Abstract
Abstract
There is a paucity of data on Oncotype DX DCIS Score and ethnic variation. It has been postulated that there are different molecular features /drivers among different ethnic populations. The Oncotype DX DCIS Score is a genomic test designed to analyze the expression of a group of 12 genes which can quantify 10-year local recurrence risk after surgery. The purpose of this study is to evaluate diverse ethnic patients with DCIS relative to traditional clinical pathologic factors and Oncotype DX DCIS Score
We analyzed consecutive cases of DCIS from 2011-2017 who underwent Oncotype DX DCIS Score testing at a single institution. Eighty-four female patients were divided into 5 groups based on self-reported ethnicity: White (36%), African American (AA) (48%), Asian (8%), Hispanic (4%) and Other (4%). Clinical and traditional pathologic factors were collected including age, nuclear grade (NG), ER/PR status and Oncotype DX DCIS Score. The distribution of NG and Oncotype DX DCIS Score was analyzed across ethnic groups.
The mean age at diagnosis was 63. Overall 99 % of cases were hormone positive. Comparison of White and AA patients revealed a correlation between ethnic group and DCIS Score, with a p value of 0.0087 (Table 1). Similarly, we looked at all five ethnic groups and Oncotype DX DCIS Score and found a p value of 0.022. We evaluated ethnicity with White and AA patients versus NG and obtained a p value of 0.084 (Table 2). In addition, we assessed all five ethnic groups and NG. We obtained a p value of 0.068. No AA patients with DCIS had a high DCIS Score. No patients with low NG DCIS had a high DCIS Score. Analysis of the three factors (NG, ethnicity and DCIS Score) concurrently showed that they are not independent.
In summary, our study provides valuable data on Oncotype DX DCIS Score and NG across a diverse patient population. These data highlight the importance of incorporating both traditional clinical pathologic factors and DCIS Score molecular testing for making treatment decision across different ethnic patient populations.

Abstract
OBJECTIVE There are variable reports of risk of concordance for progression to islet autoantibodies and type 1 diabetes in identical twins after one twin is diagnosed. We examined development of positive autoantibodies and type 1 diabetes and the effects of genetic factors and common environment on autoantibody positivity in identical twins, nonidentical twins, and full siblings. RESEARCH DESIGN AND METHODS Subjects from the TrialNet Pathway to Prevention Study (N = 48,026) were screened from 2004 to 2015 for islet autoantibodies (GAD antibody [GADA], insulinoma-associated antigen 2 [IA-2A], and autoantibodies against insulin [IAA]). Of these subjects, 17,226 (157 identical twins, 283 nonidentical twins, and 16,786 full siblings) were followed for autoantibody positivity or type 1 diabetes for a median of 2.1 years. RESULTS At screening, identical twins were more likely to have positive GADA, IA-2A, and IAA than nonidentical twins or full siblings (all P < 0.0001). Younger age, male sex, and genetic factors were significant factors for expression of IA-2A, IAA, one or more positive autoantibodies, and two or more positive autoantibodies (all P ≤ 0.03). Initially autoantibody-positive identical twins had a 69% risk of diabetes by 3 years compared with 1.5% for initially autoantibody-negative identical twins. In nonidentical twins, type 1 diabetes risk by 3 years was 72% for initially multiple autoantibody-positive, 13% for single autoantibody-positive, and 0% for initially autoantibody-negative nonidentical twins. Full siblings had a 3-year type 1 diabetes risk of 47% for multiple autoantibody-positive, 12% for single autoantibody-positive, and 0.5% for initially autoantibody-negative subjects. CONCLUSIONS Risk of type 1 diabetes at 3 years is high for initially multiple and single autoantibody-positive identical twins and multiple autoantibody-positive nonidentical twins. Genetic predisposition, age, and male sex are significant risk factors for development of positive autoantibodies in twins.

