Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
All participants will receive chemotherapy consisting of carboplatin (AUC=2) and paclitaxel (50mg/m2)administered intravenously one day per week for 5 weeks. At the same time, radiotherapy will be given with a total dose of 41.4 Gy in 23 fractions, starting on the first day of the first chemotherapy cycle with 5 fractions per week over 4.5 weeks. PET scan will be performed 4 weeks after chemoradiation. Patients will be fasted for 4 hours before imaging and blood glucose level will be measured. Patients will be injected with a small amount of radioactive tracer fluorodeoxygluocose (FDG) and the PET scan will take place for about 45-90 minutes. Patients will undergo surgery 6 weeks after chemoradiation.

Outcomes
Primary outcome [1] 292382 0
To assess the predictive value of the post chemoradiation PET scan with pathological response after surgical resection (volumetric PET assessment)

PET scan is performed at week 9 (4 weeks post chemoradiation) and the sensitivity, specificity, positive and negative predictive values of PET will be calculated. Whilst PET data is the primary analysis, pathological assessment obtained from surgery at week 11 (6 weeks post chemoradiation) is used to examine the correlation of PET and pathological response.

Type of endpoint/s
Statistical methods / analysis
Survival endpoints were calculated from the date of enrolment. OS and DFS were estimated using the Kaplan-Meier product limit method and will be displayed using Kaplan-Meier curves and median survivals

The level of significance of a series of prognostic factors in the prediction of survival endpoints was estimated using the log-rank test statistic. Cox regression analysis provided a multivariate analysis of these endpoints with selected prognostic factors

Continuous variables will be summarized using descriptive statistics e.g. number of patients, mean, median, standard deviation, minimum and maximum. Qualitative variables will be summarized by counts and percentages. Unless otherwise stated calculation of proportions will include the missing category. Longitudinal data will be illustrated where appropriate with graphics

Descriptive statistics of baseline patient characteristics and treatment received will be presented for all eligible patients

EORTC QLQ will be described according to EORTC guidelines. A descriptive analysis of Quality of Life (QoL) data over time will be undertaken. This will include identifying the most commonly reported, and the most troublesome, symptoms and side effects. Items from the questionnaires will be derived to form numerical scales in accordance with the scoring manuals and/or scoring conventions for each instrument. The applicability of repeated measures mixed modelling to the QoL scores collected longitudinally will be investigated. Appropriate methods for dealing with missing QoL data will be detailed in the statistical analysis plan and be informed by a blinded review of the data. Under certain assumptions, mixed models provide unbiased estimates as do multiple imputation techniques. Patterns of missing data will be considered to assess potential missing data mechanisms

A descriptive analysis of the adverse events (AE) data will be prepared for study participants. The number and percentage of participants who experience AEs will be tabulated according to AE name, organ class and grade. The number and percentage of participants who experience a grade 3 or 4 AE will also be tabulated, as will the number and percentage of participants who experience any grade AE. A descriptive analysis of dose interruption and dose modification rates will also be prepared

The 95% confidence intervals will be reported wherever appropriate

A study close-out date will be determined for the time to event analyses in order to prevent bias in the reporting of results. This is generally taken to be the earliest of the dates of last contact for patients still alive and not lost to follow-up. The event times of patients lost to follow up will be censored at the close-out date if the event has not previously occurred

Statistical analyses will be performed using STATA-SE v.11.0 (StataCorp LP, College Station, TX, USA)

A samples size of at least 184 patiens will be sufficient to exclude a false negative rate of 5% or higher (lower 95% for totaol concordance >0.95). Allowing for a modest number of drop outs and patients not proceeding to surgery, a total of 200 patients will be recruited.

Summary
Brief summary
This phase II study aims to investigate whether PET scan performed after the completion of chemotherapy and radiation can predict response of oesophageal cancer.
Who is it for ? You may be eligible to join this study if you are aged 18 years or more, have been diagnosed with a localised oesophageal cancer, and are suitable for chemotherapy combined with radiotherapy prior to surgery.
Study details: Participants will undergo a single additional PET scan 4 weeks after the completion of chemo-radiotherapy. Approximately 2 weeks following this they will undergo surgery. Specimens obtained from surgery will be used to evaluate the predictive value of the PET scan. Participants will be scheduled to clinic visits for follow-up at 5 weeks after chemo-radiotherapy, 3 monthly for the first 12 months, and then 6 monthly thereafter until a minimum of 2 years. At each visit, apart from routine history and physical examination, participants will be asked to complete a series of short questionnaires which evaluate the health-related quality of life. This is a prospective, single arm, multi-centre study and a total of 200 participants will be recruited.
