GATIS score for predicting the prognosis of rectal neuroendocrine neoplasms:A Chinese multicenter study of 12-year experience

BACKGROUND There is currently a shortage of accurate,efficient,and precise predictive instruments for rectal neuroendocrine neoplasms(NENs).AIM To develop a predictive model for individuals with rectal NENs(R-NENs)using data from a large cohort.METHODS Data from patients with primary R-NENs were retrospectively collected from 17 large-scale referral medical centers in China.Random forest and Cox proportional hazard models were used to identify the risk factors for overall survival and progression-free survival,and two nomograms were constructed.RESULTS A total of 1408 patients with R-NENs were included.Tumor grade,T stage,tumor size,age,and a prognostic nutritional index were important risk factors for prognosis.The GATIS score was calculated based on these five indicators.For overall survival prediction,the respective C-indexes in the training set were 0.915(95%confidence interval:0.866-0.964)for overall survival prediction and 0.908(95%confidence interval:0.872-0.944)for progression-free survival prediction.According to decision curve analysis,net benefit of the GATIS score was higher than that of a single factor.The time-dependent area under the receiver operating characteristic curve showed that the predictive power of the GATIS score was higher than that of the TNM stage and pathological grade at all time periods.CONCLUSION The GATIS score had a good predictive effect on the prognosis of patients with R-NENs,with efficacy superior to that of the World Health Organization grade and TNM stage.

Endoscopic ultrasonography-related diagnostic accuracy and clinical significance on small rectal neuroendocrine neoplasms

This research aimed to examine the diagnostic accuracy and clinical significance of endoscopic ultrasonography(EUS)in the context of small rectal neuroendocrine neoplasms(NENs).A total of 108 patients with rectal subepithelial lesions(SELs)with a diameter of<20 mm were included in the analysis.The diagnosis and depth assessment of EUS was compared to the histology findings.The prevalence of NENs in rectal SELs was 78.7%(85/108).The sensitivity of EUS in detecting rectal NENs was 98.9%(84/85),while the specificity was 52.2%(12/23).Overall,the diagnostic accuracy of EUS in identifying rectal NENs was 88.9%(96/108).The overall accuracy rate for EUS in assessing the depth of invasion in rectal NENs was 92.9%(78/84).Therefore,EUS demonstrates reasonable diagnostic accuracy in detecting small rectal NENs,with good sensitivity but inferior specificity.EUS may also assist physicians in assessing the depth of invasion in small rectal NENs before endoscopic excision.

Influence of humanistic care-based operating room nursing on safety,recovery,and satisfaction after radical surgery for colorectal carcinoma

BACKGROUND Radical surgery is a preferred treatment for colorectal carcinoma,wherein nursing intervention is essential for postoperative recovery and prevention of complications.Recently,the application of humanistic care in medical care has attracted attention.Humanistic care emphasizes comprehensive care,with importance attached to patients’physical needs as well as psychological and emotional support to provide more humane and personalized care services.However,no clinical reports have examined the use of humanistic care in patients undergoing radical surgery for colorectal carcinoma.AIM To investigate the influence of humanistic care-based operating room nursing on the safety,postoperative recovery,and nursing satisfaction of patients who have undergone radical surgery for colorectal carcinoma.METHODS In total,120 patients with rectal cancer who underwent surgery in Zhongnan Hospital of Wuhan University between August 2023 and March 2024 were selected and grouped based on the nursing methods employed.Of these patients,55 were treated with routine nursing intervention(control group)and 65 were provided humanistic care-based operating room nursing(research group).The patients’vital signs were recorded,including systolic/diastolic blood pressure(SBP/DBP)and heart beats per minute(BPM),as well as serum stress indices,including norepinephrine(NE),adrenal hormone(AD),and cortisol(Cor).Postoperative recovery and complications were also recorded.Patients’negative emotions,life hope,and nursing satisfaction were evaluated using the Self-rating Depression/Anxiety Scale(SDS/SAS),Herth Hope Index(HHI),and self-deve-loped nursing satisfaction questionnaire,respectively.RESULTS During emergence from anesthesia,SBP,DBP,and BPM levels were found to be lower in the research group than those in the control group,also serum Cor,AD,and NE levels were lower.In addition,the research group had shorter operative,awakening,anal exhaust,first postoperative ambulation,drainage tube removal,intestinal recovery,and hospital times.The total complication rate and the SDS and SAS scores were lower in the research group than those in the control group.The HHI and nursing satisfaction scores were higher in the research group.CONCLUSION Humanistic care-based operating room nursing can mitigate physiological stress responses,reduce postoperative complications,promote postoperative recovery,relieve adverse psychological emotions,and enhance life hope and nursing satisfaction in patients undergoing radical surgery for colorectal carcinoma,which can be popularized in clinical practice.

