Predicting the Prognosis of Gastric Cancer by Albumin/Globulin Ratio and the Prognostic Nutritional Index

Abstract

Background: Albumin-to-globulin ratio (AGR) and the prognostic nutrition index (PNI) are used to assess the nutritional status and severity of disease for a cancer patient. However, the clinical significance of combining these two predictors in gastric cancer (GC) remains unclear. This study evaluated the prognostic value of pretreatment serum AGR and the PNI for GC.

Methods: A total of 273 patients with GC, diagnosed between January 2010 and January 2014, were enrolled. The association of AGR, PNI with clinicopathological characters and prognosis were assessed by Cox regression and Kaplan–Meier methods.

Results: Both low AGR group and low PNI group had poor overall survival (OS) and progression-free survival (PFS) (all p?<?0.001), while patients with low AGR and PNI had the lowest OS rate. Multivariate analyses revealed that AGR (for OS HR?=?0.657, 95%CI: 0.449–0.962, p?=?0.031; for PFS HR?=?0.684, 95%CI: 0.528–0.895, p?=?0.035) was an independent prognostic factor for OS and PFS in patients with GC, and PNI was verified as a predictor for OS (HR?=?0.782, 95%CI: 0.503 –0.997, p?=?0.048).

Conclusions: Low level of pretreatment AGR and PNI may be independent prognostic factors for patients with GC, and patients with both factors indicated the worst OS.     

Prognostic Value of the Geriatric Nutritional Risk Index in Patients Exceeding 70 Years Old with Esophageal Squamous Cell Carcinoma

Abstract

To investigate the prognostic value of the Geriatric Nutritional Risk Index (GNRI) in esophageal squamous cell carcinoma (ESCC) patients treated with radiotherapy (RT) or definitive concurrent chemoradiotherapy (dCRT). Fifty-two ESCC patients were included from July 2014 to December 2018. RT was delivered at a dose of 1.8–2.0?Gy per day to a total dose of 50–60?Gy. Tumor response was assessed using the RECIST 1.1 system. Overall survival (OS) and progression-free survival (PFS) were calculated and compared with the Kaplan–Meier method. Multivariate analysis of predictive factors of response and survival was performed using a logistic regression and a Cox model, respectively. In multivariate analysis, GNRI score (HR 0.278, P?=?0.036) was the only independent prognostic factor for tumor response. As for survival outcomes, GNRI score (OS: HR 0.505, P?=?0.028; PFS: HR 0.583, P?=?0.045) and treatment modality (OS: HR 0.356, P?=?0.015; PFS: HR 0.392, P?=?0.0014) were both independent prognostic factors for better OS and PFS. Additionally, there was no correlation between GNRI score and treatment modality (Spearman’s ρ?=?0.200; P?=?0.154). In conclusion, routine use of the GNRI criteria may help in the risk stratification of elderly patients undergoing RT/dCRT. The dCRT treatment could provide survival benefits for elderly ESCC patients.     

Prognostic Nutritional Index Predicts Outcomes of Patients after Gastrectomy for Cancer: A Systematic Review and Meta-Analysis of Nonrandomized Studies

Objective: The primary aim of this systematic review was to evaluate the survival predication value of preoperative prognostic nutritional index (PNI) in patients with gastric cancer. The second aim was to explore the relationship between preoperative PNI and clinicopathological features.

Methods: A systematic search of the electronic databases identified studies that investigated the association of preoperative PNI with short or long-term outcomes among patients after gastrectomy for cancer. Qualitative and quantitative analysis of results was conducted.

Results: Twenty-five studies with a total of 14,403 patients with gastric cancer met inclusion criteria for this review. Pooled analysis demonstrated that low preoperative PNI was associated with significantly reduced overall survival (HR 1.81, 95% CI: 1.56–2.09; P?=?0.000), cancer-specific survival (HR 1.61, 95% CI: 1.24–2.10; P?=?0.000), and recurrence-free survival (HR 1.82, 95% CI: 1.20–2.77; P?=?0.005). In addition, risk of postoperative complications (POCs) and mortality was significantly higher in patients with lower preoperative PNI (RR 1.77, 95% CI: 1.44–2.17; P?=?0.000 and RR 5.14, 95% CI: 2.23–11.79; P?=?0.000, respectively).

Conclusion: This study suggests that patients with low preoperative PNI may have a high incidence of POCs and poor prognosis following gastrectomy for cancer.     

