135 Background: Squamous cell carcinoma (SCC) has been traditionally linked to a better response to treatment and overall survival when compared to adenocarcinoma (AC) of the esophagus. Recent advances in staging, neoadjuvant therapy (NAT) and increasing surgical management of patients with EC have led to improved overall survival of these patients. The aim of this study is to analyze the impact of squamous histology on treatment response and long term outcomes in patients with distal EC. Methods: A retrospective review of patients who underwent esophagectomy for EC at a single institution over a 16 year period (1999-2015) was performed. Pre-operative clinical parameters, stage as well as oncologic management were compared between SCC and AC of the distal esophagus and the difference in response to treatment and overall survival were analyzed using descriptive statistics. Results: Esophagectomy was performed on 945 patients with EC of which 839 patients (89%) had distal EC. The mean age of this group was 63 years and majority were male (87%). Histology was SCC for 78 patients (9.4%) and AC for 747 patients (90.6%). Pretreatment clinical stage was similar between groups (p = 0.16). NAT administration was similar between groups (p = 0.13). Although SCC patients had higher rate of complete response (54% v/s 36%, p = 0.01) we found no difference in the overall survival after surgery (33 months for SCC v/s 40 months for AC, p = 0.72) irrespective of whether they received NAT (p = 0.95) or not (p = 0.55). Conclusions: Squamous cell histology had a favorable impact on the rate of pathologic response for patients with distal EC; however, this improvement did not alter their overall survival. This could provide an insight into the decreasing significance of the histology in the management and expectations from treatment of EC while emphasizing the continuing need for multimodality therapy to assure good outcomes on these patients.

The Impact

The goal of treatment for multiple myeloma (MM) is to improve patients' long-term outcomes. One important factor that has been associated with prolonged progression-free and overall survival is the quality of response to treatment, particularly achievement of a complete response (CR). There is extensive evidence from clinical studies in the transplant setting in first-line MM demonstrating that CR or maximal response post-transplant is significantly associated with prolonged progression-free and overall survival, with some studies demonstrating a similar association with postinduction response. Supportive evidence is also available from studies in the nontransplant and relapsed settings. With the introduction of bortezomib, thalidomide, and lenalidomide, higher rates of CR are being achieved in both first-line and relapsed MM compared with previous chemotherapeutic approaches, thereby potentially improving long-term outcomes. While standard CR by established response criteria has been shown to have differential prognostic impact compared with lesser responses, increasingly sensitive analytic techniques are now being explored to define more stringent degrees of CR or elimination of minimal residual disease (MRD), including multiparameter flow cytometry and polymerase chain reaction. Demonstrating eradication of MRD by these techniques has already been shown to predict for improved outcomes. Here, we review the prognostic significance of achieving CR in MM and highlight the importance of CR as an increasingly realizable goal at all stages of treatment. We discuss clinical management issues and provide recommendations relevant to practicing oncologists, such as the routine use of sensitive techniques for assessment of disease status to inform evidence-based decisions on optimal patient management.

