Abstract Background: CR and CR with incomplete count recovery (CRi) are associated with prolonged overall survival (OS) for acute myeloid leukemia (AML) patients (pts) treated with curative-intent, induction therapy. For AML pts treated with azacitidine (AZA), response (CR, partial response, marrow CR, or hematologic improvement) is also associated with prolonged OS. We evaluate whether patients given AZA for myelodysplastic syndromes (MDS) or AML had longer OS if they achieved CR. We also compare the effect size of CR on OS between AZA regimens and 7+3. Patients and Methods: We analyzed four SWOG studies: S1117 (n=277) was a randomized Phase II study comparing AZA to AZA+lenalidomide or AZA+vorinostat for higher-risk MDS and CMML pts (median age 70 years, range 28-93); S0703 (n=133) treated AML pts not eligible for curative-intent therapy with AZA+mylotarg (median age 73 years, range 60-88). We analyzed the 7+3 arms of S0106 (n=301 were randomized to 7+3, median age 48 years, range 18-60) and S1203 (n=261 were randomized to 7+3, median age 48 years, range 19-60). CR was defined per 2003 International Working Group criteria. In S1117 CR was assessed every 16 weeks and patients remained on therapy until disease progression. In S0703, S0106, and S1203 CR was assessed following 1-2 induction cycles; patients not achieving CR (S0106) or CRi (S0703 and S1203) were removed from protocol treatment. OS was measured from date of study registration. To avoid survival by response bias, we performed landmark analyses of OS. We present results based on the study-specific landmark date that 75% of pts who eventually achieved a CR had done so (S1117 144 days, S0703 42 days, S0106 44 days, S1203 34 days). Pts who did not achieve CR by this date were analyzed with pts who never achieved CR. Pts who died or were lost to follow-up before this date were excluded from analyses. As a sensitivity analysis we also analyzed based on the 90% date; results were not materially different. Log-rank tests were used to compare survival curves and Cox regression models were used for multivariable modeling including baseline prognostic factors age, sex, performance status, white blood cell count, platelet count, marrow blast percentage, de novo disease (versus antecedent MDS or therapy-related disease), study arm (for S1117 only), and cytogenetic risk (IPSS criteria for S1117, SWOG criteria for S0703, S0106, and S1203). The following analysis considers morphologic CR only. S0106 treated CR with incomplete count recover (CRi) pts as treatment failures (S0703 and S1203 did not) and CRi was not defined for S1117. Hematologic improvement was only defined for S1117 patients. Results: In univariate analysis, CR was significantly associated with prolonged survival among MDS pts treated with azactidine on S1117 (HR=0.55, p=0.017), confirming the results seen in AML pts treated with azacitidine (and mylotarg, S0703, HR=0.60, p=0.054) and 7+3 (S0106 HR=0.44, p<0.001; S1203 HR=0.32, p<0.0001) (Figure 1). For each study this relationship remained significant in multivariable analysis controlling for baseline prognostic factors (S1117 HR=0.25, p<0.001; S0703 HR=0.64, p=0.049; S0106 HR=0.45, p<0.001; S1203 HR=0.41, p<0.001). There was no evidence that the impact of CR varied across the four cohorts (interaction p-value = 0.76). In the full cohort, the effect of CR was associated with a HR of 0.45 (Table 1). Conclusion: Adjusting for pt characteristics, achievement of morphologic CR was associated with a 60% improvement in OS, on average, compared to that seen in pts who don't achieve a CR, regardless of whether pts were treated with 7+3 or AZA containing regimens, and suggesting that value CR is similar of whether pts receive more or less "intensive" therapy for these high grade neoplasms.

