Randomized Controlled Trial Multicenter Study
Effects on heart function of neoadjuvant chemotherapy and chemoradiotherapy in patients with cancer in the esophagus or gastroesophageal junction - a prospective cohort pilot study within a randomized clinical trial.
Neoadjuvant therapy for cancer of the esophagus or gastroesophageal (GE)-junction is well established. The pros and cons of chemoradiotherapy and chemotherapy are debated. Chemoradiotherapy might impair cardiac function eliciting postoperative morbidity. The aim of this pilot study was to describe acute changes in left ventricular function following chemoradiotherapy or chemotherapy. ⋯ Neoadjuvant chemoradiotherapy but not chemotherapy before surgery for cancer of the esophagus or GE-junction seems to induce an acute negative effect on both systolic and diastolic left ventricular function. Future studies on neoadjuvant treatment for esophageal cancer are suggested to add measurements of cardiac function.
