Nutritional status in patients with advanced lung cancer undergoing chemotherapy: a prospective observational study

The Level of Adherence to the ESPEN Guidelines for Energy and Protein Intake Prospectively Influences Weight Loss and Nutritional Status in Patients with Cancer

Nutrition therapy aims to prevent weight loss and its health consequences in patients with cancer. The aim of this study was to assess Greek patients' adherence to the ESPEN guidelines for oncology patients and its prospective effect on their body weight (BW) and nutritional status. In total, 152 patients with cancer were recruited from the Attikon University Hospital, Greece, and provided data in 2019 (baseline) and 2020 (follow-up) (drop-out rate = 28.3%). Nutritional status was assessed with the PG-SGA questionnaire. Patients were categorized based on whether they adhered at least to the minimum ESPEN-recommended intakes of energy (≥25 kcal/kg/day) or protein (≥1.0 g/kg/day) or not. On average, patients did not adhere to ESPEN guidelines for energy and protein intake. Most patients meeting the minimum recommendations had an improvement of their nutritional status at follow-up and increased their BW compared to those not meeting them. All patients with head, neck, and spinal cancer who met the minimum recommendations for energy intake improved their nutritional status at follow-up. This study showed that consuming at least the minimum amounts of protein and energy recommended by ESPEN may prevent from weight loss and improve nutritional status; however, the exact amounts need to be personalized.

The Effect of Body Mass Index and Residence in Food Priority Areas on Patterns-of-Care and Cancer Outcomes in Patients With Stage III Non-Small Cell Lung Cancer

PURPOSE

Patients living in food priority areas (FPAs), where access to healthy meals is challenging, may be at greater risk of nutritional deficits, leading to poorer cancer outcomes. Currently, there are no published data analyzing how FPAs affect patterns-of-care or outcomes for patients with locally advanced non-small cell lung cancer (NSCLC). We aimed to analyze the effect of residing in an FPA on treatments rendered and cancer outcomes in patients with stage III NSCLC treated at a single institution.

METHODS AND MATERIALS

This is a retrospective study of 573 patients with locally advanced NSCLC consecutively treated from January 2000 to January 2020. χ² and Mann-Whitney U tests were performed to determine differences between select variables. Kaplan-Meier analysis and Cox proportional hazard models were used to analyze overall survival (OS) and freedom from recurrence. Cox regression with forward model selection was used for multivariate analysis.

RESULTS

Thirty-two percent of patients resided in an FPA (n = 183) and were more likely to self-identify as Black (P < .0001), single (P < .001), <60 years of age (P = .001), and uninsured (P < .0001), with a lower median income (P < .001). Patients in FPAs also had lower mean pre-chemoradiation (CRT) albumin (P = .002), lower pre-CRT body mass index (BMI) (P = .026), and were less likely to receive trimodality therapy (P ≤ .001) compared with patients not living in FPAs. There was no difference in OS or freedom from recurrence between the 2 cohorts. However, in patients with a normal BMI, either pre-CRT (median OS, 18.4 vs 25.0 months; P = .005) or after CRT (15.1 vs 28.1 months, P = .002), residing in an FPA resulted in an OS detriment.

CONCLUSIONS

We demonstrated a clear socioeconomic divide in our patient population with stage III NSCLC, where residing in FPAs was associated with less-aggressive therapy and an OS detriment for patients with a normal-weight BMI. We are currently conducting a prospective study characterizing the nutritional needs of patients, particularly those who live in FPAs.

Incidence and criteria used in the diagnosis of hospital-acquired malnutrition in adults: a systematic review and pooled incidence analysis

