133 Background: GC is one of the most common cancers worldwide, and has an even higher incidence rate in China. The incidence rate of GC is rising in young pts (≤ 40 years). Previous studies suggested that the percentage of female pts was higher in young pts than that in older pts. The clinical characters and potential prognostic factors have not been well described for young female pts with metastatic GC. Methods: A retrospective chart review was conducted for all GC pts treated at our institution from 1995 to 2012. Pt demographics, clinical characters, treatment related information and survival data were collected. Kaplan-Meier test was used for the survival analysis. Cox regression was conducted for uni- and multi-variate analysis. Results: In total, 1,862 pts with histologically confirmed GC were identified. Among these pts, 11.3% were young pts when first diagnosed. The male to female ratio was 2.76:1 for the whole group and 1:1.02 for young pts. Ninety-eight female pts were ≤ 40 years when diagnosed of metastatic GC. For this group, median age was 35 years (range: 19-40 years). Seventy-one (72.4%) had > 1 metastatic sites, and 85 (86.7%) received palliative chemotherapy. The median overall survival (OS) was 14.9 months (95% confidence interval [CI] 11.8-18.0 months). Seventy-six (77.6%) pts had intact primary tumor when diagnosed of metastatic disease. Compared to 22 pts who relapsed after radical surgery, OS was similar for pts presented with de novo metastatic disease (Hazard Ratio (HR) 1.03, 95% CI: 0.55 to 1.92, P= 0.9). Of these 76 pts, 36 underwent palliative gastric resection, which was associated with improved OS (15.3 vs. 9.0 months; HR 0.37, 95% CI: 0.19 to 0.74, P = 0.003). Forty-six (46.9%) pts had ovarian metastasis, and 20 had oophorectomy. Palliative oophorectomy was associated with significantly improved OS (36.6 vs. 12.4 months, HR 0.34, 95% CI: 0.14 to 0.80, P = 0.013). Conclusions: There was an increased ratio of females in young GC pts. In young female pts with metastatic GC, palliative resection of gastric primary and ovarian metastasis were associated with significantly improved OS, and should be considered in appropriate pts.

Purpose: To examine whether the combination of orbital atherectomy (OA) and drug-coated balloons (DCB) can lead to superior procedural and 2-year outcomes compared with DCB only in heavily calcified femoropopliteal (FP) lesions. Materials and Methods: A retrospective chart review was conducted to identify patients treated with DCB only or OA+DCB for de novo FP lesions at a single center over a 4-year period (2014–2017). In the observation period, 113 patients met the inclusion criteria: 63 treated with DCB only (mean age 69.0±8.6 years; 62 men) vs 50 treated with OA+DCB (mean age 70.3±7.1 years; 48 men). The OA+DCB group had higher calcification rates (78% with severe calcification vs 37% in the DCB only group). Propensity score matching (PSM) was used to adjust for baseline differences between the 2 groups. Cox regression analysis was used to compare the follow-up outcomes between lesions treated with OA+DCB vs DCB only. Results: No difference in procedural complications or success was found. After PSM adjustment, the OA+DCB group was associated with lower bailout stenting rates (39.4% vs 66.7% in the DCB only group; p=0.026). The 2 groups had similar long-term outcomes, although the OA+DCB arm had a trend toward reduced TLR rates that did not reach statistical significance. The Kaplan-Meier estimates for 2-year freedom from TLR were 76.1% for the OA+DCB group vs 55.5% for the DCB only group (p=0.109). Conclusion: OA+DCB is a safe and effective combination for the treatment of calcified FP lesions. The combined therapy decreased the bailout stenting rates in the adjusted analysis. Larger cohorts and randomized trials are needed to examine OA efficacy in FP lesions.

