Abstract
PURPOSE/OBJECTIVE(S) For patients with soft tissue sarcoma (STS) who cannot or choose not to have surgery, radiation can provide local tumor control in both palliative and definitive settings. Conventionally fractionated radiation provides modest (< 50%) rates of local control (LC) for STS at 2 years. To our knowledge, no prospective studies to date have evaluated the safety and efficacy of dose-escalated hypofractionated radiation therapy as treatment of inoperable STS. We hypothesized that dose-escalated, hypofractionated radiation therapy (RT) for inoperable STS could achieve higher rates of LC than reported in trials of conventionally fractionated RT. MATERIALS/METHODS An IRB-approved single institution prospective phase II clinical trial of dose-escalated, hypofractionated RT as local control for STS was designed and completed planned accrual. Exclusion criteria included anti-cancer systemic therapy within the preceding two weeks. Patients underwent hypofractionated RT utilizing either CT-guided radiation (24, 50%) or MRI-guided radiation treatments (24, 50%). Data on patient characteristics, RT dose and fractionation, LC, toxicity, and overall survival (OS) was collected. The primary endpoint was local tumor control (stable, partial, or complete response according to RECIST) at 2-years after completion of radiation. Secondary endpoints were acute and late toxicity, rates of complete response, 5-year local tumor control, and progression-free and overall survival. Acute toxicity was graded on the Common Terminology Criteria for Adverse Events (CTCAE) v5.0 scale during treatment and at 3 months following RT. RESULTS Forty-eight patients were enrolled, 17 with non-metastatic localized disease and 31 with metastatic disease. Median patient age was 64. Twenty-five men and 23 women were treated. Ninety-six total lesions were treated (36 lung, 7 extremity, 37 abdominopelvic, 16 other). Radiation dose per fraction ranged from 6-12 Gy for a total of 1-12 fractions (median dose was 52.5 Gy in 6 fractions. Median patient follow-up is 8.6 months (range 1 - 36 months). Six patients (13%) did not complete initial 3-month follow-up imaging. Of the 40 patients who have undergone 3-month follow up imaging, 32 (80%) had stable disease, 5 (12.5%) had partial response, 0 had complete response, and 3 (7.5%) had disease progression. Median PFS was 17.2 months at time of last follow up. Median OS was 12.9 months at time of last follow up. Twenty-five patients (52%) experienced an acute toxicity likely or possibly related to radiation. Three (6%) patients experienced CTACE grade 3 or greater treatment-related toxicity (pain, weakness, decreased range of motion, dermatitis). CONCLUSION In this initial report of a prospective, single-institution clinical trial of hypofractionated RT for STS not undergoing resection, we report low rates of acute grade 3 or greater toxicity and high rates of tumor response. We will continue to follow these patients to assess late toxicity and durability of tumor control.

Abstract
Aggression is a behavior common in most species; it is controlled by internal and external drivers, including hormones, environmental cues, and social interactions, and underlying pathways are understood in a broad range of species. To date, though, effects of gut microbiota on aggression in the context of gut-brain communication and social behavior have not been completely elucidated. We examine how manipulation of Drosophila melanogaster microbiota affects aggression as well as the pathways that underlie the behavior in this species. Male flies treated with antibiotics exhibited significantly more aggressive behaviors. Furthermore, they had higher levels of cVA and (Z)-9 Tricosene, pheromones associated with aggression in flies, as well as higher expression of the relevant pheromone receptors and transporters OR67d, OR83b, GR32a, and LUSH. These findings suggest that aggressive behavior is, at least in part, mediated by bacterial species in flies. Aggression increases in flies that lack a microbiome Monocolonization with specific bacteria can mediate this effect We observed differences in aggression-related pheromone expression levels

