Prognostic impact of the ratio of preoperative CA19-9 to liver enzyme levels in pancreatic cancer patients with jaundice (predictability of combined CA19-9/AST and CA19-9/γ-GGT for jaundiced PDAC patients)

BackgroundCarbohydrate antigen 19–9 (CA19-9) has been reported as the most significant survival predictor of patients with pancreatic ductal adenocarcinoma (PDAC). However, the elevation of CA19-9 could interfere with obstructive jaundice and the predictive value of CA19-9 in PDAC patients with jaundice remains to be analyzed and elucidated to find possible adjustments.ObjectiveTo evaluate the predictability of preoperative CA19-9 and its adjustments for the overall survival (OS) of PDAC patients by analyzing the relationship between preoperative serum CA19-9 and total bilirubin (TBIL).MethodsA total of 563 consecutive patients who underwent surgery for primary pancreatic adenocarcinoma in our center between January 2015 and September 2018 were retrospectively reviewed. Clinicopathologic information was collected and preoperative parameters such as CA19-9, CEA, TBIL, γ-GGT, AST, ALT, and ALP were recorded as well as overall survival rates, which began from the date of operation to that of death or the last follow-up. Kaplan-Meier survival curves with log-rank test and Cox regression models were applied using SPSS and the survival and survminer packages in R software.ResultsUsing 39/390/1000 as the cut-off values for preoperative serum CA19-9, significant capability of OS stratification was found in the total cohort (p < 0.001, MST = 29.7/19.1/15.2/12.1 months) and patients with TBIL <102.6 μmol/L (p < 0.001, MST = 32.2/19.6/15.0/11.2 months). However, in the subgroup of TBIL≥102.6 μmol/L, this classification method was replaced by the combined scoring of CA19-9/AST and CA19-9/γ-GGT.ConclusionsAs an independent predictor of overall survival of PDAC patients, preoperative serum CA19-9 is defective in survival stratification when TBIL≥102.6 μmol/L but a positive survival prognosis could be achieved with the application of combined preoperative CA19-9/AST and CA19-9/γ-GGT.     

Clinical significance and predictors of complete or near-complete histological response to preoperative chemoradiotherapy in patients with localized pancreatic ductal adenocarcinoma

BackgroundThe clinical value and predictors of a favorable histological response to preoperative chemoradiotherapy (CRT) in pancreatic ductal adenocarcinoma (PDAC) remains undefined.ObjectiveTo assess the significance and predictors of a favorable histological response to preoperative CRT in patients with localized PDAC.MethodsThe study included 203 patients with localized PDAC undergoing curative-intent resection after CRT. The rate of R0 resection and overall survival (OS) and recurrence-free survival (RFS) were correlated with the grading of histological response to determine optimal stratification. Clinical factors associated with a significant histological response were evaluated using multivariate regression analysis.ResultsAmong all patients, eight patients (3.9%) had a grade 4 (pCR); 40 (19.4%) had a grade 3 estimated rate of residual neoplastic cells <10% (near-pCR); and 155 (76.7%) had a grade 1/2 limited response. The 48 patients with pCR/near-pCR achieved significantly higher R0 resection rate (100%) than those with grade 1/2 (80.0%). The 5-year OS and RFS rates were significantly higher in the patients with pCR/near-pCR (45.3% and 36.5%) than in those with grade 1/2 (27.1% and 18.5%). Gemcitabine plus S-1 based CRT, serum CA19-9 level after CRT <83 U/mL, and interval from initial treatment to surgery ≥4.4 months were independent predictive factors for pCR/near-pCR.ConclusionspCR or near-pCR to preoperative CRT contributed to achieving a high rate of R0 resection and improving survival for localized PDAC. The use of gemcitabine plus S-1 as a radiosensitizer, lower serum CA19-9 level after CRT, and longer preoperative treatment duration were significantly associated with pCR or near-pCR.     

