Long-term Prognostic Factors Of Patients Research Articles

Prognostic nutritional index is a prognostic factor for patients with gastric cancer and esophagogastric junction cancer undergoing proximal gastrectomy with esophagogastrostomy by the double-flap technique: A secondary analysis of the rD-FLAP study

PurposeAlthough proximal gastrectomy (PG) is commonly used in patients with upper gastric cancer (GC) and esophagogastric junction (EGJ) cancer, long-term prognostic factors in these patients are poorly understood. The double-flap technique (DFT) is an esophagogastrostomy with anti-reflux mechanism after PG; we previously conducted a multicenter retrospective study (rD-FLAP) to evaluate the short-term outcomes of DFT reconstruction. Here, we evaluated the long-term prognostic factors in patients with upper GC and EGJ cancer. MethodsThe study was conducted as a secondary analysis of the rD-FLAP Study, which enrolled patients who underwent PG with DFT reconstruction, irrespective of disease type, between January 1996 and December 2015. ResultsA total of 509 GC and EGJ cancer patients were enrolled. Univariate and multivariate analyses of overall survival demonstrated that a preoperative prognostic nutritional index (PNI) < 45 (p < 0.001, hazard ratio [HR]: 3.59, 95% confidential interval [CI]: 1.93–6.67) was an independent poor prognostic factor alongside pathological T factor ([pT] ≥2) (p = 0.010, HR: 2.29, 95% CI: 1.22–4.30) and pathological N factor ([pN] ≥1) (p = 0.001, HR: 3.27, 95% CI: 1.66–6.46). In patients with preoperative PNI ≥45, PNI change (<90%) at 1-year follow-up (p = 0.019, HR: 2.54, 95%CI: 1.16–5.54) was an independent poor prognostic factor, for which operation time (≥300 min) and blood loss (≥200 mL) were independent risk factors. No independent prognostic factors were identified in patients with preoperative PNI <45. ConclusionsPNI is a prognostic factor in upper GC and EGJ cancer patients. Preoperative nutritional enhancement and postoperative nutritional maintenance are important for prognostic improvement in these patients.

Implication of ERBB2 as a Predictive Tool for Survival in Patients with Pancreatic Cancer in Histological Studies.

Pancreatic cancer will be positioned by the year 2030 as the second cause of oncological death after lung cancer. The pathophysiology of the most common variety, which involves the adenocarcinoma of the pancreas, represents one of the main challenges for current oncology to explain its tumorigenesis and create a targeted treatment. The tumor microenvironment, metastatic capacity, and lack of early diagnosis lead patients to present advanced stages at the time of diagnosis. Despite numerous efforts, little progress has been made in clinical outcomes and with respect to the improved survival of these patients. For this reason, in recent years, numerous diagnostic tests, treatments, and possible approaches in the fields of radiotherapy, chemotherapy, immunotherapy, and surgery have been developed to find a combination of methods that improves life expectancy in patients diagnosed with this disease. On the other hand, the scientific community has made numerous advances in the molecular bases of pancreatic cancer since several oncogenetic pathways have been described and the markers expressed by the tumor have proven to be useful in the prognosis of pancreatic adenocarcinoma. These molecular alterations allow the study of possible therapeutic targets that improve the prognosis of these patients, but even numerous tumor cell-individual interactions must be explained to understand the underlying pathophysiology causing the high mortality. Therefore, the purpose of our study is to examine the expression of markers such as EGFR, Cyclin D1, andCDK4 in order to find a relationship with the possible long-term prognostic factors of patients affected by pancreatic ductal adenocarcinoma. Our results show that there is a prognostic role for ErbB2, EGFR, beta catenin, cyclin D1, and CDK4. Of these, we highlight the clinical importance of ErbB2 in the survival rates of patients who overexpress this component.