Abstract
In this study, we conducted a model of teacher professional development (PD) on the alignment of middle and high school curricula and instruction to the Next Generation Science Standards (NGSSs), and evaluated the impact of the PD on teacher participants' development. The PD model included a 4-day summer academy emphasizing project-based learning (PBL) in the designing of NGSS-aligned curricula and instruction, as well as monthly follow-up Professional Learning Community meetings throughout the year providing numerous opportunities for teachers to develop and implement lesson plans, share results of lesson writing and implementation (successes and challenges), provide mutual feedback, and refine curricula and assessments. Following the summer academy, six female teachers were interviewed about their current conceptualizations of NGSS, the extent of curricular shifts made that are required by NGSS, their self-perceptions regarding their level of accomplishment in curriculum writing, and the benefits of the PD in reaching their goals related to NGSS. Interviews were supplemented with an analysis of lesson plans written while participating in the PD program. The interviewed teachers suggested that they had made important conceptual and pedagogical shifts required by NGSS as they participated in the PD, and also noted a variety of challenges as they made this shift. While all teachers were relative novices at NGSS curriculum writing before the PD, most of the teachers interviewed felt that they had achieved the status of an "accomplished novice" following the summer academy. An analysis of their written lessons suggested a great range in the extent to which teachers effectively applied their understanding of NGSS to write lessons aligned to NGSS. Interviewed teachers believed that the PD model was helpful to their development as science teachers, and all reported that there were no aspects of the PD that were not helpful. Even though most teachers obtained a basic understanding and conceptualization of NGSS and PBL, their application of this understanding in their curriculum writing varied. The present study may help to inform future efforts to support teachers to align curricula and instruction to NGSS through teacher PD.

Abstract
Assistive technology is a rapidly growing field that provides a degree of freedom and self-sufficiency to people of limited mobility. Smart wheelchairs are a subset of assistive technology, and are designed to be operated by people who are unable to use a traditional control system. Instead, smart wheelchairs are equipped with a combination of automated functionality and steering mechanisms specialized to meet a persons individual needs. One feature common to the automated capabilities of smart wheelchairs is the tracking system. The wheelchairs microcontroller needs to know how far the chair has travelled, its speed, and the rotational direction of its wheels in order to successfully navigate through an environment. The purpose of this research was to develop an odometer to track the motion of a motorized wheelchair. Due to federal regulations that prohibit changing the structure or internal mechanics of a medical device, the odometer had to be designed as a separate, removable part. The final design for the odometer consisted of two infrared sensors that measure edge transitions of a segmented black and white encoder wheel. The sensor output was then run through two comparator op amps and a high pass filter to produce a clean, crisp square wave signal output. The signal was then fed to an Atmel ATmega164P microcontroller. The microcontroller was programmed to compare the sensor signal with its internal clock, sense edge transitions, and thereby extrapolate the speed, travelled distance, and rotational direction of the wheelchair.

Abstract
BACKGROUND AND PURPOSE The Echoplanar Imaging Thrombolysis Evaluation Trial (EPITHET) tests the hypothesis that perfusion-weighted imaging (PWI)-diffusion-weighted imaging (DWI) mismatch predicts the response to thrombolysis. There is no accepted standardized definition of PWI-DWI mismatch. We compared common mismatch definitions in the initial 40 EPITHET patients. METHODS Raw perfusion images were used to generate maps of time to peak (TTP), mean transit time (MTT), time to peak of the impulse response (Tmax) and first moment transit time (FMT). DWI, apparent diffusion coefficient (ADC), and PWI volumes were measured with planimetric and thresholding techniques. Correlations between mismatch volume (PWIvol-DWIvol) and DWI expansion (T2(Day 90-vol)-DWI(Acute-vol)) were also assessed. RESULTS Mean age was 68+/-11, time to MRI 4.5+/-0.7 hours, and median National Institutes of Health Stroke Scale (NIHSS) score 11 (range 4 to 23). Tmax and MTT hypoperfusion volumes were significantly lower than those calculated with TTP and FMT maps (P<0.001). Mismatch > or =20% was observed in 89% (Tmax) to 92% (TTP/FMT/MTT) of patients. Application of a +4s (relative to the contralateral hemisphere) PWI threshold reduced the frequency of positive mismatch volumes (TTP 73%/FMT 68%/Tmax 54%/MTT 43%). Mismatch was not significantly different when assessed with ADC maps. Mismatch volume, calculated with all parameters and thresholds, was not significantly correlated with DWI expansion. In contrast, reperfusion was correlated inversely with infarct growth (R=-0.51; P=0.009). CONCLUSIONS Deconvolution and application of PWI thresholds provide more conservative estimates of tissue at risk and decrease the frequency of mismatch accordingly. The precise definition may not be critical; however, because reperfusion alters tissue fate irrespective of mismatch.

Abstract
An exact steady-state solution of the stochastic equations governing the behavior of a gene regulated by a self-generated proteomic atmosphere is presented. The solutions depend on an adiabaticity parameter measuring the relative rate of DNA-protein unbinding and protein degradation. The steady-state solution reveals deviations from the commonly used Ackers et al approximation based on the equilibrium law of mass action, allowing anticooperative behavior in the "nonadiabatic" limit of slow binding and unbinding rates. Noise from binding and unbinding events dominates the shot noise of protein synthesis and degradation up to quite high values of the adiabaticity parameter.

