Abstract BACKGROUND: To compare the survival outcome between radical hysterectomy and simple hysterectomy with implants radiation in patients with stage II endometrial cancer.METHODS: This is a retrospective cohort study. We identified 1349 patients diagnosed with stage II endometrial cancer from Jan 1, 1988 to Dec 31 2015 in the Surveillance, Epidemiology, and End Results. Patients were divided into two groups based on the primary treatment (simple hysterectomy combined with brachytherapy or radical hysterectomy). The primary outcome was the rate of overall survival and cause-specific survival of two groups.RESULTS: A total of 1349 patients were enrolled in the study, 117(7.35%) patients received radical hysterectomy and 460 patients who received simple hysterectomy and vaginal brachytherapy were selected as control. All patients received external beam radiation therapy after the surgery. Overall, the median follow-up duration was 82.77±1.44months (95%CI: 79.94-85.61months). There was no difference in the baseline information between two groups, including ages, ethnicity, and rates of histologic subtypes. The 5-year mortality was 62.31% among women who underwent radical hysterectomy which was lower than 78.48% among those who underwent simple hysterectomy and vaginal brachytherapy (HR, 2.22; 95% CI, 1.52 to 3.24; P <0.001 by the log-rank test). Women who underwent radical hysterectomy also had shorter 5-year cause-specific survival (74.60 vs.85.38%; HR, 1.91; 95% CI, 1.13 to 3.23; P =0.01 by the log-rank test) than those who underwent simple hysterectomy and vaginal brachytherapy. However, the negative outcomes were further validated in patients with high-risk endometrial cancer, not in patients with grade 1-2 low-risk EC both on cause-specific survival and overall survival. Grade 3 low-risk endometrial cancer was only found with lower overall survival not cause-specific survival.CONCLUSIONS: This study revealed that in patients’ stage II high-risk endometrial cancer, radical hysterectomy radiation was associated with shorter overall survival and cause-specific survival than simple hysterectomy and vaginal brachytherapy.

ObjectivePreclinical data and recent epidemiological studies suggest that statins have antiproliferative and antimetastatic effects in various cancer cells, and reduce cancer mortality and recurrence. We study the effect of statin use on survival outcomes and recurrence rates in patients with endometrial cancer with high-risk histology.Materials and MethodsAll patients receiving definitive therapy for high-risk endometrial cancer from 1995 to 2014 were retrospectively reviewed. Health characteristics at baseline were collected, and statin use was determined from medical records. Overall survival (OS) and progression-free survival (PFS) were estimated using the Kaplan-Meier method and compared using the log-rank test. Cox proportional hazards regression models were used for univariate and multivariate analysis to determine independent factors associated with OS and PFS.ResultsA total of 199 patients were included in the study, of which 76 were hyperlipidemic and 50 used statins. The median follow-up time was 31 months from time of diagnosis. Hyperlipidemic patients who used statins had improved OS compared with hyperlipidemic patients not using statins (hazard ratio, 0.42; 95% confidence interval, 0.20–0.87;P= 0.02). Statin use was also associated with improved PFS (hazard ratio, 0.47; 95% confidence interval, 0.23–0.95;P= 0.04) on multivariate analysis. Hyperlipidemic patients who used statins had borderline improved freedom from local failure compared with hyperlipidemic cases not using statins (P= 0.08, log-rank test). Statin use was not found to be associated with improved cancer-specific mortality.ConclusionsStatin use is independently associated with significant improvements in PFS for the overall group and PFS and OS in the hyperlipidemic group.

