RESUMO
BACKGROUND: In China, fragmented and inefficient health care systems are common while quality resources are limited. To promote an organized, efficient system, the government launched a medical consortium policy to vertically integrate health care through the collaboration of different levels of medical care. Logically, medical staff's knowledge, attitudes and practices (KAP) regarding the consortium are critical for its development. The objective of this study was to explore the KAP regarding the medical consortium among medical staff in a medical consortium in Sichuan Province, China. METHODS: A cross-sectional survey was conducted. In total, 690 medical staff members in 3 cities of Sichuan Province, China, were interviewed from November 2018 to December 2018. The questionnaire consisted of 18 items, including 4 items related to perceived knowledge, 4 items related to attitudes and 2 items related to practices, and was rated on a 5-point Likert scale (one = strongly disagree/do not know, five = strongly agree/know). RESULTS: The effective response sample was 640 copies of the questionnaire, and most medical staff members (92.50%) knew about the cooperation with other hospitals in the medical consortium. Medical staff scored differently on each item in the questionnaire, with the highest score being the item 'agreeing with the ward rounds and clinical teaching and training organized by the leading hospital' (4.54 ± 0.76), and the lowest score being the item 'frequency in participating in ward rounds and clinical teaching organized by the leading hospital' (2.83 ± 1.36). In addition, the effect of demographic characteristics on KAP was evaluated by stepwise multiple regression analysis, and a significant positive correlation was found between all the studied variables by Spearman's correlation (p < 0.05). CONCLUSIONS: This study showed that the attitudes toward and knowledge of the medical consortium significantly contribute to practices, satisfaction with the support work performed by the leading hospital and agreement of improvement after joining the medical consortium. Thus, to improve medical staff's KAP and satisfaction, publicity and educational programs in medical consortia are necessary, and the leading hospital should attach importance to the informatization construction and demand of different medical staff members. CLINICAL TRIAL REGISTRATION: There are no clinical trials in this study.

BACKGROUND: Acknowledging the role of inflammation in colorectal carcinogenesis, this study aimed to evaluate the associations between diet-associated inflammation, as measured by the energy-adjusted dietary inflammatory index (E-DIITM), and distinct stages of colorectal carcinogenesis. METHODS: The Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial enrolled participants without a colorectal cancer history, who were asked to complete baseline questionnaires and food frequency questionnaires. To estimate the associations between the E-DII and risks of newly incident colorectal adenoma, recurrent adenoma, and colorectal cancer, multivariable-adjusted Cox proportional hazards regression models were employed. RESULTS: Among 101,680 participants, with an average age of 65 years, a total of 1177 incident colorectal adenoma cases, 895 recurrent adenoma cases and 1100 colorectal cancer cases were identified. Higher E-DII scores from food and supplement (HRQ5 vs Q1: 0.86 [0.69-1.06], Ptrend: 0.27) or from food only (HRQ5 vs Q1: 0.82 [0.64-1.05], Ptrend: 0.06) were not associated with higher risks of incident adenoma. However, the elevated risk of recurrent adenoma was found in the highest category of E-DII from food plus supplement (HRQ5 vs Q1: 1.63 [1.28-2.03], Ptrend: < 0.001) when compared with the lowest category. A significant association between colorectal cancer risk and E-DII from food plus supplement (HRQ5 vs Q1: 1.34 [1.09-1.65], Ptrend: 0.009) was found, where this association was only pronounced in distal colorectal cancer. CONCLUSION: Higher E-DII scores from diet plus supplement but not from diet only were associated with a higher risk of recurrent adenoma and distal colorectal cancer. The role of nutrient supplements on cancer risk, especially when combined with diet, needs to be elucidated in future studies.

