Systemic Inflammation Response Index and weight loss as prognostic factors in metastatic pancreatic cancer: A concept study from the PANTHEIA-SEOM trial

BACKGROUND The prognostic value of the Systemic Inflammation Response Index(SIRI)in advanced pancreatic cancer is recognized,but its correlation with patients´nutritional status and outcomes remains unexplored.AIM To study the prognostic significance of SIRI and weight loss in metastatic pancreatic cancer.METHODS The PANTHEIA-Spanish Society of Medical Oncology(SEOM)study is a multicentric(16 Spanish hospitals),observational,longitudinal,non-interventional initiative,promoted by the SEOM Real World-Evidence work group.This pilot study sought to analyze the association between weight loss and inflammatory status as defined by SIRI.The cohort stems from a proof-of-concept pilot study conducted at one of the coordinating centers.Patients with pathologically confirmed metastatic pancreatic adenocarcinoma,treated from January 2020 to January 2023,were included.The index was calculated using the product of neutrophil and monocyte counts,divided by lymphocyte counts,obtained within 15 days before initiation chemotherapy.This study evaluated associations between overall survival(OS),SIRI and weight loss.RESULTS A total of 50 patients were included.66%of these patients were male and the median age was 66 years.Metastasis sites:36%liver,12%peritoneal carcinomatosis,10%lung,and 42%multiple locations.Regarding the first line palliative chemotherapy treatments:50%received gemcitabine plus nab-paclitaxel;28%,modified fluorouracil,leucovorin,irinotecan and oxaliplatin,and 16%were administered gemcitabine.42%had a weight loss>5%in the three months(mo)preceding diagnosis.21 patients with a SIRI≥2.3×10^(3)/L exhibited a trend towards a lower median OS compared to those with a SIRI<2.3×10^(3)/L(4 vs 18 mo;P<0.000).Among 21 patients with>5%weight loss before diagnosis,the median OS was 6 mo,in contrast to 19 mo for those who did not experience such weight loss(P=0.003).Patients with a weight loss>5%showed higher SIRI levels.This difference was statistically significant(P<0.000).For patients with a SIRI<2.3×10^(3)/L,those who did not lose>5%of their weight had an OS of 20 mo,compared to 11 mo for those who did(P<0.001).No association was found between carbohydrate antigen 19-9 levels≥1000 U/mL and weight loss.CONCLUSION A higher SIRI was correlated with decreased survival rates in patients with metastatic pancreatic cancer and associated with weight loss.An elevated SIRI is suggested as a predictor of survival,emphasizing the need for prospective validation in the upcoming PANTHEIA-SEOM study.

Risk factors,prognostic factors,and nomograms for distant metastasis in patients with diagnosed duodenal cancer:A population-based study

BACKGROUND Duodenal cancer is one of the most common subtypes of small intestinal cancer,and distant metastasis(DM)in this type of cancer still leads to poor prognosis.Although nomograms have recently been used in tumor areas,no studies have focused on the diagnostic and prognostic evaluation of DM in patients with primary duodenal cancer.AIM To develop and evaluate nomograms for predicting the risk of DM and person-alized prognosis in patients with duodenal cancer.METHODS Data on duodenal cancer patients diagnosed between 2010 and 2019 were extracted from the Surveillance,Epidemiology,and End Results database.Univariate and multivariate logistic regression analyses were used to identify independent risk factors for DM in patients with duodenal cancer,and univariate and multivariate Cox proportional hazards regression analyses were used to determine independent prognostic factors in duodenal cancer patients with DM.Two novel nomograms were established,and the results were evaluated by receiver operating characteristic(ROC)curves,calibration curves,and decision curve analysis(DCA).RESULTS A total of 2603 patients with duodenal cancer were included,of whom 457 cases(17.56%)had DM at the time of diagnosis.Logistic analysis revealed independent risk factors for DM in duodenal cancer patients,including gender,grade,tumor size,T stage,and N stage(P<0.05).Univariate and multivariate COX analyses further identified independent prognostic factors for duodenal cancer patients with DM,including age,histological type,T stage,tumor grade,tumor size,bone metastasis,chemotherapy,and surgery(P<0.05).The accuracy of the nomograms was validated in the training set,validation set,and expanded testing set using ROC curves,calibration curves,and DCA curves.The results of Kaplan-Meier survival curves(P<0.001)indicated that both nomograms accurately predicted the occurrence and prognosis of DM in patients with duodenal cancer.CONCLUSION The two nomograms are expected as effective tools for predicting DM risk in duodenal cancer patients and offering personalized prognosis predictions for those with DM,potentially enhancing clinical decision-making.