Despite advances in identifying malnutrition at hospital admission, decline in nutritional status of well-nourished patients can be overlooked. The aim of this systematic review was to investigate the incidence of hospital-acquired malnutrition (HAM), diagnostic criteria and health-related outcomes. PubMed, CINAHL, Embase and Cochrane Library were searched up to July 2021. Studies were included if changes in nutritional status was assessed with a validated nutrition assessment tool in acute and subacute adult (≥18 yrs) hospitalised patients. A random-effects method was used to pool the incidence proportion of HAM in prospective studies. The certainty of evidence was appraised using the Grading of Recommendation Assessment, Development and Evaluation system. We identified 12 observational cohort studies (10 prospective and 2 retrospective), involving 35,324 participants from acute (9 studies) and subacute settings (3 studies). Retrospective studies reported a lower incidence of HAM (<1.4%) than prospective studies (acute: 9-38%; subacute: 0-7%). The pooled incidence of HAM in acute care was 25.9% (95% confidence interval (CI): 17.3-34.6). Diagnostic criteria varied, with use of different nutrition assessment tools and timeframes for assessment (retrospective studies: >14 days; prospective studies: ≥7 days). Nutritional decline is probably associated with longer length of stay and higher 6-month readmission (moderate certainty of evidence) and may be association with higher complications and infections (low certainty of evidence). The higher incidence of HAM in the acute setting, where nutritional assessments are conducted prospectively, highlights the need for consensus regarding diagnostic criteria and further studies to understand the impact of HAM.

Prevalence of malnourishment and predictive factors associated with the nutritional status of gynecologic cancer patients undergoing chemotherapy: a cross-sectional analysis

Objective

To investigate the prevalence and predictive factors of malnourishment in patients with gynecologic cancer during chemotherapy.

Methods

A total of 101 patients treated with chemotherapy between April 2020 and February 2021 were interviewed using the patient-generated subjective global assessment (PG-SGA). Clinical and laboratory data were also collected. The total number of lymphocytes per cubic milliliter (total lymphocyte count, TLC) and serum albumin were calculated to provide an optimal cut-off point using receiver operating characteristic curves. Clinicopathological variables were compared using univariate and multivariate analyses to identify the independent predictive factors for malnourishment.

Results

The prevalence of good, moderate, and severe nourishment was 73.3%, 18.8%, and 7.9%, respectively. The optimal cut-off points for TLC and albumin were 1,450 cells/μL and for albumin was 3.9 g/dL. Univariate analysis indicated that the number of chemotherapy cycles ≤3, albumin level ≤3.95 g/dL, body mass index ≤25 kg/m², TLC <1,450 cells/μL, anemia, and no neutropenia were significantly associated with malnutrition. However, only a serum albumin level ≤3.95 g/dL was independently associated with malnourishment.

Conclusion

Patients with gynecologic cancer treated with chemotherapy were occasionally found to be malnourished, with the independent predictive predictor being a blood albumin level less than or equal to 3.95 g/dL.

Anti-inflammatory mouthwashes for the prevention of oral mucositis in cancer therapy: an integrative review and meta-analysis

PURPOSE

Mucositis is severely painful and often reported as one of the most distressing adverse effects of cancer therapy; it is a significant threat to quality of life as well as life itself. Anti-inflammatory agents may modulate physiologic mechanisms that perpetuate mucositis and be useful in prevention efforts. Because systemic anti-inflammatory agents are not appropriate for many patients, locally acting agents (mouthwashes) may be more feasible for use. This review and meta-analysis evaluates the role that anti-inflammatory mouthwashes have in preventing or reducing oral mucositis associated with chemotherapy and radiation therapy.

METHODS

A systematic literature review was conducted to identify studies evaluating the efficacy of anti-inflammatory mouthwashes to prevent therapy-associated mucositis. Meta-analysis was conducted to determine efficacy in preventing any mucositis and dose-limiting mucositis.

RESULTS

Eight peer-reviewed publications were identified; corticosteroid and nonsteroidal anti-inflammatory mouthwashes are effective in reducing overall incidence of mucositis and are associated with lower severity of mucositis. Meta-analysis reveals significant reduction in symptomatic mucositis incidence (OR 6.00, 95% CI 4.39-8.20, p < 0.0001) and reduction of dose-limiting mucositis (OR 2.12, 95% CI 1.07-4.28, p = 0.032).

CONCLUSION

Mouthwashes containing anti-inflammatory agents are a potential effective means to prevent or reduce mucositis associated with cancer therapy. There are limited adverse effects from these agents, and adherence is high, indicating safety and feasibility of use. Anti-inflammatory mouthwashes should be considered for supportive care in persons at risk for mucositis and must be further evaluated to investigate efficacy across multiple chemotherapy agents, adverse effects, and impacts on symptoms, pain, and quality of life.

