Nutrition in Cancer Therapy in the Elderly-An Epigenetic Connection?

Prognostic impact of muscle mass loss in elderly patients with oesophageal cancer receiving neoadjuvant chemoradiation therapy

BACKGROUND

We aimed to identify the impact of muscle mass on locally advanced oesophageal cancer (LAEC) in elderly patients receiving neoadjuvant chemoradiation therapy (NACRT).

METHODS

We reviewed the medical records of 345 patients diagnosed with LAEC who underwent NACRT and surgery. Physical variables, including height, weight, skeletal muscle mass, and laboratory values, were obtained before and after NACRT. Body mass index (BMI, kg/m2), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and prognostic nutritional index (PNI) were calculated as height/(weight)2, ANC/ALC, platelet count/ALC, and (10 × albumin + 0.05 × ALC), respectively. The cutoff for low muscle mass was 43.0 cm2/m2 for BMI below 25 kg/m2 and 53.0 cm2/m2 for BMI 25 kg/m2 or higher. The skeletal muscle index (SMI) was defined as skeletal muscle area/(height)2 (cm2/m2). The ΔSMI (%/50 days) was defined as (SMI after NACRT - SMI before NACRT)/interval (days) × 50 (days) to compare changes over the same period. The excessive muscle loss (EML) group was defined as patients with ΔSMI ≤-10% following NACRT. An elderly patient was defined as aged ≥65 years. The primary outcome measure was overall survival (OS).

RESULTS

During a median follow-up of 32.8 months (range, 2.0-176.2), 192 patients died, with a median OS of 50.2 months. Elderly patients did not show inferior OS (young vs. elderly, 57.7% vs. 54.0% at 3 years, P = 0.247). 71.0% and 87.2% of all patients had low muscle mass before and after NACRT, respectively, which was not associated with OS (P = 0.270 and P = 0.509, respectively). Inflammatory (NLR and PLR) and nutritional index (PNI) values or their changes did not correlate with OS. However, the EML group had worse OS (41.6% vs. 63.2% at 3 years, P < 0.0001). In the multivariate analysis, EML was also a significant prognostic factor for OS. In the subgroup analysis by age, EML was a strong prognostic factor for OS in the elderly group. The 3-year OS was 36.8% in the EML group and 64.9% in the non-EML group (P < 0.0001) in elderly patients, and 47.4% and 62.1% (P = 0.063) in the young patients. In multivariate analysis of each subgroup, EML remained prognostic only in the elderly group (P = 0.008).

CONCLUSIONS

EML may be strongly associated with a deteriorated OS in elderly patients undergoing NACRT, followed by surgery for LAEC. The strategies for decreasing muscle loss in these patients should be investigated.

Exploring the potential of VGLL3 methylation as a prognostic indicator for intracranial aneurysm with gender-specific considerations

DNA methylation is widely recognized to play a role in intracranial aneurysm (IA) pathogenesis. We investigated the levels of methylation of vestigial-like 3 (VGLL3) in IA and explored its potential as a prognostic indicator. A total of 48 patients with IA and 48 healthy controls were included in the present study. Methylation levels of CpG sites were assessed using bisulfite pyrosequencing, and levels of VGLL3, TEAD, and YAP in the blood were measured by real-time quantitative polymerase chain reaction testing. VGLL3 methylation was significantly higher in controls than in IA patients (P=0.001), and this phenomenon was more pronounced in females (P<0.001). Compared with the control group, the expression levels of VGLL3 and TEAD in the blood of IA patients were significantly increased, while YAP was significantly decreased. VGLL3 methylation was positively correlated with HDL (P=0.003) and female Lpa concentration (r = 0.426, P=0.03), and was also negatively correlated with age (P=0.003), APOE (P=0.005), and VGLL3 mRNA expression (P<0.001). Methylation and mRNA expression of VGLL3 may serve as indicators of IA risk in females (AUC = 0.810 and 0.809). VGLL3 methylation may participate in the pathogenesis of IA by regulating the expression of the VGLL3/TEAD/YAP pathway, and its gene methylation and expression levels have IA risk prediction value.

Experiences of Family Caregivers Providing Home Care to Older Patients With Cancer: A Qualitative Study

BACKGROUND

Older patients with cancer receive anticancer therapy in outpatient settings, and care-related issues may occur after discharge, which often requires family caregivers (FCs) to play a significant role in providing cancer care at home. However, relatively few studies have been focused on exploring the care experiences of these FCs.