Abstract
INTRODUCTION Pathologic complete response (pCR) after neoadjuvant chemotherapy has a demonstrated survival advantage; however, outcomes for non-pCR by receptor status are less understood. We sought to evaluate survival and distant recurrence by receptor status for patients with residual stage II/III breast cancer. METHODS A stage-stratified random sample of 11,366 patients with stage II-III breast cancer in 2006-2007 was selected from 1217 facilities in the National Cancer Database for a Commission on Cancer Special Study. We identified patients with residual pathologic stage II/III cancer who received standard of care therapy based on receptor status. Distant recurrence and 5-year survival were abstracted and Kaplan-Meier curves were generated by receptor status. Multivariable Cox regression was used to estimate hazard ratios for death and distant recurrence. RESULTS A total of 734 patients had residual disease; 58%, 28%, and 14% were ER or PR+/Her2neu-, ER and PR-/Her2neu-, and Her2neu+ (any ER/PR), respectively. ER and PR-/Her2neu- cancers had the poorest 5-year overall (52% vs. 82% for Her2neu+ and ER or PR+/Her2neu-, p < 0.0001) and distant recurrence-free survival (57% vs. 72% Her2neu+ and 77% ER or PR+/Her2neu, p < 0.0001). Cox regression models demonstrated a higher likelihood of distant recurrence and death for patients with ER and PR-/Her2neu- disease (HR 2.25, 95% CI 1.56-3.24 and HR 3.19, 95% CI 2.20-4.64 respectively) compared with ER or PR+/Her2neu-. CONCLUSIONS Patients with residual ER and PR-/Her2neu- cancer have a significant risk of distant recurrence and mortality compared with other breast cancer types, supporting the consideration for additional adjuvant therapy and novel clinical trials in this cohort. Trial registry number ClinicalTrials.gov identifier NCT02171078.

Abstract
BACKGROUND Successful breast-conserving surgery requires achieving negative margins. At our institution, the whole surgical specimen is imaged and then serially sectioned with repeat imaging. A multidisciplinary discussion then determines need for excision of additional margins. The goal of this study was to determine the benefit of each component of this approach in reducing the number of positive margin. METHODS This single-institution, prospective study included ten breast surgical oncologists who were surveyed to ascertain whether they would have taken additional margins based their review of whole specimen images (WSI) and review of serially sectioned images (SSI). These results were compared with the multidisciplinary decisions (MDD) and pathology results. Margin status was defined using consensus guidelines. RESULTS One hundred surveys were completed. Margins on the original specimen were positive or close in 21%. After WSI, surgeons reported that they would have taken additional margins in 26 cases, reducing the number of positive/close margins from 21 to 13% (p < 0.001). After SSI, 52 would have taken additional margins; however, the number of positive/close margins remained 13%. MDD resulted in additional margins taken in 56 cases, reducing the number of positive/close margins to 7% (p < 0.001 compared with SSI). CONCLUSIONS While surgeon review of specimen radiographs can decrease the number of positive or close margins from 21 to 13%, more rigorous multidisciplinary, intraoperative margin assessment reduces the number of close or positive margins to 7%.

Abstract
BACKGROUND There is concern that elders are not adequately evaluated prior to colon cancer surgery. We sought to determine adherence with ACOVE-3 (Assessing Care of Vulnerable Elders) quality indicators for pre-operative staging prior to colectomy for colon cancer utilizing the Surveillance, Epidemiology and End Results (SEER)-Medicare linked database (1992-2005). METHODS We determined the proportion of patients aged 75 and older who had preoperative staging prior to colectomy for colon adenocarcinoma. Preoperative staging was defined as abdominopelvic computed tomography or magnetic resonance imaging scan (SCAN) and colonoscopy or flexible sigmoidoscopy (SCOPE). Multivariate logistic regression identified predictors of adherence. Odds ratios were adjusted for comorbidity, socioeconomic status, and disease severity. The association of adherence to ACOVE-3 and survival was quantified. RESULTS Of the 37,862 patients, the majority were 75-84 years, 28% of the patients were ≥85 years. Regarding preoperative staging in the 6-month interval prior to surgical resection, 8% had neither SCAN nor SCOPE, 6% had only SCAN, 43% had only SCOPE, and 43% had both SCAN and SCOPE. Compared to patients who were not staged, those evaluated with either SCOPE alone or SCAN plus SCOPE had lower odds of 3-year mortality. Patients who were staged with SCAN alone had an increased odds of death compared to those who had neither SCAN or SCOPE. CONCLUSIONS These data demonstrate that the majority of vulnerable elders with colon cancer did not receive appropriate preoperative staging prior to resection. The findings also confirm that adherence to ACOVE-3 guidelines is associated with improved long-term survival.