Novel prognostic factors after radical resection of hepatocellular carcinoma: Updating an old issue

In this editorial,I comment on the article by Li et al published in the recent issue of the World Journal of Gastrointestinal Surgery in 2023,investigating the role of some novel prognostic factors for early survival after radical resection of liver cancer.Liver cancer is an important burden among Asian and Western popu-lations,despite recent advances in both medicine(from virus eradication to systemic target therapies)and surgery.However,survival after proven radical surgery remains poor,with recurrences being the rule.Many prognostic scores have been developed and validated to select those patients who will best benefit from radical liver surgery,although the final general and oncological outcomes continue to be highly jeopardized.Unfortunately,no single biomarker can resolve all these issues for hepatocellular carcinoma,and it remains to be proven whether some of them main-tain predictive power in the long-term follow-up.In the ongoing era of“preci-sion”medicine,the novel prognostic markers,including immune inflammatory and nutritional indexes could be of great help in better stratify surgical candi-dates.

Prognostic Factors for Mortality in Severe Traumatic Brain Injury at HGZ 46, Villahermosa, Tabasco, Period from March 1, 2021 to December 31, 2022

Introduction: A traumatic brain injury (TBI) is caused by a forceful bump, blow, or jolt to the head or body, or by an object that pierces the skull and interrupts the normal function of the brain. Severe TBI is estimated at 73 cases per 100,000 people. The mortality of severe TBI can be reduced if a timely diagnosis and treatment of the injuries are made through prognostic factors. Objective: To determine the prognostic factors related to mortality in severe traumatic brain injury at the Hospital General de Zona No. 46. Material and Methods: Retrospective, cross-sectional and descriptive study in beneficiaries admitted to the Hospital General de Zona (HGZ) No. 46 of the Mexican Institute of Social Security (IMSS by its acronym in Spanish), with a diagnosis of severe TBI;the possible prognostic factors related to mortality of severe TBI were obtained from their records. Measures of central tendency and chi square were used for data analysis. Results: The study sample consisted of 60 subjects diagnosed with severe traumatic brain injury, of which 5 (8%) were women and 55 (92%) were men, and all 60 (100%) patients died. The average age of the sample was 26 with a standard deviation of 9 years. The variables that had a p value less than or equal to 0.05 were: Mydriasis, seizures, Hyperglycemia, Normoglycemia, Hypothermia and Hypotension. This means that these variables were associated with mortality. Conclusion: Statistical significance is demonstrated in prognostic factors of mortality in severe traumatic brain injury with p < 0.05 in the case of mydriasis, seizures, hyperglycemia, normoglycemia, hypothermia and hypotension.

Etiologies and Prognostic Factors of Dyspnea in Infants at the University Hospital Center (CHU) of Bouaké (Ivory Coast)

Identify the epidemiological characteristics, etiologies and evolutionary aspects of dyspnea in infants. This was a retrospective study of infants hospitalized for dyspnea from January 1 to December 31, 2020. The parameters studied were sex, age, origin, vaccination status, existence of underlying pathology. Underlying, the diagnosis and the evolutionary modalities. Data analysis and processing were possible using Word, Excel and EPI info version 7 software. We retained 152 infants. The sex ratio was 1.34 and the median age was 4 months. Vaccines according to expanded immunization program (EPI) were up to date in 76.32%. The main antecedents with risk identified were malnutrition, hypotrophy at birth, interventricular communication. The pathologies observed were low acute respiratory diseases in 90.79%, ENT diseases in 04.60% and cardiac diseases in 03.95%. The median length of hospitalization was 4 days. Infants who died accounted for 15.13%. The median age of infants who died was 4 months. The median time to onset of death was 1.63 days. The risk factors for death were age < 6 months (p = 0.003;CI [1.27;9.33]), outdated vaccines (p = 0.012;CI [1.18;5.17]), history with risk (p = 0.031;CI [1.02;4.54]). Dyspnea in infants remains a concern in our service. Reducing mortality involves developing procedures for the management of lower respiratory ailments, continuous staff training and strengthening the technical platform.