Abstract
Carbon nitride nanostructures have been produced by the arc-discharge technique and analyzed by mass spectrometry. A series of structured peaks in the region of masses from 480 up to 600 suggests the existence of heterofullerenes C(n-x)Nx(40 < or = n < or = 50). The structure and stability of these small fullerenes were theoretically investigated by quantum chemical calculations. The obtained heats of formation indicate that C(n) molecules stabilize upon nitrogen substitution. Two C(n-x)Nx cages are quite stable, with heats of formation per atom approaching that of C60. These molecules could be the seeds of onion-like structures seen in CN materials [Phys. Rev. Lett. 87, 225503 (2001)]].

Abstract
PURPOSE We evaluated the ability of previously defined risk groups to predict prostate specific antigen (PSA) outcome 10 years after radical prostatectomy in patients diagnosed with clinically localized prostate cancer during the PSA era. MATERIALS AND METHODS Between 1989 and 2000, 2,127 men with clinically localized prostate cancer underwent radical prostatectomy, including 1,027 at Hospital of the University of Pennsylvania (study cohort) and 1,100 at Brigham and Women's Hospital (validation cohort). Cox regression analysis was done to calculate the relative risk of PSA failure with the 95% confidence interval (CI) in patients at intermediate and high versus low risk. The Kaplan-Meier actuarial method was used to estimate PSA outcome 10 years after radical prostatectomy. RESULTS Compared with low risk patients (stages T1c to 2a disease, PSA 10 ng./ml. or less and Gleason score 6 or less) the relative risk of PSA failure in those at intermediate (stage T2b disease or PSA greater than 10 to 20 ng./ml. or less, or Gleason score 7) and high (stage T2c disease, or PSA greater than 20 ng./ml. or Gleason score 8 or greater) risk was 3.8 (95% CI 2.6 to 5.7) and 9.6 (95% CI 6.6 to 13.9) in the study cohort, and 3.3 (95% CI 2.3 to 4.8) and 6.3 (95% CI 4.3 to 9.4) in the validation cohort. The 10-year PSA failure-free survival rate in the 1,020 patients in the low, 693 in the intermediate and 414 in the high risk groups was 83%, 46% and 29%, respectively (p <0.0001). CONCLUSIONS Based on 10-year actuarial estimates of PSA outcome after radical prostatectomy 3 groups of patients were identified using preoperative PSA, biopsy Gleason score and 1992 clinical T category.

Abstract
We examined the relations of verbal ability and self-regulation in preschool to emotion knowledge in first grade, and concurrent relations between emotion knowledge and indexes of social functioning in 143 children from low-income families. After controlling for children's verbal ability in preschool, teacher reports of attentional control and caregiver reports of behavioral control in preschool predicted children's emotion expression knowledge and emotion situation knowledge 2 years later. After controlling for verbal ability and attentional and behavioral control, children's emotion knowledge predicted concurrent teacher-reported social problems and social withdrawal. Results suggest that low levels of emotion knowledge co-occur with many important aspects of children's early social adaptation.

Abstract
OBJECTIVES Whether early detection using prostate-specific antigen (PSA) and digital rectal examination (DRE) compared with DRE alone will reduce prostate cancer mortality awaits the results of ongoing prospective randomized trials. However, the impact that early detection could have on prostate cancer-specific survival can be estimated by assuming that PSA failure after radical prostatectomy (RP) will translate into death from prostate cancer. METHODS The study population consisted of 1274 men with clinically localized prostate cancer who underwent RP in Boston, Massachusetts or Philadelphia, Pennsylvania between 1989 and 2000 and had a preoperative PSA level greater than 4 but not more than 10 ng/mL. The primary endpoint was actuarial freedom from PSA failure (defined as PSA outcome). RESULTS The relative risk of PSA failure after RP for patients diagnosed with a PSA of greater than 4 to 5, 5 to 6, 6 to 7, or 7 to 8 ng/mL compared with greater than 8 up to 10 ng/mL was 0.3 (95% confidence interval [CI] 0.2 to 0.5), 0.5 (95% CI 0.4 to 0.8), 0.6 (95% CI 0.4 to 0.9), or 0.9 (95% CI 0.6 to 1.3), respectively. On the basis of the estimates of the 5-year PSA outcome, patients with a biopsy Gleason score of 5 or 6 (781 of 1274; 61%) consistently benefited from RP performed when the PSA at diagnosis was greater than 4 to 7 ng/mL compared with greater than 8 to 10 ng/mL (93% versus 78%, P <0.0001). A benefit to early detection was not found for the vast majority (266 of 312; 88%) of patients who had a biopsy Gleason score of 7 or higher. CONCLUSIONS Early detection using both PSA and DRE-based screening may benefit men who present with biopsy Gleason score 5 or 6 prostate cancer and a PSA level greater than 4 to 7 ng/mL compared with greater than 8 up to 10 ng/mL. This finding awaits validation from ongoing prospective randomized trials.

