Perioperative therapy landscape for locally advanced, resectable esophageal cancer: an updated literature review.

Background and Objective: The poor oncologic outcomes associated with esophageal cancer (EC) are primarily due to its presentation at an advanced stage and patient comorbidities. While multimodal therapy improves overall outcomes, there is a lack of uniform practice in terms of perioperative management, partly because this is a rapidly evolving field in a heterogeneous patient population. With numerous recent studies incorporating precision medicine with radiographic, pathologic, and genomic biomarkers and with emerging trials using targeted therapies, it is necessary for providers who care for these patients to be familiar with the current and evolving treatment standards to optimize patient outcomes. The objective of this paper is to perform an updated review of the main historical and recently emerging studies that impact the perioperative management of patients with locally advanced, upfront-resectable EC. Methods: We mined and reviewed PubMed and American Society of Clinical Oncology databases for pivotal works shaping the current perioperative treatment landscape in locally advanced EC. Key Content and Findings: EC are a vastly heterogeneous disease, and treatment options vary based on tumor anatomic location, histology, and patient comorbidities. Perioperative chemotherapy (CTX), chemoradiation (CRT), and, recently, immunotherapy have improved survival in patients with locally advanced disease. However, optimizing sequencing, de-escalating therapy, and incorporating novel targeted therapies in the perioperative setting are promising strategies that are under ongoing investigation to improve patient outcomes further. Conclusions: There is an ongoing need to identify predictive biomarkers and novel treatment strategies to personalize perioperative approaches and optimize outcomes of patients with EC.