BACKGROUND: Post-traumatic growth induced from cancer diagnosis and treatment could benefit the prognosis of cancer survivors, but intervention based on self-disclosure in group is limited. OBJECTIVE: Aimed to examine the effectiveness of a supportive-expressive group intervention on post-traumatic growth. The impact of the intervention on anxiety and depression were also explored. DESIGN: This randomized clinical trial enrolled patients from June 2017 to September 2018 with a one-month follow-up. Data collectors were blinded to patient grouping. SETTING: A single center study in Chengdu, China. PARTICIPANTS: One hundred sixty-eight participants who met the eligibility criteria were randomly assigned to the intervention group (n = 84) or control group (n = 84); 46 were excluded and 122 patients finished the one-month follow-up. METHODS: Participants in the intervention group received nurse-led support intervention focusing on topics such as "Being a Patient", "Interpersonal Relationships", "Journey for Recovery", and "Planning the Future" while participants in the control group received health education, rehabilitation training etc. according to the nursing routine of breast cancer patients. The intervention was designed in accordance with the diagnosis and treatment process as well as patient needs. Participants in both groups were evaluated three times (T1-baseline before the intervention, T2-end of the intervention, and T3-1 month follow up). Post-traumatic growth, anxiety and depression were evaluated. RESULTS: Participants in the intervention group reported higher level of post-traumatic growth (p < 0.01 or 0.05) and reduced anxiety and depression (p < 0.01 or 0.05 and p < 0.01 or 0.05). The multilevel model indicated that the intervention significantly promoted post-traumatic growth (ßT3 = 7.87, p < 0.05) and dimensions of relating to others (ßT3 = 4.26, p < 0.001), personal strength (ßT3 = 4.27, p < 0.01), appreciation of life (ßT3 = 8.69, p < 0.001), and new possibilities (ßT3 = 1.91, p < 0.05), anxiety (ßT3 = -3.63, p < 0.001), and depression (ßT3 = -2.27, p < 0.001), but had no effect on the dimension of spiritual change. In addition, the multi-level model showed that patients with younger ages (ß = -0.05~-0.52, p < 0.05-0.001), with high school and above education levels (ß = 1.53~9.29, p < 0.01) and accompanied by husbands(ß = -1.48~-8.51, p < 0.05) had more effective intervention and patients with religious belief had a better spiritual change level (ß = 1.86, p < 0.001). CONCLUSIONS: These findings provide evidence for the potential effectiveness of the nurse-led intervention on positive benefits of post-traumatic growth and relieved anxiety and depression for Chinese breast cancer survivors and will inform the design and development of a large randomized controlled trial. CLINICAL RELEVANCE: The supportive-expression group intervention can be applied independently by nurses. The four themes of self-disclosure can help patients grow after trauma, and this method can be used as a psychological support technique for breast cancer patients during hospitalization.

AIMS: To explore the status quo and the influencing factors of residents' knowledge, attitude and practice (KAP) in the prevention and control of coronavirus disease 2019 (COVID-19), and the difficulties or challenges perceived by residents in their preventive practice. DESIGN: An online questionnaire survey. METHODS: The self-designed questionnaire was distributed among residents online in February 2020. Descriptive statistics, two independent samples t-tests, one-way analysis of variance, Pearson's correlation analysis, multivariate linear regression and content analysis were performed. RESULTS: A total of 919 valid questionnaires were collected. The scoring rates of residents' KAP were 85.2%, 92.9% and 84.4% respectively. Main factors influencing residents' knowledge included gender and occupation; while those influencing attitude were occupation, family economic level and knowledge; and those influencing practice included place of residence, occupation, with or without chronic disease, knowledge and attitude. Mass media was the primary approach for people to learn the knowledge and information of COVID-19. Difficulties or challenges faced were mainly lack of protective equipments, concerns about the risk of prevention and control, impact on daily life, work and study, lack of knowledge and consensus, psychological problems and information problems. CONCLUSION: The attitude of residents towards COVID-19 prevention and control is generally positive. The knowledge and practice have been popularized to a certain extent, but there are still deviations or deficiencies in residents' understanding of certain important knowledge and the adoption of relevant preventive measures. Evidence-based tailored public education initiatives are indicated. IMPACT: Findings of this study add important knowledge about residents' understanding, attitude, practice and the influencing factors on COVID-19 prevention and control, which serves as a scientific foundation for optimizing the pandemic public education and decision-making.

