ABSTRACT
Abstract Objective The purpose of this study was to evaluate the clinical-epidemiological profile, associated risk factors and clinical outcomes of patients with acute myeloid leukemia (AML), identifying the main causes of morbidity and mortality and overall survival rate of patients at five years of follow-up. Method This was a retrospective cohort study evaluating the prognosis and clinical outcomes of 222 patients diagnosed with AML at three large hematology centers in Ceará (northeastern Brazil) over a period of five years. Results The mean age at diagnosis was 44.1 ± 16 years, with a female prevalence of 1.3:1. No additional relevant risk factors associated with the development of AML were found, except for the well-established cytogenetic assessment. The overall 5-year survival rate was 39.4% (95%CI: 35.47 - 42.17). The main causes of death were disease progression (37.72%; n = 84) and sepsis (31.58%; n = 70). Conclusion The clinical outcomes in our sample of AML patients were similar to those of other reported groups. Disease progression and infection were the main causes of death. Access to diagnostic flow cytometry and karyotyping was greater in our sample than in the national average. As expected, overall survival differed significantly according to the risk, as determined by cytogenetic testing.

Objective:To evaluate the prognostic significance of inflammatory biomarkers,prognostic nutritional index and clinicopathological characteristics in tongue squamous cell carcinoma(TSCC)patients who underwent cervical dissection.Methods:The retrospective cohort study consisted of 297 patients undergoing tumor resection for TSCC between January 2017 and July 2018.The study population was divided into the training set and validation set by 7:3 randomly.The peripheral blood indices of interest were preoperative neutrophil-to-lymphocyte ratio(NLR),lymphocyte-to-monocyte ratio(LMR),platelet-to-lymphocyte ratio(PLR),systemic immune-inflammation index(SII),systemic inflammation score(SIS)and prognostic nutritional index(PNI).Kaplan-Meier survival analysis and multivariable Cox regression analysis were used to evaluate independent prognostic factors for overall survival(OS)and disease-specific survival(DSS).The nomogram's accuracy was internally validated using concordance index,receiver operating characteristic(ROC)curve,area under the curve(AUC),calibration plot and decision curve analysis.Results:According to the univariate Cox regression analysis,clinical TNM stage,clinical T category,clinical N category,differentiation grade,depth of invasion(DOI),tumor size and pre-treatment PNI were the prognostic factors of TSCC.Multivariate Cox regression analysis revealed that pre-treatment PNI,clinical N category,DOI and tumor size were independent prognostic factors for OS or DSS(P<0.05).Positive neck nodal status(N≥1),PNI≤50.65 and DOI>2.4 cm were associated with the poorer 5-year OS,while a positive neck nodal status(N≥1),PNI≤50.65 and tumor size>3.4 cm were associated with poorer 5-year DSS.The concordance index of the nomograms based on independent prognostic factors was 0.708(95%CI,0.625-0.791)for OS and 0.717(95%CI,0.600-0.834)for DSS.The C-indexes for external validation of OS and DSS were 0.659(95%CI,0.550-0.767)and 0.780(95%CI,0.669-0.890),respectively.The 1-,3-and 5-year time-dependent ROC analyses(AUC=0.66,0.71 and 0.72,and AUC=0.68,0.77 and 0.79,respec-tively)of the nomogram for the OS and DSS pronounced robust discriminative ability of the model.The calibration curves showed good agreement between the predicted and actual observations of OS and DSS,while the decision curve confirmed its pronounced application value.Conclusion:Pre-treatment PNI,clinical N category,DOI and tumor size can potentially be used to predict OS and DSS of patients with TSCC.The prognostic nomogram based on these variables exhibited good accurary in predicting OS and DSS in patients with TSCC who underwent cervical dissection.They are effective tools for predicting sur-vival and helps to choose appropriate treatment strategies to improve the prognosis.