Prognostic Value of Prealbumin in Liver Cancer: A Systematic Review and Meta-Analysis

Abstract

Accumulated studies have reported the prognostic significance of prealbumin in liver cancer, but the results were not conclusive. The aim of this study was to evaluate the association between pretreatment serum prealbumin and clinical outcome of liver cancer patients through a meta-analysis. We comprehensively searched EMBASE, PubMed, Web of Science and the Cochrane library to identify eligible studies. The pooled hazard ratios (HRs) and their 95% confidence intervals (CIs) were utilized to evaluate the prognostic value of pretreatment serum prealbumin in overall survival (OS) and recurrence-free survival (RFS) of liver cancer patients. A total of 3470 patients from 10 eligible studies were finally included for analysis. The combined effects of prealbumin on liver cancer patients’ OS and RFS were HR?=?1.83, 95% CI: 1.46–2.30, P?<?0.001 and HR?=?1.47, 95% CI: 1.01–2.14, P?=?0.045, respectively. Sensitivity and subgroup analysis showed that the pooled HR of prealbumin on liver cancer patients’ OS was stable. Since potential publication bias was identified in the OS studies, the trim-and-fill method therefore was performed to explore publication bias, and the results showed reliability. This meta-analysis shows that low pretreatment serum prealbumin is significantly associated with poor prognosis of liver cancer patients.     

Comparison of Preoperative Nutritional Indexes for Outcomes after Primary Esophageal Surgery for Esophageal Squamous Cell Carcinoma

Background: This study aimed to compare the controlling nutritional status (CONUT) score, prognostic nutritional index (PNI), and geriatric nutritional risk index (GNRI) for predicting postoperative outcomes in patients with esophageal squamous cell carcinoma undergoing esophagectomy. Methods: We retrospectively reviewed the data of 1265 consecutive patients who underwent elective esophageal surgery. The patients were classified into no risk, low-risk, moderate-risk, and high-risk groups based on nutritional scores. Results: The moderate-risk (hazard ratio [HR]: 1.55, 95% confidence interval [CI]: 1.24–1.92, p < 0.001 in CONUT; HR: 1.61, 95% CI: 1.22–2.12, p = 0.001 in GNRI; HR: 1.65, 95% CI: 1.20–2.26, p = 0.002 in PNI) and high-risk groups (HR: 1.91, 95% CI: 1.47–2.48, p < 0.001 in CONUT; HR: 2.54, 95% CI: 1.64–3.93, p < 0.001 in GNRI; HR: 2.32, 95% CI: 1.77–3.06, p < 0.001 in PNI) exhibited significantly worse 5-year overall survival (OS) compared with the no-risk group. As the nutritional status worsened, the trend in the OS rates decreased (p for trend in all indexes < 0.05). Conclusions: Malnutrition, evaluated by any of three nutritional indexes, was an independent prognostic factor for postoperative survival.     

Impact of Weight Loss During Chemotherapy in Chinese Patients with Unresectable Pancreatic Cancer

Background: Weight loss is frequently observed in pancreatic cancer patients. We aimed to study the prognostic impacts of weight loss early during chemotherapy.

Methods: A total of 72 patients of Chinese ethnicity with unresectable pancreatic cancer who underwent chemotherapy were reviewed. Critical weight loss (CWL) was defined as weight loss ≥ 5% within one month after treatment. The prognostic impact of weight loss and CWL were analyzed.

Results: 47 patients (65.3%) had weight loss after one month of treatment, with 14 (19.4%) suffering from CWL. Baseline characteristics were similar between patients with and without CWL. The median OS and Time-to-treatment-failure (TTF) of patients with CWL were shorter than those without CWL (OS: 4.8?months [CWL] versus [vs.] OS 7.1?months [No CWL]; TTF 1.6?months [CWL] vs. 3.2?months [No CWL]; both P?<?0.01). CWL was an independent adverse prognosticator for OS (Hazard Ratio [HR]?=?2.50; P?=?0.01) and TTF (HR = 2.71; P?<?0.01). Other independent prognosticators for OS were serum albumin <35?mg/dl and CA19-9?≥?1000?IU/ml, while CWL was the only independent prognosticator for TTF (HR 2.71 [95% CI 1.33–5.52]; P?<?0.01).

Conclusions: Development of CWL in early course of chemotherapy was associated with worse prognosis in Chinese patients with unresectable pancreatic cancers.     