Prognostic Factors for Eclamptics in Intensive Cares of Two University Teaching Hospitals in Cotonou, Benin

Introduction: In Benin, the maternal mortality rate remains high and one of the main causes is preeclampsia in its complicated forms, including eclampsia. For this, treatment is most often provided in an intensive care unit by a multidisciplinary team involving obstetricians and intensive care doctors. Objective: To determine the prognostic factors of eclamptics treated in intensive care units in two university teaching hospitals in Cotonou. Patients and Method: The study was transversal descriptive and analytical with prospective collection of data from May 1 to July 31, 2022, in the intensive care units of CHU-MEL and CNHU-HKM in Cotonou. The sampling was non-probability with exhaustive recruitment of all cases of eclampsia managed in hospital intensive care units. Clinical, therapeutic and evolutionary data were studied. Data analysis was done with Epi info 7.2.1.0 software. Results: Fifty-five eclamptics were included. The incidence was 12.39%. The average age of eclamptics was 24.67 ± 1.41 years, with a reference rate of 85.45%. Primigravidae represented 52.73%. A history of eclampsia and/or high blood pressure (14.54%) was associated with mortality. Cesarean section was indicated in 85.45% and general anesthesia, was the technique used in 95.75% of cases. Eclamptic status was found in 36.37% of patients. Other poor prognostic factors were Glasgow score of less than nine (9.09%), shock (7.27%), mechanical ventilation (58.18%) and complications. Mortality was 16.36%. Conclusion: The mortality of eclamptics in the intensive care units of CHU-MEL and CNHU-HKM was high. Poor prognostic factors were a history of preeclampsia or pregnancy-induced hypertension, severity of eclampsia and complications.

Prognostic Factors for the Occurrence of Blood Exposure Accidents among Health Personnel at the Kaolack Regional Hospital (Senegal)

Caregivers are highly exposed to blood exposure accidents (BEA). The objective of our study is to determine the frequency of BEA and to identify the predictive factors for the occurrence of BEAs among caregivers at the Kaolack Regional Hospital (KRH). It is a descriptive and analytical cross-sectional study of KRH’s caregivers. The data were collected during the period from 16 to 26 April 2018. The multivariate analysis was carried out using the binary logistic regression model with a dependent variable (occurrence of blood exposure accidents) and 5 explanatory variables (sex, age, service of belonging, professional category and seniority in the profession). A total of 115 caregivers were surveyed out of 144. It is noted that 68 caregivers (59.1%) have had at least one BEA in the previous 12 months. The age of caregivers significantly reduces the risk of developing a BEA (p = 0.004, CI [0.04 - 0.21]);belonging to the age group [20 - 40 years] increases the risk of a BEA by 6.66. Sex significantly influences the occurrence of BEA with a (p = 0.013, CI [1.47 - 19.4]);men are 5 times more likely to develop BEA. The risk of a BEA occurring varies according to the professional category. Senior health technicians have a significantly 50 times lower risk of occurrence of a BEA (p = 0.007, CI [0.00 - 0.24)]. Nurses and midwives have a 5.8 lower risk of developing BEAs (p = 0.031, CI [0.03 - 0.75]). The risk of occurrence of BEAs varies according to the service of belonging;Medicine service caregivers have a significantly 50-fold lower risk of developing BEAs (p = 0.004, CI [0.00 - 0.17]). The identified risk factors will be used to better guide our BEAs prevention interventions.

Analysis of the personalized treatment and the relevant prognostic factors in children with medulloblastoma