Abstract
This study examined the relations among family structure, caregiver relationship history, aspects of environmental adversity, and teacher reports about the externalizing behaviors of 6- and 7-year-old children from economically disadvantaged families. Family structure contrasted intact families, stepfamilies, single-parent families, and cohabiting families. Problem behaviors were more frequent for children from unmarried families than from married families and were more frequent for boys than for girls from cohabiting families. Relationship history reduced the effects for family structure. Children's adjustment varied with both the current status and past stability of caregiver intimate relationships for disadvantaged families.

Abstract
PURPOSE An investigation was performed of the clinical utility of the percent of positive prostate biopsies in predicting prostate-specific antigen (PSA) outcome following external-beam radiation therapy (RT) for men with PSA-detected or clinically palpable prostate cancer. METHODS AND MATERIALS A Cox regression multivariable analysis was used to determine whether the percent of positive prostate biopsies provided clinically relevant information about PSA outcome following external beam RT in 473 men while accounting for the previously established risk groups based on the pretreatment PSA level, biopsy Gleason score, and the 1992 American Joint Commission on Cancer (AJCC) clinical T stage. RESULTS Controlling for the known prognostic factors, the percent of positive prostate biopsies added clinically significant information (p = 0.02) regarding time to PSA failure following RT. Specifically, 76% of the patients in the intermediate risk group (1992 AJCC T(2b) or biopsy Gleason 7 or PSA > 10 ng/mL and < or = 20 ng/mL) could be classified into either an 30% or 85% 5-year PSA control cohort using the preoperative prostate biopsy data. CONCLUSION The previously validated stratification of PSA outcome following radical prostatectomy (RP) using the percent of positive prostate biopsies in intermediate-risk patients is also clinically significant for men treated with external beam RT. The percent positive prostate biopsies should be considered in conjunction with the PSA level, biopsy Gleason score, and 1992 AJCC clinical T stage when counseling patients with newly diagnosed and clinically localized prostate cancer about PSA outcome following RP or external beam RT.

Abstract
PURPOSE Patients at low risk for prostate-specific antigen (PSA) failure following definitive local therapy are those with PSA of 10 or less, biopsy Gleason Score of 6 or less, and 1992 American Joint Committee on Cancer (AJCC) clinical Stage T1c or T2a. However, low-risk patients managed with radical prostatectomy and found to have prostatectomy Gleason score > or = 3+4 have a less favorable PSA outcome when compared to patients with prostatectomy Gleason score < or = 3+3. This study was performed to determine whether the percentage of positive prostate biopsy cores could predict upgrading from a biopsy Gleason score of 6 or less to a prostatectomy Gleason score > or = 3+4 in low-risk patients to optimize selection for prostate only radiation therapy. METHODS AND MATERIALS Concordance testing of the biopsy Gleason score and the primary and secondary prostatectomy Gleason grades was performed in 427 prostate cancer patients treated with radical prostatectomy and at low risk for PSA failure. Logistic regression multivariable analysis was performed to test the ability of the established prognostic factors and the percentage of positive prostate biopsies (<34%, 34-50%, >50%) to predict for upgrading from biopsy Gleason score of 6 or less prostatectomy Gleason score > or = 3+4. PSA failure-free survival was reported using the actuarial method of Kaplan and Meier and comparisons were made using a log-rank test. RESULTS Twenty-nine percent of the 427 study patients were upgraded from a biopsy Gleason score of 6 or less to a prostatectomy Gleason score > or = 3+4. The presence of greater than 50% positive biopsies was the only significant factor for predicting the upgrading from biopsy Gleason score of 6 or less to prostatectomy Gleason score > or = 3+4 on logistic regression multivariable analysis with the variables treated as continuous and categorical. Specifically, upgrading occurred in 26% vs. 59% of patients with 50% or less vs. greater than 50% positive biopsies, respectively. This translated into a 5-year PSA failure-free survival which was significantly higher (92% vs. 62%, p = 0.00001) for men with 50% or less vs. greater than 50% positive prostate biopsies, respectively. CONCLUSION The presence of greater than 50% positive biopsies was associated with higher rates of pathologic upgrading which translated into lower 5-year PSA failure-free survival following radical prostatectomy (RP). Therefore, the percentage of positive biopsies may be useful in optimizing the selection of low-risk patients for prostate only radiation therapy such as external beam radiation or implant monotherapy.