中性粒细胞与淋巴细胞比率评估胃癌预后的Meta分析

目的分析探讨中性粒细胞与淋巴细胞比率(neutrophil-lymphocyte ratio, NLR)对胃癌患者预后评估的价值。 方法采用循证医学的meta分析研究。首先,从Embase、Medline和Web of Science数据库中检索关键词gastric cancer、stomach cancer、gastric carcinoma、stomach carcinoma、gastric neoplasm、stomach neoplasm、neutrophil和lymphocyte。然后,根据各纳入研究的总生存率(overall survival, OS)和无进展生存期(progression-free survival, PFS)/无疾病生存期(disease-free survival, DFS)合并生存危险比(hazard ratio, HR)的异质性,决定用固定或随机效应模型计算OS和PFS/DFS的合并HR。若合并HR>1,且其95%可信区间(confidence interval, CI)也>1, 则为NLR升高与胃癌患者OS或PFS/DFS的降低有显著联系。 结果收集18篇文献共纳入5 065例胃癌患者进行meta分析。升高的NLR与OS降低存在显著关联(HR为1.79,95%CI 1.54~2.08)。亚组分析中,胃癌多种治疗方案组和化疗组NLR升高均与OS降低存在显著关联[HR分别为1.84, (95% CI 1.48~2.29)和1.69, (95% CI 1.41~2.03)];而NLR≤3.2组和NLR>3.2组亦均与OS的降低存在显著关联[HR分别为1.80, (95% CI 1.46~2.23)和1.93, (95% CI 1.58~2.36)]。在胃癌患者OS的单因素meta回归分析中, 发表年份、种族、NLR临界值、治疗方案、患者数、进展期患者比例和男性比例都不是引起胃癌患者异质性来源的可能原因(P值分别为0.585、0.887、0.731、0.697、0.613、0.877、0.775)。 结论胃癌患者中升高的NLR与OS降低存在显著的关联,NLR可作为评价胃癌患者预后的标志物。     

Malnutrition at Diagnosis Predicts Mortality in Patients With Systemic Immunoglobulin Light‐Chain Amyloidosis Independently of Cardiac Stage and Response to Treatment

Background: Nutrition status was shown to be a prognostic factor in patients with immunoglobulin light‐chain amyloidosis (AL). However, malnutrition was associated with cardiac involvement, thus suggesting potential interactions. This study aim was to clarify the association among nutrition status, cardiac stage, and mortality in AL. Methods: One hundred twenty‐eight consecutive newly diagnosed, treatment‐naïve patients with histologically confirmed AL were enrolled. Anthropometric, biochemical, and clinical variables were assessed. Results: At multivariable Cox proportional hazard analysis, body mass index (BMI) < 22 kg/m² (HR = 1.98, 95% CI = 1.09–3.56) and unintentional 6‐month weight loss (WL) ≥ 10% (HR = 1.94, 95% CI = 1.00–3.74) resulted in independent predictors of survival after controlling for hematologic response to treatment (HR = 0.27, 95% CI = 0.14–0.53) and cardiac stage (Mayo Clinic stage III, HR = 4.42, 95% CI = 2.61–7.51). There was no effect modification of malnutrition on mortality by cardiac stage (P for interaction = .27). Moderate and severe malnutrition (prevalence: 21.9% and 7.8%, respectively) similarly increased the risk of death (HR = 3.09, 95% CI = 1.75–5.46; 2.88, 95% CI = 1.23–6.72, respectively). Conclusions: In AL, malnutrition at diagnosis is a frequent comorbidity that affects the prognosis independently of hematologic response to treatment and cardiac stage. Nutrition status should be systematically considered in future intervention trials in AL. Nutrition support trials are warranted.     

Associations of smoking with cardiometabolic profile and renal function in a Romanian population-based sample from the PREDATORR cross-sectional study

Background: The impact of smoking on morbidity is well known, but in Romania, limited data are available regarding the smoking prevalence and relationship with cardiometabolic profile and kidney function.

Objectives: To assess the association of smoking with cardiometabolic traits and kidney function, in a Romanian population-based sample from the PREDATORR study.

Methods: PREDATORR was an epidemiological cross-sectional study. Between 2012 and 2014, participants were randomly selected from the lists of general practitioners and enrolled if they were aged 20 to 79 years, born and living in the past 10 years in Romania. Sociodemographic and lifestyle characteristics were collected through interviewer-administered questionnaires.

