The effect of individualized nutritional counseling on muscle mass and treatment outcome in patients with metastatic colorectal cancer undergoing chemotherapy: a randomized controlled trial protocol.

ABSTRACT: A low muscle mass is prevalent in patients with metastatic colorectal cancer (mCRC) and has been associated with poor treatment outcome. Chemotherapeutic treatment has an additional unfavorable effect on muscle mass. Sufficient protein intake and physical activity are known to induce muscle protein anabolism in healthy individuals, however it is unclear whether optimal nutrition is effective to preserve muscle mass in patients with mCRC during first-line chemotherapy as well. We hypothesize that individual nutritional counseling by a trained dietitian during first-line chemotherapy is effective in preserving muscle mass and may improve clinical outcomes in patients with mCRC.In this multi-center single-blind randomized controlled trial, patients with mCRC scheduled for first-line combination chemotherapy consisting of oxaliplatin and fluoropyrimidine, with or without bevacizumab (n?=?110), will be randomized to receive either individualized nutritional counseling by a trained dietitian to achieve a sufficient dietary intake and an adequate physical activity level, or usual care. Outcome measures will be assessed at baseline and after two and four months of treatment. The primary endpoint will be the change in skeletal muscle area (measured by CT-scan) at the first treatment evaluation. Secondary endpoints will be quality of life, physical functioning, treatment toxicity, treatment intensity and survival. Statistical analyses include one-sided t-tests for the primary endpoint and mixed models and the Kaplan-Meier method for secondary endpoints.This randomized controlled trial will provide evidence whether individualized nutritional counseling during chemotherapy is effective in preventing loss of muscle mass in patients with mCRC.ClinicalTrials.gov NCT01998152 ; Netherlands Trial Register NTR4223.

Project description:BackgroundStudies over the past 10 years strongly support an association between skeletal muscle mass (SMM) depletion and outcome in metastatic colorectal cancer (mCRC). Factors influencing SMM changes over time are, however, poorly studied. We analyzed the impact of SMM on overall survival and chemotherapy toxicities in mCRC patients treated with first-line chemotherapy. Changes in weight and body composition were evaluated during follow-up.MethodsPatients enrolled in the randomized phase II ACCORD trial comparing two chemotherapy regimens were screened. Body composition parameters (SMM, adipose tissue) were assessed prospectively with computed tomography (CT) imaging, and toxicities were recorded. Mixed models were used to assess weight and BC changes during 4 months of treatment follow-up.ResultsAmong 145 patients included in ACCORD, 76 had available baseline CT scans and were included in the current study. Mean age was 60.6 ± 10.0 years, 50% were women, 82% had colon cancer, and 62% had two or more metastatic sites. At baseline, 49% had lost at least 5% of their initial weight, including 26% who had lost more than 10%; 53% had SMM depletion. In this homogenous cohort, there were no statistically significant associations between SMM depletion and overall survival, progression-free survival or chemotherapy toxicity. There were no decreases in weight or SMM during follow-up. Weight and SMM changes were not influenced by diarrhea either grade 3-4 or any grade (reported in 74% of patients). For patients with weight loss ≥10% at baseline, SMM increased significantly after 4 months of follow-up and after disease stabilization following chemotherapy (P = 0.008).ConclusionsIn a homogenous mCRC cohort, SMM depletion was not associated with survival or chemotherapy toxicity. Despite most patient experiencing diarrhea, no changes in weight or SMM were found during 4 months of follow-up. However, hypotheses deriving from our exploratory study have to be tested in further larger sample size studies.Trial registrationClinicaltrials.gov NCT00423696 (2011).