Prognostic significance of preoperative PNI and CA19-9 for pancreatic ductal adenocarcinoma: A multi-institutional retrospective study

BackgroundThe aim of this study was to investigate the clinical value of nutritional and immunological prognostic scores as predictors of outcomes and to identify the most promising scoring system for patients with pancreatic ductal adenocarcinoma (PDAC) in a multi-institutional study.MethodsData were retrospectively collected for 589 patients who underwent surgical resection for PDAC. Prognostic analyses were performed for overall (OS) and recurrence-free survival (RFS) using tumor and patient-related factors, namely neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, Prognostic Nutritional Index (PNI), Glasgow Prognostic Score (GPS), modified GPS, C-reactive protein-to-albumin ratio, Controlling Nutritional Status score, and the Geriatric Nutritional Risk Index.ResultsCompared with PDAC patients with high PNI values (≥46), low PNI (<46) patients showed significantly worse overall survival (OS) (multivariate hazard ratio (HR), 1.432; 95% CI, 1.069–1.918; p = 0.0161) and RFS (multivariate HR, 1.339; 95% CI, 1.032–1.736; p = 0.0277). High carbohydrate antigen 19–9 (CA19-9) values (≥450) were significantly correlated with shorter OS (multivariate HR, 1.520; 95% CI, 1.261–2.080; p = 0.0002) and RFS (multivariate HR, 1.533; 95% CI, 1.199–1.961; p = 0.0007). Stratification according to PNI and CA19-9 was also significantly associated with OS and RFS (log rank, P < 0.0001).ConclusionsOur large cohort study showed that PNI and CA19-9 were associated with poor clinical outcomes in PDAC patients following surgical resection. Additionally, combining PNI with CA19-9 enabled further classification of patients according to their clinical outcomes.

Post-adjuvant chemotherapy CA19-9 levels predict prognosis in patients with pancreatic ductal adenocarcinoma: A retrospective cohort study

BackgroundCarbohydrate antigen 19-9 (CA19-9) is a widely used tumor marker for pancreatic ductal adenocarcinoma (PDAC). In addition, several studies have reported the utility of both pre- and postoperative CA19-9 levels as prognostic factors in resectable PDAC. However, little is known about the implications of post-adjuvant chemotherapy (AC) CA19-9 levels. The purpose of this study was to examine the utility of the post-AC CA19-9 level as a prognostic marker for relapse-free survival (RFS) in resectable PDAC.MethodsA total of 119 patients who completed AC were analyzed (normal post-AC CA19-9, n = 79; high post-AC CA19-9, n = 40). The upper limit of the normal (ULN) serum level of CA19-9 was 37 U/mL.ResultsMedian RFS was significantly shorter for patients with high post-AC CA19-9 levels than for those with normal post-AC CA19-9 (10.4 months vs. 29.6 months, respectively; p < 0.001). After adjustment, high post-AC CA19-9 level was an independent predictive factor for short RFS (hazard ratio for RFS, 2.72). Median overall survival was significantly shorter in patients with high post-AC CA19-9 levels than in those with normal postoperative CA19-9 levels (24.7 months vs. 92.1 months, respectively; p < 0.001). The optimal cutoff value of post-AC CA19-9 levels for prediction of early recurrence was >1.5 × UNL (55.5 U/mL), with a 74.2% positive predictive value.ConclusionsThe present results show that high post-AC CA19-9 level is an independent prognostic factor for short RFS in patients with resected PDAC. In addition, it may be useful for predicting early recurrence.     

Diagnostic role and prognostic value of tumor markers in high-grade gastro-enteropancreatic neuroendocrine neoplasms

ObjectivesHigh-grade gastro-enteropancreatic neuroendocrine neoplasms (GEP-NENs) are a heterogeneous group of rare tumors of two different types: well differentiated neuroendocrine tumors grade 3 (NETs G3) and poorly differentiated neuroendocrine carcinomas (NECs). This study aimed to explore the value of eight common preoperative markers in differentiating NETs G3 from NECs and the prognosis prediction of high-grade GEP-NENs.MethodsSeventy-two patients diagnosed with high-grade GEP-NENs who underwent surgery at our institution were recruited for this study. Demographic and clinicopathological characteristics, preoperative serum tumor markers, and survival data were collected and analyzed. Kaplan–Meier methods were used to analyze survival rates, and a Cox regression model was used to perform multivariate analyses.ResultsSerum carcinoembryonic antigen (CEA) was dramatically higher in NECs than in NETs G3 (P = 0.025). After follow-up, 57 of the 72 patients remained for survival analysis. Elevated serum carbohydrate antigen 19-9 (CA19-9), CEA, cancer antigen 125 and sialic acid (SA) levels indicated poorer survival of high-grade GEP-NEN patients. Only CA19-9 (HR: 6.901, 95% CI: 1.843 to 25.837, P = 0.004) was regarded as an independent risk factor for overall survival. Serum CA19-9 (HR: 4.689, 95% CI: 1.127 to 19.506, P = 0.034) was also regarded as an independent factor for overall survival in NECs.ConclusionsSerum CEA levels can be used to distinguish NETs G3 from NECs. Preoperative CA19-9, CEA, cancer antigen 125 and SA levels have predictive value in the prognosis of high-grade GEP-NENs. Preoperative CA19-9, neuron-specific enolase, and SA levels can predict the prognosis of NECs.