Background: Osteosarcoma is a rare type of bone tumor, and this study aimed to assess the clinicopathologic features and prognoses of osteosarcoma patients. Methods: Clinicopathologic and survival data of 1025 patients between 2010 and 2016, 230 between 2008 and 2009 were downloaded and analyzed from the SEER database. Patients’ survival was analyzed using the Kaplan-Meier analysis; prognostic factors were assessed using the Cox regression hazards model. The 1-, 3-, and 5-year survival rates were estimated with nomogram. Competitive risk models were used to identify prognostic risk factors related to endpoint events of osteosarcoma patients. Results: Overall, 722 samples were obtained from the extremities, 134 from the axial bones, and 119 from the cranial and mandible in SEER (2010-2016 cohort). After the preliminary diagnosis, the median survival time of patients with osteosarcoma was 39 months, and the 1-, 3-, and 5-year survival rates were 87.3%, 67.2%, and 58.0%, respectively (P < 0.001). The competitive risk model revealed no competitive risks of the endpoint event. Conclusion: Our study found out the prognostic factors in patients with Osteosarcoma by Cox regression hazards model, after that, nomogram was established to predict the 1-, 3-, and 5-year survival rates, which may help oncologists to understand the highly malignant tumor.

Abstract Abstract 2185 Background: Secondary (s)AML from MDS is more frequent in older AML patients, and associated with an overall worse outcome with standard chemotherapy than de novo AML, particularly after MDS of longer duration (1). The azanucleoside hypomethylating agents 5-azacytidine (Vidaza) and 5-aza-2′-deoxycytidine (Decitabine, DAC) are active in MDS and, as recently shown, also AML. Compared to other predictors of response to these drugs, MDS duration prior to treatment thus far has received only limited attention, with two recent publications reporting conflicting results (2, 3). To independently validate our finding that shorter duration of MDS prior to DAC treatment may be a novel predictor of poor outcome (2, 4), we now applied this parameter to a large trial of low-dose DAC in AML pts (aged >60 years and judged ineligible for standard induction chemotherapy), about half of them with sAML from MDS with variable disease duration. Patients and Methods: Comparisons of response rate (RR, i.e. CR or PR) and overall survival (OS) from start of treatment according to MDS duration (pre-specified categorization according to quartiles) were performed post-hoc in 109 patients (pts) with previously untreated sAML (median age 72 years) treated with DAC (given over 72 hours, every 6 weeks, for up to 4 courses, followed by “maintenance” with 3 daily 1-hour infusions of DAC 20 mg/m2 every 4–6-weeks). Median WBC prior to treatment was 5.200/μl, median serum LDH 279U/l, 31.2% of pts had adverse cytogenetics, 82.6% had a performance status > 1, and 80.7% had a comorbidity index (HCT-CI) >=1. Comparisons by logistic regression and Cox regression (univariate and multivariate, adjusted for other prognostic factors showing an effect in this population of sAML pts) were performed. Results: Of the 227 AML patients treated within the 00331 trial, 109 (48%) had prior MDS with known MDS duration, with a median duration of 8 (25% quartile 3, 75% quartile 25, range 1–101) mths. The overall RR in these pts was 26/109 (24%), the overall 1 yr OS rate was 31% (94 deaths). A comparison of RR according to MDS duration revealed a trend to an increase in RR with longer duration of MDS [<3: 4/25 (16%), 3–8: 5/29 (17%), 8–25: 7/27 (26%), >=25 mths: 10/28 (36%), test for heterogeneity p=0.29, test for trend p=0.06]. Similarly, when OS from start of DAC was analyzed according to this parameter, for pts with previous MDS of longer duration there was a trend to better outcome [<3: 1 yr OS rate 23%, 3–8: 28%, 8–25: 26%, >=25 mths: 46%, test for heterogeneity p=0.17, test for trend p=0.16]. When these analyses were adjusted for other prognostic factors showing an effect in this population of sAML pts (comorbidity index, sLDH with respect to RR, and performance status, comorbidity index, and white blood count with respect to OS), the results were similar (effect of MDS duration with respect to RR: test for heterogeneity p=0.35, test for trend p=0.06, and effect of MDS duration with respect to OS: test for heterogeneity p=0.04, test for trend p=0.11). Conclusion: In this large cohort of uniformly treated pts with sAML, MDS of longer duration appeared to be associated with a better outcome, even after adjusting for important other prognostic factors. These results are supported by a similar analysis of MDS pts randomized in the 06011 EORTC intergroup trial (which compares DAC to Best Supportive Care), where MDS patients with longer (>=3 mths) disease duration prior to treatment also had better outcome (4). They warrant application of this discriminator in the evaluation also of other non-intensive AML treatment modalities. References 1. Estey et al., Blood 90:2969-77, 1997 2. Wijermans et al., Ann.