BACKGROUND: Under the COVID-19 pandemic, nurses are the mainstay in the fight against the pandemic. PURPOSE: To evaluate potential impact of the pandemic on nurses' professional identity. METHOD: Self-report questionnaires were distributed online. Data collected were compared with available norms. Multivariate logistic regression analyses were employed to calculate the OR of frontline vs. nonfrontline nurses. FINDINGS: The mean of the total score of the scale was 121.12 out of 150. Both the total score and scores on the five dimensions were significantly higher than norms. Frontline nurses had a significantly higher professional identity than non-frontline nurses (total score: odds ratio [OR], 1.19; professional identity evaluation: OR, 1.27; professional social support: OR, 1.18; professional social proficiency: OR, 1.33; and dealing with professional frustration: OR, 1.19). The most frequently mentioned tags were Hope, Frontline, Protection, Outbreak, Work, Situation. DISCUSSION: COVID-19 outbreak was associated with an enhancement in the professional identity of nurses.

Risk of second primary malignancy (SPM) is increasing. We aimed to assess the incidence and related risk factors of SPM among breast cancer (BC) patients from this nested case-control study using the SEER database. BC patients with SPM were identified as the case group and SPM-free patients were defined as the control group. Propensity score matching of cases with controls by the year of the first primary BC diagnosis was conducted at the ratio of 1:5, and 97,242 BC patients were enrolled from 1998 to 2013 after the matching. The incidence of SPM in BC patients stratified by age groups and cancer sites was compared to the general population using the adjusted standardized incidence ratio (SIR) and the risk factors for SPM were examined using Cox proportional hazard regressions. Our study showed BC patients had excess risk for SPM than the general population (adjusted SIR for all cancer sites = 12.94, p < 0.001) and the incidence of SPM among them decreased with age. The risk of SPM was significantly related to the following demographical and clinical variables: age (40-59 vs. 18-39, HR = 1.33; 60-79 vs. 18-39, HR = 2.39; ≥80 vs. 18-39, HR = 2.84), race (black vs. white, HR = 1.12), histological type (lobular BC vs. ductal BC, HR = 1.15), radiotherapy (HR = 1.33), marital status (married vs. single, HR = 0.88) and estrogen receptor status (positive vs. negative, HR = 0.85). Consistent results were found in subgroup analysis stratified by contralateral-breast SPMs and nonbreast SPMs.

BACKGROUND: Early mobilization is inconsistently associated with the recovery of stroke. We aim to examine the effect of early mobilization on patients with acute stroke. METHODS: PubMed, EMBASE, and the Cochrane library were searched up to April 2017. Randomized controlled trials that reported risk estimates or mean with standard deviation were included. Primary outcomes were defined as modified Rankin scale score 0-2 and mortality, and secondary outcomes were Barthel Index, length of stay, and incidence of complications. Summary relative risk, standardized mean difference (SMD), and weighted mean difference (WMD) were calculated as needed. Sensitivity analyses were also conducted to test stability of results. RESULTS: Six studies (8 publications) were included to analyze the effects of early mobilization after stroke. No differences between groups were observed for modified Rankin scale 0-2 (relative risk [RR]: .80; 95% confidence interval [CI]: .58-1.02; I2=45%) and the risk of death (RR: 1.21, 95% CI: .76-1.65; I2=0%). Compared with conventional practice, early mobilization was superior in Barthel Index (SMD: .66; 95% CI: .00-1.31; I2=85.9%), and shorter hospital stay for stroke patients (WMD: -1.97; 95% CI: -2.63 to -1.32; I2=15.3%). We found no significant difference between groups on the incidence of complications. CONCLUSIONS: Current evidence revealed that no statistical significant difference between early mobilization and non-early mobilization was observed on modified Rankin scale score 0-2 and mortality. Interestingly, early mobilization is associated with an increased Barthel Index and shorter hospital stay for patients. Further research is necessary to verify the effect of early mobilization on patients with acute stroke.