Project description:BACKGROUND:Increasing evidence suggests that severe skeletal muscle index (SMI) loss (sarcopenia) is associated with poor overall survival in metastatic colorectal cancer patients, but its mechanisms are unknown. We recently found, using data of the randomized phase 3 CAIRO3 study, that SMI loss was related with shorter time to disease progression and overall survival during first-line maintenance treatment with capecitabine + bevacizumab (CAP-B) or observation and during more intensive capecitabine + oxaliplatin + bevacizumab (CAPOX-B) reintroduction treatment. As a potential risk factor for reduced survival, we explored whether sarcopenia and SMI loss were associated with dose-limiting toxicities (DLTs) during CAP-B and CAPOX-B. METHODS:Sarcopenia status and SMI loss were assessed by using consecutive computed tomography scans. DLTs were defined as any dose delay/reduction/discontinuation of systemic treatment because of reported CTCAE (version 3.0) toxicities at the start or during treatment. Poisson regression models were used to study whether sarcopenia and body mass index (BMI) at the start of treatment and SMI and BMI loss during treatment were associated with DLTs. RESULTS:One hundred eighty-two patients (mean age 63.0 ± 8.8 years, 37% female) received CAP-B, and 232 patients (mean age 63.0 ± 9.0 years, 34% female) received CAPOX-B. At the start of CAP-B and CAPOX-B, 54% and 46% of patients were sarcopenic, respectively. Mean BMI was lower in sarcopenic patients, although patients were on average still overweight (sarcopenic vs. non-sarcopenic at the start of CAP-B 25.0 ± 3.9 vs. 26.7 ± 4.1 and CAPOX-B 25.8 ± 3.8 vs. 27.1 ± 3.8 kg/m2 ). Sarcopenia at the start of CAP-B was not associated with DLTs [relative risk 0.87 (95% confidence interval 0.64-1.19)], whereas patients with >2% SMI loss had a significantly higher risk of DLTs [1.29 (1.01-1.66)]. At the start of subsequent CAPOX-B, 25% of patients received a dose reduction, and the risk of dose reduction was significantly higher for patients with preceding SMI loss [1.78 (1.06-3.01)] or sarcopenia [1.75 (1.08-2.86)]. After the received dose reductions, sarcopenia or SMI loss was not significantly associated with a higher risk of DLTs during CAPOX-B [sarcopenia vs. non-sarcopenic: 0.86 (0.69-1.08) and SMI loss vs. stable/gain: 0.83 (0.65-1.07)]. In contrast, BMI (loss) at the start or during either treatment was not associated with an increased risk of DLTs. CONCLUSIONS:In this large longitudinal study in metastatic colorectal cancer patients during palliative systemic treatment, sarcopenia and/or muscle loss was associated with an increased risk of DLTs. BMI was not associated with DLTs and could not detect sarcopenia or SMI loss. Prospective (randomized) studies should reveal whether normalizing chemotherapeutic doses to muscle mass or muscle mass preservation (by exercise and nutritional interventions) increases chemotherapeutic tolerance and improves survival.

Project description:Background: Locally advanced head and neck cancer is managed either by combined surgery and (chemo) radiotherapy or definitive (chemo) radiotherapy, which may deteriorate nutritional status. Previous data have shown that intensive nutritional intervention by a dietician reduces radiation-induced adverse events including weight loss. Objective: To determine if on-demand nutritional counseling (ODC, control group) would be as efficacious as intensive nutritional counseling (INC, experimental group) in patients undergoing (chemo) radiotherapy. Methods: Fifty-eight patients were randomly assigned to receive INC (n = 26) or ODC (n = 32). Outcome measures were nutritional status (PG-SGA), weight loss, handgrip strength (HGS), body composition, and survival. Results: Weight loss and impaired nutritional parameters during oncological treatment were seen equally in both groups (NS). Leaner patients at baseline maintained their weight, while overweight patients lost both weight and handgrip strength during treatment. Disease-free survival (DFS) (median = 43 months) was not affected by weight loss during treatment. Lower baseline HGS and malnutrition were associated with worse DFS (low vs. normal HGS: 15 vs. 42 months; p = 0.05 and malnutrition vs. good nutrition status: 17 vs. 42 months; p = 0.014, respectively). Survival according to low vs. normal HGS in the INC group was 4 vs. 44 months (p = 0.007) and in the ODC group 28 vs. 40 months (p = 0.944). According to malnutrition vs. good nutritional status in the INC group, DFS was 21 vs. 43 months (p = 0.025) and in the ODC group 15 vs. 41 months (p = 0.03). Conclusions: As for our primary endpoint, individualized on-demand nutritional counseling was as efficacious as intensive counseling in preventing deterioration of nutritional status and incidence of malnutrition during (chemo) radiotherapy. This should be verified with larger number of patients. Additional findings were that overweight patients had more severe weight loss, but not poorer survival. Low HGS and malnutrition at baseline were associated with poor survival. Clinical Trial Registration: www.ClinicalTrials.gov, identifier NCT02159508.

Project description:Evidence from randomized controlled trials shows that exercise during cancer treatment benefits physical fitness, fatigue and quality of life. Since the effect of exercise on clinical outcome is currently unknown, exercise is not included as integral part of standard cancer care. Moreover, evidence regarding the optimal exercise prescription in terms of type and dose is lacking. To maintain quality of life in patients receiving palliative treatment with chemotherapy, toxicity-induced modifications in the prescribed chemotherapy dose are common. Such modifications - occurring in 40% of patients with metastatic colorectal cancer - may reduce benefit of treatment. The investigators hypothesize that exercise prevents chemotherapy dose modifications by reducing toxicity and enhancing psychological strength. Additionally, based on studies in rodents and preliminary data in patients with cancer, the researchers hypothesize that exercise has beneficial effects on the functionality of the natural killer cells, which play an important role in the innate immune defense against cancer. Both, fewer dose modifications and improved immune function may improve progression-free survival. This study is a three-armed trial comparing resistance exercise, aerobic interval exercise and usual care in patients with metastatic colorectal cancer to select the optimal exercise prescription for preventing chemotherapy dose modifications. The trial will use a Bayesian adaptive multi-arm multi-stage design with several interim analyses after which an ineffective study arm can be dropped early. This novel design makes the trial more efficient and reduces patients’ exposure to suboptimal study arms. Evidence regarding the exercise effects on i) clinical outcome, ii) the optimal exercise prescription, and iii) the underlying mechanisms, elucidates the potential of exercise to boost benefit from chemotherapy treatment. This evidence provides leads to improve progression-free survival and quality of life of patients suffering from one of the leading causes of cancer death worldwide.