PURPOSE

The aim of this study was to explore the care experiences of FCs caring for older family members with cancer at home.

METHODS

A qualitative study design and in-depth individual interviews were used to explore the at-home care experiences of FCs of older patients with cancer. The research was conducted in chemotherapy outpatient settings of a medical center in northern Taiwan. Content analysis was used to analyze data. The analyses focused on first extracting meaningful units from the text and then inducting categories from these units and determining the major themes.

RESULTS

Twenty FCs were interviewed. The three themes identified included (a) increased information needs and challenges in diet preparation and treatment decision making, (b) personal and patient-induced emotional stress, and (c) life rebalancing through the care experience.

CONCLUSIONS/IMPLICATIONS FOR PRACTICE

The findings highlight the educational requirements, especially related to meeting personal dietary needs and obtaining psychological support, for FCs caring for older patients with cancer to help them rebalance their life.

Bioimpedentiometry parameters used as indicators of frailty and malnutrition: association between G8 score and Phase angle (PHA) in elderly cancer patients

BACKGROUND

Since the incidence of cancer increases with age, in older cancer patients important information may be missed without a Comprehensive Geriatric Assessment (CGA). On the other side, CGA is a time-consuming and complex instrument, so that Geriatric 8 (G8) has been proposed as a more feasible screening tool to identify patients who could benefit from a CGA evaluation. G8 consists of 8 questions (patient age + 7 items derived from the Mini Nutritional Assessment questionnaire). A G8 score ≤ 14 is considered associated with frailty and risk of malnutrition. Another screening test is Bioelectrical Impedance Analysis (Bioimpedentiometry, BIA), which enables to evaluate the nutritional status through a specific parameter known as Phase angle (PhA). This study is aimed at assessing the ability of G8 alone or in combination with PhA to detect elderly cancer patients at higher risk for malnutrition who cannot undergo immediate anticancer treatments.

METHODS

A total of 289 cancer patients (168 men and 121 women) aged ≥ 70 years old were enrolled and performed both G8 test, body mass index (BMI) and BIA assessments. A concurrent G8 score ≤ 14 and PhA < 5 defined subjects most exposed to the risk of malnutrition.

RESULTS

An association between BMI and G8 (p < 0.001, OR 1.54) and a clinically significant relationship between G8 and PhA (p = 0.013) were observed.

CONCLUSION

G8 can be used to identify patients at risk for malnutrition who would benefit from comprehensive CGA. The concurrent use of G8 and BIA presents a higher power in discriminating subjects at higher risk of malnutrition than a single test. This study suggests the need for routine assessment of nutritional status in cancer patients using combinations of methods, in order to implement strategies for individually-tailored care before starting any treatment.

Hemoglobin, albumin, lymphocyte, and platelet (HALP) score and cancer prognosis: A systematic review and meta-analysis of 13,110 patients

BACKGROUND AND AIMS

We sought to explore the prognostic role of the hemoglobin, albumin, lymphocyte, and platelet (HALP) score on survival outcomes in patients with solid tumors by performing a systematic review and meta-analysis.

MATERIALS AND METHODS

PubMed, EMBASE and Web of Science were searched for relevant articles through 02 Nov 2022. Hazard ratios (HRs) with 95% confidence intervals (95% CIs) were extracted and pooled to assess the association of the HALP score with survival outcomes in solid tumors using Stata 15.0. The primary outcome was overall survival (OS), and the secondary outcomes were cancer-specific survival (CSS) and progression/disease/recurrence-free survival (PFS/DFS/RFS).

RESULTS

A total of 28 studies (31 cohorts) comprising 13,038 patients were enrolled. A low HALP score was associated with decreased OS (HR, 1.61; 95 % CI, 1.44-1.81; P < 0.001), CSS (HR, 1.80; 95 % CI: 1.54-2.09; P < 0.001) and PFS/DFS/RFS (HR, 1.61; 95 % CI: 1.45-1.80; P < 0.001). The prognostic value of HALP on OS was observed across various tumor types and tumor stages. meta-regression found that tumor stage was the major source of the heterogeneity for OS.

CONCLUSION

A low pretreatment HALP score is a reliable and negative prognostic biomarker for survival outcomes in patients with cancer.

A multinational investigation of healthcare needs, preferences, and expectations in supportive cancer care: co-creating the LifeChamps digital platform

Purpose

This study is to evaluate healthcare needs, preferences, and expectations in supportive cancer care as perceived by cancer survivors, family caregivers, and healthcare professionals.

