7535 Background: CALGB 39801 was designed to test whether treatment with induction chemotherapy and concurrent chemoradiotherapy (arm B) would improve OS in comparison to identical chemoradiotherapy alone (arm A), and demonstrated no significant benefit in OS for induction therapy. The objective of this analysis was to identify factors predictive of OS, and to use relevant factors to dichotomize pts into prognostic groups. Methods: Between July 1998 and May 2002, 331 pts were studied and included in a Cox proportional hazard regression analysis investigating previously identified prognostic factors: age (< 70 vs. ≥ 70 years), gender, race/ethnicity, hemoglobin (hgb) (< 13 vs. ≥13), performance status (PS) (0 vs.1), pretreatment weight loss (wt loss) (<5% vs. ≥ 5%), and treatment arm. Results: Cox regression analysis identified weight loss ≥ 5%, age ≥ 70, PS of 1, and hgb < 13 as predictive of worse survival (p<0.05), but not treatment arm (p=0.55). The median survival for pts with 0 (n=66), 1 (n=100), 2 (n=100), or ≥ 3 (n=65) risk factors were 24, 18, 10, and 8 months, respectively (p=0.0001). The pts were dichotomized into “poor prognosis” (PP) defined as ≥2 factors (n=165) and “good prognosis” (GP) defined as ≤ 1 factors (n=166). The hazard ratio (HR) for overall survival for the PP in comparison GP was 1.88 (95% CI, 1.49 to 2.37; p-value < 0.0001); the median survival times (MST) observed were 9 and 18 months, respectively (p<0.0001). The reasons for discontinuing treatment, and the rates of hematologic and non-hematologic adverse events were similar between the two groups. In the PP group the OS was similar between arms A (n=82) and B (n=83) (HR=0.97, 95% CI, 0.70 to 1.4; p=0.34); MST of 8.7 and 9.5 months, respectively. In the GP the OS was similar between arms A (n=79) and B (n=87) (HR=0.86, 95% CI, 0.63 to 1.1; p=0.87); MST of 19.3 and 17.6 months, respectively. Conclusions: Factors predictive of OS can be used to dichotomize pts into prognostic groups. Induction chemotherapy was not beneficial in either prognostic group. No significant financial relationships to disclose.

ABSTRACT OBJECTIVE Stereotactic radiosurgery (SRS) has become an effective therapeutic modality for the treatment of patients with glioblastoma multiforme (GBM). This retrospective review evaluates the impact of SRS delivered on a gamma knife (GK) unit as an adjuvant therapy in the management of patients with GBM. METHODS Between August 1993 and December 1998, 82 patients with pathologically confirmed GBM received external beam radiotherapy (EBRT) at the University of Maryland Medical Center. Of these 82 patients, 64 with a minimum follow-up duration of at least 1 month are the focus of this analysis. Of the 64 assessable patients, 33 patients were treated with EBRT alone (Group 1), and 31 patients received both EBRT plus a GK-SRS boost (Group 2). GK-SRS was administered to most patients within 6 weeks of the completion of EBRT. The median EBRT dose was 59.7 Gy (range, 28–70.2 Gy), and the median GK-SRS dose to the prescription volume was 17.1 Gy (range, 10–28 Gy). The median age of the study population was 50.4 years, and the median pretreatment Karnofsky performance status was 80. Patient-, tumor-, and treatment-related variables were analyzed by Cox regression analysis, and survival curves were generated by the Kaplan-Meier product limit. RESULTS Median overall survival for the entire cohort was 16 months, and the actuarial survival rate at 1, 2, and 3 years were 67, 40, and 26%, respectively. When comparing age, Karnofsky performance status, extent of resection, and tumor volume, no statistical differences where discovered between Group 1 versus Group 2. When comparing the overall survival of Group 1 versus Group 2, the median survival was 13 months versus 25 months, respectively (P = 0.034). Age, Karnofsky performance status, and the addition of GK-SRS were all found to be significant predictors of overall survival via Cox regression analysis. No acute Grade 3 or Grade 4 toxicity was encountered. CONCLUSION The addition of a GK-SRS boost in conjunction with surgery and EBRT significantly improved the overall survival time in this retrospective series of patients with GBM. A prospective, randomized validation of the benefit of SRS awaits the results of the recently completed Radiation Therapy Oncology Group's trial RTOG 93-05.