Enhancing prognostic accuracy in predicting rectal neuroendocrine neoplasms

The recently published retrospective study introduces the GATIS score,a new predictive model for rectal neuroendocrine neoplasms.By analyzing data from a large Chinese multicenter cohort,the study shows that the GATIS score,incor-porating tumor grade,T stage,tumor size,age,and prognostic nutritional index,demonstrates superior predictive power for overall survival and progression-free survival compared to traditional World Health Organization grade and tumor,nodes and metastases staging systems.This editorial aims to discuss the impor-tance of the GATIS score,its potential impact on clinical practice,and the strengths and limitations of the study.Finally,it explores the significance,methodology,and clinical implications of these findings.

Evaluation of the GATIS score for predicting prognosis in rectal neuroendocrine neoplasms

The GATIS score,developed by Zeng et al,represents a significant advancement in predicting the prognosis of patients with rectal neuroendocrine neoplasms(RNENs).This study,which included 1408 patients from 17 major medical centres in China over 12 years,introduces a novel prognostic model based on the tumour grade,T stage,tumour size,age,and the prognostic nutritional index.Compared with traditional methods such as the World Health Organization classification and TNM staging systems,the GATIS score has superior predictive power for overall survival and progression-free survival.With a C-index of 0.915 in the training set and 0.812 in the external validation set,the GATIS score’s robustness and reliability are evident.The study’s use of a large,multi-centre cohort and rigorous validation processes underscore its significance.The GATIS score offers clinicians a powerful tool to accurately predict patient outcomes,guide treatment decisions,and improve follow-up strategies.This development represents a crucial step forwards in the management of R-NENs,addressing the complexity and variability of these tumours and setting a new benchmark for future research and clinical practice.

Analysis of Humanistic Nursing Care in Regulating the Emotion, Satisfaction, and Sleep Quality of Inpatients with Hematologic Neoplasms

Objective:To explore the clinical application value of humanistic nursing care in the treatment of hematologic neoplasm inpatients.Methods:Fifty-two patients with hematologic neoplasms admitted to a hospital from May 2019 to February 2022 were selected as the research subjects.According to a random number table,they were divided into two groups:the control group(n=25,routine clinical nursing)and the observation group(n=27,humanistic nursing care).The negative emotion score,nursing satisfaction,and sleep quality were compared between the two groups under different nursing modes.Results:The SAS and SDS scores before and after nursing were compared between the two groups.There was no significant difference between the two groups before nursing(p>0.05).However,the SDS and SAS scores in the two groups after nursing were lower than those before nursing,in which the observation group was slightly lower than the control group,and the difference was statistically significant(p<0.001).In terms of nursing satisfaction,it was as high as 96.29%in the observation group,whereas in the control group,the satisfaction rate was only 72.00%;the PSQI scores were compared between the two groups before and after nursing,and there was no significant difference between the two groups before nursing(p>0.05).However,the PSQI scores and total score of the observation group after nursing were lower than those of the control group(p<0.001).Conclusion:In the clinical treatment of patients with hematologic neoplasms,the implementation of humanistic nursing care can significantly improve patients’anxiety,depression,other negative emotions,sleep quality,and nursing satisfaction,all of which have significance in promoting the prognosis of patients and improving their quality of life.