Abstract
BACKGROUND AND PURPOSE The clinical utility of the percentage of positive prostate biopsies in predicting prostate specific antigen (PSA) outcome after radical prostatectomy (RP) or external-beam radiation therapy (EBRT) for men with PSA-detected or palpable prostate cancer is not established. METHODS A Cox regression multivariable analysis was used to determine whether percent-positive prostate biopsies provided clinically relevant information about PSA outcome after RP in 960 men, while accounting for the previously established risk groups based on the pretreatment PSA concentration biopsy Gleason score, and the 1992 American Joint Commission on Cancer clinical T stage. RESULTS In the intermediate-risk group, 80% of the patients (stage T(2b) or biopsy Gleason 7 or PSA 10-20 ng/mL) could be classified into either an 11% or an 86% 4-year PSA control cohort using the preoperative prostate biopsy data. These findings were validated using an independent surgical (N = 823) and radiation (N = 473) data set. Percent-positive prostate biopsies added clinically significant information regarding time to PSA failure after RP. CONCLUSIONS The percentage of positive prostate biopsies should be considered in conjunction with the PSA level, biopsy Gleason score, and clinical T stage when counseling patients with newly diagnosed and clinically localized prostate cancer about PSA outcome after RP or EBRT.

Abstract
Following leads from differential emotions theory and empirical research, we evaluated an index of emotion knowledge as a long-term predictor of positive and negative social behavior and academic competence in a sample of children from economically disadvantaged families (N = 72). The index of emotion knowledge represents the child's ability to recognize and label emotion expressions. We administered control and predictor measures when the children were 5 years old and obtained criterion data at age 9. After controlling for verbal ability and temperament, our index of emotion knowledge predicted aggregate indices of positive and negative social behavior and academic competence. Path analysis showed that emotion knowledge mediated the effect of verbal ability on academic competence. We argue that the ability to detect and label emotion cues facilitates positive social interactions and that a deficit in this ability contributes to behavioral and learning problems. Our findings have implications for primary prevention.

Abstract
CONTEXT Combined treatment using radiation therapy (RT) and androgen suppression therapy (AST) is used to treat men with clinically localized adenocarcinoma of the prostate, but outcome using this combined therapy compared with RT alone is not known. OBJECTIVE To determine the relative efficacy of RT plus AST vs RT alone among men with clinically localized prostate cancer. DESIGN, SETTING, AND PATIENTS Retrospective cohort study of 1586 men with prostate cancer who were treated between January 1989 and August 1999 using 3-dimensional conformal RT with (n = 276) or without (n = 1310) 6 months of AST. MAIN OUTCOME MEASURE Relative risk (RR) of prostate-specific antigen (PSA) failure (defined according to the American Society for Therapeutic Radiology and Oncology consensus statement), by treatment and high-, intermediate-, or low-risk group based on serum PSA level, biopsy Gleason score, and 1992 American Joint Commission on Cancer clinical tumor category. RESULTS Estimates of 5-year PSA outcome after RT with or without AST were not statistically different among low-risk patients (P =.09), whereas intermediate- and high-risk patients treated with RT plus AST had significantly better outcomes than those treated with RT alone (P<.001 and =.009, respectively). The RR of PSA failure in low-risk patients treated with RT plus AST was 0.5 (95% confidence interval [CI], 0.3-1.1) compared with patients treated with RT alone. The RRs of PSA failure in intermediate-risk and high-risk patients treated with RT plus AST compared with RT alone were 0.2 (95% CI, 0. 1-0.3) and 0.4 (95% CI, 0.2-0.8), respectively. CONCLUSIONS Our data suggest a significant benefit in 5-year PSA outcomes for men with clinically localized prostate cancer in intermediate- and high-risk groups treated with RT plus AST vs those treated with RT alone. Results from prospective randomized trials currently under way are needed to validate these findings. JAMA. 2000;284:1280-1283

