Abstract Background Treatment for locally advanced oesophagogastric adenocarcinoma (OGA) involves neoadjuvant chemotherapy (NAC) which has a negative impact on patient fitness. Using ‘prehabilitation’ to increase activity levels and fitness may affect physiology, postoperative outcomes and improve patient wellbeing and quality of life. The aim of this study was to evaluate feasibility, acceptability and the impact of a home-based structured prehabilitation programme in OGA. Methods This feasibility study recruited consecutive patients to a pragmatic home-based prehabilitation during NAC. Participants completed daily walking sessions to a targeted step-count and daily strengthening exercises, under the weekly supervision of the research team. The primary outcomes assessed feasibility through recruitment rate, completion rate and individual compliance with each component of the intervention. Secondary outcomes included fitness derived from cardiopulmonary exercise testing (CPET). Results A total of 42/58(72%) patients approached were recruited, 36/39(92%) patients completed the programme. Median compliance with wearing a pedometer and recording step count was 97.8%(IQR 93.2-100%) and median engagement with telephone contacts was 100%(IQR 93.1-100%). Median compliance with 30-minutes aerobic exercise was 70.2%(IQR 53.1-88.9%) and for strength exercises 69.4%(IQR 52.1-84.3%). Nineteen patients had pre and post intervention CPET with no significant difference in anaerobic threshold (mean difference -0.5 ml.kg-1.min-1, 95% CI -1.6 to + 0.6, p = 0.387) or VO2peak (mean difference -0.1 ml.kg-1.min-1, 95% CI -1.6 to + 1.4, p = 0.883). Conclusions This study shows that ChemoFit is feasible, safe and achieved excellent patient compliance and engagement. Future utilisation of this home-based prehabilitation programme may improve preoperative fitness during NAC and impact post-operative outcomes.

15077 Background: Growth of esophageal cancer involves a proliferative hemangiogenic component. Biomarkers that predict this propensity in esophageal cancer and the impact of anti-angiogenic strategy on their levels as well as clinical response remain unknown. Methods: A multimodular approach was devised to assess hemangiogenic parameters in a cohort of chemotherapy naïve patients with locally advanced (T2-T3N0, T1-T3N1M0M1a) esophageal cancer pre- and 4 days post-celecoxib neoadjuvant treatment. Patients went on to receive neoadjuvant therapy with celecoxib, paclitaxel and carboplatin for 3 cycles, followed by surgical resection. This bioassay panel consists of 5 components: i) HUVEC-based angiogenic scale for functional plasma angiogenic activity, ii) flow cytometry to quantify CD133+VEGFR2+ circulating endothelial progenitors (CEPs), iii) hematopoietic colony-forming assay to quantify circulating hematopoietic progenitors (CHPs), iv) plasma SDF-1 level, and v) platelet VEGF-A level. Results: The cohort consists of 8 consecutive patients (6 men, 2 women) with median age of 58. After 18 months of followup, 6 patients remained alive and without evidence of recurrence, while 2 had tumor recurrence and metastasis. Analysis of the positive responders (pre-celecoxib baseline versus 4 days post treatment) revealed a global suppression of hemangiogenic parameters with reduction of the functional HUVEC-based angiogenic scale (mean score of 3.3 versus 1.8; p<0.05), 2.2-fold decrease in CEPs (p<0.05), and 3-fold decrease in CHPs (p<0.05). This trend also correlated with decreased plasma SDF-1 and platelet VEGF-A levels . However, in the 2 cases of tumor recurrence, the initial hemangiogenic response was blunted with no significant difference in all parameters tested during the celecoxib monotherapy period. Conclusion: Esophageal cancer development involved a hemangiogenic switch toward increased CEPs, CHPs, and functional plasma pro-angiogenic activity. COX2 inhibition with celecoxib normalized the hemangiogenic profile. Collective assessment of hemangiogenic biomarkers during neoadjuvant setting may be a promising tool in predicting clinical outcomes, recurrence, and for validating impact of anti-angiogenic therapy on esophageal cancer.