目的探讨血清CEA、CA19-9、CA125结合临床病理对术前判断是否具有结直肠癌腹膜转移的意义。 方法选取2014年1月至2017年10月在哈尔滨医科大学附属第二临床医学院行手术治疗的结肠癌及肿瘤位于直肠腹膜反折以上的直肠癌患者,共1 215例。其中,无腹膜转移的患者988例,同时性腹膜转移的患者227例,比较两组临床资料。 结果高分化腺癌、中分化腺癌、低分化腺癌、黏液腺癌、印戒细胞癌发生腹膜转移的几率分别为0、5.4%、35.6%、45.3%、75%,病理恶性程度越高越容易出现腹膜转移。血清CEA、CA19-9及CA125三者对结直肠癌腹膜转移的辅助诊断中,以CA125最为敏感,敏感度为100%,曲线下面积为0.897,CA125的这两项明显高于CEA及CA19-9,其特异度与CEA接近,较CA19-9低。CA19-9的特异度最高,为86%,但其灵敏度（47%）、曲线下面积（0.669）为三者中最低。CEA、CA19-9、CA125增高越明显,发生腹膜转移的几率就越大,当CEA＋CA125增高或CA125＋CA19-9增高或CEA＋CA125＋CA19-9增高时,发生腹膜转移的几率分别为65.7%、73.1%、77.3%。 结论通过CEA、CA19-9、CA125结合临床病理等检查的辅助,可以提高术前诊断结直肠癌腹膜转移的准确率,有助于术前判断患者的病情及预后。     

CA19-9、CA125和碱性磷酸酶对胆囊癌临床分期的意义

背景：近年原发性胆囊癌的发病率明显上升,提高胆囊癌的早期诊断是改善治疗和预后、提高生存率和生活质量的关键。目的：探讨检测CA19-9、CA125和碱性磷酸酶（AKP）对胆囊癌的临床分期以及术前评估的意义。方法：收集2003年1月~2010年5月华中科技大学同济医学院附属协和医院经病理检查确诊为原发性胆囊癌的159例患者,对不同TNM分期胆囊癌患者的血清CA19-9、CA125和AKP进行比较分析。结果：Ⅰ＋Ⅱ＋ⅢA期、ⅢB期、Ⅳ期胆囊癌患者血清CA19-9、CA125和AKP水平相比差异有统计学意义（P〈0.01）;Ⅰ＋Ⅱ＋ⅢA期血清CA19-9阳性率和AKP异常率显著低于ⅢB期、Ⅳ期（P〈0.01）,而血清CA125阳性率显著低于Ⅳ期（P〈0.01）。Ⅰ＋Ⅱ＋ⅢA期血清CA19-9水平和阳性率以及AKP水平和异常率均显著低于ⅢB＋Ⅳ期（P〈0.01）,而血清CA125水平和阳性率均无明显差异。联合检测的阳性率明显高于单个指标的阳性率（P〈0.01）。结论：CA19-9、CA125、AKP可作为胆囊癌的辅助诊断手段,对胆囊癌的临床分期和术前评估具有较好的临床价值。联合检测可提高诊断效率。     

Prognostic relevance of preoperative bilirubin-adjusted serum carbohydrate antigen 19-9 in a multicenter subset analysis of 179 patients with distal cholangiocarcinoma