Abstract Introduction: Red blood cell distribution width (RDW) has emerged as a potential prognostic factor in solid tumors and lymphomas. Previous studies have shown an association between increased levels of RDW and inflammatory diseases, being a surrogate marker of inflammation and a predictor of poor outcome. Data on the impact of RDW in outcomes of patients with aggressive peripheral T-cell lymphoma (PTCL) are scarce. Methods: We performed a retrospective study on consecutive patients with a de novo diagnosis of aggressive PTCL diagnosed and treated at our institution between 2010 to 2016. All patients included were treated with chemotherapy with a curative intent. The RDW was collected from the hemogram of PTCL patients at diagnosis. RDW-CV >14% and RDW-SD >49 fL were our cut-offs for the categorical analysis. We fitted univariate and multivariate Cox proportional hazard regression models for overall survival (OS). P<0.05 were considered statistically significant. Results: A total of 101 patients with de novo aggressive PTCL were included. This study included 53 patients (52%) with PTCL, not otherwise specified, 16 patients (16%) with extranodal natural killer/T-cell lymphoma,15 (15%) with adult T-cell lymphoma/leukemia,14 patients (14%) with anaplastic large cell lymphoma, 2 patients (2%) with angioimmunoblastic T-cell lymphoma, and 1 patient (1%) with enteropathy-associated T-cell lymphoma. Median age was 57 with a male predominance (69%). Clinically, 45 patients (45%) were 60 years or older, 41 patients (34%) had ECOG ≥2, 63 patients (65%) had increased LDH levels, 68 patients (67%) had > 1 extranodal site, 65 patients (64%) had stage III/IV disease, and 55 patients (54%) had B symptoms. RDW-CV was >14% in 64 patients (64%). RDW-SD was >49 fL in 35 patients (35%). 38% of patients received CHOEP, 29% received CHOP, and 33% received other regimens. The overall response rate was 68%; 50% had a complete response and 18% had a partial response. At 5 years, median overall survival (OS) was 46%. In the univariate Cox regression analysis, ECOG ≥2 (p<0.001), high RDW-CV >14% (p<0.001), high RDW-SD >49 fL (p=0.007) and high neutrophil-lymphocyte ratio (NLR >4) (p=0.002) were associated with a worse survival. In the multivariate Cox regression analyses, ECOG ≥2 (HR 3.1 CI 1.6-6.0; p=0.001) and high RDW-CV >14% (HR 2.7, 95% CI 1.2-6.0; p=0.01) were independent predictors of poor survival. RDW-CV was an independent factor of survival when was compared with IPI and NCCN-IPI score. Conclusions: RDW is an independent marker for adverse prognosis in aggressive patients with aggressive PTCL treated with curative intent. Figure. Figure.