ABSTRACT
Objective To explore the relationship between p-FGFR1Y654 expression and clinical pathological characteristics of esophageal squamous cell carcinoma patients and its prognostic value.Methods Tumor tissue samples from 103 cases of esophageal squamous cell carcinoma and 58 normal esophageal tissues were surgically collected in the General Hospital of Western Theater between January 2017 and July 2020.The expression of p-FGFR1Y654 in the tissues was detected using immunohistochemical assay,and its correlation with relevant clinicopathological parameters and prognosis was analyzed.Results The expression of p-FGFR1Y654 in esophageal squamous cell carcinoma tissues was significantly higher than that in normal tissue(P<0.01).Its expression level was closely related to overall survival(OS,P<0.05),but not related to age,gender,tumor stage or tumor size.Multivariate COX regression analysis showed that N-stage was identified as an independent prognostic factor for recurrence free survival(RFS)in esophageal squamous cell carcinoma patients.Survival analysis indicated that patients with low expression of p-FGFR1Y654 had significantly higher RFS and OS than those with high expression(P=0.032,95%CI:1.08~4.65;P=0.004,95%CI:2.14-11.51).Conclusion p-FGFR1Y654 is highly expressed in esophageal squamous cell carcinoma tissue,and is associated with poor prognosis in these patients.p-FGFR1Y654 may be a potential therapeutic target for esophageal squamous cell carcinoma.
ABSTRACT
Objective·To establish a prognostic model for the overall survival(OS)of hepatocellular carcinoma(HCC)based on mitochondrial genes and clinical information.Methods·The gene expression and the clinical data of 369 HCC patients and 50 controls with normal liver were downloaded from The Cancer Genome Atlas(TCGA)database.The nuclear-encoded mitochondrial genes(NEMGs)were obtained from the MitoCarta3.0 database.The"DESeq2"R package and univariate Cox analysis were used to select NEMGs[ubiquinol cytochrome C reductase hinge protein(UQCRH),ATP citrate lyase(ACLY),phosphoenolpyruvate carboxykinase 2(PCK2),Bcl-2 homologous antagonist/killer1(BAK1),Bcl-2-associated X protein(BAX)and Bcl-2/adenovirus E1B interacting protein 3-like(BNIP3L)]in HCC that were associated with OS of HCC and participated in dysregulation of oxidative phosphorylation,tricarboxylic acid cycle and cell apoptosis.Multivariate Cox analysis was applied to select independent risk factors for OS of HCC.A comprehensive prognostic model and a prognostic nomogram with 6-NEMG risk characteristics and TNM staging were established.By using the median of prognostic scores as a cut-off,HCC patients were classified into low-risk and high-risk group.Kaplan-Meier survival curve analysis was conducted and log-rank test was performed to evaluate the survival rates between the low-risk and high-risk group.The area under the curve(AUC)values of receiver operating characteristic(ROC)curve were calculated via using the"timeROC"package.The prognostic model for HCC was validated by using the GEO HCC cohort(GSE14520)for 1,3 and 5 years.Finally,the relative expression level of 6-NEMG was validated in 34 clinical samples of HCC from Xinhua Hospital,Shanghai Jiao Tong University School of Medicine by using real-time quantitative polymerase chain reaction(qPCR)method.Results·Compared to 6-NEMG risk signature only(AUCs for 1,3 and 5 years were 0.77,0.66 and 0.65,respectively)or TNM stage only(AUCs for 1,3 and 5 years were 0.66,0.67 and 0.63,respectively),ROC curve analysis showed that this integrated prognostic model displayed better predictive performance for 1-year(AUC,0.78),3-year(AUC,0.73)and 5-year(AUC,0.69)OS of HCC.The Kaplan-Meier survival curve analysis showed that the OS of HCC patients in the high-risk group was significantly worse than that in the low-risk group(P=0.001).In addition,predictive performance of the prognostic model(AUC for 1,3 and 5 years is 0.67,0.66 and 0.74,respectively)and prognostic differences between the high-risk and low-risk group(P=0.001)were further validated in GEO(GSE14520)external cohort,and these results were consistent with the TCGA data.In addition to BNIP3L,dysregulation of five other NEMGs in the clinical HCC cohort was validated.The correlation analysis in GSE14520 and HCC clinical cohort showed a positive correlation between prognosis score and the size and number of tumors.Conclusion·A new prognostic model that combines 6-NEMG risk characteristics with TNM staging for predicting OS in HCC patients was constructed and validated.This model may help improve the prognosis prediction of HCC patients.