BackgroundDistal cholangiocarcinoma (DCC) is a rare malignancy and validated prognostic markers remain scarce. We aimed to evaluate the role of serum CA19-9 as a potential biomarker in DCC.MethodsPatients operated for DCC at 6 high-volume surgical centers from 1994 to 2015 were identified from prospectively maintained databases. Patient baseline characteristics, surgical and histopathological parameters, as well as overall survival after resection were assessed for correlation with preoperative bilirubin-adjusted serum carbohydrate antigen 19-9 (CA19-9). Preoperative CA19-9 to bilirubin ratio (CA19-9/BR) was classified as elevated (≥ 25 U/ml/mg/dl) according to the upper serum normal values of CA19-9 (37 U/ml) and bilirubin (1.5 mg/dl) giving a cut-off at ≥ 25 U/ml/mg/dl.ResultsIn total 179 patients underwent resection for DCC during the study period. High preoperative CA19-9/BR was associated with advanced age and regional lymph node metastases. Median overall survival after resection was 27 months. Elevated preoperative serum CA19-9/bilirubin ratio (HR 1.6, p = 0.025), T3/4 stage (HR 1.8, p = 0.022), distant metastasis (HR 2.5, p = 0.007), tumor grade (HR 1.9, p = 0.001) and R status (HR 1.7, p = 0.023) were identified as independent negative prognostic factors following multivariable analysis.ConclusionElevated preoperative bilirubin-adjusted serum CA19-9 correlates with regional lymph node metastases and constitutes a negative independent prognostic factor after resection of DCC.     

Prognostic value of CA 19-9, CEA, CRP, LDH and bilirubin levels in locally advanced and metastatic pancreatic cancer: results from a multicenter, pooled analysis of patients receiving palliative chemotherapy

Purpose

CA 19-9 is the only established tumor marker in pancreatic cancer (PC); the prognostic role of other serum markers like CEA, CRP, LDH or bilirubin has not yet been defined.

Methods

We pooled pre-treatment data on CA 19-9, CEA, CRP, LDH and bilirubin levels from two German multicenter randomized phase II trials together with prospective patient data from one high-volume German Cancer Center. Marker levels were assessed locally before the start of palliative first-line therapy for advanced PC and serially during treatment (for CA 19-9 only). Clinical and biomarker data (overall 12 variables) were correlated with the efficacy endpoints time-to-progression (TTP) and overall survival (OS) by using uni- and multivariate Cox models.

Results

Data from 291 patients were included in this pooled analysis; 253 patients (87 %) received treatment within prospective clinical trials. Median TTP in the study cohort was 5.1 months and median OS 9.0 months. In univariate analysis, pre-treatment CA 19-9 (HR 1.55), LDH (HR 2.04) and CEA (HR 1.89) levels were significantly associated with TTP. Regarding OS, baseline CA 19-9 (HR 1.46), LDH (HR 2.07), CRP (HR 1.69) and bilirubin (HR 1.62) were significant prognostic factors. Within multivariate analyses, pre-treatment log [CA 19-9] (as continuous variable for TTP) and log [bilirubin] as well as log [CRP] (for OS) had an independent prognostic value. A CA 19-9 decline of ≥25 % during the first two chemotherapy cycles was predictive for TTP and OS, independent of the applied CA 19-9 assay.

Conclusion

Baseline CA 19-9 and CA 19-9 kinetics during first-line chemotherapy are prognostic in advanced PC. Besides that finding other serum markers like CRP, LDH and bilirubin can also provide prognostic information on TTP and OS.     

High level of preoperative carbohydrate antigen 19-9 is a poor survival predictor in gastric cancer

AIM:To assess the clinical significance and the prognostic value of preoperative serum carbohydrate antigen 19-9(CA 19-9)level in gastric cancer.METHODS:Between January 2005 and December2006,1960 patients underwent surgery for histologically confirmed gastric cancer.Of these,163 patients had elevated serum levels of CA 19-9 preoperatively,and1628 patients had normal serum levels of CA 19-9 preoperatively.For this study,325 patients were selected from the group of 1628 patients by age,sex,and cancer stage to serve as controls.Statistically significant differences in survival rates were calculated using the log-rank test.A P value less than 0.05 was considered statistically significant and was determined using SAS software.RESULTS:The baseline characteristics showed some differences between the two groups with regard to histology.Overall survival(OS)in the elevated and nonelevated group was 37.90 and 68.67 mo,respectively(P<0.001).N stage(P=0.001)was a significant predictor of disease-free survival by multivariate analysis.Also,N stage(P<0.001),and the presence of peritoneal metastasis(P<0.001)remained independent factors in predicting OS by multivariate analysis.Additionally,preoperative serum CA 19-9 levels were significantly associated with OS in univariate(P=0.009)and multivariate(P=0.021)analyses.CONCLUSION:Serum CA 19-9 can be considered an independent prognostic factor in predicting OS in patients anticipating surgery for gastric cancer.     