Methylating Agents

Abstract INTRODUCTION: The management of myelodysplastic syndrome/myeloproliferative overlap neoplasms (MDS/MPN) remains challenging due to their molecular complexity. Hypo-methylating agents (HMA) have been used for cytoreduction and preparation of patients for allogeneic blood or marrow transplantation (BMT). However, less than 50% patients have a meaningful response to HMA and predictive factors for response remain unknown. The aim of our study is to examine molecular predictors of response to HMA in patients with MDS/MPN. PATIENTS AND METHODS: We performed a retrospective analysis of 150 patients evaluated at our center for chronic myelomonocytic leukemia (CMML), atypical chronic myeloid leukemia (aCML) and unclassifiable MDS/MPN (MDS/MPN-U) between 1/1/2010 and 12/31/2020. Forty-three individuals who were treated with HMA during chronic phase and had next generation sequencing (NGS) using the established 63-genes panel were identified. Complete and partial remission (CR and PR), and marrow response (MR) were assessed based on the MDS/MPN International Working Group response criteria. Univariate logistic regression analysis was used to associate the number of somatic mutations or high-risk (HR) mutations (NRAS, SETBP1, RUNX1, EZH2, TP53, ASXL1, STAG2), and other disease specific factors at the time of the initiation of HMA with response categories. Multivariable analysis for modeling response were conducted via Least Absolute Shrinkage and Selection Operator (LASSO) logistic regression approach, where the predictors were selected based on 5-fold cross validation with turning parameter selected to minimize deviance of logistic regression model. Kaplan-Meier was used to assess the overall survival based on the CR/PR status at 6 months from the initiation of HMA in landmark analysis. Cox-regression analysis considering the occurrence of CR/PR as a time-varying covariate was used to assess the impact of CR/PR on overall survival. RESULTS: Fifteen women and 28 men with a median age 67 years (range: 45 - 85 years) and a median follow up of 1.5 years (range: 91 days - 5.2 years) were included. Twenty five (58.1%) had CMML, 15 (34.9%) had MDS/MPN-U and 3 (7%) had aCML. Thirty-four patients (79.1%) received azacitidine (median number of cycles: 4.5, range: 1 - 65) and 9 patients (20.9%) received decitabine (median number of cycles: 4, range: 3 - 21). Seventeen patients (39.5%) underwent BMT following HMA therapy. The incidence of AML transformation was 16%. No patients had CR while 56% achieved a PR and 42% had an MR. Univariate analysis showed that ≥2 HR mutations (OR 0.19, 95% CI 0.05-0.67), SETBP1 mutation (OR 0.16, 95% CI 0.02-0.76), RUNX1 mutation (OR 0.1, 95% CI 0.01-0.48) and a mutation in at least one out of the SETBP1, RUNX1 and EZH2 genes (OR 0.05, 95% CI 0.01-0.21) were associated with absence of PR. ≥2 HR mutations (OR 0.23, 95% CI 0.05-0.9), and the presence of a mutation in one out of the SETBP1, RUNX1 and EZH2 genes (OR 0.16, 95% CI 0.03-0.62) were associated with absence of MR on univariate analysis. Finally, older age as a continuous variable was associated with PR (OR 1.09, 95% CI 1.01-1.19) and MR (OR 1.12, 95% CI 1.03-1.24). Presence of a mutation in one of the SETBP1, RUNX1 and EZH2 genes with age adjusted was selected from LASSO approach and significantly predicted the absence of PR (OR 0.05, 95% CI 0.01-0.27), and MR (OR 0.19, 95% CI 0.04-0.91) (Table 1). Using the landmark of 6 months after the initiation of treatment, Kaplan-Meier analysis showed that PR at 6 months was associated with superior overall survival (P=0.010) compared to patients with no response (Figure 1). Similarly, Cox-regression analysis revealed that the occurrence of PR following the initiation of treatment was associated with better overall survival (HR 0.26, 95% CI 0.9-0.13, P=0.010). CONCLUSIONS: Mutations in SETBP1, RUNX1 or EZH2 genes predicted absence of response to HMA among patients with MDS/MPN independent of other factors including karyotype, blast percentage and R-IPSS. These findings suggest that the molecular profile of MDS/MPN patients can potentially identify patients with HMA-refractory phenotype. Multi-institutional studies of larger cohorts are required to verify these results and develop novel treatment strategies especially for patients with high-risk mutations in MDS/MPN. Figure 1.