PURPOSE: Previous epidemiological studies reported inconsistent results regarding the association between pioglitazone use and the risk of bladder cancer (BC). We conducted a dose-response meta-analysis to assess this association. METHODS: PUBMED and EMBASE databases were searched through August 2015. Pooled results derived from a random-effects model, and the dose-response analyses were conducted for the association between cumulative dose or duration of pioglitazone use and BC risk. RESULTS: 14 studies were included. After comparing "ever use" with "never use" of pioglitazone, an increased risk of BC (HR = 1.16, 95% CI = 1.06 to 1.25) was present, and there was no significant heterogeneity between studies (P for heterogeneity = 0.54, I2 = 0.0%). Every 12 months increase (HR = 1.16, 95% CI = 1.03 - 1.30) or 10 g increase (HR = 1.05, 95% CI = 1.02 - 1.09) in pioglitazone use was marginally associated with elevated BC risk. The evidence of linear relationships was found for the cumulative dose of pioglitazone and BC risk, and a nonlinear curve for association between the duration of pioglitazone use and the risk of BC was revealed. Subgroup analyses revealed that an increased risk of BC for pioglitazone use was observed in European male subjects with more than 12 months of pioglitazone use and in the "multivariate adjusted" group. CONCLUSIONS: Pioglitazone use among subjects with diabetes mellitus increases BC risk mildly. More studies are needed to investigate the association between the cumulative dose of pioglitazone use and BC risk.â©.

BACKGROUND: This study aimed to explore and evaluate the development trends and differential changes in the prevalence of mental and behavioral disorders among the earthquake survivors in exposure groups (highly hard-hit areas) and control groups (general disaster areas) from 2015 to 2019, as well as to investigate the potential influencing factors. METHODS: Data was obtained from the Sichuan Health Information System and the Sichuan Health Yearbook, the prevalence of the exposure group and the control group were calculated, the difference between the two groups was evaluated using the prevalence rate ratio, and a fixed effect model was developed to investigate the potential influencing factors of the prevalence. RESULTS: The prevalence by gender and age in the exposure group was always greater than those in the control group (RR>1), although the disparity between the two proceeded to diminish with time. The urbanization rate (ß = 0.0448, P < 0.05) and disaster area levels (ß = 0.0104, P < 0.05) were risk factors for the prevalence of mental and behavioral disorders. LIMITATIONS: The study only collected data at the group level following the Wenchuan earthquake. Consequently, the findings are only applicable at the group level. Furthermore, diagnostic criteria for various types of mental and behavioral disorders diseases were not provided. CONCLUSIONS: The earthquake has a significant long-term impact on mental health. It is necessary to continuously monitor the mental health of Wenchuan earthquake survivors and take appropriate post-disaster intervention measures.

The retail sector supplies the daily fresh products and increasingly plays a key role in the stability and livability of cities. However, public health events such as COVID-19 have caused frequent product shortages in recent years. The risk of fresh product shortages not only causes retailers to lose profits, but also affects the normal life of residents. In this paper, we address the problem of designing a resilient retail supply network for fresh products under the supply disruption risks and propose a bi-objective mixed-integer programming model. This model can help retailers to select suppliers, distribution centers and transportation routes under different scenarios and implement three resilience strategies, namely, priority supply, multiple sourcing and lateral transshipment. We use the ε -constraint method to transform the multi-objective problem into a single objective model and develop a Lagrangian relaxation algorithm to solve the different scale instances. This model is solved for a real-life case of a supermarket to obtain managerial insights. In the case study, this paper shows the set of Pareto fronts with different inventory periods, maximum allowed decay and decay rate. We calculate the expected total cost under targeted disruption scenarios and evaluate the effectiveness of these resilience strategies when implemented concurrently or separately. Our results identify the most critical suppliers and distribution centers that should be fortified. We elaborate that more resilience strategies are not always better and managers need to take appropriate resilience strategies according to their own problems.