Feasibility and safety of minimally invasive multivisceral resection for T4b rectal cancer:A 9-year review

BACKGROUND Colorectal cancer is the third most common cancer and the second highest cause of cancer-related mortality worldwide.About 5%-10%of patients are diagnosed with locally advanced rectal cancer(LARC)on presentation.For LARC invading into other structures(i.e.T4b),multivisceral resection(MVR)and/or pelvic ex-enteration(PE)remains the only potential curative surgical treatment.MVR and/or PE is a major and complex surgery with high post-operative morbidity.Minimally invasive surgery(MIS)has been shown to improve short-term post-operative outcomes in other gastrointestinal malignancies,but there is little evi-dence on its use in MVR,especially so for robotic MVR.This is a single-center retrospective cohort study from 1st January 2015 to 31st March 2023.Inclusion criteria were patients diagnosed with cT4b rectal cancer and underwent MVR,or stage 4 disease with resectable systemic metastases.Pa-tients who underwent curative MVR for locally recurrent rectal cancer,or me-tachronous rectal cancer were also included.Exclusion criteria were patients with systemic metastases with non-resectable disease.All patients planned for elective surgery were enrolled into the standard enhanced recovery after surgery pathway with standard peri-operative management for colorectal surgery.Complex sur-gery was defined based on technical difficulty of surgery(i.e.total PE,bladder-sparing prostatectomy,pelvic lymph node dissection or need for flap creation).Our primary outcomes were the margin status,and complication rates.Cate-gorical values were described as percentages and analysed by the chi-square test.Continuous variables were expressed as median(range)and analysed by Mann-Whitney U test.Cumulative overall survival(OS)and recurrence-free survival(RFS)were analysed using Kaplan-Meier estimates with life table analysis.Log-rank test was performed to determine statistical significance between cumulative estimates.Statistical significance was defined as P<0.05.Meier estimates with life table analysis.Log-rank test was performed to determine statistical significance between cumulative estimates.Statistical significance was defined as P<0.05.RESULTS A total of 46 patients were included in this study[open MVR(oMVR):12(26.1%),miMVR:36(73.9%)].Patients’American Society of Anesthesiologists score,body mass index and co-morbidities were comparable between oMVR and miMVR.There is an increasing trend towards robotic MVR from 2015 to 2023.MiMVR was associated with lower estimated blood loss(EBL)(median 450 vs 1200 mL,P=0.008),major morbidity(14.7%vs 50.0%,P=0.014),post-operative intra-abdominal collections(11.8%vs 50.0%,P=0.006),post-operative ileus(32.4%vs 66.7%,P=0.04)and surgical site infection(11.8%vs 50.0%,P=0.006)compared with oMVR.Length of stay was also shorter for miMVR compared with oMVR(median 10 vs 30 d,P=0.001).Oncological outcomes-R0 resection,recurrence,OS and RFS were comparable between miMVR and oMVR.There was no 30-d mortality.More patients underwent robotic compared with laparoscopic MVR for complex cases(robotic 57.1%vs laparoscopic 7.7%,P=0.004).The operating time was longer for robotic compared with laparoscopic MVR[robotic:602(400-900)min,laparoscopic:Median 455(275-675)min,P<0.001].Incidence of R0 resection was similar(laparoscopic:84.6%vs robotic:76.2%,P=0.555).Overall complication rates,major morbidity rates and 30-d readmission rates were similar between la-paroscopic and robotic MVR.Interestingly,3-year OS(robotic 83.1%vs 58.6%,P=0.008)and RFS(robotic 72.9%vs 34.3%,P=0.002)was superior for robotic compared with laparoscopic MVR.CONCLUSION MiMVR had lower post-operative complications compared to oMVR.Robotic MVR was also safe,with acceptable post-operative complication rates.Prospective studies should be conducted to compare short-term and long-term outcomes between robotic vs laparoscopic MVR.