Abstract Abstract 4866 Background Multiple myeloma (MM) is an incurable malignant disease, characterized by increased angiogenesis in the bone marrow (BM) microenvironment and aberrant BM metabolism. Matrix metalloproteinases (MMP) are a family of zinc-dependent endopeptidases implicated in tumour progression, invasion, metastasis and angiogenesis, via proteolytic degradation of extracellular matrix. MMPs are inhibited by tissue inhibitors of metalloproteinase (TIMP). Although recent studies have implicated MMP 9 in MM bone disease, little is known about the role of the TIMPs. Objectives a) to compare levels of sRANKL, OPG, MMP-2, MMP-9, TIMP-1, TIMP-2, VEGF, bFGF, microvessel density (MVD) between newly diagnosed MM patients and healthy controls; b) to determine the association of these molecules with disease progression, bone disease and neoangiogenesis and c) to evaluate the impact of these variables on survival. Patients and Methods As of July 2009 38 newly diagnosed and untreated multiple myeloma patients were enrolled in the study. The median age was 61years-old (range 39-91) with 24 (63%) males. Patients were diagnosed and categorized according The International Myeloma Working Group criteria and ISS, respectively. Bone involvement was graded according to standard X-ray: patients with no lesions, or with one/ two bones involved or diffuse osteoporosis were classified as low score, whereas patients with lesions in more than two bones or presence of bone fracture were classified as high score. MMP-2 and MMP-9 were determined by PAGE gelatin zymography from plasma as previously described. MMP-9, TIMP-1 and TIMP-2, OPG and sRANKL concentrations were measured by ELISA. The levels of VEGF, bFGF were obtained using cytometric bead array. Ten healthy volunteers were used as controls. Bone marrow MVD measured in hotspots was evaluated in 26 out of 38 patients at diagnosis and 15 patients with Hodgkin Lymphoma stage IA and IIA (used as controls) by staining immunohistochemically for CD34. Comparisons among groups were analyzed by ANOVA and the correlation by the Spearman's correlation coefficient. Cox regression were performed for overall survival (OS) analysis. Results Patients with MM had elevated TIMP-1, TIMP-2 and OPG values compared with controls. No significant difference was found between plasma sRANKL, pro-MMP2, pro-MMP9 and MMP-9 levels. We found that plasma TIMP-1 levels correlated positively with bFGF, VEGF, MVD, beta-2 microglobulin (B2M) and OPG (r: 0.514, p=0,001, r: 0.350, p=0,031; r: 0.610, p<0.0001; r: 0.760, p<0.0001 and r: 0.701, p<0.0001, respectively) and TIMP-2 levels with bFGF, DMV, B2M and OPG (r: 0.512, p=0.002; r: 0.595, p<0.0001; r: 0.587, p<0.0001 and r: 0.552, p<0.0001, respectively). TIMP-1 and TIMP-2 levels correlated with the ISS stage (p<0.0001, p=0.006, respectively). The only variables that correlated with clinical bone disease staging were hemoglobin, B2M and albumin levels, whereas TIMP-1, TIMP-2, bFGF, VEGF and OPG correlated with DMV. On the univariate analyses, age, gender, proMMP2, TIMP-1, TIMP-2, creatinine, B2M and MVD were significantly associated with overall survival. In Cox regression model, TIMP-1, TIMP-2 and B2M levels remained to be significantly associated with OS. In conclusion, our results suggest that TIMP-1 and TIMP-2 levels are strongly associated with neoangiogenesis and are independent prognostic factors in MM.

Abstract Abstract 5018 Background: Obesity was associated with a more than 2-fold greater risk of myelodysplastic syndrome (MDS) in a recent epidemiological study (Ma et al, Am J Epidemiol. 2009 June 15; 169(12): 1492–1499). The impact of obesity on outcome of disease in patients with an established diagnosis of MDS has not been studied. We examined the prognostic value of obesity in a large cohort of lower risk MDS patients treated at the Moffitt Cancer Center (MCC). Methods: Data were collected retrospectively from the Moffitt Cancer Center (MCC) MDS database and individual charts reviewed. The primary objective was to evaluate the impact of obesity on overall survival (OS) in lower risk patients with MDS. Patients with low or intermediate-1 (int-1) risk disease by International Prognostic Scoring System (IPSS) were included. Obesity was defined as a body mass index (BMI) ≥ 30 (Standard definition) measured at time of referral to MDS program at MCC. Patients were divided into two groups according to BMI ≥ 30 or BMI < 30. All analyses were conducted using SPSS version 19.0. Chi square and independent t-test were used to compare baseline characteristics between the 2 groups for categorical and continuous variables, respectively. The Kaplan–Meier method was used to estimate median overall survival. Log rank test was used to compare Kaplan–Meier survival estimates between two groups. Cox regression was used for multivariable analysis. Results: Between January 2001 and December 2009, 479 low/int-1 IPSS risk MDS patients were included. Among those, 132 (27.6%) had BMI ≥ 30 and 325 (67.8%) had BMI <30; BMI was missing in 22 patients (4.6%). The baseline characteristics between the two groups were comparable. No difference was noted in mean age, WHO subtype, karyotype, MD Anderson risk model group, red blood cell transfusion dependency (RBC-TD), or serum ferritin (Table-1). The median OS was 59 mo (95%CI 48–70) in patients with BMI <30 compared to 44 (95%CI 38–50) in patients with BMI ≥ 30. (p=0.03). There was no difference in rate of AML transformation according to BMI, 12.9% and 15.7% respectively for BMI ≥ 30 and BMI <30. (P=0.3). In Cox regression analysis obesity predicted inferior OS (Hazard ratio (HR) 1.7 (95%CI 1.15–2.4) (P=0.007) after adjustment for age, MD Anderson risk group, serum ferritin, RBC-TD, use of hypomethylating agents and tobacco use. Conclusion: Our data suggest that obesity is an independent adverse prognostic factor for OS in patients with lower risk MDS. Obesity may be associated with other comorbidities and metabolic dearrangements that contribute to the pathogenesis of the underlying disease.