Abstract Background Oesophageal cancer incidence has increased over the last decade in the UK, particularly in older patients. Surgery, with or without perioperative chemotherapy, remains the gold standard treatment for patients with potentially curable disease. Currently, 41% of new cases of oesophageal cancer are in patients aged over 70. However, only 10% underwent surgery compared to 25% of those aged under 70. Concerns exist that advanced age may prejudice treatment decisions. The aim of our review is to evaluate the impact of age on outcomes in those undergoing planned curative treatment for oesophageal cancer. Methods A retrospective review of patients undergoing oesophagectomy for carcinoma between 2006 to 2016 at a single institution was performed. Patients were divided into two cohorts based on age at the time of diagnosis; under 70 years (Group A) and over 70 (Group B). Patients underwent a standardised staging protocol and treatment was decided by a multi-disciplinary team. Oesophagectomy was performed using a transthoracic approach with two field lymphadenectomy and perioperative chemo (radio) therapy used in those patients with locally advanced disease who were fit enough. Results There were 555 patients in Group A and 241 in Group B. Adenocarcinoma was the prevalent histological subtype in both cohorts: 76% (423) in Group A and 68% (165) in Group B. Median age at the time of diagnosis was 62 in Group A versus 74 in Group B. In Group A, 12% (18/343) did not receive neo-adjuvant treatment for locally advanced cancer versus 47% (101/212) in Group B (P < 0.001). Median hospital stay was longer in Group B (18 v 15 days P = 0.02). There was no significant difference in hospital mortality (Group A 1% vs Group B 2.4% P = 0.37) and major complication rate (Group A 14% vs Group B 20% P = 0.31). Two-year survival was 66% (adenocarcinoma) and 78% (SCC) in Group A compared to 60% (adenocarcinoma) and 64% (SCC) in Group B. Conclusion These results demonstrate that patients over 70 can be treated successfully with minimal additional risk to morbidity and mortality. However, these patients are more likely to be denied neoadjuvant treatment which may compromise their long-term outcomes. Disclosure All authors have declared no conflicts of interest.

Abstract Objectives Neoadjuvant chemoradiation (nCRT) is universally considered to be a valid treatment to achieve downstaging, to improve local disease control and to obtain better resectability in locally advanced rectal cancer (LARC). The aim of this study is to correlate the change in the tumour 18F-FDG PET-CT standardized uptake value (SUV) before and after nCRT, in order to obtain an early prediction of the pathologic response (pR) achieved in patients with LARC. Data description We performed a retrospective analysis of patients with LARC diagnosis who underwent curative resection. All patients underwent a baseline 18F-FDG PET-CT scan within the week prior to the initiation of the treatment (PET-CT SUV1) and a second scan (PET-CT SUV2) within 6 weeks of the completion of nCRT. We evaluated the prognostic value of 18F-FDG PET-CT in terms of disease-free survival (DFS) and overall survival (OS) in patients with LARC.A total of 133 patients with LARC were included in the study. Patients were divided in two groups according to the TRG (tumour regression grade): 107 (80%) as the responders group (TRG0-TRG1) and 26 (25%) as the no-responders group (TRG2-TRG3). We obtained a significant difference in Δ%SUV between the two different groups; responders versus no-responders (p < 0.012). The results of this analysis show that 18F-FDG PET-CT may be an indicator to evaluate the pR to nCRT in patients with LARC. The decrease in 18F-FDG PET-CT uptake in the primary tumour may offer important information in order for an early identification of those patients more likely to obtain a pCR to nCRT and to predict those who are unlikely to significantly regress.