The high stromal SPARC expression is independently associated with poor survival of patients with resected pancreatic ductal adenocarcinoma treated with adjuvant gemcitabine in combination with S-1 or adjuvant gemcitabine alone

Background

Although postoperative adjuvant chemotherapy for pancreatic ductal adenocarcinoma (PDAC) improves survival, its efficacy varies among individuals. Identification of biomarkers that can predict the efficacy of adjuvant chemotherapy for PDAC is essential.

结直肠癌患者根治术前血清CEA和CA19-9表达水平对预后的预测价值

目的探讨结直肠癌患者根治术前CEA、CA19-9水平对预后的预测价值。 方法回顾性分析复旦大学附属肿瘤医院2003年12月至2007年1月间491例接受根治性切除的Ⅱ、Ⅲ期结直肠癌患者临床资料,包括患者术前血清CEA和CA19-9水平、临床病理资料及预后情况。利用单变量和多变量分析患者年龄、性别、肿瘤部位、肿瘤分化、TNM分期、肿瘤侵犯深度及淋巴结转移个数与预后的关系。 结果患者术前血清CEA和CA19-9水平、TNM分期、淋巴结转移数、肿瘤侵犯深度、肿瘤的分化都与预后相关。在多变量分析中,CEA和CA19-9水平、TNM分期、肿瘤分化是总生存的独立预测因素,CA19-9水平、TNM分期、肿瘤分化是无病生存的独立预测因素。 结论术前血清CA19-9与CEA水平均对结直肠癌患者的预后有预测价值。CA19-9水平应该作为常规的术前检查指标,对CEA检测结果有补充作用。     

Prognostic significance of serum CA19-9 levels in resected pancreatic cancer

Twenty-eight patients with histologically proven pancreatic adenocarcinoma were investigated to evaluate the utility of serum CA19-9 levels as a prognostic indicator after pancreatic resection. Three patients were excluded from the study because their serum CA19-9 levels remained normal throughout the course of the disease. Of the remaining 25 patients, those with preoperative serum CA19-9 levels ≤200U/ml had a better prognosis than those with serum CA19-9 levels >200 U/ml; however, the difference between the two groups was not significant (P=0.13). Serum CA19-9 levels 30 days after pancreatic resection were normalized (≤37 U/ml) in 11 patients (group A), and the survival rate of this group was significantly higher than that of the group of patients with persistently elevated CA19-9 levels (>37 U/ml) (group B) (P<0.005). Other factors i.e., preoperative CA19-9 values, tumor size, lymph node metastasis, histology, and stage classification showed no significant differences between group A and group B. Univariate analysis of the findings for the 25 patients showed that the stage classification and postoperative CA19-9 levels were of prognostic significance for prolonged survival. Other factors, i.e., gender, age, histology, preoperative CA19-9 levels, location of the tumor, and mode of operation, had no significance as prognostic indicators. Multivariate analysis showed that postoperative CA19-9 level was the only significant independent predictor of poor survival. Postoperative serum CA19-9 level appears to be useful as a prognostic indicator after resection of pancreatic cancer.     

Preoperative CA 125 is significant indicator of curative resection in gastric cancer patients

AIM: To investigate the correlation among tumor markers, curative resection, and recurrence in gastric cancer.METHODS: The patients with preoperative tumormakers [Carcinoembryonic antigen, Carbohydrate antigen(CA) 19-9, and CA 125] and elective gastrectomy between January 2000 and December 2009 at Chungbuk National University Hospital were enrolled in this study. We analyzed the relationship among the tumor makers, curative resection and recurrence, retrospectively.RESULTS: Among the 679 patients with gastric cancer, curative resection was 93.6%(n = 636) and noncurative resection was 6.4%(n = 43). The independent risk factors for the non-curative resection were tumor location and the positivity of preoperative serum CA 19-9 and CA 125 levels. After curative resection, the independent prognostic risk factors for recurrence in curative resection were gender, stage, and preoperative increased serum CA 125 level(HR = 2.431, P =0.020), in a multivariate analysis. CONCLUSION: Preoperative CA 125 is a useful predictive biomarker for curative resection and prognostic biomarker for recurrence in gastric cancer patients.     