Abstract Abstract 690 Background: There is limited information on the role of skeletal involvement in DLBCL patients treated with rituximab. Methods: In a retrospective subgroup analysis patients with aggressive B-cell lymphomas with and without skeletal involvement were compared with respect to clinical presentation, event-free and overall survival. Results: Of 3840 patients 292 (7.6%) had skeletal involvement. In a multivariable analysis of patients treated within the randomized MInT and RICOVER-60 trials, the two largest randomized trials addressing the role of rituximab in DLBCL to date, skeletal involvement was associated with a reduced hazard ratio (HR) of 0.8 (p=0.181) for event-free survival and 0.7 (p=0.083) for overall survival for patients treated without, but with an increased HR (1.5; p=0.048) for event-free and (1.1; p=0.828) for overall survival in patients treated with rituximab. This was due to the failure of rituximab to improve the outcome of patients with skeletal involvement. In the MInT trial, the 3-year EFS rates were 64% without and 63% with rituximab (p=0.680) and the 3-year OS rates were 83% without and 90% with rituximab (p=0.542). similarly, in the RICOVER-60 trial, the 3-year EFS rates were 45% without and 50% with rituximab (p=0.593) and the 3-year OS rates were 68% without and 68% with rituximab. In a Cox regression model for event-free survival adjusted for the IPI risk factors a relevant interaction (HR 1.5; p=0.056) term between rituximab and skeletal involvement was observed. In contrast to rituximab, additive radiotherapy to sites of skeletal involvement was associated with a better outcome: 3-year EFS rates were 40% without and 75% with radiotherapy (p<0.001), 3-year OS rates were 70% without and 86% with radiotherapy to sites of skeletal involvement (p=0.064). In a multivariable analysis radiotherapy reduced the risk for an event in EFS by 70% (HR=0.3; p=0.001) and by 50% in OS (HR=0.5; p=0.111). Conclusion: Addition of rituximab failed, but radiotherapy to sites of skeletal involvement did improve the outcome of DLBCL patients with skeletal involvement. Radiotherapy to sites of skeletal involvement, though abandoned by many cooperative groups world-wide, is recommended in the rituximab era, unless prospective trials demonstrate that it might be omitted in cases with a negative PET after immunochemotherapy.

3590 Background: In 2009, pts with M1 colorectal cancer were divided into two subsets for the American Joint Committee on Cancer (AJCC) 7th edition. Pts with metastases (mets) confined to one organ or site at initial diagnosis became stage M1a while multiple sites or peritoneal mets became M1b. The objectives of the study are to evaluate the impact of site of mets and M1a/b staging among pts with M1 colorectal cancer. Methods: All pts referred to the BC Cancer Agency from 1999-2007 with newly diagnosed M1 colon or rectal cancer were included. Demographic, treatment, and outcome data were prospectively collected. The prognostic impact of individual sites of mets was assessed by hazard ratio estimates from univariate Cox models. Multivariable Cox proportional-hazards models were used to determine variables associated with overall survival in the entire cohort and in those undergoing resection of their primary tumor. Results: 2,049 pts with M1 disease were included. Median age was 66 years; 71% had colonic origin; 70% had their primary tumor resected; and 69% received chemotherapy. In univariate analysis, solitary mets were associated with improved survival. In multivariable analysis, M1a/b status still had significant prognostic effect. The effect remained significant in the subgroup analysis of pts with resected primary tumors when histology, T and N stage were included. Conclusions: Pts with solitary mets, including peritoneum, have superior overall survival as compared to those with multiple sites of mets. AJCC 7th edition staging that includes M1a/b provides significant prognostic information and should be considered in clinical practice and trials of pts with M1 disease who otherwise have few prognostic factors.

