Abstract CONTEXT Chronic Lymphocytic Leukemia (CLL) is a clonal proliferation of small mature B-cell lymphocytes diagnosed clinically when the peripheral blood clonal B lymphocyte count is persistently >5,000/mcL with distinctive immunological markers defined by co-expression of CD5 and CD23 with additional expression of CD19, CD20 (weak) with weak surface immunoglobulin expression, usually IgM heavy chain. Expression of CD79b and FMC7 is typically negative to weakly positive. With the recent advancement in cancer genetics and the continued understanding of the transforming events in CLL, the importance of the various somatic genomic aberrations has been well documented. Multiple studies have shown the clinical implications of these aberrations in terms of their prognostic and predictive relevance in clinical practice and these genomic aberrations are usually assessed clinically by cytogenetic analysis and FISH. OBJECTIVE We proposed this study to determine the incidence of the genomic aberrations in the CLL patients diagnosed at the Rose Cancer Treatment Center of the William Beaumont Hospital between 2010 and 2015 and to determine their impact on survival among the patients diagnosed during the study period. STUDY DESIGN A retrospective review of all the patients diagnosed with CLL between 2010 and 2015 at the Rose Cancer Treatment Center was conducted with the assistance of the staff in the William Beaumont cancer registry office. We determined the demographic variables and analyzed the incidence of CLL among the subjects diagnosed within the study period. Data analysis was performed using SPSS 21 and Kaplan-Meier curves were plotted for survival analysis and log rank (Mantel-Cox) was used to compare these curves. 12-Month and 36-Month overall survival rates were analyzed by actuarial method. The distribution of the various genomic aberrations was determined using descriptive statistical analysis. RESULTS A total of 151 patients were identified at the Rose Cancer Center of the William Beaumont Hospital during the study period. The median age at diagnosis was 74 years (range 38-101) of which 90 were male (59.6%) and 61 female (40.4%). One-hundred and twenty-four (82.1%) patients were white, six patients (4.0%) were African American, two patients (1.3%) were Asian and nineteen (12.6%) patients declined to identify their race. Analysis of cytogenetic distribution showed that, twenty patients (13.2%) had normal cytogenetic, eleven patients (7.3%) had del(13q) alone, eight (5.3%) had both del(13q) and del(11q), four patients (2.6%) had del(13q) plus trisomy 12 aberrations, ten (6.6%) patients had del(13q) and other karyotypes (TP53, RB1, trisomy 1q, del(6q23), unmutated IGHV). Thirteen patients (8.6%) had trisomy 12 abnormality, five patients (3.3%) had del(11q), three patients (2.0%) had del(17p), twenty-five patients (16.6%) had complex cytogenetic abnormalities and fifty-two (34.4%) patients cytogenetic were not checked (see Fig.1). The median follow-up duration for the cohort was 22.5 months (range 0 to 70 months). The survival rates at 12 months and 36 months for the cohorts based on cytogenetic are described in table 1 and fig.2. CONCLUSION Our study showed that majority of our patients (34.4%) did not have their cytogenetics checked at diagnosis, patients with del(13q) abnormality alone had the most favorable 36-Month overall survival rate and those with del(17p) fared worst with the most unfavorable outcome followed by patients with complex cytogenetic abnormalities. Presence of del(13q) with either del(11q) or trisomy 12 abnormalities appeared to ameliorate their poor and intermediate adverse prognostic effects, respectively. Figure 2 Figure 2.