Purpose:The present study summarized cases of children(n=32)with medulloblastoma(MB)who were treated using stratified therapy based on risk grading and also discussed the factors affecting prognosis.Methods:According to the risk stratification criteria,the cases were divided into the following four risk groups:low,standard,high,and very high.The 5-year overall survival(OS)and progression-free survival(PFS)rates were summarized.Further,the effects on the prognosis of tumor size,tumor stage,degree of resection,treatment mode,metastatic recurrence,molecular typing,and risk stratification were analyzed.Results:In the present study,following surgery,3 cases abandoned radiotherapy(RT)and chemotherapy(CHT),7 cases(<3 years of age)received only CHT,and 22 cases received combined RT and CHT.Total and near-total tumor resections were performed in 29 cases(90.6%).Subtotal resections were performed in 3 cases,and there were no surgery-related deaths.The average follow-up duration was 47 months.The average 5-year PFS and OS rates were 57.3%±7.2%and 68.7%±8.6%,respectively.The OS and PFS rates were significantly correlated with tumor-risk stratification,molecular staging,tumor stage,treatment mode,and recurrence after surgery(p<0.01).The degree of tumor resection,pathological type,and the presence of preoperative implantation were secondary factors affecting the prognosis(p<0.05).Age was correlated with the PFS rate.There was no correlation between age/tumor location/tumor size and prognosis(p>0.05).Favorable prognostic factors in the low-and standard-risk groups were stage M0,wingless-type MB,postoperative RT combined with CHT,no postoperative recurrence,age≥3 years,and total tumor resection.Conclusions:Personalized treatment strategies based on the risk stratification of MB and postoperative stratified comprehensive treatment could help improve the prognosis for MB.

Prognostic factors in Chinese patients with metastatic castration-resistant prostate cancer treated with docetaxel-based chemotherapy

This study aims to evaluate the potential value of patient characteristics in predicting overall survival （OS） in patients with metastatic castration-resistant prostate cancer （mCRPC） treated with docetaxel-based thermotherapy. A total of 115 patients with mCRPC undergoing a docetaxel q3w regimen were enrolled in this study. A survival analysis was performed using the Kaplan-Meier method. Cox proportional hazards models were used to evaluate the prognostic value of all covariates for OS. OS was also analysed after stratifying patients according to the results of multivariate analysis. The median OS for the entire cohort was 17.0 months. The multivariate analysis showed that the prostate-specific antigen doubling time （PSADT）, baseline haemoglobin （Hb） concentration, alkaline phosphatase （ALP） concentration, cycles of chemotherapy and time to castration resistance were independent prognostic factors of OS. According to the presence of PSADT 〈46.3 days and baseline ALP/〉 110 IU 1-1, all patients were divided into three risk groups： low-risk group （no risk factors）, intermediate-risk group （one risk factor） and high-risk group （two risk factors）. Median OSs for patients in low-, intermediate- and high-risk groups were 28.0 months （95% Ch 23.8-32.2）, 21.0 months （95% Ch 18.9-23.1） and 11.0 months （95% Ch 7.6-14.4）, respectively （P〈O.O01）. In conclusion, PSADT, baseline Hb concentration, ALP concentration, cycles of chemotherapy and time to castration resistance were independent prognostic factors of OS in Chinese patients with mCRPC treated with docetaxel. PSADT combined with the baseline ALP concentration could be a useful risk stratification parameter for evaluating survival outcomes.

Combined vascular resection and analysis of prognostic factors for hilar cholangiocarcinoma

BACKGROUND： Hilar cholangiocarcinoma （HCCA） is a devastating malignancy arising from the bifurcation of the hepatic duct, whether combined vascular resection benefits HCCA patients is controversial. This study was undertaken to assess the effect of combined vascular resection in HCCA patients and to analyze the prognostic factors.

Bone metastases from hepatocellular carcinoma:clinical features and prognostic factors

BACKGROUND: Bone metastases (BMs) from hepatocellular carcinoma (HCC) is an increasingly common disease in Asia. We assessed the clinical features, prognostic factors, and differences in outcomes related to BMs among patients with different treatments for HCC. METHODS: Forty-three consecutive patients who were diagnosed with BMs from HCC between January 2010 and December 2014 were retrospectively enrolled. The clinical features were identified, the impacts of prognostic factors on survival were statistically analyzed, and clinical data were compared. RESULTS: The median patient age was 54 years; 38 patients were male and 5 female. The most common site for BMs was the trunk (69.3%). BMs with extension to the soft tissue were found in 14 patients (32.5%). Most (90.7%) of the lesions were mixed osteolytic and osteoblastic, and most (69.8%) patients presented with multiple BMs. The median survival after BMs diagnosis was 11 months. In multivariate analyses, survival after BM diagnosis was correlated with Karnofsky performance status (P=0.008) and the Child-Pugh classification (P<0.001); BM-free survival was correlated with progression beyond the University of California San Francisco criteria (P<0.001) and treatment of primary tumors (P<0.001). BMs with extension to soft tissue were less common in liver transplantation patients. During metastasis, the control of intrahepatic tumors was improved in liver transplantation and hepatectomy patients, compared to conservatively treated patients. CONCLUSIONS: The independent prognostic factors of survival after diagnosis of BMs were the Karnofsky performance status and Child-Pugh classification. HCC patients developed BMs may also benefit from liver transplantation or hepatectomy.

