RESUMEN
BACKGROUND: Esophageal adenocarcinoma (EAC) has a poor prognosis; predictive markers of prognosis would facilitate advances in personalized therapy. C-reactive protein (CRP) and CRP-based scores are increasingly recommended across oncology; however, their role and value in EAC is unclear. This systematic review and meta-analysis examined CRP cut-point and scores and how they may best be applied in predicting survival in EAC. METHODS: A systematic literature search was conducted in EMBASE, Medline, Web of Science, Cochrane, Scopus and CINAHL databases, from inception to 1st October 2020. Studies reporting data from adults with EAC including adenocarcinoma of the gastro-esophageal junction (AEG), pre-treatment CRP or CRP-based score and Hazard Ratio (HR) for survival were included. QUIPS tool assessed risk of bias. Meta-analysis was undertaken. RESULTS: A total of 819 records were screened. Eight papers were included, with data for 1475 people. CRP cut-points ranged from 2.8 to 10 mg/L. The Glasgow Prognostic Score (GPS) and modified GPS were the most commonly reported scores. On meta-analysis, elevated preoperative GPS/mGPS was significantly associated with worse overall survival (hazards ratio [HR] 1.81, 95% confidence interval [CI] 1.25-2.62, p = 0.002); results were similar in subgroup analyses of multimodal treatment, M0 disease, and R0 resection. CONCLUSIONS: This is the first review to evaluate comprehensively the evidence for CRP and CRP-based scores in EAC. Meta-analysis demonstrated that elevated preoperative GPS or mGPS was significantly associated with reduced overall survival in EAC, including AEG. There is insufficient evidence to support use of CRP alone. Future studies should examine GPS/mGPS in EAC prospectively, alone and combined with other prognostic markers.

BACKGROUND: Taste and smell abnormalities (TSA) commonly occur in cancer and are associated with anorexia, early satiety, malnutrition, weight loss and reduced quality of life. A recent study found a high TSA prevalence in newly diagnosed cancer patients before treatment. This suggests that TSA may originate from the tumour itself. No previous study has examined TSA, both subjectively and objectively, in newly diagnosed, treatment-naïve cancer patients. This study aimed to address this gap. METHODS: This prospective observational study recruited consecutive, newly diagnosed, treatment-naïve patients with solid tumours at Radiation Oncology Out-patients. Self-reported taste and smell changes since becoming ill were evaluated using modified Taste and Smell Survey, and objective taste and smell tests were conducted using 'Sniffin' Sticks Olfactory Test® and Burghart Taste Strips®. Nutritional status was assessed with abridged Patient-Generated Subjective Global Assessment. RESULTS: Thirty completed the study. Seventy-four per cent had at least one TSA. Taste changes and/or abnormalities were more prevalent than smell, and subjective taste changes more common than objective abnormalities. Although less common, smell abnormalities impacted quality of life more. TSA characteristics were heterogeneous. Forty-seven per cent were at malnutrition risk. No association was found between TSA and nutritional status. CONCLUSIONS: Over two thirds had at least one TSA and almost half were at malnutrition risk. Self-reported TSA included changes in taste and smell perception, and most commonly persistent bad taste. This study demonstrated the complexity of TSA assessment and the prevalence, severity and impact of these and related symptoms in treatment-naïve cancer patients.

PURPOSE: Weight changes occur throughout the cancer trajectory. Most research has focused on changes during or after treatment, so clinical significance of change at diagnosis remains unclear. This study aimed to determine prevalence, predictors and prognostic significance of weight changes at diagnosis in outpatients with solid tumours presenting to a tertiary academic medical centre. METHODS: A retrospective study of the electronic medical record was conducted (n = 6477). Those with weight recorded within 6 months of cancer diagnosis (pre-diagnosis, T0) and 2 subsequent weights (diagnosis, T1; final visit, T2) were identified (n = 4258). Percentage weight change was categorised into four bands (0.1-2.4%; 2.5-5%; 5.01-9.9%; ≥ 10%) for gain and loss. A stable category was also included. RESULTS: Mean age is 61 ± 12.5 years. Common tumour sites: breast (17%; n = 725), prostate (16%; n = 664), lung (14%; n = 599). 15% (n = 652) had metastatic disease at T1. 98% (n = 4159) had weight change at T1. Head & neck and upper gastrointestinal cancers were significantly associated with weight loss (p < 0.001). Worst survival occurred with ≥ 10% weight gain or ≥ 10% weight loss. Overweight or obese body mass index with any percentage weight change band was associated with better overall survival. CONCLUSIONS: Most had evidence of clinically significant weight changes at diagnosis. Weight loss at diagnosis was associated with a higher risk of further weight loss. A detailed weight history at cancer diagnosis is essential to identify and intervene for those most at risk of weight change-related early mortality.