Abstract Abstract 5115 INTRODUCTION. Even with the introduction of novel therapeutic agents, including thalidomide, bortezomib, and lenalidomide, multiple myeloma (MM) is an incurable disease. Deeper responses, such as complete response (CR) and very good partial response (VGPR), are major goals of treatment to obtain long-term overall response (OS) and progression-free response (PSF) in patients with MM. Recent large randomized retrospective studies also suggested improved OS and PFS in patients who achieved deeper responses. However, the prognostic impact of achieving CR or VGPR remains controversial. In addition, these studies included selected patients that may not be representative of the general population. Therefore, we analyzed cases in our database to evaluate the impact of treatment response on the outcome of consecutive patients with symptomatic MM who were treated with chemotherapeutic regimens containing novel agents over the past 6 years at our institution in Kamogawa City, Japan. PATIENTS AND METHODS. We included 97 consecutive patients treated at our institution between April 2005 and May 2011. The study population consisted of 56 male and 41 female patients with a median age of 70 years old (range: 45 −90). Due to the rapid changes in treatment modality and government approval of novel agents in myeloma during this period, initial treatment could not be uniformly categorized, but all patients received chemotherapy regimens containing at least one novel agent, including thalidomide, bortezomib, and lenalidomide. These patients were thought to be more representative of the general myeloma population. Seventy-seven (79.4%), 27 (38.6%), and 55 (56.7%) patients received bortezomib-, lenalidomide-, and thalidomide-containing regimens, respectively. Treatment responses were assessed using the International Myeloma Working Group (IMWG) criteria with minor modifications, and the best response to treatment during the course of disease was evaluated. Immunofixation test and serum free light chain measurements were performed for confirmation of CR and stringent CR. OS was calculated from the time of diagnosis until the date of death from any cause or the date on which the patient was last known to be alive. Univariate and multivariate analyses were performed for the following variables: age at diagnosis, International Staging System (ISS), and best response achieved. RESULT. The median age of patients was 71 y.o. (range: 49 −90 y.o.), and the male to female ratio was 56:41. The best responses to treatment were as follows: CR was obtained in 19 cases (19.6%), VGPR in 29 (29.9%), partial response (PR) in 34 (35.0%), and stable disease (SD) or less in 15 (15.4%). Baseline characteristics according to best response achieved in patients who achieved CR, VGPR, PR, and SD or less were similar among the patients ≥70 y.o. vs. ≤70 y.o. Patients' age has no impact on the response to treatment. With a median follow-up of 25 months, Kaplan–Meier estimated 3-year and 5-year overall survival (OS) rates were 67.2% and 35.0%, respectively. The 3- and 5-year OS were 100% in patients with CR, which were significantly superior in patients with VGPR (3-y 70%, 5-y 55.0%) and PR (3-y 60%, 5-y 23.0%). The 3- and 5-year OS were not significantly different between patients with VGPR and PR. Normalization of FLC kappa/Lambda ratio was observed in 15 of 19 (80%) patients with CR, 15 of 29 (51%) with VGPR, 4 of 34 (6.6%) in PR, and in none of 15 (0%) in SD or less. Patients who showed normalization of FLC kappa/Lambda ratio had significant OS benefit compared to those who did not. Proportional hazard Cox models showed that patients with ISS stage I/II had better 5-year OS rate compared to patients with stage III (51%; 20%, P = 0.005). However, there was no association between ISS stage and achievement of CR. CONCLUSION. The results of the present study highlighted the importance of achieving CR, not PR or VGPR, and normalization of FLC kappa/Lambda ratio for obtaining long-term OS in patients with MM regardless of age or ISS stage.

Background. Although mortality and morbidity of pancreatoduodenectomy (PD) have improved significantly over the past years, the impact of age for patients undergoing PD is still debated. This study is aimed at analyzing short- and long-term outcomes of PD in elderly patients. Methods. 124 consecutive patients who have undergone PD for pancreas neoplasms in our center between 2012 and 2017 were analyzed. Patients were divided into two groups: group I (<75 years) and group II (≥75 years). Demographic features and intraoperative and clinical-pathological data were collected. Primary endpoints were perioperative morbidity and mortality; complications were classified according to the Clavien-Dindo Score. Secondary endpoints included feasibility of adjuvant treatment and overall survival rates. Results. A total of 106 patients were included in this study. There were 73 (68.9%) patients in group I and 33 (31.1%) in group II. Perioperative deceases were 4 (3.6%), and postoperative pancreatic fistulas were 34 (32.1%). Significant difference between two groups was demonstrated for the ASA Score (p=0.004), Karnofsky Score (p=0.025), preoperative jaundice (p=0.004), and pulmonary complications (p=0.034). No significance was shown for diabetes, radicality of resection, stage of disease, operative time, length of stay, postoperative complications according to the Clavien-Dindo Score, postoperative mortality, pancreatic fistula, and reoperation rates. 69.9% of the patients in group I underwent adjuvant treatment vs. 39.4% of the older ones (p=0.012). Mean overall survival was 28.5 months in group I vs. 22 months in group II (p=0.909). Conclusion. PD can be performed safely in elderly patients. Advanced age should not be an absolute contraindication for PD, even if greater frailty should be considered. The outcome of elderly patients who have undergone PD is similar to that of younger patients, even though adjuvant treatment administration is significantly lower, demonstrating that surgery remains the main therapeutic option.