AIMS: To investigate the prevalence of post-traumatic stress disorder (PTSD) symptoms in the hard-hit areas 10 years after the Wenchuan earthquake, and explore the risk factors of long-term PTSD among Wenchuan earthquake survivors. METHODS: A matched case-control study was conducted. The involving participants were from the hard-hit areas 10 years after the Wenchuan earthquake. The collected information includes demographic characteristics, socioeconomic status, behaviour habits, earthquake exposure, perceived social support, physical health and mental health. Mental health status was measured using the PTSD Checklist-Civilian Version (PCL-C). Respondents with PCL-C score ⩾38 were classified as cases, and then the cases and controls were matched based on age (±3 years) and community location according to a ratio of 1:3. RESULTS: We obtained 86 cases and 258 controls. After controlling for confounding factors, it was found that lower income (OR 2.42; 95% CI 1.16-5.03), chronic diseases (OR 3.00; 95% CI 1.31-6.88) and death of immediate families in the earthquake (OR 7.30; 95% CI 2.36-22.57) were significantly associated with long-term PTSD symptoms. CONCLUSION: Even 10 years after the Wenchuan earthquake, the survivors in the hard-hit areas still suffered from severe mental trauma. Low income, chronic diseases and death of immediate families in the earthquakes are significantly associated with long-term PTSD symptoms. Interventions by local governments and health institutions to address these risk factors should be undertaken to promote the health of survivors.

BACKGROUND: Although patients diagnosed with ductal carcinoma in situ (DCIS) harbor excellent overall survival (OS) after breast-conserving therapy, the evidence regarding to surgical management for ipsilateral breast tumor recurrence (IBTR) is scarce. This study aimed to assess the prognosis of repeated breast-conserving surgery (BCS) versus mastectomy for IBTR in DCIS survivors. MATERIALS AND METHODS: Herein, 5344 DCIS cases with IBTR were identified during 702,748 person-years of follow-up, 3532 (66.09%) received mastectomy, and 1812 (33.91%) received repeated BCS. Cox regression and competing risk regression were employed to estimate multivariable-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for OS and breast cancer-specific survival (BCSS), which was respectively calculated within spontaneous and matched cohorts. RESULTS: After adjustment for confounders, no statistically significant survival difference was observed between the repeated BCS and mastectomy for patients with DCIS with IBTR. The stratified analyses further revealed that patients with DCIS with IBTR receiving repeated BCS combined with radiation therapy were associated with both superior OS (HR, 0.79; CI, 0.64-0.98; P = .04) and BCSS (HR, 0.54; CI, 0.33-0.90; P = .02) compared with counterparts undergoing mastectomy. Furthermore, patients with DCIS who were age older than 60 years at IBTR diagnosis benefit from repeated BCS with radiotherapy (HR, 0.44; CI, 0.24-0.84; P = .01) than mastectomy. CONCLUSION: We suggest that repeated BCS with radiation therapy deserves consideration when DCIS survivors suffered IBTR. The choice of surgical management should be tailored based on patients' age at IBTR diagnosis and size of recurrent disease.

