14536 Background: The role of metastatic site in MCCID is unclear. The goal of this study is to evaluate if metastatic site influence survival in this setting of patients (P). Methods: Analyses were based on individual data of 300 P with MCCID treated with biochemical modulation of 5- Fluorouracil by Methotrexate regimens in different prospective trials conducted at GOCS Institutions since May 1984 to Aug 2000. P with surgical resection of liver metastases were not included in the analyses. 38 P were excluded for incomplete data. P were grouped according to metastatic sites into group A= Liver metastases only (n=161), group B= Liver and other metastatic sites (n=61) and group C= Non liver metastases (n=40) (lung, peritoneal, others). Different prognostic variables were considered: age, sex, PS, weight loss, size of liver metastases, unilateral or bilateral liver involvement, number of liver metastases, histologic differentiation of primary tumor, location of primary tumor, lactate dehydrogenase, alkaline phosphatase, ALT, AST and hemoglobin. Overall survival (OS) was analyzed since date of diagnosis by means of Kaplan-Meier and the Log-rank test was used to assess the differences. Results: The average follow-up time was 14.4 months (0–73.4). Clinical, laboratory and tumor characteristics were similar among groups A, B and C respectively. However P in group A had bigger size of liver metastases, higher number of them and more bilateral liver involvement respect to group B (p=0.02, p=0.03, p=0.05 respectively). Median OS in group A=21.0 months, group B=13.1 months and group C=15 months (p= 0.02). Statistical difference in OS was observed between group A and group B (p= 0.015). No difference was observed between groups A plus B vs the heterogeneous group C (p= 0.83) Conclusions: P with liver only metastatic site had better prognosis respect to those with other coexisting site of metastases despite presenting higher tumor burden in the liver. No factors analysed in the study explaine this difference. The subset of P with liver only metastatic site would be considered as a distinctive group and deserve further molecular studies.

CRA1008 Background: Decision making on systemic treatment of women with metastatic breast cancer is based on features like estrogen receptor (ER), progesterone receptor (PgR), and HER2 status assessed on the primary tumor. We evaluated the concordance of receptor status between primary tumor and liver metastases (mts) and its impact on treatment choice. Methods: We retrospectively analyzed a database including ultrasound guided liver biopsies performed from 1995 to 2008. All tissue samples, both from primary tumor and liver mts, were analyzed for ER, PgR and HER2 status. Clinical and biological data were obtained from medical charts. Differences between proportions were evaluated using the Pearson chi-square test. Results: We identified 255 consecutive patients (pts) with matched primary and liver tissue samples. Median time from primary diagnosis to liver biopsy was 3.4 years (range 0-18.3 years). Changes in ER status were observed in 41/255 pts (16.0%). 16/58 pts (27.6%) changed from ER-negative to ER-positive and 25/197 pts (12.7%) changed from ER-positive to ER-negative (p=0.0066). Changes in PgR status were observed in 76/255 pts (29.8%). 18/91 pts (19.8%) changed from PgR-negative to -positive and 58/164 pts (64.6%) from PgR-positive to PgR-negative (p <0.0001). 12/52 pts (23.1%) changed from ER- and PgR-negative to ER- or PgR-positive (group A) and 27/203 pts (13.3%) changed from ER- or PgR-positive to ER- and PgR-negative (group B) (p=0.087). In the group A the treatment of 4/12 pts (33.3%) was changed after biopsy: 2/4 started endocrine treatment (HT) and 2/4 stopped it. In group B the treatment of 18/27 pts (66.6%) was changed after biopsy: 17/18 stopped HT. Changes in HER2 status were observed in 22/167 pts (13.1%): 6/116 pts (5.1%) changed from HER2-negative to HER2-positive and 16/51 pts (31.4%) changed from HER2-positive to negative (p≤0.0001). In this group pts started and/or stopped a trastuzumab containing treatment after biopsy. Conclusions: There was a discordance in receptor status between primary tumor and liver mts, which led to change in therapy for 48/255 of pts (18.8%). Biopsy of metastases for reassessment of biological features should be considered in all pts when safe and easy to perform, since it is likely to impact treatment choice.