Quality of life (QOL) has become an important focus of hernia repair outcomes. This study aims to identify factors which lead to ideal outcomes (asymptomatic and without recurrence) in large umbilical hernias (defect size ≥9 cm2). Review of the prospective International Hernia Mesh Registry was performed. The Carolinas Comfort Scale was used to measure QOL at 1-, 6-, and 12-month follow-up. Demographics, operative details, complications, and QOL data were evaluated using standard statistical methods. Forty-four large umbilical hernia repairs were analyzed. Demographics included: average age 53.6 ± 12.0 and body mass index 34.9 ± 7.2 kg/m2. The mean defect size was 21.7 ± 16.9 cm2, and 72.7 per cent were performed laparoscopically. Complications included hematoma (2.3%), seroma (12.6%), and recurrence (9.1%). Follow-up and ideal outcomes were one month = 28.2 per cent, six months = 42.9 per cent, one year = 55.6 per cent. All patients who remained symptomatic at one and two years were significantly symptomatic before surgery. Symptomatic preoperative activity limitation was a significant predictor of nonideal outcomes at one year ( P = 0.02). Symptomatic preoperative pain was associated with nonideal outcomes at one year, though the difference was not statistically significant ( P = 0.06). Operative technique, mesh choice, and fixation technique did not impact recurrence or QOL. Repair of umbilical hernia with defects ≥9 cm2 had a surprising low rate of ideal outcomes (asymptomatic and no recurrence). All patients with nonideal long-term outcomes had preoperative pain and activity limitations. These data may suggest that umbilical hernia should be repaired when they are small and asymptomatic.

Abstract Background: PTLD is a rare and severe complication of solid organ and hematopoetic stem cell transplantation and CNS localizations are well known to be associated with an unfavourable outcome. Published data on PTLD with CNS involvement (CNS-PTLDs) are nearly inexistent and the impact of rituximab is unknown. Methods: We performed a retrospective analysis on CNS-PTLDs in two centres, the Pitié salpêtrière university hospital in Paris, France, and the Charité university hospital in Berlin, Germany, in order to have an homogeneous way to handle these diseases and to avoid biases of large national registers. PTLDs with extra-CNS localization were excluded. While attitudes for diagnosis, staging and initial immunosuppression diminution were identical, one centre largely used intravenous (iv) rituximab and radiotherapy while the other preferred high dose chemotherapy. The Pitié Salpêtrière series of 72 PTLD patients without CNS involvement served as a control population to identify specific disease characteristics of primary CNS-PTLD. Results: 24 patients with CNS-PTLD (median age 55y) have been analyzed and compared to the non-CNS PTLD group (table I). The mean follow-up of patients alive is 5 years. Primary CNS-PTLD are clearly of late onset (mean 1366 days after transplantation) with only 3/24 patients diagnosed within the first year after transplantation. There was a significant overrepresentation of renal allografts in the CNS-PTLD group as compared to PTLDs without CNS involvement, (75% vs 29%). Primary CNS-PTLDs were always of B-cell phenotype and tumors were EBV positive in 88% of cases. Treatment of primary CNS-PTLDs consisted of chemotherapy (CT) alone with high dose (HD) Mtx and/or HD AraC in 8 cases, intrathecal (it) Mtx only in 1 case and it single agent rituximab in 1 case. Rituximab has been used in combination with CT in 2 cases. Radiotherapy (RX) was used at a mean dose of 30 Gy in combination with CT in 6 patients, and in combination with rituximab in 6 patients. The overall survival of patients suffering from primary CNS-PTLD was 180 days, but some patients obtained sustained complete remissions (CR) and 11 survived more than one year [395d – 3965d]. Eight patients are alive at the time of analysis, 9 died of PTLD progression and 2 by early sepsis. The mean DFS is 1456 days. Among the 13 patients obtaining a CR, only one relapsed 6 years after his first PTLD diagnosis in an extra CNS form. Five patients died, 3 by sudden death (d60, d408, d671), one by cerebral toxoplasmosis (d703) and one by sepsis (d91). Among patients with long term survival, 5 have been treated with CT alone, 3 by RX +/− R and 3 with combined CT-RX. The role of rituximab in primary CNS-PTLD is still unclear, as only 4/9 patients treated with rituximab achieved survival, all the more so since it as been always used but once in association. Concusion: Primary CNS-PTLD is a specific entity inside the PTLD family, with a high representation of kidney grafts and EBV positive tumors. As in immunocompetent patients, long survival is possible, especially with HD CT with or without RX. The impact of rituximab seems to be reduced.