Results: Overall, 2704 participants were included in the analysis, 18% of them being current smokers and 30.8% former smokers. Current smokers compared to non-smokers had higher total cholesterol (220.6?±?50.4 versus 213.9?±?86.8?mg/dl, P?=?0.017), LDL-cholesterol (137.8?±?45.2 versus 130.7?±?83.7?mg/dl, P?=?0.004) and glomerular filtration rate (96.9?±?16.8 versus 90.7?±?19.1?ml/min/1.73?m², P?<0.001) in women and higher triglycerides (170.7?±?129.8 versus 144.3?±?94.2?mg/dl, P?=?0.007), glomerular filtration rate (97.6?±?17 versus 90.3?±?18?ml/min/1.73?m², P?P?=?0.002) in men. Active smoking was associated with hypercholesterolaemia [OR: 1.40 (95% CI: 1.01–1.96), P?=?0.04] and low HDL-cholesterolaemia [OR: 1.39 (95% CI: 1.01–1.91), P?=?0.04] and negatively associated with overweight/obesity [OR: 0.67 (95% CI: 0.48–0.94), P?=?0.02]. Male former smokers had higher prevalence of abdominal obesity (82.4% versus 76.4%, P?=?0.02), hypertriglyceridaemia (43.6% versus 35.6%, P?=?0.01), hypertension (64% versus 56.4%, P?=?0.01) and ischaemic vascular disease (40.5% versus 30.9%, P?=?0.003) than male non-smokers.

Conclusion: The PREDATORR study showed a high prevalence of smoking in the adult Romanian population providing data on the association of smoking with cardiometabolic traits.     

Prognostic Impact of Nutritional Status Assessed by the Controlling Nutritional Status (CONUT) Score in Patients with Surgically Treated Renal Cell Carcinoma

Purpose: The prognostic role of the controlling nutritional status (CONUT) score in renal cell carcinoma (RCC) has not been evaluated. The aim of the current study was to clarify the prognostic significance of the CONUT score in Korean patients with surgically treated RCC.Materials and methods: A database of 1,881 patients with surgically treated RCC from a multiinstitutional Korean collaboration between 1999 and 2015 was analyzed. The preoperative CONUT score was calculated from serum albumin, total cholesterol concentrations, and total lymphocyte count. Clinicopathological variables and survival rates were compared between the CONUT score groups.Results: A high CONUT score was associated with older age, lower body mass index, lower preoperative prognostic nutritional index, and presence of diabetes or hypertension (each P?<?0.001). Regarding pathologic features, a high CONUT score was associated with aggressive tumor characteristics including large tumor size, advanced stage, high nuclear grade, lymphovascular invasion, and sarcomatous differentiation (each P?<?0.001). Multivariate Cox regression analysis indicated that a high CONUT score (≥ 2) was an independent predictor of cancer-specific mortality (hazard ratio, 1.892; 95% CI: 1.118–3.201; P?=?0.018).Conclusion: The CONUT score, an easily measurable immune-nutritional biomarker, may provide useful prognostic information in patients with surgically treated RCC.     

Aldehyde dehydrogenase serves as a biomarker for worse survival profiles in ovarian cancer patients: an updated meta-analysis

Background

The purpose of this comprehensive meta-analysis was to assess the association of aldehyde dehydrogenase (ALDH) expression with overall survival (OS) and disease-free survival (DFS)/progression-free survival (PFS) in ovarian cancer patients.

Methods

Systematic searches of Pubmed databases was performed to identify relevant literature published before February 28, 2018. A total of 14 studies (13 articles) with 2210 ovarian cancer patients were pooled. All included studies were performed by using Immunohistochemistry (IHC) for detection of ALDH expression. Hazard ratio (HR) and 95% confidence interval (CI) were extracted from included studies to evaluate the correlation of ALDH expression with OS and DFS/PFS.

Results

High expression of ALDH was associated with worse OS (HR: 1.43; 95% CI: 1.18–1.73) and poor DFS/PFS (HR: 1.55, 95% CI: 1.12–2.14). No evidence of publication bias was observed in OS (Begg’s test, P?=?0.113; Egger’s test, P?=?0.355) and DFS/PFS (Begg’s test, P?=?0.655; Egger’s test, P?=?0.189) in ovarian cancer patients. The subgroup of studies with cut-off value of low expression showed that high expression of ALDH was correlated with poor OS (HR: 1.36; 95% CI: 1.14–1.62) and DFS/PFS (HR: 1.79; 95% CI: 1.45–2.20) in ovarian cancer patients, with no observed heterogeneity (OS: I² =?0%, P?=?0.45; DFS/PFS: I² =?0%, P?=?0.55).