Abstract
Abstract
Background: Inheritance of an abnormal BRCA 1/2 gene, a family history of breast cancer (BrCa), or a personal history of lobular carcinoma in situ (LCIS), atypical hyperplasia, or chest wall radiation can significantly increase an individual's lifetime risk for developing BrCa. In 2007, the American Cancer Society (ACS) released updated guidelines for screening in women with a lifetime risk of BrCa ≥20-25%. These guidelines added MRI screening to annual mammography. The objective of our analysis is to characterize patients referred after the release of the 2007 ACS guidelines to subspecialty providers specifically for evaluation of BrCa risk and analyze subsequent screening and risk reduction recommendations in the cohort of patients (pts) with a predicted increased lifetime risk for BrCa.
Methods: Pts seen at a single center (University of Wisconsin [UW]) between 1/2007-3/2011 by medical, surgical and/or gynecology-oncology for an increased lifetime risk of BrCa were identified by billing codes or evaluation in the UW Breast Cancer Prevention, Assessment and Tailored Health Screening (PATHS) Clinic. Pts with a personal history of BrCa prior to 1/2007 are excluded. Patients with a known genetic predisposition to BrCa, family history of breast cancer, or a personal history of LCIS, atypical hyperplasia or chest wall radiation are included in this analysis. All charts will be evaluated for documentation of the individual's lifetime risk of BrCa and method used for risk-assessment, recommended and performed screening tests, concordance with ACS screening guidelines, patient adherence to initial and subsequent screening recommendations, and uptake of risk reduction strategies. Call-back rates for additional or follow-up imaging and/or biopsy following BrCa screening and characteristics of all new BrCa diagnoses will be collected.
Results: 240 eligible pts were seen during the study period. 15% of pts referred had a known genetic predisposition to BrCa. Most pts (75%) were referred for a family history of BrCa. The majority of these pts had a predicted lifetime risk of BrCa in excess of 20%, with less than 10% of patients being referred having a lifetime risk <20%. The remaining pts were referred for a personal history of LCIS, atypical hyperplasia or previous radiation to the chest wall. Results including subspecialty provider BrCa risk assessment, screening and risk-reduction recommendations, patient uptake and adherence, outcomes of screening and characteristics of diagnosed BrCa cases will be presented.
Conclusion: Pts with a predicted increased lifetime risk for BrCa are often evaluated by oncology subspecialty providers. The primary factor related to referral is family history of BrCa. The majority of patients referred to a subspecialty provider have a calculated lifetime risk for BrCa in excess of 20%. This study evaluates provider assessment of BrCa risk and subsequent recommendations for screening and discussion of risk reduction strategies.

Abstract
8517 Background: We sought to validate the AJCC staging system for stage IV melanoma in a contemporary, prospective, single- institution cohort and explore additional clinical factors that may influence prognosis. Methods: A prospective institutional database identified 1319 patients with stage IV melanoma. To minimize tertiary center referral bias, only patients seen prior to a stage IV diagnosis were included (n=687). Variables were dichotomized: lactate dehydrogenase (LDH) (=200, >200), number of metastases (1, >1), and number of involved organs (1, >1). Kaplan-Meier curves were generated and Cox regression was used to identify factors independently predictive of survival. Results: Demographics are provided in the table . The median age at diagnosis of stage IV was 55 years (range 16–94) and the median disease free interval (DFI) was 12 months (0–181). The overall median survival was 10 months (5–21) with a median follow-up for survivors of 31 months (9–68); 569 deaths were observed. Cox regression analysis ( table ) identified younger age at stage IV diagnosis, a longer DFI, and a normal LDH to be predictive of improved survival. Patients with either distant skin/subcutaneous/nodal or pulmonary disease experienced prolonged survival when compared to patients with metastases to other visceral sites. Survival was improved in patients with a single metastatic site at diagnosis of stage IV. Gender, antecedent stage, and number of involved organs were not associated with outcome. Conclusions: In this single institution cohort of patients with stage IV melanoma, poorer survival in patients with non-pulmonary visceral metastases and/or abnormal LDH levels as described by the AJCC staging system was confirmed. Additionally, the number of metastases at the time of diagnosis of stage IV was the most powerful predictor of poorer survival and may be a variable to consider in future staging systems. No significant financial relationships to disclose. [Table: see text]