ABSTRACT
Objective:To develop and verify a nomogram to predict disease-free survival(DFS)and overall survival(OS)for patients undergoing cervical cancer surgery,which may provide reference for evaluating the prognosis of cervical cancer patients undergoing surgery.Methods:The clinical,pathological and follow-up data of patients who underwent radical operation for cervical cancer in Xijing Hospital,Air Force Medical University from March 2013 to October 2018 were analyzed retrospectively.Based on Cox regression analysis,Bayesian Informa-tion Criterion(BIC)backward stepwise selection method and R square screening variables,Net Reclassification Index(NRI)and Integrated Discrimination Improvement(IDI)were used to compare the predictive efficiency of the model,and a nomogram with better predictive efficiency was selected.The consistency index(C-index)and the receiver operating characteristic curve(ROC)were used to test the efficiency of the nomogram.Results:A total of 950 patients with cervical cancer were enrolled in this study.The risk factors for constructing the DFS nomogram were FIGO stage(2018),parametrium invasion,invasion depth,and maximum tumor diameter.The C-index for DFS in the training cohort and the verification cohort were 0.754 and 0.720,respectively.The area under ROC of the training cohort for 1-,3-and 5-years was 0.74(95%CI 0.65-0.82),0.77(95%CI 0.71-0.83)and 0.79(95%CI0.74-0.85),and the areas under ROC of verification cohort 1-,3-and 5-years were 0.72(95%CI 0.58-0.87),0.75(95%CI 0.64-0.86)and 0.72(95%CI 0.61-0.84),respectively.The risk factors for con-structing the OS nomogram were FIGO stage(2018),histological type,LVSI,parametrium invasion,surgical mar-gin,and invasion depth.The C-index for OS in the training cohort and the verification cohort were 0.737 and 0.759,respectively.The area under ROC of the 3-and 5-year training cohort were 0.76(95%CI 0.69-0.83)and 0.78(95%CI 0.72-0.84),and the areas under ROC of verification cohort 3-and 5-years were 0.76(95%CI 0.65-0.87)and 0.79(95%CI 0.69-0.88),respectively.Conclusions:This study is based on real-world big data to construct nomogram of DFS for 1,3,and 5 years and OS for 3,and 5 years for cervical cancer,which have ideal predictive effects and help clinical physicians correctly evaluate the prognosis of cervical cancer surgery patients.It provides strong reference basis for diagnosis,treatment,and prognosis evaluation.
ABSTRACT
BACKGROUND:Haploidentical hematopoietic stem cell transplantation is associated with a higher rate of graft rejection and therefore often requires a higher CD34+ cell dose,but the findings reported in existing studies regarding the relationship between CD34+ cell dose and study endpoints after allogeneic hematopoietic stem cell transplantation are controversial. OBJECTIVE:To investigate the effect of CD34+ cell dose on clinical outcomes of haploidentical hematopoietic stem cell transplantation for malignant hematological diseases. METHODS:135 patients who underwent haploidentical hematopoietic stem cell transplantation at Hematopoietic Stem Cell Transplantation Center,Department of Hematology,First Affiliated Hospital of Zhengzhou University between January 2019 and December 2021 were included.Combining the results of previous studies and our center's experience,the cohort was divided into two groups using a CD34+ cell count of 5.0×106/kg as the cut-off point.Clinical outcomes related to graft implantation,relapse incidence,non-relapse mortality,overall survival and progression-free survival were evaluated in both groups. RESULTS AND CONCLUSION:(1)CD34+ cell dose correlated with platelet engraftment,with platelets implanted earlier in the high-dose group than in the low-dose group(14 days vs.16 days,P=0.013).(2)There was no significant difference in 3-year overall survival between the two groups(67.5%vs.53.8%,P=0.257);nor was there a significant difference in progression-free survival between the two groups(65.6%vs.44.2%,P=0.106),but stratified analysis based on disease risk index revealed an association with elevated 3-year progression-free survival in the high-dose group among low-risk patients(72.0%vs.49.3%,P=0.036).(3)The cumulative 3-year relapse incidence was smaller in the high-dose group than in the low-dose group(16.0%vs.33.5%,P=0.05).(4)The rate of non-relapse mortality within 100 days was greater in the high-dose group than in the low-dose group,but there was no significant difference(17.3%vs.6.7%,P=0.070);stratified analysis revealed that non-relapse mortality within 100 days was significantly higher in the high-dose group than in the low-dose group(20.0%vs.3.3%,P=0.046).(5)In conclusion,CD34+ cell doses>5.0×106/kg promote early platelet implantation,improve 3-year progression-free survival in low-risk patients at transplantation and reduce the cumulative relapse incidence.However,in high-risk patients,high-dose CD34+ cells result in increased non-relapse mortality within 100 days after transplantation,which is considered to be possibly associated with an increased occurrence of severe acute graft versus host disease in the early post-transplantation period.Therefore,it is considered that graft versus host disease monitoring should be enhanced in patients who transfused high-dose CD34+ cells.