Background: Cancer in a nonagenarian patient is rarely seen and there is always a moral dilemma for the family members and the patient as well of whether to opt for the treatment or not. Aim: The main aim was to identify the survival differences between treated and not treated nonagenarian cancer patients. Methods: This was a retrospective study of hospital-based cancer registry data from 2010 to 2016. The data of all nonagenarian cancer patients were analyzed for gender distribution, leading sites of cancer, stage distribution, types of treatment received, and survival. The survival was calculated from the date of first diagnosis. Descriptive statistics was used to present the results and presented up to single decimal place. Kaplan-Meier analysis was done to present the overall survival results and Cox-regression analysis was done to estimate the unadjusted HR. The P value for significance was set at < 0.05. SPSS v17.0 was used for carrying out the analysis. Results: Of 60,087 cancer patients registered during the study period, 146 (0.2%) patients were of 90 years and above. In males, hypopharynx in 19 (20.5%), lungs in 11 (10.3%), and esophagus in nine (8.4%) patients were top three leading sites. And in females, tongue in eight (20.5%), mouth in five (12.8%), and hypopharynx in four (10.3%) patients were the top leading sites. 60% patient data were in stages III and IV. Thirty seven (25.3%) patients received treatment, and 32 (86.4%) patients received radiotherapy alone. Five patients (13.5%) received combined modality of treatment. Two (5.4%) patients each received chemotherapy alone and surgery followed by radiotherapy for their cancer. Only one (2.5%) patient received concurrent chemo-radiotherapy. The median survival was nine months [confidence interval (CI) = 4.5-13.4]. The overall survival (OS) was 14.3% and the survival in the treatment group was 21.3% versus 7.7% in the Not Received, Abandoned, and Incomplete (NRAI) group (log rank (Mantel-Cox), P = 0.001). The unadjusted HR for NRAI group was 3.8 ( P = 0.003, CI=1.5-9.7). Conclusion: This analysis gives us some insight into the various types of cancer in the very old patients in our population. Selected nonagenarian cancer patients from our population with a favorable performance status should receive curative treatments in all possible ways. The improved overall survival and lower risk of death in nonagenarian cancer patients who received treatment in comparison with the NRAI group should aware the oncologist of the weighted benefits of curative treatment instead of plain palliation.

AbstractLung adenocarcinoma (LUAD) is the main pathological subtype of Non-small cell lung cancer. We downloaded the gene expression profile and immune-related gene set from the TCGA and ImmPort database, respectively, to establish immune-related gene pairs (IRGPs). Then, IRGPs were subjected to univariate Cox regression analysis, LASSO regression analysis, and multivariable Cox regression analysis to screen and develop an IRGPs signature. The receiver operating characteristic curve (ROC) was applied for evaluating the predicting accuracy of this signature by calculating the area under ROC (AUC) and data from the GEO set was used to validate this signature. The relationship of 22 tumor-infiltrating immune cells (TIICs) to the immune risk score was also investigated. An IRGPs signature with 8 IRGPs was constructed. The AUC for 1- and 3-year overall survival in the TCGA set was 0.867 and 0.870, respectively. Similar results were observed in the AUCs of GEO set 1, 2 and 3 (GEO set 1 [1-year: 0.819; 3-year: 0.803]; GEO set 2 [1-year: 0.834; 3-year: 0.870]; GEO set 3 [1-year: 0.955; 3-year: 0.827]). Survival analysis demonstrated high-risk LUAD patients exhibited poorer prognosis. The multivariable Cox regression indicated that the risk score was an independent prognostic factor. The immune risk score was highly associated with several TIICs (Plasma cells, memory B cells, resting memory CD4 T cells, and activated NK cells). We developed a novel IRGPs signature for predicting 1- and 3- year overall survival in LUAD, which would be helpful for prognosis assessment of LUAD.

Objective: Programmed cell death ligand 1 (PD-L1) and mammalian target of rapamycin (mTOR) are key players in host immune evasion and oncogenic activation, respectively. Evidence of the prognostic role in oral squamous cell carcinoma (OSCC) is conflicting. This study examined the associations of PD-L1 and mTOR expression with 5-year overall survival in OSCC patients. Material and Methods: The expressions of PD-L1 and mTOR proteins were immunohistochemically evaluated on tissue microarrays of 191 patients with OSCC who were treated by surgery at Songklanagarind Hospital, Thailand from 2008 to 2011. Cox regression analysis was used to determine independent prognostic factors. Results: PD-L1 expression was observed in 14.1% of cases while mTOR expression was present in 74.3% of cases. Females were more likely to have tumors with PD-L1 (p-value=0.007) and mTOR expressions (p-value=0.003) than males. In addition, lower clinical stage and well differentiated tumor are more likely to have mTOR expression (p-value= 0.038 and p-value<0.001, respectively). Cox regression analysis showed that age, tumor stage, nodal stage, combined surgical treatment with radiation or chemoradiation therapy, surgical margin status, PD-L1 expression and mTOR expression are independent prognostic factors. High PD-L1 expression (hazard ratio (HR) 3.14, 95% confidence interval (CI), 1.26–7.79) and high mTOR expression (HR 1.69, 95% CI, 1.00–2.84) are strong predictors of poor outcome. Conclusion: A proportion of OSCC expressed PD-L1 and mTOR proteins. Expression of PD-L1 and mTOR proteins are strong prognostic factors of OSCC.