Background:We report survival and pretreatment prognostic factors for survival and chemosensitivity in 53 oligodendrogliomas treated with PCV (procarbazine, lomustine and vincristine) chemotherapy.Methods:A total of 53 patients with histologically proven oligodendroglioma, anaplastic oligodendroglioma or oligo-astrocytoma and treated with PCVwere extracted from the London Regional Cancer Center database. A retrospective review was conducted to evaluate overall survival and pretreatment prognostic factors for survival and chemosensitivity.Results:The median survival time from diagnosis was 123.6 months. The overall five- and ten-year survival rates were 72.7% and 52.7% respectively. Age <40, seizure as an initial symptom, absence of cognitive deficit and presence of a homogeneous hypodense lesion without contrast enhancement on the initial pretreatment CT scan were all factors independently associated with favorable outcome. The presence of increased cellularity, pleomorphism, mitosis, vascular proliferation and grading as an anaplastic lesion using these surrogates on pathological assessment, were all associated with an unfavorable outcome in univariable analysis. In multivariable analysis, only the anaplastic grading and presence of increased cellularity were significant determinants of unfavorable survival. The only factor adversely associated with chemosensitivity was the presence of a focal symptom at presentation.Conclusion:Overall survival is significantly longer in oligodendroglial lesions than in fibrillary astrocytic tumors. A two tier grading system using standard morphological features seems accurate in predicting outcome in these patients. The presence of a neoplastic astrocytic component does not seem to impact the outcome. No clinical, radiological or pathological factor could be identified to reliably predict chemotherapy response.

Abstract In 1980, the French Cooperative Group on Chronic Lymphocytic Leukemia started a randomized clinical trial in which intermediate prognosis patients (stage B) received either an indefinite course of chlorambucil (0.1 mg/kg/d) or 12 cycles of the COP regimen (vincristine, cyclophosphamide, and prednisone). We present the results of the third interim analysis based on 291 patients (151 in the chlorambucil group and 140 in the COP group) with a mean follow-up of 53 months at the reference date of June 1, 1987. At this date, 129 deaths were observed, 65 in the chlorambucil group and 64 in the COP group; there was no improvement in overall survival with the COP regimen (P = .44) even after adjusting for both prognostic and imbalanced factors (P = .24). The 3-year and 5-year overall survival rates were, respectively, 69% and 44% in the chlorambucil group as compared with 73% and 43% in the COP group. The median survival times were 58 months in the chlorambucil group and 57 months in the COP group. Moreover, no significant difference was observed between the two treatment groups in terms of either treatment response, 9-month status, time to disease progression to stage C, or causes of death.

Abstract Abstract 4604 Background: Chronic lymphocytic leukemia (CLL) has the highest incidence and prevalence of any leukemia in the United States. It has a characteristic immunophenotype, but variant forms (typically termed “atypical CLL”) are commonly encountered. It is not known if this immunophenotypic heterogeneity in CLL is clinically relevant. We hypothesized that the immunophenotype of CLL cells correlates with both biologic parameters and clinical outcomes. Methods: We performed a retrospective review of clinical, biologic, and flow cytometric data of patients undergoing an evaluation of an absolute lymphocytosis at the Duke University and Durham VA Medical Centers. Patients meeting immunophenotypic criteria for CLL based on cell surface expression of CD5, CD19, CD20, CD23, and surface immunoglobulin light chain (sIg) were included in this analysis. Atypical CLL was defined if any of the following were observed: (1) expression of CD5, CD20, CD23, or sIg that differed from a typical CLL immunophenotype (e.g. bright CD20 or low CD23; hereafter non-standard immunophenotype), (2) expression of T cell markers CD7 or CD8, or (3) expression of CD123. Through electronic chart review, clinical and biologic parameters were abstracted. These included age; gender; ethnicity; WBC, hemoglobin, platelet count, and Rai stage at diagnosis; time to first treatment; overall survival; CD38, ZAP70, IGHV mutation status, and interphase cytogenetics (FISH). A chi square test or Fisher’s exact test for small sample sizes was used to test