Abstract The classification of CLL patients according to the somatic hypermutation status (SHM) of the immunoglobulin heavy variable (IGHV) genes, namely mutated (M-CLL) versus unmutated (U-CLL), reflects fundamental differences in disease biology and clinical course. Realizing this, here we followed a compartmentalized approach and addressed the issue of prognostication separately for M-CLL and U-CLL. In a multi-institutional cohort of 2366 patients [M-CLL, n=1364 (58%); U-CLL, n=1002 (42%)] consolidated within ERIC, the European Initiative in CLL, we assessed the clinical impact of 'traditional' (age and clinical stage at the time of diagnosis, gender, CD38 expression, FISH detected abnormalities included in the Döhner hierarchical model of cytogenetic aberrations), and novel prognosticators (recurrent mutations within the TP53, SF3B1, NOTCH1, MYD88, and BIRC3 genes; IGHV gene usage; membership in stereotyped subsets) within M-CLL and U-CLL. Our statistical approach was based both on Cox regression models and recursive partitioning algorithms; internal validation was performed via bootstrapping procedures. Given the retrospective nature of our study, time-to-first-treatment (TTFT) was the primary endpoint. As expected, M-CLL exhibited significantly longer TTFT compared to U-CLL [median TTFT: not yet reached (M-CLL) vs 1.9 years (95% CI: 0.01-12.3 years, U-CLL), p<0.0001]. Advanced clinical stages (Binet B-C) were associated with shorter TTFT in both M-CLL and U-CLL; a significantly worse outcome was also identified for Binet C versus Binet B cases (p<0.0001). Binet A patients received our special focus, representing 90% and 67% of M-CLL and U-CLL studied cases, respectively. Amongst Binet A M-CLL cases, TP53 aberrations [TP53abs, deletions of chromosome 17p, del(17p) and/or TP53 mutations], stereotyped subset #2 membership and trisomy 12 were identified as equally adverse prognostic indicators [median TTFT: 5.5 (95% CI: 0.2-12.8), 4 (95% CI: 0.6-6.8) and 7.3 (95% CI: 0.7-13.4) years, respectively; p-value: non-significant when applying the log-rank test for all paired comparisons); of note, TP53abs were mutually exclusive with the other two features. Amongst Binet A U-CLL cases, TP53abs, SF3B1 mutations and deletion of chromosome 11q [del(11q)] had an overall similar adverse impact [median TTFT for TP53abs, SF3B1 mutations and del(11q): 1.8 (95% CI: 0.01-4.4), 2 (95% CI: 0.01-7.7) and 2.1 (95% CI: 0.01-8.1) years, respectively, p-value: non-significant when applying the log-rank test for all paired comparisons]. Within the remaining Binet A U-CLL cases [i.e. those lacking TP53abs and/or SF3B1 mutations and/or del(11q)], the only parameter associated with shorter TTFT was male gender (median TTFT: 3.5 years, 95% CI: 0.5-8.1 years). Based on these findings, we developed two prognostic indices for assessing TTFT tailored specifically to M-CLL and U-CLL, respectively. Within M-CLL (Figure 1A), 4 subgroups were identified: (i) very high risk: Binet C with identical 5- and 10-year treatment-probability (TP) of 92%; (ii) high risk: Binet B, 5y-TP and 10y-TP: 64% and 84%, respectively; (iii) intermediate risk: Binet A with one of the following: TP53abs or +12 or subset #2 membership, 5y-TP and 10y-TP: 40% and 55%, respectively; and (iv) low risk: Binet A nonTP53abs/+12/subset#2, 5y-TP and 10y-TP: 12% and 25%, respectively. Within U-CLL (Figure 1B), 5 subgroups were identified: (i) very high risk: Binet C with 5- and 10-year TP of 100%; (ii) high risk: Binet B, identical 5y-TP and 10y-TP: 90% and 100%, respectively; (iii) intermediate risk: Binet A with one of the following: TP53abs or SF3B1 mutations or del(11q), 5y-TP and 10y-TP: 78% and 98%, respectively; (v) low risk: Binet A, male nonTP53abs/SF3B1mut/del(11q), 5y-TP and 10y-TP: 65% and 85%, respectively and (iv) very low risk: Binet A, female nonTP53abs/SF3B1mut/del(11q), 5y-TP and 10y-TP: 45% and 65%, respectively. In conclusion, we identified clinicobiological parameters with distinct prognostic implications for M-CLL and U-CLL. These parameters were used in order to develop prognostic indices tailored to SHM status that were found capable of distinguishing subgroups with markedly different outcomes. We argue that such a compartmentalized approach may supersede previous attempts, thus overcoming the pronounced heterogeneity of CLL and optimizing prognostication.

