Comparing Right and Left Thoracic Surgery for Locally Advanced Siewert II Gastroesophageal Junction Adenocarcinoma After Chemotherapy

What this Trial Is About

Researchers are evaluating the five-year overall survival of two different surgical approachesthe right versus left thoracic methodsfor patients with locally advanced Siewert II gastroesophageal junction adenocarcinoma who have been treated with neoadjuvant chemotherapy. The study focuses on comparing these approaches in patients with specific tumor stages and operative conditions to understand which may offer better outcomes. Participants receive a combination of treatments starting with neoadjuvant chemotherapy consisting of 2 to 4 cycles, followed by surgery using either the right thoracic approach or the left thoracic approach, which involves different surgical incisions and lymph node removal. After surgery, patients continue with adjuvant chemotherapy to complete a total of 8 cycles including the initial neoadjuvant treatment. During the study, participants will be monitored for overall survival over five years, as well as disease-free survival over three years, pathological response rates shortly after surgery, and any operative complications during the perioperative period. The study involves multiple assessments to evaluate these outcomes, with careful follow-up to track the long-term effects and safety of the surgical approaches.