Prognostic factors and therapeutic effects of different treatment modalities for colorectal cancer liver metastases

BACKGROUND Colorectal cancer(CRC)is one of the most common malignant tumors in China,and the liver is the most common metastatic site in patients with advanced CRC.Hepatectomy is the gold standard treatment for colorectal liver metastases.For patients who cannot undergo radical resection of liver metastases for various reasons,ablation therapy,interventional therapy,and systemic chemotherapy can be used to improve their quality of life and prolong their survival time.AIM To explore the prognostic factors and treatments of liver metastases of CRC.METHODS A retrospective analysis was conducted on 87 patients with liver metastases from CRC treated at the Liaoning Cancer Hospital and Institute between January 2005 and March 2011.According to different treatments,the patients were divided into the following four groups:Surgical resection group(36 patients);ablation group(23 patients);intervention group(15 patients);and drug group(13 patients).The clinicopathological data and postoperative survival of the four groups were analyzed.The Kaplan-Meier method was used for survival analysis,and the Cox proportional hazards regression model was used for multivariate analysis.RESULTS The median survival time of the 87 patients was 38.747±3.062 mo,and the 1-and 3-year survival rates were 87.5%and 53.1%,respectively.The Cox proportional hazards model showed that the following factors were independent factors affecting prognosis:The degree of tumor differentiation,the number of metastases,the size of metastases,and whether the metastases are close to great vessels.The results of treatment factor analysis showed that the effect of surgical treatment was better than that of drugs,intervention,or ablation alone,and the median survival time was 48.83±4.36 mo.The drug group had the worst prognosis,with a median survival time of only 13.5±0.7 mo(P<0.05).For patients with liver metastases of CRC near the great vessels,the median survival time(27.3 mo)of patients undergoing surgical resection was better than that of patients using other treatments(20.6 mo)(P<0.05).CONCLUSION Patients with a low degree of primary tumor differentiation,multiple liver metastases(number of tumors>4),and maximum diameter of liver metastases>5 cm have a poor prognosis.Among drug therapy,intervention,ablation,and surgical treatment options,surgical treatment is the first choice for liver metastases.When liver metastases are close to great vessels,surgical treatment is significantly better than drug therapy,intervention,and ablation alone.

Clinical features, survival and prognostic factors of primary testicular diffuse large B-cell lymphoma

Objective： To assess the clinical features, survival and prognostic factors of primary testicular diffuse large B-cell lymphoma （DLBCL）. Methods： A retrospective study of 37 patients with primary testicular DLBCL was carried out from November 2003 to May 2012. Their clinical features, survival and prognostic factors were analyzed. Results： During a median follow-up period of 39.8 months （5.4-93.0 months）, the median progression-free survival （PFS） was 26.2 months （95% CI：0-65 months） and the 3-year overall survival （OS） rate was 78.4%. Within the whole cohort, the factors significantly associated with a superior PFS were limited stage （stage Ⅰ/Ⅱ）, lactate dehydrogenase （LDH） ≤245 U/L, international prognostic index （IPI） ≤1, primary tumor diameter 〈7.5 cm, and patients who had complete response （CR） and received doxoruhicin-contained chemotherapy （P〈0.05）. There was a trend toward superior outcome for patients who received combined therapy （surgery/ chemotherapy/radiotherapy） （P=0.055）. Patients who had CR, primary tumor diameter 〈7.5 cm and IPI score ≤1 were significantly associated with longer PFS at multivariate analysis. Conclusions： Primary testicular DLBCL had poorer survival. CR, primary tumor diameter and IPI were independent prognostic factors. The combined therapy of orchectomy, doxorubicin-contained chemotherapy and contralateral testicular radiotherapy （RT） seemed to improve survival.