Background In El Salvador, over 32% of all deaths are due to trauma. However, El Salvador lacks any established standardized trauma response system to treat the most critical of Salvadoran patients. In an effort to improve trauma response in El Salvador, we assessed the impact of a trauma-specific skills training, which could improve trauma care in a setting where no formal trauma training exists. Methods We used a pre- and post-interventional design study to measure the critical actions performed during a trauma event, as well as the case-fatality rate, emergency ward-to-operating room time, and utilization of ultrasound. The intervention was a primary trauma care course taught to all study participants. Results Eighteen providers were observed over a six-month period and 194 patient encounters (48 pre- and 146 post-intervention) were recorded. There was no significant difference in observed critical actions during major trauma between the pre-intervention and post-intervention periods. There was a significant improvement in ultrasound usage post-intervention (9.5% to 21.4%; p = 0.04). Conclusion The lack of behavior change observed following a two-day trauma training underscores the gap between physician knowledge and applied behavior change. This is a limited single center study, but further examination is necessary to determine the role of two-day training courses in the larger context of behavior change within a health system that has no formal post-graduate training in or defined algorithmic trauma care.

OBJECTIVES: to compare the impact of mastectomy and conservative surgery on the quality of life of patients with breast cancer. METHODS: an assessment was made of the quality of life of patients undergoing mastectomy or segmentary mastectomy, at the Pouso Alegre Clinical Hospital, in the Brazilian State of Minas Gerais, using SF-36. The patients were grouped by age (<50 years and >50 years) and years of schooling (<8 years and >8 years). The Mann-Whitney test was used to compare the groups with regard to the age and schooling domains of SF-36. RESULTS: a significant difference between the two groups was found in the domains of "physical functioning" (p=0.04) and "pain" (p=0.01): with the patients undergoing a mastectomy registering the worst scores. Young patients who had undergone a mastectomy displayed the worst quality of life in terms of "physical functioning" (p=0.03), "pain" (p=0.01) and "social functioning" (p=0.01); those undergoing conservative surgery aged over 50 years scored worst on "role emotional" (p=0.05). Patients undergoing a mastectomy with lower levels of schooling scored lower in "physical functioning" (p=0.01), "role physical" (p=0.05) and "pain" (p=0.05). Among those who had attended school for more than eight years, those having undergone a mastectomy scored less in the "pain" domain (p=0.04). CONCLUSIONS: patients who had undergone a mastectomy had worse results in the physical component of the evaluation of quality of life and this negative impact was more strongly felt among younger patients and those with lower levels of schooling.

Abstract Background In Germany a new reimbursement system for psychiatric clinics was proposed in 2009 based on the § 17d KHG Psych-Entgeltsystem. The system can be voluntary implemented by clinics since 2013 but therapists are frequently afraid it might affect treatment negatively. Objectives To evaluate whether the new system has a negative impact on treatment success by analysing routinely collected data in a Bavarian clinic. Material and methods Aggregated data of 1760 patients treated in the years 2007–2016 was analysed with segmented regression analysis of interrupted time series to assess the effects of the system on treatment success, operationalized with three outcome variables. A negative change in level after a lag period was hypothesized. The robustness of results was tested by sensitivity analyses. Results The percentage of patients with treatment success tends to increase after the new system but no significant change in level was observed. The sensitivity analyses corroborate results for 2 outcomes but when the intervention point was shifted, the positive change in level for the third outcome became significant. Conclusions Our initial hypothesis is not supported. However, the sensitivity analyses disclosed uncertainties and our study has limitations, such as a short observation time post intervention. Results are not generalizable as data of a single clinic was analysed. Nevertheless, we show the importance of collecting and analysing routine data to assess the impact of policy changes on patient outcomes.