Analysis of clinical characteristics and prognostic risk factors in patients with Stanford type B aortic dissection complicated with hypertension

To investigate the clinical characteristics as well as short-term and long-term prognostic factors of patients with Stanford type B aortic dissection (TBAD) with hypertension. Patients with TBAD who received thoracic endovascular aortic repair (TEVAR) admitted to Xiangyang Central Hospital from January 2014 to December 2018 were enrolled. The baseline data of patients admitted to the hospital were collected through the case management system, including gender, age, underlying diseases (hypertension, diabetes, coronary heart disease), smoking history, drinking history, duration of pain, vital signs at admission [heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP)], laboratory results [white blood cell count (WBC), platelet count (PLT), neutrophil/lymphocyte ratio (NLR), serum creatinine (SCr), C-reactive protein (CRP), D-dimer, ascending aorta diameter], etc. The clinical characteristics of TBAD patients with hypertension were analyzed. Logistic regression model and Cox proportional risk model were used to analyze the impact of hypertension on the short-term and long-term all-cause deaths after TEVAR in TBAD patients. Among 227 TBAD patients, 160 cases (70.5%) were complicated with hypertension, while 67 cases (29.5%) were not. The average age, the proportion of diabetes and coronary heart disease, and the level of SBP, DBP and SCr at admission of TBAD patients with hypertension were higher than those of TBAD without hypertension [age (years old): 53.1±11.9 vs. 42.8±14.1, combined with diabetes: 8.8% vs. 1.5%, combined with coronary heart disease: 6.3% vs. 0%, SBP (mmHg, 1 mmHg = 0.133 kPa): 147.9±18.1 vs. 136.9±15.2, DBP (mmHg): 93.9±11.9 vs. 89.1±13.8, SCr (μmol/L): 97.8±25.4 vs. 89.8±23.6, all P < 0.05]. The short-term mortality of TBAD with hypertension group was significantly higher than that of TBAD without hypertension group [6.3% (10/160) vs. 0% (0/67), χ2 = 4.386, P = 0.036]. 227 patients with TBAD were followed up for 3-66 months, with a median follow-up time of 25 months. There was no significant difference in long-term mortality between TBAD patients with and without hypertensive during discharge follow-up [13.1% (21/160) vs. 9.0% (6/67), χ2 = 0.784, P = 0.376]. Further multivariate Logistic regression analysis and Cox regression analysis did not indicate that hypertension was an independent risk factor for short-term and long-term death in TBAD patients [odds ratio (OR) and 95% confidence interval (95%CI) were 13.477 (0.541-330.215), 1.012 (0.990-1.035), both P > 0.05]. Age and HR were independent risk factors for the short-term mortality of TBAD patients [OR and 95%CI were 15.287 (1.051-226.415), 0.026 (0.002-0.840), both P < 0.05]. Age, PLT and D-dimer were independent risk factors for the long-term mortality of TBAD patients [OR and 95%CI were 1.808 (1.205-2.711), 0.555 (0.333-0.924), 1.482 (1.035-2.122), respectively, all P < 0.05]. The TBAD patients with hypertension have older age, high rates of diabetes or coronary heart disease. However, hypertension is not an independent risk factor for short-term and long-term mortality in TBAD patients.

P-OT017. Neutrophil-to-lymphocyte ratio, monocyte-to- lymphocyte ratio, and platelet-tolymphocyte ratio biomarkers in severe hemorrhagic stroke patients: Which ratio to choose as a mortality predictor?