Downregulation of orosomucoid 2 acts as a prognostic factor associated with cancer-promoting pathways in liver cancer

BACKGROUND Liver cancer has a high mortality and morbidity rate throughout the world.In clinical practice,the prognosis of liver cancer patients is poor,and the complex reasons contribute to treatment failures,including fibrosis,hepatitis viral infection,drug resistance and metastasis.Thus,screening novel prognostic biomarkers is of great importance for guiding liver cancer therapy.Orosomucoid genes(ORMs)encode acute phase plasma proteins,including orosomucoid 1(ORM1)and ORM2.Previous studies showed their upregulation upon inflammation,but the specific function of ORMs has not yet been determined,especially in the development of liver cancer.AIM To determine the expression of ORMs and their potential function in liver cancer.METHODS Analysis of the expression of ORMs in different human tissues was performed on data from the HPA RNA-seq normal tissues project.The expression ratio of ORMs was determined using the HCCDB database,including the ratio between liver cancer and other cancers,normal liver and other normal tissues,liver cancer and adjacent normal liver tissues.Analysis of ORM expression in different cancer types was performed using The Cancer Genome Atlas and TIMER database.The expression of ORMs in liver tumor tissues and adjacent normal tissues were further confirmed using Gene Expression Omnibus data,including GSE36376 and GSE14520.The 10-year overall survival(OS),progression-free survival(PFS)and relapse-free survival(RFS)rates between high and low ORM expression groups in liver cancer patients were determined using the Kaplan-Meier plotter tool.Gene Set Enrichment Analysis(GSEA)was employed to explore the ORM2-associated signaling network.Correlations between ORM2 expression and tumor purity or the infiltration level of macrophages in liver tumor tissues were determined using the TIMER database.The correlation between ORM2 gene levels,tumor-associated macrophage(TAM)markers(including CD68 and TGFβ1)and T cell immunosuppression(including CTLA4 and PD-1)in liver tumor tissues and liver GTEx was determined using the GEPIA database.RESULTS ORM1 and ORM2 were highly expressed in normal liver and liver tumor tissues.ORM1 and ORM2 expression was significantly decreased in liver tumor tissues compared with adjacent normal tissues,and similar results were also noted in cholangiocarcinoma,esophageal carcinoma,and lung squamous cell carcinoma.Further analysis of the Gene Expression Omnibus Database also confirmed the downregulation of ORM1 and ORM2 in liver tumors.Survival analysis showed that the high ORM2 group had better survival rates in OS,PFS and RFS.ORM1 only represented better performance in PFS,but not in OS or RFS.GSEA analysis of ORM2 from The Cancer Genome Atlas liver cancer data identified that ORM2 positively associated with the G2/M checkpoint,E2F target signaling,as well as Wnt/β-catenin and Hedgehog signaling.Moreover,apoptosis,IFN-αresponses,IFN-γresponses and humoral immune responses were upregulated in the ORM2 high group.ORM2 expression was negatively correlated with the macrophage infiltration level,CD68,TGFβ1,CTLA4 and PD-1 levels.CONCLUSION The results showed that ORM1 and ORM2 were highly expressed specifically in liver tissues,whereas ORM1 and ORM2 were downregulated in liver tumor tissues.ORM2 is a better prognostic factor for liver cancer.Furthermore,ORM2 is closely associated with cancer-promoting pathways.

Risk Factors and Prognostic Factors of Acute Kidney Injury in Children: a Retrospective Study between 2003 and 2013

Summary： Recent report on epidemiology of acute kidney injury （AKI） is lacking for Chinese children. We aimed to investigate the risk factors for stage and prognostic factors for renal recovery in hospital- ized children. Pediatric patients （〈18 years old） admitted during 2003 to 2013 were enrolled in this study. AKI was defined and staged using Kidney Disease Improving Global Outcomes （KDIGO） crite- ria. Logistic regression analysis was performed to determine the risk factors and prognostic factors. The morbidity of pediatric AKI was 0.31% （205/65 237）. There were 45 （22.0%） cases in stage I, 30 （14.6%） cases in stage II and 130 （63.4%） cases in stage Ill. The majority of etiologies were intrinsic renal defects （85.4%）. Age, weight, vomit, etiology, blood urea nitrogen （BUN） at admission and sev- eral blood gas measurements were associated with AKI stage III. Age （OR=0.894; 95% CI, 0.832- 0.962; P=0.003）, vomit （OR=2.375; 95% CI, 1.058-5.333; P=0.036） and BUN at admission （OR=1.135;95% CI, 1.085-1.187; P〈0.001） were identified as independent risk factors for AKI stage Ill. After treatment, 172 （83.9%） patients achieved complete or partial recovery. The mortality was 3.9%. Variables were found as prognostic factors for renal recovery, such as age, stage, hospital stay, BUN at discharge, white blood cells, red blood cells, platelets （PLTs）, blood pH and urine blood. Among them, AKI stage（stage III vs. stage I ; OR, 6.506; 95% CI, 1.640-25.816; P=0.008）, BUN at discharge （OR, 0.918; 95% CI, 0.856-0.984; P=0.016） and PLTs （OR, 1.007; 95% CI, 1.001- 1.013; P=0.027） were identified as independent prognostic factors. AKI is still common in Chinese hos- pitalized children. Identified risk factors and prognostic factors provide guiding information for clinical management of AKI.