ABSTRACT
Objective:To assess the predictive value of aspartate aminotransferase-to-alanine amino-transferase ratio (DRR) on overall survival of patients with pancreatic ductal adenocarcinoma (PDAC) who underwent radical pancreaticoduodenectomy.Methods:A retrospective analysis was performed on the clinical data of 137 patients who underwent radical pancreaticoduodenectomy and were diagnosed with PDAC postoperatively at the Chinese PLA General Hospital from January 2015 to December 2020. There were 97 male and 40 female patients, with an average age of (58±10) years old. The patients were grouped according to the optimal survival risk cutoff value of DRR, and the differences in key clinical and pathological indicators between the groups were compared. Kaplan-Meier method was used for survival analysis, and log-rank test was used for comparison of survival rates. Multivariate Cox analysis was performed to evaluate the prognostic factors affecting survival.Results:The 137 PDAC patients were divided into two groups based on the optimal cutoff value of DRR, namely 1.1: DRR≥1.1 was defined as the high-DRR group ( n=29), and DRR<1.1 was defined as the low-DRR group ( n=108). The cumulative survival rate of the low-DRR group was better than that of the high-DRR group, and the difference was statistically significant ( P=0.003). The results of the multivariate Cox regression analysis showed that DRR≥1.1 ( HR=2.485, 95% CI: 1.449-4.261, P=0.001), preoperative biliary drainage ( HR=1.845, 95% CI: 1.030-3.306, P=0.039), lymph node metastasis N2 stage ( HR=2.240, 95% CI: 1.123-4.470, P=0.022), high tumor differentiation ( HR=2.001, 95% CI: 1.279-3.129, P=0.002), and intravascular cancer emboli ( HR=2.240, 95% CI: 1.123-4.470, P=0.022) were risk factors for poor overall survival in PDAC patients who underwent radical pancreaticoduodenectomy. Conclusion:DRR has predictive value for overall survival after surgery in PDAC patients undergoing radical pancreatoduodenectomy. A DRR of 1.1 or greater is a risk factor for poor overall survival after surgery in PDAC patients.
ABSTRACT
Objective:To verify the predictive value of the Second Revision of the International Staging System (R2-ISS) in newly diagnosed patients with multiple myeloma (MM) who underwent first-line autologous hematopoietic stem cell transplantation (ASCT) in a new drug era in China.Methods:This multicenter retrospective cohort study enrolled patients with newly diagnosed MM from three centers in China (Beijing Chao-Yang Hospital, Capital Medical University; the First Affiliated Hospital, Sun Yat-Sen University, and the Second Affiliated Hospital of Naval Medical University) from June 2008 to June 2018. A total of 401 newly diagnosed patients with MM who were candidates for ASCT were enrolled in this cohort, all received proteasome inhibitor and/or immunomodulator-based induction chemotherapy followed by ASCT. Baseline and follow-up data were collected. The patients were regrouped using R2-ISS. Progression-free survival (PFS) and overall survival (OS) were analyzed. The Kaplan-Meier method was used to analyze the survival curve and two survival curves were compared using the log-rank test. Cox regression analysis were performed to analyze the relationship between risk factors and survival.Results:The median age of the patients was 53 years (range 25-69 years) and 59.5% (240 cases) were men. Newly diagnosed patients with renal impairment accounted for 11.5% (46 cases). According to Revised-International Staging System (R-ISS), 74 patients (18.5 %) were diagnosed with stage Ⅰ, 259 patients (64.6%) with stage Ⅱ, and 68 patients (17.0%) with stage Ⅲ. According to the R2-ISS, the distribution of patients in each group was as follows: 50 patients (12.5%) in stage Ⅰ, 95 patients (23.7%) in stage Ⅱ, 206 patients (51.4%) in stage Ⅲ, and 50 patients (12.5%) in stage Ⅳ. The median follow-up time was 35.9 months (range, 6-119 months). According to the R2-ISS stage, the median PFS in each group was: 75.3 months for stage Ⅰ; 62.0 months for stage Ⅱ, 39.2 months for stage Ⅲ, and 30.3 months for stage Ⅳ; and the median OS was not reached, 86.6 months, 71.6 months, and 38.5 months, respectively. There were statistically significant differences in PFS and OS between different groups (both P<0.001). Multivariate Cox regression analysis showed that stages Ⅲ and Ⅳ of the R2-ISS were independent prognostic factors for PFS ( HR=2.37, 95% CI 1.30-4.30; HR=4.50, 95% CI 2.35-9.01) and OS ( HR=4.20, 95% CI 1.50-11.80; HR=9.53, 95% CI 3.21-28.29). Conclusions:The R2-ISS has significant predictive value for PFS and OS for transplant-eligible patients with MM in the new drug era. However, the universality of the R2-ISS still needs to be further verified in different populations.