Background & Purpose: In patients with embolic stroke of undetermined source, aortic arch atheroma evaluated using transesophageal echocardiography (TEE) is a possible embolic source. We investigated the impact of embolic sources including aortic arch atheroma for a stroke recurrences and death. Methods: Among the consecutive 1545 acute stroke patients, 542 patients who were admitted within 24 hours after the symptom onset, with ischemic lesions in the cortex or cerebellum on the diffusion-weighted image, NIH stroke scale of 7 or less, and prior modified Rankin scale (mRS) of 0 or 1 were included in the present study. All 542 patients underwent TEE to search for embolic sources. According to the categories of embolic sources, patients were classified into 4 groups: patients with severe aortic arch atheroma of 4mm or more in diameter (group A; n=167), patients with cardiogenic embolic sources such as atrial fibrillation or intracardiac thrombus (group C; n=93), patients with both factors as described above (group B; n=88), and other patients (group O; n=194). We followed them up for average period of 3.2 years, and investigated the frequency of stroke recurrences and death from any cause according to embolic sources. Results: Stroke recurrences were observed in 12.0% patients in group A, 11.8% patients in group C, 18.2% patients in group B, and 6.7% patients in group O respectively (p=0.0371). Stroke recurrences and death from any cause occurred in 14.4%, 15.1%, 21.6% and 6.7% patients respectively (p=0.0041). Kaplan-Meier curve analysis revealed a significant difference in the recurrence-free survival among the four groups (p=0.0076, log-rank test). Stroke recurrence was more frequent in group B than group C patients especially in the early phase from the onset. On COX proportional-hazards model analysis and diabetes mellitus (HR 1.73, p=0.0264) and aortic arch atheroma of 4mm or more (HR 1.86, p=0.0146) were significant predictors for stroke recurrences and death from any cause. Conclusions: Severe aortic arch atheroma can independently be associated with stroke recurrences and death, furthermore, a combination of aortic arch atheroma and cardiogenic embolic sources showed more frequent events than each of them alone.

Background Open aortic arch surgery is a complex cardiac surgical procedure. Aims We have reviewed the 10-year outcomes of elective surgery for aortic arch aneurysm in the Cardiac Surgery Department, Upper-Silesian Medical Center of the Medical University of Silesia. Methods The analysis includes all patients who underwent elective aortic arch surgery at our institution from January 2010 to December 2020. To assess the impact of the surgical learning curve the study population was divided into group A consisting of patients operated during the first 5 years, and group B, including patients operated during the subsequent 5 years. Both groups were compared with regard to baseline characteristics, scope of the surgery, operative and postoperative data as well as morbidity and mortality. Results Eighty-six elective aortic arch surgeries were performed during the analyzed period, including 25 patients (29%) in group A and 61 patients in group B (71%). The hemiarch procedure was more frequently performed in group A (17 patients, 68%) in comparison to group B (21 patients, 34%) (P=0.008). More procedures on the descending aorta were performed in group B (27 patients, 44%) than in group A (6 patients, 24%) (P=0.09). Stroke was recorded in 6 patients (20%) from group A and 5 patients (8.2%) from group B (P=0.002). Five-year survival was 60±9.8% for group A, and 81±6.2% for group B (log-rank test, P=0.003). Conclusions After completion of the learning curve, open aortic arch surgery is associated with acceptable early mortality, low incidence of stroke, and high 5-year survival rate.

Purpose Several studies suggest that surgical excision of the primary tumor improves survival among patients with stage IV breast cancer at diagnosis. Exclusive locoregional radiotherapy (LRR) is an alternative form of locoregional treatment (LRT) in this setting. We retrospectively studied the impact of LRT on the survival of breast cancer patients with synchronous metastases. Patients and Methods Among 18,753 breast cancer patients treated in our institution between 1980 and 2004, 598 patients (3.2%) had synchronous metastasis at diagnosis. Demographic data, tumor characteristics, metastatic sites, and treatments were prospectively recorded. The impact of LRT on overall survival (OS) was evaluated by multivariate analysis including known prognostic factors. Results Among 581 eligible patients, 320 received LRT (group A), and 261 received no LRT (group B). LRT consisted of exclusive LRR in 249 patients (78%), surgery of the primary tumor with adjuvant LRR in 41 patients (13%), and surgery alone in 30 patients (9%). With a median follow-up time of 39 months, the 3-year OS rates were 43.4% and 26.7% in group A and group B (P =.00002), respectively. The association between LRT and improved survival was particularly marked in women with visceral metastases. LRT was an independent prognostic factor in multivariate analysis (hazard ratio [HR] = 0.70; 95% CI, 0.58 to 0.85; P = .0002). The adjusted HR for late death (≥ 1 year) was 0.76 (95% CI, 0.61 to 0.96; P = .02). Conclusion In our experience, LRT, consisting mainly of exclusive LRR, was associated with improved survival in breast cancer patients with synchronous metastases. Exclusive LRR may thus represent an active alternative to surgery.