Prognostic factors and predictors of postoperative adjuvant transcatheter arterial chemoembolization benefit in patients with resected hepatocellular carcinoma

BACKGROUND Postoperative adjuvant transcatheter arterial chemoembolization (PA-TACE) has improved overall survival (OS) in patients with hepatocellular carcinoma (HCC).However,the prognostic and predictive factors remain unclear.AIM To assess the prognostic factors and the predictors of PA-TACE benefit for OS in patients with resected HCC.METHODS Univariate and multivariate analyses were performed to identify the potential prognostic factors for OS.In order to assess the predictive factors of PA-TACE benefit,the interaction variables between treatments for each subgroup were evaluated using the Cox proportional hazards regression model.RESULTS A total of 378 patients (PA-TACE vs surgery alone,189:189) from three centerswere included after a propensity-score 1:1 matching analysis.Compared to the group receiving surgery alone,PA-TACE prolonged the OS rate in patients with resected HCC (P <0.001).The Barcelona Clinic Liver Cancer system and ferritinto-hemoglobin ratio (FHR) were used as the prognostic factors for OS in both groups.Age (P=0.023) and microscopic vascular invasion (MVI)(P=0.002) were also identified in the PA-TACE group,while gender (P=0.027),hepatitis B virus(P=0.034) and albumin-bilirubin grade (P=0.027) were also selected in the surgery alone group.In addition,PA-TACE resulted in longer OS than surgery alone across subgroups [all hazard ratios (PA-TACE-to-surgery alone)<1].Notably,a significantly prolonged OS following PA-TACE was observed in patients with high FHR (P=0.038) and without MVI (P=0.048).CONCLUSION FHR and Barcelona Clinic Liver Cancer stages were regarded as prognostic factors for OS.Moreover,high FHR and the absence of MVI were important predictive factors,which can be used to assist clinicians in selecting which patients could achieve a better OS with PA-TACE.

Outcome and prognostic factors in 110 consecutive patients with primary uterine leiomyosarcoma:A Rare Cancer Network study

Objective： Primary uterine leiomyosarcomas （ULMS） are rare, and the optimal treatment is controversial. We aimed to assess the outcome and prognostic factors in a multicenter population of women treated for primary ULMS. Methods： We retrospectively collected data of 110 women treated in 19 institutions of the Rare Cancer Network （RCN）. Inclusion criteria consisted of a pathology report confirming the diagnosis of ULMS, aged 18-80 years, complete International Federation of Gynecology and Obstetrics （FIGO） stage information, complete information on treatment, and a minimum follow-up of 6 months. Local control （LC） and locoregional control （LRC）, overall survival （OS） and disease-free survival （DFS） rates were computed using the Kaplan-Meier method. Univariate analysis was implemented using the log rank test, and multivariate analysis using the Cox model. Results： All patients underwent surgery. Seventy-five patients （68%） received adjuvant radiotherapy （RT）, including brachytherapy in 18 （I 6%）. Seventeen patients （15 %） received adjuvant chemotherapy. Median follow-up was 58 （range, 6-240） months. Five-year OS and DFS rates were 50% and 34%, and LC and LRC rates were 88% and 72%, respectively. On multivariate analysis, independent favorable prognostic factors were younger age, FIGO stage I, small tumor size, previous uterine disease, and no vascular invasion for OS and DFS. FIGO stage was the only favorable factor influencing LRC. Adjuvant local or systemic treatments did not improve the outcomes. Eight patients treated with RT presented a grade 3 acute toxicity, and only one patient with grade 3 late toxicity. Conclusions： In this large population of primary ULMS patients, we found good results in terms of LC and LRC. Nevertheless, OS remains poor, mainly due to the occurrence of distant metastases. An early diagnosis seemed to improve the prognosis of the patients. Adjuvant local or systemic treatments, or more aggressive surgical procedures such as the Wertheim procedure, did not seem to impact the outcome.