Abstract Abstract 1553 Background: Most pts with AML will achieve complete remission (CR) following therapy with cytarabine and an anthracycline. Early clearance of blasts in peripheral blood (PB) has been shown to be an important prognostic factor in acute lymphoblastic leukemia. We explored the dynamics of PB blasts in pts with AML undergoing induction chemotherapy with AI (ara-C 1.5g/m2x3d and idarubicin 12mg/m2x3d) at our institution and their impact in long-term outcomes. Patients & Methods: We reviewed the dynamics of PB blasts (i.e. PB blasts=0%) or WBC (i.e. WBC≤0.1×109/dL) clearance in pts with AML receiving AI (n=486). Patients with acute promyelocytic leukemia were excluded. Pt characteristics were as follows: median age 55 yrs (range, 19–73), pts <60 yrs 44 (30%), diploid cytogenetics (n=54, 36%), poor cytogenetics (n=57, 38%), median WBC 4.9 (range, 0.3–97.4), platelets 39 (range, 2–581), hemoglobin 8.4g/dL (range, 3.3–13.2), PB blasts (15% (range, 1–96), BM blasts 45% (1–96). Results: The overall response rate (ORR=CR+CRp) was 65% (58%+7%). Forty-four (30%) pts were resistant to induction therapy. To evaluate the dynamics of PB WBC and PB blast clearance, we divided all pts in 5 groups depending on the day they cleared their WBC or blasts from PB: group 1 (0–1 days), 2 (2–3 days), 3 (4–5 days), 4 (6–8 days), and 5 (beyond day 8). A total of 21, 34, 25, 4, and 3 pts were included in groups 1 through 5. No differences in CR rates were observed across all 5 groups according to the time of clearance of PB WBC (p=0.653). Likewise, similar median overall survival (OS) rates were observed in all 5 groups regardless of the timing of PB WBC clearance (0.2). However, the timing of PB blast clearance was associated with a distinct probability of achieving CR, being 73%, 74%, 65%, 24%, AND 60% for groups 1 through 5 (p=0.003). This translated into distinctly different median OS for the 5 groups (p=0.03) (Figure 1A). When groups 1, 2, and 3 were merged and compared with the merge of groups 4 and 5, the ORR for the resulting two new groups was 71% and 32% (p<0.001) and the corresponding median OS was 40 weeks and 75 weeks (p=0.038) (Figure 1B), suggesting that early PB clearance predicts long-term outcomes. Conclusion: We have shown in a large cohort of uniformly treated pts with AML that early clearance of PB blasts (but not WBC) is an important risk factor for achievement of CR and for OS. Clearance of PB blasts should be considered in prognostication schemas for pts with AML. Disclosures: No relevant conflicts of interest to declare.