Methods

Key stakeholders consisted of cancer survivors diagnosed with breast cancer, prostate cancer, or melanoma; adult family caregivers; and healthcare professionals involved in oncology. Recruitment was via several routes, and data were collected via either online surveys or telephone interviews in Greece, Spain, Sweden, and the UK. Framework analysis was applied to the dataset.

Results

One hundred and fifty-five stakeholders participated: 70 cancer survivors, 23 family caregivers, and 62 healthcare professionals (13 clinical roles). Cancer survivors and family caregivers’ needs included information and support on practical/daily living, as frustration was apparent with the lack of follow-up services. Healthcare professionals agreed on a multidisciplinary health service with a “focus on the patient” and availability closer to home. Most healthcare professionals acknowledged that patient-reported outcomes may provide “better individualised care”. Cancer survivors and family caregivers generally felt that the digital platform would be useful for timely personalised support and aided communication. Healthcare professionals were supportive of the “proactive” functionality of the platform and the expected advantages. Anticipated challenges were integration obstacles such as workload/infrastructure and training/support in using the new technology.

Conclusions

Obtaining key stakeholders’ insights provided a foundation for action to further co-create the LifeChamps digital platform to meet needs and priorities and deliver enhanced supportive care to “older” cancer survivors.

Implications for cancer survivors

Co-creation provided insight into gaps where digital support may enhance health and well-being.

Food for healthier aging: power on your plate

Inflammageing is a persistent low-level inflammatory burden that accompanies age-related dysregulation of the immune system during normative aging and within the diseasome of aging. A healthy diet containing a balanced amount of macronutrients, vitamins and minerals, adequate in calories and rich in poly(phenols), has an essential role in mitigating the effects of inflammageing and extending healthspan through modulation of the activity of a range of factors. These include transcription factors, such as nuclear factor erythroid-derived 2 related factor 2 (Nrf2) and nuclear factor-κB (NF-kB), the inflammasome and the activities of the gut microbiota. The aim of this narrative review is to discuss the potential of food to ameliorate the effects of the diseasome of aging.

Challenges in Geriatric Oncology—A Surgeon’s Perspective

As our global population ages, we will see more cancer diagnoses in older adults. Surgery is an important treatment modality for solid tumours, forming the majority of all cancers. However, the management of older adults with cancer can be more complex compared to their younger counterparts. This narrative review will outline the current challenges facing older adults with cancer and potential solutions. The challenges facing older adults with cancer are complex and include lack of high-level clinical trials targeting older adults and selection of the right patient for surgery. This may be standard surgical treatment, minimally invasive surgery or alternative therapies (no surgery) which can be local or systemic. The next challenge is to identify the individual patient’s vulnerabilities to allow them to be maximally optimised for treatment. Prehabilitation has been shown to be of benefit in some cancer settings but uniform guidance across all surgical specialties is required. Greater awareness of geriatric conditions amongst surgical oncologists and integration of geriatric assessment into a surgical clinic are potential solutions. Enhanced recovery programmes tailored to older adults could reduce postoperative functional decline. Ultimately, the greatest challenge an older adult with cancer may face is the mindset of their treating clinicians—a shared care approach between surgical oncologists and geriatricians is required.

A comprehensive overview of the complex relationship between epigenetics, bioactive components, cancer, and aging

Among age-related diseases, the incidence of cancer increases significantly due to the overlap of some molecular pathways between cancer and aging. While the genetic influence on the human lifespan is estimated to be about 20-25%, epigenetic changes play an important role in modulating individual health status, aging. Aging and age-related conditions are processes that can be modified by both genetic, environmental factors, including dietary habits. Epigenetics is a new discipline has significant potential to be applied for the prevention, management of certain carcinomas and diseases. Epigenetic modifications may play an important role in disease occurrence and pathogenesis. Some nutritional components can be significantly effective in the prevention of breast, skin, esophagus, colorectal, prostate, pancreatic, lung cancers. It contains minerals, vitamins, and some bioactive components (curcumin, indole 3 carbinol, di-indolylmethane, sulforaphane, epigallocatechin-3-gallate, genistein, resveratrol, pterostilbene, apigenin, etc.) regulatory processes. However, compelling evidence suggests that dietary habits can manipulate the aging process and/or its consequences, have health benefits. Aging processes become complex when combined with the relational role of bioactive nutritional components on gene expression. In this review, the relationship between epigenetic processes caused by DNA methylylation, histone modification, non-coding m-RNA, and telomerase activity, the risk of aging and cancer is discussed.