ObjectiveGrowing evidence has highlighted that the immune and stromal cells that infiltrate in pancreatic cancer microenvironment significantly influence tumor progression. However, reliable microenvironment-related prognostic gene signatures are yet to be established. The present study aimed to elucidate tumor microenvironment-related prognostic genes in pancreatic cancer.MethodsWe applied the ESTIMATE algorithm to categorize patients with pancreatic cancer from TCGA dataset into high and low immune/stromal score groups and determined their differentially expressed genes. Then, univariate and LASSO Cox regression was performed to identify overall survival-related differentially expressed genes (DEGs). And multivariate Cox regression analysis was used to screen independent prognostic genes and construct a risk score model. Finally, the performance of the risk score model was evaluated by Kaplan-Meier curve, time-dependent receiver operating characteristic and Harrell’s concordance index.ResultsThe overall survival analysis demonstrated that high immune/stromal score groups were closely associated with poor prognosis. The multivariate Cox regression analysis indicated that the signatures of four genes, including TRPC7, CXCL10, CUX2, and COL2A1, were independent prognostic factors. Subsequently, the risk prediction model constructed by those genes was superior to AJCC staging as evaluated by time-dependent receiver operating characteristic and Harrell’s concordance index, and both KRAS and TP53 mutations were closely associated with high risk scores. In addition, CXCL10 was predominantly expressed by tumor associated macrophages and its receptor CXCR3 was highly expressed in T cells at the single-cell level.ConclusionsThis study comprehensively investigated the tumor microenvironment and verified immune/stromal-related biomarkers for pancreatic cancer.

Background: Liver progenitor cells (LPCs) play significant roles in the development and progression of hepatocellular carcinoma (HCC). However, no studies on the value of LPC-related genes for evaluating HCC prognosis exist. We developed a gene signature of LPC-related genes for prognostication in HCC. Methods: To identify LPC-related genes, we analyzed mRNA expression arrays from a dataset (GSE57812 & GSE 37071) containing LPCs, mature hepatocytes, and embryonic stem cell samples. HCC RNA-Seq data from The Cancer Genome Atlas (TCGA) were used to explore the differentially expressed genes (DEGs) related to prognosis through DEG analysis and univariate Cox regression analysis. Lasso and multivariate Cox regression analyses were performed to construct the LPC-related gene prognostic model in the TCGA training dataset. This model was validated in the TCGA testing set and an external dataset (International Cancer Genome Consortium [ICGC] dataset). Finally, we investigated the relationship between this prognostic model with tumor-node-metastasis stage, tumor grade, and vascular invasion of HCC. Results: Overall, 1770 genes were identified as LPC-related genes, of which 92 genes were identified as DEGs in HCC tissues compared with normal tissues. Furthermore, we randomly assigned patients from the TCGA dataset to the training and testing cohorts. Twenty-six DEGs correlated with overall survival (OS) in the univariate Cox regression analysis. Lasso and multivariate Cox regression analyses were performed in the TCGA training set, and a 3-gene signature was constructed to stratify patients into 2 risk groups: high-risk and low-risk. Patients in the high-risk group had significantly lower OS than those in the low-risk group. Receiver operating characteristic curve analysis confirmed the signature's predictive capacity. Moreover, the risk score was confirmed to be an independent predictor for patients with HCC. Conclusion: We demonstrated that the LPC-related gene signature can be used for prognostication in HCC. Thus, targeting LPCs may serve as a therapeutic alternative for HCC.

