This phase I study aimed to assess the safety, dose‐limiting toxicity (DLT), maximum tolerated dose (MTD) and preliminary effect of nanoparticle albumin‐bound (nab)‐paclitaxel in combination with concurrent chemoradiotherapy in patients with locally advanced esophageal squamous cell carcinoma (ESCC). Here, ALB is linked to esophageal squamous cell carcinoma.