Patients with cancer experience high impact of emotional consequences of reduced ability to eat: A cross sectional survey study

OBJECTIVE

Patients with cancer can experience emotional consequences of reduced ability to eat, their impact is unknown. This study assesses the impact of these emotional consequences, and patients' satisfaction with healthcare professionals' (HCPs) support.

METHODS

A cross-sectional survey was conducted among patients with head/neck, lung cancer and lymphoma, who experienced reduced ability to eat in the past year. Patients were recruited through patient organisations and hospitals. The questionnaire encompassed the impact of emotional consequences of reduced ability to eat (scale 1-10) and satisfaction with HCPs' support for reduced ability to eat (scale 1-10). The differences in patient characteristics between unsatisfied (Score < 6) and satisfied patients (score ≥6) were tested using independent t-tests and the chi-square or Fishers' exact tests.

RESULTS

Overall, 116 patients (48%) responded and 98 were included in the analyses. The most impactful emotional consequences were as follows: disappointment (mean ± SD: 8.31 ± 1.49), grief/sadness (7.90 ± 1.91), and anger (7.87 ± 1.41). Patients were less satisfied when more time had passed since their diagnosis (p < 0.002) and when they expected no improvements regarding their eating problems (p < 0.001).

CONCLUSION

The impact of emotional consequences of reduced ability to eat is high. Support for emotional consequences is needed, especially for patients with reduced ability to eat, which persists in recovery and remission.

Omega-3 Fatty Acids Supplementation Improve Nutritional Status and Inflammatory Response in Patients With Lung Cancer: A Randomized Clinical Trial

Background and Aims: Clinical studies have reported positive results with omega-3 supplements in patients with cancer. This study aimed to evaluate the efficacy of omega-3 fatty acid supplementation in improving the nutritional status and inflammatory markers of patients with lung cancer.

Methods: In a randomized, double-blind, parallel design trial, 60 patients with lung cancer at nutritional status/risk based on the Nutrition Risk Screening 2002 were randomized to be allocated to two study groups, receiving omega-3 fatty acid supplements [eicosapentaenoic acid (EPA) 1.6 g and docosahexaenoic acid (DHA) 0.8 g] or placebo for 12 weeks. Anthropometric measurements [weight, body mass index (BMI), the circumference of the upper arm, and skinfold thickness of triceps], nutrition-based laboratory indices (hemoglobin, albumin, triglyceride, and cholesterol), and inflammatory markers [C-reactive protein (CRP), tumor necrosis factor alpha (TNF-α), and interleukin 6 (IL-6)] were measured before and after the intervention as study outcomes.

Results: No significant difference between the two study groups was observed regarding basic characteristics and study outcomes. Compared with placebo group, omega-3 fatty acid supplementation group showed significant higher weight (66.71 ± 9.17 vs. 61.33 ± 8.03, p = 0.021), albumin (4.74 ± 0.80 vs. 4.21 ± 0.77, p = 0.013), and triglyceride (130.90 ± 25.17 vs. 119.07 ± 14.44, p = 0.032). Inflammatory markers were significantly reduced in omega-3 group compared to placebo (CRP 1.42 ± 0.63 vs. 3.00 ± 1.05, p = 0.001 and TNF-α 1.92 ± 0.65 vs. 4.24 ± 1.19, p = 0.001). No significant difference was observed between the two study groups regarding changes in BMI, the circumference of the upper arm, skinfold thickness of triceps, triglyceride, cholesterol, and IL-6 (p > 0.05).

Conclusions: Omega-3 fatty acid supplementation can improve nutritional status and suppress the systemic inflammatory response in patients with lung cancer.

Nutritional support during the hospital stay reduces mortality in patients with different types of cancers: secondary analysis of a prospective randomized trial

BACKGROUND

Nutritional support in patients with cancer aims at improving quality of life. Whether use of nutritional support is also effective in improving clinical outcomes requires further study.