BACKGROUND: Emergency and intensive care unit nurses are the main workforce fighting against COVID-19. Their professional identity may affect whether they can actively participate and be competent in care tasks during the pandemic. OBJECTIVE: To examine the level of and changes in professional identity of Chinese emergency and intensive care unit nurses as the COVID-19 pandemic builds. METHODS: A cross-sectional survey composed of the Professional Identity Scale for Nurses plus 2 open-ended questions was administered to Chinese emergency and intensive care unit nurses through an online questionnaire. RESULTS: Emergency and intensive care unit nurses had a medium level of professional identity. Participants' total and item mean scores in 5 professional identity dimensions were higher than the professional identity norm established by Liu (P < .001). The greatest mean item score difference was in the dimension of professional identity evaluation (3.57 vs 2.88, P < .001). When asked about their feelings witnessing the COVID-19 situation and their feelings about participating in frontline work, 68.9% and 83.9%, respectively, reported positive changes in their professional identity. CONCLUSIONS: The professional identity of emergency and intensive care unit nurses greatly improved during the early stages of the COVID-19 pandemic. This finding may be attributed to more public attention and recognition of nurses' value, nurses' professional fulfillment, and nurses' feelings of being supported, motivated, respected, and valued.

The increased incidence of secondary hematologic malignancies (SHM) is a well-known, potentially fatal, complication after cancer treatment. It is unknown if patients with ductal carcinoma in situ (DCIS) of the breast treated with external beam radiotherapy (RT) and who survive long-term have increased risks of secondary hematologic malignancies (SHM), especially for low/intermediate-risk subsets with limited benefits from RT. DCIS patients in Surveillance, Epidemiology, and End Results (SEER) registries (1975-2016) were identified. Relative risks (RR), hazard ratio (HR), and standardized incidence ratios (SIR) were calculated to assess the SHM risk and subsequent survival times. SHM development, defined as a nonsynchronous SHM occurring ≥1 year after DCIS diagnosis, was our primary endpoint. Of 184,363 eligible patients with DCIS, 77,927 (42.3%) in the RT group, and 106,436 (57.7%) in the non-RT group, 1289 developed SHMs a median of 6.4 years (interquartile range, 3.5 to 10.3 years) after their DCIS diagnosis. Compared with DCIS patients in the non-RT group, RT was associated with increased early risk of developing acute lymphoblastic leukemia (ALL; hazard ratio, 3.15; 95% CI, 1.21 to 8.17; P = 0.02), and a delayed risk of non-Hodgkin lymphoma (NHL; hazard ratio, 1.33; 95% CI, 1.09 to 1.62; P < 0.001). This increased risk of ALL and NHL after RT was also observed in subgroup analyses restricted to low/intermediate-risk DCIS. In summary, our data suggest that RT after breast conserving surgery for DCIS patients should be cautiously tailored, especially for low and intermediate-risk patients. Long-term SHM surveillance after DCIS diagnosis is warranted.
RESUMO
BACKGROUND & AIMS: Vitamin K prevents growth and metastasis of certain cancers, but there is little evidence regarding the association between dietary vitamin K and breast cancer incidence and death. We sought to examine whether intakes of total vitamin K, phylloquinone (vitamin K1) and menaquinones (MKs) (vitamin K2) may influence risks of breast cancer incidence and death in the US population. METHODS: Herein, 2286 breast cancer cases and 207 breast cancer deaths were identified during 702,748 person-years of follow-up. Cox regression and competing risk regression were used to estimate multivariable-adjusted hazards ratios (HRs) and 95% confidence intervals (95% CIs) by dietary vitamin K intake quintile (Q) for risk of breast cancer incidence and mortality. RESULTS: After adjustment for confounders, the total MK intake was associated with an increased risk of breast cancer (HR Q5 vs Q1, 1.26; 95% CI, 1.05 to 1.52; Ptrend, 0.01) and death from breast cancer (HR Q5 vs Q1, 1.71; 95% CI, 0.97 to 3.01; Ptrend, 0.04). Non-linear positive dose-response associations with risks of breast cancer incidence and death were found for total MKs intake (Pnon-linearity<0.05). No statistically significant associations were observed between the intake of total vitamin K and phylloquinone and breast cancer. CONCLUSIONS: The present study suggests that total MK intake was associated with an altered risk of the occurrence and death of breast cancer in the general US population. If our findings are replicated in other epidemiological studies, reducing dietary intake of menaquinones may offer a novel strategy for breast cancer prevention.