Conclusion

In conclusion, high expression of ALDH is correlated with worse survival profiles in ovarian cancer patients, indicating that ALDH might act as a potential molecular biomarker for prognosis of ovarian cancer.

     

Prognostic Role of the Prognostic Nutritional Index in Pancreatic Cancer: A Meta-analysis

Objective: The prognostic nutritional index (PNI) has been reported to play an important prognostic role in various malignancies. Here we performed a meta-analysis to explore the predictive value of PNI in pancreatic cancer (PC).

Methods: Clinical studies about PNI and prognosis in PC were retrieved from Pubmed, Embase, Web of Science and Cochrane Libarary updated on 31 December 2017. Stata 12 was used to compute pooled hazard radio (HR) and 95% confidence interval (CI) to estimate the relationship between PNI and overall survival (OS).

Results: Ten studies with 2064 patients were eligible for final analysis. The pooled HR (1.48, 95%CI: 1.32–1.66, I ² = 25.5% P?=?0.201）revealed that low PNI was related to poor prognosis in patients with PC. The significant relationship between PNI and prognosis was not affected by subgroup analysis based on tumor stage, treatment method, sample size, cutoff value, HR data source and study quality.

Conclusion: Our meta-analysis suggests PNI maybe a potential prognostic indicator for patients with PC.     

Dairy Products and Cancer Risk in a Northern Sweden Population

Abstract

The role of dairy products in cancer is unclear. We assessed consumption of fermented milk, non-fermented milk, cheese, and butter, estimated from semi-quantitative food frequency questionnaires, in relation to prospective risk of breast, prostate, colorectal, smoking-, and obesity-related cancers in 101,235 subjects, including 12,552 cancer cases, in the population-based Northern Sweden Health and Disease Study. Most analyses (n?=?20) rendered null results. In men, we observed an increased prostate cancer risk among high-consumers of cheese (hazard ratio (HR) for highest vs. lowest quintile (Q5–Q1), 1.11; 95% CI, 0.97–1.27; P^trend?=?0.013). In women, high-consumers of cheese had a decreased risk of overall cancer (HR Q5–Q1, 0.95; 95% CI, 0.88–1.04; P^trend?=?0.039), smoking-related (HR Q5–Q1, 0.84; 95% CI, 0.72–0.97; P^trend ≤ 0.001), and colorectal cancers (HR Q5–Q1, 0.82; 95% CI, 0.63–1.07; P^trend?=?0.048). Butter yielded a weak decreased obesity-related cancer risk in women (HR Q5–Q1, 0.91; 95% CI, 0.81–1.02; P^trend?=?0.049). Fermented milk yielded HRs below zero in women, but with no clear linear associations. In conclusion, this study does not support any major adverse or beneficial effects of fermented milk, non-fermented milk, cheese, and butter in the diet from a cancer risk perspective.     

Cancer-Related Fatigue,Laboratory Markers as Indicators for Nutritional Status among Patients with Colorectal Cancer

Abstract

Our objective was to determine the relationship between cancer-related fatigue (CRF), laboratory markers, and nutritional status among patients with colorectal cancer (CRC). A cross-sectional design was used. A sample of 80 participants diagnosed with CRC participated and completed the study's surveys including the patient-generated subjective global assessment (PG-SGA), cancer fatigue scale (CFS), laboratory markers sheet, and patient-related factors sheet. Positive relationships were identified between PG-SGA and CRF, physical fatigue, cognitive fatigue, WBC, and calcium level (r?=?0.781, 0.820, 0.751, 0.680, and 0.710; P?=?0.001 respectively). Negative relationships were found between PG-SGA and sodium, potassium, and hemoglobin levels (r = ?0.801, ?0.761, and ?0.810; P?=?0.001 respectively). The regression analysis revealed an R₂?=?0.610 (adjusted R₂?=?0.590), F (4.58, P?<?0.001). Finally, the above-mentioned independent variables accounted for 61.0% of the variance in PG-SGA. Patients with CRC are experiencing nutritional problems during their treatment. Cancer-related fatigue and other laboratory markers are considered indicators for nutritional status. Clinical dietitians and oncology nurses can work together to monitor these parameters and provide clinical treatment when needed.     