association of categorical data. The central tendencies of continuous measurement were compared using the Wilcoxon rank sum test. Overall survival and time to treatment were calculated using the Kaplan-Meier product limit method. Survival curves were compared using the log-rank test. This study was approved by IRBs at Duke University and Durham VA Medical Centers. Results: We reviewed 189 patients, including 119 (63%) with typical CLL immunophenotype and 70 (37%) with atypical. Among patients with atypical CLL, 93% (65 of 70) had a non-standard immunophenotype, 33% (23 of 70) had expression of T cell markers, and 33% (14 of 43) had expression of CD123. We observed expression of T cell markers in 12% (23 of 189) and CD123 in 12% (14 of 114) of the entire cohort, respectively. At the time of diagnosis, there was no association between typical or atypical CLL immunophenotype and age, gender, race/ethnicity, WBC, hemoglobin, platelet count, or Rai stage (p>0.05 for all comparisons). With regard to biologic parameters, there was no association of CLL immunophenotype with the proportion of patients with CD38 ≥30%; however, the central tendency of CD38 was higher in the atypical group when analyzed as a continuous variable (median value 38% vs. 10%, p=0.04). There was no difference in the proportion of ZAP70 positive cases between typical and atypical groups. Analysis of interphase cytogenetics (FISH) data showed that a higher percentage of typical than atypical immunophenotypes had del 13q as a sole abnormality and a lower percentage had trisomy 12 (p=0.02). Despite the increased frequency of del 13q as a sole abnormality, lower frequency of trisomy 12, and lower expression of CD38, there was no difference between groups in time to first treatment (median 5.3 years for typical vs. 2.1 years for atypical; p= 0.11) or in overall survival (median 13.6 yrs64 years for typical vs. 18.0 years for atypical; p=0.11) (Figure 1). However, when patients with non-standard CLL immunophenotype were compared to those with a standard immunophenotype, a significantly shorter time to first treatment was observed (median 6.0 years for standard immunophenotype vs. 2.2 years for non-standard, p=0.03). Conclusion: Different immunophenotypic subtypes are commonly encountered in the care of patients with CLL. These groups have different biological characteristics, including differences in expression of CD38 and cytogenetic abnormalities. Exploratory analysis also showed differences in clinical outcomes based on immunophenotypic parameters. Validation studies are currently underway.

Abstract 4241 Background: Acute lymphocytic leukemia (ALL) incidence is approximately 4000 cases per year in the USA. Several standard induction regimens are used upfront for the treatment of ALL. The HyperCVAD regimen is currently a widely used upfront treatment option for adult ALL patients based on pioneer work at MD Anderson Cancer Center (MDACC). Here we present our experience with the HyperCVAD regimen treating ALL at Moffitt Cancer Center (MCC), representing the largest cohort treated with this regimen outside MDACC. Methods: Patients who were diagnosed and treated at MCC with ALL were identified through the MCC Total Cancer Care database. Individual charts were reviewed. All patients treated with the HyperCVAD regimen frontline were included in this analysis. The HyperCVAD regimen was administered as originally described at MDACC. Philadelphia positive patients were treated with addition of tyrosine kinase inhibitors (TKI) (imatinib or dasatinib). Descriptive data are reported, t-test was used to compare continuous variables, chi square test for categorical variables, Kaplan Meier curves were used for overall survival (OS). Log rank test was used to compare survival times between groups. Cox regression analysis was used for multivariable analysis. All analyses were conducted using SPSS version 19.0 Results: Between 1/1/2002 and 6/30/2011, 100 ALL patients were treated with HyperCVAD at MCC. The median age was 45 years (range 18–83), 26 were above age of 60 years and 26 were below age of 30 years. Sixty three percent were male and 37% were female. Sixty five percent were white, 6% were African America, 7% were Hispanic and 22% were described as other. B-Cell ALL accounted for 83% of patients, while the other 17% had T-Cell origin. Of the 100 patients, 23% of patients were Philadelphia chromosome positive, while 72% were negative, and in 5% karyotype was unknown. Splenomegaly was present at diagnosis in 18% of patients, while 17% presented with lymphadenopathy. Twenty-three percent of patients presented