28 Background: Infive publishedRCTs, dose-escalated external beam radiation therapy (EBRT) for prostate cancer resulted in improved biochemical and local control. However, the question of whether dose escalation improves overall survival (OS) remains unanswered. We examined OS among men with non-metastatic prostate cancer undergoing EBRT in the modern era. Methods: Using the National Cancer Database (NCDB), we conducted non-randomized comparative effectiveness studies of dose-escalated versus standard-dose EBRT in men diagnosed from 2004-2006 in three analytic cohorts defined by NCCN risk category: low- (N=12,848), intermediate- (N=14,966) or high-risk (N=14,587) prostate cancer. We categorized patients in each risk cohort into 2 treatment groups: standard-dose (68.4 Gy to <75.6 Gy) or dose-escalated (≥75.6 Gy to 90 Gy) EBRT. The primary outcome was time to death from any cause, measured from diagnosis to NCDB date of death or end of follow-up (December 31, 2011). We compared OS between treatment groups in the three analytic cohorts using Cox proportional hazard models. Inverse probability weighted propensity score methods were used to balance differences between treatment groups in age, race, year of diagnosis, AJCC T- and N-stage, PSA, Gleason score, androgen deprivation therapy, IMRT use, comorbid disease, income, insurance, urban/rural location, facility type and facility volume. In secondary analyses, we evaluated dose response for survival by categorizing dose in approximately 2 Gy increments. Results: Median follow up for survivors was between 73 and 74 months in all three risk cohorts. Dose-escalated EBRT was associated with improved survival in the intermediate-risk (adjusted HR 0.81, 95% CI 0.77 and 0.85, p<0.0001) and high-risk groups (aHR 0.85, 95% CI 0.81 and 0.89, p<0.0001), but not the low-risk group (aHR 0.99, 95% CI 0.92-1.06, p=0.803). For every incremental ~2Gy increase in dose, there was a 9% (95% CI 6% – 11%, p<0.0001) and 7% (95% CI 3% - 10%, p=0.004) reduction in the hazard of death for intermediate- and high-risk patients, respectively. Conclusions: Dose-escalated EBRT is associated with improved survival in men with intermediate- and high-risk, but not low-risk, prostate cancer.

188 Background: Androgen deprivation therapy (ADT) can cause considerable toxicity and may influence outcome. The study assessed the impact of testosterone recovery (TR) on survival after ADT and definitive radiotherapy in two independent cohorts. Methods: Two hundred and forty-four patients (high risk JHH cohort N=106, T1c-T3N0M0 [A], locally advanced OUH cohort N=138, T1c-T4N0-1M0 [B]) with adenocarcinoma of the prostate were included in this retrospective analysis. Short and long-term ADT was given (median 12 months A, 24 months B, respectively,) and along with conformal external beam radiation 76-80 Gy given to the prostate in cohort A, 74 Gy prescribed in cohort B and 46-50 Gy to the whole pelvis. Testosterone levels were measured at the end of ADT and at biochemical relapse. TR was defined as ≥ 9 nmol/L. Kaplan Meier plots were generated for overall survival (OS) and cause-specific survival (CSS) stratified by TR, in addition to patient characteristics median time to TR and FU were calculated. Results: The median age in the A cohort was 66.7 years and 64.7 years in the B group. FU was 6 years for A and 8 years in B. Patients in group A received median ADT of 12 months and 24 months in group B. The median time to TR was 1.6 yr in A and 2.5 yrs in B, respectively. Patients in group A stratified to TR showed no difference in overall survival (p=0.92)), on contrary, patients in group B showed improved overall survival depending on TR (Fig. 1, KM plot, 10 year OS 75.3% vs 59.9% p=0.034). CSS was seemed to trend towards improvement with TR for cohort A (p=0.19) and was improved in cohort B (p=0.022). The Univariate ADT length, age, and RT dose was associated with time to TR, but on multivariate analysis only longer ADT time (p = 0.03) was significantly associated with time to TR. Conclusions: TR was associated with improved OS in patients with unfavorable locally advanced disease a finding not seen in patients with high-risk disease.