Full Mini Nutritional Assessment and Prognosis in Elderly Patients with Pulmonary Tuberculosis

Objective: Malnutrition is observed frequently in elderly patients with pulmonary tuberculosis (TB). Full Mini Nutritional Assessment (full MNA) is a useful method of measuring nutrition status for elderly person. The objective of this study is to examine the relationship between full MNA and the mortality of elderly patients with pulmonary TB.

Methods: We evaluated 53 elderly patients with pulmonary TB. The nutrition risk assessment was carried out using full MNA.

Results: A receiver operating characteristic (ROC) curve was generated for further analysis of the prognostic value of full MNA score. The area under the curve was 0.856 (95% confidence interval [CI], 0.751–0.961). We used the maximum Youden index to obtain optimal cutoff values for full MNA score for prognostic assessment in elderly patients with pulmonary TB. For predicting the risk of mortality, the optimal cutoff value for full MNA score was 13.75. Based on this cutoff value, the Cox proportional hazard model was applied to assess the ability of full MNA score < 14 to predict the prognosis of elderly patients with pulmonary TB. Multivariate analysis identified age (hazard ratio [HR] = 1.114, 95% CI, 1.018–1.219, p = 0.019) and full MNA score < 14 (HR = 9.038, 95% CI, 1.064–76.768, p = 0.044) to be significant independent prognostic factors for survival.

Conclusion: Severe malnutrition, as defined by full MNA score < 14, was a predictor of high mortality.     

Higher prepregnancy body mass index is a risk factor for developing preeclampsia in Maya-Mestizo women: a cohort study

Aim: Preeclampsia and obesity are two closely related syndromes. The high maternal prepregnancy body mass index (BMI) is a risk factor for present preeclampsia, independently of the ethnic background of the studied population. The aim of this study was to analyse in a prospective cohort study the relation between prepregnancy BMI and development of preeclampsia in Maya-Mestizo women.

Design: This is a prospective cohort study of 642 pregnant women that were included in the first trimester of the pregnancy (gestational age ≤12 weeks at the first antenatal visit) and all of them were of Maya-Mestizo ethnic origin from the state of Yucatán, México. We assessed the potential risk factors for preeclampsia and documented the prepregnancy BMI (kg/m²) that was based on measured height and maternal self-report of prepregnancy weight at the initial visit. Besides, in the antenatal visit we documented if the pregnant women developed preeclampsia.

Results: Of the 642 pregnant Maya-Mestizo women, 49 developed preeclampsia, with an incidence of 7.6% (44.9% had severe and 55% mild). The prepregnancy BMI was higher in women with developed preeclampsia than in those with normal pregnancies. Women with overweight or obesity in comparison with normal weight presented a RR?=?2.82 (95% CI: 1.32–6.03; P?=?0.008) and RR=?4.22 (95% CI: 2.07–8.61; P?=?0.001), respectively.

Conclusions: Our findings expand the previous studies to show that the higher prepregnancy BMI is a strong, independent risk factor for preeclampsia.     

Potato Consumption and Risk of Colorectal Cancer in the Norwegian Women and Cancer Cohort

Potatoes are the fourth most plentiful food crop in the world, yet the scientific literature on the health effects of potato consumption is scarce. This study aimed to investigate the association between potato consumption and the risk of colorectal cancer (CRC) among 79,778 women aged 41–70, in the Norwegian Women and Cancer study. Information on diet, lifestyle, and health was collected by questionnaire. CRC cases (n = 912) were identified through registry linkage. Adjusted Cox proportional hazard models were used to estimate the association between potato consumption and the risk of CRC. Results showed that high potato consumption was associated with a higher risk of CRC (hazard ratio [HR]: 1.32, 95% confidence interval [CI]: 1.10, 1.60 for ≥3 potatoes per day versus 0–7 potatoes per week). The same association was found for rectal cancer (HR: 1.68, 95% CI: 1.19, 2.36), and same tendencies were found for colon cancer (HR: 1.20, 95% CI: 0.96, 1.50). When stratified by body mass index (BMI) (<25 and ≥25 kg/m²), significant associations were found with BMI <25 kg/m² for CRC (HR: 1.48, 95% CI: 1.15, 1.89) and rectal cancer (HR: 1.95, 95% CI: 1.25, 3.06). No significant interaction between potato consumption and BMI (P = 0.49) was found.     