PURPOSE: Credible evidence-based diet and nutrition advice is essential for patients with cancer. This study aimed to explore what advice patients with cancer obtained before a formal dietetic visit. METHODS: A multicenter, observational study was conducted in seven hospital-based oncology services. Consecutive patients were recruited at first dietetic assessment. In addition to routine dietetic assessment, participants completed a four-item questionnaire describing diet and nutrition advice obtained since diagnosis. RESULTS: Seventy-seven patients participated. More than 80% had multiple nutrition-impact symptoms. In total, 53 (69%) obtained advice from professional and nonprofessional sources before dietetic visit. Family and friends were the most common sources of advice. More than one third got advice from (nondietetic) healthcare professionals. Most advice related to "foods to include" (61%) and "foods to avoid" (54%) in the diet. Many of the "foods to avoid" were important sources of micro- and macronutrients. Advice about dietary supplements (31%) and specific diets (28%) was common, rarely evidence-based, and frequently contradictory. Participants found it difficult to discern what advice was trustworthy and reliable. Despite this, most followed the advice. CONCLUSION: The majority of patients received diet and nutrition advice before first dietetic visit. Most of this came from nonprofessional sources. Any advice from nondietetic healthcare professionals was inconsistent or vague. This was mainly related to the avoidance and/or inclusion of particular foods and was often contradictory. Nevertheless, patients usually followed such advice fully. To help manage their frequent nutrition-impact symptoms and resolve the contradictory advice they had received, many expressed the need for earlier professional dietetic consultation.

Cutaneous malignant melanoma (CMM) is one of the most immunogenic types of cancer, with a 6-fold higher rate of spontaneous regression than any other malignancy. In addition to responsiveness to different immunotherapies, the immunogenicity of CMM highlights the important role of the host immune system in the response to CMM. The present study aimed to explore the role of two functional promoter polymorphisms [IL6 -174G>C (rs1800785) and TNFA -308G>A (rs1800629)] in the regulation of the genes encoding the pro-inflammatory cytokines interleukin (IL)-6 and tumor necrosis factor-α, specifically in patients with CMM. A total of 76 patients with CMM and 200 control subjects were genotyped using PCR-restriction fragment length polymorphism. The genotype frequencies for both single nucleotide polymorphisms (SNPs) did not differ significantly between the patients and controls (P=0.358 and P=0.810 for IL6 and TNFA, respectively). However, compared with carriers of C-allele genotypes (CG+CC), patients with the IL6 -174GG genotype exhibited more advanced melanoma (Clark scale ≥3; P=0.037) and shorter survival times, particularly those who worked outdoors (in conditions with increased sunlight exposure; P=0.016). Furthermore, the serum IL-6 levels of patients with CMM were significantly higher than those of the control subjects, which were associated with unfavorable blood and serum characteristics and tumor progression (development of new distant metastases; P=0.004), and with a shorter overall survival time (P=0.042). Using a Cox proportional hazard model, the IL6 -174GG genotype was found to be an independent prognostic factor for reduced survival time (P=0.030), together with sex (being male; P=0.004) and occupations with higher exposure to sunlight (P=0.047). In conclusion, the results of the present study indicated that the promoter polymorphisms IL6 -174G>C and TNFA -308G>A are not predisposing factors for CMM. However, the IL6 -174G>C SNP and IL-6 serum concentrations are likely to influence the progression of the disease, and the GG genotype and higher IL-6 serum levels may indicate shorter survival.
RESUMEN
INTRODUCTION: Malnutrition (MN) often goes unrecognized due to ineffective screening techniques. Published standards for multidisciplinary care exist but no consensus on best nutritional assessment for hospitalized patients. Malnutrition is common in cancer and adversely affects clinical outcomes. The Cleveland Clinic Nutrition Therapy Department used in-house criteria to classify MN in hospitalized patients. This study aimed to evaluate the registered dietitian (RD)'s role, the use of these criteria in the acute care palliative medicine unit (ACPMU), and investigate MN prevalence and severity among admitted patients with cancer. METHODS: Electronic medical records were reviewed for newly admitted patients with cancer to the ACPMU with a first time RD consult and completed nutritional therapy assessment. Physician (MD) assessments were derived from admission notes. Cox regression model assessed the association of MN prevalence and severity with survival. McNemar's test determined whether a prevalence difference existed between RD and MD. RESULTS: Variations existed in criteria used to identify MN. Seventy percent had MN, with the majority (61%) classed as moderate to severe. Prevalence (hazard ratio [HR]: 1.88; P = .002) and severity (HR: 1.22; P = .006) were associated with significantly increased mortality. Evaluations by RD and MD were highly congruent, but MDs underrecorded nutritional status. CONCLUSION: Malnutrition was prevalent and clinically important, even in those on nutritional support. Variations in MN identification were common. Physicians underrecorded MN but were accurate for prevalence and severity when recorded. The data confirm the RD's important role in MN assessment. Comparable clinical practice and better communication between physicians and dietitians should improve cancer care and optimize quality of life.