PATIENTS AND METHODS

In this preplanned secondary analysis of patients with cancer included in a prospective, randomized-controlled, Swiss, multicenter trial (EFFORT), we compared protocol-guided individualized nutritional support (intervention group) to standard hospital food (control group) regarding mortality at 30-day (primary endpoint) and other clinical outcomes.

RESULTS

We analyzed 506 patients with a main admission diagnosis of cancer, including lung cancer (n = 113), gastrointestinal tumors (n = 84), hematological malignancies (n = 108) and other types of cancer (n = 201). Nutritional risk based on Nutritional Risk Screening (NRS 2002) was an independent predictor for mortality over 180 days with an (age-, sex-, center-, type of cancer-, tumor activity- and treatment-) adjusted hazard ratio of 1.29 (95% CI 1.09-1.54; P = 0.004) per point increase in NRS. In the 30-day follow-up period, 50 patients (19.9%) died in the control group compared to 36 (14.1%) in the intervention group resulting in an adjusted odds ratio of 0.57 (95% CI 0.35-0.94; P = 0.027). Interaction tests did not show significant differences in mortality across the cancer type subgroups. Nutritional support also significantly improved functional outcomes and quality of life measures.

CONCLUSIONS

Compared to usual hospital nutrition without nutrition support, individualized nutritional support reduced the risk of mortality and improved functional and quality of life outcomes in cancer patients with increased nutritional risk. These data further support the inclusion of nutritional care in cancer management guidelines.

Experiences of patients with cancer with information and support for psychosocial consequences of reduced ability to eat: a qualitative interview study

PURPOSE

Patients with cancer may experience emotions such as anger or sadness due to tumour- or treatment-related reduced ability to eat. These emotions can be provoked by patients' own struggle with eating, by misunderstanding of their struggle by others, or by less pleasure in social activities. Literature indicates that patients with cancer may experience a lack of information and support regarding psychosocial consequences of reduced ability to eat. The aim of this qualitative study is to gain insights into experiences with this information and support.

METHOD

Transcripts of semi-structured interviews with 24 patients with cancer who experience(d) psychosocial consequences of reduced ability to eat were thematically analysed. Interviews were recorded, transcribed verbatim, and analysed using Atlas.ti.

RESULTS

Patients expressed positive experiences with information and support for psychosocial consequences of reduced ability to eat while receiving multidisciplinary recognition and personalised care. Patients expressed negative experiences when healthcare professionals only assessed topics within their own expertise, or when healthcare professionals mainly focused on their nutritional intake. Informal support for reduced ability to eat was positively evaluated when informal caregivers tried to understand their situation. Evaluation of informal practical support varied among patients.

CONCLUSION

Patients with cancer who experience psychosocial consequences of reduced ability to eat both need professional and informal support. Recognition of these consequences from healthcare professionals is important, as well as understanding from informal caregivers.

The Clinical Value of Nutritional Care before and during Active Cancer Treatment

Malnutrition and muscle wasting are frequently reported in cancer patients, either linked to the tumor itself or caused by oncologic therapies. Understanding the value of nutritional care during cancer treatment remains crucial. In fact, cancer-associated sarcopenia plays a key role in determining higher rates of morbidity, mortality, treatment-induced toxicities, prolonged hospitalizations and reduced adherence to anticancer treatment, worsening quality of life and survival. Planning baseline screening to intercept nutritional troubles earlier, organizing timely reassessments, and providing adequate counselling and dietary support, healthcare professional may positively interfere with this process and improve patients' overall outcomes during the whole disease course. Several screening tools have been proposed for this purpose. Nutritional Risk Screening (NRS), Mini Nutritional Assessment (MNA), Patient Generated Subjective Global Assessment (PG-SGA) are the most common studied. Interestingly, second-level tools including skeletal muscle index (SMI) and bioelectric impedance analysis (BIA) provide a more precise assessment of body composition, even if they are more complex. However, nutritional assessment is not currently used in clinical practice and procedures must be standardized in order to improve the efficacy of standard chemotherapy, targeted agents or even checkpoint inhibitors that is potentially linked with the patients' nutritional status. In the present review, we will discuss about malnutrition and the importance of an early nutritional assessment during chemotherapy and treatment with novel checkpoint inhibitors, in order to prevent treatment-induced toxicities and to improve survival outcomes.

