Guidelines suggest that the serum carbohydrate antigen (CA19-9) level should be used when deciding on neoadjuvant treatment in patients with resectable and borderline resectable pancreatic ductal adenocarcinoma (hereafter referred to as pancreatic cancer). In patients with resectable pancreatic cancer, neoadjuvant therapy is advised when the CA19-9 level is 'markedly elevated'. This study investigated the impact of baseline CA19-9 concentration on the treatment effect of neoadjuvant chemoradiotherapy (CRT) in patients with resectable and borderline resectable pancreatic cancers. ⋯ Baseline serum CA19-9 level defined as either high or low has prognostic value, but was not associated with the treatment effect of neoadjuvant CRT in patients with resectable and borderline resectable pancreatic cancers, in contrast with current guideline advice.

RCTs are essential in guiding clinical decision-making but are difficult to perform, especially in surgery. This review assessed the trend in volume and methodological quality of published surgical RCTs over two decades. ⋯ The volume of published surgical RCTs worldwide remained stable in the past decade but their methodological quality improved. Considerable geographical shifts were observed, with Asia and especially China leading in terms of volume. Individual European countries are leading in their relative volume and methodological quality of surgical RCTs.

Active surveillance is being investigated as an alternative to standard surgery after neoadjuvant chemoradiotherapy for oesophageal cancer. It is unknown whether dysphagia persists or develops when the oesophagus is preserved after neoadjuvant chemoradiotherapy. The aim of this study was to assess the prevalence and severity of dysphagia during active surveillance in patients with an ongoing response. ⋯ Dysphagia and clinically relevant stenosis are uncommon during active surveillance.