The Impact

5569 Background: The CARD trial (NCT02485691) compared cabazitaxel vs. an androgen receptor targeted agent (ART; abiraterone/enzalutamide) in mCRPC previously treated with docetaxel and the alternative ART (abiraterone/enzalutamide), in any order. These post hoc analyses assessed OS from various time points and the impact of prognostic factors. Methods: Patients with mCRPC previously treated with docetaxel and progressing ≤ 12 months on prior abiraterone/enzalutamide were randomized 1:1 to cabazitaxel (25 mg/m2 IV Q3W + daily prednisone + prophylactic G-CSF) vs. abiraterone (1000 mg PO + daily prednisone) or enzalutamide (160 mg PO). OS was calculated from date of diagnosis of metastatic disease, date of mCRPC, and start of 1st, 2nd or 3rd life-extending therapy (LET). A stratified multivariate Cox regression analysis assessed the impact of 14 prognostic factors on OS using a stepwise model selection approach with a significance level of 0.10 for entry into the model and 0.05 for removal. Results: In the CARD study (N = 255), median OS was longer with cabazitaxel vs. abiraterone/enzalutamide (13.6 vs 11.0 months; HR 0.64, 95% CI 0.46–0.89; p = 0.008). OS was numerically improved for cabazitaxel vs. abiraterone/enzalutamide when assessed from the time of diagnosis of metastatic disease or mCRPC, or from start of 1st or 2nd LET (Table). In the multivariate analysis, low hemoglobin, high baseline neutrophil to lymphocyte ratio, and high PSA values at baseline were associated with worse OS. In presence of these factors, the OS benefit observed with cabazitaxel versus abiraterone/enzalutamide remained significant (HR 0.63, 95% CI 0.42–0.94, p = 0.022). Conclusions: Cabazitaxel numerically improved OS vs. abiraterone/enzalutamide in patients with mCRPC previously treated with docetaxel and the alternative ART (abiraterone/enzalutamide), whatever the time point considered. The robustness of this OS benefit was confirmed by stratified multivariate analysis. Sanofi funded. Clinical trial information: NCT02485691 . [Table: see text]

