Prognostic Analysis of Esophageal Cancer with Complete Pathological Response After Neoadjuvant Therapy
Sponsor: Cancer Institute and Hospital, Chinese Academy of Medical Sciences
Summary
Esophageal cancer is one of the most common malignant tumors worldwide, with high invasiveness and lethality. Currently, the treatment for resectable locally advanced esophageal cancer mainly consists of a treatment model centered on surgical treatment with the participation of multiple disciplines. Neoadjuvant treatment regimens include chemotherapy, chemoradiotherapy, and chemotherapy combined with immunotherapy. Complete pathological response (pCR)is currently regarded as one of the important indicators for evaluating the efficacy of neoadjuvant treatment. Previous studies have shown that 14%-39% of patients with complete pathological response after neoadjuvant treatment still experience recurrence and metastasis within two years after surgery, suggesting that pCR after esophageal cancer surgery does not mean clinical cure. Perhaps there is a highly risk clinical subgroup need to research. Therefore, based on the prospective clinical database of the National Cancer Center and in cooperation with multiple national cancer regional medical centers, this study analyzes and explores the prognosis of patients with locally advanced esophageal squamous cell carcinoma with pCR after neoadjuvant treatment, characterized by the Chinese population.
