About

This is a study to evaluate the efficacy and safety of neoadjuvant pembrolizumab plus chemotherapy in resectable locally advanced esophageal squamous cell carcinoma patients

Full description

The primary objective of the study is to assess the tumor response (by irRECIST) and pathological response of neoadjuvant pembrolizumab plus chemotherapy (carboplatin, paclitaxel).

Secondary objectives are:

To assess completion of neoadjuvant pembrolizumab plus chemotherapy. To assess toxicities of neoadjuvant pembrolizumab plus chemotherapy To assess completion of neoadjuvant pembrolizumab plus chemotherapy. To assess withdrawal rate from surgery. To assess delay rate from surgery. To assess R0 resection rate. To assess post-operative complications. Progression Free Survival.

Tumor length longitudinal ≤ 10 cm; if larger than 10 cm, inclusion should be discussed with the principal investigator.
18≤Age.
Tumor does not involve gastro-esophageal junction.
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
Adequate hematological, renal and hepatic functions defined as:

neutrophiles ≥ 1.5 x 109/L platelets ≥ 100 x 109/L alanine transaminase≤2 x upper normal limit hemoglobin ≥ 5.6 mmol total bilirubin ≤ 1.5 x upper normal limit creatinine clearance (Cockcroft) ≥60 ml/min

Exclusion criteria
