Role of nutritional status and intervention in oesophageal cancer treated with definitive chemoradiotherapy: outcomes from SCOPE1.

ABSTRACT:

Background

Malnutrition is common in oesophageal cancer. We aimed to identify nutritional prognostic factors and survival outcomes associated with nutritional intervention in the SCOPE1 (Study of Chemoradiotherapy in OesoPhageal Cancer with or without Erbitux) trial.

Methods

Two hundred and fifty eight patients were randomly allocated to definitive chemoradiotherapy (dCRT) +/- cetuximab. Nutritional Risk Index (NRI) scores were calculated; NRI<100 identified patients at risk of malnutrition. Nutritional intervention included dietary advice, oral supplementation or major intervention (enteral feeding/tube placement). Univariable and multivariable analyses using Cox proportional hazard modelling were conducted.

Results

At baseline NRI<100 strongly predicted for reduced overall survival (hazard ratio (HR) 12.45, 95% CI 5.24-29.57; P<0.001). Nutritional intervention improved survival if provided at baseline (dietary advice (HR 0.12, P=0.004), oral supplementation (HR 0.13, P<0.001) or major intervention (HR 0.13, P=0.003)), but not if provided later in the treatment course. Cetuximab patients receiving major nutritional intervention had worse outcomes compared with controls (13 vs 28 months, P=0.003).

Conclusions

Pre-treatment assessment and correction of malnutrition may improve survival outcomes in oesophageal cancer patients treated with dCRT. Nutritional Risk Index is a simple and objective screening tool to identify patients at risk of malnutrition.

Project description:BACKGROUND:Limited data describe patient-reported outcomes (PROs) of localised oesophageal cancer treated with definitive chemoradiotherapy(CRT). The phase 2/3 SCOPE-1 trial assessed the effectiveness of CRT±cetuximab. The trial for the first time provided an opportunity to describe PROs from a multi-centre group of patients treated with CRT that are presented here. METHODS:Patients undergoing CRT±cetuximab within the SCOPE-1 trial (258 patients from 36 UK centres) completed generic-, disease- and treatment-specific health-related quality of life (HRQL) questionnaires (EORTC QLQ-C30, QLQ-OES18, Dermatology Life-Quality Index (DLQI)) at baseline and at 7, 13, 24, 52 and 104 weeks. Mean EORTC functional scale scores (>15 point change significant), DLQI scores (>4 point change significant) and proportions of patients (>15% significant) with 'minimal' or 'severe' symptoms are presented. RESULTS:Questionnaire response rates were good. At baseline, EORTC functional scores were high (>75%) and few symptoms were reported except for severe problems with fatigue, insomnia and eating-related symptoms (e.g., appetite loss, dysphagia, dry mouth) in both groups(>15%). Functional aspects of health deteriorated and symptoms increased with treatment and by week 13 global quality of life, physical, role and social function significantly deteriorated and more problems with fatigue, dyspnoea, appetite loss and trouble with taste were reported. Recovery occurred by 6 months (except severe fatigue and insomnia in >15% of patients) and maintained at follow-up with no differences between groups. CONCLUSIONS:CRT for localised oesophageal cancer has a significant detrimental impact on many aspects of HRQL; however, recovery is achieved by 6 months and maintained with the exception of persisting problems with severe fatigue and insomnia. The data suggest that the HRQL recovery after definitive CRT is quicker, and there is little lasting deficit compared with treatment including surgery. These data need to be compared with HRQL data from studies evaluating treatments including surgery for oesophageal cancer.

Project description:BackgroundThis study aimed to evaluate the predictive potential of contrast-enhanced computed tomography (CT)-based imaging biomarkers (IBMs) for the treatment outcomes of patients with oesophageal squamous cell carcinoma (OSCC) after definitive concurrent chemoradiotherapy (CCRT).MethodsAltogether, 154 patients with OSCC who underwent definitive CCRT were included in this retrospective study. All patients were randomised to the training cohort (n?=?99) or the validation cohort (n?=?55). Pre-treatment contrast-enhanced CT scans were obtained for all patients and used for the extraction of IBMs. An IBM score, was constructed by using the least absolute shrinkage and selection operator with Cox regression analysis, which was equal to the log-partial hazard of the Cox model in the training cohort and tested in the validation cohort. IBM nomograms were built based on IBM scores for individualised survival estimation. Finally, a decision curve analysis was performed to estimate the clinical usefulness of the nomograms.ResultsAltogether, 96 IBMs were extracted from each contrast-enhanced CT scan. IBM scores were constructed from 11 CT-based IBMs for overall survival (OS) and 8 IBMs for progression-free survival (PFS), using the LASSO-Cox regression method in the training cohort. Multivariate analysis revealed that IBM score was an independent prognostic factor correlated with OS and PFS. In the training cohort, the C-indices of IBM scores were 0.734 (95% CI 0.664-0.804) and 0.658 (95% CI 0.587-0.729) for OS and PFS, respectively. In the validation cohort, C-indices were 0.672 (95% CI 0.578-0.766) and 0.666 (95% CI 0.574-0.758) for OS and PFS, respectively. Kaplan-Meier survival analysis showed a significant difference between risk subgroups in the training and validation cohorts. Decision curve analysis confirmed the clinical usefulness of the IBM score.ConclusionsThe IBM score based on pre-treatment contrast-enhanced CT could predict the OS and PFS for patients with OSCC after definitive CCRT. Further multicentre studies with larger sample sizes are warranted.