BACKGROUND: Post-traumatic stress disorder (PTSD) is common psychological distress after natural disasters, which is persistent. Chronic PTSD leads to a heavy disease burden. The purpose of this study is to explore the prevalence and influencing factors of chronic PTSD among survivors in the hard-hit areas ten years after the Wenchuan earthquake. MATERIALS AND METHODS: A cross-sectional survey was conducted on residents aged 16 or above in hard-hit areas through a multi-stage sampling approach ten years after the Wenchuan earthquake. The items of the questionnaire included demographic characteristics and earthquake exposure factors, and the PTSD Checklist-Civilian Version (PCL-C) was used to evaluate the PTSD of the respondents. RESULTS: A total of 1039 complete questionnaires were obtained. The median age of 1039 respondents was 60 years, 63.2% of whom were female, 70.2% were illiterate or had received primary education, and 58% had an annual household income of less than 20,000 yuan (US$ 2871.3). The rate of PTSD was 9.1% (95/1039). After controlling for confounding factors, it was found that higher income level and education level, and moving to concentrated rural settlement (CRS) after the earthquake might be protective factors for the long-term mental health of survivors in the hard-hit areas, and the loss of immediate families in the earthquake was an important risk factor. CONCLUSION: Even though ten years have passed since the Wenchuan earthquake, the survivors in the hard-hit areas still have a serious mental disorder.

Inflammation-modulating nutrients and inflammatory markers are established cancer risk factors, however, evidence regarding the association between post-diagnosis diet-associated inflammation and breast cancer survival is relatively sparse. We aimed to examine the association between post-diagnosis dietary inflammatory index (DII®) and risks of all-cause and breast cancer-specific mortality. A total of 1064 female breast cancer survivors in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening (PLCO) Trial prospective cohort, were included in this analysis if they had completed the diet history questionnaire (DHQ). Energy-adjusted DII (E-DIITM) scores were calculated based on food and supplement intake. Cox regression and competing risk models were used to estimate multivariable-adjusted hazards ratios (HRs) and 95% confidence intervals (95% CIs) by E-DII tertile (T) for all-cause and breast cancer-specific mortality. With median follow-up of 14.6 years, there were 296 (27.8%) deaths from all causes and 100 (9.4%) breast cancer-specific death. The E-DII was associated with all-cause mortality (HR T3 vs T1, 1.34; 95% CI, 1.01-1.81; P trend, 0.049, Table 2) and breast cancer mortality (HR T3 vs T1, 1.47; 95% CI, 0.89-2.43; P trend, 0.13; multivariable-adjusted HR for 1-unit increment: 1.10; 95% CI: 1.00-1.22). Non-linear positive dose-response associations with mortality from all causes were identified for E-DII scores (P non-linearity < 0.05). The post-diagnosis E-DII was statistically significantly associated with mortality risk among breast cancer survivors. Long-term anti-inflammatory diet might be a means of improving survival of breast cancer survivors.
RESUMO
INTRODUCTION: Role of surgery in the management of de novo stage IV breast cancer (BC) remains controversial. We aimed to determine the survival benefit of primary surgery on the basis of metastatic pattern. MATERIALS AND METHODS: A retrospective cohort study based on the SEER database was conducted to identify patients with de novo stage IV BC diagnosed between 2010 and 2015. Patients were divided into surgery and non-surgery group, and propensity score weighting was used to balance clinicopathologic factors between groups. RESULTS: Of 8142 de novo stage IV BC patients, 1891 (23%) cases were managed with surgery and 6251 (77%) cases were managed without surgery. There were 3821 all-cause deaths and 3291 BC specific deaths over a median follow-up of 22 months. The weighted 3-year overall survival (OS) for the surgery group was 54.5%, compared to 47.7% (Pâ¯<â¯0.001) for the non-surgery group. The magnitude of the survival difference with surgery was significantly correlated with metastatic patterns (Pinteraction<0.05). Significant survival improvements in surgery group compared with non-surgery group were observed in patients with bone-only metastasis (adjusted HRâ¯=â¯0.83, Pâ¯<â¯0.05) or multiple metastases with bone involved (adjusted HRâ¯=â¯0.76, Pâ¯<â¯0.05), whereas survival inferiority of surgery was found for patients with multiple visceral organs-only metastases (adjusted HRâ¯=â¯2.08, Pâ¯<â¯0.05). CONCLUSION: The survival benefit offered by surgery for de novo stage IV BC varies by metastatic patterns. Decisions for primary surgery of de novo stage IV BC patients should be tailored according to metastatic pattern.

