Abstract:
BACKGROUND:Esophageal cancer represents a heterogeneous malignancy mostly diagnosed in advanced stages. Worldwide, squamous cell carcinomas (SCCs) continue to be the most prevalent subtype; however, in the Western countries, the incidence of adenocarcinomas is increasing and will exceed that of SCC in the near future. During the last decade, several landmark trials contributed to a better understanding of the disease and emphasized the importance of multimodal treatment protocols. SUMMARY:With the introduction of perioperative or neoadjuvant approaches, the survival of both subtypes of esophageal cancer has significantly improved. Several trials confirmed a survival benefit for perioperative chemotherapy or neoadjuvant chemoradiation, respectively, for patients with resectable locally advanced adenocarcinomas. However, the question of whether perioperative chemotherapy or neoadjuvant chemoradiation is more effective for the long-term survival in this population has yet to be fully elucidated. In SCCs, neoadjuvant chemoradiation followed by surgery or definitive chemoradiation in case of functional inoperability represent the preferred treatment options. Compared to neoadjuvant protocols, adjuvant chemotherapy or chemoradiation have only minor effects and are associated with enhanced toxicities. Current preclinical and clinical trials investigate efficacy and tolerability of novel drugs aiming to modulate immune check-points and dual inhibition of HER2. In this "to-the-point" article, we review the current standard and summarize the most recent and encouraging therapeutic advances in esophageal cancer. Multimodal treatment approaches for esophageal cancer should be discussed in a multidisciplinary team based on histology, tumor localization, and patient performance status. Neoadjuvant chemoradiation is beneficial for patients with locally advanced SCC and adenocarcinomas of the esophagus and the gastroesophageal junction (GEJ), with perioperative chemotherapy representing a valid alternative for GEJ adenocarcinomas. Combination therapies are indicated for metastatic adenocarcinomas, while the benefit of palliative chemotherapy in SCC remains controversial. Trastuzumab is indicated in HER2+ metastatic adenocarcinomas.