ABSTRACT
ObjectiveTo investigate whether severe myelosuppression after chemotherapy is associated with prognosis in patients with breast cancer. MethodsTriple negative breast cancer (TNBC) patients who received chemotherapy at the Second Affiliated Hospital of Nanchang University from May 2, 2013 to May 2, 2018 were divided into a control group (no/mild myelosuppression) and a case group (severe myelosuppression). In this study, 251 patients with TNBC met the inclusion and exclusion criteria, including 125 patients in the control group (20 patients with grade 0 myelosuppression, 43 patients with grade I myelosuppression, 62 patients with grade Ⅱ myelosuppression), 126 patients in the case group (114 patients with grade Ⅲ myelosuppression, 12 patients with grade Ⅳ myelosuppression). The general clinicopathological data of the patients in the two groups, including age, pathological type of tumor, tumor T stage, tumor N stage, tumor Nottingham grade, intravascular cancer thrombus, were analyzed using the χ2 test. The disease-free survival (DFS) and overall survival (OS) of the two groups were analyzed using the Kaplan-Meier method. A Cox proportional hazards regression model with multiple factors was used to analyze the impact of post-chemotherapy severe myelosuppression on disease-free survival (DFS) and overall survival (OS) in patients with TNBC. ResultsThe differences in general clinicopathologic data between the two groups of patients were not statistically significant (all P>0.05). The 5-year disease-free survival (DFS) rate was significantly lower in the control group compared with the case group (75.2% vs. 85.7%, P=0.027). However, there was no statistically significant difference in the 5-year overall survival (OS) rate between the two groups (88.8% vs. 95.2%, P=0.057). The analysis of the multifactorial Cox proportional hazards regression model revealed that post-chemotherapy severe myelosuppression was an independent protective factor for disease-free survival (DFS) (HR=0.332, 95% CI: 0.173-0.638, P=0.001) and overall survival (OS) (HR=0.193, 95% CI: 0.062-0.602, P=0.005) in TNBC patients. ConclusionOur results show that TNBC patients with severe myelosuppression after chemotherapy have longer disease-free survival (DFS) than those with no/mild myelosuppression, and overall survival (OS) also tend to be prolonged compared with those with no/mild myelosuppression, and severe myelosuppression after chemotherapy can be used as an independent predictor of a good prognosis in breast cancer.