Introduction . Several biomarkers are now being developed to predict the prognosis of stroke. Ratios of the white blood’s components are widely studied as short-term and long-term prognostic factors in patients with intensive care. Stroke, particularly severe hemorrhagic stroke, is a condition that needs intensive care that has the potential to worsen anytime in its acute period and eventually leads to death. Here, we studied the neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), and platelet-to-lymphocyte ratio (PLR) on- admission as potential predictors of in-hospital mortality in severe hemorrhagic stroke patients. Methods . It is a retrospective observational study in severe hemorrhagic stroke with conventional treatment. We reviewed the medical records to obtain clinical and laboratory data and divided the patients into survivors vs non-survivors. The laboratory data were searched for white blood cell (WBC) count, neutrophil count, lymphocyte count, monocyte count, and platelet count. The NLR, MLR, and PLR were then manually estimated. Results . Of the 30 eligible patients, 25 patients were survivors and 5 patients were non- survivors. In the laboratory examinations, the neutrophil, lymphocyte, and monocyte counts showed a significant difference between survivors and non-survivors. Furthermore, we also found that NLR and MLR were two ratios that had significant difference statistically. Also, if we used the NLR cut-off point of 5 to separate high and low NLR, we found that NLR on- admission is associated with in-hospital mortality. Conclusion . NLR and MLR on-admission were significantly different between survivors and non-survivors of severe hemorrhagic patients that were treated conventionally. Also, NLR on- admission > 5 could be associated with in-hospital mortality.

Prognostic Factors for Survival and Relapse in ANCA-Associated Vasculitis with Renal Involvement: A Clinical Long-Term Follow-Up Study.

Aim We describe the clinical pattern of ANCA-associated vasculitis (AAV) and assess long-term prognostic factors of patients and renal survival and relapse. Methods Data from 85 patients with renal biopsy-proven AAV at a single center with up to 20-year [median 16.2 years (95% CI 14.9-17.7)] follow-up were retrospectively collected. Results Overall, 55% of the patients had microscopic polyangiitis (MPA) and 45% had granulomatosis with polyangiitis (GPA). The histopathological classes were focal in 35%, crescentic in 26%, mixed in 20%, and sclerotic glomerulonephritis in 19% of the patients. As induction treatment, a combination of cyclophosphamide and corticosteroids was given to 82%, while a combination of azathioprine and corticosteroids was maintenance therapy in 79%. The twenty-year patient survival was 45%. In a multivariable analysis, age ≥58 years [hazard ratio (HR) 7.64, 95% CI 3.44-16.95] and myeloperoxidase (MPO) ANCA (HR 2.12, 95% CI 1.08-4.17) were associated with shorter patient survival time. Renal survival was 68% overall: 88% in focal, 71% in crescentic, 56% in mixed, and 37% in sclerotic class (p=0.01). Female sex (HR 0.26, 95% CI 0.10-0.73) was a predictor of improved renal survival, whereas GFR <30 ml/min and MPO-ANCA were associated with worse renal survival (HR 4.10, 95% CI 1.35-12.49 and HR 3.10, 95% CI 1.21-7.95, respectively). Relapse-free survival at 20 years was 10%. MPA was associated with a lower risk for relapse (HR 0.48, 95% CI 0.28–0.82). Conclusion We confirmed the improved patient and renal survival in AAV patients with glomerulonephritis, while relapse remained the primary challenge. Histopathological classification may be relevant for survival.

Novel Angiogenesis Markers as Long-Term Prognostic Factors in Patients With Renal Cell Cancer

ObjectiveTo evaluate Ang-2 expression alone and in combination with expression of cell proliferation and cell survival markers (MIB-1 and Bcl-2) and angiogenesis markers (VEGFR3 and CD31), and the associations of these markers with renal cell cancer (RCC) in long-term survival. Patients and MethodsOur study included 224 patients with RCC who were treated before the availability of antiangiogenic agents between 1985 and 1995, at the Pirkanmaa Hospital District in Finland. All tumor samples were reclassified and reevaluated by an experienced uropathologist, and parallel tissue microarrays (TMA) were performed for immunohistochemical analysis. Kaplan-Meier's survival estimation method and Cox proportional hazards models were used for survival analysis. ResultsThe percentage of Ang-2 expression in the tumor area varied from 0.07 to 25.65. Ang-2 expression was significantly associated with the tumor grade and stage, as well as the MIB-1, Bcl-2, and VEGFR3 expression (P = .042, P = .019, P = .039, P = .013, and P = .005, respectively). The highest Ang-2 expression predicted better survival, P < .05. High Bcl-2 and low MIB-1 expression combined with Ang-2 expression was associated with better survival. Multivariate analysis showed poorer survival in patients with low Ang-2 or high MIB-1 expressions: HR 1.89, 95% CI 1.16 to 3.08, P = .010 and HR 2.20, 95% CI 1.36 to 3.54, P = .001, respectively. ConclusionsVery high Ang-2 expression was associated with better survival in patients with RCC. Ang-2 expression correlated with tumor stage and grade, but it was still an independent prognostic factor in a multivariate analysis.