with a WBC of 50,000 or greater. CNS disease was noted in 9% of patients at diagnosis. Seventy-six percent achieved a complete response (CR), while 12% had refractory disease. Response to frontline was not documented in 12% of patients. The median overall survival was 27 months (95% CI 15.6–38.3). In univariable analysis, no difference in outcome was observed based on gender, race, Philadelphia chromosome positivity, B or T-cell origin, presence of lymphadenopathy, splenomegaly, WBC >50,000 or CNS disease at presentation. Age was a significant prognostic factor. The median OS for patients <60 years old was 34 months (95% CI 20.8–47.), and 16 months for patients >60 years old (95% CI 6.9–25.1) (p= 0.006) (figure-1) The median OS was higher in patients who achieved CR with frontline chemotherapy. OS was 34 months (95% CI 22.5–45.4) compared to 13 months in patients who did not achieve CR after frontline (95% CI 7.3–18.7) (p=< 0.005). Thirty-eight patients proceeded to allogeneic SCT. The median OS was 40 months in patients who proceeded to allogeneic SCT compared with 16 months in patients who did not (p=0.002). In Cox regression analysis, achieving CR with frontline induction, and allogeneic SCT were statistically significant independent variables for OS for adult patients with ALL. The odds ratio was 3.4 in patients achieving CR with frontline therapy, and 3.1 in patients who underwent allogeneic SCT. Conclusion: To our knowledge, this cohort represents the largest group of ALL patients treated outside MDACC with HyperCVAD based regimens, with similar overall results in the setting of tertiary centers. Achievement of CR after frontline therapy, and undergoing allogeneic SCT were statistically significant prognostic indicators. The outcome of elderly patients (age >60) was inferior. In the elderly population there were lower rates of CR and less number of patients proceeded to allogeneic SCT. The outcome in Philadelphia chromosome positive ALL has improved with the introduction of TKI’s and allogeneic SCT. Disclosures: No relevant conflicts of interest to declare.

Abstract Introduction: Incidence of secondary malignant neoplasm in patients with chronic lymphocytic leukemia (CLL) is already established. Genetic predisposition has been considered to be a possible contributory factor for the preponderance of second cancers in this population. In the present study, we examined the frequency, characteristics, and clinical outcomes of secondary malignancies in patients with CLL based on their Interphase fluorescence in situ hybridization (FISH) panel. Methods: We reviewed the medical records of consecutive patients with CLL observed or treated at Ellis Fischel Cancer Center during the period from 2007-2014. We collected demographic data, CLL Rai stage, treatment history, Interphase fluorescence in situ hybridization (FISH) panel results and the presence of a secondary malignancy (skin cancers, solid tumors and hematologic malignancy excluding CLL transformation).Our aim was to investigate the association between secondary malignancy and chromosomal abnormalities and other risk factors using Chi2test for categorical variables and Wilcoxon rank-sum test for continuous variables. Cox proportional hazard models and logistic regression models were used to evaluate risk factors of developing secondary malignancy and overall survival. Results: We identified 142 CLL patients who were either observed (n=62) or had a history of treatment (n=80) for CLL. 67% were male and 33% were female. 85% of patients were Caucasians, 10% African Americans, and 5% other. Familial CLL was present in 6% of cases. 51% of patients were non-smokers. 5% of patients had cancers preceding the diagnosis of CLL (non-melanoma skin cancers=3, melanoma=1, Hodgkin's lymphoma=1, Prostate=2). 28% of patients developed secondary malignancies after the diagnosis of CLL; among them non-melanoma skin cancers were the most common (78%), followed by cutaneous melanoma (9.5%) and papillary thyroid cancer (4.7%). Other malignancies included lung (2.3%), kidney (2.3%), prostate (2.3%) and ocular melanoma (2.3%). 12% patients had aggressive non-melanoma recurrent skin cancers that require multiple treatments along-with systemic therapy for progressive CLL. CLL-FISH panel at diagnosis was available in 98 patients. Among these patients,13q deletion was present in 45%. Within the 13q deletion group, secondary malignancy was noted in 50% during a median follow up of 7 years. All cases of papillary thyroid cancers were also present in 13q deletion. In contrast, 11q deletion was detected in 15% and trisomy 12 in 18% of patients with incidence of secondary malignancy 40% and 10%, respectively. No solid malignancy other than skin was identified in the 11q deletion and trisomy 12 groups. 