5525 Background: The common HSD3B1 (1245A > C) germline variant is associated with increased de-novo synthesis of androgens and worse outcomes in men treated with androgen-deprivation therapy in metastatic hormone sensitive prostate cancer. The aim of this study is to determine the role of this polymorphism on treatment outcomes for AA and ENZA in patients with mCRPC. Methods: A total of 547 patients treated with AA or ENZA for mCRPC from two prospective cohorts; cohort 1 included 202 from British Columbia (Canada) and cohort 2 enrolled 345 patients from the Spanish study PROREPAIR-B. HSD3B1 genotype was determined by targeted sequencing in cohort 1 and by Taqman SNP genotyping assay in cohort 2. Associations between HSD3B1 genotypes and (TTPP), time to progression (TTP) and overall survival (OS) were evaluated via univariate COX regression. Multivariate analysis was performed to determine the independent association of each covariate. Results: The proportions of patients with a homozygous wild-type HSD3B1 (AA), heterozygous (AC) and homozygous variant (CC) genotype were respectively 45.6%, 39.4% and 15%. As expected, known prognostic factors for mCRPC such as hemoglobin, alkaline phosphatase (ALP), LDH, PSA at baseline as well as site of metastasis were significantly associated with TTPP and TPP. In the combined cohort, HSD3B1 (CC) genotype was associated with worse TTP (HR 1.31, 95%CI 1.02-1.67, p = 0.032) and PSA response rates (48% for CC vs 62% and 65% for AA and AC, respectively (p = 0.019, χ²)). Similar trend was observed for TTPP (HR 1.28, 95%CI 0.99-1.66, p = 0.064). OS was not different among genotypes, but was significantly shorter for patients with CC genotype in cohort 1 (HR 1.97, 95%CI 1.14-3.40, p = 0.016). There was no association between HSD3B1 genotype and time to castration-resistance in either of the two cohorts. Multivariable analysis showed that LDH, ALP, hemoglobin and use of AA or ENZA as first-line therapy for mCRPC were independent prognostic factors for TTP and TTPP; non-significant association was observed for genotype and TTP. Conclusions: HSD3B1 homozygous variant genotype (CC) was associated with shorter TTP and lower PSA response rate in mCRPC patients treated with AA or ENZA. However, the CC genotype did not provide prognostic information beyond that conferred by standard clinical variables, suggesting that it may not be a suitable stand-alone biomarker in mCRPC.

Worse Prognosis

Abstract The fusion transcript CBFB-MYH11 is the molecular correlate of inv(16)/t(16;16) and strictly associated with FAB subtype M4eo. This subgroup is associated with a favorable prognosis in AML. However, approximately 30% of the patients relapse. Our intention was to examine prognostic factors for the outcome within this subgroup. Therefore 153 CBFB-MYH11 positive AML patients were analyzed. The median age was 52 years (range 18–83), 80 patients were female, 73 were male. In 22 cases AML was therapy-related, in 131 cases a de novo AML was diagnosed. Inv(16) was detected in 138 and t(16;16) in 12 cases. In 3 cases neither inv(16) nor t(16;16) were detectable despite PCR and FISH positivity for CBFB-MYH11 suggesting cryptic rearrangements. The most frequent additional cytogenetic abnormalities were +8 (n=19), +9 (n=3), +21 (n=7), +22 (n=23). Cox regression analysis revealed that advanced age (OS: p=0.026; EFS: p=0.029) and increased CBFB-MYH11/ABL ratio at diagnosis (OS: 0.016, EFS: p=0.064) were associated with a worse prognosis. Using log rank test additional factors influencing survival were detected. These included: t(16;16) vs inv(16) (OS: n=8, censored 4, median 362 days vs n=118, censored 92, median not reached, p=0.018; EFS: n=8, censored 4, median 232 days vs n=118, censored 70, median 918 days, p=0.048) and trisomy 21 vs no additional aberrations (OS: n=6, censored 3, median 435 days vs n=74, censored 59, median not reached, p=0.024; EFS: n=6, censored 2, median 293 d vs n=74, censored 44, median 764 days, p=0.0047). Therapy related AML was associated with worse EFS than de novo AML (n=16, censored 6, median 371 days vs n=112, censored 70, median 1179 days, p=0.0167) and there was a trend towards worse OS (p=0.157 n=16, censored 10, median 764 days vs n=112, censored 88, median not reached). A multivariate analysis including t(16;16), age, CBFB-MYH11/ABL ratio, therapy related AML and +21 as covariates revealed t(16;16) and age as independent factor for OS (p=0.014 and p=0.015, respectively) and age, t(16;16), and +21 as independent factors for EFS (p=0.047, p=0.013, and p=0.016, respectively). There was no evidence that the additional aberrations +22 or +8 had an influence on survival. Taken together our data suggest that t(16;16) as compared to inv(16), trisomy 21 and age are associated with worse prognosis in patients with CBFB-MYH11 positive AML.