Transanal Endoscopic Microsurgery (TEM) for Rectal Neoplasms

Introduction: The abdominal approach for the treatment of rectal tumors is associated with a considerable rate of morbidity. Transanal Endoscopic Microsurgery (TEM) is an alternative technique that is less invasive than radical surgery, and therefore has a lower associated morbidity. Moreover, with proper patient selection, TEM presents oncological outcomes comparable to radical surgery. The aim of this study is to review our results obtained with TEM and discuss its role in the treatment of malignant rectal lesions. Patients and Methods: A prospective descriptive study from June 2008 until February 2011. The indications for TEM were: early rectal neoplastic lesions (T1N0M0) with good prognostic factors;neoplastic lesions in more advanced stages in selected patients (high surgical risk, refusal of radical surgery or stoma, and palliative intention). Results: Resection by TEM was performed on 19 patients. The average hospital stay was 5.7 days with an associated morbidity of 16.7%. R0 resection was 88.8%. During the follow-up of 15 (3 - 31) months, no recurrence has been shown. Conclusions: TEM is a safe and effective procedure for the treatment of selected early malignant rectal lesions and is associated with low morbidity. It is a therapeutic strategy based on a multidisciplinary team, careful patient selection, an audited surgical technique and a strict follow-up protocol.

Knowledge and Attitudes of Oncology Nurses Toward Clinical Trials-A Secondary Publication

Purpose:The purpose of this study was to identify the knowledge and attitudes of oncology nurses toward clinical trials and to provide evidence for the development of clinical trial education programs for oncology nurses.Methods:The study was conducted on 142 nurses who had more than six months of nursing experience working with cancer patients at a tertiary hospital in Seoul,Korea.A structured questionnaire was used to measure the knowledge and attitudes of oncology nurses toward clinical trials.Results:The participants scored an average of 15.03±3.52 out of 19 in terms of knowledge about clinical trials.In terms of attitudes toward clinical trials,the participants scored an average of 5.91±1.37 out of 8.There was a significant positive correlation between the knowledge and attitudes of the participants toward clinical trials(r=0.23,P=0.007).Conclusion:This study found that there was a relationship between the knowledge and attitudes of oncology nurses toward clinical trials.To improve the competency of oncology nurses and provide high-quality care to patients participating in clinical trials,more systematic and sustainable education is required.

Impact of technology on indications and limitations for transanal surgical removal of rectal neoplasms

Transanal surgery has and continues to be well accepted for local excision of benign rectal disease not amenable to endoscopic resection. More recently, there has been increasing interest in applying transanal surgery to local resection of early malignant disease. In addition, some groups have started utilizing a transanal route in order to accomplish total mesorectal excision(TME) for more advanced rectal malignancies. We aim to review the role of various transanal and endoscopic techniquesin the local resection of benign and malignant rectal disease based on published trial data. Preliminary data on the use of transanal platforms to accomplish TME will also be highlighted. For endoscopically unresectable rectal adenomas, transanal surgery remains a widely accepted method with minimal morbidity that avoids the downsides of a major abdomino-pelvic operation. Transanal endoscopic microsurgery and transanal minimally invasive surgery offer improved visualization and magnification, allowing for finer and more precise dissection of more proximal and larger rectal lesions without compromising patient outcome. Some studies have demonstrated efficacy in utilizing transanal platforms in the surgical management of early rectal malignancies in selected patients. There is an overall higher recurrence rate with transanal surgery with the concern that neither chemoradiation nor salvage surgery may compensate for previous approach and correct the inferior outcome. Application of transanal platforms to accomplish transanal TME in a natural orifice fashion are still in their infancy and currently should be considered experimental. The current data demonstrate that transanal surgery remains an excellent option in the surgical management of benign rectal disease. However, care should be used when selecting patients with malignant disease. The application of transanal platforms continues to evolve. While the new uses of transanal platforms in TME for more advanced rectal malignancy are exciting, it is important to remain cognizant and not sacrifice long term survival for short term decrease in morbidity and improved cosmesis.