Abstract Background Mobile health applications (mHealth apps) targeting physical inactivity have increased in popularity yet are usually limited by low engagement. This study examined the impact of adding team-based incentives (Step Together Challenges, STCs) to an existing mHealth app (Carrot Rewards) that rewarded individual physical activity achievements. Methods A 24-week quasi-experimental study (retrospective matched pairs design) was conducted in three Canadian provinces (pre-intervention: weeks 1–12; intervention: weeks 13–24). Participants who used Carrot Rewards and STCs (experimental group) were matched with those who used Carrot Rewards only (controls) on age, gender, province and baseline mean daily step count (±500 steps/d). Carrot Rewards users earned individual-level incentives (worth $0.04 CAD) each day they reached a personalized daily step goal. With a single partner, STC users could earn team incentives ($0.40 CAD) for collaboratively reaching individual daily step goals 10 times in seven days (e.g., Partner A completes four goals and Partner B completes six goals in a week). Results The main analysis included 61,170 users (mean age = 32 yrs.; % female = 64). Controlling for pre-intervention mean daily step count, a significant difference in intervention mean daily step count favoured the experimental group (p < 0.0001; ηp2 = 0.024). The estimated marginal mean group difference was 537 steps per day, or 3759 steps per week (about 40 walking min/wk). Linear regression suggested a dose-response relationship between the number of STCs completed (app engagement) and intervention mean daily step count (adjusted R2 = 0.699) with each new STC corresponding to approximately 200 more steps per day. Conclusion Despite an explosion of physical activity app interest, low engagement leading to small or no effects remains an industry hallmark. In this paper, we found that adding modest team-based incentives to the Carrot Rewards app increased mean daily step count, and importantly, app engagement moderated this effect. Others should consider novel small-teams based approaches to boost engagement and effects.

Abstract Omentectomy is conducted for advanced gastric cancer (AGC) patients as radical surgery without an adequate discussion of the effect. This study was conducted to reveal the impact of omentum-preserving gastrectomy on postoperative outcomes. AGC patients with cT3 and 4 disease who underwent total or distal gastrectomy with R0 resection were identified retrospectively. They were divided into the omentum-preserved group (OPG) and the omentum-resected group (ORG) and matched with propensity score matching with multiple imputation for missing values. Three-year overall survival (OS) and 3-year relapse-free survival (RFS) were compared, and the first recurrence site and complications were analysed. The numbers of eligible patients were 94 in the OPG and 144 in the ORG, and after matching, the number was 73 in each group. No significant difference was found in the 3-year OS rate (OPG: 78.9 vs. ORG: 78.9, P = 0.54) or the 3-year RFS rate (OPG: 77.8 vs. ORG: 68.2, P = 0.24). The proportions of peritoneal carcinomatosis and peritoneal dissemination as the first recurrence site and the rate and severity of complications were similar in the two groups. Omentectomy is not required for radical gastrectomy for AGC.

AbstractCaudal autotomy, the self-induced tail shedding from the body, is a common defensive strategy in lizards. Tail loss is followed rapidly by regeneration, revealing the importance of a fully functional tail. Predation pressure has been traditionally correlated with autotomy performance. However there is a lack of evidence regarding the impact of predation regime on tail regeneration. Another important factor that has been neglected is the population density. Though it is well established that crowding alters various life-history traits, the impact of density on caudal regeneration remains understudied. In this paper we compared three island populations of the Aegean Wall Lizard (Podarcis erhardii) that have evolved under different levels of predation pressure: whereas the Naxos population is exposed to numerous predators the Kopries and Daskalio islet populations experience low predation pressure. To evaluate the effect of density-induced stress on caudal regeneration, lizards were treated under two conditions of housing, in single and crowded (six individuals) terraria. Tail sheding occurred prior to this treatment following a standardised method. The length of regenerated tail was recorded weekly. Regeneration rate was higher in single terraria when compared to crowded, reflecting the negative impact of crowding. However we failed to detect any statistically significant difference between single and crowded terraria in the case of Naxos. We believe that the underlying reason must be the heavy predation pressure under which rapid tail regeneration, even under unfavourable conditions, is crucial for survival. It seems that the imperious need for regeneration counteracts density-induced stress.