BACKGROUND: The role of histology subtype on the prognosis of T1-2 breast cancer patients receiving breast-conserving surgery (BCS) is not clear. METHODS: The Surveillance, Epidemiology, and End Results (SEER) Program was used to compare overall survival, second primary cancer-free survival (CFS), and local recurrence risk (LR) for patients with invasive lobular carcinoma (ILC) and invasive ductal carcinoma (IDC), both receiving BCS. RESULTS: The study enrolled 196,688 patients with T1-2 disease receiving BCS, including 12,906 with ILC and 183,782 with IDC. Patients with IDC showed higher unadjusted annual rates of BCS than ILC. Five- and 10-year estimated survival rates were, respectively, 92.06% and 86.14% in ILC, compared to 90.50% and 85.26% in IDC (P = .12). In multivariable Cox regression, ILC patients showed advantage over IDC in overall survival (hazard ratio [HR] = 0.93, P = .001), whereas no significant differences in CFS (HR = 1.03, P = .33) and LR (HR = 1.17, P = .06) were found, which were consistent with results from matched cohort. In subgroup analyses, patients with grade III ILC had poorer CFS (HR = 1.23, P = .009) and higher LR (HR = 1.59, P = .01) than IDC. CONCLUSION: Histologic type is of prognostic importance in T1-2 patients receiving BCS, and surgeons should be cautious in performing BCS for individuals with grade III ILC.

PURPOSE: Accumulating evidence indicated that triple-negative breast cancer (TNBC) can stimulate stronger immune responses than other subtypes of breast cancer. We hypothesized that integrating immune-related genomic signatures with clinicopathologic factors may yield a predictive accuracy exceeding that of the currently available system. METHODS: Ten signatures that reflect specific immunogenic or immune microenvironmental features of TNBC were identified and re-analyzed using bioinformatic methods. Then, clinically annotated TNBC (n = 711) with the corresponding expression profiles, which predicted a patient's probability of disease-free survival (DFS) and overall survival (OS), was pooled to evaluate their prognostic values and establish a clinicopathologic-genomic nomogram. Three and two immune features were, respectively, selected out of 10 immune features to construct nomogram for DFS and OS prediction based on multivariate backward stepwise Cox regression analyses. RESULTS: By integrating the above immune expression signatures with prognostic clinicopathologic features, clinicopathologic-genomic nomograms were cautiously constructed, which showed reasonable prediction accuracies (DFS: HR, 1.79; 95% CI, 1.46-2.18, P < 0.001; AUC, 0.71; OS: HR, 1.96; 95% CI, 1.54-2.49; P < 0.001; AUC, 0.73). The nomogram showed low-risk subgroup had higher immune checkpoint molecules (PD-L1, PD-1, CTLA-4, LAG-3) expression and benefited from radiotherapy (HR, 0.2, 95% CI, 0.05-0.89; P = 0.034) rather than chemotherapy (HR, 1.26, 95% CI, 0.66-2.43; P = 0.485). CONCLUSIONS: These findings offer evidence that immune-related genomic data provide independent and complementary prognostic information for TNBC, and the nomogram might be a practical predictive tool to identify TNBC patients who would benefit from chemotherapy, radiotherapy, and upcoming popularity of immunotherapy.