ABSTRACT
【Objective】 To construct a nomogram survival prediction model for patients with locally advanced renal cell carcinoma based on SEER database (n=7893), so as to provide reference for future prognosis study. 【Methods】 Case data were downloaded from the SEER database, and divided into the experimental group and validation group with a ratio of 7∶3 by simple randomization.The clinical information was analyzed, independent risk factors influencing prognosis were screened, and the overall survival (OS) and tumor-specific survival (CSS) were mapped.Model performance was evaluated using consistency index, area under the receiver operating characteristic curve (AUC), internal and external validation, and calibration curves. 【Results】 Patients’ age, tumor size, disease progression tpye, TNM stage, number of positive lymph nodes, marital status and pathological type were significantly correlated with OS and CSS (P<0.01).Based on the above predictors, the internal verification AUC of the 1-, 3- and 5- year OS nomogram model was 0.809, 0.721 and 0.715, respectively.The internal validation AUC of the nomogram model for 1-, 3- and 5- year CSS was 0.802, 0.745 and 0.735, respectively.The external validation AUC of the OS nomogram model was 0.792, 0.628 and 0.620 at 1, 3 and 5 years, respectively, and the external validation AUC of CSS was 0.943, 0.803 and 0.737 at 1.3 and 5 years, respectively, showing good model differentiation and accuracy. 【Conclusion】 The prediction performance of the nomogram model is good, and it can provide reference for individualized treatment.
ABSTRACT
【Objective】 To investigate the effects of radical prostatectomy (RP) or brachytherapy (BT) on the prognosis of patients with high-risk prostate cancer as initial treatment, in order to provide a reference for the selection of clinical treatment options. 【Methods】 The clinical data of 133 191 patients diagnosed with high-risk prostate cancer and treated with RP or BT during 2005 and 2014 were extracted from the SEER database.The 5-year and 10- year cancer-specific survival (CSS) and overall survival (OS) were compared with K-M analysis and univariate and multivariate Cox regression.The clinical data of another 253 patients diagnosed with high-risk prostate cancer in Subei People’s Hospital during 2015 and 2020 were collected, including 153 patients who received RP and 100 patients who received BT.The 5-year biochemical progress-free survival (bPFS) and CSS were compared with K-M analysis. 【Results】 Univariate analysis of SEER data showed that BT was associated with a higher risk of death (HR=1.319, 95%CI: 1.256-1.386, P<0.001); age, marital status and TNM stage were associated with higher risk of death (P<0.001).Multivariate analysis, adjusted for relevant variables, showed that BT did not result in a higher risk of death compared with RP (HR=0.964, 95%CI:0.924-0.996, P=0.808). The OS curve showed that the longer the observed survival time, the better OS of RP as compared to BT (P<0.001); however, the CSS survival curve showed that the longer the observed survival time, the better CSS of BT compared to RP (P<0.001).The single-center data analysis showed no significant difference between BT and RP in the 5-year bPFS (P=0.263) and CSS (P=0.946). 【Conclusion】 For patients with high-risk prostate cancer, there is a significant difference in the prognosis of the two treatments if there is no adjustment of age, marital status, TNM stage and other factors, and the efficacy of RP is better than that of BT, especially in patients with survival more than 10 years.However, there is no statistically significant difference in the prognosis after the possible confounding factors are adjusted.Therefore, the initial treatment choice for these patients should be weighed from multiple perspectives, and patients’ choices must be respected after they are fully informed.
ABSTRACT
【Objective】 To investigate the prognostic value of tumor location in patients with upper tract urothelial carcinoma (UTUC) treated with radical nephroureterectomy (RNU), and to develop and validate a nomogram model for predicting the overall survival (OS). 【Methods】 UTUC patients undergoing RUN at our hospital during Jan.2010 and Dec.2022 were retrospectively collected, 70% of whom were included in the training group and 30% in the validation group.According to the tumor location, patients were divided into renal pelvis tumor (RPT) group and ureteral tumor (UT) group.The differences in clinicopathological features and prognosis were analyzed.Based on multivariate Cox results, a nomogram model for predicting OS was developed and validated. 【Results】 A total of 366 patients (196 RPT and 170 UT) were included in this study.There were statistically significantly differences in urine cytology (P=0.001), hydronephrosis (P<0.001), history of bladder tumor (P=0.021), pathological T stage (P<0.001) and histological structure (P=0.037) between the two groups.Multivariate Cox results showed that patients with UT had a worse prognosis (HR=2.00, 95%CI: 1.22-3.27, P=0.006).Factors of the nomogram for predicting OS included age, tumor location, lymphovascular invasion and pathological T stage.The model showed good discrimination and calibration, and performed well in internal verification. 【Conclusion】 Compared with RPT, UT has a worse prognosis and the fat around the tumor should be surgically removed more thoroughly to avoid micro-residual.We successfully coustructed a nomogram model that can be used to predict the OS of UTUC patients after RNU surgery.