Outcomes and prognostic factors of patients with stage? ⅠB and? ⅡA pancreatic cancer according to the 8^(th) edition American Joint Committee on Cancer criteria

AIM To evaluate the changes in the 8^(th) edition American Joint Committee on Cancer(AJCC) for defining stage?ⅠB and?ⅡA pancreatic cancer and identify their prognostic factors.METHODS Pancreatic cancer patients were selected from the Surveillance Epidemiology and End Results database(1973-2013). The enrolled patients were divided into?ⅠB and?ⅡA groups based on tumor size according to the 8^(th) edition AJCC criteria. Clinical characteristics, including age, gender, race, tumor size, primary site, and grade were summarized. Univariate and multivariate analyses were performed to explore the prognostic factors of the?ⅠB and?ⅡA stages of pancreatic cancer under new criteria.RESULTS A total of 1349 pancreatic cancer patients were included. More patients had stage?ⅠB rather than stage?ⅡA. Stage?ⅠB tumors(54.85%) were mainly located in the head of the pancreas, while stage?ⅡA tumors were more often located in the tail and head of the pancreas(35.21% and 31.75%, respectively). The survival time of stage?ⅠB and?ⅡA patients had no significant difference. Univariate and multivariate analyses indicated that the prognostic factors of survival for stage?ⅠB and?ⅡA patients were different. for stage?ⅠB patients, age and primary site were the independent prognostic factors; for stage?ⅡA patients, age and grade were the independent prognostic factors. The risk of death was lower among patients aged ≤ 65 years than those aged > 65 years.CONCLUSION The prognostic factors for stage?ⅠB and?ⅡA patients are different, but age is the independent prognostic factor for all patients. The survival time of stage?ⅠB and?ⅡA patients has no significant difference.

Prognostic factors of minimally invasive surgery for gastric cancer: Does robotic gastrectomy bring oncological benefit?

BACKGROUND Gastric cancer is the third leading cause of cancer-related death worldwide and surgical resection remains the sole curative treatment for gastric cancer.Minimally invasive gastrectomy including laparoscopic and robotic approaches has been increasingly used in a few decades.Thus far,only a few reports have investigated the oncological outcomes following minimally invasive gastrectomy.AIM To determine the 5-year survival following minimally invasive gastrectomy for gastric cancer and identify prognostic predictors.METHODS This retrospective cohort study identified 939 patients who underwent gastrectomy for gastric cancer during the study period.After excluding 125 patients with non-curative surgery(n=77),other synchronous cancer(n=2),remnant gastric cancer(n=25),insufficient physical function(n=13),and open gastrectomy(n=8),a total of 814 consecutive patients with primary gastric cancer who underwent minimally invasive R0 gastrectomy at our institution between 2009 and 2014 were retrospectively examined.Accordingly,5-year overall and recurrence-free survival were analyzed using the Kaplan–Meier method with the log-rank test and Cox regression analyses,while factors associated with survival were determined using multivariate analysis.RESULTS Our analysis showed that age>65 years,American Society of Anesthesiologists(ASA)physical status 3,total or proximal gastrectomy,and pathological T4 and N positive status were independent predictors of both 5-year overall and recurrencefree survival.Accordingly,the included patients had a 5-year overall and recurrence-free survival of 80.3%and 78.2%,respectively.Among the 814 patients,157(19.3%)underwent robotic gastrectomy,while 308(37.2%)were diagnosed with pathological stage II or III disease.Notably,our findings showed that robotic gastrectomy was an independent positive predictor for recurrence-free survival in patients with pathological stage II/III[hazard ratio:0.56(0.33-0.96),P=0.035].Comparison of recurrence-free survival between the robotic and laparoscopic approach using propensity score matching analysis verified that the robotic group had less morbidity(P=0.005).CONCLUSION Age,ASA status,gastrectomy type,and pathological T and N status were prognostic factors of minimally invasive gastrectomy,with the robot approach possibly improving long-term outcomes of advanced gastric cancer.