496 Background: There is a growing interest in local treatment for metastatic solid tumors. Recently, retrospective studies have reported the potential benefit of RLT to primary bladder cancer in pts with metastatic disease. We tested the impact of previous RLT in pts with mUC treated with ICI. Methods: Data from pts with mUC treated with ICI collected between May 2013 and May 2019 using a multi-institutional database was evaluated. Stratification was made according to previous RLT with ICI versus no RLT with ICI. We defined RLT as radical surgery (RS) or ≥50 Gy of radiotherapy (RT) delivered to the bladder. The X2 test was used to determine differences in rates. Overall survival (OS) between previous RLT plus ICI (group A) versus no RLT plus ICI (group B) generated using Kaplan-Meier method was compared by log-rank test. OS was calculated from the date of initiation of ICI to the date of death. Analyses were performed using SPSS v21. Results: A total of 115 pts with mUC were treated with ICI, 62 (53.9%) previously were treated with RS, 7(6.1%) RT and 46 (40%) no received RLT. ICI prescribed were atezolizumab (55.7%), pembrolizumab (16.5%), durvalumab (11.3%), durvalumab/tremelimumab (7.8%), nivolumab (5.2%) and avelumab (3.5%). The disease control rate (CR [6.9%] +PR [9.6%] +SD [14.1%]) was higher for pts with previous RLT compared to those pts who did not receive RLT (CR [3.2%] + PR [5.8%] + SD [6.4%](P=0.325). Median OS was 11.23 mo (95% CI; 6.02-16.44) and 7.95 mo (95%IC; 5.15-10.75) for group A and group B, respectively (P=0.481). Conclusions: This multicenter cohort suggests that previous RLT might play an impact for control disease in pts with mUC treated with ICI. Although this is hypothesis generating, the true value of this approach remains to be demonstrated in prospective studies.

Objective. The objective of this study was to investigate the impact of left atrial (LA) size for the ablation of atrial fibrillation (AF) using remote magnetic navigation (RMN). Methods. A total of 165 patients with AF who underwent catheter ablation using RMN were included. The patients were divided into two groups based on LA diameter. Eighty-three patients had small LA (diameter <40 mm; Group A), and 82 patients had a large LA (diameter ≥40 mm; Group B). Results. During mapping and ablation, X-ray time (37.0 (99.0) s vs. 12 (30.1) s, P<0.001) and X-ray dose (1.4 (2.7) gy·cm2 vs. 0.7 (2.1) gy·cm2, P=0.013) were significantly higher in Group A. No serious complications occurred in any of the patients. There was no statistical difference in the rate of first anatomical attempt of pulmonary vein isolation between the two groups (71.1% vs. 57.3%, P=0.065). However, compared with Group B, the rate of sinus rhythm was higher (77.1% vs. 58.5%, P<0.001) during the follow-up period. More patients in Group A required a sheath adjustment (47/83 vs. 21/82, P<0.001), presumably due to less magnets positioned outside of the sheath. In vitro experiments with the RMN catheter demonstrated that only one magnet exposed created the sheath affects which influenced the flexibility of the catheter. Conclusions. AF ablation using RMN is safe and effective in both small and large LA patients. Patients with small LA may pose a greater difficulty when using RMN which may be attributed to the fewer magnets beyond the sheath. As a result, the exposure of radiation was increased. This study found that having at least two magnets of the catheter positioned outside of the sheath can ensure an appropriate flexibility of the catheter.

Seniors are a constantly growing group of people in many societies. It is necessary to develop physiotherapeutic programs to improve their mobility. The aim of this study was to assess the impact of the physiotherapeutic program conducted unstable ground on selected indicators of motor functions of elderly women. Sixty women (60–80 years) participated in the research. Group A (N = 20) underwent a 12-week physiotherapeutic program on stable ground, group B (N = 20) followed an exercise program on unstable ground, and group C (N = 20) (control group) had no therapeutic intervention. The effects of the therapy were assessed by using a FreeMed platform (foot load analysis) and a Biosway balance system. The results were compared using ANOVA (the one-way analysis), the Kruskal–Wallis test and also the post hoc tests (Tukey’s test and the multiple comparison test). In group A, a statistically significant change was observed in the static test and balance assessment, in group B this was observed in the static and dynamic foot tests and balance assessment, in group C, no statistical significance was achieved. The authors’ physiotherapeutic program had a statistically significant effect on changes in the balance and selected indicators of the motor functions of the examined people. Comparing the results before and after the therapy more improvement changes were noted in women training on an unstable ground compared to women training on a stable ground.

