Statistical Analysis Plan for the SANO-trial: Neoadjuvant Chemoradiotherapy Followed by Surgery Versus Active Surveillance for Oesophageal Cancer
Sponsor: Erasmus Medical Center
Summary
An active surveillance approach is proposed after completion of neoadjuvant chemoradiotherapy (nCRT) for carcinoma of the oesophagus. In this SANO (i.e. Surgery As Needed for Oesophageal cancer) approach, surgical resection is offered only to patients in whom a locoregional regrowth is highly suspected or proven, without distant dissemination. Such an organ-preserving strategy can have great advantages, but is only justified if long-term survival is non-inferior to that of the current standard trimodality approach comprising neoadjuvant chemoradiotherapy followed by standard surgery. The aim of this study is to assess the (cost-)effectiveness (including non-financial costs and survival) of active surveillance for patients with squamous cell- or adenocarcinoma of the oesophagus or oesophago-gastric junction.

Interventions
Active surveillance
Patients enrolled in the active surveillance arm will undergo diagnostic evaluations every 3 months in the first year after completion of neoadjuvant treatment, every 4 months in the second year, every 6 months in the third year and yearly in the 4th and 5th year of follow up, or when symptoms or results of any diagnostic test require shorter assessment intervals. In the active surveillance arm, surgical resection will be offered only to those patients, in whom a locoregional regrowth is highly suspected or proven, without any signs of distant dissemination.