165 Background: A complete pathologic response to induction CRT has been identified as a favorable prognostic factor for patients with LRA ACA of the E/GEJ. Less is known, however, about the impact of pathologic regression after induction chemotherapy. Methods: Between 2/08 and 1/12, 60 evaluable patients with ACA of the E/GEJ enrolled in a phase II trial of induction chemotherapy, surgery, and post-operative CRT. Eligibility required a clinical stage of T3 or N1 or M1a (AJCC 6th). Induction chemotherapy with epirubicin 50mg/m2 d1, oxaliplatin 130mg/m2 d1, and fluorouracil 200mg/m2/day continuous infusion for 3 weeks, was given every 21 days for 3 courses and was followed by surgical resection. Adjuvant CRT consisted of 50-55Gy @ 1.8-2.0 Gy/d and 2 courses of cisplatin (20mg/m2/d) and fluorouracil (1000mg/m2/d) over 4 days during weeks 1 and 4 of radiotherapy. RV was defined as the amount of remaining tumor in relation to acellular mucin pools and scarring. Results: Of the 60 evaluable patients, 54 completed induction therapy and underwent curative intent surgery. The Kaplan-Meier (KM) projected 3 year OS for patients with pathologic N0 (n=20), N1 (n=12), N2 (n=13), and N3 (n=9) disease is 73%, 57%, 35%, and 0% respectively (p<0.001). The KM projected 3 year OS of patients with low (0-25%, n=19), intermediate (26-75%, n=26), and high (>75%, n=9) RV was 67%, 42%, and 17% respectively (p=0.004). On multivariable analysis, both the pN descriptor and RV were independently prognostic for OS. In patients with less nodal dissemination (N0/N1), RV was prognostic for OS [3yr OS 85% (0-25% viable) v 51% (>25% viable), p=0.028]. Outcomes were poor, however, for patients with advanced nodal disease (N2/N3) regardless of RV [3yr OS 20% (0-25% viable) v 21% (>25% viable), p=0.55]. Conclusions: RV and the pN descriptor after induction chemotherapy are independent pathologic prognostic factors for OS in patients with LRA ACA of the E/GEJ. Patients with extensive nodal disease, however, have poor outcomes irrespective of viability. Clinical trial information: NCT00601705.

380 Background: IRGCT comprises a consistent category of metastatic patients (pts), and information on the recommended management of these pts should be updated. Usually they enter clinical trials for poor prognosis GCT. We aimed to address the heterogeneity of this category and to identify clinical prognostic factors for sub-stratification of pts. Methods: Data on consecutive pts with IRGCT and who received treatment at Fondazione INT Milano in the time-frame 02/1980-03/2014 were collected. Cox regression analyses were done evaluating potential prognostic factors for overall survival (OS, primary endpoint) to first-line therapy. Each factor was evaluated in a multivariable model. An exploratory OS comparison between outlier groups was undertaken with Kaplan Meier curves and logrank test. Results: Data on 181 pts were collected. Median age was 27 yrs (IQR 22-32), 10 pts had a retroperitoneal (RP) primary, 6 had pure seminoma. 72 (39.8%) had lung metastases and 54 (32.3%) bulky (i.e. ≥10cm) RP lymph-nodes (LN). Pts received cisplatin, bleomycin and etoposide (PEB, n=156) or vinblastine (PVB, n=23), 2 other treatments. Median follow up was 173 months (IQR: 87-237). Globally, 5-y PFS and OS were 66.8% (95%CI: 60.1-74.2) and 83.3% (77.8-89.2). However, 5-y OS for pts with AFP 5,000-10,000 IU/ml (N=19) was 61.8% (95%CI: 43.0-88.7) while it was 89.1% (95%CI: 81.2-97.7) for nonseminomas with elevated LDH only (N=57) and similar for elevated HCG only (N=22); overall p<0.001. Multivariable analysis for OS is shown in the table (c-index= 0.63). Distribution of variables over time: bulky RP LN and elevated LDH were more frequent in earlier series (p=0.003 and 0.011). Conclusions: The prognostic heterogeneity of IRGCT category is a matter of fact and should be addressed by clinical trials. Pts with highly elevated AFP have an OS similar to poor prognostic category, while those categorized by elevated HCG or LDH only are close to good risk ones. [Table: see text]