Abstract Background The role of surgery for the primary tumor in breast cancer patients with bone metastases (BM) remains unclear. The purpose of this study was to determine the impact of surgery for the primary tumor in breast cancer patients with BM and to develop prognostic nomograms to predict the overall survival (OS) of breast cancer patients with BM. Methods A total of 3956 breast cancer patients with BM from the Surveillance, Epidemiology, and End Results database between 2010 and 2016 were included. Propensity score matching (PSM) was used to eliminate the bias between the surgery and non-surgery groups. The Kaplan-Meier analysis and the log-rank test were performed to compare the OS between two groups. Cox proportional risk regression models were used to identify independent prognostic factors. Two nomograms were constructed for predicting the OS of patients in the surgery and non-surgery groups, respectively. In addition, calibration curve, receiver operating characteristic (ROC) curve, and decision curve analysis (DCA) were used to evaluate the performance of nomograms. Result The survival analysis showed that the surgery of the primary tumor significantly improved the OS for breast cancer patients with BM. Based on independent prognostic factors, separate nomograms were constructed for the surgery and non-surgery groups. The calibration and ROC curves of these nomograms indicated that both two models have high predictive accuracy, with the area under the curve values ≥0.700 on both the training and validation cohorts. Moreover, DCA showed that nomograms have strong clinical utility. Based on the results of the X-tile analysis, all patients were classified in the low-risk-of-death subgroup had a better prognosis. Conclusion The surgery of the primary tumor may provide survival benefits for breast cancer patients with BM. Furthermore, these prognostic nomograms we constructed may be used as a tool to accurately assess the long-term prognosis of patients and help clinicians to develop individualized treatment strategies.

To examine the impact of a pharmacist’s physical presence on (1) the achievement of individual and combined targets for hemoglobin A1c (A1C), blood pressure (BP), and low-density lipoprotein cholesterol (LDL-C) (composite target), and (2) physician practices in relation to the American Diabetes Association (ADA) standards of medical care.   Methods A retrospective, comparative study of randomly selected diabetic patients seen within an underserved primary care setting at least twice annually between June 1, 2018- December 31, 2019. Patients were allocated by whether they had received care in one of the physician-pharmacist clinics (Group A) or the physician-only clinic (Group B). Study outcomes included the proportion of patients achieving the composite and individual treatment targets for A1C, BP, and LDL-C.   Results A total of 394 patients were included; Majority were underserved African Americans. The composite target was attained by 20% of participants in Group A and 13% in Group B (p=0.09). There were no statistically significant differences in achievement of individual targets between groups. A significantly higher proportion of participants in Group A achieved better control of diastolic blood pressure control (85% vs. 74%), had microalbuminuria tested (50% vs. 12%), were prescribed aspirin (43% vs. 32%), and had lower utilization of non-insulin glucose-lowering agents relative to those in Group B.   Conclusion The impact of a pharmacist’s physical presence on physician practice demonstrated a general trend towards improvement in clinical outcomes related to diabetes management. Future studies are needed to further characterize the impact provided by the physician-pharmacist relationship.

Abstract Background and Aims The impact of hepatitis C virus (HCV) infection on patient survival after renal transplantation was worse. Previously, we found that continuous HCV infection was a significant independent risk factor for actuarial survival (especially at ≥20 years after the transplant procedure) among Japanese renal allograft recipients. This study evaluates the impact of HCV and of the new direct acting antivirals (DAAs) on patient outcomes in renal allograft recipients. Method We studied 46 cases (28 males, 18 females; 37 living-donor cases, 9 deceased-donor cases; mean follow-up period 305 months ranging from 2 to 420 months) out of the 315 renal transplanted patients who underwent the first renal transplantation in Kanazawa Medical University since 1974. They had antibodies against HCV: 11 were positive for HCV RNA and received DAAs (Group A, all of them genotype 1b); 27 were HCV RNA positive and did not receive any treatment (Group B); 8 were negative for HCV RNA (Group C) (Fig.1). Results All Group A patients had HCV RNA negativity after 2-12 weeks of treatment started, and 11 (100%) achieved a sustained virological response (SVR) at 24 weeks. All of them had no adverse effects by the use of DAAs. In this cohort, no patients in Group A died. On the other hand, 15 (55.5%) of 27 in Group B and 3 (37.5%) of 8 in Group C died. Causes of death among Group B were liver cirrhosis (5 cases), hepatocellular carcinoma (2 case), infections complicated with chronic hepatitis (6 cases) in chronic phase, fibrosing cholestatic hepatitis due to HCV (1 case) after surgery, and cardiovascular disease (1 case). The patient survival rate was significantly higher in Group A patients who received DAAs by Kaplan- Meier life table method (Log Rank test, Kay-square 11.7, p=0.004) (Fig.2). Conclusion Our results support the notion that continuous HCV infection was a harmful and that new DAAs were efficient and safe to treat HCV infection after renal transplantation.