Abstract
PURPOSE Endorectal magnetic resonance imaging (MRI) of the prostate is sometimes performed before radical prostatectomy but to our knowledge its role for predicting outcome after radical prostatectomy is not yet established. We evaluated the clinical usefulness of endorectal MRI for predicting time to prostate specific antigen (PSA) failure after radical prostatectomy in 1,025 consecutive men with clinically localized or PSA detected prostate cancer. Our analysis controlled for PSA level, biopsy Gleason score, clinical T stage and percent of positive biopsies. MATERIALS AND METHODS Using Cox regression analysis we prospectively assessed time to PSA failure to determine the role of endorectal MRI in predicting PSA outcome after radical prostatectomy at our institution, where an expert prostate magnetic resonance radiologist is available. The main outcome measure was actuarial freedom from PSA failure. RESULTS Endorectal MRI did not add clinically meaningful information in 834 of our 1,025 cases (81%) after accounting for the prognostic value of PSA, biopsy Gleason score, clinical T stage and percent of positive biopsies. However, this modality provided a clinically and statistically relevant stratification of 5-year PSA outcome in the remaining 191 patients at intermediate risk based on established prognostic factors. Specifically when endorectal MRI was interpreted as indicating extracapsular versus organ confined disease the relative risk of PSA failure was 3.6 (95% confidence interval 2.0 to 6.3), and 5-year actuarial freedom from PSA failure was 33% versus 72% (p <0.0001). CONCLUSIONS Despite expert radiological interpretation endorectal MRI had potential clinical value in less than 20% of the cases in our study after accounting for established prognostic factors. While further study of the value of this modality for predicting clinical outcome after radical prostatectomy should be performed in this select cohort, routine use of endorectal MRI cannot be justified based on these data.

Abstract
There is an accumulating body evidence that atherosclerosis is either caused by or accompanied by oxidative events in the vessel wall. These oxidative events have been implicated in proatherogenic modification of proteins, alteration of gene expression, promotion of inflammation, remodeling of vessels, and perturbations of vascular tone. This body of literature has led to a dogma that oxidation is a prerequisite for the atherosclerotic process. In particular, oxidation of lipoproteins by activated macrophages in the subintimal space has been postulated to be an important early step in the atherosclerotic process.

Abstract
PURPOSE We evaluated the impact that the composition of prognostic factors in a patient cohort may have on prostate specific antigen (PSA) outcome following external beam radiation therapy for clinically localized prostate cancer. MATERIALS AND METHODS The distribution of PSA, biopsy Gleason score and American Joint Committee on Cancer (AJCC) T stage in men with prostate cancer treated with interstitial plus external beam radiation therapy was used to select a matched cohort who underwent 3-dimensional (D) conformal external beam radiation therapy. We compared PSA outcomes after 3-D conformal external beam radiation therapy in the overall and matched cohorts of 766 and 570 patients, respectively. RESULTS Men treated with interstitial plus external beam radiation therapy had a significantly lower rate of PSA greater than 10 to 20 (p = 0. 02) and greater than 20 ng./ml. (p <0.0001), biopsy Gleason score 7 (p = 0.02) and 8 to 10 (p <0.0001), and AJCC stage T2c disease (p <0. 0001). Likewise, these men also had a significantly higher rate of PSA greater than 4 to 10 ng./ml. (p <0.0001), biopsy Gleason score 5 to 6 (p = 0.0001) and AJCC stage T1 disease (p <0.0001) than those who underwent 3-D conformal external beam radiation therapy. The 5-year estimate of PSA failure-free survival after 3-D conformal external beam radiation therapy was 45% versus 67% (p = 0.0007) for all 766 consecutively treated patients and the matched cohort of 570, respectively. CONCLUSIONS The composition of prognostic factors in a patient cohort may impact PSA outcome. Therefore, controlling for established prognostic factors is essential when comparing PSA outcome after different forms of radiotherapy for adenocarcinoma of the prostate.