14062 Background: To compare surgical and non-surgical treatment approaches for anal cancer and to identify prognostic factors. Methods: Survival data of 214 patients with cancer of the anal canal were reviewed who were referred for radiotherapy to the Department of Radiation Oncology of the University of Hamburg, Germany between 1/88 and 3/05. 75 patients received a definitive radiochemotherapy (RCT) with 5-FU and MMC according to international standards, 43 an operation followed by RCT (OP+RCT), 37 an operation followed by irradiation (OP+RT), 25 an irradiation alone (RT) and 34 an operation alone because they refused a planned adjuvant RCT or RT. The operations had been performed by different referring hospitals in and around Hamburg. Results: The median follow-up time of the living patients was 67 months (1–200 months). The 10 year overall survival rate for RCT was 0.62 (95%CI 0.46–0.77), for OP+RCT 0.65 (95%CI 0.47–0.83), for OP+RT 0.55 (95%CI 0.37–0.74), for OP alone 0.51 (95%CI 0.26–0.75) and for RT alone 0.27 (95%CI 0.05–0.48). There was no statistical difference between the overall survival of patients who received RCT, OP+RCT and OP+RT according to Kaplan Meier analysis (log rank test, p = 0.71). Cox regression analysis was used to examine the simultaneous influence of the prognostic factors T, N, age, haemoglobin concentration before radiotherapy, gender, and grading on the survival of patients who were treated with RCT. The model (p = 0.015) revealed T and N to be the only statistically significant prognostic factors. Conclusions: The different surgical and non-surgical approaches to treat cancer of the anal canal in Hamburg obviously reflect the individual preferences of the different physicians. Statistical analysis did not show a benefit of an OP added to RCT. Prognostic factors for survival after RCT were the T- and N-stage. No significant financial relationships to disclose.

4128 Background: The incidence of HCC is significantly higher in males (M) than females (F). Preclinical models suggest a role for estrogen in attenuating progression of HCC by various mechanisms such Il-6 suppression or estrogen receptor α-mediated inhibition of NF-κB activity. We investigated the impact of age and gender on survival in patients with HCC using the SEER data. Methods: We identified all patients diagnosed with HCC (ICD-O-3 Site code C22.0 and Histology Code 8170-8175) from 1988 to 2009 from the SEER registry. Pts with information on gender, age, ethnic background, and staging were included in the analysis. Exclusion criteria included fibrolamellar histology, diagnosis at autopsy or by death certificate, and absence of survival data. Hazard ratios (HR) for survival were derived using Cox regression model adjusted for race, year of diagnosis, marital status, treatment, birthplace, differentiation and tumor size. Results: A total of 38,250 pts were identified; 76% males; 50% White, 12% African American, 21% Asian, 16% Hispanic, and 1% Native American. 45% had liver limited disease (44%M, 50%F), 37% had macrovascular invasion (37%M, 35%F), 18% had metastatic disease (19%M, 15%F). Treatment information was available for pts diagnosed after 1998 (n=32,938): 11% received liver directed therapy, 11% had surgical resection, and 7% underwent liver transplantation. Median age at diagnosis was 61 years for M versus 68 years for F. HR for OS of F versus M was 0.83 (95%CI:0.78-0.89) for pts < 55 years old. In contrast, the OS HR of F versus M was 0.95 (95%CI:0.92-0.98) for pts ≥ 55 years old and 0.98 (95%CI: 0.94-1.01) for pts ≥ 65 years old. The F vs. M (<55 yrs old) HR for OS by stage of disease was: liver limited disease: HR 0.90, CI: 0.81-1.01; macrovascular invasion: HR 0.81, CI: 0.73-0.89; metastatic disease, HR 0.80, CI: 0.70-0.92. Conclusions: Females under the age of 55 appear to have superior survival compared to males with HCC based on a SEER data analysis. This finding is in line with preclinical reports of estrogen attenuation of HCC development and progression.