ABSTRACT
@#Introduction: This study aims to determine the prognostic factors and survival outcomes of patients that underwent this surgery. Method: A retrospective review of 43 patients who underwent exenteration for periocular malignancies over a 14-year period was carried out. Patient demographics, tumour histology, treatment details, surgical margins’ status and post-operative survival were recorded. The survival outcome examined was the overall survival (OS) rate. Cox regression and Kaplan-Meier analysis were used to evaluate post-exenteration survival. Results: In total, 20 females and 23 males with a median age of 62 ± 17.3 years were identified. The most common indication for exenteration was basal cell carcinoma (20.9%), followed by squamous cell carcinoma (18.6%), adenocystic carcinoma (14%), malignant melanoma (14%) and sebaceous gland carcinoma (11.6%). The independent predictors for worse OS on multivariate analysis were Chinese ethnicity (adjusted hazard ratio [aHR] 4.95, p =0.017), sebaceous gland carcinoma (aHR 57.61 p=0.006), adenocystic carcinoma (aHR 45.87, p=0.008), clear surgical margins (aHR 5.41, p=0.025), receiving only chemotherapy (aHR 169.13, p=0.004), and receiving both adjuvant chemotherapy and radiotherapy (aHR 41.51, p=0.010). Conclusion: We recommend targeted public health initiatives for Chinese patients due to their increased mortality risk from peri-ocular malignancies. In addition, we advise comprehensive adjuvant therapy for all patients regardless of whether a clear surgical margin is achieved. Basal cell carcinoma and adenocystic carcinoma may also benefit from genetic research. We advocate more training for ophthalmologists to identify periocular malignancies earlier for better treatment options and increased chances of survival.

Background and purpose:Follow-up data of 6 737 patients undergoing surgery for gastric cancer were collected based on hospital registration,and the 1-,3-and 5-years observed overall survival(OS)rates and disease-free survival(DFS)rates were analyzed to provide real-world research evidence for the prevention and control of gastric cancer and policy making in China.Methods:A total of 6 737 gastric cancer patients who underwent surgical treatment at Fudan University Shanghai Cancer center from 2015 to 2020 were included in this study.Clinical information and the follow-up endpoint data were collected through medical records review,telephone visits and death registry data linkage.The last follow-up date was November 30,2023.Kaplan-Meier method was applied in evaluating the 1-,3-and 5-year OS rate and DFS rate,and survival data were described by different subgroups including age group,gender,treatment period,tumor staging,and pathological characteristics.Results:With a median follow-up time of 50.99 months,the 5-year OS rate of surgically resected gastric cancer patients was 70.37%,and 5-year DFS rate in Ⅰ-Ⅲ stage cases was 69.46%.The 5-year OS rates of stage Ⅰ,Ⅱ,Ⅲ and Ⅳ were 94.32%,82.56%,51.01%and 23.97%,respectively.The differences in survival among patients with different age,tumor location,gross classification,Borrmann classification and Laurence classification were significant.Conclusion:Staging is an important factor directly affecting the survival of gastric cancer patients.Screening and early diagnosis and treatment in large population,especially high-risk group,should be strengthened to further improve the patients'survival.
ABSTRACT
Objective To explore the risk factors affecting the prognosis of patients with small bowel adenocarcinoma(SBA),construct the SBA survival risk model,and evaluate the clinical predictive value.Methods Clinical information and prognosis data of 2 639 patients included in the surveillance,epidemiology,and end results(SEER)database were retrospectively analyzed.Overall survival(OS)and disease specific survival(DSS)were used as prognostic indicators.The training group and validation group were randomized at a 7 ∶ 3 ratio using univariate and multivariate Cox regression analysis.Prognostic factors affecting SBA sur-vival were screened,and a prognostic prediction model was constructed.The receiver operation characteristic curve,model valida-tion by validation group,and clinical decision curve.Results Age(P<0.01),tumor site(P = 0.018),size(P = 0.042),T stage(P<0.01),detection rate of positive lymph nodes(P<0.01),single tumor focus(P<0.01),and secondary liver metastasis(P<0.01)were independent risk factors affecting prognosis of OS in patients with SBA;age(P<0.01),tumor size(P= 0.022),T stage(P<0.01),detec-tion rate of positive lymph nodes(P<0.01),single tumor focus(P<0.01),and secondary liver metastasis(P<0.01)were independent risk factors affecting the prognosis of DSS in patients with SBA.The nomogram,survival risk assessment model,and calibration prediction curve were consistent with the actual curve.Conclusion Age,tumor size,T stage,detection rate of positive lymph nodes,single tumor focus,and secondary liver metastasis were independent risk factors for OS and DSS in patients with SBA.Tumor site was also an inde-pendent risk factor for OS in SBA patients.The established prognostic prediction model has good predictive value,can effectively evaluate the prognosis of SBA patients,and can provide reasonable treatment advice for patients.