Nomogram and competing risk model to predict recurrence after curative surgical resection of PDAC

BackgroundSurgical resection remains the only potentially curative treatment for pancreatic ductal adenocarcinoma (PDAC). However, a number of patients get disease recurred in a short time post-operation. Few studies have focused on the predictors of different recurrence patterns of PDAC.ObjectiveTo try to establish and verify a nomogram to predict recurrence free survival (RFS) in PDAC patients, and to distinguish the risk factors of local recurrence first and distant metastasis first via competing risk model.MethodsPatients who underwent radical pancreatectomy for PDAC in our center from 2010 to 2018 were reviewed retrospectively. Kaplan-Meier methods and multivariate Cox regression analyses were used to identify the clinicopathological predictors of recurrence post-operation. And then, a nomogram was constructed and validated. Competing risk regression model was used to compare the predictors between local recurrence group and distant metastasis group.ResultsA total of 200 patients were included into the final analysis, and 153 patients got disease relapsed post-operation. CA19-9 level, vascular resection, tumor differentiation, lymph node ratio (LNR) and adjuvant chemotherapy were identified as independent risk factors for recurrence free survival (RFS) and incorporated into the nomogram. The C-index of the nomogram was 0.650. Competing risk model indicated that the status of lymph-node metastasis was significantly associated the patterns of first relapse.ConclusionsNomogram and competing risk model were constructed to quantify the risk of recurrence following surgery for PDAC. Our findings may be useful for predicting RFS and recurrence pattern in clinical work.     

Combination of preoperative CA19-9 levels,cell differentiation,and age predicts survival for patients with gastric cancer before surgery

Gastric cancer (GC) is very common in China, posing a threat to public health, with high morbidity and mortality ranks. Tumor-node-metastasis (TNM) staging system is routinely used to predict prognosis for patients with GC but only available after surgery. Therefore, searching for markers that can predict prognosis of GC patients before surgery is desirable to assist management decisions preoperatively. Among 322 GC patients followed-up for 128 months, the tumor markers alpha fetoprotein, carcinoembryonic antigen, carbohydrate antigen 19-9 (CA19-9), carbohydrate antigen 15-3 and carbohydrate antigen 72-4 of 168 patients were detected before surgery, and their impact on survival was analyzed. Four major findings were revealed: (1) Preoperative examined CA19-9 levels and cell differentiation using endoscopic biopsies were positively correlated with lymphatic metastases and TNM stages obtained after surgery. (2) Kaplan-Meier analyses demonstrated that poor survival of patients with GC was associated with higher CA19-9 levels, poor cell differentiation, and older age. (3) Cox multi-factorial regression analyses indicated that, in terms of predicting overall survival for GC patients, preoperative CA19-9 level, cell differentiation and age were independent factors, respectively, comparable to postoperative TNM staging system. (4) Using receiver operating characteristic curve analysis, we first revealed that preoperative CA19-9 levels and cell differentiation had the impact weights (IW) on survival comparable to postoperative TNM components. These findings suggest that preoperative CA19-9 levels, cell differentiation and age are useful prognostic related markers for GC patients, superior to postoperative TNM system in terms of timing for management. We propose that, assisted by clinical imaging, a comprehensive utilization of these preoperative survival-predictors may help formulate individualized medical management for GC patients such as surgical strategy, optimal chemotherapy and radiotherapy, and appropriate follow-up intervals after surgery.

??Abstract??Objective To investigate the roles of tumor markers in diagnosis and prognosis assessment of patients with pancreatic carcinoma.Methods We collected 198 cases of pancreatic carcinoma??50 cases of benign pancreatic diseases and 61 cases of normal controls.Radioimmunoassay was used to detect the tumor markers such as CA19-9??CA242??CA125??CA50 and CEA.A total of 120 cases of pancreatic carcinoma were followed up and the factors influencing their prognosis were analyzed.Results The average levels of CA19-9??CA242 and CA125 in pancreatic carcinoma cases were significantly higher than those in the controls and benign pancreatic disease cases (P<0.05).We obtained sensitivities of 80.84%??72.50%??56.67%??56.12% and 45.31% for CA19-9??CA242??CA125??CA50 and CEA??respectively??and specificities of 76.80%??69.32%??72.96 %??65.33% and 57.40% for CA19-9??CA242??CA125??CA50 and CEA??respectively.Combined detection increased the sensitivity but reduced the specificity.The median survival time of the pancreatic cancer patients was 5.5 months.Patients with tumors located at pancreatic body??tail and the whole pancreas had less survival time than those with tumors located at pancreatic head and neck.Patients with higher levels of CA19-9??CA242 and CA125 had less survival time (P<0.05).Cox multivariate proportional hazards model showed that CA19-9 and CA242 were independent prognostic factors (P<0.05).Conclusion Early diagnosis of pancreatic carcinoma depends on serum examinations of tumor marker.Combined detection increases the sensitivity and reduces the specificity of the markers.Patients with tumor located at the pancreatic body??pancreatic tail??and with higher levels of CA19-9??CA242 and CA125 may have less survival time.CA19-9 and CA242 are independent prognostic factors that may help to assess the prognosis of pancreatic carcinoma.     