17p deletion was present in 5% of cases and 60% of 17p deletion cases had secondary cancers (skin 80%). Normal FISH panel was present in 17% cases and 20% of normal FISH had secondary malignancy (solid 10%, skin 10%). The median overall survival time is 6 years for the entire cohort (IRQ: 3-9 years). Secondary malignancy was associated with worse overall survival (OS) (HR=0.57, 95% CI:0.33-0.98, p=0.04) compare to patients who did not have secondary malignancy. The risk of secondary malignancy is increased in patients with advanced age (OR=1.05, 95% CI:1.00-1.10, p=0.04) and in those who were treated with alkylating agent for CLL OR=6.62, 95% CI:2.08-21.03, p=0.001. However, there were no significant difference on risk of developing secondary malignancy based on specific chromosomal FISH result, Rai stage, smoking, family history and gender. Conclusion: Secondary malignancies are frequent in patients with detectable chromosome abnormality on FISH panel. However, the increased risk of secondary malignancy does not correlate with specific cytogenetic abnormality. Non melanoma skin cancers are exceedingly common in CLL patients and carries aggressive couse in progressive CLL patients. Larger studies are required to identify subtype of CLL based on integrated mutational and cytogenetic subgroup that are at increased risk of specific secondary malignancies.

e18128 Background: PDAC has a rising incidence and relatively static mortality rates. Current cytotoxic regimens confer median survivals of 8.5- 11 months (Von Hoff, Conroy, et al. NEJM 2013, 2011). National Cancer Institute-designated Comprehensive Cancer Centers potentially allow greater access to multidisciplinary consultation for complex cancer care. Although the widespread benefits of NCICCCs are acknowledged, there is limited data demonstrating superior outcomes for patients treated at these centers. Methods: Patients with stage IV PDAC, diagnosed between 01/01/13 and 12/31/14, were identified and followed until death or 12/31/2016. These patients had care centralized to MSKCC and the analysis was conducted to evaluate key patient (pt) and disease characteristics, systemic therapies and outcomes.Survival times were calculated from the date of diagnosis. Results: N=391 pts identified, 210 males (54%), 181 females (46%). Median age 66 years (range 27-91). Table 1 outlines key points. For entire cohort, median overall survival (mOS): 11.4 + 9 months, 1-year (yr) and 2-yr survival rates (SR) of 48% and 15.1% respectively. N= 165 (42%) received mFOLFIRINOX-based regimen as 1st-line therapy with mOS 13.2 + 8.9 months, 1-yr and 2-yr SR of 59.4.% and 20% respectively. N= 118 (30.1%) received gemcitabine + nab-paclitaxel- based regimen as 1st line therapy had a mOS of 11.6 + 9 months with 1-yr and 2-yr SR of 49.1% and 16.2% respectively. Conclusions: At MSKCC, a major referral center for PDAC, outcomes for stage IV disease compare favorably to contemporary trial outcomes with notable 2-yr survivorship (long-term survival analysis of MPACT trial showed 1-yr and 2-yr SR of 35% and 10% respectively). Contributing factors likely reflect multidisciplinary expertize, patient selection and biases. Centralized care for complex illnesses may improve outcomes. [Table: see text]

In 1980, the French Cooperative Group on Chronic Lymphocytic Leukemia started a randomized clinical trial in which intermediate prognosis patients (stage B) received either an indefinite course of chlorambucil (0.1 mg/kg/d) or 12 cycles of the COP regimen (vincristine, cyclophosphamide, and prednisone). We present the results of the third interim analysis based on 291 patients (151 in the chlorambucil group and 140 in the COP group) with a mean follow-up of 53 months at the reference date of June 1, 1987. At this date, 129 deaths were observed, 65 in the chlorambucil group and 64 in the COP group; there was no improvement in overall survival with the COP regimen (P = .44) even after adjusting for both prognostic and imbalanced factors (P = .24). The 3-year and 5-year overall survival rates were, respectively, 69% and 44% in the chlorambucil group as compared with 73% and 43% in the COP group. The median survival times were 58 months in the chlorambucil group and 57 months in the COP group. Moreover, no significant difference was observed between the two treatment groups in terms of either treatment response, 9-month status, time to disease progression to stage C, or causes of death.