Abstract Background: Osteosarcoma is the most common primary malignant bone tumor. The current study was conducted to describe the general condition of patients with primary osteosarcoma in a single cancer center in Tianjin, China and to investigate the associated factors in osteosarcoma patients with lung metastasis. Methods: From February 2009 to October 2020, patients from Tianjin Medical University Cancer Institute and Hospital, China were retrospectively analyzed. The Kaplan–Meier method was used to evaluate the overall survival of osteosarcoma patients. Prognostic factors of patients with osteosarcoma were identified by the Cox proportional hazard regression analysis. Risk factor of lung metastasis in osteosarcoma were investigated by the logistic regression model. Results: A total of 203 patients were involved and 150 patients were successfully followed up for survival status. The 5-year survival rate of osteo-sarcoma patients was 70.0%. Surgery, bone and lung metastasis were the significant prognostic factors in multivariable Cox regression analysis. Twenty-one (10.3%) patients showed lung metastasis at the diagnosis of osteosarcoma and 67 (33%) lung metastases during the later course. T3 stage (OR=11.415, 95%CI 1.362-95.677, P=0.025) and synchronous bone metastasis (OR=6.437, 95%CI 1.69-24.51, P=0.006) were risk factors of synchronous lung metastasis occurrence. Good necrosis (≥90%, OR=0.097, 95%CI 0.028-0.332, P=0.000) and elevated Ki-67 (≥50%, OR=4.529, 95%CI 1.241-16.524, P=0.022) were proved to be significantly associated with metachronous lung metastasis occurrence. Conclusion: The overall survival, prognostic factors and risk factors for lung metastasis in this single center provided insight about osteosarcoma management.

Abstract Objectives Identify the predictors of acute malnutrition in rural twins in a context of dietary supplementation in Burkina Faso. Methods This is a prospective cohort study. A cox regression was used to investigate predictors of acute malnutrition. A significance threshold of 0.05 was considered. Results Severe acute malnutria was more common in twins compared to non-twins (22.13% vs. 9.98%, P-0.001). Growth retardation was more common in twins compared to non-twins (34.04% vs. 21.49%, P-0.001). Underweight was more common in twins compared to non-twins (1.70% versus 0.43%). This difference was not statically significant (P-0.06). In multi-varied cox regression analysis, the factors significantly associated with acute malnutrition were: being born twins, episodes of fevers, diarrhea, and wealth level. Twins were almost twice as likely to be malnourished compared to single children (HRa −1.82, IC95% - [1.59–2.07] and P-0.001). Children with a fever were 2.54 more likely to be malnourished than other children. (HRa - 2.15, IC95% - [1.74–2.67] and P-0.001). Children with diarrhea were 2.54 more likely to be malnourished than other children. (HRa - 2.05, IC95% - [1.62–2.59] and P-0.001). Children born in a wealthy household were 25% less likely to be malnourished compared to other children (HRa-0.75; IC95%, [0.61–0.92]; P-value-0.007). Conclusions Particular attention should be paid to twins, in order to reduce the risk of acute malnutrition before their second birthday. Funding Sources None.

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.

18211 Background: Prognostic factors identified in advanced non small cell lung cancer are: age, gender, PS, h. SWOG univariable analysis in patients with chemotheraphy; confirmed these factors and show a relationship between the hemoglobin level and the overall survival; in addition the metastasic site number and cisplatin- based chemotheraphy (7). To analyse and compare the hemoglobin level before cisplatin- based chemotheraphy with survival in patients with advanced non- small cell lung cancer. Methods: Retrospective study conducted at the IONC of the 179 clinical record were analized, over a 5 year period. The collected data were: age, gender, PS, histologic type, stage, chemotheraphy cycles number, smooke history, number and metastasic site. We analyzed median and overal survival using Kaplan Meier, and the anemia as a prognostic implication factor with univariable and multivariable Cox regression analysis. Istologic type and TNM (1–6). Results: The mean age was 59 (40–79); 146 (81.5%) male and 33 (18.5%) women; histological types found were squamous cell carcinomas in 66 (37%), and adenocarcinoma in 113 (63%); stage IIIB in 61 (34%) and IV in 118 (66%). 147 (82%) were smokers and 32 (18%) were never smokers. All the patients had PS 0–1. Median overall survival time was 11.53 months and 13.88 months in the haemoglobin level < or > 11 gr/ 100 ml, respectively. (p=0.3). In univariable Cox regression analysis, smoking rates and chemotheraphy cycles number were predictors of survival (p=0.05 y p=0.018, respectively). Hemoglobine (p=0.55). In multivariable Cox regression analysis, only the number of cycles was predictor of survival (p=0.026). Hemoglobine (p=0.34). Conclusions: In our experience, a greater survival tendency was observed in patients with advanced non- small cell lung cancer who presented levels of Hemoglobine greater than 11 gr/dl, previous to cisplatin- based chemotherapy without statistical significance.