717 Background: The role of adjuvant chemotherapy following resection in patients with rectal cancer that achieve pathologic complete response (pCR) after neoadjuvant therapy is unclear. Current data have been limited by small sample size series. This study examined the impact of adjuvant chemotherapy following pCR on overall survival in a national cohort of patients. Methods: Patients with rectal adenocarcinoma were identified in the National Cancer Data Base between 2006 and 2012. Those with locally advanced tumor (clinical stage II or III) that achieved pCR (defined as ypT0N0 in surgical specimens) after neoadjuvant chemoradiotherapy (nCRT) were included in the study. We matched by propensity score patients that received adjuvant chemotherapy (ACT) and patients that did not receive postoperative treatment (no-ACT) controlling for demographic as well as perioperative patient and tumor characteristics. Overall survival was compared using a Cox proportional hazards model. Results: We identified 2,543 patients (ACT: 732, no-ACT: 1,811 patients) with resected locally advanced rectal adenocarcinoma that achieved pCR after nCRT. Among patients that received ACT, 711 were matched with 711 patients in the no-ACT group. Adjuvant chemotherapy was associated with improved overall survival compared to no-ACT (hazard ratio[HR] = 0.46, 95% confidence interval [CI] = 0.29 – 0.75). Overall survivals at 1, 3, and 5 years in the ACT and no-ACT groups were 100% vs 98% (P=0.1), 98% vs 94% (P<0.01), and 94% vs 89% (P<0.01), respectively. In subgroup analyses, adjuvant chemotherapy improved overall survival in patients with clinical stage II (HR = 0.43, 95% CI = 0.22 – 0.85) as well as stage III tumor (OR = 0.50, 95% CI = 0.26 – 0.98). Among patients that received adjuvant chemotherapy, there was no difference in overall survival between single agent and multiagent regimens (HR = 1.37, 95% CI = 0.57 – 3.29). Conclusions: Adjuvant chemotherapy may providea small long-term survival benefit in patients with resected locally advanced rectal cancer and pCR after nCRT.

Abstract Objective The aim of this study was to determine the outcomes of patients with T3N3 esophageal cancers and determine differences between the clinical stage and pathological stage. Background Locally advanced esophageal cancer is associated with poor long-term survival. Pre-treatment and post-treatment stage may differ due to the effect of neoadjuvant therapy and inaccuracies in staging. Multimodality staging followed by discussion at an MDT is considered the gold standard. Despite this, patients can be under-staged or over-staged leading to inadequate or unnecessary treatment associated with high levels of morbidity. Methods Consecutive patients from a single unit between 2010 - 2018 were included with either clinical (cT3N3) or pathological (pT3N3) esophageal cancer. Outcomes were compared between patients that underwent transthoracic esophagectomy and radical two field lymphadenectomy with or without neoadjuvant treatment and those patients staged cT3N3 treated non-surgically (NSR). Demographics, clinical and pathological stage, histological information and outcomes were recorded. Patients were staged using the TNM 8. Results This study included 156 patients, of which 63 had non-surgical treatment, only 3 of these had radical treatment. Of the remaining 93 patients who underwent esophagectomy, 34 were cT3N3, 54 were pT3N3 and five were unchanged before and after treatment. Median overall survival (OS) for surgical cT3N3 patients was significantly longer than pT3N3 and NSR (median: NR vs 19 vs 8 months, p<0.001). Twenty-seven patients with cT3N3 had lower staging following treatment whilst 3 had a higher stage. Conclusion T3N3 disease carries a poor prognosis. Within this cohort cT3N3 disease treated surgically has a high 5-year overall survival suggesting possible over-staging and stage migration due to neoadjuvant therapy. To contrast this those not having surgery have a dismal prognosis. The impact of neoadjuvant treatment cannot be predicted and, current staging modalities may be inaccurate. Clinical stage should be used with caution when counselling patients regarding management and prognosis.