Abstract The clinical course for patients with chronic lymphocytic leukemia is extremely heterogeneous. The Rai and Binet staging systems have been used to risk-stratify patients; most patients present with early-stage disease. We evaluated a group of previously untreated patients with chronic lymphocytic leukemia (CLL) at initial presentation to University of Texas M. D. Anderson Cancer Center to identify independent characteristics that predict for overall survival. Clinical and routine laboratory characteristics for 1674 previously untreated patients who presented for evaluation of CLL from 1981 to 2004 were included. Univariate and multivariate analyses identified several patient characteristics at presentation that predicted for overall survival in previously untreated patients with CLL. A multivariate Cox proportional hazards model was developed, including the following independent characteristics: age, β-2 microglobulin, absolute lymphocyte count, sex, Rai stage, and number of involved lymph node groups. Inclusion of patients from a single institution and the proportion of patients younger than 65 years may limit this model. A weighted prognostic model, or nomogram, predictive for overall survival was constructed using these 6 characteristics for 5- and 10-year survival probability and estimated median survival time. This prognostic model may help patients and clinicians in clinical decision making as well as in clinical research and clinical trial design.

232 Background: The incidence of VTE is relatively high among mPC pts, upto 57%. It is associated with higher health care burden and mortality. We evaluated the mPC pts treated at a single academic center from 2010-16 for prevalence of VTE, its impact on survival and possible risk factors. Methods: Medical charts of mPC pts treated at a single academic center were analyzed retrospectively for VTE diagnosis, overall survival and potential risk factors for VTE development. The factors considered were: age, sex, stage, body mass index, smoking status, surgery, performance status (PS), Charlson comorbidity index (CCI) and treatment. Logistic regression was used to identify the factors correlating with VTE and Cox Proportional Hazard model was used to evaluate overall survival (OS) differences between those with VTE (Gp A) and those without VTE (Gp B). Results: Out of the 439 mPC pts (52% males, 86% with PS0-1, 63% with stage IV at diagnosis), 127 (29%) were in Gp A and 312 (71%) in Gp B. The groups were well balanced with respect to all factors except age (median age 67 Gp A; 65 in Gp B, p = 0.04). 2.3 % of pts in Gp A and 4.8 % pts in Gp B were on anticoagulation for reason other than VTE treatment. Within Gp A, 55% developed VTE after diagnosis of metastasis. A clear separation of the survival curves noted beyond the median OS (9 m, P = 0.02), favoring GpB. Statistically significant factors associated with risk of VTE included advanced stage at diagnosis (P = 0.004) and worse PS (P = 0.005). Treatment regimen used and CCI didn’t correlate with the risk of development of VTE. Conclusions: The incidence rate of VTE in our patients is lower than published literature, yet the diagnosis of VTE was associated with worse OS. Most cases occurred after the diagnosis of metastatic disease. The higher use of anticoagulants for other medical causes may be contributing to a lower incidence of VTE in mPC. These findings need prospective Validation.