Introduction: Thromboembolism (TE) is a well-known complication of cancer and its treatments. The impact of TE on survival outcomes remains unclear, especially in children. We assessed whether TE development was associated with overall survival (OS) and event-free survival (EFS) in children with acute lymphoblastic leukemia (ALL). Methods: We performed a population-based retrospective cohort study using the national registry Cancer in Young People Canada (CYP-C). Children 0-&lt;15 years of age diagnosed with ALL (2000-2018) and treated at one of 12 Canadian pediatric centers outside of Ontario were included. OS was defined as the time between the date of cancer diagnosis and death and, EFS, as the time between the date of cancer diagnosis and the date of relapse, subsequent malignancy or death (whichever came first). Patients were categorized as to whether they experienced a radiologically-confirmed TE during treatment graded 3, 4 or 5 as per the Common Terminology Criteria for Adverse Events v.4 (i.e. requiring medical treatment, life-threatening or fatal). Only TEs that occurred before relapse or subsequent malignancy were considered. The Kaplan-Meier survival method estimated the 5-year OS and EFS of children with TE compared to those without TE. Univariate and multivariable Cox regression models were used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of death or an event between groups, adjusted for age, sex, and leukemia risk group. A sub-analysis stratified the analysis by leukemia risk group. Results: The study included 2,208 children (median age: 4 years [interquartile range: 2-7 years], 54.9% male). Precursor B-cell ALL was the most common diagnosis (1,789, 89.1%). Patients were stratified as standard/low risk ALL in 58.0% of cases, and high/very high risk ALL in 42.0%. Of these, 121 (6.0%) developed a TE, at a median time of 100 days (interquartile range: 30-183 days) after cancer diagnosis. Eight patients (0.4%) had a life-threatening or fatal TE. Patients with TE were more likely to be aged 10 years or older, to present with T-cell ALL, and to have high risk leukemia. The 5-year OS (95% CI) of patients with and without TE was 80.2% (72.9-87.5%) and 93.7% (92.5-94.9%) respectively (log-rank test: p&lt;0.001, Figure 1). The adjusted HR (95% CI) of death in children with TE was 2.09 (1.33-3.27, p=0.001). Similarly, as shown in Figure 2, the 5-year EFS (95% CI) of patients with and without TE was 68.7% (59.7-77.7%) and 88.6% (87.1-90.1%), respectively (log-rank test: p&lt;0.001). The adjusted HR (95% CI) of an event was 2.01 (1.39-2.90, p&lt;0.001). When stratified by leukemia risk group, no statistically significant difference was seen in standard/low risk ALL for both OS and EFS but TE was associated with a significantly lower OS and EFS in children with high/very high risk ALL (Table 1). In this group, the increased risk of death was attributable to both deaths following relapsed disease (HR [95% CI]: 2.37 [1.39-4.04]) and death not following relapse (HR [95% CI]: 2.93 [1.35-6.35]). Sensitivity analyses in which 1) patients with very high risk ALL were removed and 2) only grade 3 or 4 TE were considered showed similar results. Conclusions: Clinically relevant TE led to a statistically significant reduction in OS and EFS in children with high risk/very high risk leukemia. Further research is needed to assess whether TE prevention may improve anti-cancer outcomes. Disclosures Brandao: Boehringer Ingelheim: Other: Member of a paediatric expert working group.

Abstract BACKGROUND Chronic Lymphocytic Leukemia (CLL) is one of the most common hematological malignancies in Western countries. The disease is characterized by heterogeneous clinical course and outcome. During the last 15 years several clinical, biological and molecular prognostic factors have been identified, validated and some of them are currently used in patients' and treatment management. To improve the predictive accuracy of these markers, they have been combined into prognostic indexes (W. Wierda, JCO 2011, D. Rossi, Blood 2012, J. Bahlo, Haematologica 2015). Werecently proposed the Integrated CLL Scoring System (ICSS) based on cytogenetic abnormalities by FISH, IGHV mutational status and CD38 expression from 212 patients (A. Visentin et al, Clin Lymph Myeloma & Leuk 2015). The aim of this study was to validate the prognostic power of our index into a larger series of 420 CLL patients. METHODS 420 CLL patients referred to the Hematology Unit of Padua University Hospital from 1989 to 2015 were recruited in this study. According to ICSS, patients were classified as: low-risk, those patients with 13q deletion or normal FISH, IGVH mutated and CD38<30%; high-risk, subjects with 17p or 11q deletion and/or IGVH unmutated and CD38>30%; intermediate-risk, all remaining patients. Treatment free survival (TFS) was calculated as time from diagnosis to treatment (event), death or last known follow-up (censored). Overall survival (OS) was calculated from the date of diagnosis to death for any cause (event) or last known follow-up (censored). TFS and OS were compared with log-rank test and plotted using Kaplan-Meier method. The predictive accuracy of ICSS was evaluated by the Harrel's concordance index (c-index); a value >0.5 implies a good predictive ability. RESULTS The median age of our cohort was 62 years; 64% were male and 85% were Binet stage A at diagnosis. Cytogenetic analysis by FISH showed that 41 patients harbored 17p deletion, 50 11q deletion, 236 13q deletion, 44 trisomy 12 and 49 had normal FISH. 236 (56%) patients had IGHV gene homology >98% (i.e. mutated IGHV) and 103 (25%) expressed more then 30% of CD38. According to ICSS 202 (48%) subjects were classified as low-risk, 83 (20%) intermediate-risk and 135 (32%) high-risk. After a median follow-up of 81 months, the median TFS for ICSS classes of risk were 211, 70 and 27 months (log-rank test, p<0.0001, Figure 1A). The estimated 10-year TFS were 61%, 37% and 10% for low, intermediate and high-risk patients. The median OS were 213 and 136 months for intermediate and high-risk, while it was not reached for low-risk patients (Log-rank test, p<0.0001, Figure 1B). After 10 years from diagnosis the estimated OS were 88%, 79% and 57%, respectively. These data were confirmed by a multivariate analyses. In fact, high-risk patients had 5.3 and 4.0 times risk of start treatment and death than low-risk subjects, respectively (p<0.0001). This model was statistically internally validated, showing c-indexed of 0.712 and 0.693 for TFS and OS, respectively. In multivariate analyses, variables confirmed to predict adverse prognosis were male gender (p=0.0183), age>65years (p<0.0001), Rai III-IV (p=0.0025), Binet C (p=0.0002), 17p deletion (p=0.0002), TP53 abnormalities (p=0.0051), unmutated IGVH (p<0.0001), CD38>30% (p=0.0044) and high-risk ICSS (p<0.0001). CONCLUSIONS We herein provide evidence of the prognostic power and feasibility of ICSS into a large population of CLL patients. The use of this prognostic index could help physician into follow-up schedule, since high-risk patients should be monitored more often given the estimated increased risk of progression.