Meier Survival Curve

682 Background: Lymph node (LN) metastases affect overall survival (OS) in pancreatic cancer (PC). However, a LN sampling threshold does not exist. We examined the impact of nodal sampling on overall survival (OS). Methods: Patients with Stage I-III PC ≥55 years old who underwent curative resection from 2004-2016 were identified from the National Cancer Database (NCDB). After adjusting for age, gender, grade, stage, and Charlson-Deyo score, multiple binomial logistic regression analyses assessed the impact of the LN ratio (LNR) on OS. LNR was defined as the number of positive LN over the number of LN examined. Regression analyses, a Cox-Regression, and a Kaplan-Meier survival curve assessed how many LN should be sampled. Results: A total of 13,673 patients, median age 69 years (55-90), were included. Most were Caucasian (86.6%) males with Charlson-Deyo scores ≤ 1 (90.3%) and moderately to poorly differentiated PC (90.1%). Median number of LN examined was 15 (1-75) with a median of 1 positive LN (0-35). As expected, increased number of positive LNs was associated with reduced OS, p < 0.001. After data normalization, an increasing LNR was associated with a 12-fold likelihood of death [OR: 11.9, p < 0.001 (CI 6.0, 23.7)]. Subsequent regression models established evaluation of ≥ 16 LNs as the greatest predictor of OS. A regression model evaluating < or ≥ 16 lymph nodes was performed to ascertain the effects of age, gender, ethnicity, grade, stage, and LN examined on OS. The logistic regression model correctly classified 74.5% of cases with a specificity of 99.6% (p < 0.001). Examination of < 16 LN, Caucasian race, grade, stage, and higher Charlson-Deyo scores were significantly associated with decreased OS. If ≥ 16 LNs were examined, patients had a 1.5-fold likelihood of better OS, p < 0.001 (CI 1.4, 1.6). An adjusted Cox Regression showed increased HR of 1.2, p < 0.001 (CI 1.1, 1.2) and an unadjusted Kaplan Meier survival curve predicted ≥ 16 LN examined are associated with an increase in OS of 2.8 months [log-rank: 32.0, p < 0.001]. Conclusions: Patients undergoing curative intent resection for PC should have adequate nodal sampling. Stratification of patients by LNR may provide useful information of OS. Examination of ≥ 16 LNs impacts OS in patients with Stage I-III PC.

The Impact

The benefits of radiotherapy for colorectal cancer are well documented, but the impact of adjuvant radiotherapy on early-stage rectal adenocarcinoma remains unclear. This study aimed to identify predictors of overall survival (OS) and cancer-specific survival (CSS) in patients with stage II rectal adenocarcinoma treated with preoperative or postoperative radiation therapy. Patients with early-stage rectal adenocarcinoma in the postoperative state were identified using the Surveillance, Epidemiology, and End Results database. The primary endpoints were OS and overall CSS. Stage IIA patients without radiotherapy had significantly lower OS and CSS compared with those who received radiation before or after surgery. Stage IIB patients with radiotherapy before surgery had significantly higher OS and CSS compared with patients in the postoperative or no radiotherapy groups. Patients with signet ring cell carcinoma had the poorest OS among all the groups. Multivariable analysis showed that ethnicity (HR, 0.388, p=0.006) and radiation before surgery (HR, 0.614, p=0.006) were favorable prognostic factors for OS, while age (HR, 1.064, p<0.001), race (HR, 1.599, p=0.041), stage IIB (HR, 3.011, p=0.011), and more than one tumor deposit (TD) (HR, 2.300, p=0.001) were unfavorable prognostic factors for OS. Old age (HR, 1.047, p<0.00 L), stage IIB (HR, 8.619, p=0.005), circumferential resection margin between 0.1 mm and 10 mm (HR, 1.529, p=0.039), and more than one TD (HR, 2.688, p=0.001) were unfavorable prognostic factors for CSS. This population-based study identified predictors of OS and CSS in patients with early-stage resected rectal adenocarcinoma, which may help to guide future management of this patient population.