Abstract
Bacterial meningitis is an important acute infectious disease of childhood that remains a source of substantial morbidity and mortality. The impact of the Haemophilus influenzae type b (HIB) conjugate vaccines on the epidemiology of the other bacterial causes of meningitis in childhood has received little attention. The objective of this study is to report the experience at a tertiary-care children's hospital with the occurrence of bacterial meningitis before and after the licensure of the HIB conjugate vaccine. With use of International Classification of Diseases diagnostic codes for bacterial meningitis, a list of all children admitted to Children's Hospital of Pittsburgh with a primary or secondary diagnosis of meningitis due to H. influenzae, Streptococcus pneumoniae, and Neisseria meningitidis from January 1, 1988, to December 31, 1998, was constructed. Medical records were examined for basic patient demographic information including age, gender, race, bacterial etiology of meningitis, receipt of vaccine for HIB, underlying conditions, and fatalities. Two hundred twenty-one cases of bacterial meningitis caused by H. influenzae, N. meningitidis, and S. pneumoniae were identified. The age of infected children ranged from 1 month to 18 years, with a mean and median age of 38.1 months and 13 months, respectively. Fifty-two percent of the children were female, 83% were Caucasian and 16% were African-American. Before the routine use of HIB conjugate vaccine, HIB was the bacterial species responsible for the greatest proportion of cases (average of 58%/year). The absolute number of cases of bacterial meningitis attributable to HIB declined after 1991 to an average of 2.5 cases/year. The number of cases of meningitis caused by S. pneumoniae and N. meningitidis have remained relatively stable between 1988 and 1998. The case fatality rates for children with meningitis caused by H. influenzae, S. pneumoniae, and N. meningitidis were 0.0%, 9.2%, and 7.5%, respectively. Most cases of meningitis due to HIB occurred in children who had not been immunized. Three children who received the polysaccharide vaccine developed meningitis due to HIB; there were no failures of the conjugate vaccine.

Abstract
The traditional treatment of acute colonic obstruction, usually caused by malignant tumor, is a 2-stage surgical procedure. The first operation is emergent and includes primary tumor resection and end colostomy followed by scheduled colostomy closure. These operations are associated with high mortality and morbidity. Recently, insertion of self-expanding metallic stents for temporary colonic decompression has been was introduced. With this new technique colostomy can be avoided in the acute phase. In advanced colonic cancer stent-insertion is the only palliative treatment. It is done in the radiology department under fluoroscopic guidance. We present 2 cases of malignant colonic obstruction treated successfully by stent insertion.

Abstract
The effect of high-speed dental turbines on dentists' hearing was investigated. The two types of dental turbines used most commonly in the Tel Aviv area and their average time of daily use were established by means of questionnaires. The noise pressure level of these turbines at a distance of 30.0 cm was measured. Twenty subjects were exposed to the turbine noise for a period equal to the average time of the drill's daily use. The noise pressure levels of the turbines were found to be nonhazardous by the accepted damage-risk criteria. The temporary threshold shifts of the subjects exposed were nil or insignificant. It was concluded that the risk of damage to the dentist's hearing due to dental turbine noise in the normal course of a working day is slight.