ABSTRACT
Objective To observe the efficacy and safety of VA regimen(venetoclax + azacitidine)in the treatment of patients with newly diagnosed unfit acute myeloid leukemia(AML).Methods From April 2021 to February 2023,55 unfit AML patients who were treated with VA regimen in the First Affiliated Hospital of Anhui Medical University were retrospectively analysed.The therapeutic efficacy and safety of VA regimen were evaluated.Results The median treatment courses of AML patients was 3(1-10),and complete response(CR)/CR with incomplete blood count recovery(CRi)rate was 78.2%and minimal residual(MRD)negative conversion rate was 61.8%after the first treatment course.CR/CRi rate and MRD negative conversion rate increased gradually with the increase of treatment course.Patients with IDH1/IDH2,NPM1,ASXL1 mutations and without TP53 mutations responded well to the VA regimen.The median follow-up time was 9.1(1.2-24.0)months.39 patients survived and 16 patients died.The median overall survival(OS)was 17.4 months.Patients with CR/CRi had significantly longer OS duration than patients with partial response or non-response(P<0.001).Almost all patients had different degrees of anemia,thrombocytopenia,leukopenia.In terms of non-hematological adverse events,infection was the most common.Conclusion The VA regimen achieved a higher treatment response rate in newly diagnosed unfit AML patients,and partial response patients could quickly obtain negative MRD.IDH1/IDH2,ASXL1,NPM1,TP53 mutations may be the predictors of patient outcomes.
ABSTRACT
ABSTRACT Currently, the incidence of esophageal cancer continues to rise around the world. Because of its good early prognosis, it is of great significance to establish an effective model for predicting the survival of EC patients. The purpose of this study was to predict survival after diagnosis in Esophageal Cancer (EC) patients by constructing a valid clinical nomogram. In this study, 5037 EC patient samples diagnosed from 2010 to 2015 were screened by accessing the SEER database, and 8 independent prognostic factors were screened by various methods, and Cox multivariate regression was included to construct a prognostic model and nomogram for esophageal cancer. to estimate esophageal cancer recurrence and overall survival. Calibration of the nomogram predicted probabilities of 1-year, 3-year and 5-year survival probability, which were closely related to actual survival. In conclusion, this study validated that the column-line graphical model can be considered an individualized quantitative tool for predicting the prognosis of patients with EC in order to assist clinicians in making therapeutic decisions.

Background: Aim of this study was to evaluate the clinico-epidemiological profile and treatment outcome of pituitary adenomas. Methods: This was a retrospective study performed in the department of Radiation Oncology, Sher-I-Kashmir Institute of Medical Sciences, Soura, Srinagar, India, in which 30 cases diagnosed with pituitary adenoma from January 2016 to December 2021 were studied. There clinical and epidemiological features, treatment, overall survival and follow-up data was analyzed. Results: Most patients were female in gender 17 (57%), and the incidence rate was higher in female patients than male. Microadenoma was seen in just 4 (13%) patients. Macroadenoma in 12 (40%) and giant tumours in 14 (47%). At three and five years, the overall survival rate was 92% and 83%, respectively. Additionally, patients who got adjuvant radiation had a higher overall survival rate (84% versus 76%, p=.833) than those who did not. Conclusions: Radiotherapy is an effective treatment for pituitary adenomas, able to achieve excellent disease control. Patients with pituitary adenomas should be identified at an early stage so that effective treatment can be implemented. Initial therapy is generally transsphenoidal surgery with irradiation reserved for patients who do not achieve adequate reduction in tumor size after surgery.
