donor (n=3) or were lost to follow-up (n=1). Of the 3 patients who were unable to undergo allo-HSCT, 2 patients continue on dasatinib maintenance and 1 patient takes ponatinib. Of 8 patients not yet transplanted 3 relapsed, while only 1 relapse was seen in 7 patients who underwent allo-HSCT. Median DFS was 315 days (range: 57-1061) and median OS was 354 days (range: 107-1082) corresponding Kaplan Meier curves for OS and DFS are shown below. Conclusions: In our adult Ph+ ALL patients induction therapy with dasatinib and prednisone was effective and well tolerated. Patients achieving CHR were able to undergo allo-HSCT with curative intent. This strategy retrospectively appears equal or better than results with induction chemotherapy of conventional variety.

4007 Background: The MOSAIC study was designed to evaluate the effects of the FOLFOX4 regimen (5-FU/LV + oxaliplatin) on 3- year disease free survival (DFS) probability in patients with stage II and III colon cancer. Methods: Patients (n=2246) with completely resected stage II (40%) or III (60%) colon cancer were randomly assigned to receive 5-FU/LV (LV5FU2) or FOLFOX4 every 2 weeks for 12 cycles. Results: Results for the primary endpoint of the study (for the overall population, with a median follow-up [FU] of 3 years), showed a significant benefit in DFS for the FOLFOX4-treated patients (78.2% vs 72.9%; HR: 0.77, p=0.002) (André et al, NEJM, 2004). Patients were followed beyond the 3-year cut-off for DFS and overall survival (OS) updates. Final DFS, at 5 years FU, are consistent with earlier results (HR: 0.80, p = 0.003). In addition, at a median FU of 6 years, the study demonstrates a significant benefit in OS for the stage III patients. Summary of OS results (median FU 6 years) Long-term safety update shows no increase in the rate of secondary cancer (5.0% in both treatment arms). Conclusions: These results confirm the benefit of the FOLFOX4 regimen in adjuvant colon cancer patients. [Table: see text] No significant financial relationships to disclose.

144 Background: The aim of this study is to evaluate the long-term clinical and oncologic outcome of ESD for differentiated EGC of an expanded indication compared to surgical resection. Methods: Retrospective analyses were performed in patients who underwent ESD or surgical resection for EGC of an expanded indication from 2006 and 2008 in Incheon St. Mary’s Hospital, Seoul St. Mary’s Hospital, Yeouido St. Mary’s Hospital, and St. Paul’s Hospital. First arm study was performed according to pre-ESD diagnosis including pathologic diagnosis and endoscopic findings. Second arm study was obtained from post-ESD final pathologic result. All the patients were checked with endoscopy and stomach CT regularly at least 5 years. Clinical outcomes, disease free survival and overall survival were compared between the ESD group and surgical resection group in each arm. Results: In first arm study, 41 patients who received ESD and 106 patients who received surgical resection were enrolled. Metachronous recur was found in 4 patients among ESD group and in 2 patients among surgical resection group during the follow up period. There was no local recurrence in both groups. The disease free survival was not different between the two groups (ESD vs surgical resection; 87.8 vs 95.3%, p=0.291). The 5-year overall survival rate was 100% in both groups. In second arm study, 74 patients who received ESD and 165 patients who received surgical resection were enrolled. Metachronous recur was found in 5 patients among ESD group and in 2 patients among surgical resection group during the follow up period. Local recurrence did not occur in both groups. Surgical resection group was superior to ESD group in disease free survival (97.6% vs 87.6%, p=0.002). The 5-year overall survival rate was 100% in both groups. Conclusions: ESD for EGC might be acceptable considering the overall survival rates. However, intensive surveillance should be performed to find the metachronous recur after ESD.