Meta-analysis of the effect of continuing nursing on the psychological status of rectal cancer patients undergoing stoma

Objective:To systematically evaluate the effect of continuous nursing on the psychological status of rectal cancer patients undergoing stoma.Methods:Five databases including China HowNet,Chongqing Weipu Chinese Science and Technology Database,Wanfang Database,Embase and PubMed were searched.Randomized controlled trials were collected on the effect of continuing nursing on the psychological status of rectal cancer patients undergoing stoma.The searching time was from the establishment of the database to March 30,2019.RevMan 5.3 software was used to analyze the bias risk of the study after two researchers independently screened the researchers,extracted the data and evaluated the bias risk of the study.Results:A total of 15 studies were included.Meta-analysis showed that the continuing nursing group improved anxiety[MD=-10.89,95%CI(-13.52,-8.26),P<0.00001],depression[MD=-4.78,95%CI(-5.77,-3.80,P<0.00001],fear[MD=-6.06,95%CI(-7.70,-4.43),P<0.00001],hostile[MD=-7.00,95%CI(-13.62,-0.38),P=0.04<0.05],somatization[MD=-7.63,95%CI(-13.49,-1.77),P=0.01<0.05].The self-care ability[MD=38.24,95%CI(35.38,41.11),P<0.00001]was superior to the routine nursing group.Conclusion:Continuous nursing has more advantages than routine nursing,and it can improve the negative psychological state of rectal cancer patients undergoing stoma.Due to the limitations of the quantity and quality of the included studies,the above conclusions need to be verified by more high-quality studies.

Effects of cooperative nursing and patient education on postoperative infection and self-efficacy in gastrointestinal tumors

BACKGROUND Gastrointestinal tumors have a high incidence rate.The application value of the cooperative nursing care system of medical care has received widespread attention in recent years.However,there are few studies on the value of the joint application of collaborative nursing care and self-efficacy education.AIM To explore the effect of cooperative nursing care management/self-efficacy education on postoperative infection and self-efficacy in gastrointestinal tumor surgery patients.METHODS A total of 102 patients with gastrointestinal tumors treated in our hospital from October 2018 to February 2020 were selected and divided into a conventional group(n=51)and a combined group(n=51)according to the nursing plan.The routine group adopted routine nursing,and the joint group adopted the medical care cooperative responsibility system nursing management combined with selfefficacy education.The self-efficacy scores,coping style scores,self-experience burden scores,and postoperative complication rates of the two groups before and after intervention were counted.RESULTS After intervention,the daily life behavior management,cognitive symptom management,and disease management scores of the two groups were higher than those before the intervention,and those of the combined group were higher than those of the conventional group(all P=0.000).After the intervention,the positive response scores of the two groups were higher than those before the intervention,the negative response scores were lower than those before the intervention,and the combined group was better than the conventional group(all P=0.000).After the intervention,the two groups’emotional,economic,and physical factor scores were lower than those before the intervention,and the combined group was lower than the conventional group(all P=0.000).The incidence of infection in the combined group(1.96%)was lower than that in the conventional group(15.69%)(P=0.036).CONCLUSION Cooperative nursing care management and self-efficacy education improved the physical and mental states of gastrointestinal cancer surgery patients,change the response to disease,and reduce the risk of postoperative infection.

Effectiveness of integrated nursing interventions for fatigue in patients with advanced cancer:a systematic review of randomized controlled trials