Abstract
BACKGROUND Early (< or = 2 years) prostate specific antigen (PSA) failure after radical prostatectomy (RP) has been shown to predict for distant failure. After excluding patients with the pathologic predictors of early PSA failure, an analysis of PSA failure free (bNED) survival was performed to identify patients who may benefit from the use of postprostatectomy radiation therapy (RT). METHODS Of 1,028 patients treated with RP for clinically localized prostate carcinoma between 1989 and 1999, 862 (84%) had either organ confined (OC), specimen confined (SC), or margin positive disease with negative seminal vesicles (SV) and a prostatectomy Gleason score < or = 7. A Cox regression multivariate analysis was performed in these patients evaluating the ability of the extent of extracapsular extension (ECE) (into but not through the capsule, SC focal ECE, SC established ECE, margin positive) and prostatectomy Gleason score (2-6 vs. 7) to predict time to postoperative PSA failure. RESULTS SC focal ECE (P = 0.0017), SC established ECE (P < 0.0001), and margin positive disease (P < 0.0001) were significant predictors of time to postoperative PSA failure, whereas prostatectomy Gleason score and disease extending into but not through the capsule were not. Five-year bNED rates were 90%, 88%, 69%, 45%, and 33% for patients with OC, into but not through capsule, SC focal ECE, SC established ECE, and margin positive prostate carcinoma, respectively. CONCLUSIONS Patients with SC ECE or margin positive prostate carcinoma and a prostatectomy Gleason score < or = 7 with no evidence of SV invasion may benefit from adjuvant postoperative RT.

Abstract
PURPOSE To determine the clinical utility of the percentage of positive prostate biopsies in predicting prostate-specific antigen (PSA) outcome after radical prostatectomy (RP) for men with PSA-detected or clinically palpable prostate cancer. METHODS A Cox regression multivariable analysis was used to determine whether the percentage of positive prostate biopsies provided clinically relevant information about PSA outcome after RP in 960 men while accounting for the previously established risk groups that are defined according to pretreatment PSA level, biopsy Gleason score, and the 1992 American Joint Committee on Cancer (AJCC) clinical T stage. The findings were then tested using an independent surgical database that included data for 823 men. RESULTS Controlling for the known prognostic factors, the percentage of positive prostate biopsies added clinically significant information (P <.0001) regarding time to PSA failure after RP. Specifically, 80% of the patients in the intermediate-risk group (1992 AJCC T2b, or biopsy Gleason 7 or PSA > 10 ng/mL and </= 20 ng/mL) could be classified into either an 11% or 86% 4-year PSA control cohort using the preoperative prostate biopsy data. These findings were validated in the intermediate-risk patients using an independent surgical data set. CONCLUSION The validated stratification of PSA outcome after RP using the percentage of positive prostate biopsies in intermediate-risk patients is clinically significant. This information can be used to identify men with newly diagnosed and clinically localized prostate cancer who are at high risk for early (</= 2 years) PSA failure and, therefore, may benefit from the use of adjuvant therapy.

Abstract
PURPOSE Ideal candidates for 3D dose escalation conformal radiation or external beam + implant therapy are identified on the basis of the prostate-specific antigen (PSA) level, biopsy Gleason score, and the 1992 American Joint Commission Cancer (AJCC) clinical T-stage. METHODS AND MATERIALS The pathologic findings of 1742 men with clinical stage T1c,2 prostate cancer managed with a radical prostatectomy (RP) between 1990 and 1998 were subjected to a logistic regression multivariable analysis. The endpoints examined included pathologic organ-confined (OC), specimen-confined (SC), and margin (M) or seminal vesicle (SV) positive disease. SC disease was defined as extracapsular extension (ECE) with a negative surgical margin. The clinical factors tested included PSA level, biopsy Gleason score, and the 1992 AJCC clinical T-stage. PSA failure-free (bNED) survival was calculated according to the method of Kaplan and Meier. RESULTS Significant negative predictors of pathologic OC-disease or positive predictors of M+ or SV+ disease included a PSA > 10 ng/ml (p<0.0001), biopsy Gleason score < or =7 (p< or =0.0004), and > or =T2b disease (p< or =0.03). Only biopsy Gleason score 7 (p = 0.0006) and PSA 10-15 ng/ml (p = 0.04) were significant predictors of SC disease. The estimates of 5-year bNED survival were 80%, 62%, and 35% (p<0.0001) for patients having a low, intermediate, or high likelihood of having M+ or SV+ disease respectively. CONCLUSIONS Patients most likely to derive a survival benefit from the improved local control possible using dose escalation techniques were those who had both a low risk of having occult micrometastatic disease (<25% M+ or SV+) and a reasonable likelihood of remaining disease-free after RP (>50% 5-year bNED). These patients included those having T1c, 2a, PSA > 10-15 ng/ml, and biopsy Gleason < or =6 or T1c, 2a, 2b, PSA < or =10 ng/ml, and biopsy Gleason < or =7 prostate cancer.