BackgroundIt is well known that neoadjuvant radiotherapy could reduce local recurrence followed by surgical resection. However, evidence about oncologic efficacy of radiotherapy and survival benefit of adjuvant chemotherapy after neoadjuvant radiotherapy is still lacking.MethodsThis retrospective propensity score-matched cohort study identified patients with pathologically confirmed rectal cancer and receiving surgery with curative intent from the Surveillance, Epidemiology, and End Results database from 2004 through 2014. Overall survival was compared using the stratified log-rank test. Multivariate Cox regression analysis was used for identifying risk factor and developing prediction nomogram.ResultsA total of 22,008 (11,004 for each group) propensity-matched patients were identified. In the context of receiving adjuvant chemotherapy after surgical resection, there was no significant difference in terms of overall survival between surgery alone group and neoadjuvant radiotherapy and surgery group, whether for stage I (log-rank test p = 0.467), stage II (log-rank test p = 0.310), or stage III (p = 0.994). In case of receiving a prior combination therapy of neoadjuvant radiotherapy and surgery, the following adjuvant chemotherapy could significantly improve overall survival for patients with stage I (log-rank test p &lt;0.001), stage II (log-rank test p = 0.038), and stage III (log-rank test p = 0.014). Nomogram integrating clinicopathologic factors was developed to predict survival benefit associated with neoadjuvant radiotherapy. Calibration and ROC curves validated promising performance for the nomogram.ConclusionPatients with rectal cancer underwent neoadjuvant radiotherapy yield acceptable outcomes and are more likely to benefit from adjuvant chemotherapy in terms of overall survival. These data would be evidential for advocating consistency in guideline adherence to the use of adjuvant chemotherapy after neoadjuvant radiotherapy.

Abstract We attempted to establish a magnetic resonance imaging (MRI)-based radiomic model for stratifying prognostic subgroups of newly diagnosed glioblastoma (GBM) patients and predicting O (6)-methylguanine-DNA methyltransferase promotor methylation (pMGMT-met) status of the tumor. Preoperative MRI scans from 201 newly diagnosed GBM patients were included in this study. A total of 489 texture features including the first-order feature, second-order features from 162 datasets, and location data from 182 datasets were collected. Supervised principal component analysis was used for prognostication and predictive modeling for pMGMT-met status was performed based on least absolute shrinkage and selection operator regression. 22 radiomic features that were correlated with prognosis were used to successfully stratify patients into high-risk and low-risk groups (p = 0.004, Log-rank test). The radiomic high- and low-risk stratification and pMGMT status were independent prognostic factors. As a matter of fact, predictive accuracy of the pMGMT methylation status was 67% when modeled by two significant radiomic features. A significant survival difference was observed among the combined high-risk group, combined intermediate-risk group (this group consists of radiomic low risk and pMGMT-unmet or radiomic high risk and pMGMT-met), and combined low-risk group (p = 0.0003, Log-rank test). Radiomics can be used to build a prognostic score for stratifying high- and low-risk GBM, which was an independent prognostic factor from pMGMT methylation status. On the other hand, predictive accuracy of the pMGMT methylation status by radiomic analysis was insufficient for practical use.