Modified Child-Pugh grade vs albumin-bilirubin grade for predicting prognosis of hepatocellular carcinoma patients after hepatectomy

BACKGROUND Hepatectomy is the main treatment for patients with hepatocellular carcinoma(HCC)and it has a high possibility for long-term cure potential.But the postoperative mortality and recurrence rates remain high.Since the long-term prognosis of HCC patients is strongly linked to liver function,preoperative assessment of liver function is very important for HCC patients.AIM To compare the predictive power of the modified Child-Pugh(MCP)and albumin-bilirubin(ALBI)grades for the long-term outcome of HCC.METHODS From January 2010 to June 2017,a total of 204 patients with HCC who underwent surgery at the Second Affiliated Hospital of Chongqing Medical University were enrolled in this retrospective study.Multivariate Cox regression analysis was used to determine the independent predictive factors of survival and relapse.The area under the curve(AUC)was used to evaluate the discriminative performance of the MCP grade and ALBI grade to predict the postoperative overall survival(OS)time and recurrence-free survival(RFS)time.RESULTS The median OS and RFS times were 44.0 mo(range:22.0-74.0 mo)and 22.0 mo(range:5.0-45.0 mo),respectively.The median OS and RFS times of MCP grades 1,2,and 3 patients were 60.0,39.0,and 18.0 mo(P<0.001)and 36.0,15.0,and 7.0 mo(P<0.001),respectively.The median OS and RFS times of ALBI grades 1,2,and 3 patients were 56.0,26.0,and 6.0 mo(P<0.001)and 25.0,10.0,and 3.0 mo(P=0.003),respectively.Both the MCP and ALBI grades were more accurate than the Child-Pugh grade for predicting long-term prognosis.Further analysis demonstrated that for both predicting OS and RFS,the MCP grade performed better than the ALBI grade(AUC:0.642 vs 0.605 for OS;0.659 vs 0.594 for RFS).CONCLUSION The MCP grade is more accurate than the ALBI grade for predicting long-term outcome of patients with HCC.     

Clinical significance of serum carbohydrate antigen 19.9 and duke pancreatic monoclonal antigen type 2 for the prediction of hematogenous metastases in patients with pancreatic ducal adenocarcinoma

ObjectivesThe aim of the present study was to investigate the effectiveness of serum carbohydrate antigen (CA) 19.9 and duke pancreatic monoclonal antigen type 2 (DUPAN-2) levels in the prediction of early hematogenous metastases and as indicators of neoadjuvant therapy in patients with pancreatic ductal adenocarcinoma (PDAC).MethodsOf the 293 enrolled PDAC patients, 61 had hematogenous metastases at the initial evaluation. One hundred and twenty patients without metastases underwent surgical resection. Of the 120 patients who underwent surgical resection, 45 underwent preoperative treatment and 29 developed early hematogenous metastases within 1 year after the surgery. In patients who underwent preoperative therapy, serum CA 19.9 and DUPAN-2 levels were measured within 2 weeks before the preoperative therapy and the subsequent surgery.ResultsThe elevated serum CA 19.9 and DUPAN-2 levels were significantly associated with hematogenous metastasis at initial evaluation and early hematogenous metastasis after surgery. The rate of early hematogenous metastasis and overall survival (OS) in patients with high CA 19.9 and/or high DUPAN-2 (CA 19.9 > 200 U/mL and/or DUPAN-2 >300 U/mL) were 46.3% and 18 months, respectively, whereas the metastatic rate and OS in patients with low CA 19.9 and DUPAN-2 were 12.7% and 37.5 months, respectively. Furthermore, in patients with high CA 19.9 and/or high DUPAN-2, preoperative therapy significantly reduced the rate of early hematogenous metastasis and prolonged the OS.ConclusionsSerum CA 19.9 and DUPAN-2 levels are useful predictors of early hematogenous metastasis and indicators for effectiveness of neoadjuvant therapy in PDAC patients.