Abstract
PURPOSE This study was performed to determine the ability of the biopsy Gleason score, prostate-specific antigen (PSA) level, and the 1992 American Joint Commission on Cancer (AJCC) clinical T-stage for predicting time to postoperative PSA failure for patients with a PSA < or =10 ng/ml and T1c or T2a disease. Specific attention is given to the patient subgroup with biopsy Gleason 3 + 4 vs. 4 + 3. METHODS AND MATERIALS A concordance map of the biopsy and prostatectomy Gleason grades and a clinical-pathologic correlation of the PSA, biopsy Gleason score, and 1992 AJCC T-stage and pathologic stage were performed. A Cox regression multivariable analysis was used to evaluate the ability of the biopsy Gleason score, PSA, and 1992 AJCC T-stage to predict time to PSA failure for 457 men managed with a radical prostatectomy (RP). RESULTS The absence of prostatectomy Gleason grade 4 or 5 disease was noted in 71%, 50%, and 11% of patients with biopsy Gleason score 2-6, 3 + 4, and > or =4 + 3 disease respectively while pathologic evidence of seminal vesicle invasion was noted in 2%, 4%, and 17% of these patients respectively. Estimates of 5-year PSA failure-free survival rates were not statistically different for patients with biopsy Gleason score 2-6 vs. 3 + 4 (79% vs. 81%; p = 0.93), but were significantly different for patients having biopsy Gleason score 2-6 vs. 4 + 3 (79% vs. 62%; p = 0.04) or 2-6 vs. 8-10 (79% vs. 18%; p = 0.0001) prostate cancer. CONCLUSION Based on the pathologic stage and PSA control data following RP, patients with biopsy Gleason 3 + 4 disease and PSA < or =10 ng/ml and 1992 AJCC T1c or T2a disease may be suitable candidates for radiation therapy directed at the prostate only.

Abstract
PURPOSE A survival benefit has been suggested by the Radiation Therapy Oncology Group (RTOG) for the addition of androgen suppression to external beam radiation therapy for patients with locally advanced and high-grade disease. This study was performed to identify clinical factors that predicted high-grade disease at prostatectomy (i.e., Gleason grade 4 or 5) in patients with clinically localized and low-grade disease (i.e., Gleason grades 1-3) at biopsy. These pretreatment factors may allow for the identification of patients likely to derive a survival benefit from the addition of androgen suppression to external beam radiation therapy while awaiting the results of the prospective randomized trials. METHODS AND MATERIALS Concordance testing of both the primary and secondary biopsy and prostatectomy Gleason grades was performed in 693 patients with clinical Stage T1c, 2 prostate cancer managed with a radical prostatectomy (RP). For the subset of 420 patients with low-grade disease (i.e., Gleason grade < or =3) a logistic regression multivariable analysis was performed to evaluate the ability of the preoperative prostate-specific antigen (PSA), clinical stage, and ultrasound determined prostate gland volume to predict for upgrading to high-grade disease (i.e., Gleason grade 4 or 5). RESULTS Forty percent of men with low-grade disease at biopsy were found to have high-grade disease at RP. Men who have at least a 50% chance of being upgraded from biopsy Gleason grade < or =3 to prostatectomy Gleason grade > or =4 disease included those with prostate gland volumes < or =75 cm3 and a PSA > 20 ng/ml or a PSA >10 and < or =20 and clinical Stage T2b,2c. For men with prostate gland volumes >75 cm3, only those with both PSA > 20 ng/ml and clinical Stage T2b,2c were at a significant risk of upgrading. CONCLUSION Until the randomized data become available, clinical factors may be useful in identifying patients with clinically localized prostate cancer who are likely to benefit from combined androgen suppression and external beam radiation therapy.

Abstract
The radiation safety system of the B-Factory accelerator facility at the Stanford Linear Accelerator Center is described. The radiation safety system, which is designed to protect people from prompt radiation exposure due to beam operation, consists of the access control system and the radiation containment system. The access control system prevents people from being exposed to the very high radiation levels inside a beamline shielding enclosure. The access control system consists of barriers, a standard entry module at every entrance, and beam stoppers. The radiation containment system prevents people from being exposed to the radiation outside a shielding enclosure due to either normal or abnormal operation. The radiation containment system consists of power limiting devices, shielding, dump and collimator, and an active radiation monitoring system. The inter-related elements for the access control system and radiation containment system, as well as the associated interlock network, are described. The policies and practices used in establishing the radiation safety system are also compared with the regulatory requirements.