Pik3ca Mutations

386 Background: Recent data has demonstrated that regular ASA use improves overall and cancer-specific survival in the subset of CRC patients harboring PIK3CA mutations. However, as this series only analyzed 15 PIK3CA mutant CRC patients with metastatic disease at diagnosis, it remains uncertain whether the survival benefit associated with regular ASA use extends to patients with metastatic disease. We combined data from two large academic institutions to explore the association between regular ASA use and survival in metastatic CRC. Methods: Patients with PIK3CA mutated CRC were identified at Moffitt Cancer Center (MCC) in Tampa, FL and Royal Melbourne Hospital (RMH) in Australia. Prospective clinicopathological data (including age, sex, site of disease) and survival data were available. At MCC, PIK3CA mutations were identified by exome sequencing using an Illumina Next Generation Sequencing platform with 50-100X coverage. At RMH, Sanger sequencing was used to identify PIK3CA mutations. Survival analyses were conducted using Cox regression. Results: We identified 187 CRC patients who harbored a PIK3CA mutation. Median age was 72 years and median follow up was 48 months. 49 (26%) patients used ASA regularly. 47 (25%) patients had metastatic disease at diagnosis. In univariate analyses, regular ASA use was not associated with improved overall survival (HR 0.87, p = 0.60), although there was a trend towards improved cancer-specific survival (HR 0.48, p = 0.06). In patients with stage-II or stage-III disease, regular ASA use did not improve overall, cancer-specific or recurrence-free survival. However, in stage-IV patients, regular ASA use was significantly associated with improved overall (HR 0.35, p = 0.04) and cancer-specific (HR 0.28, p = 0.02) survival in a univariate analysis. Conclusions: Our study demonstrates that in patients with metastatic CRC harboring a PIK3CA mutation, regular ASA use is associated with a significant overall and cancer-specific survival advantage. However, we were not able to confirm the survival advantage across all stages. To our knowledge, our study is the largest to examine ASA use in PIK3CA mutated CRC.

280 Background: The optimal management of the primary tumour in pts with M1 at diagnosis PCa is not established. We aimed to evaluate the impact on OS of LRT (surgery or radiotherapy to the primary tumour) in de novo metastatic disease. Methods: PCa pts with M1 disease at diagnosis treated at the Royal Marsden between June 2003 and December 2011 were evaluated. LRT+ patients were defined as those that had received surgery or radiotherapy for the primary. Covariates analysed included age, diagnostic Gleason score, lines of CRPC treatment, PSA, burden of bone metastases ( ≥ 4 vs < 4 bone metastases) and ECOG PS. Kaplan-Meier analyses generated OS data. The association between LRT and OS was evaluated in univariate (UV) and multivariate (MV) Cox regression models. Results: Overall 234 pts with M1 at diagnosis were identified; 27 (11.53%) received LRT (25 XRT; 2 prostatectomy). Median time interval between diagnosis and LRT was 782 days (range 0-4130). Patients receiving LRT were younger (49 vs 61 yrs, p = 0.042), had lower baseline PSA values (68 vs 148; p < 0.001), and were more likely to have lymph node only disease (26% vs 10%; p = 0.029) and a lower burden of bone metastases with < 4 metastases (85% vs 34%;p < 0.001). Patients receiving LRT had a significantly longer survival (74.2 vs 55.1 months; HR 0.39; p < 0.001) in UV and MV cox-regression analysis (table). LRT+ remained highly prognostic, independently of disease volume at diagnosis and baseline PSA. Conclusions: LRT was associated with increased survival in patients with de novo metastatic disease, and in these analyses the prognostic utility of this LRT prognostic biomarker was independent of volume of metastatic disease at baseline and I'd baseline PSA. Other possible confounder factors may need to be taken into account when interpreting these results which require prospective validation from clinical trials such as STAMPEDE . [Table: see text]