Nutritional,immunological and antioxidant defense status of outpatients diagnosed with colorectal cancer – a case–control study of the little-studied population

Abstract

This cross-sectional study was conducted to investigate nutritional and immunological status of colorectal cancer (CRC) patients in a little-studied population from developing country, Pakistan. Data on 81 CRC patients and 37 healthy controls (HCs) were collected on nutritional status, nutrient intake, percent body fat (%BF), selected immunological parameters, phytochemical index (PI), healthy eating index (HEI), and prognostic nutrition index (PNI). Blood samples were used for immunological and antiradical defense potential (expressed as 50% hemolysis time; HT₅₀). Results show 40/81 (49.4%) patients reported weight loss in past 3–6?mo, Significant differences were found in HEI values between patients vs. HCs, and between patients in low vs. high PNI groups (P, for all trends <0.05). Patients in the higher PNI group were heavier, had higher % BF, higher energy intake, and higher PI score as compared to patients in the low PNI group (P?<?0.05). Low PNI was positively associated with non-significantly lower CD4:CD8 ratios, higher B-cells and NK cells (P, for all trends >0.05), but with significantly higher hs-CRP levels, and lower HT₅₀ values (P, for all trends <0.001). In conclusion, CRC patients in a little-studied population have compromised nutritional and immunological health with lower HEI and PNI scores.     

Time to deterioration of patient-reported outcomes in non-small cell lung cancer: exploring different definitions

Purpose

The clinical relevance of different time-to-deterioration (TTD) definitions for patient-reported outcomes were explored.

Methods

TTD definitions differing by reference score and deterioration event were used to analyse data from the phase 3 FLAURA trial of first-line osimertinib versus erlotinib or gefitinib in patients with EGFR-mutated advanced non-small cell lung cancer. Pre-specified key symptoms were fatigue, appetite loss, cough, chest pain and dyspnoea, scored using the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-LC13 questionnaires (≥?10-point difference?=?clinically relevant).

Results

No significant treatment differences in TTD (distributions) were observed using definitions based on transient or definitive deterioration alone. TTD definitions based on definitive, sustained deterioration, with death not included as an event, yielded a significant treatment difference for dyspnoea (hazard ratio [HR] 0.71; P?=?0.034) when baseline was the reference, and for cough (HR 0.70; P?=?0.009) and dyspnoea (HR 0.71; P?=?0.004) when best previous score was the reference. With death included as an event, treatment differences were significant for dyspnoea (HR 0.70; P?=?0.025) when baseline was the reference, and for cough (HR 0.70; P?=?0.011), dyspnoea (HR 0.71; P?=?0.003) and chest pain (HR 0.71; P?=?0.038) when best previous score was the reference. Irrespective of definition, TTD for appetite loss and fatigue did not differ significantly between arms.

Conclusion

This exploratory work showed that different TTD definitions yield different magnitudes of treatment difference, highlighting the importance of pre-specifying TTD definitions upfront in clinical trials.

Natural histories of metabolite BMI phenotypes and their impacts on cardiovascular disease risk over a decade-long follow-up

PurposeThe prognostic significance of obesity phenotypes is under debate, and few studies have characterized their transition trajectories. This study examined the natural courses of different phenotypes and their associations with cardiovascular disease risks.MethodsA total of 1827 participants were followed for 14 years and re-evaluated every 4–5 years. Four metabolite BMI phenotypes were determined according to overweight or obesity (BMI ≥ 24 kg/m²) and metabolic health status (≤1 Adult Treatment Panel III criteria, excluding waist circumference). Cardiovascular risks were assessed by evaluating baPWV and hypertension, diabetes and chronic kidney disease (CKD) development.ResultsMore than 20% of participants changed their initial phenotypes within 5 years. One-third of healthy overweight/obese (MHO) individuals became unhealthy, and only 10.6% regressed to a healthy normal weight (MHN) at the end of follow-up. Compared with MHN participants, MHO participants had higher odds of increased baPWV (OR: 1.18, 95% CI, 0.42–3.33) and increased risks of incident hypertension (HR: 1.87, 95% CI, 1.18–2.98) and diabetes (HR: 2.61, 95% CI, 1.35–5.03). Metabolic deterioration during follow-up resulted in an increased risk of baPWV and clinical diseases.ConclusionsThe natural trajectory of metabolite BMI phenotypes is time-varying, and interventions for both healthy and unhealthy overweight/obese individuals should be widely recommended.