Long-Term Prognostic Factors in Patients with Significant Left Main Coronary Artery Disease

Introduction and Objectives: The natural history of patients with left main coronary artery disease (LMCAD) is largely unknown. Our objective was to analyse the predictors of long-term mortality in these patients, both those that have had surgery and those that have not undergone surgery for various reasons, in a cohort treated at a university hospital. Methods: The study included patients with significant LMCAD diagnosed through consecutive coronary angiograms from 2001 to 2009. Clinical variables, the reasons for cardiac catheterisation, therapeutic decisions and clinical evolution in long-term follow-up were analysed. Results: Of the 163 patients included in the analysis, a total of 109 (66.9%) underwent revascularisation, while the remaining 54 (33.1%) received other medical treatment. We analysed the clinical events that took place with a mean follow-up period of 54 months (IQR: 25-95). The non-revascularised group had a lower survival rate than the revascularised group in unadjusted analysis (logrank test 0.005). Age (OR 1.04, CI 1.02-1.07, p = 0.001), ventricular dysfunction (OR 2.87, CI95% 1.71-4.81, p 0.0001), clinical instability (OR 2.11, CI95% 1.08 to 4.13, p = 0.028) and above 70% severity of LMCAD (OR 1.78, CI 1.09 to 2.91, p = 0.021) were independent predictors of mortality for the entire cohort, but revascularisation was not. Conclusions: Revascularisation is associated with improved survival in patients with LMCAD, but only age, ventricular dysfunction, clinical instability and the severity of the lesion are independent predictors of long-term mortality in the unselected population.

Subclinical Peripheral Arterial Disease and Incompressible Ankle Arteries Are Both Long-Term Prognostic Factors in Patients Undergoing Coronary Artery Bypass Grafting

This study was designed to determine the prevalence of peripheral arterial disease (PAD) in candidates for coronary artery bypass grafting (CABG) and to assess the predictive value of different types of subclinical PAD (peripheral occlusive disease and medial arterial calcification [incompressible ankle arteries]). Observational studies report poor prognosis after CABG in the presence of clinical PAD, but data on subclinical PAD are scarce. We prospectively enrolled CABG candidates and measured ankle-brachial index (ABI) preoperatively. Patients were divided into four groups: clinical PAD, subclinical PAD (ABI <0.85), incompressible arteries (ABI >1.5), and no PAD. The primary end point was a composite combining death, acute coronary syndrome, stroke or transient ischemic attack (TIA), and coronary or peripheral revascularization. Secondary end points were overall and cardiovascular death, acute coronary syndrome, and stroke or TIA. Statistical analyses were performed using the Cox regression model. We consecutively enrolled 1,022 patients (mean age 66.9 +/- 9.2 years). In addition to the 14% with clinical PAD, we detected subclinical PAD in 13% and medial artery calcification in 12%. During an actuarial follow-up of 4.4 years, 81.2% of patients remained event-free. Adverse factors were (p < 0.05) supraventricular arrhythmia (odds ratio [OR] 2.5), ejection fraction <0.40 (OR 2.3), combined valvular surgery (OR 2.5), clinical PAD (OR 3.6), subclinical PAD (OR 3.3), and medial artery calcification (OR 1.9). The latter three factors were also independently predictive for overall and cardiovascular death. Beyond clinical PAD, the measurement of ABI before coronary surgery provides substantial information on long-term postoperative prognosis. To our knowledge, this is the first study highlighting the prognostic role of incompressible ankle arteries in secondary prevention.