Objective:To evaluate the effectiveness of integrated nursing interventions for fatigue in patients with advanced cancer.Methods:Medline,Pubmed,Embase,CINAHL,Web of Science,and the Cochrane Library were searched systematically till June 2017.A systematic review was conducted to collect randomized controlled trials(RCTs)reporting on the effect of nurse-driven interventions to improve fatigue in patients with advanced cancer.Quality assessment was conducted using the Cochrane Collaboration’s risk of bias tool.Results:Six RCTs involving 736 adult participants were included.The fatigue intensity was improved significantly by nursing interventions.The analyzed results revealed significant improvements in the intervention group:less than 3 months(standard mean difference[SMD]=?0.33,95%confidence interval[CI][?0.48,?0.19],P<0.01)and more than or equal to 3 months(SMD=?0.40,95%CI[?0.57,?0.24],P<0.01).Four studies with a moderate risk of bias were judged,and the remaining studies were at high risk of bias.Conclusions:The results indicate that integrated nursing interventions may relieve fatigue in patients with advanced cancer.However,due to the high risk of bias in most of the included studies and the diversity of interventions,the results and implementation process should be carefully monitored.

Different oncological features of colorectal cancer codon-specific KRAS mutations:Not codon 13 but codon 12 have prognostic value

BACKGROUND Approximately 40%of colorectal cancer(CRC)cases are linked to Kirsten rat sarcoma viral oncogene homolog(KRAS)mutations.KRAS mutations are associated with poor CRC prognosis,especially KRAS codon 12 mutation,which is associated with metastasis and poorer survival.However,the clinicopathological characteristics and prognosis of KRAS codon 13 mutation in CRC remain unclear.AIM To evaluate the clinicopathological characteristics and prognostic value of codonspecific KRAS mutations,especially in codon 13.METHODS This retrospective,single-center,observational cohort study included patients who underwent surgery for stage I-III CRC between January 2009 and December 2019.Patients with KRAS mutation status confirmed by molecular pathology reports were included.The relationships between clinicopathological characteristics and individual codon-specific KRAS mutations were analyzed.Survival data were analyzed to identify codon-specific KRAS mutations as recurrence-related factors using the Cox proportional hazards regression model.RESULTS Among the 2203 patients,the incidence of KRAS codons 12,13,and 61 mutations was 27.7%,9.1%,and 1.3%,respectively.Both KARS codons 12 and 13 mutations showed a tendency to be associated with clinical characteristics,but only codon 12 was associated with pathological features,such as stage of primary tumor(T stage),lymph node involvement(N stage),vascular invasion,perineural invasion,tumor size,and microsatellite instability.KRAS codon 13 mutation showed no associations(77.2%vs 85.3%,P=0.159),whereas codon 12 was associated with a lower 5-year recurrence-free survival rate(78.9%vs 75.5%,P=0.025).In multivariable analysis,along with T and N stages and vascular and perineural invasion,only codon 12(hazard ratio:1.399;95%confidence interval:1.034-1.894;P=0.030)among KRAS mutations was an independent risk factor for recurrence.CONCLUSION This study provides evidence that KRAS codon 13 mutation is less likely to serve as a prognostic biomarker than codon 12 mutation for CRC in a large-scale cohort.

Risk of ileal pouch neoplasms in patients with familial adenomatous polyposis

Restorative proctocolectomy is the most common surgical option for patients with familial adenomatous polyposis(FAP). However,adenomas may develop in the ileal pouch mucosa over time,and even carcinoma in the pouch has been reported. We therefore reviewed the prevalence,nature,and treatment of adenomas and carcinoma that develop after proctocolectomy in the ileal pouch mucosa in patients with FAP. In 25 reports that were reviewed,the incidence of adenomas in the ileal pouch varied from 6.7% to 73.9%. Several potential factors that favor the development of pouch polyposis have been investigated,but many remain controversial. Nevertheless,it seems certain that the age of the pouch is important. The risk appears to be 7%to 16% after 5 years,35% to 42% after 10 years,and75% after 15 years. On the other hand,only 21 cases of ileal pouch carcinoma have been recorded in the literature to date. The diagnosis of pouch carcinoma was made between 3 to 20 years(median,10 years) after pouch construction. Although the risk of malignant transformation in ileal pouches is probably low,it is not negligible,and the long-term risk cannot presently be well quantified. Regular endoscopic surveillance,especially using chromoendoscopy,is recommended.