Red Raspberry Extracts Inhibit A549 Lung Cancer Cell Migration, Invasion, and Epithelial-Mesenchymal Transition Through the Epidermal Growth Factor Receptor/Signal Transducer and Activator of Transcription-3 Signaling Pathway

The incidence and mortality of lung cancer ranks first among all malignant tumors in the world. Because it is relatively asymptomatic at early stages, most patients do not become aware of the disease until it has progressed to an advanced stage. Advanced lung cancer metastasis results in systemic cachexia and effective treatment becomes challenging, leading to poor response and outcome. Therefore, the development of new drugs for the treatment of lung cancer is paramount. In this study, A549 cells were treated with different concentrations of red raspberry extract and the proliferation, migration, and invasion of cells were evaluated. The results indicated that red raspberry extract reduced the proliferation, migration, and invasion of A549 cells. Western blot analysis was used to detect the expression of the cyclin D1, N-cadherin, vimentin, E-cadherin, EGFR, and STAT3 proteins. Treatment with red raspberry extract reduced the expression of cyclin D1, N-cadherin, vimentin, EGFR, and STAT3, whereas the expression of E-cadherin increased. Following transfection of an EGFR overexpression vector into A549 cells, we observed a reduced inhibitory effect of the red raspberry extract on the proliferation, migration, and invasion of A549 cells. In addition, EGFR overexpression abrogated the increased expression of cyclin D1, N-cadherin, vimentin, EGFR, and STAT3 protein expression in A549 cells following extract treatment. In contrast, E-cadherin protein expression was decreased under these treatment conditions. Overall, this study suggests that red raspberry extract may reduce the proliferation, migration, invasion, and epithelialmesenchymal transition of A549 lung cancer cells by inhibiting the activation of the EGFR/STAT3 signaling pathway. These findings may lead to the development of new strategies to treat advanced lung cancer.

Nutritional Support in Lung Cancer Patients: The State of the Art

Lung cancer (LC) represents the most commonly diagnosed neoplasm worldwide for both sexes and is the leading cause of cancer mortality. Malnutrition is a comorbidity frequently found in neoplastic patients, but it remains often underestimated and thus undertreated. In this review, we aimed to investigate the incidence of malnutrition among LC patients according to different screening and assessment tools, to evaluate the impact of weight loss and body composition on survival, and to analyze the efficacy of different nutritional interventions in this setting. Although malnutrition, weight loss, and body composition changes can affect survival and other clinical outcomes in LC patients, the role of nutritional interventions is not yet strongly proven, and further studies are recommended. Nevertheless, screening, assessing, and eventually treating malnutrition in LC patients are strongly recommended, according to the most recent nutritional intervention guidelines for oncology patients.

Nutrition in Cancer: Evidence and Equality

PURPOSE

Poor nutrition is highly implicated in the pathogenesis of cancer and affects the survival of patients during and after completion of definitive therapies. Mechanistic evidence accumulated over the last century now firmly places dysregulated cellular energetics within the emerging hallmarks of cancer. Nutritional intervention studies often aim to either enhance treatment effect or treat nutritional deficiencies that portend poor prognoses. Patients living within food priority areas have a high risk of nutritional need and are more likely to develop comorbidities, including diabetes, hypertension, renal disease, and cardiovascular risk factors. Unfortunately, there is currently a paucity of data analyzing the impact of food priority areas on cancer outcomes.

METHODS

Therefore, we performed a review of the literature focusing on the molecular and clinical interplay of cancer and nutrition, the importance of clinical trials in elucidating how to intervene in this setting and the significance of including citizens who live in food priority areas in these future prospective studies.

CONCLUSIONS

Given the importance of nutrition as an emerging hallmark of cancer, further research must be aimed at directing the optimal nutrition strategy throughout oncologic treatments, including the supplementation of nutritious foods to those that are otherwise unable to attain them.