Project description:BACKGROUND:Observational studies suggest that loss of skeletal muscle mass (SMM) is associated with chemotherapy-related toxicity, poor quality of life, and poor survival in metastatic colorectal cancer (mCRC) patients. Little is known about the evolution of SMM during palliative systemic therapy. We investigated changes in SMM during various consecutive palliative systemic treatment regimens using repeated abdominal computed tomography scans of mCRC patients who participated in the randomized phase 3 CAIRO3 study. METHODS:In the CAIRO3 study, mCRC patients with stable disease or better after 6 cycles of first-line treatment with capecitabine + oxaliplatin + bevacizumab (CAPOX-B) were randomized between maintenance treatment with capecitabine + bevacizumab (CAP-B) or observation. Upon first disease progression, in both groups, CAPOX-B or other treatment was reintroduced until the second disease progression, which was the primary study endpoint. We analysed 1355 computed tomography scans of 450 (81%) CAIRO3 patients (64 ± 9.0 years, CAP-B n = 223; observation n = 227) for SMM at four time points (i.e. prior to the start of pre-randomization initial treatment, at randomization, and at first and at second disease progression) using the Slice-o-matic software and single slice evaluation at the lumbar 3 level. By using accepted and widely used formulas, whole body SMM was calculated. A linear mixed effects model, adjusted for relevant confounders, was used to assess SMM changes for the total group and within and between study arms. RESULTS:During 6 cycles of initial treatment with CAPOX-B prior to randomization, SMM decreased significantly in all patients [CAP-B arm: -0.53 kg (95% CI -1.12; -0.07) and observation arm: -0.85 kg (-1.45; -0.25)]. After randomization, SMM recovered during CAP-B treatment by 1.32 kg (0.73; 1.90) and observation by 1.20 kg (0.63; 1.78) (median time from randomization to first disease progression 8.6 and 4.1 months for CAP-B arm and observation arm, respectively). After first progression and during reintroduction treatment with CAPOX-B or other treatment, SMM again decreased significantly and comparable in both arms, CAP-B: -2.71 kg (-3.37; -2.03), and observation: -2.01 kg (-2.64; -1.41) (median time from first progression until second progression CAP-B arm: 4.7 months and observation arm: 6.6 months). CONCLUSIONS:This longitudinal study provides a unique insight in SMM changes in mCRC patients during palliative systemic treatment regimens, including observation. Our data show that muscle loss is reversible and may be influenced by the intensity of systemic regimens. Although studies have shown prognostic capacity for SMM, the effects of subsequent changes in SMM are unknown and may be clues for new future therapeutic interventions.

Project description:Background:Malnutrition is common in cancer patients, particularly in those affected by gastrointestinal malignancies, and negatively affects treatment tolerance, survival, functional status, and quality of life (QoL). Nutritional support, including supplemental parenteral nutrition (SPN), has been recommended at the earliest opportunity in malnourished cancer patients. The limited available evidence on the efficacy of SPN in gastrointestinal cancer patients is positive, particularly with regards to QoL, body composition, and energy intake, but the evidence on survival is still scanty. Furthermore, studies regarding the early administration of SPN in combination with nutritional counseling from the beginning of first-line chemotherapy (CT) are lacking. We hypothesize that early systematic SPN in combination with nutritional counseling (NC), compared with NC alone, can benefit patients with previously untreated metastatic gastric cancer at nutritional risk undergoing first-line CT. Methods:The aim of this pragmatic, multicenter, randomized (1:1), parallel-group, open-label, controlled clinical trial is to evaluate the efficacy in terms of survival, weight maintenance, body composition, QoL and feasibility of cancer therapy of early systematic SNP. This is in combination with NC, compared with NC alone, in treatment-naïve metastatic gastric cancer patients at nutritional risk undergoing first-line CT. Discussion:Malnutrition in oncology remains an overlooked problem. Although the importance of SPN in gastrointestinal cancer patients has been acknowledged, no studies have yet evaluated the efficacy of early SPN in metastatic gastric patients undergoing CT. The present study, which guarantees the early provision of nutritional assessment and support to all the enrolled patients in accordance with the recent guidelines and recommendations, could represent one of the first proofs of the clinical effectiveness of early intensive nutritional support in cancer patients undergoing CT. This study could stimulate further large randomized trials in different cancer types, potentially resulting in the improvement of supportive care quality. Trial registration:This study is registered on ClinicalTrials.gov: NCT03949907.