Relevant nursing measures for the adverse reactions associated with chimeric antigen receptor T cells(CAR-T) immunotherapy: a systematic review of case reports

Objective: Cytokine release syndrome (CRS) and tumor lysis syndrome (TLS) that occur after chimeric antigen receptor T (CAR-T) cells are reinfused, which severely affect the survival and prognosis of patients. Although several articles have reported on the care of CAR-T cell immunotherapy, the quality of the study and the effectiveness of holistic nursing interventions have not been systematically reviewed. The purpose of this study was to systematically evaluate the existing holistic nursing interventions of CAR-T cell immunotherapy. Methods: A literature search for keywords was performed in PubMed, EMBASE, the Cochrane Library, CNKI, CBM, and Wanfang Data from its inception until January 2018. Studies were deemed eligible if they comprised patients with tumor receiving CAR-T cell immunotherapy, described the holistic nursing process, and were published in Chinese and English. Results: A total of 6 articles on holistic nursing interventions of CAR-T cell immunotherapy are reported, and the nursing methods and results of each article are analyzed. The quality of the studies included was medium. All nursing measures were considered effective. Conclusions: Holistic nursing programs reduce the incidence of CRS and TLS and improve the quality of life of cancer patients.

Genetic polymorphisms in genes regulating cell death and prognosis of patients with rectal cancer receiving postoperative chemoradiotherapy

Objective:The identification of biomarkers for predicting chemoradiotherapy efficacy is essential to optimize personalized treatment.This study determined the effects of genetic variations in genes involved in apoptosis,pyroptosis,and ferroptosis on the prognosis of patients with locally advanced rectal cancer receiving postoperative chemoradiotherapy(CRT).Methods:The Sequenom MassARRAY was used to detect 217 genetic variations in 40 genes from 300 patients with rectal cancer who received postoperative CRT.The associations between genetic variations and overall survival(OS)were evaluated using hazard ratios(HRs)and 95%confidence intervals(CIs)computed using a Cox proportional regression model.Functional experiments were performed to determine the functions of the arachidonate 5-lipoxygenase(ALOX5)gene and the ALOX5 rs702365 variant.Results:We detected 16 genetic polymorphisms in CASP3,CASP7,TRAILR2,GSDME,CASP4,HO-1,ALOX5,GPX4,and NRF2 that were significantly associated with OS in the additive model(P<0.05).There was a substantial cumulative effect of three genetic polymorphisms(CASP4 rs571407,ALOX5 rs2242332,and HO-1 rs17883419)on OS.Genetic variations in the CASP4 and ALOX5 gene haplotypes were associated with a higher OS.We demonstrated,for the first time,that rs702365[G]>[C]represses ALOX5 transcription and corollary experiments suggested that ALOX5 may promote colon cancer cell growth by mediating an inflammatory response.Conclusions:Polymorphisms in genes regulating cell death may play essential roles in the prognosis of patients with rectal cancer who are treated with postoperative CRT and may serve as potential genetic biomarkers for individualized treatment.

The selection was carried out by inclusion and exclusion criteria, constituting a sample of 7 articles. There have been identified the main uses of the risk concept, defining attributes, antecedents and consequences of the concept. The evaluation of the concept and nursing care to breast cancer patient on chemotherapy treatment allowed a broader understanding of the phenomenon, with emphasis on the skills and competencies in nursing care dispensed to woman on chemotherapy treatment for breast cancer.

Violence against Women with Breast Neoplasms

The aim of this study is to assess the occurrence and type of violence suffered by women with breast cancer in the High Complexity Care Unit of a municipality in the South of Minas and patients in a support group of the University of the South of Minas Gerais. For that aim, a descriptive-exploratory methodology was applied through the quantitative method. Data were collected through a semi-structured form applied in individual interviews over a period of three months. We interviewed 57 patients and among those, 20 women （35.08%） reported having experienced some form of violence at some stage of their life, and the most frequently mentioned was the psychological violence followed by physical aggression. Although it was possible to identify that violence against affected these women, complaints against the aggressor were not affected.
